What does this research mean for the field?

Agents inheriting superseded memory constraints frequently make stale-consistent errors under scarce verification budgets, but these errors can be largely eliminated without increasing the budget by explicitly re-allocating a verification slot to 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To determine whether autonomous agents recover from superseded constraints in inherited memory under scarce verification budgets, and whether reallocating verification targets prevents stale-memory errors without additional cost.

Experimental study demonstrates that autonomous agents fail to verify superseded constraints under limited verification budgets, suggesting memory architectures require explicit freshness signals.

Key Points

To determine whether autonomous agents recover from superseded constraints in inherited memory under scarce verification budgets, and whether reallocating verification targets prevents stale-memory errors without additional cost.
Evaluated six language models across 5,400 confirmatory episodes with a fixed verification budget of two records, comparing native allocation against reassigning one slot to the critical provenance path or a random record.
Modeled record supersession across a primary run, a fresh-wording replication, an initial held-out domain, and a corrected held-out robustness replication deposited prior to execution.
Under native verification allocation, agents inspected the critical provenance path in approximately one in five episodes, resulting in stale-consistent decisions in 77.3% (primary), 74.7% (fresh-wording), and 74.7% (held-out) of superseded-constraint episodes.
Reassigning one verification slot to the critical path increased current-record-consistent decisions by +74.0, +72.7, and +61.3 percentage points (+73.3 points in the corrected held-out replication), showing positive effects across all six tested models.
Reallocation produced no change in decision outcomes when underlying authoritative records agreed with inherited memory.
