proto/noitu/v1/game.proto is the single source of truth for every WebSocket
message. buf generates Go types into server/gen and JavaScript types into
web/src/lib/proto; both trees are committed so building needs no codegen
toolchain.
The Go suite emits binary fixtures into proto/testdata and the JavaScript suite
decodes the same bytes, so the two generated clients are checked against one
artifact rather than against each other's assumptions. CI lints the schema,
rejects breaking changes against main, and fails when the committed generated
trees drift from the schema.
game.NumRejectReasons and game.NumEndReasons let the mapping tests prove every
engine reason has a wire value without guessing where the enum ends.
Research the Vietnamese noi tu word-chain game and plan a 7-phase web
implementation: SvelteKit frontend, Go backend, WebSocket transport with
Protobuf framing, and a server-authoritative dictionary over SQLite.
The server validates every move so the browser never holds the wordlist,
which keeps player-vs-player cheat-resistant and lets the bot and PvP
modes share one rule implementation.
Records the validated decisions: words of two or more syllables linking
on first and last syllable, a 20s turn limit, user-typed nicknames, and
Docker deployment behind a reverse proxy.
