- TokenRedactorTest (7 unit tests): all four regex patterns, multiple
secrets in one body, null input, and the no-op pass-through case.
Guards against silent regression of the redaction regexes (which
previously drifted across three duplicated copies).
- ConnectionVerifierTest: HTTP 429 during refresh raises
PlatformUnavailableException, not TokenExpiredException. Locks in
the rate-limit-as-transient behavior added when consolidating the
refresh logic.
