# Test plan — profile drift fixture

Frontmatter declares `profile: economy`. Step 1 manifest has matching
profile_used. Step 2 manifest declares `profile_used: premium` — the
drift case Step 20 of v4.1 plan-validator must catch in --strict mode.

## Implementation Plan

### Step 1: matching profile

- Files: a.ts
- Manifest:
  ```yaml
  manifest:
    expected_paths:
      - a.ts
    min_file_count: 1
    commit_message_pattern: "^feat:"
    bash_syntax_check: []
    forbidden_paths: []
    must_contain: []
    profile_used: economy
  ```

### Step 2: drift to premium

- Files: b.ts
- Manifest:
  ```yaml
  manifest:
    expected_paths:
      - b.ts
    min_file_count: 1
    commit_message_pattern: "^feat:"
    bash_syntax_check: []
    forbidden_paths: []
    must_contain: []
    profile_used: premium
  ```
