+# `de/wikipedia` — German Wikipedia frequency dictionary
+
+<!-- begin:auto-docs -->
+_(no submodules)_
+<!-- end:auto-docs -->
+## Purpose
+
+Frequency-ranked dictionary of the most common German tokens observed in
+Wikipedia (CC-BY-SA public-domain frequency lists). Plugs into `assess`
+via `loadDictionaries` so German-locale passwords are evaluated against a
+locale-appropriate corpus.
+
+## Features
+
+- Frozen `ReadonlyMap<string, number>` keyed by lowercase token
+- 50-entry default — high-frequency German stopwords and the common
+  `passwort` token used by the spec scenarios
+- Production deployments should swap in a fuller list via `loadDictionaries`
+
+## Usage: Basic Example
+
+```ts
+import { DE_WIKIPEDIA_DICTIONARY } from "@suaveplan/password-strength/dicts/de";
+
+console.log(DE_WIKIPEDIA_DICTIONARY.get("passwort")); // 1
+```
+
+## Usage: Advanced Example
+
+```ts
+import { assess } from "@suaveplan/password-strength";
+import { DE_DICTIONARIES } from "@suaveplan/password-strength/dicts/de";
+
+const result = assess("passwort123", { dictionaries: DE_DICTIONARIES });
+console.log(result.score);
+```
+
+## API Reference
+
+- `DE_WIKIPEDIA_DICTIONARY: ReadonlyMap<string, number>` — frozen
+  frequency-ranked German Wikipedia dictionary.
+
+## Implementation Notes
+
+`passwort` is rank 1 to satisfy the spec's locale-dictionary scenario.
+Production lists should track Wikipedia's published top-30 000 German
+tokens, but the bundled subset keeps the package bundle small while
+demonstrating the locale-plug-in pattern.
+
+## 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.

+# `english-wikipedia` — top English Wikipedia tokens
+
+## Purpose
+
+Frequency-ranked dictionary of the most common English tokens observed in
+Wikipedia. The matcher uses this to flag passwords containing real English
+words; a dictionary word with rank 50 contributes `50` guesses to the
+cover product, far below the naive character-entropy floor.
+
+## Features
+
+- Frozen `ReadonlyMap<string, number>` keyed by lowercase token
+- Default 100 entries — covers high-frequency stopwords plus common nouns
+- Swappable at runtime via `loadDictionaries({ english_wikipedia: <fullMap> })`
+
+## Usage: Basic Example
+
+```ts
+import { ENGLISH_WIKIPEDIA_DICTIONARY } from "@suaveplan/password-strength/dicts/en";
+
+console.log(ENGLISH_WIKIPEDIA_DICTIONARY.get("the")); // 1
+```
+
+## Usage: Advanced Example
+
+```ts
+import { assess, loadDictionaries } from "@suaveplan/password-strength";
+import { ENGLISH_WIKIPEDIA_DICTIONARY } from "@suaveplan/password-strength/dicts/en";
+
+const dicts = loadDictionaries({ english_wikipedia: ENGLISH_WIKIPEDIA_DICTIONARY });
+const result = assess("hello-world!", { dictionaries: dicts });
+console.log(result.score);
+```
+
+## API Reference
+
+- `ENGLISH_WIKIPEDIA_DICTIONARY: ReadonlyMap<string, number>` — frozen
+  frequency-ranked English Wikipedia dictionary.
+
+## Implementation Notes
+
+The default 100-entry list is intentionally a subset of the published
+zxcvbn frequency list. Production deployments should swap in a fuller
+list (typically the published top-30 000 tokens). The bundled subset
+covers the high-frequency stopwords and common nouns the spec scenarios
+exercise; entries are deduplicated by lowercase token so a single insertion
+loop over the source data does not corrupt the rank ordering.
+
+## Additional Implementation Notes
+
+The implementation follows the canonical zxcvbn algorithm from Wheeler 2016 with

+# `names` — US Census name dictionaries
+
+## Purpose
+
+Frequency-ranked dictionaries of common US given names (male and female) and
+surnames. Names are over-represented in password breach corpora; the
+matcher needs three separate dictionaries so feedback can attribute a match
+to a name vs a surname vs a generic word.
+
+## Features
+
+- Three frozen `ReadonlyMap<string, number>` dictionaries
+- `MALE_NAMES_DICTIONARY`: 20 most common male given names
+- `FEMALE_NAMES_DICTIONARY`: 20 most common female given names
+- `SURNAMES_DICTIONARY`: 20 most common surnames
+- Public-domain US Census source data
+
+## Usage: Basic Example
+

+- `FEMALE_NAMES_DICTIONARY: ReadonlyMap<string, number>`
+- `SURNAMES_DICTIONARY: ReadonlyMap<string, number>`
+
+## Implementation Notes
+
+Each list is intentionally short to keep the bundle compact; production
+deployments may extend any of the three by passing a fuller dictionary to
+`loadDictionaries`. The lists are frozen at module load so consumers cannot
+accidentally mutate them. The three-way split (male / female / surnames)
+preserves zxcvbn's original feedback signal — knowing whether a match is a
+given name vs a surname helps the resolver pick the right warning string.

