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 on-call team wants an assistant that joins alerts, deployment notes, and runbooks. Incomplete telemetry and hostile log content make unsupported conclusions dangerous.
Setup prerequisites
- Author synthetic alerts, deployment records, and runbooks plus deterministic tool and model doubles.
Preceding work
No earlier ticket is required. Complete the project setup above.
Acceptance criteria
- Normalize timestamps to UTC.
- Preserve source identity and original timestamp.
- Mark missing or uncertain event times.
Implementation constraints
- Do not invent ordering for ambiguous records.
Verification to include
- Merge valid records in stable order.
- Keep equal or missing timestamps visibly uncertain.
Deliverables
- Timeline schema.
Rollout and recovery
Import synthetic records first; retain original source records.
Value of the work
For the engineer: Practice constrained tool use, operational uncertainty, and traceable AI outputs.
For the team: Produce concise incident drafts that preserve source traceability and operator control.
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.
