C1 — buy loop v0 (new wallet.js): runtime-only economy — seeded cash
(~$60–200), buy()/broke-gate/in-memory bag, onChange for a cash chip.
World gen untouched (purchases never re-enter the plan/seeded build).
Test page: #cashChip HUD + I-toggle inventory + dig BUY IT button
(pull → bag, cash down, bin depletes); digSoak buys ≤2/visit.
C2 — book spines + toy boxes wired to ?stock=real. stockpack.js keys
each pack to a slot (record→sleeve, book→spine, toy→box); stock.js
shelfLine builds real atlas-UV cover planes for book/toy shelves
(static, no dig), fail-soft per pack. E's packs live: record 350/6,
book 311/4, toy 273/5 (items/atlases).
C3 — validated: draws ≤350 (record 41, book 42, toy 51), determinism
0 fails, leak-free (0 geo/tex delta ×20; buy-soak 12 visits/5 bought,
leakGeo0/tex0), reload resets wallet, flag-off + ?noassets untouched,
qa.sh --strict GREEN 5/5. Shot: docs/shots/laneC/buyloop_r8.jpg.

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).

Review debt: book room was 1,245 draws GLB-on. Diagnosed two drivers —
multi-material stock boxes (one draw per face, 6x) and one mesh per stock
item — then batched:
- stock.js: stock boxes are single-material now; every stock mesh tagged
userData.isStock.
- batch.js (new): batchRoom() two-tier merge, called from interiors.js before
the GLB upgrade. Room-level merge of all isStock across every fitting
(grouped by material, world transforms baked) + per-fitting merge of fixture
frames (kept in-group so record bins stay raycast targets for ?dig=1 and the
GLB upgrade can hide the fixture). Uses vendored BufferGeometryUtils
mergeGeometries.
- glb.js: frame-hide is now by isStock tag (not frame-count), so batched
fixtures hide while the room-level stock rides on the GLB.
- interior_test.html: drawSweep() asserts <=350 draws across all type x
archetype (GLB off and on), folded into the soak; exposed as
window.PROCITY_C.drawSweep for F's harness (hook in LANE_C_NOTES).
Result (drawSweep, seed 1990): GLB-off worst 152, GLB-on worst 313
(opshop/hall) — book 1,245 -> 189. Determinism 0 fails / 810, leak-free, dig
still riffles batched bins, worst warm build 38ms (<50), visually identical.
qa.sh --strict GREEN (5 gates).
