tisserande.tracking.backends

Pluggable storage backends for provenance records.

The TrackingBackend protocol defines the interface; concrete implementations include LocalSyncBackend (real DB) and NullBackend (no-op for testing).

Classes

TrackingBackend	Protocol for provenance storage backends.
LocalSyncBackend	Uses tisserande.local_sync to store provenance in the local DB.
NullBackend	Discards all provenance. Useful for testing or disabling tracking.
