+### CL-088: TASK22269 Slice B1.13 — azurestorage touched-function caseObj helper reuse
+
+date: 2026-03-26
+author: Cline
+scope: `actions/azurestorage.js`
+type: change
+rationale: Execute the next bounded readability slice by centralizing repeated case-object path composition in touched helper-consumer functions.
+impact: Maintainability/readability improvement only; no route/query behavior changes.
+status: completed
+
+Summary:
+
+- Added local helper `buildCaseObjectPath(casefolderID)`.
+- Replaced repeated `caseObj` string assembly in touched functions:
+    - `getBlobs`
+    - `getProgressBlobs`
+- Preserved existing `caseObj` output format (`<caseRef>/<caseRef>_case.json`).
+
+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:
+
+- Optional next bounded slice: continue tiny helper reuse in touched functions only if any duplicated path literals remain and can be reduced without behavior change.
