# Task Brief: criteria-runner fixture

Fixture only. Consumed by `tests/lib/criteria-runner.test.mjs`. It is the
falsifying case for D-04: a read-only reviewer cannot run these commands, so
/trekreview runs them and hands over the result.

## TL;DR

Three success criteria: one passes, one fails on purpose, one is prose only.

## Goal

Exercise the brief side of the criteria runner.

## Success Criteria

- The runner reaches the shell: `bash tests/fixtures/criteria-exit-0.sh` exits 0
- The failing case is visible: `bash tests/fixtures/criteria-exit-1.sh` exits 0 (FAILS on purpose — exit 1)
- No new runtime dependencies are introduced

## Non-Goals

- Being executed by the pipeline. This file is a test fixture.
