- Introduced a new `AccountStatusResult` interface to standardize account status detection across systems.
- Updated the `VerificationWorkflowService` to merge handoff data with discovered account status.
- Enhanced error handling in `GlobalAuthGuard` and `LocalAuthGuard` to include structured error codes for better clarity in unauthorized responses.
- Refined WHMCS and Salesforce integration schemas to ensure consistent data validation and coercion.
Comprehensive refactoring across 70 files (net -298 lines) improving
type safety, error handling, and code organization:
- Replace .passthrough()/.catchall(z.unknown()) with .strip() in all Zod schemas
- Tighten Record<string, unknown> to bounded union types where possible
- Replace throw new Error with domain-specific exceptions (OrderException,
FulfillmentException, WhmcsOperationException, SalesforceOperationException, etc.)
- Split AuthTokenService (625 lines) into TokenGeneratorService and
TokenRefreshService with thin orchestrator
- Deduplicate FreebitClientService with shared makeRequest() method
- Add typed interfaces to WHMCS facade, order service, and fulfillment mapper
- Externalize hardcoded config values to ConfigService with env fallbacks
- Consolidate duplicate billing cycle enums into shared billingCycleSchema
- Standardize logger usage (nestjs-pino @Inject(Logger) everywhere)
- Move shared WHMCS number coercion helpers to whmcs-utils/schema.ts
- Refactor various mappers in billing, payments, services, and subscriptions to ensure IDs are consistently converted to numbers.
- Update raw types schemas to utilize whmcsNumberLike and whmcsString for improved validation and type safety.
- Enhance the whmcs-utils to include schema exports for better modularity.
