scripts/ci-guards/ — Regression-guard scripts

Each <id>.sh script in this directory pins one closed audit finding from regressing. CI runs the full set on every push via the Regression guards step in .github/workflows/ci.yml. Operators can run any script locally:

bash scripts/ci-guards/G-3-env-docs-drift.sh

Contract

Every script in this directory MUST:

1. Be exit-code 0 on a clean repo (no regression present).
2. Be exit-code non-zero on regression, with a ::error:: annotation prefix so PR reviewers see the failing line in the GitHub Actions UI.
3. Be runnable from repo root via bash scripts/ci-guards/<id>.sh with NO arguments and NO env-var requirements. The CI loop step (for g in scripts/ci-guards/*.sh; do bash "$g"; done) iterates every .sh here without args; any script that requires an arg or env var WILL fail in that loop.
4. Carry a head-comment block matching the in-source justification from the original ci.yml entry: the audit-finding reference, the closure rationale, the exempt-surface list (if any).
5. Use set -e early to fail-fast on internal command errors.
6. Produce no output on the happy path beyond a final echo "<id>: clean." confirmation line.

Helpers vs guards

Scripts that consume input artifacts (a test-output log, a coverage.out file) or env vars (PR_NUMBER, GH_TOKEN) are HELPERS, not guards. They live in scripts/, NOT scripts/ci-guards/.

Current helpers:

• scripts/vendor-e2e-skip-check.sh — consumes test-output.log arg from the deploy-vendor-e2e job
• scripts/coverage-pr-comment.sh — consumes coverage.out + PR_NUMBER + GH_TOKEN env from the go-build-and-test job
• scripts/check-coverage-thresholds.sh — consumes coverage.out
  • .github/coverage-thresholds.yml
• scripts/qa-doc-part-count.sh + scripts/qa-doc-seed-count.sh — invoked via make verify-docs pre-tag, not in CI

Adding a new guard

1. Drop a new <id>.sh in this directory with the head-comment block describing the audit finding it closes.
2. Make it executable: chmod +x scripts/ci-guards/<id>.sh.
3. Verify it fails on a deliberate regression and passes on clean repo.
4. CI auto-picks up new scripts via the for g in scripts/ci-guards/*.sh loop in the Regression guards step — no ci.yml change required.

Guards explicitly NOT here

• QA-doc Part-count drift + QA-doc seed-count drift — these protect docs-the-operator-reads, not anything the product depends on. Moved to make verify-docs (operator runs pre-tag, not on every push). See the ci-pipeline-cleanup spec, Phase 11.
