      'Bundles Station Master v0.8.2 — a playtest read back against its own save file. **The change you ' +
      'notice first: every district now opens on a DEPOT rather than a Whistle Post.** A Depot has two ' +
      'arrival/departure tracks and works passengers from the first Stage; a Whistle Post has one track ' +
      'and is not a passenger facility at all, so the opening of every game used to be spent unable to ' +
      'earn from a passenger and one arrival away from a wreck. A table that wants the harder game can ' +
      'tick "Players start with Whistle Posts, not Depots" when the game is created. **GAMES ALREADY ' +
      'RUNNING ON THIS SERVER: MOST WILL NOT RESUME.** Measured before release rather than discovered ' +
      'after: of the thirteen saved games on the test server, three resume and ten stop. Six of those ' +
      'ten are one new rule — a Waiting Area, Restaurant or Hotel may no longer be played at a Whistle ' +
      'Post, because a Whistle Post is not a passenger facility and the card did nothing there. A game ' +
      'that stops says which move it stopped on and its file is left untouched, so anything worth ' +
      'finishing can be finished by putting 0.8.1.0 back. **An Office could hold two trains on one ' +
      'track.** The train an Interlocking had been holding at the Limits took the track that freed, and ' +
      'the train arriving at that moment was let in after it without anyone checking there was still ' +
      'room — so the collision the rules call for simply did not happen. **Your history could freeze ' +
      'part-way through a game** and never gain another line, at a different moment for each player. ' +
      '**Trains were released when they should have been held**, twice over: a card that says "trains ' +
      'may pass" was clearing the whole line ahead rather than just itself, and a train standing at a ' +
      'full Office was invisible to the check although it was about to pull out again. **Things that ' +
      'happened silently now say so** — a train held against one coming the other way, a train released ' +
      'from the Limits, and the train an Interlocking is holding, which now draws differently on the ' +
      'board instead of only explaining itself in a tooltip. **When a move is refused, the board says ' +
      'which rule refused it.** **The documentation is a set of proper pages now**, served by this ' +
      'package and reachable from inside a game under This Game, instead of five files of plain text ' +
      'where every table came out as rows of pipes. **Smaller:** a Modifier must sit square against ' +
      'what it serves rather than on a diagonal; ordering a Second Section costs the card, which was ' +
      'declared in the rules and never actually dealt; a train may always recover its own caboose; and ' +
      'an industry may be built over a straight already laid.',

      'Incluye Station Master v0.8.2 — una partida de prueba revisada contra su propio archivo ' +
      'guardado. **El cambio que más se nota: cada distrito empieza ahora con un DEPÓSITO en vez de un ' +
      'Apeadero.** Un Depósito tiene dos vías de llegada/salida y trabaja viajeros desde la primera ' +
      'Etapa; un Apeadero tiene una vía y no es una instalación de viajeros, así que el comienzo de ' +
      'cada partida se pasaba sin poder ganar con un viajero y a una llegada de un choque. Una mesa que ' +
      'quiera el juego más difícil puede marcar "Los jugadores empiezan con Apeaderos, no Depósitos" al ' +
      'crear la partida. **LAS PARTIDAS EN CURSO EN ESTE SERVIDOR: LA MAYORÍA NO SE REANUDARÁN.** ' +
      'Medido antes de publicar, no descubierto después: de las trece partidas guardadas en el servidor ' +
      'de pruebas, tres se reanudan y diez se detienen. Seis de esas diez se deben a una regla nueva: ' +
      'una Sala de Espera, un Restaurante o un Hotel ya no pueden jugarse en un Apeadero, porque no es ' +
      'una instalación de viajeros y la carta no hacía nada allí. Una partida que se detiene indica en ' +
      'qué movimiento lo hizo y su archivo queda intacto, así que lo que merezca la pena terminar puede ' +
