v0.8.5 — housekeeping from the audit, and the playtest line retired
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 The 0.4.9 playtest line is no longer maintained (Jesse, 2026-09-29): the deploy rule that existed for it is gone and #85 is moot.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.

v0.8.3 — the engine half of the audit, and the deal 0.8.2 silently changed
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.

v0.8.2 — every district opens on a Depot, and the docs are pages now
A second-digit bump for a playtest read back against the save file. Nine questions were asked of one three-Day game; three were bugs, three were the rules working and undocumented, three were decisions. Every save on the test server was replayed against this build BEFORE release, which is how the cost of each rule was known before it was chosen rather than discovered after. EVERY DISTRICT OPENS ON A DEPOT. A Whistle Post has one A/D track and is not a Passenger Facility, so the opening of every game was spent unable to work a passenger and one arrival away from a collision. Two A/D tracks and passengers from Stage 1 now; "Players start with Whistle Posts, not Depots" is the harder game, set when the game is created. The deck follows the choice — starting on Depots the four Depot upgrade cards are left out, because an upgrade must be to the next tier and a Depot card at a table of Depots is a dead draw. How much easier it is showed up as a test failure rather than an argument: the cue-coverage pool needed widening from 24 seeded games to 60 before it held one collision. NO SAVE WAS STRANDED BY IT, which took care. This is the one house rule that changes how a game is DEALT rather than how it plays, so replaying a save under the wrong opening is a different railroad from intent one — silently, with no error. `withSavedOpening` fills it on the replay paths ONLY. Putting it in the resolver instead made a fresh Cutthroat game deal Whistle Posts and read as Custom, which is how the distinction was found. THREE BUGS, ALL REPORTED FROM ONE GAME AND ALL CONFIRMED ON ITS SAVE. An Office held TWO TRAINS ON ONE A/D TRACK. The capacity test passed with nothing standing, the train the Interlocking had been holding at the Limits was moved into the free slot, and the arriving train was pushed in after it without anyone asking again whether there was room — so the collision §8.3 calls for never happened. The held train keeps priority; the newcomer now takes the consequence it would have met had the held train arrived first. THE HISTORY FROZE, permanently, and the log cap was not really the cause. Each seat's "what have I sent you" bookmark was an INDEX into an array the game trims, so once a seat's bookmark reached the limit the slice returned nothing for the rest of the game — at a different moment per seat, because each holds its own. That game's log ended at exactly the cap. Lines carry a sequence number now, which survives trimming; proven by pushing twice the cap through a simulated seat. §8.1 ASKED THE WRONG QUESTION TWICE. "Trains may pass" returned `clear` before the Subdivision was looked at, so a train entering a Double Track was released however busy the rest of it was — that, not anything about Control Points, is what let Train 8 out with no ruling. And a train standing at an Office was invisible to the scan, so one about to re-enter the very Subdivision being entered counted for nothing. Capacity is the test, not presence: a Depot with a track free is not in the way; a Whistle Post with its one track taken is. THINGS THAT HAPPENED SILENTLY NOW SAY SO — a train held against a facing one, a train released from the Limits (a side effect of somebody else's arrival, so it simply appeared at the Office), and the train an Interlocking is holding, whose explanatory tooltip has existed since #99 with NO renderer ever reading the flag. WHERE A MOVE IS REFUSED, AND WHY. `exploreMoves` decides where the rails go and the pick-up restrictions are enforced afterwards in `check`, so a square the rails reached and the card forbade was reachable, un-offered, and absent from the block list with nothing said. Those squares are blocked with the rule that blocks them now, and the reasons are got by ASKING `check` rather than re-deriving: a second implementation of the rules is exactly the failure the block list exists to avoid. A train may also always recover its own caboose — X13 prints "may drop but not pick up anything", and a train needs its caboose to be made up, so one that parted with it could never legally leave again. RULES DECIDED IN SEPTEMBER AND APPLIED HERE. A Modifier must sit square against its host, no diagonals. A passenger Modifier may not be played at a Whistle Post. Both were built, measured, held back for a fortnight so a playtest could finish, and applied now. A Second Section costs its card: `SECOND_SECTION` was declared in content.ts and never dealt, so the action was free and the bot ordered 26 accidental ones in a measured round. The card is dealt and spent — gating on a card the deck never holds would have deleted the mechanic rather than fixed it. THE DOCUMENTATION IS A SET OF PAGES, not five text files served as text/plain — a card reference is mostly tables, and as plain text a table is rows of pipes. Markdown is still the one copy; the build renders it, and publishes the .md beside each page. No Markdown library: this project has no runtime dependencies and one would be a poor first. The pages add what Markdown cannot carry without drifting — a nav across the set, a contents list built from the headings actually rendered, an anchor on every heading, a 70-character measure, and tables that are tables. They print as ink on paper. The references caught up with the rules, checked rather than assumed: two statements had gone from stale to misleading (the Quickstart told a new player to "get a Depot down as soon as one appears"), and four rules nobody could look up are written down — the Office tier table, §8.1 in practice, what the Circus Train pays for, and that a Realignment can be a card with no legal target. Adding one card to the deck reshuffles every seeded deal, which broke five fixtures. Each was a seed meaning "a game like this" — TODO #84, exactly — so seeds moved and pools widened rather than assertions weakening, and the clearance fixture pins its terrain the way `enhancements.test.ts` already does. The three published replays were re-recorded. Closes TODO #40, #42a, #108, #109 and #110. 1046 fast tests and 35 sim tests pass.

