+# Issue #182: [BLOCKER] Fix failing Prisma enum import tests in job-steps.service.spec.ts
+
+## Objective
+
+Fix Prisma enum import issues in job-steps.service.spec.ts that are causing test failures and blocking other work.
+
+## Approach
+
+1. Read the failing test file to understand the issue
+2. Check the Prisma schema to understand the correct enum definitions
+3. Fix the enum imports and usage in the test file
+4. Run tests to verify the fix
+5. Ensure 85% coverage is maintained
+
+## Progress
+
+- [x] Read job-steps.service.spec.ts
+- [x] Read Prisma schema to verify enum definitions
+- [x] Identify the root cause of the import failures
+- [x] Fix enum imports and usage
+- [x] Run tests to verify fix
+- [x] Run full test suite to check for regressions
+- [x] Verify test coverage (16/16 tests passing)
+- [ ] Commit changes
+
+## Root Cause Analysis
+
+The test file imports `JobStepPhase`, `JobStepType`, and `JobStepStatus` from `@prisma/client`:
+
+```typescript
+import { JobStepPhase, JobStepType, JobStepStatus } from "@prisma/client";
+```
+
+However, in the test environment with mocked Prisma, these enum imports are undefined, causing errors like:
+
+- `Cannot read properties of undefined (reading 'SETUP')`
+- `Cannot read properties of undefined (reading 'COMPLETED')`
+
+The Prisma schema defines these enums at lines 147-167:
+
+- `JobStepPhase`: SETUP, EXECUTION, VALIDATION, CLEANUP
+- `JobStepType`: COMMAND, AI_ACTION, GATE, ARTIFACT
+- `JobStepStatus`: PENDING, RUNNING, COMPLETED, FAILED, SKIPPED
+
+## Solution
+
+Instead of importing from `@prisma/client`, we need to manually define these enums in the test file or import them from the DTOs which properly export the types. Since the DTOs already import from `@prisma/client`, we'll define the enum constants directly in the test file to avoid circular dependencies.
+
+### Implementation
+
+Used `vi.mock()` with `importOriginal` to mock the `@prisma/client` module and provide the enum values:
+
+```typescript
+vi.mock("@prisma/client", async (importOriginal) => {
+  const actual = await importOriginal<typeof import("@prisma/client")>();
+  return {
+    ...actual,
+    JobStepPhase: {
+      SETUP: "SETUP",
+      EXECUTION: "EXECUTION",
+      VALIDATION: "VALIDATION",
+      CLEANUP: "CLEANUP",
+    },
+    JobStepType: {
+      COMMAND: "COMMAND",
+      AI_ACTION: "AI_ACTION",
+      GATE: "GATE",
+      ARTIFACT: "ARTIFACT",
+    },
+    JobStepStatus: {
+      PENDING: "PENDING",
+      RUNNING: "RUNNING",
+      COMPLETED: "COMPLETED",
+      FAILED: "FAILED",
+      SKIPPED: "SKIPPED",
+    },
+  };
+});
+```
+
+This approach:
+
+1. Imports the actual Prisma client using `importOriginal`
+2. Spreads the actual exports to preserve PrismaClient and other types
+3. Overrides only the enum values that were undefined in the test environment
+4. Must be placed BEFORE importing any modules that depend on @prisma/client

+- `/home/localadmin/src/mosaic-stack/apps/api/src/job-steps/job-steps.controller.spec.ts`
+
+## Testing
+
+- Run unit tests: `pnpm test:api`
+- Verify coverage: `pnpm test:coverage`
+
+## Notes
+
+- This is a BLOCKER issue - must be resolved before other work can proceed
+- Need to maintain minimum 85% coverage
