Adding the loadtest module to go.work (use ./loadtest + the scrabble/gateway replace it needs) broke the other services' Docker builds: their reduced workspace still referenced ./loadtest (not in their build context), failing with 'cannot load module loadtest: open loadtest/go.mod: no such file or directory'. Each service Dockerfile now also -dropuse=./loadtest; backend and telegram (which do not COPY ./gateway) additionally -dropreplace the loadtest-only scrabble/gateway replace. Verified by building all three images plus loadtest locally.

# Multi-stage build for the backend service. Mirrors platform/telegram/Dockerfile:
|
|
# a golang-alpine builder yields a static binary shipped on distroless nonroot.
|
|
#
|
|
# The dictionary DAWGs are baked in from the scrabble-dictionary release artifact
|
|
# (Stage 14) — the same set the Go CI downloads — and BACKEND_DICT_DIR points the
|
|
# binary at them. The published solver module is fetched directly from Gitea
|
|
# (GOPRIVATE), so the build stage needs git and network.
|
|
#
|
|
# Build from the repository root so go.work, go.work.sum, pkg/ and backend/ are all
|
|
# in the Docker context:
|
|
# docker build -f backend/Dockerfile -t scrabble-backend .
