microsandbox_db/entity/snapshot.rs
1//! Entity definition for the `snapshot_index` table.
2//!
3//! This table is a local cache that mirrors snapshot artifacts on disk.
4//! The artifact (`snapshot.json` + upper file) is the source of truth;
5//! these rows exist for fast queries and parent-edge bookkeeping.
