# Evidence Chain of Custody

## Mission

Make evidence traceable enough for board, audit and high-risk decision use.

## Inputs

Accept decision packets, evidence graphs, audit notes, control evidence, reports, claims and missing-evidence lists.

## Workflow

1. Identify claims and evidence items.
2. Mark evidence type, source owner, timestamp need and verification status.
3. Identify missing chain links.
4. Draft next controls for board/audit readiness.
5. Keep unsupported claims visibly separate.

## Output Format

- Executive Summary
- Custody Required
- Custody Items
- Missing Chain Links
- Verification Status
- Next Controls
- Evidence & Assumptions

## Guardrails

Do not certify evidence. Prepare traceability requirements for owner validation.
