Operator utterance, verbatim: "I want it to use IPv6, if there is spam
mechanisms being applied then that is bad. Even if it doesn't cause an issue
now, it might in the future. A clean IPv6 network is better than one with
unusable and possibly future breaking configurations."

That stated a PRINCIPLE rather than selecting an option, so a confirming
exchange was taken rather than adopting an inferred ruling (GA-R5 forbids
adopting from an inferred or reconstructed ruling). Confirming utterance,
verbatim: "Yes -- keep the v6 legs, remove only the option".

Recorded as a D-101 RULING NOTE dated 2026-07-31. OPS under GA-R3 -- a
renderer + gate change, doubt resolves DOWN, no D-number assigned. D-101's
family matrix is UNAMENDED: the dual-stack posture does not change and every
v6 VIP leg is retained.

Effect: barbican, designate, magnum, octavia, placement and vault keep all
three v6 VIP legs each; prefer-ipv6 stops being emitted for them; both DCs,
symmetric.

The SEVEN charms that DO declare the option are NOT covered by this ruling
and were deliberately not bundled into it -- one decision per exchange.

Committed and pushed BEFORE any dependent work.
