One distroless image of about 25 MB carries the binary, the built frontend and
the derived dictionary. The 179 MB upstream release is downloaded in a builder
stage and never reaches the final image; the derived wordlist is copied in as
its own layer alongside its licence, attribution and notice, because CC BY-SA
4.0 applies wherever that data is distributed and an image is distribution.
FIXTURE_DICT=1 builds the same Dockerfile against the checked-in word sample,
so the image is built and smoke-tested on every push rather than only at
release. An image built only at release time is an image that breaks at release
time.
CI runs the Go suite under race detection, the frontend type check and tests,
the browser suite, and the image with its licence assertions. The wire contract
keeps its own workflow; the test steps it duplicated were removed from it.
docs/deployment.md covers configuration, the reverse-proxy settings that each
break the game in a way that looks like something else, and what a restart
costs.
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.
