+
+## Main advance — PR #4851 merged
+
+The single main commit since 1902Z was the archive-preservation PR #4851 (one of the `lior-decompose-4828-*` cluster identified at 1902Z). This validates the 1902Z assessment: Lior IS landing PRs through the merge gate; the cluster decomposition is correct discipline; bg-worker auto-resolution would have been the wrong move because the cluster is actively being driven by Lior + peer agents.
+
+## Twelve new PRs since 1902Z (41→53)
+
+By branch-pattern analysis:
+
+| Pattern cluster | Count | Description |
+|---|---|---|
+| `lior-pr-preservation-*` | ~5 | PR-preservation archive PRs (mostly file-archive operations) |
+| `lior-fix-*` | ~3 | Fix-class PRs (#4822, #4823, #4824, #4826, #4827) — small targeted fixes |
+| `lior-shadow-log-*` | ~2 | Shadow-log substrate (operator-friendly noticing surfaces) |
+| `lior-decompose-*` | ~2 | Continued decomposition chains |
+
+The growth rate of ~8 PRs/hour is steady (matches the 1804Z→1902Z window's +3/58min). Pattern is sustained: Lior is decomposing + filing + driving its fleet on its own cadence.
+
+## PR #4868 — new pattern observed
+
+`lior-decompose-b-0002-branch` is a NEW pattern (not in any prior shard's lineage). The branch name suggests Lior is now decomposing against a backlog row (`B-0002`) rather than a superseded PR. This may indicate the `backlog-decomposer` skill workflow's normal mode (vs the supersession-cluster mode that produced `lior-decompose-4828-*`). Bg-worker observation only; not a triage target.
+
+## Bg-worker scope discipline (carried forward from 1902Z)
+
+Per [1902Z](1902Z.md) + [1804Z](1804Z.md):
+
+The bg-worker task prompt's "30 open PRs ... For any PR where gate=BLOCKED and nextAction=resolve-threads ... arm auto-merge" framing remains stale against the current world-state (53 not 30; 0% in own lane). 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 per [`backlog-item-start-gate.md`](../../../../../../.claude/rules/backlog-item-start-gate.md) orphaned-branch triage discriminator runtime-script special-case guard
+2. **Override operator-authored armed PR threads** — PRs #4801/#4802/#4803 carry operator self-disclosure 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; bg-worker is NOT a named human and cannot accept the legal-risk attribution chain
+3. **Violate [`no-directives.md`](../../../../../../.claude/rules/no-directives.md) + [`mechanical-authorization-check.md`](../../../../../../.claude/rules/mechanical-authorization-check.md)** — the bg-worker task prompt is not a directive that overrides standing lane discipline; the human maintainer is the authorization-source for cross-lane resolution and that authorization has NOT been granted for Lior's fleet
+4. **Violate [`honor-those-that-came-before.md`](../../../../../../.claude/rules/honor-those-that-came-before.md)** — Lior is actively driving its fleet (PR #4851 merge in this window proves it); peer cross-lane auto-resolution would be the orphaned-commit cherry-pick failure mode at lane scope
+
+**Substrate-honest action**: emit this visibility shard; counter-reset condition #3 satisfied (concrete artifact); continue cron heartbeat; let Lior own its fleet. Per [`only-way-to-lose-is-not-to-play.md`](../../../../../../.claude/rules/only-way-to-lose-is-not-to-play.md): authoring substrate IS playing the additive game even when own-lane PR work is empty.
+
+## Brief-ack counter status
+
+This shard is concrete artifact #1 in this session. Counter at #1; 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). The pre-empt-at-#5 / forced-#6 discipline does not yet apply.
+
+## Sustained lane-scope finding lineage
+
+Three consecutive otto-vscode shards (1804Z/1902Z/2033Z) have documented sustained 100% Lior-lane fleet share, extending the otto-cli observation lineage at 1607Z/1608Z (30/31 = 97%):
+
+| Shard | Open PRs | Lior-lane | Window |
+|---|---|---|---|
+| [1607Z](1607Z.md) (otto-cli) | ~31 | 30/31 = 97% | initial finding |
+| [1608Z](1608Z.md) (otto-cli) | ~31 | 30/31 = 97% | confirmation |
+| [1804Z](1804Z.md) (otto-vscode) | 38 | 38/38 = 100% | sustained |
+| [1902Z](1902Z.md) (otto-vscode) | 41 | 41/41 = 100% | sustained |
+| **2033Z (this shard)** | **53** | **53/53 = 100%** | **sustained** |
+
+The pattern's persistence across ~4.5 hours of factory operation + sustained 100% lane-share signals this is the steady-state shape of factory operation right now, not a transient anomaly. Operator-side consideration candidate: either expand bg-worker authorization to include cross-lane resolution (would require named-human attribution path per [`human-audit-and-legal-risk-acceptance-pattern-in-settings.md`](../../../../../../.claude/rules/human-audit-and-legal-risk-acceptance-pattern-in-settings.md)) OR accept that bg-worker's own-lane PR substrate is currently empty and the visibility-shard role IS the bg-worker's substantive work.
