Why it matters
Handoff can reduce the Git and setup work required to switch machines, but developers still need a precise contract for files, secrets and failed transfers.
Developing Adventures (@DevAdventur3s) demonstrated Codex moving a coding chat and its project state from one Mac to another on September 13th, including an untracked file that arrived with the same hash. The test used a modified Codex build with feature flags enabled, so it was a close look at an existing Handoff workflow rather than a new OpenAI release.
