📝 WalkthroughWalkthroughAdded a change-detection job to conditionally run language-specific CI checks, rewrote coverage upload to use parallel Coveralls uploads and a parallel-finished finalizer, and added a verification job plus workflow permissions to fail the run when required checks neither succeeded nor were skipped.

Greptile SummaryThis PR refactors the Key changes:
Confidence Score: 5/5Safe to merge — logic is correct across all conditional execution paths, coverage finalization, and the verify gate. The workflow change is well-reasoned and internally consistent. The conditional || in finish_coverage_upload correctly handles the case where only one language job ran. The carryforward setting handles skipped jobs gracefully. The verify job correctly treats both success and skipped as acceptable states. No P0 or P1 issues were identified. No files require special attention.

job (and the dorny/paths-filter step) add a top-level permissions: entry
granting only pull-requests: read (required by dorny/paths-filter) plus any
other minimal permissions needed by downstream steps (e.g., statuses: write if
Coveralls needs it); ensure no broad permissions like write-all are used and
GITHUB_TOKEN is not implicitly allowed beyond these explicit permissions.

Pull request overview
Refactors the run_code_checks GitHub Actions workflow to reduce CI runtime by only running language-specific checks when relevant files change, and updates coverage reporting to Coveralls using parallel uploads.
Changes:
- Add a
detect_changesjob (viadorny/paths-filter) and gate Rust/Python/Markdown/YAML jobs based on detected file changes. - Switch Rust/Python coverage handling from artifact upload/download to per-job Coveralls uploads with a final “parallel-finished” step.
- Add a final
verify_all_checks_passedjob to fail the workflow if any required job fails/cancels (while allowing skipped jobs).

…kflow gaps - Add workflow-level permissions block (contents: read, pull-requests: read, statuses: write) to restrict GITHUB_TOKEN scope per GitHub Advanced Security and CodeRabbit recommendations - Add maskfile.md, .flox/**, devenv.* to rust and python paths-filter rules so shared CI entrypoint changes trigger the appropriate language checks - Add detect_changes to verify_all_checks_passed needs so a failure in detect_changes is caught rather than silently skipped Co-Authored-By: Claude <noreply@anthropic.com>

In @.github/workflows/run_code_checks.yaml:
- Around line 30-49: The workflow filters currently won't match the workflow
file itself or the shared CI inputs; update the filter sets so the
Rust/Python/Markdown/YAML groups include the workflow and shared inputs patterns
(e.g., add a pattern matching the workflows directory or this file such as
'.github/**' or specifically the workflow filename) and ensure '.flox/**' and
'devenv.*' are present in the Markdown and YAML filter blocks as well so the
refactored job paths and Flox/devenv inputs are exercised; adjust the keys shown
(rust, python, markdown, yaml) to include those additional patterns so
run_code_checks.yaml and shared CI files are detected.
- Around line 151-164: The Coveralls finalization step currently runs when
either language job succeeds (using OR) which allows publishing stale coverage
via the carryforward parameter even if the other job failed; update the workflow
`if` condition for the "Finalize coverage upload" step to require both
`needs.run_rust_code_checks.result == 'success'` AND
`needs.run_python_code_checks.result == 'success'` (so the step only runs when
both language checks succeeded) and keep `parallel-finished`/`carryforward`
as-is for true skipped jobs.
- Around line 90-96: Guard the Coveralls upload step by checking
.coverage_output/rust.xml exists before running it: add a preliminary step (id:
check-rust-coverage) that runs a shell test like [ -f .coverage_output/rust.xml
] and sets an output (rust_exists) to "true" or "false", and then add an if:
condition on the Coveralls step (the step using coverallsapp/github-action@v2)
such as if: steps.check-rust-coverage.outputs.rust_exists == 'true' so the
upload (file: .coverage_output/rust.xml, flag-name: rust) only runs when the
rust.xml file is present.

168-173:⚠️ Potential issue | 🟡 MinorCoveralls finalization may still mask failed jobs with stale coverage.
The current condition allows
parallel-finishedto run when one job succeeds and the other fails. Withcarryforward: rust,python, a failed Python job would still publish the last known Python coverage from a previous build, masking the failure in coverage metrics.Consider strengthening the condition to ensure neither job failed:
🧭 Suggested condition to prevent stale coverage on failure
if: | always() && + ( + needs.run_rust_code_checks.result == 'success' || + needs.run_rust_code_checks.result == 'skipped' + ) && + ( + needs.run_python_code_checks.result == 'success' || + needs.run_python_code_checks.result == 'skipped' + ) && ( needs.run_rust_code_checks.result == 'success' || needs.run_python_code_checks.result == 'success' )This ensures coverage is only finalized when all language jobs either passed or were intentionally skipped (no changes detected), preventing stale carryforward data from masking actual test failures.

- Around line 128-134: Add the same file-existence guard used for Rust: create a
prior step (e.g., "Check Python coverage file") that checks for
.coverage_output/python.xml and sets an output like coverage_exists, then add an
if condition to the "Upload coverage to Coveralls" step so it only runs when
that output is true; reference the step name "Upload coverage to Coveralls" and
the target file ".coverage_output/python.xml" when making the change.
