Database schema — `cro.*` ERD

The canonical data model. Tables are color-coded by category: regulated tables carry provenance and require a Part 11 signature to promote staging → live. Click any table in the diagram to jump to its details card below, or open `/schema?table=study` to deep link.

Foreign keys

Regulated tables

Regulated9

Carries created_at / updated_at / created_by / provenance_id. Promotion requires a Part 11 signature.

Staging2

Where agents land their writes. State machine: proposed → reviewing → signed → promoted.

Audit2

Append-only provenance and ops logs. Not part of the regulated write path.

Reference2

External or read-only data we index but do not own.

cro

provenance_event

Append-only ALCOA+ provenance spine. Every regulated action emits a row here before any write. Inspectors join through subject_kind/subject_id to reconstruct chain of custody.
