Project context
Fictional membership portal Juniper manages synthetic team settings. Use locally owned components and a local settings adapter.
Setup prerequisites
- Create synthetic settings forms and destructive-action stubs.
- Provide delayed success, rejection and removed-trigger cases.
Preceding work
Complete these dependencies, or supply their agreed outputs before taking this ticket.
Acceptance criteria
- Existing trigger regains focus
- Deleted trigger uses nearest contextual control
- Failure keeps focus inside dialog
Implementation constraints
- Resolve fallback after committed row removal.
Verification to include
- Save without deleting trigger
- Delete the trigger's row
Deliverables
- Focus-return resolver and cases
Rollout and recovery
Keep an action-result placeholder if no valid target exists.
Value of the work
For the engineer: Practice focus containment, dismissal and asynchronous feedback.
For the team: Inspect whether shared UI primitives protect users across many product flows.
Evidence boundaries
Outcome Evidence: Tests, patches, and runbooks are requested deliverables. They become Outcome Evidence only through a qualified Mission and immutable Evidence IDs.
Ownership Evidence: Independent adaptation must be observed under a declared verification policy and cite immutable Evidence IDs. Completing a planning ticket establishes no Ownership Evidence.
