Lane C R7 C1: ?stock=real — real GODVERSE sleeves in the crates

The stockAdapter seam built in v1 finally eats. Lane E's stock pack (parody-
transformed Discogs metadata + cover atlas) feeds record-shop bins + the dig
riffle behind ?stock=real. Economy stays a stub (buying = toast).

- Contract handshake (task 1, unblocked E): confirmed E's index schema as-is
  in LANE_C_NOTES (items[{id,title,artist,price,price_band,atlas,uv}]; uv
  origin top-left, C flips V for WebGL; fail-soft; per-type packs).
- stockpack.js (new): preloadStockPack/getStockPack (cached) + makeStockAdapter.
  Atlas texture + material are shared/cached (like depot GLBs); each sleeve is
  a cover PLANE sampling the atlas at its baked UV, so all real sleeves in a
  room batch to ONE draw (record: 59 draws).
- stock.js binFan: real cover planes (else parody canvas). dig.js: riffles real
  covers, pull card shows title/artist/$price/band. interiors.js: opts.stock=
  'real' wires the adapter (warn-once + parody fallback if pack absent). Test
  page reads ?stock=real, preloads record/book/toy, passes the adapter to the dig.

Validated (E's staged 24-sample; real covers drop in unchanged when E gets the
DB): determinism 0/30, leak-free rooms + real dig (0/0 over 25 cycles), draws
<=139 all rooms (record 59), fail-soft on no-pack types, ?dig=1&stock=real
leak-free. Flag-off + ?noassets untouched (procedural path byte-identical).

+## Update 2026-07-14 (round 7) — `?stock=real`: real GODVERSE sleeves in the crates
+
+Round-7 §Lane C: the `stockAdapter` seam built in v1 finally eats. Lane E's GODVERSE stock pack (parody-
+transformed Discogs metadata + cover atlas) feeds record-shop bins + the dig riffle behind `?stock=real`.
+- **Contract handshake** (task 1, unblocked E): confirmed E's index schema as-is in
+  [LANE_C_NOTES.md](docs/LANES/LANE_C_NOTES.md) — `{ items:[{id,title,artist,price,price_band,atlas,uv}] }`,
+  UV origin top-left (C flips V for WebGL), fail-soft, per-type packs.
+- **New `stockpack.js`**: `preloadStockPack`/`getStockPack` (cached) + `makeStockAdapter`. Atlas texture +
+  material are shared/cached (like depot GLBs); sleeves are cover PLANEs sampling the atlas at each item's
+  baked UV → all real sleeves in a room **batch to one draw** (record: 59 draws).
+- **Consumers**: `stock.js binFan` builds real cover planes (else parody canvas); `dig.js` riffles real
+  covers and the pull card shows **title / artist / $price / band**; `interiors.js` wires `opts.stock='real'`
+  through the seam (warn-once + parody fallback if the pack is absent); test page reads `?stock=real`.
+- **Validated (sample 24-pack)**: determinism 0 fails/30, leak-free rooms AND real dig (0/0 over 25 cycles —
+  atlas shared, sleeve geo disposed), draws ≤139 all rooms (record 59), fail-soft on no-pack types (opshop
+  ok → parody), `?dig=1&stock=real` leak-free. Flag-off + `?noassets` untouched (procedural path byte-identical).
+- Built against E's **staged sample** (real index format, synthetic covers); real Discogs covers drop in
+  unchanged when E gets the DB (external — John/Fable). Shot: [stock_real_r7.jpg](docs/shots/laneC/stock_real_r7.jpg).
+
+**→ F**: new smoke for your strict harness — `?stock=real` enter record shop + open dig → assert real
+(non-parody) sleeves; the record bin's real sleeves are cover planes with `userData.isStock` on a shared
+atlas material (drawSweep stays ≤350). Hook + adapter in LANE_C_NOTES.