v0.8.1.0 — the car comes back empty, and the lobby lets you leave
A second-digit bump, deliberately. 0.8.1 had been reserved for the seatless display table; that work is getting more thought, and this table pass over v0.8.0.17 earned the number on its own. Six reports: one was a rules question, one a wording complaint with a real bug underneath, four straightforward. A CAR CLEARED FROM A RED INBOUND BOX CAME BACK STILL LOADED. Reported as wording — "technically accurate but doesn't make any sense" — and the wording was the visible half. `inboundCleared` pushed `pooled(e.stock)` under a comment reading "a car back in a yard is back in the common supply, carrying nothing", and `pooled` does not do that: it strips the load's origin stamp and keeps `loaded` ON PURPOSE, because a train can retire at a Division Point with freight aboard. So the comment described an intention the call never carried out, and every car the Freight Agent cleared reached the Classification Yard carrying a load already delivered and already paid for. It bites hardest on coaches: `passengersDetrained` takes `coach && !loaded` out of the Division Yard and §2.2 refills that yard from Classification, so a cleared coach came back as stock that could never unload another passenger. Measured over five three-Day solitaire games: 18 loaded coaches in Classification against 6 empty. The red box is where a journey ENDS; clearing it sends the passengers out of the station, or the delivered load into the industry, and returns the CAR, empty. The option says that now instead of describing the counter that moves. SCOPED TO THE RED BOX ON PURPOSE. `retireTrain` also returns loaded cars and is left alone: that is what `pooled`'s own documentation describes, and a loaded car in a yard is pre-loaded cargo rather than dead stock — it can be made up and delivered, and a loaded coach can still detrain. Only the red box's contents had already finished their journey. GAMES IN PROGRESS DO RESUME, MEASURED RATHER THAN ARGUED. Yard contents change, so the worry was real. All twelve saves on the test server were pulled and replayed through `tryResumeSession` — the server's own boot check — against this build. Six resume, six refuse, and the six refusals are the SAME six, at the same moves, with the same codes, that 0.8.0.17 already logged. Nothing new was stranded. That pre-install replay is a better check than reading the next boot log, because it answers before the install rather than after. THE HISTORY SAID "Mainline card 7" and left the reader to remember what card 7 was — with two Plains dealt, which is why the slot is kept beside the name rather than replaced by it. A second fault sat one word to its left and nobody reported it: the name was built as `e.key.replace(/([A-Z])/g, ' $1')`, so `absSignals` printed as "abs Signals" while the action list directly above said "ABS Signals". `narrate` takes `mainlineAt` and `enhancementName` beside the `facilityAt` it already had, and `simpleCardName` is exported so the log reads the same table the buttons do. `mainlineModified` had both faults and is fixed with it. LEAVING A RUNNING GAME WAS A DEAD END. `enterSeating` hides the choice section and only the lobby's own two leave paths put it back; leaving a running game is a third route, so the lobby came back holding nothing but "Games you are in" with both doors on the page at display:none and no control able to reveal them. Reset in `runLobby`, which is the one function every route onto that screen goes through — which is exactly why the two paths that did it themselves missed a third. THE LOBBY'S ACTION BUTTONS CARRY THE BOARD'S AMBER. A list of the actions rather than `#lobby button`: the settings form under Create is a field of inputs, and amber on all of it would say everything is a move and so say nothing. A disabled Start game drops back to chrome. THE DEPARTMENT REFILL IS A RULE AND IS NOW WRITTEN DOWN. §6.2 — "if any of the Department decks is empty, draw a Home Office card and place it in the empty spot" — firing only when the draw actually empties the pile. Kept as implemented (Jesse's ruling) and stated in rules.md and home-deck.md, neither of which had ever mentioned it. A rule implemented from the prototype and never written down is a rule that surprises the table. 1016 fast tests and 35 sim tests pass.

