# Example Validation Assessment - WP-035 Cycle 1.4

**Analysis Date**: December 9, 2025
**Scope**: Example functionality and documentation assessment

---

## Examples Missing READMEs (Critical Priority)

### `examples/migrations/`
- **Content**: Single SQL file (`datetime_utc_normalization.sql`)
- **Status**: No README, no Python code
- **Issue**: Pure SQL migration example with no documentation
- **Recommendation**: Create README explaining the migration pattern and when to use it

### `examples/observability/`
- **Content**: Docker Compose and configuration files for Loki/Grafana
- **Status**: No README, configuration-only
- **Issue**: Infrastructure setup example with no usage instructions
- **Recommendation**: Create README with setup instructions and integration guide

### `examples/query_patterns/`
- **Content**: Two Python files demonstrating query registration patterns
- **Status**: No README, functional code
- **Issue**: Good example code but no documentation for users
- **Recommendation**: Create comprehensive README explaining the three query patterns

---

## Examples Needing README Improvements

### `examples/todo_xs/`
- **Current**: Has README in `db/00_schema/` subdirectory
- **Issue**: README not at root level where users expect it
- **Recommendation**: Move README to root and enhance with usage examples

---

## Functional Examples Assessment

### Working Examples ✅
- `examples/query_patterns/app.py` - Functional, demonstrates query patterns
- `examples/query_patterns/blog_pattern.py` - Functional, clean blog example
- `examples/todo_xs/db/00_schema/schema.sql` - SQL schema (no Python code to test)

### Examples Needing Python Code
- `examples/migrations/` - Only SQL, needs Python example
- `examples/observability/` - Only config, needs Python integration example

---

## Documentation Gaps Identified

### Missing Setup Instructions
Most examples lack:
- Prerequisites/dependencies
- Database setup commands
- Environment configuration
- Running instructions

### Missing Usage Examples
Examples need:
- GraphQL query examples
- Sample API calls
- Integration patterns
- Error handling examples

### Missing Context
Examples should explain:
- When to use this pattern
- Performance characteristics
- Scaling considerations
- Alternative approaches

---

## Implementation Plan

### Phase 1: Create Missing READMEs (Week 1)
1. **migrations/README.md**
   - Explain datetime UTC normalization pattern
   - Show when and how to apply this migration
   - Include SQL examples and testing

2. **observability/README.md**
   - Explain Loki/Grafana integration
   - Provide setup and configuration instructions
   - Show how to integrate with FraiseQL apps

3. **query_patterns/README.md**
   - Explain the three query registration patterns
   - Show code examples for each pattern
   - Compare pros/cons of each approach

### Phase 2: Move and Enhance Existing READMEs (Week 2)
1. **todo_xs/README.md**
   - Move from `db/00_schema/README.md` to root
   - Add Python usage examples
   - Include GraphQL queries

### Phase 3: Add Python Code to Config-Only Examples (Week 3)
1. **migrations/app.py**
   - Create Python example showing datetime handling
   - Demonstrate before/after migration behavior

2. **observability/app.py**
   - Create Python example with logging/metrics
   - Show Loki integration

### Phase 4: Quality Assurance (Week 4)
1. **Test all examples**
   - Verify Python examples run
   - Test GraphQL queries
   - Check documentation accuracy

2. **Standardize format**
   - Apply consistent README template
   - Add missing sections (prerequisites, setup, usage)
   - Include performance notes where relevant

## Success Criteria

- [ ] All examples have root-level README files
- [ ] All READMEs follow consistent format with required sections
- [ ] Examples include working Python code where applicable
- [ ] GraphQL usage examples provided for all examples
- [ ] Setup instructions are complete and accurate
- [ ] Performance characteristics documented where relevant
