Issues

• Terminal sandbox lifecycle events (killed) silently dropped under burst: non-blocking ClickHouse queue, no retry, no back-pressure

• api: autoPause default is declared in the spec and in a Go constant with no test keeping them in sync

• extra-compatible-node-models is unusable without LaunchDarkly: self-hosted heterogeneous-CPU clusters can't enable cross-CPU placement

• Raise sandboxes-per-node by shrinking per-sandbox memory cost: live balloon reclaim, cross-sandbox same-template page sharing, pool-pressure auto-pause

• proxy: no request-outcome metric to distinguish routing (500) / upstream (502) / client-closed (499) failures
