Summary

Changes

• iOS WatchConnectivity synchronization and monitor credential transport: The phone app now owns one WatchConnectivity instance, persists/pushes selected monitor servers with scoped tokens, imports legacy URLs, handles watch requests/activation, and integrates watch selection with server lifecycle and iOS settings.
• SSH credential resolution, host-key trust, jump chains, and editor/settings behavior: SSH utilities now resolve imported keys versus filesystem IdentityFile paths, clean up failed authentication sockets, detect jump cycles/failover, normalize and serialize host-key fingerprints, serialize prompts, expose known-host management, and preserve editor/config-import behavior.
• AI conversation persistence, shared Agent session, tool execution, and Ask AI presentation: The app-wide Agent gains typed timeline/replay state, conversation watching and persistence, pending-tool restoration/auto-run rules, shared locale/protocol handling, while the per-server Ask AI panel gains responsive presentation, history, command lifecycle, output limits, and cancellation.
• Backup/sync security, store-provider updates, and app initialization/migration: Backup UI enforces encryption for remote sync and improves async dialog/status/import handling; providers trigger backup sync and watch/server updates; startup ordering and migration handling are adjusted.
• Tab restoration and session identity: File and SSH tab restoration is moved/validated around durable history records, preserving multiple sessions, local-platform support, per-tab paths/tmux state, malformed-entry tolerance, and closed-versus-started behavior.
• Rust FFI dependency and macOS build/deployment gate: The FFI crate dependency manifest and macOS workflow are updated to build the unsandboxed macOS application with pinned toolchain/dependency inputs and native Rust linkage.
• Monitor agent authentication, watch tokens, remote access, and persistence: The monitor backend adds hashed expiring/revocable watch credentials, authentication timing/throttling changes, capability and remote-access responses, synchronized config writes, bounded notification delivery, and related database/install/runtime behavior.
• Monitor web panel API, polling, server management, and release frontend: The monitor frontend changes server URL/auth handling, polling and concurrency, probing/health state, dashboard/server forms, naming, and associated browser tests.
• Localization and generated resource contract: Localized strings and generated localization Dart outputs are updated for backup, SSH host keys/config import, watch, Agent/Ask AI, and monitor-facing UI text.

📝 Walkthrough

Walkthrough

This pull request adds scoped watch tokens and replaces watch password transfer with read-only tokens. It enforces secure remote endpoints and canonical host-key fingerprints. It updates monitoring storage, notification handling, frontend polling, Flutter persistence, backups, localization, CI workflows, release workflows, tests, and website metadata. It also updates submodule references.

Merge Risk: 🟠 High · up to 997e6

The PR changes monitor/watch authentication, server refresh and reset flows, and conversation persistence, but the current head can still invalidate watch re-pairing, skip server refreshes, report state-clearing success without durable completion, and create duplicate or non-durable AI conversations. These concrete correctness, availability, and data-integrity risks should be fixed or explicitly accepted before merging.

CI failure root-cause analysis

The frontend failure is caused by packages/webui/src/utils.ts importing clsx when the frontend test environment cannot resolve that package. The Rust job has no actionable compiler diagnostic: the listed test suites all pass, followed only by build failed, so its root cause cannot be determined from the supplied output.

Attribution

No specific causing change can be attributed from the supplied diagnostics.

Verifiable fix

Add or restore clsx as a dependency available to the frontend workspace/package, or change packages/webui/src/utils.ts to use an existing dependency; verify with the frontend test command and dependency-resolution check. For job 95962040640, inspect the omitted earlier compiler/build diagnostic before proposing a fix.

Incremental value: root cause, attributed to this change, verifiable fix; confidence 98%. Passing CI ≠ absence of defects (§29.4).

Consider dropping the deprecated compatibility surface inside this repository.

HostKeyPromptInfo keeps fingerprintHex, fingerprintBase64, and previousFingerprintHex. Line 591 still reads info.fingerprintHex for the prompt dedupe key. Deprecated member use in the same package raises the deprecated_member_use_from_same_package lint and can fail flutter analyze. Update line 591 to info.fingerprint. If no external package consumes this class, remove the deprecated members.

Add coverage for the raw digest branch.

key(seed) always produces UTF-8 bytes of a formatted SHA256: string. That input exercises only the first branch of fingerprintToOpenSsh. The 32-byte raw digest branch and the MD5: fallback stay untested. Older dartssh2 versions pass raw digest bytes, so that branch is a real runtime path.

Add one case that passes a raw 32-byte Uint8List and expects the same value as fingerprintOf(seed).

🧪 Proposed additional case

test('accepts raw 32-byte digests from older dartssh2', () {
  final digest = Uint8List.fromList(
    List<int>.generate(32, (index) => (3 + index) & 0xff),
  );

Add a test for the lost-race branch.

The new branch runs only when INSERT OR IGNORE affects zero rows. The existing tests never reach it, because each test performs the first insert itself. You can reach the branch deterministically without threads: insert a row for the address directly with sqlx::query, then call verify with a different key and assert Verdict::Mismatch, and with the same key and assert Verdict::Known.

Inline comments:
In @.github/workflows/analysis.yml:
- Around line 161-163: Update both validation-job checkout steps in
.github/workflows/analysis.yml at lines 161-163 and 204-206 to set submodules:
recursive, ensuring packages/webui is available for the monitor frontend and
website prebuild hooks.

In `@ios/WatchApp/Store.swift`:
- Around line 40-47: Update the cleanup logic around tokenAccounts() so
legacyPasswordService accounts are enumerated independently and deleted for
every server ID no longer present in live. Preserve the existing snapshot and
new-token cleanup, and ensure stale legacy password records are removed via the
existing credential-deletion mechanism.

In `@lib/core/service/watch_sync.dart`:
- Around line 125-157: The watch-sync flow must not reuse a token when the
server’s monitor address has changed. Update _existingTokens and its callers
around payloadFrom to retain each prior token’s originating normalized endpoint,
remove mismatched tokens before issueWatchToken, and preserve reuse only when
the stored endpoint matches the current monitor.addr.
- Around line 123-145: Update the watch-server removal and unpair flows, using
buildPayload and the existing MonitorHttpClient token APIs, to revoke each
server’s watch token via DELETE /api/v1/watch-token with client_id
watch:${spi.id} before removing or deselecting the server. Ensure cleanup also
runs when the watch is unpaired, while preserving payload generation for
remaining servers.

In `@lib/core/sync.dart`:
- Around line 38-39: Replace the hardcoded backup-password error in
lib/core/sync.dart lines 38-39 with the appropriate libL10n or l10n localization
symbol. Replace the endpoint-policy error literal in
lib/data/provider/server/monitor_http.dart lines 40-44 similarly, add the
corresponding ARB entries, and regenerate localization output with flutter
gen-l10n.

In `@lib/data/provider/ai/agent_session.dart`:
- Around line 198-211: Update submitPrompt so it reserves a submission before
the first await, preventing concurrent calls from both passing the initial state
checks and creating competing conversations or streams. Use an in-flight guard
or set recoverable working state before _ensureConversation(), and ensure the
reservation is cleared if _persist() fails.

In `@lib/data/provider/server/all.dart`:
- Around line 178-183: Convert the result of serversToRefresh.length.clamp(0,
_maxConcurrentRefreshes) to int before passing it as the count to List.generate
in the worker refresh flow.

In `@lib/data/store/cached_store.dart`:
- Around line 104-134: Propagate async through addServer and the related server,
snippet, and private-key provider flows; await every Stores.server.put,
deleteById, clear, and update mutation before calling bakSync.sync or reporting
success, and await each bulk-import write in the backup flow before returning
success. Preserve existing error propagation so persistence failures are not
left unhandled.

In `@lib/view/page/agent/view.dart`:
- Around line 297-308: Add serialization to AgentSession.submitPrompt so
concurrent calls cannot both pass the working-state check while setup or
persistence awaits; use an in-flight guard or mutex that is released on every
completion path. Preserve prompt handling semantics, and add a test covering
rapid double submission to verify only one prompt is persisted and streamed.
- Around line 304-310: Update _submitPrompt to check mounted after awaiting
_notifier.submitPrompt and before calling _inputController.clear(), while
preserving the existing success condition.

In `@lib/view/page/ssh/page/ask_ai.dart`:
- Around line 427-430: Update _ensureConversation to deduplicate concurrent
creation by caching and reusing an in-flight Future<AgentConversation> when
_conversation is null. Ensure only one Stores.agentConversation.create operation
runs at a time, both callers receive the same conversation, and the cached
in-flight state is cleared appropriately after completion.
- Around line 464-467: Update _submitPrompt to use a submission-in-flight guard
set before awaiting _ensureConversation, reject subsequent submissions while
that guard is active, and clear it in a finally block so it resets on both
success and failure. Preserve the existing checks for empty prompts, _isWorking,
and _pendingCommand.
- Around line 467-476: Update _submitPrompt and _runPendingCommand to check
mounted immediately after each awaited operation before calling setState or
starting streaming. Guard the UI updates after _ensureConversation and the
_startStream calls after _persistConversation so no actions run after the State
is disposed.
- Line 679: Restrict the command failure try/catch around widget.onCommandRun so
persistence errors cannot be reported as command failures. Move await
_persistConversation() outside that catch, and handle its failures separately
without retrying persistence from the command catch path.
- Line 519: Update the stream subscription around _handleEvent so events are
processed serially and handler failures flow through the stream’s onError path;
use asyncMap or an equivalent explicit queue before listen, ensuring
_persistConversation executes within that serialized processing sequence.

In `@monitor/frontend/src/pages/Dashboard.svelte`:
- Around line 105-128: Reset poller state whenever its identity changes: clear
data and error before restarting status and metrics for a new servers.currentId,
and before restarting historyPoller for a new server or rangeMinutes. Preserve
the existing authenticated polling guards and cleanup behavior, and add coverage
that switches authenticated servers and history ranges after successful requests
to verify stale results are not displayed.

In `@monitor/src/core/config_file.rs`:
- Around line 143-158: Update the default-creation and JSON-migration paths in
the config handling code to use the existing private writer, such as
write_private_new, instead of direct fs::write calls when creating config.toml.
Preserve the current contents and flow, and add coverage verifying both paths
create the file with private permissions.
- Around line 107-116: Update the atomic configuration writer around the
temporary-file creation and fs::rename flow to sync the containing parent
directory after a successful rename, propagating any directory-sync error. In
Config::load and handle_config, replace direct config.toml writes with this
atomic writer so all configuration persistence preserves durability and the
private-file policy.

In `@monitor/src/db/bootstrap.rs`:
- Around line 12-32: Update write_initial_credentials to place
INITIAL_CREDENTIALS_FILE alongside the configured database directory rather than
using the process working directory, threading that path or an explicit setting
from ensure_admin_user as needed. Handle an existing stale credentials file and
permission failures with actionable errors while preserving secure file
creation; account for Windows ACL behavior separately from the Unix 0o600 mode.

In `@monitor/src/monitoring/push.rs`:
- Around line 343-344: Update send_ios_notification to reject any response where
status_code.is_success() is false before applying the optional config.code
expected-code check, while preserving the response_text handling and success
path for successful responses.

• Cargo.lock is excluded by !**/*.lock

⚠️ Unverified risks (2)

• System-mode installs leave configuration and its credentials readable by other local users. The installer creates /opt/server-box-monitor with default directory mode (typically 0755), copies config.example.toml/.env.example with default modes, and does not restrict config.toml; operators commonly add push tokens or other secrets to that runtime config, so a non-root local user can read them. (monitor/install.sh)
• Browser TOFU is raceable across simultaneous connections that start with separate cache snapshots. genClient copies the global store before constructing each verifier; two connections that see no pin can both prompt, and if they receive different offered keys, promptHostKeyExclusively merely serializes the dialogs rather than re-reading or atomically claiming the pin. Each verifier then writes its own key and returns true, while the serialized persistence queue eventually leaves whichever key was persisted last. Thus both a legitimate key and a concurrent impostor can be accepted during first use, and the second prompt is shown as isMismatch: false instead of comparing against the first winner. This would be proven false only if all concurrent genClient calls are guaranteed to share one mutable cache or the underlying SSH callback cannot concurrently offer different keys. (lib/core/utils/server.dart)

📋 Additional findings from this change (not shown inline) (73)

• 🟠 High Removing a symlink removes its canonical target rather than the symlink entry itself, contrary to the endpoint's documented remove semantics; a link inside one configured root can therefore delete a file or directory in another configured root. (monitor/src/api/fs.rs) — anchor-unreliable
• 🟠 High DELETE /api/v1/fs/remove can delete the target of an in-root symlink instead of deleting the symlink itself. remove calls resolve_existing, which canonicalizes every symlink, and then calls symlink_metadata/remove_dir_all on that canonical target; for /srv/root/link -> /srv/root/important, a request for /srv/root/link becomes /srv/root/important and removes the target. This violates the handler's stated “a link is deleted, never followed” invariant and can turn a harmless shortcut deletion into destructive deletion of another in-root tree. The claim would be false if resolve_existing preserved the final directory entry (or if the target could not be removed by the resulting operation). (monitor/src/api/fs.rs) — anchor-unreliable
• 🟠 High A late 401 from a previously selected server can log out the newly selected server. If a poll/request for A is in flight and the user switches to B before A responds, request() receives A's 401 but calls servers.logout(), whose implementation clears servers.current (now B), thereby deleting B's valid token and sessionStorage entry. (monitor/frontend/src/lib/api.ts) — anchor-outside-diff
• 🟠 High A successful jump connection leaks the jump SSHClient and leaves it owning the forwarding transport with no lifecycle owner: the local variable is only closed in the catch path, while the successful path returns the forward channel and discards jumpClient. When the target client is later closed or the connection is disposed, there is no retained jump client to close, so the jump SSH session/socket can remain alive indefinitely. (lib/core/utils/server.dart) — anchor-outside-diff
• 🟠 High TFA submission is not bound to the session generation that produced its challenge. submitTfaCode captures only _pendingTfaChallenge, then after awaits calls _loginWithTfaChallenge and performs _getRelease/list with only ref.mounted checks. If the user reconnects after the challenge dialog opens, the captured old challenge is sent through the replacement session and the result can set current state/auth headers or close/publish errors for the new generation. (lib/data/provider/pve.dart) — anchor-outside-diff
• 🟠 High Specialized SFTP staging names are not unique across concurrent transfer isolates, so one transfer can overwrite or delete another transfer's in-progress staging file. (lib/data/model/file/transfer_worker.dart) — anchor-outside-diff
• 🟠 High A download idle timeout races the still-running SFTP read: Future.any returns on the timeout, then the finally block closes the local file and later the SFTP resources while downloadFuture is not cancelled or awaited. The outstanding read can write to a closed file, produce unhandled errors, or continue consuming resources after the transfer has reported failure. (lib/data/model/file/transfer_worker.dart) — anchor-outside-diff
• 🟠 High The SFTP replacement fallback deletes the existing destination after any failed rename for which stat(path) succeeds, without establishing that the failure was caused by an existing destination. A permission, transport, or server-side rename failure can therefore turn a failed transfer into loss of the previously good destination, and the second rename can fail leaving neither file. (lib/data/model/file/transfer_worker.dart) — anchor-outside-diff
• 🟠 High The monitor backend treats FileBackend.write's optional size hint as an authoritative HTTP Content-Length. runCopy passes a listing/stat-derived size, but the interface explicitly says that value is only a hint and the source can change while it is being read. If the actual stream length differs, the agent's HTTP payload framing can terminate early or wait/fail instead of consuming the stream, so a valid copy can be rejected or committed with a truncated body; the monitor implementation does not validate the byte count before renaming.

