+### CL-078: TASK22269 Slice B1.3 — fileClient signed helper delegation bundle
+
+date: 2026-03-25
+author: Cline
+scope: `actions/clients/fileClient.js`, `tests/phase22/file-client-behaviour.test.cjs`
+type: change
+rationale: Continue grouped signed-request consolidation by reducing duplicate signing logic in `fileClient` and delegating signed GET/POST operations to shared `signedRequestClient` helpers.
+impact: Centralizes signed method execution behavior in one helper layer and lowers drift risk across file-service call paths.
+status: completed
+
+Summary:
+
+- Updated `actions/clients/fileClient.js`:
+    - replaced direct `buildHashedQueryUrl + requestJson` logic in:
+        - `getSignedFileJson` -> now delegates to `getSignedJson`
+        - `postSignedFileJson` -> now delegates to `postSignedJson`
+    - retained `downloadFileBlob` and `getFileJson` behavior unchanged.
+- Updated `tests/phase22/file-client-behaviour.test.cjs` to assert delegation contracts for `getSignedJson` and `postSignedJson` rather than direct signing internals.
+
+Validation:
+
+- `npm run lint` -> pass with warnings only (pre-existing `react-hooks/exhaustive-deps`; no new lint errors)
+- `node tests/phase22/index.test.cjs` -> pass
+- `node tests/phase7/service-behaviour.test.cjs` -> pass (13/13)
+
+Follow-ups:
+
+- Candidate map now indicates remaining explicit signed request composition is primarily in account/portal signed GET edge paths (`getPortalLogin`, `sendRepCompleteMessage`, and signed suffix append flow in `sendCaseCompleteMessage`) for future bounded slices.
