E.3.9.1 prerequisite. Rules R0031-R0040 now use lifter:behavioral_*,
R0041 (open_relay) uses lifter:email_open_relay; the rest of the email,
canary, and intel cohorts already conformed. Each lifter at E.3.9-E.3.12
will claim its rules via str.startswith('lifter:<owner>_'), keeping the
ownership routing explicit and trivially extensible.
R0001-R0006 / R0030 lifter:* rules are E.3.13 (Identity/Credential)
territory and stay as-is.
