Delete the residual internal/alerts/alerts.go catch-all and move its remaining ownership groups into config_facade, model, constants, metric_hooks, manager, default_config, lifecycle, and escalation files.
Keep compatibility aliases in the alerts package, preserve the type-alias identity test, add a default-config pointer isolation regression test, and record the new ownership split in the alerts subsystem contract.

Move active alert save/load, secure storage handling, startup restore migration, periodic persistence, and stale tracking cleanup into dedicated alerts package owners.

Move guest metric projection, per-disk guest metric evaluation, powered-off lifecycle alerts, Pulse tag controls, relaxed thresholds, and guest suppression cleanup into internal/alerts/guest.go.
Record guest.go as the Proxmox guest alert owner in the alerts subsystem contract and add a Pulse-tag characterization test.
Proof: go test ./internal/alerts/...
Move storage-health reason normalization, ZFS assessment helpers, active health alert value lookup, and canonical health-assessment alert synchronization into internal/alerts/health_assessment.go.
Record health_assessment.go as the shared storage-health assessment owner in the alerts subsystem contract and add a reason-code characterization test.
Proof: go test ./internal/alerts/...
Move threshold lookup, per-metric delay resolution, legacy metric alert lifecycle, metric options, and shared metric key helpers into internal/alerts/metric_runtime.go.
Record metric_runtime.go as the shared metric-threshold runtime owner in the alerts subsystem contract and add a metric-options characterization test.
Proof: go test ./internal/alerts/...
Move Proxmox disk canonical identity, disk health assessment, known-firmware suppression, and SSD wearout alerting into internal/alerts/disk_health.go.
Keep the Manager API unchanged while recording disk_health.go as the Proxmox disk-health checker owner in the alerts subsystem contract.
Proof: go test ./internal/alerts/...
Move snapshot age and size evaluation, backup rollup age evaluation, inventory readiness, namespace disambiguation, template matching, and backup/snapshot cleanup into internal/alerts/backup_snapshot.go.
Keep the generic async active-alert save helper in the central package because canonical metric migration still shares it, and record backup_snapshot.go as the backup/snapshot owner in the alerts subsystem contract.
Proof: go test ./internal/alerts/...
Move host-agent identity, metric projection, disk/SMART/RAID/Unraid health handling, cleanup, and offline lifecycle into internal/alerts/host.go.
Keep shared health-assessment evaluation package-level for now because storage ZFS and host SMART/RAID still share that bridge, while recording host.go as the host checker owner in the alerts subsystem contract.
Proof: go test ./internal/alerts/...
Move Proxmox node metric, temperature, offline lifecycle, host-agent deduplication, and node display-name cache support into internal/alerts/node.go.
Keep the Manager API unchanged while recording the node checker owner in the alerts subsystem contract and adding a focused display-name cache key characterization.
Proof: go test ./internal/alerts/...
Move PBS connectivity and metric evaluation into internal/alerts/pbs.go, and move storage connectivity, usage, and ZFS health evaluation into internal/alerts/storage.go.
Keep the Manager API unchanged while recording PBS and storage as resource-checker owners in the alerts subsystem contract, with focused characterization tests for PBS offline normalization and ZFS device labels.
Proof: go test ./internal/alerts/...
Move Docker host connectivity, container state and health, metric projection, service gap/update-state checks, image update timing, and Docker tracking cleanup into internal/alerts/docker.go.

Proof: go test ./internal/monitoring
Move active-alert projection, sorting, metadata coercion, recently resolved reads, history wrappers, and notify-existing redispatch into internal/alerts/read_model.go.

Move alert dispatch, flapping suppression, quiet-hours suppression, monitor-only suppression, cooldown, and rate-limit policy into internal/alerts/notification_policy.go.
Keep Manager behavior and public API unchanged while recording the new alerts contract owner and adding monitor-only dispatch proof.
Proof: go test ./internal/alerts/...; go test -json ./internal/api -count=1; go test ./internal/api ./internal/monitoring ./internal/ai/... ./internal/websocket (internal/api did not reproduce on isolated rerun; other packages passed in the broad run).
Extract alert config types, normalization, and identity helpers into internal/alerts/config while preserving the existing alerts package API through aliases and wrappers.
Move Manager callback lifecycle state into a same-package callbackBus, keeping public Set/Subscribe methods unchanged.
Harden metrics SQLite artifacts to owner-only permissions and cover permissive umask behavior.

The four-step coachmark over the top tabs was a tour pretending to be
guidance: each step duplicated the tab title in one sentence, and the
Reopen control on /settings/system-general spawned a centered panel with
no spotlight target because the tabs only exist on dashboard routes.
Delete the modal, the localStorage dismissal key, the reopen event, the
Reopen row in General settings, and the matching guardrails so the
shared-primitives tests stop pinning the deleted owner split. Drop the
WhatsNew dismissal helpers and addInitScript bypasses from the
integration suite, and the dedicated tour test in
19-telemetry-disclosure.
