A weighted average hides blockers. The critical count is there to overrule it.
— /10
Release only when this clears the gate and the critical count is zero
Check the weight sum first: if it is not 1.00 the score is on a different scale from the gate and the comparison is meaningless. The weighted average is the tool's own weakness — six comfortable dimensions will carry a seventh that is not ready, and the score can clear the gate while an unresolved blocker is the thing that actually stops the order. Any dimension below the critical threshold should stop release whatever the headline says, which is what the critical count is for. The required-weakest-score output is arithmetic, not advice: a figure above 10 means no improvement in that one dimension can close the gap, and the shortfall has to come from elsewhere. Scores themselves are judgements, so record who assigned them and against what evidence — a readiness review whose inputs cannot be traced is a meeting, not a gate.
