Build a hierarchical multidimensional grid (axes -> sub-lenses) adapted to the subject's context. Returns the grid to fill, not the analysis.

List every known context with its axes and sub-lenses.

Deterministic, STATELESS check of a filled analysis against its v2 frame (multidim_analyze format v2). Returns an ACCEPT / WARNING / REJECT verdict per section with actionable error codes. Never modifies the store, calls no LLM, never judges the truth of the content: structure, internal consistency and checkable requirements only. The calling LLM redoes ONLY the rejected sections, within the frame's max_validation_rounds (tracked by the caller).

Create or enrich a context. Use only to promote a lens reusable beyond the current subject: deliberate promotion, never automatic. Persists to the dedicated store (the only write door).
