Competitor Ingest DB Snapshot Governance (CM3)

Status: Draft · Date: 2025-12-04 Scope: Enforce database snapshot governance including versioning, freshness SLA, and rollback procedures for imported external feeds.

Objectives

Define versioning scheme for imported snapshots.
Establish freshness SLA for external data.
Enable deterministic rollback to previous snapshots.
Support audit trail for all snapshot operations.

Snapshot Versioning

Version Scheme

{tool}-{timestamp}-{sequence}

Examples:
- syft-20251204T000000Z-001
- trivy-20251204T120000Z-001
- clair-20251204T060000Z-002

Snapshot Record

{
  "id": "syft-20251204T000000Z-001",

Freshness SLA

Thresholds by Tool

Tool	Max Age	Stale Threshold	Critical Threshold
Syft	7 days	14 days	30 days
Trivy	7 days	14 days	30 days
Clair	7 days	14 days	30 days
Custom	Configurable	Configurable	Configurable

Freshness States

State	Condition	Action
`fresh`	age < max_age	Normal operation
`stale`	max_age <= age < critical	Emit warning
`critical`	age >= critical	Block queries without override
`expired`	Manual expiry	Data unavailable

Rollback Command

# Rollback to previous snapshot
stellaops ingest rollback --tool syft

# Rollback to specific snapshot
