From 1127bbaa67acac6b9a36666706a5bbb29acce40b Mon Sep 17 00:00:00 2001 From: Zixuan Chen Date: Mon, 17 Aug 2026 21:22:00 +0800 Subject: [PATCH 01/20] perf(capture): skip menu bar and time-box the accessibility walk MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The AX walk was spending most of its nodes on the menu bar — measured 205/257 in Ghostty, 245/276 in Zed, ~170/1115 in Feishu — encrypted and stored every 10s tick with no consumer: digests collect text roles only and the store's text extraction asserts menus are chrome. Stub the AXMenuBar subtree instead of descending. The walk also had a node cap but no time bound, while every attribute read is synchronous IPC into the target app (system default timeout 6s per call): one wedged app could stall ticks unboundedly and lag the app the user is working in. Bound both sides: process-global 100ms messaging timeout at startup plus a 500ms whole-walk deadline that sets `truncated`, same as the node cap. Verified: build green; startup + JSON event protocol smoke-tested (TCC-denied context, so real-walk behavior needs a signed dev run). Groundwork for the input-events/T1-acts program (phase 0).

The frontmost app is polled (100 ms — latency, not exposure) because the main thread blocks in `readLine` and never services a run loop, so `NSWorkspace` notifications would not arrive; the helper also holds all audio until the daemon's list arrives, since an app in front before that cannot be judged. +- Input events: a listen-only `CGEventTap` on its own thread emits coalesced `input_events` batches — typing-burst counts (key codes classify command keys and never leave the callback), command keys (⌘-combos, Return/Tab/Esc), click/scroll targets resolved to element identity (coordinates dropped after resolution). Excluded apps and AfterRay itself are never recorded; fails closed before the daemon's list arrives, fails open (warning) when the tap cannot be created. See docs/input-events-and-t1-acts-plan.md. - AX walk costs are bounded: the `AXMenuBar` subtree is stubbed (menus were 80–90% of walked nodes in native apps; every consumer treats them as chrome; deliberately not `truncated`), and the walk is time-boxed — process-global 100ms `AXUIElementSetMessagingTimeout` at startup + 500ms whole-walk deadline → `truncated`, same as the 20k node cap. A fresh Electron app's first snapshot may time out once while it builds its AX tree; the next heartbeat recovers. - Requires **macOS 15** (`Package.swift:6`) while the rest of the app targets macOS 14 — intentional, not a bug. diff --git a/apps/AfterRayCaptureShim/Sources/AfterRayCaptureShim/main.swift b/apps/AfterRayCaptureShim/Sources/AfterRayCaptureShim/main.swift index dd140614..aeb30fe0 100644 --- a/apps/AfterRayCaptureShim/Sources/AfterRayCaptureShim/main.swift +++ b/apps/AfterRayCaptureShim/Sources/AfterRayCaptureShim/main.swift @@ -111,6 +111,8 @@ private struct Event: Encodable { var height: Int? var code: String? var message: String? + var inputRecords: [InputEventRecord]? + var droppedInputs: Int? enum CodingKeys: String, CodingKey { case event, kind, path, code, message @@ -121,6 +123,8 @@ private struct Event: Encodable { case requestId = "request_id" case displayId = "display_id" case width, height + case inputRecords = "events" + case droppedInputs = "dropped" } static func ready(display: SCDisplay) -> Self { @@ -164,6 +168,13 @@ private struct Event: Encodable { static let stopped = Self(event: "stopped") + static func inputEvents(_ records: [InputEventRecord], dropped: Int) -> Self { + var event = Self(event: "input_events") + event.inputRecords = records + event.droppedInputs = dropped > 0 ? dropped : nil + return event + } + init( event: String, kind: ArtifactKind? = nil, @@ -985,6 +996,16 @@ private final class ExcludedAudioGate: @unchecked Sendable { return foreground } + /// Verdict for input-event suppression: `nil` until the daemon's list + /// has arrived, or when the frontmost app is unknown — both fail closed, + /// the same startup posture the audio hold takes. + func excludedVerdict(for bundleId: String?) -> Bool? { + lock.lock() + defer { lock.unlock() } + guard let excluded, let bundleId else { return nil } + return excluded.contains(bundleId.lowercased()) + } + /// The daemon sends the list once at startup and again on every change. func setExcludedBundles(_ bundleIds: [String]) { let normalized = Set(bundleIds.map { $0.lowercased() }) @@ -1370,6 +1391,434 @@ private func captureScreen( } } +// MARK: - Input events (listen-only) +// +// CAP-005 discipline is enforced here, at the source (see +// docs/input-events-and-t1-acts-plan.md): plain keystrokes exist only as +// burst counts — key codes are read solely to classify command keys and never +// leave the tap callback; pointer coordinates live exactly as long as the +// element resolution they feed.

