Jesse.MarkowitzandClaude Opus 5 7c9ef8797d v0.8.0.12 — put a player back in their seat after losing their browser storage
Gitea#33. A session token is the only identity the game has, and it lives in
exactly one place the player controls: their browser's localStorage, scoped to
the origin they joined at. Lose it — a cleared profile, a private window, a
different browser — and the seat is unreachable while the game runs on and the
session sits intact on disk. Reported from the table: of two humans in one game
the host reloaded straight back in, the joiner met an empty lobby.

Diagnosed before it was fixed, and two server-side theories of mine were
retracted on the evidence: no storage key changed in 0.8.0.11, nothing in the
app deletes the secret or name, create and join both call persistSession, that
game's sessions.json held both seats, and it resumed with 80 intents replayed.
Both players used the same URL, so it was not a second origin either.

The fix is a recovery link. An administrator mints a code for a named seat
(admin-gated: deciding somebody lost a seat is a judgement no route can make);
the player opens the link and the page trades the code for the token over a
POST, then strips it from the address bar. The link never carries the token —
lobby-and-sessions.md §1 says keep it out of URLs, and a recovery link is
exactly what gets pasted into a chat. Single use, 30-minute expiry, held in
memory because a restart dropping them is the right failure.

server/claims.ts is a pure store, so single use, lazy expiry and one identical
answer for unknown/spent/expired codes are tested rather than asserted. The
admin game listing gained seatedPlayers — the seats a human holds a token for,
read from the session map rather than guessed from player names — so the
StartOS action can offer real players instead of bot chairs.

No rule changed: `git diff v0.8.0.11..v0.8.0.12 -- src/engine/` is empty, so
games in progress resume.

Jesse.MarkowitzandClaude Opus 5 9a9e50b3c6 v0.8.0.11 — sixteen fixes from the second multiplayer playtest
Arrivals name whose Office they reached, and no longer tell every seat they can
work the train. The turn chart follows the animation queue, so being five behind
looks five behind across the whole screen rather than half of it. Pause sits
beside Skip and preserves the dwell a held step still owed. A one-render look at
another player's Office Area. The district summary counts the board being shown.
LIMITS is printed beneath its card instead of through its border. The Mainline
region divider is visible. Only Hilly mentions FAST/SLOW, because it is the only
card that reads it. A passenger Modifier on a Whistle Post reports itself dormant
rather than claiming the facility "only receives". An automatic phase says what
the Division is doing instead of answering by negation. The version appears once
in the header rather than twice on every .s9pk. Save files carry the join code,
the Stage and the date.

The New Train phase, reviewed before being changed: the make-up panel now says
what the train STILL needs rather than only what its card calls for, explains
that a player adds one car before the round passes on, marks the train being
loaded on the Division map, and gives an addable car in the yard the same amber
every other clickable thing on the page wears.

Reasoning, measurements and the reports behind each are in CHANGELOG.md.

Jesse.MarkowitzandClaude Opus 5 4adf149ba5 v0.8.0.10 — playtest fixes: clearance rulings, the log, the map, and a save file
From the first two multiplayer playtests of v0.8.0.9, each traced before fixing.

The engine:

- A train on a card BEHIND the one departing no longer triggers a clearance
  ruling or an opposite-direction bar (#26). Reproduced from the exported
  save: X15 was held over X18 behind it, and X18 then collided into the full
  Whistle Post. Games in progress holding a ruling the engine no longer asks
  for will not resume (28 of 40 recorded four-seat games); shipped as is at
  Jesse's call.
- `mainlineModified` carries the card's previous kind, so the log can say
  what a Realignment converted (#27).

The screen:

- The turn chart and the Division map name the player whose move is on
  screen while bot turns replay, not the live actor (#25).
- The owning player's name is no longer outlined by the turn arrow's stroke,
  which made it unreadable (#24).
- A Mainline card flashes on the map when a Realignment changes it (#28).
- The history is held back with the board and revealed step by step, instead
  of arriving whole while the board is still catching up (#29).
- A ruling made by holding the office reads "Superintendent Player X" (#30),
  and no line names a player twice (#31).
- A seated player can download their own game as a save file: the play
  page's Save replay button, fed by GET /api/save?token=… (#32). The StartOS
  action cannot do this — an action result is text only.

Jesse.MarkowitzandClaude Opus 5 76c6e103b3 v0.8.0.9 — the bot plans its switching turn, stops wasting its draws, and the engine walks each route once
The developer bot, re-measured decision by decision against the bot before it,
goes from about -0.3 revenue a game to about 4.8:

- plans the whole switching turn before its first Move (sim/switch-planner.ts),
  +2.89 over 1600 paired seeds; closes TODO #53
- takes a face-up card only if it could play it, +1.52 over 1600 seeds
- stops running Second Sections by accident in the New Train phase, +0.32
- lays track by what the district can do afterwards, +0.12 over 6400 seeds,
  run-arounds in 22 of 60 districts against 9

The engine is 2.8x faster with play proven identical: a route cache scoped to
one unchanged position, applyIntent split into prepareIntent + commitEvents,
and less allocation in exploreMoves. npm test now leaves out the bot
simulations, which run as npm run test:sim.

No rule changed; games in progress resume. Rejected candidates and the
Second Section card question are in CHANGELOG.md and TODO.md (#104-#106).

Jesse.MarkowitzandClaude Opus 5 072029b1f7 v0.8.0.8 — a played train does not come back; a discarded one does
Jesse's ruling on the question v0.8.0.7 filed: once a regularly scheduled train has
been played its number is on the timetable, so putting it back into a reshuffled
deck to be played again makes no sense. The same card sitting in a discard pile was
never played and its slot is still open, so it should come back. An Extra is a
single run rather than a standing slot, so a played one is free to run again.

The test is therefore WHERE the card is, not only what it is — which is worth
writing down, because it is exactly the rule a later tidy-up would simplify into
filtering by kind everywhere.

And the duplicate that started it: trainScheduled was pushing a synthetic
train-<number> into the Salvage Yard beside the real card cardPlayed had already
put there — four scheduled trains left eight entries in a pile holding four cards.
Nothing read it, it inflated the depth, it displayed as "a card", and it would have
been swept into the draw deck to be drawn as an id with nothing behind it. Removed,
which retires the phantom-id class rather than papering over it, so v0.8.0.7's
cardName resolver for it goes too.

Games in progress resume: no predicate changed its answer, and a draw is a draw
whatever is on top. What differs is the Yard's depth, which was double-counting,
and what a reshuffle recovers — and reshuffles are effectively unreachable, with
zero seen across eight games driven to 4000 moves.

Closes #23.

Jesse.MarkowitzandClaude Opus 5 d0e5091824 v0.8.0.7 — the Salvage Yard had nothing to say, and phases too little time to read
The Salvage Yard was face up all along; its tile just read "a card". apply.ts
pushes a synthetic train-<n> id on trainScheduled, nothing in s.cards matches it,
and cardName fell through to its default — and since a train is scheduled several
times a Day that id is on top most of the time. Measured before touching anything:
the tile read "a card" from the opening frame through 60 pushes while its depth
climbed from 2 to 8. cardName resolves it now, in sim/view.ts, because this is a
name.

The engine half is filed as Gitea#23 rather than fixed here. reshuffleIfDepleted
sweeps the Salvage Yard back into the draw deck, so that synthetic id can be
shuffled in and drawn into a hand as an id with no card behind it. Eight games
driven to 4000 moves across eight seeds produced zero reshuffles, so it is latent;
there are two defensible fixes and the choice turns on what the synthetic id is
for, which is not a call to make while fixing a label.

And phases scale with the speed control again, damped to a third of the rate. They
were pinned in v0.8.0.3 because scaling them walled off a player's own turn; pinned
turns out to be too short to read at 10x. Damped satisfies both: 1x unchanged, 10x
lands exactly on the four-times guess. Bounded because phase beats cluster rather
than accumulate — 1.0 per push on average, 4 at worst, so the wait after a move is
~2.4s typical.

Jesse.MarkowitzandClaude Opus 5 64e8ce584f v0.8.0.6 — your move waits its turn, the lit pile keeps asking to be looked at
Your actions are put away while the board is catching up. The board on screen is
behind the game, so a move offered there is a move against a position that has
already moved on — and the screen had grown to four things competing at once: the
district, the history, the catching-up row, and a lit pile. Skip is one click away,
so the wait stays voluntary.

That could have locked a player out of their own game. Hiding actions behind busy()
makes that flag the thing standing between a player and their turn, and without
requestAnimationFrame nothing ever advances the queue — so busy() would never
clear. Caught by the DOM-stub test that has been proving this page still starts
since long before any of this existed. No rAF now means draw everything at once,
which is what pace 0 does deliberately, and a queue that throws empties itself
rather than stranding anyone.

The lit pile was never brief: measured, it stays lit for 6997ms at 10x. It was a
single flash over a dark fill, easy to miss while watching the district — a state
that settles stops asking to be looked at. It pulses now for as long as the move is
up.

And the pace ceiling was not theoretical. 10x was the top of the ladder and was
reported still a bit fast; it runs to 20 now. A control whose limit is reached in
ordinary use has the wrong limit.

Jesse.MarkowitzandClaude Opus 5 3fca325699 v0.8.0.5 — the Home Office deck, and lighting the pile a move touched
"Many operations still occurred too fast for me to see", at 10x — where an action
already holds the screen for seven seconds. So it was never duration: a bot drawing
a card changes one number in a panel nobody is watching, and the board sits
unchanged. Raising the dwell was the wrong lever and it had been pulled three
times.

f.deck has carried the face-down count since the Frame existed and nothing drew it
— the display gap test/display-gaps.test.ts sweeps for, surviving in the one panel
that draws every other pile. It is a tile now, first in the row, face down, because
that is the order a card travels and not knowing what is on top is the point.

And the piles a move touched are lit for as long as that move is on screen. Derived
from the frames either side of a step rather than sent, so nothing joins the
protocol and the 0.8.1 board gets it free. What lights follows what is public, and
was measured across four seeds rather than reasoned about: a Home Office draw
lights the deck and never names the card; a Department draw lights that pile, and
the deck too when it refills; a discard lights the Department it lands on; a played
card lights the Salvage Yard. Switching and new trains light nothing here — they
move the board, which the district panel already follows.

A state rather than a flash: the timetable's fixed 1.5s animation would be over
long before a seven-second pause. Not for your own moves.

Jesse.MarkowitzandClaude Opus 5 fc40fc39ed v0.8.0.4 — take the test server's name back out of the tracked files
Both repositories allow anonymous clone — checked rather than assumed: info/refs
for git-upload-pack answers 200 for each, git-receive-pack answers 401. So
everything committed here is public, and tracked files are supposed to carry
placeholders rather than real hosts.

Ten mentions added while building v0.8.0 are now "the test server" or "the target
hardware", across CHANGELOG.md, the common-board plan's three deferral banners,
sim/pacing.ts, and two test files. Prose and comments only, no behaviour; the
quotes are untouched, because what was said about bot pacing is the part worth
keeping.

