Get comments of a Substack post by publication (subdomain or custom domain) and numeric post id. Returns the threaded comment tree: each comment has id, text, author, created_at, depth, parent_id, reaction_count and reactions, restack_count, reply_count, and nested replies.

💡 AI Hint: Get comments on a Substack post. Identity is (publication, post_id). publication is the publication’s subdomain (e.g. platformer) or custom domain (e.g. thefp.com); post_id is the numeric post id (the id field returned by substack/posts, not the slug). Each item is a top-level comment with nested replies (a threaded tree): id, text, author, created_at, depth, parent_id, reaction_count, reactions, restack_count, reply_count, and replies. Comments may be empty when a publication restricts them to subscribers.
⚠️ Common errors: 412: Post not found, or the publication is not a valid Substack publication
