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.
