- HA Sofia token: auto-bootstrap from Vault secret/viktor/haos_api_token when
HOME_ASSISTANT_SOFIA_{URL,TOKEN} env vars are unset. Default URL =
https://ha-sofia.viktorbarzin.me.
- cert-manager: add cert_manager_installed() probe (kubectl get crd
certificates.cert-manager.io). When not installed — which is our current
state — report PASS "N/A" instead of noisy WARN "CRDs unavailable".
- LVM snapshot freshness: grep pattern was `-- -snap` but actual LV names use
underscore (`foo_snap_YYYY...`), so the grep matched nothing and the check
always WARN'd. Fixed to `grep _snap`.
After fix: PASS 36→40, WARN 9→6, FAIL 1→1 (new ha_entities FAIL is a real
HA issue, not a script bug — 400/1401 sensors stale on ha-sofia).
