+## PROGRAM CLOSEOUT — 2026-08-08: all six slices COMPLETE, user-accepted
+
+Slices 5 and 6 closed together after the vendor arc's final gates. The
+complete retail vendor experience is live and user-verified end to end:
+walk-to-use from afar (the never-animated-target physics-host resolver +
+the cylinder-gap range watcher), the authored panel with the scrollable
+category dropdown (arrow-cap, downward, left-aligned), retail cost
+sentences with live purse repaint on every money change, per-unit and
+whole-stack pricing per the split-size mask, the MaxStackSize quantity
+slider with the right-justified count entry and two-line name wrap in
+the toolbar, staged buying (accumulate + 5000 cap + shop-row decrement +
+the four pre-send guards + the batched 0x005F + the X-close confirm),
+selling (Selling-tab drop target with drag-over auto-switch,
+InqAcceptability with verbatim rejection strings, BF_RETAINED, batched
+0x0060), double-click-to-buy (AP-171, user-approved modernization),
+prepend pack ordering (the cross-queue placement replay), and
+materialized shop objects with ownership-checked lifecycle + examine.
+
+Four adversarial Opus reviews found 34 defects before the user saw them;
+the user's connected gates found eleven more that only live sessions
+expose; two latent client-wide crashers (#348 cursor-handle exhaustion,
+#350 render-ledger overflow) were exposed, root-caused, and fixed along
+the way. Landed across `e45c95b0..af1a1ef9`. Deferred with issues/rows:
+#352 (range-watcher cylinder unit test), AP-166's pending-sell
+highlight, AP-167 (SellSingleItem's non-empty-container branch), AP-168's
+shop-stock half, Buying/Selling staging polish beyond the landed scope.
+
+This closes the pre-M4 world-interaction completion program.
