TODO.md: work sections first, the argument moved to the back

The file had reached 2,441 lines and had to be read end to end to find
out what was live. Restructured with Jesse.

WHAT WAS WRONG was not the ordering. Eight subject sections sat under a
43-entry chronological queue that had come to duplicate them: the queue
was where the priority lived, the sections were where the reasoning
lived, so every live item existed in both and drifted between them.
That is what let eight items be closed in one place and left open in
the other last week, which reads as live work and is worse than no
entry at all. One item per place now.

THE SHAPE. A short overview; then "Every time", the process this
project runs on — the version bump being Jesse's call, signed commits
and tags, deploying from the right line, the wrapper release sequence,
and the lesson that only a test failing before the fix proves a fix;
then an index; then ten work sections in priority order, one per area,
each holding every open item for that area. Play it at a table first,
because the file itself calls it the largest gap in the project.
Gitea#20 second, as v0.8.0. Then multiplayer operations, the screen,
replays, rules, balance, the bot, code health, documentation.

THE ARGUMENT MOVED TO THE BACK, NOT AWAY. An item in a work section is
a few lines: what it is, what it blocks, what it would cost. The
measurements, rulings and rejected approaches behind it are in a
Reference section keyed by the same number, moved verbatim. All 61 open
items have one. Then Done, which keeps every closed item because
several are the only record of a ruling or a lesson.

Checked mechanically rather than trusted: every lead and every body
line over 40 characters from all 120 items of the old file was
asserted present in the new one. Zero fragments lost. Two rendering
bugs the move introduced were caught the same way — bodies that were
list continuations indented 4 or 6 spaces render as CODE BLOCKS once
they are no longer inside a list, and a wrapped lead splits mid
sentence if a blank line is inserted before its continuation.

THE NUMBERS ARE PERMANENT IDS. Items keep the number they were raised
under for life, wherever they later move, because commit messages,
Gitea comments and other items refer to them by number. Nothing was
renumbered; previously unnumbered items took the next free numbers.
Items that existed only as queue entries — 32, 33, 35, 36, 39, 40, 42a
— are proper items with checkboxes for the first time, which is why the
open count reads 61 against last week's 54 without anything new being
raised.

Also carries the two items Jesse asked for while finishing 0.7.9. #44:
how much history the panel holds should be configurable, with his three
candidates left deliberately open — a StartOS action reaches only
multiplayer, since solitaire has no server; per game puts a display
preference into the ruleset and every save; per browser is where every
other display preference already lives. The cap has no recorded reason
anywhere, and the replay viewer already answers the same question in a
different unit. #46: 29 unused declarations and no flag to catch them,
with the argument that the flag matters more than the 29.

