The added tests are substantial and exercise the main happy paths, workflow ordering, hostile LCOV inputs, fork handling, telemetry, and Check Run creation/update. They do not guard several new behaviours. The new Resolution Add substantive regression tests before merge. Assert Full details: Developer DocumentationExplanation The developer guide and ADR-021 document the new trust boundary, validator commands, Python tooling scope, and build configuration. However, the accepted ADR was changed retroactively without a logged addendum. Commit Resolution Keep ADR-021's accepted decision record immutable, or append dated Full details: Unit ArchitectureExplanation The PR introduces a query path that performs a network call. Resolution Refactor Check Run publication so the public command owns an explicit, fallible publication operation. Do not expose a query-shaped method that performs the GitHub GET. Inject a narrow transport dependency at the publication boundary, define explicit result and error handling for GET, POST, and PATCH, and keep payload construction in the pure reporting module. Test the command through the injected transport, including lookup failure, create, and update outcomes. LCOV crosses a guarded gate Comment |
Reviewer's GuidePR CodeScene coverage gating is isolated from untrusted pull-request execution by uploading only a short-lived LCOV artifact and validating it in a default-branch workflow_run on a fresh runner before step-scoped secret use, with extensive workflow contracts, poisoning regressions, validator tests, and developer documentation.

Inline comments:
In @.github/workflows/coverage-pr-submit.yml:
- Around line 71-72: Update the coverage check conclusion logic around the
submit_coverage outcome so skipped submission is reported as failure when
artifact download or validation did not succeed. Track those prerequisite step
outcomes explicitly, preserving neutral only when both prerequisites succeeded
and submission was skipped solely because the token was absent.
- Around line 38-44: Harden coverage artifact handling: in
.github/workflows/coverage-pr-submit.yml lines 38-44, enable skip-decompress on
actions/download-artifact; in .github/workflows/ci.yml lines 175-181, set
if-no-files-found to error on the coverage upload; and in
scripts/validate-coverage-artifact.py lines 132-135, replace unbounded
list(directory.iterdir()) with bounded enumeration that validates member count,
paths, types, and cumulative uncompressed size before extraction.
In `@docs/developers-guide.md`:
- Around line 812-814: Update the quality-gate guidance in developers-guide.md
to include the make test-coverage-artifact command, and state that changes to
the coverage artefact validator or trusted coverage workflow must run it;
clarify that make test does not execute this Python test suite.
In `@scripts/tests/test_validate_coverage_artifact.py`:
- Line 12: Replace the broad ruff suppression comments on the imports at
scripts/tests/test_validate_coverage_artifact.py lines 12-12 and 164-164 with
justified, rule-specific noqa comments using the appropriate rule code, or
remove the suppressions if unnecessary.
In `@scripts/validate-coverage-artifact.py`:
- Line 184: Update the required-record validation in the coverage artifact
validator to compare against individual LCOV lines rather than substring
matches, so each required record type such as SF: and DA: must be present as its
own line. Add a regression case covering fake embedded text like TN:SF:fake and
TN:DA:1,1.
- Around line 90-100: Replace the multi-branch conditional dispatch in
_format_validation_error with a structural match statement covering each
ValidationIssue case and its existing message behavior, and make the
corresponding dispatch change in _write_case. In
scripts/validate-coverage-artifact.py:90-100 update the formatter; in
scripts/tests/test_validate_coverage_artifact.py:50-71 refactor the fixture
setup to use focused helpers as requested, preserving all existing test coverage
and outcomes.
- Around line 41-42: Document the public interfaces ValidationIssue,
ValidationError, validate, and main with complete NumPy-style docstrings, adding
Parameters, Returns, and Raises sections wherever applicable. Describe each
parameter, return value, and raised exception accurately while preserving the
existing behavior.
Apply the same fix in `@tests/workflow_contracts/trust_boundary_invariants.py`
around lines 21 - 22: The same structured-docstring requirement applies to the
exported trust-boundary validators.
In `@tests/workflow_contracts/trust_boundary_invariants.py`:
- Line 50: Update the secret-step detection around is_isolated_secret_job to
scan each complete step rather than only step.get("env", {}), so secret
references in run or with are detected. Add regression mutations covering each
non-env secret-reference location and preserve the existing submission-step
isolation behavior.