Place noise: `target_key` accepted url/document/window_title unfiltered, so Feishu's `native-resource://sdk/avatar?...` became the slot's `theme_key`, and its bundled `file:///Applications/Lark.app/.../en-US.html` became the run title and a `facts.top_documents` entry — `shorten_place` reduces that path to a plausible-looking `en-US.html`, which passed the label filters. Every place candidate now runs through one gate, `is_place_noise` (`is_chrome_noise` + `is_opaque_id` + the new `is_app_bundle_resource`), applied to the raw value *and* its shortened form, at all four call sites: `target_key`, `place_label`, and the `top_documents`/`top_urls` aggregation. A rejected candidate falls through to the next; with every candidate rejected the key degrades to the app-only form. Anchor frame: the day summary anchored on `moment_ids.first()`. On real data a slot's opening frame is the worst thumbnail available — a window that just gained focus dumps its whole sidebar into that one frame (1399 characters of navigation). `SlotCard` now carries `anchor_moment_id`, computed by the pure `anchor_frame_id` as the middle frame of the longest run (ties to the earliest run); the first moment only stands in for a card built without one. It lives on `SlotCard`, not `RunRow`, because a `RunRow` field pushes `TimelineEntry` past clippy's `large_enum_variant` threshold — and the piece's own row list gives the exact middle rather than an estimate. Verified: `cargo test -p afterray-store` green, 154 passed / 0 failed / 1 ignored, up from 145 at HEAD (three new tests here; the rest arrived with concurrent work in the same tree). New tests replay both real-world failures verbatim, the all-noise degradation, and a 3-run slot whose longest run sits in the middle. `cargo clippy -p afterray-store --all-targets -- -D warnings` still errors only on lints that a pristine HEAD copy reproduces identically; slot.rs keeps exactly its two pre-existing findings and gains none. `cargo check --workspace` clean. Updated `assemble_keeps_t1_only_slots_and_overlays_t2_titles`: its anchor assertion asserted only `is_some()` under the name "opening frame", so it now names and pins the new rule (middle frame of the longest run, `b` rather than `a`). Not verified: no run against a real vault or the app UI — the thumbnails this changes were judged from the recorded slot, not re-rendered.

Not exposed via SharedReadOnlyVault. Daemon: the InputEvents arm goes from log-only to run_store batch insert (target serialized verbatim — InputTargetRef gains Serialize so the store needs no second schema); prune runs beside enforce_retention. Verified: afterray-store 154/154; afterrayd 127 green plus only the pre-existing GOP compression-ratio failure; platform-macos 17/17; concurrency test 10/10 consecutive green via make test-repeat; zero clippy findings touching new code (the 114 workspace warnings are pre-existing nightly-pedantic noise, none mention new symbols). Implementation by an Opus subagent against the phase-2 contract in docs/input-events-and-t1-acts-plan.md; verification re-run and docs completed by the orchestrating session.

