---

## Issues Found and Fixed

### ⚠️ Major Issues (FIXED)

#### MAJOR ISSUE #1: Missing Explicit Review Resolution Note
**Description:** Story 3-3 has completed Senior Developer Review, but Story 3.4 didn't explicitly state that all review items were resolved.

**Location:** Dev Notes → Learnings from Previous Story → Review Findings

**Impact:** Could miss epic-wide concerns if previous story had unresolved items. Checklist requires explicit callout of unresolved review items.

**Evidence:** 
- Previous story review section exists (3-3 lines 456-641)
- All action items completed (3-3 line 599-605)
- Current story referenced review findings but didn't explicitly state resolution

**Fix Applied:** Added line 115:
```markdown
- **All review action items from Story 3.3 completed** - No unresolved items carry forward to Story 3.4
```

**Verification:** Line 115 now explicitly confirms no unresolved items, satisfying checklist requirement for "unresolved review items alert"

---

#### MAJOR ISSUE #2: Inconsistent Parameter Naming in Task 7
**Description:** Task 7 said "Validate MCP tool schema parameters match PurgeQueueRequest model" but this was ambiguous about how MCP tool parameters map to Pydantic model fields.

**Location:** Tasks section, Task 7, line 71

**Impact:** Could cause confusion during implementation about parameter mapping between MCP tool and Pydantic schema.

**Evidence:** 
- Original wording: "Validate MCP tool schema parameters match PurgeQueueRequest model"
- RabbitMQ operations use path parameters in HTTP API but body/field parameters in Pydantic models
- Similar operations use parameter mapping pattern (see Story 3-3)

**Fix Applied:** Changed line 71 to:
```markdown
- [ ] Validate MCP tool accepts vhost and name parameters that map to PurgeQueueRequest model fields
```

**Verification:** Now explicitly states that MCP tool parameters map to model fields, clarifying the relationship

---

### ℹ️ Minor Issues (FIXED)

#### MINOR ISSUE #1: Test Scenario Organization Mismatch
**Description:** Test scenarios section listed scenarios by type but didn't align with schema vs operation test structure used in previous stories.

**Location:** Testing Standards → Unit Test Scenarios (lines 258-283)

**Impact:** Minor - could lead to slightly different test organization than Story 3.3 pattern.

**Evidence:**
- Story 3-3 achieved 40 tests (16 schema + 24 operation)
- Original test scenarios didn't clearly separate schema vs operation tests
- Could lead to developer creating tests in different structure

**Fix Applied:** Reorganized test scenarios with clear categories:
```markdown
**Unit Test Scenarios (Target: ~20-24 tests similar to Story 3.3):**
1. **Schema Validation Tests (~8 tests):**
2. **Successful Purge Tests (~5 scenarios):**
3. **Error Handling Tests (~4 scenarios):**
4. **Response Parsing Tests (~3 scenarios):**
5. **Logging Tests (~5 scenarios):**
```

**Verification:** Now aligns with Story 3-3 pattern (schema tests + operation tests) with target counts