+## 0.7.9 — 2026-08-30
+
+Four pieces of feedback on the solitaire setup screen, plus the rules bug the second one exposed.
+
+### The collision limits were dead settings in solitaire — now they are not
+
+Asked to reword the collision entries to "the game ends immediately and results in a loss", which
+turned out to be unwriteable: `advance.ts` gated the whole §3.4 check on
+`mode === 'competitive' || mode === 'coop'`, and a solitaire game's mode is `'solitaire'`. So both
+limits were offered on the New Game dialog as live settings, rode into the config, and never fired.
+A solitaire player could set a limit of 1 and crash all game. The *existing* text beside them ("the
+game ends in a loss") was already false; the new wording would only have made it more so.
+
+The exclusion was never a stated rule — §3.4 does not carve solitaire out — and nothing recorded a
+reason for it. **Jesse's ruling: the settings do what they say**, so the mode gate is gone rather
+than the controls.
+
+**A solitaire game can therefore now end early, and that is measured rather than asserted.** Over
+200 standard games with the developer bot: `loss/collisionFloor` **1 game in 200**, with Days played
+falling 5.00 → 4.98 mean and a *minimum of 1* — a bad opening Day can now end a game outright.
+Collisions per game are unchanged (0.14 mean, max 3), which is the point: the ending is rare because
+crashes are, not because the check is lenient. `0` still switches either limit off, at one seat
+exactly as at four, and that path has its own test now.
+
+Every figure in `TODO.md` quoted from a full-length solitaire run predates this.
+
+### Where an Extra may start defaults to your own Control Point
+
+Was "any player's". At one seat the two are the *same rule* — `apply.ts` only rejects `ownOffice`
+when `start.seat !== seatOf(s, player)`, which cannot happen — so this is a labelling fix with no
+gameplay effect and nothing to re-measure. The permissive label described a permission a lone player
+was never being granted, and named an "any player" they have no contrast with.
+
+### The extension question was hidden behind the results screen
+
+Jesse, 2026-08-30: "Solitaire game ended. I did not have an option to extend the game by a day."
+
+**The engine and the Frame were right the whole time** — checked before changing anything: a
+solitaire game at the end of its timetable reaches `awaitingExtension` with `extensionVotes: [null]`,
+and `isExtendable` covers both `revenueFloor` and `daysElapsed`. `renderActions` reaches
+`renderEnding` for any non-active status, and `renderEnding` writes "play one more Day" and "end the
+game here" into `#actions`.
+
+Then it opens `#resultsdlg`, **which is modal**. So the two buttons were rendered directly underneath
+a dialog whose only control was Close, and the player read a results screen that offered nothing but
+Close and concluded the game was over — which is precisely what it looked like.
+
+The results dialog now carries the question itself, hidden unless a vote is actually pending:
+**Play One More Day** and **End the Game Here**, casting the same `game.extend` intent. The
+`#actions` buttons stay, because they are what remains once the dialog is closed and what a player
+who reopens it with "see the full results" comes back to.
+
+**Why this survived being "verified".** `TODO.md` #35 recorded extended play as checked on
+`phoenix.local` — over the HTTP API, which renders no dialog. The browser path had never been run to
+the end of a timetable. Same shape as the three attempts before it: the thing that was verified was
+not the thing the player uses.
+
+### `configWith` let the day count and the Revenue floor disagree
+
+`minCombinedRevenue` fell back to `SOLO_CONFIG`'s constant — the floor for a *five*-Day game —
+whatever `days` said. So `configWith({ days: 1 })` asked a one-Day game to clear **15**, a figure a
+full five-Day game averages barely half of, and `configWith({ days: 10 })` asked for the same 15 a
+five-Day game does. It derives from the days it was actually given now.
+
+Not a live fault: `createLocalSession` is the only caller, and the page always writes the floor
+itself, so no dealt game was ever wrong. It was found by a throwaway probe written to reproduce the
+extension bug above, which passed only `days` — which is exactly how the next caller would reach for
+it. At the default day count the answer is unchanged, since `SOLO_CONFIG`'s own floor is this same
+formula at `DEFAULT_DAYS`; the three new tests pin that as well as the derivation.
+
+### A Heavy Grade shows which way it climbs
+
+Jesse, 2026-08-30: "heavy grade mainline card tooltip states climbs east, but card doesn't show it."
+The Frame has carried `gradeUp` since the Division map was rebuilt and the tip has read "climbs
+east" all along — but the one Mainline card whose orientation is set per game, and the one where
+Helpers and Brakeman mean opposite things at opposite ends, drew nothing to tell the two apart.
+
+A brown wedge in the card's lower right, rising toward the climb, with a bone arrow lying along its
+slope. **East is right on this map** (Gitea#18), which is what lets a wedge be read without a
+compass — and is the layout decision paying for itself again.
+
+**Four passes, and the first three are worth recording because each failed differently.** An arrow
+up the hypotenuse had to start at the wedge's thin corner, where there is no height to draw in, so
+its head sat over the edge and read as clipped. Level, it was contained but did not read as