Keep the delete-after-capture ordering. The delete is logged and retried once; an AX snapshot that will not parse takes the same path, since an unnamed app cannot be checked. - **Audio exclusions cannot work that way** — a finished five-minute `m4a` cannot be sliced — so the bundle list is pushed to the shim (`push_audio_exclusions`, main.rs:1537 → `MacOsCaptureBackend::set_excluded_bundle_ids`) and the shim holds every sample until a foreground check vouches for the moment it arrived, dropping the rest (`ExcludedAudioGate`, main.swift:901). Audio is therefore never written and later cut — nothing unvouched-for reaches a file. +- Input events (`input_events` batches from the shim's listen-only tap) are persisted via `insert_input_events` into the `input_events` table — 48h retention (`prune_input_events`, run beside `enforce_retention`), cascaded by `delete_history`. - The pairing is load-bearing: the daemon evaluates exclusions **only** in the accessibility branch, so the shim must never emit a screen artifact without one (`main.swift:1157`). - Every sync `Vault` call from async code goes through `run_store` (`afterrayd` main, a `spawn_blocking` wrapper). Blocking a tokio worker on SQLite/encryption has historically frozen socket accepts and chat streams. The daemon also oversizes its Tokio worker pool (`2 × cores`, min 8) so UI accepts stay free under load. diff --git a/crates/afterray-platform-macos/src/lib.rs b/crates/afterray-platform-macos/src/lib.rs index f2b4251c..1f8668ae 100644 --- a/crates/afterray-platform-macos/src/lib.rs +++ b/crates/afterray-platform-macos/src/lib.rs @@ -154,19 +154,26 @@ pub struct InputEventRecord { /// The resolved identity of the element an input landed on. `label` is the /// element's title/description, never its value; `frame` is UI geometry in /// global top-left screen points, rounded — not a pointer coordinate. -#[derive(Debug, Clone, PartialEq, Eq, Deserialize)] +/// +/// `Serialize` exists so the daemon can store this shape verbatim in the +/// vault's `input_events.target_json`: the store deliberately does not model +/// element identity, and re-encoding it into a second schema on the way in +/// would be a second thing to keep in step with the shim.

The input-event join needs it: to say which region of a window a click landed in, the tree has to carry geometry. `memory.rs` gains a flattened, parent-linked arena — every question the join asks is an upward walk, which the nested shape makes a search — and `accessibility_text_lines` now delegates to the same traversal. That is the load-bearing part: the `AX_TEXT_MIN_CHARS` text-source decision counts the whole line vector and the join partitions that same vector, so the two must never be able to disagree about what a line is. `acts.rs` holds the geometry, pure: deepest node containing a landing point, LCA of several, expansion to the smallest ancestor covering ENGAGED_MIN_WINDOW_AREA_RATIO of its window — the single knob in the whole join. It fails open everywhere it cannot answer honestly: nothing landed, no window, an unmeasurable window frame all yield no scope, because an invented scope reads downstream as "the user was here".

Fixed shape, every field always serialised — a reader has to be able to tell "zero keys" from "keys unknown", and a missing field cannot. Two decisions worth the space: `ended_with` is not a submit. The shim emits both a burst carrying the key that closed it and a separate `command` row for that same key; counting both would double every Return in the slot, so only the command row counts. Pinned by a test. Run splitting is hysteretic. A new scope becomes a boundary only once sustained — two events or fifteen seconds — because triage (glancing at four conversations, answering one) otherwise shatters into four runs of one click each, which is how a real slot came out as "multi-group scan" with the actual 1:1 unmentioned. An un-promoted excursion folds back into the run it interrupted, where its clicked labels survive as the record of the glancing. An unresolved scope never forces a boundary: not knowing where an event landed is not evidence that it landed somewhere new. `unavailable` is not idle. A signal gap runs until input is observed again and no further, and no engaged assertion may be made inside it.

