golemcloud Snapshot restoration
Set snapshotting: Snapshot.define({ schema, policy }) and use
.implement({ init, methods, snapshot }). init(id) exclusively infers runtime state. For a common
Ref<State> whose saved value matches the schema, use snapshot: Snapshot.ref<Saved>(). For a custom
representation use { save: state => Effect<Saved>, restore: (saved, context) => Effect<State> }.
When SQLite databases are declared, add databases: state => ({ declaredName: state.handle }) to
that strategy. The runtime restores database images before constructing methods.
Use Snapshot.custom({ policy }) with implementation save/restore only for user-managed bytes.
Ordinary agents omit snapshot. External PostgreSQL, MySQL, and Ignite state is not included.
Use host-backed Durability combinators around external effects. Do not add compatibility migration
envelopes or legacy initialize/restore factories.
