Record the 2026-10-13 C5 K4 retest: five artifacts matched and cross-user access was denied.
Move the collaboration plan to r2.3. Second-instance write traffic stays closed.
Test plan
Drill backup-20261013-013354 on Dev a83588dd / backend 46073d30 (SELF): K1–K7 true, RPO 65s, RTO 3s
Documents has no CI workflow; this PR has no GATE job
Why: the 2026-10-12 report left K4 failed, and the retest is now the plan's current SELF result.
Evidence: preserved at /home/weichen/projects/u7-k4-retest-preserved-20261013 and on the Dev task card.
Impact: documentation only. Write traffic is still not released.

## Summary
- Record the 2026-10-13 C5 K4 retest: five artifacts matched and cross-user access was denied.
- Move the collaboration plan to r2.3. Second-instance write traffic stays closed.
## Test plan
- [x] Drill `backup-20261013-013354` on Dev `a83588dd` / backend `46073d30` (SELF): K1–K7 true, RPO 65s, RTO 3s

Why: the 2026-10-12 report left K4 failed, and the retest is now the plan's current SELF result.
Evidence: preserved at `/home/weichen/projects/u7-k4-retest-preserved-20261013` and on the Dev task card.
Impact: documentation only. Write traffic is still not released.
Refs: Dev branch `fix/u7-k4-artifact-upload`.
Why: the 2026-10-12 drill left artifact recovery failed, and the retest changed that SELF result without changing the write-traffic gate.
Evidence: backup-20261013-013354 on Dev a83588dd and backend 46073d30; K1-K7 true, RPO 65s, RTO 3s, five artifacts matched and cross-user access returned 404. SELF.
Impact: proposal moves to r2.3. Second-instance writes stay closed until REPLAY or CI and the second host exist.