+climbing. At 30° — steeper than the wedge's own 22.5° — it had to be tucked into the fat half to
+survive. Lying **along** the slope is the shape that fits: the perpendicular gap to the hypotenuse
+is then constant down the whole arrow instead of closing at one end, so it can sit on the triangle's
+centroid. The wedge grew 44×19 → 58×24 to pay for that, because a centred arrow has *less* room than
+an off-centre one — the centroid is about 7px from the hypotenuse.
+
+The final sizes are a search result rather than an eyeballed nudge: the roomiest arrow keeping all
+seven vertices clear of both edges, at 2.88px.
+
+**A test that passed a visibly broken glyph is the reason this is pinned properly.** The first
+containment check bounded the arrow against the CARD, which it never left — while the wedge clipped
+it. The check is against the *triangle* now, with a 2px floor, plus the arrow being parallel to the
+wedge (derived from the wedge, so resizing it cannot leave a stale angle) and centred on the
+centroid.
+
+**Orientation is always set — measured, not assumed**, since a wedge that invented a direction would
+be worse than no wedge. Across 400 seeds × 4 player counts: **535 Heavy Grades placed, 0 without an
+orientation**, 276 east / 259 west. `setup.ts` is the only place a Mainline node is created and it
+rolls the direction from the seed for every grade, so the `?? 'east'` fallbacks in `view.ts` and
+`advance.ts` are unreachable.
+
+### Two setup screens, not three — the in-game dialog is deleted
+
+Jesse, 2026-08-30: "If you are in the Solitaire game and you click the new game dialog, it should not
+go to a separate screen. We should reuse the Solitaire New Game Screen… in general we should reuse
+what we already have."
+
+`#newgamedlg` was a third copy of the same questions and the one that drifted. It was shown ONLY to
+a solitaire player, and it asked "Everyone loses if **combined** Revenue at the end is under" — a
+table's question, put to one person — and explained Employee Rotation in full, in multiplayer terms,
+beside a control it had itself disabled. Both were on the list to re-word. Deleting the screen
+removes the drift instead of restating it, which is the cheaper fix and the one that cannot drift
+again.
+
+**New game now opens the setup screen in place.** Not a navigation: the live session stays in memory,
+so the fields open on the rules actually being played — which is what the dialog was good for, and
+losing "change one dial, redeal, compare" would have been a real loss — and **Continue Existing Saved
+Game** puts the board straight back with no reload and no replay. Nothing is at risk either way:
+`render()` calls `save()` every frame, so the game in progress is always on disk.
+
+**And the two remaining screens now match below their headers.** Each keeps its own opening — the
+lobby's join/secret section and "Create a new game" are multiplayer's alone — but from the parameters
+down they are one form: the same three fields in the same order (seed, players at the table, days),
+the same note about a seed and settings dealing the same railroad, and the same note about every
+chair being taken. Solitaire shows **Players at the table** too, locked at one, rather than omitting
+it — a control that is present and fixed says "this is the same form, at a table of one", where a
+missing one just made it a different form that happened to share a rules block.
+
+The drift guard that had been checking three prefixes now checks two, and a new assertion fails if
+any `ng-` id ever reappears.
+
+### The two screens are worded the same, section by section
+
+Jesse, 2026-08-30: "let's get the text between the Multiplayer and solitaire as close as possible to
+the same." Walked section by section; where the two said the same thing differently, the lobby's
+wording won, because it was written for the harder case.
+
+- **The chair note is one paragraph on both**, replacing two that each described only their own
+  case: "Every chair must be filled before the game can start. For solitaire, there's only one
+  player. For multiplayer, that must be filled by a person or a bot. The number of players cannot be
+  changed once the game is created."
+- **The Game type heading names which game the screen deals** — "Game type (multi-player)" and
+  "Game type (solitaire)". That heading is now the whole explanation for the dimmed rows.
+- **No reason is printed beside a dimmed type any more.** The lobby appended "— dealt with the New
+  game button, not here" to Solitaire, and the solitaire screen appended "— use the Multiplayer
+  button; a table needs a server" to each of three. Jesse: "grayed out with no additional
+  explanation. The explanation above… is sufficient." One heading says it once; three rows were
+  saying it three times. `markUnavailable` is down to dimming, and `.lb-why` is gone with them.
+- **The sentence under the radios is deleted on both.** It restated the type just chosen to the
+  person who had just chosen it. Its one non-obvious case — how many settings a Custom game differs
+  by — is not lost: `form.mark` already puts "Co-op default: …" on each row that differs, which is
+  where a reader can act on it rather than a count they would have to go and find. The tests that
+  read that sentence now read the row hints instead.
+- **The Game settings, Starting hand and Victory conditions notes are the lobby's on both**, with
+  one edit Jesse asked for: "clicking a type again resets" → "changing the game type resets", which
