THE ROUND IN ONE MEASUREMENT (12 samples x 146 active, ?clips=0 vs default — a new flag that
turns off the library and nothing else): walking 99.3% -> 78.1% · bench-sit 0 -> 9.5% · lean
0 -> 7.1% · stopped in own idle 0.4% -> 5.1% · DISTINCT CLIPS ACROSS THE CROWD 4 -> 20.
The town was 99.3% people walking because standing still had nowhere to happen.
Wiring: new postures.js + clipbank.js. idles.glb (10/10) drives a per-citizen deterministic
idle on every near-tier actor plus the seeded shopkeeper. locomotion gives 33.7% of walkers a
shopping bag. sitlean (8/8, lazy) puts 4 sits on Lane B's ACTUAL benches and 4 leans on
shopfront walls. browse (5/8, lazy) is a real BROWSE state at C's browse points, seeded per
(shopId, slot). venue (5/6, lazy) widens the gig crowd, plus a publican pouring and a record
keeper in headphones. social (0/8) is never fetched — two-person conversation needs a paired
state machine, filed to R42.
Cost: boot = 4 requests, 1.24 MB / 16 clips resident; the rest lazy on first need; heap delta
+3.34 MB; mixer median 0.1 ms both arms. ?clips=0 / ?classic=1 / ?noassets=1 fetch ZERO clips
— not even clipbank.js (dynamic import). No shell edit needed.
DRAWS: +0 on every bookmark (street_noon 193, crossroads 108, night_crowd 128, market_square
94, night_neon 111, interior 110 — identical both arms). Ruling 4 respected exactly.
DETERMINISM: 150 citizens, two fresh contexts, byte-equal posture signature. Controls: seed+1
differs; EVERY clip GLB delayed 2 s -> identical signature (posture is a pure function of
(citySeed, id), never of residency). 6 new streams collide with none of the 12 pre-R41 keys.
TWO FINDINGS THAT CHANGED THE DESIGN: the idle pool was INVISIBLE — wired only to the R17/R29
node loiter, so only 0.8% of citizens were ever stopped; and the lean never fired at all (0 in
a 9 s run). Both moved to the patronage stride check. Bench stations are GATED not trusted:
14/14 derived stations coincide with real instanced geometry within 2 cm, and the control
(same stations offset 2 m) matches 0/14. Filed to B: one benchStops(plan) export retires the
mirror, and furniture.js puts the bench's front ALONG the street rather than facing the road,
contradicting its own comment.
Leak: +0 geometries, +1 texture over 6 enter/exit cycles. Goldens 157,647/157,647, 0x5f76e76.

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.

Populate the town at city scale, on budget, deterministic per-citizen identity:
- rigs.js — ported 90sDJsim rig stack: mixamorig canonicalisation so one shared
walk clip drives all 19 peds, head-bone height-normalise, feet-plant, pooled
near-tier actors with walk<->idle crossfade
- impostor.js — 4-yaw sprite-atlas baker + instanced billboards: whole mid crowd
in 1 draw call, tone-matched to the ACES near rigs
- sim.js — deterministic roster, footpath lanes off the street graph, near/mid/far
LOD with hysteresis + hard 24-cap, staggered mixer budget, time-of-day density
- placeholder.js — seeded low-poly box humanoids (frame-one population + ?noassets)
- keepers.js — one keeper per shop at the counter, idle + greet-turn
- 21 ped GLBs (byte-identical from 90sDJsim), citizens_test.html harness,
LANE_D_NOTES.md, 5 beauty shots
Verified in-browser: 200 citizens at max mixer 0.2ms (budget 2ms), near capped 24,
determinism holds (200 identities match seed), no T-pose, ?noassets crash-free.
Consumes Lane A plan.streets with zero adapter. Six adversarial-review bugs fixed
(non-deterministic fleet order, shared-resource disposal on pool eviction,
impostor colour-management).