Left alone deliberately: nineteen older mentions in entries about v0.7.5, v0.7.6
and v0.7.8 and in TODO.md, since rewriting a changelog after the fact makes the
record less true; and scripts/deploy-web.ts, where the host is the functional
default for FB_URL rather than prose — turning that into a required variable
changes how deploying works and wants deciding on its own.

Jesse.MarkowitzandClaude Opus 5 ff629c0708 v0.8.0.3 — Skip on the left, a caption that says who, and a clock that stops
stretching

Three things from playing v0.8.0.2, all about the row rather than the mechanism.

Skip was on the far right and a player's eye is on the countdown. Moved to the
left, in front of the count.

The caption said what but never who. Measured over 40 turns of a real 3-seat game,
half the waiting is automatic phases — 21.0s of phases against 21.7s of other
players — and a phase narrates as "Mainline", which is accurate and no answer at
all to "who am I waiting on". A phase introduces itself now: "The Division:
Mainline phase". A player's move already carries its name from record(), so it is
left alone. The row was also hiding one step early, because it showed only while
behind > 0 — which goes false exactly when the last step of a burst goes up, so the
step most likely to be read lost its caption.

And the speed control was stretching the clock along with the players. It was not
his own move being replayed — own moves have cost nothing since v0.8.0.1 — it was
the phases behind it, which put 105 seconds of clock-ticking into a 5x game. pace
now scales a player's move and leaves a phase at its tabled beat, which is what the
control has always claimed to do. Off still means off for both.

Jesse.MarkowitzandClaude Opus 5 c10f52791e v0.8.0.2 — the speed control that was only ever a URL parameter, and a Day-end
contradiction

Two things found by playing v0.8.0.1, neither in the mechanism itself.

?pace= never worked. index.html's doors are play.html?lobby and
play.html?solitaire, so arriving through the splash replaces the query string and
the play page only ever saw ?lobby — a whole game was played at 1x while believing
it was at 7x. v0.8.0 shipped that parameter as the only way to change speed and the
game's own front door destroyed it. There is a control on the play screen now,
beside zoom, persisted per viewer; the doors carry pace through as well, so the URL
lever is honest for handing two playtesters different speeds. PACE_LEVELS moved to
sim/pacing.ts with DWELL and MAX_PACE — the tuning surface in one file, and
testable. The committed default is unchanged: what it should be is a question for a
game played at a speed that took effect.

And the Day-end dialog said "0 today, 2 in all". advance.ts increments the Day and
then zeroes collisionsToday, and noteDayEnd() fires when the Day goes up — so the
dialog reporting the Day that just finished was drawn from the very frame in which
that Day's count was reset. Reproduced on four of five seeds before changing
anything. The count is captured at the rollover now; it is not derivable on the
client, because in multiplayer the push announcing the new Day is the same push
that carries the reset. And "today" was the wrong word regardless: it names the Day
instead — "Collisions: 2 on Day 1, 2 in all".

Unrelated to v0.8.0 — that one has been wrong since the dialog was built for
Gitea#10, and needed somebody to play a Day with a collision in it and then read
the summary.

Jesse.MarkowitzandClaude Opus 5 0cfeb4c496 v0.8.0.1 — bot play was way too fast, and the last step never got its moment
Two things from the first real play on phoenix.local. One bug: busy() was
pending.length > 0, so the final step of a burst reported the queue idle the
instant it was shown — the district panel snapped back to the viewer's own board
and the countdown row vanished before either could be read.

And calibration. "Start at 1s and tune down" was applied to switching, while a
250ms action tier was invented beside it — fine for a switching burst, wrong for
the common case, since switching is not legal until there is track down. A real
early-game bot turn measured 750ms end to end. Actions are 700ms now, and
localOps.choose moved out of bookkeeping: it is the line announcing what a bot is
about to do, and at zero dwell nobody ever saw it.

The viewer's own moves now cost nothing — their board comes from their own Frame,
so holding their click only delayed the thing they wanted to watch. And pace
supports 2 and 3 as asked, bounded by MAX_PACE so a typo cannot look like a
frozen board; every tier scales together, so the weighting survives any speed.

Jesse.MarkowitzandClaude Opus 5 02289e94b8 v0.8.0 — the board replays what everyone else did, instead of arriving rearranged
TODO #13, #15 and #18 — Gitea#20 steps 2-4 pointed at a seated player's own screen.
Every accepted intent, and every automatic phase that does anything, becomes an
ordered presentation step. A bot's whole switching turn used to land in one push;
now it arrives as a run of steps, the district panel follows whoever is acting,
and a [N behind] … [Skip] row says how far the board is from the game.

Solitaire runs the same path — one collector inside submit(), which both session
kinds already funnel through — which is where its automatic phases finally get a
visible beat.

Dwell is assigned by kind: switching holds the screen, turn bookkeeping costs
nothing, and the clock turning over earns the beat. Tunable per viewer without a
rebuild, and off entirely at pace 0.

Also: switching was the one class of action logging unattributed, and now names
its train. Reasoning, measurements and the three things that turned out wrong are
in CHANGELOG.md.

Jesse.MarkowitzandClaude Opus 5 312e0301e0 v0.7.9.8 — the test command did not typecheck, and the plan had gone stale
Housekeeping before v0.8.0: the answer to "anything else that should be
looked at first". One real hole, one stale document, and my own leavings.

#102 — `npm test` passed green on a type error. `pretest` ran
`scripts/build-web.ts`, which invokes `tsc --ignoreConfig` against three
web entry points, so it saw only what those three transitively import and
under a WEAKER configuration than tsconfig.json — no
`noUncheckedIndexedAccess`, no `exactOptionalPropertyTypes`,
`--types ''`. It never saw `src/server/` or a single file under `test/`.

Demonstrated rather than argued: a planted
`const DELIBERATE_TYPE_ERROR: number = 'not a number';` in
src/server/session.ts gives `npm run typecheck` a TS2322 and `npm test` a
clean `# fail 0`. `pretest` is `tsc --noEmit && node
scripts/build-web.ts` now, and the same error exits 1 with the tests
never running.

This mattered THIS week rather than generally: v0.8.0 is steps 2-7 of the
common board — display stream, credentials, persistence, Chromium
supervisor — which is almost entirely src/server/, exactly the half the
test command could not see.

#103 — the plan had drifted from the code it is the source for.
docs/plans/jitsi-common-board.md was written 2026-08-27, still said "No
implementation has been performed", and is what steps 2-7 get built from.
Step 1 shipped across four releases since, so every "current code
finding" under it described a fault that is now fixed — a document
reading as present tense and nine days stale sends the next reader to fix
things twice.

Measured: its PublicFrame sketch lists four properties never built
(protocolVersion, config, scoring, deckCounts) and omits 28 that exist,
and the shape is the real difference — the implementation is FLAT where
the plan grouped things into objects, so a renderer written from the
sketch would not compile. The plan now says so at the top and at step 1,
names src/sim/view.ts and the redaction allow-list as the authority,
keeps the original sketch for its reasoning, and calls out
`protocolVersion` as unbuilt rather than dropping it quietly — step 2 is
the reconnecting display stream and is the first thing that would want
one.

One step-1 item is STRUCK OFF rather than built: "add the Red Flag holder
to the public player projection". The premise does not hold here.
`decks.redFlags` is written once, in setup.ts, from
`optionalRules.emergencyToolbox`, and never again — `redFlag.play` emits
`phaseEnded` and does not spend it — so every player holds one or none
does, decided before the deal. A per-player `redFlagHeld` would be one
already-public option copied N times, while telling every reader of the
common board that it varies by player and might change mid-game. Worse
than the absence. Pinned by test so it is not re-raised from the plan.

Four dead imports removed, all mine: `HAND_LIMIT` left unused in
apply.ts, view.ts and web/game.ts when 0.7.9.6 consolidated the three
copies of the §6.2 test, and `actingPlayer` in web/game.ts, dead since
0.7.9.5 made `currentActor` delegate. Finding them re-measured #46:
`tsc --noUnusedLocals` now reports 40, up from 29 on 2026-08-30. That
entry's "without the flag this list simply regrows" is a measurement
rather than a forecast now. The other 36 and the flag stay open.

946 tests pass, up from 943. No behaviour changes: three new tests pin an
invariant, and the rest is a build command, dead imports and a document.

Jesse.MarkowitzandClaude Opus 5 88a42ae9e2 v0.7.9.7 — a device that said it was available all day after it was gone
The last item off 0.7.9.6's sweep, parked there as the one genuine maybe.
It had a second half worth more than the first.

#101 — Telegraph (+4), Telephone (+8) and Radio (+12) are "once a day,
when dispatching facing trains, add +N to the other train's number".
`enhancementText(key)` takes only the KEY, so the tooltip could not vary
with anything: a spent Radio read "Once a day, add +12..." for the rest
of the Day, advertising a bonus that was not there. That is `trainRules`
before #100, in another corner of the same view.

THE HALF THAT ACTUALLY SURPRISES. `spendDispatchBonus` reads
`areaOf(s, s.clock.superintendent)` — the SUPERINTENDENT's own devices,
not the train owner's — and the Fedora moves every STAGES_PER_SHIFT (3)
Stages, four times a Day. So a player's Radio does nothing at all for
three-quarters of the Day, and is spent automatically, without its owner
being asked, during the quarter it is theirs. Neither half was anywhere
on the board.

The card now reads as one of three states — available and dispatching,
unspent but idle while somebody else holds the Fedora, or spent until the
next Day — and names the shift length, because "not now" without "for how
long" is half an answer. A spent device is struck through on the board.
Shown on EVERY district, not only the viewer's (Jesse's call): it is
public, and a rival's spent Radio is what you want to know before forcing
a meet.

What counts as a device is `enhancementRule(key)?.dispatchBonus` rather
than three keys written out in the view — the ladder lives in
ENHANCEMENT_RULES and a fourth rung would otherwise be silently exempt.

A STALE COMMENT CORRECTED, AND PINNED. `advance.ts` warned that indexing
a SEAT-keyed area with the PLAYER holding the Fedora "is right only while
seating is the identity map". It read as a live Employee Rotation bug and
was not one: `areaOf(s, p)` IS `areaAtSeat(s, seatOf(s, p))`. A comment
that sends the next reader chasing a bug that does not exist costs about
what the bug would. Rewritten, and the claim is now a test — seating set
to a real permutation, and the Superintendent's own district rather than
the seat with the same index is the one that reads as dispatching.

TWO THINGS MUTATION CAUGHT THAT PASSING DID NOT. A test asserted the
ABSENCE of /spent|Fedora/ with the Fedora held, and a mutant with the
`dispatchBonus` guard deleted PASSED it — the leaked text in that case
says "Available today, and this district is dispatching", which contains
neither word. A test that something was left alone has to compare it
against what it should be, so it asserts equality with `enhancementText`
now, in both Fedora states. And the replay wire format needed the field:
cells pack positionally, so the flag is index 9 and reads `?? []`, the
same tolerance `standingWest` uses — older recordings report no device
spent, which is what they drew at the time, so every published replay is

Jesse.MarkowitzandClaude Opus 5 7f4e027258 v0.7.9.6 — three things the engine knew and the screen did not
Found by looking rather than by being told. Gitea#21, #22, #94 and #96
were four instances of one fault in a row — the engine gains something
that changes what a train may do, and nothing draws it — and every one
was found by a player hitting it. So instead of waiting for the fifth,
every field of GameState and its nested types was enumerated, checked for
a reader in sim/view.ts, src/web/ and sim/narrate.ts, and the survivors
verified BY RUNNING THE ENGINE rather than by trusting the grep.

