mesh-llm-analytics

Anonymous, opt-out product analytics for mesh-llm. This is the only crate in the workspace that reports anything to a vendor, which is the point: keeping it in one place makes the full reported surface reviewable in one sitting.

Not to be confused with the [telemetry] config section, which exports OTLP metrics to an endpoint the operator chooses and never leaves their network.

Guarantees

  • Closed vocabulary. Event and Properties admit no free-form String. Text enters only through Label::sanitize, whose grammar rejects paths, prose, and anything over-long. A prompt cannot reach the wire through this API even by mistake, and an unrecognized value becomes redacted.
  • No key, no reporting. The project key is compiled in by the release pipeline via MESH_LLM_POSTHOG_KEY. Source and development builds have no compiled-in key and are inert unless that same variable is set at run time, which is the documented self-hosting path.
  • Never load-bearing. Capture is non-blocking and delivery is best effort. No failure here changes a command's behavior, output, or exit code, and shutdown gives up after a short budget rather than holding a command open.
  • Anonymous by construction. The identifier is a random UUID derived from nothing about the machine, and deliberately not the published mesh identity.
  • No location. Every event sets $geoip_disable and a null $ip.

Opt-out precedence

MESH_LLM_ANALYTICS wins over everything (including the CI check, so the path can still be tested deliberately), then DO_NOT_TRACK, then [analytics] enabled in the config, then CI detection. A missing project key disables reporting regardless of all of them.
