Reviewer's GuideThis PR converts the GenOS roadmap and contributor documentation into a correctness‑ and evidence‑first program, adds an explicit engineering quality and limitations register, strengthens contribution/security workflows and issue templates, and makes minimal kernel changes to satisfy Clippy so CI can run the full test and QEMU boot matrix.

When contributors use this checklist to reproduce the pull-request workflow, it omits all three userspace release-profile commands enforced by the release-checks job in .github/workflows/ci.yml (runtime, init, and shell at lines 98–100). A contributor can therefore complete every listed item locally yet still fail CI; add those commands alongside the bootloader and kernel release checks.
Useful? React with 👍 / 👎.

Disable persisted checkout credentials before artifact upload.
make test runs repository-controlled build steps before this job uploads build/ files. Default checkout credentials remain in Git configuration. A changed build step can copy that credential into the uploaded evidence artifact. Set persist-credentials: false unless a later step requires Git authentication.

Link the required architecture proposal.
This ADR defines a durable release policy. docs/adr/README.md requires an architecture proposal before an ADR. Line 6 records None, so the decision has no traceable proposal or review record.
Open and link the proposal issue. Alternatively, document a specific exception to the ADR workflow.

Use item-level dead-code exceptions across these modules.
Each module-level allowance can hide future unused code that is unrelated to the documented legacy path.

As per PR objectives, strict linting and narrow lint exceptions are release-gate requirements.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Normalize URI schemes before classifying external links.
URI schemes are case-insensitive. HTTPS://example.com is currently resolved as a repository path and can fail the documentation job. Compare the target after case normalization.

Summary
This PR changes GenOS planning from a feature-count roadmap into a correctness-first engineering program and makes the current build and CI evidence match that policy.
It:
rust-toolchain.toml;Why
The previous roadmap marked several foundation stages complete even though material low-level risks remain. The previous
mainworkflow also stopped during Clippy, so workspace tests and QEMU never reported their results.A green check must prove an exact, inspectable claim. It must not imply that exception handling, page protections, memory rollback, concurrency, fuzzing, hardware support, or release readiness are complete when they are not.
GenOS may aim to outperform Linux or another system on selected workloads, but every comparison must name the metric, workload, configuration, baseline, variance, failures, and missing features. Universal superiority claims remain invalid.
Scope and reviewability
This is a larger-than-usual vertical slice because the project-status contract and its currently enforced evidence need to land together. Splitting it would leave either:
The branch contains four focused commits. The final fix commit groups the review findings, strict-build cleanup, CI enforcement, documentation alignment, and QEMU synchronization repair required to make this policy true on the same reviewable head.
Immediate technical gates introduced
iretqpath with normalized vector-specific exception entry.CR0.WP, SMEP, and SMAP instead of depending on firmware state.F0 through F7 remain open. This PR narrows F0 and F7 but does not claim the verified-reference-build level.
Source and build changes
The source changes are deliberately narrow:
TaskSnapshotSet::is_empty()and tests for both empty and populated snapshots;USER_SOCKET_PASSIVE_LISTENER_READYafter the passive listener is actually active, trigger the host client from that marker, retain every passive-handshake/stream assertion, and report separate marker/server/inbound failure states.No exception, paging, allocator, capability, storage-format, network-protocol, or hardware implementation is changed here. The passive TCP change corrects test orchestration and adds evidence; it does not weaken or bypass the network proof.
CI enforced now
The pull-request workflow currently runs five independent jobs:
genos_abi,xtask, the UEFI bootloader, kernel library, complete kernel binary, userspace runtime, init, and shell.cargo test --workspace.serial*.logevidence.Every checkout sets
persist-credentials: false. No current job needs Git authentication after checkout. The exact local command lists in README, CONTRIBUTING, and the PR template include every enforced check.Target fuzzing, generated unsafe inventory, scheduled repetition, physical-hardware testing, full release-image construction, signing, and branch-protection enforcement remain explicit future work.
Verification

2de3d8b9a1b620141e79e06a4269ba18f12cd3d1:The retained
genos-qemu-evidenceartifact is tied to the exact head commit and includes the serial logs and manifest. A green run proves this implemented workflow only; it does not close the remaining roadmap gates.Review focus
Please review:
Deliberately out of scope
This PR does not implement the exception, CPU-protection, allocator, concurrency, decomposition, production networking, cryptographic security, update, or physical-hardware gates. It makes those gaps explicit, orders them, and defines the evidence required to close each one.
