D1: peds+keepers upgrade placeholder->rig in the shell; 12 enter/exit shops leak-free
(renderer.info.memory back to exact baseline); determinism holds across reload; ?noassets
fully placeholder with zero ped fetches.
D2 (gate-3 critical path): validated Lane E's decimated fleet — all 19 peds <=3k tris
(1564-2805, avg 2450), rigs bind+animate (skinning/skeleton preserved), 0 broken meshes under
eviction churn, silhouettes+identity intact, atlas bakes clean. Near fleet ~59.6k tris at the
24-cap (was ~1.2M) — F clear to re-measure gate 3.
D3: fixed a real bug found only in-shell — the impostor self-tone-mapped (toneMapped:false +
in-shader ACES), correct on the direct-canvas test page but DOUBLE-tone-mapped under the shell's
EffectComposer/OutputPass. Reworked to a standard toneMapped:true material outputting linear via
three's own tonemapping/colorspace chunks, so it matches the near rigs on both render paths.
setExposure is now a no-op (exposure is global). Verified noon+night in-shell.
Only web/js/citizens/impostor.js changed (+ NOTES/progress/R4 shots).

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).
