# `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.
