Section Merger

Goal: assemble a paper-like output/DRAFT.md from:

• sections/ (per-section/per-subsection prose)
• outline/transitions.md (short hand-offs; generated by transition-weaver)
• outline/tables_appendix.md (reader-facing Appendix tables; generated by appendix-table-writer)

Merge order is driven by outline/outline.yml. The draft title is taken from GOAL.md when present. sections/sections_manifest.jsonl is an optional diagnostics input.

This skill is deterministic: it does not rewrite content or invent prose; it only merges already-generated artifacts.

Transitions (injected text)

• By default, section-merger inserts only within-chapter H3->H3 transitions.
• Optional: if you want between-H2 transitions inserted too, create outline/transitions.insert_h2.ok in the workspace.
• Format contract: only lines matching - 3.1 -> 3.2: <text> are injected by default.
• Compatibility: → is accepted, but -> is the preferred contract (avoids control-character encoding issues).
• Treat transitions as injected draft text: run post-merge-voice-gate after merging, and route fixes back to outline/transitions.md (do not patch the merged draft).
