From 09ab1917e0623b8b57008b3188e24e83fe0ed99d Mon Sep 17 00:00:00 2001 From: Poytr1 Date: Mon, 17 Aug 2026 21:47:00 +0800 Subject: [PATCH] fix(evals): publish a referee message when it is delivered, not when it is decided MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit `WerewolfGame.roomBroadcast` wrote the referee's post into the provider-visible thread the moment the message was DECIDED, while its platform ingress only entered the daemon with the NEXT wave. The referee decides a phase message from inside `applyEffects`, which the runner calls mid-cascade — peer turns woken by the effect that ended the phase are still open. Those turns could refresh their context onto a message the daemon had never delivered, act on the phase change, and have the reply charged to their PEER circuit: the trusted-human turn that resets the automatic loop-guard budget never happened, so a day's discussion and its votes piled onto one window and every circuit latched at MAX_AUTOMATIC_TURNS_PER_WINDOW. Whether an open turn caught the early write was pure scheduling, so a seven-seat scripted run forked between two whole games — latch-everything / six-round `round_limit`, or play-it-out / two-round `completed` — and the SCRIPTED BOUNDARY test flaked roughly one run in seven. `roomBroadcast` and `privateDelivery` now return thunks and `pendingWaves` holds them, so `nextDeliveries()` publishes the thread row, the world event, and the ingress as one atomic step at emit time. Each echo outcome also reports its room, so `peer.wake` records which circuit was charged. The SCRIPTED BOUNDARY test pinned the broken branch, and its premise was an artifact of the bug: seven seats never exhaust the budget once every phase arrives as a delivered referee turn. Rewritten as the complement of the twelve-seat test, asserting invariants instead of a magic number — nothing latches, no wake is gated, no player takes MAX_AUTOMATIC_TURNS_PER_WINDOW automatic wakes on one room's budget between two referee posts, only wolves are charged in the den, and every speech follows a DAY post while every vote follows a VOTE post. That last one fails directly if a referee message ever reaches an open turn early again. The sequential-day test's "later days are allowed to stall" allowance was conditioned on the same artifact and is now tightened to every day completing its order. Verified with 40 consecutive runs of the file (20 quiet, 20 alongside six concurrent `eval:collab:contracts` passes) — all green, and the seven-seat game is now byte-identical run to run.
