Snapshot

Status: Design/Planning Source: N/A (cross-cutting concept) Owner: Platform Team

Purpose

Snapshot defines the knowledge snapshot model for deterministic, point-in-time captures of StellaOps data. Enables offline operation, merge preview, replay, and air-gap export with cryptographic integrity.

Components

Concept Documentation:

merge-preview.md - Merge preview specification
replay-yaml.md - Replay YAML format and semantics

Snapshot Types:

Advisory snapshots (Concelier ingestion state)
VEX snapshots (VexHub distribution state)
SBOM snapshots (SbomService repository state)
Policy snapshots (Policy Engine rule state)
Task pack snapshots (PacksRegistry versions)

Implementation Locations

Snapshot functionality is implemented across multiple modules:

AirGap - Snapshot export/import orchestration
ExportCenter - Snapshot bundle creation
Replay - Deterministic replay from snapshots
Concelier - Advisory snapshot merge preview
All data modules (snapshot sources)

Dependencies

AirGap (snapshot orchestration)
ExportCenter (bundle creation)
Replay (snapshot replay)
All data modules (snapshot sources)

Merge Preview: ./merge-preview.md
Replay YAML: ./replay-yaml.md
AirGap: ../airgap/
ExportCenter: ../export-center/
Replay: ../replay/ (if exists)
Offline Kit: ../../24_OFFLINE_KIT.md

Current Status

Snapshot concepts documented in merge-preview.md and replay-yaml.md. Implementation distributed across AirGap (export/import), ExportCenter (packaging), and Replay (playback) modules. Used for offline/air-gap operation.
