I've diagnosed and fixed the issue. The complete solution is written to /workspace/solution.md (patch at /workspace/auger-legacy-domain-fix.patch). Here it is:

Fix: answer --domain canonical validation vs. legacy 9.01/9.02 fixtures

Repo: coding-hermes/auger · Commit: 542212347cadf3211a4f5b9eee9b488bb48e2293 (AUG-038) Files changed: tests/test_auger.py only (no auger.py change needed) Baseline: py_compile PASS, ruff PASS, focused domain/status tests 8 passed, full suite 220 passed / 16 failed / 1 skipped.

Root cause

AUG-038 added resolve_answer_domain(raw) and wired it into cmd_answer so --domain is checked against the one canonical grid (4.01–4.44) and refused before any write. The implementation is correct. The test suite still contains pre-grid fixtures whose shared helpers hard-code legacy numbers:

Location Fixture Old → New Write path
test_auger.py:1161 bundle round-trip test 9.01 → 4.05 CLI answer
test_auger.py:3589 break_cli(...) (3 tests) 9.02 → 4.06 CLI answer
test_auger.py:5179 sibling_decision(...) (3 tests) 9.01 → 4.05 insert_decision
test_auger.py:5205 record_decision(...) (17 tests) 9.01 → 4.05 CLI answer

Every record_decision/break_cli caller begins with assert rc == 0, so the new SystemExit("refused: unknown domain '9.01' …") surfaces as a fixture-setup failure — the 16-test cluster.

Fix

Migrate the fixtures onto the canonical grid (the legacy numbers were arbitrary fixture data, carry no assertions, and were never a supported user surface). record_decision and sibling_decision keep a shared value (4.05); break_cli keeps its distinct value (4.06). A compatibility exception that let 9.01/9.02 through answer --domain would re-open the exact bug AUG-038 closes, so it is rejected and guarded by a new test:

def test_legacy_domain_values_are_refused_against_a_readable_canonical_grid(tmp_path, monkeypatch):
    monkeypatch.setenv(auger.DOMAIN_GRID_ENV, str(tmp_path))
    for n in range(1, 45):
        write_grid_file(str(tmp_path), f"4.{n:02d}-stub{n}", GRID_KV_HEADER)
    for legacy in ("9.01", "9.02"):
        with pytest.raises(SystemExit) as ei:
            auger.resolve_answer_domain(legacy)
        assert "unknown domain" in str(ei.value) and legacy in str(ei.value)
    assert auger.resolve_answer_domain("4.05") == ("4.05", "stub5")
    assert auger.resolve_answer_domain("4.06") == ("4.06", "stub6")

The full unified diff (4 one-line migrations + guard test) is in the patch file and in §3 of solution.md.

Verification

Check Result
python3 -m py_compile auger.py tests/test_auger.py PASS
ruff check auger.py tests/test_auger.py All checks passed!
New guard test 1 passed
grep -n "9\.0[12]" tests/test_auger.py only the guard test's intentional references
Offline suite (live tests self-skip here) 64 passed, 174 skipped, 0 errors
Direct validator (stub grid) 4.05/4.06 accepted; 9.01/9.02 refused with unknown domain … 4.01-4.44

On the full-gate host the expected result is the baseline's 16 failures cleared plus the new test: 237 passed, 0 failed, 1 skipped, with tests/gate.sh reaching GATE PASS.

Notes

Existing namespaces holding legacy 9.01/9.02 rows are unaffected — the validator gates new writes, not reads. This is the explicit, tested compatibility policy: legacy numbers are not a compatibility surface for user input, and unknown user domains are still refused.
