HIGH: Changed-address now requires OutcomeCatchUp and fails if not.
No more conditional execution — must go through full catch-up chain.
MED: Overlapping retention is now true simultaneous overlap:
- Hold 1 at LSN T+1, Hold 2 at LSN T+2 — both coexist
- MinWALRetentionFloor = T+1 (minimum of two)
- Release hold 1 → floor moves to T+2
- Release hold 2 → ActiveHoldCount=0, no floor
MED: NeedsRebuild now asserts escalated event in logs.
PostCheckpoint now asserts handshake + catch-up execution events.