Four fields had no reader. `movedThisPhase` lives and dies inside one
`advance` call and is nobody's business. The other three are below. What
was ruled out matters as much: `freightWorked`, `drawnThisTurn`,
`freightAgentUsed`, `switchedSince` and `movesUsed` are invisible on
purpose, their effect already showing as legality or as a complement
already on the Frame. A field is not a display gap merely because nothing
renders it.

#98 — the Crew Tray pool. §7 scarcity is called an explicit mechanic and
was explicit only in the engine. The blocked panel had one tray rule,
keyed off the train due out this Stage, so a player who spent a card on
an Extra or ordered a second section got an EMPTY panel while their train
sat behind an exhausted pool — both having been announced once in the log
in a line promising a future event that nothing then confirmed. The
shared table carries the pool and the queue now, so the common board gets
it too, and the panel reports all three with the count beside them.

#99 — a train held at the Limits vanished off the board, and this one had
shipped. The Interlocking stops an inbound train on the Limit Track
rather than colliding with a full Office. `arriveAtOffice` removes the
tray from the Mainline node's `transits` and the Interlocking branch
pushes it onto `heldAtLimits` without assigning `tray.position` — and the
map draws mainline nodes from `transits` and squares from
`position.at === 'grid'`, so between the two it was drawn in NEITHER. It
disappeared on arrival and reappeared in the Office some Stages later.
Fixed in the view: the engine is right, and `position` is left alone
deliberately so nothing treats the train as standing somewhere it could
be switched from.

#100 — the Campaign Train's speeches change its rules, and the card said
the same thing before and after. Worse, the "EXPEDITED ... costs 1
Revenue" warning prints only under `rules.expedite`, so X17 became
subject to a fault whose warning the game shows to every other expedited
train and never to it. `trainRules` reads `speechMade` now and borrows
`isExpedited` from advance.ts rather than restating the test.

#45 — the 0.7.9 dead-field audit, finished, and the answer was different
for each. `overHandLimit` is WIRED: its consumer existed all along and
was inferring the hand limit from the ABSENCE of `draw.end` in the menu,
which is sound only while `check` keeps refusing for exactly three
reasons. `viewerSeat` is DOCUMENTED, with a condition — Gitea#20's board
keys districts by seat, and the note says to delete it if step 2 ships
without using it.

The audit had missed a third limb. `game.mustPlayCard` was assigned on
every submit and read by nothing: deleted. Chasing it turned up the thing
worth fixing — the §6.2 hand-limit test existed in THREE places, all
agreeing, which is the state #96's disagreement started from. One
`overHandLimit(state, player)` in state.ts now, and the other two ask it.
`Session.overHandLimit()` is deleted rather than kept: the Frame already
carries the fact, so the method was a second path to it.

934 tests pass, up from 917. The 17 new ones were written red, and each
fix checked by mutation: reverting `speechMade` fails 2, dropping the
held-train projection fails 4, forgetting the tray queues fails 2. The
empty blocked panel is reported beside its positive control, since an
empty result from a broken function proves nothing.

NOT VERIFIED AT A TABLE. Engine and view work, checked by tests and by
running the engine. #39 and #35 still stand.

Jesse.MarkowitzandClaude Opus 5 d5445badcc v0.7.9.5 — two answers to one question, and the copy nobody read
Both faults are in what 0.7.9.4 had just built, and both are the same
shape: a second copy of an answer that agreed with the first until it
didn't.

#96 — the §3.3 vote has no actor, and the screen named one anyway. The
vote is PARALLEL: every un-voted seat may vote at any moment, in any
order, one refusal ends it, and `apply.ts` says where it accepts one that
there is no actor to be. The turn chart named the last seat to move
before the timetable ran out — no more claim on the vote than anybody
else — directly above a tally correctly showing three seats outstanding.

The cause is worth more than the symptom. `currentActor(game)`
(`web/game.ts`) guarded on `status !== 'active'`; `currentActorOfState`
(`sim/view.ts`), added the same day in #95 and the one the frame calls,
did not, so it handed back whatever `clock.currentActor` was left
holding. The view now carries the guard and `currentActor` delegates to
it. That matters more than the tidiness: `currentActor` is what REFUSES
an intent, so a screen answering differently tells the table to wait on a
player the server would turn away.

The fourth of this class after Gitea#21, #22 and #94 — but the first
found by asking a view helper its question in a state the game is not
`active` in, which is the generalisation and is cheaper than finding the
fifth the same way.

#97 — narration reaches a seat once, by one path. `Frame.lines` carried
the whole log on every push to every seat, and nothing read it:
`RemoteSession` accumulates from `push.lines` alone and its `lines()`
returns that accumulator, so the log was serialised into every frame,
grew all game, and was discarded on arrival while `linesSince` sent the
same text correctly beside it.

The duplicate was masking a bug rather than merely wasting bandwidth.
`connect()` cleared `lastFrame` but not `sentLines`, so a reconnecting
seat was told "nothing new since your last push" while the browser it
answered had just reloaded from an EMPTY accumulator — the history panel
came back blank, mid-game, with the server holding the whole log. So the
two halves are one change, and the plan's instruction taken alone ("stop
passing the full game log into `frameFor()`") would have deleted a real
behaviour rather than a duplicate.

Every remaining reader of `Frame.lines` was checked before the field was
emptied: all of them are the solitaire and replay path, which builds
Frames through `snapshot()` directly and never goes near a session.

One test was wrong before the code was. The first draft of the reconnect
test connected inside its own fixture, so both sides of the comparison
were the empty array and it passed against the broken server. Each test
now asserts its premise is non-empty before comparing.

Also: `docs/plans/jitsi-common-board.md` is committed. It was never added
— not ignored, just missed — while TODO.md cites it twice as the plan for
all of v0.8.0 and the last two releases were built from it, so a clone
got a TODO pointing at a file that did not exist.

917 tests pass, up from 909.

Jesse.MarkowitzandClaude Opus 5 ebd16983e2 v0.7.9.4 — Gitea#20 step 1, and a Red Flag you can see
Step 1 of the common board done as its own release rather than as the
first hour of 0.8.0, since both halves of it are worth having whether or
not anything is ever published to a call.

#95 — the public projection helpers. `projectDistrict(state, seat)`,
`projectDivision(state)`, `projectSharedTable(state)`,
`publicSnapshot(state)` and `currentActorOfState(state)`, with
`snapshot()` REBUILT to compose from the same helpers rather than keeping
a second copy of the shared table, so a player's frame and a spectator's
cannot come to disagree about the clock, the phase, whose turn it is or
the score. Behaviour-neutral; the 897 existing tests passing unchanged is
the proof.

The public view is composed UPWARD, never by calling `snapshot()` once
per seat. That shortcut is the trap the plan names: `snapshot` assembles
one player's view, so a public view made of player views builds every
private field and then has to remember to strip it — and it defaults its
viewer to player zero, so a careless spectator call would have served
seat 0's hand. Districts are keyed by SEAT with the player resolved
through `playerAtSeat`, because Employee Rotation moves players between
districts and a board that treated seat and player index as
interchangeable would relabel every district the first time anybody
rotated.

One plan finding is struck off rather than fixed: it warns a display
reading `clock.currentActor` could highlight the wrong district during a
decision. Measured over six seeds and 3,600 decision points, that field
and `actingPlayer` never disagreed. `currentActorOfState` exists anyway,
as one place for the next reader to ask.

#91 — the redaction net, systematically. v0.7.9.2's two leaks were found
by reading a plan, not by a test, which is the whole argument for this: a
suite made of the leaks somebody happened to notice proves nothing about
the next one. Serialise a seat's Frame, the PublicFrame a spectator gets
and the narration they receive, then search all three for every opponent
card id, every card name unique to one opponent's hand, the seed and any
private decision or menu data — across a fresh game, a blind draw,
mid-game, a pending decision, Employee Rotation before and after the
seating moves, a reconnect push (a full Frame, and its own opportunity to
leak) and a played-out game. And the allow-list, which is the plan's
stated acceptance bar rather than the tests: every property of
`publicSnapshot` is written down with its reason and compared on every
run, so adding a field fails the suite until somebody has said out loud
that a spectator may see it. Both v0.7.9.2 leaks were fields nobody had
ever asked that question about.

Proved by mutation rather than by passing: restoring the seed line fails
6 tests, restoring the blind-draw card name fails 1, adding a private
field to the public projection fails 7, and making `players[]` carry hand
contents instead of a count fails 5.

Two false failures were worth the lesson. A card NAME is a type, not an
identity — "right-hand curve" names a dozen cards and one is legitimately
a cell label the moment anybody lays track, so searching for it fails on
correct code, which is worse than not searching; a name is evidence only
when every card bearing it is in the one hand. And a one-digit seed makes
the seed check meaningless: seed 7 matched "Train 7". One item on the
plan's list has no test because it has no referent — there is no secret
objective in this game, `objectiveOf` deriving from
`config.minCombinedRevenue` and the player's own Revenue, both public.

#94 — a Red Flag standing at an Office's Limits is on the map. It is a
token set out ON the board that holds the next train arriving from that
side, and it was announced once in the log and drawn nowhere, so a train
stops short three Stages later with its only explanation scrolled out of
the panel. `DivisionView`'s office node carries `redFlag` and the map
draws a staff and pennant AT THE END IT GUARDS — west on the left, east
on the right — because which approach it covers is the whole of the
information; a flag in the middle of the cell would say one is out and
leave the reader to hover for the half that decides whether to run a
train. The tooltip leads with it, ahead of everything that merely
describes the cell.

The third of these in a row after Gitea#21 and #22: when the engine gains
something that changes what a train may do, the question to ask is where
it is drawn, not whether it works.

909 tests pass, up from 897.

Jesse.MarkowitzandClaude Opus 5 819996faa2 v0.7.9.2 — two things the table could hear that only one seat should
Both leaks were found while planning the common board (Gitea#20 step 1),
and both are live multiplayer bugs with or without that display, so they
are fixed now rather than with 0.8.0.

`game.log` is one shared list and `linesSince(seat)` slices it with no
per-seat filter, so every line reaches every player. It carried the SEED
in the opening line of each multiplayer game — the whole future of the
deal — and the NAME OF A CARD DRAWN BLIND from the face-down Home Office
deck. Solitaire deliberately keeps both: a one-seat table has nobody to
leak to, the seed is what a bug report quotes, and a player's own history
naming their own draw is the record. A Department slot is face up and
stays named. The drawer still learns their card through `justDrawn`,
which already goes to that seat alone.

Neither was found by a test. Every test in `redaction.test.ts` passes an
empty log, so the whole of narration has sat outside the redaction net
since the net was built. Both now have tests there; TODO #91 carries what
is still owed and supersedes #78, which described a gap that had already
been closed and never mentioned this one.

