docker exec defaults to root, so the systemd base-backup timer connected to the
database as role "root" (then "postgres") — neither exists; the superuser role is
POSTGRES_USER (scrabble). Run the timer's pgBackRest as the postgres OS user (-u postgres,
for lock-dir/PGDATA consistency with archive-push) and connect with --pg1-user=scrabble.
archive_command (run by the postgres server process) was already correct.
Also record the point-in-time-recovery arming + restore drill in deploy/README.md
(correct the runbook commands to the same invocation, fill the drill log) and mark the
durability work done in PLAN.md.
The S3 endpoint is a host only; some providers publish a separate, non-443
port. Add an optional PGBACKREST_S3_PORT (default 443) alongside the endpoint
host, wired through the prod overlay, write-prod-env.sh and both prod workflows,
and clarify in the docs that the endpoint variable takes the host alone.
Add pgBackRest-based PITR for the production database, shipped disarmed
(archive_mode and the base-backup timer gated off) so it stays inert until the
operator arms it before real payments — an un-armed deploy cannot pile WAL onto
the disk.
- Postgres now builds from a thin image carrying pgBackRest (archive_command runs
in-process); the prod overlay wires an encrypted (AES-256-CBC), path-style S3
repository with 30-day retention and a daily full base-backup systemd timer.
- Repository config/secrets flow through the PROD_PGBACKREST_* Gitea set and
write-prod-env.sh; prod-rollback re-renders the same env so a rollback cannot
disarm archiving.
- Grafana alerts watch pg_stat_archiver (failing / stalled), absent-safe on the
test contour, which never archives.
- Fix the pre-migration pg_dump to snapshot the whole database (was backend-only,
silently excluding payments).
- Document the PITR runbook, the arming sequence and the restore drill in
deploy/README.md; record the measured cost/perf assessment.
Add the "Кошелёк" section to the settings hub: context-visible chip
balances, active benefits (no-ads term/forever, hints) and a storefront of
chip-priced values and money-priced chip packs. Guests have no wallet; the
Google Play build hides the money purchases behind a RuStore stub; a web
purchase that would draw VK/Telegram chips warns first.
Add the catalog read path the storefront needs — a context-projected
GET /api/v1/user/wallet/catalog (payments service + store, gateway op
wallet.catalog, FBS Catalog/CatalogProduct/CatalogAtom, client decode) —
plus the client leg for the existing wallet.get/buy ops. Value spends reuse
the existing spend path; the chip-pack purchase (money order flow) arrives
with payment intake, so its action is a disabled placeholder for now.
Covered by Go unit (catalog projection) + integration (/wallet/catalog over
Postgres), vitest (formatting, spendable selection, web-spend warning, GP
flag, codec + gateway encode round-trips) and Playwright mock e2e (render,
guest-hidden, GP stub, warning) on Chromium + WebKit.
Stand up the internal chip/benefit mechanic behind the narrow payments interface:
context-aware balances and benefits, an atomic chip spend, admin grants as
zero-price value sales, the one-directional store-compliance gate (VK/TG same-
origin only, web draws direct→vk→tg, VK-iOS frozen, untrusted fail-closed), and
per-origin hint and no-ads application with term stacking. Reads are served from
an in-process, account-keyed write-through cache (mirroring the suspension gate),
so hot paths issue no query to the payments schema.
Flip the online-game hint wallet and the ad-banner suppression from the deprecated
accounts.hint_balance / paid_account columns to the payments benefit (a hint
balance no longer suppresses the banner — only a no-ads benefit does), and fold
chip segments and benefits by origin on account merge, inside the merge tx. Add
the GET/POST /api/v1/user/wallet edge chain (REST → Connect → FlatBuffers) plus
its codec unit test; no wallet UI yet.
Bring the frozen owner decisions log into the repo at
docs/PAYMENTS_DECISIONS_ru.md (it was untracked under .vscode) and reference it
from PLAN.md; record the read-cache design and the present-sources interface in
PLAN.md and docs/PAYMENTS.md (+ RU mirror).
Record the execution platform (kind vk|telegram|direct + device subtype
ios|android|web) on each session, captured at creation and carried
gateway->backend as a trusted X-Platform header, so the upcoming
store-compliance gate has an unforgeable execution context.
- backend.sessions gains nullable platform_kind/platform_subtype columns
(migration 00011, CHECK-constrained, jet regenerated); session.Platform
captures them at mint, resolve returns them, middleware exposes platform(c).
kind is derived from the establish endpoint, never a client field; the
account-merge session mint inherits the caller's platform.
