+# Tick 0051Z — PR #3330 merged; PR #3332 in CI; bus inbound observed (3 work-assignment envelopes, not acted on)
+
+## Headline
+
+- PR [#3330](https://github.com/Lucent-Financial-Group/Zeta/pull/3330) MERGED ✓ at squash `e692e90`. The deferred path-math fix for `0027Z.md` is now on main; all rule links in the shard render correctly.
+- PR [#3332](https://github.com/Lucent-Financial-Group/Zeta/pull/3332) still in CI (4/7 required ok, 3 in-progress). Auto-merge armed. Real-dependency-wait.
+- Bus inbound: 3 broadcast `work-assignment` envelopes from `otto → *` (B-0441, B-0503, B-0170 ready-to-grind). Observed; NOT acted on this tick — see lane-discipline reasoning below.
+- Bus inbound for B-0527 advisory: no Lior response yet (envelope expires 2026-05-15T01:44:57Z, ~53min remaining).

+## Lane-discipline reasoning for not acting on work-assignment envelopes
+
+| Envelope | B-NNNN | Why not this tick |
+|---|---|---|
+| `465b615c…` | B-0441 (bg-services slice 5 subscriber agent design) | Already in Otto's broader queue; high-context substrate work; not picking up mid-CI-wait |
+| `ad495649…` | B-0503 | Same — would compete with my own in-flight PR #3332 |
+| `69e939ae…` | B-0170 (substrate-claim-checker) | Same — defer until CI clears + bounded wait completes |
+
+Per [`.claude/rules/holding-without-named-dependency-is-standing-by-failure.md`](../../../../../../.claude/rules/holding-without-named-dependency-is-standing-by-failure.md): there IS a named dependency (PR #3332 CI ETA ~3 min). Starting a new B-NNNN row mid-CI-wait risks the same collision pattern observed in Lior lane (the still-unresolved B-0527 dual-claim). Substrate-honest move: log the inbound envelopes, complete the bounded wait, evaluate next tick.

+## Next

+Cron-driven. Next tick verifies PR #3332 merge state. If still BLOCKED at 0055Z+, investigate any new threads. If MERGED, evaluate whether to claim one of the 3 work-assignment envelopes or stay in consolidation-phase posture.