v0.8.0.14 — the coaches that never come back, and a district that ends at its own sign
Six reports from the Day 2-3 playtest of v0.8.0.13. GAMES IN PROGRESS DO NOT SURVIVE THIS ONE. Modifiers are now bounded by the Limits, which makes a once-legal move illegal, so a save holding one is refused at that move: whistle-6945.day3.stage10 stops at intent 528 of 539. Jesse's call, knowing it strands the game on the box. The file is untouched and v0.8.0.13 still finishes it. The Sparrow running empty and Tom unable to unload his passengers are the same shortage from opposite ends, and both are the rules working as printed. §9.2 boarding discards the emptied coach into the CLASSIFICATION yard, detraining draws a fresh empty out of the DIVISION yard, and §2.2 sends Classification back only when the Division Yard runs bare — so coaches move one way. Measured over the save: sixteen in the Division Yard at setup, zero from Day 2 Stage 8 to the end, fifteen piled in Classification, the Division Yard steady at 46-47 freight cars with no prospect of going bare. Jesse's ruling is Gitea#2's: the shortage stays and the game says so. A train made up short now reports what its card wanted and why none is coming (`makeUpShort` — `trainNeedingCars` answered null for "done" and for "cannot be done" alike, so the phase moved on in silence); the yard panel warns while the condition lasts; the Depot's blocked panel was right all along. The modifier outside the Limits was working as designed and the design was Jesse's own call, now reversed. What decided it is what the board shows — a card beyond your own sign, in territory §8.1 and §10 reason about. The case that motivated the exemption was checked on the reported move rather than argued away: the Power Plant sat at (-1,3) against a sign at column 3 and two spots inside were free, legal and adjacent. Switching filled the history with coordinates — a line per move, plus one per mandatory coupling. It is still LOGGED in full; what the panel draws is the line saying somebody switched, the first move, work at an INDUSTRY (named, not a coordinate), the Small Yard sort, and a closing summary. The suppressed lines are still WRITTEN, marked `trace`: dropping them outright was the first attempt and the step-queue suite caught it, because dwellForStep pays nothing for a step that said nothing, so the board stopped replaying switching at all. The last move rides in the closing line rather than being kept in place — nothing knows a move was the last until the turn is over, by which time the line has been streamed to every client and cannot be revised. Two things fell out of reading those lines: every move ended with a tutorial sentence the opener already gives, and the move count said "of 6" with the six hardcoded, which is wrong on a night Stage. Make-up lines name their train — they all read "the train being made up", so looking back for train 10 found nothing under that name — and "a empty tank" is now "an empty tank". The Small Yard's options read as the train they would build instead of `[1,2,3,0]`; the one Jesse wanted was the first of five and unreadable. Two of those five were junk: bringing the last car to the end is the identity and would have spent a Move, and a two-car reversal duplicated its only real option. Both are filtered by the resulting order, not by the case that made them. A Small Yard may now put cars AHEAD of the engine, which was Jesse's own open question. Two sources disagreed and the design notes won: the v0.4.5 card text says the sort puts the engine at the nose, implications.md says "any order, including cars ahead of the engine". `engineAt` is optional on the intent, so older saves replay to the same train. The menu did not multiply — the engine is a separate short list against the consist as it stands, eight options for a four-car train rather than twenty. §8.2 needed no new code: badlyMadeUp is deliberately direction-free, so a PUSHING train is fit to run and only a broken-backed one is held. The button warns by asking that predicate rather than copying it, and immediately earned itself — every one of train 10's eight options is refused, the one asked for at the table included, because that train carries a caboose and each sort moves it off the rear. That is the right answer rather than a gap: the train is already made up, so every offer would break it, and the labels say which is which. A made-up order is always on the menu for a train that needs one, because "bring car k to the tail" is enumerated for every car and the caboose is one of them. Labels read WEST TO EAST, with the engine drawn as the board's own ◀ / ▶ arrow. "Front to back" is not a direction a table can read — which end is the front depends on which way the train points — and board-svg has reversed east-facing consists since v0.8.0, so the button now describes the same train as the picture. The Freight Agent, Porter and Laborer groups now say what the role is for, where the role is chosen. Tom reached for the Freight Agent to detrain passengers, which is a Porter's action in the Cargo phase; both halves were working and neither was visible. TODO closes #107 (the nose sort) and gains #108 (the coach ratchet, with the measurement, to revisit on a second game's data). 999 fast tests and 35 sim tests pass.

v0.8.0.8 — a played train does not come back; a discarded one does
Jesse's ruling on the question v0.8.0.7 filed: once a regularly scheduled train has been played its number is on the timetable, so putting it back into a reshuffled deck to be played again makes no sense. The same card sitting in a discard pile was never played and its slot is still open, so it should come back. An Extra is a single run rather than a standing slot, so a played one is free to run again. The test is therefore WHERE the card is, not only what it is — which is worth writing down, because it is exactly the rule a later tidy-up would simplify into filtering by kind everywhere. And the duplicate that started it: trainScheduled was pushing a synthetic train-<number> into the Salvage Yard beside the real card cardPlayed had already put there — four scheduled trains left eight entries in a pile holding four cards. Nothing read it, it inflated the depth, it displayed as "a card", and it would have been swept into the draw deck to be drawn as an id with nothing behind it. Removed, which retires the phantom-id class rather than papering over it, so v0.8.0.7's cardName resolver for it goes too. Games in progress resume: no predicate changed its answer, and a draw is a draw whatever is on top. What differs is the Yard's depth, which was double-counting, and what a reshuffle recovers — and reshuffles are effectively unreachable, with zero seen across eight games driven to 4000 moves. Closes #23. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01X6cF1iYvJ1kNmzYBzu4QX6 |

v0.8.0 — the board replays what everyone else did, instead of arriving rearranged
TODO #13, #15 and #18 — Gitea#20 steps 2-4 pointed at a seated player's own screen. Every accepted intent, and every automatic phase that does anything, becomes an ordered presentation step. A bot's whole switching turn used to land in one push; now it arrives as a run of steps, the district panel follows whoever is acting, and a [N behind] … [Skip] row says how far the board is from the game. Solitaire runs the same path — one collector inside submit(), which both session kinds already funnel through — which is where its automatic phases finally get a visible beat. Dwell is assigned by kind: switching holds the screen, turn bookkeeping costs nothing, and the clock turning over earns the beat. Tunable per viewer without a rebuild, and off entirely at pace 0. Also: switching was the one class of action logging unattributed, and now names its train. Reasoning, measurements and the three things that turned out wrong are in CHANGELOG.md.

