Module mapping 

Explicit mapping boundary between snapshot wrappers and canonical core models.

This module centralizes snapshot validation and run payload mapping so that snapshot persistence remains a strict projection of core semantic truth.

Enums

SnapshotMappingError

Typed mapping and validation errors for snapshot/core parity enforcement.

Constants

SNAPSHOT_SCHEMA_VERSION

Current snapshot schema version accepted by the explicit mapping boundary.

Functions

map_core_run_to_snapshot

Maps a canonical core run payload into the snapshot wrapper.

map_snapshot_attempt_history

Maps snapshot attempt history entries into reducer attempt history entries.

map_snapshot_lease_metadata

Maps snapshot lease metadata into reducer lease metadata.

map_snapshot_run_history

Maps snapshot run history entries into reducer history entries.

map_snapshot_run_to_core

Maps a snapshot run wrapper into a canonical core run payload.

validate_snapshot

Validates full snapshot parity and mapping invariants before bootstrap.
