+### CL-081: TASK22269 Slice B1.6 — azurestorage hash-query metadata builder normalization
+
+date: 2026-03-25
+author: Cline
+scope: `actions/azurestorage.js`
+type: change
+rationale: Continue requested follow-on slice by reducing repeated hash-query path string composition in azure storage metadata builders behind local helper functions.
+impact: Lowers duplication/drift risk in hashed metadata path generation while preserving existing route and encoding behavior.
+status: completed
+
+Summary:
+
+- Added internal helper builders in `actions/azurestorage.js`:
+    - `buildDownloadBlobQueryPath(...)`
+    - `buildDeleteBlobQueryPath(...)`
+    - `buildGetBlobListQueryPath(...)`
+- Replaced repeated inline hash path literals with helper usage in targeted metadata object builders:
+    - `getBlobs`
+    - `getProgressBlobs`
+    - `getRepsFilesBlobs`
+- Preserved existing behavior semantics for hash path construction:
+    - encoded `casefolderID`/`blobname` where previously encoded
+    - unchanged `containerName` and `casefolderID` value sourcing
+    - unchanged returned object field names and shape
+
+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:
+
+- Remaining potential cleanups in `actions/azurestorage.js` are broader non-slice refactors (legacy logging verbosity, large function decomposition) and should be handled separately to keep risk bounded.
