+### CL-083: TASK22269 Slice B1.8 — phase22 azurestorage helper contract coverage
+
+date: 2026-03-26
+author: Cline
+scope: `tests/phase22/{azurestorage-helper-behaviour,index}.test.cjs`
+type: change
+rationale: Execute the selected bounded test-only follow-up by adding focused regression coverage for recently added azurestorage helper contracts.
+impact: Improves confidence in query-path and hash-metadata helper output stability without changing runtime behavior.
+status: completed
+
+Summary:
+
+- Added new phase22 suite: `tests/phase22/azurestorage-helper-behaviour.test.cjs`.
+- Test suite isolates helper block from `actions/azurestorage.js` and verifies:
+    - `buildDownloadBlobQueryPath` default encoding output
+    - `buildDeleteBlobQueryPath` non-encoded option behavior
+    - `buildGetBlobListQueryPath` query output contract
+    - `buildHashMetadataPaths` key/value shape (`hashedfilepath`, `hasheddeletepath`, `hashgetblobs`)
+- Wired suite into aggregate runner `tests/phase22/index.test.cjs`.
+
+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 (includes new azurestorage-helper 4/4)
+- `node tests/phase7/service-behaviour.test.cjs` -> pass (13/13)
+
+Follow-ups:
+
+- Optional next bounded slice: add an explicit assertion for encoded `casefolderID` variants containing reserved query characters (`?`, `&`) if those inputs are expected in future flows.