`docs/rules/` had no current description of the game, and `content.ts`
named `card-reference.md` as the file that carries what the cards say —
a file whose own banner says not to use its numbers, describing the
v0.4.5 deck where 3/4 is a Mail-Express with three coaches. Every file in
that directory is a deliberate historical record, so none of them is
rewritten. `as-built.md` is new and GENERATED from the same catalogues
the engine instantiates from, with a test that re-runs the generator and
fails when the checked-in file disagrees. A hand-written replacement
would have drifted the same way, for the same reason.

TODO.md: #32 closed — the playtest migration note did its job and the
jump is made; the durable fact it carried is kept. #78 retired in favour
of #91. The "play it at a table" section now records that 0.7.4-0.7.9
were test-run without change requests, and that more testing comes at the
end of the 0.7.9 series.

897 tests pass, up from 891.

Jesse.MarkowitzandClaude Opus 5 7ade60e21f v0.7.9.1 — the engine was right twice; the screen was not
Gitea#22: the Division map drew every westbound train in the wrong half of
its Mainline card. `regionOfTransit` counts from the end a train entered,
which is what the collision rules ask; the map wanted "which printed box,
left to right" and used the same number, so an eastbound train came out
right by luck and a westbound one came out mirrored. It cost a collision —
Train 3 was cleared to follow T5 and ran into TX17, which the picture had
drawn ahead of T5 rather than behind it. One mirror in `view.ts`, at the
boundary the map is drawn from; the collision rules are untouched.

Gitea#21: a second tank car would not come off at a refinery, and "Blocked
— why nothing is moving" answered by describing the refinery's green box.
The real answer was Train 3's printed rule — the Express works one freight
car per location — so the refusal was correct and the panel sent the player
to spend a Freight Agent action that could not have helped. No rule
changed. The panel now names the budget, asking the reducer's own
predicate so its words cannot drift from the rule.

Both were replayed from the saves attached to the issues and verified in
the exact position each report names. The map fix is proved by mutation:
reverting the mirror fails two tests, and making the renderer ignore the
region fails a third. Every existing region test ran eastbound, where the
mirror is the identity, which is why the bug survived them.

891 tests pass, up from 884.

Jesse.MarkowitzandClaude Opus 5 e62ea54259 Four things the game counted and never said, and two it said wrong
Stays in the unshipped v0.7.9. Prompted by Jesse asking the general
question after two v0.7.9 fixes turned out to be 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 computed, serialised and sent to nobody?

THE AUDIT, done 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. Four are not.

tally.unloadsBegun 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, reporting half of a symmetric
mechanism. tally.cardsDiscarded was counted by the engine and listed
beside "Cards drawn" and "Cards played" without it, though Gitea#9 made
throwing a Timetabled train away a deliberate move — a player CHOICE
the game counted and never reported. Both are reported now.

viewerSeat and overHandLimit are deferred by Jesse. The second is the
fullest version of the shape: 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, no consumer. The decision when it comes is
delete-or-document, not a patch.

Fixing the two turned up a third thing: resultsHtml draws
tallyHtml(report?.tally ?? f.tally), and report is f.official, so a
finished game reports the tally frozen at the official ending rather
than the live one. The first attempt at a test overrode f.tally alone,
changed nothing on screen, and failed for a reason unrelated to the
fix.

A SHOUTED KEYWORD IS NOT A SENTENCE. `EXTRA X18 started…` attributed to
a player rendered as `Player Solitaire eXTRA X18 started…`, and the
same happened to TRAIN 1 MADE UP and COLLISION. `record` folds a
narration's opening word into the middle of a sentence 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 also
leaves X22 Pee-Dee alone, where a naive uppercase test gets it 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 ruled balance work out of scope.

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.
submit attributes and fromMultiplayerSave attributes; this was the one
path of three that did not. One argument, with actor already computed
on the line above.

Why it survived: 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 undo itself rebuilds
through fromSave — so the gap cancelled out on both sides. The suite
was green with the bug in and green with it out. The new test plays a
game, saves it, restores it and asserts the two logs are identical:
the missing direction, not a new requirement.

All three fixes were confirmed to go RED with the fix reverted before
being called done.

884 tests pass, seventeen new.

Jesse.MarkowitzandClaude Opus 5 d267f89a82 The screen does what you tell it — three Display items, and a fourth declined
Reviewed with Jesse out of TODO.md's Display section. Stays in the
unshipped v0.7.9.

#17 (hiding the Division map) was DECLINED, and the reason is that its
premise had already died. Gitea#18 replaced the wrapped layout with a
single row, and the reason to fold the map away was that it GREW — a
horseshoe of three or a square of four pushed the board off the screen.
One row is boardH = PAD * 2 + CH + 30: 150px, fixed, at every seat
count. That is not worth a control, three states and a persisted
preference. It was a sixth member of the drawing pass that got closed
with Gitea#18 and stayed open only because it reads as a control
question rather than a drawing one — recorded in TODO.md as an explicit
decision, with the design that had already been worked out kept, and
with the one thing that would justify reopening it: the map growing
again.

#16 THE OFFICE AREA'S AUTO-HIDE COULD NOT REACH EVERY STATE. One button
cycling auto -> pinned -> auto, where the pin was `open ? 'closed' :
'open'` and `open` is what auto is doing AT THAT MOMENT. So the pin a
press offered depended on the phase, and going from always-show to
always-hide meant clicking back to auto, waiting for the phase to turn
over, and clicking again. Three controls now, one per mode. The labels
still say what pressing DOES, which was an earlier deliberate fix; what
the cycle could not do was report the state it was in, and aria-pressed
carries that now.

They are addressed by id rather than queried off the container, and
that is testability rather than style: the stub DOM the web suite runs
against only models markup the page WROTE, so a child query finds
nothing and the control would have shipped green and unexercised. The
test presses always-show to always-hide directly — the transition the
cycle could not make.

#23 THE HISTORY READS NEWEST FIRST. Jesse: "the top line is the most
recent and the further down you go, the older the entry." The phase
headings now trail the lines they announce, ruled acceptable rather
than overlooked: "stage changes will be beneath (prior to / older than)
the following events. That is OK." Reading down is reading backwards.
Grouping by phase and reversing the groups was offered and declined as
more machinery than the complaint needs. replays.ts keeps its
oldest-first log deliberately — it is paired with a frame stepper,
where newest-first would fight the stepping. The slice(-60) cap is
untouched and stays open.

#28 THE SETTINGS MOVED INTO A CARD. The top line carried six things and
now carries four: Revenue, the objective, the collision counts and the
game code. The rest is a This Game card at the foot of the right-hand
column, folded by default. Nothing new travels for it — configFromFrame
already existed and main.ts already called it three times, so
rulesListHtml(configFromFrame(f), ...) needed no refactor, and the card
draws from the same renderer as the lobby's join preview so the two
cannot drift.

THE COLLISION COUNTS ARE NEW ON THE BOARD, NOT 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 — the second time this release that the Frame had the answer
and the view never asked (see #43's actingPlayer). They stay on the top
line while the limits go in the card: a limit is agreed to once, "2 of
3 today" changes how you play the next Stage.

One stub gap closed to get here: none of the five element factories in
test/web.test.ts had setAttribute, so the first render threw and any
control reporting state through ARIA was untestable.

WHAT IS NOT VERIFIED: the layout. There is no browser on this box, so
nothing has confirmed the segmented control, the card or the reversed
panel look right on screen. The logic is tested; the appearance is not,
and wants the next play session.

881 tests pass, fourteen new.

Jesse.MarkowitzandClaude Sonnet 5 bb1b661211 A game you come back to has not begun
Reported by 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 the two apart. It flashes "The game has resumed — Day 3,
Stage 7" now, on both ways back in: 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.

Stays in the unshipped v0.7.9. 878 tests pass, eleven new.

Jesse.MarkowitzandClaude Sonnet 5 a70b7f88f3 Say who the game is waiting on, and move the Fedora; replay in words
Three items folded into the unshipped v0.7.9.

WAITING ON (reported by Jesse from play). The status line said "nobody —
the Division is running itself" while the game was stopped on the
Superintendent. Frame.actor carried clock.currentActor, which is null
for the whole Mainline Phase, so all three interruptions — §8.1's
clearance ruling, Gitea#5's Yard Office offer, Gitea#19's Red Flag
prompt — reported that nobody was holding it up. actingPlayer had the
answer since the Gitea#5 refactor; the Frame threw it away. It carries
actingPlayer now, plus a new `awaiting` field naming the question and
the train: "waiting on Bob · a clearance ruling · Train 4". Naming the
person alone is not enough when three different things can be pending.

THE FEDORA (TODO #29) rides at the right-hand end of the phase row
instead of a line of its own, and wraps under rather than squeezing the
chips.

THE DEVELOPER REPLAY (TODO #34) printed "loss — revenueFloor", the same
defect Gitea#16 was filed about, still alive because nothing
player-facing pointed at it. panels.ts's reasonSentence is exported and
shared rather than reimplemented, fed the last recorded frame and
stripped of markup. The drift test maps win/loss to won/lost so it still
checks the two AGREE rather than that they are spelled alike.

Also carries the previous, unsigned commit's work: the two setup screens
worded the same section by section.

Jesse.MarkowitzandClaude Sonnet 5 131538dc7c Two setup screens, not three — the in-game dialog is deleted
Jesse: "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: shown only to a solitaire player, it asked "Everyone loses if
COMBINED Revenue…" and explained Employee Rotation in full multiplayer
terms beside a control it had disabled. Both were on the list to
re-word; deleting the screen removes the drift instead of restating it.

New game opens the setup screen IN PLACE rather than navigating, so the
live session stays in memory: the fields open on the rules actually
being played (what the dialog was good for), and Continue Existing Saved
Game puts the board back with no reload. render() calls save() every
frame, so nothing is at risk either way.

The two remaining screens now match below their headers — same three
parameters in the same order, same seed note, same chair note. Solitaire
shows Players at the table locked at 1 rather than omitting it: a fixed
control says "same form, table of one", a missing one made it a
different form sharing a rules block.

Drift guard drops to two prefixes and now fails if any ng- id returns.

Stays in the unshipped v0.7.9. 874 tests pass.

Jesse.MarkowitzandClaude Sonnet 5 cf018b4a5f A Heavy Grade shows which way it climbs
Jesse: "heavy grade mainline card tooltip states climbs east, but card
doesn't show it." The Frame has carried gradeUp all along and the tip
has said it; the card drew nothing, so the one Mainline card whose
orientation is set per game was the one you had to hover to read.

A brown wedge in the lower right rising toward the climb, with a bone
arrow lying along its slope, centred on the triangle's centroid. East is
right on this map (Gitea#18), which is what lets a wedge be read without
a compass.

Four passes. Up the hypotenuse the arrow began at the wedge's thin
corner, where there is no height, so its head 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. Parallel to
the slope is the shape that fits: the gap to the hypotenuse is then
constant, so the arrow can sit centred. The wedge grew to 58x24 to pay
for it, since a centred arrow has less room than an off-centre one.
Sizes are a search result, clearing every edge by 2.88px.

The first containment test bounded the arrow against the CARD, which it
never left, while the wedge clipped it — a green check on a visibly
broken glyph. It checks the TRIANGLE now with a 2px floor, plus
parallelism derived from the wedge and centroid placement.

