+### CL-015: TASK22224 pdf handler dead-code hygiene slice
+
+date: 2026-03-24
+author: Cline
+scope: `pages/api/file/{generatepdf,generateappealpdf}.js`
+type: change
+rationale: Execute the requested next low-risk slice by removing dead imports and unused locals in recently hardened PDF handlers.
+impact: Non-behavioral maintainability cleanup; reduces lint noise and future edit risk while preserving existing contracts.
+status: completed
+
+Summary:
+
+- `pages/api/file/generatepdf.js`
+    - pruned unused Azure storage imports, leaving only `createRepPDFBlob`
+    - pruned unused `@react-pdf/renderer` named imports
+    - removed unused imports (`middleware`, `nextConnect`, `fs`)
+    - removed unused locals (`casefolderID`, `representationType`, `repRaiser`, `localeSelect`, `repCapacity`, `repType`)
+- `pages/api/file/generateappealpdf.js`
+    - pruned unused Azure storage imports to only required functions
+    - pruned unused `@react-pdf/renderer` named imports
+    - removed unused imports (`middleware`, `nextConnect`, `fs`, `path`, unused pdf templates)
+    - removed unused local (`caseRef`)
+
+Validation:
+
+- `node tests/phase21/api-contract-slice1.test.cjs` -> pass
+    - helper: 4/4
+    - file-handler: 53/53
+    - email-handler: 12/12
+    - endpoint-handler: 152/152
+
+Follow-ups:
+
+- Optional: run full repo lint in a separate pass for broader non-slice hygiene now that targeted contract suite is stable.
