+## 2026-06-10 P4 — custom-test ergonomics (branch 29a28e2)
+
+Pre-change sweeps confirmed the plan's zero-users claims: no top-level non-lifecycle test_*.py in
+any recipe dir; no recipe test file reads os.environ / CCCI_OP_STATE_FILE directly (the only
+op-state consumers are the generic assertions via harness.generic.op_state — harness-side, fine).
+So P4 = discovery glob removal + new op_state fixture + pinning tests; no test migrations needed.
+test_discovery.py's HC2 gate test moved its repo-local custom fixture under functional/ (the rule);
+test_discovery_phase2.py now asserts top-level custom is NOT discovered. op_state fixture skips
+(clear reason) when env unset / file missing / unparseable; tested via request.getfixturevalue.
+
+Verified on cc-ci: cc-ci-run -m pytest tests/unit -q -> 184 passed; lint PASS.
+
+Next: P5 — customization manifest (print block + results.json key).
