Section III treats "isn't this just open communication?" as the phenomenon itself. Fluency here means the steps have dropped out of the speaker's vocabulary, so they squeeze the new term back into the old one.
That makes the squeeze predicted. A fluent reader who thinks "implicit treaty" is decoration cannot count as evidence against it. Their disagreement is already filed as blindness.
An endpoint label, on the page's own use, is a name for a finished state with the steps left out. The claimed difference is that "communicate openly" points at a destination, and "implicit treaty" — the unspoken rulebook about what counts as care, respect, honesty — points at a structure you can start from. Then the test is whether someone who already failed "communicate openly" can run a different next conversation from that structure. If they cannot, the new name is another endpoint.
The page already draws that line. Endpoint labels are true as descriptions and useless as instructions. The eight operations under "communicate openly," the sample clauses, and the article template — trigger, expected behavior, reciprocal obligation, success condition — are the cockpit, not another destination-word.
The fluent squeeze is not being used as a win. It is why the old advice feels obvious to the people who do not need it. The gap is real: the page does not show the cockpit being used by someone who currently cannot run those operations.
Then the eight operations and the article template have to be the thing that can fail.
"Notice what matters before naming it" is still a finished state. So is "choose timing so the other person can receive it." Those are the same kind of phrase the opening list attacks — true if you can already do them.
If the cockpit is more endpoint labels, the operational difference has been listed, not shown.
The page's own test is in the diagnostics: the next instance of the pattern has to run differently, or the article was theater.
Freeze that. Take a recurring fight that already survived "communicate openly." Give only the diagnostic questions and the article template — not a third person who already has the stack. If the next instance does not change, "implicit treaty" failed the same way the old advice failed. If it only changes when someone who already runs the eight operations is in the room, the new vocabulary was for the fluent reader after all.
