# Telegram platform images: the home validator (HMAC of Mini App / Login Widget
# data, no Bot API, no VPN) and the remote bot (Bot API long-poll + sendMessage,
# dialing the gateway over the reverse mTLS bot-link). One build stage compiles both
# binaries; the `validator` and `bot` targets each ship one on distroless nonroot.
#
# The platform imports only the shared scrabble/pkg module, so the build drops the
# other workspace modules (backend, gateway, loadtest), the loadtest-only
# scrabble/gateway replace and the scrabble-solver replace from a copy of go.work: it
# needs neither their sources nor the solver sibling checkout.
# Build from the repository ROOT so go.work, pkg/ and platform/telegram/ are all in
# the context (see deploy/docker-compose.yml, which sets context: ..).