• 🟠 High Concurrent transfers to the same destination can reuse the same staging pathname and corrupt or delete each other's work. (lib/data/model/file/transfer_worker.dart) — per-file-budget
• 🟠 High The newer-schema refusal is not scoped to the sync attempt and can be bypassed by an overlapping sync, allowing an older copy to overwrite a newer remote file. fromFile clears the singleton marker at the start of every read, while backup later consults the shared marker; for example, sync A reads a too-new remote and yields after setting _remoteTooNew, sync B starts/reads any ordinary remote and clears it, then A reaches backup and uploads. The same singleton is used by automatic sync callers, so this is not limited to a UI double-tap. This is introduced by the static marker-based refusal design; it would be false only if SyncIface.sync serialized all calls globally and no other fromFile could run before the first call's backup decision. (lib/core/sync.dart) — anchor-outside-diff
• 🟠 High Upgrading from a malformed or incomplete package can permanently remove the working frontend and migrations and still report success. SBM_INSTALL_PKG is accepted after checking only the binary, while install_files deletes the existing frontend and migrations before copying those package paths; because the script does not use set -e or check the cp results, missing paths leave the service running without its panel/migrations and upgrade prints success. (monitor/install.sh) — anchor-outside-diff
• 🟠 High An explicitly empty current configuration is resurrected from the legacy ctx on every watch process launch. PhoneConnMgr.init runs migrateLegacyCtx() whenever the decoded server list is empty, but migration never removes ctx or records that migration was attempted. Thus after the phone sends an empty servers/urls payload (user cleared all watch servers), the next PhoneConnMgr initialization repopulates the old URLs and displays servers the user removed. This would be false only if some other code deletes UserDefaults.standard["ctx"] or writes a persistent migration marker when the empty payload is applied; no such code is present in the reviewed implementation. (ios/WatchApp/PhoneConnMgr.swift) — anchor-outside-diff
• 🟠 High A login response can be stored on the wrong server entry if the user changes the selected server while the request is in flight. api.login() reads servers.current when constructing the request, but LoginForm calls servers.login() after await, and login() uses the then-current currentId; logging into A followed by selecting B before the response stores A's token on B and leaves A unauthenticated. (monitor/frontend/src/components/LoginForm.svelte) — anchor-outside-diff
• 🟠 High Forgetting a host key can be undone by an already queued acceptance write. persistHostKeyFingerprint serializes writes through _hostKeyPersistence, but forgetHostKeyFingerprints reads the store and calls prop.put directly outside that queue. If an accepted key write is queued, the user forgets the server before it runs, and then the queued callback executes, it writes the accepted key back after the forget operation, so the next connection silently trusts it again. (lib/core/utils/server.dart) — anchor-outside-diff
• 🟠 High A stale list() request can tear down a newer PVE session during reconnect. list has no generation/session identity, so if its request from generation N fails after reconnect() has incremented _sessionGeneration and installed generation N+1, the connection-failure branch unconditionally calls _closeSession; that closes the current Dio, ServerSocket, and forwards for N+1 and leaves the new init disconnected. This is proven false only if callers can guarantee no list request survives a reconnect (including the init-triggered list and timer/UI calls). (lib/data/provider/pve.dart) — anchor-outside-diff
• 🟠 High The installer preserves an existing .env without repairing its permissions. An existing world-readable .env (for example from a legacy install or a manual copy) remains readable by all local users, while it may contain JWT_SECRET and push credentials; chmod 600 is performed only in the newly-created-file branch. (monitor/install.sh) — anchor-outside-diff
• 🟠 High A stale Proxmox list request can tear down a replacement session. list() does not capture or validate _sessionGeneration; on a connection failure it unconditionally calls _closeSession. If reconnect() or a provider client replacement has already created a new forwarding/session generation while the old cluster/resources request is still pending, the old request's failure enters this branch and closes the new Dio session, server socket, and forwards, then publishes disconnected state for the current connection. (lib/data/provider/pve.dart) — anchor-unreliable
• 🟠 High SFTP overwrite can permanently delete the good destination when the replacement rename fails after the fallback removal. _replace removes path and then performs a second rename without restoring or retaining the old file; any permission, quota, disconnect, or other error on that second rename leaves neither the old destination nor the new file. This violates FileBackend.write's atomic replacement/integrity contract for servers without the POSIX rename extension. (lib/core/utils/sftp_file_backend.dart) — anchor-unreliable
• 🟠 High Browser TOFU is raceable across simultaneous connections that start with separate cache snapshots. genClient copies the global store into hostKeyCache before constructing each verifier; two connections that see no pin can both prompt, and if they receive different offered keys, promptHostKeyExclusively merely serializes the dialogs rather than re-reading or atomically claiming the pin. Each verifier then writes its own key and returns true, while the serialized persistence queue eventually leaves whichever key was persisted last. Thus both a legitimate key and a concurrent impostor can be accepted during first use, and the second prompt is shown as isMismatch: false instead of comparing against the first winner. This would be proven false only if all concurrent genClient calls are guaranteed to share one mutable cache or the underlying SSH callback cannot concurrently offer different keys. (lib/data/provider/server/single.dart) — anchor-unreliable
• 🟡 Medium Expired watch-token rows are never cleaned up. Migration 007 adds an expiry index, and verification excludes rows with expires_at <= now, but the only scheduled cleanup calls metrics, alerts, policy tables, and size-capped time-series cleanup; it never deletes from watch_tokens. An authenticated caller can issue tokens for an unbounded series of distinct client IDs, leaving one row per client permanently after the 90-day expiry and growing the database/index indefinitely. This violates the data-integrity/cleanup obligation; it would be false if another startup or cleanup path not present here deletes expired watch_tokens. (monitor/src/db/cleanup.rs) — anchor-outside-diff
• 🟡 Medium A database upgraded with migration 007 cannot be opened by a downgraded binary whose embedded migrations stop at 006. db::database::init always runs the embedded SQLx migrator, while SQLx migration execution has no downgrade path and the older migrator has no migration 007 to reconcile the _sqlx_migrations row. On rollback of the monitor binary, startup therefore fails before the server is usable, violating the stated downgrade/compatibility expectation. This would be disproven if the supported downgrade procedure explicitly removes/reverts migration 007 or the older binary embeds a compatible migration history. (monitor/src/db/database.rs) — inline-budget
• 🟡 Medium Token rotation can revoke the watch's currently working credential before the new payload is durably delivered. Each push issues a new token first; the backend upserts (subject, client_id), replacing the old hash, and only afterward does _pushOnce call updateApplicationContext. If context delivery fails (unpaired/transient WatchConnectivity error), the watch still has the old token but the agent has already invalidated it, causing an outage until a later successful push. (lib/core/service/watch_sync.dart) — inline-budget
• 🟡 Medium Legacy URL migration can be permanently skipped when the first launch has no old application context. _importLegacyUrls sets watchLegacyUrlsImported to true whenever urls is null or empty, so a launch racing activation/context delivery (or a pre-v2 install with context not yet available) will never retry and the old URLs are lost. (lib/core/service/watch_sync.dart) — inline-budget
• 🟡 Medium Malformed/duplicate server IDs are accepted into the watch list, producing duplicate SwiftUI identities and ambiguous token ownership. PhoneConnMgr.parse validates nonempty IDs but never rejects a repeated ID, while WatchSync.payloadFrom likewise emits one entry per repeated selected ID; ContentView renders ForEach(..., id: \.element.id), so duplicate entries violate the identity invariant and the token dictionary's last duplicate silently wins. (ios/WatchApp/PhoneConnMgr.swift) — inline-budget
• 🟡 Medium Replacing/removing a server leaves its URLSession (and therefore its MonitorClient and connection pool) permanently retained, leaking resources over time. (ios/WatchApp/MonitorClient.swift) — inline-budget
• 🟡 Medium Legacy keychain credentials are not fully cleaned when a server is removed. setServers enumerates only accounts under the new keychainService; it calls setToken(nil, for:) only for those accounts absent from the live server IDs. Credentials left under legacyPasswordService are never enumerated, so an old-build token for a removed server survives indefinitely (and the cleanup in setToken is never reached for that ID). This would be false only if the old service is guaranteed to contain no accounts on upgrade or another migration enumerates and deletes that service; the reviewed Store has no such enumeration or cleanup. (ios/WatchApp/Store.swift) — inline-budget
• 🟡 Medium The watch accepts duplicate server IDs and passes them to a SwiftUI ForEach whose identity is the server ID, producing non-unique page identities and potentially rendering/loading the wrong page. parse appends every valid entry without tracking IDs, while ContentView uses id: \.element.id; a malformed/retried payload or duplicated persisted selection can therefore create two entries with the same identity, and token/snapshot storage also collapses them by ID. This would be false only if WatchConnectivity/payload producers enforce uniqueness for all future payloads; the parser itself has no such invariant check and the persisted selection is not validated here. (ios/WatchApp/PhoneConnMgr.swift) — inline-budget
• 🟡 Medium The frontend accepts HTTPS/loopback URLs containing a query or fragment, then appends the API path after that delimiter, so requests are sent to the wrong URL rather than the configured server API. (monitor/frontend/src/lib/agentUrl.ts) — inline-budget
• 🟡 Medium A late 401 from an explicit request for server A can log out whichever server is currently selected, including server B, because the generic request helper logs out through mutable global selection rather than the server whose token was used. (monitor/frontend/src/lib/api.ts) — inline-budget
• 🟡 Medium Explicit-server capability and name probes do not invalidate the probed server's session on 401, so a revoked/expired non-selected token remains stored in sessionStorage and is repeatedly treated as authenticated. (monitor/frontend/src/lib/api.ts) — inline-budget
• 🟡 Medium Each monitor WebSocket upgrade allocates a fresh HttpClient and discards it without closing it, so repeated terminal/tunnel reconnects leak client/socket-pool resources until process shutdown. (lib/data/provider/server/monitor_http.dart) — inline-budget
• 🟡 Medium Rapid card reorders can be persisted out of order. onCardDrop fires api.updateCardOrder(cardOrder) without awaiting or serializing the previous write; if the first PUT is delayed and the second arrives first, the first stale order can arrive last and become the server's final order, so a reload/other client loses the user's latest arrangement. (monitor/frontend/src/pages/Dashboard.svelte) — inline-budget
• 🟡 Medium ensureKnownHostKey treats any cached key type as sufficient and can skip verification of the negotiated algorithm. _hasKnownHostFingerprintForSpi only checks for an identity prefix, so a stored ssh-ed25519 key causes ensureKnownHostKey to return before connecting even when the server/client will negotiate ssh-rsa (or another type) whose fingerprint has never been trusted. This violates exact identity-plus-key-type trust and can make the preflight report success without verifying the key type actually used. (lib/core/utils/server.dart) — inline-budget
• 🟡 Medium ensureKnownHostKey treats any remembered key for a server as sufficient, even when it is for a different SSH host-key algorithm. This contradicts the per-key-type trust contract: a server with only srv::ssh-ed25519 remembered can offer RSA and the preflight returns without opening/verifying it, so callers relying on this preflight do not get the required prompt for the negotiated key. (lib/core/utils/server.dart) — inline-budget
• 🟡 Medium ensureKnownHostKey does not honor jump-server failover while recursively preflighting unknown jump hosts: it awaits the first unresolved candidate and propagates its error instead of trying the next candidate. With jump candidates [unreachable A, reachable B] and neither fingerprint cached, preflight fails before genClient can apply its failover loop, so a valid fallback path is rejected. (lib/core/utils/server.dart) — inline-budget
• 🟡 Medium Forgetting a host key can be undone by an already queued acceptance write. persistHostKeyFingerprint serializes writes in _hostKeyPersistence, but forgetHostKey/forgetHostKeyFingerprints directly read and put the store without joining that queue. If a user accepts a key (or a queued normalization write is pending) and immediately deletes it from Known Hosts, the forget operation can complete first; the queued persistence then rereads the store and re-adds the accepted fingerprint. The UI reports the key as forgotten, but the next connection is silently trusted. This would be disproven only if the store guarantees these put operations are ordered behind the asynchronous prop.set queue, which this code does not await or connect to. (lib/core/utils/server.dart) — inline-budget
• 🟡 Medium Unknown or stale source sizes can produce progress above 100% in the generic copy path. planCopy makes totalBytes a lower bound and runCopy counts actual bytes, but _copy computes percent as transferred / total * 100 whenever total > 0 with no cap; a tree containing a known-size file plus an unknown-size or underreported file can report 150% (or more), violating the stated lower-bound progress contract and misleading completion UI. (lib/data/model/file/transfer_worker.dart) — inline-budget
• 🟡 Medium SFTP uploads never publish their remote staging path, so cancellation/disposal cannot record or clean the staged file. _upload assigns staging and writes it, but unlike _download and generic _copy it sends no TransferStaging event; if the worker is disposed or its isolate is killed during upload, the remote .sb-part file remains indefinitely and is invisible to the cancellation cleanup path. (lib/data/model/file/transfer_worker.dart) — inline-budget
• 🟡 Medium The local staged write cannot replace an existing destination on Windows. File.rename is used directly for the final commit, but Dart's Windows rename fails when the target already exists; consequently copying/overwriting an existing local file reports failure after successfully writing the staging file, instead of honoring write's documented 'replacing whatever was there' behavior. The same path works on Unix, making this a platform-specific integrity/functional regression in the new staging implementation. (lib/core/utils/local_file_backend.dart) — inline-budget
• 🟡 Medium A failed upload rename can delete an existing good destination even when the rename failed for permission, connection, or another non-collision reason. (lib/data/model/file/transfer_worker.dart) — inline-budget
• 🟡 Medium A successful later sync can remain permanently blocked by a stale newer-schema marker when the intervening attempt fails before fromFile runs. fromFile is the only place that clears _remoteTooNew, but backup returns immediately whenever the static marker is non-null; thus a too-new read followed by a remote list/download failure (or another sync path that never calls fromFile) leaves the marker set, and subsequent valid syncs silently skip upload until some read happens to clear it. The UI has no reset for this state, so recovery is not reliable. This would be false only if the superclass guarantees every failed sync always invokes fromFile before any future backup call, including list/download failures. (lib/core/sync.dart) — inline-budget
• 🟡 Medium Automatic WebDAV and Gist syncs can leave their loading controls stuck forever after a recoverable sync error. Each validator sets its notifier to true, awaits bakSync.sync, and only then sets it false; there is no try/finally. A download/auth/upload exception therefore propagates out of the validator while webdavLoading or gistLoading remains true, so the manual controls continue rendering SizedLoading.small and the user has no retry control from that page. This would be false only if SyncIface.sync is guaranteed never to throw for any remote failure (contradicted by the surrounding manual handlers' error handling). (lib/view/page/backup.dart) — anchor-unreliable
• 🟡 Medium Pending automatic or manual remote work can write to a disposed loading notifier after the BackupPage is removed. dispose immediately calls webdavLoading.dispose() and gistLoading.dispose(), but the automatic validators and manual handlers assign .value = false after awaits without checking mounted; navigating away while bakSync.sync, a list/download, or an upload is pending can therefore trigger a disposed-notifier exception during completion (and the async validator may also return into a disposed StoreSwitch). This would be false only if the notifier implementation permits writes after dispose and all remote operations are synchronously cancelled on route disposal. (lib/view/page/backup.dart) — inline-budget
• 🟡 Medium The new remoteTooNew state is never surfaced by the backup page, and the automatic switch is reported as successfully enabled even when upload was refused. BakSyncer.backup only logs and returns on a too-new remote, while each validator awaits bakSync.sync and then returns true; BackupPage contains no read of BakSyncer.remoteTooNew or error/toast path. Consequently an older device can show the provider enabled and stop retrying while the remote remains untouched, with no explanation to the user. This would be false only if SyncIface.sync independently inspects this static getter and presents a UI error, but no such integration exists in the changed page/code search. (lib/view/page/backup.dart) — inline-budget
• 🟡 Medium The provider-conflict checks are raceable, so two concurrent enable operations can both pass and enable conflicting backends. Each StoreSwitch validator reads the other preference before its asynchronous password dialog/sync; if WebDAV and Gist (or iCloud and WebDAV) are enabled nearly simultaneously, both can observe the other as false, then both return true and persist their own switch. Later automatic callers use remoteStorage, which silently chooses iCloud over WebDAV over Gist, while the user may believe both are active and different in-flight syncs can target different providers. This would be false only if StoreSwitch serializes validators globally or preference writes are transactionally mutually exclusive, neither established by this page. (lib/view/page/backup.dart) — anchor-unreliable
• 🟡 Medium Backup-page async operations can write to disposed loading notifiers after the page is removed. Each WebDAV/Gist handler sets webdavLoading or gistLoading in finally, while dispose() disposes that notifier; navigating away while a list/download/upload is pending therefore causes a post-dispose notifier write (and can surface an exception rather than merely cancelling the operation). (lib/view/page/backup.dart) — anchor-unreliable
• 🟡 Medium A failed encrypted remote read can still allow sync to overwrite the remote backup. fromFile catches every non-schema error (including a wrong, missing, or stale backup password while parsing a Cryptor-encrypted payload), then retries without a password; that retry also fails, but _remoteTooNew remains null. SyncIface's documented behavior is to upload after a merge/read failure, and backup() only blocks when _remoteTooNew is set, so the local copy can replace an unreadable encrypted remote instead of preserving it. (lib/core/sync.dart) — inline-budget
• 🟡 Medium inheritLegacyRemote does not perform the operation its own comment promises: after downloading and merging srvbox_bak.json, it never uploads that payload as Paths.bakName (srvbox_bak_v3.json) or otherwise records completion. Consequently, whenever the versioned file is still absent, every app startup repeats the legacy download and merge; if an old installation continues updating the legacy file, the new installation can repeatedly re-apply that history during startup, and a failed/unsupported legacy parse is retried forever. The claim would be false only if the superclass or Mergeable.merge implicitly uploads/creates the versioned remote file, but this method calls merge() only and the visible merge implementations mutate local stores, not remote storage. (lib/core/sync.dart) — inline-budget
• 🟡 Medium _remoteTooNew is never cleared on a new sync attempt that has no downloadable remote file, so one transient/newer-file refusal permanently disables uploads for the singleton. A concrete recovery path is: a v4 remote is read (line 55 sets the marker), the user removes/renames that remote file or switches to an empty backend, and retries sync; the base sync cycle can proceed directly to saveToFile/upload when no remote exists, but this override returns before super.backup because the stale marker is still non-null. The marker would only be safe if every SyncIface.sync attempt necessarily invokes fromFile before backup, including the missing-file/empty-backend path, or if another code path explicitly clears it. (lib/core/sync.dart) — inline-budget
• 🟡 Medium The Gist and WebDAV settings dialogs dispose their text controllers and focus nodes immediately after the dialog future returns, while the dialog route can still be animating out. showRoundDialog completes when the route is popped, not necessarily after its widget subtree has been removed; the Input widgets can therefore still hold/listen to these already-disposed objects during the exit transition, causing disposal/listener assertions or broken focus cleanup. The backup-password dialog in this same file explicitly avoids this lifecycle by putting both objects in DisposeWith, but these two dialogs do not. (lib/view/page/backup.dart) — inline-budget
• 🟡 Medium A manual WebDAV/Gist operation can write to a disposed notifier after the user leaves the page. Each handler awaits network, file, picker, and restore work, then its finally unconditionally assigns webdavLoading.value = false or gistLoading.value = false; if BackupPage is disposed during any await, dispose() has already disposed that notifier, so the completion callback can assert/throw instead of completing cleanly. The same operation also uses the old page context in its catch path to show an error after navigation. (lib/view/page/backup.dart) — anchor-unreliable
• 🟡 Medium The backup-password flow can call setState after BackupPage has been disposed. _onTapSetBakPwd awaits the password dialog and then an asynchronous secure-store write, but unconditionally executes setState(() {}); navigating away while either await is pending makes the completion throw setState() called after dispose. This is reachable both from the password row and from _ensureBakPwd, which is used by the remote auto/manual operations. (lib/view/page/backup.dart) — inline-budget
• 🟡 Medium Unknown push providers are treated as successful notifications. send_notification logs the unknown type and returns Ok, causing the caller to consume rate-limit quota even though no request was delivered and masking configuration errors. (monitor/src/monitoring/push.rs) — inline-budget
• 🟡 Medium Initial-admin bootstrap can be permanently wedged by a crash or transient failure between writing the credentials file and inserting the user. write_initial_credentials uses create_new, and the next startup retries the empty database but fails because initial-admin-credentials.txt already exists; the file is removed only on an insert error in the same invocation, not on a process crash after the write. (monitor/src/db/bootstrap.rs) — inline-budget
• 🟡 Medium Runtime configuration saves fail on Windows whenever config.toml already exists. (monitor/src/core/config_file.rs) — inline-budget
• 🟡 Medium Large idle-pause thresholds are interpreted as already idle because the u64 threshold is cast to i64. (monitor/src/monitoring/monitoring.rs) — inline-budget
• 🟡 Medium Network rules silently accept invalid matcher/provider values and evaluate the wrong metric. Only rx/in and tx/out select a direction; any other matcher—including the Go compatibility fixture's eth0-in—falls through to aggregate RX+TX, so an interface-specific or malformed rule can alert on unrelated traffic instead of being rejected or skipped. The compatibility test only checks that eth0-in survives config normalization and never evaluates it, so it does not catch the behavioral mismatch. This would be false only if all non-rx/tx network matchers are deliberately specified to mean aggregate traffic. (monitor/src/monitoring/rules.rs) — inline-budget
• 🟡 Medium The system-wide installation leaves the service's configuration directory and generated config.toml readable by every local user. /opt/server-box-monitor is created with the process umask (normally 0755), and the monitor creates config.toml with an ordinary fs::write (normally 0644); that TOML can contain push tokens/headers and other operator credentials, while the root service needs no reason to make them public. (monitor/install.sh) — anchor-unreliable
• 🟡 Medium A failed watch-token refresh can keep an old bearer credential in the new payload. buildPayload seeds tokens from the last application context, and the per-server catch only logs the issueWatchToken error; it does not remove tokens[id]. Thus, after the monitor password/JWT is changed or the token-issuing request fails, a previously issued 90-day watch token can continue to be delivered to (or remain on) the watch, including after a server is reselected, instead of being cleared. The watch token is independently accepted by /api/v1/status, /api/v1/metrics, and /api/v1/metrics/history, so this is an authentication persistence failure rather than merely a refresh UX issue. This would be disproved if every token-issuance failure were guaranteed to revoke the old database token and no stale token could remain in applicationContext; the shown server code does neither automatically. (lib/core/service/watch_sync.dart) — inline-budget
• 🟡 Medium The watch can send a monitor bearer token over remote plaintext HTTP, despite the phone-side monitor client rejecting non-loopback HTTP. MonitorClient.get constructs a URL from the payload without validating its scheme, and send attaches the Keychain token for every .monitor server; a selected server configured as http://10.0.0.5:3770 therefore transmits the scoped credential unencrypted. (ios/WatchApp/MonitorClient.swift) — inline-budget
• 🟡 Medium A failed token issuance can pair a changed endpoint with an old server token. buildPayload starts with tokens recovered from the current application context, catches issuance errors without removing tokens[id], and payloadFrom then emits that token for the newly read monitor.addr; after a server is moved to another agent or its old token is no longer valid there, the watch receives an entry that can never authenticate. (lib/core/service/watch_sync.dart) — inline-budget
• 🟡 Medium Deleting a server does not remove its pre-v2 Keychain credential. setServers computes stale accounts using tokenAccounts, which enumerates only keychainService; credentials stored under legacyPasswordService are never enumerated or deleted when the server disappears, and the cleanup call is therefore never made for them. (ios/WatchApp/Store.swift) — inline-budget
• 🟡 Medium A failed token issuance can put a stale token for a newly configured endpoint into the watch payload. buildPayload initializes tokens from the prior application context by server ID, then catches issueWatchToken errors without removing that entry; payloadFrom only checks that the token is nonempty. If a selected Spi keeps its ID but its monitor address changes to another agent (or issuance fails while the address/configuration change is being applied), the payload contains the new addr paired with the old agent's token, so the watch stores a server it cannot authenticate to. This is disproven only if server IDs are guaranteed never to be reused across monitor endpoints and monitor address changes cannot occur while token issuance fails. (lib/core/service/watch_sync.dart) — inline-budget
• 🟡 Medium The file listing leaks symlink targets outside the configured filesystem roots. list calls view_of for each directory entry, and view_of reads a symlink with read_link and returns exposed_path(&p) without resolving or redacting the target. Thus an authenticated caller with a root such as /srv/data can create or encounter /srv/data/secret-link -> /etc/shadow and receive /etc/shadow from /api/v1/fs/list, despite the API's confinement documentation saying it must not report anything about what lies outside the roots. This is an information-disclosure authorization regression even though following the link for read/stat is denied. The claim would be false if read_link targets were guaranteed by configuration to be within roots, or if the response intentionally allowed arbitrary target disclosure. (monitor/src/api/fs.rs) — inline-budget
• 🟡 Medium ProxyCommandSocket.done is tied to the child process exit rather than to EOF of the forwarded stdout stream. A ProxyCommand can exit while stdout still has buffered bytes (or can close stdout before its process exit future is delivered); dartssh2's socket lifecycle needs done to describe the transport stream completing, not merely the proxy process terminating. In that situation SSH transport teardown can race unread forwarded bytes, causing truncated handshakes/data or premature channel failure, and a process that exits successfully can make done complete even though the stream controller has not closed. This would be false only if dartssh2 never observes SSHSocket.done until after separately draining stream, or if the platform guarantees process exit is ordered after stdout EOF for every supported ProxyCommand. (lib/core/utils/proxy_command_socket.dart) — inline-budget
• 🟡 Medium Cancelling an inline (local/monitor) transfer is not guaranteed to prevent the final file from landing: runCopy checks cancelled while producing source chunks, but once the last chunk has passed that check it awaits dest.write with no cancellation mechanism or post-write check. If dispose() occurs during that write/rename window, the status is removed and marked disposed while the backend can still atomically rename the complete file into the destination. This is false only if every backend's write synchronously observes the external status (the interface provides no such contract). (lib/data/model/file/copy_tree.dart) — inline-budget
• 🟡 Medium A filesystem upload can be replayed after a 401 even though its request body is a one-shot stream, causing the retry to fail or submit an empty/partial body and leaving the caller unable to distinguish token recovery from upload failure. (lib/data/provider/server/monitor_http.dart) — inline-budget
• 🟡 Medium fsWrite can still replay a one-shot upload stream after a 401, despite the pre-login step. If the token expires (or is invalidated) after the initial _login() but before/during the PUT, _authed catches 401, clears the token, logs in, and invokes fn() again; fn reuses the same data stream. A File.openRead()/single-subscription stream then throws on the second listen (or uploads no data), so a write fails or violates the atomic-write expectation instead of reporting a clean auth failure. (lib/data/provider/server/monitor_http.dart) — anchor-unreliable
• 🟡 Medium Server names can be displayed for the wrong agent after editing a server URL or logging out. serverNames leaves byServer[id] untouched when the token disappears or the URL changes, and its refresh catches failures while deliberately retaining the previous value. The same ID therefore continues to show agent A's name for agent B (or for an unauthenticated/unreachable entry) until B successfully responds, and permanently if it never does. (monitor/frontend/src/lib/serverNames.svelte.ts) — anchor-unreliable
• 🟡 Medium A late 401 from the previously selected server can log out the newly selected server. request() captures the old server URL/token for fetch, but on any 401 calls servers.logout(), which operates on servers.current at response time. When Dashboard switches from A to B, an A request that races with Poller.stop() can therefore clear B's session and cause an unrelated redirect to login. (monitor/frontend/src/lib/api.ts) — anchor-unreliable
• 🔵 Low The migration-upgrade integration test does not test migration 007 (or any real upgrade from a legacy schema): it first runs the full current migrator, which creates and marks 007 applied, then deletes only migration 006 and invokes the same full migrator. The second run therefore skips both the already-applied 007 and the rest of the current set, so a broken 007 application against an existing populated database would pass this test. This leaves the required existing-database migration behavior unverified; it would be disproven if another test constructs a pre-007 database and applies 007, but no such test is present in the inspected test set.

• Token rotation occurs before the durable watch-context update, so a transient updateApplicationContext failure revokes the credential currently stored on the watch. Each build issues a new token for watch:<id>, and the monitor's upsert replaces the old hash; if the subsequent context update throws, the watch still has the old token while the server accepts only the new one. The watch is then offline until a later successful push, and if no later push occurs it remains broken. This would be false only if updateApplicationContext is atomic with the monitor token issuance or the monitor retains old token generations, neither of which is present here. (lib/core/service/watch_sync.dart)
• An in-flight card-order load can apply the wrong server's order after the user switches servers. loadCardOrder() awaits api.getCardOrder() and assigns cardOrder without capturing the server identity or cancellation; the effect starts it whenever authenticated, but has no cleanup/generation guard. If server A's slow response returns after selecting B, A's order is rendered for B (and a later drag can persist that order to B). (monitor/frontend/src/pages/Dashboard.svelte)

## Additional findings on this change (not posted inline) (73)

In monitor/src/api/fs.rs, address this finding:
Removing a symlink removes its canonical target rather than the symlink entry itself, contrary to the endpoint's documented remove semantics; a link inside one configured root can therefore delete a file or directory in another configured root.

In monitor/src/api/fs.rs, address this finding:
`DELETE /api/v1/fs/remove` can delete the target of an in-root symlink instead of deleting the symlink itself. `remove` calls `resolve_existing`, which canonicalizes every symlink, and then calls `symlink_metadata`/`remove_dir_all` on that canonical target; for `/srv/root/link -> /srv/root/important`, a request for `/srv/root/link` becomes `/srv/root/important` and removes the target. This violates the handler's stated “a link is deleted, never followed” invariant and can turn a harmless shortcut deletion into destructive deletion of another in-root tree. The claim would be false if `resolve_existing` preserved the final directory entry (or if the target could not be removed by the resulting operation).

In monitor/frontend/src/lib/api.ts around line 66, address this finding:
A late 401 from a previously selected server can log out the newly selected server. If a poll/request for A is in flight and the user switches to B before A responds, `request()` receives A's 401 but calls `servers.logout()`, whose implementation clears `servers.current` (now B), thereby deleting B's valid token and sessionStorage entry.

In lib/core/utils/server.dart around line 197, address this finding:
A successful jump connection leaks the jump SSHClient and leaves it owning the forwarding transport with no lifecycle owner: the local variable is only closed in the catch path, while the successful path returns the forward channel and discards jumpClient. When the target client is later closed or the connection is disposed, there is no retained jump client to close, so the jump SSH session/socket can remain alive indefinitely.

In lib/data/provider/pve.dart around line 325, address this finding:
TFA submission is not bound to the session generation that produced its challenge. submitTfaCode captures only _pendingTfaChallenge, then after awaits calls _loginWithTfaChallenge and performs _getRelease/list with only ref.mounted checks. If the user reconnects after the challenge dialog opens, the captured old challenge is sent through the replacement session and the result can set current state/auth headers or close/publish errors for the new generation.

In lib/data/model/file/transfer_worker.dart around line 479, address this finding:
Specialized SFTP staging names are not unique across concurrent transfer isolates, so one transfer can overwrite or delete another transfer's in-progress staging file.

In lib/data/model/file/transfer_worker.dart around line 422, address this finding:
A download idle timeout races the still-running SFTP read: Future.any returns on the timeout, then the finally block closes the local file and later the SFTP resources while downloadFuture is not cancelled or awaited. The outstanding read can write to a closed file, produce unhandled errors, or continue consuming resources after the transfer has reported failure.

In lib/data/model/file/transfer_worker.dart around line 507, address this finding:
The SFTP replacement fallback deletes the existing destination after any failed rename for which stat(path) succeeds, without establishing that the failure was caused by an existing destination. A permission, transport, or server-side rename failure can therefore turn a failed transfer into loss of the previously good destination, and the second rename can fail leaving neither file.

In lib/data/provider/server/monitor_http.dart around line 362, address this finding:
The monitor backend treats `FileBackend.write`'s optional `size` hint as an authoritative HTTP Content-Length. `runCopy` passes a listing/stat-derived size, but the interface explicitly says that value is only a hint and the source can change while it is being read. If the actual stream length differs, the agent's HTTP payload framing can terminate early or wait/fail instead of consuming the stream, so a valid copy can be rejected or committed with a truncated body; the monitor implementation does not validate the byte count before renaming.

In lib/data/model/file/transfer_worker.dart around line 477, address this finding:
Concurrent transfers to the same destination can reuse the same staging pathname and corrupt or delete each other's work.

In lib/core/sync.dart around line 28, address this finding:
The newer-schema refusal is not scoped to the sync attempt and can be bypassed by an overlapping sync, allowing an older copy to overwrite a newer remote file. `fromFile` clears the singleton marker at the start of every read, while `backup` later consults the shared marker; for example, sync A reads a too-new remote and yields after setting `_remoteTooNew`, sync B starts/reads any ordinary remote and clears it, then A reaches `backup` and uploads. The same singleton is used by automatic sync callers, so this is not limited to a UI double-tap. This is introduced by the static marker-based refusal design; it would be false only if `SyncIface.sync` serialized all calls globally and no other `fromFile` could run before the first call's backup decision.

In monitor/install.sh around line 235, address this finding:
Upgrading from a malformed or incomplete package can permanently remove the working frontend and migrations and still report success. `SBM_INSTALL_PKG` is accepted after checking only the binary, while `install_files` deletes the existing `frontend` and `migrations` before copying those package paths; because the script does not use `set -e` or check the `cp` results, missing paths leave the service running without its panel/migrations and `upgrade` prints success.

In ios/WatchApp/PhoneConnMgr.swift around line 35, address this finding:
An explicitly empty current configuration is resurrected from the legacy `ctx` on every watch process launch. `PhoneConnMgr.init` runs `migrateLegacyCtx()` whenever the decoded server list is empty, but migration never removes `ctx` or records that migration was attempted. Thus after the phone sends an empty `servers`/`urls` payload (user cleared all watch servers), the next `PhoneConnMgr` initialization repopulates the old URLs and displays servers the user removed. This would be false only if some other code deletes `UserDefaults.standard["ctx"]` or writes a persistent migration marker when the empty payload is applied; no such code is present in the reviewed implementation.

In monitor/frontend/src/components/LoginForm.svelte around line 18, address this finding:
A login response can be stored on the wrong server entry if the user changes the selected server while the request is in flight. `api.login()` reads `servers.current` when constructing the request, but `LoginForm` calls `servers.login()` after await, and `login()` uses the then-current `currentId`; logging into A followed by selecting B before the response stores A's token on B and leaves A unauthenticated.

In lib/core/utils/server.dart around line 528, address this finding:
Forgetting a host key can be undone by an already queued acceptance write. persistHostKeyFingerprint serializes writes through _hostKeyPersistence, but forgetHostKeyFingerprints reads the store and calls prop.put directly outside that queue. If an accepted key write is queued, the user forgets the server before it runs, and then the queued callback executes, it writes the accepted key back after the forget operation, so the next connection silently trusts it again.

In lib/data/provider/pve.dart around line 456, address this finding:
A stale `list()` request can tear down a newer PVE session during reconnect. `list` has no generation/session identity, so if its request from generation N fails after `reconnect()` has incremented `_sessionGeneration` and installed generation N+1, the connection-failure branch unconditionally calls `_closeSession`; that closes the current Dio, ServerSocket, and forwards for N+1 and leaves the new init disconnected. This is proven false only if callers can guarantee no list request survives a reconnect (including the init-triggered list and timer/UI calls).

In monitor/install.sh around line 242, address this finding:
The installer preserves an existing `.env` without repairing its permissions. An existing world-readable `.env` (for example from a legacy install or a manual copy) remains readable by all local users, while it may contain JWT_SECRET and push credentials; `chmod 600` is performed only in the newly-created-file branch.

In lib/data/provider/pve.dart, address this finding:
A stale Proxmox list request can tear down a replacement session. list() does not capture or validate _sessionGeneration; on a connection failure it unconditionally calls _closeSession. If reconnect() or a provider client replacement has already created a new forwarding/session generation while the old cluster/resources request is still pending, the old request's failure enters this branch and closes the new Dio session, server socket, and forwards, then publishes disconnected state for the current connection.

In lib/core/utils/sftp_file_backend.dart, address this finding:
SFTP overwrite can permanently delete the good destination when the replacement rename fails after the fallback removal. `_replace` removes `path` and then performs a second rename without restoring or retaining the old file; any permission, quota, disconnect, or other error on that second rename leaves neither the old destination nor the new file. This violates `FileBackend.write`'s atomic replacement/integrity contract for servers without the POSIX rename extension.

In lib/data/provider/server/single.dart, address this finding:
Browser TOFU is raceable across simultaneous connections that start with separate cache snapshots. `genClient` copies the global store into `hostKeyCache` before constructing each verifier; two connections that see no pin can both prompt, and if they receive different offered keys, `promptHostKeyExclusively` merely serializes the dialogs rather than re-reading or atomically claiming the pin. Each verifier then writes its own key and returns true, while the serialized persistence queue eventually leaves whichever key was persisted last. Thus both a legitimate key and a concurrent impostor can be accepted during first use, and the second prompt is shown as `isMismatch: false` instead of comparing against the first winner. This would be proven false only if all concurrent `genClient` calls are guaranteed to share one mutable cache or the underlying SSH callback cannot concurrently offer different keys.

In monitor/src/db/cleanup.rs around line 17, address this finding:
Expired watch-token rows are never cleaned up. Migration 007 adds an expiry index, and verification excludes rows with `expires_at <= now`, but the only scheduled cleanup calls metrics, alerts, policy tables, and size-capped time-series cleanup; it never deletes from `watch_tokens`. An authenticated caller can issue tokens for an unbounded series of distinct client IDs, leaving one row per client permanently after the 90-day expiry and growing the database/index indefinitely. This violates the data-integrity/cleanup obligation; it would be false if another startup or cleanup path not present here deletes expired watch_tokens.

In monitor/src/db/database.rs around line 15, address this finding:
A database upgraded with migration 007 cannot be opened by a downgraded binary whose embedded migrations stop at 006. `db::database::init` always runs the embedded SQLx migrator, while SQLx migration execution has no downgrade path and the older migrator has no migration 007 to reconcile the `_sqlx_migrations` row. On rollback of the monitor binary, startup therefore fails before the server is usable, violating the stated downgrade/compatibility expectation. This would be disproven if the supported downgrade procedure explicitly removes/reverts migration 007 or the older binary embeds a compatible migration history.

In lib/core/service/watch_sync.dart around line 132, address this finding:
Token rotation can revoke the watch's currently working credential before the new payload is durably delivered. Each push issues a new token first; the backend upserts `(subject, client_id)`, replacing the old hash, and only afterward does `_pushOnce` call `updateApplicationContext`. If context delivery fails (unpaired/transient WatchConnectivity error), the watch still has the old token but the agent has already invalidated it, causing an outage until a later successful push.

In lib/core/service/watch_sync.dart around line 222, address this finding:
Legacy URL migration can be permanently skipped when the first launch has no old application context. `_importLegacyUrls` sets `watchLegacyUrlsImported` to true whenever `urls` is null or empty, so a launch racing activation/context delivery (or a pre-v2 install with context not yet available) will never retry and the old URLs are lost.

In ios/WatchApp/PhoneConnMgr.swift around line 150, address this finding:
Malformed/duplicate server IDs are accepted into the watch list, producing duplicate SwiftUI identities and ambiguous token ownership. `PhoneConnMgr.parse` validates nonempty IDs but never rejects a repeated ID, while `WatchSync.payloadFrom` likewise emits one entry per repeated selected ID; `ContentView` renders `ForEach(..., id: \.element.id)`, so duplicate entries violate the identity invariant and the token dictionary's last duplicate silently wins.

