# Phase 3: Crash Recovery Test Execution Log

**Start Date:** 2026-08-03 22:35 KST  
**Status:** 🚀 **IN PROGRESS**  
**Parallel with:** Phase 1 (Job 893 running)

---

## 🧪 **Test Scenario 1: Outbox Message Loss**

### Setup
- **Objective:** Verify ShadowRunCompletedConsumer recovery from lost outbox messages
- **Method:** Simulate message drop in Outbox table
- **Environment:** Host running, Job 893 active

### Execution
```
Step 1: Trigger message loss scenario
  □ Identify current outbox message
  □ Simulate deletion/loss
  □ Verify detection
  Status: ⏳ QUEUED

Step 2: Monitor recovery
  □ Watch ShadowRunCompletedConsumer logs
  □ Check retry mechanism activation
  □ Verify message re-processing
  Status: ⏳ QUEUED

Step 3: Validation
  □ No state corruption observed
  □ Message eventually processed
  □ Logs contain recovery trace
  Status: ⏳ QUEUED
```

### Result
```
Status: ⏳ PENDING
Evidence: [logs will be captured]
Outcome: [ ] PASS  [ ] FAIL
```

## 🧪 **Test Scenario 2: PostgreSQL Connection Drop**

### Setup
- **Objective:** Verify graceful recovery from database disconnection
- **Method:** Simulate connection timeout/reset
- **Environment:** SSH tunnel maintained

### Execution
```
Step 1: Trigger connection drop
  □ Monitor connection pool
  □ Simulate network disconnect
  □ Trigger reconnection
  Status: ⏳ QUEUED

Step 2: Monitor recovery
  □ Watch connection retry logic
  □ Check reconnection attempt
  □ Verify query resumption
  Status: ⏳ QUEUED

Step 3: Validation
  □ No data loss
  □ No duplicate processing
  □ Transaction consistency maintained
  Status: ⏳ QUEUED
```

### Result
```
Status: ⏳ PENDING
Evidence: [logs will be captured]
Outcome: [ ] PASS  [ ] FAIL
```

## 🧪 **Test Scenario 3: Hangfire Lock Timeout**

### Setup
- **Objective:** Verify lock timeout recovery (DEBT-015)
- **Method:** Simulate distributed lock contention
- **Environment:** Multiple worker simulation

### Execution
```
Step 1: Trigger lock timeout
  □ Create lock contention
  □ Trigger timeout condition
  □ Monitor fallback activation
  Status: ⏳ QUEUED

Step 2: Monitor recovery
  □ Verify DEBT-015 fallback mechanism
  □ Check job continues without blocking
  □ Verify other workers unaffected
  Status: ⏳ QUEUED

Step 3: Validation
  □ No deadlock observed
  □ Graceful degradation
  □ Recovery automatic
  Status: ⏳ QUEUED
```

### Result
```
Status: ⏳ PENDING
Evidence: [logs will be captured]
Outcome: [ ] PASS  [ ] FAIL
```

## 🧪 **Test Scenario 4: Inbox Message Processing Failure**

### Setup
- **Objective:** Verify consumer resilience to processing failures
- **Method:** Simulate deserialization/processing error
- **Environment:** ApprovalQueueConsumer or AuditLogConsumer

### Execution
```
Step 1: Trigger processing failure
  □ Inject malformed message
  □ Trigger deserialization error
  □ Monitor error handling
  Status: ⏳ QUEUED

Step 2: Monitor recovery
  □ Verify error caught by consumer
  □ Check DLQ (Dead Letter Queue) movement
  □ Monitor alert generation
  Status: ⏳ QUEUED

Step 3: Validation
  □ No data loss
  □ Failure logged with context
  □ Main pipeline unaffected
  Status: ⏳ QUEUED
```

### Result
```
Status: ⏳ PENDING
Evidence: [logs will be captured]
Outcome: [ ] PASS  [ ] FAIL
```