Orientation is always set, measured not assumed: 400 seeds x 4 player
counts, 535 grades placed, 0 without one, 276 east / 259 west.

Stays in the unshipped v0.7.9. 874 tests pass, one new.

Jesse.MarkowitzandClaude Sonnet 5 45cf521a40 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. configWith({ days: 1 }) asked a
one-Day game to clear 15, which a full five-Day game averages barely
half of; configWith({ days: 10 }) asked for that same 15. It derives
from the days it was 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. Found
by a throwaway probe that passed only days — which is how the next
caller would reach for it. Unchanged at the default day count, since
SOLO_CONFIG's floor is this same formula at DEFAULT_DAYS.

Stays in the unshipped v0.7.9 per Jesse — no version bump for the next
several fixes. 873 tests pass, three new.

Jesse.MarkowitzandClaude Sonnet 5 e035dda5a3 The extension question was hidden behind the results screen (Gitea#11)
Jesse, playing v0.7.8: "Solitaire game ended. I did not have an option
to extend the game by a day."

The engine and the Frame were right — checked before changing anything.
A solitaire game at the end of its timetable reaches awaitingExtension
with extensionVotes [null], and renderEnding writes "play one more Day"
into #actions. It then opens #resultsdlg, which is MODAL, so those
buttons were directly underneath a dialog whose only control was Close.

The results dialog now carries the question itself, hidden unless a vote
is pending: Play One More Day / End the Game Here, casting the same
game.extend intent. The #actions buttons stay as the fallback once it is
closed.

TODO.md #35 recorded extended play as verified on phoenix.local — over
the HTTP API, which renders no dialog. What was proven was that the
server supports it, not that a player can reach it. Noted there.

Rides along in the unshipped v0.7.9. 870 tests pass, one new.

Jesse.MarkowitzandClaude Sonnet 5 f2c87b6871 v0.7.9 — solitaire setup screen feedback, and the dead settings it exposed
Four pieces of feedback from Jesse on the solitaire setup screen.

THE COLLISION LIMITS DID NOTHING IN SOLITAIRE. Asked to reword those
entries to "the game ends immediately and results in a loss", which was
unwriteable: advance.ts gated the §3.4 check on competitive/coop, and a
solitaire game's mode is 'solitaire'. Both limits were offered as live
settings, rode into the config, and never fired — the existing text was
already false. The exclusion was never a stated rule and nothing
recorded a reason for it. Jesse's ruling: the settings do what they say,
so the gate is gone rather than the controls.

Measured, not asserted — 200 standard developer-bot games:
loss/collisionFloor 1 in 200, Days played 5.00 -> 4.98 mean with a
minimum of 1, collisions per game unchanged at 0.14. Recorded in
TODO.md under Play Balance, since full-length figures predate it.

Extra start defaults to ownOffice: at one seat it is the same rule as
anyOffice (apply.ts only rejects another seat's start), so this is a
label fix with no gameplay effect.

Also: collision wording on all three screens, Employee Rotation reads
"not applicable for solitaire", and the save warning is legible at 14px
on an amber panel with buttons that say Continue Existing Saved Game and
Deal New Game.

869 tests pass, two new; one asserted the opposite of the ruling and
says so where it was reversed.

Jesse.MarkowitzandClaude Sonnet 5 193800a649 v0.7.8 — the setup screen was unreachable for anyone who had ever played
Third report of the same symptom, this time with the build confirmed
current on screen, which ruled out v0.7.7's caching fault and left the
real cause exposed.

v0.7.5 skipped the setup screen whenever load() found a save, reasoned
as "a saved game is a game to resume". A browser that has ever played
solitaire always has one, so the door could never reach the screen
again — and the fresh private window that appeared to vindicate v0.7.7
simply had no save. Two real faults were stacked; the caching one is
fixed and had been masking this.

The door outranks a saved game now: ?solitaire is a request to set one
up, while a bare reload still resumes (pinned by its own test). Since
Deal clears the save, the screen carries #ss-resume and says what Deal
costs, so the door cannot destroy a game in progress.

Also, per Jesse, riding along rather than taking its own release: the
splash footer now names both ways to play.

868 tests pass, four new. The reproduction was a failing test written
before the fix.

Jesse.MarkowitzandClaude Sonnet 5 af68aac78d v0.7.7 — two releases shipped to a browser that never received them
buildStamp()'s no-git fallback was the literal "nogit", and the .s9pk
Dockerfile copies the tree in without .git — so git rev-parse fails on
every packaged build. That string is also 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 returning browsers refetched
nothing. v0.7.5's setup screen and v0.7.6's door fix were both correct
and neither arrived.

The fallback is now the package version plus the build timestamp, always
distinct. And serveStatic sent no Cache-Control at all, which is the
other half — a cached play.html pins a player to the whole build it
names. A request carrying ?v= is now immutable for a year; everything
else is no-cache. ?v= rather than "not HTML" because build-web.ts tags
the modules and nothing else.

Neither half is sufficient alone.

Jesse.MarkowitzandClaude Sonnet 5 b4f09f05cb v0.7.6 — the solitaire door could not reach solitaire
Found by Jesse playing v0.7.5 on phoenix.local: a browser that had ever
held a multiplayer seat could not reach the new solitaire setup screen
at all. start() checked a browser-remembered multiplayer session before
ever looking at solitaire's own state, and a bare ./play.html load could
not tell "clicked Play solitaire" apart from "reloaded mid multiplayer
game" — the same problem ?lobby already solved for the door on the
other side, never applied to this one.

The door now links to ./play.html?solitaire, and start() treats that,
an explicit ?seed=, or the setup screen's own ?hand= (written by every
Deal) as proof this navigation means solitaire — checked ahead of the
remembered-session lookup rather than only below it.

862 tests pass, three new.

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

Jesse.MarkowitzandClaude Opus 5 19a6a47ab6 v0.7.4 — Red Flags hold a train out of your Limits (Gitea#19)
"If played, asked FLAG EAST or FLAG WEST. That stops all trains from entering your
limits from that direction (i.e. Flag East holds westbound trains). You can do this
if you see a problem or wish to complete switching."

REPLACES the old rule outright, per Jesse's call. Red Flags used to be played on a
stopped train out on the Mainline and protected it from a rear-ender: offered 4,212
times and played 4 across 600 games, a mechanic nobody used, and ABS Signals already
does that job better. The flag is now planted on one side of your own district and
holds the next train arriving from that side.

SPENT ON THE TRAIN IT STOPS. One card, one train, so there is no lifting action to
build, nothing to forget, and a flag cannot quietly strangle the Division. The held
train loses one Mainline Phase and comes in on the next — it buys a Stage to clear
the lead, which is what "wish to complete switching" asks for.

PLAYABLE OUT OF PHASE, which is the other half of the issue: when an arrival would
certainly collide and the district's owner holds the card, the phase breaks in and
asks. Offered ONLY to somebody holding one — a prompt with a single button is not a
choice, and it would leak that a collision is coming. The danger is read from §8.3's
own two triggers rather than restated, so the prompt cannot offer a flag against a
collision that will not happen.

Built on the decision union Gitea#5 introduced: this adds a `redFlag` case and
nothing else structural.

THE BOT STILL NEVER PLAYS IT, AND I MEASURED RATHER THAN ASSUMED. It now takes the
out-of-phase prompt unconditionally — the engine has already established the danger,
so there is nothing left to judge — and over 200 solitaire games `redFlagsSet` fires
ZERO times. The prompt needs an arrival that would collide (0.14 per game, about one
game in seven) to coincide with holding the card from a three-card hand out of 121.
So the anomaly exemption in sim.test.ts stays, but its comment no longer claims the
bot is unwilling: it is measuring deck luck. What is left to fix is the half of the
card a human would use, planting a flag on purpose to buy switching time, and TODO.md
now says that instead of the old finding.

A BUG WORTH RECORDING, 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 state and then describes it. 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 on it deliberately now,
with the reasoning.

858 tests pass.

Jesse.MarkowitzandClaude Opus 5 228027637b The Yard Office is offered, reachable, and can be run into (Gitea#5)
"Trains that are only freight (cabooses ok, no coaches allowed) that arrive in a
player's area who has the yard office card get an extra ability… the game will
offer that player the option… They can of course still choose to have the train go
to the standard office."

It was implemented, in a stripped form missing all three conditions: a qualifying
train was TELEPORTED onto the Yard Office card. Nobody was asked, no route was
computed — so the card's own printed "that can reach the yard office in one move"
was unenforced — and because nothing was walked, nothing was ever met on the way.

All three now hold:

  - OFFERED to whoever sits in the district, interrupting the Mainline Phase on the
    turn the train arrives. Declining is an ordinary arrival onto an A/D track.
  - REACHABILITY is the engine's own move walk. `exploreMoves` already means what
    the card means — any distance without changing direction, finishing on
    Operational Rail (§2.4, §A.1) — so using it is what makes code and card agree.
    Reversing is a separate Move, so a yard that can only be reached by backing up
    is correctly out of reach.
  - CARS ON THE LEAD COLLIDE. The walk does not treat standing cars as obstacles;
    it COUPLES them, because that is what a switching move does. An arriving train
    is not switching, so what it would have coupled is what it is about to hit —
    the same reading §8.3 already applies to the Running Track. `destination.couples`
    is therefore the fouling signal, and it needed no new machinery.

Per Jesse's ruling (2026-08-29) the two failures his issue names are kept apart: no
route means no offer, with the history saying why ("make sure this is logged in
history — why can't move so user knows why they can't get to yard"); a route that
exists but is fouled IS offered, and taking it crashes. A silent absence is
indistinguishable from a broken feature, which is how the missing check survived.

THE SHARED REFACTOR THIS NEEDED. `pendingDecision` was one question asked of one
player — §8.1's clearance, always the Superintendent — and `currentActor` hardcoded
that. It is a discriminated union now, with `decisionActor` as the single place that
maps a question to whoever must answer it, and `clearanceRuling` generalised to
`decisionAnswer`. Six copies of `pendingDecision !== null ? superintendent :
currentActor` across the engine, the sim, the web client and the tests collapse into
`actingPlayer`; they had already stopped being right the moment a second kind of
question existed. Gitea#19 needs the same machinery and now only has to add a case.

A BUG THE FIRST CUT WALKED INTO, worth recording because it is a trap the next
interruption will meet too: the offer must be put BEFORE the train is taken off its
Mainline card. `needsClearance` unwinds the whole phase and the driver re-enters
from the top, so asking after the `transits` filter cost the train its place on the
card and the answer had nowhere to land. §8.1 gets this right by asking before it
commits, and the Yard Office now does the same.

The developer bot declines: the Yard Office frees an A/D track, but the lead may be
fouled and the bot cannot read its own yard well enough to tell (`TODO.md`, Bot
Performance). Declining is always safe and keeps the harness comparable with every
measurement taken before this rule existed.

851 tests pass.

Jesse.MarkowitzandClaude Opus 5 5e34c73b16 Extras that must run loaded, and a circus paid per district (Gitea#13)
"I've redefined some of the extra trains that they have to run full boxcars —
military trains, circus trains, etc. If not loaded, then empty, and if none
available, run without."