      'terminarse reinstalando 0.8.1.0. **Una Oficina podía albergar dos trenes en una sola vía.** El ' +
      'tren que el Enclavamiento retenía en los Límites ocupaba la vía que quedaba libre, y el que ' +
      'llegaba en ese momento entraba detrás sin que nadie comprobara que aún hubiera sitio, así que el ' +
      'choque que exigen las reglas simplemente no ocurría. **El historial podía congelarse a mitad de ' +
      'partida** y no añadir ni una línea más, en un momento distinto para cada jugador. **Se soltaban ' +
      'trenes que debían retenerse**, por dos motivos: una carta que dice "los trenes pueden cruzarse" ' +
      'despejaba toda la línea por delante en vez de solo a sí misma, y un tren parado en una Oficina ' +
      'llena era invisible para la comprobación aunque estuviera a punto de salir otra vez. **Lo que ' +
      'antes ocurría en silencio ahora se dice** — un tren retenido ante otro de frente, un tren ' +
      'liberado de los Límites, y el tren que retiene un Enclavamiento, que ahora se dibuja distinto en ' +
      'el tablero en lugar de explicarse solo al pasar el ratón. **Cuando se rechaza un movimiento, el ' +
      'tablero dice qué regla lo rechazó.** **La documentación son páginas de verdad**, servidas por ' +
      'este paquete y accesibles desde dentro de la partida en Esta Partida, en lugar de cinco archivos ' +
      'de texto plano donde cada tabla salía como filas de barras. **Menor:** un Modificador debe ir ' +
      'pegado en ortogonal a lo que sirve, no en diagonal; ordenar una Segunda Sección cuesta su carta, ' +

    /**
     * NOTHING TO CARRY, AND CHECKED THE SAME NARROW WAY v0.7.9.8's ENTRY WAS.
     *
     * The rule this package lives by is in the game's README: a save is a seed plus the moves
     * played, replayed through the CURRENT rules, so the only thing that strands an older save is a
     * change that makes a once-legal move illegal. So the question is never "how big was the
     * release" — v0.8.0 is a large one — but "did any predicate change its answer".
     *
     * Measured with `git diff v0.7.9.8..v0.8.0.1 -- src/engine/`. The WHOLE engine diff is eight
     * lines:
     * four `GameEvent` types (`trayMoved`, `carsCoupled`, `carsDropped`, `consistSorted`) gained a
     * `player` field, and the four places that build them pass it. `check()` is untouched, `legal.ts`
     * and `advance.ts` are untouched, and no predicate anywhere was edited. Games in progress resume,
     * and the release notes say so in all five locales rather than leaving it to be discovered.
     *
     * EVENTS ARE NOT PERSISTED, so widening four of them cannot invalidate anything on disk: a
     * `SavedGame` is `{ seed, config, history: Intent[], … }` and the events are derived by replaying
     * it. The narration TEXT of two lines changed with them ("Moved Train 3 …" where it used to read
     * "CREW moved …"), which a resumed game simply regenerates — the log is not stored either.
     *
     * WHAT IS NOT COVERED BY THAT ARGUMENT, and why it still does not need a migration: the wire
     * between this server and a browser gained a lot. `Push` now carries ordered presentation steps
     * and a public-board baseline, and the board deltas changed shape. None of it is on disk, and a
     * browser reloads onto the new page as part of the update, so there is no version skew to
     * migrate — the same reasoning v0.7.9.8 used for its own `Frame` changes.
     *
     * v0.8.0.1 ADDED NOTHING TO THIS ARGUMENT: `git diff v0.8.0..v0.8.0.1 -- src/engine/` is empty.
     * It changed `sim/pacing.ts`, `web/step-queue.ts` and `web/main.ts` — how long a step is shown
     * and when the queue calls itself idle — which is presentation and touches neither the rules nor
     * anything on disk.
     *
     * v0.8.0.2 DOES TOUCH THE ENGINE, and it is worth being exact about why that is still nothing to
     * migrate. `git diff v0.8.0.1..v0.8.0.2 -- src/engine/` is three added lines: `collisionsPrevDay`
     * declared on `GameState`, initialised to 0 in `setup.ts`, and assigned at the Day rollover in
     * `advance.ts`. It is a counter that nothing checks — no predicate reads it, so no once-legal move
     * became illegal.
