2. Execute a leakage-safe and reproducible workflow for this skill domain.
3. Validate outputs with diagnostics, edge-case checks, and documented caveats.

## Output format

- A concise plan of action
- Executable code or commands
- Validation summary with assumptions and risks

## Examples

### Example 1 - baseline workflow

**Input:** User asks for help in data-validation-and-schema-contracts.
