Summary

Scriptorium previously ran only repository tooling in GitHub Actions. This adds application tests on Blacksmith using the latest bsbyrdwfl/wfl:nightly image on main pushes, pull requests, and manual dispatch. Closes #13.

All five CMS suites and the pinned Scribe suite run through the existing test runner. Failed assertions and timeouts fail the job, and each run records the exact image and source revisions.

Changes

  • Pull nightly on every run, resolve its digest, and execute that immutable image.
  • Install Python inside a disposable container, mount the checkout read-only, and clean up the container even after cancellation.
  • Move Linux tooling checks to Blacksmith while preserving existing check names and Windows coverage.
  • Update testing and contributor documentation and the Scribe updater's validation guidance.

Compatibility and risk

  • Risk class and reason: R1, test infrastructure and documentation.
  • Affected contracts: CI execution only; application behavior, site data, configuration, and the Scribe pin are unchanged.
  • Upgrade and recovery: No migration. Revert these workflow changes to restore prior CI.
  • Remaining risks or gaps: Nightly intentionally moves between runs; digest and version are retained. HTTP/browser journeys, production compatibility, and host protection settings remain separate documented gaps.

Validation

  • Tested revision and environment: Final head 9de1ff334be1a58512489a82735112b0486ed251; Actions tests the PR merge revision recorded in the job summary. Blacksmith Ubuntu 24.04 x64, container Python 3.11.2, WFL 26.9.12, pinned Scribe 93d62af5a6ed6c3ce257ef888107fc3ca1e2dc1d.
  • Runtime image: bsbyrdwfl/wfl@sha256:7ddc51e6320affa7cfe26263fece590ddbdebe5582659b7e660ca823ed3ddbf1, resolved from nightly.
  • Regression evidence: Negative run at 658ee7d: a temporary expect 1 to equal 2 fixture produced exit 1 and a failed Actions job; all six real suites still ran and passed. The probe is removed from the final diff. Final positive run passes all six suites.
Check or exact command Result and evidence
python3 scripts/run_tests.py --include-scribe in nightly Docker Passed: 138 tests across 6 suites (55 CMS, 83 upstream Scribe).
python -m unittest discover -s tests/tooling -v 36 tests passed locally and in Governance on Blacksmith Linux and GitHub-hosted Windows, including runner timeout/failure paths.
python scripts/check_repo_hygiene.py Passed locally and in Governance on Linux and Windows.
actionlint 1.7.12 and git diff --check Passed; only actionlint's unknown-label diagnostic for the official Blacksmith runner was excluded.
Independent review No actionable findings in final diff; existing Governance check names preserved.
HTTP/UI, security, data migration N/A — application behavior and data contracts are unchanged.

Checklist

  • The title, summary, and risk assessment match the final diff.
  • Required validation is recorded above; failures and missing checks are explicit.
  • Documentation, examples, and upgrade/recovery guidance are updated where applicable.
  • I reviewed the diff for repository hygiene, secrets, and private site data.

The pull request adds WFL nightly testing on Blacksmith, records runtime evidence, maps Governance jobs to explicit runners, updates Scribe workflow verification, and revises CI documentation and adoption records.

Changes

WFL CI and verification

Layer / File(s) Summary
WFL nightly test workflow
.github/workflows/wfl-tests.yml
Adds pull request, push, and manual triggers. The workflow pulls bsbyrdwfl/wfl:nightly, records image and runtime metadata, runs application and pinned Scribe tests, and removes the test container.
Workflow gating and runner integration
.github/workflows/governance.yml, .github/workflows/update-scribe.yml
Maps Ubuntu Governance jobs to blacksmith-2vcpu-ubuntu-2404. Scribe update instructions now require Governance and WFL results for the current revision.
CI policy and repository guidance
CLAUDE.md, CONTRIBUTING.md, README.md, testing.md
Documents the new workflows, runtime evidence, manual dispatch, verification requirements, and WFL application-test adoption status.

Consider pinning actions/checkout to an immutable commit SHA.

@v4 is mutable, so a tag change could alter the workspace before tests run. The read-only container mount does not protect the checkout step. This is supply-chain hardening, not a current major CI defect. No applicable repository requirement for immutable action references is documented.
