What this role pays attention to
- Follow one user action through validation, authorization, storage and response.
- Plan old/new client compatibility before changing shared contracts.
Decision guidance
Prefer a complete thin slice when layers are uncertain; split changes when independent rollout is required.
Concrete contribution
Produce one end-to-end contract trace from user action through authorization and storage to the rendered result, identifying old/new client compatibility before changing any layer.
Scope boundary
Do not expand a small feature into a platform rewrite.
Relevant checks
- Test the end-to-end outcome and negative authorization path.
- Check migration and client compatibility against the deployment order.
