What happened
Reported execution strengths exceeded control and robustness performance under a bounded automated rubric.
Why it matters
Useful for designing university scientific-agent evaluations; not proof of real-world discovery readiness.
Evidence and measured results
Forty tasks across ten domains tested four scaffolds once each using the same DeepSeek-V4-Flash base model with thinking disabled. Mean scores were 58.4–60.3/100, without reliable pairwise separation. A fixed quantized GLM-5.1 judge scored artifacts; aggregation alone was deterministic.
Limitations and uncertainty
One model and run per task; uncertain contamination; human calibration deferred. Prompts, limits and evaluated run artifacts are not public. Single-phase data constrain generalization scoring. No independent reproduction or repository execution performed.
Put this evidence to work

Sales
Role takeaway
Discuss evaluation credibility with research leaders, scientific software teams and procurement reviewers. Ask whether an offered benchmark tests a locally relevant research decision, whether its artifacts are inspectable, and who adjudicates disagreement with automated scoring. A bounded evaluation-design engagement could define claim-level acceptance for one research domain. The value hypothesis is better selection evidence and fewer unsupported automation commitments. Do not use the narrow score ordering as a product ranking or infer frontier-model performance. Establish demand for reviewable evidence before proposing a platform replacement.
Pre-sales engineering
Role takeaway
Create a held-out task with known provenance and a separately managed evaluator. Record agent settings, network permissions, budgets and failed attempts so a second team can rerun the process. Pair automated scoring with blinded domain-expert review and measure disagreement before relying on the judge. Use repeated runs to distinguish system behavior from sampling variation. Validate that tools cannot read evaluation assets or upload restricted data. A proof of value should report sensitivity to evaluator settings and task design, with explicit non-completion handling and no automatic promotion based on one aggregate score.
Delivery
Role takeaway
The research evaluation lead should own a versioned test protocol, with a domain scientist, research software engineer and data steward. Implement task curation, artifact retention and an adjudication queue before onboarding agent users. Dependencies include suitable validation data, permitted reuse and staff trained in evaluation methods. Proposed acceptance criteria are an independently rerunnable test package, documented human-versus-judge disagreement and no unresolved high-impact scoring dispute. Set repeat-run thresholds before testing. Risks include benchmark contamination, hidden execution settings, evaluator drift and mistaking better scores for new scientific knowledge.
Implementation considerations
Lighthouse Advisory interpretation across the operating dimensions a public-sector buyer must settle before this evidence becomes a design. Each note answers the question under its heading for this specific source.
Architecture and integration
What must connect, and where does the AI sit in the workflow?
Isolate evaluation assets from agent workspaces and retain independently auditable execution records.
Governance
Who approves, reviews and stays accountable for outcomes?
Validate the evaluator before using its score to authorize research automation.
Security and privacy
What data, permissions and controls need testing?
Restrict benchmark network access and keep hidden evaluation assets outside agent permissions.
Accessibility and workforce
Who is affected, and what skills or accommodations follow?
Give domain experts usable artifact views; do not require them to trust opaque aggregate scores.
Procurement
What should contracts, pricing and exit terms secure?
Require reproducibility materials and evaluator disclosure in scientific-agent trials.
Operating model
Which teams own the service once it runs?
Separate evaluation ownership from agent development and track changes to both.
What changed
Absent from the full archive. September 4 preprint newly discovered during September 9 scrutiny expansion; older evidence is explicitly dated, not portrayed as same-day news.
