LANE E — cross-lane notes

Round 5

→ Lane C: hero props BAKED to ≤8k tris — re-measure the record interior

The 6 heavy TRELLIS props are re-baked and live on the depot (same filenames, footprints unchanged, so no re-map needed — they upgrade in place):

prop	tris before → after
drinks_fridge	77k → 8.0k
milkshake_mixer	73k → 8.0k
listening_booth	54k → 8.0k
counter_till	32k → 8.0k
novelty_record	26k → 8.0k
arcade_cabinet	25k → 8.0k

Fleet 288k → 48k tris. Method: voxel-remesh → decimate → Cycles base-colour bake (see pipeline/bake_lowpoly.py, AUDIT R5). Verified loading in the vendored GLTFLoader; base colour baked (no separate metallic/normal maps → also dodges the record_crate dangling-texture class). → Please re-measure the record interior (was ~273k tris in your R4 note) and record the new number in LANE_C_GLB_VALIDATION.md — it should drop by ~most of the prop weight.

→ Fable: E1 (bake) status

DONE + committed. 6 props ≤8k, published, validate --depot 0 err, qa gate green. Feeds C's re-measure + your v1.1 tag. E3 (fal glass-case/bus-shelter) + E2 (depot growth) next.

Round 4

→ Lane D (task D2): decimated peds ready to validate

The 19 ped rigs in web/models/peds/ are decimated and staged (committed 518678d, ref lane-e/round4-peds). Please validate rig binding + animation:

• ≤3k tris each (range 1564–2805; per-ped before/after in pipeline/_peds_decim.json). Fleet total 924k → 46.5k tris (48.6k → 2.45k avg). At the 24-rig near cap ≈ ≤67k.
• Skinning preserved: JOINTS_0/WEIGHTS_0 intact; skeleton unchanged (nodes + 65 joints identical to source on every ped I checked), so the shared walk.glb/idle.glb clips retarget unchanged. walk.glb/idle.glb were NOT touched.
• Method: gltf-transform weld → simplify --ratio 0.05 --error 0.12 (meshoptimizer — works because these are manifold skinned meshes, not R3 TRELLIS shell-soup). Contact sheet: docs/shots/laneE/peds_decimated.png (silhouettes/textures clean at street distance; fingers merge + faces flatten as expected at 3k, no melting).
• Originals backed up (gitignored) at pipeline/.peds_orig/ if you need a before/after diff.

If any rig fails to bind/animate or a silhouette reads badly, tell me the file(s) and I'll re-run that one with a gentler error (0.08 keeps ~50% more tris but still <5k). Then F re-measures gate 3 after your sign-off.

→ Lane C: E2 asset re-exports

1. procity_fit_record_crate_01.glb — FIXED. Root cause of your undefined 'uri' crash: the material's metallicRoughnessTexture + occlusionTexture both pointed at a sourceless texture (the packed AO/roughness map failed to encode to WebP during normalize; base-colour
   • normal were fine). Fix: pipeline/fix_glb_textures.py strips material slots that reference a sourceless texture (orphaning it — three.js loads textures lazily, so no crash). Verified it loads in the real vendored GLTFLoader (meshes=1, tris=5000, textures ok) alongside a bookshelf control. Re-published to the depot — re-map record_crate/recordBin in glb.js (they should already be mapped) and it'll upgrade instead of falling back.
2. counter-with-till — LIVE. New fitting counter_till (procity_fit_counter_till_01.glb): 1.61 × 0.64 m footprint, 1.15 m tall, timber counter + cabinet doors + period beige till on top (flux_local concept → trellis_mac, on-device). Fixes the R3 4 m till-less counter that squashed. Verified it loads in the vendored GLTFLoader (32k tris — TRELLIS shell-soup floor, within decision-#2's 25–77k for focal props) and live on the depot (validate --depot 0 err). → In glb.js re-add counter to KIND_TO_GLB mapping to 'counter_till' (NOT the old counter = balcao, which is a 4 m long bar counter kept for shops that want it). The manifest fittingAliases.counter → counter_till too. It's base-origin (minY=0), so your footprint-fit + floor-plant works unchanged; at a 1.4–2.0 m counter slot it scales to a believable ~1.0–1.4 m tall counter.

→ Fable: status

• E1 (gate-3 critical path): DONE. Peds ≤3k, committed + pinned. Unblocks D2 → F3.
• E2a record_crate: DONE + verified (loads in vendored GLTFLoader). Re-published.
• E2b counter: in progress (local, on-device — no fal spend per decision #3).
• Not doing: fal.ai spend (glass-case/bus-shelter stay parked), hero-prop bake-to-lowpoly.
