//   - atomicity — the insert and the timestamp bump commit or roll back
//     together, so an issue is never left with a stale updated_at after a
//     comment persists; and
//   - tenant integrity — the comment can only be created against an issue that
//     actually exists in the given workspace. A mismatched (issue, workspace)
//     pair matches 0 rows in the CTE, the dependent INSERT then selects nothing,
//     and the :one query returns pgx.ErrNoRows. A wrong workspace can therefore
//     never leave a mis-attributed comment or a silently un-touched issue.
//
// Centralizing this here means every comment entrypoint inherits both
// guarantees regardless of what a caller passes. The "Updated date" sort and
// the daemon GC TTL both read updated_at, so this consistency is load-bearing.

// Planned ids matter for retry children because their input comments predate

//
// Author-type scope (MUL-4304): originally restricted to author_type = 'member'.
// That left a gap — an explicit agent→agent @mention (agent A comments

// the create-time enqueue path (merge only folds into a QUEUED task, so a
// dispatched target hits the merge-miss + active-task continue) and then never
// compensated here, because agent-authored comments were excluded. We now also
// return 'agent' comments so those explicit mentions can be replayed.

// This does NOT reopen the anti-loop guarantees the member-only filter was
// protecting. The reconcile pass runs each returned comment through
// computeCommentAgentTriggers under its OWN author_type, and for an agent author
// it then keeps ONLY explicit @agent/@squad mention triggers
// (keepExplicitMentionTriggers) — the assigned-squad-leader fallback and all
// other conversational routing are dropped, so a plain agent reply /
// acknowledgement yields nothing regardless of issue assignment. The reconcile
// pass further keeps only triggers routing to the agent that just completed, so

// (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.