 # LANE C — cross-lane notes (PROCITY-C)
 
+## → Lane F: `?stock=real` smoke for the strict harness (round-7 C1 landed)
+
+`?stock=real` is wired (record shops; book/toy fail-soft if E ships those packs). Smoke recipe:
+- Preload once: `import { preloadStockPack } from interiors.js; await preloadStockPack('record')`.
+- Boot `?stock=real`, enter a record shop, **assert real sleeves present**: a real sleeve is a `Mesh`
+  with `userData.isStock`, geometry `PlaneGeometry`/`BufferGeometry` (batched), on a shared **atlas**
+  material (`material.map` = the pack atlas, not a per-item canvas). Simplest assert: after build,
+  `let n=0; room.group.traverse(o=>{ if(o.userData?.isStock && o.material?.map) n++ }); assert n>0` — with
+  the pack loaded the record bins' sleeves batch to **one** atlas mesh (parody canvas would be ~6 card
+  meshes). Or open the dig (`?dig=1&stock=real`) and assert a pulled sleeve's panel title is a pack title.
+- **Fail-soft**: pack missing → parody canvas + one `console.warn` (no throw). `?noassets` unaffected.
+- **drawSweep still ≤350** with `?stock=real` (record 59 draws — the atlas batches all sleeves).
+
+## → Lane E: stock-pack contract CONFIRMED (round-7 C1) — build the real pack to this, unchanged
+
+Your proposed index schema is good — **confirmed as-is, no field changes**. Building `?stock=real`
+against your staged 24-sleeve sample now (`web/assets/models/stock_record_{index.json,atlas_00.webp}`);
+the real covers drop in unchanged. The contract C consumes:
+
+```jsonc
+// stock_<type>_index.json   (type ∈ record | book | toy ; record is the acceptance bar)
+{
+  "version": 1,
+  "atlas_px": 2048,
+  "cell": 256,                                  // informational; C reads uv, not cell
+  "atlases": ["stock_record_atlas_00.webp", ...],   // 1+; may be depot: or assets/models/ resolved
+  "items": [
+    { "id": "rec_0000",
+      "title": "Neon Suburbs",                  // parody-transformed (no-real-trademarks law applies to metadata)
+      "artist": "Trev Wollemi",
+      "price": 39,                               // integer dollars — C shows "$39"
+      "price_band": "collector",                 // bargain|standard|collector|grail — C may tint the sticker
+      "atlas": "stock_record_atlas_00.webp",     // which entry in `atlases`
+      "uv": [0.0, 0.0, 0.125, 0.125] }           // [u0,v0,u1,v1] cover rect, ORIGIN TOP-LEFT
+  ]
+}
+```
+
+Agreements / who-does-what:
+- **UV origin is top-left (image-natural) — C flips V for WebGL** (`v_gl = 1 - v`). Keep your index
+  image-natural; the consumer handles the flip. (Sample verified against this.)
+- **Resolution**: C loads `stock_<type>_index.json` from a base (default `assets/models/`, i.e. your
+  staged path — same-origin, works offline). Atlas filenames in the index resolve against the same base;
+  if you publish atlases to the depot, give me a `"depot": true` flag or depot-prefixed names and I'll
+  route through the `depot:` loader. For now the sample loads local.
+- **Seeded pick per bin is mine** (same `shop.seed` → same crate contents). I only need *enough* items —
+  24 repeats across bins (fine for testing); the 300 pack fixes variety.
+- **Batching**: because every sleeve samples one shared atlas material (per-item UV baked into geometry),
+  all real sleeves in a room merge to **one draw** — the ≤350 law holds. Please keep it **one atlas per
+  pack** where you can (or few); each extra atlas = one more draw.
+- **Fail-soft**: index/atlas missing or `?stock` off → parody canvas (warn once). `?noassets` untouched.
+- **Per-type packs**: name them `stock_book_*`, `stock_toy_*` if you build them; I key by shop type and
+  fail-soft per type, so record-only is fine — book/toy are a bonus.
+
+You flagged needing a Postgres DSN (from John/Fable) to swap synthetic covers for real Discogs images —
+that's external and **does not block my consumer**; ping me only if the schema needs to change.
+
+
+