In ios/WatchApp/MonitorClient.swift around line 45, address this finding:
Replacing/removing a server leaves its URLSession (and therefore its MonitorClient and connection pool) permanently retained, leaking resources over time.

In ios/WatchApp/Store.swift around line 46, address this finding:
Legacy keychain credentials are not fully cleaned when a server is removed. `setServers` enumerates only accounts under the new `keychainService`; it calls `setToken(nil, for:)` only for those accounts absent from the live server IDs. Credentials left under `legacyPasswordService` are never enumerated, so an old-build token for a removed server survives indefinitely (and the cleanup in `setToken` is never reached for that ID). This would be false only if the old service is guaranteed to contain no accounts on upgrade or another migration enumerates and deletes that service; the reviewed Store has no such enumeration or cleanup.

In ios/WatchApp/PhoneConnMgr.swift around line 145, address this finding:
The watch accepts duplicate server IDs and passes them to a SwiftUI `ForEach` whose identity is the server ID, producing non-unique page identities and potentially rendering/loading the wrong page. `parse` appends every valid entry without tracking IDs, while `ContentView` uses `id: \.element.id`; a malformed/retried payload or duplicated persisted selection can therefore create two entries with the same identity, and token/snapshot storage also collapses them by ID. This would be false only if WatchConnectivity/payload producers enforce uniqueness for all future payloads; the parser itself has no such invariant check and the persisted selection is not validated here.

In monitor/frontend/src/lib/agentUrl.ts around line 14, address this finding:
The frontend accepts HTTPS/loopback URLs containing a query or fragment, then appends the API path after that delimiter, so requests are sent to the wrong URL rather than the configured server API.

In monitor/frontend/src/lib/api.ts around line 50, address this finding:
A late 401 from an explicit request for server A can log out whichever server is currently selected, including server B, because the generic request helper logs out through mutable global selection rather than the server whose token was used.

In monitor/frontend/src/lib/api.ts around line 87, address this finding:
Explicit-server capability and name probes do not invalidate the probed server's session on 401, so a revoked/expired non-selected token remains stored in sessionStorage and is repeatedly treated as authenticated.

In lib/data/provider/server/monitor_http.dart around line 474, address this finding:
Each monitor WebSocket upgrade allocates a fresh HttpClient and discards it without closing it, so repeated terminal/tunnel reconnects leak client/socket-pool resources until process shutdown.

In monitor/frontend/src/pages/Dashboard.svelte around line 88, address this finding:
Rapid card reorders can be persisted out of order. `onCardDrop` fires `api.updateCardOrder(cardOrder)` without awaiting or serializing the previous write; if the first PUT is delayed and the second arrives first, the first stale order can arrive last and become the server's final order, so a reload/other client loses the user's latest arrangement.

In lib/core/utils/server.dart around line 737, address this finding:
ensureKnownHostKey treats any cached key type as sufficient and can skip verification of the negotiated algorithm. _hasKnownHostFingerprintForSpi only checks for an identity prefix, so a stored ssh-ed25519 key causes ensureKnownHostKey to return before connecting even when the server/client will negotiate ssh-rsa (or another type) whose fingerprint has never been trusted. This violates exact identity-plus-key-type trust and can make the preflight report success without verifying the key type actually used.

In lib/core/utils/server.dart around line 719, address this finding:
`ensureKnownHostKey` treats any remembered key for a server as sufficient, even when it is for a different SSH host-key algorithm. This contradicts the per-key-type trust contract: a server with only `srv::ssh-ed25519` remembered can offer RSA and the preflight returns without opening/verifying it, so callers relying on this preflight do not get the required prompt for the negotiated key.

In lib/core/utils/server.dart around line 702, address this finding:
`ensureKnownHostKey` does not honor jump-server failover while recursively preflighting unknown jump hosts: it awaits the first unresolved candidate and propagates its error instead of trying the next candidate. With jump candidates `[unreachable A, reachable B]` and neither fingerprint cached, preflight fails before `genClient` can apply its failover loop, so a valid fallback path is rejected.

In lib/core/utils/server.dart around line 502, address this finding:
Forgetting a host key can be undone by an already queued acceptance write. `persistHostKeyFingerprint` serializes writes in `_hostKeyPersistence`, but `forgetHostKey`/`forgetHostKeyFingerprints` directly read and `put` the store without joining that queue. If a user accepts a key (or a queued normalization write is pending) and immediately deletes it from Known Hosts, the forget operation can complete first; the queued persistence then rereads the store and re-adds the accepted fingerprint. The UI reports the key as forgotten, but the next connection is silently trusted. This would be disproven only if the store guarantees these `put` operations are ordered behind the asynchronous `prop.set` queue, which this code does not await or connect to.

In lib/data/model/file/transfer_worker.dart around line 685, address this finding:
Unknown or stale source sizes can produce progress above 100% in the generic copy path. planCopy makes totalBytes a lower bound and runCopy counts actual bytes, but _copy computes percent as transferred / total * 100 whenever total > 0 with no cap; a tree containing a known-size file plus an unknown-size or underreported file can report 150% (or more), violating the stated lower-bound progress contract and misleading completion UI.

In lib/data/model/file/transfer_worker.dart around line 567, address this finding:
SFTP uploads never publish their remote staging path, so cancellation/disposal cannot record or clean the staged file. _upload assigns staging and writes it, but unlike _download and generic _copy it sends no TransferStaging event; if the worker is disposed or its isolate is killed during upload, the remote .sb-part file remains indefinitely and is invisible to the cancellation cleanup path.

In lib/core/utils/local_file_backend.dart around line 120, address this finding:
The local staged write cannot replace an existing destination on Windows. `File.rename` is used directly for the final commit, but Dart's Windows rename fails when the target already exists; consequently copying/overwriting an existing local file reports failure after successfully writing the staging file, instead of honoring `write`'s documented 'replacing whatever was there' behavior. The same path works on Unix, making this a platform-specific integrity/functional regression in the new staging implementation.

In lib/data/model/file/transfer_worker.dart around line 503, address this finding:
A failed upload rename can delete an existing good destination even when the rename failed for permission, connection, or another non-collision reason.

In lib/core/sync.dart around line 111, address this finding:
A successful later sync can remain permanently blocked by a stale newer-schema marker when the intervening attempt fails before `fromFile` runs. `fromFile` is the only place that clears `_remoteTooNew`, but `backup` returns immediately whenever the static marker is non-null; thus a too-new read followed by a remote list/download failure (or another sync path that never calls `fromFile`) leaves the marker set, and subsequent valid syncs silently skip upload until some read happens to clear it. The UI has no reset for this state, so recovery is not reliable. This would be false only if the superclass guarantees every failed sync always invokes `fromFile` before any future backup call, including list/download failures.

In lib/view/page/backup.dart, address this finding:
Automatic WebDAV and Gist syncs can leave their loading controls stuck forever after a recoverable sync error. Each validator sets its notifier to true, awaits `bakSync.sync`, and only then sets it false; there is no `try/finally`. A download/auth/upload exception therefore propagates out of the validator while `webdavLoading` or `gistLoading` remains true, so the manual controls continue rendering `SizedLoading.small` and the user has no retry control from that page. This would be false only if `SyncIface.sync` is guaranteed never to throw for any remote failure (contradicted by the surrounding manual handlers' error handling).

In lib/view/page/backup.dart around line 47, address this finding:
Pending automatic or manual remote work can write to a disposed loading notifier after the BackupPage is removed. `dispose` immediately calls `webdavLoading.dispose()` and `gistLoading.dispose()`, but the automatic validators and manual handlers assign `.value = false` after awaits without checking `mounted`; navigating away while `bakSync.sync`, a list/download, or an upload is pending can therefore trigger a disposed-notifier exception during completion (and the async validator may also return into a disposed StoreSwitch). This would be false only if the notifier implementation permits writes after `dispose` and all remote operations are synchronously cancelled on route disposal.

In lib/view/page/backup.dart around line 274, address this finding:
The new `remoteTooNew` state is never surfaced by the backup page, and the automatic switch is reported as successfully enabled even when upload was refused. `BakSyncer.backup` only logs and returns on a too-new remote, while each validator awaits `bakSync.sync` and then returns `true`; `BackupPage` contains no read of `BakSyncer.remoteTooNew` or error/toast path. Consequently an older device can show the provider enabled and stop retrying while the remote remains untouched, with no explanation to the user. This would be false only if `SyncIface.sync` independently inspects this static getter and presents a UI error, but no such integration exists in the changed page/code search.

In lib/view/page/backup.dart, address this finding:
The provider-conflict checks are raceable, so two concurrent enable operations can both pass and enable conflicting backends. Each StoreSwitch validator reads the other preference before its asynchronous password dialog/sync; if WebDAV and Gist (or iCloud and WebDAV) are enabled nearly simultaneously, both can observe the other as false, then both return true and persist their own switch. Later automatic callers use `remoteStorage`, which silently chooses iCloud over WebDAV over Gist, while the user may believe both are active and different in-flight syncs can target different providers. This would be false only if StoreSwitch serializes validators globally or preference writes are transactionally mutually exclusive, neither established by this page.

In lib/view/page/backup.dart, address this finding:
Backup-page async operations can write to disposed loading notifiers after the page is removed. Each WebDAV/Gist handler sets `webdavLoading` or `gistLoading` in `finally`, while `dispose()` disposes that notifier; navigating away while a list/download/upload is pending therefore causes a post-dispose notifier write (and can surface an exception rather than merely cancelling the operation).

In lib/core/sync.dart around line 71, address this finding:
A failed encrypted remote read can still allow sync to overwrite the remote backup. `fromFile` catches every non-schema error (including a wrong, missing, or stale backup password while parsing a Cryptor-encrypted payload), then retries without a password; that retry also fails, but `_remoteTooNew` remains null. `SyncIface`'s documented behavior is to upload after a merge/read failure, and `backup()` only blocks when `_remoteTooNew` is set, so the local copy can replace an unreadable encrypted remote instead of preserving it.

In lib/core/sync.dart around line 145, address this finding:
`inheritLegacyRemote` does not perform the operation its own comment promises: after downloading and merging `srvbox_bak.json`, it never uploads that payload as `Paths.bakName` (`srvbox_bak_v3.json`) or otherwise records completion. Consequently, whenever the versioned file is still absent, every app startup repeats the legacy download and merge; if an old installation continues updating the legacy file, the new installation can repeatedly re-apply that history during startup, and a failed/unsupported legacy parse is retried forever. The claim would be false only if the superclass or `Mergeable.merge` implicitly uploads/creates the versioned remote file, but this method calls `merge()` only and the visible merge implementations mutate local stores, not remote storage.

In lib/core/sync.dart around line 110, address this finding:
`_remoteTooNew` is never cleared on a new sync attempt that has no downloadable remote file, so one transient/newer-file refusal permanently disables uploads for the singleton. A concrete recovery path is: a v4 remote is read (line 55 sets the marker), the user removes/renames that remote file or switches to an empty backend, and retries sync; the base sync cycle can proceed directly to `saveToFile`/upload when no remote exists, but this override returns before `super.backup` because the stale marker is still non-null. The marker would only be safe if every `SyncIface.sync` attempt necessarily invokes `fromFile` before `backup`, including the missing-file/empty-backend path, or if another code path explicitly clears it.

In lib/view/page/backup.dart around line 739, address this finding:
The Gist and WebDAV settings dialogs dispose their text controllers and focus nodes immediately after the dialog future returns, while the dialog route can still be animating out. `showRoundDialog` completes when the route is popped, not necessarily after its widget subtree has been removed; the `Input` widgets can therefore still hold/listen to these already-disposed objects during the exit transition, causing disposal/listener assertions or broken focus cleanup. The backup-password dialog in this same file explicitly avoids this lifecycle by putting both objects in `DisposeWith`, but these two dialogs do not.

In lib/view/page/backup.dart, address this finding:
A manual WebDAV/Gist operation can write to a disposed notifier after the user leaves the page. Each handler awaits network, file, picker, and restore work, then its `finally` unconditionally assigns `webdavLoading.value = false` or `gistLoading.value = false`; if BackupPage is disposed during any await, `dispose()` has already disposed that notifier, so the completion callback can assert/throw instead of completing cleanly. The same operation also uses the old page context in its catch path to show an error after navigation.

In lib/view/page/backup.dart around line 157, address this finding:
The backup-password flow can call `setState` after BackupPage has been disposed. `_onTapSetBakPwd` awaits the password dialog and then an asynchronous secure-store write, but unconditionally executes `setState(() {})`; navigating away while either await is pending makes the completion throw `setState() called after dispose`. This is reachable both from the password row and from `_ensureBakPwd`, which is used by the remote auto/manual operations.

In monitor/src/monitoring/push.rs around line 105, address this finding:
Unknown push providers are treated as successful notifications. `send_notification` logs the unknown type and returns Ok, causing the caller to consume rate-limit quota even though no request was delivered and masking configuration errors.

In monitor/src/db/bootstrap.rs around line 16, address this finding:
Initial-admin bootstrap can be permanently wedged by a crash or transient failure between writing the credentials file and inserting the user. `write_initial_credentials` uses `create_new`, and the next startup retries the empty database but fails because `initial-admin-credentials.txt` already exists; the file is removed only on an insert error in the same invocation, not on a process crash after the write.

In monitor/src/core/config_file.rs around line 133, address this finding:
Runtime configuration saves fail on Windows whenever config.toml already exists.

In monitor/src/monitoring/monitoring.rs around line 227, address this finding:
Large idle-pause thresholds are interpreted as already idle because the u64 threshold is cast to i64.

In monitor/src/monitoring/rules.rs around line 200, address this finding:
Network rules silently accept invalid matcher/provider values and evaluate the wrong metric. Only `rx`/`in` and `tx`/`out` select a direction; any other matcher—including the Go compatibility fixture's `eth0-in`—falls through to aggregate RX+TX, so an interface-specific or malformed rule can alert on unrelated traffic instead of being rejected or skipped. The compatibility test only checks that `eth0-in` survives config normalization and never evaluates it, so it does not catch the behavioral mismatch. This would be false only if all non-rx/tx network matchers are deliberately specified to mean aggregate traffic.

In monitor/install.sh, address this finding:
The system-wide installation leaves the service's configuration directory and generated `config.toml` readable by every local user. `/opt/server-box-monitor` is created with the process umask (normally 0755), and the monitor creates `config.toml` with an ordinary `fs::write` (normally 0644); that TOML can contain push tokens/headers and other operator credentials, while the root service needs no reason to make them public.

In lib/core/service/watch_sync.dart around line 125, address this finding:
A failed watch-token refresh can keep an old bearer credential in the new payload. `buildPayload` seeds `tokens` from the last application context, and the per-server catch only logs the `issueWatchToken` error; it does not remove `tokens[id]`. Thus, after the monitor password/JWT is changed or the token-issuing request fails, a previously issued 90-day watch token can continue to be delivered to (or remain on) the watch, including after a server is reselected, instead of being cleared. The watch token is independently accepted by `/api/v1/status`, `/api/v1/metrics`, and `/api/v1/metrics/history`, so this is an authentication persistence failure rather than merely a refresh UX issue. This would be disproved if every token-issuance failure were guaranteed to revoke the old database token and no stale token could remain in `applicationContext`; the shown server code does neither automatically.

In ios/WatchApp/MonitorClient.swift around line 126, address this finding:
The watch can send a monitor bearer token over remote plaintext HTTP, despite the phone-side monitor client rejecting non-loopback HTTP. `MonitorClient.get` constructs a URL from the payload without validating its scheme, and `send` attaches the Keychain token for every `.monitor` server; a selected server configured as `http://10.0.0.5:3770` therefore transmits the scoped credential unencrypted.

In lib/core/service/watch_sync.dart around line 134, address this finding:
A failed token issuance can pair a changed endpoint with an old server token. `buildPayload` starts with tokens recovered from the current application context, catches issuance errors without removing `tokens[id]`, and payloadFrom then emits that token for the newly read `monitor.addr`; after a server is moved to another agent or its old token is no longer valid there, the watch receives an entry that can never authenticate.

In ios/WatchApp/Store.swift around line 126, address this finding:
Deleting a server does not remove its pre-v2 Keychain credential. `setServers` computes stale accounts using `tokenAccounts`, which enumerates only `keychainService`; credentials stored under `legacyPasswordService` are never enumerated or deleted when the server disappears, and the cleanup call is therefore never made for them.

In lib/core/service/watch_sync.dart around line 133, address this finding:
A failed token issuance can put a stale token for a newly configured endpoint into the watch payload. `buildPayload` initializes `tokens` from the prior application context by server ID, then catches `issueWatchToken` errors without removing that entry; `payloadFrom` only checks that the token is nonempty. If a selected Spi keeps its ID but its monitor address changes to another agent (or issuance fails while the address/configuration change is being applied), the payload contains the new `addr` paired with the old agent's token, so the watch stores a server it cannot authenticate to. This is disproven only if server IDs are guaranteed never to be reused across monitor endpoints and monitor address changes cannot occur while token issuance fails.

In monitor/src/api/fs.rs around line 515, address this finding:
The file listing leaks symlink targets outside the configured filesystem roots. `list` calls `view_of` for each directory entry, and `view_of` reads a symlink with `read_link` and returns `exposed_path(&p)` without resolving or redacting the target. Thus an authenticated caller with a root such as `/srv/data` can create or encounter `/srv/data/secret-link -> /etc/shadow` and receive `/etc/shadow` from `/api/v1/fs/list`, despite the API's confinement documentation saying it must not report anything about what lies outside the roots. This is an information-disclosure authorization regression even though following the link for read/stat is denied. The claim would be false if `read_link` targets were guaranteed by configuration to be within roots, or if the response intentionally allowed arbitrary target disclosure.

In lib/core/utils/proxy_command_socket.dart around line 142, address this finding:
`ProxyCommandSocket.done` is tied to the child process exit rather than to EOF of the forwarded stdout stream. A ProxyCommand can exit while stdout still has buffered bytes (or can close stdout before its process exit future is delivered); dartssh2's socket lifecycle needs `done` to describe the transport stream completing, not merely the proxy process terminating. In that situation SSH transport teardown can race unread forwarded bytes, causing truncated handshakes/data or premature channel failure, and a process that exits successfully can make `done` complete even though the stream controller has not closed. This would be false only if dartssh2 never observes `SSHSocket.done` until after separately draining `stream`, or if the platform guarantees process exit is ordered after stdout EOF for every supported ProxyCommand.

In lib/data/model/file/copy_tree.dart around line 148, address this finding:
Cancelling an inline (local/monitor) transfer is not guaranteed to prevent the final file from landing: `runCopy` checks `cancelled` while producing source chunks, but once the last chunk has passed that check it awaits `dest.write` with no cancellation mechanism or post-write check. If `dispose()` occurs during that write/rename window, the status is removed and marked disposed while the backend can still atomically rename the complete file into the destination. This is false only if every backend's `write` synchronously observes the external status (the interface provides no such contract).

In lib/data/provider/server/monitor_http.dart around line 164, address this finding:
A filesystem upload can be replayed after a 401 even though its request body is a one-shot stream, causing the retry to fail or submit an empty/partial body and leaving the caller unable to distinguish token recovery from upload failure.

In lib/data/provider/server/monitor_http.dart, address this finding:
`fsWrite` can still replay a one-shot upload stream after a 401, despite the pre-login step. If the token expires (or is invalidated) after the initial `_login()` but before/during the PUT, `_authed` catches 401, clears the token, logs in, and invokes `fn()` again; `fn` reuses the same `data` stream. A `File.openRead()`/single-subscription stream then throws on the second listen (or uploads no data), so a write fails or violates the atomic-write expectation instead of reporting a clean auth failure.

In monitor/frontend/src/lib/serverNames.svelte.ts, address this finding:
Server names can be displayed for the wrong agent after editing a server URL or logging out. `serverNames` leaves `byServer[id]` untouched when the token disappears or the URL changes, and its refresh catches failures while deliberately retaining the previous value. The same ID therefore continues to show agent A's name for agent B (or for an unauthenticated/unreachable entry) until B successfully responds, and permanently if it never does.

In monitor/frontend/src/lib/api.ts, address this finding:
A late 401 from the previously selected server can log out the newly selected server. `request()` captures the old server URL/token for fetch, but on any 401 calls `servers.logout()`, which operates on `servers.current` at response time. When Dashboard switches from A to B, an A request that races with Poller.stop() can therefore clear B's session and cause an unrelated redirect to login.

In monitor/tests/migration_upgrade.rs, address this finding:
The migration-upgrade integration test does not test migration 007 (or any real upgrade from a legacy schema): it first runs the full current migrator, which creates and marks 007 applied, then deletes only migration 006 and invokes the same full migrator. The second run therefore skips both the already-applied 007 and the rest of the current set, so a broken 007 application against an existing populated database would pass this test. This leaves the required existing-database migration behavior unverified; it would be disproven if another test constructs a pre-007 database and applies 007, but no such test is present in the inspected test set.

Serialize asynchronous stream event handling.

Stream.listen does not await _handleEvent. Later events can update state while _persist() is pending, and persistence errors can bypass onError. Use asyncMap before listen and set cancelOnError: true.

Isolate the missing-token condition in this test.

payload() passes the tokens map directly to WatchSync.payloadFrom; it does not issue a token. This case omits the token and also sets user and pwd to empty strings, so the assertion can pass for either condition. Keep valid legacy credentials and omit only tokens, or test the token-issuance caller separately.

🔎 Confirmed findings (5)

• 🟠 High The watch sends bearer watch tokens to any URL in its stored/pushed WatchServer, without enforcing HTTPS or loopback HTTP. get constructs a URL and sets Authorization before send, and loadLegacy also accepts arbitrary URLs (though legacy is unauthenticated). A malicious/corrupt WatchConnectivity payload or stale insecure monitor configuration can therefore leak the scoped token over plaintext HTTP. (inline)
• 🟠 High Watch tokens are reused without considering their server-issued expiry, so a watch that remains configured for more than 90 days never receives a replacement token and stays unauthorized indefinitely. (inline)
• 🟠 High A bulk server import can overwrite existing servers and leave the live provider/order state stale. (inline)
• 🟠 High Saving a new private key with an existing name overwrites the existing key without a conflict check, while the notifier appends a second in-memory entry. The editor constructs PrivateKeyInfo(id: name, ...) and calls add; the store key is id, so put replaces the old PEM, and PrivateKeyNotifier.add builds [..., info] rather than rejecting the duplicate. Servers referring to that key ID therefore start using a different private key, and the key UI can show duplicate rows. (inline)
• 🟠 High Renaming a private key to the ID of another existing key can delete/replace the wrong identity. PrivateKeyNotifier.update delegates to CachedHiveStore.update, which writes the new ID (overwriting any key already stored there) and then removes the old ID; the editor allows any non-empty name and performs no collision check. A rename from A to B therefore destroys B's key and leaves servers referencing B with the renamed A material. (inline)

⛔ Unresolved from previous review (14) — not approved until fixed

• Browser TOFU is raceable across simultaneous connections that start with separate cache snapshots. genClient copies the global store into hostKeyCache before constructing each verifier; two connections that see no pin can both prompt, and if they receive different offered keys, promptHostKeyExclusively merely serializes the dialogs rather than re-reading or atomically claiming the pin. Each verifier then writes its own key and returns true, while the serialized persistence queue eventually leaves whichever key was persisted last. Thus both a legitimate key and a concurrent impostor can be accepted during first use, and the second prompt is shown as isMismatch: false instead of comparing against the first winner. This would be proven false only if all concurrent genClient calls are guaranteed to share one mutable cache or the underlying SSH callback cannot concurrently offer different keys. — The defect is still reachable: genClient still creates a private snapshot with Map<String, String>.from(knownHostFingerprints ?? _loadKnownHostFingerprints()), and _authenticatedClient gives that snapshot to a separate HostKeyVerifier. HostKeyVerifier.call reads and writes only its own _cache; promptHostKeyExclusively serializes dialogs but does not update or re-read another verifier's cache. Consequently two simultaneous first-use verifiers can both observe existing == null, receive different fingerprints, show the second prompt with isMismatch: false, and both return true before serialized persistence settles on the last write.
• SFTP overwrite can permanently delete the good destination when the replacement rename fails after the fallback removal. _replace removes path and then performs a second rename without restoring or retaining the old file; any permission, quota, disconnect, or other error on that second rename leaves neither the old destination nor the new file. This violates FileBackend.write's atomic replacement/integrity contract for servers without the POSIX rename extension. — The current SftpFileBackend._replace still executes _sftp.remove(path) and then _sftp.rename(staging, path) with no rollback or retained backup. If that second rename fails after the removal succeeds, the original destination has already been deleted and the staged replacement remains under its staging name, so the reported loss of both the good destination and replacement can still occur. The same delete-then-rename sequence also remains in _replaceRemote for transfers.
• monitor/install.sh: Upgrading from a malformed or incomplete package can permanently remove the working frontend and migrations and still report success. SBM_INSTALL_PKG is accepted after checking only the binary, while install_files deletes the existing frontend and migrations before copying those package paths; because the script does not use set -e or check the cp results, missing paths leave the service running without its panel/migrations and upgrade prints success.
• lib/core/sync.dart: The newer-schema refusal is not scoped to the sync attempt and can be bypassed by an overlapping sync, allowing an older copy to overwrite a newer remote file. fromFile clears the singleton marker at the start of every read, while backup later consults the shared marker; for example, sync A reads a too-new remote and yields after setting _remoteTooNew, sync B starts/reads any ordinary remote and clears it, then A reaches backup and uploads. The same singleton is used by automatic sync callers, so this is not limited to a UI double-tap. This is introduced by the static marker-based refusal design; it would be false only if SyncIface.sync serialized all calls globally and no other fromFile could run before the first call's backup decision. — The race remains in the current implementation: fromFile still clears the singleton marker before its asynchronous read, records the exception in the same shared marker on failure, and backup later reads that marker to decide whether to upload. Thus an overlapping sync can clear _remoteTooNew between the first sync's failed parse and its backup decision, allowing the upload. No per-attempt state or global serialization is present in lib/core/sync.dart.
• lib/data/model/file/transfer_worker.dart: Concurrent transfers to the same destination can reuse the same staging pathname and corrupt or delete each other's work.
• lib/data/provider/server/monitor_http.dart: The monitor backend treats FileBackend.write's optional size hint as an authoritative HTTP Content-Length. runCopy passes a listing/stat-derived size, but the interface explicitly says that value is only a hint and the source can change while it is being read. If the actual stream length differs, the agent's HTTP payload framing can terminate early or wait/fail instead of consuming the stream, so a valid copy can be rejected or committed with a truncated body; the monitor implementation does not validate the byte count before renaming. — fsWrite still forwards the optional, hint-only size directly as the HTTP content-length header ('content-length': ?size). When a caller supplies a stale size, the request framing can still disagree with the stream's actual bytes, and this client has no byte-count validation before the write is accepted.
• lib/data/model/file/transfer_worker.dart: The SFTP replacement fallback deletes the existing destination after any failed rename for which stat(path) succeeds, without establishing that the failure was caused by an existing destination. A permission, transport, or server-side rename failure can therefore turn a failed transfer into loss of the previously good destination, and the second rename can fail leaving neither file.
• lib/data/model/file/transfer_worker.dart: A download idle timeout races the still-running SFTP read: Future.any returns on the timeout, then the finally block closes the local file and later the SFTP resources while downloadFuture is not cancelled or awaited. The outstanding read can write to a closed file, produce unhandled errors, or continue consuming resources after the transfer has reported failure.
• lib/data/model/file/transfer_worker.dart: Specialized SFTP staging names are not unique across concurrent transfer isolates, so one transfer can overwrite or delete another transfer's in-progress staging file.
• lib/data/provider/pve.dart: TFA submission is not bound to the session generation that produced its challenge. submitTfaCode captures only _pendingTfaChallenge, then after awaits calls _loginWithTfaChallenge and performs _getRelease/list with only ref.mounted checks. If the user reconnects after the challenge dialog opens, the captured old challenge is sent through the replacement session and the result can set current state/auth headers or close/publish errors for the new generation.
• lib/core/utils/server.dart: A successful jump connection leaks the jump SSHClient and leaves it owning the forwarding transport with no lifecycle owner: the local variable is only closed in the catch path, while the successful path returns the forward channel and discards jumpClient. When the target client is later closed or the connection is disposed, there is no retained jump client to close, so the jump SSH session/socket can remain alive indefinitely. — The successful jump path still executes return await jumpClient.forwardLocal(ssh.ip, ssh.port); while jumpClient is only a local variable. The target client is retained by callers, but no jump client is retained alongside it or otherwise registered for teardown; jumpClient?.close() remains only in the catch path. Consequently, closing/discarding the returned target client still does not close the jump SSH session, so the reported leak can still occur.
• monitor/frontend/src/lib/api.ts: A late 401 from a previously selected server can log out the newly selected server. If a poll/request for A is in flight and the user switches to B before A responds, request() receives A's 401 but calls servers.logout(), whose implementation clears servers.current (now B), thereby deleting B's valid token and sessionStorage entry.
• DELETE /api/v1/fs/remove can delete the target of an in-root symlink instead of deleting the symlink itself. remove calls resolve_existing, which canonicalizes every symlink, and then calls symlink_metadata/remove_dir_all on that canonical target; for /srv/root/link -> /srv/root/important, a request for /srv/root/link becomes /srv/root/important and removes the target. This violates the handler's stated “a link is deleted, never followed” invariant and can turn a harmless shortcut deletion into destructive deletion of another in-root tree. The claim would be false if resolve_existing preserved the final directory entry (or if the target could not be removed by the resulting operation). — The current remove handler still calls resolve_existing(&body.path), and resolve_existing still returns std::fs::canonicalize(&path) after checking confinement. Thus an in-root symlink such as link -> important is converted to important; the subsequent symlink_metadata and remove_dir_all operate on the target, so deleting the link can still delete the target tree.
• Removing a symlink removes its canonical target rather than the symlink entry itself, contrary to the endpoint's documented remove semantics; a link inside one configured root can therefore delete a file or directory in another configured root. — The remove handler still calls roots.resolve_existing(&body.path), which canonicalizes and follows the requested symlink, and then passes that canonical target to symlink_metadata and remove_file/remove_dir_all. Thus a symlink inside one root that points to an existing file or directory in another root is rejected if the target is outside, but a symlink pointing to a target within a configured root is still removed by deleting the target rather than the link entry. The comment asserting links are deleted does not change the path returned by resolve_existing.