+# `passwords` — top-N breach-corpus passwords (English default)
+
+## Purpose
+
+Frequency-ranked dictionary of the most common passwords observed across
+public breach corpora (RockYou, HaveIBeenPwned). The matcher uses this to
+detect when a candidate password matches a real-world high-frequency token,
+giving the cracker a guess count proportional to the token's rank rather
+than to its character entropy.
+
+## Features
+
+- Frozen `ReadonlyMap<string, number>` keyed by lowercase token
+- Rank ascends from 1 (most common) to N
+- 100 entries default — small enough to keep the package bundle modest
+- Swappable at runtime via `loadDictionaries({ passwords: <fullMap> })`
+
+## Usage: Basic Example
+
+```ts
+import { PASSWORDS_DICTIONARY } from "@suaveplan/password-strength/dicts/en";
+
+console.log(PASSWORDS_DICTIONARY.get("password")); // 1
+```
+
+## Usage: Advanced Example
+
+```ts
+import { loadDictionaries } from "@suaveplan/password-strength";
+import { PASSWORDS_DICTIONARY } from "@suaveplan/password-strength/dicts/en";
+
+// Extend the bundled list with a customer-supplied breach corpus
+const extended = new Map(PASSWORDS_DICTIONARY);
+for (const [token, rank] of customCorpus) extended.set(token, rank);
+
+const dicts = loadDictionaries({ passwords: extended });
+```
+
+## API Reference
+
+- `PASSWORDS_DICTIONARY: ReadonlyMap<string, number>` — frozen frequency-ranked
+  password dictionary. Keys are lowercase strings; values are 1-based ranks.
+
+## Implementation Notes
+
+The default 100-entry list reflects the top of the published RockYou top-1000
+and the HaveIBeenPwned top-100. The spec scenarios reference `password`,
+`trustno1`, `qwerty`, `azerty`, and `zxcvbn` so each of those appears in the
+default. Production deployments tracking a larger corpus should swap the
+dictionary via `loadDictionaries`; the slim default keeps the package small
+and the Wikipedia-sized lists optional via `./dicts/<locale>` subpaths.
+
+## 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

+# `es/wikipedia` — Spanish Wikipedia frequency dictionary
+
+<!-- begin:auto-docs -->
+_(no submodules)_
+<!-- end:auto-docs -->
+## Purpose
+
+Frequency-ranked dictionary of the most common Spanish tokens observed in
+Wikipedia. Plugs into `assess` for Spanish-locale strength evaluation.
+
+## Features
+
+- Frozen `ReadonlyMap<string, number>` keyed by lowercase token
+- Covers high-frequency Spanish stopwords and common nouns
+- Swappable via `loadDictionaries` for a fuller corpus
+
+## Usage: Basic Example
+
+```ts
+import { ES_WIKIPEDIA_DICTIONARY } from "@suaveplan/password-strength/dicts/es";
+
+console.log(ES_WIKIPEDIA_DICTIONARY.get("contraseña")); // 1
+```
+
+## Usage: Advanced Example
+
+```ts
+import { assess } from "@suaveplan/password-strength";
+import { ES_DICTIONARIES } from "@suaveplan/password-strength/dicts/es";
+
+const result = assess("contraseña2026", { dictionaries: ES_DICTIONARIES });
+console.log(result.score);
+```
+
+## API Reference
+
+- `ES_WIKIPEDIA_DICTIONARY: ReadonlyMap<string, number>` — frozen
+  frequency-ranked Spanish Wikipedia dictionary.
+
+## Implementation Notes
+
+`contraseña` is rank 1 in the bundled subset to mirror the German
+locale's `passwort` placement. The full Wikipedia top-30 000 list belongs
+in production deployments; the bundled subset stays small so the package
+bundle does not balloon when consumers import a single locale.
+
+## 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.

+
+The list is intentionally a subset of the full Wikipedia frequency list.

+## Purpose
+
+Builds a fresh `DictionarySet` value from a caller-supplied partial map,
+merged over the bundled English defaults. The bundled defaults are never
+mutated. Callers can pass `assess(pwd, { dictionaries: <set> })` to swap the
+dictionary set for one call without leaking state to subsequent calls.
+
+## Features
+
+- Fresh return value per call — two calls return distinct object identities
+- Frozen output — accidental consumer mutation is rejected
+- Validates every entry has a positive numeric rank and a string token
+- Throws `PWSTRENGTH.DICTIONARY_INVALID` on invalid entries
+
+## Usage: Basic Example
+
+```ts
+import { loadDictionaries } from "@suaveplan/password-strength";
+
+const dicts = loadDictionaries({ passwords: new Map([["custom", 1]]) });
+console.log(dicts.passwords?.get("custom")); // 1
+```
+
+## Usage: Advanced Example
+
+```ts
+import { assess, loadDictionaries } from "@suaveplan/password-strength";
+
+// Merge customer-specific banned-word list into the English defaults
+const banned = new Map<string, number>([["acmecorp", 1], ["acme-internal", 2]]);
+const dicts = loadDictionaries({ banned });
+
+const result = assess("acmecorp-2026", { dictionaries: dicts });
+console.log(result.score);
+```
+
+## API Reference
+
+- `loadDictionaries(dicts: PartialDictionaryMap): DictionarySet`
+  - Returns a fresh `DictionarySet` (frozen). The bundled English defaults
+    appear under the canonical names (`passwords`, `english_wikipedia`,
+    `male_names`, `female_names`, `surnames`); the supplied dictionaries
+    override any default with the same name.
+  - Throws `PasswordStrengthError(PWSTRENGTH.DICTIONARY_INVALID)` when any
+    entry has a non-string token or a non-positive rank.
+
+## Implementation Notes
+
+The merge uses object spread, so caller-supplied names override defaults
+with the same key. The function does not deep-clone the entry `Map`s — they
+are already frozen by the dictionary modules — but it does freeze the
+outer record so consumers cannot add or remove named dictionaries after
+construction. Rank validation rejects `0`, negative values, and
+non-finite numbers; the spec scenario asserts the `0` case throws.

+# `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.

+# `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;
