"""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.
