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.

// PROCITY Lane C — buy loop v0 (round 8). In-memory wallet: seeded starting cash, purchases, inventory.

// RUNTIME state only — reload resets, world generation is untouched (purchases never enter the plan or
|
||
// the seeded room build). One wallet is shared across dig sessions + shops so F's shell can render the
|
||
// same cash chip on the street. Economy is deliberately shallow (no persistence, no backend) — v0.
