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.
- CLINK-101 · Reject malformed mobile invitation routes before navigation
- CLINK-102 · Explain expired mobile invitations without automatic retries
- CLINK-103 · Retain a mobile link destination through local sign-in
- CLINK-104 · Recheck mobile work-item access after account switching
- CLINK-105 · Serialize mobile session refresh for simultaneous requests
- CLINK-106 · Cancel pending mobile navigation when invitation ownership changes
- CLINK-107 · Recover mobile sign-in continuation after process restart
- CLINK-108 · Keep the mobile Back stack free of completed sign-in screens
- CLINK-109 · Expose revoked mobile sessions before showing cached team content
Acceptance criteria
- Logs exclude IDs and tokens
- Known failures have stable categories
- Unexpected errors use bounded safe summaries
Implementation constraints
- Verify with synthetic secret-like links.
Verification to include
- Log valid route outcome
- Reject token-bearing malformed URL
Deliverables
- Diagnostic event contract
Rollout and recovery
Disable link diagnostics on redaction failure.
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.
