pkg/version.Version (default "dev") is set at link time via -ldflags from each service Dockerfile's VERSION build-arg, which the deploy passes as the git tag (git describe --tags). It surfaces as the OpenTelemetry service.version resource attribute (so Grafana/Tempo are version-aware), alongside the SPA's existing About version. Adds the VERSION build-arg to the backend/gateway/validator/bot compose builds and a serviceResource test covering service.name + service.version.
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.
