Add a per-game rule chosen on New Game for Russian variants (default off = the
single-word rule; on = standard Scrabble). Off, only the main word along the play
direction is validated and scored; perpendicular cross-words are ignored,
including in robot move generation. The rule rides every create and enqueue
request and joins the matchmaking key, so games and auto-match stay one uniform
path; "Russian-only" is a UI affordance (English always sends standard and shows
no toggle).
- Engine: consume scrabble-solver v1.1.0's PlayOptions{IgnoreCrossWords}, threaded
through engine.Options.MultipleWordsPerTurn -> playOpts() into validate, score
and generate.
- Backend: thread the flag through game CreateParams/Game + store (games column),
lobby InvitationSettings + invitation row, and the matchmaker queue key (variant
+ rule); persisted, so a rebuilt-from-journal game keeps it. Baseline migration
gains multiple_words_per_turn (DB not versioned); jet regenerated.
- Edge: multiple_words_per_turn added to the EnqueueRequest / CreateInvitationRequest
FlatBuffers tables (Go + TS regenerated) and threaded through the gateway.
- UI: a "Multiple words per turn" toggle on New Game, shown for Russian variants
only (auto-match and friend invite), default off; English silently sends standard.
- Tests: backend engine/matchmaker; UI unit (gating) + Playwright e2e (solver
corner-case + GCG fixtures ship in v1.1.0). Docs + PRERELEASE tracker updated.
A single tile that only extended a word perpendicular to the client-declared
direction was rejected: the UI always sent dir=H for one-tile plays (the
dirOverride/Controls toggle was orphaned in the Stage 7 game rework), so placing
"А" above "БАК" to form "АБАК" failed the solver's main-word-length check even
though the word is in the dictionary.
Make the backend infer a play's orientation from the placed tiles and the board
(internal/engine.resolveDirection): two or more tiles by the line they share, a
lone tile by the axis it abuts (longer word wins, horizontal on a tie). Direction
becomes an output, not an input: drop dir from the SubmitPlay/Eval wire requests
and add it to EvalResult. Journal replay keeps trusting the stored "H"/"V"
(SubmitPlayDir) so a rebuilt game matches the one committed.
UI: stop computing/sending direction; the preview now shows the words a move
forms with its total score (game.previewWords); the make-move control is disabled
until the play is confirmed legal; the "your turn" label hides while tiles are
pending. Delete the orphaned Controls.svelte.
Regenerate the FlatBuffers bindings (Go + TS) and update the gateway transcode
and the loadtest edge client to the new contract. Bake the decision into
ARCHITECTURE.md (§5/§9.1), FUNCTIONAL.md (+ _ru) and the backend README.
Move the cross-file integration fixtures — the service constructors
(newGameService/newSocialService/newRobotService/newMatchmaker), the game-assembly
helpers (newMirror/newGameWithSeats/newDraftGame), account provisioning
(provisionAccount/provisionGuest) and the stats reader — out of the domain test
files (newGameService alone was used by 10 files) into a single
backend/internal/inttest/helpers.go. Helpers used by a single file stay local.
Pure relocation: the helper bodies are unchanged, no test logic changes; the
imports the moves left unused are pruned. go vet -tags=integration is clean.
Squash the 12 goose migrations into one 00001_baseline.sql (there is no prod
data; verified schema-identical to the chain via a pg_dump diff + the green
integration suite) and rename the game-variant labels
english/russian_scrabble/erudit -> scrabble_en/scrabble_ru/erudit_ru across the
backend, the FlatBuffers wire values and the UI.
dawg filenames and the Go enum identifiers are unchanged; the i18n display keys
are kept. Adds PRERELEASE.md (the R1-R7 pre-release tracker), linked from
CLAUDE.md. Contour DB wipe and the scrabble-dictionary tidy are follow-ups.
Two owner-reported defects from a live contour game.
A. Frequency: the robot's proactive nudge fired hourly for 12h+ (a 12h idle threshold
then the 1h cooldown, uncapped). Replaced with a lengthening, randomized schedule
(proactiveNudgeGap): the first nudge ~60-90 min into the human's turn, each later gap
growing toward 1-6h (uniform sample in [60min, ceil], ceil ramping 90min->6h over 12h
of idle, measured from the previous nudge), so a long wait gets a handful of
increasingly-spaced reminders instead of a stream.
B. Language: out-of-app push routed by the recipient's GLOBAL service_language
(last-login-wins), so after re-logging via the RU bot an English game's nudges came
from the RU bot. Now a game push (your_turn, game_over, nudge, match_found) carries
the game's own language (engine.Variant.Language) on push.Event, and the gateway
routes by it (falling back to service_language for non-game pushes). The New-Game
variant-gating guarantees the game's bot is one the player has started, so delivery is
never blocked.
Tests: proactiveNudgeGap unit + retimed TestRobotProactiveNudge; TestVariantLanguage;
emit your_turn/game_over language; TestNudgeRoutedByGameLanguage integration. Docs:
ARCHITECTURE (§7 nudge, §10/§13 routing), FUNCTIONAL (+ _ru), PLAN tracker.
TestRobotPoolProvisionsRobotAccounts asserted robots block friend requests; they no
longer do (a request stays pending and expires like a human ignore). Assert chat is
blocked and friend requests are open. (Unblocks the integration job / contour deploy.)
