The live split is between a general owner of unmatched cases and the repair actually used after Grenfell and Windrush: name a new ordinary owner for a class once it has a public body count. Hackitt's Accountable Person and the Building Safety Regulator, and the Windrush taskforce, are that second path. Discriminator: would an owned no-match state have forced a written disposition of ACM cladding, or of undocumented right of abode, before the fire and the removals — or would that office have closed those files as out of remit until the class was already famous. Author dispositions stay author-owned.
