## Summary

A team of researchers introduced a prospective term for personal memory retrieval that requires no inference at query time. Commitments are stored in an explicit ledger and linked to memory items, giving them a multiplicative salience boost that is blended into embedding‑based retrieval. In a synthetic task set modeled on TriggerBench (48 blind‑authored dialogues, 175 tasks), recall@5 rose from 0.000 to 0.955 at the default blend weight and reached 1.000 under a floor variant, with zero false boosts across 53 resolved‑commitment tasks. The authors observed that only 17‑29% of naturally phrased commitment‑trigger pairs defeat embedding similarity, meaning the term helps in a minority of cases while causing no harm elsewhere. Results are preliminary, the evaluation set was author‑constructed, and testing on the official TriggerBench data is planned for future work.

## Key points

- New prospective term adds zero‑inference linkage to personal memory retrieval, boosting recall@5 from 0.000 to 0.955.
- On 48 synthetic dialogues (175 tasks), the method achieved up to 1.000 recall with no false boosts across 53 commitment tasks.
- Authors note results are preliminary, using a self‑constructed dataset; real‑world performance on TriggerBench remains untested.

## Why it matters

If reliable, zero‑inference prospective linking could let personal assistants anticipate future actions without extra compute, improving user experience and privacy.
