v0.7.5 — solitaire asks before it deals, the same way multiplayer already does

A new #solitairesetup screen in play.html asks the full shared game-options
block — type, starting hand, Extra start, revenue, victory conditions,
optional rules — before a genuinely fresh visit deals a game. A saved game,
an explicit ?seed=, or a URL a Deal already wrote all skip past it, same as
?lobby already skips the front doors on an invite link.

The in-game dialog, the lobby and this screen now share one
wireGameTypeBlock()/commitNewGame() pair instead of the dialog carrying its
own copy of the questions.

859 tests pass. Not yet played in a browser.

+
+### Solitaire asks first, the same way multiplayer already does
+
+Jesse: "let the user choose their options like the start of a multiplayer game"; "asking first is
+the only path." A bare visit to `play.html` used to deal a game on the spot, at whatever defaults
+`gameOptionsFromUrl` fell back to, and the only way to see or change a setting was to open the
+in-game "New game" dialog after the fact — compare a hand you already have, not one you are about
+to be dealt. The lobby has asked this question for every multiplayer game since v0.6.0; solitaire
+never did.
+
+A genuinely fresh visit now lands on a new `#solitairesetup` screen first: game type, starting hand,
+where an Extra may start, the three revenue rates, victory conditions, and the three optional rules
+— then a Deal button. A saved game, an explicit `?seed=`, or a URL a Deal already wrote (`hand` is
+the field every write always sets, so its presence is what tells the difference) all skip straight
+past it, the same way `?lobby` already skips the front doors on an invite link — those are not "no
+plan yet", they are a choice already made, elsewhere.
+
+**One shared block instead of two copies drifting apart.** The in-game dialog, the lobby, and now
+this screen all drive the identical `settings-form.ts` block through one new function,
+`wireGameTypeBlock()` — factored out of what used to be dialog-only code. Only Solitaire can be
+dealt outside the lobby, so the setup screen shows the other four types exactly as the dialog always
+has: present, disabled, with a note pointing at the Multiplayer door. Committing an answer — from
+either the dialog or the setup screen — goes through one `commitNewGame()`, which builds the URL and
+navigates; `start()` is still the only place that turns a URL into a game.
+
+Prefilling is deliberately left to the caller rather than folded into `wireGameTypeBlock` itself:
+the dialog opens on the game CURRENTLY IN PLAY, so redealing to compare keeps comparing against it,
+while the setup screen opens on the plain Solitaire defaults, since there is no live game yet to
+read.
+
+`index.html`'s door copy changed to match: "Start a game" reads "Set up a game" now, and the blurb
+states the floor (15, not "20 Revenue") since that is what a player is agreeing to before they deal.
+
+859 tests pass. **Not yet played in a browser** — verified by `tsc --noEmit`, the full suite, and
+reading the diff, not by loading `play.html` fresh and clicking through it.

