Add statistical power review assistant

[Davidrsdiaz]

/claim #13

Summary

• Adds a distinct statistical power and sample-size adequacy review assistant for AI-Assisted Research Tools.
• Evaluates manuscript claims before AI review summaries endorse them by checking planned power, prospective sample-size justification, effective sample size after attrition/exclusions, subgroup/event-count adequacy, effect-size source fit, and endpoint hierarchy alignment.
• Emits reviewer remediation actions and deterministic JSON, Markdown, SVG, and MP4 artifacts from synthetic manuscript data only.

Non-overlap

This is a statistical power and sample-size adequacy review slice. It is separate from methods reproducibility, reporting-guideline validation, multiple-comparison checks, unit consistency, figure/table evidence grounding, novelty/similarity review, protocol/preregistration deviation, ethics/data availability, missing-data sensitivity, biomethods provenance, certainty/tone calibration, and lay-summary safety slices.