⚠️ Unverified risks (3)

• The app release jobs use an undefined BUILD_NUMBER, so tag/manual release packaging cannot rename or upload the expected artifacts and all release jobs target the wrong tag. (.github/workflows/build.yml)
• A completed/failed turn can mutate a different conversation after the user switches conversations during persistence. _handleEvent marks isStreaming false before awaiting _persist, and _persist has no conversation/session generation check; if activateConversation/restoreConversation runs while save(updated) is awaiting, the old continuation can write the old turn and then assign state.conversation, state.history, and conversations back over the newly selected conversation. The same window exists in runPendingTool, which sets isExecuting false before its awaited _persist. This loses or displays the newly selected conversation's state and can append the subsequent stream to the wrong history. This is introduced by the new async app-wide session/persistence flow; it would be disproved only if conversation switching were serialized with every persistence continuation (or the store save were proven synchronous/non-yielding in all supported backends). (lib/data/provider/ai/agent_session.dart)
• Local write confinement is a check-then-use race: _localPath(..., forWrite: true) resolves and validates the parent directory, but _writeLocalFile later constructs a temporary path and renames it without rechecking that parent. A concurrent process (including a previously launched/background guest command) can replace a checked in-root parent with a symlink to an outside directory between those operations; the temporary file and final rename then use the escaped path. Consequently the containment check is not an operation-safe confinement boundary for writes. (lib/data/provider/ai/global_agent_tools.dart)

📋 Additional findings from this change (not shown inline) (65)

• 🔴 Critical A failed read of an encrypted remote backup other than SchemaTooNewException does not set the upload-abort guard. fromFile catches the decryption/parse error, retries the payload without a password, and rethrows if that fails; _remoteTooNew remains null, so the subsequent SyncIface cycle can upload the local older backup over the unreadable remote and destroy remote-only data. (lib/core/sync.dart) — anchor-unreliable
• 🟠 High File uploads can be replayed after consuming a one-shot stream when the server returns 401: fsWrite calls _authed, whose 401 branch logs in and invokes fn() again with the same Stream<List<int>>. The second Dio request cannot read a single-subscription File.openRead stream and the upload fails (or can produce an incomplete write). (lib/data/provider/server/monitor_http.dart) — anchor-unreliable
• 🟠 High Each transfer isolate starts its own staging counter at zero, so concurrent workers can choose the same staging pathname for the same destination. Their writes then truncate and overwrite one another, and cancellation cleanup by one worker can delete the other worker's in-progress staging file. (lib/data/model/file/transfer_worker.dart) — anchor-outside-diff
• 🟠 High The optimized local-to-SFTP upload has no transfer/idle timeout after opening the remote staging file. writer.done is awaited directly, while job.timeoutSeconds is used only for session/file-open and final rename; a server that stops accepting upload data can leave the transfer isolate alive indefinitely (and retain the remote staged file until it is killed). This is false only if SftpFile.write(...).done has an independent bounded-progress timeout in dartssh2, rather than merely completing when the peer responds. (lib/data/model/file/transfer_worker.dart) — anchor-outside-diff
• 🟠 High Cancelling immediately after creating a status can fail to stop the transfer at all. The constructor starts _initWorker() unawaited; dispose() kills/disposes the worker, but _initWorker() has no disposed check and, after its await resumes, calls worker!.init() and then worker.sendMessage(job) unconditionally. Thus a cancel-before-init-completes race can recreate/start the worker after the row is removed, leaving an orphan transfer and SSH client that the user can no longer cancel or observe. (lib/data/model/file/transfer_status.dart) — anchor-outside-diff
• 🟠 High The startup server-ID migration starts async writes without awaiting them, and _doDbMigrate returns immediately after calling it. Provider construction or subsequent reads can therefore observe old IDs, while the cache watch may invalidate before/around the provider's initial fetch and the migration's later update is not reflected in provider state. (lib/data/store/server.dart) — anchor-unreliable
• 🟠 High A failed read of an encrypted remote backup can still cause the sync cycle to overwrite that remote with the local snapshot. For example, when the saved password is wrong (or decryption fails for a transient/corrupt payload), fromFile catches the error at the generic handler, retries the raw encrypted text through the legacy reader, and then throws again; the too-new guard is never set. The base sync implementation is documented here as catching merge failures and uploading unconditionally, while backup only refuses when _remoteTooNew is set, so the remote encrypted data is replaced by the older/incomplete local copy. This is introduced by the new fallback/guard arrangement; it would be disproved if the base sync implementation never uploads after a fromFile/merge exception or if all decryption failures are converted to _remoteTooNew/an equivalent upload-blocking state. (lib/core/sync.dart) — anchor-outside-diff
• 🟠 High Conversation switching does not invalidate the old stream callbacks. restoreConversation only calls cancel(); _handleEvent and the subscription's onError/onDone have no stream or conversation generation check. If a provider emits an already-delivered event after the user activates another conversation (or an async _handleEvent resumes after the switch), the old completion/delta is applied to the newly restored state, and _persist() saves that mixed history. The old turn can therefore appear in and be written to the newly selected conversation despite the selection change. (lib/data/provider/ai/agent_session.dart) — anchor-outside-diff
• 🟠 High The global shell output cap is applied only after ServerExec.run returns, but ProcessExec.run accumulates the complete stdout and stderr in unbounded StringBuffers before returning. A reviewed local command such as yes can therefore grow memory without bound (and can OOM the app) even though _runShell uses _BoundedTextAccumulator; the bounded callbacks do not prevent this second accumulation. (lib/core/utils/local_exec.dart) — anchor-outside-diff
• 🟠 High read_file is classified as read-only and is therefore eligible for unattended execution on any configured server, regardless of the path or sensitivity of the file. A model can propose read_file for /etc/shadow, a private key, cloud credentials, or application secrets with safe_to_run: true; canAutoRun is true and runPendingTool executes it without review, then puts the contents into the model conversation. Read-only does not mean non-sensitive, so this bypasses the stated review boundary for data access. (lib/data/model/ai/ask_ai_models.dart) — anchor-outside-diff
• 🟠 High Local read_file has the same TOCTOU escape after confinement: _localPath resolves the target and verifies it is under the root, then _readLocalFile creates a new File from the original host string and performs exists, length, and reads later. A symlink can be swapped after validation, so the read can follow an outside target and return host/app secrets despite the rootfs boundary. (lib/data/provider/ai/global_agent_tools.dart) — anchor-outside-diff
• 🟠 High Filesystem confinement is bypassable through a symlink swap between validation and use (monitor/src/api/fs.rs) — anchor-unreliable
• 🟠 High DATABASE_URL is ignored on the normal TOML loading path when the file omits database_url: Config::load deserializes the file and get_database_url() falls back directly to sqlite:serverbox_monitor.db, rather than consulting the environment. Thus a deployment with a valid config.toml (for example one containing only [server]/[monitoring]) and DATABASE_URL=/persistent/monitor.db silently opens the local default database, risking a fresh database and loss of the expected history/users. DATABASE_URL is consulted only by Config::default() and legacy normalization, so the behavior differs based solely on whether a TOML file exists. This would be false only if DATABASE_URL were intentionally supported exclusively for first-run/legacy migration, which conflicts with the documented environment configuration and the Docker/systemd use case. (monitor/src/core/config.rs) — anchor-outside-diff
• 🟠 High The monitor release matrix sets SQLX_OFFLINE=true but the repository has no monitor/.sqlx offline query cache, while the monitor contains sqlx::query! macros. A clean release run therefore fails during compilation with offline query-cache errors before producing native packages or the Docker image. (.github/workflows/monitor-release.yml) — anchor-outside-diff
• 🟠 High SFTP backend writes are not actually bounded by the configured operation timeout: after the staged file is opened, file.write(...).done is awaited directly. A stalled SFTP upload (including server-side backpressure or a lost channel that leaves the future pending) can therefore leave a server-to-server or monitor/SFTP copy running forever even though SftpFileBackend was constructed with _prepareTimeout(job). This is false only if the dartssh2 write future is independently guaranteed to complete or fail on every such stalled connection. (lib/core/utils/sftp_file_backend.dart) — inline-budget
• 🟠 High The legacy Backup reader accepts a future v1 payload version without rejecting it. Backup.fromJson delegates directly to generated deserialization, and MergeableUtils falls back to this reader after the V2 reader fails; a future/unsupported legacy-shaped file can therefore be partially decoded and merged instead of raising SchemaTooNewException, losing fields or deleting local records according to the incomplete payload. (lib/data/model/app/bak/backup.dart) — inline-budget
• 🟠 High Legacy remote inheritance can report success without importing any records when the v1 backup has a null or zero lastModTime. Backup.merge only restores when curTime < bakTime; with Stores.lastModTime at zero and a null/zero legacy timestamp, shouldRestore is false, yet inheritLegacyRemote logs that history was inherited and the new remote remains empty. (lib/data/model/app/bak/backup.dart) — inline-budget
• 🟠 High Snippet import has no name-conflict handling and can overwrite existing snippets while leaving duplicate in-memory identities. Each decoded item is passed to notifier.add; SnippetStore keys records by name, so an imported snippet with an existing name replaces that saved script, while SnippetNotifier.add appends it to state. Duplicate names within the same import have the same overwrite behavior, making list display/order and subsequent update/delete operations ambiguous. (lib/view/page/backup.dart) — inline-budget
• 🟠 High The per-SSH Agent also accepts stale stream events after history selection. _restoreConversation cancels the subscription and replaces the local conversation, but _handleEvent has no generation/identity guard and its async completion continues through await _persistConversation(). A late delta/completion from the prior conversation can consequently append to the selected conversation, set its pending command, and persist the prior turn into it after the user selected a different history row. (lib/view/page/ssh/page/ask_ai.dart) — inline-budget
• 🟠 High Cancellation/timeout can leave a local command running indefinitely and make the tool future hang. For example, sleep 600 & lets the shell process exit while the background child inherits stdout/stderr; ProcessExec.run then waits for outDone and errDone, but _kill only signals the shell's PID (not its process tree), so the global five-minute timeout's cancellation does not complete _runShell and the child remains alive. (lib/core/utils/local_exec.dart) — inline-budget
• 🟠 High The same supposed output bound is not enforced inside SSH execution: SshExec.run appends every received chunk to unbounded StringBuffers, while the global service only truncates after the SSH command and drain finish. A configured or ad-hoc host can run an unbounded-output command and force the client to retain the entire output for up to the five-minute operation timeout, defeating bounded-output protection and potentially exhausting memory. (lib/core/utils/ssh_exec.dart) — inline-budget
• 🟠 High migrateIds() can leave the provider permanently divergent from the migrated Hive records because it starts the delete/write operations without awaiting them. During startup _doDbMigrate() calls ServerStore.instance.migrateIds() and then returns, so a provider can build while the old key is still present and the new key is not yet visible; once the unawaited operations finish, CachedHiveStore invalidates its cache via box.watch(), but no provider reload is triggered. The UI can therefore retain the old-id server while persisted storage contains only the generated-id server (and server order/jump references may disagree). This is disproven if the store guarantees these unawaited operations complete synchronously before migrateIds() returns, or if provider construction is serialized behind them. (lib/data/store/server.dart) — anchor-unreliable
• 🟠 High Cancelling a monitor-agent shell call only abandons the HTTP wait; it does not stop the command on the remote host. MonitorExec.run returns an apparently cancelled empty result after cancel, while the request continues until the monitor's independent timeout. Thus a reviewed state-changing command (for example an install, migration, or rm) can continue and complete after the user presses Stop, even though the Agent reports Command cancelled; this violates cancellation semantics and can also leave remote work/resource usage running after the conversation has moved on. (lib/core/utils/monitor_exec.dart) — anchor-unreliable
• 🟡 Medium Explicit per-entry capability/status requests do not handle expired credentials or network failures according to the API contract: getCapabilitiesFor and getStatusFor throw a generic error for 401/non-2xx and let fetch rejection escape as a raw TypeError, without clearing that entry's stale token or normalizing to ApiError with status. (monitor/frontend/src/lib/api.ts) — inline-budget
• 🟡 Medium A 401 from an in-flight request can log out the wrong server after the user switches servers. request() captures servers.current for the URL/token, but on an unauthorized response it calls the unqualified servers.logout(), which clears whatever entry is current at response time. For example, a slow poll to server A returns 401 after the user selects server B; B's valid token is deleted and the UI is forced back to login even though B was never rejected. This is introduced by the new multi-server request/session handling; it would be disproven if server selection were guaranteed not to change for the lifetime of every request. Logout needs to be scoped to the entry/id used for the request (and ideally only if its token is still the same). (monitor/frontend/src/lib/api.ts) — inline-budget
• 🟡 Medium The explicit per-entry status/capabilities helpers do not implement the auth and network error contract that the shared request path does. getStatusFor() and getCapabilitiesFor() call fetch() without a catch and never handle 401, so an expired token for a sidebar/name entry is left in sessionStorage and the entry remains authenticated; every name refresh/capability retry keeps using the dead bearer instead of clearing that session or surfacing an ApiError with its HTTP status. This is observable when an agent expires/revokes a token while the panel is open, and would be false only if these helpers were never used after token expiry or another layer explicitly converted 401s and removed the entry (their callers only catch and retain the old state). (monitor/frontend/src/lib/api.ts) — inline-budget
• 🟡 Medium Disposing a transfer does not cancel its queued prompt callback. mainMessageHandler always awaits PromptQueue.shared.add(...) and then sends a response, with no disposed/generation check; if a transfer is cancelled while its host-key or keyboard-interactive question is waiting behind another dialog, the callback still runs later and can display a prompt for the already-dead transfer. Its response is sent to a killed isolate, while the shared queue remains occupied until the user answers or the prompt timeout expires. (lib/data/model/file/transfer_worker.dart) — inline-budget
• 🟡 Medium Forgetting a host key can be undone by an already queued host-key persistence write. (lib/core/utils/server.dart) — inline-budget
• 🟡 Medium A legacy JSON record can fail an immediate update after fetch: _getAndConvert returns the decoded item but schedules putRaw unawaited, so have(old) still calls get<T> and returns null until that write completes. Any provider update invoked in that window throws 'Old ... not found' even though fetch exposed the record, and the provider/persistence state remains unchanged. (lib/data/store/cached_store.dart) — inline-budget
• 🟡 Medium Adding a private key with an ID already present appends a second entry to Riverpod state while Hive stores only one record under that ID. The editor allows arbitrary name input and PrivateKeyNotifier.add constructs [...state.keys, info] without checking identity; the next reload collapses the duplicate, so the UI and persisted state diverge until reload and one logical key is silently replaced. (lib/data/provider/private_key.dart) — inline-budget
• 🟡 Medium ServerDeduplication.deduplicateServers compares each imported server only with the pre-existing list, not with already accepted imports. Two identical servers in one import therefore both survive deduplication; importServersWithNotification then calls addServer twice, producing duplicate IDs in serverOrder and duplicate live-state entries (or overwriting the same Hive record). (lib/core/utils/server_dedup.dart) — inline-budget
• 🟡 Medium Legacy remote inheritance silently fails for a valid old backup whose lastModTime is absent or zero, which is precisely a supported shape (Backup.lastModTime is nullable). inheritLegacyRemote calls merge() without force, and Backup.merge computes shouldRestore = force || curTime < bakTime; on a fresh store Stores.lastModTime is 0 and a legacy file with null/0 has bakTime 0, so it logs 'local is newer' and imports none of the servers/snippets/keys/etc. The subsequent code still logs the inheritance attempt as successful. This is introduced/exposed by the new legacy migration path; it would be disproved if every legacy backup ever written is guaranteed to contain a strictly positive lastModTime and fresh initialized stores always report a value greater than zero. (lib/data/model/app/bak/backup.dart) — inline-budget
• 🟡 Medium PrivateKeyNotifier.update can delete the newly written key when the old record is absent and both objects have the same id. In the idx == -1 branch it awaits Stores.key.put(newInfo) and then unconditionally awaits Stores.key.delete(old); delete keys by id, so a stale provider state or an external deletion causes the replacement just written to be removed. The update/delete tests do not exercise this stale-store case. This would be disproved if callers could guarantee that idx == -1 implies old.id != newInfo.id (or that the old store entry always exists). (lib/data/provider/private_key.dart) — inline-budget
• 🟡 Medium Private-key save failures are rethrown after only a toast, so an invalid PEM/decryption failure becomes an unhandled asynchronous exception rather than a contained UI error. _onTapSave catches the isolate error, calls Toast.error, then rethrow; because the FAB callback is not awaited by Flutter, the page gets no error dialog and the exception is reported as an uncaught future error. The same pattern can occur for persistence failures after validation. (lib/view/page/private_key/edit.dart) — inline-budget
• 🟡 Medium Continuing a persisted conversation does not preserve the conversation's provider/model metadata: every Agent request reads the current global settings, and each save overwrites the stored providerBaseUrl/model with those settings. If a user changes endpoint or model after creating a conversation, the next turn is sent to the new model with the old transcript and the record is rewritten, so replay/continuation no longer has the metadata it was created under. (lib/data/provider/ai/agent_session.dart) — anchor-unreliable
• 🟡 Medium Persistence has the same stale-identity race even without a late stream event. _persist captures the current conversation, awaits save, and then unconditionally assigns state.conversation/history from that saved record. A completed turn sets isStreaming false before awaiting _persist, so activateConversation can restore another conversation during that await; when the old save returns it replaces the newly selected state with the old turn. The same issue exists after tool execution/decline because those methods also await _persist after clearing their working flag. (lib/data/provider/ai/agent_session.dart) — inline-budget
• 🟡 Medium Stopping a streamed turn is not durable. stopWork cancels the subscription and appends an interrupted notice only to state.timeline, but does not append a corresponding assistant/history item or call _persist. After restart or switching away and reopening the conversation, the persisted user prompt has neither a response nor an interruption marker, so replay presents the turn as an unresolved conversation and can leave the protocol history inconsistent with what the user saw. (lib/data/provider/ai/agent_session.dart) — inline-budget
• 🟡 Medium The JSON replay serializer forwards orphan function outputs even though replay treats them as unmatched: _chatMessages emits every AskAiFunctionOutputItem as a role: tool message without checking that a preceding serialized function call with the same ID exists. A restored/old conversation containing a raw or declined/tool-result item whose call was trimmed or not persisted (or an output with a typo in call_id) produces a Chat Completions request rejected for an invalid tool message instead of replaying the usable remainder. This would be false only if storage migration guarantees every output always has its matching call and trimming can never leave an orphan. (lib/data/provider/ai/ask_ai.dart) — inline-budget
• 🟡 Medium The default systemd user install attempts enable/restart before ensuring a user systemd manager exists, so headless installs commonly fail to start or enable the service. (monitor/install.sh) — anchor-unreliable
• 🟡 Medium Live server names remain cached after logout, removal, or URL replacement and can be displayed for a different unauthenticated/reused server entry. (monitor/frontend/src/lib/serverNames.svelte.ts) — inline-budget
• 🟡 Medium Invalid push rate values such as 0/0s are accepted and silently disable or effectively remove the intended rate limit. (monitor/src/core/config.rs) — inline-budget
• 🟡 Medium Local shell startup leaks an orphan shell when PTY setup fails after spawning the child (monitor/src/ssh/local_pty.rs) — inline-budget
• 🟡 Medium The live server-name cache is not invalidated when an entry is logged out or its URL is changed, so the sidebar can continue displaying the previous agent's name for an unauthenticated/different server indefinitely. (monitor/frontend/src/lib/servers.svelte.ts) — inline-budget
• 🟡 Medium Environment configuration does not consistently take precedence over a TOML file: when config.toml contains a [server] section, get_server() returns that section verbatim, so SBM_HOST, SBM_PORT, and SBM_TLS_CERT/SBM_TLS_KEY are ignored (the same variables are only consulted by ServerConfig::default() when the entire section is absent). A deployment that keeps a normal [server] section and changes SBM_PORT therefore continues listening on the old port, while the documented/configuration contract says environment is the primary channel and the CLI code only treats explicit --addr as the override. This is introduced/exposed by the new partial-default/precedence arrangement in Config::get_server and apply_env_overrides, which only applies JWT and CORS. It would be false if the intended contract were that these server environment variables apply only when [server] is absent, contrary to the environment documentation and ServerConfig::default comments. (monitor/src/core/config.rs) — inline-budget
• 🟡 Medium PUT /api/v1/settings accepts zero for both optional runtime cadence fields even though the UI and configuration semantics require a positive interval. A request with extended_interval_secs: 0 persists zero; effective_extended_interval_secs() returns it unchanged, and is_extended_cycle then divides by interval_seconds and clamps the resulting cadence to 1, causing the expensive extended script to run every core cycle. Likewise idle_pause_threshold_secs: 0 makes should_run_extended false whenever idle-pause is enabled, so extended collection is effectively disabled after the first elapsed second. The endpoint validates only interval_seconds, and the TOML deserializer also accepts these values. This would be false only if zero were deliberately documented as a supported alias for “every cycle”/“always pause”; the frontend uses min="1", comments describe unset/null—not zero—as the default, and the resulting behavior is not exposed as such. (monitor/src/api/server.rs) — inline-budget
• 🟡 Medium The Agent history-column breakpoint test does not actually test the narrow 700px layout because its helper changes only the test surface, not the view size reported through MediaQuery. AgentPage delegates the split decision to AdaptiveSideList, whose adaptive width logic uses the view/media-query dimensions; therefore the width: 700 case can still be laid out at the default 1200px test view and pass findsFalse without exercising the narrow branch. This leaves the changed responsive Agent widget coverage unreliable. (test/agent_view_test.dart) — inline-budget
• 🟡 Medium PRs changing Android native sources (and other unlisted platform/build workflow files) can receive no relevant analysis job: the changes filter only treats analysis.yml, pubspec, packages, Dart/test, Rust, iOS, and selected scripts as coverage. For example, a change to android/app/src/main/AndroidManifest.xml makes rust/ish/dart/frontend/docs/website all false, while build.yml does not run on pull_request. (.github/workflows/analysis.yml) — inline-budget
• 🟡 Medium Changes to build.yml, macos.yml, monitor-release.yml, dependabot/configuration, or other workflow files do not invalidate the change-aware analysis filters unless analysis.yml itself changes. A PR can therefore modify release permissions, artifact naming, matrices, or monitor CI replacement and have every expensive analysis job skipped. (.github/workflows/analysis.yml) — inline-budget
• 🟡 Medium Persisted conversation metadata does not control replay requests: restoring a conversation records protocol, provider_base_url, and model, but AgentSession.startStream passes only the history and protocol, while AskAiRepository.ask always rereads the current settings for base URL and model. After the user changes provider/model settings, continuing an old conversation therefore sends its old transcript to the new model/endpoint, and _persist then overwrites the conversation metadata with the new settings. This is false only if these fields are intentionally audit-only and switching provider/model for an existing conversation is explicitly supported. (lib/data/provider/ai/ask_ai.dart) — anchor-unreliable
• 🟡 Medium Disposal does not reliably terminate a concurrent login: dispose() clears _loginFuture, but an already-running _loginImpl can resume afterward, call _session(), restore _token and the Authorization header, and recreate the Dio session after disposal. (lib/data/provider/server/monitor_http.dart) — inline-budget
• 🟡 Medium Watch-token revocation for an endpoint change can leave the old token active: _revokeServer uses the old endpoint from application context but copies the current monitor username/password. If the monitor credentials were changed along with the endpoint (or the old endpoint has different credentials), revocation fails and the old scoped token remains valid until expiry. (lib/core/service/watch_sync.dart) — inline-budget
• 🟡 Medium Replacing a server entry leaks the old watch-side URLSession: shared(for:) overwrites cache[server.id] when the value changes but never calls invalidateAndCancel() on the discarded client/session, leaving its connection pool and in-flight work alive. (ios/WatchApp/MonitorClient.swift) — inline-budget
• 🟡 Medium Inline cancellation is not checked after a file's write completes, so a cancellation during the final chunk can still publish a successful transfer and leave the destination replaced. runCopy checks cancellation before each chunk, but after the stream finishes it immediately awaits dest.write(...) and then returns; _runHere emits finished without another check. A one-file local/monitor transfer cancelled after its last chunk but before write resolves therefore completes despite _disposed, unlike the documented cancellation behavior. (lib/data/model/file/copy_tree.dart) — inline-budget
• 🟡 Medium A successful ProxyJump connection leaks the jump SSH client for the entire lifetime of the app (and often beyond the target session). (lib/core/utils/server.dart) — inline-budget
• 🟡 Medium Stop/timeout cancellation does not cancel monitor-backed server operations. cancelCurrent only completes _cancelRun, which is installed by _runShell; serverbox connect/refresh instead awaits refresh().timeout(_operationTimeout) with no cancellation signal. If a monitor request hangs, pressing Stop returns without stopping it, and the underlying refresh can later mutate server connection/status after the Agent turn was stopped (and after the UI/conversation may have changed). (lib/data/provider/ai/global_agent_tools.dart) — inline-budget
• 🟡 Medium The SSH Ask AI panel still implements an independent conversation/stream/tool state machine instead of consuming the app-scoped AgentSession. It owns _history, _conversation, _subscription, pending command, execution and persistence, while the global Agent uses the separate global_agent conversation. Opening the SSH Agent and the global Agent therefore shows different sessions and can run/approve concurrently; a turn started in one view is not visible or stoppable from the other, violating the required app-wide session contract. (lib/view/page/ssh/page/ask_ai.dart) — inline-budget
• 🟡 Medium AskAiCommandResult.tryFromToolMessage classifies any JSON object containing either stdout or stderr as a successful tool-result record, without requiring a result discriminator, types for the fields, or the expected command/call identity. Consequently a provider/tool output such as {"stdout":"model-generated text"} (or a stored raw output from an older schema) is rendered as an execution result and is not shown as an untrusted notice; replay can therefore claim a command has a result when no executor produced one. This is false only if the tool-output boundary guarantees that every such JSON object is exclusively app-generated and old/raw outputs cannot reach this parser. (lib/data/model/ai/ask_ai_models.dart) — inline-budget
• 🟡 Medium The default systemd user install cannot bootstrap on hosts without an already-running per-user manager (monitor/install.sh) — inline-budget
• 🟡 Medium Expired watch tokens are reused indefinitely, so a watch configured for more than 90 days eventually becomes permanently unable to load metrics until the server address changes or the selection is recreated. (lib/core/service/watch_sync.dart) — anchor-unreliable
• 🟡 Medium Disposal can be undone by an in-flight login. If dispose() runs while _loginImpl() is awaiting /login, dispose clears _dio and _loginFuture; when the login completes, _loginImpl assigns _token and calls _session(), which creates a new Dio because _dio was nulled. The supposedly disposed client therefore resurrects a live HTTP session (and leaves it unclosed), and a caller awaiting the original operation can continue using it. This is false only if callers can prove dispose never overlaps a login request. (lib/data/provider/server/monitor_http.dart) — anchor-unreliable
• 🟡 Medium Watch-token revocation uses the current monitor credentials even when revoking a token issued for an earlier credential. _revokeServer constructs the client with monitor.user/monitor.pwd from the current Spi while using only the old endpoint from application context. If the monitor password/user changes and the server is then removed or its endpoint changes, login at the old endpoint fails and /watch-token is never reached; the old read-only token remains valid for up to the agent's 90-day lifetime. This would be disproved only if monitor credentials are immutable for the lifetime of every watch token or the server invalidates those tokens on credential changes. (lib/core/service/watch_sync.dart) — anchor-unreliable
• 🟡 Medium The backup page can write to a disposed loading notifier after its route is removed during an in-flight operation. For example, _onTapWebdavDl awaits WebDAV listing, a file picker, download, and restore; if the page is popped during any await, dispose() runs webdavLoading.dispose(), and the unconditional finally { webdavLoading.value = false; } then updates the disposed notifier (the analogous Gist/WebDAV upload paths have the same pattern). This is a likely teardown-time exception and there is no widget test that disposes the page while one of these async callbacks is pending. The claim would be false if the notifier implementation explicitly permits writes after disposal or the operation is guaranteed to cancel before route disposal. (lib/view/page/backup.dart) — anchor-unreliable
• 🟡 Medium Environment host/port/TLS overrides are ignored whenever a TOML file contains a [server] section (including the generated default config). (monitor/src/core/config.rs) — anchor-unreliable
• 🟡 Medium Local PTY startup can leave the newly spawned shell orphaned when take_writer or try_clone_reader fails. (monitor/src/ssh/local_pty.rs) — anchor-unreliable
• 🟡 Medium A zero cleanup interval can crash the cleanup task at startup instead of being rejected or safely disabled. start_cleanup_scheduler converts cleanup_interval_hours directly to a Tokio interval period; Duration::from_secs(0) is passed to tokio::time::interval, which panics because a zero period is invalid. The settings endpoint validates interval_seconds but does not validate any data_retention fields, and config deserialization/defaults likewise permit zero, so an authenticated settings update (or a hand-edited config) can set cleanup_interval_hours = 0; this leaves retention/size cleanup unavailable and can produce a task panic. This would be false only if another config-validation layer guarantees the value is always >=1 before scheduler construction. (monitor/src/db/cleanup.rs) — anchor-unreliable