The Yard Office is offered, reachable, and can be run into (Gitea#5)
"Trains that are only freight (cabooses ok, no coaches allowed) that arrive in a
player's area who has the yard office card get an extra ability… the game will
offer that player the option… They can of course still choose to have the train go
to the standard office."
It was implemented, in a stripped form missing all three conditions: a qualifying
train was TELEPORTED onto the Yard Office card. Nobody was asked, no route was
computed — so the card's own printed "that can reach the yard office in one move"
was unenforced — and because nothing was walked, nothing was ever met on the way.
All three now hold:
- OFFERED to whoever sits in the district, interrupting the Mainline Phase on the
turn the train arrives. Declining is an ordinary arrival onto an A/D track.
- REACHABILITY is the engine's own move walk. `exploreMoves` already means what
the card means — any distance without changing direction, finishing on
Operational Rail (§2.4, §A.1) — so using it is what makes code and card agree.
Reversing is a separate Move, so a yard that can only be reached by backing up
is correctly out of reach.
- CARS ON THE LEAD COLLIDE. The walk does not treat standing cars as obstacles;
it COUPLES them, because that is what a switching move does. An arriving train
is not switching, so what it would have coupled is what it is about to hit —
the same reading §8.3 already applies to the Running Track. `destination.couples`
is therefore the fouling signal, and it needed no new machinery.
Per Jesse's ruling (2026-08-29) the two failures his issue names are kept apart: no
route means no offer, with the history saying why ("make sure this is logged in
history — why can't move so user knows why they can't get to yard"); a route that
exists but is fouled IS offered, and taking it crashes. A silent absence is
indistinguishable from a broken feature, which is how the missing check survived.
THE SHARED REFACTOR THIS NEEDED. `pendingDecision` was one question asked of one
player — §8.1's clearance, always the Superintendent — and `currentActor` hardcoded
that. It is a discriminated union now, with `decisionActor` as the single place that
maps a question to whoever must answer it, and `clearanceRuling` generalised to
`decisionAnswer`. Six copies of `pendingDecision !== null ? superintendent :
currentActor` across the engine, the sim, the web client and the tests collapse into
`actingPlayer`; they had already stopped being right the moment a second kind of
question existed. Gitea#19 needs the same machinery and now only has to add a case.
A BUG THE FIRST CUT WALKED INTO, worth recording because it is a trap the next
interruption will meet too: the offer must be put BEFORE the train is taken off its
Mainline card. `needsClearance` unwinds the whole phase and the driver re-enters
from the top, so asking after the `transits` filter cost the train its place on the
card and the answer had nowhere to land. §8.1 gets this right by asking before it
commits, and the Yard Office now does the same.
The developer bot declines: the Yard Office frees an A/D track, but the lead may be
fouled and the bot cannot read its own yard well enough to tell (`TODO.md`, Bot
Performance). Declining is always safe and keeps the harness comparable with every
measurement taken before this rule existed.
851 tests pass.
Closes #5

v0.7.1 — a caboose is not a load, a Day that says it ended, and a train you may throw away
Four issues off the Gitea tracker, all of them things a player saw at the board. Reasoning for every item, and what was verified how: CHANGELOG.md. - Gitea#8: X22 Pee-Dee refused every caboose, including the one it was made up with, so setting it out stranded the train. All six cabooses are minted loaded because §2.2's "coloured is loaded, white is empty" doubles as a piece count in the supply table; one read of the flag took that literally. A caboose carries the crew, not freight, so it is never a load. - Gitea#10: a Day turns over inside the phases that run themselves, so it passes between one click and the next — and both transient signals fade before a player reading the board notices. A modal stops and waits, carrying the standings, the Days left and the combined target. Suppressed on the first frame, on Undo stepping back across a rollover, and on the Day the game ends. - Gitea#9, which SUPERSEDES Gitea#6 from three days ago: a Timetabled train may be tossed face-up to a Department slot, where a rival may pick it up — the second half of the ruling needed no code, since that is where every discard already goes. An Extra still may not. A New Game setting on this line (discardTimetabled, on by default), the plain rule on the 0.4.9 line. - Gitea#2 is not an engine bug: the rules are implemented exactly, and running the coach pool dry is Jesse's ruling to keep — "part of the strategy". What was wrong is that the game said nothing. A blocked platform now gives its reason, from the engine's own predicate, including how many coaches are stranded in Classification and what brings them back. The same four ship as v0.4.9g on the playtest line.

