ServiceRadar v1.4.64

The agent now hands every native add-on a persistent state
directory, so the anomaly detector keeps its baselines across
add-on upgrades and agent restarts instead of cold-starting;
drift findings draw their episode on the chart for real event
rows; and Create alert rule is back on the event details page.

Whats New

1.4.64

• Agent: every native sidecar add-on receives a persistent
  state directory, <runtime root>/addons/<id>/state (mode
  0700, owned by the user the add-on runs as), created before
  each spawn and exported as SERVICERADAR_ADDON_STATE_DIR. It
  sits beside the versions tree, so an artifact upgrade or
  rollback never touches it (PR #431).
• anomaly add-on 0.3.10: the restart checkpoint no longer
  depends on an operator setting checkpoint_path. Resolution
  is explicit checkpoint_path, else checkpoint.json in the
  agent-provided state directory, else off. A missing parent
  directory is created on the first write, which previously
  left an operator-chosen path silently unwritten. Without a
  checkpoint, every restart cold-started the detector and its
  open episodes were stale-closed by core instead of recovered
  (PR #431). A checkpoint path applied to a running add-on by
  a config-only update now takes effect on the open metric
  feed; before, the feed loop kept the settings it had at
  stream open and nothing was written until the next restart
  (PR #433).
• Web: the drift episode band, baseline and sustained-level
  lines added in 1.4.63 now render for real event rows, whose
  verdict payload lives under unmapped.anomaly; the first
  version only matched the projected metadata.anomaly shape
  (PR #429).
• Web: Create alert rule is back on the event details page for
  operators and admins. The modal is pre-filled from the event
  (provider, subject, severity, message conditions, a slugified
  name and device.uid grouping), validates the threshold and
  window, and saves a stateful alert rule before opening the
  Alerts tab (PR #425, fixes #345).

Upgrade Notes

• The state directory is created by the agent in this release;
  add-ons older than 0.3.10 ignore the variable and behave as
  before. The first checkpoint is written after 100 feed
  frames, so the first restart after this upgrade still
  cold-starts once; later restarts re-warm.
• A profile or assignment that sets checkpoint_path
  explicitly keeps that path. Remove it to use the agent
  default.
