# Implementation Plan: MMA Verification Mock Track

## Phase 1: Delegation Flow
- [ ] Task: Tier 2 delegates creation of `hello_mma.py` to a Tier 3 Worker.
- [ ] Task: Tier 2 simulates a large stack trace from a failing test and delegates to Tier 4 QA for a 20-word fix.
- [ ] Task: Tier 2 applies the Tier 4 fix to `hello_mma.py` via a Tier 3 Worker.
- [ ] Task: Verify the final file contents.