v0.6.2 — an Extra starts where you put it, a train card is never discarded
Three more from the v0.4.9e gameplay-testing round, filed as Gitea issues, plus two bugs found underneath them. Gitea#2 is diagnosed but NOT fixed: it needs a ruling, and the reasoning is in TODO.md under Play Balance. GITEA#4 — AN EXTRA STARTS WHERE THE PLAYER PUTS IT. Only one Division Point was ever offered, chosen by number parity. The number no longer decides an Extra's direction — the start does, which supersedes the recorded ruling that "the number decides, like everything else on the timetable". The two cannot both hold: an odd, westbound Extra placed at the WEST end would leave the Division on its first move having crossed nothing, and be paid for the run. Either end now runs the train away from itself; at an Interchange or a Control Point the player picks the direction. The Interchange start is a YARD, off the running line, which is what makes the Superintendent clause work: placing it can never force a collision, a guaranteed one holds it there for another Stage, and a potential one is the Superintendent's to rule on — exactly evaluateClearance's `blocked` and `ask`, so nothing new decides collisions. Where an Extra may start is now a house rule (divisionPointsOnly / ownOffice / anyOffice, defaulting to what the engine already did). The legacy `atSeat` intent field still replays as it always meant. FOUND UNDERNEATH IT: an Extra started away from a Division Point ran empty. isBeingMadeUp tested position alone, so the Control Point start has been shipping since it was added with a train that could never be given a consist. Found by playing it, not by the tests, which had only asserted where the tray landed. FOUND UNDERNEATH IT: collide left the wrecks on the card. Destroyed trains kept their Transit entries, and evaluateClearance counts every transit as an occupant, so one rear-end collision permanently poisoned that Mainline card for every later train. THE MAINLINE CARDS WERE ROLLED, NOT DEALT — drawn from the nine types with replacement, so a Division could hold two Interchanges and Plains carried the weight of a card printed once. "An Extra may start at the Interchange if one is on the board" only reads as a rule if the board holds at most one. Now dealt from the printed deck without replacement, verified over 1600 deals. This re-deals every seed: the published replays were re-recorded, and the saved games in docs/ are retired too — two of those were already dead before this release and nobody had noticed. GITEA#6 — A TRAIN CARD IS NEVER DISCARDED, Timetabled and Extra alike. The forced play needed no mechanism: nothing discardable plus a hand over the limit leaves exactly one legal way to end the turn, and playing a train is unconditionally legal, so the corner cannot trap anyone. The bot needed no rule either. 400/400 games finished, revenue unmoved, trains scheduled 1.2 -> 1.3. The player is told on the card and on the button. GITEA#7 — COACH COUNTS. 1/2 Crack Limited 3 -> 2, 5/6 The Sparrow 2 -> 3. A change to the cards, so Trains3.pdf and the transcription keep the original numbers with a footnote while content.ts and the Home Deck reference carry what the game plays. CONTENT.TS COMMENT PASS — no data changed, only comments. Four were factually wrong, including an office table naming counts doubled long ago and a pointer to a DEALT_DECK_SIZE that has never existed. Every Enhancement row cited its implementation by line number and every citation had rotted; they name functions now. Card counts came out of the comments, since they move with play balance; source-sheet figures and dated measurements stayed. TODO.md gains an item for a card reference generated from content.ts, in six sections, so the documentation cannot disagree with the game. 715 tests pass, tsc clean, site builds. |

v0.6.1 — five of six playtest bugs: one button per train, and a load that has to go somewhere
Gameplay testing on 0.4.9d returned six reports. Five are fixed; the sixth could not be reproduced and is written up in TODO.md with the two questions that would pin it down. TWO TRAINS AT ONE PLATFORM ANSWERED TO ONE BUTTON. `porter.board` and `porter.detrain` carried no tray, so there was one button per platform however many trains stood at it and the reducer filled the first empty coach on the A/D tracks. `check` and the reducer were not even asking the same question: `check` skipped a train whose card refuses passenger work and the reducer did not. Both intents now carry an optional `trayId`, one function resolves the train and the coach for check/execute/reduce alike, `legal.ts` offers one candidate per train, and the label names it. A LOAD COULD BE MADE AND BROKEN WITHOUT GOING ANYWHERE. A Freight House could unload the boxcar it had just loaded; a platform could detrain the passengers it had just boarded. Full Revenue at both ends for a movement that never happened. Jesse's rule: a load made anywhere in an Office Area may not be broken anywhere in that Office Area, ever — it has to be carried to another district. The load carries the seat that made it (`RollingStock.origin`), stripped by `pooled` at every yard push. Measured at -0.60 +/- 0.10 Revenue a game (t = -6.1) over 400 paired deals: 78 worse, 3 better, 319 unchanged — free Revenue coming off the board, not a nerf. THE GROCER'S WAREHOUSE SHIPPED AND THE REFINERY RECEIVED. Both were `flow: 'both'` on the reading that "Freight House" was a collective term for exactly those two, and therefore what §9.3 described. The engine has dealt a Freight House CARD since before v0.4.9, so §9.3 names it and the argument goes. The card set agrees: all three Refinery modifiers grant +1 outbound. Refinery outbound-only, Grocer's inbound-only, Freight House the one two-way industry — which leaves exactly the one same-district pairing the rule above refuses. NOT REPRODUCED: cars left behind when backing up over them. Five layouts tried, including cars spotted at an industry; every one couples the lot. Three are pinned in `apply.test.ts`. One way to create such cars was closed anyway — `flyingSwitch` wrote its cut past `carsOn`. Both published replays that had gone dead were re-recorded; a rules change retires a save, and `harness.test.ts` is what catches it. The same change ships as v0.4.9e on the 0.4.9 line, branched from the v0.4.9d commit — the engine files these fixes touch are identical across the two lines, so the patch applied cleanly both ways. Also carries the two "Queued 2026-08-22, from playing on StartOS" TODO items that were staged before this work started (Games in Progress readability, and getting back into a game after losing a browser). They are notes, and items 9-12 below them are numbered against them. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_011nbvwWMef8CuEP6t5cgkTv |

