A run is the one record of what a Self or a Persona turn took on: key
<instance>:run:<label>, claims of CutSpec, Finding or FollowUp only (refused at
validate), a canonical-decimal budget, turn PersonaTurn or SelfRun per ruling
every-wake-a-run. The run sample is appended at the end of samples(); the golden
gains one line after sample.hand_off and no existing line changes. The
schema and its catalogue entry are derived from the type. No existing kind or
field is touched; the epoch stays v2.
