func PrincipalExtractionHandler ¶

func PrincipalExtractionHandler(principalExtractor auth.PrincipalExtractor) func(next http.Handler) http.Handler

PrincipalExtractionHandler returns middleware that extracts principal context, enriches request logs with principal fields (principal, auth_source), and stores the principal in the request context.

The middleware uses the request-scoped zerolog context logger for all log output, so log entries from this middleware automatically carry request_id and other fields injected by upstream middleware (e.g. requestIDMiddleware).
