MADB 0.2.13 remembers what is still true.
Agent memory now models change as evolution—not a pile of contradictory facts.
Temporal validity
Replace stale facts without erasing history.
# the API changed supersede(old_event_id, by_event_id) # normal recall returns current truth recall(query="production API") # → api-v2 # historical recall remains honest recall(query="production API", as_of=T) # → api-v1

Stable public tools
Temporal validity, export and causal landscape join the existing memory surface.
Event-preserving export
Move the store without losing stable event identities.
Clear product boundary
Current-truth recall is free; enforced enterprise revocation remains a paid capability.
Try the failure case
Verify it with your own agent.
Store a fact, replace it, and confirm current recall no longer returns the stale version. Then use as_of to reconstruct the earlier state.