v0.6.0 — saves survive a release, Employee Rotation is real, and the lobby
asks what game you want Three queued items. The last matters most. A RELEASE NO LONGER DESTROYS EVERY GAME IN PROGRESS. Four consecutive releases killed every game on the box, one of them a release that changed only how the board is drawn. The reasoning behind the refusal was always right — a move legal under old rules may not be legal under new ones, and half-replaying a save is worse than refusing it. The TEST was wrong: it compared engineVersion for exact equality, and that stamp is the package version, which moves for a CSS fix. Whether a save still replays has an exact answer, so it is now asked directly. loadGame reads the file and judges nothing; tryResumeSession replays the intents and reports the first one the engine refuses. A save stamped with a version this server has never run resumes fine provided its moves replay — verified against a file hand-stamped 0.4.9-ancient. One that genuinely does not replay is still refused, but the log names the move rather than two version strings: "move 3 of 8 (localOps.choose) is rejected by the current rules with OPTION_ALREADY_CHOSEN". fromMultiplayerSave had to stop lying first. It has always stopped at the first unacceptable intent and done so in silence, which was survivable only because the version gate meant a doomed replay was never attempted. Now that the replay IS the check, it returns where it stopped and why. Deliberately not done: resuming a partly-replayable game at its last good move. That silently rewinds a game to a position nobody played to while every browser holding a later Frame carries on unaware. Refusing leaves the file intact, so putting the previous version back still recovers it. EMPLOYEE ROTATION IS IMPLEMENTED, SISTER TRAINS IS DELETED. Two of the four optional-rule flags were read by nothing at all. Employee Rotation is four lines in advance.ts, because the seat/player split (D9) exists for precisely this rule: seating is the only thing that moves, so Revenue, hands, the Superintendent and whose turn it is travel with the player, and the Office, district, grid and any trains standing in it stay with the chair. Inheriting the district you move into is the point of the rule, not a side effect. "Left" is seat + 1, matching playerLeftOf. Sister Trains is deleted rather than built: Q9 records that the Second Section card supersedes it, and that card exists, so the flag was a toggle for a rule the game no longer has. THE LOBBY ASKS WHAT GAME YOU WANT TO PLAY. Creating a game asked for a name, a mode and a table size; every other dial was hardcoded. A Game settings block now carries the same set the solitaire dialog does — seed, starting hand, the three revenue rates, Days, the combined-Revenue floor, both collision caps, the opponent-card toggle — plus the three surviving optional rules. Mode and table size set the defaults and everything stays editable. The seed is honoured, so a game can be reproduced or compared. Verified: 682 tests pass (679 + 3). The rotation tests were mutation-checked both ways — disabling the rotation and turning the table the wrong way each fail the suite. Live: a save stamped 0.4.9-ancient resumed, an injected illegal move was refused by name, and a create with every dial set to a non-default value came back out of game.json with all of them intact, including seed 777. Two of my own assertions were wrong on the way and the tests caught them: the Fedora legitimately passes at Stage 12 (§5) so it cannot be compared against its own earlier value, and dispatchUsedToday is cleared at every Day boundary so it cannot mark a district. |