+  names the control that does it rather than a gesture. Victory conditions was not on his list —
+  applied under the same rule, and the lobby's wording fits now that solitaire also shows the table
+  size.
+
+What is deliberately still different: each screen's own opening paragraph, and the heading above.
+
+### The status line said nobody was holding the game up
+
+Jesse, 2026-08-30: "waiting on shows 'nobody — the Division is running itself' BUT the system is
+actually waiting on the Superintendent."
+
+`Frame.actor` carried `clock.currentActor`, which is null for the whole Mainline Phase — so the three
+interruptions that stop the game and put a question to a named person (§8.1's clearance ruling,
+Gitea#5's Yard Office offer, Gitea#19's Red Flag prompt) all reported that the Division was running
+itself. `actingPlayer` has had the answer since the Gitea#5 refactor; the Frame threw it away.
+
+It carries `actingPlayer` now, **and what the question is**: "waiting on **Bob** · a clearance ruling
+· Train 4". Naming the person is not enough on its own — three different things can be pending, and
+"waiting on Bob" with nothing after it is a game that looks stuck to everyone except Bob.
+
+### The Fedora moved to the end of the phase row
+
+`TODO.md` #29. It sat on a line of its own between the phase chips and everything above them, which
+put a thing that moves every third Stage in among the things that move every Stage. It rides at the
+right-hand end of the phase row now — the row whose last chip is Supervisor Shift, the phase that
+passes it — and wraps underneath rather than squeezing the chips on a narrow screen.
+
+### The developer replay stopped printing a raw enum
+
+`TODO.md` #34. Its heading read `loss — revenueFloor`: the exact defect Gitea#16 was filed about on
+the playable page, still alive here a release after that was fixed, because nothing player-facing
+pointed at it. It reads "lost — The Division closed short: 3 Revenue between everyone, against a
+floor of 15…" now.
+
+`panels.ts`'s `reasonSentence` is exported and shared rather than reimplemented, so the replay and
+the results screen cannot explain one ending two different ways. It is fed the last recorded frame —
+the state the outcome was decided in — and stripped of markup, since it lands in an `<h1>` and a
+console line. The drift test that compared this string against the engine now maps `win`/`loss` to
+`won`/`lost`, so it still checks the two agree rather than that they are spelled alike.
+
+### The save warning, the buttons, and a claim that was simply false
+
+Three more from Jesse reading the two screens side by side.
+
+- **The save warning is a warning.** "That's a warning, not an 'oh by the way'." It had already moved
+  off `.ng-note` earlier in this release; it is larger and heavier again now — 15px, weight 500,
+  bright amber on a deeper ground with a 5px rule down the side. Worth noting what he was actually
+  looking at: `phoenix.local` runs v0.7.8, where this line is still the small grey `.ng-note`. None
+  of this release has been deployed.
+- **The buttons read the same on both screens**: **Continue saved game** and **Create new game**.
+  Solitaire said "Continue Existing Saved Game" and "Deal New Game"; the lobby said "Create game".
+  Three phrasings for two actions.
+- **"Off in every game type" is deleted from the Optional rules note, because it was not true.**
+  Checked against the presets rather than taken on trust: `discardTimetabled` — §6.2's "a Timetabled
+  train may be discarded" — ships **on** in all four types, not just Co-op. The note now says only
+  what is true of all of them: "Each one changes how the game plays."
+
+### A game you come back to has not begun
+
+Jesse, 2026-08-30: "when you are continuing the saved game out of that screen, do not post a message
+that says 'The game has begun.' … it needs to say 'The game has resumed.'"
+
+A restored game draws exactly like a dealt one — mid-Day, mid-phase, with a log already several turns
+deep — and **solitaire said nothing at all** to tell them apart. It flashes "The game has resumed —
+Day 3, Stage 7" now, on both ways back: the setup screen's **Continue saved game**, and a bare reload
+that restores the save.
+
+**The same line was wrong on the multiplayer side, in the other direction.** `noteFirstFrame` guards
+on `firstFrameSeen`, which is per page-load — so re-entering a game this browser already held a seat
+in, by reloading mid-game or picking it out of the lobby's list, announced that the game had **begun**
+to somebody who had been playing it for an hour. `beginRemote` carries whether this is a rejoin now,
+and the line reads "resumed" when it is.
+
+Both halves are pinned, including that a brand-new game does *not* claim to be a resume — an
+announcement that fires either way says nothing.
+
+### The screen does what you tell it — three items off `TODO.md`
+
+Reviewed with Jesse 2026-08-30 out of the Display section. A fourth, #17 (hiding the Division map),
+was **declined** in the same pass: its premise died with Gitea#18 and nobody had connected the two.
+The map used to grow a row at a time and was worth folding away at three or four seats; a single row
+is `boardH = PAD * 2 + CH + 30` — 150px, fixed, at every seat count — and that is not worth a
+control, three states and a persisted preference.
+
+#### The Office Area's auto-hide could not reach every state (#16)
+
+One button cycling `auto -> pinned -> auto`, where the pin it reached was