     *
     * v0.8.0.3 THROUGH v0.8.0.7 ADDED NOTHING: `git diff v0.8.0.2..v0.8.0.7 -- src/engine/` is empty.
     * One moved the Skip button, changed what the waiting row says, and stopped the speed control
     * stretching the clock; one took a hostname out of comments; the last drew the Home Office deck
     * and lit the pile a watched move touched, which is a diff of two frames the client already
     * holds. None of it is a rule, and none of it is on disk.
     *
     * v0.8.0.8 IS DIFFERENT AND IS THE ONE TO READ CAREFULLY: it changes a RULE (Gitea#23). When the
     * Home Office deck is reshuffled, a timetabled train sitting in the SALVAGE YARD is no longer
     * recovered — it was played, its number is on the timetable, and it cannot be run twice. The same
     * card in a DEPARTMENT was discarded rather than played and still comes back, as does any Extra.
     * A duplicate went with it: `trainScheduled` had been pushing a synthetic `train-<n>` beside the
     * real card, so four scheduled trains left eight entries in a pile of four.
     *
     * GAMES IN PROGRESS STILL RESUME, and the reason is the narrow one this package always asks
     * (README § Design notes): a save is a seed plus the moves played, replayed through the CURRENT
     * rules, so what strands one is a change that makes a once-legal move ILLEGAL. Nothing here does.
     * `check()` is untouched; a draw is a draw whatever lies on top of the deck. What differs is the
     * Salvage Yard's depth, which was double-counting, and which cards a reshuffle returns — and a
     * reshuffle is effectively unreachable in ordinary play: eight games driven to 4000 moves across
     * eight seeds produced ZERO. A game that had somehow reshuffled would replay to a different deck
     * order rather than refusing to replay, which is worth knowing and is not the same as breaking.
     *
     * v0.8.0.9 TOUCHES THE ENGINE FOR SPEED, AND PROVED IT CHANGED NOTHING. `git diff v0.8.0.8..v0.8.0.9
     * -- src/engine/` adds a route cache scoped to one unchanged position (`withRouteCache`), splits
     * `applyIntent` into `prepareIntent` + `commitEvents`, trims allocation in `exploreMoves`, adds
     * `legalSwitchingActions`, and exports `badlyMadeUp`, `protoCard` and `extendLimitsIfNeeded` for the
     * bot. No predicate's answer changed: every event and intent of 32 seeded games hashed identical before
     * and after each step, and the game's `test/route-cache.test.ts` pins the split. Everything else is the
     * developer bot, whose past moves are already intents in a save. Games in progress resume.
     *
     * v0.8.0.10 IS THE FIRST BUMP THAT BREAKS RESUMES, AND IT DOES SO DELIBERATELY. It corrects WHEN §8.1
     * asks the Superintendent to rule (Gitea#26): a train on a card BEHIND the one departing is nobody's
     * concern, and was being counted. A save is the seed and the moves replayed through the CURRENT rules,
     * so a game holding a `mainline.clearance` the rules no longer ask for is refused at that move with
     * NO_PENDING_DECISION — `tryResumeSession` reports which move, and `index.ts` logs the refusal and
     * leaves the file alone. Measured before shipping: 40 four-seat co-op games recorded by bots under
     * v0.8.0.9 and replayed under this release — 28 stop, usually 5-40% of the way in. Jesse's call
     * (2026-09-15): no games in progress need keeping, so this ships without a per-game switch for the old
     * rule, and the release notes say so in all five locales. A game worth finishing can be finished by
     * putting v0.8.0.9 back — the save file is untouched.
     *
     * The rest of the release is the screen and the log — who the board says it is waiting on, what the
     * history says and when it says it, a flash on a realigned Mainline card — plus one new read-only
     * route (`GET /api/save?token=…`) that hands a seated player their own save. None of it is on disk.
