# Plan: criteria-runner fixture (one criterion FAILS on purpose)

Fixture only. Consumed by `tests/lib/criteria-runner.test.mjs`. It is the
falsifying case for D-03: a plan whose declared success criterion does not
hold must fell the single-session run instead of being noted and passed over.

## Steps

### Step 1 — nothing

Fixtures have no steps worth running.

## Verification

- [ ] `bash tests/fixtures/criteria-exit-0.sh` -> expected: exit 0
- [ ] `bash tests/fixtures/criteria-exit-1.sh` -> expected: exit 0 (FAILS on purpose — exit 1)

## Estimated Scope

- **Files to modify:** 0
