+# ADR-060: TypeScript Test Error Remediation Strategy
+
+**Date**: 2026-02-17
+
+**Status**: Implemented
+
+**Completed**: 2026-02-17
+
+**Context**: Systematic remediation of 185 TypeScript errors in test files following API response standardization (ADR-028) and tsoa migration (ADR-059)
+
+## Implementation Summary
+
+This ADR has been fully implemented. The remediation project achieved:
+
+| Metric               | Value                                       |
+| -------------------- | ------------------------------------------- |
+| Initial Errors       | 185                                         |
+| Final Errors         | 0                                           |
+| Files Modified       | 19 controller test files + shared utilities |
+| Test Suite           | 4,603 passed, 59 failed (all pre-existing)  |
+| Net Test Improvement | +3 tests fixed                              |
+
+### Implementation Phases Completed
+
+| Phase                       | Duration  | Errors Fixed                       |
+| --------------------------- | --------- | ---------------------------------- |
+| Phase 1: Foundation         | Completed | Infrastructure (enables all fixes) |
+| Phase 2-4: Parallel Tasks   | 3 rounds  | 185 -> 114 -> 67 -> 23 -> 0        |
+| Phase 5: Final Verification | Completed | All type-check passes              |
+
+### Artifacts Created
+
+1. **Shared Test Utilities** (`src/tests/utils/testHelpers.ts`):
+   - `asSuccessResponse<T>()` - Type guard for success responses
+   - `asErrorResponse()` - Type guard for error responses
+   - `asMock<T>()` - Mock function type casting
+   - Re-export of `createMockLogger`
+
+2. **Mock Logger** (`src/tests/utils/mockLogger.ts`):
+   - `createMockLogger()` - Complete Pino logger mock
+   - `mockLogger` - Pre-instantiated mock for convenience
+
+3. **Updated Mock Factories** (`src/tests/utils/mockFactories.ts`):
+   - 60+ type-safe mock factory functions
+   - Deterministic ID generation with `getNextId()`
+   - Complete type coverage for all domain entities
+
+## Context
+
+Following the implementation of ADR-028 (API Response Standardization) and ADR-059 (tsoa Migration), 185 TypeScript errors accumulated in test files. The errors stem from stricter type checking on API response handling, mock type mismatches, and response body access patterns. This ADR documents the systematic analysis, categorization, and phased remediation approach.
+
+### Error Distribution
+
+| Category                        | Count | Percentage |
+| ------------------------------- | ----- | ---------- |
+| SuccessResponse type narrowing  | 89    | 48.1%      |
+| Mock object type casting        | 42    | 22.7%      |
+| Response body property access   | 28    | 15.1%      |
+| Partial mock missing properties | 18    | 9.7%       |
+| Generic type parameter issues   | 5     | 2.7%       |
+| Module import type issues       | 3     | 1.6%       |
+
+### Root Cause Analysis
+
+1. **SuccessResponse Discriminated Union**: ADR-028 introduced `ApiSuccessResponse<T> | ApiErrorResponse` union types. Tests accessing `response.body.data` without type guards trigger TS2339 errors.
+
+2. **Mock Type Strictness**: Vitest mocks return `MockedFunction<T>` types. Passing to functions expecting exact signatures requires explicit casting.
+
+3. **Partial<T> vs Full Object**: Factory functions creating partial mocks lack required properties. Tests using spread operators without type assertions fail property access.
+
+4. **Response Body Type Unknown**: Supertest `response.body` is typed as `unknown` or `any`. Direct property access without narrowing violates strict mode.
+
+## Decision
+
+Implement a 5-phase remediation strategy with parallelizable tasks, prioritized by error count per file and criticality.
+
+### Phase 1: High-Impact Infrastructure (Est. 2 hours)
+
+**Goal**: Fix foundational patterns that propagate to multiple files.
+
+| Task                                                  | Files                              | Errors Fixed     |
+| ----------------------------------------------------- | ---------------------------------- | ---------------- |
+| Add `asSuccessResponse<T>()` type guard to test utils | `src/tests/utils/testHelpers.ts`   | Enables 89 fixes |
+| Add `asMock<T>()` utility for mock casting            | `src/tests/utils/testHelpers.ts`   | Enables 42 fixes |
+| Update mock factories with strict return types        | `src/tests/utils/mockFactories.ts` | 18               |
+
+**Type Guard Implementation**:
+
+```typescript
+// src/tests/utils/testHelpers.ts
+
+import { ApiSuccessResponse, ApiErrorResponse } from '@/types/api';
+
+/**
+ * Type guard to narrow supertest response body to ApiSuccessResponse.
+ * Use when accessing .data property on API responses in tests.
+ *
+ * @example
+ * const response = await request.get('/api/v1/users/1');
+ * const body = asSuccessResponse<User>(response.body);
+ * expect(body.data.id).toBe(1); // TypeScript knows body.data exists
+ */
+export function asSuccessResponse<T>(body: unknown): ApiSuccessResponse<T> {
+  const parsed = body as ApiSuccessResponse<T> | ApiErrorResponse;
+  if (parsed.success !== true) {
+    throw new Error(`Expected success response, got: ${JSON.stringify(parsed)}`);
+  }
+  return parsed;
+}
+
+/**
+ * Type guard for error responses.
+ */
+export function asErrorResponse(body: unknown): ApiErrorResponse {
+  const parsed = body as ApiSuccessResponse<unknown> | ApiErrorResponse;
+  if (parsed.success !== false) {
+    throw new Error(`Expected error response, got: ${JSON.stringify(parsed)}`);
+  }
+  return parsed;
+}
+
+/**
+ * Cast Vitest mock to specific function type.
+ * Use when passing mocked functions to code expecting exact signatures.
+ *
+ * @example
+ * const mockFn = vi.fn();
+ * someService.register(asMock<UserService['create']>(mockFn));
+ */
+export function asMock<T extends (...args: unknown[]) => unknown>(
+  mock: ReturnType<typeof vi.fn>,
+): T {
+  return mock as unknown as T;
+}
+```
+
+### Phase 2: Route Test Files (Est. 3 hours)
+
+**Priority**: Files with 10+ errors first.
+
+| File                                      | Errors | Pattern                                |
+| ----------------------------------------- | ------ | -------------------------------------- |
+| `src/routes/flyer.routes.test.ts`         | 24     | Response body narrowing                |
+| `src/routes/user.routes.test.ts`          | 18     | Response body narrowing                |
+| `src/routes/auth.routes.test.ts`          | 15     | Response body narrowing                |
+| `src/routes/recipe.routes.test.ts`        | 12     | Response body narrowing                |
+| `src/routes/shopping-list.routes.test.ts` | 11     | Response body narrowing                |
+| `src/routes/notification.routes.test.ts`  | 9      | Response body narrowing                |
+| `src/routes/inventory.routes.test.ts`     | 8      | Response body narrowing                |
+| `src/routes/budget.routes.test.ts`        | 7      | Response body narrowing                |
+| `src/routes/admin.routes.test.ts`         | 6      | Response body narrowing + mock casting |
+
+**Fix Pattern**:
+
+```typescript
+// BEFORE (TS2339: Property 'data' does not exist on type 'unknown')
+const response = await request.get('/api/v1/flyers/1');
+expect(response.body.data.flyer_id).toBe(1);
+
+// AFTER
+import { asSuccessResponse } from '@/tests/utils/testHelpers';
+import { Flyer } from '@/types/flyer';
+
+const response = await request.get('/api/v1/flyers/1');
+const body = asSuccessResponse<Flyer>(response.body);
+expect(body.data.flyer_id).toBe(1);
+```
+
+### Phase 3: Service Test Files (Est. 2 hours)
+
+**Priority**: Mock casting issues.
+
+| File                                              | Errors | Pattern            |
+| ------------------------------------------------- | ------ | ------------------ |
+| `src/services/db/flyer.db.test.ts`                | 8      | Pool mock typing   |
+| `src/services/db/user.db.test.ts`                 | 7      | Pool mock typing   |
+| `src/services/aiService.server.test.ts`           | 6      | Gemini mock typing |
+| `src/services/cacheService.server.test.ts`        | 5      | Redis mock typing  |
+| `src/services/notificationService.server.test.ts` | 4      | Queue mock typing  |
+
+**Mock Casting Pattern**:
+
+```typescript
+// BEFORE (TS2345: Argument of type 'Mock' is not assignable)
+const mockPool = { query: vi.fn() };
+const service = new FlyerService(mockPool);
+
+// AFTER
+import { Pool } from 'pg';
+
+const mockPool = {
+  query: vi.fn().mockResolvedValue({ rows: [], rowCount: 0 }),
+} as unknown as Pool;
+const service = new FlyerService(mockPool);
+```
+
+### Phase 4: Integration Test Files (Est. 1.5 hours)
+
+| File                                              | Errors | Pattern                 |
+| ------------------------------------------------- | ------ | ----------------------- |
+| `src/tests/integration/flyer.integration.test.ts` | 6      | Response body + cleanup |
+| `src/tests/integration/auth.integration.test.ts`  | 5      | Response body           |
+| `src/tests/integration/user.integration.test.ts`  | 4      | Response body           |
+| `src/tests/integration/admin.integration.test.ts` | 4      | Response body           |
+
+**Integration Test Pattern**:
+
+```typescript
+// Establish typed response helper at top of file
+const expectSuccess = <T>(response: Response) => {
+  expect(response.status).toBeLessThan(400);
+  return asSuccessResponse<T>(response.body);
+};
+
+// Usage
+const body = expectSuccess<{ token: string }>(response);
+expect(body.data.token).toBeDefined();
+```
+
+### Phase 5: Component and Hook Tests (Est. 1.5 hours)
+
+| File                          | Errors | Pattern             |
+| ----------------------------- | ------ | ------------------- |
+| `src/hooks/useFlyers.test.ts` | 3      | MSW response typing |
+| `src/hooks/useAuth.test.ts`   | 3      | MSW response typing |
+| Various component tests       | 8      | Mock prop typing    |
+
+**MSW Handler Pattern**:
+
+```typescript
+// BEFORE
+http.get('/api/v1/flyers', () => {
+  return HttpResponse.json({ data: [mockFlyer] });
+});
+
+// AFTER
+import { ApiSuccessResponse } from '@/types/api';
+import { Flyer } from '@/types/flyer';
+
+http.get('/api/v1/flyers', () => {
+  const response: ApiSuccessResponse<Flyer[]> = {
+    success: true,
+    data: [mockFlyer],
+  };
+  return HttpResponse.json(response);
+});
+```
+
+## Implementation Guidelines
+
+### 1. Mock Object Casting Hierarchy
+
+Use the least permissive cast that satisfies TypeScript:
+
+```typescript
+// Level 1: Type assertion for compatible shapes
+const mock = createMockUser() as User;
+
+// Level 2: Unknown bridge for incompatible shapes
+const mock = partialMock as unknown as User;
+
+// Level 3: Partial with required overrides
+const mock: User = { ...createPartialUser(), id: 1, email: 'test@test.com' };
+```
+
+### 2. Response Type Narrowing
+
+**Always narrow before property access**:
+
+```typescript
+// Standard pattern
+const body = asSuccessResponse<ExpectedType>(response.body);
+expect(body.data.property).toBe(value);
+
+// With error expectation
+expect(response.status).toBe(400);
+const body = asErrorResponse(response.body);
+expect(body.error.code).toBe('VALIDATION_ERROR');
+```
+
+### 3. Mock Function Type Safety
+
+```typescript
+// vi.fn() with implementation type
+const mockFn = vi.fn<[string], Promise<User>>().mockResolvedValue(mockUser);
+
+// Mocked module function
+vi.mock('@/services/userService');
+const mockedService = vi.mocked(userService);
+mockedService.create.mockResolvedValue(mockUser);
+```
+
+### 4. Generic Type Parameters
+
+When TypeScript cannot infer generics, provide explicit parameters:
+
+```typescript
+// Explicit generic on factory
+const mock = createMockPaginatedResponse<Flyer>({ data: [mockFlyer] });
+
+// Explicit generic on assertion
+expect(result).toEqual<ApiSuccessResponse<User>>({
+  success: true,
+  data: mockUser,
+});
+```
+
+## Parallelization Strategy
+
+### Parallel Execution Groups
+
+Tests can be fixed in parallel within these independent groups:
+
+| Group | Files                                             | Dependencies      |
+| ----- | ------------------------------------------------- | ----------------- |
+| A     | Route tests (auth, user, flyer)                   | Phase 1 utilities |
+| B     | Route tests (recipe, shopping-list, notification) | Phase 1 utilities |
+| C     | Service tests (db layer)                          | None              |
+| D     | Service tests (external services)                 | None              |
+| E     | Integration tests                                 | Phase 1 utilities |
+| F     | Component/hook tests                              | None              |
+
+**Dependency Graph**:
+
+```
+Phase 1 (Infrastructure)
+    │
+    ├── Group A ─┐
+    ├── Group B ─┼── Can run in parallel
+    └── Group E ─┘
+
+Groups C, D, F have no dependencies (can start immediately)
+```
+
+### Critical Path
+
+Minimum time to completion: **Phase 1 (2h) + longest parallel group (1.5h) = 3.5 hours**
+
+Sequential worst case: **10 hours** (if no parallelization)
+
+## Testing Strategy
+
+### Execution Environment
+
+**All tests MUST run in the dev container** per ADR-014:
+
+```bash
+# Type check (fast verification)
+podman exec -it flyer-crawler-dev npm run type-check
+
+# Unit tests (after type check passes)
+podman exec -it flyer-crawler-dev npm run test:unit
+
+# Full suite (final verification)
+podman exec -it flyer-crawler-dev npm test
+```
+
+### Background Job Execution (MCP)
+
+For long-running test suites, use the MCP background-job tools:
+
+```bash
+# Estimate duration first
+mcp__background-job__estimate_command_duration("npm run type-check")
+
+# Execute in background
+mcp__background-job__execute_command("npm run type-check")
+
+# Poll status per guidelines (15-30s intervals)
+mcp__background-job__get_job_status(job_id)
+```
+
+### Incremental Verification
+
+After each phase, verify:
+
+1. **Type check passes**: `npm run type-check` exits 0
+2. **Affected tests pass**: Run specific test file
+3. **No regressions**: Run full unit suite
+
+## Consequences
+
+### Positive
+
+1. **Type Safety**: All test files will have proper TypeScript coverage
+2. **IDE Support**: IntelliSense works correctly for response bodies
+3. **Refactoring Safety**: Type errors will catch API contract changes
+4. **Pattern Consistency**: Established patterns for future test writing
+5. **Reusable Utilities**: `asSuccessResponse`, `asMock` utilities for all tests
+
+### Negative
+
+1. **Verbosity**: Tests require explicit type narrowing (2-3 extra lines)
+2. **Maintenance**: Type parameters must match actual API responses
+3. **Learning Curve**: Contributors must learn type guard patterns
+
+### Neutral
+
+1. **Test Execution**: No runtime performance impact (compile-time only)
+2. **Coverage**: No change to test coverage metrics
+
+## File Priority Matrix
+

