"""
Tests that internal exception text is never leaked to API clients in
api/routers/sources.py and api/podcast_service.py.

These previously interpolated the raw exception (`detail=f"...: {str(e)}"`)
into the client-facing error response - inconsistent with the safer pattern
already used elsewhere in the same files (e.g. the download handlers),
which log the raw exception server-side but return a fixed generic
message. Every occurrence already had a matching logger.error() call, so
this was a client-facing message change only, not a logging change.
