Returns the closed grammar registry: feature ids, types, ranges, operators, windows, sequence rules, limits, and error codes.
Returns the research universe and coverage. The default is a compact summary; use `symbols: [...]` for selected full records or `full: true` for the verbatim canonical universe.
Turns prose into a proposed query document. It does not execute the query. Optional `time_zone` accepts an IANA time zone for calendar planning.
Executes a `research_query.v2` document and returns canonical result bytes with counts, denominators, outcomes, the unconditional same-scope reference, and the reproducibility key.
Continues a prior scan with its opaque cursor. Never construct cursors manually.
Reads registry feature values, window aggregates, and fired rules as of a recorded moment.
Counts matches and eligible buckets for one clause over a window.
Finds the deterministic intersection across multiple moments with selection-bias caveats included.
Retrieves a published report by its 8-character canonical hash.
Compares what followed every match with what followed every other eligible predicate-false bucket.
Partitions one matched population at its existing anchors into split-true, split-false, and split-absent outcome summaries.