v0.5.0 — multiplayer Phases 2 and 3: a server that runs a game and survives being restarted
Phases 0-1 shipped in v0.4.0 (seat/identity split, per-player turn state, the Session boundary). This lands Phase 2 (server core, one game, no lobby) and Phase 3 (persistence and resumption) per docs/architecture/multiplayer.md §12. Phases 4-6 (lobby/reconnection, the 22 opponent-directed cards, StartOS packaging) are still ahead. Phase 2: src/server/session.ts hosts a game in pure logic (no sockets) on top of game.ts's existing Game/submit/currentActor/actionMenu; it verifies seat === currentActor(game) itself before calling submit, since submit() trusts its caller and a server can't. src/server/http.ts and index.ts add POST /api/game, GET /api/stream (SSE, per-seat), POST /api/intent, and static serving of dist/. src/sim/frame-delta.ts is a purpose-built per-seat board delta for one live push at a time. Found and fixed along the way: actionMenu(game, seat) only used seat for the hand field, so a server computing every connected seat's Menu would have handed the acting player's legal moves to a waiting seat. Verified with a live end-to-end smoke test (2-player game, two SSE streams, a rejected intent from the wrong seat, an idempotent resend) plus test/server/session.test.ts and test/redaction.test.ts. Not verified: an actual browser (none available in this environment). Phase 3: src/server/persistence.ts writes game.json and turn-timings.json, atomic-rewrite-then- rename. game.ts gained fromMultiplayerSave, fixing a narration-attribution bug found while testing it (fromSave's replay loop drops the actor argument, invisible in solitaire, unreadable the moment there's more than one seat — fromSave itself still has this gap, deliberately untouched). Verified live: server killed and restarted mid-game, both seats reconnected exactly where they left off. Two rules bugs found while building this: the New Train phase never implemented its car-placement round (every car of every train was placed by the Superintendent alone, in every mode, all along — now reads the round position off tray.consist.length); and victory conditions are now one shared, configurable GameConfig set across solitaire/competitive/coop instead of a fixed length lookup and a dead firstToTarget condition. Also folds in the three fixes already released on the patch line as v0.4.9b/c/d: a switching train's crew badge failing to draw once it left the Office square, an unload that always took the westmost car regardless of which was picked, and a legal decision that could render with zero buttons. docs/testing/0.5.0-test-plan.md and three reported-bug save files (docs/station-master-seed*.json) included for reproducibility. tools/jitsi-harness/ deliberately left untracked — unrelated side-project work, not part of this release. 635 tests, 0 failures. |

v0.4.9d — three playtest bugs: a train that looked gone, an unload that ignored the pick, a hang that wasn't one
Patched directly onto 0.4.9a rather than the in-progress 0.5.0 line. A switching train vanished from the board the moment it left the Office. `selectedTrain` in `officeSvg` (board-svg.ts), which gates whether a card draws a train's crew badge, was only ever assigned inside the `cell.adTracks !== null` branch — true for the Office card alone. A train standing anywhere else, which is everywhere it stands while actually being switched, drew no badge at all. Game state was never affected; confirmed against the reported save with the engine directly. Fix hoists the assignment out of the guard so it runs for any card with a train on it. Unloading always took the westmost car, whichever one was picked. `laborer.beginUnload` carried the player's chosen `carIndex`, and `check()` validated that specific car, but the `unloadBegan` event it produced carried only the car's type — the reducer that performs the swap re-derived the target with `industryTrack.cars.findIndex(c => c.loaded)`, which always answers the first loaded car in track order regardless of what was requested. Fix adds `carIndex` to the event and uses it directly. A legal decision could render with zero buttons, which looked exactly like a hang. The "where does this Extra start" decision is titled by `trainCardTitle`, beginning "Making up Extra X22…" — the same prefix `renderActions()` stripped from the action list on the assumption it only ever belonged to the separate yard-chip car-placement panel. With no tray yet being filled, that panel is null, so nothing rendered the Extra's decision either: a legal, correctly-computed option with no button anywhere on the page. Replaying the reported save found no engine deadlock at any step — the engine always had a move. Fix matches the exact title of the one group the yard-chip panel covers instead of a title-prefix regex. New tests for all three: a train parked on an ordinary facility card must draw its crew badge; three differently-typed loaded cars, unloading index 2, must leave indices 0 and 1 alone; the existing softlock regression test now mirrors the real render filter instead of only the raw menu, plus a deterministic test for the exact reported scenario. 590 tests, 0 failures. |

the Roster Pass: every train at the Office visible
Builds "The Roster Pass" / "Two Trains, One Card" (station display for multiple trains at one Office). The Office is the one square where more than one train may legally stand at once (one per A/D track), and CellView.train had room for exactly one — a second train at a busy Station was counted in the old A/D pips and never drawn. CellView.train -> CellView.trains: TrainView[], seat-filtered and collecting every match rather than the first (fixes a latent cross-district leak in the process: trainOnCard never checked seat). The A/D pips are replaced with one roster chip per A/D track, always, free or occupied; clicking a chip sets selectedCrew, wiring the board and the action panel to the same value. standingWest moves from CrewTray to TrackCard: two trays sharing one Office card need one shared split, not one each, and there is no such thing as "west of one particular A/D track". No save migration — Save replays through the engine — and a stale value on an emptied card is inert because nothing reads a split with no train standing there. The Division map's Office cell is now sized by A/D capacity rather than occupancy, so it holds still as trains arrive and leave; chips lay into fixed slots instead of centre-spreading onto the Limits cards either side. 584 tests, 0 failures. Verified end-to-end against the built app and a direct render of a 4-train Terminal (screenshotted).