+`open ? 'closed' : 'open'` — and `open` is what auto is doing **at that moment**,
+`FOCUS_PHASES.has(f.phaseKey)`. So which pin a press offered depended on the phase: "always hidden"
+during Local Operations and Cargo, "always showing" everywhere else. Getting from one pin to the
+other meant clicking back to auto, waiting for the phase to turn over, and clicking again. That is
+why it never read as a setting — it was not one.
+
+Three controls now, one per mode, and every mode is one press from every other. The labels still say
+what pressing **does** rather than what the panel is doing, which was an earlier deliberate fix; what
+the cycle could not do was report the state it was in, and `aria-pressed` on the lit button carries
+that instead of the label.
+
+**Addressed by id (`#dm-auto`/`#dm-open`/`#dm-closed`) rather than by querying the container's
+children**, and that is a testability decision rather than a style one. The page never writes this
+markup, so a child query finds nothing in the stubbed DOM the web suite runs against — the control
+would have shipped green and completely unexercised. The test that now pins it presses
+always-show → always-hide directly, which is precisely the transition the cycle could not make.
+
+#### The history reads newest first (#23)
+
+Jesse: "it should be reversed so the top line is the most recent and the further down you go, the
+older the entry." The panel ran oldest-first and scrolled itself to the bottom, so the thing that had
+just happened was the one line you had to go and find.
+
+**The phase headings now trail their lines, and that is accepted rather than overlooked.** A
+`t-phase` line reads forwards — it introduces what follows it — so reversing puts each one below the
+events it announced. Jesse ruled on it directly: "stage changes will be beneath (prior to / older
+than) the following events. That is OK." Reading down the panel is reading backwards in time, and a
+heading under its own lines is what backwards looks like. Grouping by phase and reversing the groups
+was the alternative and was declined as more machinery than the complaint needs. The
+"— the game began —" marker moves by the same logic: it is the oldest thing on screen, so it goes
+last.
+
+`replays.ts` keeps its own oldest-first log deliberately. It is paired with a frame stepper, where
+"what just happened" is the step you have this moment clicked, so newest-first would fight the
+stepping rather than help it.
+
+#### The settings moved into a card, and the collision counts came out of hiding (#28)
+
+Jesse, 2026-08-23: "the game-specific information in the very top line should probably be a card like
+Facilities, timetable or blocked… we can give complete information about all the game options and not
+take up valuable real estate at the top of the screen." And on when it is read: "To go, 'Oh wait, what
+did we set that to?'"
+
+The top line carried six things and now carries four: **Revenue, the objective, the collision counts,
+and the game code**. The seed or seat, the game type and the abbreviated house rules moved into a
+**This Game** card at the foot of the right-hand column, folded by default and persisted with the
+other display preferences.
+
+**Nothing new travels for it.** `configFromFrame` already turns the Frame's copy of the config back
+into a `GameConfig`, and `rulesListHtml` is the renderer the lobby's join preview and seating screen
+already draw — so what a player agreed to before the deal and what they read mid-game come from one
+implementation and cannot drift. The card adds only the half `rulesListHtml` has no notion of: which
+seed or seat this is, and what the game is called.
+
+**The collision counts are new on the board, not merely moved.** The Frame has carried
+`collisionsToday` and `collisionsTotal` since v0.7.0 and nothing drew them, so the one victory
+condition that ends a game EARLY ran invisibly — which v0.7.9 made reachable in solitaire too, and
+that is what made them worth having. They stay on the top line while the limits go in the card,
+because the two are different kinds of thing: a limit is a setting agreed to once, "2 of 3 today" is
+a number that changes how you play the next Stage. A limit of `0` is off, and an off half is left out
+rather than shown as "1 of 0"; with both off the chip is empty and collapses.
+
+In solitaire the game-code span is empty, so its tooltip — which still carries the type, the blurb and
+the victory conditions — is unreachable. Not a hole: the card's summary line is on screen whether the
+card is open or shut and opens with the type, "Solitaire · 5 Days · floor 15 · 3 cards · 4/2/1".
+
+**One gap in the test stubs was closed to get here.** None of the five element factories in the web
+suite had `setAttribute`, so the first render threw `b.setAttribute is not a function` — meaning any
+control that reports its state through ARIA could not be tested at all. They carry an attribute bag
+now, and the segmented control's test reads `aria-pressed` through it.
+
+**What is verified and what is not.** The logic is covered by three new tests and the two that used to
+read `#houserules`/`#gametype` were rewritten to open the card rather than deleted. **The layout is
+not verified** — there is no browser on this box, so nothing has confirmed the segmented control, the
+card, or the reversed panel actually look right on screen. That wants a play session.
+
+### Four things the game counted and never said
+
