fix(streaming): stop replaying committed recenter retirements

Browse source 
Root cause: pending-only live projection buckets were misclassified as landblock presentation owners during origin recentering. That manufactured a second full cleanup receipt for a generation whose first receipt was still advancing; the duplicate guard threw and the broad retry path replayed the already-committed detach 243 times.

Keep pending live projections through the spatial identity map without issuing another receipt, and fail fast when a receipt-ledger invariant occurs after detachment. Evidence: docs/research/2026-08-02-collision-throughput-handoff/p1-retirement-receipt-loop.md. Release suite, lifecycle gate, and nine-stop soak pass.

@ -80,6 +80,14 @@ loader branch there. Slice 4B must preserve the flag while mapping successful

the presence of the flag in the immutable request is not claimed as exactness.
AD-2 retirement-receipt refinement (2026-08-02): a pending-only live
projection bucket survives the atomic origin swap but is not a landblock
presentation generation and emits no second full cleanup receipt. A genuine
receipt-ledger invariant after spatial detachment is a committed terminal
failure, never resumable detach work. This preserves the existing adaptation:
one exact asynchronous cleanup owner for each synchronously destroyed retail
landblock, while logical live objects survive streaming residence changes.