+
+## 0.7.4 — 2026-08-29
+
+Three rules issues off the tracker, in the order Jesse asked for them: #13, #5, #19. All three are
+rules Jesse has designed or redefined, and two of them turned out to be rules the code claimed to
+have and did not.
+
+### Some Extras must run loaded (Gitea#13)
+
+X17 Campaign, X18 Circus and X19 Military now prefer loaded cars at make-up — "if not loaded, then
+empty, and if none available, run without". It is a preference ORDER, so the rule is asked of the
+Division Yard: an empty is refused only while the yard can still supply a loaded car this train
+would take, per category, and once it cannot the empty is legal and the train may depart short.
+
+The per-stop point is **once per Office Area** rather than once per game (Jesse: "in a multiplayer
+game, each player could score if the circus stops in their area"), and only when the train is fully
+loaded — every non-caboose car, with a coach counting as loaded when occupied. That last detail is
+what makes the rule work for the Campaign Train, which carries one coach and no freight, so "fully
+loaded" is exactly "the candidate is aboard". X17 also GAINS the point; it had `stopThenExpedite`
+and no scoring rule at all.
+
+**Two bugs found doing it.** `ConsistSpec.emptiesOnly` was declared on X13 Appleseed, rendered to
+the player as "(empties only)", and enforced nowhere — the same rule as this issue pointing the
+other way, so it would have been perverse to add one and leave the other. And a set-up out on the
+Mainline paid its point to PLAYER 0 whoever was playing, because `playerAtSeat` needs a seat and off
+the grid the fallback was `0`; scoping the rule to Office Areas removes that rather than patching it.
+
+### The Yard Office is offered, reachable, and can be run into (Gitea#5)
+
+It was implemented, in a form missing all three of the rule's conditions: a qualifying train was
+TELEPORTED onto the 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 in.
+
+Now it is offered to the district's owner; reachability is the engine's own move walk, which already
+means what the card means; and cars on the lead collide. The walk COUPLES standing cars rather than
+treating them as obstacles, because that is what a switching move does — so what an arriving train
+would have coupled is what it is about to hit, and `destination.couples` turned out to be the
+fouling signal with no new machinery. Per Jesse's ruling the two failures are kept apart: no route
+means no offer and the history says why; a route that exists but is fouled is offered, and taking it
+crashes.
+
+**This needed a refactor that #19 then reused.** `pendingDecision` was one question asked of one
+player, and `currentActor` hardcoded that. It is a discriminated union now, with `decisionActor` as
+the single place mapping a question to whoever answers it; six copies of `pendingDecision !== null ?
+superintendent : currentActor` across engine, sim, web and tests collapse into `actingPlayer`.
+
+### Red Flags, redesigned (Gitea#19)
+
+The old card protected a stopped train out on the Mainline: offered 4,212 times and played 4 across
+600 games. It is replaced outright by a flag planted on one side of your own Limits, holding the
+next train from that direction — "Flag East holds westbound trains" — spent on the train it stops.
+One card, one train, so there is no lifting action to build and a flag cannot strangle the Division.
+
+It can also be played **out of phase**: when an arrival would certainly collide and the district's
+owner holds the card, the phase breaks in with the question. Offered only to somebody holding one,
+because a prompt with a single button is not a choice and would leak that a collision is coming.
+
+**The bot still never plays it, and the reason changed — measured, not assumed.** It now takes the
+out-of-phase prompt unconditionally, since the engine has already established the danger. Over 200
+solitaire games it plays ZERO, because the prompt needs an arrival that would collide (about one
+game in seven) to coincide with holding the card from a three-card hand out of 121. The anomaly
+exemption in `sim.test.ts` stays, but its comment no longer claims the bot is unwilling; what is
+left to fix is the half of the card a human uses — planting a flag on purpose to buy switching time.
+
+**A bug the redesign walked into**, recorded because the next interruption will meet it too: the
+flag was originally taken down in a `reduce` case, which never fires for an event `advance.ts`
+emits — the phase driver mutates and then describes. The flag stayed up and held every train that
+came. `test/events.test.ts`'s unreduced-event registry is what makes that class of mistake visible,
+and `redFlagSpent` is now on it deliberately.
+
+858 tests pass.
+
+---
+
+## 0.7.3 — 2026-08-29
+
+Two issues off the tracker, and they are halves of one thing: the end of a game. Gitea#11 stops the
+game being over when the timetable runs out, and Gitea#16 replaces the four lines that were shown
+there with a results screen worth reading. Neither ships on the 0.4.9 line — Jesse's call
+(2026-08-29): that line may be complete, and these are not fixes people mid-playtest need.
+
+### The game asks before it ends (Gitea#11)
+
+"When game ends allow players to continue playing if they wish… don't force end."
+
+The rule, decided with Jesse: **the official result is settled at the original game length and never
+changes.** In a five-Day game extended to eight, the winner is whoever led at the end of Day 5.
+Extending grants exactly **one** Day and the question is put again at the end of it — solitaire the
+player decides alone, multiplayer it is unanimous and one refusal ends it there and then. Only
+days-based endings offer it: a §3.4 collision breach is final, during an extended Day exactly as
+during the scheduled game, because a railroad declared unsafe does not carry on regardless.
+
+**It could not be a client-side change**, for three reasons that each rule out the others' fixes.
+`check` refused every intent once `status` left `active`; `server/index.ts` never loads a `finished`
+game back into memory; and a save is `{ seed, config, history }` replayed through the engine, so a
+"continue" the history does not record did not happen — the extended game would evaporate on the next
+reload, Undo or restart. So there is a fourth status, `awaitingExtension`, and the vote is an intent.
+
+`config.days` never moves. `extraDays` counts the borrowed Days, and `official` — the outcome, the
+standings and the statistics, frozen at the first ending — is what the results screen reports. That
+freeze is done by a wrapper around `advance` rather than inside `checkVictory`, so it happens *after*
+the last Day's events have been counted rather than before them.
+
+**Three bugs found while testing it, all of which would have shipped:**
+
+- **A saved game with a vote in it could not be resumed** — `NO_ACTOR`. A history is a flat
+  `Intent[]` with no seat written down; the replay derives who acted from the turn order. That works
+  for every other intent, `mainline.clearance` included, because there is exactly one seat it could
+  have been. Not here: every seat may vote in any order. `game.extend` therefore carries its voter,
+  uniquely, and the server checks it against the seat it authenticated.
+- **An all-bot game hung on the question for ever.** `driveBots` loops on `currentActor`, which is
+  null the moment the game stops, so it cannot cast a vote; the bot-vote driver returned early when
+  there were no humans to follow, and nothing ever asked. With nobody to follow, the bots' own answer
+  stands — no — and a bot-only game ends on the timetable it was dealt.
+- **The balance harness became unbounded**, which is how the third one announced itself:
+  `test/sim.test.ts` went from under a second to never finishing. `randomBot` picks uniformly among
+  its legal options, so once the two votes were among them it took another Day about half the time —
+  and because a table may go on granting Days indefinitely, every seeded game ran to `playGame`'s
+  50,000-turn cap instead of a couple of hundred. Giving `developerBot` a policy was not enough: the
+  guarantee has to hold for every policy, so **`playGame` itself declines**. A simulated game plays
+  the timetable it was dealt, whatever the bot would have voted.
+
+All three have regression tests.
+
+Bots never lead. They agree only once every human has agreed, which is the rule Jesse set: "bots will
+not disagree with the human. Humans get to vote first."
+
+### The results screen (Gitea#16)
+
+`GAME OVER — revenueFloor` was not a message. It was `outcome.reason`, an internal enum, interpolated
+straight into the page at the one moment the game has the player's whole attention. Every reason now
+has a sentence with the game's own numbers in it, and that fix alone answers the issue's "why did the
+game end?".
+
+Around it: the result and the winner, the standings, the rules the game was actually dealt under, a
+per-player breakdown, and **the railroad** — trains through the Division and how many of them did any
+switching en route, loads made up and broken, passengers worked, cars switched, trains destroyed and
+what they took with them. It shares the Day-end dialog's standings, target and collision blocks rather
+than reimplementing them, because two screens reporting the same game must not be able to disagree.
+It opens itself once per ending and leaves a button to reopen it, which is what stops Gitea#11's
+extended play costing you the results.
+
+**"I don't know if we keep statistics on…"** — nothing was being kept, and now `state.tally` is,
+folded from the event stream. Hooked at `applyIntent` and at `advance`, because `reduce` never sees
+the phase driver's events and those are exactly the interesting ones: `trainCompleted`,
+`trainsDestroyed`, `trainStoodStill`. The test that matters asserts **exactly once** — it plays real
+games, counts the event stream independently, and checks the tally against that count, so a fold
+hooked twice or nowhere fails whatever the seed.
+
+Nothing in the rules reads the tally, so adding a counter is always safe. It rides the `Frame`, so
+multiplayer gets the same numbers as solitaire from one implementation — and `test/redaction.test.ts`
+gained a case proving a tally never carries a card id, since that is a property of what `tally.ts`
+chooses to count and not something the types enforce.
+
+**"Longest an engine sat on a siding" is not in this pass, and the issue comment was wrong about
+why it could be.** That comment said `trainStoodStill` "is emitted per Stage, so a run of them is
+exactly the 'sat on a siding' streak you describe". It is not. Reading `advance.ts` rather than
+trusting it: the event fires only for a train whose profile sets `stopEarnsPoint` — the X18 Circus,
+the one card in the deck that pays for standing still — and `stopPointClaimed` makes sure it can
+never fire twice for the same train. The streak was built, shipped nothing but "1 Stage" against a
+raw grid coordinate, and has been taken out again. The engine has **no per-Stage "this train did not
+move" signal at all**, so this needs one before it can be answered; `TODO.md` #36 records that. What
+is reported instead is the Circus set-up itself, which is a real thing that happened.
+
+**Badges are not here.** The issue asks for them in a second pass after "a whole conversation
+brainstorming session", and that is where they belong. The tally keeps the raw material — the
+switching join for "switching master", the standing runs for "longest engine sat on a siding" — and
+because the statistics are *derived* rather than recorded, a second pass can add any of them
+retroactively to games already played and saved.
+
+### Also
+
+- **A recorded replay plays to its end.** `save-replay.ts` stopped where `currentActor` went null,
+  which since Gitea#11 is the extension question — so a newly recorded file would have replayed to a
+  question nobody answered rather than to a finished game. It declines, like every other bot driver.
+  The three files already published in `public/replays` predate the vote and stop on the question
+  when replayed; `test/harness.test.ts` accepts that as the end of their history, since it is.
+- The status line stops lying past the last Day. It read `N of TARGET · D Days left` with both halves
+  false; in an extended game it now reads the Day and how far beyond the timetable play has got.
+- `objectiveOf` paces against the timetable actually being played rather than `config.days`, which
+  otherwise reported "the last Day is over" through every extended Day.
+
+---
+
+## 0.7.2 — 2026-08-26
+
+Five issues off the tracker. Two are engine bugs a player hit at the board, two are the design
+catching up with rulings from RAR that the code had got wrong or never had, and one is the Division
+map being redrawn. The first four ship as **0.4.9h** on the 0.4.9 line; the map does not — it is a
+multiplayer redesign, and pushing one of those into a build people are mid-playtest on invalidates
+the feedback.
+
+### A 45° leg is part of the row (Gitea#17)
+
+**REPORTED:** "Cars were West to East Caboose, Loaded boxcar, Loaded boxcar, Loaded boxcar. After
+backing into that square cars were attached to the train Loaded boxcar, Loaded boxcar, Loaded boxcar,
+Caboose, Engine." The caboose came back next to the engine instead of at the far end, which also
+leaves the train badly made up under §8.2.
+
+The square was a `sw` CURVE and the train backed in through its SOUTH leg. `standing` runs west to
+east, and both places that walk that row asked the PORT which end they were at: `exploreMoves`
+reversed the row for an `'e'` entry and nothing else, and `cutTowards` answered "you meet nothing"
+for a north or south exit. Neither is a property of the port. A 45° leg leaves through the MIDDLE of
+its edge, so its end of the run is whichever end the arc does not reach — a `sw` curve's south leg is
+the row's EAST end and an `se` curve's south leg is its WEST end.
+
+`rowEndAt` answers it from the card, and `cutTowards` is narrowed from `Port` to `'e' | 'w'` so the
+type checker forces every caller to resolve rather than leaving a fourth to be found later.
+
+**THE SECOND HALF WAS LIVE TOO, and is a report we had failed to reproduce.** With `cutTowards`
+returning nothing for a leg, a crew standing on a curve pulled out through it and DROVE AWAY LEAVING
+ITS OWN CUT STANDING — against §A.4's mandatory coupling. That is "cars left behind when backing up
+over them", carried as NOT REPRODUCED since 2026-08-22; the earlier sweep had tried that case only
+with an east or west exit. The report's second sentence — "I can later drive right through them" —
+is still unexplained and still open.
+
+### The deck is the sheet (Gitea#14)
+
+`docs/Deck cards5.xlsx` is in the repo, and every count in the catalogue is now its count. Track is
+halved: 16 straights, 8+8 curves, 8+8 turnouts, sharp curves at zero — which is where they already
+were, and where sheet 5 independently puts them.
+
+**BOTH LONG-STANDING MULTIPLIERS COME OUT WITH IT.** The Q12 office doubling (14 → 7) and the Gap 12
+industry tripling (27 → 9) were measured against a deck holding 96 track cards, and halving the track
+turns the tripling backwards — the deck keeps dealing industries while the district stays too small
+to reach them. Measured over 300 bot games on identical seeds, 96 track with the multipliers / 48
+with them / 48 without: reefer cars set out by a crew **49 / 0 / 39**, mean revenue **−0.20 / +0.22 /
++0.27**. The middle column wipes out the reefer chain completely. The sheet's own density is the best
+of the three on both counts.
+
+Q12's own failure was re-measured rather than assumed: 43 of 100 games now never upgrade off a
+Whistle Post, up from 25 — but they average −0.2 revenue against +1.4 for games that do, where the
+gap used to be −6.0 against −0.4, and collisions fell from 26 per 100 games to 6. Staying at a
+Whistle Post is now common and survivable rather than rare and fatal.
+
+Everything sheet 5 does not list is dealt ZERO copies rather than deleted, so the design stays
+visible and the rules stay implemented: the Telegraph/Telephone/Radio dispatching ladder, Facing
+Point Locks, Flying Switch, Section House and Vandalism — all confirmed by Jesse as deliberate
+removals — plus Poling and the sharp curves, which were already there. Card for card, **84 rows agree
+with the sheet**; the only ones that do not are the ten Safety, Event, Inspection and Space-use cards
+it adds that are not built, held out until they are.
+
+### A rail may stop dead against its neighbour (Gitea#15)
+
+Filed as "track placements must connect", against a right-hand curve laid with its north leg against
