  Auto-trigger when claiming a feature, worker, or integration is done, shipped,

# prove-it-ship-gate

Thin routing skill for ship/done claims with live side effects.

Follow Invoker or a locally installed `prove-it` for the shared evidence rule.
This file only adds the ship/done auto-route; it does not replace `prove-it`.

## Rule

When the work under claim has live side effects:

- **Fixture ≠ live.** Unit tests, mocked fixtures, and UI registration Visual
  Proof do not prove the live path ran.
- Before stating done / shipped / working: show **live evidence in the same
  turn**, or prefix the claim with `UNVERIFIED: live path`.
- Do not frame UI Visual Proof (for example worker registration in a settings
  panel) as product e2e of the live side effect.

## Mechanical enforcement

The same-turn check is a Stop hook, `engine/hooks/prove-it-ship-gate/`
(installed by `install.sh`). It blocks the turn when a done/shipped/live claim sits
near a live-side-effect noun with no chaseable evidence, no live command this turn,
and no `UNVERIFIED: live path` prefix. This file keeps the judgment half: deciding
whether the work really has live side effects.

## Incident

Invoker PRs published cross-repo-research after unit + fixture +
UI only; the user forced a live Linear e2e and a reflect afterward.

## Related

If the claim isn't done/shipped but repeated failed attempts on one problem within a live session, that's `narrow-the-scope`, not this skill.

If a grading/validation board came back FAIL or NEEDS_WORK, or the user says "/thrash", that's `thrash-reflect-automate`.
