+## VERDICT UP FRONT: SPIKE STILL BLOCKED (empirically) — no probeable drill environment exists.
+
+**Two empirical attempts, both blocked (2026-07-25). Design half below stands; GO/NO-GO PENDING.**
+
+### Empirical attempt 2 (2026-07-25, PM) — the t740 was checked; there is no drill VM there.
+The operator ruled (2026-07-25) that **drill + build VMs are hosted on the HP t740 (`demo-hp`) from
+now on**, so this half was re-attempted there. Discovery (read-only, no LAN scan): the t740 = `demo-hp`
+(Tailscale `100.76.96.79` / LAN `192.168.0.87`), accessed via the hub-vaulted G1 break-glass root
+credential (`host_recovery/demo-hp-bb76ea`; secret redacted). **Findings:**
+```
+t740 (demo-hp, PVE 9.2.2): qm list → (empty); /etc/pve/qemu-server/ → empty; standalone (no cluster);
+                           only LXC guest 9201 (its OWN live demo controller). NO nested drill PVE VM.
+hub registry:              only demo-hp-bb76ea (t740) + demo-felhom-8363b5 (N100) — NO drill appliance.
+DooPlex:                   drill.qcow2 EXISTS (/mnt/5_hdd/felhom.eu/drill/, 18G) but is POWERED OFF —
+                           a GOLDEN-BAKE appliance (bake logs to 0.153.0, last Jul 18–20); its nested
+                           guest (9100) is purged after each bake, so it has no island-bridge topology
+                           (agent + nested guest + bootstrap.json) to probe. DooPlex is the production
+                           k3s node and is loaded (~17G of 62G free).
+```
+So the operator's ruling is **forward-looking and not yet realized** — no probeable drill appliance
+exists on the t740, and the only artifact is a stale bake VM on the production node. **Per the hard rule
+("do not improvise on production"), probes P2–P7 were NOT run; felhom-pve, the t740 host networking, and
+guest 9201 were left UNTOUCHED.** **Operator decision (2026-07-25): they will provision a nested-PVE
+drill VM on the t740 (agent + nested guest); this task re-runs then.** GO/NO-GO stays PENDING.
+
+### Empirical attempt 1 (2026-07-25, AM) — drill env was GONE on felhom-pve.

 **Probe 1 (drill env health check) — FAIL/ABSENT.** On felhom-pve (2026-07-25):