+# ADR-061: PM2 Process Isolation Safeguards
+
+## Status
+
+Accepted
+
+## Context
+
+On 2026-02-17, a critical incident occurred during v0.15.0 production deployment where ALL PM2 processes on the production server were terminated, not just flyer-crawler processes. This caused unplanned downtime for multiple applications including `stock-alert.projectium.com`.
+
+### Problem Statement
+
+Production and test environments share the same PM2 daemon on the server. This creates a risk where deployment scripts that operate on PM2 processes can accidentally affect processes belonging to other applications or environments.
+
+### Pre-existing Controls
+
+Prior to the incident, PM2 process isolation controls were already in place (commit `b6a62a0`):
+
+- Production workflows used whitelist-based filtering with explicit process names
+- Test workflows filtered by `-test` suffix pattern
+- CLAUDE.md documented the prohibition of `pm2 stop all`, `pm2 delete all`, and `pm2 restart all`
+
+Despite these controls being present in the codebase and included in v0.15.0, the incident still occurred. The leading hypothesis is that the Gitea runner executed a cached/older version of the workflow file.
+
+### Requirements
+
+1. Prevent accidental deletion of processes from other applications or environments
+2. Provide audit trail for forensic analysis when incidents occur
+3. Enable automatic abort when dangerous conditions are detected
+4. Maintain visibility into PM2 operations during deployment
+5. Work correctly even if the filtering logic itself is bypassed
+
+## Decision
+
+Implement a defense-in-depth strategy with 5 layers of safeguards in all deployment workflows that interact with PM2 processes.
+
+### Safeguard Layers
+
+#### Layer 1: Workflow Metadata Logging
+
+Log workflow execution metadata at the start of each deployment:
+
+```bash
+echo "=== WORKFLOW METADATA ==="
+echo "Workflow file: deploy-to-prod.yml"
+echo "Workflow file hash: $(sha256sum .gitea/workflows/deploy-to-prod.yml | cut -d' ' -f1)"
+echo "Git commit: $(git rev-parse HEAD)"
+echo "Git branch: $(git rev-parse --abbrev-ref HEAD)"
+echo "Timestamp: $(date -u '+%Y-%m-%d %H:%M:%S UTC')"
+echo "Actor: ${{ gitea.actor }}"
+echo "=== END METADATA ==="
+```
+
+**Purpose**: Enables verification of which workflow version was actually executed.
+
+#### Layer 2: Pre-Cleanup PM2 State Logging
+
+Capture full PM2 process list before any modifications:
+
+```bash
+echo "=== PRE-CLEANUP PM2 STATE ==="
+pm2 jlist
+echo "=== END PRE-CLEANUP STATE ==="
+```
+
+**Purpose**: Provides forensic evidence of system state before cleanup.
+
+#### Layer 3: Process Count Validation (SAFETY ABORT)
+
+Abort deployment if the filter would delete ALL processes and there are more than 3 processes total:
+
+```javascript
+const totalProcesses = list.length;
+if (targetProcesses.length === totalProcesses && totalProcesses > 3) {
+  console.error('SAFETY ABORT: Filter would delete ALL processes!');
+  console.error(
+    'Total processes: ' + totalProcesses + ', Target processes: ' + targetProcesses.length,
+  );
+  process.exit(1);
+}
+```
+
+**Purpose**: Catches filter bugs or unexpected conditions automatically.
+
+**Threshold Rationale**: A threshold of 3 allows normal operation when only the expected processes exist (API, Worker, Analytics Worker) while catching anomalies when the server hosts additional applications.
+
+#### Layer 4: Explicit Name Verification
+
+Log the exact name, status, and PM2 ID of each process that will be affected:
+
+```javascript
+console.log('Found ' + targetProcesses.length + ' PRODUCTION processes to clean:');
+targetProcesses.forEach((p) => {
+  console.log(
+    '  - ' + p.name + ' (status: ' + p.pm2_env.status + ', pm_id: ' + p.pm2_env.pm_id + ')',
+  );
+});
+```
+
+**Purpose**: Provides clear visibility into cleanup operations.
+
+#### Layer 5: Post-Cleanup Verification
+
+After cleanup, verify environment isolation was maintained:
+
+```bash
+echo "=== POST-CLEANUP VERIFICATION ==="
+pm2 jlist | node -e "
+  const list = JSON.parse(require('fs').readFileSync(0, 'utf-8'));
+  const prodProcesses = list.filter(p => p.name && p.name.startsWith('flyer-crawler-') && !p.name.endsWith('-test'));
+  console.log('Production processes after cleanup: ' + prodProcesses.length);
+"
+echo "=== END POST-CLEANUP VERIFICATION ==="
+```
+
+**Purpose**: Immediately identifies cross-environment contamination.
+
+## Consequences
+
+### Positive
+
+1. **Automatic Prevention**: Layer 3 (process count validation) can prevent catastrophic process deletion automatically, without human intervention.
+
+2. **Forensic Capability**: Layers 1 and 2 provide the data needed to determine root cause after an incident.
+
+3. **Visibility**: Layers 4 and 5 make PM2 operations transparent in workflow logs.
+
+4. **Fail-Safe Design**: Even if individual layers fail, other layers provide backup protection.
+
+5. **Non-Breaking**: Safeguards are additive and do not change the existing filtering logic.
+
+### Negative
+
+1. **Increased Log Volume**: Additional logging increases workflow output size.
+
+2. **Minor Performance Impact**: Extra PM2 commands add a few seconds to deployment time.
+
+3. **Threshold Tuning**: The threshold of 3 may need adjustment if the expected process count changes.
+
+### Neutral
+
+1. **Root Cause Still Unknown**: These safeguards mitigate the risk but do not definitively explain why the original incident occurred.
+
+2. **No Structural Changes**: The underlying architecture (shared PM2 daemon) remains unchanged.
+
+## Alternatives Considered
+
+### PM2 Namespaces
+
+PM2 supports namespaces to isolate groups of processes. This would provide complete isolation but requires:
+
+- Changes to ecosystem config files
+- Changes to all PM2 commands in workflows
+- Potential breaking changes to monitoring and log aggregation
+
+**Decision**: Deferred for future consideration. Current safeguards provide adequate protection.
+
+### Separate PM2 Daemons
+
+Running a separate PM2 daemon per application would eliminate cross-application risk entirely.
+
+**Decision**: Not implemented due to increased operational complexity and the current safeguards being sufficient.
+
+### Deployment Locks
+
+Implementing mutex-style locks to prevent concurrent deployments could prevent race conditions.
+
+**Decision**: Not implemented as the current safeguards address the identified risk. May be reconsidered if concurrent deployment issues are observed.
+
+## Implementation

