Codex Desktop 26.609.71450 on macOS triggers syspolicyd FD/CPU runaway

Codex Desktop started triggering a severe macOS syspolicyd runaway after the latest update. This is the desktop app, not the CLI. Environment: * macOS on Apple Silicon * Codex Desktop: 26.609.71450 * CFBundleVersion: 3965 * App path: /Applications/Codex.app * Gatekeeper assessments: enabled * SIP/Gatekeeper were not disabled Symptoms: * Launching Codex Desktop causes syspolicyd to climb to 120% to 250% CPU. * Codex itself also spikes CPU while this is happening. * spctl --assess --type execute --verbose=4 /Applications/Codex.app returns: /Applications/Codex.app: Too many open files * lsof shows thousands of syspolicyd file descriptors pointing to the same Codex executable: /Applications/Codex.app/Contents/MacOS/Codex Observed counts: * syspolicyd FD count for the Codex executable: approximately 2538 to 2540 * launchctl maxfiles was raised to 65536 / unlimited and persisted through /Library/LaunchDaemons/local.maxfiles.plist * Raising maxfiles reduces the immediate FD-limit failure mode, but syspolicyd still returns to high CPU after Codex is launched. * Rebooting macOS does not resolve the issue once Codex Desktop is opened again. Things already tried: sudo xattr -cr /Applications/Codex.app sudo killall syspolicyd sudo kill -9 $(pgrep -x syspolicyd) sudo launchctl limit maxfiles 65536 184320 Current result: * syspolicyd is relaunched by macOS and resumes the evaluation loop. * The repeated FD target is still /Applications/Codex.app/Contents/MacOS/Codex. * I do not want to disable SIP or globally disable Gatekeeper for this. This looks like Codex Desktop is repeatedly triggering Gatekeeper / syspolicy executable assessment and leaking or retaining FDs in syspolicyd. Please route this to the Desktop App team if this forum is the right place; if there is a better Desktop-specific issue tracker, please point me there.
