The third release from the audit; nothing a player sees changes. CHANGELOG has the detail.
The 0.4.9 playtest line is no longer maintained (Jesse, 2026-09-29): the deploy rule that
existed for it is gone and #85 is moot. The table test (#39#35 #42a #40) is closed — every
line of the checklist was met at a table. #46 is done and cannot regrow: the 36 unused
declarations are removed and `noUnusedLocals`/`noUnusedParameters` are on; two of them were
dead bot functions from rejected candidates the round said it had deleted. The documents no
longer teach `trainCapSlack` (a knob that throws), point at `as-built.md` (deleted in 0.8.2),
model `officeType` (the engine says `tier`) or describe `collisionOccurred` (never emitted);
the README's account of bot flags now matches the bot's. Five playtest saves committed in
`docs/` against the repository's own rule are in the ignored `playtests/`.
What the audit found and did not fix is written down as TODO #112-#117, each with its reason.
#112 is `docs/plans/structure.md`, the proposal for `http.ts`, `main.ts` and `check`. #117 —
`/api/save` hands a seat the seed mid-game — waits on a conversation.

Seven rules faults and one dealing fault, from a four-way code audit (engine, server,
client, tests) read against the code before anything was acted on. Each is pinned by a
test that failed first. CHANGELOG has the reasoning; this is the list.
THE DEAL. 0.8.2 put the Second Section card into the deck after its save check had run
and without a line in its notes. A deck one card larger shuffles differently from the same
seed, so every save on the test server refused at move 3 — the boot log shows thirteen of
thirteen — while the release notes said three would resume. `withSavedDeal` (was
`withSavedOpening`) now sets `secondSectionCard: false` for a config that predates the
setting, and the thirteen replay exactly as 0.8.2 described: three resume, ten refuse, the
same ten at the same moves.
THE RULES. `check` never tested that a switching tray was in the actor's own district, so
a rival's train could be shunted and the rival charged the Moves. Occupancy matched on
coordinates alone, so a rival's crew blocked your track. A Department draw that emptied the
deck duplicated the drawn card and destroyed the refill card. The unjam cleared the first
load rather than the one named. The collision floor could not fire in Stage 12. The
Expedite fault was charged once per clearance question rather than once per phase. A train
held at the Limits was only ever released by another arrival, never by a departure.
Docs: rules.md describes each as built (and no longer says an Expedited train departs at
Shift Change — that was v0.4.8's reading, corrected in v0.4.9's code and never in the
document); game-state.md's collision-floor note now matches the code.