- gateway derives the platform (VK subtype from the signed vk_platform via
vkauth, Telegram/direct best-effort from the client) and injects X-Platform
on every authenticated backend call through the request context.
- ui submits a best-effort device subtype on the telegram/guest/email login
requests (new FBS subtype field); VK is server-derived from the signed params.
- an unattributed session is untrusted (view-only); VK/TG self-heal on the next
cold-start re-mint, direct/email on re-login.
Signal plumbing only, no user-visible change; X-Platform is inert until the
gate consumes it.
The committed go-jet code had drifted from the schema: robot_blocks and
robot_friend_requests (created in the baseline) had no generated tables, the
feedback_messages model was missing app_version/browser_tz (added in 00003 and
00004), and UseSchema omitted account_best_move and the two robot tables.
Regenerate so the jet layer mirrors the migrations again.
Additive only — two nullable columns appended to feedback_messages plus two new
tables; the full build, vet, unit and integration suites stay green.
Stand up the payments data foundation: a self-contained `payments` Postgres
schema for the in-game currency, wallets, benefits, catalog, orders and the
append-only operations ledger, behind a domain package — nothing wired to real
money yet.
- Migration 00010: the `payments` schema and a NOLOGIN confinement role (ALL on
payments.*, nothing on backend); the ledger with a BEFORE UPDATE/DELETE
append-only trigger and a partial idempotency index; the materialised
balances/benefits; the catalog (atoms seeded) + products + per-method prices;
the typed single-row config; orders and payment_events. There is no
cross-schema foreign key — account_id is a plain uuid kept consistent in code,
which keeps the domain extractable. Expand-contract and reversible.
- Money is a bigint in the currency's minor units carried by a `Money` value
type (exact, math/big): no float ever touches an amount, and a whole-unit
currency cannot hold a fraction.
- Extend jetgen to generate the payments schema; construct the service in the
composition root behind a narrow interface with a boot reachability check.
- Tests: integration (role confinement via SET ROLE, the append-only trigger,
CHECK constraints, the idempotency index, and a forward+backward migration),
Money unit tests, and an import-boundary test keeping the payments jet code
private to the domain.
- Docs: PLAN.md, docs/PAYMENTS.md (+ _ru mirror) updated to the built model.
The deploy job gated only on the event/ref, so a docs-only PR into
development (where unit/integration/ui/conformance path-skip) still
redeployed the test contour for nothing. Gate it on the `changes` job
too: deploy only when the Go or UI side changed. `changes` still
defaults both true when the diff is uncomputable, and a workflow/deploy
edit forces both true, so ambiguous or infra changes still deploy.
The 2-4 hotseat players now start in a random seating order (so who goes
first, and the turn order, is random) — matching the online games. The
engine starts at seat 0, so shuffling the seats at creation picks the
starter; the shuffle is seed-driven (a distinct derivation from the tile
bag), so replay reproduces it. Scoped to hotseat — vs_ai stays human-first.
- lib/roster.ts: shuffleSeeded (unit-tested); NewGame shuffles buildSeats
with the game seed before create.
- e2e: pin a seed that keeps the roster order so the lock assertions stay
deterministic.
Bring the online lobby badge and the in-game 'you won/lost' text to the
same competition ranking the hotseat seat medals use: in a 3-4 player game
a TIE for the lead is a SHARED victory for the top scorers and a placed
finish for those below — not a full draw for everyone (winner() is -1 on
any tie, so isWinner alone conflated them). An aborted game and a genuine
all-level finish stay a draw; a win by resignation (winner at a not-higher
score) is unchanged.
- result.ts: resultBadge no-winner branch ranks by final score; placeBadge
helper; resigned seats excluded from the ranking.
- Game.svelte: resultText aligned (shared lead = won, below = lost).
Reported: a hotseat game ended by 6 scoreless passes deducts each rack
(correct rule, same as online: -8/-14/-8 here), which tied two seats for
the lead. The engine's winner() returns -1 on a tie, so seatMedal read it
as a full draw and gave EVERY seat the last-place medal.
- result.ts: seatMedal now ranks by the FINAL score (competition ranking —
a tie for the lead shares the trophy), not the single-winner flag. A
resigned / host-excluded seat places last with no medal and does not push
the others down.
- model.ts: Seat.resigned (offline-only); engine.resignedOf getter; the
local source surfaces it on the game view.
