Current Implementation

erDiagram
    JOBS ||--o{ JOB_EVENTS : logs

    JOBS {
        int JobId PK
        string Status
        datetime CreatedAt
        datetime UpdatedAt
        json ResultJson
        text ReportMarkdown
    }

    JOB_EVENTS {
        int Id PK
        int JobId FK
        datetime TsUtc
        string Level
        string Message
    }

Current audit capabilities:

• Job creation and completion timestamps
• Job execution events (start, progress, errors)
• No entity-level versioning
• No user attribution (no user system)

Target Architecture (Future)

erDiagram
    USERS ||--o{ EDITS : makes
    CLAIMS ||--o{ EDITS : tracks
    EVIDENCE ||--o{ EDITS : tracks
    SOURCES ||--o{ EDITS : tracks
    KEY_FACTORS ||--o{ EDITS : tracks

    USERS {
        uuid id PK
        text name
        text email
    }

    CLAIMS {
        uuid id PK
        text text
    }

    EVIDENCE {
        uuid id PK
        uuid claim_id FK
    }

    SOURCES {
        uuid id PK
        text name
    }

    KEY_FACTORS {
        uuid id PK
        uuid claim_id FK
        text question
    }

    EDITS {
        uuid id PK
        text entity_type
        uuid entity_id
        uuid user_id FK
        text change_type
        boolean is_automated
        jsonb changes
        text reason
        timestamp created_at
    }

Target features:

• Full entity versioning (Claims, Evidence, Sources, KeyFactors)
• User attribution for all changes
• AKEL vs human edit distinction
• Hot/cold storage tiering (PostgreSQL + S3)
