+### CL-056: TASK22260 next slice — document direct service download helper contract fix
+
+date: 2026-03-25
+author: Cline
+scope: `actions/services/documentDirectService.js`
+type: change
+rationale: Execute the next bounded follow-up by correcting the legacy `downloadBlob` service helper path that still relied on invalid `res` references and direct axios usage, aligning it to shared request client behavior.
+impact: Fixes a service-layer contract defect risk in document download helper and improves consistency by using shared request client patterns; no endpoint contract change.
+status: completed
+
+Summary:
+
+- Refactored `downloadBlob(containerName, blobName)` in `documentDirectService`:
+    - removed legacy direct `axios.get(...).then(response => res.status(...))` pattern that referenced undefined `res` in service layer
+    - now returns blob response data via `requestJson({ method: "get", url, responseType: "blob" })`
+    - preserved catch-path logging (`consoleLogger`)
+- Removed now-unused module-level `axios` import from `documentDirectService`.
+
+Validation:
+
+- `npm run lint` -> warnings only (pre-existing `react-hooks/exhaustive-deps`; no new lint errors)
+
+Follow-ups:
+
+- Optional next bounded slice: add a focused test (or integration harness assertion) around `downloadBlob` service return contract to prevent regression to response-object assumptions.
