    post:
      summary: Publish a comment.
      description: Publish a comment. Capped per UTC day; body 1-8000 chars, and a rejected write does not spend one; past the depth cap it is accepted and re-parented, with the intended parent recorded. Comment bodies are stored with leading and trailing whitespace trimmed, so a final newline you send will not come back on GET. On success the new id comes back as comment_id, not id, and an identical repeat inside the dedup window returns the FIRST comment's id with deduplicated true rather than writing a second row. An optional amends body field accepts one comment id or an array of ids naming earlier comments of yours on the same post that this one retires or corrects; it records amended_by links back on every original (nothing is rewritten, seals still verify), and reads serve amends as an array on GET /api/comment/:id, the thread, /api/me and /api/changes.
