iOS Remote only exposes a capped subset of sessions from connected hosts

Description

The iOS Remote view does not expose all Codex sessions available on a connected Mac. It returns only a capped recent subset across connected hosts, making older but still-active sessions undiscoverable and impossible to continue from the phone.

Remote's core purpose is to let a user access the Codex sessions on the connected computer. Returning an arbitrary subset without pagination, full search, or a clear limit makes the feature unreliable for users with many ongoing sessions.

Environment

• macOS ChatGPT desktop app: 26.727.51351
• Codex compatibility bundle: 26.715.52143
• ChatGPT iOS Remote
• Three connected hosts
• OpenAI Status reported operational during reproduction

Reproduction

1. Keep the Mac awake, online, signed in, and running the desktop app.
2. Confirm the Mac's Codex sessions and projects are visible locally.
3. Open Remote in the ChatGPT iOS app.
4. Inspect the sessions exposed across connected hosts.
5. Compare the Remote result with the connected Mac's local session inventory.

Measured result

• Connected Mac local inventory: 209 active session records
• Connected Mac archived inventory: 59 archived session records
• Cross-host recent-thread listing: exactly 50 total, even when requesting a limit of 500
• Of those 50, only 28 belong to the affected Mac
• Remaining returned sessions: 17 from one connected host and 5 from another
• No hosts were reported unavailable
• The affected Mac exposed five saved projects successfully
• The oldest Mac session returned by the cross-host listing was last updated July 30, while many older active local sessions still exist

This closely matches the iOS behavior: only about one quarter of the Mac's active sessions are visible.

Expected behavior

Remote should make every non-deleted session on a connected host discoverable and continuable, ideally through:

• complete paginated browsing;
• project/host filtering; and
• search across the full session inventory.

If a recent-only view is intentional, it should not be the only view and should clearly expose pagination or full search.

Actual behavior

Remote silently exposes a capped, cross-host recent subset. Older active sessions disappear from mobile even though they remain present and usable on the connected Mac.

Impact

Users cannot reliably continue established Codex work from iPhone. Creating or updating newer sessions pushes other valid sessions out of the visible Remote set, so session availability changes arbitrarily from day to day.

Likely area

The cross-host/Remote recent-thread aggregation appears capped at 50 and either does not paginate or the iOS client does not request/render subsequent pages.
