checks.grounding.ungrounded holds coupling strings ("coupled(claim(1),
not_in_sources)"), not sentences; the fringe called Access.get/3 on a
string and the first real reply from Claude through /gate/anthropic
answered 500 CHATAT_UNEXPECTED (after recording its bedikah). The
sentence is now looked up by claim index in the check's claims; a test
produces an ungrounded claim. Broken Tablets tablet 52. Elixir 593/0.
