+## Notes
+
+- Time estimates assume ~6–8 productive hours per day.
+- Add **20–30% buffer** for unexpected issues.
+- Testing time is included in each estimate.
+- Documentation is distributed throughout rather than batched at the end.
+- Package management (3.2) can be deferred if time-constrained.

+- CLI emulator (Phase 6) is explicitly a "nice to have" and should not block other work.
