  "description": "Reproducible twin of create_tempo_sync (core, without the optional beat-event emitter DAT): a Beat CHOP runs a tempo clock and a Null CHOP exposes its ramp/pulse/count/beat/bar/bpm channels as a stable bind point for the whole project. Set the project tempo via the timeline/Beat CHOP; bind any parameter to op('tempo')['ramp'] (0..1 bar phase), ['pulse'] (per-beat trigger) or ['bpm']. The live event-broadcast emitter the tool can add is omitted here because it depends on the MCP webserver runtime (not reproducible in a static recipe). Offline-validated against RecipeSchema; UNVERIFIED pending live cook-check.",
