# =============================================================================
# swift — On-Device CoreML Bioacoustic Classifier
# =============================================================================
# CoreML only exists on Apple platforms. This container therefore runs the
# *fallback* ONNX path (currently routed through the deterministic stub
# classifier shipped in `Sources/Runtime/Tools/CoreMLClassify.swift`).
#
# On macOS you should instead use `make run-host-runtime`, which runs the
# Swift runtime natively on the host and uses real CoreML when an
# `.mlpackage` is provisioned. This Dockerfile remains useful for:
#   * proving the SDK resolves at build time (`make verify`)
#   * running the client TUI in the standard 3-container layout
#   * containerised CI runs on Linux
