ADR-0011: File Store Integration

Status: Accepted
Related: ADR-0005 Event Store Schema, ADR-0006 Event Envelope

Context

Large artifacts (FITS, calibrated images) must not bloat event store.

Decision

• Store digest references (sha256) in events.
• Actual files live in CALISTA’s content-addressable file store.

Consequences

• Event store remains lean.
• Provenance preserved by digest integrity.
