What should a verifiable AI-service receipt prove?

Autonomous software can discover and use APIs, models and data in seconds, but service accountability is still usually trapped inside private dashboards.

We think a useful receipt should preserve four things: the measurable terms, the evidence supplied, the exact rule version and a stable commitment that another system can independently recheck. It should also state its limits: a receipt can prove what was evaluated without pretending every external input was true.

What would make this useful in your stack—authenticated monitoring sources, signed provider evidence, more SLA rules or examples for a particular agent framework?