- The scoreless rack deduction is unchanged (standard rules, owner-confirmed).
Per owner: a vs_ai game (one human) keeps its 'you won/lost' status text
AND its lobby medal — the hidden-status + per-seat-medal treatment applies
only to hotseat, where 2-4 local players make a single 'you' meaningless.
isLocalGameId -> game.hotseat at the three call sites (statusBlock, seat
plaque, lobby card).
For a local (offline) game the outcome is not always about a single
'you' (hotseat is 2-4 players), so:
- Game.svelte: a finished local game no longer shows the viewer-centric
'you won/lost/draw' status; instead each seat plaque shows a per-seat
place medal, left of the name (result.seatMedal — trophy for the winner,
then places by score; a draw medals everyone).
- Lobby.svelte: a local game shows no lobby medal (resultBadge is
viewer-centric and no seat matches the account) — its result lives on
the in-game plaques.
- result.ts: seatMedal(game, seat), unit-tested.
- History drawer in a local (offline) game: the seat plaques no longer
show the add-friend/block controls — canAddFriend/canBlock now exclude a
local game (hotseat seats have synthetic account ids that slipped past
the vs_ai-only guard) — and the Dictionary entry is restored: an active
hotseat game keeps the comms button, and CommsHub is Dictionary-only for
a chatless vs_ai OR hotseat game (ChatScreen never mounts offline).
- Enter on any single-line <input> now dismisses the soft keyboard (blur);
a <textarea> (feedback) keeps Enter for newlines. One global handler.
- Login email code: the friend-code spread-digit style (.codein), a
6-char cap, auto-submit on the 6th digit, and Enter to submit.
- e2e: the local-game history has no social controls and keeps the
dictionary entry.
iOS Safari/WKWebView does not shrink the layout viewport for the soft
keyboard (Android Chrome does): the visual viewport shrinks AND offsets
down toward the focused field, and the values do not cleanly revert. The
pinned shell tracked only the height (--vvh), not the offset, so its
top-anchored content misaligned on iOS — empty space below the form,
worst on a repeat focus. Fix (one place; covers NewGame, Chat, Feedback):
- app.svelte.ts syncViewport: also mirror visualViewport.offsetTop into
--vv-top, and scroll the focused field into view on the keyboard-open
transition (iOS does not reliably scroll a pinned document to it).
- app.css: the pinned app-shell body follows top=--vv-top + height=--vvh
(was inset:0), so it stays on the visible area.
- e2e/viewport.spec.ts emulates the visual-viewport resize+offset (a fake
window.visualViewport) to verify the shell follows, on Chromium+WebKit.
Hotseat: returning to the lobby now re-locks the current seat (its PIN is
re-prompted) — LocalSource.relock, cleared in Game.svelte onDestroy.
Root-caused a crash it exposed: a $props() value (id) reads back undefined
during Svelte teardown, so isLocalGameId(id) threw and aborted onDestroy
(breaking navigation) — read the id from the loaded view instead.
- NewGame: all three forms (quick / friends / hotseat) now use the
Profile sub-view's natural-flow .page (no forced height, no pinned-CTA
.grow/.fg scroll), so the screen's single .content scroll + --vvh handle
overflow and a focused name input scrolls into view cleanly — fixes the
keyboard blank-space / deep-scroll regression. One layout rule, one place.
- PinPad: pause 250ms after the 4th digit before the verdict, so the fill
(and the shake on a wrong PIN) reads as a deliberate response.
- e2e: typePin waits for empty dots before typing (robust to the pause).
The nested scroll region regressed the keyboard behaviour (a double
scroll: the whole screen scrolled with a huge blank area under the Start
button, and a focused bottom row hid behind the keyboard). Drop it: the
hotseat form now flows naturally and scrolls with the screen's own scroll
(.page.scrollform: no forced full height, no pinned button), and a name
input scrolls itself into view (centred above the keyboard) on focus.
Owner review of the pass-and-play PR:
- Roster delete (bug): a correct host PIN now ARMS a delete cross next to
the row (mirroring the lobby delete) instead of removing it silently;
tapping the kebab again clears the host authorisation.
- Variant picker (UX): replace the dropdown with the Quick-Match variant
plaques + the multiple-words toggle, one-to-one.
- Keyboard layout (UX): the roster sits in a scroll region with the Start
button pinned (friends-form pattern), so a name input's soft keyboard
shrinks the region instead of leaving a full-height blank spacer painted
behind the keyboard.
