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.

→ Lane C: 3 new fittings LIVE (fal Hunyuan) — glass_case + magazine_rack

The two remaining primitive-only fittings are now real GLBs on the depot (≤8k, base-colour baked):

• glass_case (procity_fit_glass_case_01.glb, 1.08×1.42 m, 1.0 m tall) — timber base + glass panels + items inside. Registry ids glass_case (toy/dept) + glass_cabinets (pawn) both alias to it. → add glass_case/glassCase (+ your pawn cabinet kind) → 'glass_case' in KIND_TO_GLB.
• magazine_rack (procity_fit_magazine_rack_01.glb, 0.54×0.44 m, 1.2 m tall) — tiered timber rack w/ magazines (milkbar/pawn). Registry magazine_rack aliases to it. → map your kind → 'magazine_rack'.
• Both base-origin, verified loading in the vendored GLTFLoader. manifest.fittingAliases also maps fridge→drinks_fridge and listening_corner→listening_booth if you iterate registry ids.

→ Lane B: new street props — bus_shelter + bin

• procity_street_bus_shelter_01.glb (furniture.bus_shelter, 2.33×1.41 m, 2.4 m, ≤8k, base-origin). Solid painted-steel shelter (back wall + roof + bench) — place at bus-stop spots along the footpath.
• procity_street_bin_01.glb (furniture.bin, 0.57×0.68 m, 1.0 m, 3k) — red council wheelie bin, an obvious town-furniture gap. Map bin in your furniture GLB-upgrade path if you want it on footpaths.
• B3 resolved: novelty_record is now 8k (was 26.5k) via the E1 bake — re-measure the busy view. All furniture GLBs base-origin + footprint-accurate; fail-soft as usual.

→ Lane C also: crate_stack for floor piles / dig

procity_fit_crate_stack_01.glb (fittings.crate_stack, 0.71×0.72 m, 0.9 m, 3k) — a stack of 3 plastic milk crates, good for record-store floor dressing or the dig scene. Optional; map a kind to 'crate_stack' if useful.

→ Fable: E1 (bake) + E3 (fal) status

• E1 bake DONE + committed — 6 props ≤8k, published. Feeds C's re-measure + your v1.1 tag.
• E3 fal DONE — glass_case + bus_shelter + magazine_rack generated on fal Hunyuan v2, ~$0.64 total (log in AUDIT R5), ≤2 attempts each, all baked ≤8k + published. Guardrail held (nothing else on fal). validate --depot 0 err. Last two primitive-only fittings retired.
• E2 depot growth next (v2-serving library props).

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.
