- Which platform capabilities engaged.
- Every guardrail decision.
- The actions blocked vs executed.
- The fallbacks fired.

- A SHA-256 integrity hash, hash-chained over the event timeline — anyone can recompute it from the timeline.
The hash is computed over the run’s event timeline, so altering any recorded step changes the digest. A reviewer recomputes
integrity_sha256 from the timeline and compares — that’s what makes the receipt tamper-evident.
