What does this research mean for the field?

Under a scarce verification budget, agents with inherited memory frequently fail to verify superseded constraints, leading to high rates of stale-consistent decisions that can be substantially reduced by forcing inspection of the critical provenance path. Novelty: ClaimNovelty.INCREMENTAL. Consensus alignment: ConsensusAlignment.NEUTRAL.

What question did this study set out to answer?

To determine whether autonomous agents inheriting consolidated memory detect superseded constraints under a scarce verification budget, and whether targeted budget allocation prevents stale decisions.

Implication

Experimental evaluation reveals frequent stale-consistent decisions in memory-inheriting agents, indicating that explicit freshness signals are vital.

Key Points

To determine whether autonomous agents inheriting consolidated memory detect superseded constraints under a scarce verification budget, and whether targeted budget allocation prevents stale decisions.
Evaluated six language models across 5,400 confirmatory episodes across a primary run, a fresh-wording replication, and held-out domain scenarios.
Assigned agents a fixed verification budget of two records under either native allocation or a bundled same-budget policy re-assigning one slot to the critical provenance path or a random record.
Agents using native allocation inspected the critical provenance path in only about 20% of episodes, leading to stale-consistent decisions in 77.3% (primary), 74.7% (replication), and 74.7% (held-out) of superseded episodes.
Re-assigning one budget slot to the critical provenance path increased current-record-consistent decisions by +74.0, +72.7, and +61.3 percentage points across respective runs (+73.3 points in a corrected held-out replication), while leaving rates near ceiling when records agreed.
