Guardrails
- Fixture updates map to intentional behavior changes.
- Do not update fixtures only to make tests pass.
- MCP, CLI, and JSON fixture updates stay aligned.
- JSON fixtures preserve stable structured output envelopes.
- Volatile values are normalized in code, not patched ad hoc in fixtures.
- Missing fixtures are generated through the snapshot update flow.

When should fixtures be updated?
Only when the update maps to an intentional behavior change, not merely to make tests pass.
How are volatile values handled?
They are normalized in code, not patched ad hoc in fixtures.
