Section Logic Polisher (thesis + argument bridges)

Purpose: close the main “paper feel” gap that remains even when a subsection is long and citation-dense:

• missing/weak thesis (paragraph 1 never commits to a claim)
• weak inter-paragraph flow (paragraph islands; no content-bearing bridges)

This is a local, per-H3 polish step that happens after drafting and before merging.

Note: if the main problem is paragraph-count overgrowth, run paragraph-curator after this check. It only merges adjacent paragraph boundaries and preserves all prose; semantic redundancy still belongs to the owning writer.

What this skill blocks on (and what it does not)

Blocking (must fix):

• paragraph 1 lacks an explicit thesis / takeaway (a content claim)
