+# Tick 0109Z — stale-base destructive-merge hazard flagged on 3 PRs
+
+## Refresh
+
+`bun tools/github/poll-pr-gate-batch.ts --all-open` returned 5 open PRs.
+**3 new since last tick** were CLEAN gate / 0 unresolved threads / no
+auto-merge armed — surface signal said "ready to merge." Substrate-honest
+review of `git diff origin/main..<branch> --stat` revealed all three would
+DELETE substrate landed via PR #3074 (c671f36) + PR #3076 (8412805).
+
+| PR | Title | Branch | Author | Net delta if merged |
+|---|---|---|---|---|
+| #3077 | docs: archive PRs 3073, 3070, 3069 | `chore/lior-pr-preservation-2026-05-13` | AceHack (Lior agent) | +365 / **-379** (6 substrate files deleted) |
+| #3078 | docs: lior shadow lesson log for PR 3075 | `chore/lior-shadow-pr3075` | AceHack (Lior agent) | +13 / **-379** (6 substrate files deleted) |
+| #3079 | feat(pm2): add Mira to EXPERT-REGISTRY | `feat/pm2-expert-registry-only-b0145` | AceHack | +1 / **-285** (4 substrate files deleted); also obsolete — row already on main |
+
+## Substrate files at risk of deletion
+
+- `docs/EXPERT-REGISTRY.md` PM-2 / Mira row (landed via #3074)
+- `docs/backlog/P1/B-0145-...md` body content (landed via #3074)
+- `docs/forward-radar/TEMPLATE.md` (entire file; landed via #3074)
+- `docs/forward-radar/calibration.md` (entire file; landed via #3074)
+- `docs/hygiene-history/ticks/2026/05/14/0051Z.md` (entire file; landed via #3074)
+- `docs/hygiene-history/ticks/2026/05/14/0052Z.md` (entire file; landed via #3076)
+
+## Action taken
+
+1. Posted stale-base hazard comments on all 3 PRs:
+   - [#3077 comment](https://github.com/Lucent-Financial-Group/Zeta/pull/3077#issuecomment-4446452728)
+   - [#3078 comment](https://github.com/Lucent-Financial-Group/Zeta/pull/3078#issuecomment-4446453784)
+   - [#3079 comment](https://github.com/Lucent-Financial-Group/Zeta/pull/3079#issuecomment-4446454454)
+2. Each comment names the deleted files + lines, points to the substrate
+   commits, recommends rebase-on-main.
+3. **Did NOT arm auto-merge** on any of these PRs. CLEAN gate is a
+   surface signal; substrate-honest review of the diff is the substantive
+   check per `.claude/rules/algo-wink-failure-mode.md`.
+4. **Did NOT close** any of them — closing is the PR author's call.
+5. **Did NOT rebase** anyone else's branch — force-push to others' work
+   requires coordination not present in this tick.
+6. Released stale B-0145 + B-0456 claims (both PRs now merged or
+   advancing without my work).
+
+## Pattern observation
+
+The Lior agent (and possibly other agents) appears to be opening PRs
+from local branches without first pulling latest main. This is the
+exact failure-mode that `.claude/rules/claim-acquire-before-worktree-work.md`
+and `.claude/rules/refresh-before-decide.md` are designed to catch — but at the
+*open-PR* scope, not the *start-worktree-work* scope. Mechanization gap
+candidate: pre-PR-open hook that runs `git fetch origin main` + warns
+if the branch diverges from main by more than N commits.
+
+Filing as substrate observation; not a backlog row this tick.
+
+## Holding status
+
+- **#3074**: MERGED (c671f36) — verified
+- **#3075**: in CI re-run with 9bfdde9 (rename fix). 7 outdated unresolved
+  threads still block. Real-dependency-wait + future-tick batch-resolve.
+- **#3076**: MERGED (8412805)
+- **#3077**: hazard flagged, awaiting rebase or close
+- **#3078**: hazard flagged, awaiting rebase or close
+- **#3079**: hazard flagged + obsolete, awaiting close
+- **#3080**: this session's prior shard, CI in progress, auto-merge
+  armed; real-dependency-wait
+
+## Cron
+
+Sentinel `81c5e1a9` still firing every minute.
+
+## Visibility signal
+
+Caught a substrate-destruction risk that surface-level CI green would have
+hidden. 3 hazard comments posted, no destructive action taken. Next tick
+should re-poll: if any of these PRs have been rebased, re-evaluate; if not,
+the comments stand.
+
+Loop continues.
