Pattern Decisions This Source Supports

Pattern Supported decision Required contract Claim note
Offline mobile retry Choose offline mobile retry when a mobile action should be preserved and retried after connection loss, flaky network, app backgrounding, or policy-limited connectivity. The UI never reports server success for a mobile action that is only saved locally or queued. Supports queued failed requests, later replay, retry timing, fallback replay, and retention limits.
Sync state Choose sync state when local and remote copies both matter and their reconciliation status affects trust, next action, or data integrity. The sync surface never upgrades local saved or queued work to synced until the remote system confirms acceptance. Workbox supports queued failed requests, sync-event replay, browser-managed retry timing, and retention limits.
