# Export Attestation Prep — PREP-EXPORT-ATTEST-75-002

Status: **Ready for implementation** (2025-11-20)
Owners: Exporter Service Guild
Scope: Wire attestation export bundles (74-002) + CLI workflows (75-001) into full offline kit and mirror bundle distribution flows.

## Dependencies
- 74-001/74-002 bundle + kit layout.
- CLI verify/import contract: `docs/modules/export-center/prep/2025-11-20-export-attest-75-001-prep.md`.

## Distribution/kit contract
- Place attestation bundles and checksum files into offline kit (same layout as 74-002) and publish to mirror locations used by ExportCenter air-gap profiles.
- Provide `manifest-offline.json` entry per kit:
```json
{
  "kind": "attestation-kit",
  "kitVersion": "v1",
  "artifact": "attestations/export-attestation-bundle-v1.tgz",
  "checksum": "checksums/attestations/export-attestation-bundle-v1.tgz.sha256",
  "cliExample": "stella attest bundle verify --file attestations/export-attestation-bundle-v1.tgz",
  "importExample": "stella attest bundle import --file attestations/export-attestation-bundle-v1.tgz --offline",
  "rootHash": "sha256:...",
  "createdAt": "2025-11-20T00:00:00Z"
}
```
- Copy the kit directory to mirror/air-gap repo: `mirror/export/attestations/{kitVersion}/` with same bytes; publish `manifest-offline.json` and `.sha256` for the manifest.

## Acceptance criteria
- Offline kit includes attestation bundle + checksum + manifest entries; hashes match originals from 74-002.
- Mirrors deliver identical bytes (bit-for-bit) across environments; manifests list CLI commands for operators.
- No rebuild of attestation bundle during distribution; only copies allowed.

## Handoff
- Implement packaging/copy steps in ExportCenter build pipeline and mirror publisher.
- Update Sprint 0162 Delivery Tracker entry P9 when complete.
