**Resolution:** Added 5 method variants matching oauth_service.go expectations
**Verification:** All 15+ event publisher tests passing ✅

### 2. Temporal Package Compilation (T+50)
**Issue:** Neo4j v5 API signature mismatches in activities.go
**Root Cause:** Code using deprecated Neo4j v4 API
**Resolution:** Corrected NewSession() and session.Close() calls
**Verification:** Temporal tests passing ✅, `go build ./...` clean ✅

### 3. JSX/TypeScript Namespace (Earlier)
**Issue:** React JSX references in frontend tests
**Resolution:** Added React type reference pragmas
**Verification:** Frontend build passing ✅
