"""Unit tests for the L5 lint executor (harness.lint) — phase lvl5.
Covers the table parser + classifier against real abra-0.13 output shapes (probed on the CI
host 2026-06-11, JOURNAL-lvl5), and run_lint's never-raise / never-silent-pass guarantees via
a fake-PATH `script` shim (no real abra needed). Run cold:
cc-ci-run -m pytest tests/unit/test_lint.py -q
