+### 2026-07-08 (addendum 40, jumphost stream) -- devteam cluster NoValidHost diagnosed (capacity, not quota); decommission audit + recommendations (no numbers consumed)
+
+Read-only diagnosis + audit; the only mutation this window was the operator's
+own delete of the wedged cluster. Nothing agent-executed.
+
+- **TestCluster CREATE stall root-caused:** devteam 1+3 gp.mid cluster
+  (created 00:18, CAPI driver); control plane + 1 worker ACTIVE, workers
+  2-3 ERROR with nova fault "No valid host was found" (verbatim, by UUID --
+  admin name-lookup is project-scoped, same trap as template show). NOT
+  quota (4x gp.mid = 8 cores/32768MB vs 10/20/51200 limits; quota rejects
+  at the API, never lands ERROR). Physical RAM was the limiter: free
+  ~3.4/8.5/7.5 GB across the 3 hypervisors; gp.mid=8192MB, so after 2
+  landed no host could fit another. Operator deleted TestCluster;
+  devteam re-created as TestCluster2 1+1 (the fitting shape; matches
+  stage6/H2). Also noted: cluster was built from a GUI template
+  "TestTemplate", not the walkthrough's "test1".
+- **FINDING (logged, unruled): tenant quota over-promises testcloud
+  capacity** -- devteam hit NoValidHost at under 2/3 of its RAM quota
+  (51200MB vs ~19GB schedulable, fragmented). Fine at Roosevelt scale;
+  misleading here. Options for a later ruling: trim testcloud tenant
+  quotas to schedulable reality, or set the expectation in clientdocs.
+- **Decommission audit (operator-requested, read-only):** cloud-wide
+  running set = 3x beta-cluster nodes, capi-mgmt-v2, 3 amphorae; zero
+  stray/SHUTOFF servers, zero volumes. Domains: 5 platform + devteam
+  (live) + beta + foil1; acme fully gone. Recommendations queued:
+  (1) lbtest LB leftover (beta): reclaim ~1GB + FIP 10.12.6.97 -- clean
+  path is kubectl delete service from beta's kubeconfig (k8s-managed;
+  direct Octavia delete would dangle/recreate), main-chat asset;
+  (2) beta-cluster teardown = the big reclaim (~17GB, doubles free RAM)
+  -- BLOCKED on the cross-stream ruling that its resize-acceptance role
+  is done (ledger marks node_count=2 deliberate);
+  (3) foil1: dormant shell (no instances/LBs/FIPs/volumes) -- RECOMMEND
+  offboard via tenant-offboard.sh (retires a live domain, closes its
+  waived Horizon rows; re-onboarding is proven cheap if a foil is needed
+  again);
+  (4) capi-mgmt-v2 and platform domains: KEEP (CAPI control plane).
