Aggregate counts, top word frequency, readability, and warnings in one payload.

Return deterministic structural counts: characters, words, sentences, paragraphs, headings, bullets, and averages.

Return rough English readability estimates with caveats for short, bullet-heavy, heading-heavy, or mixed-language text.

Return caveats explaining when counts, frequency, or readability may be misleading.

Return normalized top-N token frequency with optional stopword filtering.

Return postcode-level schedule-option distributions and ambiguity percentages for council-native address candidates. This is a triage endpoint, not address proof and not an exact property lookup.
