/variable-map
Read wiki/variables/*.md, wiki/papers/*.md, wiki/datasets/*.md, wiki/models/*.md, project READMEs, and raw/notes/research-intent.md when present.
Produce a comparison table with: construct, variable role, measurement, data source, sample frequency, source papers, advantages, risks, and project availability.
Archive the result to wiki/outputs/variable-map-{slug}-{YYYY-MM-DD}.md and log it with tools/research_wiki.py log.
Constraints:
- Do not merge genuinely different measurement choices into one row.
- Do not invent database tables or project paths.
- Mark fields that exist in the literature but are missing locally as
missing from project.