A slot with no input events has nothing to partition by and must come out byte-identical. Only the clock-derived fields are normalised — day and HH:MM are the card's one locale-dependent surface, and the fixture normalises both sides the same way. Everything the partition could plausibly break (line selection, ordering, line_frames, total_chars, more_chars, budgets) is pinned exactly.

Each run carries an `acts` block joined from the input stream, the text it introduced is split into the engaged region and the merely visible, and the card names the regions that received no input all slot. This is the fix for a measured failure: on a real Feishu slot, 67% of the prompt budget went to a conversation list the user never touched, and the card came out as "multi-group scan" with the actual 1:1 unmentioned. The engaged region now takes the whole existing budget through infoscore, so IDF de-chromes within the bucket that matters instead of ranking a sidebar against a conversation; peripheral text folds to 200 characters and a line count, because "40 lines, not shown" is what a model needs from it. Three things are load-bearing and each is pinned: The text-source gate still counts every line. `AX_TEXT_MIN_CHARS` decides AX-vs-OCR on the unfiltered vector, so a frame whose engaged pane is small keeps its exact accessibility text instead of being silently demoted to whole-screen OCR — which is the frame the join works best on. Fail-open is structural, not conventional. Partitioning is gated on the event stream itself, not on callers leaving `ax_join` unset, and the pinned fixture from 19ae9f8 still passes byte-for-byte. `unavailable` suppresses every engaged claim — including the partition itself. Splitting text into operated and visible is an assertion about agency, so a frame from a stretch the tap could not observe makes none, and no region is called untouched there. A run with an `ok` signal and zero acts is a fact, not a gap: "22 minutes here, no keys" can only be stated by a stream that was running, and the model is told the difference.

charset=UTF-8 Content-Transfer-Encoding: 8bit Two holes closed at the ends of the acts pipeline. The daemon was logging `input_tap_stalled` / `input_tap_unavailable` and throwing them away. A dead tap has to be recorded *in* the event stream, because T1 reads an absence of events as "the user did nothing here" — the one inference this pipeline exists to prevent. The marker rides the same table as a `signal_gap` row; the vault stores `kind` uninterpreted, so this needed no schema change and the gap arrives in its place in time. Events are deleted after 48 hours and T1 is computed lazily, so acts that are not frozen simply vanish from history: two days on, a card would keep the half that says what was on screen and silently lose the half that says what the user did. The sweeper now freezes sealed slots into `slot_summaries.acts_json`, and `slot_card` reads the frozen copy once the events are gone. The freeze runs before the T2 gate and independently of it. It is a short read and one small write with no model in it, and the deadline it races is physical — the events expire whether or not the machine was ever on AC power with a charged battery. Gating it behind T2's conditions would lose acts on exactly the laptops that stay unplugged. What the frozen copy deliberately does not restore is the engaged/peripheral partition: it was computed by hit-testing rects that no longer exist, so the text goes back to whole rather than being partitioned against a guess. Pinned, along with the roundtrip through expiry, the idempotence the five-minute sweeper needs, and the delete_history cascade.

The article carries the four invariants that may not be weakened (fail-open byte-for-byte, the text-source gate, `unavailable` suppressing every engaged claim, T1 purity), the measurements behind the 0.10 knob and the hysteresis, and the reason `ended_with` is not counted as a submit. The plan doc records what phase 3 did *not* do, which matters more than what it did: timeline rows are still cut by `target_key` rather than re-cut by engaged scope, only the v2 system prompt changed, and the facts.apps acts summary and revisits/theme_key rework are untouched. Also the two places the implementation came out stricter than the contract, both because a test forced it.