     *
     * A NEW STATE FIELD CANNOT STRAND A SAVE HERE, which is the property worth naming rather than
     * re-deriving: a `SavedGame` holds `{ seed, config, history }` and NOT a serialised `GameState`.
     * Resuming calls `createGame` — which fills the new field from `setup.ts` — and then replays the
     * intents through the current rules, so the field is populated on the way past. There is no old
     * shape on disk for a new field to be missing from.
     *
     * THE ONE THING THAT WOULD HAVE NEEDED CARE, had it been built the way the plan first described:
     * the display-step collector runs inside `submit()`, and the resume path (`fromMultiplayerSave`)
     * deliberately does not go through `submit()`. So replaying a saved game emits no steps and burns
     * no sequence numbers. A test in the game pins that, because it is a property rather than an
     * accident.
     *
     * v0.8.0.11 RESUMES, AND IT WAS MEASURED THE SAME NARROW WAY — which matters more than usual
     * here, because the release immediately before it is the one that did NOT.
     * `git diff v0.8.0.10..v0.8.0.11 -- src/engine/` is three files and nineteen insertions:
     * `trainArrived` gains an `owner` field (`events.ts`), the one line in `advance.ts` that fills
     * it from `playerAtSeat`, and a Mainline card's printed description losing a sentence about a
     * speed that is not drawn on the card (`content.ts`). `check()` and `legal.ts` are untouched and
     * no predicate was edited, so nothing once legal became illegal. Events are not persisted — a
     * `SavedGame` is `{ seed, config, history }` and the events are derived by replaying it — so
     * widening one of them cannot invalidate anything on disk, exactly as the v0.8.0.1 entry above
     * argues for four of them.
     *
     * THE REST OF THE RELEASE IS THE SCREEN: a Pause control for the catch-up queue, a one-render
     * look at another player's Office Area, the turn chart following the step being replayed rather
     * than the live game, "still needs" on the make-up panel, the amber on an addable yard chip, and
     * save filenames carrying the join code. None of it is a rule and none of it is on disk.
     *
     * v0.8.0.12 TOUCHES THE ENGINE NOT AT ALL, which is the shortest entry this comment has ever
     * had a right to: `git diff v0.8.0.11..v0.8.0.12 -- src/engine/` is EMPTY. The release is the
     * server's HTTP surface, the browser client and the docs — a seat recovery flow (Gitea#33) for
     * a player whose browser has lost the token that is their only identity.
     *
     * WHAT IT ADDS, AND WHY NONE OF IT IS A MIGRATION: two routes (`POST /api/games/<id>/claim`
     * behind the admin secret, `POST /api/claim` for the player following the link), a `?claim=`
     * entry path in the client, and `seatedPlayers` on the administrative game listing. The codes
     * themselves live in memory and are deliberately NOT persisted — minted on demand and spent
     * within minutes, so a restart dropping them is the right failure rather than a loss. Nothing
     * new is written to the volume, no predicate was edited, and `check()` and `legal.ts` are
     * untouched, so no once-legal move became illegal. Games in progress resume, and the release
     * notes say so in all five locales.
     *
     * v0.8.0.13 TOUCHES THE ENGINE AGAIN, AND THE WHOLE DIFF IS TWO LINES.
     * `git diff v0.8.0.12..v0.8.0.13 -- src/engine/` adds a `superintendentChanged` variant to the
     * `GameEvent` union (`events.ts`) and the one `events.push` in `advance.ts` that emits it beside
     * the `actorChanged` that was already there — §5's handover of the Fedora, which the log had been
     * dropping as turn bookkeeping. Nothing was removed and nothing was edited: `check()`, `legal.ts`
     * and every predicate are untouched, so no once-legal move became illegal, and a widened event
     * cannot invalidate anything on disk because events are DERIVED by replaying a `SavedGame` rather
     * than stored in one — the same argument the v0.8.0.1 and v0.8.0.11 entries above make for
     * theirs. Games in progress resume, and the release notes say so in all five locales.
