Each of the 19 ped rigs carried 1-9 primitives / 1-3 materials (fleet 92 draws,
~116 at the 24-rig near cap). merge_ped.py (Blender) merges each to 1 primitive +
1 atlased material: join meshes -> pack material UVs into a non-overlapping atlas UV
-> EMIT-bake base-colours into one 1024 atlas -> single material. Skinning + skeleton
preserved (65 joints, walk/idle untouched, clips retarget unchanged). Fleet 92->19
draws (1/ped); near-cap 116->24 (79% cut). Verified in vendored GLTFLoader: all 19
load as SkinnedMesh + bind walk; man_suit poses byte-identical to original. Hands to
Lane D (D1) for full validation + full-density numbers, then F flips the roster.

weld + meshopt simplify (--ratio 0.05 --error 0.12); skinning + skeleton preserved
(65 joints intact), walk/idle clips untouched, silhouettes clean at street distance.
Originals backed up to gitignored pipeline/.peds_orig/. Hands to Lane D (D2) for rig
validation; Lane F re-measures gate 3 (~24-rig cap × ≤3k ≈ ≤67k fleet).

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).
