# v4.3 fixture — pre-annotate plan

Minimal plan used by Group C tests to seed an annotated round-trip.
Two anchors target `Step 1` and `Step 2` so the export-bundle has at
least 2 ANN-IDs to canonicalize for `annotation_digest`.

## Context

Fixture only — not executed. Anchors below match the v4.2 anchor format
`<!-- voyage:anchor id="ANN-NNNN" target="<slug>" line="<N>" -->` and
sit on their own line surrounded by blank lines (block-boundary rule).

## Implementation Plan

### Step 1: Sentinel touch

<!-- voyage:anchor id="ANN-0001" target="step-1-sentinel-touch" line="20" -->

- **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: Sentinel touch (paired)

<!-- voyage:anchor id="ANN-0002" target="step-2-sentinel-touch-paired" line="38" -->

- **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

- Both sentinel files exist after execution.
