Implement a story with your agent, end to end

What the agent does

1. Reads the story's work context: why-chain, criteria, constraints, decisions, any handover note.
2. Moves it to In progress.
3. Checks the code area before editing, then implements with tests.
4. Registers the tests against the criteria and reports results.
5. Proposes the design changes the story makes, if it has none yet.
6. Opens a pull or merge request citing the record codes and the story code, and moves the story to Code review.

What you do

• Review the pull or merge request.
• Verify criteria or let CI do it.
• Move the story to Done. Its design changes then update the solution's design.
