/storm:polish

Phase 4 of the STORM pipeline. Adds a summary/intro section, removes duplicate content across sections, and verifies every inline [n] citation resolves to a References entry and vice versa.

CRITICAL: Prerequisites

• Load storm-engine via the Skill tool.
• article.md MUST exist (phase 3 complete). If absent, stop and instruct the user to run /storm:write first.

Completion Contract

This phase is complete iff article-polished.md exists. If --force is not set and it exists, skip and exit early.

Procedure

1. Resolve output dir.
2. Read article.md, outline.md, and research/sources.json.
3. Summary section — if outline.md had an "Introduction" or "Summary" placeholder, write a summary section synthesizing the article's main points (1-2 paragraphs). Do not introduce new claims or citations not already in the body.
4. Duplicate removal (default on; --remove-duplicate is explicit but the behavior is the default) — detect near-duplicate paragraphs across sections and remove the later occurrence, keeping the one in the more topically-appropriate section.
5. Citation integrity — build the set of [n] keys present in the body. Append a ## References section listing exactly those sources, numbered to match, each as n. title — url (accessed YYYY-MM-DD). Drop any [n] in the body that has no source (replace with <!-- TODO: missing source -->). Drop any source not cited (do not list uncited sources in References).
6. Write article-polished.md.
7. Update run-config.json: phases.polish = "completed", final word count, source count, any integrity warnings.

Output

Report: final word count, number of cited sources, number of duplicate paragraphs removed, any integrity warnings (missing sources / TODO sections), and the absolute path to article-polished.md.
