Since the last update, work on Ooloi has moved from invisible metrics to visible structure.

• Server statistics complete – All 57 metrics now implemented and exposed via HTTP with content negotiation. Grafana and Prometheus dashboards confirm stable memory, disciplined threads, and efficient client handling. The figures held steady even under multi-client concurrency. Result: trust in the foundations. See Testing the Foundations.

• Validation milestone – A year of invisible work proved itself in practice. The Grafana charts showed flat memory lines and zero old-gen collections. No drama – just confirmation that the core architecture can carry what comes next. See Milestone.

• The Rendering Pipeline – ADR-0028 is now complete. This is the scariest ADR so far: the multi-core rendering pipeline that ties everything together and decides whether scrolling through Elektra feels like editing a string quartet, or whether the system stalls. Five stages, plugin hooks at every level, parallelism where possible, enforced order where necessary. This is what makes or breaks Ooloi; the entire engine was built to support this pipeline. See The Rendering Pipeline: Ooloi’s Core Architecture, and, of course, ADR 0028.

Where we are
The foundations no longer need proving. They hold. The rendering pipeline design is finished. Implementation is next, and everything visible will depend on it.