MAKE-UP. X17 Campaign, X18 Circus and X19 Military carry `mustRunLoaded`. It is a
preference order rather than a flat requirement, 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 accept, and once it cannot, the empty is legal and the train
may still depart short. Per category, since that is the slot the car competes for
— a loaded coach is no reason to refuse an empty boxcar.

SCORING, per Jesse's ruling (2026-08-29): "once per stop in an office area. In a
multiplayer game, each player could score if the circus stops in their area." So
`stopPointClaimed` (a boolean, once per game) becomes `stopPointSeats` (the seats
already paid). A Circus touring three districts is paid three times; one parked in
the same district all game is paid once. The other half of the ruling — "if the
circus train gets recycled and played a second time as a second extra, then it
could again score points later too" — needs no code: a train is made up onto a
fresh tray every time, so a re-played Extra starts with an empty list.

The point now requires the train to be FULLY LOADED, meaning every non-caboose car
loaded. A coach counts as loaded when occupied, which is what makes this the right
test for the Campaign Train: X17 carries one coach and no freight, so "fully
loaded" is exactly "the candidate is aboard". X17 also GAINS the per-stop point —
it had `stopThenExpedite` and no scoring rule at all, and Jesse's "credit for a
circus or campaign train (one point per stop)" says it should score.

TWO BUGS FIXED ALONG THE WAY:

  - `ConsistSpec.emptiesOnly` was declared on X13 Appleseed, RENDERED to the player
    as "(empties only)" by both web/game.ts and sim/view.ts, and enforced by
    nothing — `acceptsCar` never read it, so the Appleseed could be made up loaded
    while its own card said otherwise. It is the same rule as this issue pointing
    the other way, and it would have been perverse to add one and leave the other.
  - Setting up out on the Mainline paid a point to PLAYER 0 whoever was playing:
    `playerAtSeat` needs a seat, off the grid there is none, and the fallback was
    `0`. Scoping the rule to Office Areas is what the ruling says and removes the
    misattribution rather than patching it.

Both loading rules exempt the caboose: every caboose in ROLLING_STOCK_SUPPLY is
minted loaded, so an unexempted rule would bar the one car a consist lists by name.

`trainNeedingCars` now asks the full question per car rather than the shape
question. It shares its predicate with `check` precisely to avoid the stall its own
comment describes, and the shape question stopped being the same question: an
empties-only train facing a yard of loaded cars would have been told a car was
available and then refused every one.

The two published replays that stopped replaying under the new rules were retired
and re-recorded with save-replay.ts, which verifies each candidate before writing
it. That is what test/harness.test.ts is for and what its comment prescribes.

846 tests pass.

Jesse.MarkowitzandClaude Opus 5 45580d8b61 v0.7.3 — a game that asks before it ends, and a results screen worth reading
Two issues off the tracker, and they are halves of one thing: the end of a game.
Neither ships on the 0.4.9 line — Jesse's call, that line may be complete and
these are not fixes people mid-playtest need.

EXTENDED PLAY (#11). 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. Only days-based endings offer it; a §3.4
collision breach is final, during an extended Day exactly as during the scheduled
game.

It could not be a client-side change. `check` refused every intent once `status`
left `active`; the server 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. Hence a fourth status,
`awaitingExtension`, and a `game.extend` intent. `config.days` never moves —
`extraDays` counts the borrowed Days and `official` freezes the outcome, the
standings and the statistics at the first ending.

THE RESULTS SCREEN (#16). `GAME OVER — revenueFloor` was `outcome.reason`, an
internal enum interpolated 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. Around it: the result and winner, standings, the rules the game
was dealt under, a per-player breakdown, and the railroad — trains through the
Division and how many worked en route, loads made up and broken, passengers, cars
switched, trains destroyed. It shares the Day-end dialog's blocks rather than
reimplementing them, and stays reopenable so continuing does not cost you the
results.

Statistics are folded, not recorded: `state.tally` counts what the event stream
says happened, hooked at `applyIntent` and `advance` because `reduce` never sees
the phase driver's events — and those are the interesting ones. Nothing in the
rules reads it, and it rides the Frame, so multiplayer gets the same numbers as
solitaire from one implementation.

THREE BUGS FOUND IN TESTING, all of which would have shipped:

  - a saved game containing a vote could not be resumed (NO_ACTOR). A history is
    a flat Intent[] with no seat recorded; the replay derives who acted from the
    turn order, which cannot work for an intent every seat may send in any order.
    `game.extend` carries its voter, checked against the authenticated seat.
  - an all-bot game hung on the question for ever. `driveBots` loops on
    `currentActor`, null the moment the game stops, so it cannot cast a vote, and
    the bot-vote driver returned early with no humans to follow.
  - the balance harness became unbounded — `test/sim.test.ts` went from under a
    second to never finishing. `randomBot` took another Day about half the time,
    so every seeded game ran to playGame's 50,000-turn cap. Fixed in the driver,
    not in a policy, so it holds for bots not yet written.

All three have regression tests. 832 tests pass, against 793 before this change.

NOT BUILT, and a correction. #16's own comment said `trainStoodStill` "is emitted
per Stage, so a run of them is exactly the sat-on-a-siding streak". It is not:
reading advance.ts, it fires once per game and only for a train whose profile
sets `stopEarnsPoint` — the X18 Circus — with `stopPointClaimed` preventing a
second. The streak was built, rendered "1 Stage at (0,0)", and was taken out
again. There is no per-Stage "this train did not move" signal in the engine, so
"longest an engine sat on a siding" needs one first; TODO.md #36 records what it
would take, and the Circus set-up is reported instead. Badges remain the second
pass #16 asks for (TODO.md #33), and because the statistics are derived rather
than recorded, that pass can add any of them retroactively to games already
played and saved.

Extended play has not yet been played at a real table (TODO.md #35): the
multiplayer vote has only been driven through `session.intent`, never through two
browsers.

Jesse.Markowitz 2ab25e320c v0.7.2 — a leg that is part of the row, the deck the sheet prints, regions not miles per hour, and a Division you read left to right
Gitea#17 — a 45° leg is an end of the west-to-east row, so backing into a cut
through a curve's south leg no longer couples it back to front. The same
assumption left a crew's own cut standing when it pulled out through a leg,
which is the "cars left behind" report we had failed to reproduce.

Gitea#14 — every count is docs/Deck cards5.xlsx. Track halved, and the Q12
office doubling and Gap 12 industry tripling both come out with it: they were
measured against a deck with twice the track, and keeping them at the sheet's
track count wipes out the reefer chain entirely. 84 rows now match card for
card; the ten Safety, Event and Inspection cards it adds are not built and are
held out. Cards the sheet no longer lists are dealt zero copies rather than
deleted, so their rules stay implemented.

Gitea#15 — RAR reversed it: a rail may stop dead against its neighbour and the
placement is legal. What must hold is that no train crosses the gap, which was
already true and is now pinned against the reported board.

Gitea#3 — the printed speeds are scenery. A card costs one Stage per printed
region and where a train STARTS is what varies; Fast/Slow is read on Hilly
alone. Entering a one-region card behind another is a collision now, which is
what ABS exists to prevent, and ABS no longer holds trains silently.

Gitea#18 — the Division draws as one row, west to east, with no office-area
detail. East is finally always to the right.

Jesse.MarkowitzandClaude Opus 5 441447648d v0.7.1 — a caboose is not a load, a Day that says it ended, and a train you may throw away
Four issues off the Gitea tracker, all of them things a player saw at the board. Reasoning for
every item, and what was verified how: CHANGELOG.md.

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

The same four ship as v0.4.9g on the playtest line.

Jesse.MarkowitzandClaude Opus 5 06db36e5b5 v0.7.0 — four game types, a lobby you can read and leave, and a multiplayer game that makes a sound
The multiplayer set-up, the lobby, the start of a game, and four signals a remote client had never
been sent. Reasoning, the preset table and what was verified how: CHANGELOG.md.

- Co-op, Competitive, Cutthroat, Solitaire and Custom, on both screens, from one shared block —
  they had drifted, and each was missing a question the other asked.
- A player reads the whole rule set before taking a seat, may leave a lobby or a running game, and
  keeps a seat across a reload. The host may clear a chair. The browser remembers every game it is
  in, not just the last one.
- The start of a game is drawn: a handoff beat, an announcement, the code and type in the header.
- Sound, the timetable flash, announcements and the just-drawn badge now reach a remote client;
  justDrawn goes to the seat that drew it and nobody else.
- Played on StartOS, which found the rest: an Extra belongs to the player who played it, the board
  never named the Superintendent, bot seats were reported as absent players, and rule section
  numbers are out of every string a player reads.

Also carries the previous session's Heavy Grade documentation work — asked again, answer unchanged.

Jesse.Markowitz 7804756f11 v0.6.2 — an Extra starts where you put it, a train card is never discarded
Three more from the v0.4.9e gameplay-testing round, filed as Gitea issues, plus two bugs found
underneath them. Gitea#2 is diagnosed but NOT fixed: it needs a ruling, and the reasoning is in
TODO.md under Play Balance.

GITEA#4 — AN EXTRA STARTS WHERE THE PLAYER PUTS IT. Only one Division Point was ever offered,
chosen by number parity. The number no longer decides an Extra's direction — the start does, which
supersedes the recorded ruling that "the number decides, like everything else on the timetable".
The two cannot both hold: an odd, westbound Extra placed at the WEST end would leave the Division
on its first move having crossed nothing, and be paid for the run. Either end now runs the train
away from itself; at an Interchange or a Control Point the player picks the direction. The
Interchange start is a YARD, off the running line, which is what makes the Superintendent clause
work: placing it can never force a collision, a guaranteed one holds it there for another Stage,
and a potential one is the Superintendent's to rule on — exactly evaluateClearance's `blocked` and
`ask`, so nothing new decides collisions. Where an Extra may start is now a house rule
(divisionPointsOnly / ownOffice / anyOffice, defaulting to what the engine already did). The
legacy `atSeat` intent field still replays as it always meant.

FOUND UNDERNEATH IT: an Extra started away from a Division Point ran empty. isBeingMadeUp tested
position alone, so the Control Point start has been shipping since it was added with a train that
could never be given a consist. Found by playing it, not by the tests, which had only asserted
where the tray landed.

FOUND UNDERNEATH IT: collide left the wrecks on the card. Destroyed trains kept their Transit
entries, and evaluateClearance counts every transit as an occupant, so one rear-end collision
permanently poisoned that Mainline card for every later train.

THE MAINLINE CARDS WERE ROLLED, NOT DEALT — drawn from the nine types with replacement, so a
Division could hold two Interchanges and Plains carried the weight of a card printed once. "An
Extra may start at the Interchange if one is on the board" only reads as a rule if the board holds
at most one. Now dealt from the printed deck without replacement, verified over 1600 deals. This
re-deals every seed: the published replays were re-recorded, and the saved games in docs/ are
retired too — two of those were already dead before this release and nobody had noticed.

GITEA#6 — A TRAIN CARD IS NEVER DISCARDED, Timetabled and Extra alike. The forced play needed no
mechanism: nothing discardable plus a hand over the limit leaves exactly one legal way to end the
turn, and playing a train is unconditionally legal, so the corner cannot trap anyone. The bot
needed no rule either. 400/400 games finished, revenue unmoved, trains scheduled 1.2 -> 1.3. The
player is told on the card and on the button.

