Fable (integrator): ROUND 34 CLOSED — GODBAY hammers, all green; v7.0 needs only the first five minutes

qa.sh --strict --matrix: 7 passed · 0 failed · 0 warn · 0 skipped, MATRIX 10 towns green. New
STRICT smoke_godbay: consigned through the real crate DOM · ONE-HAMMER determinism (a frozen
pre-sleep export slept twice lands byte-identical — the seeded gavel, measured not trusted) ·
honest bounded resolution (net $19 ≤ 2×$24×0.88) · the wake toast carried the morning paper ·
the ride to melbourne hammered a listing on arrival · ?game=0 has no crate to list from · 0
console errors. Money shots in docs/shots/v7_beta/ (the dawn paper + the ⚖ crate). The full
v7 loop now closes end to end: dig the gem → keeper cash now or the gavel tomorrow → the
wantlist points at another town → the ride costs a day and hammers your listings on arrival.
Remaining for the v7.0 tag: THE FIRST FIVE MINUTES (onboarding), the tour, docs freeze — and
John's hands on the whole thing.

+  (`godbay:<townKey>:<sku|slotId>:<dayFound>:<pricePaid>`), never by resolution day — a
+  passed-in item re-lists to the same result forever, no retry farm. Fixed 4-draw stream. Rolls:
+  15% passed in (comes home free) · uniform hammer across the band (grail 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×mid — under in-band asking EV, so random flipping
+  bleeds and only FINDS profit; the keeper's half-of-low stays the instant floor, the auction
+  is the gambler's ceiling (bounded 2×high×0.88). PRNG imported from core/prng.js; the band
+  table imported from C's bible.js (one authority — no mirror after all).
+- `listings` optional on procity-save/1 (entry shape + listDay, same back-compat law).
+  `listFind` (identity, entry leaves the crate — can't also sell it) · `resolveAuctions()` runs
+  in adopt() AND sleep(): 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).
+- **hud.js:** ⚖ LIST on crate find rows (mail-in consignment) + AT AUCTION section; rebuild
+  watches listings. **index.html:** the wake toast and the arrival toast fold the paper in.
+- **Gate `smoke_godbay` (STRICT):** consign through the real crate DOM → save carries it ·

+  honest resolution (SOLD net $19 on a standard record, ≤ 2×24×0.88) · the wake toast carried
+  "⚖ SOLD Cane Toad Blues — hammer $22, $19 after fees" · the ride to melbourne hammered a

+# PROCITY — Round 34 instructions (from Fable, integrator)
+
+Date: 2026-07-20 · **R33 closed all green** — every v7.0-beta system is built. Round 34 opens
+**the v7.0 close: GODBAY, the offline auction** ([V7_THE_GAME.md](../V7_THE_GAME.md) system #4:
+"list an item, a SEEDED offline auction resolves NEXT DAY — the come-back-tomorrow hook").
+Offline tier FIRST per the proven ladder (G3's live rails are v7.x; this round is the seeded
+brain in the game layer, G's later live tier must match these laws). Solo round (John's "keep
+rolling").
+
+## The laws (GODBAY v0 — named now, gated below)
+
+1. **Mail-in consignment.** You list from THE CRATE (⚖ LIST on a find) — the 90s answer
+   (classifieds + the post). The entry leaves the collection into `listings` (you cannot also
+   sell it at a counter), `listDay` stamped. Resolution happens when the day moves past
+   `listDay` — sleep, travel, or a day-moving import all count (adopt() and sleep() both run
+   the resolver).
+2. **THE ONE-HAMMER LAW (no retry farming).** The hammer is seeded by ITEM IDENTITY —
+   `godbay:<townKey>:<sku|slotId>:<dayFound>:<pricePaid>` — NOT by the resolution day. A
+   passed-in item re-lists to the SAME result, forever. There is no re-roll anywhere in the
+   economy: the keeper's offer is a formula, the auction is one hammer per item, per life.
+3. **The house always eats.** Hammer rolls uniform across the band (grail's open top = 2×low);
+   ~12% chance of a bidding war (×1.5–2.0); ~15% passed in (returns to the crate, free);
+   12% commission, net floor $1. Expected value ≈ 0.8× band midpoint — UNDER the asking-price
+   EV of in-band stock, so random flipping bleeds and only FINDS profit (charter law #2's
+   spirit at the auction house: growth bounded by finds, the keeper's instant half-of-low
+   remains the coward's floor and the auction the gambler's ceiling — bounded at 2×high×0.88).
+4. **Delta law / classic purity unchanged.** `listings` is an optional procity-save/1 field
+   (same back-compat law as pulls/wants); no game layer ⇒ no listings, no DOM, no news.
+5. **The morning report.** Resolution queues transient news ("⚖ SOLD 'Sunburnt' — hammer $38,
+   $33 after fees"); the shell folds it into the wake/arrival toast. News is NOT saved — it's
+   the morning paper, not the ledger (cash/collection already carry the truth).
+
+## Gate (F): `smoke_godbay` (STRICT)
+
+List through the real crate DOM (C → ⚖ LIST) → entry moves collection→listings, the save
+carries it · sleep → resolved: listings empty, cash+net OR item returned, news queued, net
+within [1, 2.2×bandHigh] when sold · DETERMINISM: a pre-sleep export imported twice sleeps to
+byte-identical cash/collection both times (the seeded hammer, measured not trusted) · travel
+resolves too (list → ride to melbourne → resolved on arrival) · `?game=0` builds zero ⚖ DOM ·
+0 console errors.
+
+## ROUND CLOSED (Fable) — ALL GREEN
+
+`qa.sh --strict --matrix` on the final tree: **7 passed · 0 failed · 0 warn · 0 skipped**,
+MATRIX 10 towns green. `smoke_godbay`: consigned through the real crate DOM (collection 2→1,
+listDay stamped) · ONE-HAMMER determinism (a frozen pre-sleep export slept twice → byte-
+identical) · honest bounded resolution (SOLD net $19 on a standard record, ≤ 2×$24×0.88) ·
+the wake toast carried "⚖ SOLD 'Cane Toad Blues' — hammer $22, $19 after fees" · the ride to
+melbourne hammered a listing on arrival · `?game=0` has no crate to list from · 0 console
+errors. Design note vs the brief: the band table is IMPORTED from C's bible.js and the PRNG
+from core/prng.js (one authority each — the drafted mirror died in review). Money shots:
+`docs/shots/v7_beta/godbay_morning_paper.png` (dawn day 2, the paper in the toast, the crate's
+⚖ row) + `godbay_at_auction.png`. Full record: LANE_F_NOTES §34.
+
+**What remains of v7.0:** THE FIRST FIVE MINUTES (onboarding — arrive with a want, three
+toast-beats) · the tour ("day one to first gem") · docs freeze · the tag. Then John's playtest
+charters what's next.
