feat: implement Result types for type-safe error handling (Phase 1.1)
...
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)
