**Current Status:** ✓ PASS - 8 documentation artifacts provided

**Added Artifacts:**
1. ✅ docs-bmad/prd/functional-requirements.md - FR-006, FR-008, FR-009 context

5. ✅ docs-bmad/architecture/deployment-architecture.md - Configuration management, TTL tuning

**Total:** 8 documentation artifacts (within 5-15 range) ✅

---

### ✅ Fix #2: Code Reference Line Hints (CRITICAL - RESOLVED)
**Previous Status:** ✗ FAIL - All artifacts said "All" with no specific line ranges  
**Current Status:** ✓ PASS - All artifacts have precise line ranges

**Updated Artifacts:**

1. **topology.py** ✅
   - **Before:** "All classes"
   - **After:** "53-381 (ListQueues), 382-682 (CreateQueue), 683-954 (DeleteQueue), 955-1124 (PurgeQueue), 1125-1365 (ListExchanges), 1366-1690 (CreateExchange), 1691-1934 (DeleteExchange), 1935-2193 (ListBindings), 2194-2780 (CreateBinding), 2781-3071 (DeleteBinding)"
   - Covers all 10 operation classes with exact line ranges

2. **http_client.py** ✅
   - **Before:** "All"
   - **After:** "78-809 (class definition and all methods)"
   - HTTPClientManager class fully scoped

3. **connection/exceptions.py** ✅
   - **Before:** "All"
   - **After:** "25-38 (ConnectionError base class and VHostNotFoundError which already exists)"
   - Pinpoints exact exception hierarchy and existing VHostNotFoundError at line 37-38

4. **schemas/topology.py** ✅
   - **Before:** "All"
   - **After:** "29-110 (QueueDetails), 111-258 (CreateQueueRequest), 259-323 (DeleteQueueRequest), 324-402 (PurgeQueueRequest), 403-481 (ExchangeInfo), 540-687 (CreateExchangeRequest), 688-764 (DeleteExchangeRequest), 787-889 (BindingInfo), 966-1099 (CreateBindingRequest), 1100-1240 (DeleteBindingRequest)"
   - All 10 Pydantic schemas with precise line ranges

**Removed Artifact:**
- ❌ src/utils/errors.py - Removed because VHostNotFoundError already exists in connection/exceptions.py (not needed)

---

### ✅ Fix #3: Interface Specifications (PARTIAL - NOW PASS)
**Previous Status:** ⚠ PARTIAL - VhostNotFoundError marked as needing creation but already exists  
**Current Status:** ✓ PASS - All interfaces accurate and complete

**Corrections:**

1. **VHostNotFoundError Interface** ✅
   - **Before:** "class VhostNotFoundError(RabbitMQError)" in "connection/exceptions.py or src/utils/errors.py"
   - **After:** "class VHostNotFoundError(ConnectionError)" in "connection/exceptions.py (line 37-38, already exists)"
   - Added note: "Implementation should enhance error message to include list of available vhosts"

2. **Added invalidate_cache Interface** ✅
   - **New:** VhostValidator.invalidate_cache() -> None
   - Addresses AC #6 requirement for cache refresh on vhost create/delete
   - Signature: `def invalidate_cache() -> None`

3. **Enhanced validate_vhost decorator description** ✅
   - Added: "Handles both async and sync functions"

4. **Enhanced GET /api/vhosts description** ✅
   - Added response format example: `[{"name": "/", "description": "Default virtual host", ...}, ...]`

**Total:** 5 interfaces (was 4, added cache invalidation) ✅

---

### ✅ Fix #4: Testing Standards Expansion (MEDIUM - NOW PASS)
**Previous Status:** ✗ FAIL - Missing test patterns, fixtures, integration setup  
**Current Status:** ✓ PASS - Comprehensive testing guidance provided

**Enhancements:**

1. **Existing Test Pattern References** ✅
   - Added: tests/unit/rabbitmq_mcp_connection/test_http_client_pooling.py - HTTPClientManager mocking patterns
   - Added: tests/unit/rabbitmq_mcp_connection/schemas/test_topology.py - Pydantic validation patterns
   - Added: tests/conftest.py - rabbitmq_server fixture for integration tests

2. **Test Fixtures** ✅
   - Standard vhosts: "/" (default), "/test", "/staging"
   - Mock response format: `[{"name": "/"}, {"name": "/test"}, {"name": "/staging"}]`
   - Correlation ID fixtures from conftest.py

3. **Performance Metrics** ✅
   - p50 (median): <20ms expected
   - p95: <50ms required (AC #3)
   - p99: <75ms acceptable
   - Cache hit: <1ms expected

4. **Mocking Patterns** ✅
   - pytest-mock: `mocker.patch()` for HTTPClientManager.request()
   - Time mocking: `mocker.patch("time.time")` for TTL testing
   - Concurrency: `asyncio.gather()` pattern
   - Spy usage: `mocker.spy()` for invocation order verification

5. **Integration Test Environment** ✅
   - RabbitMQ 3.12+ with management plugin enabled
   - Use testcontainers from conftest.py
   - HTTPClientManager audit log verification

6. **Test Ideas Enhanced** ✅
   - All 7 test ideas now include specific implementation details
   - References to mocking patterns and test file locations
   - Concrete assertion examples
