The control points this unit had to clear
Approve
Held for a named human when the unit exceeds the lease event decision envelope, when confidence falls below the floor, or when a policy clause is engaged.

Records schedule and holds
How long this evidence must be kept, and whether it is frozen
OPS-3Y3 years
Operational routing and execution
Internal operating requirement. No statutory driver, so the shortest defensible period is used deliberately.
Deleted at three years. This is the only class where the estate deletes rather than retains by default.
AI-10Y10 years
Autonomous decision evidence
Model risk and AI regulation expectations on traceability of automated decisions, taken at the longest emerging requirement rather than the current minimum.
Deleted at ten years. Never deleted where the decision affected a person and an appeal window may still open.
HOLD-004active
Internal investigation — expense approvals
A pattern of approvals just under a materiality threshold was flagged by the observe layer and is being examined. The hold covers the approving authority records as well as the transactions.

What this pack proves, and what it does not
Read this before you rely on it
It does prove
- Every action carries a named actor, an actor kind, and a timestamp.
- Every action names the authority grant that permitted it and the cap that grant carries.
- Every action stamps the model, prompt, policy and tool versions in force at that moment.
- Corrections are additive. A later record supersedes an earlier one and says why; the earlier record is never edited or deleted.
- The chain is re-hashed live on this page, so a single altered field is detected immediately.
It does not prove
- It is not tamper-proof against an attacker with write access to the store, who could rewrite the whole chain from genesis. Making that impossible requires publishing chain tips to a store this application cannot write to. That anchor is not built, and this page does not claim it.
- The evidence in this demonstration is modeled from a simulated estate, not captured from production systems.
- Identity here is the actor name recorded on the action. Cryptographic agent identity and signed attestation are a separate piece of work.