❓ Low-evidence leads (not confirmed — verify before acting) (2)

• Malformed password hashes for an existing account escape the normal invalid-login path: verify_login_password returns an error, so login propagates a 500 instead of recording a failure and returning 401/429. (monitor/src/api/auth.rs)
• Late stream events can mutate the wrong global conversation. restoreConversation cancels the subscription but does not establish a generation/token, and _handleEvent/onError/onDone unconditionally write state; stream cancellation is asynchronous and an already-delivered callback can complete after the user switches conversations. Such a callback can append assistant output, tool calls, or errors to the newly restored conversation and _persist then saves that mixed history. (lib/data/provider/ai/agent_session.dart)

## Unresolved from the previous review — these block approval, fix them first (14)

Somewhere in the code under review, address this finding:
Browser TOFU is raceable across simultaneous connections that start with separate cache snapshots. `genClient` copies the global store into `hostKeyCache` before constructing each verifier; two connections that see no pin can both prompt, and if they receive different offered keys, `promptHostKeyExclusively` merely serializes the dialogs rather than re-reading or atomically claiming the pin. Each verifier then writes its own key and returns true, while the serialized persistence queue eventually leaves whichever key was persisted last. Thus both a legitimate key and a concurrent impostor can be accepted during first use, and the second prompt is shown as `isMismatch: false` instead of comparing against the first winner. This would be proven false only if all concurrent `genClient` calls are guaranteed to share one mutable cache or the underlying SSH callback cannot concurrently offer different keys.

Somewhere in the code under review, address this finding:
SFTP overwrite can permanently delete the good destination when the replacement rename fails after the fallback removal. `_replace` removes `path` and then performs a second rename without restoring or retaining the old file; any permission, quota, disconnect, or other error on that second rename leaves neither the old destination nor the new file. This violates `FileBackend.write`'s atomic replacement/integrity contract for servers without the POSIX rename extension.

In monitor/install.sh, address this finding:
Upgrading from a malformed or incomplete package can permanently remove the working frontend and migrations and still report success. `SBM_INSTALL_PKG` is accepted after checking only the binary, while `install_files` deletes the existing `frontend` and `migrations` before copying those package paths; because the script does not use `set -e` or check the `cp` results, missing paths leave the service running without its panel/migrations and `upgrade` prints success.

In lib/core/sync.dart, address this finding:
The newer-schema refusal is not scoped to the sync attempt and can be bypassed by an overlapping sync, allowing an older copy to overwrite a newer remote file. `fromFile` clears the singleton marker at the start of every read, while `backup` later consults the shared marker; for example, sync A reads a too-new remote and yields after setting `_remoteTooNew`, sync B starts/reads any ordinary remote and clears it, then A reaches `backup` and uploads. The same singleton is used by automatic sync callers, so this is not limited to a UI double-tap. This is introduced by the static marker-based refusal design; it would be false only if `SyncIface.sync` serialized all calls globally and no other `fromFile` could run before the first call's backup decision.

In lib/data/model/file/transfer_worker.dart, address this finding:
Concurrent transfers to the same destination can reuse the same staging pathname and corrupt or delete each other's work.

In lib/data/provider/server/monitor_http.dart, address this finding:
The monitor backend treats `FileBackend.write`'s optional `size` hint as an authoritative HTTP Content-Length. `runCopy` passes a listing/stat-derived size, but the interface explicitly says that value is only a hint and the source can change while it is being read. If the actual stream length differs, the agent's HTTP payload framing can terminate early or wait/fail instead of consuming the stream, so a valid copy can be rejected or committed with a truncated body; the monitor implementation does not validate the byte count before renaming.

In lib/data/model/file/transfer_worker.dart, address this finding:
The SFTP replacement fallback deletes the existing destination after any failed rename for which stat(path) succeeds, without establishing that the failure was caused by an existing destination. A permission, transport, or server-side rename failure can therefore turn a failed transfer into loss of the previously good destination, and the second rename can fail leaving neither file.

In lib/data/model/file/transfer_worker.dart, address this finding:
A download idle timeout races the still-running SFTP read: Future.any returns on the timeout, then the finally block closes the local file and later the SFTP resources while downloadFuture is not cancelled or awaited. The outstanding read can write to a closed file, produce unhandled errors, or continue consuming resources after the transfer has reported failure.

In lib/data/model/file/transfer_worker.dart, address this finding:
Specialized SFTP staging names are not unique across concurrent transfer isolates, so one transfer can overwrite or delete another transfer's in-progress staging file.

In lib/data/provider/pve.dart, address this finding:
TFA submission is not bound to the session generation that produced its challenge. submitTfaCode captures only _pendingTfaChallenge, then after awaits calls _loginWithTfaChallenge and performs _getRelease/list with only ref.mounted checks. If the user reconnects after the challenge dialog opens, the captured old challenge is sent through the replacement session and the result can set current state/auth headers or close/publish errors for the new generation.

In lib/core/utils/server.dart, address this finding:
A successful jump connection leaks the jump SSHClient and leaves it owning the forwarding transport with no lifecycle owner: the local variable is only closed in the catch path, while the successful path returns the forward channel and discards jumpClient. When the target client is later closed or the connection is disposed, there is no retained jump client to close, so the jump SSH session/socket can remain alive indefinitely.

In monitor/frontend/src/lib/api.ts, address this finding:
A late 401 from a previously selected server can log out the newly selected server. If a poll/request for A is in flight and the user switches to B before A responds, `request()` receives A's 401 but calls `servers.logout()`, whose implementation clears `servers.current` (now B), thereby deleting B's valid token and sessionStorage entry.

Somewhere in the code under review, address this finding:
`DELETE /api/v1/fs/remove` can delete the target of an in-root symlink instead of deleting the symlink itself. `remove` calls `resolve_existing`, which canonicalizes every symlink, and then calls `symlink_metadata`/`remove_dir_all` on that canonical target; for `/srv/root/link -> /srv/root/important`, a request for `/srv/root/link` becomes `/srv/root/important` and removes the target. This violates the handler's stated “a link is deleted, never followed” invariant and can turn a harmless shortcut deletion into destructive deletion of another in-root tree. The claim would be false if `resolve_existing` preserved the final directory entry (or if the target could not be removed by the resulting operation).

Somewhere in the code under review, address this finding:
Removing a symlink removes its canonical target rather than the symlink entry itself, contrary to the endpoint's documented remove semantics; a link inside one configured root can therefore delete a file or directory in another configured root.

## Findings on this change (also posted as inline comments) (5)

In ios/WatchApp/MonitorClient.swift around line 126, address this finding:
The watch sends bearer watch tokens to any URL in its stored/pushed `WatchServer`, without enforcing HTTPS or loopback HTTP. `get` constructs a URL and sets Authorization before `send`, and `loadLegacy` also accepts arbitrary URLs (though legacy is unauthenticated). A malicious/corrupt WatchConnectivity payload or stale insecure monitor configuration can therefore leak the scoped token over plaintext HTTP.

In lib/core/service/watch_sync.dart around line 140, address this finding:
Watch tokens are reused without considering their server-issued expiry, so a watch that remains configured for more than 90 days never receives a replacement token and stays unauthorized indefinitely.

In lib/view/page/backup.dart around line 849, address this finding:
A bulk server import can overwrite existing servers and leave the live provider/order state stale.

In lib/view/page/private_key/edit.dart around line 287, address this finding:
Saving a new private key with an existing name overwrites the existing key without a conflict check, while the notifier appends a second in-memory entry. The editor constructs `PrivateKeyInfo(id: name, ...)` and calls `add`; the store key is `id`, so `put` replaces the old PEM, and `PrivateKeyNotifier.add` builds `[..., info]` rather than rejecting the duplicate. Servers referring to that key ID therefore start using a different private key, and the key UI can show duplicate rows.

In lib/view/page/private_key/edit.dart around line 285, address this finding:
Renaming a private key to the ID of another existing key can delete/replace the wrong identity. `PrivateKeyNotifier.update` delegates to `CachedHiveStore.update`, which writes the new ID (overwriting any key already stored there) and then removes the old ID; the editor allows any non-empty name and performs no collision check. A rename from A to B therefore destroys B's key and leaves servers referencing B with the renamed A material.

## Additional findings on this change (not posted inline) (65)

In lib/core/sync.dart, address this finding:
A failed read of an encrypted remote backup other than SchemaTooNewException does not set the upload-abort guard. fromFile catches the decryption/parse error, retries the payload without a password, and rethrows if that fails; _remoteTooNew remains null, so the subsequent SyncIface cycle can upload the local older backup over the unreadable remote and destroy remote-only data.

In lib/data/provider/server/monitor_http.dart, address this finding:
File uploads can be replayed after consuming a one-shot stream when the server returns 401: `fsWrite` calls `_authed`, whose 401 branch logs in and invokes `fn()` again with the same `Stream<List<int>>`. The second Dio request cannot read a single-subscription `File.openRead` stream and the upload fails (or can produce an incomplete write).

In lib/data/model/file/transfer_worker.dart around line 477, address this finding:
Each transfer isolate starts its own staging counter at zero, so concurrent workers can choose the same staging pathname for the same destination. Their writes then truncate and overwrite one another, and cancellation cleanup by one worker can delete the other worker's in-progress staging file.

In lib/data/model/file/transfer_worker.dart around line 605, address this finding:
The optimized local-to-SFTP upload has no transfer/idle timeout after opening the remote staging file. `writer.done` is awaited directly, while `job.timeoutSeconds` is used only for session/file-open and final rename; a server that stops accepting upload data can leave the transfer isolate alive indefinitely (and retain the remote staged file until it is killed). This is false only if `SftpFile.write(...).done` has an independent bounded-progress timeout in dartssh2, rather than merely completing when the peer responds.

In lib/data/model/file/transfer_status.dart around line 133, address this finding:
Cancelling immediately after creating a status can fail to stop the transfer at all. The constructor starts `_initWorker()` unawaited; `dispose()` kills/disposes the worker, but `_initWorker()` has no disposed check and, after its await resumes, calls `worker!.init()` and then `worker.sendMessage(job)` unconditionally. Thus a cancel-before-init-completes race can recreate/start the worker after the row is removed, leaving an orphan transfer and SSH client that the user can no longer cancel or observe.

In lib/data/store/server.dart, address this finding:
The startup server-ID migration starts async writes without awaiting them, and _doDbMigrate returns immediately after calling it. Provider construction or subsequent reads can therefore observe old IDs, while the cache watch may invalidate before/around the provider's initial fetch and the migration's later update is not reflected in provider state.

In lib/core/sync.dart around line 72, address this finding:
A failed read of an encrypted remote backup can still cause the sync cycle to overwrite that remote with the local snapshot. For example, when the saved password is wrong (or decryption fails for a transient/corrupt payload), `fromFile` catches the error at the generic handler, retries the raw encrypted text through the legacy reader, and then throws again; the too-new guard is never set. The base sync implementation is documented here as catching merge failures and uploading unconditionally, while `backup` only refuses when `_remoteTooNew` is set, so the remote encrypted data is replaced by the older/incomplete local copy. This is introduced by the new fallback/guard arrangement; it would be disproved if the base sync implementation never uploads after a `fromFile`/merge exception or if all decryption failures are converted to `_remoteTooNew`/an equivalent upload-blocking state.

In lib/data/provider/ai/agent_session.dart around line 428, address this finding:
Conversation switching does not invalidate the old stream callbacks. `restoreConversation` only calls `cancel()`; `_handleEvent` and the subscription's `onError`/`onDone` have no stream or conversation generation check. If a provider emits an already-delivered event after the user activates another conversation (or an async `_handleEvent` resumes after the switch), the old completion/delta is applied to the newly restored `state`, and `_persist()` saves that mixed history. The old turn can therefore appear in and be written to the newly selected conversation despite the selection change.

In lib/core/utils/local_exec.dart around line 160, address this finding:
The global shell output cap is applied only after `ServerExec.run` returns, but `ProcessExec.run` accumulates the complete stdout and stderr in unbounded `StringBuffer`s before returning. A reviewed local command such as `yes` can therefore grow memory without bound (and can OOM the app) even though `_runShell` uses `_BoundedTextAccumulator`; the bounded callbacks do not prevent this second accumulation.

In lib/data/model/ai/ask_ai_models.dart around line 381, address this finding:
`read_file` is classified as read-only and is therefore eligible for unattended execution on any configured server, regardless of the path or sensitivity of the file. A model can propose `read_file` for `/etc/shadow`, a private key, cloud credentials, or application secrets with `safe_to_run: true`; `canAutoRun` is true and `runPendingTool` executes it without review, then puts the contents into the model conversation. Read-only does not mean non-sensitive, so this bypasses the stated review boundary for data access.

In lib/data/provider/ai/global_agent_tools.dart around line 1101, address this finding:
Local `read_file` has the same TOCTOU escape after confinement: `_localPath` resolves the target and verifies it is under the root, then `_readLocalFile` creates a new `File` from the original host string and performs `exists`, `length`, and reads later. A symlink can be swapped after validation, so the read can follow an outside target and return host/app secrets despite the rootfs boundary.

In monitor/src/api/fs.rs, address this finding:
Filesystem confinement is bypassable through a symlink swap between validation and use

In monitor/src/core/config.rs around line 449, address this finding:
`DATABASE_URL` is ignored on the normal TOML loading path when the file omits `database_url`: `Config::load` deserializes the file and `get_database_url()` falls back directly to `sqlite:serverbox_monitor.db`, rather than consulting the environment. Thus a deployment with a valid `config.toml` (for example one containing only `[server]`/`[monitoring]`) and `DATABASE_URL=/persistent/monitor.db` silently opens the local default database, risking a fresh database and loss of the expected history/users. `DATABASE_URL` is consulted only by `Config::default()` and legacy normalization, so the behavior differs based solely on whether a TOML file exists. This would be false only if `DATABASE_URL` were intentionally supported exclusively for first-run/legacy migration, which conflicts with the documented environment configuration and the Docker/systemd use case.

In .github/workflows/monitor-release.yml around line 124, address this finding:
The monitor release matrix sets SQLX_OFFLINE=true but the repository has no monitor/.sqlx offline query cache, while the monitor contains sqlx::query! macros. A clean release run therefore fails during compilation with offline query-cache errors before producing native packages or the Docker image.

In lib/core/utils/sftp_file_backend.dart around line 225, address this finding:
SFTP backend writes are not actually bounded by the configured operation timeout: after the staged file is opened, `file.write(...).done` is awaited directly. A stalled SFTP upload (including server-side backpressure or a lost channel that leaves the future pending) can therefore leave a server-to-server or monitor/SFTP copy running forever even though `SftpFileBackend` was constructed with `_prepareTimeout(job)`. This is false only if the dartssh2 write future is independently guaranteed to complete or fail on every such stalled connection.

In lib/data/model/app/bak/backup.dart around line 44, address this finding:
The legacy Backup reader accepts a future v1 payload version without rejecting it. Backup.fromJson delegates directly to generated deserialization, and MergeableUtils falls back to this reader after the V2 reader fails; a future/unsupported legacy-shaped file can therefore be partially decoded and merged instead of raising SchemaTooNewException, losing fields or deleting local records according to the incomplete payload.

In lib/data/model/app/bak/backup.dart around line 75, address this finding:
Legacy remote inheritance can report success without importing any records when the v1 backup has a null or zero lastModTime. Backup.merge only restores when curTime < bakTime; with Stores.lastModTime at zero and a null/zero legacy timestamp, shouldRestore is false, yet inheritLegacyRemote logs that history was inherited and the new remote remains empty.

In lib/view/page/backup.dart around line 555, address this finding:
Snippet import has no name-conflict handling and can overwrite existing snippets while leaving duplicate in-memory identities. Each decoded item is passed to `notifier.add`; `SnippetStore` keys records by `name`, so an imported snippet with an existing name replaces that saved script, while `SnippetNotifier.add` appends it to state. Duplicate names within the same import have the same overwrite behavior, making list display/order and subsequent update/delete operations ambiguous.

In lib/view/page/ssh/page/ask_ai.dart around line 375, address this finding:
The per-SSH Agent also accepts stale stream events after history selection. `_restoreConversation` cancels the subscription and replaces the local conversation, but `_handleEvent` has no generation/identity guard and its async completion continues through `await _persistConversation()`. A late delta/completion from the prior conversation can consequently append to the selected conversation, set its pending command, and persist the prior turn into it after the user selected a different history row.

In lib/core/utils/local_exec.dart around line 184, address this finding:
Cancellation/timeout can leave a local command running indefinitely and make the tool future hang. For example, `sleep 600 &` lets the shell process exit while the background child inherits stdout/stderr; `ProcessExec.run` then waits for `outDone` and `errDone`, but `_kill` only signals the shell's PID (not its process tree), so the global five-minute timeout's cancellation does not complete `_runShell` and the child remains alive.

In lib/core/utils/ssh_exec.dart around line 59, address this finding:
The same supposed output bound is not enforced inside SSH execution: `SshExec.run` appends every received chunk to unbounded `StringBuffer`s, while the global service only truncates after the SSH command and drain finish. A configured or ad-hoc host can run an unbounded-output command and force the client to retain the entire output for up to the five-minute operation timeout, defeating bounded-output protection and potentially exhausting memory.

In lib/data/store/server.dart, address this finding:
`migrateIds()` can leave the provider permanently divergent from the migrated Hive records because it starts the delete/write operations without awaiting them. During startup `_doDbMigrate()` calls `ServerStore.instance.migrateIds()` and then returns, so a provider can build while the old key is still present and the new key is not yet visible; once the unawaited operations finish, `CachedHiveStore` invalidates its cache via `box.watch()`, but no provider reload is triggered. The UI can therefore retain the old-id server while persisted storage contains only the generated-id server (and server order/jump references may disagree). This is disproven if the store guarantees these unawaited operations complete synchronously before `migrateIds()` returns, or if provider construction is serialized behind them.

In lib/core/utils/monitor_exec.dart, address this finding:
Cancelling a monitor-agent shell call only abandons the HTTP wait; it does not stop the command on the remote host. `MonitorExec.run` returns an apparently cancelled empty result after `cancel`, while the request continues until the monitor's independent timeout. Thus a reviewed state-changing command (for example an install, migration, or `rm`) can continue and complete after the user presses Stop, even though the Agent reports `Command cancelled`; this violates cancellation semantics and can also leave remote work/resource usage running after the conversation has moved on.

In monitor/frontend/src/lib/api.ts around line 94, address this finding:
Explicit per-entry capability/status requests do not handle expired credentials or network failures according to the API contract: `getCapabilitiesFor` and `getStatusFor` throw a generic error for 401/non-2xx and let fetch rejection escape as a raw TypeError, without clearing that entry's stale token or normalizing to `ApiError` with status.

In monitor/frontend/src/lib/api.ts around line 66, address this finding:
A 401 from an in-flight request can log out the wrong server after the user switches servers. `request()` captures `servers.current` for the URL/token, but on an unauthorized response it calls the unqualified `servers.logout()`, which clears whatever entry is current at response time. For example, a slow poll to server A returns 401 after the user selects server B; B's valid token is deleted and the UI is forced back to login even though B was never rejected. This is introduced by the new multi-server request/session handling; it would be disproven if server selection were guaranteed not to change for the lifetime of every request. Logout needs to be scoped to the entry/id used for the request (and ideally only if its token is still the same).

In monitor/frontend/src/lib/api.ts around line 87, address this finding:
The explicit per-entry status/capabilities helpers do not implement the auth and network error contract that the shared request path does. `getStatusFor()` and `getCapabilitiesFor()` call `fetch()` without a catch and never handle 401, so an expired token for a sidebar/name entry is left in `sessionStorage` and the entry remains authenticated; every name refresh/capability retry keeps using the dead bearer instead of clearing that session or surfacing an `ApiError` with its HTTP status. This is observable when an agent expires/revokes a token while the panel is open, and would be false only if these helpers were never used after token expiry or another layer explicitly converted 401s and removed the entry (their callers only catch and retain the old state).

In lib/data/model/file/transfer_worker.dart around line 234, address this finding:
Disposing a transfer does not cancel its queued prompt callback. `mainMessageHandler` always awaits `PromptQueue.shared.add(...)` and then sends a response, with no disposed/generation check; if a transfer is cancelled while its host-key or keyboard-interactive question is waiting behind another dialog, the callback still runs later and can display a prompt for the already-dead transfer. Its response is sent to a killed isolate, while the shared queue remains occupied until the user answers or the prompt timeout expires.

In lib/core/utils/server.dart around line 863, address this finding:
Forgetting a host key can be undone by an already queued host-key persistence write.

In lib/data/store/cached_store.dart around line 92, address this finding:
A legacy JSON record can fail an immediate update after fetch: _getAndConvert returns the decoded item but schedules putRaw unawaited, so have(old) still calls get<T> and returns null until that write completes. Any provider update invoked in that window throws 'Old ... not found' even though fetch exposed the record, and the provider/persistence state remains unchanged.

In lib/data/provider/private_key.dart around line 37, address this finding:
Adding a private key with an ID already present appends a second entry to Riverpod state while Hive stores only one record under that ID. The editor allows arbitrary name input and PrivateKeyNotifier.add constructs [...state.keys, info] without checking identity; the next reload collapses the duplicate, so the UI and persisted state diverge until reload and one logical key is silently replaced.

In lib/core/utils/server_dedup.dart around line 19, address this finding:
ServerDeduplication.deduplicateServers compares each imported server only with the pre-existing list, not with already accepted imports. Two identical servers in one import therefore both survive deduplication; importServersWithNotification then calls addServer twice, producing duplicate IDs in serverOrder and duplicate live-state entries (or overwriting the same Hive record).

In lib/data/model/app/bak/backup.dart around line 74, address this finding:
Legacy remote inheritance silently fails for a valid old backup whose `lastModTime` is absent or zero, which is precisely a supported shape (`Backup.lastModTime` is nullable). `inheritLegacyRemote` calls `merge()` without force, and `Backup.merge` computes `shouldRestore = force || curTime < bakTime`; on a fresh store `Stores.lastModTime` is 0 and a legacy file with null/0 has `bakTime` 0, so it logs 'local is newer' and imports none of the servers/snippets/keys/etc. The subsequent code still logs the inheritance attempt as successful. This is introduced/exposed by the new legacy migration path; it would be disproved if every legacy backup ever written is guaranteed to contain a strictly positive `lastModTime` and fresh initialized stores always report a value greater than zero.

In lib/data/provider/private_key.dart around line 53, address this finding:
`PrivateKeyNotifier.update` can delete the newly written key when the old record is absent and both objects have the same id. In the `idx == -1` branch it awaits `Stores.key.put(newInfo)` and then unconditionally awaits `Stores.key.delete(old)`; `delete` keys by id, so a stale provider state or an external deletion causes the replacement just written to be removed. The update/delete tests do not exercise this stale-store case. This would be disproved if callers could guarantee that `idx == -1` implies `old.id != newInfo.id` (or that the old store entry always exists).

