Operator utterance, quoted verbatim in both entries: "Rule D-136 option D,
mirror the v4 octet for both legs but make a note to review at the end of the
project to review for adjustment."

GA-R5 NOTE, recorded rather than glossed: this single exchange carried TWO
rulings, and GA-R5 says one per exchange. Both recorded because each clause is a
specific unambiguous answer to a question already put -- not the template
"yes to all" the rule exists to reject. Flagged to the operator; either can be
re-put separately and re-taken.

D-136: option (D) was WRITTEN INTO the entry before being adopted, because the
directed shape matched none of the recorded (A)/(B)/(C) and adopting an option
the entry did not contain would leave a future reader unable to find what was
decided. (D) populates the apex first, then builds the renderer, then dry-runs it
without gating this deployment -- differing from (C) by closing the apex gap now
rather than hand-maintaining VIPs/bands indefinitely, and from (A) by keeping an
unproven tool off the deploy's critical path. Its validation advantage over both
is the reproduction baseline frozen earlier today. Now ADOPTED; ledger-scan
confirms it dropped off the open-decision list (4 -> 3) and the ledger's
machine-derived block is re-seeded.

IPv6 host part: mirrors the v4 octet on BOTH leg types, closing the mapping R4's
D-134 amendment left explicitly unruled -- the blocker on populating any v6
value, since the apex holds every v6 prefix and zero per-address v6 objects.
Accepted cost recorded as deliberate: the GUA leg's dedicated VIP /64 is used
from ::50 up, leaving ::1-::49 unused, in exchange for one rule per plane instead
of a per-leg special case in the renderer. Review owed at the close of THIS
deployment as forward item F4 -- whose trigger differs from F1-F3, so the section
intro now says each item carries its own trigger.
