# Results dashboard (§4.5, D7): the YunoHost-CI-like overview at ci.commoninternet.net. Reads the
|
|
# Drone API (read-only) and renders latest-run-per-recipe + SVG badges. Packaged as a Nix-built OCI
|
|
# image and run as a swarm service on `proxy`, routed by traefik at Host(ci.commoninternet.net) — the
|
|
# comment-bridge's Host && PathPrefix(`/hook`) rule is longer, so /hook still wins (priority by rule
|
|
# length). Deployed by an idempotent-reconcile oneshot (same pattern as bridge/drone).
