pm(half-states): H19 founds every verdict on the set it judges

H19 resolved `Blocked-by:` targets over the body∪comment union and judged
against the body's set, but the UNJUDGED branch sat on the RESOLUTION step:
a target superseded in the body and unreadable in the archive could still
veto the verdict, producing a row no correct action by the card's owner
could ever clear.

Both founding states are now taken over the judged set. What the archive
still does — and must, per #11747 — is withhold: an OPEN target it names
still refuses a discharge, and an UNREADABLE one refuses a FULL discharge
and is named in its own clause.
