"""Tests for docker-compose.yml port exposure.
Covers issue #50 acceptance criteria:
- ``docker-compose.yml`` exposes port 4096 on ``0.0.0.0`` (open to the network)
so that NPM (Nginx Proxy Manager) on a separate host can reach the opencode
web UI via ``193.3.168.35:4096``.
- The previous ``127.0.0.1:4096:4096`` binding (localhost-only) is gone — it
blocked cross-host NPM proxying.
PyYAML is not a direct project dependency, so the compose file is parsed
manually by tracking indentation of the ``ports:`` block (mirrors the
frontmatter parser in ``test_agent_frontmatter.py``). A raw-text assertion
is also included as a belt-and-suspenders check.
