planck flagged via mai report feedback (id 12301) after the B5+B6
verification round caught them:
- §5.4 'INSERT into paliad.project_parties' → real table is paliad.parties
- §5.4 'status=open' → real CHECK constraint allows pending/completed/cancelled/waived
- §7.4 listed verfahrensablauf-detail-mode.ts as dead code, but builder
imports filterByDetailMode from it; struck through with KEEP note.
Code shipped (B5+B6) used the correct values throughout; this aligns
the historical PRD with reality so a future reader doesn't repeat the
verification time planck spent.