- e2e: variant via plaque + a row-delete (arm then cross) regression step.
PWA stale-version (pre-existing, same PR):
- sw.ts: register the network-first NavigationRoute BEFORE precacheAndRoute.
Workbox matches in registration order and the precache route (directoryIndex
index.html) shadowed the shell navigation, serving it cache-first — the old
build's __APP_VERSION__ until a second load. Fixes both the maintenance
self-reload and a cold open after a deploy. Doc updated (ARCHITECTURE).
- source: a finished hotseat game is never locked (its final rack is
shown for review, not an Unlock button); guard locked on !isOver.
- bundle-size: raise the app-entry budget 115 -> 120 KB for the hotseat
UI (PIN pad, roster, host menu), which lives in the always-loaded New
Game / Game / Lobby screens; the offline engine + PIN hashing stay lazy.
Add the Playwright mock e2e for offline pass-and-play (Chromium+WebKit):
create a 2-seat hotseat with a PIN-locked seat, verify the rack is
withheld, unlock (wrong then right PIN), host-skip the current turn, and
terminate from the lobby behind the master PIN.
The e2e surfaced a persistence bug: the roster PINs are $state proxies,
which fail structured-clone on the IndexedDB put (silently — best-effort
store), so a created hotseat game vanished on reload. Snapshot the seats
+ host PIN to plain objects at the create() call site.
Lobby.svelte: hotseat games show the kebab / swipe delete in BOTH the
active and finished groups (not finished-only); deleting one opens a
master-PIN pad first — active = terminate (no result), finished = remove
— so the last mover cannot instantly wipe a game. Local games stay
deletable offline. Non-hotseat games are unchanged (finished-only, free).
Game.svelte drives a hotseat game:
- the seat-to-move's rack is replaced by an Unlock button when the seat
is PIN-locked (board stays visible); canMove gates the move controls
on the unlock; PinPad(verify) -> source.unlockSeat reveals it.
- the hint slot becomes a host button (hints off in hotseat), always
enabled while the game runs (acts on a locked seat too). Master-PIN ->
action sheet: skip current / exclude a player / end the game, each with
a confirm + a fading check; terminate deletes and returns to the lobby.
- per-turn advance re-fetches the next seat's (locked) state; self-resign
and chat are hidden (hotseat resign is a host action, no comms).
- gamesource: expose unlockSeat / verifyHostPin / hostAction on the local
proxy. i18n hotseat.* (en + ru).
NewGame offline 'with friends' now builds a local pass-and-play game:
- lib/roster.ts: keep-last-valid name + roster->seats (unit-tested).
- NewGame.svelte: master host-PIN gate (rows disabled until set),
'are you playing too?' prompt seating the host at row 0, 2-4 player
rows with inline name validation + optional per-seat PIN, add/remove
(remove behind the master PIN), variant + multiple-words, Start.
- PinPad: verification via a verify(pin) callback (UI-held lock at
creation, source-held in-game) instead of a lock prop.
- i18n: hotseat.* (en + ru); the offline mode selector is now shown offline.
Extend the local game to offline pass-and-play (hotseat):
- serialize.ts: Seat.pin, record hotseat + hostPin (all optional; old
vs_ai records read hotseat as false).
- source.ts: create() takes hotseat/hostPin + per-seat pins; stateView
reveals the seat-to-move's rack and withholds it (locked) when that
seat is PIN-locked, until unlockSeat; ephemeral per-turn unlock
re-locks on advance; new unlockSeat / verifyHostPin / hostAction
(skip/resign/terminate); gameView sets vsAi=!hotseat + the hotseat flag.
- model.ts: GameView.hotseat, StateView.locked (offline-only, optional).
Tests: source.hotseat (lock/unlock/re-lock, host skip/resign/terminate,
master-PIN gate, natural-end persistence) + serialize hotseat shape.
Groundwork for offline pass-and-play (hotseat) seat/host PIN locks:
- lib/pin.ts: salted SHA-256 PinLock (newSalt/hashPin/newLock/verifyPin);
a social lock for a shared device (documented, not cryptography).
- components/PinPad.svelte: 4-digit keypad (set/verify/change), auto-submit
on the 4th digit, shake on mismatch, hardware-keyboard support.
- i18n: pin.* keys (en + ru).
