  "description": "Declarative model x transport profile. Native key is selected by the exact package, never supplied as a public board-id override. Candidate profiles grant no readiness or authority; exact metadata and observed activity are independent qualification gates. No AUX modes, arbitrary config commands or streamers in this slice. P096-004 built-ins also supply a readable version/form and per-stream continuity policy. Optional lab observations are scoped activity evidence, never active-channel guarantees, heart-rate inference or qualification; units unknown until P096-007b.",
