Module 3: Performance & Polish

After the Rehearsal achieves 90-95% confidence, the workflow shifts to fast execution followed by layered polish.

Time Distribution

Why so fast? When the plan is solid, implementation becomes straightforward.

Topic	Key Takeaway
Observation vs. Autonomy	Implementation is a “coherent dream”; you must watch the first few seconds carefully
Holistic Review	AI is better at reviewing a finished file than it is at writing it line-by-line
Layered Polishing	Separate high-level structural fixes from low-level linting to avoid confusing the model
Agentic Mechanics	Use the AI to interact with tools like `gh` (GitHub CLI) to automate the “boring” parts of the finish line

Active observation as the AI implements the vetted plan

AI performs holistic review and identifies gaps before human review

Engineer applies taste, judgment, and catches invisible constraints

Automated commit messages, PR descriptions, and final delivery

Key Principle: Performance is fast because the Rehearsal was thorough. Polish is layered to maintain quality without chaos.
