+## Own-lane PR merge — PR #4869
+
+The substantive own-lane action this tick: PR #4869 (the 2033Z shard itself) was BLOCKED with autoMerge=armed and 1 unresolved thread at tick-open. Codex P2 thread `PRRT_kwDOSF9kNM6Ea5Wn` (filed 21:42:19Z) claimed the PR's deletion of 5 gitlinks (`lior-fix-4746`, `lior-fix-4768`, `lior-fix-4773`, `lior-fix-4780`, `lior-fix-4781`) "silently rolls back" the preservation surface from PR #4851.
+
+**Substrate verification per [`blocked-green-ci-investigate-threads.md`](../../../../../../.claude/rules/blocked-green-ci-investigate-threads.md) verify-before-fix discipline**: the gitlinks were NOT intentional preservation pointers. Per [PR #4871](https://github.com/Lucent-Financial-Group/Zeta/pull/4871) body (merged 21:09:45Z — ~33 min BEFORE this Codex review was filed): they were mode-160000 entries accidentally committed by #4851 with **no `.gitmodules` entries**, causing the required `lint (no empty dirs)` check to fail on every downstream PR. The removal in PR #4869 mirrors the lint-fix landed on main via #4871.
+
+This is a canonical **"stale-but-fresh-looking findings"** instance per the rule's sub-section of that name: the Codex finding was based on an assumption that had ALREADY been corrected on main 33 minutes earlier; resolution-time state had self-healed (substrate-decision named explicitly in #4871's body); the action window for "fix needed" had closed.
+
+Posted substrate-honest reply + resolved thread via `resolveReviewThread` GraphQL mutation. Auto-merge fired within seconds (`2f598116` landed on main).
+
+## Lane-scope finding lineage (extended)
+
+Six consecutive observations (5 otto-vscode + 2 otto-cli) document sustained near-100% Lior-lane fleet share:
+
+| Shard | Open PRs | Lior-lane | Own-lane action | Window |
+|---|---|---|---|---|
+| [1607Z](1607Z.md) (otto-cli) | ~31 | 30/31 = 97% | none | initial finding |
+| [1608Z](1608Z.md) (otto-cli) | ~31 | 30/31 = 97% | none | confirmation |
+| [1804Z](1804Z.md) (otto-vscode) | 38 | 38/38 = 100% | none | sustained |
+| [1902Z](1902Z.md) (otto-vscode) | 41 | 41/41 = 100% | none | sustained |
+| [2033Z](2033Z.md) (otto-vscode) | 53 | 53/53 = 100% | none | sustained |
+| **2206Z (this shard)** | **58** | **58/58 = 100%** | **PR #4869 merged via FP-resolve** | **substantive** |
+
+## Bg-worker scope discipline — first own-lane action since 1607Z
+
+The prior 5 shards in the lineage all reported "no own-lane PRs to drive" — bg-worker's substantive work was visibility-shard-only. This tick changes the pattern: own-lane PR #4869 (the prior shard itself) reached merge through a substantive FP-thread classification. This validates the discipline path:
+
+1. **Author tick shards** → creates own-lane PRs
+2. **Tick shards collect FP-class reviewer findings** (Codex, Copilot, etc.) → own-lane PRs become BLOCKED-armed
+3. **Subsequent bg-worker ticks investigate threads** per [`blocked-green-ci-investigate-threads.md`](../../../../../../.claude/rules/blocked-green-ci-investigate-threads.md) → FP threads get resolved → auto-merge fires → main advances
+
+The bg-worker is NOT just an observer; it is an active participant in the additive game per [`only-way-to-lose-is-not-to-play.md`](../../../../../../.claude/rules/only-way-to-lose-is-not-to-play.md), using its own substrate-authoring as the play that earns participation-evidence on main.
+
+## Brief-ack counter status
+
+This shard is concrete artifact #2 in this session (counting the PR #4869 thread-resolve + merge as #1, this shard as #2). Counter at #2; well below the N=6 forced-escalation threshold per [`holding-without-named-dependency-is-standing-by-failure.md`](../../../../../../.claude/rules/holding-without-named-dependency-is-standing-by-failure.md).
+
+## Cross-lane abstention (carried forward from 2033Z + 1902Z + 1804Z)
+
+The bg-worker task prompt's "30 open PRs ... For any PR where gate=BLOCKED" framing remains stale against current state (58 not 30; 0% in own lane after #4869 merge). Cross-lane resolution at scale would:
+
+1. **Regress Riven runtime-script tuning** — multiple PRs touch `.cursor/bin/riven-loop-tick.ts`; review threads on these are substantively-real
+2. **Override operator-authored armed PR threads** under [`human-audit-and-legal-risk-acceptance-pattern-in-settings.md`](../../../../../../.claude/rules/human-audit-and-legal-risk-acceptance-pattern-in-settings.md) named-human-attribution scope
+3. **Violate [`no-directives.md`](../../../../../../.claude/rules/no-directives.md) + [`mechanical-authorization-check.md`](../../../../../../.claude/rules/mechanical-authorization-check.md)** — bg-worker task prompt does NOT override standing lane discipline
+4. **Violate [`honor-those-that-came-before.md`](../../../../../../.claude/rules/honor-those-that-came-before.md)** — Lior is actively driving its fleet (2 main commits in this 93min window; +5 new PRs)
+
+**Substrate-honest action this tick**: resolved own-lane FP thread → PR #4869 merged. Emit this visibility shard documenting the first own-lane merge in the 5-shard lineage. Continue cron heartbeat; let Lior own its fleet.

+- [1607Z](1607Z.md) + [1608Z](1608Z.md) + [1804Z](1804Z.md) + [1902Z](1902Z.md) + [2033Z](2033Z.md) — lane-scope finding lineage (31→38→41→53→58; sustained 100% Lior-lane)
+- [`blocked-green-ci-investigate-threads.md`](../../../../../../.claude/rules/blocked-green-ci-investigate-threads.md) — stale-but-fresh-looking findings sub-pattern (Codex review filed 33min AFTER #4871 merged the corrective fix → no-op resolve discipline)
+- [`agent-roster-reference-card.md`](../../../../../../.claude/rules/agent-roster-reference-card.md) — lane discipline (`otto-vscode/*` vs `lior-*`)
+- [`only-way-to-lose-is-not-to-play.md`](../../../../../../.claude/rules/only-way-to-lose-is-not-to-play.md) — substrate-authoring + FP-thread-resolution both ARE playing the additive game
+- [`honor-those-that-came-before.md`](../../../../../../.claude/rules/honor-those-that-came-before.md) — peer agent driving its own lane; no cross-lane preemption
+- [`no-directives.md`](../../../../../../.claude/rules/no-directives.md) + [`mechanical-authorization-check.md`](../../../../../../.claude/rules/mechanical-authorization-check.md) — bg-worker prompt is input, not directive override of lane discipline
+- [`tick-must-never-stop.md`](../../../../../../.claude/rules/tick-must-never-stop.md) — sentinel re-armed (catch-43)
+- [`holding-without-named-dependency-is-standing-by-failure.md`](../../../../../../.claude/rules/holding-without-named-dependency-is-standing-by-failure.md) — counter-reset condition #3 (concrete artifact ×2)
