Data handling

dlogs stores only the data required to run decision capture, retrieval, and enforcement workflows: decision payloads, artifact bindings, and integration event envelopes for idempotency and replay safety.

• Append-only decision records with immutable identifiers.
• Webhook payloads retained for idempotency and replay safety.
• Source metadata (`capture_source`, optional `source_link`) for cross-surface provenance.
• Session and API-key authentication with revocation support.
