Full Build — Both Views Together
Build the Error Listing and Error Detail as a single feature. Ship both views at once with all panels (version track, callers, similar issues, notes, common payload, performance).
Pros
- Complete experience from day one
- Design decisions can be made holistically
- Single backend API design pass
Cons
- Large scope — long time to first usable version
- Notes, similar issues, and common payload are exploratory features
- Backend regression coefficient + notes endpoints needed upfront
