# Crucible toolchain image: registry.westgate.pw/sow/crucible:<git-sha>
#
# Reproducible multi-stage build, no on-VPS build. Produces every cmd/* binary
# and ships them on a static base. The `crucible` dispatcher is the entrypoint;
# consumer CI can also call the standalone crucible-<name> binaries by path.
#
# NOTE (Phase 5 scaffold): the binaries are pure stdlib and fail closed until
# the operator migrates the internal pipeline. When the music pipeline is wired
# it needs ffmpeg at runtime — switch the final stage to a debian-slim base with
# ffmpeg then (see docs/migration-from-nwn-tool.md).