Engine/source/UI wiring follows.
navigate() wrote location.hash and left router.route to the asynchronous
hashchange event. bootstrap flips app.ready in the same tick right after
navigate('/login') on an unauthenticated cold start, so for one frame the app
rendered with app.ready=true and the stale route ('lobby', from the empty hash)
— briefly mounting the lobby shell (tab bar + a doomed games.list) under the new
login screen before hashchange settled it.
Update router.route synchronously inside navigate(); the later hashchange
re-parses to the same value. This removes the boot lobby-flash (and its spurious
games.list 401) and, as the root cause, the offline e2e flake: enterLobby could
latch that transient lobby tab-bar instead of clicking through login, then the
Settings-tab click at line 44 fought the tab detaching into the login slide
(~7% of runs, both engines).
Also:
- offline.spec enterLobby: wait for the guest button and click it, instead of a
point-in-time count() that a pre-login splash frame sampled as 0 (skipping the
click and hanging / latching the transient).
- New e2e router.spec pins the synchronous-route property (RED on the old code,
which returned the previous route; GREEN now) via a mock-only __router seam.
Verify: check 0 / unit 490 / build / bundle 114.3/115 / full e2e 200 / the
offline+router stress at 40x on both engines 160/160 (was 6/80 failing).
Entering a vs_ai game from the lobby armed the idle-hint countdown only in load() (after
the gameState round-trip), so the lock popped in after a visible delay. Arm it on the
instant warm-cache render in onMount too — the preloadGames-warmed StateView carries
hint_unlock_left_seconds; load() then refreshes the snapshot. A first move (0 seconds
left) stays open.
Online vs_ai hints were broken: #207 made the vs_ai hint button always-enabled and
wallet-free (assuming all vs_ai = the offline idle-gate), but the backend still served
online vs_ai from the allowance/wallet, so over-clicking hit ErrNoHintsLeft -> a generic
error toast. Now online vs_ai uses the SAME idle-gate model as offline.
Backend: Hint() for a vs_ai game skips the allowance/wallet and increments no hints_used
(owner: vs_ai counts toward no hint statistic), and is idle-gated from the SERVER clock --
it returns ErrHintLocked (code hint_locked) until the robot's last move + 30 min, else
serves the top move. GameState/StateView expose hint_unlock_left_seconds (server-computed
seconds remaining; 0 for a human game / first move / not-your-turn). Pure helper
hintUnlockLeftSeconds unit-tested.
Wire: StateView gains hint_unlock_left_seconds (FlatBuffers, additive); pkg/wire + gateway
transcode carry it (round-trip test).
Client: the gate counts down from a MONOTONIC clock (performance.now()) anchored to the
source's seconds-left when it lands (on load from the view; to the full window when the
robot moves), so a client clock change cannot skew it and a relaunch re-reads a fresh
value. The vs_ai hint button (online + offline) shows the lock + toast; doHint handles the
hint_locked backstop by re-syncing. Replaces #207's absolute hintUnlockAtMs on the
wire/model/delta (the offline record keeps the absolute for persistence; the view exposes
seconds-left).
Docs FUNCTIONAL(+_ru)/ARCHITECTURE updated. Verified: go build/vet + game/server/transcode
tests (+ new hintUnlockLeftSeconds); ui check 0 / unit 490 / e2e 198 (one pre-existing
webkit offline flake) / app entry 114.2/115.
Two pre-existing offline bugs, both exposed once offline mode became usable (cold boot +
toggling), owner-reported on the contour.
Bug 1 -- offline tiles render weight 0. The rack/board read tile values from the
lib/alphabet cache, populated only by the online wire codec (server-sent alphabet) or the
mock (so the e2e masked it). A local game never goes through the codec, so on a cold
offline boot with no prior online session the cache was empty and every value read 0
(scores stayed correct -- they come from the offline ruleset). Fix: the local source
seeds lib/alphabet from the static offline ruleset (letters + values) when it builds a
game view.
Bug 2 -- the lobby showed (and could open) the other mode's game after a toggle. Two
causes: (a) the lobby cache was not mode-tagged, so getLobby() instant-rendered the last
snapshot regardless of mode; (b) load() wrote the module list after an await with no
generation guard, so a slow online gamesList() finishing after a fast offline list() (or
vice versa) left the wrong mode's games on screen. Fix: tag the snapshot with offline and
gate getLobby() on it; add a load-sequence guard so only the latest load() writes.
- localgame/source.ts: ensureAlphabet from the ruleset in gameView (+ unit test).