     *
     * THE REST IS THE SCREEN AND THE LOG, none of it on disk: the Division Yard chips now obey the
     * catch-up queue (they did not, and a click during it submitted a real intent against a stale
     * board), the yard counts are read from the shown board rather than the live game, the district
     * picker gained your own seat and is ordered by seat rather than by player index, collisions name
     * the district's owner and the 5 Revenue they lose, a Depot that cannot stock an outbound
     * passenger explains which car it is short of, and the history panel keeps 90 lines. The
     * passenger case is a RULING rather than a fix — §6.3 wants a loaded coach in the Division Yard,
     * and Jesse kept the shortage (Gitea#2's ruling) while ending the silence about it.
     *
     * v0.8.0.14 IS THE SECOND BUMP THAT BREAKS RESUMES, AND LIKE v0.8.0.10 IT DOES SO DELIBERATELY.
     * A Modifier card may no longer be placed outside a player's Limits (§2.1). That REVERSES an
     * earlier ruling of Jesse's — Modifiers were exempt because a Facility standing at the limit has
     * three of its nine spots beyond the sign — and it is exactly the shape of change this package's
     * `UPDATING.md` says to look for: a predicate in `apply.ts` changed its answer, so a move that
     * was legal when it was played is refused on replay.
     *
     * MEASURED, NOT ESTIMATED. The Day 3 playtest save stops at intent 528 of 539 —
     * `card.play c55 → (-2,4)` with the sign at column 3 — eleven moves short of where the table had
     * got to. `tryResumeSession` names the move, `index.ts` logs the refusal, and the file is left
     * untouched, so re-installing v0.8.0.13 finishes any game worth finishing. Jesse's call, knowing
     * it strands the game that was on the box.
     *
     * THE REST OF THE ENGINE DIFF STRANDS NOTHING, and is worth separating from the part that does.
     * `makeUpShort` is a new event reporting that the make-up round could give a train nothing;
     * `switchingEnded` closes a switching turn; `trayMoved` carries the Stage's Move allowance and
     * `consistSorted` carries where the engine ended up; `switch.sortConsist` gained an OPTIONAL
     * `engineAt` (absent means the nose, which is what every sort did before, so an older save
     * replays to the same train). Events are derived by replaying a save rather than stored in one,
     * and an optional intent field defaulting to the old behaviour changes no past move.
     *
     * THE SMALL YARD RULE CHANGED IN THE PERMISSIVE DIRECTION, which cannot strand a save either: a
     * train there may now be sorted with cars ahead of its engine (`implications.md` against the
     * v0.4.5 card text, Jesse's ruling). Nothing once legal became illegal; §8.2's departure check is
     * untouched and still holds a broken-backed train at the Office.
     *
     * v0.8.0.15 AND v0.8.0.16 CHANGE NO RULE AND STRAND NOTHING.
     * `git diff v0.8.0.14..v0.8.0.16 -- src/engine/` is one sentence of card TEXT and one doc
     * comment. The Interchange stopped telling players "Cars may be sorted into any new order here"
     * — a printed capability that has never been implemented, reaching the board through
     * `mainlineDescription`, which `view.ts` renders as a Mainline card's `what`. Nothing reads
     * `sortsCars` to permit a sort; its only live use is marking the card an Extra may be made up
     * on. No predicate was touched, so no once-legal move became illegal.
     *
     * The rest of those two releases is documentation inside the repository — a Quickstart for a new
     * player, and the four hand-written references brought up to the game as it runs. None of it is
     * served by the site or read by the service; it rides along in the image because the Dockerfile
     * copies the game's tree in.
     *
     * SO THE RESUME WARNING IN THESE RELEASE NOTES IS ENTIRELY v0.8.0.14's, and it still applies:
     * a box on 0.8.0.13:0 takes this update in one hop and meets the Modifier rule on the way.
