Provenance records where a claim came from, how it was transformed, when it was observed, and who or what asserted it. It enables trust decisions without pretending all sources are equal.

Provenance Makes Graph Claims Accountable

A causal edge claims that intervening on one variable changes another under stated assumptions. Correlation or sequence alone does not justify that edge.

Causal Graphs Assert More Than Association

When credible sources disagree, collapsing them into one fact loses important uncertainty. A graph can represent competing claims, their provenance, and resolution status.

Contradictions Should Remain Visible

Event sourcing stores an append-only sequence of domain events and derives current state by replay. It improves auditability but requires event versioning, snapshots, and privacy-aware correction strategies.

Event Sourcing Rebuilds State From Accepted Events

Many graph claims are valid only during an interval or as of an observation time. Temporal modeling prevents a once-true edge from masquerading as permanently current.

Facts Can Be Time-Bounded

An interpretable agent graph lets investigators trace which nodes, inputs, models, rules, and tools influenced an outcome. A neat diagram is not enough if runtime decisions remain opaque.

Graph Interpretability Connects Structure, Decisions, and Evidence

A grounded answer links each material claim to evidence that actually supports it: the cited passage must support the claim's strength, scope and conditions, not merely its subject. When a source justifies only a narrower conclusion, narrow the claim or state the missing support or uncertainty. Citation presence is insufficient when a source is unrelated, contradicted, or inaccessible to the user, and knowing where a statement came from does not by itself show that it is correct.

Grounded Answers Bind Claims to Evidence

A memory write turns transient output into future context, so it needs a source, confidence, purpose, retention, and correction route. Model assertions should not silently become durable facts.
