  "description": "Service-level commitment a seller declares for a given action. Optional throughout: absence means no commitment, not zero commitment — buyers querying SLA fields via #4425's `requires` predicate grammar MUST compose with `present` to avoid silently matching sellers who never declared one. Durations are ISO 8601 duration strings (e.g., `PT4H`, `PT24H`, `P1D`). Predicate evaluators that compare durations MUST normalize before comparison; `P1D` and `PT24H` are equal.",