+an Ice House and the turnout below pointing at its portless south edge. **RAR reversed it on review:**
+the placement is fine, and a stub like that has a use — a siding to park cars on. What he asked to
+confirm instead is that no train can traverse the gap.
+
+It could not, and cannot: `exploreMoves` gates every hop on `joins`, which tests both ports AND that
+two 45° legs lie on the same diagonal. That was already true and simply unpinned; `track.test.ts`
+now holds it against the reported geometry, including a check that the curve IS reachable from the
+side that joins, so the negative test cannot pass on a card that is merely unreachable.
+
+A per-edge placement check was written and then taken out, along with a matching guard on
+`checkTurnoutUpgrade`. Both are documented in place as deliberately absent, because this is exactly
+the rule someone will "fix" again. A Modifier is scenery (Jesse): a rail pointing at a building is
+fine.
+
+### Crossing a Mainline card is regions, not miles per hour (Gitea#3)
+
+**REPORTED:** a train taking two Stages to clear Double Track, which prints 60. RAR, on review:
+"Ignore speed signs, they are just graphics. Regions shown on cards indicate how many stages it takes
+to cross."
+
+Two recorded rulings are superseded together — Q1, that the printed 60/30 are crossing time, and Q2,
+that a Slow train adds a Stage to every card. Q2 is what produced the report. Cards carry a region
+count now and **where a train STARTS is what varies**: Plains 1, Double Track 1, Trestle 1, Curves 2,
+Tunnel 2, Heavy Grade 3. Fast/Slow is read on Hilly and nowhere else — and Hilly no longer reads the
+consist, which had a fast freight crossing slower than a slow passenger train. The grade modifiers
+move the start rather than cutting the clock: Helpers start an uphill train a region on, Brakeman a
+downhill one, Airbrakes another again. The Uncontrolled Siding and the Interchange print a back
+region that is not road: a train through starts past it, one arriving to find the siding occupied
+takes it and runs a region behind, and an Extra beginning its run at an Interchange starts there.
+
+**THREE THINGS WERE MISSING RATHER THAN WRONG.** With Plains now one region, a following train is in
+the same place as the train ahead the moment it enters — and nothing tested that, because the
+catch-up check sits inside `stagesRemaining > 1`, which a one-Stage crossing never reaches. That is
+the case ABS describes ("the train moving onto the card is instead held back") and it needed
+building. ABS was also holding SILENTLY on the Office and Division Point paths, so the one card whose
+purpose is preventing a wreck did its job invisibly. And `collide` never released the A/D track,
+which did not matter while every collision happened out on the road — a train destroyed as it LEAVES
+is still standing at the Office.
+
+The Uncontrolled Siding was marked "trains may pass", which skipped the collision test altogether and
+made the siding do nothing at all. It is `false` now, with the siding entry doing the work.
+
+Measured: on the Mainline cards of a 3-player Division, a fast train pays ~5.6 Stages against ~5.4
+before and a slow one ~6.0 against ~9.4. **Fast traffic is unchanged; slow traffic is about a third
+quicker**, and the gap across a Division collapses from roughly four Stages to under one — so Q2's
+recorded consequence, that every Slow train is still on the road when the next Day begins holding its
+Crew Tray, no longer holds and `players + 3` is due a re-examination.
+
+Two effects are recorded in `TODO.md` rather than acted on: freight share fell 8% → 5% and completed
+freight loads got scarcer, which runs against the obvious expectation and nobody knows why yet; and
+the bot stopped playing Red Flags — offered 4,212 times in 600 games, played 4.
+
+### The Division is one row (Gitea#18)
+
+**REPORTED:** "track design should not be horseshoe / square, but a single row… Division map should
+not show any office area detail."
+
+It was laid out around a table — one row for a single seat, two facing rows for two, a horseshoe for
+three, a square for four — on the reasoning that players sit around one. Three reports came out of
+that, and the one that decided it is that **east stopped being to the right**: a player's east could
+be drawn south, west or north depending which lane their district landed in, on a map whose whole job
+is saying which way a train is going. `WDP · ML · Office · … · ML · EDP`, left to right, and the
+buffer stops simply face outward at the two ends.
+
+An Office no longer expands into its Running Track either, so the map stops carrying every straight,
+turnout and Limits sign of every district — that is the Office map's job, and it draws them properly,
+with the rails. It also stops the Division map growing sideways every time somebody lays a card.
+
+The trains stay, in two registers: those holding an A/D track ON the rail, and crews switching in the
+district UNDER it — the distinction drawn as position rather than colour, because that is where those
+trains are. Each chip carries its number, a direction arrow and a car count, with the consist and the
+train's printed card on the tooltip. Every district cell is four chips two-by-two regardless of tier,
+because a Whistle Post with one A/D track can still hold four trains when three of them are crews,
+and sizing by occupancy is what "The Roster Pass" fixed. 1,580px wide at four players against 842
+before, drawn at 1:1 so it scrolls rather than shrinking — Jesse's call, "zooming and scrolling
+worked fine".
+
+This supersedes `TODO.md` item 24 outright and makes 19, 20, 21, 22, 25 and 26 irrelevant; item 27 is
+fixed.
+
+### Six test fixtures that pinned a seed and meant "a game like this"
+
+Every one of them broke on a rules change and none was about the rule that changed: the deck's SIZE
+moves the RNG stream, so any count change re-deals every fixture that names a seed.
+`mainline-cards` now searches for a Division holding a single-track card, `multiplayer` for a game
+that reaches Day 3, `web` clicks every play verb rather than assuming the first goes on the board and
+searches for a seed that builds a board, and the `sim` commodity samples were re-measured — a tank is
+first set out at game 216 now, unload Revenue at game 46. A seventh, `mainline-cards`' `hand()`
+helper, threw when a card was not in the deck, so dealing Flying Switch zero copies took five passing
+tests of an unchanged rule with it; it mints one now, which is the point of keeping a row at zero.
+
+**And one real bug, in a test.** `the game conserves Rolling Stock` went red claiming the engine had
+conjured three cars. The engine was right: Gap 2c sends a wreck's cabooses to the Division Yard and
+everything else to Classification, destroying nothing. The test subtracted the wreck's consist from
+the expected census — a rule the engine does not have — and the branch had never executed, because
+none of its six seeds had ever collided. The census is held flat unconditionally now, which is both
+the true invariant and stricter than what it replaced.
+
+---
+
+## 0.7.1 — 2026-08-25
+
+Four issues off the Gitea tracker, all of them things a player saw at the board. Two are engine or
+page bugs, one is a rules ruling that supersedes a ruling from three days earlier, and the fourth
+turned out not to be a bug at all — the fix there is that the game now says so. The same four ship
+as **0.4.9g** on the 0.4.9 line.
+
+### A caboose is not a load (Gitea#8)
+
+**REPORTED:** X22 Pee-Dee could not couple a caboose — including the one it was made up with. Drop
+it at the end of a sweep and it was stranded there, which makes a train whose whole card is a
+restriction ("may only pick up MTs") unplayable rather than merely restricted.
+
+`ROLLING_STOCK_SUPPLY` mints all six cabooses as `{ loaded: 6, empty: 0 }`, because §2.2's "a
+coloured car is loaded, a white car is empty" is doing double duty there as a PIECE COUNT and there
+is no white caboose to make a train up from. So `.loaded` carries two meanings, and the second one
+escaped in exactly one place: `pickUpEmptiesOnly`'s `fresh.some((c) => c.loaded)`. Every other read
+of the flag in `apply.ts` is already scoped to a coach or to a named car type.
+
+`carriesLoad` now answers the question the rule is actually asking — a caboose carries the crew, not
+freight, so it is never a load — and the restriction itself is untouched: a loaded car alongside the
+caboose still refuses. `trainRules` says so on the card ("A caboose is not a load"), because a player
+reading "EMPTIES ONLY" has no way to know which reading the game took.
+
+### The Day rolls over and says so (Gitea#10)
+
+**REPORTED:** "As the game rolls off the end of the day, you get a dialog saying such. Hard to keep
+track of time."
+
+Nothing on screen was wrong. The clock, the turn chart and the timetable all said which Day it was.
+What is wrong is WHEN it changes: a Day turns over inside the phases that run themselves, so it
+happens between one click and the next, while the player is watching the board and waiting for their
+turn. The two transient signals the page already had are both gone before that — the phase banner at
+2.6s, the announcement flash at 4.2s. A modal is the whole request: it stops, and it waits.
+
+`dayEndHtml` writes it from the frame AFTER the rollover, so the Day that ended is `f.day - 1`.
+It carries the standings in **Revenue order** rather than seat order (the question at the end of a
+Day is who is ahead), the Days left to run, and the combined target — reported against the whole
+table's Revenue, because `minCombinedRevenue` is a combined floor and one player's score against a
+four-player target reads as hopeless when the table is comfortably ahead. Collisions appear only
+where §3.4 actually scores them: competitive and co-op, and only when a dial is non-zero. A solitaire
+game carries the default dials and enforces neither, so printing a collision budget there would put a
+rule on screen that this game does not have.
+
+Three suppressions, each of them a way it would otherwise lie:
+
+- **the first frame** — arriving in a game already on Day 3 is not Day 2 ending, and a page reloaded
+  mid-game would announce a rollover that happened before it was watching;
+- **the Day going DOWN** — that is Undo stepping back across the rollover, not a Day passing. Undo
+  also clears `lastDay`, so replaying forward through the same rollover does not announce it twice;
+- **the Day the game ends on** — the outcome panel is the thing to read then. Verified by playing a
+  full solitaire game through: the dialog fires four times in a 5-Day game, not five.
+
+### A Timetabled train may be thrown away (Gitea#9)
+
+**REPORTED:** "Timetabled trains are at the choice of the player — they can either play or discard.
+If someone else wants to pick it up, they are more than able to. The reason: I don't want, if you
+decide to play a game longer than five days, to decide that maybe there are too many trains, the
+stations are jammed, and the railroad doesn't need any more. You can toss it. Someone else might
+disagree and pick it up."
+
+This **supersedes Gitea#6**, shipped three days earlier in 0.6.2, which made every train card
+unconditionally undiscardable. Two things narrow it:
+
+- an **Extra** is still never discardable. It never joins the timetable, so it can never be what
+  jams it, and the only rule it would dodge by being thrown away is the hand limit;
+- the Timetabled half is a **New Game setting** — `discardTimetabled`, on by default — because
+  Jesse's reasoning is explicitly about games run LONGER than five days, and a five-Day game may well
+  want Gitea#6's pressure back. Jesse asked for it as a setting on this line and as the plain rule on
+  the 0.4.9 line, which has no scaffolding for one; both play the same game at main's default.
+
+**The second half of the ruling needed no code at all.** "Someone else might pick it up" — a discard
+already goes face-up onto a Department pile, and a Department pile is exactly what a rival draws
+from. Only the first half was a change.
+
+**One place decides, and the card says which rule refused.** `keepReason` returns the sentence a
+player should read, or `null` if the card may go; `check`, the hand panel and the blocked "End Local
+Operations" button all ask it. It returns a SENTENCE rather than a boolean because there are now two
+distinct reasons — "an Extra is never discarded" and "not in this game" — and the panel that used to
+hard-code one of them would now tell half the players the wrong thing. It reaches the page as the
+Frame's `handKeepWhy`, replacing text `panels.ts` and `main.ts` each wrote for themselves.
+
+**Two places would have dropped the setting silently**, both found by looking rather than by `tsc` —
+`HouseRuleOverrides`' fields are all optional, so omitting one compiles and falls back to the
+default. The New Game dialog's close handler builds its own `houseRules` object (the comment
+directly above it warns of exactly this: "a setting missing from here is a setting the dialog
+silently discards"), and `presets.ts`'s Frame-to-config path, which is how a JOINER is shown someone
+else's game — a setting dropped there shows them a rule the table is not playing.
+
+**Gitea#6's corner survives, narrowed.** A hand of four undiscardable trains still has exactly one
+legal way on — play one — with nothing in the engine computing "you must play a train". With the
+setting on, the only hand that reaches it is four Extras; with it off, any four trains, as before.
+Both are pinned by tests.
+
+### Why nothing is moving on the platform (Gitea#2)
+
+**REPORTED:** "The Sparrow pulled into the station with two loaded coaches. There are two passengers
+on the platform. Four porters. My thought was to unload two and load two. I never get the chance to
+load the last two."
+
+**The engine is not deviating from the rules**, and this was checked step by step against the
+reported save. §9.2 discards the white coach into the Classification Yard on boarding and draws one
+from the Division Yard on de-training; §2.2 returns the Classification Yard only when the Division
+Yard is empty. All three are implemented exactly. What bites is the interaction: both halves of every
+passenger cycle consume coaches one-way, and a single global refill condition over a pile of six
+commodities means they do not come back. Traced over the reported game the coach pool goes 8+/8− on
+Day 1 to 0+/1− by Day 5, with eight coaches stranded in Classification behind ~60 other cars.
+
+**Jesse's ruling is that the shortage stays** — "it is possible to run out, that's part of the
+strategy" — so the three balance options written up in `TODO.md` are declined rather than deferred.
+
+What was unambiguously a bug is that the game said **nothing**. A Porter action that cannot be taken
+is simply absent from the menu, and `impediments()` — the panel whose entire job is "why is nothing
+moving?" — opened with `if (!f || f.kind !== 'freight') continue`, so a platform had never had
+anything to say for itself. The player was not merely blocked; he was given no reason.
+
+A Passenger Facility now reports both directions: passengers standing with no train to take them, a
+train whose card bars Porters from working it, a Terminals-only train at a lesser Office, every coach
+already full, the red slots full, the same-district rule, and the coach shortage itself — that last
+one naming how many coaches are sitting in Classification and the condition that brings them back,
+because a yard visibly full of cars that will not yield one coach is the state that looks like a
+broken game. The reason text comes from `passengerRefusal`, the engine's own predicate (exported for
+this), so what is on screen is the rule that actually refused rather than a second guess at it.
+
+**A second defect fell out of fixing it.** The row's name is read off `card.geometry.facility`, which
+a Passenger Facility does not have — it rides on the `office` card — so every passenger impediment
+would have read `facility 0,0` beside a freight row saying `mineTipple 1,-3`. It is named by the
+Office Area's tier now (`terminal 0,0`), and there is exactly one Office per Area, so that tier is
+the card's own.
+
+Verified by replaying the reported save (`playtests/station-master-seed947338225-day5(1).json`)
+through `fromSave` and printing the panel. Worth noting for anyone who tries it: that save is a
+v0.4.9-line recording and stops at intent 250 of 323 on the 0.7 engine, because Gitea#4, #6 and #7
+changed the rules its later intents were recorded against. That is expected divergence, not a
+save-format bug — a replay reproduces a game from decisions, and the decisions no longer mean the
+same thing.

