Platform log ingestion could fail silently: fluent-bit shipped to vlinsert-generic while the monitoring HelmRelease reported Ready, and a vlinsert-generic ExternalName in cozy-monitoring dead-ended at a tenant-root VictoriaLogs that did not exist when the root tenant had monitoring disabled. Logs were dropped with no failing signal. Three complementary changes: - Readiness (do not stay silently Ready): the monitoring-system HelmRelease now uses a `poller` waitStrategy and a healthCheckExpr on its VLCluster (status.updateStatus), so a missing/unhealthy log store makes the release not-ready instead of flipping Ready as soon as the CR is applied. Mirrors the seaweedfs CNPG pattern. - No empty-log-store hole: system/monitoring rejects an empty logsStorages at render time (helm fail). With no entry no VLCluster is created, the readiness gate has nothing to match, and fluent-bit would silently drop logs — so this is made a loud misconfiguration rather than a documented footgun. - No silent fallback: the cozy-monitoring -> tenant-root vlinsert/vminsert ExternalName redirects in cozystack-basics are now created only when the root tenant hosts monitoring, gated on _cluster.monitoring-enabled — fed from a new platform value monitoring.rootEnabled (default true, preserving the historical always-create behaviour). monitoring.rootEnabled is the single render-time source of truth: changing it re-renders cozystack-basics (helm-controller watches the cozystack-values Secret it flows into). A live `lookup` of Tenant/root spec.monitoring is deliberately NOT used: cozystack-basics is an operator-generated HelmRelease with drift detection off, so it re-renders only on install/upgrade/values-change — never on a reconcile tick or when a lookup result changes — and a lookup would go stale in both directions. Operators must keep monitoring.rootEnabled in sync with Tenant/root spec.monitoring. Covered by helm-unittest across all four charts: readiness gate fields, empty-vs-populated logsStorages contract, ExternalName present/absent and null-guard contract, and the platform wiring into the cozystack-values Secret. The CEL health predicates are exercised live, not in helm-unittest (which cannot evaluate CEL). Adds the missing `test:` target to packages/extra/monitoring/Makefile so its suite runs in CI. Known limitation (follow-up): the legacy cozystack.monitoring PackageSource that installs system/monitoring directly into cozy-monitoring cannot carry the readiness gate, because the engine's ComponentInstall/HelmRelease builder and the vendored helm-controller API v1.4.3 lack waitStrategy/healthCheckExprs. That source is not referenced by any active bundle; full coverage needs a helm-controller bump plus engine support. Signed-off-by: Alexey Artamonov <aleksei.artamonov@aenix.io>
