Root cause of the Grafana "readdirent /etc/grafana/dashboards: no such file or
directory": the CI runner checks out into an ephemeral act workspace that is
removed after the job, so binding the compose config files straight from it
dangles the mounts in the long-lived containers (verified the act source dir is
emptied after the job). caddy/otelcol/prometheus/tempo read their config once at
startup so they survive, but would break on a restart — same latent bug.
Fix (mirrors ../galaxy-game's $HOME/.galaxy-dev/monitoring): the deploy job seeds
the config dirs to a stable $HOME/.scrabble-deploy and the compose binds them via
${SCRABBLE_CONFIG_DIR:-.} (local runs keep "."). Documented in the compose header,
deploy/README.md and the ci.yaml step.
- deploy/docker-compose.yml: mount the provisioned dashboards at
/etc/grafana/dashboards, not /var/lib/grafana/dashboards — the grafana-data
volume mounts over the latter and shadows the nested bind, so the provider
logged "readdirent /var/lib/grafana/dashboards: no such file or directory".
dashboards.yaml provider path updated to match.
- Connector telemetry stays OTLP. The VPN sidecar's netns reaches the collector's
internal IP fine (connected route, off-tunnel), but the sidecar's DNS hijacks
name resolution: AWG_CONF must NOT carry a DNS= directive, else otelcol won't
resolve ("produced zero addresses"). Without DNS= the netns uses Docker's
resolver (resolves both otelcol and api.telegram.org). Documented in
deploy/README.md (AWG_CONF row + wiring note), ARCHITECTURE §13, compose comment.
