Maps AtScale semantic-model elements onto BFO 2020 categories; emits a grounding overlay and RDF for reasoning

Durable append-only JSONL journal for MCP investigation sessions — survives server restarts, supports replay

One command to stand up an AI-queryable AtScale semantic-layer POC, built on @atscale/ps-utils

Pure Rust guardrail that rejects MQO queries naming unmapped catalog fields before execution, with repair suggestions

Authorization gate for semantic-layer agents: route to the PII-safe model variant, or deny by default

Offline tool that turns ungroundable NL questions into draft SML YAML constructs via concept-graph inference

Explain why a metric moved: walk the AtScale concept graph for derivation paths whose parts moved the same way

Result-set eval harness: scores an NL agent against an AtScale semantic layer on the rows it returns, not the query

Merge describe_model from many AtScale clusters into one catalog, with provenance and conflict policies

Filter the AtScale MCP trace store for high-quality MQO interactions, exported as OpenAI chat JSONL for fine-tuning

Claude Code skill: drafts and reviews enterprise B2B data-platform PRDs — template, artifact tree, migration contract

Streamlit chat driving Claude over the AtScale semantic layer: plain-English question in, governed chart out, no SQL

Deterministic CLI that proposes bound-ready follow-up MQOs from session + model hierarchy graph — no LLM, no network

Typed TOML/JSON schema for routing across N AtScale clusters: endpoint, auth, backends, priority; parse, validate, query

CLI that diffs two AtScale describe_model catalogs and flags semantic changes (expression, aggregation) vs cosmetic ones

Rust verdict engine: does a converted measure's result match its Power BI reference under DAX semantics, not float equality?

Keeps query result rows out of an LLM's context: stores them, returns an opaque handle. MemStore default, DuckDB opt-in.

Concurrent TCP health probe for a fleet of AtScale clusters; one JSON report, exit code you can gate on

Easy way to import the HoleFoods Sample into InterSystems IRIS using an AtScale Sample Bundle

Append-only JSONL store, one durable record per MQO interaction: bind, grounding, execute, quality signals
