docs(6205): inception and family comments drop record, milestone and date citations

inception states the legacy stamp and the retired rulebook keys as facts
about stored records; family keeps the repeat-trigger calibration numbers
without the date and record they were measured on, and drops the instance
that taught the per-kind comparison.