GITEA#7 — COACH COUNTS. 1/2 Crack Limited 3 -> 2, 5/6 The Sparrow 2 -> 3. A change to the cards,
so Trains3.pdf and the transcription keep the original numbers with a footnote while content.ts
and the Home Deck reference carry what the game plays.

CONTENT.TS COMMENT PASS — no data changed, only comments. Four were factually wrong, including an
office table naming counts doubled long ago and a pointer to a DEALT_DECK_SIZE that has never
existed. Every Enhancement row cited its implementation by line number and every citation had
rotted; they name functions now. Card counts came out of the comments, since they move with play
balance; source-sheet figures and dated measurements stayed.

TODO.md gains an item for a card reference generated from content.ts, in six sections, so the
documentation cannot disagree with the game.

715 tests pass, tsc clean, site builds.

Jesse.MarkowitzandClaude Opus 5 83a5450866 v0.6.1 — five of six playtest bugs: one button per train, and a load that has to go somewhere
Gameplay testing on 0.4.9d returned six reports. Five are fixed; the sixth could not be
reproduced and is written up in TODO.md with the two questions that would pin it down.

TWO TRAINS AT ONE PLATFORM ANSWERED TO ONE BUTTON. `porter.board` and `porter.detrain`
carried no tray, so there was one button per platform however many trains stood at it and
the reducer filled the first empty coach on the A/D tracks. `check` and the reducer were not
even asking the same question: `check` skipped a train whose card refuses passenger work and
the reducer did not. Both intents now carry an optional `trayId`, one function resolves the
train and the coach for check/execute/reduce alike, `legal.ts` offers one candidate per train,
and the label names it.

A LOAD COULD BE MADE AND BROKEN WITHOUT GOING ANYWHERE. A Freight House could unload the
boxcar it had just loaded; a platform could detrain the passengers it had just boarded. Full
Revenue at both ends for a movement that never happened. Jesse's rule: a load made anywhere in
an Office Area may not be broken anywhere in that Office Area, ever — it has to be carried to
another district. The load carries the seat that made it (`RollingStock.origin`), stripped by
`pooled` at every yard push. Measured at -0.60 +/- 0.10 Revenue a game (t = -6.1) over 400
paired deals: 78 worse, 3 better, 319 unchanged — free Revenue coming off the board, not a nerf.

THE GROCER'S WAREHOUSE SHIPPED AND THE REFINERY RECEIVED. Both were `flow: 'both'` on the
reading that "Freight House" was a collective term for exactly those two, and therefore what
§9.3 described. The engine has dealt a Freight House CARD since before v0.4.9, so §9.3 names
it and the argument goes. The card set agrees: all three Refinery modifiers grant +1 outbound.
Refinery outbound-only, Grocer's inbound-only, Freight House the one two-way industry — which
leaves exactly the one same-district pairing the rule above refuses.

NOT REPRODUCED: cars left behind when backing up over them. Five layouts tried, including cars
spotted at an industry; every one couples the lot. Three are pinned in `apply.test.ts`. One way
to create such cars was closed anyway — `flyingSwitch` wrote its cut past `carsOn`.

Both published replays that had gone dead were re-recorded; a rules change retires a save, and
`harness.test.ts` is what catches it.

The same change ships as v0.4.9e on the 0.4.9 line, branched from the v0.4.9d commit — the engine
files these fixes touch are identical across the two lines, so the patch applied cleanly both ways.

Also carries the two "Queued 2026-08-22, from playing on StartOS" TODO items that were staged
before this work started (Games in Progress readability, and getting back into a game after
losing a browser). They are notes, and items 9-12 below them are numbered against them.

Jesse.Markowitz 40f07b0710 v0.6.0 — saves survive a release, Employee Rotation is real, and the lobby
asks what game you want

Three queued items. The last matters most.

A RELEASE NO LONGER DESTROYS EVERY GAME IN PROGRESS.

Four consecutive releases killed every game on the box, one of them a
release that changed only how the board is drawn. The reasoning behind the
refusal was always right — a move legal under old rules may not be legal
under new ones, and half-replaying a save is worse than refusing it. The
TEST was wrong: it compared engineVersion for exact equality, and that
stamp is the package version, which moves for a CSS fix.

Whether a save still replays has an exact answer, so it is now asked
directly. loadGame reads the file and judges nothing; tryResumeSession
replays the intents and reports the first one the engine refuses. A save
stamped with a version this server has never run resumes fine provided its
moves replay — verified against a file hand-stamped 0.4.9-ancient. One that
genuinely does not replay is still refused, but the log names the move
rather than two version strings: "move 3 of 8 (localOps.choose) is rejected
by the current rules with OPTION_ALREADY_CHOSEN".

fromMultiplayerSave had to stop lying first. It has always stopped at the
first unacceptable intent and done so in silence, which was survivable only
because the version gate meant a doomed replay was never attempted. Now
that the replay IS the check, it returns where it stopped and why.

Deliberately not done: resuming a partly-replayable game at its last good
move. That silently rewinds a game to a position nobody played to while
every browser holding a later Frame carries on unaware. Refusing leaves the
file intact, so putting the previous version back still recovers it.

EMPLOYEE ROTATION IS IMPLEMENTED, SISTER TRAINS IS DELETED.

Two of the four optional-rule flags were read by nothing at all. Employee
Rotation is four lines in advance.ts, because the seat/player split (D9)
exists for precisely this rule: seating is the only thing that moves, so
Revenue, hands, the Superintendent and whose turn it is travel with the
player, and the Office, district, grid and any trains standing in it stay
with the chair. Inheriting the district you move into is the point of the
rule, not a side effect. "Left" is seat + 1, matching playerLeftOf.

Sister Trains is deleted rather than built: Q9 records that the Second
Section card supersedes it, and that card exists, so the flag was a toggle
for a rule the game no longer has.

THE LOBBY ASKS WHAT GAME YOU WANT TO PLAY.

Creating a game asked for a name, a mode and a table size; every other dial
was hardcoded. A Game settings block now carries the same set the solitaire
dialog does — seed, starting hand, the three revenue rates, Days, the
combined-Revenue floor, both collision caps, the opponent-card toggle —
plus the three surviving optional rules. Mode and table size set the
defaults and everything stays editable. The seed is honoured, so a game can
be reproduced or compared.

Verified: 682 tests pass (679 + 3). The rotation tests were mutation-checked
both ways — disabling the rotation and turning the table the wrong way each
fail the suite. Live: a save stamped 0.4.9-ancient resumed, an injected
illegal move was refused by name, and a create with every dial set to a
non-default value came back out of game.json with all of them intact,
including seed 777.

Two of my own assertions were wrong on the way and the tests caught them:
the Fedora legitimately passes at Stage 12 (§5) so it cannot be compared
against its own earlier value, and dispatchUsedToday is cleared at every
Day boundary so it cannot mark a district.
2026-08-21 21:45:34 -04:00
Jesse 51710498f5 v0.5.6 — seats counted from 1, a name you can read, and a line that stops repeating
Three things off the first proper look at a live table.

The lobby listed chairs as Seat 0 to Seat 3. Zero-based is right inside —
it indexes seating, the seats array and every route, and none of that
changes — but nobody sitting at a table calls their chair "seat 0". There
were four of these rather than one: the lobby list, the topline's Seat N
for a remote session, the presence banner's fallback name, and the admin
summary's. All go through a single seatLabel now, and a test fails the
build if any "Seat ${...}" interpolates a raw seat again, since the
conversion has to happen in exactly one place or the two conventions drift
apart. Verified by mutation — putting the raw seat back fails the suite.

seatLabel lives in sim/view.ts, not web/game.ts. Putting it in game.ts was
the first attempt and test/session.test.ts caught it: the page may not
import values from that module, because they are the local engine by
another name and importing one reopens the Phase 1 boundary. The test was
right and the placement was wrong.

.bs-name.bs-turn carried font-weight:700 over a base of 600. At 11px a
monospace face has to be synthesised the rest of the way and the extra ink
lands as blur, so the one name you most need to read was the one you could
not. The bump is gone; amber against #e6e9ee was always doing the work, and
blue "(you)" and amber "their move" stay clearly distinct without it.

The west-to-east chain under the Division map now shows only during Day 1
Stage 1. It answers who is where and why, which is a question you have once
— at the start, when the chain has just been rolled and the names are new.
By Stage 2 the map has been answering it for a while and the line is
something to read past.

675 tests pass (673 + 2).
2026-08-21 20:53:17 -04:00
Jesse 689de2ff0f v0.5.4 — the map says whose railroad is whose
Six things found playing the StartOS build, all of them the game telling
you what it already knew.

The lobby's Start button did not look disabled when it was. The reported
symptom was "it says it's waiting for a player but Start is enabled" — it
wasn't: the note and the disabled assignment are two lines apart in the
same block. The page had only `header button:disabled` and `#actions
button:disabled`, and #lb-start is in neither, so a disabled button kept
its normal face AND still lit up under the cursor from the generic
button:hover. It advertised a click it would refuse. The rule is generic
now.

The game code was rendered as "— code TRESTLE-5109" in dim text beside a
heading, reading like a reference number rather than the thing you have to
send somebody. It is a labelled block at 22px with a Copy button, and a
clipboard refusal says the code can be selected instead of failing
silently. The blurb under it was also WRONG — it claimed the chairs were
"in the order everyone joined", which stopped being true in v0.4.1 when the
§4.4 D12 started deciding. It now says what actually happens.

Every Office on the Division map was labelled with its tier, which every
other player's Office also has, so four districts read identically and
"where does Bob sit" had no answer on the one map showing where trains are.
The owner's name takes the headline and the tier moves beside the A/D
count. Amber marks whose move it is — the same "happening here" the action
panel uses — and "(you)" is spelled out on the reader's own district,
because colour alone cannot say which of four railroads is yours. Turn
colour wins over the you-colour when both apply: whose turn it is changes
every few seconds, which railroad is yours never does.

Under the map, the chain in words with the roll behind it: "West to East:
Alice (1) → Bot 2 (5) → Bot 1 (11)". state.openingRolls has been kept for
exactly this since v0.4.1 and nothing had displayed it. It also answers
"is the host always at the eastern end" outright — no. Alice there is the
host, rolled lowest, and sits at the western end.

Supporting: Frame gained viewer and viewerSeat. Every private field on it
was already scoped to one player, but nothing said which player, so a page
could draw a railroad without being able to say whose it was — harmless in
solitaire, the first question at four seats. Frame also gained
openingRolls. Bots are Bot 1 / Bot 2 rather than all Bot, since two of them
are two different railroads. The standalone replay gets all of it: players,
actor and viewer are not delta'd keys in compress, so they ride whole on
every frame and replay.ts passes the same roster.

Verified: 673 tests pass (668 + 5). The new ones were mutation-checked —
removing the (you) suffix, never applying the turn mark, and reinstating
the pre-v0.4.1 identity seating each fail the suite. The seating test
deliberately asserts across six seeds that the eastern end is NOT always
player 0, which is the claim it exists to defend.
2026-08-21 17:12:25 -04:00
Jesse 2fbfe11977 v0.5.3 — a table you size yourself, and games an administrator can see and end
Both halves came out of playing the StartOS build. The wrapper's health
check and admin actions consume this; they land separately.

