# Demo plan for annotation round-trip

This fixture is used by `tests/integration/annotation-roundtrip.test.mjs`
to verify SC2 (byte-identical empty-anchor round-trip) and SC7 (per-target
isolation against `validatePlan`).

## Context

A minimal plan with two steps. Each step has a Manifest block so
`plan-validator --strict` accepts the file.

## Implementation Plan

### Step 1: Touch a sentinel file

- **Files:** `tmp/sentinel-1.txt` (new)
- **Changes:** Create the sentinel file with the literal content "step-1".
- **Reuses:** none.
- **Test first:** none — sentinel-only step.
- **Verify:** `test -f tmp/sentinel-1.txt`
- **On failure:** revert.
- **Checkpoint:** `git commit -m "chore: sentinel step 1"`
- **Manifest:**
  ```yaml
  manifest:
    expected_paths:
      - tmp/sentinel-1.txt
    min_file_count: 1
    commit_message_pattern: "^chore: sentinel step 1"
    bash_syntax_check: []
    forbidden_paths: []
    must_contain: []
  ```

### Step 2: Touch a second sentinel file

- **Files:** `tmp/sentinel-2.txt` (new)
- **Changes:** Create the sentinel file with the literal content "step-2".
- **Reuses:** none.
- **Test first:** none.
- **Verify:** `test -f tmp/sentinel-2.txt`
- **On failure:** revert.
- **Checkpoint:** `git commit -m "chore: sentinel step 2"`
- **Manifest:**
  ```yaml
  manifest:
    expected_paths:
      - tmp/sentinel-2.txt
    min_file_count: 1
    commit_message_pattern: "^chore: sentinel step 2"
    bash_syntax_check: []
    forbidden_paths: []
    must_contain: []
  ```

## Verification

- `npm test` passes.
- Both sentinel files exist.
