KnightGrid for Internal Audit

Don’t reconstruct the decision. Replay it.

Every approval carries its inputs, rule versions, evidence, reviewer actions and exceptions, frozen together when it is signed.

The audit review

From approval to proof, step by step.

The audit trail is not assembled later. It is part of the decision itself.

01 / Select

Open any decision as it existed then.

Identity, tier, outcome, owner, and timestamp locate one exact record—not today’s version of the vendor.

Decision IDOwnerTimestamp
02 / Inspect

See the basis, not just the verdict.

Each scoped control points to accepted evidence, rejected evidence, and the rule version that produced its state.

22 scoped controlsEvidence refsRule versions
03 / Follow

Find every place judgment entered.

Reviewer actions, contradictions, conditions and overrides are named, dated and kept beside the computed result.

Named reviewersOverride ownerExpiry
04 / Verify

Replay the signal from source.

Recompute the signal from the frozen snapshot, compare it with the recorded one, then verify the sealed record has not changed.

05 / Export

Take the record into your working papers.

Work in your own read-only view, or export the Decision Report as a PDF: the record as it stood at signature, with its snapshot hash, so the file can be matched to the sealed original.

Computed result and human judgment remain distinct.

The record shows who changed what, why, and for how long.
