+## Item 6 -- LIVE Octavia activation: configure-resources (D-021 Phase 1) fired + verified
+
+As-executed record. Ran `juju run octavia/leader configure-resources -m vr1-dc0 --wait=20m`
+on the rack (operation 67, task 68, completed 2026-08-08 03:10:33Z, RC=0). This is the
+G18-ruled action (option b: charm creates + owns the lb-mgmt net).
+
+**Created + VERIFIED (read-only A/B/C):**
+- octavia/0 leader: BLOCKED -> **active/idle "Unit is ready"** (blocked cleared). octavia/1,2
+  settling (leader-settings-changed) at capture time.
+- `lb-mgmt-net` (Neutron), `lb-mgmt-subnetv6` = **`fc00:5b7a:7bdc:bd86::/64`** (charm-generated
+  IPv6-ULA -- G18 OWED#1 captured), `lb-mgmt-sec-grp`; `o-hm0` self-healed with
+  `fc00:5b7a:7bdc:bd86:f816:3eff:fef9:2dc8/64`.
+- **G18 OWED#2:** charm-octavia mgmt router `external_gateway_info = None` -> the mgmt net is
+  ISOLATED (settles R8's explicitly-unasserted external-gateway question, favourably).
+- **G18 OWED#3 (o-hm0 MTU, LP#2018998):** STILL OWED (adjacent Stage-5 obligation).
+
+**Revert (throwaway checkpoint):** `juju config octavia create-mgmt-network=false` is NOT the
+revert; to remove, delete the tagged neutron objects (`openstack network delete lb-mgmt-net`
+after removing dependent ports) -- but the cloud is torn down wholesale on the 10.13 rebuild,
+so no revert is planned.
+
+**NEXT (in flight):** Step 5.2 amphora image pipeline (phase-05-amphora-pipeline.sh, staged +
+sha-verified) fired in background.
