ci: execute validator unit test suites in CI workflow

[mjmirza]

Problem Reproduction

In .github/workflows/ci.yml, several validator unit test suites (tools/check-prose-test.py, tools/gen-indexes-test.py, tools/check-code-test.py, and tools/check-claims-test.py) were absent from their respective workflow jobs. While Makefile targets executed them locally, GitHub Actions CI executed the primary validator scripts (check-prose.py, gen-indexes.py, check-code.py, check-claims.py) without running their unit tests first.

Root Cause

When unit test suites for check-prose, gen-indexes, check-code, and check-claims were authored in PRs (#449, #266), they were registered in the Makefile test target but omitted from .github/workflows/ci.yml.

Evidence

Running a custom workflow auditor (ci_checker.py) showed that out of 10 test scripts in tools/, only check-structure-test.py, check-family-names-test.py, gen-by-problem-by-language-test.py, and gen-catalogue-status-test.py were invoked in CI.

Historical Duplicate Audit

Audited all branches, git history, and merged/closed PRs. No previous PR or branch attempted to add check-prose-test.py, gen-indexes-test.py, check-code-test.py, or check-claims-test.py steps into .github/workflows/ci.yml.

Why Now

Ensuring that CI tests the validators before executing them prevents silent validator regressions or broken assertion logic from reaching main.

Solution

Added workflow steps in .github/workflows/ci.yml:

1. Prose validator tests (tools/check-prose-test.py) before Prose gate in the structure job.
2. Family index generator tests (tools/gen-indexes-test.py) before Indexes are current in the structure job.
3. Code validator tests (tools/check-code-test.py) before Compile every sample in the code job.
4. Claim check validator tests (tools/check-claims-test.py) before No two contributors on the same entry in the claims job.

Alternatives

• Rely solely on Makefile locally: Risk of contributor running validators directly without running tests locally.
• Combine test scripts into a single script: Worse granularity and log output in GitHub Actions job summaries.

Before/After Measurement

• Before: CI executed 4 out of 8 validator test scripts.
• After: CI executes 8 out of 8 validator test scripts. Added runtime is under 7 seconds total.

Security Analysis

Only .github/workflows/ci.yml is modified. No content changes are included in the same PR. Security gate in check-pr-security.py functions as designed requiring maintainer security-reviewed label for workflow changes.

Performance Analysis

Total additional CI runtime across structure, code, and claims jobs is < 7s.

Compatibility

Fully compatible with existing GitHub Actions workflow triggers, permissions, and environments.

Maintenance Cost

Zero added maintenance cost; reuses existing stdlib unittest suites.

Rollback

Revert the commit in .github/workflows/ci.yml.
