Answer the auditor's hardest question in one query — 'prove it.'

'Prove it' ends more audit meetings than any other phrase — and most companies answer with a project: weeks of collection, interviews, and reconstructed timelines. Audit Evidence makes the answer a query instead. Every mutation seals actor, policy decision, and source digests at commit time, so the trail exists before anyone asks for it.

## Evidence lifecycle

Each stage below seals accountability at commit time — nothing reconstructs after the fact from memory or scattered logs.

section: stages

### Seal

Mutations bind actor, policy decision, source digests, and state transition into envelopes at commit. The seal is the proof, created when facts are fresh.

### Trace

Lineage links envelopes into causal chains across domains. Any outcome traces back through every decision and event that produced it.

### Disclose

Audits, investigations, and records requests run as structured queries with redaction applied. Responses carry their own provenance for challenge.

## Evidence guarantees

- **Actor binding:** ARGUS identity and policy-decision reference on every mutation
- **Source linkage:** Input digests and source events cited inside the sealed envelope
- **Causal lineage:** Timeline-X references enabling replay and downstream impact tracing
- **section:** capabilities

## Evidence by industry

Audit proof bends per industry — same sealed envelopes, different examiner expectations.

### data View

section: industries

### Manufacturing

Device history with work-order lineage, inspection results, and operator identity per unit. Customer and regulator audits assemble from sealed events.

### Government

Appropriation-to-outcome chains with authorization evidence per step. Sunshine and FOIA responses generate as redacted queries instead of document hunts.

### Financial Services

Transaction lineage with policy versions and approval chains intact. Examiner requests resolve to envelope queries with lineage they can follow.

## Audit Evidence questions

### Section 1

What does an evidence envelope contain?

Actor identity, policy decision reference, source event identifiers, input digests, and the resulting state transition — sealed at commit time.

### Section 2

How do public-records requests work?

As structured queries over sealed envelopes with redaction policy applied, instead of weeks of manual collection and review.

### Section 3

Our auditors bill by the hour. Won't this transparency cost us more?

The opposite: auditors bill discovery hours hunting documents. Pre-assembled evidence collapses fieldwork to confirmations — ask any client who has lived both.

value: When an auditor asks who approved what and on which evidence, the answer is one query away. FOIA requests, sunshine-law reporting, and public-records obligations resolve through structured evidence retrieval — not manual document collection across departments.
