September 2026

Product notes for September 2026. Previous: August 2026. Index: What’s new.

Week of September 28

• Offline evaluation covers more artifact shapes. Besides vectors, clusters, and graphs, pattern: evaluation can score profiles, filter decisions, stability reports, relations, frames, candidates, assertions, constraints, identity/dedup, trust, and competency questions — still a bounded sample, still domain-neutral formulas.
• Frequent patterns without a giant in-RAM mine. Steps count itemsets per shard, merge globally, then expand association rules (support, confidence, lift).
• Hierarchy checks as a kernel. Acyclic parent maps, multi-parent, disjoint-root overlap — data in, report out; the step still owns catalog policy.

Details: evaluation, algorithm catalog.

Week of September 19

• Launch forms stay short. Fields and control groups can be hidden (defaults still apply) or advanced (expander). Flush can sit in the IO expander (attach_to_io).
• Local Ray does not talk to Kubernetes. DRTOLLER_LOCAL_RAY=1 skips KubeRay shape patch, live LB resolve, and post-inflate hooks. Streamlit hides pod/node knobs (parallelism_controls.profile: local or auto from that env).

Details: Streamlit forms, Ray, CLI operations.
