Activity works across every ADE surface
- The inbox now covers every session. Activity groups live sessions and events by urgency, adds filters and detail views, supports per-machine muting and durable acknowledgements, and keeps desktop, hosted web, and ADE Code aligned.
- iPhone and widgets stay current. Background refresh, retry-safe acknowledgements, richer activity rows, hub status, and a multi-session Lock Screen widget carry the same state and actions onto iOS.
- The notch becomes a compact activity surface. Event toasts, counts, hover cards, menu-bar fallback, presentation limits, and deduplication make the native helper useful without letting bursts take over the screen.
Cross-machine Work is safer
- Remote CLI sessions behave like local work. Machine-scoped retention, routing, project switching, deep links, stop actions, and error reporting now resolve against the full cross-machine session set.
- Ownership survives provider handoff. Per-launch ownership markers prevent another machine from adopting the wrong Codex process, while foreign sessions keep their owning runtime and project context.
GitHub failures recover cleanly
- Credentials fail over instead of stalling. GitHub operations prefer healthy user credentials, switch away from exhausted or invalid paths, and attribute failures to the credential that actually handled the request.
- Polling respects rate limits. Conditional requests, cooldown-aware refreshes, and bounded fallback behavior reduce unnecessary GitHub traffic while preserving current PR state.
