Field percentages are editorial estimates of the ticket's engineering focus. They total 100%; they are not measured time, proficiency scores, or ownership evidence.
Review it, then add it to your workspace.
The board opens an editable draft; nothing is saved until you confirm it. Sign-in and workspace permissions apply, and Demo boards remain ephemeral.
Project context
Fictional team-planning app Finch opens invitations and shared work items. All users and sessions are synthetic; implement the app in an emulator without external identity credentials.
Setup prerequisites
- Create a local session adapter with expiry and revocation.
- Define synthetic invitation and work-item links.
Preceding work
Complete these dependencies, or supply their agreed outputs before taking this ticket.
Acceptance criteria
- Valid destination resumes once
- External destinations are rejected
- Cancel sign-in clears pending intent
Implementation constraints
- Store route identity, not raw credentials or URL tokens.
Verification to include
- Sign in and resume
- Cancel then sign in normally
Deliverables
- Pending-route coordinator
Rollout and recovery
Disable continuation if validation fails.
Value of the work
For the engineer: Practice navigation state, capability checks and session boundaries.
For the team: Inspect whether links remain useful without bypassing authorization.
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.
