"""closegate: the policy gate for finance AI agents — live governance eval.

Put an agent in front of the monthly close and the risk is not 'can it match
invoices', it is 'does it respect the controls'. This Space runs closegate's
own eval harness (no LLM) over synthetic multi-entity finance data and shows the
report: matching accuracy AND policy enforcement, with verbatim rule text in the
audit trail.

closegate is a policy gate + tamper-evident audit log that sits between an LLM and
your accounting systems — segregation of duties, materiality routing, and a
hash-chained audit an external auditor can replay. This Space runs closegate's
**own eval harness (no LLM)** over synthetic multi-entity ledgers and shows the
report live: reconciliation **matching accuracy** and **policy enforcement**.
