# `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
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 `cowork/ci-pipeline-cleanup-prompt.md` Phase 11.

## Running the full set locally

```bash
for g in scripts/ci-guards/*.sh; do
