Outline Refiner (Planner pass, NO PROSE)

Goal: make the outline auditable by adding an explicit planner stage that answers:

• Do we have enough mapped evidence per H3?
• Are the same few papers reused everywhere?
• Are subsection axes still generic/scaffold-y?
• Is the outline likely to produce a paper-like structure (final ToC budget: ~6–8 H2; fewer, thicker H3s)?

This is a deterministic “planner” unit: it must not write survey prose.

Inputs

Required:

• outline/outline.yml
