Observability Agent

Install and configure a host-native metrics + logs agent on a remote Debian/Ubuntu host over SSH, for a VictoriaMetrics (pull) + VictoriaLogs (push via Vector) backend.

Model:

• @magistr/observability/agent — drives one target host over SSH. Methods:
  • install — apt-installs prometheus-node-exporter + prometheus-blackbox-exporter and installs vector from the pinned .deb (idempotent).
  • configure — writes exporter defaults (bound to bindAddress — set it to a WireGuard tunnel IP to keep exporters off the public interface), a blackbox module set (http_2xx / http_public / icmp), grants blackbox CAP_NET_RAW for ICMP probes, and configures Vector to tail nginx + syslog and ship to VictoriaLogs' Elasticsearch-bulk endpoint. Adds the vector user to adm so it can read the logs.
  • status — systemd state of all three services + whether each exporter is answering on its bound address.

The home VictoriaMetrics scrapes bindAddress:9100 (node) and bindAddress:9115 (blackbox) over the tunnel; Vector pushes logs to VictoriaLogs. Pairs with @magistr/victoriametrics for querying.

Release 2026.07.16.2 — align model versions with manifests

Maintenance release across the @magistr extensions. For most packages this carries no functional change: the only edit is the model's version: field, brought back in line with its manifest version so the published model type version and the package version no longer drift.

Functional changes in this release are limited to:

• anime-cron: normalizeTitle now strips a ": subtitle" suffix and a trailing parenthesized year before comparison, fixing dedup false-misses where the torrent title carries a subtitle or year that the AniList romaji does not.

• arckit: first publish. Standalone ArcKit port — a 12-phase architecture governance state machine with 65 bundled templates, driven by a bundled skill.

Also tracks three extensions (kaiten, observability-agent, music-library) that previously existed only as untracked working-tree directories, recovered from stashes.
