Add-only table for the one-time Haiku pass result: per atomic control x use-case
-> relevant? + sub_topic + canonical_obligation. Atom-grain successor to the
master-grain mc_use_case_mappings (master clustering = gpre2 object-only ->
mega-clusters, unusable). Runtime reads only this table (no live LLM).
