+# `ru/wikipedia` — Russian Wikipedia frequency dictionary
+
+<!-- begin:auto-docs -->
+_(no submodules)_
+<!-- end:auto-docs -->
+## Purpose
+
+Frequency-ranked dictionary of the most common Russian tokens observed in
+Wikipedia. Plugs into `assess` for Russian-locale strength evaluation.
+
+## Features
+
+- Frozen `ReadonlyMap<string, number>` keyed by Cyrillic token
+- Covers high-frequency Russian stopwords and common nouns
+- Swappable via `loadDictionaries`
+
+## Usage: Basic Example
+
+```ts
+import { RU_WIKIPEDIA_DICTIONARY } from "@suaveplan/password-strength/dicts/ru";
+
+console.log(RU_WIKIPEDIA_DICTIONARY.get("пароль")); // 1
+```
+
+## Usage: Advanced Example
+
+```ts
+import { assess } from "@suaveplan/password-strength";
+import { RU_DICTIONARIES } from "@suaveplan/password-strength/dicts/ru";
+
+const result = assess("пароль123", { dictionaries: RU_DICTIONARIES });
+console.log(result.score);
+```
+
+## API Reference
+
+- `RU_WIKIPEDIA_DICTIONARY: ReadonlyMap<string, number>` — frozen
+  frequency-ranked Russian Wikipedia dictionary.
+
+## Implementation Notes
+
+The bundled subset is intentionally compact; production deployments should
+swap in a fuller list. Russian tokens are matched against the lowercased
+form of the input, so `assess` will pick up `ПАРОЛЬ` as well via the
+uppercase variation factor in `estimateGuesses`.
+
+## Additional Implementation Notes
+
+The implementation follows the canonical zxcvbn algorithm from Wheeler 2016 with
+the suaveplan-style additions described in the package proposal: structured error
+codes via the `defineCodes` registry, Zod boundaries at every public entry
+point, OTel histograms and counters keyed to low-cardinality attributes, and
+a strict input-length guard at 200 characters. Consumers integrate with their
+existing observability stack by installing a meter provider before importing
+the package, and with their i18n stack via the `MessageResolver` callback type
+declared in `@suaveplan/types`. The bundled data tables are intentionally
+small to keep the package bundle compact; production deployments should swap
+in fuller frequency-ranked tables via `loadDictionaries`. The default English
+dictionary set is a frozen `DictionarySet` that the matcher never mutates;
+caller-supplied dictionaries override defaults by name.
