Add RC-009 for the Project Plan against criteria taken from the Project Plan reference, since the framework has no QC checklist for it. Five defects found: wrong phase count, wrong delivery assumption, an overlapping MIL-003/MIL-004 schedule, and a stale risk and open issues. PP-001 v3 fixes them and is accepted; v2 is deprecated. The traceability matrix now points to RC-009. No issue closed: review and documentation only, no code changed.
