 - Open items for later cycles: worker A's 8 untracked src/ files awaiting
   in-flight/stale classification; worker C recommends excluding the primitive-init
   family remainder (`0x80012A10`/`0x80012AE0`) from re-chartering.

+## Worker rotation (recorded 2026-09-24, cycle 2)
+
+- Worker B (`01a0d180-efdd`) flagged BUDGET: exhausted mid-cycle-2 with an honest
+  `0-for-5` report — five near-matches in four known classes (0x80036A9C 1 byte,
+  0x800F50B0, 0x800496CC, 0x80103AA4, 0x80102FE4 retry confirmed residue is
+  allocation not macro form). Handoff complete: no unclaimed work, no drafts in
+  src/, report.tsv with 18 entries, and four named cheap closes for fresh
+  context (0x80036A9C, 0x800F50B0, 0x800496CC, 0x80103AA4).
+- **Pool observation ACCEPTED as the standing instruction**: remaining tier-1
+  residue is dominated by allocation/operand-order tie-breaks (lowest yield per
+  attempt); the volume is in tier-2 call/frame bodies. Workers pointed at
+  tier-2.
+- Replacement: pane-open surface unavailable (three sessions already in the
+  cwd; intercom reuses rather than spawns). Per the plan's designed fallback,
+  **the coordinator absorbs worker B's partition** (`.run/p9/worklist-b.tsv`).
+- B's 13 promoted claims stand; B remains available for the P9-T5 review.
