Record the 2026-09-29 re-measurement and the E-2/E-3 answers

E-3: the text lane adds 31 pp coverage at full resolution and 23 pp at live
while raising precision, against a +5 pp bar. E-2: LocalLane is RootSIFT-only,
so ORB/BRISK have nothing left to drop from the shipped path.

+**E-3 answered.** Removing the text lane from the decision, same crops and
+catalog, drops the local lane from 80% to 49% coverage at full resolution
+(91% → 79% precision, 5 → 8 false accepts) and from 66% to 43% at live
+(95% → 87%, 2 → 4). The lane adds 31 pp and 23 pp of coverage while *raising*
+precision, against E-3's +5 pp bar. It is not a veto-only lane.
+
+**E-2 answered.** `LocalLane` is RootSIFT-only; ORB and BRISK survive only in
+the `matcher` baseline lane, so there is nothing to drop from the shipped path.
+
+**Live path.** `_plan_classification` had lost its `in_flight` increment while
+a `label_frame_id` write was removed, so the guard never blocked, every frame
+re-planned the same tracks, and the executor queue grew until the server
+stopped answering. Restored. Label memory boxes now carry the shelf origin they
+were measured against and are shifted before the IoU test, so a pan no longer
+slides a stale box onto its neighbour. The text lane is resolved before the
+session lock is taken, removing a lock-ordering hazard against its build lock.

+Stream, 20 s pan, four runs: 71-79% coverage at 76-84% precision, against
+62-71% at 73-75% before. Still-image endpoint: 54 named detections in 2.2 s,
+against 41 before.

 Still open, and not implementable from here: Tier 2 held-out labels (F-11), the
-E-1..E-9 experiments, and the completion gate G1-G7, all of which need a second
-independent shelf visit.
