Replace throw/catch patterns with explicit Result types throughout the codebase. This provides type-safe error handling and better user-facing error messages. ## Changes ### Core Type System (src/types.ts) - Add Result<T, E> discriminated union type - Add AsyncResult<T, E> for promises - Add helper functions: Ok(), Err(), tryCatch(), tryCatchAsync() ### Crypto Module (src/lib/crypto.ts) - Update parsePublicKeyFromCert() to return Result<PublicKey, string> - Update encryptValue() to return Result<string, string> - Update encryptKeyValues() to return Result<Record<string, string>, string> - Early return on first encryption failure with detailed error ### Controller API (src/lib/controller.ts) - Update fetchPublicCertificate() to return AsyncResult<string, string> - Update verifySealedSecret() to return AsyncResult<boolean, string> - Update rotateSealedSecret() to return AsyncResult<string, string> - Use tryCatchAsync() for HTTP operations ### UI Components - EncryptDialog: Explicit error checking at each step with specific messages - SealingKeysView: Type-safe certificate download with error handling - DecryptDialog: Import cleanup (auto-fixed by linter) - SealedSecretDetail: Unused import removed (auto-fixed by linter) ### Documentation - ENHANCEMENT_PLAN.md: Comprehensive 4-phase enhancement roadmap - PHASE_1.1_COMPLETE.md: Detailed implementation summary - BUILD_VERIFICATION_SUMMARY.md: Build metrics and verification results - DEVELOPMENT.md: Development workflow guide - TESTING_GUIDE.md: Manual testing procedures - READY_FOR_TESTING.md: Quick-start testing guide ### Development Tools - Add 5 specialized Claude Code subagents to .claude/agents/ - typescript-pro: TypeScript expertise - kubernetes-specialist: K8s best practices - react-specialist: React optimization - security-auditor: Security review - code-reviewer: Code quality ## Benefits - Type Safety: Errors are now part of type signatures - Better UX: Specific error messages at each operation step - Maintainability: Error paths are explicit and visible - No Hidden Exceptions: All error cases handled explicitly ## Verification - TypeScript: 0 errors - Linting: All checks pass - Build: 340.13 kB (93.40 kB gzipped, +0.2%) - Package: Successfully created ## Breaking Changes None for users. Internal API signatures changed but plugin behavior is backward compatible. ## Testing See TESTING_GUIDE.md for detailed test scenarios: - Happy path: Create sealed secret with valid controller - Error path: Try with controller unreachable - Console check: Verify no uncaught exceptions Run: npm start (in headlamp-sealed-secrets directory) Generated with [Claude Code](https://claude.ai/code) via [Happy](https://happy.engineering) Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com> Co-Authored-By: Happy <yesreply@happy.engineering>
