Why: Dev has to follow the commits that landed on Backend and Documents main, which share trees with the drilled objects.
Evidence: Backend dc736e339d01 tree 498f61947564 equals 46073d30. Documents 05c13a42b14d tree equals 5335499. GATE run 2794 on 6d8b746 succeeded before this pin.
Impact: gitlinks move to the merge commits. Second-instance writes stay closed.
Refs: #186#92#497

Why: the restored drill passed artifact recovery, and the handbook, checklist, and collaboration plan have to say so without opening write traffic.
Evidence: backup-20261013-013354 on Dev a83588dd and backend 46073d30; K1-K7 true, RPO 65s, RTO 3s, five artifacts matched, cross-user access 404. SELF. Documents 5335499 is PR #92.
Impact: C5 is marked SELF-pass. Second-instance writes stay closed until REPLAY or CI and a second host exist.

Why: The measured backup, PITR, and disconnect steps were only in the drill scripts, and the checklist still said those rows were not run.
Evidence: Results pgbench-20261012-131948, fault-20261012-142734, and backup-20261012-153441 (SELF). K4 stays failed.
Impact: Second-instance write traffic stays closed. The handbook records the upload panic and the short socket path.

Why: collaboration storage U7 (proposal sections 3/5/7) requires two-process
HTTP-level acceptance over shared PG, a reproducible load-test entry honoring
the load contract, and an auditable pre-release checklist; capacity windows and
dual-host runs need user-scheduled resources, so the deliverable here is the
verifiable entry, not capacity claims.
Evidence: make test green (composite); make test-multi-instance green locally
against an isolated PG (five scenarios incl. crash-takeover and restart
invariants); run_load.sh --profile smoke end-to-end green (SSE probe p95~18ms,
zero seq duplicates, stack auto-recycled); backend pinned to feature branch
with the three cross-instance fixes.
Impact: new tests/integration/multi-instance (CI test-pg job step), new
tests/load/collaboration (k6 + SSE probe + run_load.sh), release checklist at
docs/release-multi-instance.md; no runtime behavior change in Dev repo itself.
