## Minimum Ready-for-Execution Checklist
Mark all as true before queueing this project for build:
- [ ] Personal significance and must-not-fail outcomes are explicit.
- [ ] Constraints are quantified (latency, throughput, hardware, budget).
- [ ] Acceptance criteria are executable pass/fail checks.
- [ ] Rollback and migration strategy are concrete.
- [ ] API/data contracts are versioned and compatibility expectations are clear.
- [ ] Risk register includes mitigations and contingency plans.
