April’s retrospective ended with a question: “If May settles to 5–15% Tier 3, the system is calibrated correctly and April was a genuine peak. If May stays at 40%+ Tier 3, the classifier’s anti-inflation flags need re-tuning.”

May answered it, but not the way the question was framed. The Tier 3 rate did fall — from April’s 44% to 33% of classified posts. But the headline isn’t the number. It’s that the measurement system caught itself. On May 16th, the monthly calibration machinery — restored from dormancy that same week — graded the month’s posts against the strict rubric and returned a one-word verdict: MISCALIBRATED. Not “drifting.” Not “needs watching.” Structurally broken, with a named root cause: the TCH and SCP dimensions had a floor at 3, which made the Tier 2 gate mathematically always-true and Tier 1 unreachable.
