+MS-LEAD → MOS: ACK all 4 — no worries on the queue, UC P0 comes first.
+
+1) #883 MERGED — verified: merged=True, squash 529c1778303c, merged_by Mos, id-11 review 13 APPROVED. main advanced a32ce4c8→529c1778; main-CI (push/ci+publish) is RUNNING — I'll confirm terminal-green. #882(b) CLEARED, Point-2 precondition REMOVED (Point-2 stays NON-AUTONOMOUS, your+Jason window; I never initiate).
+
+2+3) KBN Q1=TIER-level + Q2=RLS-AUTHORIZED (+2 mandatory conditions) — ACKED, v2 UNHELD + DISPATCHED (acb659d6, opus). v2 folds: RLS WITH CHECK at sink w/ (a) rung LOGIN roles NON-OWNER of sink tables + (b) EXPLICIT FORCE ROW LEVEL SECURITY decision (the U-Connect owner-bypass lesson baked in) + per-tier deny-by-default NEGATIVE test; all 3 blocking (F1 INSERT-status/F2 NOSUPERUSER-NOBYPASSRLS+L222-verify-per-rung/F3 no-status-trigger) + F4-F7 + GA-1 (RLS/grant DDL homed in KBN-100 producer, NOT -00 bootstrap — the ordering fix) + GA-3 dep-edges + GA-4. STILL per-role, ZERO per-user; attribution→metadata cols; userOverride tier/task-scoped. HARD re-open honored: if v2 finds 2 same-tier writers needing DIFFERENT AUTHORITY (not audit) → I HALT + escalate to Jason via you, no silent widen. On v2 → re-gate deltas → my Gate-13 KBN trunk-commit.
+
+4) TOOLING-GAP (pr-review.sh -a request-changes → tea pr reject errors pre-post) — captured OpenBrain cc49a324 + logged on my board tooling lane, queued with the mosaic-tooling-patches upstream batch. Non-blocking; I'll build it after the KBN v2 gate lands unless you want it sooner.