+Prompted by Jesse asking the general question after two separate v0.7.9 fixes turned out to have the
+same shape — `actingPlayer` existed and the Frame threw it away, and `collisionsToday`/`collisionsTotal`
+rode the Frame for three releases with nothing drawing them. So: **what else is being computed,
+serialised and sent to nobody?**
+
+Audited rather than guessed. Every one of `Frame`'s 59 top-level fields grepped for a read across the
+seven renderers, then the same for `Tally`'s 26 members. **55 of 59 are read.** The four that are not:
+
+- **`tally.unloadsBegun`** — and this one was visible rather than merely unused. §9.1 makes loading
+  and unloading the same shape, begun then carried through, and the results screen printed "Loads
+  still in the pipeline" for one side and nothing for the other. It reported half of a symmetric
+  mechanism. There is an "Unloads still in the pipeline" line now.
+- **`tally.cardsDiscarded`** — counted by the engine, listed beside "Cards drawn" and "Cards played"
+  without it. Gitea#9 made throwing a Timetabled train away a legal, deliberate move, so a discard is
+  a player CHOICE the game counted and never reported. It reports it now.
+- **`viewerSeat`** and **`overHandLimit`** — deferred by Jesse. The second is the fullest version of
+  the shape: the engine computes it, `view.ts` puts it on the Frame, `session.ts` declares it on the
+  `Session` interface and implements it twice, and the only caller in the repo is its own test. Four
+  layers of plumbing with no consumer. Left alone for now; the decision when it comes is
+  delete-or-document, not a patch.
+
+**Fixing the two turned up a third thing worth knowing.** `resultsHtml` draws
+`tallyHtml(report?.tally ?? f.tally)`, and `report` is `f.official`, which the engine writes the
+moment any game ends — so a finished game reports the tally frozen at the official ending, not the
+live one. The first attempt at a test overrode `f.tally` alone, changed nothing on screen, and failed
+for a reason that had nothing to do with the fix.
+
+### A shouted keyword is not a sentence
+
+`EXTRA X18 started…`, attributed to a player, rendered as `Player Solitaire eXTRA X18 started…`. The
+same happened to `TRAIN 1 MADE UP` and `COLLISION`, which are shouted deliberately.
+
+`record` folds a narration's opening word into the middle of a sentence — "Chose to draw" has to read
+"Player Bob chose to draw" — and did it with a flat `charAt(0).toLowerCase()`. It now folds **only a
+sentence-cased word**: `^[A-Z][a-z]`, a capital followed by a lower-case letter, which is an ordinary
+word capitalised because it began a sentence and nothing else is. That also leaves `X22 Pee-Dee`
+alone, which a naive "is the first letter uppercase?" test gets wrong, because `'2'.toUpperCase()`
+is `'2'`.
+
+**It had been filed under Play Balance**, where it has no business being — which is how it survived a
+session that had explicitly ruled balance work out of scope. Found by reading the section it did not
+belong to.
+
+### A replayed save now narrates what the live game narrated
+
+`fromSave`'s loop called `record(game, result.events)` with no `actor`, so every restored save, every
+undo (which rebuilds through `fromSave`) and the replay viewer stripped the "Player X" prefix off
+every attributed line. Live play attributes — `submit` passes `actor` — and so does multiplayer's
+replay; this was the one path of the three that did not, which meant the same moves were described in
+different words from the game that produced them. The fix is one argument, with `actor` already
+computed on the line above.
+
+**Why it survived two years of green tests, which is the part worth keeping.** Nothing ever compared a
+`fromSave`-built log against a LIVE-played one. The single log-comparing test compares `undo`'s
+rebuilt log against another `fromSave`-built log — and since `undo` itself rebuilds through
+`fromSave`, the missing attribution cancelled out on both sides. The whole suite stayed green with the
+bug in place, and stayed green after the fix too.
+
+The new test plays a game, saves it, restores it, and asserts the two logs are identical. That is the
+**missing direction**, not a new requirement. All three of this batch's fixes were confirmed to fail
+with the fix reverted before being called done — the discipline the v0.7.5→v0.7.8 sequence bought.
+
+### Three wording and layout fixes
+
+- **The collision entries** on all three screens now read "The game ends immediately and results in
+  a loss…". The Revenue floor keeps its own wording, since it is settled at the end rather than on
+  the spot.
+- **Employee Rotation** on the solitaire screen says "not applicable for solitaire" instead of
+  "meaningless at a table of one, shown here so this screen and the lobby read as one list" — which
+  explained the page's own construction to somebody who had not asked.
+- **The save warning is legible.** It sat in `.ng-note`, the same dim 11px grey as the twenty
+  explanatory notes above it, while being the only thing on the screen describing something
+  irreversible. It is 14px on an amber panel now — amber and not red because losing a save is a real
+  cost, not a danger, and red would outrank the actual rules above it. The buttons say **Continue
+  Existing Saved Game** and **Deal New Game** rather than "Continue saved game" and "Deal".
+
+884 tests pass, seventeen of them new; one existing test asserted the opposite of the collision ruling
+above and says so where it was reversed.

