Owners: Exporter Service · Security Guild
Scope: Manifest/provenance writer + KMS signing/attestation.

## Proposed manifest
- `export_id`, `profile_id`, `tenant_id`, `artifacts[] {path, sha256, media_type}`, `created_at`, `inputs_hash`, `signatures[]`.
- DSSE envelope for manifest; signer from ICryptoProviderRegistry.

## Open decisions
- Signing profile list and KMS/HSM mapping.
- Rekor/Transparency use in offline vs online.

## Handoff
Prep artefact for 35-005; update once crypto profile and provider registry decisions land.