The host picks the table size (2-4) when creating a game, and the seats
array is built at that length once. Before, it GREW as people joined, so
the four rows on screen were partly fiction — a 2-player game just started
with a 2-long array, while a host who dropped a bot into a later chair
padded it with a null and silently disabled Start behind a one-line note.
A gap can no longer be written down rather than merely being refused.

That also avoided a trap. Compacting seats at Lobby.Start — the obvious
way to support a "closed" chair — would have shifted the player index that
every PlayerSession stamps at join time and that /api/stream and
/api/intent both route by, handing a player somebody else's railroad with
no error anywhere.

And it fixed a live balance bug: minCombinedRevenue is derived from the
player count, but the config was fixed at CREATE while the count wasn't
known until START, so the lobby guessed 4. Every 2-player game ran against
a floor of 60 instead of 30 — and missing the floor means everyone loses,
so a 2-player competitive game was set up to fail for a UI artifact rather
than a rule.

/api/health gained games:{active,lobby}, read from a new cheap summary()
on GameSession rather than exportSave(), which would copy every intent of
every game to answer a question about none of them. Three admin routes are
new behind an ADMIN_SECRET env var in an x-admin-secret header: GET
/api/games, GET /api/games/<id>/save, DELETE /api/games/<id>. Until now a
started game could not be ended by anyone — no route, no player action, no
resignation — so an abandoned game stayed active in the index and was
faithfully resumed on every boot, forever.

Three deliberate choices there: the admin secret is NOT the join secret,
which every player holds and which would therefore let anyone at the table
destroy anyone else's game; unset means the routes 404 exactly as any
unknown path does, with or without a header, so a server never given an
administrator doesn't advertise that it has one; and a delete returns the
deleted game's save, since the intents are the game (D5) — nothing is
destroyed without being handed to whoever destroyed it.

SavedGame gained an optional lastMoveAt (falling back to createdAt) so
"has this stalled?" survives a restart. Kept out of history for the same
reason the turn timings are: a replay must reproduce a game from decisions
alone, and wall-clock is not a decision.

index.ts logs "Resuming N saved games..." before the loop rather than one
line per game after it. Measured a full 4-player game at 100ms to replay,
and only unfinished games are replayed, so listening before loading would
have bought nothing for the cost of a "still loading" state everywhere.

Verified: 667 tests pass (662 + 5), and the new session tests were checked
against two mutations (lastMoveAt never advancing; resume dropping it) to
confirm they fail without the code. Live against a running server: health
counts tracking through the lobby->game transition, admin auth rejecting a
missing and a wrong secret, list/export/delete, the deleted game's files
and index entry actually gone from disk, a second delete 404ing, the admin
routes invisible when ADMIN_SECRET is unset, and a 3-player table refusing
a 4th player and a size of 5 refused at the door.

Also carries the TODO items raised on 2026-08-21: the lobby offering no
game parameters (the floor bug within it now fixed, the form still
missing), and the four optionalRules — of which only reducedVisibility and
emergencyToolbox are read by anything, while sisterTrains and
employeeRotation are declared, defaulted, and consulted nowhere.
2026-08-21 14:53:53 -04:00
Jesse 62b6ed7e1b v0.5.2 — the splash's multiplayer door opens, and knows whether it should
The "Play multiplayer" door on index.html had sat disabled, labelled
"Coming soon", since before the server existed — Phases 2 through 4 built
a working lobby and nothing ever linked to it. Loading the site landed on
the same solitaire splash whether a real multiplayer server was behind it
or not, with no visible way in. Found packaging Phase 6 for StartOS.

The door is now a live link to ./play.html?lobby, and main.ts's start()
routes ?lobby straight to the lobby screen — the same showScreen('lobby');
runLobby(beginRemote) the in-game Multiplayer button already used —
instead of dealing a solitaire game first.

GET /api/health is new, and exists to be failed. The same dist/ ships both
served by src/server/ and uploaded as flat files by deploy-web.ts, and the
bundle is identical either way (D4), so the page cannot know from its own
build which it is; every other route 404s an unknown path exactly as a
static host does, so nothing distinguished them. The splash probes it on
load and closes the door when nothing names itself in reply.

The door starts open and only ever closes, deliberately: a wrong "no
server" is the bug above again — invisible, and it strands a player who
does have one — while a wrong "there is one" costs a click and a lobby
that says it cannot connect. The reply must name itself rather than merely
return 200, or a host answering every path with its index page would pass.

Verified: tsc clean; 659 tests pass (656 + 3); /api/health exercised live
against a running server — 200 with the right body, unauthenticated, while
an unknown path and a wrong method both still 404, which is what makes the
probe discriminate at all.

The probe's own test was vacuous on the first attempt — both its "closes"
cases reached close() through the .catch arm, so deleting the body-naming
check outright still passed. Caught by mutating splash.ts and re-running;
the test now covers all three closing routes and fails without the check.
2026-08-21 11:00:06 -04:00
Jesse e76bd77099 v0.5.1 — multiplayer Phase 4: lobby, sessions, reconnection
A real server existed since v0.5.0 but nobody could reach it without a hand-built ?seat=&secret=
URL. This is what makes it a game you can actually create or join.

The server now hosts more than one game: src/server/lobby.ts (new) is pure logic — creating,
joining, bot seats, host transfer, starting — same split session.ts already draws for a running
game. persistence.ts gained one directory per gameId plus a top-level index so index.ts resumes
every saved game on boot. /api/stream and /api/intent now authenticate by session token instead of
?seat=&secret= — the token alone proves identity (lobby-and-sessions.md §1), so the join secret's
job ends at the lobby door.

Bots fill empty seats at Lobby.Start only, never take over a disconnected human (D8): session.ts
gained driveBots(), playing developerBot forward through consecutive bot seats after every accepted
intent. Disconnect keeps the seat and says so — Push gained an optional presence field, built
entirely by http.ts and never routed through the engine, since a disconnect is transport news, not
a GameEvent. Host rights pass to the earliest-joined remaining player if the host drops before
start.

Client: src/web/lobby.ts adds create/join forms and a live seating screen; localStorage replaces
?seat= for reconnecting straight back into a game already joined. A Multiplayer button sits beside
New game; the New Game dialog itself is untouched.

Found only by the live smoke test, not by typechecking: /api/intent read its token from the JSON
body while the client sends it in the query string (matching /api/stream) — every intent failed
"no such game" until caught by curl-level verification.

Doc fix: multiplayer.md's D18 said the player cap was 6; lobby-and-sessions.md §2 says 2-4 with the
reasoning and the test coverage to back it. The two had drifted apart. D18 now reads 2-4.

Not verified: an actual browser walking through the lobby screens — none available in this
environment, same limitation Phase 2's RemoteSession shipped under. 656 tests, 0 failures.

2026-08-21 05:25:47 -04:00
Jesse c3c5cbfeec v0.5.0 — multiplayer Phases 2 and 3: a server that runs a game and survives being restarted
Phases 0-1 shipped in v0.4.0 (seat/identity split, per-player turn state, the Session boundary).
This lands Phase 2 (server core, one game, no lobby) and Phase 3 (persistence and resumption) per
docs/architecture/multiplayer.md §12. Phases 4-6 (lobby/reconnection, the 22 opponent-directed
cards, StartOS packaging) are still ahead.

Phase 2: src/server/session.ts hosts a game in pure logic (no sockets) on top of game.ts's existing
Game/submit/currentActor/actionMenu; it verifies seat === currentActor(game) itself before calling
submit, since submit() trusts its caller and a server can't. src/server/http.ts and index.ts add
POST /api/game, GET /api/stream (SSE, per-seat), POST /api/intent, and static serving of dist/.
src/sim/frame-delta.ts is a purpose-built per-seat board delta for one live push at a time. Found
and fixed along the way: actionMenu(game, seat) only used seat for the hand field, so a server
computing every connected seat's Menu would have handed the acting player's legal moves to a
waiting seat. Verified with a live end-to-end smoke test (2-player game, two SSE streams, a
rejected intent from the wrong seat, an idempotent resend) plus test/server/session.test.ts and
test/redaction.test.ts. Not verified: an actual browser (none available in this environment).

Phase 3: src/server/persistence.ts writes game.json and turn-timings.json, atomic-rewrite-then-
rename. game.ts gained fromMultiplayerSave, fixing a narration-attribution bug found while testing
it (fromSave's replay loop drops the actor argument, invisible in solitaire, unreadable the moment
there's more than one seat — fromSave itself still has this gap, deliberately untouched). Verified
live: server killed and restarted mid-game, both seats reconnected exactly where they left off.

Two rules bugs found while building this: the New Train phase never implemented its car-placement
round (every car of every train was placed by the Superintendent alone, in every mode, all along —
now reads the round position off tray.consist.length); and victory conditions are now one shared,
configurable GameConfig set across solitaire/competitive/coop instead of a fixed length lookup and
a dead firstToTarget condition.

Also folds in the three fixes already released on the patch line as v0.4.9b/c/d: a switching
train's crew badge failing to draw once it left the Office square, an unload that always took the
westmost car regardless of which was picked, and a legal decision that could render with zero
buttons.

Jesse f9c4d9fa92 v0.4.9d — three playtest bugs: a train that looked gone, an unload that ignored the pick, a hang that wasn't one
Patched directly onto 0.4.9a rather than the in-progress 0.5.0 line.

A switching train vanished from the board the moment it left the Office. `selectedTrain` in
`officeSvg` (board-svg.ts), which gates whether a card draws a train's crew badge, was only ever
assigned inside the `cell.adTracks !== null` branch — true for the Office card alone. A train
standing anywhere else, which is everywhere it stands while actually being switched, drew no badge
at all. Game state was never affected; confirmed against the reported save with the engine directly.
Fix hoists the assignment out of the guard so it runs for any card with a train on it.

Unloading always took the westmost car, whichever one was picked. `laborer.beginUnload` carried the
player's chosen `carIndex`, and `check()` validated that specific car, but the `unloadBegan` event
it produced carried only the car's type — the reducer that performs the swap re-derived the target
with `industryTrack.cars.findIndex(c => c.loaded)`, which always answers the first loaded car in
track order regardless of what was requested. Fix adds `carIndex` to the event and uses it directly.

A legal decision could render with zero buttons, which looked exactly like a hang. The "where does
this Extra start" decision is titled by `trainCardTitle`, beginning "Making up Extra X22…" — the
same prefix `renderActions()` stripped from the action list on the assumption it only ever belonged
to the separate yard-chip car-placement panel. With no tray yet being filled, that panel is null, so
nothing rendered the Extra's decision either: a legal, correctly-computed option with no button
anywhere on the page. Replaying the reported save found no engine deadlock at any step — the engine
always had a move. Fix matches the exact title of the one group the yard-chip panel covers instead
of a title-prefix regex.

New tests for all three: a train parked on an ordinary facility card must draw its crew badge; three
differently-typed loaded cars, unloading index 2, must leave indices 0 and 1 alone; the existing
softlock regression test now mirrors the real render filter instead of only the raw menu, plus a
deterministic test for the exact reported scenario. 590 tests, 0 failures.