+    tests: a two-seat competitive game (one human client, one bot) was dealt over the HTTP API with
+    `days: 1`, played to the end of its timetable, and reached `awaitingExtension` on Day 2 with
+    `official = { win, winner 0, daysElapsed }` frozen at Day 1 (`config.days`) and votes
+    `[null, null]`. Voting yes as seat 0 was accepted, the bot followed as designed, and the game
+    returned to `active` with `extraDays: 1` and the official outcome **unchanged**. The tally rode
+    the Frame to the client. Both test games were deleted afterwards; the box is back to Jesse's own
+    `WHISTLE-4086` and the `FREIGHT-3230` lobby.
+
+    **The save carry-over claim was also checked rather than asserted**: phoenix held five saves
+    before the update, of which `WHISTLE-4086` resumed and three were already refused by the 0.7.2
+    deck change. After updating to 0.7.3 the log is identical — same game resumed with the same 7
+    intents, same three refusals at the same move with the same code.
+
+    **What is still untested is the part the item is named for: humans, at a table.** Nobody has sat
+    down and played a game off the end of its timetable, and the multiplayer vote has never been
+    driven through two browsers — what a second player sees while waiting on a first, and whether
+    "waiting on Carol" is legible once Carol has closed her laptop, are still unanswered. Worth being
+    the first thing the next play session does.

