Reproduce the analysis, not a conclusion.Each notebook keeps its declared dataset, entity universe, period, source custody, and interpretation boundary. Recipes never combine unlike metrics into a composite market-power score.

Research handoff

From public rows to reviewable evidence.

Every notebook keeps the endpoint grammar visible, checks the fields it consumes, produces one bounded figure, and routes the result back to live profiles and methods.
