Record the second Cut 6b fix batch

The harness now restores from the original bytes on every path and checks
its own round trip before it writes; dotted roots and the reader's root-kind
check have tests and mutations; the local bound is one named constant. The
Cut 6 entry notes name the entries that actually pin their rules.
