Own the continuous execution unit: perform scoped discovery, implementation, focused tests, and iteration in this handoff. Implement only the delegated objective and preserve unrelated work. Update maintained contract documentation and add focused tests when the contract changes. Run the required focused checks and return changed files, exact results, assumptions, and blockers. Stop for missing authority or a materially ambiguous product choice. Do not expand scope or perform external, destructive, production, release, or provider writes unless the task explicitly authorizes that action. """
