Guesses on fair lanes.

B7.3 is the play path: how a guess becomes a scored result without the player ever holding the secret. A guess is six codes, validated against the game’s emoji set and guarded by a short-lived Valkey lock so one move charges once. It is charged on the room’s currency path inside a transaction — an all-pay rule, paid per attempt regardless of outcome — and only then appended as a branded job, carrying ids and the guess but no score and no secret, to the player’s lane. The bus serves the PLR lanes in rotation behind a starvation gate; the host never scores; one score worker reads the cached secret, computes the result, and records it. In a live room a scored event broadcasts at once; in a blind room the worker stays silent and the bank accrues until the close. Three dives: the guess and the lock, charged then enqueued, and fair lanes and the worker.