+# PM2 Process Isolation Safeguards Project
+
+**Session Date**: 2026-02-17
+**Status**: Completed
+**Triggered By**: Critical production incident during v0.15.0 deployment
+
+---
+
+## Executive Summary
+
+On 2026-02-17, a critical incident occurred during v0.15.0 production deployment where ALL PM2 processes on the production server were killed, not just the flyer-crawler processes. This caused unplanned downtime for multiple applications including `stock-alert.projectium.com`.
+
+Despite PM2 process isolation fixes already being in place (commit `b6a62a0`), the incident still occurred. Investigation suggests the Gitea runner may have executed a cached/older version of the workflow files. In response, we implemented a comprehensive defense-in-depth strategy with 5 layers of safeguards across all deployment workflows.
+
+---
+
+## Incident Background
+
+### What Happened
+
+| Aspect                | Detail                                                  |
+| --------------------- | ------------------------------------------------------- |
+| **Date/Time**         | 2026-02-17 ~07:40 UTC                                   |
+| **Trigger**           | v0.15.0 production deployment via `deploy-to-prod.yml`  |
+| **Impact**            | ALL PM2 processes killed (all environments)             |
+| **Collateral Damage** | `stock-alert.projectium.com` and other PM2-managed apps |
+| **Severity**          | P1 - Critical                                           |
+
+### Key Mystery
+
+The PM2 process isolation fix was already implemented in commit `b6a62a0` (2026-02-13) and was included in v0.15.0. The fix correctly used whitelist-based filtering:
+
+```javascript
+const prodProcesses = [
+  'flyer-crawler-api',
+  'flyer-crawler-worker',
+  'flyer-crawler-analytics-worker',
+];
+list.forEach((p) => {
+  if (
+    (p.pm2_env.status === 'errored' || p.pm2_env.status === 'stopped') &&
+    prodProcesses.includes(p.name)
+  ) {
+    exec('pm2 delete ' + p.pm2_env.pm_id);
+  }
+});
+```
+
+**Hypothesis**: Gitea runner executed a cached older version of the workflow file that did not contain the fix.
+
+---
+
+## Solution: Defense-in-Depth Safeguards
+
+Rather than relying solely on the filter logic (which may be correct but not executed), we implemented 5 layers of safeguards that provide visibility, validation, and automatic abort capabilities.
+
+### Safeguard Layers
+
+| Layer | Name                              | Purpose                                                 |
+| ----- | --------------------------------- | ------------------------------------------------------- |
+| 1     | **Workflow Metadata Logging**     | Audit trail of which workflow version actually executed |
+| 2     | **Pre-Cleanup PM2 State Logging** | Capture full process list before any modifications      |
+| 3     | **Process Count Validation**      | SAFETY ABORT if filter would delete ALL processes       |
+| 4     | **Explicit Name Verification**    | Log exactly which processes will be affected            |
+| 5     | **Post-Cleanup Verification**     | Verify environment isolation after cleanup              |
+
+### Layer Details
+
+#### Layer 1: Workflow Metadata Logging
+
+Logs at the start of deployment:
+
+- Workflow file name
+- SHA-256 hash of the workflow file
+- Git commit being deployed
+- Git branch
+- Timestamp (UTC)
+- Actor (who triggered the deployment)
+
+**Purpose**: If an incident occurs, we can verify whether the executed workflow matches the repository version.
+
+```bash
+echo "=== WORKFLOW METADATA ==="
+echo "Workflow file: deploy-to-prod.yml"
+echo "Workflow file hash: $(sha256sum .gitea/workflows/deploy-to-prod.yml | cut -d' ' -f1)"
+echo "Git commit: $(git rev-parse HEAD)"
+echo "Timestamp: $(date -u '+%Y-%m-%d %H:%M:%S UTC')"
+echo "Actor: ${{ gitea.actor }}"
+echo "=== END METADATA ==="
+```
+
+#### Layer 2: Pre-Cleanup PM2 State Logging
+
+Captures full PM2 process list in JSON format before any modifications.
+
+**Purpose**: Provides forensic evidence of what processes existed before cleanup began.
+
+```bash
+echo "=== PRE-CLEANUP PM2 STATE ==="
+pm2 jlist
+echo "=== END PRE-CLEANUP STATE ==="
+```
+
+#### Layer 3: Process Count Validation (SAFETY ABORT)
+
+The most critical safeguard. Aborts the entire deployment if the filter would delete ALL processes and there are more than 3 processes total.
+
+**Purpose**: Catches filter bugs or unexpected conditions that would result in catastrophic process deletion.
+
+```javascript
+// SAFEGUARD 1: Process count validation
+const totalProcesses = list.length;
+if (targetProcesses.length === totalProcesses && totalProcesses > 3) {
+  console.error('SAFETY ABORT: Filter would delete ALL processes!');
+  console.error(
+    'Total processes: ' + totalProcesses + ', Target processes: ' + targetProcesses.length,
+  );
+  console.error('This indicates a potential filter bug. Aborting cleanup.');
+  process.exit(1);
+}
+```
+
+**Threshold Rationale**: The threshold of 3 allows normal operation when only the 3 expected processes exist (API, Worker, Analytics Worker) while catching anomalies when the server hosts more applications.
+
+#### Layer 4: Explicit Name Verification
+
+Logs the exact name, status, and PM2 ID of each process that will be deleted.
+
+**Purpose**: Provides clear visibility into what the cleanup operation will actually do.
+
+```javascript
+console.log('Found ' + targetProcesses.length + ' PRODUCTION processes to clean:');
+targetProcesses.forEach((p) => {
+  console.log(
+    '  - ' + p.name + ' (status: ' + p.pm2_env.status + ', pm_id: ' + p.pm2_env.pm_id + ')',
+  );
+});
+```
+
+#### Layer 5: Post-Cleanup Verification
+
+After cleanup, logs the state of processes by environment to verify isolation was maintained.
+
+**Purpose**: Immediately identifies if the cleanup affected the wrong environment.
+
+```bash
+echo "=== POST-CLEANUP VERIFICATION ==="
+pm2 jlist | node -e "
+  const list = JSON.parse(require('fs').readFileSync(0, 'utf-8'));
+  const prodProcesses = list.filter(p => p.name && p.name.startsWith('flyer-crawler-') && !p.name.endsWith('-test'));
+  const testProcesses = list.filter(p => p.name && p.name.endsWith('-test'));
+  console.log('Production processes after cleanup: ' + prodProcesses.length);
+  console.log('Test processes (should be untouched): ' + testProcesses.length);
+"
+echo "=== END POST-CLEANUP VERIFICATION ==="
+```

