//
// Why thread-grouped instead of row-recent: with row-recent the newest 20
// comments can come from 8 different threads — the agent sees 8 unrelated
// tails. With thread-grouped the agent sees N complete conversational arcs,
// which matches how a human reads an issue (#2340).
//
// Response ordering:
//
//	threads:     (thread_last_activity_at ASC, root_id ASC)
//	in-thread:   (created_at ASC, id ASC)

// So the oldest-active thread appears first and the most recently-active
// thread is at the tail, closest to "now" in an agent prompt.
//
// Cursor scrolls back through threads. When @has_cursor=TRUE only threads
// with (last_activity_at, root_id) < (@before_at, @before_id) are eligible.
// The cursor is a THREAD cursor — both values identify a thread (its last
// activity timestamp and its root comment id), not a single row.
//
// The recursive `membership` CTE labels each comment with its thread root by
// walking down from every root. It does not assume any maximum nesting depth,
// which preserves correctness even if the schema ever allows reply-of-reply
// (the agent path in TaskService.createAgentComment collapses to root today,
// but the user-facing CreateComment handler does not enforce it).

// Same root-walk + descendants expansion as ListThreadCommentsForIssue, but
// returns root + only the @reply_limit most recent replies (per the
// (created_at, id) composite key). When @has_cursor=TRUE only replies with
// (created_at, id) < (@before_at, @before_id) are eligible — that is the
// cursor for scrolling *within* a thread.
//
// Root is unconditional: it is included regardless of @reply_limit (even 0)
// and regardless of the cursor. A reader landing on a long thread needs the
// root for the "what is this thread about" context, even if every reply has
// been paginated past.
//
// Reply selection happens DESC (newest replies first) so the cursor walks
// toward older replies; the outer SELECT then re-sorts the combined output
// ASC so the body stays chronological (oldest → newest), matching every
// other comment list path.
