+### CL-058: TASK22260 next slice — phase6 behavioural harness compatibility parity
+
+date: 2026-03-25
+author: Cline
+scope: `tests/phase6/service-behaviour.test.cjs`
+type: change
+rationale: Keep older phase6 behavioural harness aligned with service client-wrapper migration by adding default helper injections required by `getJson`/`requestJson`-based direct services.
+impact: Restores phase6 behavioural regression execution parity (8/8) with no runtime code changes.
+status: completed
+
+Summary:
+
+- Updated `loadServiceModule` default context in `tests/phase6/service-behaviour.test.cjs`:
+    - added default `getJson(...)` mock backed by `axios.get(...).then(res.data)`
+    - added default `requestJson(...)` mock backed by `axios(config).then(res.data)`
+- Preserved existing test assertions and behavior semantics; this is harness-compatibility only.
+
+Validation:
+
+- `node tests/phase6/service-behaviour.test.cjs` -> pass (8/8)
+
+Follow-ups:
+
+- Optional consolidation: extract shared phase6/phase7 VM loader helpers into a single test utility to reduce duplication.
