 ### Vocabulary (`nameparser/vocab/`) and the configuration layer (`nameparser/config/`)
 
-**The default vocabulary is written per word, in TOML, and compiled.** `nameparser/vocab/<tag>.toml` holds one file per BCP 47 language tag, each `[[word]]` entry a `text` and its readings keyed by kind. What a file means, how an entry is built, the kinds and properties with the set each compiles into, exclusions, bearer counts and the steps for adding a word are in `nameparser/vocab/README.md`, the reference for anyone editing the TOML; `tests/v2/test_vocab.py` holds its kind, property, derived-marker and reserved-name tables to the names `build.py` accepts and the sets it compiles, so read it rather than restating it here. The parser never reads the TOML: `tools/vocab/build.py` runs the build checks that replaced the modules' import-time asserts (its docstring numbers them), turns every reading into an index row with its file's tag, and writes the rows as the committed reading index `nameparser/config/_index.py` (#753, phase 3a) and, compiled, as the committed `nameparser/config/_compiled.py`, frozenset literals one entry per line; the build never reads `_index.py` back. A file a shipped pack reads may also hold a `[rules]` table, each key a `Policy` field (`patronymic_rules`, `name_order`, `two_family_names`, `two_given_names`), which the build checks against its `RULE_KEYS` and `PACK_RULES` and writes as `nameparser/config/_rules.py`; `_locale.rules_patch(tag)` turns a file's table into the `PolicyPatch` a pack carries, RU's and TR_AZ's from `ru.toml` and `tr.toml`, and the `two_family_names` of ES, CS and SK from `es.toml`, `cs.toml` and `sk.toml` (#754, 4f; decisions/vocabulary-model's 2026-10-29 4f entry). The compiler is `nameparser/_reading_index.py`'s `compile_readings`, with the kind and property tables it reads (`CATEGORY`, `BEHAVIORAL`, `GATED_WORDS`), so the build and a choice of languages compile alike: `Locale.languages` (3.0, phase 3b) is a choice of BCP 47 tags, which `parser_for` unions across its packs and applies as a delta against the default's compile, `choose` there selecting the readings (a chosen file's `default = false` ones on; on a word a chosen file holds a vocabulary reading of, other files' vocabulary readings off, save `mul.toml`'s and `und.toml`'s; a chosen conjunction's `may_be_initial` dropped), and `changed_words` deriving a choice's deviation surface, which tests/v2/test_locales.py's gate reads (decisions/vocabulary-model, 2026-10-29 3b); the build keeps the checks and loads that module by path, as it loads `_lexicon.py`, and `tests/v2/test_reading_index.py` holds that the index compiled with no choice is `_compiled.py` exactly. `readings_of(text)` there is the run-time reader of the index, every reading of a word with its file's tag, loaded on first call; `languages_of(text, categories)` is the reader a parse calls, from assemble, for `Reading.languages` (3.0), so the first parse that reads a word from its `Lexicon`'s vocabulary loads the index. Each `config/` module re-exports its constants from `_compiled.py` (`TITLES = _compiled.TITLES`) under its autodoc docstring, so the public names and the docs did not move. `tests/v2/test_vocab.py` fails when `_compiled.py` is stale, and `tests/v2/test_reading_index.py` when the index is, each naming the refresh command, and `test_vocab.py` gives every build check a mutation. The model, the phasing and what was declined: decisions/vocabulary-model.

 The `config/` SETS are frozen since 2.2 (#293): there is no `.add()`/`.remove()` on any of them, so a default word list is changed at runtime by configuring a `Lexicon`, never by editing the constant, and the shipped default is changed by editing the TOML and rebuilding. **Neither dict was frozen, and `CAPITALIZATION_EXCEPTIONS` is not covered by anything else either.** `REGEXES` is a compiled-pattern table rather than vocabulary and was never in #293's scope; `CAPITALIZATION_EXCEPTIONS` is vocabulary-shaped and is a decided, in-scope exemption. So the hazard the freeze closes is still live for it: `CAPITALIZATION_EXCEPTIONS['dclinpsy'] = 'DClinPsy'` after the first parse misses the cached `Lexicon.default()`. Same advice — configure the object (`dataclasses.replace(lexicon, capitalization_exceptions=...)`). `tests/v2/test_contracts.py::test_every_vocabulary_constant_is_frozen` names both dicts as explicit exemptions rather than letting its `isinstance` filter drop them.
