Inspect changes over time and evaluate updates. Usage: /semantica:change <task> [args]
$ARGUMENTS = task + optional node, time window, or filter.
diff [--from <ts>] [--to <ts>] [--node <id>]
Compute graph diffs between two snapshots.
from semantica.provenance.change_tracker import ChangeTracker
from semantica.context import ContextGraph
tracker = ChangeTracker()
diff = tracker.compute_diff(from_ts=from_ts, to_ts=to_ts, node_id=node_id)
Output: added/removed nodes and edges, attribute changes, and impact summary.
