godbayHammer(entry, townKey): THE ONE-HAMMER LAW — seeded by ITEM IDENTITY
(godbay:<townKey>:<sku|slotId>:<dayFound>:<pricePaid>), NEVER by resolution day: a passed-in
item re-lists to the same result forever, so there is no retry farm anywhere in the economy
(the keeper's offer is a formula, the auction is one hammer per item per life). Fixed 4-draw
stream. Rolls: 15% passed in (comes home free) · hammer uniform across the item's band
(grail's open top = 2×low; unbanded alpha finds auction around pricePaid — honest, never
invented) · 12% bidding war ×1.5–2.0 · 12% commission, net floor $1. EV ≈ 0.8× band midpoint
— UNDER the asking-price EV of in-band stock: random flipping bleeds, only FINDS profit
(charter law #2 at the auction house); the keeper's half-of-low stays the instant floor, the
gavel the bounded ceiling (2×high×0.88). Band table imported from C's bible.js and PRNG from
core/prng.js — one authority each, no mirrors.
listings: optional on procity-save/1 (entry shape + listDay ≥ 1, the pulls/wants back-compat
law). listFind (identity — the entry LEAVES the crate, it cannot also sell at a counter) ·
resolveAuctions() runs in adopt() AND sleep(), so sleep, travel, and day-moving imports all
hammer what they pass · takeAuctionNews() drains the transient morning paper (NOT saved — the
ledger is cash/collection; the paper is a toast).
save.js: optional wants:[{artist?|title?|sku?}] on procity-save/1 (validated exact-and-loud,
≥1 string field per entry, cap 40, absent-when-empty — the same back-compat law as pulls).
recordWant (case-insensitive dedupe) / findWant (a want covers an item when every field the
WANT names matches) / removeWant (identity). TRAVEL in adopt(): the adopted save's town !==
this boot's townKey (town OR seed — a new seed is a new town) ⇒ day += 1, traveled = true,
prunePulls — load AND import both pay the fare; same-town adoption is FREE, so reloads and
export→import round trips keep the save-determinism gate's byte equality untouched. The 23
towns are a map you spend days crossing now, not a dropdown.
interior_mode.js: onWant/isWanted seams into dig.open; buying a matching item clears its want
('✓ off the wantlist'). THE RUMOR (charter #6 — the keeper finally gossips): seeded
xmur3('rumor:citySeed:shopId:day') → ~45% of shop entries mutter a hunted want + a real
cached town in the banner. Runtime-only stream, freshly keyed — A's rotation boundary holds;
no game / empty wantlist ⇒ the line never exists. Full persona lines stay D's for the v6
clip epoch; the banner is the keeper's voice until then.
save.js: optional pulls: string[] on the SAME schema (validated exact-and-loud when present;
absent on every alpha save — old savers drop it silently, never reject; payload omits it when
empty so the alpha byte shape survives). recordPull/pullsFor seams; pruned on sleep/import —
day-tagged keys from other days are unreachable by construction (the consumer embeds the
current day), untagged keys are real-sourced and KEPT (sold means gone, tier-2 spirit at
tier 1). Cap 600 FIFO (delta law: saves stay tiny). Collection entries gain optional band
(recordFind stamps dig + shelf buys) — C's §9.1 sell basis reads it.
interior_mode.js: pull keys ${shopId}|${binKey}${pullTag}#${slot} — pullTag @d<game.day> for
rotating crates INCLUDING day 1 (the SEED stays untagged per the day-1 convention; the ledger
doesn't — a day-1 pull must not survive into day 2's identical-looking untagged key space),
'' for real-sourced (their pulls never expire). The seed input to binSeed is UNTOUCHED — A's
rotation boundary holds. Selling an item does NOT restock the bin (pulls are independent of the
collection — the leak the §30.6 filing predicted). digOffers getter = the honest-gate surface
(index/ask/band/sku) so the bible gate asserts identity, not looks.