+    is wrong, and was found only by reading `advance.ts` while building the tally: the event fires
+    for a train whose profile sets `stopEarnsPoint` — the X18 Circus and nothing else — and
+    `tray.stopPointClaimed` guarantees it fires at most once per train per game. A streak folded from
+    it reads "1 Stage" for ever, which is what v0.7.3 built and then removed.
+    **What it would take:** either a new event emitted per Stage per stationary tray (cheap to emit,
+    but it is a lot of events for a statistic nothing scores), or sampling live state on the Stage
+    boundary the way `stats.ts`'s funnel probe does — which the tally cannot do today, because it
+    folds a batch of events AFTER `advance` has already mutated past the moment they describe. Worth
+    settling with the badge pass (#33) rather than on its own, since that is the only consumer.

+    release notes in all five locales, `README.md` and `instructions.md` updated. No new version file
+    and no migration — the outgoing `0.7.2:0`'s `up` was empty, `versions.md`'s common case, so
+    `current.ts` bumped in place. Verified: `npm run check` clean, prettier clean, `make x86` packs
+    as `v0.7.3:0`. **NOT installed on a box and not played** — see #35.
+
+    **Unlike 0.7.2, games in progress survive this one**, and both docs lead with it. No card data
+    changed and the engine changes are additive, so every intent in a 0.7.2 save is still legal;
+    proven rather than assumed by `test/harness.test.ts`, which replays the three files in
+    `public/replays` (all recorded under an older ruleset) and asserts every intent still applies.
+
+    **Bumped again to `0.7.4:0` the same day** (`085b88b`), pinned to `v0.7.4`, and installed on
+    `phoenix.local` — verified there, not merely packed: the resume log shows `WHISTLE-4086` coming
+    back with its 7 intents and all five new engine code paths present in the served build. Both tags
+    are signed and pushed.
+
+    **Keep doing the whole sequence.** Tag the app, fetch the tag into the wrapper's submodule,
+    bump `current.ts` in place (the outgoing `up` has been empty every time, `versions.md`'s common
+    case), rewrite the notes in all five locales, update `README.md` and `instructions.md`, then
+    `npm run check` / prettier / `make x86` / `make install`. `UPDATING.md` in the wrapper is the
+    authority and has not needed changing.
+
+38. ~~**Gitea#13, #5 and #19 — three rules corrections.**~~ — done 2026-08-29 in v0.7.4
+    (`5e34c73`, `2280276`, `19a6a47`), wrapper `085b88b` as `0.7.4:0`, installed on `phoenix.local`.
+    Each issue carries a comment naming its commit and what was ruled, per #30. Reasoning is in
+    `CHANGELOG.md`; what matters here is what they left behind, below.
+
+39. **NONE OF v0.7.4 HAS BEEN PLAYED BY A HUMAN.** The Yard Office offer, the Red Flag hold and its
+    out-of-phase prompt, and the loaded-Extra make-up rules are all tested end to end, packed, and
+    running on `phoenix.local` — and no person has met any of them at a board. Two are interruptions
+    that stop the Mainline Phase and put a question in front of somebody mid-thought, which is
+    exactly the kind of thing only play reveals. Together with #35 this is now the biggest gap in the
+    project: four features shipped without a table.
+
+40. **A save from before v0.7.4 may not replay, and nobody has been told.** The same shape as #32 but
+    for the main line: the Red Flags intent changed shape, a make-up that was legal may now be
+    refused, and a Yard Office arrival asks a question no older history has an answer for. It fails
+    safe — the server declines the save, names the move and leaves the file untouched — and
+    `WHISTLE-4086` did survive on `phoenix.local`, so it is "may not" rather than "will not". Worth a
+    line wherever the build is announced, and worth knowing when a bug report arrives with a save
+    that will not load.
+
+41. **The bot cannot use the half of Red Flags a human would.** It takes the danger prompt
+    unconditionally and still plays zero flags in 200 games, because the prompt needs a colliding
+    arrival to coincide with holding the card. What it never does is plant a flag ON PURPOSE to buy a
+    Stage for switching, which needs it to know it wants time — a notion it does not have. Reasoning
+    and the measurement are under Bot Performance.
+
+42. ~~**Solitaire must ask before it deals, the same way multiplayer's lobby already does.**~~ — done
+    2026-08-29 in v0.7.5. Jesse: "let the user choose their options like the start of a multiplayer
+    game"; "asking first is the only path." A new `#solitairesetup` screen in `play.html` asks the
+    full shared block — game type, starting hand, Extra start, revenue, victory conditions, optional
+    rules — before a genuinely fresh visit deals anything; a saved game, an explicit `?seed=`, or a
+    URL a Deal already wrote all skip past it. The in-game dialog, the lobby and this screen now
+    share one `wireGameTypeBlock()`/`commitNewGame()` pair instead of the dialog carrying its own
+    copy. Reasoning in `CHANGELOG.md`. **Committed but not yet played in a browser** — verified by
+    `tsc --noEmit` and the full suite (859 pass), not by loading the page and clicking through it.
+    Worth being an early item in the next play session, alongside #39's four unplayed v0.7.4 features.