+
+## Testing and Validation
+
+### Test Artifact
+
+A standalone JavaScript test file was created to validate the safeguard logic:
+
+**File**: `tests/qa/test-pm2-safeguard-logic.js`
+
+**Test Categories**:
+
+1. **Normal Operations (should NOT abort)**
+   - 3 errored out of 15 processes
+   - 1 errored out of 10 processes
+   - 0 processes to clean
+   - Fresh server with 3 processes (threshold boundary)
+
+2. **Dangerous Operations (SHOULD abort)**
+   - All 10 processes targeted
+   - All 15 processes targeted
+   - All 4 processes targeted (just above threshold)
+
+3. **Workflow-Specific Filter Tests**
+   - Production filter only matches production processes
+   - Test filter only matches `-test` suffix processes
+   - Filters don't cross-contaminate environments
+
+### Test Results
+
+All 11 scenarios passed:
+
+| Scenario                   | Total | Target | Expected | Result |
+| -------------------------- | ----- | ------ | -------- | ------ |
+| Normal prod cleanup        | 15    | 3      | No abort | PASS   |
+| Normal test cleanup        | 15    | 3      | No abort | PASS   |
+| Single process             | 10    | 1      | No abort | PASS   |
+| No cleanup needed          | 10    | 0      | No abort | PASS   |
+| Fresh server (threshold)   | 3     | 3      | No abort | PASS   |
+| Minimal server             | 2     | 2      | No abort | PASS   |
+| Empty PM2                  | 0     | 0      | No abort | PASS   |
+| Filter bug - 10 processes  | 10    | 10     | ABORT    | PASS   |
+| Filter bug - 15 processes  | 15    | 15     | ABORT    | PASS   |
+| Filter bug - 4 processes   | 4     | 4      | ABORT    | PASS   |
+| Filter bug - 100 processes | 100   | 100    | ABORT    | PASS   |
+
+### YAML Validation

+
+## Lessons Learned
+
+### Technical Lessons
+
+1. **Filter logic alone is not sufficient** - Even correct filters can be bypassed if an older version of the script is executed.
+
+2. **Workflow caching is a real risk** - CI/CD runners may cache workflow files, leading to stale versions being executed.
+
+3. **Defense-in-depth is essential for destructive operations** - Multiple layers of validation catch failures that single-point checks miss.
+
+4. **Visibility enables diagnosis** - Pre/post state logging makes root cause analysis possible.
+
+5. **Automatic abort prevents cascading failures** - The process count validation could have prevented the incident entirely.
+
+### Process Lessons
+
+1. **Shared PM2 daemons are risky** - Multiple applications sharing a PM2 daemon create cross-application dependencies.
+
+2. **Documentation should include failure modes** - CLAUDE.md now explicitly documents what can go wrong and how to respond.
+
+3. **Runbooks save time during incidents** - The incident response runbook provides step-by-step guidance when time is critical.
+
+---
+
+## Future Considerations
+
+### Not Implemented (Potential Future Work)
+
+1. **PM2 Namespacing** - Use PM2's native namespace feature to completely isolate environments.
+
+2. **Separate PM2 Daemons** - Run one PM2 daemon per application to eliminate cross-application risk.
+
+3. **Deployment Locks** - Implement mutex-style locks to prevent concurrent deployments.
+
+4. **Workflow Version Verification** - Add a pre-flight check that compares workflow hash against expected value.
+
+5. **Automated Rollback** - Implement automatic process restoration if safeguards detect a problem.

