AI-Tool-Usage Workpaper Record
Composes a documentation-element workpaper record from an existing OCG receipt — referenced by tool identity, execution hash, and kernel digest, never re-embedded — plus a declared determinism class and conventions, engagement metadata, and a reviewer sign-off statement.

⚠ This kernel produces an EVIDENCE FORMAT, not an audit opinion. It makes no PCAOB or AICPA endorsement or compliance-sufficiency claim — it is designed to satisfy the documentation elements (tool identity, inputs/outputs, limitations, sign-off) described in a cited standard reference. Reviewer sign-off here is a declared role and statement, not a cryptographic signature; an OPTIONAL §16 eddsa-jcs-2022 signature on the exported artifact turns it into a countersigned record.
Carries no client or personnel identity beyond a declared reviewer role and a caller-controlled engagement identifier. Real reviewer identity stays off-platform.
This evidence pattern is designed to pair with local recompute infrastructure such as Helm, which runs deterministic workflow packs on the firm's own machine. See Helm.