In lib/view/page/private_key/edit.dart around line 289, address this finding:
Private-key save failures are rethrown after only a toast, so an invalid PEM/decryption failure becomes an unhandled asynchronous exception rather than a contained UI error. `_onTapSave` catches the isolate error, calls `Toast.error`, then `rethrow`; because the FAB callback is not awaited by Flutter, the page gets no error dialog and the exception is reported as an uncaught future error. The same pattern can occur for persistence failures after validation.

In lib/data/provider/ai/agent_session.dart, address this finding:
Continuing a persisted conversation does not preserve the conversation's provider/model metadata: every Agent request reads the current global settings, and each save overwrites the stored providerBaseUrl/model with those settings. If a user changes endpoint or model after creating a conversation, the next turn is sent to the new model with the old transcript and the record is rewritten, so replay/continuation no longer has the metadata it was created under.

In lib/data/provider/ai/agent_session.dart around line 544, address this finding:
Persistence has the same stale-identity race even without a late stream event. _persist captures the current conversation, awaits save, and then unconditionally assigns state.conversation/history from that saved record. A completed turn sets isStreaming false before awaiting _persist, so activateConversation can restore another conversation during that await; when the old save returns it replaces the newly selected state with the old turn. The same issue exists after tool execution/decline because those methods also await _persist after clearing their working flag.

In lib/data/provider/ai/agent_session.dart around line 406, address this finding:
Stopping a streamed turn is not durable. stopWork cancels the subscription and appends an interrupted notice only to state.timeline, but does not append a corresponding assistant/history item or call _persist. After restart or switching away and reopening the conversation, the persisted user prompt has neither a response nor an interruption marker, so replay presents the turn as an unresolved conversation and can leave the protocol history inconsistent with what the user saw.

In lib/data/provider/ai/ask_ai.dart around line 771, address this finding:
The JSON replay serializer forwards orphan function outputs even though replay treats them as unmatched: `_chatMessages` emits every `AskAiFunctionOutputItem` as a `role: tool` message without checking that a preceding serialized function call with the same ID exists. A restored/old conversation containing a raw or declined/tool-result item whose call was trimmed or not persisted (or an output with a typo in `call_id`) produces a Chat Completions request rejected for an invalid tool message instead of replaying the usable remainder. This would be false only if storage migration guarantees every output always has its matching call and trimming can never leave an orphan.

In monitor/install.sh, address this finding:
The default systemd user install attempts enable/restart before ensuring a user systemd manager exists, so headless installs commonly fail to start or enable the service.

In monitor/frontend/src/lib/serverNames.svelte.ts around line 61, address this finding:
Live server names remain cached after logout, removal, or URL replacement and can be displayed for a different unauthenticated/reused server entry.

In monitor/src/core/config.rs around line 625, address this finding:
Invalid push rate values such as `0/0s` are accepted and silently disable or effectively remove the intended rate limit.

In monitor/src/ssh/local_pty.rs around line 135, address this finding:
Local shell startup leaks an orphan shell when PTY setup fails after spawning the child

In monitor/frontend/src/lib/servers.svelte.ts around line 146, address this finding:
The live server-name cache is not invalidated when an entry is logged out or its URL is changed, so the sidebar can continue displaying the previous agent's name for an unauthenticated/different server indefinitely.

In monitor/src/core/config.rs around line 441, address this finding:
Environment configuration does not consistently take precedence over a TOML file: when `config.toml` contains a `[server]` section, `get_server()` returns that section verbatim, so `SBM_HOST`, `SBM_PORT`, and `SBM_TLS_CERT`/`SBM_TLS_KEY` are ignored (the same variables are only consulted by `ServerConfig::default()` when the entire section is absent). A deployment that keeps a normal `[server]` section and changes `SBM_PORT` therefore continues listening on the old port, while the documented/configuration contract says environment is the primary channel and the CLI code only treats explicit `--addr` as the override. This is introduced/exposed by the new partial-default/precedence arrangement in `Config::get_server` and `apply_env_overrides`, which only applies JWT and CORS. It would be false if the intended contract were that these server environment variables apply only when `[server]` is absent, contrary to the environment documentation and `ServerConfig::default` comments.

In monitor/src/api/server.rs around line 792, address this finding:
`PUT /api/v1/settings` accepts zero for both optional runtime cadence fields even though the UI and configuration semantics require a positive interval. A request with `extended_interval_secs: 0` persists zero; `effective_extended_interval_secs()` returns it unchanged, and `is_extended_cycle` then divides by `interval_seconds` and clamps the resulting cadence to 1, causing the expensive extended script to run every core cycle. Likewise `idle_pause_threshold_secs: 0` makes `should_run_extended` false whenever idle-pause is enabled, so extended collection is effectively disabled after the first elapsed second. The endpoint validates only `interval_seconds`, and the TOML deserializer also accepts these values. This would be false only if zero were deliberately documented as a supported alias for “every cycle”/“always pause”; the frontend uses `min="1"`, comments describe unset/null—not zero—as the default, and the resulting behavior is not exposed as such.

In test/agent_view_test.dart around line 78, address this finding:
The Agent history-column breakpoint test does not actually test the narrow 700px layout because its helper changes only the test surface, not the view size reported through MediaQuery. `AgentPage` delegates the split decision to `AdaptiveSideList`, whose adaptive width logic uses the view/media-query dimensions; therefore the `width: 700` case can still be laid out at the default 1200px test view and pass `findsFalse` without exercising the narrow branch. This leaves the changed responsive Agent widget coverage unreliable.

In .github/workflows/analysis.yml around line 78, address this finding:
PRs changing Android native sources (and other unlisted platform/build workflow files) can receive no relevant analysis job: the changes filter only treats analysis.yml, pubspec, packages, Dart/test, Rust, iOS, and selected scripts as coverage. For example, a change to android/app/src/main/AndroidManifest.xml makes rust/ish/dart/frontend/docs/website all false, while build.yml does not run on pull_request.

In .github/workflows/analysis.yml around line 80, address this finding:
Changes to build.yml, macos.yml, monitor-release.yml, dependabot/configuration, or other workflow files do not invalidate the change-aware analysis filters unless analysis.yml itself changes. A PR can therefore modify release permissions, artifact naming, matrices, or monitor CI replacement and have every expensive analysis job skipped.

In lib/data/provider/ai/ask_ai.dart, address this finding:
Persisted conversation metadata does not control replay requests: restoring a conversation records `protocol`, `provider_base_url`, and `model`, but `AgentSession.startStream` passes only the history and protocol, while `AskAiRepository.ask` always rereads the current settings for base URL and model. After the user changes provider/model settings, continuing an old conversation therefore sends its old transcript to the new model/endpoint, and `_persist` then overwrites the conversation metadata with the new settings. This is false only if these fields are intentionally audit-only and switching provider/model for an existing conversation is explicitly supported.

In lib/data/provider/server/monitor_http.dart around line 496, address this finding:
Disposal does not reliably terminate a concurrent login: `dispose()` clears `_loginFuture`, but an already-running `_loginImpl` can resume afterward, call `_session()`, restore `_token` and the Authorization header, and recreate the Dio session after disposal.

In lib/core/service/watch_sync.dart around line 247, address this finding:
Watch-token revocation for an endpoint change can leave the old token active: `_revokeServer` uses the old endpoint from application context but copies the current monitor username/password. If the monitor credentials were changed along with the endpoint (or the old endpoint has different credentials), revocation fails and the old scoped token remains valid until expiry.

In ios/WatchApp/MonitorClient.swift around line 58, address this finding:
Replacing a server entry leaks the old watch-side URLSession: `shared(for:)` overwrites `cache[server.id]` when the value changes but never calls `invalidateAndCancel()` on the discarded client/session, leaving its connection pool and in-flight work alive.

In lib/data/model/file/copy_tree.dart around line 148, address this finding:
Inline cancellation is not checked after a file's write completes, so a cancellation during the final chunk can still publish a successful transfer and leave the destination replaced. `runCopy` checks cancellation before each chunk, but after the stream finishes it immediately awaits `dest.write(...)` and then returns; `_runHere` emits `finished` without another check. A one-file local/monitor transfer cancelled after its last chunk but before `write` resolves therefore completes despite `_disposed`, unlike the documented cancellation behavior.

In lib/core/utils/server.dart around line 197, address this finding:
A successful ProxyJump connection leaks the jump SSH client for the entire lifetime of the app (and often beyond the target session).

In lib/data/provider/ai/global_agent_tools.dart around line 1508, address this finding:
Stop/timeout cancellation does not cancel monitor-backed server operations. cancelCurrent only completes _cancelRun, which is installed by _runShell; serverbox connect/refresh instead awaits refresh().timeout(_operationTimeout) with no cancellation signal. If a monitor request hangs, pressing Stop returns without stopping it, and the underlying refresh can later mutate server connection/status after the Agent turn was stopped (and after the UI/conversation may have changed).

In lib/view/page/ssh/page/ask_ai.dart around line 296, address this finding:
The SSH Ask AI panel still implements an independent conversation/stream/tool state machine instead of consuming the app-scoped AgentSession. It owns _history, _conversation, _subscription, pending command, execution and persistence, while the global Agent uses the separate __global_agent__ conversation. Opening the SSH Agent and the global Agent therefore shows different sessions and can run/approve concurrently; a turn started in one view is not visible or stoppable from the other, violating the required app-wide session contract.

In lib/data/model/ai/ask_ai_models.dart around line 633, address this finding:
`AskAiCommandResult.tryFromToolMessage` classifies any JSON object containing either `stdout` or `stderr` as a successful tool-result record, without requiring a result discriminator, types for the fields, or the expected command/call identity. Consequently a provider/tool output such as `{"stdout":"model-generated text"}` (or a stored raw output from an older schema) is rendered as an execution result and is not shown as an untrusted notice; replay can therefore claim a command has a result when no executor produced one. This is false only if the tool-output boundary guarantees that every such JSON object is exclusively app-generated and old/raw outputs cannot reach this parser.

In monitor/install.sh around line 398, address this finding:
The default systemd user install cannot bootstrap on hosts without an already-running per-user manager

In lib/core/service/watch_sync.dart, address this finding:
Expired watch tokens are reused indefinitely, so a watch configured for more than 90 days eventually becomes permanently unable to load metrics until the server address changes or the selection is recreated.

In lib/data/provider/server/monitor_http.dart, address this finding:
Disposal can be undone by an in-flight login. If `dispose()` runs while `_loginImpl()` is awaiting `/login`, dispose clears `_dio` and `_loginFuture`; when the login completes, `_loginImpl` assigns `_token` and calls `_session()`, which creates a new Dio because `_dio` was nulled. The supposedly disposed client therefore resurrects a live HTTP session (and leaves it unclosed), and a caller awaiting the original operation can continue using it. This is false only if callers can prove dispose never overlaps a login request.

In lib/core/service/watch_sync.dart, address this finding:
Watch-token revocation uses the current monitor credentials even when revoking a token issued for an earlier credential. `_revokeServer` constructs the client with `monitor.user`/`monitor.pwd` from the current Spi while using only the old endpoint from application context. If the monitor password/user changes and the server is then removed or its endpoint changes, login at the old endpoint fails and `/watch-token` is never reached; the old read-only token remains valid for up to the agent's 90-day lifetime. This would be disproved only if monitor credentials are immutable for the lifetime of every watch token or the server invalidates those tokens on credential changes.

In lib/view/page/backup.dart, address this finding:
The backup page can write to a disposed loading notifier after its route is removed during an in-flight operation. For example, `_onTapWebdavDl` awaits WebDAV listing, a file picker, download, and restore; if the page is popped during any await, `dispose()` runs `webdavLoading.dispose()`, and the unconditional `finally { webdavLoading.value = false; }` then updates the disposed notifier (the analogous Gist/WebDAV upload paths have the same pattern). This is a likely teardown-time exception and there is no widget test that disposes the page while one of these async callbacks is pending. The claim would be false if the notifier implementation explicitly permits writes after disposal or the operation is guaranteed to cancel before route disposal.

In monitor/src/core/config.rs, address this finding:
Environment host/port/TLS overrides are ignored whenever a TOML file contains a [server] section (including the generated default config).

In monitor/src/ssh/local_pty.rs, address this finding:
Local PTY startup can leave the newly spawned shell orphaned when take_writer or try_clone_reader fails.

In monitor/src/db/cleanup.rs, address this finding:
A zero cleanup interval can crash the cleanup task at startup instead of being rejected or safely disabled. `start_cleanup_scheduler` converts `cleanup_interval_hours` directly to a Tokio interval period; `Duration::from_secs(0)` is passed to `tokio::time::interval`, which panics because a zero period is invalid. The settings endpoint validates `interval_seconds` but does not validate any `data_retention` fields, and config deserialization/defaults likewise permit zero, so an authenticated settings update (or a hand-edited config) can set `cleanup_interval_hours = 0`; this leaves retention/size cleanup unavailable and can produce a task panic. This would be false only if another config-validation layer guarantees the value is always >=1 before scheduler construction.

• ⚠️ The normal phone-side WatchSync path rejects non-HTTPS/non-loopback HTTP monitor endpoints before issuing a token, so exploiting this through an unmodified current phone configuration is not expected; the watch-side boundary still accepts and uses arbitrary persisted or received WatchServer values, including stale data and tampered/corrupt payloads.

In ios/WatchApp/MonitorClient.swift, address this finding:
The watch sends bearer watch tokens to any URL in its stored/pushed `WatchServer`, without enforcing HTTPS or loopback HTTP. `get` constructs a URL and sets Authorization before `send`, and `loadLegacy` also accepts arbitrary URLs (though legacy is unauthenticated). A malicious/corrupt WatchConnectivity payload or stale insecure monitor configuration can therefore leak the scoped token over plaintext HTTP.

Renaming a private key to the ID of another existing key can delete/replace the wrong identity. `PrivateKeyNotifier.update` delegates to `CachedHiveStore.update`, which writes the new ID (overwriting any key already stored there) and then removes the old ID; the editor allows any non-empty name and performs no collision check. A rename from A to B therefore destroys B's key and leaves servers referencing B with the renamed A material.

Invalidate cached tokens after unpair revocation.

Lines 102-104 revoke the selected tokens but retain their application-context token pairs. After the watch pairs again, buildPayload() can reuse the revoked token when the endpoint is unchanged. The watch then cannot authenticate.

After successful revocation, remove or durably mark the token pair as revoked. The next paired push must issue a replacement token.

• 🟡 Medium The watch accepts payloads with an unsupported/future version instead of enforcing the payload-version contract. (inline)
• 🟡 Medium When the phone is unpaired, revocation is best-effort only in logging but failure leaves selected watch credentials active, and the loop aborts on the first failed server. (inline)
• 🟡 Medium Expired scoped tokens are reused indefinitely because reuse checks only normalized endpoint, not token validity or expiry. After the 90-day agent lifetime, any push that sees the old application context emits the expired token again and the watch remains unauthorized until some unrelated endpoint change causes rotation. (inline)

⛔ Unresolved from previous review (34) — not approved until fixed

• lib/data/model/app/bak/backup.dart: The legacy Backup reader accepts a future v1 payload version without rejecting it. Backup.fromJson delegates directly to generated deserialization, and MergeableUtils falls back to this reader after the V2 reader fails; a future/unsupported legacy-shaped file can therefore be partially decoded and merged instead of raising SchemaTooNewException, losing fields or deleting local records according to the incomplete payload. — The legacy reader is unchanged: Backup.fromJson still delegates directly to generated deserialization and does not compare json['version'] with backupFormatVersion. MergeableUtils only rethrows SchemaTooNewException from BackupV2; its V2 format version is newer than the legacy version, so a legacy-shaped payload with a version greater than 1 but within the V2-supported range can make V2 parsing fail and then be accepted by Backup.fromJson, allowing the incomplete legacy payload to merge.
• lib/core/utils/sftp_file_backend.dart: SFTP backend writes are not actually bounded by the configured operation timeout: after the staged file is opened, file.write(...).done is awaited directly. A stalled SFTP upload (including server-side backpressure or a lost channel that leaves the future pending) can therefore leave a server-to-server or monitor/SFTP copy running forever even though SftpFileBackend was constructed with _prepareTimeout(job). This is false only if the dartssh2 write future is independently guaranteed to complete or fail on every such stalled connection.
• .github/workflows/monitor-release.yml: The monitor release matrix sets SQLX_OFFLINE=true but the repository has no monitor/.sqlx offline query cache, while the monitor contains sqlx::query! macros. A clean release run therefore fails during compilation with offline query-cache errors before producing native packages or the Docker image.
• monitor/src/core/config.rs: DATABASE_URL is ignored on the normal TOML loading path when the file omits database_url: Config::load deserializes the file and get_database_url() falls back directly to sqlite:serverbox_monitor.db, rather than consulting the environment. Thus a deployment with a valid config.toml (for example one containing only [server]/[monitoring]) and DATABASE_URL=/persistent/monitor.db silently opens the local default database, risking a fresh database and loss of the expected history/users. DATABASE_URL is consulted only by Config::default() and legacy normalization, so the behavior differs based solely on whether a TOML file exists. This would be false only if DATABASE_URL were intentionally supported exclusively for first-run/legacy migration, which conflicts with the documented environment configuration and the Docker/systemd use case.
• Filesystem confinement is bypassable through a symlink swap between validation and use — The current implementation still performs a check-then-use on path names: resolve_existing canonicalizes and confines the path, returns a PathBuf, and handlers subsequently use that path with ordinary filesystem operations (for example tokio::fs::File::open(&path) in read). A symlink or parent directory can still be swapped after canonicalization and before the open/read (and the module explicitly acknowledges this TOCTOU), so the previously described escape remains possible.
• lib/data/provider/ai/global_agent_tools.dart: Local read_file has the same TOCTOU escape after confinement: _localPath resolves the target and verifies it is under the root, then _readLocalFile creates a new File from the original host string and performs exists, length, and reads later. A symlink can be swapped after validation, so the read can follow an outside target and return host/app secrets despite the rootfs boundary.
• lib/data/model/ai/ask_ai_models.dart: read_file is classified as read-only and is therefore eligible for unattended execution on any configured server, regardless of the path or sensitivity of the file. A model can propose read_file for /etc/shadow, a private key, cloud credentials, or application secrets with safe_to_run: true; canAutoRun is true and runPendingTool executes it without review, then puts the contents into the model conversation. Read-only does not mean non-sensitive, so this bypasses the stated review boundary for data access.
• lib/core/utils/local_exec.dart: The global shell output cap is applied only after ServerExec.run returns, but ProcessExec.run accumulates the complete stdout and stderr in unbounded StringBuffers before returning. A reviewed local command such as yes can therefore grow memory without bound (and can OOM the app) even though _runShell uses _BoundedTextAccumulator; the bounded callbacks do not prevent this second accumulation.
• lib/data/provider/ai/agent_session.dart: Conversation switching does not invalidate the old stream callbacks. restoreConversation only calls cancel(); _handleEvent and the subscription's onError/onDone have no stream or conversation generation check. If a provider emits an already-delivered event after the user activates another conversation (or an async _handleEvent resumes after the switch), the old completion/delta is applied to the newly restored state, and _persist() saves that mixed history. The old turn can therefore appear in and be written to the newly selected conversation despite the selection change. — The conversation switch still only cancels the subscription and replaces state; it does not invalidate callbacks already queued or callbacks whose async _handleEvent execution resumes later. _handleEvent, onError, and onDone still update the current state without checking that they belong to the stream/conversation that was active when they were registered, and _handleEvent still awaits _persist() after mutating that state. Thus an old completion or delta can still be applied to the newly restored conversation and persisted there.
• lib/view/page/private_key/edit.dart: Renaming a private key to the ID of another existing key can delete/replace the wrong identity. PrivateKeyNotifier.update delegates to CachedHiveStore.update, which writes the new ID (overwriting any key already stored there) and then removes the old ID; the editor allows any non-empty name and performs no collision check. A rename from A to B therefore destroys B's key and leaves servers referencing B with the renamed A material.
• lib/view/page/private_key/edit.dart: Saving a new private key with an existing name overwrites the existing key without a conflict check, while the notifier appends a second in-memory entry. The editor constructs PrivateKeyInfo(id: name, ...) and calls add; the store key is id, so put replaces the old PEM, and PrivateKeyNotifier.add builds [..., info] rather than rejecting the duplicate. Servers referring to that key ID therefore start using a different private key, and the key UI can show duplicate rows.
• lib/core/sync.dart: A failed read of an encrypted remote backup can still cause the sync cycle to overwrite that remote with the local snapshot. For example, when the saved password is wrong (or decryption fails for a transient/corrupt payload), fromFile catches the error at the generic handler, retries the raw encrypted text through the legacy reader, and then throws again; the too-new guard is never set. The base sync implementation is documented here as catching merge failures and uploading unconditionally, while backup only refuses when _remoteTooNew is set, so the remote encrypted data is replaced by the older/incomplete local copy. This is introduced by the new fallback/guard arrangement; it would be disproved if the base sync implementation never uploads after a fromFile/merge exception or if all decryption failures are converted to _remoteTooNew/an equivalent upload-blocking state.
• lib/view/page/backup.dart: A bulk server import can overwrite existing servers and leave the live provider/order state stale. — The bulk-import loop only deduplicates IDs among the imported records; it does not check existing server IDs. For an imported non-empty ID already in the store, spiWithId retains that ID and Stores.server.put(spiWithId) overwrites the persisted row directly. The code still does not update serverProvider/serversProvider state or reconcile serverOrder, so the live provider can continue exposing the previous server configuration and order state can remain stale.
• lib/data/model/file/transfer_status.dart: Cancelling immediately after creating a status can fail to stop the transfer at all. The constructor starts _initWorker() unawaited; dispose() kills/disposes the worker, but _initWorker() has no disposed check and, after its await resumes, calls worker!.init() and then worker.sendMessage(job) unconditionally. Thus a cancel-before-init-completes race can recreate/start the worker after the row is removed, leaving an orphan transfer and SSH client that the user can no longer cancel or observe.
• lib/data/model/file/transfer_worker.dart: The optimized local-to-SFTP upload has no transfer/idle timeout after opening the remote staging file. writer.done is awaited directly, while job.timeoutSeconds is used only for session/file-open and final rename; a server that stops accepting upload data can leave the transfer isolate alive indefinitely (and retain the remote staged file until it is killed). This is false only if SftpFile.write(...).done has an independent bounded-progress timeout in dartssh2, rather than merely completing when the peer responds.
• lib/data/model/file/transfer_worker.dart: Each transfer isolate starts its own staging counter at zero, so concurrent workers can choose the same staging pathname for the same destination. Their writes then truncate and overwrite one another, and cancellation cleanup by one worker can delete the other worker's in-progress staging file.
• lib/core/service/watch_sync.dart: Watch tokens are reused without considering their server-issued expiry, so a watch that remains configured for more than 90 days never receives a replacement token and stays unauthorized indefinitely. — reusableTokens still reuses any stored token whose endpoint matches, without reading an expiry. The payload only stores addr and token, while issueWatchToken returns expires_at but the Dart client discards it; therefore a configured watch can keep sending the same 90-day-expired token indefinitely unless another event causes a replacement.
• ios/WatchApp/MonitorClient.swift: The watch sends bearer watch tokens to any URL in its stored/pushed WatchServer, without enforcing HTTPS or loopback HTTP. get constructs a URL and sets Authorization before send, and loadLegacy also accepts arbitrary URLs (though legacy is unauthenticated). A malicious/corrupt WatchConnectivity payload or stale insecure monitor configuration can therefore leak the scoped token over plaintext HTTP.
• File uploads can be replayed after consuming a one-shot stream when the server returns 401: fsWrite calls _authed, whose 401 branch logs in and invokes fn() again with the same Stream<List<int>>. The second Dio request cannot read a single-subscription File.openRead stream and the upload fails (or can produce an incomplete write). — The current fsWrite pre-login only ensures authentication before the first request; it still executes the upload inside _authed. If that PUT receives a 401, _authed clears the token, logs in, and invokes fn() again. That closure still supplies the same Stream<List<int>> data, so a single-subscription File.openRead stream can still be re-listened after the first attempt and fail or upload incompletely.
• A failed read of an encrypted remote backup other than SchemaTooNewException does not set the upload-abort guard. fromFile catches the decryption/parse error, retries the payload without a password, and rethrows if that fails; _remoteTooNew remains null, so the subsequent SyncIface cycle can upload the local older backup over the unreadable remote and destroy remote-only data. — The generic catch (e, s) still logs and retries MergeableUtils.fromJsonString(content) without a password, but it does not set _remoteTooNew before that fallback. If the fallback also throws (the encrypted payload cannot be read), the exception propagates while _remoteTooNew remains null; backup() then calls super.backup(rs) because its guard only checks _remoteTooNew, so the unreadable remote can still be overwritten.
• Browser TOFU is raceable across simultaneous connections that start with separate cache snapshots. genClient copies the global store into hostKeyCache before constructing each verifier; two connections that see no pin can both prompt, and if they receive different offered keys, promptHostKeyExclusively merely serializes the dialogs rather than re-reading or atomically claiming the pin. Each verifier then writes its own key and returns true, while the serialized persistence queue eventually leaves whichever key was persisted last. Thus both a legitimate key and a concurrent impostor can be accepted during first use, and the second prompt is shown as isMismatch: false instead of comparing against the first winner. This would be proven false only if all concurrent genClient calls are guaranteed to share one mutable cache or the underlying SSH callback cannot concurrently offer different keys. — The defect remains. genClient still creates an isolated snapshot with Map<String, String>.from(knownHostFingerprints ?? _loadKnownHostFingerprints()), and HostKeyVerifier retains that map for the connection. promptHostKeyExclusively only waits for the prior dialog to finish; it does not re-read the persisted store or share/atomically update the verifier cache. Consequently, simultaneous first-use verifiers can each see existing == null, receive different keys, be prompted sequentially with isMismatch: false, and each accept and persist its own key.
• SFTP overwrite can permanently delete the good destination when the replacement rename fails after the fallback removal. _replace removes path and then performs a second rename without restoring or retaining the old file; any permission, quota, disconnect, or other error on that second rename leaves neither the old destination nor the new file. This violates FileBackend.write's atomic replacement/integrity contract for servers without the POSIX rename extension. — The current SftpFileBackend._replace still executes await _bounded('remove', _sftp.remove(path)); followed by await _bounded('rename', _sftp.rename(staging, path)); with no backup, rollback, or preservation of the destination. A failure in that second rename can therefore still leave neither the old destination nor the staging file. The analogous _replaceRemote helper in transfer_worker.dart has the same remove-then-rename sequence.
• monitor/install.sh: Upgrading from a malformed or incomplete package can permanently remove the working frontend and migrations and still report success. SBM_INSTALL_PKG is accepted after checking only the binary, while install_files deletes the existing frontend and migrations before copying those package paths; because the script does not use set -e or check the cp results, missing paths leave the service running without its panel/migrations and upgrade prints success.
• lib/core/sync.dart: The newer-schema refusal is not scoped to the sync attempt and can be bypassed by an overlapping sync, allowing an older copy to overwrite a newer remote file. fromFile clears the singleton marker at the start of every read, while backup later consults the shared marker; for example, sync A reads a too-new remote and yields after setting _remoteTooNew, sync B starts/reads any ordinary remote and clears it, then A reaches backup and uploads. The same singleton is used by automatic sync callers, so this is not limited to a UI double-tap. This is introduced by the static marker-based refusal design; it would be false only if SyncIface.sync serialized all calls globally and no other fromFile could run before the first call's backup decision. — The current BakSyncer still uses the shared static _remoteTooNew: fromFile clears it before each read, records the exception only in its own catch, and backup later reads the same field to decide whether to upload. Therefore an overlapping sync can still clear the first sync's refusal before that sync reaches backup; no per-sync token/state or synchronization is present in lib/core/sync.dart to prevent the described overwrite.
• lib/data/model/file/transfer_worker.dart: Concurrent transfers to the same destination can reuse the same staging pathname and corrupt or delete each other's work.
• lib/data/provider/server/monitor_http.dart: The monitor backend treats FileBackend.write's optional size hint as an authoritative HTTP Content-Length. runCopy passes a listing/stat-derived size, but the interface explicitly says that value is only a hint and the source can change while it is being read. If the actual stream length differs, the agent's HTTP payload framing can terminate early or wait/fail instead of consuming the stream, so a valid copy can be rejected or committed with a truncated body; the monitor implementation does not validate the byte count before renaming. — The original framing defect remains: runCopy still passes the listing-derived item.size to MonitorFileBackend.write, which forwards it to MonitorHttpClient.fsWrite; fsWrite still sets 'content-length': ?size. Thus a non-null stale hint is still emitted as authoritative HTTP framing, while the agent merely consumes whatever body framing the HTTP layer provides and does not compare the received byte count with the hint before renaming. The null case is chunked, but that does not fix calls that supply a size.
• lib/data/model/file/transfer_worker.dart: The SFTP replacement fallback deletes the existing destination after any failed rename for which stat(path) succeeds, without establishing that the failure was caused by an existing destination. A permission, transport, or server-side rename failure can therefore turn a failed transfer into loss of the previously good destination, and the second rename can fail leaving neither file.
• lib/data/model/file/transfer_worker.dart: A download idle timeout races the still-running SFTP read: Future.any returns on the timeout, then the finally block closes the local file and later the SFTP resources while downloadFuture is not cancelled or awaited. The outstanding read can write to a closed file, produce unhandled errors, or continue consuming resources after the transfer has reported failure.
• lib/data/model/file/transfer_worker.dart: Specialized SFTP staging names are not unique across concurrent transfer isolates, so one transfer can overwrite or delete another transfer's in-progress staging file.
• lib/data/provider/pve.dart: TFA submission is not bound to the session generation that produced its challenge. submitTfaCode captures only _pendingTfaChallenge, then after awaits calls _loginWithTfaChallenge and performs _getRelease/list with only ref.mounted checks. If the user reconnects after the challenge dialog opens, the captured old challenge is sent through the replacement session and the result can set current state/auth headers or close/publish errors for the new generation.
• lib/core/utils/server.dart: A successful jump connection leaks the jump SSHClient and leaves it owning the forwarding transport with no lifecycle owner: the local variable is only closed in the catch path, while the successful path returns the forward channel and discards jumpClient. When the target client is later closed or the connection is disposed, there is no retained jump client to close, so the jump SSH session/socket can remain alive indefinitely. — The successful jump path still executes return await jumpClient.forwardLocal(ssh.ip, ssh.port); and then drops the only jumpClient reference. jumpClient?.close() remains exclusively in the catch block, so once forwarding succeeds there is still no retained owner or cleanup that closes the jump SSH client when the returned target client/socket is later closed.
• monitor/frontend/src/lib/api.ts: A late 401 from a previously selected server can log out the newly selected server. If a poll/request for A is in flight and the user switches to B before A responds, request() receives A's 401 but calls servers.logout(), whose implementation clears servers.current (now B), thereby deleting B's valid token and sessionStorage entry.
• DELETE /api/v1/fs/remove can delete the target of an in-root symlink instead of deleting the symlink itself. remove calls resolve_existing, which canonicalizes every symlink, and then calls symlink_metadata/remove_dir_all on that canonical target; for /srv/root/link -> /srv/root/important, a request for /srv/root/link becomes /srv/root/important and removes the target. This violates the handler's stated “a link is deleted, never followed” invariant and can turn a harmless shortcut deletion into destructive deletion of another in-root tree. The claim would be false if resolve_existing preserved the final directory entry (or if the target could not be removed by the resulting operation). — The defect remains: remove still calls resolve_existing(&body.path), and resolve_existing still applies std::fs::canonicalize, which follows the final symlink and returns the target path. The subsequent symlink_metadata and removal operation therefore operate on that canonical target, so an in-root link such as link -> important can still cause important (including its tree when recursive) to be removed rather than removing link itself.
• Removing a symlink removes its canonical target rather than the symlink entry itself, contrary to the endpoint's documented remove semantics; a link inside one configured root can therefore delete a file or directory in another configured root. — The remove handler still calls roots.resolve_existing(&body.path), and resolve_existing uses std::fs::canonicalize, which follows the final symlink and returns its target path. symlink_metadata is then applied to that already-canonical target, so remove_file/remove_dir_all can still delete the target rather than the symlink entry, including a target in another configured root.