+
+## 0.7.8 — 2026-08-30
+
+### The setup screen was unreachable for anyone who had ever played
+
+Third report of the same symptom, and this time the build was confirmed current on screen
+(`0.7.7-mtf7hyxc`), which ruled out the caching fault v0.7.7 had just fixed and left the actual
+cause with nowhere to hide.
+
+**v0.7.5 skipped the setup screen whenever `load()` found a save**, reasoned in its own comment as
+"a saved game is a game to resume". The consequence went unnoticed: a browser that has ever played
+solitaire *always* has a save, so the door could never reach the screen again. Only a browser that
+had never played would see it — which is exactly why a fresh private window appeared to prove
+v0.7.7's cache fix. The private window had no save. Two genuine faults were stacked, the caching one
+was real and is fixed, and it masked this one.
+
+**The door now outranks a saved game.** `?solitaire` is an explicit request to set a game up;
+clicking "Play solitaire" is not a request to resume. A BARE reload still resumes, which is the
+zero-friction case D11 is about and is pinned by its own test.
+
+**Dealing from the door would have destroyed a game in progress**, since `commitNewGame` calls
+`clearSave()` — so the screen now carries `#ss-resume` ("Continue saved game") and states plainly
+that dealing replaces the save. Resuming navigates to the bare URL rather than building a session
+on the spot, so `start()` stays the only place that turns a URL into a game.
+
+**Recorded because the failure was diagnostic, not technical.** The first two attempts each fixed
+something real that was not this, and both were reported as verified. The routing fix in v0.7.6 was
+verified by reading what the server served; v0.7.7's by the same. Neither ever exercised the actual
+path with the actual state a returning player has. The reproduction here is a failing test asserting
+the door with a save present — written before the fix, and it failed with "a saved game swallowed
+the door".
+
+### The splash footer names both ways to play
+
+Was "solitaire runs entirely in your browser — no server code required", written when solitaire was
+the only door. Now: "Multiplayer runs on StartOS server. Solitaire runs entirely in your browser."
+(Jesse, 2026-08-30, asked to ride along with the next change rather than take a release of its own.)
+
+868 tests pass, four of them new.
+
+---
+
+## 0.7.7 — 2026-08-30
+
+### Two releases shipped to a browser that never received them
+
+Jesse installed v0.7.5, clicked **Play solitaire**, and landed in a dealt game instead of the new
+setup screen. v0.7.6 diagnosed that as a routing bug, fixed it, installed, verified — and it happened
+again, identically. The second report is what made the real cause findable: the fix was correct both
+times and neither one ever reached the browser.
+
+**`buildStamp()`'s no-git fallback was the literal `nogit`, and the `.s9pk` build has no git.** The
+Dockerfile copies the working tree in without `.git`, so `git rev-parse` fails there on every
+packaged build — and that string is not only the visible stamp, it is the cache-bust key every module
+URL carries. So v0.7.4, v0.7.5 and v0.7.6 all published `./web/main.js?v=nogit`, byte-identical, and
+a returning player's browser correctly concluded it had the file already. The fallback is now the
+package version plus the build's own timestamp, which is always distinct and needs nothing from the
+environment. Proven rather than assumed: two builds of an identical git-less tree now stamp
+`0.7.6-mtf6l8rm` and `0.7.6-mtf6lant`.
+
+**And the server sent no `Cache-Control` at all**, which is the other half — the pages are the one
+thing that cannot be versioned in their own URL, since a player types the address or follows a
+bookmark, so a cached `play.html` pins that player to the whole build it names including every `?v=`
+inside it. Fixed the exact way round that matters: a request carrying `?v=` may be stored for a year
+and marked `immutable`, and anything else is `no-cache`. `?v=` rather than "not HTML" because
+`build-web.ts` tags the modules and nothing else — a year of `immutable` on an untagged image or on
+the replay manifest would outlive several releases of it.
+
+Neither half is sufficient alone: without the varying tag there is nothing for a fresh page to point
+at, and without the header the fresh page is itself served from cache.
+
+**What this says about the two releases before it.** v0.7.5's setup screen and v0.7.6's door fix were
+both real, both correct, and both verified on `phoenix.local` by reading what the server served —
+which was true, and was never the thing in doubt. What went unverified was the browser, and a
+hard-reload would have told us on the first report. Worth remembering the next time a fix "has had no
+effect": check that it arrived before re-diagnosing it.
+
+864 tests pass, two of them new — one pinning the no-git fallback as something that varies per build,
+one pinning the header rule and that the `?v=` flag actually reaches `serveStatic`.
+
+---
+
+## 0.7.6 — 2026-08-29
+
+### The solitaire door could not reach solitaire
+
+Found by Jesse verifying v0.7.5 on `phoenix.local`: from a browser that had ever held a multiplayer
+seat, clicking **Play solitaire** on the splash landed straight in a Co-op, four-seat lobby left over
+from unrelated earlier testing — not the new setup screen v0.7.5 just shipped.
+
+`start()` checks a browser-remembered multiplayer session (`station-master.remote.v1`) before it ever
+looks at solitaire's own state, and there was nothing distinguishing "clicked Play solitaire" from
+"reloaded mid multiplayer game" — a bare `./play.html` load means both. `?lobby` already solved the
+identical problem for the door on the other side (D11); the solitaire door had no equivalent marker.
+
+The door now links to `./play.html?solitaire`, and `start()` treats that — along with an explicit
+`?seed=` or a `?hand=` the setup screen's own Deal button just wrote — as unambiguous proof this
+navigation means solitaire, checked ahead of the remembered-session lookup rather than only below it.
+The `hand` check matters on its own: without it, pressing Deal would work once and then bounce the
+very next load into the remembered game, since `commitNewGame`'s URL carries `hand=` but not
+`solitaire=`.
+
+862 tests pass, three of them new: the door reaching solitaire past a remembered game, a bare reload
+still correctly resuming one (unchanged behaviour, pinned so the fix does not overreach), and Deal's
+own URL surviving the same bounce.
+
+---
+
+## 0.7.5 — 2026-08-29
+
+### 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.
+

