class CodeScanResult(Base):
"""
Persists the result of an AI-powered code repository scan to the database.
Why this exists:
- Previously, code scan results were stored in a plain Python dict (scan_store)
in memory. This caused data loss on every server restart and prevented the
chat feature from working reliably. This model fixes that permanently.
Columns:
- id: UUID primary key, used as the scan_id returned to the client.
- user_id: Optional FK to users table. NULL for unauthenticated scans.
- repo_url: The GitHub repository URL that was scanned.
- summary: The AI-generated executive summary of the scan.
- issues: JSON list of VulnerabilityIssue dicts.
- created_at: Timestamp of when the scan was performed.
