Implement With Senior Dev

Implement the approved plan as the smallest complete patch. Repository evidence decides how code is written; the plan decides what behavior may change; the implementation contract proves what actually happened.

Read Before Acting

Read these files completely before editing:

1. references/implementation-contract.json — authoritative run-bundle fields, statuses, and safety policy.
2. references/implementation-protocols.md — canonical intake, editing, propagation, verification, and recovery procedure.
3. references/code-quality-checklist.md — per-file and final quality gates.
4. references/implementation-hazards.md — exact stop/recovery decisions.