+ *      (`web/game.ts`'s `fromSave`), so a tally folded from the events that replay emits is rebuilt
+ *      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`

+ * Aggregate counts only. Nothing here is seat-secret — no card ids, no hands — which is why

+     SOLITAIRE SETUP — the same question multiplayer already asks first,
+     now asked here too (Jesse, 2026-08-29): a genuinely fresh visit deals
+     nothing until this screen's own Deal button is pressed. A saved game,
+     an explicit `?seed=`, or a URL already carrying a Deal's answers (any
+     of the shared block's fields — `hand` names the one always written)
+     all skip straight past this screen, exactly as `?lobby` already skips
+     past it into the lobby: those are not "no plan yet", they are a
+     choice already made, elsewhere.
+
+     THE SAME BLOCK THE DIALOG AND THE LOBBY USE, same shared module
+     (`settings-form.ts`), same order — three screens are one design now
+     instead of two. Only Solitaire can be dealt from here, so the other
+     four types are shown exactly as the in-game dialog shows them: present,
+     disabled, with a note pointing at the Multiplayer door instead.

-     It was a `prompt()` asking for a seed. Two of the three things that decide what kind of game
-     you are about to play had no way in at all: the opening hand had been changed twice with no
-     way back to the earlier rule, and the revenue rates were constants in the source. Balance is
-     the open question in this game (`TODO.md`), and the way to settle it is to deal several games
-     at different settings — which needs a dialog, not a rebuild.
+     `#newgamedlg` was a third copy of the same questions, and the one that drifted: it kept the
+     multiplayer wording ("Everyone loses if COMBINED Revenue…") on a screen only ever shown to a
+     solitaire player, and explained Employee Rotation in full beside a control it had disabled.
+     Deleting it removes the drift rather than re-wording it.
 
-     Every control has a default that is the recommended answer, so DEAL with nothing touched is a
-     complete, sensible game. The settings ride in the URL alongside the seed, because a seed alone
-     no longer names a game: `?seed=430` with a different opening hand is a different railroad.
-     ==================================================================== -->

-     * It got rarer for two compounding reasons, neither of them a broken rule: Gitea#14 took Red
-     * Flags from 5 copies to the sheet's 3, and Gitea#3 shortened most crossings to a single Stage,
-     * so the window in which a train is STANDING on a Mainline card — the only place the card may be
-     * played — is now usually one Stage wide.
+     * SINCE Gitea#19 the bot would take it every time — `worthFlagging` accepts the out-of-phase
+     * prompt unconditionally, because the engine only raises that prompt when an arrival is
+     * certainly about to collide, so there is nothing left for the bot to judge. It still never

-     * proves the bot has learned to use it.
+     * The reason is now arithmetic rather than judgement, and it is worth writing down because it
