In 2.0.1 the bridge emits only REQUIRED (iOS only) and REGEX_ERROR (both platforms).
TODO-SDK-FUTURE-SUPPORT: Password-policy cases (INVALID_LENGTH, UNIQUE_CHARACTER,
MAX_REPEAT, MIN_CHARACTERS) exist in both the iOS and Android SDKs but their
policy-validation blocks are behind // TODO markers in PasswordCollector.validate()
(iOS PasswordCollector.swift:49-81, Android PasswordCollector.kt:63-91) and are
never emitted at runtime — add them when both SDKs remove those blocks.
Collector-level validation error returned by the native SDK's
validate()method.
