Store the hints a player used in each game, and add two lifetime tiles — Moves and Hint share — to the statistics screen. - per-game: game_players.hints_used now counts EVERY hint (allowance + wallet), not just the free allowance, so it is the seat's true total hints used this game. The allowance decision (used < HintsPerPlayer) and the hint badge values (hints_remaining / wallet_balance) are unchanged — the lobby hint-count fix does NOT regress; only the admin "hints used" column, which silently under-counted wallet hints, becomes accurate. - account_stats gains two summed counters: moves (the player's plays — passes and exchanges excluded) and hints_used (every hint). Computed at game finish in buildStats over the same non-guest, non-honest-AI games as the rest of the stats. - wire: StatsView gains moves + hints_used (trailing); gateway + UI codec + model; regen. - ui: two tiles (Moves, Hint share = hints_used/moves, one-decimal % in the active locale); card order games·wins·draws·losses·moves·hint-share·best game·win-rate. - docs: ARCHITECTURE §9 + baseline comment, FUNCTIONAL (+ru), UI_DESIGN. Tests: TestHintPolicy (hints_used counts the wallet hint), TestGameLifecycleAndStats (moves>0, hints=0), gateway stats round-trip, UI hintShare unit + codec + e2e.
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 (includingValidateLoginWidgetfor 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.
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.
