Description

Attempting to recover the agent-owned Browser tab by navigating from an isolated dev thread to /settings/general, with readiness none and timeoutMs 5000, returned Preview automation navigate timed out after 5000ms. Status still reported the tab as available and caller-owned. Earlier pair-page navigation had succeeded.
Windows, Codex harness, source 28416e9. Related snapshot issue: #28136. No tokens or private thread content are included. Please make recovery navigation work or return a specific unrecoverable state.

Reviewed candidate: #28154
Covers agent navigation and viewer address/history/reload paths by probing a hung renderer before navigation. Still blocked: the unresolved review correctly notes that Runtime.terminateExecution is fired without awaiting its acknowledgement before the probe resolves, allowing navigation to race termination. Await bounded termination within the caller budget and add a regression whose termination acknowledgement is deferred. The PR is currently conflicting with the base and needs an author-owned update. Windows/Electron runtime verification is not established.
Source/patch and GitHub review audit only in this pass; no new runtime verification. The candidate remains open and unmerged.

This is the same problem as #36365, so I'm closing it in favour of that one. If it is different, say how and it will be reopened.

Fixed by #36365, now on main: After this merge, preview_navigate can recover the caller-owned tab from a non-yielding page script and reach a same-site destination with readiness none or load, instead of retaining the old URL or timing out.
