Multiply Along the Chain

The idea
A multi-step task succeeds only if every step succeeds — and per-step reliabilities multiply along the chain, so small per-step losses compound into large whole-task failure.
In practice
Unit 6's along-a-branch rule, pointed at autonomy: the honest unit of evaluation is the whole chain, never the dazzling step.
Where people slip
Per-step brilliance is not chain reliability — the arithmetic will not be charmed.
