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
- Tab stays in active confirmation
- Escape closes only top layer
- Parent state survives confirmation cancellation
Implementation constraints
- Use the accessible primitive rather than manual document-wide traps.
Verification to include
- Cycle Tab through nested dialog
- Cancel then resume parent form
Deliverables
- Nested-dialog composition tests
Rollout and recovery
Replace nested confirmation with an inline confirmation step.
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.
