Install the Criterion Before the Argument
Applies to a contested question that has not been argued yet - a meeting about to start, a test about to run, an escalation just received, a proposal about to be written. Peter moves first to fix the criterion, the boundary or the posture, before anyone argues the substance. The consistent effect, named explicitly in the 2026-07-29 observation, is that the other party cannot win by being more persuasive on the merits, because the merits are no longer the axis. Distinct from Reclassify to Route in mechanism: that pattern reassigns who owns a question, this one controls WHEN the criterion lands relative to the debate. The two frequently co-occur. Mined from 7 independent observations between 2026-01-20 and 2026-08-31.
