Because every decision the gate makes writes one immutable, hash-chained line, the board pack is not assembled after the fact, it already exists. Below is a representative example: a monthly AI governance and sovereignty audit, generated autonomously for an NHS trust. No figure in it was entered by hand.
A six-month documentation project becomes a download.
Example pack for illustration. Figures are a faithful reconstruction of a governed estate's telemetry; cost-avoided is a modelled counterfactual, not measured spend.
Heimdall sits between the trust's clinical applications and every model that serves them. It records each request, evaluates it against ratified policy, routes it to the correct jurisdiction, and seals an entry to the ledger. The audit is a faithful reconstruction of that record, produced without human intervention.

“Nothing happened
off the books.”
Every change to the estate's behaviour is a governed event with an author, a timestamp and a ledger anchor. The pack is sealed against tamper, attested by the autonomous governance engine, and handed to the board as evidence, not as a translation of evidence.
