Require current inspection access before applying a queued offline change
A contractor loses project access while offline, then reconnects with a batch of previously authorized edits.

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
A fictional field team inspects equipment with intermittent connectivity. Two tablets can edit the same checklist and an old upload may restore a deleted finding.
Setup prerequisites
- Create two local client-state simulators and a synthetic inspection API.
- Use fabricated notes and local attachment bytes.
Preceding work
Complete these dependencies, or supply their agreed outputs before taking this ticket.
Acceptance criteria
- Reauthorize each target at synchronization time.
- Reject revoked or cross-organization changes without partial hidden writes.
- Return safe per-operation outcomes under the declared batch policy.
Implementation constraints
- Offline possession of data is not continuing write authority.
Verification to include
- Apply a queued edit for a still-authorized actor.
- Revoke access before reconnect and verify no inspection mutation.
Deliverables
- Sync authorization boundary
Rollout and recovery
Enable scope checks before bulk sync; retain rejected local operations for user review.
Value of the work
For the engineer: Practice offline synchronization, causal revisions and conflict resolution.
For the team: Review whether field work survives disconnection without hiding conflicting observations.
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.