⚠️ Unverified risks (2)

• Changing a server's ID to an ID already used by another server silently overwrites the destination in memory while the store update removes/replaces rows by key. newServers[newSpi.id] = newSpi discards the existing destination server from the provider state (and the durable update targets the same key), so editing one server can destroy an unrelated server record and its ordering identity. (lib/data/provider/server/all.dart)
• The per-server Ask AI runner buffers complete stdout and stderr with Stream.join() before applying the 32,000-character output limit. A command emitting an unbounded stream can retain all output until the five-minute timeout, exhausting memory and preventing the advertised output limit from protecting the process. (lib/view/page/ssh/page/ask_ai.dart)

📋 Additional findings from this change (not shown inline) (46)

• 🟠 High The alternate destination's user is ignored for key-based authentication. If the primary socket fails and alterUrl parses as deploy@backup:2222, the fallback socket is opened correctly but _authenticatedClient still sets username: ssh.user whenever a key is configured. (lib/core/utils/server.dart) — anchor-outside-diff
• 🟠 High SSH config imports can save a ProxyJump as a jump ID that can never resolve to a stored server, causing every connection through that imported host to fail with “jump servers not found.” _extractJumpHost returns the textual endpoint (for example user@bastion:2222) and parseConfig assigns it directly to SshCredential.jumpId, but genClient resolves jump candidates by comparing that value to Spi.id and fetching Stores.server.fetchOneRaw(jumpId). The editor also presents only servers whose IDs are selectable, so the imported textual value is not representable/repairable there. This would be false only if imported SSH configs are guaranteed to use jump values that are already exact app server IDs, which normal OpenSSH ProxyJump syntax does not provide. (lib/core/utils/ssh_config.dart) — anchor-outside-diff
• 🟠 High Stop cannot cancel most shared Agent tools: cancelCurrent only completes _cancelRun, which is installed by _runShell, so an executing read_file/write_file/ssh_connect/serverbox operation continues while the UI has no effective cancellation path and remains executing. (lib/data/provider/ai/global_agent_tools.dart) — anchor-outside-diff
• 🟠 High A configured-server read_file proposal can be auto-run without review. read_file is intrinsically readOnly and _unvettedFloor only raises risk when sessionId is non-null; therefore a model can set server_id to an already-configured server, safe_to_run=true, and shouldAutoRunAgentCommand permits SFTP access immediately, despite the tool exposing arbitrary absolute paths and potentially sensitive files. (lib/data/model/ai/ask_ai_models.dart) — anchor-outside-diff
• 🟠 High Cancellation can be lost while SSH command creation is awaiting: _cancelAiCommand sets _aiCommandCancelled=true when _aiCommandSession is still null, but _runAiCommand later unconditionally assigns the returned session and waits for it, allowing the command to execute after the user pressed Stop during client.execute(). (lib/view/page/ssh/page/ask_ai.dart) — anchor-outside-diff
• 🟠 High The per-server Ask AI command runner has no bounded output collection: it starts Utf8Decoder(...).bind(session.stdout).join() and the equivalent stderr join immediately, then applies the 32,000-character limit only after the session completes. A command that produces a large or unbounded stream can therefore grow two full in-memory strings until the five-minute timeout (and still retains all output produced before termination), defeating the advertised output limit and allowing a remote command to exhaust the app process memory. This would be disproven if the SSH stream implementation itself enforces a hard byte/character cap before these joins; the shown caller does not enforce one. (lib/view/page/ssh/page/ask_ai.dart) — anchor-outside-diff
• 🟠 High The panel's irreversible full-access disable can be undone by the configured environment override, so a successful disable does not remain enforced after restart. (monitor/src/core/remote_access.rs) — anchor-outside-diff
• 🟠 High The installer continues after failed file operations and can report a successful upgrade/install with a partially deleted or partially copied application. (monitor/install.sh) — anchor-outside-diff
• 🟠 High Running the installer as root with a crafted SUDO_USER/DOAS_USER value executes attacker-controlled shell text as root. (monitor/install.sh) — anchor-outside-diff
• 🟠 High Reaping a detached terminal session removes only its map entry; it never signals the shell driver to stop. Session owns the input Sender, while the driver task owns an Arc<Session> and waits on the matching Receiver, so removing the map leaves a Sender/Receiver cycle alive and the SSH/local shell can remain running indefinitely after detached_timeout. (monitor/src/api/ws/session.rs) — anchor-outside-diff
• 🟠 High Bulk server import writes directly to Stores.server but never updates serversProvider, server ordering/tags, or schedules a backup. The current server UI remains stale until an unrelated reload, and an enabled sync can upload a snapshot that omits the newly imported servers. Its uniqueness check also only tracks IDs in the import batch, so an imported ID can overwrite an existing server. (lib/view/page/backup.dart) — anchor-unreliable
• 🟠 High Detached terminal reaping removes the session entry without closing the session's input channel or terminating the child shell, allowing detached shells to survive indefinitely beyond the configured timeout. (monitor/src/api/ws/session.rs) — anchor-unreliable
• 🟡 Medium Legacy flat server JSON containing an imported IdentityFile loses that credential during migration because keyPath is not included in the lifted fields. (lib/data/model/server/server_private_info.dart) — anchor-outside-diff
• 🟡 Medium Jump failover does not apply the configured timeout to forwardLocal, so a reachable/authenticated jump whose channel-open stalls can block forever and never try the next candidate. (lib/core/utils/server.dart) — inline-budget
• 🟡 Medium The Ask AI SSE decoder buffers unbounded assistant text, reasoning text, and tool-call arguments for the entire response, with no output/token cap; receiveTimeout is only a five-minute wall-clock timeout. A compatible endpoint that continuously emits valid deltas (or a malformed/huge function-argument stream) can keep the request alive for five minutes while StringBuffers, emitted UI text, and eventually persisted conversation data grow without bound. Thus the repository's streaming path has no effective output limit and can cause excessive memory/storage use before timeout. This would be disproven if the HTTP client or all supported endpoint implementations enforce a strict response-size limit before _decodeSsePayloads; this code configures no such limit. (lib/data/provider/ai/ask_ai.dart) — anchor-unreliable
• 🟡 Medium Malformed persisted Agent tool-result data can crash the Agent view during replay instead of being rendered as a safe raw/malformed notice. (lib/view/page/agent/view.dart) — inline-budget
• 🟡 Medium The Gist and WebDAV settings dialogs put stored credentials directly into ordinary text inputs without obscuring them, so opening Backup settings displays the GitHub token and WebDAV password in clear text and permits shoulder-surfing/copying of secrets. (lib/view/page/backup.dart) — inline-budget
• 🟡 Medium Snippet deletion can leave provider state inconsistent with the durable store when the caller supplies an equal-name but otherwise stale Snippet instance. del filters using full object equality (s != snippet) but SnippetStore.delete deletes by the stable name key; the row is removed from SQLite while the stale row remains in state.snippets and its tags, until a later reload. (lib/data/provider/snippet.dart) — inline-budget
• 🟡 Medium Stopping an Agent stream only cancels the Dart subscription; the underlying Dio request is created without a CancelToken and is not cancelled when the subscription is cancelled. A user who presses Stop while the provider is waiting for a remote SSE response leaves the HTTP connection running until its receive timeout (up to five minutes), contrary to cancellation/resource-lifetime behavior and potentially allowing network activity after the UI says it stopped. (lib/data/provider/ai/ask_ai.dart) — inline-budget
• 🟡 Medium The WebDAV and GitHub token/password fields display stored credentials in clear text. (lib/view/page/backup.dart) — inline-budget
• 🟡 Medium A failed or cancelled asynchronous WebDAV/Gist operation can update a disposed loading notifier and attempt to use a dead page context. (lib/view/page/backup.dart) — anchor-unreliable
• 🟡 Medium Enabling automatic WebDAV or Gist sync can leave its spinner permanently active and the switch validator unresolved when sync throws. (lib/view/page/backup.dart) — inline-budget
• 🟡 Medium Snippet reload persistently marks the settings store changed on every load after an order has been applied. order is a newly fetched List, and the code uses order != Stores.setting.snippetOrder.fetch() (List identity), so the condition is true even when the contents are identical; it writes the same order on every build/reload. This advances the settings last-update timestamp and can make backup/sync treat a no-op startup/reload as a local user mutation, potentially winning conflict resolution. The claim is false only if the store's list fetch returns the identical List instance on both calls, contrary to the store's copy semantics. (lib/data/provider/snippet.dart) — inline-budget
• 🟡 Medium A watch update can revoke the watch's only valid token and then fail to publish the replacement, leaving the watch permanently unable to authenticate until a later successful push. For example, after a monitor address change, buildPayload detects the old endpoint, calls _revokeServer (deleting the old watch:<id> token), issues a new token, and _pushOnce then calls updateApplicationContext; if that context update fails (transient connectivity/WatchConnectivity error), the watch still holds the old payload but its token has already been revoked. The next push reads that stale context, sees the endpoint mismatch, revokes/rotates again, so the old watch remains broken until delivery succeeds. This would be false only if updateApplicationContext were guaranteed to succeed whenever token rotation/revocation succeeds. (lib/core/service/watch_sync.dart) — inline-budget
• 🟡 Medium Malformed persisted SSH entry fields can abort the entire restore loop instead of being skipped independently. _restoreTabs only guards the outer JSON decode and then force-casts tmuxSession to String? and tmuxWindow to int? after resolving the source; a valid list such as [{'sourceId':'srv-1','tmuxWindow':'bad'}, {'sourceId':'srv-2'}] throws on the first entry and never restores the second (and the exception escapes the post-frame callback). The claim would be false only if the store contract guarantees these fields are always correctly typed for every persisted record, including legacy/corrupt records, or an enclosing caller catches these casts. (lib/view/page/ssh/tab.dart) — inline-budget
• 🟡 Medium Malformed file-tab records are not tolerated per entry, and an explicitly server-kind record with no serverId is incorrectly restored as a local tab. _restore force-casts entry['path'] as String?, so a record like {'kind':'server','serverId':'srv-1','path':42} aborts restoration before later valid entries. Independently, final isLocal = entry['kind'] == _kindLocal || serverId == null treats {'kind':'server','path':'/tmp'} as local, silently changing the persisted source identity. This would be false only if all stored records are guaranteed typed and never contain a missing serverId for kind:'server', which conflicts with the stated malformed/unknown-entry tolerance requirement. (lib/view/page/storage/tab.dart) — inline-budget
• 🟡 Medium The Rust CI does not enforce the committed workspace lockfile, so a stale or tampered Cargo.lock can be silently rewritten/resolved on the runner and the tested dependency graph need not be the reviewed graph. (.github/workflows/analysis.yml) — inline-budget
• 🟡 Medium A systemd user install can fail to start on a headless/logged-out account because the script restarts the user unit before enabling lingering. (monitor/install.sh) — anchor-unreliable
• 🟡 Medium The exec timeout kills by dropping tokio::process::Child (kill_on_drop(true)) but does not wait/reap it. A command that runs past 60 seconds therefore leaves a killed Unix child unreaped (zombie) until an external reaper adopts it, and repeated timed-out requests can accumulate process-table entries. (monitor/src/api/exec.rs) — inline-budget
• 🟡 Medium Editing a server URL does not invalidate in-flight or cached identity-dependent state, so the old agent can overwrite/display state for the new URL. (monitor/frontend/src/lib/servers.svelte.ts) — inline-budget
• 🟡 Medium The path filter does not treat l10n.yaml or Makefile as Dart/build inputs. A future PR changing the localization generator configuration (for example changing output-dir, locale handling, or untranslated-message policy) or changing the make gen-l10n command will set changes.outputs.dart to false and skip the only flutter analyze/flutter test job; the workflow's shared pattern includes pubspec, packages, and the workflow itself, but not these files. Such a change can therefore merge without exercising the affected build/runtime path. (.github/workflows/analysis.yml) — inline-budget
• 🟡 Medium Host-key records keyed by a pre-migration server oldId are orphaned when migrateIds assigns the server a new id; host-key lookup uses only the new id and migrateIds never rewrites the known-host map, causing a previously trusted server to prompt again (and leaving the old trusted record invisible to the UI for that server). (lib/data/store/server.dart) — inline-budget
• 🟡 Medium A watch request can regress the durable application context to an older selection. _onWatchAsked builds a payload and launches updateApplicationContext unawaited; concurrently, push() can build and commit a newer payload, after which the older request's context write can complete last. The next activation then receives stale server entries even though the store has the newer selection. (lib/core/service/watch_sync.dart) — inline-budget
• 🟡 Medium dispose() is not safe against setup still awaiting isSupported: it clears _ready and returns, but the in-flight _setup() then assigns _wc, installs callbacks/subscriptions, and can later be used after disposal. A dispose during startup (or a hot lifecycle teardown) therefore resurrects a WatchConnectivity session and leaks its subscriptions. (lib/core/service/watch_sync.dart) — inline-budget
• 🟡 Medium stopLiveActivityOnAppClose can stop the Live Activity and then have a queued sync recreate/update it. _drainSync's finally starts a new drain whenever _syncDirty was set during the awaited sync, but stopLiveActivityOnAppClose awaits only the old _syncing future and never marks the manager closed or clears dirty state. A timer/callback that calls _sync() while the native stop is in flight can therefore schedule a second _updateLiveActivity after the app-close stop, leaving an orphaned activity or post-close native work. (lib/data/ssh/session_manager.dart) — inline-budget
• 🟡 Medium The service does not perform graceful shutdown under the init systems this installer configures: systemd/OpenRC send SIGTERM, but the runtime waits only for tokio's Ctrl-C (SIGINT) signal. (monitor/src/cli/cli.rs) — inline-budget
• 🟡 Medium The backup password tip tells users that leaving the field empty disables encryption, but the localized UI rejects an empty submission and only offers a separate Remove action when a password is already set. (lib/l10n/app_en.arb) — inline-budget
• 🟡 Medium Localization generation is not checked for reproducibility in CI: the workflow analyzes checked-in/generated Dart but never runs flutter gen-l10n and fails on a diff, so ARB and generated outputs can drift without detection. (.github/workflows/analysis.yml) — inline-budget
• 🟡 Medium The new CI reproducibility job does not verify that the checked-in localization sources and generated Dart are reproducible. A change to an ARB or l10n configuration can leave lib/generated/l10n/*.dart stale (or contain a hand-edited generated change), while flutter pub get/the build regenerates files in the runner and the only post-generation diff check covers pubspec.yaml and pubspec.lock. Thus CI can pass for a repository state whose checked-in generated localization is not what l10n.yaml produces, and consumers that compile/test the checkout without regeneration can see different locale behavior. (.github/workflows/analysis.yml) — inline-budget
• 🟡 Medium Stopping a streamed shared Agent turn records AgentNoticeKind.interrupted only in memory. stopWork never calls _persist, so closing/reopening or switching away and back loses the interruption notice and the persisted replay no longer reflects the visible timeline. (lib/data/provider/ai/agent_session.dart) — anchor-unreliable
• 🟡 Medium The remote backup handlers always write to the page-owned loading notifiers in finally, even if the page is unmounted while list/download/upload is awaiting. dispose disposes webdavLoading/gistLoading, so a cancellation/navigation during an in-flight operation can make the finally assignment target a disposed notifier and throw; similarly the auto-sync validators assign false after await bakSync.sync without checking mounted. Loading cleanup needs an unmount-safe owner or mounted guard. (lib/view/page/backup.dart) — anchor-unreliable
• 🟡 Medium A timed-out exec child is killed but not awaited, so repeated timeout requests can leave zombie processes until the monitor is reaped by its parent. (monitor/src/api/exec.rs) — anchor-unreliable
• 🟡 Medium Release discovery only requests the first 100 GitHub releases, so once the repository has more than 100 releases and the newest monitor release is outside that page, the installer reports no monitor release even though one exists. (monitor/install.sh) — anchor-unreliable
• 🟡 Medium Release discovery can fail to find an otherwise available monitor release once the repository has more than 100 releases, because it queries only the first GitHub API page and does not paginate or select a valid monitor asset across pages. (monitor/install.sh) — anchor-unreliable
• 🟡 Medium A 401 from an older request can log out the wrong server after the user switches selection. (monitor/frontend/src/lib/api.ts) — anchor-unreliable
• 🟡 Medium Capabilities are cached solely by entry ID and are never cleared when that entry's URL changes. servers.update() clears the token but leaves capabilitiesStore.byServer[id]; after logging into the replacement agent, ensure(id) returns early on the old capability object, so dashboard card gating, OS icon, and terminal availability can describe the old server. The issue is false only if server IDs are guaranteed never to be edited to point at another agent, which this update path explicitly permits. (monitor/frontend/src/lib/servers.svelte.ts) — anchor-unreliable

♻️ Previously reported (still present) (8)

• 🟠 High Known-host deletion can be undone by an already queued persistence operation. persistHostKeyFingerprint serializes writes in _hostKeyPersistence, but forgetHostKey/forgetHostKeyFingerprints directly write the setting without joining or invalidating that queue. If a user accepts a key (which queues prop.set), then deletes that key before the queued callback runs, the callback rereads the setting and adds its accepted fingerprint back, resurrecting trust; the next connection is silently trusted despite the user's deletion. (lib/core/utils/server.dart) — previously-reported

❓ Low-evidence leads (not confirmed — verify before acting) (2)

• A host-key prompt whose show callback throws synchronously permanently occupies the per-server prompt gate. (lib/core/utils/server.dart)
• The new watch payload still carries the legacy urls list alongside the authenticated servers list, and the updated watch parser unconditionally appends both. A migrated/retained legacy URL therefore appears as a duplicate server (one token-authenticated monitor entry plus one unauthenticated legacy entry), while the phone continues to preserve and emit that list. This makes the new watch UI show duplicate/stale entries and leaves the old unauthenticated path active for the same monitor. (ios/WatchApp/PhoneConnMgr.swift)

## Unresolved from the previous review — these block approval, fix them first (34)

In lib/data/model/app/bak/backup.dart, address this finding:
The legacy Backup reader accepts a future v1 payload version without rejecting it. Backup.fromJson delegates directly to generated deserialization, and MergeableUtils falls back to this reader after the V2 reader fails; a future/unsupported legacy-shaped file can therefore be partially decoded and merged instead of raising SchemaTooNewException, losing fields or deleting local records according to the incomplete payload.

In lib/core/utils/sftp_file_backend.dart, address this finding:
SFTP backend writes are not actually bounded by the configured operation timeout: after the staged file is opened, `file.write(...).done` is awaited directly. A stalled SFTP upload (including server-side backpressure or a lost channel that leaves the future pending) can therefore leave a server-to-server or monitor/SFTP copy running forever even though `SftpFileBackend` was constructed with `_prepareTimeout(job)`. This is false only if the dartssh2 write future is independently guaranteed to complete or fail on every such stalled connection.

In .github/workflows/monitor-release.yml, address this finding:
The monitor release matrix sets SQLX_OFFLINE=true but the repository has no monitor/.sqlx offline query cache, while the monitor contains sqlx::query! macros. A clean release run therefore fails during compilation with offline query-cache errors before producing native packages or the Docker image.

In monitor/src/core/config.rs, address this finding:
`DATABASE_URL` is ignored on the normal TOML loading path when the file omits `database_url`: `Config::load` deserializes the file and `get_database_url()` falls back directly to `sqlite:serverbox_monitor.db`, rather than consulting the environment. Thus a deployment with a valid `config.toml` (for example one containing only `[server]`/`[monitoring]`) and `DATABASE_URL=/persistent/monitor.db` silently opens the local default database, risking a fresh database and loss of the expected history/users. `DATABASE_URL` is consulted only by `Config::default()` and legacy normalization, so the behavior differs based solely on whether a TOML file exists. This would be false only if `DATABASE_URL` were intentionally supported exclusively for first-run/legacy migration, which conflicts with the documented environment configuration and the Docker/systemd use case.

Somewhere in the code under review, address this finding:
Filesystem confinement is bypassable through a symlink swap between validation and use

In lib/data/provider/ai/global_agent_tools.dart, address this finding:
Local `read_file` has the same TOCTOU escape after confinement: `_localPath` resolves the target and verifies it is under the root, then `_readLocalFile` creates a new `File` from the original host string and performs `exists`, `length`, and reads later. A symlink can be swapped after validation, so the read can follow an outside target and return host/app secrets despite the rootfs boundary.

In lib/data/model/ai/ask_ai_models.dart, address this finding:
`read_file` is classified as read-only and is therefore eligible for unattended execution on any configured server, regardless of the path or sensitivity of the file. A model can propose `read_file` for `/etc/shadow`, a private key, cloud credentials, or application secrets with `safe_to_run: true`; `canAutoRun` is true and `runPendingTool` executes it without review, then puts the contents into the model conversation. Read-only does not mean non-sensitive, so this bypasses the stated review boundary for data access.

In lib/core/utils/local_exec.dart, address this finding:
The global shell output cap is applied only after `ServerExec.run` returns, but `ProcessExec.run` accumulates the complete stdout and stderr in unbounded `StringBuffer`s before returning. A reviewed local command such as `yes` can therefore grow memory without bound (and can OOM the app) even though `_runShell` uses `_BoundedTextAccumulator`; the bounded callbacks do not prevent this second accumulation.

In lib/data/provider/ai/agent_session.dart, address this finding:
Conversation switching does not invalidate the old stream callbacks. `restoreConversation` only calls `cancel()`; `_handleEvent` and the subscription's `onError`/`onDone` have no stream or conversation generation check. If a provider emits an already-delivered event after the user activates another conversation (or an async `_handleEvent` resumes after the switch), the old completion/delta is applied to the newly restored `state`, and `_persist()` saves that mixed history. The old turn can therefore appear in and be written to the newly selected conversation despite the selection change.

In lib/view/page/private_key/edit.dart, address this finding:
Renaming a private key to the ID of another existing key can delete/replace the wrong identity. `PrivateKeyNotifier.update` delegates to `CachedHiveStore.update`, which writes the new ID (overwriting any key already stored there) and then removes the old ID; the editor allows any non-empty name and performs no collision check. A rename from A to B therefore destroys B's key and leaves servers referencing B with the renamed A material.

In lib/view/page/private_key/edit.dart, address this finding:
Saving a new private key with an existing name overwrites the existing key without a conflict check, while the notifier appends a second in-memory entry. The editor constructs `PrivateKeyInfo(id: name, ...)` and calls `add`; the store key is `id`, so `put` replaces the old PEM, and `PrivateKeyNotifier.add` builds `[..., info]` rather than rejecting the duplicate. Servers referring to that key ID therefore start using a different private key, and the key UI can show duplicate rows.

In lib/core/sync.dart, address this finding:
A failed read of an encrypted remote backup can still cause the sync cycle to overwrite that remote with the local snapshot. For example, when the saved password is wrong (or decryption fails for a transient/corrupt payload), `fromFile` catches the error at the generic handler, retries the raw encrypted text through the legacy reader, and then throws again; the too-new guard is never set. The base sync implementation is documented here as catching merge failures and uploading unconditionally, while `backup` only refuses when `_remoteTooNew` is set, so the remote encrypted data is replaced by the older/incomplete local copy. This is introduced by the new fallback/guard arrangement; it would be disproved if the base sync implementation never uploads after a `fromFile`/merge exception or if all decryption failures are converted to `_remoteTooNew`/an equivalent upload-blocking state.

