+"""Tests for agent/tts_registry.py and agent/tts_provider.py.
+
+Covers:
+- Registration happy path
+- Registration rejection: non-TTSProvider type
+- Registration rejection: empty/whitespace name
+- Built-in name shadowing: warning + silent ignore (no exception)
+- Re-registration: overwrites + logs at debug
+- Case + whitespace insensitivity on lookup
+- ABC contract: default implementations work
+- ABC contract: synthesize() must be implemented
+- ABC contract: stream() raises NotImplementedError by default
+- resolve_output_format helper coerces invalid input
