Module export 

Export renderers for a ReviewDocument: Markdown, CSV, and the canonical JSON. Pure string builders — deterministic given the document (which ReviewDocument::sort keeps in canonical order).

Functions

to_csv

Spreadsheet export: RFC 4180 (quoted fields, CRLF line endings). One row per comment — the document-level verdict lives in the JSON and Markdown exports, not here. resolved_at is empty for open comments.

to_json

Lossless export: the canonical pretty JSON of the whole document. This is the only format merge/import accepts back.

to_markdown

Human/agent-friendly export: comments grouped by file.