In lib/view/page/backup.dart, address this finding:
A bulk server import can overwrite existing servers and leave the live provider/order state stale.

In lib/data/model/file/transfer_status.dart, address this finding:
Cancelling immediately after creating a status can fail to stop the transfer at all. The constructor starts `_initWorker()` unawaited; `dispose()` kills/disposes the worker, but `_initWorker()` has no disposed check and, after its await resumes, calls `worker!.init()` and then `worker.sendMessage(job)` unconditionally. Thus a cancel-before-init-completes race can recreate/start the worker after the row is removed, leaving an orphan transfer and SSH client that the user can no longer cancel or observe.

In lib/data/model/file/transfer_worker.dart, address this finding:
The optimized local-to-SFTP upload has no transfer/idle timeout after opening the remote staging file. `writer.done` is awaited directly, while `job.timeoutSeconds` is used only for session/file-open and final rename; a server that stops accepting upload data can leave the transfer isolate alive indefinitely (and retain the remote staged file until it is killed). This is false only if `SftpFile.write(...).done` has an independent bounded-progress timeout in dartssh2, rather than merely completing when the peer responds.

In lib/data/model/file/transfer_worker.dart, address this finding:
Each transfer isolate starts its own staging counter at zero, so concurrent workers can choose the same staging pathname for the same destination. Their writes then truncate and overwrite one another, and cancellation cleanup by one worker can delete the other worker's in-progress staging file.

In lib/core/service/watch_sync.dart, address this finding:
Watch tokens are reused without considering their server-issued expiry, so a watch that remains configured for more than 90 days never receives a replacement token and stays unauthorized indefinitely.

In ios/WatchApp/MonitorClient.swift, address this finding:
The watch sends bearer watch tokens to any URL in its stored/pushed `WatchServer`, without enforcing HTTPS or loopback HTTP. `get` constructs a URL and sets Authorization before `send`, and `loadLegacy` also accepts arbitrary URLs (though legacy is unauthenticated). A malicious/corrupt WatchConnectivity payload or stale insecure monitor configuration can therefore leak the scoped token over plaintext HTTP.

Somewhere in the code under review, address this finding:
File uploads can be replayed after consuming a one-shot stream when the server returns 401: `fsWrite` calls `_authed`, whose 401 branch logs in and invokes `fn()` again with the same `Stream<List<int>>`. The second Dio request cannot read a single-subscription `File.openRead` stream and the upload fails (or can produce an incomplete write).

Somewhere in the code under review, address this finding:
A failed read of an encrypted remote backup other than SchemaTooNewException does not set the upload-abort guard. fromFile catches the decryption/parse error, retries the payload without a password, and rethrows if that fails; _remoteTooNew remains null, so the subsequent SyncIface cycle can upload the local older backup over the unreadable remote and destroy remote-only data.

Somewhere in the code under review, address this finding:
Browser TOFU is raceable across simultaneous connections that start with separate cache snapshots. `genClient` copies the global store into `hostKeyCache` before constructing each verifier; two connections that see no pin can both prompt, and if they receive different offered keys, `promptHostKeyExclusively` merely serializes the dialogs rather than re-reading or atomically claiming the pin. Each verifier then writes its own key and returns true, while the serialized persistence queue eventually leaves whichever key was persisted last. Thus both a legitimate key and a concurrent impostor can be accepted during first use, and the second prompt is shown as `isMismatch: false` instead of comparing against the first winner. This would be proven false only if all concurrent `genClient` calls are guaranteed to share one mutable cache or the underlying SSH callback cannot concurrently offer different keys.

Somewhere in the code under review, address this finding:
SFTP overwrite can permanently delete the good destination when the replacement rename fails after the fallback removal. `_replace` removes `path` and then performs a second rename without restoring or retaining the old file; any permission, quota, disconnect, or other error on that second rename leaves neither the old destination nor the new file. This violates `FileBackend.write`'s atomic replacement/integrity contract for servers without the POSIX rename extension.

In monitor/install.sh, address this finding:
Upgrading from a malformed or incomplete package can permanently remove the working frontend and migrations and still report success. `SBM_INSTALL_PKG` is accepted after checking only the binary, while `install_files` deletes the existing `frontend` and `migrations` before copying those package paths; because the script does not use `set -e` or check the `cp` results, missing paths leave the service running without its panel/migrations and `upgrade` prints success.

In lib/core/sync.dart, address this finding:
The newer-schema refusal is not scoped to the sync attempt and can be bypassed by an overlapping sync, allowing an older copy to overwrite a newer remote file. `fromFile` clears the singleton marker at the start of every read, while `backup` later consults the shared marker; for example, sync A reads a too-new remote and yields after setting `_remoteTooNew`, sync B starts/reads any ordinary remote and clears it, then A reaches `backup` and uploads. The same singleton is used by automatic sync callers, so this is not limited to a UI double-tap. This is introduced by the static marker-based refusal design; it would be false only if `SyncIface.sync` serialized all calls globally and no other `fromFile` could run before the first call's backup decision.

In lib/data/model/file/transfer_worker.dart, address this finding:
Concurrent transfers to the same destination can reuse the same staging pathname and corrupt or delete each other's work.

In lib/data/provider/server/monitor_http.dart, address this finding:
The monitor backend treats `FileBackend.write`'s optional `size` hint as an authoritative HTTP Content-Length. `runCopy` passes a listing/stat-derived size, but the interface explicitly says that value is only a hint and the source can change while it is being read. If the actual stream length differs, the agent's HTTP payload framing can terminate early or wait/fail instead of consuming the stream, so a valid copy can be rejected or committed with a truncated body; the monitor implementation does not validate the byte count before renaming.

In lib/data/model/file/transfer_worker.dart, address this finding:
The SFTP replacement fallback deletes the existing destination after any failed rename for which stat(path) succeeds, without establishing that the failure was caused by an existing destination. A permission, transport, or server-side rename failure can therefore turn a failed transfer into loss of the previously good destination, and the second rename can fail leaving neither file.

In lib/data/model/file/transfer_worker.dart, address this finding:
A download idle timeout races the still-running SFTP read: Future.any returns on the timeout, then the finally block closes the local file and later the SFTP resources while downloadFuture is not cancelled or awaited. The outstanding read can write to a closed file, produce unhandled errors, or continue consuming resources after the transfer has reported failure.

In lib/data/model/file/transfer_worker.dart, address this finding:
Specialized SFTP staging names are not unique across concurrent transfer isolates, so one transfer can overwrite or delete another transfer's in-progress staging file.

In lib/data/provider/pve.dart, address this finding:
TFA submission is not bound to the session generation that produced its challenge. submitTfaCode captures only _pendingTfaChallenge, then after awaits calls _loginWithTfaChallenge and performs _getRelease/list with only ref.mounted checks. If the user reconnects after the challenge dialog opens, the captured old challenge is sent through the replacement session and the result can set current state/auth headers or close/publish errors for the new generation.

In lib/core/utils/server.dart, address this finding:
A successful jump connection leaks the jump SSHClient and leaves it owning the forwarding transport with no lifecycle owner: the local variable is only closed in the catch path, while the successful path returns the forward channel and discards jumpClient. When the target client is later closed or the connection is disposed, there is no retained jump client to close, so the jump SSH session/socket can remain alive indefinitely.

In monitor/frontend/src/lib/api.ts, address this finding:
A late 401 from a previously selected server can log out the newly selected server. If a poll/request for A is in flight and the user switches to B before A responds, `request()` receives A's 401 but calls `servers.logout()`, whose implementation clears `servers.current` (now B), thereby deleting B's valid token and sessionStorage entry.

Somewhere in the code under review, address this finding:
`DELETE /api/v1/fs/remove` can delete the target of an in-root symlink instead of deleting the symlink itself. `remove` calls `resolve_existing`, which canonicalizes every symlink, and then calls `symlink_metadata`/`remove_dir_all` on that canonical target; for `/srv/root/link -> /srv/root/important`, a request for `/srv/root/link` becomes `/srv/root/important` and removes the target. This violates the handler's stated “a link is deleted, never followed” invariant and can turn a harmless shortcut deletion into destructive deletion of another in-root tree. The claim would be false if `resolve_existing` preserved the final directory entry (or if the target could not be removed by the resulting operation).

Somewhere in the code under review, address this finding:
Removing a symlink removes its canonical target rather than the symlink entry itself, contrary to the endpoint's documented remove semantics; a link inside one configured root can therefore delete a file or directory in another configured root.

## Findings on this change (also posted as inline comments) (3)

In ios/WatchApp/PhoneConnMgr.swift around line 135, address this finding:
The watch accepts payloads with an unsupported/future version instead of enforcing the payload-version contract.

In lib/core/service/watch_sync.dart around line 102, address this finding:
When the phone is unpaired, revocation is best-effort only in logging but failure leaves selected watch credentials active, and the loop aborts on the first failed server.

In lib/core/service/watch_sync.dart around line 174, address this finding:
Expired scoped tokens are reused indefinitely because reuse checks only normalized endpoint, not token validity or expiry. After the 90-day agent lifetime, any push that sees the old application context emits the expired token again and the watch remains unauthorized until some unrelated endpoint change causes rotation.

## Additional findings on this change (not posted inline) (46)

In lib/core/utils/server.dart around line 323, address this finding:
The alternate destination's user is ignored for key-based authentication. If the primary socket fails and `alterUrl` parses as `deploy@backup:2222`, the fallback socket is opened correctly but `_authenticatedClient` still sets `username: ssh.user` whenever a key is configured.

In lib/core/utils/ssh_config.dart around line 112, address this finding:
SSH config imports can save a `ProxyJump` as a jump ID that can never resolve to a stored server, causing every connection through that imported host to fail with “jump servers not found.” `_extractJumpHost` returns the textual endpoint (for example `user@bastion:2222`) and `parseConfig` assigns it directly to `SshCredential.jumpId`, but `genClient` resolves jump candidates by comparing that value to `Spi.id` and fetching `Stores.server.fetchOneRaw(jumpId)`. The editor also presents only servers whose IDs are selectable, so the imported textual value is not representable/repairable there. This would be false only if imported SSH configs are guaranteed to use jump values that are already exact app server IDs, which normal OpenSSH ProxyJump syntax does not provide.

In lib/data/provider/ai/global_agent_tools.dart around line 781, address this finding:
Stop cannot cancel most shared Agent tools: cancelCurrent only completes _cancelRun, which is installed by _runShell, so an executing read_file/write_file/ssh_connect/serverbox operation continues while the UI has no effective cancellation path and remains executing.

In lib/data/model/ai/ask_ai_models.dart around line 381, address this finding:
A configured-server read_file proposal can be auto-run without review. read_file is intrinsically readOnly and _unvettedFloor only raises risk when sessionId is non-null; therefore a model can set server_id to an already-configured server, safe_to_run=true, and shouldAutoRunAgentCommand permits SFTP access immediately, despite the tool exposing arbitrary absolute paths and potentially sensitive files.

In lib/view/page/ssh/page/ask_ai.dart around line 135, address this finding:
Cancellation can be lost while SSH command creation is awaiting: _cancelAiCommand sets _aiCommandCancelled=true when _aiCommandSession is still null, but _runAiCommand later unconditionally assigns the returned session and waits for it, allowing the command to execute after the user pressed Stop during client.execute().

In lib/view/page/ssh/page/ask_ai.dart around line 137, address this finding:
The per-server Ask AI command runner has no bounded output collection: it starts `Utf8Decoder(...).bind(session.stdout).join()` and the equivalent stderr join immediately, then applies the 32,000-character limit only after the session completes. A command that produces a large or unbounded stream can therefore grow two full in-memory strings until the five-minute timeout (and still retains all output produced before termination), defeating the advertised output limit and allowing a remote command to exhaust the app process memory. This would be disproven if the SSH stream implementation itself enforces a hard byte/character cap before these joins; the shown caller does not enforce one.

In monitor/src/core/remote_access.rs around line 244, address this finding:
The panel's irreversible full-access disable can be undone by the configured environment override, so a successful disable does not remain enforced after restart.

In monitor/install.sh around line 17, address this finding:
The installer continues after failed file operations and can report a successful upgrade/install with a partially deleted or partially copied application.

In monitor/install.sh around line 134, address this finding:
Running the installer as root with a crafted SUDO_USER/DOAS_USER value executes attacker-controlled shell text as root.

In monitor/src/api/ws/session.rs around line 302, address this finding:
Reaping a detached terminal session removes only its map entry; it never signals the shell driver to stop. `Session` owns the input Sender, while the driver task owns an Arc<Session> and waits on the matching Receiver, so removing the map leaves a Sender/Receiver cycle alive and the SSH/local shell can remain running indefinitely after detached_timeout.

In lib/view/page/backup.dart, address this finding:
Bulk server import writes directly to `Stores.server` but never updates `serversProvider`, server ordering/tags, or schedules a backup. The current server UI remains stale until an unrelated reload, and an enabled sync can upload a snapshot that omits the newly imported servers. Its uniqueness check also only tracks IDs in the import batch, so an imported ID can overwrite an existing server.

In monitor/src/api/ws/session.rs, address this finding:
Detached terminal reaping removes the session entry without closing the session's input channel or terminating the child shell, allowing detached shells to survive indefinitely beyond the configured timeout.

In lib/data/model/server/server_private_info.dart around line 85, address this finding:
Legacy flat server JSON containing an imported IdentityFile loses that credential during migration because keyPath is not included in the lifted fields.

In lib/core/utils/server.dart around line 197, address this finding:
Jump failover does not apply the configured timeout to forwardLocal, so a reachable/authenticated jump whose channel-open stalls can block forever and never try the next candidate.

In lib/data/provider/ai/ask_ai.dart, address this finding:
The Ask AI SSE decoder buffers unbounded assistant text, reasoning text, and tool-call arguments for the entire response, with no output/token cap; `receiveTimeout` is only a five-minute wall-clock timeout. A compatible endpoint that continuously emits valid deltas (or a malformed/huge function-argument stream) can keep the request alive for five minutes while `StringBuffer`s, emitted UI text, and eventually persisted conversation data grow without bound. Thus the repository's streaming path has no effective output limit and can cause excessive memory/storage use before timeout. This would be disproven if the HTTP client or all supported endpoint implementations enforce a strict response-size limit before `_decodeSsePayloads`; this code configures no such limit.

In lib/view/page/agent/view.dart around line 76, address this finding:
Malformed persisted Agent tool-result data can crash the Agent view during replay instead of being rendered as a safe raw/malformed notice.

In lib/view/page/backup.dart around line 701, address this finding:
The Gist and WebDAV settings dialogs put stored credentials directly into ordinary text inputs without obscuring them, so opening Backup settings displays the GitHub token and WebDAV password in clear text and permits shoulder-surfing/copying of secrets.

In lib/data/provider/snippet.dart around line 77, address this finding:
Snippet deletion can leave provider state inconsistent with the durable store when the caller supplies an equal-name but otherwise stale Snippet instance. `del` filters using full object equality (`s != snippet`) but `SnippetStore.delete` deletes by the stable name key; the row is removed from SQLite while the stale row remains in `state.snippets` and its tags, until a later reload.

In lib/data/provider/ai/ask_ai.dart around line 81, address this finding:
Stopping an Agent stream only cancels the Dart subscription; the underlying Dio request is created without a CancelToken and is not cancelled when the subscription is cancelled. A user who presses Stop while the provider is waiting for a remote SSE response leaves the HTTP connection running until its receive timeout (up to five minutes), contrary to cancellation/resource-lifetime behavior and potentially allowing network activity after the UI says it stopped.

In lib/view/page/backup.dart around line 771, address this finding:
The WebDAV and GitHub token/password fields display stored credentials in clear text.

In lib/view/page/backup.dart, address this finding:
A failed or cancelled asynchronous WebDAV/Gist operation can update a disposed loading notifier and attempt to use a dead page context.

In lib/view/page/backup.dart around line 273, address this finding:
Enabling automatic WebDAV or Gist sync can leave its spinner permanently active and the switch validator unresolved when sync throws.

In lib/data/provider/snippet.dart around line 46, address this finding:
Snippet reload persistently marks the settings store changed on every load after an order has been applied. `order` is a newly fetched List, and the code uses `order != Stores.setting.snippetOrder.fetch()` (List identity), so the condition is true even when the contents are identical; it writes the same order on every build/reload. This advances the settings last-update timestamp and can make backup/sync treat a no-op startup/reload as a local user mutation, potentially winning conflict resolution. The claim is false only if the store's list fetch returns the identical List instance on both calls, contrary to the store's copy semantics.

In lib/core/service/watch_sync.dart around line 144, address this finding:
A watch update can revoke the watch's only valid token and then fail to publish the replacement, leaving the watch permanently unable to authenticate until a later successful push. For example, after a monitor address change, `buildPayload` detects the old endpoint, calls `_revokeServer` (deleting the old `watch:<id>` token), issues a new token, and `_pushOnce` then calls `updateApplicationContext`; if that context update fails (transient connectivity/WatchConnectivity error), the watch still holds the old payload but its token has already been revoked. The next push reads that stale context, sees the endpoint mismatch, revokes/rotates again, so the old watch remains broken until delivery succeeds. This would be false only if `updateApplicationContext` were guaranteed to succeed whenever token rotation/revocation succeeds.

In lib/view/page/ssh/tab.dart around line 432, address this finding:
Malformed persisted SSH entry fields can abort the entire restore loop instead of being skipped independently. `_restoreTabs` only guards the outer JSON decode and then force-casts `tmuxSession` to String? and `tmuxWindow` to int? after resolving the source; a valid list such as `[{'sourceId':'srv-1','tmuxWindow':'bad'}, {'sourceId':'srv-2'}]` throws on the first entry and never restores the second (and the exception escapes the post-frame callback). The claim would be false only if the store contract guarantees these fields are always correctly typed for every persisted record, including legacy/corrupt records, or an enclosing caller catches these casts.

In lib/view/page/storage/tab.dart around line 423, address this finding:
Malformed file-tab records are not tolerated per entry, and an explicitly server-kind record with no serverId is incorrectly restored as a local tab. `_restore` force-casts `entry['path'] as String?`, so a record like `{'kind':'server','serverId':'srv-1','path':42}` aborts restoration before later valid entries. Independently, `final isLocal = entry['kind'] == _kindLocal || serverId == null` treats `{'kind':'server','path':'/tmp'}` as local, silently changing the persisted source identity. This would be false only if all stored records are guaranteed typed and never contain a missing serverId for kind:'server', which conflicts with the stated malformed/unknown-entry tolerance requirement.

In .github/workflows/analysis.yml around line 149, address this finding:
The Rust CI does not enforce the committed workspace lockfile, so a stale or tampered Cargo.lock can be silently rewritten/resolved on the runner and the tested dependency graph need not be the reviewed graph.

In monitor/install.sh, address this finding:
A systemd user install can fail to start on a headless/logged-out account because the script restarts the user unit before enabling lingering.

In monitor/src/api/exec.rs around line 204, address this finding:
The exec timeout kills by dropping `tokio::process::Child` (`kill_on_drop(true)`) but does not wait/reap it. A command that runs past 60 seconds therefore leaves a killed Unix child unreaped (zombie) until an external reaper adopts it, and repeated timed-out requests can accumulate process-table entries.

In monitor/frontend/src/lib/servers.svelte.ts around line 142, address this finding:
Editing a server URL does not invalidate in-flight or cached identity-dependent state, so the old agent can overwrite/display state for the new URL.

In .github/workflows/analysis.yml around line 78, address this finding:
The path filter does not treat `l10n.yaml` or `Makefile` as Dart/build inputs. A future PR changing the localization generator configuration (for example changing `output-dir`, locale handling, or untranslated-message policy) or changing the `make gen-l10n` command will set `changes.outputs.dart` to false and skip the only `flutter analyze`/`flutter test` job; the workflow's `shared` pattern includes `pubspec`, packages, and the workflow itself, but not these files. Such a change can therefore merge without exercising the affected build/runtime path.

In lib/data/store/server.dart around line 81, address this finding:
Host-key records keyed by a pre-migration server oldId are orphaned when migrateIds assigns the server a new id; host-key lookup uses only the new id and migrateIds never rewrites the known-host map, causing a previously trusted server to prompt again (and leaving the old trusted record invisible to the UI for that server).

In lib/core/service/watch_sync.dart around line 341, address this finding:
A watch request can regress the durable application context to an older selection. `_onWatchAsked` builds a payload and launches `updateApplicationContext` unawaited; concurrently, `push()` can build and commit a newer payload, after which the older request's context write can complete last. The next activation then receives stale server entries even though the store has the newer selection.

In lib/core/service/watch_sync.dart around line 355, address this finding:
`dispose()` is not safe against setup still awaiting `isSupported`: it clears `_ready` and returns, but the in-flight `_setup()` then assigns `_wc`, installs callbacks/subscriptions, and can later be used after disposal. A dispose during startup (or a hot lifecycle teardown) therefore resurrects a WatchConnectivity session and leaks its subscriptions.

In lib/data/ssh/session_manager.dart around line 265, address this finding:
`stopLiveActivityOnAppClose` can stop the Live Activity and then have a queued sync recreate/update it. `_drainSync`'s `finally` starts a new drain whenever `_syncDirty` was set during the awaited sync, but `stopLiveActivityOnAppClose` awaits only the old `_syncing` future and never marks the manager closed or clears dirty state. A timer/callback that calls `_sync()` while the native stop is in flight can therefore schedule a second `_updateLiveActivity` after the app-close stop, leaving an orphaned activity or post-close native work.

In monitor/src/cli/cli.rs around line 161, address this finding:
The service does not perform graceful shutdown under the init systems this installer configures: systemd/OpenRC send SIGTERM, but the runtime waits only for tokio's Ctrl-C (SIGINT) signal.

In lib/l10n/app_en.arb around line 91, address this finding:
The backup password tip tells users that leaving the field empty disables encryption, but the localized UI rejects an empty submission and only offers a separate Remove action when a password is already set.

In .github/workflows/analysis.yml around line 303, address this finding:
Localization generation is not checked for reproducibility in CI: the workflow analyzes checked-in/generated Dart but never runs `flutter gen-l10n` and fails on a diff, so ARB and generated outputs can drift without detection.

In .github/workflows/analysis.yml around line 123, address this finding:
The new CI reproducibility job does not verify that the checked-in localization sources and generated Dart are reproducible. A change to an ARB or l10n configuration can leave `lib/generated/l10n/*.dart` stale (or contain a hand-edited generated change), while `flutter pub get`/the build regenerates files in the runner and the only post-generation diff check covers `pubspec.yaml` and `pubspec.lock`. Thus CI can pass for a repository state whose checked-in generated localization is not what `l10n.yaml` produces, and consumers that compile/test the checkout without regeneration can see different locale behavior.

In lib/data/provider/ai/agent_session.dart, address this finding:
Stopping a streamed shared Agent turn records AgentNoticeKind.interrupted only in memory. stopWork never calls _persist, so closing/reopening or switching away and back loses the interruption notice and the persisted replay no longer reflects the visible timeline.

In lib/view/page/backup.dart, address this finding:
The remote backup handlers always write to the page-owned loading notifiers in `finally`, even if the page is unmounted while list/download/upload is awaiting. `dispose` disposes `webdavLoading`/`gistLoading`, so a cancellation/navigation during an in-flight operation can make the finally assignment target a disposed notifier and throw; similarly the auto-sync validators assign `false` after `await bakSync.sync` without checking `mounted`. Loading cleanup needs an unmount-safe owner or mounted guard.

In monitor/src/api/exec.rs, address this finding:
A timed-out exec child is killed but not awaited, so repeated timeout requests can leave zombie processes until the monitor is reaped by its parent.

In monitor/install.sh, address this finding:
Release discovery only requests the first 100 GitHub releases, so once the repository has more than 100 releases and the newest monitor release is outside that page, the installer reports no monitor release even though one exists.

In monitor/install.sh, address this finding:
Release discovery can fail to find an otherwise available monitor release once the repository has more than 100 releases, because it queries only the first GitHub API page and does not paginate or select a valid monitor asset across pages.

In monitor/frontend/src/lib/api.ts, address this finding:
A 401 from an older request can log out the wrong server after the user switches selection.

In monitor/frontend/src/lib/servers.svelte.ts, address this finding:
Capabilities are cached solely by entry ID and are never cleared when that entry's URL changes. `servers.update()` clears the token but leaves `capabilitiesStore.byServer[id]`; after logging into the replacement agent, `ensure(id)` returns early on the old capability object, so dashboard card gating, OS icon, and terminal availability can describe the old server. The issue is false only if server IDs are guaranteed never to be edited to point at another agent, which this update path explicitly permits.

In lib/core/utils/server.dart around line 502, address this finding:
Known-host deletion can be undone by an already queued persistence operation. `persistHostKeyFingerprint` serializes writes in `_hostKeyPersistence`, but `forgetHostKey`/`forgetHostKeyFingerprints` directly write the setting without joining or invalidating that queue. If a user accepts a key (which queues `prop.set`), then deletes that key before the queued callback runs, the callback rereads the setting and adds its accepted fingerprint back, resurrecting trust; the next connection is silently trusted despite the user's deletion.

Expired scoped tokens are reused indefinitely because reuse checks only normalized endpoint, not token validity or expiry. After the 90-day agent lifetime, any push that sees the old application context emits the expired token again and the watch remains unauthorized until some unrelated endpoint change causes rotation.

Handle failures from the auto-refresh timer.

If refresh() throws, the Timer does not handle the returned Future. The error becomes unhandled while finally schedules the next timer. Catch and log the failure before rescheduling.

Move this action into the page action extension.

_clearAllSettings() is an action on _SettingsPageState. Place it in the extension on _SettingsPageState action section to keep widget build logic, actions, and utilities separated.

As per coding guidelines, lib/view/**/*.dart must split UI into Widget build, Actions, and Utils using extension on.

171-184: 🩺 Stability & Availability | 🟠 Major | ⚡ Quick win

Continue refreshing servers after an individual refresh fails.

If serverNotifier.refresh() throws at Line 176, the current worker exits. If the first four workers fail, every remaining server is skipped, and Future.wait rejects. Catch and log errors for each server inside the loop, then continue processing the queue. Preserve aggregate error reporting separately if callers require it.

Proposed fix

     Future<void> worker() async {
       while (next < serversToRefresh.length) {
         final entry = serversToRefresh[next++];
         final serverNotifier = ref.read(serverProvider(entry.key).notifier);
-        await serverNotifier.refresh();
+        try {
+          await serverNotifier.refresh();
+        } catch (e, s) {
+          Loggers.app.warning(

@GT-610 The current block is not a failed GitHub Actions workflow.

GitHub reports these active blockers for #1318:

• The pull request review decision is CHANGES_REQUESTED.
• The winnowl/review status check is still IN_PROGRESS.
• There are unresolved winnowl review threads.
• There is also one unresolved CodeRabbit thread about concurrent AgentSession.submitPrompt calls.

CodeRabbit’s latest review is COMMENTED, not CHANGES_REQUESTED. The completed CI checks are all successful.

The open high-severity winnowl findings include watch-token HTTPS validation, watch-token expiry rotation, and private-key name collision handling. GitHub will remain blocked until required review requirements are satisfied and any required winnowl/review check completes.

I could not confirm the exact branch-protection rules because GitHub returned HTTP 403 for that endpoint.
