raffle/v4 package

SweepDrawlessWeek rolls a FINISHED week's sponsorship forward into the live week's pot, when nobody ever bought a ticket in it. PERMISSIONLESS, like Commit.

THERE ARE TWO SWEEPABLE SHAPES SINCE 2026-09-29 AND THE SECOND HAS A CLOCK ON IT: a week with NO TICKETS AT ALL (the original drawless week, sweepable as soon as it is over) and a week with TICKETS BUT NO SPEND — every entry earned by duel play — which is sweepable only once it is committed and refundGraceElapsed has gone true, and which is marked Abandoned when it is. The full reasoning, including why "zero spend" alone would have been a fund-destroying gate, is in the body above the shape test. AUDIT-2026-09-28.md finding 17.

FINDING 15 MADE THIS FUNCTION MUCH HARDER TO REACH AND IT IS DELIBERATELY KEPT. A week of duel rake used to end with sponsorship and a zero ticket total, which is exactly the state this function exists for. Now the duel's deliveries bring ENTRIES with them (FundPotWithEntries), so such a week normally has tickets, is a real draw, and this function correctly refuses it — its sponsorship is a prize somebody can win rather than money nobody can reach. The states that still land here are real and small: a rake too small to buy one whole entry (rake < EntryUnitPrice), a duel both of whose parties played from realm code and so earned nothing, and any plain FundPot sponsorship from a caller that is not the duel. DO NOT DELETE IT ON THE GROUNDS THAT THE COMMON CASE IS GONE: every one of those states still strands money without it, and that was the sixth of this product's "money in, no way out" findings.

THE DEFECT IT CLOSES. FundPot credits the live week and creates that week's record if it does not exist yet, so a week in which duels were collected but nobody ever bought a raffle ticket ends the week holding sponsorship in a Draw with a zero ticket total. Commit rightly refuses that week (no tickets, no unit to draw, no owner to pay), Resolve and Refund both require Committed, and FundPot only ever funds the live week — so before this function that sponsorship was unreachable by EVERY path in this realm, permanently, while heldPots went on counting it and checkInvariant and AuditFailure stayed green over money that was gone. That is the same class of defect as the 2026-09-28 audit's first and most serious finding, and it is not an exotic state: a quiet raffle week with an active coin flip is an ordinary Tuesday.

WHERE THE MONEY GOES, AND WHY NOT opsPot, AND WHY IT DOES NOT GO ANYWHERE AT ALL. It goes BACK TO THE PEOPLE WHO HOLD UNITS IN THIS WEEK, pro rata — and for shape 1, which has no unit holders whatsoever, it goes to opsPot because there is provably nobody else. Read retireSponsorship; the branch this function takes is exactly `pureEarned` and is stated again at the call site. This money is the PLAYERS' side of the duel rake (see r/splash/arcade/duel's Collect: the ops share went to r/splash/ops already, and what arrives here is deliberately the rest), so on shape 2 it lands back on the duel players who generated it.

TWO SENTENCES THIS REPLACES, IN ORDER, BECAUSE THE SEQUENCE IS THE LESSON. First: "So it rolls forward to the live week's pot" — the live week being whichever week the caller chose to fire in (finding 28). Then: "It marks the week and registers it (markCarryPending); the next week record to be created absorbs it at its own birth... to a week nobody in this transaction can name" — except that the caller who opens that week is the caller who calls Buy, so they could name it after all, and be its only entrant (finding 31). Both sentences described a destination. There is none now.

AND REFUND NOW AGREES, WHICH IT DID NOT UNTIL 2026-09-29. This paragraph used to end "Contrast Refund, which moves an abandoned week's sponsorship to opsPot: there the week HAD entrants and they are being paid back individually, so there is no prize left for the sponsorship to enlarge." THE CONTRAST WAS THE DEFECT. Two functions in one file moved the same field's money to opposite destinations, and since earned entries exist an abandoned week's "entrants" are mostly duel players with no spendOf to be paid back at all — so the rationale did not hold either. One ticket plus the grace window turned the whole argument into a cheap transfer of a week of rake to the house. AUDIT-2026-09-28.md finding 16. Refund's transition now retires the sponsorship exactly as this function does, and retireSponsorship is the shared step — a step with no destination in it.

THIS FUNCTION STILL DIFFERS FROM REFUND IN ONE WAY, AND MUST, BUT THE DIFFERENCE IS NOW A CLOCK RATHER THAN A DESTINATION. It may REFUSE — the live-week rule, the shape tests, and the grace window each shape must wait out — because a dead week's sponsorship has no claimant and no deadline, so a refusal costs nobody anything and any caller may retry for ever. Refund may not refuse, because a buyer is waiting; and since neither function looks for a destination any more, there is no longer any state in which Refund COULD be refused for want of one. That is strictly stronger than both fallbacks it replaced — the immediate opsPot bank of finding 16 and ReclaimStrandedCarry's three-week long stop of finding 28 — and both of them are now deleted rather than relocated, because a claim on the week the money is already in cannot fail to find anything.

THE DESIGN TENSION, RESOLVED EXPLICITLY SO IT IS NOT "FIXED" BACK. This realm's stated principle is that THERE IS NO ROLLOVER, so a drawless week must not exist — and Commit still enforces exactly that, unchanged. That principle is about TICKET HOLDERS' pots: it stops a week's prize being deferred away from the people who entered that week and paid for it. Rolling SPONSORSHIP forward from a week that had no entrants whatsoever does not violate it, because there was nobody to defer anything away from — no ticket was sold, so no buyer's expectation of this week's prize exists to be broken. Do not "restore consistency" by deleting this function or by letting Commit accept a zero total; the second would reopen the drawless-draw hole, and the first would reopen the stranded-money hole.

NO WUGNOT MOVES HERE, and a reader looking for the missing Transfer should stop looking. The tokens are already inside this realm — FundPot pulled them in when the dead week was sponsored — so this is PURE BOOKKEEPING between two weeks of the same realm. The realm's wugnot balance is identical before and after; heldPots and heldSponsored each lose and regain exactly the same amount, which is why checkInvariant's equality still holds at the end.

Panics if the week is not over yet (a live week may still sell a ticket, which would make it a real draw), if there is no record for it, if anybody BOUGHT a ticket in it, if it holds no sponsorship, if it is resolved or already abandoned, if its entries are all earned and its draw can still happen (uncommitted, or inside the grace window), or — defensively — if a ticketless week is somehow committed.