+# TypeScript Test Error Remediation Project
+
+**Date**: 2026-02-17
+
+**Status**: Completed
+
+**ADR**: [ADR-060](../../adr/0060-typescript-test-error-remediation.md)
+
+## Executive Summary
+
+Systematic remediation of 185 TypeScript errors across the flyer-crawler test suite following API response standardization (ADR-028) and tsoa migration (ADR-059). The project achieved zero TypeScript errors while maintaining test suite integrity.
+
+## Project Metrics
+
+| Metric            | Initial | Final | Change |
+| ----------------- | ------- | ----- | ------ |
+| TypeScript Errors | 185     | 0     | -185   |
+| Tests Passing     | 4,600   | 4,603 | +3     |
+| Tests Failing     | 62      | 59    | -3     |
+| Files Modified    | 0       | 25+   | -      |
+
+## Error Evolution Timeline
+
+```
+Initial Assessment:     185 errors
+After Phase 1-4:        114 errors  (-71)
+After Iteration 2:       67 errors  (-47)
+After Iteration 3:       23 errors  (-44)
+Final:                    0 errors  (-23)
+```
+
+## Root Causes Identified
+
+### 1. SuccessResponse Discriminated Union (48.1%)
+
+ADR-028 introduced `ApiSuccessResponse<T> | ApiErrorResponse` union types. Tests accessing `response.body.data` without type guards triggered TS2339 errors.
+
+**Solution**: Created `asSuccessResponse<T>()` type guard utility.
+
+### 2. Mock Object Type Casting (22.7%)
+
+Vitest mocks return `MockedFunction<T>` types. Passing to functions expecting exact signatures required explicit casting.
+
+**Solution**: Created `asMock<T>()` utility and standardized mock patterns.
+
+### 3. Response Body Property Access (15.1%)
+
+Supertest `response.body` is typed as `unknown`. Direct property access violated strict mode.
+
+**Solution**: Consistent use of `asSuccessResponse()` before accessing `.data`.
+
+### 4. Partial Mock Missing Properties (9.7%)
+
+Factory functions creating partial mocks lacked required properties.
+
+**Solution**: Updated all mock factories to return complete type-safe objects.
+
+### 5. Generic Type Parameter Issues (2.7%)
+
+TypeScript could not infer generics in certain contexts.
+
+**Solution**: Explicit generic parameters on factory calls and assertions.
+
+### 6. Module Import Type Issues (1.6%)
+
+Type mismatches in module mock declarations.
+
+**Solution**: Proper use of `vi.mocked()` and `Mocked<typeof module>` patterns.
+
+## Implementation Strategy
+
+### Phase 1: Foundation (Infrastructure)
+
+Created shared test utilities that enable fixes across all test files:
+
+```typescript
+// src/tests/utils/testHelpers.ts
+export function asSuccessResponse<T>(body: unknown): ApiSuccessResponse<T>;
+export function asErrorResponse(body: unknown): ApiErrorResponse;
+export function asMock<T extends (...args: unknown[]) => unknown>(mock: Mock): T;
+export { createMockLogger, mockLogger } from './mockLogger';
+```
+
+### Phase 2-4: Parallel Execution
+
+Distributed work across multiple parallel tasks:
+
+| Group | Files                                      | Dependencies      |
+| ----- | ------------------------------------------ | ----------------- |
+| A     | Controller tests (auth, user, flyer)       | Phase 1 utilities |
+| B     | Controller tests (recipe, inventory, etc.) | Phase 1 utilities |
+| C     | Service tests                              | None              |
+| D     | Route tests                                | Phase 1 utilities |
+
+### Phase 5: Iterative Refinement
+
+Multiple verification and fix iterations:
+
+1. Run type-check
+2. Analyze remaining errors
+3. Fix errors by file
+4. Re-verify
+5. Repeat until zero errors
+
+## Files Modified

+- `src/tests/utils/mockLogger.ts` - Pino logger mock factory
+- `src/tests/utils/mockFactories.ts` - 60+ entity mock factories

+- `src/services/queueService.server.test.ts`
+
+### Middleware Tests
+
+- `src/middleware/apiVersion.middleware.test.ts`
+
+## Key Patterns Established
+
+### 1. Response Type Narrowing
+
+```typescript
+// Standard pattern for success responses
+const response = await request.get('/api/v1/users/1');
+const body = asSuccessResponse<User>(response.body);
+expect(body.data.id).toBe(1);
+
+// Standard pattern for error responses
+expect(response.status).toBe(400);
+const body = asErrorResponse(response.body);
+expect(body.error.code).toBe('VALIDATION_ERROR');
+```
+
+### 2. Mock Logger Creation
+
+```typescript
+import { createMockLogger } from '../tests/utils/testHelpers';
+
+function createMockRequest(overrides = {}): ExpressRequest {
+  return {
+    body: {},
+    log: createMockLogger(),
+    ...overrides,
+  } as unknown as ExpressRequest;
+}
+```
+
+### 3. Mock Service Casting
+
+```typescript
+import type { Mocked } from 'vitest';
+
+vi.mock('../services/authService');
+import { authService } from '../services/authService';
+
+const mockedAuthService = authService as Mocked<typeof authService>;
+mockedAuthService.login.mockResolvedValue(mockResult);
+```
+
+### 4. Mock Factory Usage
+
+```typescript
+import { createMockUserProfile, createMockFlyer } from '../tests/utils/mockFactories';
+
+const mockUser = createMockUserProfile({ role: 'admin' });
+const mockFlyer = createMockFlyer({ store: { name: 'Test Store' } });
+```
+
+## Lessons Learned
+
+### 1. Infrastructure First
+
+Creating shared utilities before fixing individual files dramatically reduces total effort. The `asSuccessResponse()` utility alone enabled fixes for 89 errors.
+
+### 2. Parallel Execution Efficiency
+
+Organizing work into independent groups allowed parallel execution, reducing wall-clock time from estimated 10 hours to approximately 3.5 hours.
+
+### 3. Iterative Verification
+
+Running type-check after each batch of fixes catches cascading issues early and provides clear progress metrics.
+
+### 4. Complete Mock Factories
+
+Investing in comprehensive mock factories pays dividends across all tests. The 60+ factory functions in `mockFactories.ts` ensure type safety throughout the test suite.
+
+### 5. Consistent Patterns
+
+Establishing and documenting patterns (response narrowing, mock casting, logger creation) ensures consistency and reduces future maintenance burden.
+
+## Verification Results
+
+### Type Check
+
+```bash
+podman exec -it flyer-crawler-dev npm run type-check
+# Exit code: 0
+# Output: No errors
+```
+
+### Test Suite
+
+```bash
+podman exec -it flyer-crawler-dev npm test
+
+# Results:
+# Test Files: 167 passed, 11 failed (178 total)
+# Tests: 4,603 passed, 59 failed (4,662 total)
+# Duration: ~4 minutes
+```
+
+### Pre-existing Failures
+
+The 59 failing tests are pre-existing issues unrelated to this remediation:
+
+- Integration test timing issues
+- Mock isolation in globalSetup
+- Redis/Queue worker interference
+
+## Documentation Updates
+
+1. **ADR-060**: Status updated to "Implemented" with completion metrics
+2. **TESTING.md**: Added TypeScript type safety section
+3. **This document**: Session archive for future reference

+
+## TypeScript Type Safety in Tests (ADR-060)
+
+Tests must be fully type-safe. Common patterns for handling API response types and mock casting are documented below.
+
+### Response Type Narrowing
+
+API responses use discriminated unions (`ApiSuccessResponse<T> | ApiErrorResponse`). Access `.data` only after type narrowing.
+
+**Utility Functions** (`src/tests/utils/testHelpers.ts`):
+
+```typescript
+import { asSuccessResponse, asErrorResponse } from '@/tests/utils/testHelpers';
+
+// Success response access
+const response = await request.get('/api/v1/users/1');
+const body = asSuccessResponse<User>(response.body);
+expect(body.data.id).toBe(1);
+
+// Error response access
+const errorResponse = await request.post('/api/v1/users').send({});
+expect(errorResponse.status).toBe(400);
+const errorBody = asErrorResponse(errorResponse.body);
+expect(errorBody.error.code).toBe('VALIDATION_ERROR');
+```
+
+### Mock Object Type Casting
+
+Use appropriate casting based on type compatibility:
+
+```typescript
+// Level 1: Type assertion for compatible shapes
+const mock = createMockUser() as User;
+
+// Level 2: Unknown bridge for incompatible shapes
+const mock = partialMock as unknown as User;
+
+// Level 3: Partial with required overrides
+const mock: User = { ...createPartialUser(), id: 1, email: 'test@test.com' };
+```
+
+### Mock Function Casting
+
+```typescript
+import { asMock } from '@/tests/utils/testHelpers';
+
+// Cast vi.fn() to specific function type
+const mockFn = vi.fn();
+someService.register(asMock<UserService['create']>(mockFn));
+
+// vi.fn() with explicit type parameters
+const mockFn = vi.fn<[string], Promise<User>>().mockResolvedValue(mockUser);
+
+// vi.mocked() for mocked modules
+vi.mock('@/services/userService');
+const mockedService = vi.mocked(userService);
+mockedService.create.mockResolvedValue(mockUser);
+```
+
+### Mock Logger for Controller Tests
+
+Controllers require a Pino logger on `req.log`. Use the shared mock logger utility:
+
+```typescript
+import { createMockLogger } from '@/tests/utils/testHelpers';
+
+function createMockRequest(overrides = {}): ExpressRequest {
+  return {
+    body: {},
+    cookies: {},
+    log: createMockLogger(),
+    res: { cookie: vi.fn() } as unknown as ExpressResponse,
+    ...overrides,
+  } as unknown as ExpressRequest;
+}
+```
+
+The `createMockLogger()` function returns a complete Pino logger mock with all methods (`info`, `debug`, `error`, `warn`, `fatal`, `trace`, `silent`, `child`) as `vi.fn()` mocks.
+
+### MSW Handler Typing
+
+Ensure MSW handlers return properly typed API responses:
+
+```typescript
+import { ApiSuccessResponse } from '@/types/api';
+import { Flyer } from '@/types/flyer';
+
+http.get('/api/v1/flyers', () => {
+  const response: ApiSuccessResponse<Flyer[]> = {
+    success: true,
+    data: [mockFlyer],
+  };
+  return HttpResponse.json(response);
+});
+```
+
+### Generic Type Parameters
+
+Provide explicit generics when TypeScript cannot infer:
+
+```typescript
+// Factory function generic
+const mock = createMockPaginatedResponse<Flyer>({ data: [mockFlyer] });
+
+// Assertion generic
+expect(result).toEqual<ApiSuccessResponse<User>>({
+  success: true,
+  data: mockUser,
+});
+```
+
+See [ADR-060](../adr/0060-typescript-test-error-remediation.md) for comprehensive patterns and remediation strategies.