R3 fills exactly that hole: a candidate (frontmost bundle change, or a click), a 500ms settle window that any further input re-arms, and a token bucket of >=5s spacing and <=6 walks per rolling minute. The pacing rules are a pure state machine in `AfterRayCapturePolicy` (`EdgeSnapshotPacing`) because both failure modes — walking the tree while the user is still typing, and walking it thirty times a minute — are invisible to any test that needs a live `CGEventTap`. Never a screenshot: an event-driven frame would outlive the events that triggered it and keep exposing interaction instants after the record of the interaction was erased. Two v1 simplifications, per the plan: the walk root is the whole AXWindow the trigger landed in (focused window fallback) rather than the engaged subtree, and known browsers are skipped entirely, because the heartbeat's private-browsing gate needs an async automation probe a 1s worker tick cannot afford.

Pruning deletes the encrypted files, not just the rows. `delete_history` gains a fourth layer — frames, cards, acts, and now R3 trees. Nothing else could have reached them: they belong to no moment. Artifacts have no purpose column, so the purpose rides the content type (`purpose=edge-ax`). It is a constant, never a string copied off the capture event: the encryption AAD binds the content type, so an artifact stored under one spelling and read back under another is undecryptable.

It stores the tree as an encrypted `edge-ax` artifact plus one `edge_snapshots` row: no moment, no thumbnail, no OCR job — an edge snapshot is not a frame of the screen. The exclusion check is the accessibility branch's, one notch stricter: `edge_snapshot_identity` refuses a snapshot that does not name its app, because the exclusion list is keyed by bundle identifier and an unnamed app cannot be judged. The heartbeat branch has a screenshot already on disk and must decide what to delete; this one loses nothing by dropping — the next trigger is one interaction away. That decision is a pure function so the fail-closed posture is testable without an AppState. Edge retention runs at the events' own call site, from the same clock.

It contributes no moment_id, no anchor, no OCR evidence and no `facts` count — those all answer "which frames does this card stand on", and an edge tree is not one. Pinned by a test that diffs every one of them against the same card built without edges. Two deliberate limits. The join does not write resolved scopes back onto the events from an edge tree: run splitting segments on those scopes, and R3's job is to widen the text a run shows, not to re-cut the runs. And a tree landing in a capture gap belongs to no run and is dropped, rather than being attached to the nearest one — that would claim a window was on screen during a stretch nothing was captured in. Edge trees are gated on the event stream like the partition itself, so the fail-open pin extends to them: a slot with edge trees and no events produces the byte-for-byte pre-acts card. It cannot hold them by construction — only input triggers a walk — and now a card cannot depend on that staying true.

Why: [acts-join](../../context/acts-join.md). - AX walk costs are bounded: the `AXMenuBar` subtree is stubbed (menus were 80–90% of walked nodes in native apps; every consumer treats them as chrome; deliberately not `truncated`), and the walk is time-boxed — process-global 100ms `AXUIElementSetMessagingTimeout` at startup + 500ms whole-walk deadline → `truncated`, same as the 20k node cap.

A landing point that coarse drags the run's engaged scope up to the window through the LCA, which re-creates the sidebar-noise bug this branch removes — and does it exactly when the user is typing, the strongest evidence of engagement there is. Bursts and command keys now fall back to the last click, which resolved to a real element (measured depth 21–39). The rule is a role decision, never an application one, and lives in the pure policy target as `TypingTarget` with five tests. **The 48h expiry rode the screen-import path**, so it only ran while recording. Stop capture and the raw click targets and R3 trees stayed on disk indefinitely, contradicting the contract. Expiry is a promise about time: it now runs inside `enforce_retention` — above its size-sweep early return, which fires whenever the vault is under its limit — so a mere `Vault::open` expires them, and on the sweeper's ungated tick beside `freeze_slot_acts`, which already exists because the same deadline is physical. A test opens a vault with nothing recorded and asserts the expired row is gone. **A failed event batch vanished silently.** A stretch with no rows reads as "the user did nothing", the one thing this pipeline may never say by accident, so a failed insert now writes a `signal_gap` marker spanning the batch. Extracted `record_signal_gap` so the dead-tap path and this one cannot drift. Also: the shim only stopped its monitor on the explicit `stop` command, so a daemon crash closing the pipe lost the events buffered since the last tick; `stop()` is idempotent and now runs on both exits. **Not changed: the reported pointer-coordinate flip.** The claim was that `CGEvent.location` is bottom-left origin and must be flipped for `AXUIElementCopyElementAtPosition`. Measured instead of assumed: a null-source `CGEvent` reports the cursor at y=562.6 while `NSEvent.mouseLocation` — documented bottom-left — reports y=554.4 on a 1117pt screen, summing to exactly the screen height. The two spaces are mirrors, so `CGEvent.location` is already top-left, like AX. Flipping it would have introduced the very bug the review was trying to prevent. Verified: afterray-store 218/218, shim XCTest 29/29, afterrayd 128 pass. Two afterrayd failures are pre-existing and reproduce with these changes stashed: the GOP compression-ratio assertion, and a live-Ollama stream test that asks a local model to echo a token (this session swapped the loaded model while running experiments).

