nx_analyze.nx

nx_analyze.nx -- THE ANALYST FRONT DOOR. Everything else in this arc is a library with no runnable main: an agent could run the gates but could not actually analyse a dataset over MCP. This is the one registered, cap-gated, verb-driven CLI that makes the whole stack callable -- by a human, an agent, or a workflow step -- and it answers in STRUCTURED JSON so the caller parses fields, not prose. DESIGN, against the operator's checklist: MCP / API : one organ, one tool_allowlist row, driven entirely through the sovereign mgmt API. AGENTIC : output is a single JSON object; every honesty flag (significant, family_significant, truncated, degenerate, survives) is a machine field a planner can branch on. WORKFLOW : verbs are orthogonal primitives -- `sig`/`ci` are pure and cheap for fan-out, `report` is the composed pipeline. A workflow calls exactly the piece it needs. COMPOSED : it owns no statistics of its own; it wires nx_dataframe -> nx_analyst_multi -> nx_analyst_infer (significance / Bonferroni / CI / partial) over nx_analyst_store's sharded loader. One seam, the pieces stay single-responsibility. SCALE : reads REAL seg_store data across key shards <keybase>:0/:1/... past the 256 version window, and DECLARES loaded-row count + truncation in the envelope rather than quietly analysing a slice.
