Live play now exchanges per-variant alphabet indices instead of concrete letters (rack out; submit-play, evaluate, exchange, word-check in). The client caches each variant's (index, letter, value) table behind StateRequest.include_alphabet and renders the rack and blank chooser from it, dropping the hardcoded value/alphabet tables. History, the durable journal and GCG stay decoded concrete characters (ARCHITECTURE §9.1, unchanged). - pkg/fbs: new AlphabetEntry + PlayTile; StateView.rack -> [ubyte] + alphabet; StateRequest.include_alphabet; SubmitPlay/Eval tiles -> [PlayTile]; Exchange tiles + CheckWord word -> [ubyte] (committed Go + TS regenerated). - engine: AlphabetTable + a cached per-variant codec (LetterForIndex/EncodeRack/ DecodeTiles/DecodeWord) + BlankIndex sentinel; Go parity test. - backend server edge maps index<->letter (new thin game.Service.GameVariant); game.Service domain methods, engine.Game and the robot keep one letter-based play path. The gateway forwards indices verbatim (no alphabet table). - ui: lib/alphabet.ts in-memory cache; codec encodes/decodes indices; premiums.ts is geometry-only; the mock seeds a fixture table; the UI normalises display to upper case (codec + cache), leaving placement/board/checkword unchanged. Parity moved to the Go engine.AlphabetTable test; premiums.ts loses its value tables. Discharges TODO-4.
pkg
Shared wire contracts for the Scrabble platform (module scrabble/pkg),
imported by both backend and gateway. It carries no logic — only the
generated message types and the schemas they come from.
Layout
proto/push/v1/ # backend -> gateway live-event gRPC channel (Push.Subscribe)
# committed generated Go (*.pb.go, *_grpc.pb.go)
fbs/scrabble.fbs # FlatBuffers edge payloads (one `scrabblefb` namespace)
fbs/scrabblefb/ # committed generated Go for the schema
proto/push/v1is the single gRPC server-stream the backend exposes and the gateway subscribes to (Event{user_id, kind, payload, event_id}); thepayloadis an opaque FlatBuffers body the gateway forwards verbatim.proto/telegram/v1is the Telegram connector's RPC contract (Stage 9; Stage 11 addedValidateLoginWidgetfor the web Login Widget sign-in).fbsholds the client↔gateway request/response and event payloads as FlatBuffers tables. The backend encodes the push payloads from these types; the gateway transcodes the rest to and from the backend's JSON; the UI generates TypeScript from the same.fbs(Stage 7).
Generated code
Committed (CI only builds it); regenerate dev-time after editing the schemas:
make -C pkg tools # go install protoc-gen-go + protoc-gen-go-grpc
make -C pkg gen # buf generate (proto) + flatc (fbs)
flatc is pinned to 23.5.26 to match the github.com/google/flatbuffers
Go runtime in go.mod; generating with another version is refused.
Workspace wiring
scrabble/pkg is a bare-path module (no dot), so — like scrabble-solver — it
cannot be fetched as a versioned dependency. go.work carries use ./pkg and
replace scrabble/pkg v0.0.0 => ./pkg; consumers require scrabble/pkg v0.0.0.