+- [ ] **FIVE TEST FIXTURES PINNED A SEED AND MEANT "A GAME LIKE THIS".** All five broke on Gitea#14
+      and none of them was about card counts — the deck's SIZE moves the RNG stream, so changing it
+      re-deals every fixture that names a seed. Fixed in place: `mainline-cards` now searches for a
+      Division holding a single-track card, `multiplayer` for a game that reaches Day 3, `web` clicks
+      every play verb rather than assuming the first one goes on the board, and the two `sim`
+      commodity samples were re-measured (tank is first set out at game **216** now, unload Revenue
+      at game **46**). The `web` fix is on BOTH lines — it broke on `main` at the next count change,
+      exactly as predicted. `multiplayer`'s seed search is still playtest-only; port it when
+      convenient.
+
+      A sixth turned up when the dropped cards went to zero: `mainline-cards`' `hand()` helper threw
+      if the card it wanted was not in the deck, so zeroing Flying Switch took five passing tests of
+      an UNCHANGED rule down with it. It mints a card that is no longer dealt now — which is the
+      point of keeping a row at zero, and the same will hold for the ladder if anyone tests it.
+
+- [ ] **THE 0.4.9 PLAYTEST LINE IS BEHIND ON A RULES RULING, and that was checked rather than
+      assumed.** Recorded 2026-08-23, when Jesse asked whether any of v0.7.0 needed porting to the
+      `playtest` branch. Almost none of it does — that line has no lobby and no server, and the
+      `undo()` config fix is inert there because its `GameConfig` carries no victory dials, so
+      `configWith` only ever varies the house rules the save already restores.
+
+      **But one v0.5.0 ruling is a CODE difference the testers do not have.** §A.4, the Local's
+      coach — so on that build a coach still may not be set out at the Office.
+
+      **IT IS THREE SITES, NOT ONE.** This entry named only the first until 2026-08-25, when a full
+      branch diff found the other two. Porting just the `apply.ts` line would leave the build in a
+      WORSE state than either line is in today: the coach could be set out at the Office and the next
+      arriving train would then collide with it.
+
+      1. `src/engine/apply.ts` — `main` reads `if (dropRules.coachStaysOnStationTrack &&
+         cut.some(coach) && !atOffice)`; `playtest`'s is the same line **without `&& !atOffice`**.
+         This is the one that refuses the drop.
+      2. `src/engine/track.ts` — `canDropCarsAt(area, coord, count, coachesOnly)` takes a fourth
+         `coachesOnly` parameter on `main` and returns the Office square as droppable when it is set.
+         `playtest`'s signature has no such parameter and returns `false` for the Office outright.
+      3. `src/engine/advance.ts` — the §8.3 "cars fouling the Running Track" check. `main` reads
+         `officeCard.standing.some((c) => c.type !== 'coach')`, so a coach parked at the Office is
+         not a hazard to the next arrival; `playtest` reads `officeCard.standing.length > 0`, which
+         collides with anything standing there. **This one is behavioural and easy to miss** — it is
+         in a different file from the drop rules and reads as a collision fix rather than a coach one.
+
+      The other two questions the 0.4.9 README calls open are documentation-only there (Poling is
+      already at 0 copies; Heavy Grade behaves identically — both lines run the same
+      `rng.nextInt(2)`, re-verified 2026-08-25 — and it even deals the Mainline deck without
+      replacement, so the correction applies word for word).
+
+      **Jesse's call, 2026-08-23: do not port it now.** A settled rules change is not a playtest bug
+      fix, and pushing one into the build people are mid-playtest on would invalidate the feedback
+      that build exists to collect. Recorded so the divergence is a decision rather than a surprise —
+      and so the 0.4.9 README is not "corrected" to match `main`'s wording, which would then describe
+      behaviour that build does not have.

