A bug fix is not done until the evidence exists

The five checkpoints

1. Reproduce — write the smallest reliable repro before touching code
2. Explain — state the likely cause in one sentence and link the evidence
3. Patch — make the smallest change that addresses the cause
4. Verify — run the regression test plus the nearest adjacent flow
5. Show — attach a screenshot or short recording to the ticket

Agent boundaries

• No auto-merge
• No closing a ticket on a green unit test alone
• Auth, billing, and destructive actions require human review

Done means

The next engineer can understand what broke, why the patch is safe, and what proof was collected.
