Follow a ped into a shop and find them browsing. D owns occupancy truth; C owns browse points;
F wires the handoff. Validated end-to-end in-shell (?stock=real). qa --strict GREEN; v1 untouched.
Occupancy (D1): patronage records who's inside which shop by shopId. New
citizens.occupancyOf(shopId) -> {count, occupants:[{seed,enteredAt,pedIndex}]} (pedIndex = the
exact ped who ducked in, for identity continuity). Cleaned on emerge/chunk-drop/stream-toggle.
Deterministic: 17 shops + occupants byte-equal across two runs (fixed a stale-occupancy leak on
stream toggle).
Browsers: keepers.js gained browse:true (faces the shelf via ry, no player-greet) + pedIndex +
seedKey. Each = a merged ped ~1 draw. 12 enter/exit cycles: count == min(occupancy,3) 12/12,
worst 61 draws <=350 (C's headroom holds), leak-free (0 GPU delta after warmup), disposed every
exit via keepers.disposeAll().
Consistency (D2): inside peds hidden on the street (0 rendered), re-emerge at the door.
F handoff verified by running F's exact interior_mode wiring (enter -> occupancyOf ->
browsePoints.slice(0,min(count,3)) -> keepers.spawn). index.html setShops door points need
shopId:s.id added. Closing-time handled by the dwell model (pending A's explicit ruling).
Evidence: docs/shots/laneD/r9_browsers_in_shop.jpg. Changed sim.js + keepers.js + test page.
