Project context

Fictional studio Loom assigns editorial shifts. Build synthetic shifts and a local scheduling adapter; no real staff records are used.

Setup prerequisites

Create synthetic shifts including overlaps and daylight-saving boundaries.
Implement a local schedule revision adapter.

Preceding work

Complete these dependencies, or supply their agreed outputs before taking this ticket.

Acceptance criteria

Next chronological shift receives focus
Empty day focuses its heading control
Failed deletion retains original focus

Implementation constraints

Resolve targets after committed DOM updates.

Verification to include

Delete middle shift
Reject deletion and inspect focus

Deliverables

Focus resolver and deletion checks

Rollout and recovery

Keep deleted-row placeholder temporarily if focus restoration fails.

Value of the work

For the engineer: Practice focus models and accessible alternatives for spatial interfaces.

For the team: Inspect whether scheduling remains usable across input methods and failure states.

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.
