# logger

Scoped logger built on [`@hyperfrontend/logging`](https://www.hyperfrontend.dev/docs/libraries/logging.md) with namespace prefixes, automatic secret sanitization, and a global log level registry.

`createScopedLogger(namespace, options?)` returns a frozen logger whose output is prefixed with `[namespace]` and whose metadata objects are recursively scrubbed for sensitive keys (matching patterns like `'token'`, `'key'`, `'password'`, `'secret'`, `'credential'`, `'auth'`, `'bearer'`, `'api_key'`, `'private'`, `'passphrase'`). All loggers register themselves so [`setGlobalLogLevel`](https://www.hyperfrontend.dev/docs/libraries/project-scope/core/logger/#api-setGlobalLogLevel) can flip verbosity across the entire library at once. A default [`logger`](https://www.hyperfrontend.dev/docs/libraries/project-scope/core/logger/#api-logger) instance scoped to `project-scope` is exported for general use.
