# Policy Attestation Prep — PREP-POLICY-ATTEST-73-002

Status: **Ready for implementation** (2025-11-20)
Owners: Policy Guild
Scope: Define editor DTOs/validation schema for linking VerificationPolicy (73-001) into policy-engine UI/SDK.

## Requirements
- Editor DTO `VerificationPolicyUpdate` with fields mirroring 73-001 schema; arrays sorted.
- Validation rules: same as 73-001, plus max subjects = 500, max requiredAttestors = 20.
- Error codes: `ValidationFailed`, `DuplicateKey`, `NotFound`.

## Acceptance criteria
- DTOs + validation rules documented; examples with fixed timestamps and hashes.
- SDK notes: generated models should expose immutable collections and validation annotations.
