Type: Guide
Reading time: 12 min

## 1. When offline-first is justified

Use this section to evaluate when offline-first is justified, including operational constraints, architecture boundaries, evidence, ownership, and failure handling.

## 2. Local data and write ownership

Use this section to evaluate local data and write ownership, including operational constraints, architecture boundaries, evidence, ownership, and failure handling.

## 3. Synchronization and retry policy

Use this section to evaluate synchronization and retry policy, including operational constraints, architecture boundaries, evidence, ownership, and failure handling.

## 4. Conflict resolution

Use this section to evaluate conflict resolution, including operational constraints, architecture boundaries, evidence, ownership, and failure handling.

## 5. Observability and support

Use this section to evaluate observability and support, including operational constraints, architecture boundaries, evidence, ownership, and failure handling.
