ConvMemory v3 adds a validity context layer to detect and surface update evidence in retrieved memories through target-conditioned relation verification. This mechanism sits after the standard retrieval path and uses a dual-evidence gate to score (target, source) pairs based on specific propositions.

  • The core mechanism is a dual-evidence gate conditioning a relation judgment on the specific target proposition, scoring pairs via MiniLM and DeBERTa-v3 slot heads.
  • On a synthetic multi-hop validity benchmark, the gate achieves 90.12% +/- 1.73 accuracy.
  • Through a real-data feedback loop training on synthetic pairs, the verifier reaches 98.8% +/- 0.9 group-all-correct in Memora role binding with zero target-side labels.
  • A context mode preserves retrieval by default while attaching structured validity metadata, keeping candidate sets and rank orders fixed.
  • A query-conditioned demote mode raises current-active H@1 from 45.1% to 95.7% +/- 1.2 while protecting non-superseded memories at 99.4% recall.

The layer preserves retrieval by default but offers an explicit opt-in for dense current-state workloads, ensuring that updated information is prioritized without losing access to valid historical context.
