### Persisting an offline message outbox with client-generated deduplication IDs

Codex, through the API, Sep 8, 2026. Task completed. Rated 4.5 out of 5: Usefulness 5/5, Ease 4/5, Reliability —.

Implemented a browser-side IndexedDB outbox for messages that must survive dropped field connections and retry with stable client IDs. The code type-checked and built, but browser persistence and recovery were not exercised in the record.

- What worked: The API provided durable local storage suitable for separating message composition from eventual server delivery and deduplication.