+- **Gitea#15 — a rail may stop dead against its neighbour, and the rule is on MOVEMENT.**
+  Filed 2026-08-25 as "track placements must connect": a right-hand curve had been laid with its
+  north leg against an Ice House and the turnout below pointing at its portless south edge, and the
+  report called that illegal. **RAR reversed it on review (2026-08-26)** — the placement is fine, and
+  a stub like that has a use, as a siding to park cars on. What he asked to confirm instead is that
+  no train can traverse the gap.
+
+  It could not, and cannot: `exploreMoves` gates every hop on `joins`, which tests both ports AND
+  that two 45° legs lie on the same diagonal — never a bare pair of `hasPort` calls. That was already
+  true; `track.test.ts` now pins it against the reported geometry, including the check that the curve
+  IS reachable from the side that joins, so the negative test cannot pass on a card that is merely
+  unreachable.
+
+  **A per-edge placement check was written and then taken out**, along with the matching guard on
+  `checkTurnoutUpgrade`. Both are documented in place as deliberately absent, because this is exactly
+  the rule someone will "fix" again. `canPlaceAt` keeps only the weaker requirement it always had:
+  the piece must touch the network somewhere, which is what stops orphaned track.

+  games sit where a neighbour's rail points at them, and that is simply legal.

+- **The Uncontrolled Siding and the Interchange print a back region** that is not part of the road. A

+- **ABS holds a train off the card** rather than letting it collide, on any Mainline card.

-may keep the card in their hand for multiple stages and even multiple days, but they may not discard
-it. If a player has three train cards in their hand, and they draw a fourth, then they must play one

+
+**Gitea#9, 2026-08-24 — the ruling in force:** "Timetabled trains are at the choice of the player:
+they can either play or discard. If someone else wants to pick it up, they are more than able to.
+The reason: I don't want, if you decide to play a game longer than five days, to decide that maybe
+there are too many trains, the stations are jammed, and the railroad doesn't need any more. You can
+toss it. Someone else might disagree and pick it up."
+
+So the rule is now:
+
+- a **Timetabled** train may be discarded;
+- an **Extra** may not. It never joins the timetable, so it can never be what jams it, and the only

+
+**"Someone else might disagree and pick it up" needed no machinery.** A discard already goes face-up

  *
- * Players always start at a Whistle Post, which has ONE A/D track, so a second arrival is an

