Module auth 

Shared authentication logic for all protocol adapters.

This module is the single source of truth for API key validation and permission checking. Every adapter (HTTP, WebSocket, gRPC, MCP) must use these functions instead of rolling their own validation.

Enums

AuthResult

Result of an authentication check.

Functions

check_auth

Validate an API key against the configured keys with permission checking.

extract_bearer_from_value

Extract a bearer token from an “Authorization” header value string.

find_key_ct

Constant-time find over an api-key list (Issue 62).
