Independently verified region/feature/source GreatVowelShift chronology, not universal simultaneous date range. Exact independently verified context/edition key, not live or embedded reference data.

}Limitations and assumptions
The language variety, analytical definitions and reference scope are supplied by the caller. No corpus, speech or complete/current linguistic registry is analyzed automatically. Reference records and their claimed verification are supplied by the caller; the tool does not retrieve or verify them.
Missing required fields, unknown fields, wrong types and violated rules return input issues. Numeric values and outputs must be finite. Lists and matrices must be dense, without missing cells. Numeric lists allow at most 10000 entries; ordinary string lists allow at most 128 strings of 128 UTF-16 units each; numeric matrices allow at most 128 rows and 128 columns, subject to narrower requirements above.
