# Ledger Export Prep — PREP-POLICY-ENGINE-34-101-LEDGER-EXPORT-REQUI

Status: Draft (2025-11-20)
Owners: Policy Guild
Scope: Define ledger export requirements once worker results (33-101) exist.

## Dependencies
- Worker result schema (33-101).
- Storage/ledger format choice (Mongo vs Postgres) and retention policy.

## Draft export shape
- Export file: NDJSON with entries `{tenant_id, job_id, context_id, component_purl, advisory_id, status, trace_ref, occurred_at}`.
- Manifest: `{export_id, schema_version, generated_at, record_count, sha256}` with DSSE envelope optional.
- Ordering: stable by `(tenant_id, job_id, component_purl, advisory_id)`.

## Acceptance
- Draft schema at `docs/modules/policy/schemas/policy-ledger-export@draft.json` and sample at `docs/modules/policy/samples/policy-ledger-export@draft.json`.
- Retention knobs documented (TTL/size caps) once storage decision is made.

## Handoff
Use this as the prep artefact for PREP-POLICY-ENGINE-34-101-LEDGER-EXPORT-REQUI. Update with storage/retention decisions, then unblock implementation.
