TALK's precondition reaches over a counter because the cartridge does;
its talked-ledger entry was read one tile ahead. So TALK was bound at the
counter and recorded nothing, 107 times, and the nurse was never retired.
The entry now comes from the same reading the precondition makes.
A completed HEAL writes her into the talked ledger: the macro has had the
conversation with its own presses, and the reached window would otherwise
expire in ten brain minutes and offer the ring again. A declined prompt
writes it too -- 12.4 inverted for one person, because the pad only ever
offers NO at her prompt when the party is already full.
And the general rule: a YES or NO whose prompt is up again on the same
map and tile within one hold did nothing, so that answer joins the
blocked ledger for its window.
