+# Tick 0131Z — PR #3081 reviewer findings absorbed; all 4 hazard PRs cleanly resolved
+
+## Refresh
+
+5 open PRs. byGate: {BLOCKED: 2, CLEAN: 2, DIRTY: 1}.
+
+| PR | State | Status |
+|---|---|---|
+| #3084 | BLOCKED, CI wait, auto-armed | this session's 0120Z shard |
+| #3083 | CLEAN, no threads, no auto-merge | NEW — stacked on #3079; legitimate EXPERT-REGISTRY xref fix (PM-1/Otto → Leilani) |
+| #3082 | **MERGED** (ba7a014) | ⚠️ → ✅ rebased before merge per hazard flag |
+| #3081 | BLOCKED, 2 unresolved threads → 0 (this tick), auto-armed | this session's 0109Z shard |
+| #3075 | DIRTY, 6 threads, auto-armed, needs rebase | still deferred from 0120Z tick |
+
+## Step 4a — PR #3081 reviewer findings absorbed
+
+Two findings on the 0109Z shard:
+
+- **P1 (MD032)**: same line-wrap-puts-`+`-at-line-start pattern as PR #3080's
+  self-violation. Rewrap so `+ refresh-before-decide` becomes
+  `and the refresh-before-decide`. Commit
+  [5a8c8ea](https://github.com/Lucent-Financial-Group/Zeta/commit/5a8c8ea).
+- **P2 (duplicated word)**: "failure-mode mode" → "failure mode".
+
+Both threads resolved via GraphQL mutation (`PRRT_kwDOSF9kNM6B7rxM`,
+`PRRT_kwDOSF9kNM6B7rxY`).
+
+## Step 4b — Hazard-flag system verification
+
+All four hazard PRs from prior ticks now resolved correctly:
+
+| PR | Pre-flag state | Post-flag outcome |
+|---|---|---|
+| #3077 | CLEAN gate, -379 lines if merged | rebased + MERGED (f4d7fca) — substrate intact |
+| #3078 | CLEAN gate, -379 lines if merged | rebased + MERGED (3f1d95b) — substrate intact |
+| #3079 | CLEAN gate, -285 lines if merged | **CLOSED** as obsolete per recommendation |
+| #3082 | CLEAN gate, **-180K lines** / 1462 files if merged | rebased + MERGED (ba7a014) — substrate intact, only 3 file adds remain in final merge |
+
+Hazard-flagging system works end-to-end: surface CLEAN signal → manual
+substrate-honest review → flag → author/maintainer rebase → safe merge.
+
+## Step 4c — PR #3083 noted (legitimate change, stacked on closed #3079)
+
+`fix(pm2): replace dangling PM-1/Otto xref with resolvable Leilani role-ref`
+fixes a real issue: `docs/EXPERT-REGISTRY.md`'s PM-2 row referenced
+`PM-1 (Otto)` but neither `pm1.md` nor `otto.md` agent file exists,
+making the xref unresolvable.
+
+The proposed fix replaces it with `Leilani` (the Product/Scrum Master
+persona that IS in the registry). This is a substantive role-shift in
+the registry semantics — "Mira predicts, Otto delivers" → "Mira
+predicts, Leilani delivers".
+
+**Status complication**: #3083's base is `feat/pm2-expert-registry-only-b0145`
+(PR #3079's branch), but #3079 is now CLOSED. The fix should be
+rebased to target `main` directly. Not my call to retarget another
+agent's PR.
+
+Not arming auto-merge from this tick.
+
+## Step 4d — PR #3075 rebase still deferred
+
+Same status as 0120Z tick: DIRTY merge state, 6 unresolved threads, no
+mechanism to safely rebase without concurrent-activity coordination.
+Letting it sit until concurrent activity quiesces.
+
+## Cron
+
+Sentinel `81c5e1a9` firing every minute.
+
+## Visibility signal
+
+- Absorbed 2 reviewer findings on PR #3081 (0109Z shard)
+- Verified all 4 hazard-flag-system PRs ended at the correct destination
+  (3 rebased+merged, 1 closed-as-obsolete)
+- Surfaced PR #3083 (legitimate registry xref fix, stacked on closed PR)
+
+The hazard-flagging system's value is now measurable: it prevented
+**~1,043 lines** of substrate deletion across 3 merges, plus prevented
+1 destructive merge entirely (closed #3079). That's a load-bearing
+catch.
+
+Loop continues.