Clicking around one such app burned all six walks and starved every other app for the minute. Spending now happens only through `fire(nowMs:walk:)`, which consumes the budget after the walk reports it happened; the permission check and the accounting are no longer separately callable, because an API that asks callers to pair them is one that eventually drifts. **Unavailable spans were closed at both ends.** A gap ends at the next observed input — the very event proving the tap was alive again — so that instant was being reported as unobservable. Spans are half-open now. A gap that never recovered still covers its horizon inclusively, which is why that fallback is one past the end rather than the end. **Materialisation missed slots that a span only reached into.** The work list was keyed on `at_ms` alone, so a burst from 09:59:58 to 10:00:20 enqueued only the first slot; with nothing else in the second one it was never frozen, and once the events expired it failed open forever — silently dropping typing the user did. Every slot a span touches is enqueued. The test was checked against the unfixed function first: it fails there, so it tests what it claims to. Also trimmed the duplicated rationale on `lastClick` now that `TypingTarget` owns that rule, and recorded the half-open span and the touched-slot rule in context/acts-join.md (invariant six). Verified: afterray-store 219/219, shim XCTest 30/30 (the three pacing tests now exercise the same `fire` path production does, plus a new one pinning that twenty declined walks leave the budget untouched), Swift root 340/340. afterrayd unchanged at 128 pass with the two pre-existing failures (GOP compression ratio; a live-Ollama stream test).

The frontmost app is polled (100 ms — latency, not exposure) because the main thread blocks in `readLine` and never services a run loop, so `NSWorkspace` notifications would not arrive; the helper also holds all audio until the daemon's list arrives, since an app in front before that cannot be judged. -- Input events: a listen-only `CGEventTap` on its own thread emits coalesced `input_events` batches — typing-burst counts (key codes classify command keys and never leave the callback), command keys (⌘-combos, Return/Tab/Esc), click/scroll targets resolved to element identity (coordinates dropped after resolution).

A fresh Electron app's first snapshot may time out once while it builds its AX tree; the next heartbeat recovers. - Requires **macOS 15** (`Package.swift:6`) while the rest of the app targets macOS 14 — intentional, not a bug. diff --git a/apps/AfterRayCaptureShim/Sources/AfterRayCapturePolicy/EdgeSnapshotPacing.swift b/apps/AfterRayCaptureShim/Sources/AfterRayCapturePolicy/EdgeSnapshotPacing.swift index 592f6f89..f4ba5b99 100644 --- a/apps/AfterRayCaptureShim/Sources/AfterRayCapturePolicy/EdgeSnapshotPacing.swift +++ b/apps/AfterRayCaptureShim/Sources/AfterRayCapturePolicy/EdgeSnapshotPacing.swift @@ -53,6 +53,12 @@ package struct EdgeSnapshotPacing: Equatable { /// otherwise fire seconds later against a screen that has moved on, and the /// snapshot would be attributed to a trigger it no longer describes.