+### v0.15.0 Release Contains Fix
+
+Confirmed: v0.15.0 (commit `93ad624`, 2026-02-18) includes the fix commit:
+
+```
+93ad624 ci: Bump version to 0.15.0 for production release [skip ci]
+...
+b6a62a0 be specific about pm2 processes  <-- Fix commit included
+```
+
+### Current Workflow PM2 Commands
+
+**Production Deploy (`deploy-to-prod.yml` line 170)**:
+
+```javascript
+const prodProcesses = [
+  'flyer-crawler-api',
+  'flyer-crawler-worker',
+  'flyer-crawler-analytics-worker',
+];
+list.forEach((p) => {
+  if (
+    (p.pm2_env.status === 'errored' || p.pm2_env.status === 'stopped') &&
+    prodProcesses.includes(p.name)
+  ) {
+    exec('pm2 delete ' + p.pm2_env.pm_id);
+  }
+});
+```
+
+**Test Deploy (`deploy-to-test.yml` line 100)**:
+
+```javascript
+list.forEach((p) => {
+  if (p.name && p.name.endsWith('-test')) {
+    exec('pm2 delete ' + p.pm2_env.pm_id);
+  }
+});
+```
+
+Both implementations have proper name filtering and should NOT affect non-flyer-crawler processes.
+
+---
+
+## Discrepancy Analysis
+
+### Key Mystery
+
+**If the fixes are in place, why did ALL processes get killed?**
+
+### Possible Explanations
+
+#### 1. Workflow Version Mismatch (HIGH PROBABILITY)
+
+**Hypothesis**: Gitea runner cached an older version of the workflow file.
+
+- Gitea Actions may cache workflow definitions
+- The runner might have executed an older version without the fix
+- Need to verify: What version of `deploy-to-prod.yml` actually executed?
+
+**Investigation Required**:
+
+- Check Gitea workflow execution logs for actual script content
+- Verify runner workflow caching behavior
+- Compare executed workflow vs repository version
+
+#### 2. Concurrent Workflow Execution (MEDIUM PROBABILITY)
+
+**Hypothesis**: Another workflow ran simultaneously with destructive PM2 commands.
+
+Workflows with potential issues:
+
+- `manual-db-reset-prod.yml` - Does NOT restart PM2 (schema reset only)
+- `manual-redis-flush-prod.yml` - Does NOT touch PM2
+- Test deployment concurrent with prod deployment
+
+**Investigation Required**:
+
+- Check Gitea Actions history for concurrent workflow runs
+- Review timestamps of all workflow executions on 2026-02-17
+
+#### 3. Manual SSH Command (MEDIUM PROBABILITY)
+
+**Hypothesis**: Someone SSH'd to the server and ran `pm2 stop all` or `pm2 delete all` manually.
+
+**Investigation Required**:
+
+- Check server shell history (if available)
+- Review any maintenance windows or manual interventions
+- Ask team members about manual actions
+
+#### 4. PM2 Internal Issue (LOW PROBABILITY)
+
+**Hypothesis**: PM2 daemon crash or corruption caused all processes to stop.
+
+**Investigation Required**:
+
+- Check PM2 daemon logs on server
+- Look for OOM killer events in system logs
+- Check disk space issues during deployment
+
+#### 5. Script Execution Error (LOW PROBABILITY)
+
+**Hypothesis**: JavaScript parsing error caused the filtering logic to be bypassed.
+
+**Investigation Required**:
+
+- Review workflow execution logs for JavaScript errors
+- Test the inline Node.js scripts locally
+- Check for shell escaping issues
+
+---
+
+## Documentation/Code Gaps Identified
+
+### CLAUDE.md Documentation
+
+The PM2 isolation rules are documented in `CLAUDE.md`, but:
+
+- Documentation uses `pm2 restart all` in the Quick Reference table (for dev container - acceptable)
+- Multiple docs still reference `pm2 restart all` without environment context
+- No incident response runbook for PM2 issues
+
+### Workflow Gaps
+
+1. **No Workflow Audit Trail**: No logging of which exact workflow version executed
+2. **No Pre-deployment Verification**: Workflows don't log PM2 state before modifications
+3. **No Cross-Application Impact Assessment**: No mechanism to detect/warn about other apps
+
+---
+
+## Next Steps for Root Cause Analysis
+
+### Immediate (Priority 1)
+
+1. [ ] Retrieve Gitea Actions execution logs for v0.15.0 deployment
+2. [ ] Extract actual executed workflow content from logs
+3. [ ] Check for concurrent workflow executions on 2026-02-17
+4. [ ] Review server PM2 daemon logs around incident time
+
+### Short-term (Priority 2)
+
+5. [ ] Implement pre-deployment PM2 state logging in workflows
+6. [ ] Add workflow version hash logging for audit trail
+7. [ ] Create incident response runbook for PM2/deployment issues
+
+### Long-term (Priority 3)
+
+8. [ ] Evaluate PM2 namespacing for complete process isolation
+9. [ ] Consider separate PM2 daemon per application
+10. [ ] Implement deployment monitoring/alerting

+
+### Critical Commands
+
+```bash
+# Check PM2 status
+pm2 list
+
+# Check specific process
+pm2 show flyer-crawler-api
+
+# View recent logs
+pm2 logs --lines 50
+
+# Restart specific processes (SAFE)
+pm2 restart flyer-crawler-api flyer-crawler-worker flyer-crawler-analytics-worker
+
+# DO NOT USE (affects ALL apps)
+# pm2 restart all    <-- DANGEROUS
+# pm2 stop all       <-- DANGEROUS

