# `zh-Hans/wikipedia` — Simplified Chinese frequency dictionary

<!-- begin:auto-docs -->
_(no submodules)_
<!-- end:auto-docs -->
## Purpose

Frequency-ranked dictionary of the most common Simplified Chinese tokens
observed in Wikipedia. Plugs into `assess` for Simplified Chinese-locale
strength evaluation. Tokens are short surface forms (single CJK ideogram
or short word) so the matcher can recognise common prefixes in mixed
input.

## Features

- Frozen `ReadonlyMap<string, number>` keyed by surface-form token
- Covers high-frequency CJK ideograms including `密码` (password)
- Swappable via `loadDictionaries`

## Usage: Basic Example

```ts
import { ZH_HANS_WIKIPEDIA_DICTIONARY } from "@suaveplan/password-strength/dicts/zh-Hans";

console.log(ZH_HANS_WIKIPEDIA_DICTIONARY.get("密码")); // 1
```

## Usage: Advanced Example

```ts
import { assess } from "@suaveplan/password-strength";
import { ZH_HANS_DICTIONARIES } from "@suaveplan/password-strength/dicts/zh-Hans";

const result = assess("密码123", { dictionaries: ZH_HANS_DICTIONARIES });
console.log(result.score);
```

## API Reference

- `ZH_HANS_WIKIPEDIA_DICTIONARY: ReadonlyMap<string, number>` — frozen
  frequency-ranked Simplified Chinese Wikipedia dictionary.

## Implementation Notes

The default subset is intentionally small; CJK tokens are surface forms
rather than word segments, so a richer production list typically uses
segmenter-aware frequencies. The matcher's `String.prototype.slice`
operates on UTF-16 code units, which means multi-code-unit CJK characters
are matched character-by-character as their canonical surface form.

## 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.
