Returns a report of Section Coach program engagement including onboarding, progress, and completion. Supports JSON and CSV output. When include_skills or include_use_cases is true, additional dynamic columns are included.

Legacy path: this report was previously served at /v1/reports/profai. That path remains fully supported and returns identical data, so existing integrations do not need to change. New integrations should use /v1/reports/coach.

Terminology: what this endpoint calls "skills" (the SKILL_* CSV columns and skill_* JSON fields surfaced by include_skills) are now called superpowers in the product. The field name is kept for backwards compatibility.

from / to scope: the date range filters the user row set by program completion date. Users whose program completion falls within [from, to] are returned; their per-superpower columns show each user's lifetime completion date for the superpower, regardless of the requested window. To query completions of a specific superpower within a date range, use /v1/reports/employee-superpower-map instead.