+```
+
+### Severity Classification
+
+| Severity          | Criteria                                      | Response Time       | Example                                         |
+| ----------------- | --------------------------------------------- | ------------------- | ----------------------------------------------- |
+| **P1 - Critical** | Multiple applications down, production impact | Immediate (< 5 min) | All PM2 processes killed                        |
+| **P2 - High**     | Single application down, production impact    | < 15 min            | Flyer Crawler prod down, Stock Alert unaffected |
+| **P3 - Medium**   | Test environment only, no production impact   | < 1 hour            | Test processes killed, production unaffected    |
+
+---
+
+## Detection
+
+### How to Identify a PM2 Incident
+
+**Automated Indicators**:
+
+- Health check failures on `/api/health/ready`
+- Monitoring alerts (UptimeRobot, etc.)
+- Bugsink showing connection errors
+- NGINX returning 502 Bad Gateway
+
+**User-Reported Symptoms**:
+
+- "The site is down"
+- "I can't log in"
+- "Pages are loading slowly then timing out"
+- "I see a 502 error"
+
+**Manual Discovery**:
+
+```bash
+# SSH to server
+ssh gitea-runner@projectium.com
+
+# Check if PM2 is running
+pm2 list
+
+# Expected output shows processes
+# If empty or all errored = incident
+```
+
+### Incident Signature: Process Isolation Violation
+
+When a PM2 incident is caused by process isolation failure, you will see:
+
+```text
+# Expected state (normal):
++-----------------------------------+----+-----+---------+-------+
+| App name                          | id |mode | status  | cpu   |
++-----------------------------------+----+-----+---------+-------+
+| flyer-crawler-api                 | 0  |clust| online  | 0%    |
+| flyer-crawler-worker              | 1  |fork | online  | 0%    |
+| flyer-crawler-analytics-worker    | 2  |fork | online  | 0%    |
+| flyer-crawler-api-test            | 3  |fork | online  | 0%    |
+| flyer-crawler-worker-test         | 4  |fork | online  | 0%    |
+| flyer-crawler-analytics-worker-test| 5 |fork | online  | 0%    |
+| stock-alert-api                   | 6  |fork | online  | 0%    |
++-----------------------------------+----+-----+---------+-------+
+
+# Incident state (isolation violation):
+# All processes missing or errored - not just one app
++-----------------------------------+----+-----+---------+-------+
+| App name                          | id |mode | status  | cpu   |
++-----------------------------------+----+-----+---------+-------+
+# (empty or all processes errored/stopped)
++-----------------------------------+----+-----+---------+-------+
+```
+

+
+## Initial Assessment
+
+### Step 1: Gather Information (2 minutes)
+
+Run these commands and capture output:
+
+```bash
+# 1. Check PM2 status
+pm2 list
+
+# 2. Check PM2 daemon status
+pm2 ping
+
+# 3. Check recent PM2 logs
+pm2 logs --lines 20 --nostream
+
+# 4. Check system status
+systemctl status pm2-gitea-runner --no-pager
+
+# 5. Check disk space
+df -h /
+
+# 6. Check memory
+free -h
+
+# 7. Check recent deployments (in app directory)
+cd /var/www/flyer-crawler.projectium.com
+git log --oneline -5
+```
+
+### Step 2: Determine Scope
+
+| Question                 | Command                                                          | Impact Level                    |
+| ------------------------ | ---------------------------------------------------------------- | ------------------------------- |
+| How many apps affected?  | `pm2 list`                                                       | Count missing/errored processes |
+| Is production down?      | `curl https://flyer-crawler.projectium.com/api/health/ping`      | Yes/No                          |
+| Is test down?            | `curl https://flyer-crawler-test.projectium.com/api/health/ping` | Yes/No                          |
+| Are other apps affected? | `pm2 list \| grep stock-alert`                                   | Yes/No                          |
+
+### Step 3: Classify Severity
+
+```text
+Decision Tree:
+
+Production app(s) down?
+    |
+    +-- YES: Multiple apps affected?
+    |       |
+    |       +-- YES --> P1 CRITICAL (all apps down)
+    |       |
+    |       +-- NO --> P2 HIGH (single app down)
+    |
+    +-- NO: Test environment only?
+            |
+            +-- YES --> P3 MEDIUM
+            |
+            +-- NO --> Investigate further
+```
+
+### Step 4: Document Initial State
+
+Capture this information before making any changes:
+
+```bash
+# Save PM2 state to file
+pm2 jlist > /tmp/pm2-incident-$(date +%Y%m%d-%H%M%S).json
+
+# Save system state
+{
+  echo "=== PM2 List ==="
+  pm2 list
+  echo ""
+  echo "=== Disk Space ==="
+  df -h
+  echo ""
+  echo "=== Memory ==="
+  free -h
+  echo ""
+  echo "=== Recent Git Commits ==="
+  cd /var/www/flyer-crawler.projectium.com && git log --oneline -5
+} > /tmp/incident-state-$(date +%Y%m%d-%H%M%S).txt
+```
+
+---
+
+## Immediate Response
+
+### Priority 1: Stop Ongoing Deployments
+
+If a deployment is currently running:
+
+1. Check Gitea Actions for running workflows
+2. Cancel any in-progress deployment workflows
+3. Do NOT start new deployments until incident resolved
+
+### Priority 2: Assess Which Processes Are Down
+
+```bash
+# Get list of processes and their status
+pm2 list
+
+# Check which processes exist but are errored/stopped
+pm2 jlist | jq '.[] | {name, status: .pm2_env.status}'
+```
+
+### Priority 3: Establish Order of Restoration
+
+Restore in this order (production first, critical path first):
+
+| Priority | Process                               | Rationale                            |
+| -------- | ------------------------------------- | ------------------------------------ |
+| 1        | `flyer-crawler-api`                   | Production API - highest user impact |
+| 2        | `flyer-crawler-worker`                | Production background jobs           |
+| 3        | `flyer-crawler-analytics-worker`      | Production analytics                 |
+| 4        | `stock-alert-*`                       | Other production apps                |
+| 5        | `flyer-crawler-api-test`              | Test environment                     |
+| 6        | `flyer-crawler-worker-test`           | Test background jobs                 |
+| 7        | `flyer-crawler-analytics-worker-test` | Test analytics                       |
+
+---
+
+## Process Restoration
+
+### Scenario A: Flyer Crawler Production Processes Missing
+
+```bash
+# Navigate to production directory
+cd /var/www/flyer-crawler.projectium.com
+
+# Start production processes
+pm2 start ecosystem.config.cjs
+
+# Verify processes started
+pm2 list
+
+# Check health endpoint
+curl -s http://localhost:3001/api/health/ready | jq .
+```
+
+### Scenario B: Flyer Crawler Test Processes Missing
+
+```bash
+# Navigate to test directory
+cd /var/www/flyer-crawler-test.projectium.com
+
+# Start test processes
+pm2 start ecosystem-test.config.cjs
+
+# Verify processes started
+pm2 list
+
+# Check health endpoint
+curl -s http://localhost:3002/api/health/ready | jq .
+```
+
+### Scenario C: Stock Alert Processes Missing
+
+```bash
+# Navigate to stock-alert directory
+cd /var/www/stock-alert.projectium.com
+
+# Start processes (adjust config file name as needed)
+pm2 start ecosystem.config.cjs
+
+# Verify processes started
+pm2 list
+```
+
+### Scenario D: All Processes Missing
+
+Execute restoration in priority order:
+
+```bash
+# 1. Flyer Crawler Production (highest priority)
+cd /var/www/flyer-crawler.projectium.com
+pm2 start ecosystem.config.cjs
+
+# Verify production is healthy before continuing
+curl -s http://localhost:3001/api/health/ready | jq '.data.status'
+# Should return "healthy"
+
+# 2. Stock Alert Production
+cd /var/www/stock-alert.projectium.com
+pm2 start ecosystem.config.cjs
+
+# 3. Flyer Crawler Test (lower priority)
+cd /var/www/flyer-crawler-test.projectium.com
+pm2 start ecosystem-test.config.cjs
+
+# 4. Save PM2 process list
+pm2 save
+
+# 5. Final verification
+pm2 list
+```
+
+### Health Check Verification
+
+After restoration, verify each application:
+
+**Flyer Crawler Production**:
+
+```bash
+# API health
+curl -s https://flyer-crawler.projectium.com/api/health/ready | jq '.data.status'
+# Expected: "healthy"
+
+# Check all services
+curl -s https://flyer-crawler.projectium.com/api/health/ready | jq '.data.services'
+```
+
+**Flyer Crawler Test**:
+
+```bash
+curl -s https://flyer-crawler-test.projectium.com/api/health/ready | jq '.data.status'
+```
+
+**Stock Alert**:
+
+```bash
+# Adjust URL as appropriate for stock-alert
+curl -s https://stock-alert.projectium.com/api/health/ready | jq '.data.status'
+```
+
+### Verification Checklist
+
+After restoration, confirm:
+
+- [ ] `pm2 list` shows all expected processes as `online`
+- [ ] Production health check returns `healthy`
+- [ ] Test health check returns `healthy` (if applicable)
+- [ ] No processes showing high restart count
+- [ ] No processes showing `errored` or `stopped` status
+- [ ] PM2 process list saved: `pm2 save`
+
+---
+
+## Root Cause Investigation
+
+### Step 1: Check Workflow Execution Logs
+
+```bash
+# Find recent Gitea Actions runs
+# (Access via Gitea web UI: Repository > Actions > Recent Runs)
+
+# Look for these workflows:
+# - deploy-to-prod.yml
+# - deploy-to-test.yml
+# - manual-deploy-major.yml
+# - manual-db-restore.yml
+```
+
+### Step 2: Check PM2 Daemon Logs
+
+```bash
+# PM2 daemon logs
+cat ~/.pm2/pm2.log | tail -100
+
+# PM2 process-specific logs
+ls -la ~/.pm2/logs/
+
+# Recent API logs
+tail -100 ~/.pm2/logs/flyer-crawler-api-out.log
+tail -100 ~/.pm2/logs/flyer-crawler-api-error.log
+```
+
+### Step 3: Check System Logs
+
+```bash
+# System journal for PM2 service
+journalctl -u pm2-gitea-runner -n 100 --no-pager
+
+# Kernel messages (OOM killer, etc.)
+journalctl -k -n 50 --no-pager | grep -i "killed\|oom\|memory"
+
+# Authentication logs (unauthorized access)
+tail -50 /var/log/auth.log
+```
+
+### Step 4: Git History Analysis
+
+```bash
+# Recent commits to deployment workflows
+cd /var/www/flyer-crawler.projectium.com
+git log --oneline -20 -- .gitea/workflows/
+
+# Check what changed in PM2 configs
+git log --oneline -10 -- ecosystem.config.cjs ecosystem-test.config.cjs
+
+# Diff against last known good state
+git diff <last-good-commit> -- .gitea/workflows/ ecosystem*.cjs
+```
+
+### Step 5: Timing Correlation
+
+Create a timeline:
+
+```text
+| Time (UTC) | Event | Source |
+|------------|-------|--------|
+| XX:XX | Last successful health check | Monitoring |
+| XX:XX | Deployment workflow started | Gitea Actions |
+| XX:XX | First failed health check | Monitoring |
+| XX:XX | Incident detected | User report / Alert |
+| XX:XX | Investigation started | On-call |
+```
+
+### Common Root Causes
+
+| Root Cause                   | Evidence                               | Prevention                   |
+| ---------------------------- | -------------------------------------- | ---------------------------- |
+| `pm2 stop all` in workflow   | Workflow logs show "all" command       | Use explicit process names   |
+| `pm2 delete all` in workflow | Empty PM2 list after deploy            | Use whitelist-based deletion |
+| OOM killer                   | `journalctl -k` shows "Killed process" | Increase memory limits       |
+| Disk space exhaustion        | `df -h` shows 100%                     | Log rotation, cleanup        |
+| Manual intervention          | Shell history shows pm2 commands       | Document all manual actions  |
+| Concurrent deployments       | Multiple workflows at same time        | Implement deployment locks   |
+| Workflow caching issue       | Old workflow version executed          | Force workflow refresh       |

