Evidence: Lines 13-15 contain all three user story fields properly formatted.

✓ **Acceptance criteria list matches story draft exactly (no invention)**  
Evidence: Lines 29-37 contain 7 acceptance criteria wrapped in CDATA section. All criteria match the story draft at docs-bmad/sprint-artifacts/3-8-list-bindings-operation.md (lines 13-19). Fixed HTML entity escaping issue.

✓ **Tasks/subtasks captured as task list**  
Evidence: Lines 16-26 list 9 tasks with AC mappings (Task 1 through Task 9). Each task references specific acceptance criteria numbers.

- 1x epic-3-topology-operations.md (Epic overview)
- 1x operations-3.13.json (MCP tool registry)

✓ **Relevant code references included with reason and line hints**  
Evidence: Lines 98-139 include 6 code artifacts with paths, symbols, line ranges, and detailed reasons:
- topology.py operations (lines 48-700)
- topology.py schemas (lines 29-500)
- http_client.py (lines 1-200)
- test_topology.py unit tests (lines 1-1254)
- test_binding_operations.py integration tests (lines 1-500)
- bindings.py MCP tool (lines 1-300)

✓ **Interfaces/API contracts extracted if applicable**  
Evidence: Lines 180-187 define 6 interfaces:
- 3x RabbitMQ Management API endpoints (GET /api/bindings, alternative endpoints)
- HTTPClientManager.request interface
- ListBindingsOperation.execute interface
- MCP Tool bindings.list interface via call-id

✓ **Constraints include applicable dev rules and patterns**  
Evidence: Lines 165-179 document 15 constraints including API spec version, URL encoding, service location, schema location, client-side filtering strategy, caching policy, operation safety, binding types, routing patterns, properties key, performance target, HTTP client configuration, and correlation_id tracking.

✓ **Dependencies detected from manifests and frameworks**  
Evidence: Lines 141-151 list 8 Python packages with versions and reasons:
- httpx >=0.27 (Async HTTP client)
- pydantic >=2.0 (Schema validation)
- structlog >=24.1 (Structured logging)
- pytest >=8.0 (Testing framework)
- pytest-asyncio >=0.23 (Async test support)
- pytest-cov >=4.1 (Coverage measurement)
- testcontainers >=4.0 (RabbitMQ testcontainers)

✓ **Testing standards and locations populated**  
Evidence: Lines 179-203 include:
- Testing standards paragraph (pytest, 80% coverage, mocking strategy, testcontainers, patterns from Stories 3.1 and 3.5)
- 3 test locations (schema tests, unit tests, integration tests)
- 14 test ideas covering all 7 acceptance criteria plus error handling, logging verification, and integration scenarios

✓ **XML structure follows story-context template format**  
Evidence: Document follows template structure with all required sections: metadata, story, acceptanceCriteria, artifacts (docs, code, dependencies), constraints, interfaces, tests (standards, locations, ideas).

## Issues Fixed

### Issue #1: HTML Entity Escaping in Acceptance Criteria ✅ FIXED
**Location:** Line 34 (originally line 34)  
**Problem:** Acceptance criteria #5 used escaped HTML entity `&lt;` instead of `<` for "200ms" performance target  
**Fix Applied:** Wrapped entire acceptanceCriteria block in CDATA section (lines 29-37) to preserve raw text with `<` symbol  
**Impact:** High - Improves readability and prevents XML parsing confusion

### Issue #2: HTML Entity Escaping in Constraints Section ✅ FIXED
**Location:** Line 176 (wrapped in CDATA lines 165-179)  
**Problem:** Performance constraint and other constraints with special characters needed CDATA protection  
**Fix Applied:** Wrapped entire constraints block in CDATA section to preserve raw text with `<` symbol and other special characters  
**Impact:** High - Ensures XML validity while maintaining readability

### Issue #3: HTML Entity Escaping in Performance Doc Snippet ✅ FIXED
**Location:** Line 57  
**Problem:** Doc snippet for performance used raw `<` which breaks XML in snippet element  
**Fix Applied:** Used proper XML entity `&lt;` in snippet: "List operations target &lt;200ms p95 for up to 1000 resources"  
**Impact:** High - Maintains XML validity in doc snippets

### Issue #4: Missing Epic 3 Main File Reference ✅ FIXED
**Location:** Lines 95-100 (newly added)  
**Problem:** Epic overview file (epic-3-topology-operations.md) was not referenced in docs section  
**Fix Applied:** Added doc reference:
```xml
<doc>
  <path>docs-bmad/epics/epic-3-topology-operations.md</path>
  <title>Epic 3: Topology Operations</title>
  <section>Epic Overview - Story 3.8</section>
  <snippet>Story 3.8 List Bindings Operation: List all exchange-to-queue and exchange-to-exchange bindings...</snippet>
</doc>
```
**Impact:** Medium - Provides important epic-level context for story

### Issue #5: Missing MCP Operations Registry Reference ✅ FIXED
**Location:** Lines 101-107 (newly added)  
**Problem:** operations-3.13.json registry mentioned in story Task 8 (line 94) but not documented  
**Fix Applied:** Added doc reference:
```xml
<doc>
  <path>data/operations-3.13.json</path>
  <title>RabbitMQ 3.13 Operations Registry</title>
  <section>MCP Tool Registry - bindings.list</section>
  <snippet>Operation registry derived from RabbitMQ Management API OpenAPI spec v3.13...</snippet>
</doc>
```
**Impact:** Medium - Clarifies MCP tool registration mechanism referenced in tasks

## Recommendations

### ✅ All Critical Recommendations Implemented

1. ✅ **Use CDATA for Complex Text**: Implemented - Acceptance criteria (lines 29-37) and constraints (lines 165-179) wrapped in CDATA to handle special characters cleanly
2. ✅ **XML Entity Encoding in Snippets**: Implemented - Doc snippets use proper `&lt;` entities where CDATA is not appropriate
3. ✅ **Complete Documentation Coverage**: Implemented - Added missing epic overview and operations registry references
4. ✅ **XML Validation**: Document passes xmllint validation without errors
5. ✅ **Comprehensive Context**: Now includes 11 doc references (up from 9), covering all aspects mentioned in story tasks

## Validation Summary

**VALIDATION PASSED** ✅

The story context file now meets ALL checklist requirements:
- 10/10 items passed
- 5 issues identified and fixed
- 3 recommendations fully implemented
- Document is ready for development handoff

### Changes Made
1. Wrapped acceptance criteria in CDATA section for clean `<` symbol handling (lines 29-37)
2. Wrapped constraints section in CDATA for special character handling (lines 165-179)
3. Used proper XML entity `&lt;` in doc snippet (line 57)
4. Added Epic 3 overview doc reference (epic-3-topology-operations.md, lines 95-100)
5. Added MCP operations registry doc reference (data/operations-3.13.json, lines 101-107)
6. **XML Validation:** Document passes xmllint validation ✅

### Quality Metrics
- Documentation completeness: 11 docs (target: 5-15) ✅
- Code references: 6 artifacts with full details ✅
- Test coverage plan: 14 test ideas covering all ACs ✅
- Interface definitions: 6 interfaces documented ✅
