+### CL-018: TASK22224 nextauth notify micro-refactor
+
+date: 2026-03-24
+author: Cline
+scope: `pages/api/auth/[...nextauth].js`
+type: change
+rationale: Execute the explicitly approved auth micro-slice by replacing inline promise `.catch(...)` with explicit `try/catch` while preserving existing auth behavior.
+impact: Auth-sensitive non-functional refactor only; keeps current sign-in flow, template/locale routing, and error-handling semantics unchanged.
+status: completed
+
+Summary:
+
+- `pages/api/auth/[...nextauth].js`
+    - replaced:
+        - `await notifyClient.sendEmail(...).catch((error) => consoleLogger(error))`
+    - with explicit:
+        - `try { await notifyClient.sendEmail(...) } catch (error) { consoleLogger(error) }`
+- preserved behavior contracts:
+    - Notify failures are still logged and do not throw through auth handler
+    - no changes to callback URL construction, locale/template selection, NextAuth options, session/cookies/pages config
+
+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
+    - documents-handler: 3/3
+
+Follow-ups:
+
+- Optional future auth hygiene (separate guarded slice): replace verbose auth `console.log` diagnostics with structured logger usage once production logging requirements are confirmed.