v0.4.8 — the Limits bound the whole district, the nine spots really are nine, and an action points at its square

v0.4.7 — the switching game: track order, the cut on your own card, and four rules
Eight play reports and one design that had been written up and not built. The
through-line is switching: what a card can hold, which end of a train a cut comes
off, which way a train meets cars standing on the line, and what the board and the
log say about all of it.
TRACK ORDER FOR STANDING CARS, AND THE CUT ON YOUR OWN CARD
Two reports turned out to be one root cause. `TrackCard.standing` claimed "in track
order (§A.3)" and had no defined orientation at all, while `CrewTray.consist` does
(nose first, relative to facing) — so every transfer between them was a conversion
nothing performed. §A.3 says what it should be: cars occupy the track "in the same
order they originally held, left-to-right". Left-to-right is west-to-east, and that
is now the defined orientation of `standing` and of an industry track through
`carsOn`. It is the board's orientation, not the train's, so it does not change when
a different train touches the card.
- Setting out is batch-invariant. Four cars at once, four singles and two pairs
parked three different orders, one of them physically impossible. Successive
cuts off the same end stack up towards the engine, so the insertion point is the
train's own place in the row.
- Approaching a cut from either end now mirrors. `couples` is built nearest-first
along the direction of travel and reverses onto the nose, so the farthest car met
ends up nose-most — which is what makes a run-around worth its Move.
- A train no longer drives through its own cut. The walk began at the neighbour of
the start square and never read the start card, so a crew could set cars out and
pull straight away from them. Coupling is mandatory (§A.4) and your own square is
no exception; the cut counts against the four-car limit. Setting out off the end
you are not leaving by still works.
`CrewTray.standingWest` records where a train stands among the cars on its card — a
train may set out off both ends on one square, so which side a cut is on is not
recoverable from the array alone.
On the board, the cut is drawn split at the train — west cars left, east cars right,
engine in the gap — and each car's tooltip says whether it stands ahead of or behind
the engine. The history says which end a cut came off, and a move's button separates
"takes your own boxcar back off this card" from cars found standing on the line.
Decided: taking your own cut back on the square you are standing on is UNDOING the
drop. It is exempt from trains 3/4's per-location freight budget, X13's "drop but not
pick up" and X22's "empties only", and it refunds the budget the drop spent.
Otherwise a legal-looking drop becomes silently one-way.
Measured, 200 paired seeds, developer bot: -0.55 revenue (t = -3.63), freight revenue
1.11 -> 0.56. That cost is the bot's, not the rule's — its trains run engine-first,
so at a stub industry it sets a car out between itself and the only way out, and the
correct play is §A.5's facing-point move, which is the cross-turn planning TODO.md
already records as out of reach of any bot. Filtering self-recoupling moves out of its
options took recoupling from 625 of 1,029 set-outs to 101 of 677, and all 101 that
remain are that case. Read the number as a bot measurement, not a balance one.
THE SUPERINTENDENT'S RULING NAMES THE TRAINS IT IS ABOUT
Reported: the Superintendent could not tell which train he was clearing. The heading
asks the question now — "may Train 6 follow Train 4 onto the same Mainline card?" —
and the trains moved to the FRONT of each button, because the button splits its label
at the first em-dash and showed only the head.
AN INDUSTRY TRACK HOLDS FOUR CARS, LIKE EVERY OTHER CARD
Reported at undo 188: "we wanted to drop two cars, but were only allowed to drop one."
An industry track was built as long as its box count, so a one-box industry had room
for one car. Box count is how much WORK an industry can hold, not how much RAIL it
has. Ordinary track was the other exception, unbounded; both are gone and every card
holds four.
THE FREIGHT AGENT MAY STAGE A LOAD BEFORE THE CAR IS THERE
§6.3 asks nothing of the industry track — the empty car belongs to §9.3's Load the
car, which is the Laborer's action. The gate now lives only there, so cargo can wait
on the dock while the car to ship it in is still being switched in. Nothing can jam:
a load in a green box is waiting, not stuck.
THE TRUCK DOCK UNLOADS, AND BRINGS NOBODY
+1 inbound, no Laborer. It printed +1 outbound and +1 Laborer, which made it a
longer-host-list copy of Forklifts. Beside Packing Sheds it now does nothing at all,
and the hand tooltip says so before it is played.
Also in this release, from the days before: Mainline card tooltips computed from the
crossing rule; an Extra starts from the Division Point its number sends it to; a
modifier's suppressed grant comes back when a Whistle Post is upgraded; the Oil
Refinery and the Grocer's Warehouse ship as well as receive, per the card reference;
and the dormant defences name the attack they answer. `.claude/` is now gitignored —
it holds Claude Code's worktrees, i.e. a second checkout of this repository.
570 tests, typecheck clean. The three published replays were re-recorded twice —
legality changed, so bot play changed. Full detail in CHANGELOG.md.

v0.1.0 — undo, the crew's reach on the board, workers on the card, and four engine bugs
Fifteen items from two playtest sessions. Three that read as drawing faults were engine bugs: cars could be added to a train that was not being made up (50 offers in 8 games), the make-up panel merged two trains and could couple a car to the wrong one, and an Office upgrade silently deleted what a Modifier had added. A fourth was a sentinel inside a coordinate's own value range — a Mainline placement travelling as row -1, which is an ordinary district row. Trains are now drawn the way they stand: west on the left, nose toward the way the engine faces, on both the district card and the Division chip. Undo steps back through the game by replaying the save without its last intent. The switching walk keeps its rejections, so the board can say why a square is not offered. Laborers and Porters are on the card, and the rule that a district only grows outwards is finally written down. Versions start here: third digit for fixes, second for a feature set, 1.0 for a release.
