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.
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.
Keep the Python linting section compliant with the Markdown lint gate.
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.
Install GNU Make before the Windows full pytest suite so the Skylos Makefile execution contracts have the required executable. Assert the Chocolatey provisioner in the workflow contract to prevent a future CI change from removing that prerequisite.
Make language dispatch exhaustive, share the pinned Makeutil bootstrap, and reject wildcard symbols before they reach the documented Skylos whitelist. Group the related contract tests while preserving their generated coverage and assert the composite action contract in every full-suite workflow.
Remove the unused cargo-nextest lookup wrapper and its dedicated tests. Document the two watchdog helpers reached through the action-local module boundary so the strict Skylos gate retains their verified runtime use.
Remove the production-dead `audit_commits` wrapper and unused `SOURCES` marker. Record only verified analyzer false positives for conditional imports and urllib's handler-order protocol attribute. Keep commit-audit tests on the live parsing and rule functions, and correct the platform and documentation contracts exposed by the rebased main branch.
Regenerate the checked-in spelling configuration so it reflects the repository's current spelling policy and accepted terms.

🌐 Web query:
official GitHub Actions runner images macos-15 windows-latest flock command installed
💡 Result:
**Short answer:**
- **`macos-15`:** GitHub’s official image inventory doesn’t list `flock` among the installed software, so it isn’t confirmed as preinstalled. The inventory may not enumerate every OS-provided utility; check at runtime with `command -v flock`. ([github.com](https://github.com/actions/runner-images/blob/main/images/macos/macos-15-Readme.md?utm_source=openai))
- **`windows-latest`:** This currently maps to Windows Server 2025, whose installed-software list doesn’t include `flock`. It isn’t a standard native Windows command; the image does include Bash, but the inventory doesn’t establish whether `flock` is available in that environment. ([github.com](https://github.com/actions/runner-images?utm_source=openai))
For certainty in a workflow, test `flock` with `command -v flock` (macOS/Bash) or `where.exe flock` (Windows).

Declare and provision flock, or replace it with a portable lock.
skylos-allow invokes the bare flock command before Skylos updates the whitelist. The macOS and Windows jobs do not provision flock, and the runner inventories do not guarantee that it is available. If flock is missing from PATH, the recipe exits before the update runs. Provision flock on every supported host, or use a cross-platform lock that preserves serialization around the complete update.

Update the skylos-allow recipe to avoid relying on an unprovisioned flock
command: either ensure flock is installed on every supported host or use a
cross-platform lock, while preserving serialization around the complete
whitelist update.

🎯 Functional Correctness | 🟠 Major | ⚡ Quick win
Normalise CRLF line continuations before tokenising Makeutil values.
On Windows, the checkout converts the Makefile to CRLF. value.replace("\\\n", "") does not match a \ followed by \r\n. Because of this, SKYLOS_PRODUCTION_TARGETS keeps a carriage-return token, and the Windows CI job fails. _recipe_tokens and _assert_makeutil_installation have the same defect. Replace \r\n with \n first. Then remove the continuation. The assertion stays exact.

Normalize CRLF to LF before removing Makefile line continuations, and reuse that
normalization in _variable_tokens, _recipe_tokens, and
_assert_makeutil_installation so token assertions remain exact on Windows. Add
the requested Makefile LF rule to .gitattributes as a safeguard.

🩺 Stability & Availability | 🟠 Major | 🏗️ Heavy lift
Make the whitelist lock portable, or gate these tests on flock.
The skylos-allow recipe calls flock. flock is not available on macOS or Windows runners. Because of this, test_skylos_allow_forwards_generated_arguments_exactly and test_skylos_allow_lock_preserves_concurrent_documented_entries fail on those runners. The preferred fix is to replace flock in the Makefile with a small Python lock wrapper. For example, the wrapper can use fcntl.flock, and msvcrt.locking on Windows. This change keeps the concurrency guarantee on every platform. If the recipe stays POSIX/flock-only, mark both tests with pytest.mark.skipif(shutil.which("flock") is None, reason=...), and document the platform limit. Update _SKYLOS_WHITELIST_TOKENS so that it matches the chosen recipe.
Replace the `flock` call in the Makefile `skylos-allow` recipe with a cross-platform Python lock helper that holds an exclusive lock on $(SKYLOS_WHITELIST_LOCK) while it runs the Skylos whitelist command. Update `_SKYLOS_WHITELIST_TOKENS` in workflow_scripts/tests/test_skylos_lint_contract.py, and update AGENTS.md/docs/developers-guide.md, which currently mention `flock`.