Generate LCOV in untrusted PR CI and transfer only a bounded artefact to the default-branch workflow_run. Validate hostile data before the step-scoped CodeScene credential becomes available, then report the result as a Check Run for the originating SHA. Add contract and property regression coverage for PR secrets and runner environment poisoning.
Split the LCOV and artefact member checks into small validation helpers so the hostile-data gate remains clear and meets the CodeScene health threshold without changing its boundary or error contract.
Preserve the ordered validation errors while isolating the first invalid line and missing-record lookups. Add direct assertions for each issue and detail value so the security boundary remains stable.
Materialize the CRLF comparison candidate before invoking `cmp` so a non-canonical document cannot terminate `sed` through a closed pipeline. Cover the diagnostic contract with a large-document regression test.
Treat a skipped coverage submission as neutral only when artefact download and hostile-data validation both succeeded; any failed or skipped prerequisite now publishes a failing CodeScene check so a malformed artefact can no longer produce a non-failing gate. Harden artefact transfer on both sides of the trust boundary: the trusted workflow downloads the artefact without automatic extraction, and untrusted CI fails when the bounded LCOV upload finds no files. The validator now enumerates directory members under an explicit count bound instead of materialising an unbounded listing, and required-record checks compare individual LCOV lines so embedded fakes such as `TN:SF:` can no longer satisfy `SF:` or `DA:`. Document the validator and trust-boundary validator interfaces with NumPy-style docstrings, detect raw `secrets.CS_ACCESS_TOKEN` expressions in `run` or `with` surfaces as boundary violations, and regression-test symlinked directories, non-directories, directory members, external symlinks, and fake embedded records. Update the developers' guide so validator changes require `make test-coverage-artifact`, which `make test` does not run.
Meet the repository's YAML linting contract for the trusted coverage submission workflow.
Document the accepted workflow-run architecture for separating pull-request-controlled execution from CodeScene secret submission. Index the ADR and link it from the developer guide so the hostile artefact, eligibility, observability, and administrator controls remain discoverable.
Model Check Run outcomes in a checked-in pure seam and publish bounded source-run correlation without exposing secret or pull-request content. Exercise every hostile artefact filesystem boundary through both validator interfaces, and simplify the secret-job invariant without weakening its single-carrier rule.
Preserve every hostile-artefact diagnostic while expressing issue dispatch structurally. Keep CLI subprocess exceptions narrow and justified under the repository's Ruff policy.
Point the developer guide and ADR implementation reference at the underscore-named validator while preserving the existing Make target.
Keep checkout credentials out of untrusted CI and reject indexed secret expressions in executable workflow surfaces. Publish a neutral trusted Check Run for excluded forks without downloading their artefact or exposing the CodeScene token. Pin the workflow's validation and submission contract in behavioural tests, record bounded stage timing, and rename the validator to the repository's Python filename convention.
Measure the trusted coverage Check Run publication boundary with bounded source-run correlation fields. Keep workflow contracts strict for the fixed operation, ordering, and safe telemetry surface.
Separate Check Run and workflow-summary assertions so each bounded correlation contract remains directly reviewable without changing the trusted workflow.

Correct the checkout description in both trust-boundary documents.
actions/checkout uses the trusted default branch without sparse-checkout, so the workflow checks out the full default-branch tree and executes only the validation commands. Replace “checks out only ... validation tooling” in both documents with this accurate description, or add sparse checkout with a contract test.

Expand the five reporting helper docstrings.
make lint runs Ruff on .github/scripts with the NumPy D and DOC rules enabled. These parameterised helpers fail D417 because their docstrings contain no parameter descriptions. Add Parameters and Returns sections to report_values, summary, fork_summary, check_run_payload, and workflow_summary. The one-line exemption applies only to pydoclint rules.

Split _validated_member to clear the complexity gate.
CodeScene fails the build: _validated_member has a cyclomatic complexity of 12 against a threshold of 9. The path instructions set the same bound. The function performs four independent checks, and the boolean expression at Line 117 plus the generator at Line 122 add branches.
Extract each check into a named predicate. The validation order, the error classification, and the returned member stay identical.

Add direct archive-boundary regression cases.
coverage_artifact_archive.validate_and_materialize already rejects NOT_ZIP, ENCODING, and OUTPUT, and invokes ArchiveContract.validate_text. The archive test target has no coverage or mutation threshold, so this gap does not currently fail a repository check. Add archive-level cases for a non-ZIP file, non-UTF-8 content, malformed LCOV, and populated or symbolic-link output directories. Assert the diagnostic and that no output is materialised. Do not add a public-contract PATH case: _validated_member raises MEMBERS first for any name other than lcov.info.