- * a Depot and never escaped: they averaged **−6.0** revenue against **−0.4** for games that
- * upgraded at least once, and 25 of 26 collisions happened at Whistle Post.
+ * THE Q12 DOUBLING IS GONE (Gitea#14). Every tier used to be dealt at twice the sheet, to remove a
+ * 25% chance of an unwinnable opening deal: players always start at a Whistle Post, which has ONE
+ * A/D track, so a second arrival is an automatic collision (§8.3, Gap 2a), and measured at the
+ * sheet's density 25 of 100 games never drew a Depot and never escaped — averaging **−6.0** revenue
+ * against **−0.4** for games that upgraded at least once, with 25 of 26 collisions at a Whistle
+ * Post.
+ *
+ * That measurement was taken against a deck with 96 track cards in it, and the failure it describes
+ * does not survive the halving of track. RE-MEASURED at the sheet's counts, 100 games: **43 of 100**
+ * never upgrade off a Whistle Post, up from 25 — but they average **−0.2** revenue against **+1.4**
+ * for games that do upgrade, where the gap used to be −6.0 against −0.4. Collisions fell from 26 per
+ * 100 games to **6**, and only 3 of those are in games that never upgraded, against 25 of 26 before.
+ *
+ * So staying at a Whistle Post is now common and survivable rather than rare and fatal, which is the
+ * opposite of the shape Q12 was answering: with fewer trains reaching an Office, a single A/D track
+ * is seldom contested. The doubling was the blunt instrument its own note called it, and at the
+ * sheet's deck size it costs more than it buys — see `TRACK_CARDS` for the whole comparison and
+ * `INDUSTRY_PROFILES` for the other half of the same decision.
  *
  * Upgrades are strictly sequential (Gap 3b, no skipping), so Station and Terminal are rarer than
- * their raw counts imply — Terminal needs all three cards in order. Station and Terminal were
- * doubled with Depot to keep that ladder in proportion rather than making Depot a special case.
+ * their raw counts imply — Terminal needs all three cards in order.
  *
- * PROVISIONAL — re-evaluate. This was chosen to remove a 25% chance of an unwinnable opening deal,
- * not from the recovered design, and it is a blunt instrument: it lifts the whole office ladder and
- * dilutes every other category slightly. Revisit once the victory target is settled and freight is
- * carrying its intended share; the right answer may instead be fewer Terminals, a cheaper first
- * upgrade, or more A/D capacity at Whistle Post. The counts themselves are in the rows below, which
- * is the only place they should be read from.
+ * IF THE OPENING BITES AGAIN, the fix is not to re-double this. The note it replaces already listed

-/**
- * WHICH WAY THE GRADE CLIMBS, AND WHY NO PLAYER CHOOSES IT.
- *
- * Q11, answered from the card: Heavy Grade prints "(Up)" and "Player sets orientation", so the climb
- * is a property of the PLACED CARD rather than a compass constant. `gradeUp` is the direction a train
- * is travelling when it goes UPHILL; a train heading the other way is descending.
- *
- * **The second half of that print is deliberately overridden.** No player sets it — `setup.ts` rolls
- * it from the seed. Settled v0.5.0 and re-confirmed 2026-08-23 after the question was raised again:
- * a Heavy Grade always sits BETWEEN two districts (or beyond an end Division Point next to one),
- * never inside one player's own, so there is no player with a fair claim to the choice — and the
- * choice is not cosmetic, because it decides which of the three modifiers below can ever pay and
- * therefore which direction of traffic is favoured, permanently. Giving it to the Superintendent was
- * considered and rejected in that re-examination: the office rotates every three Stages, the
- * advantage does not. Full reasoning in implications.md §10 Q11.
- *
- * Each applicable card takes a Stage off, never below one: a train cannot cross in no time.
- * Airbrakes only counts when Brakeman is already there, which the placement rule enforces
- * (`MAINLINE_MODIFIER_RULES`, `requiresOnCard`).

+ *      identically every time — which is what makes Undo and a server restart correct here for free.
+ *   3. The official result freezes a COPY of this at the moment the timetable ran out (`official`

+ * The event tally — Gitea#16's statistics, folded from the event stream into `GameState.tally`.
+ *
+ * WHERE IT IS HOOKED, and why it is not in `reduce`. `apply.ts`'s `reduce` sees only the events an
+ * INTENT produced; `advance.ts` mutates state directly and pushes its events without reducing them
+ * at all — and `advance` is where `trainCompleted`, `trainsDestroyed` and `trainStoodStill` come
+ * from, which are exactly the numbers this issue asks for. So the fold is hooked at the two places
+ * every event in the game passes through exactly once on its way to a caller:
+ *
+ *   - `applyIntent` (`apply.ts`), beside its `reduce` loop;
+ *   - `advance` (`advance.ts`), which now wraps the phase driver and folds what it returns.
+ *
+ * Exactly once matters in both directions: an event folded twice inflates a count, and an event
+ * folded nowhere is a statistic that silently reads zero. `test/tally.test.ts` pins both by playing
+ * real games and checking the tally against an independent count over the same event array.
+ *
+ * NOTHING HERE IS A RULE. The tally is read by the results screen and by the badge work Gitea#16
+ * leaves to a second pass; no engine decision consults it. That is what makes adding a counter
+ * always safe.
+ *
+ * WHAT IS NOT COUNTED PER PLAYER, and why. `carsCoupled` and `carsDropped` carry a `trayId` and no
+ * `player` — switching is done BY a crew, and the event says which crew rather than which person.
+ * Rather than guess an owner from whose turn it happened to be, those two are table totals only.
+ * The events that do name a player (`loadCompleted`, `passengersBoarded`, `cardPlayed`,

+/**
+ * §3.3, EXTENDED PLAY — Gitea#11, "when game ends allow players to continue playing if they wish".
+ *
+ * The rule as Jesse specified it (2026-08-28), which is what these tests are written against:
+ *
+ *   - the OFFICIAL result is decided at the original game length and never changes. "In a five-day
+ *     game, even if it's extended to eight or nine days, the winner and the official answer is the
+ *     winner at the end of five days";
+ *   - extending grants exactly ONE Day, and the question is put again at the end of it;
+ *   - solitaire: the player decides alone. Multiplayer: unanimous, and one refusal ends it there;
+ *   - only days-based endings offer it. A §3.4 collision breach is final, during an extended Day
+ *     just as during the regular game.
+ *
+ * The persistence half matters as much as the rules half: a save is `{ seed, config, history }`
+ * replayed through the engine, so an extension that is not an INTENT does not survive a reload, an
+ * Undo, or a server restart. `replays the extension` below is the test that pins that.
