L2 = the standard itself (or its complete free preview, or the maker's drawing).
L1 = two or more independent sources agree: the release gate.
LO = one source only: printed amber and marked *.
c =a source value was corrected; the datasheet says how.
House convention = a detail no source dimensions, drawn to a stated house rule.
This size's values: L112 - LO 8.
