+# `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.
