# Runs the platform-agnostic ContinuityCore test suite on Linux for every PR.
#
# BeatTracker/KeyDetector import Accelerate (Apple-only), and SwiftPM compiles the target as a
# unit — so the full package can't build on Linux. Per AGENTS.md, we assemble a throwaway
# package from the non-Accelerate sources/tests (111 of ~127 test cases: Camelot/flow ordering,
# crossfade curves, transition plan, loudness, silence trimming, YouTube/Spotify URL + page
# parsing). The BPM and key suites still need a Mac.