- lobbycache.ts: LobbySnapshot.offline + getLobby(offline) mode check (+ tests).
- Lobby.svelte: setLobby tags the mode; load() carries a generation guard.
check 0 / unit 485 / e2e 198 / app entry 113.8/114.
Per the owner's call, the idle-hint gate now PERSISTS across leaving and reopening the
app, instead of the session-scoped monotonic clock: the unlock is a wall-clock instant
(hintUnlockAtMs) stamped from the robot's reply, stored on the local record, carried on
the game view + the opponent_moved move delta, and read through a sanitiser that caps it
at now + the window. So:
- the wait survives a relaunch (a stuck turn is not forgotten);
- a device clock set BACK cannot freeze the gate (the cap bounds the remaining to the
window and self-heals on the next read);
- a clock set FORWARD just opens the hint early -- accepted as harmless for a solo game.
- lib/hints.ts hintGateRemainingMs now takes the unlock instant + clamps to the window.
- localgame: re-add hintUnlockAtMs to the record/meta; stamp it off the robot's reply;
sanitise on read (a shared hintUnlock helper feeds stateView + the opponent_moved event).
- gamedelta + PushEvent: the move delta carries hintUnlockAtMs so the view stays fresh.
- Game.svelte: hintUnlockAt derives from the view; the tick + lock + toast unchanged.
- offline.spec.ts: also assert the lock survives a reload (the wait persisted).
- Docs FUNCTIONAL(+_ru)/ARCHITECTURE updated (persist + sanitiser, not monotonic-resets).
A vs_ai hint is now unlimited and wallet-free, but idle-gated as an anti-frustration
aid: it unlocks only after the player has been stuck ~30 min on a turn (timed from the
robot's last move; the human's first move, before the robot has played, is exempt).
While gated the hint button carries a small lock badge and a tap shows the remaining
minutes ('Available in N min.'); the lock lifts live at the mark.
The gate is enforced CLIENT-SIDE against a MONOTONIC clock (performance.now()), never a
wall-clock timestamp: a device clock the player controls (or an auto-sync) must not be
able to open or freeze it. The wait is therefore session-scoped -- a reload restarts it
(there is no tamper-proof way to carry idle time across a relaunch without a wall clock).
An online vs_ai game will gate the same way but from the server's clock (a follow-up).
- lib/hints.ts: HINT_GATE_MS + pure hintGateRemainingMs (monotonic) + hintLockMinutes;
removed the wall-clock hintRemainingMs. Unit-tested red->green.
- Game.svelte: the monotonic gate (hintGateStart/monoNow, armed on the turn change), a
vs_ai hint button (plain: no confirm, no count; lock badge + gated tap -> toast), a
live 10s tick.
- localgame: removed the wall-clock hint gate and the now-dead robotLastMoveAtUnix field
from source.ts/serialize.ts (the client is authoritative); hint() just serves the top
move.
- i18n game.hintLockedIn.
- offline.spec.ts: assert the first move is un-gated and the lock arms after the robot moves.
- Docs FUNCTIONAL(+_ru) + ARCHITECTURE; bundle budget 114->115 (game-screen feature).
A Playwright spec drives the whole offline flow in the mock build: force the
installed-PWA display mode, enter offline via the Settings toggle (its readiness check
fetches the dawgs), assert the blue chrome + online-games-hidden + Stats-disabled, then
create and play a device-local English vs_ai game with a pinned bag seed (deterministic
rack NEWYMAO) -- play the opening WAY across the centre, watch the robot reply with a
real move, and reload to confirm the IndexedDB replay.
Enabling infra (all e2e-only; nothing enters the production build):
- mock/client.ts fetchDict serves the per-variant dawgs from the preview build's
/e2edict/ (was: threw 'unsupported in mock').
- scripts/e2e-dict.mjs copies the real dawgs into dist-e2e from E2E_DICT_DIR (the ui CI
job fetches the scrabble-dictionary release like the Go jobs; local default: the
sibling scrabble-solver/dawg); playwright.config runs it between build and preview.
- localgame/id.ts setForcedSeed + gateway.ts window.__mock.setLocalSeed: a mock-only
seam to pin a local game's bag seed (tree-shaken from prod).
- ci.yaml ui job: fetch the dawgs + pass E2E_DICT_DIR to the e2e step.
- docs/TESTING.md: the offline e2e + the mock-dawg wiring.
Verified: check 0 / unit 482 / e2e 198 (both engines) / app entry 113.8/114.
