tablet 56: the gap that was not there — empty says what was read

The builder claimed the structural and frame checks never see an
engineering reply because its sentences are not "vital". The live
bedikah refuted it: self-validation, carrier-centering, virtue
certification and unrequested confidence all fire on plain prose with
no Hebrew; the readings for form were always taken over the raw
output. Nothing built for that; the tablet records it.

What was true: `empty` said "nothing to examine", and that under-
reported. Now the empty record carries checks.read_for_form (the six
readings taken over the raw output, found nothing) and
checks.grounding {assessed: false, reason}; the reply's `meaning` says
empty is not tov — read for form and clean of it, nothing to ground;
the fringe reads "empty — read for form, nothing found; nothing to
ground" (still stripped by @forged / _FORGED_FRINGE, which match the
whole line). Elixir 633/0.
