Equality proof for harnessx-removal (task 7, Requirement 3.2), recorded 2026-09-30.

candidate/      `harnessx_removal_equality.py record` from a `git archive` export of b9afb66 (tasks 1-6 landed),
                same venv (freeze sha256 0e5ad419... identical to the baseline's), no API keys, empty config.
suite-map.json  the suite ids deleted (29), renamed (2) and added (83) since the baseline, each deleted or renamed
                id justified by the design's Tests table and commit cbadc38 or b9afb66.
comparison.json `compare ../2026-09-30-harnessx-removal-baseline candidate --suite-map suite-map.json`:
                equal=True differences=0.

Beyond the comparison: every output file (pairs, benchmark, scan, improve) is raw-byte identical to the baseline
(`diff -rq` differs only in suite.json and env.json; determinism.json is baseline-only), and every surviving test id keeps its outcome.

Instrument note: the first record failed the two test_push_hook cases (exit 1, prior-input never written) because
the recording shell's PATH lacked .venv/bin, so the hook's `exec ousast` could not start. Same failure at b9afb66
in the worktree, gone with .venv/bin on PATH (5 passed). The recorded run has .venv/bin on PATH; the baseline
passed these tests, so its PATH had `ousast` too.
