Full details: Docstring CoverageExplanation Docstring coverage is 97.62% which is sufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff. Analyzed 42 functions across 13 files. (8 skipped: 8 unsupported.) Full details: Testing (Overall)Explanation The new Skylos tests are substantive. They cover the strict scan recipe, whitelist validation and argument forwarding, and Makeutil provisioning in the full-suite workflows. However, the pull request also changes the public Resolution Add a Makeutil-parsed Makefile contract test for Full details: User-Facing DocumentationExplanation Pass this check. Treat the PR as developer-facing maintenance, not new end-user action functionality. The changed action internals do not alter the documented inputs or outputs: Full details: Developer DocumentationExplanation The pull request documents the new Skylos architecture and Makeutil requirements in Resolution Update Full details: Module-Level DocumentationExplanation Pass the module-level documentation check. Every Python module changed by the pull request has a module docstring, including the new Skylos contract test module. The changed test and pipeline modules also document their purpose and component relationships where needed. The only syntax-parsing anomaly is pre-existing in Full details: Testing (Unit And Behavioural)Explanation Pass the testing check. The changed language and worker paths retain boundary coverage: Full details: Testing (Property / Proof)Explanation Pass the Testing (Property / Proof) check. The pull request introduces property-based coverage for the new input and command-boundary invariants. Hypothesis tests exercise arbitrary whitespace-only Full details: Testing (Compile-Time / Ui)Explanation Treat this check as passed. The diff contains no Rust or TypeScript source changes, so no trybuild or equivalent compile-time test is required. The changed implementation is Python, Makefile, workflow YAML, configuration, and documentation. The new CLI and structured checks use focused assertions for error text, parsed Makeutil data, workflow fields, and exact argument forwarding. No new output surface requires a snapshot test; existing snapshot coverage remains unchanged. Full details: Unit ArchitectureExplanation Pass this check. The diff makes the main boundaries clearer. Full details: Domain ArchitectureExplanation Pass the Domain Architecture check. The PR changes GitHub Action adapters, workflow orchestration, build/lint configuration, documentation, and tests. The only non-test Python implementation change outside Full details: ObservabilityExplanation PASS: The pull request does not introduce a production service, storage, queue, network, or asynchronous operational path. The executable changes remove unused compatibility helpers or simplify signatures; Rust release execution still uses Full details: Security And PrivacyExplanation No explicit security or privacy failure is introduced. The PR adds no secret, credential, token, key, or personal data literal, and it does not change workflow permissions; affected jobs retain Full details: Performance And Resource UseExplanation Pass the Performance and Resource Use check. The production edits do not add a worse traversal or allocation pattern; the matrix and staging loops retain their existing bounded behaviour, and host-target detection removes a Rust probe. The new contract tests bound Hypothesis runs to 25 examples, cap generated strings at 40 characters, use temporary directories with cleanup, and apply 30-second subprocess timeouts. The Makefile parser handles a fixed 145-line Makefile. The additional CI toolchain and parser installations are intentional provisioning steps, not hot-path or unbounded work. Full details: Concurrency And StateExplanation No custom-check failure is introduced. The PR adds no async tasks, locks, shared registries, or new application-wide mutable state. Coverage execution remains explicitly single-threaded at the GitHub Actions step boundary, while pytest-xdist worker selection is pure and covered by parser, precedence, and CLI-boundary tests. CI matrix jobs install Makeutil independently on isolated runners, and the new recorder tests isolate temporary files. Existing workflow cancellation and concurrency controls remain in place. Full details: Architectural Complexity And MaintainabilityExplanation Pass the architectural complexity check. Keep the new Skylos layer: it addresses a real gap in production dead-code detection, uses the existing Full details: Rust Compiler Lint IntegrityExplanation PASS.

Reviewer's GuideAdopts Skylos dead-code detection as a strict lint gate for production Python code, wires it into local and CI workflows, documents the workflow for contributors, configures a precise allow list for known dynamic callsites, and removes or simplifies code that Skylos identified as unused or unnecessary while keeping behavior unchanged.

Run a pinned, blocking Skylos production scan from `make lint` and CI. Record verified static-analysis limits in the documented allow list, and remove confirmed unused helpers and stale test coverage. Document the new commit-gate behaviour and false-positive workflow for contributors and agents.
Pass the synchronized virtual environment to both Ty invocations so type checking resolves the project's declared third-party dependencies.
Use the project tool runner for both type-check passes so Ty resolves the synchronized project environment consistently.
Invoke Skylos's standalone whitelist subcommand without scan-only options, and cover the command shape with a focused Makefile contract test.
Run Skylos with its Python 3.14 AST runtime, validate its exception boundary through a Makeutil-parsed Makefile and recorder-backed property tests, and provision the pinned parser in full-suite CI jobs. Document the four-tier lint architecture and local parser bootstrap.
Exclude shell-subprocess examples from Hypothesis's per-example deadline so parallel host scheduling cannot fail the installer contract without a behavioural regression.

There was a problem hiding this comment.
The new helper unconditionally requires a make executable, but the inspected python-tests-windows job provisions only uv and Makeutil before running the entire pytest suite. The standard windows-latest environment does not provide GNU Make as a guaranteed tool, so this assertion fails before either skylos-allow property test can run; install Make in that job or skip these Makefile execution tests when it is unavailable.

Use structural match/case dispatch for LangMode.
get_lang handles three members explicitly, then routes every other value to _forced_mixed, which can hide future enum members. Replace the chain with one case for each current member, including LangMode.MIXED.

Extract the Makeutil installer into a composite action.
Move the repeated Rust toolchain and cargo install recipe into one local composite action. Replace each shell step with that action. Keep each caller responsible for its existing revision and toolchain inputs.

As per coding guidelines: Shared code must have a coherent home. Based on learnings: Use composite actions for simple orchestration or shell snippets.

Protect the documented-whitelist read-modify-write operation with an ignored repository-local `flock` lock, so concurrent contributors cannot discard verified exceptions. Pin the reviewed whitelist and entry-point sets in the Makeutil contract, and prove both isolated shell-safe forwarding and concurrent updates.
