Jesse.MarkowitzandClaude Opus 5 3befc420da v0.8.2 — every district opens on a Depot, and the docs are pages now
A second-digit bump for a playtest read back against the save file. Nine questions
were asked of one three-Day game; three were bugs, three were the rules working
and undocumented, three were decisions. Every save on the test server was replayed
against this build BEFORE release, which is how the cost of each rule was known
before it was chosen rather than discovered after.

EVERY DISTRICT OPENS ON A DEPOT. A Whistle Post has one A/D track and is not a
Passenger Facility, so the opening of every game was spent unable to work a
passenger and one arrival away from a collision. Two A/D tracks and passengers
from Stage 1 now; "Players start with Whistle Posts, not Depots" is the harder
game, set when the game is created. The deck follows the choice — starting on
Depots the four Depot upgrade cards are left out, because an upgrade must be to
the next tier and a Depot card at a table of Depots is a dead draw. How much
easier it is showed up as a test failure rather than an argument: the cue-coverage
pool needed widening from 24 seeded games to 60 before it held one collision.

NO SAVE WAS STRANDED BY IT, which took care. This is the one house rule that
changes how a game is DEALT rather than how it plays, so replaying a save under
the wrong opening is a different railroad from intent one — silently, with no
error. `withSavedOpening` fills it on the replay paths ONLY. Putting it in the
resolver instead made a fresh Cutthroat game deal Whistle Posts and read as
Custom, which is how the distinction was found.

THREE BUGS, ALL REPORTED FROM ONE GAME AND ALL CONFIRMED ON ITS SAVE.

An Office held TWO TRAINS ON ONE A/D TRACK. The capacity test passed with nothing
standing, the train the Interlocking had been holding at the Limits was moved into
the free slot, and the arriving train was pushed in after it without anyone asking
again whether there was room — so the collision §8.3 calls for never happened. The
held train keeps priority; the newcomer now takes the consequence it would have
met had the held train arrived first.

THE HISTORY FROZE, permanently, and the log cap was not really the cause. Each
seat's "what have I sent you" bookmark was an INDEX into an array the game trims,
so once a seat's bookmark reached the limit the slice returned nothing for the
rest of the game — at a different moment per seat, because each holds its own.
That game's log ended at exactly the cap. Lines carry a sequence number now, which
survives trimming; proven by pushing twice the cap through a simulated seat.

§8.1 ASKED THE WRONG QUESTION TWICE. "Trains may pass" returned `clear` before the
Subdivision was looked at, so a train entering a Double Track was released however
busy the rest of it was — that, not anything about Control Points, is what let
Train 8 out with no ruling. And a train standing at an Office was invisible to the
scan, so one about to re-enter the very Subdivision being entered counted for
nothing. Capacity is the test, not presence: a Depot with a track free is not in
the way; a Whistle Post with its one track taken is.

THINGS THAT HAPPENED SILENTLY NOW SAY SO — a train held against a facing one, a
train released from the Limits (a side effect of somebody else's arrival, so it
simply appeared at the Office), and the train an Interlocking is holding, whose
explanatory tooltip has existed since #99 with NO renderer ever reading the flag.

WHERE A MOVE IS REFUSED, AND WHY. `exploreMoves` decides where the rails go and the
pick-up restrictions are enforced afterwards in `check`, so a square the rails
reached and the card forbade was reachable, un-offered, and absent from the block
list with nothing said. Those squares are blocked with the rule that blocks them
now, and the reasons are got by ASKING `check` rather than re-deriving: a second
implementation of the rules is exactly the failure the block list exists to avoid.
A train may also always recover its own caboose — X13 prints "may drop but not
pick up anything", and a train needs its caboose to be made up, so one that parted
with it could never legally leave again.

RULES DECIDED IN SEPTEMBER AND APPLIED HERE. A Modifier must sit square against its
host, no diagonals. A passenger Modifier may not be played at a Whistle Post. Both
were built, measured, held back for a fortnight so a playtest could finish, and
applied now. A Second Section costs its card: `SECOND_SECTION` was declared in
content.ts and never dealt, so the action was free and the bot ordered 26
accidental ones in a measured round. The card is dealt and spent — gating on a card
the deck never holds would have deleted the mechanic rather than fixed it.

THE DOCUMENTATION IS A SET OF PAGES, not five text files served as text/plain — a
card reference is mostly tables, and as plain text a table is rows of pipes.
Markdown is still the one copy; the build renders it, and publishes the .md beside
each page. No Markdown library: this project has no runtime dependencies and one
would be a poor first. The pages add what Markdown cannot carry without drifting —
a nav across the set, a contents list built from the headings actually rendered,
an anchor on every heading, a 70-character measure, and tables that are tables.
They print as ink on paper.

The references caught up with the rules, checked rather than assumed: two
statements had gone from stale to misleading (the Quickstart told a new player to
"get a Depot down as soon as one appears"), and four rules nobody could look up
are written down — the Office tier table, §8.1 in practice, what the Circus Train
pays for, and that a Realignment can be a card with no legal target.

Adding one card to the deck reshuffles every seeded deal, which broke five
fixtures. Each was a seed meaning "a game like this" — TODO #84, exactly — so
seeds moved and pools widened rather than assertions weakening, and the clearance
fixture pins its terrain the way `enhancements.test.ts` already does. The three
published replays were re-recorded.

Closes TODO #40, #42a, #108, #109 and #110.

1046 fast tests and 35 sim tests pass.

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 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 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 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 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.

Closes #11
Closes #16

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.

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.

docs/testing/0.5.0-test-plan.md and three reported-bug save files (docs/station-master-seed*.json)
included for reproducibility. tools/jitsi-harness/ deliberately left untracked — unrelated
side-project work, not part of this release. 635 tests, 0 failures.
