# Dockerfile.unified — Single multi-target Dockerfile for all OpenAB agent variants.
# Usage: docker build --target <agent> -t ghcr.io/openabdev/openab:<tag>-<agent> .
#
# The shared builder compiles the openab binary once (unified mode, superset).
# Each agent target is a thin runtime layer that installs only the agent CLI.
# Architecture:
# local_builder — compiles the openab binary (only runs locally or in build-core CI job)
# builder — alias that resolves to local_builder (default) or a prebuilt registry
# image (when BUILDER_IMAGE is overridden in CI). BuildKit prunes
# local_builder when it's not needed.
# <agent> — thin runtime layer that installs only the agent CLI + copies binary
# from builder stage.

# Global ARG — must be declared before first FROM for use in FROM instructions
ARG BUILDER_IMAGE=local_builder

# =============================================================================
# Stage: builder — compile openab binary (unified mode)
# Stage: local_builder — compile openab binary (unified mode)
# Only executed during build-core or local dev. When BUILDER_IMAGE is overridden
# (CI build-agents), BuildKit prunes this stage entirely via dependency analysis.
