"""Unit tests for core/output_publisher.py (D-050). Tests cover: - publish_to_ssm with mocked SSM (moto) — verifies parameters are written with the right name, type=SecureString, Overwrite=True. - format_comment with sample outputs — verifies safe outputs appear in the comment, sensitive outputs show "(published to SSM)", and the SSM path footer is correct. - post_github_comment with mocked urllib — tests the no-op case (no token / no PR number) and the success case. - The CLI __main__ path.
