# Lexical source-coverage audit - 20,047-sentence milestone

## Scope and method

Scope is the 13,750 sentences added from the 6,297 baseline: Batches 125-399 inclusive. Every row has valid,
nonempty `words_used` JSON and nonempty evidence. The audit collected 1,412 distinct lower-cased `words_used` labels
and compared them with three independent source surfaces:

1. verified `lexemes.headword` rows;
2. exact dictionary YAML heads; and
3. boundary-aware exact occurrences in Patz `grammar.md`.

Source hashes at audit time:

- dictionary YAML: `b575ab035ecc60f09f7bfc5537116555f3d290869fe75b2edf0fd8db60fe1b37`
- Patz grammar Markdown: `5f21305f1fca9ee2cb64668e18156d1f322e3bd9e59850fda662bf0673714153`

Direct union coverage is 1,354 / 1,412. Exact matching is deliberately conservative: `words_used` sometimes stores a
bound suffix, inflected stem label, derived construction, compound, or elder surface rather than a dictionary
headword. The remaining 58 were therefore inspected against the actual sentence, interlinear analysis, and evidence.

## Result

All 58 residuals are source-anchored morphological or lexical representations; none is an unanalysed content-word
coinage. Combined with 1,354 direct matches, the audit accounts for 1,412 / 1,412 distinct goal-scope `words_used`
labels. This is evidence about the final reviewed corpus, not permission to skip source lookup in future work.
