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.
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.