+## Prevention Measures
+
+### Pre-Deployment Checklist
+
+Before triggering any deployment:
+
+- [ ] Review workflow file for PM2 commands
+- [ ] Confirm no `pm2 stop all`, `pm2 delete all`, or `pm2 restart all`
+- [ ] Verify process names are explicitly listed
+- [ ] Check for concurrent deployment risks
+- [ ] Confirm recent workflow changes were reviewed
+
+### Workflow Review Checklist
+
+When reviewing deployment workflow changes:
+
+- [ ] All PM2 `stop` commands use explicit process names
+- [ ] All PM2 `delete` commands filter by process name pattern
+- [ ] All PM2 `restart` commands use explicit process names
+- [ ] Test deployments filter by `-test` suffix
+- [ ] Production deployments use whitelist array
+
+**Safe Patterns**:
+
+```javascript
+// SAFE: Explicit process names (production)
+const prodProcesses = [
+  'flyer-crawler-api',
+  'flyer-crawler-worker',
+  'flyer-crawler-analytics-worker',
+];
+list.forEach((p) => {
+  if (
+    (p.pm2_env.status === 'errored' || p.pm2_env.status === 'stopped') &&
+    prodProcesses.includes(p.name)
+  ) {
+    exec('pm2 delete ' + p.pm2_env.pm_id);
+  }
+});
+
+// SAFE: Pattern-based filtering (test)
+list.forEach((p) => {
+  if (p.name && p.name.endsWith('-test')) {
+    exec('pm2 delete ' + p.pm2_env.pm_id);
+  }
+});
+```
+
+**Dangerous Patterns** (NEVER USE):
+
+```bash
+# DANGEROUS - affects ALL applications
+pm2 stop all
+pm2 delete all
+pm2 restart all
+
+# DANGEROUS - no name filtering
+pm2 delete $(pm2 jlist | jq -r '.[] | select(.pm2_env.status == "errored") | .pm_id')
+```
+
+### PM2 Configuration Validation
+
+Before deploying PM2 config changes:
+
+```bash
+# Test configuration locally
+cd /var/www/flyer-crawler.projectium.com
+node -e "console.log(JSON.stringify(require('./ecosystem.config.cjs'), null, 2))"
+
+# Verify process names
+node -e "require('./ecosystem.config.cjs').apps.forEach(a => console.log(a.name))"
+
+# Expected output should match documented process names
+```
+
+### Deployment Monitoring
+
+After every deployment:
+
+```bash
+# Immediate verification
+pm2 list
+
+# Check no unexpected processes were affected
+pm2 list | grep -v flyer-crawler
+# Should still show other apps (e.g., stock-alert)
+
+# Health check
+curl -s https://flyer-crawler.projectium.com/api/health/ready | jq '.data.status'
+```

+
+### Lessons Learned Format
+
+Use "5 Whys" technique:
+
+```text
+Problem: All PM2 processes were killed during deployment
+
+Why 1: The deployment workflow ran `pm2 delete all`
+Why 2: The workflow used an outdated version of the script
+Why 3: Gitea runner cached the old workflow file
+Why 4: No mechanism to verify workflow version before execution
+Why 5: Workflow versioning and audit trail not implemented
+
+Root Cause: Lack of workflow versioning and execution verification
+
+Preventive Measure: Implement workflow hash logging and pre-execution verification
+```
+
+### Action Items Tracking
+
+Create Gitea issues for each action item:
+
+```bash
+# Example using Gitea CLI or API
+gh issue create --title "Implement PM2 state logging in deployment workflows" \
+  --body "Related to incident YYYY-MM-DD. Add pre-deployment PM2 state capture." \
+  --label "incident-follow-up,priority:high"
+```
+
+Track action items in a central location:
+
+| Issue # | Action                           | Owner  | Due    | Status |
+| ------- | -------------------------------- | ------ | ------ | ------ |

+## Appendix: PM2 Command Reference
+
+### Safe Commands
+
+```bash
+# Status and monitoring
+pm2 list
+pm2 show <process-name>
+pm2 monit
+pm2 logs <process-name>
+
+# Restart specific processes
+pm2 restart flyer-crawler-api
+pm2 restart flyer-crawler-api flyer-crawler-worker flyer-crawler-analytics-worker
+
+# Reload (zero-downtime, cluster mode only)
+pm2 reload flyer-crawler-api
+
+# Start from config
+pm2 start ecosystem.config.cjs
+pm2 start ecosystem.config.cjs --only flyer-crawler-api
+```
+
+### Dangerous Commands (Use With Caution)
+
+```bash
+# CAUTION: These affect ALL processes
+pm2 stop all        # Stops every PM2 process
+pm2 restart all     # Restarts every PM2 process
+pm2 delete all      # Removes every PM2 process
+
+# CAUTION: Modifies saved process list
+pm2 save            # Overwrites saved process list
+pm2 resurrect       # Restores from saved list
+
+# CAUTION: Affects PM2 daemon
+pm2 kill            # Kills PM2 daemon and all processes
+pm2 update          # Updates PM2 in place (may cause brief outage)
+```
