- Replace simple ternary assignment with let schema pattern
- Chain (schema as z.ZodString).regex() when field.validate is present
- Handle optional fields: z.string() first, then .regex() if needed, then .optional()
- VALID-01 tests all pass (GREEN): azureblob account, s3 region, gcs project_number
- buildZodSchema derives z.object() from BACKEND_REGISTRY field definitions
- required fields map to z.string().min(1, label) — optional to z.string().optional()
- BACKEND_SCHEMAS exported with entries for azureblob, s3, s3-compatible
- BackendFormValues<T> utility type infers TypeScript type from schema
- No hardcoded field names — all shapes derived from registry loop
- All 8 tests in index.test.ts pass (GREEN)
