PR: d1ae8dcc920f363ecc6785b043133e7110d8bd15
Chrome: /usr/bin/google-chrome; Playwright 1.60.0
Dev runner: serverPort=16733 webPort=8693; isolated homes
Data: actual app-created git project, Codex gpt-6.1-sol turns, UI deletion.
No event inserts, timestamp rewrites, fixtures, or mocks.
Clock: LD_PRELOAD libfaketime, FAKETIME=+21h then +28h, FAKETIME_DONT_FAKE_MONOTONIC=1, NO_FAKE_STAT=1. System/browser clocks unchanged.
Background compaction ran normally after startup delay. Restored normal process time before final turn.

Resume payloads: live thread expired cursor 134 < floor 159; shell expired cursor 133; valid thread/shell cursor 159; deleted thread cursor 100 < floor 127.
UI: cold reopen preserved all original replies and checkpoint diff. Expanded original command output and read marker. Deleted thread absent. After normal-time restart, real Codex read same file and returned AFTER-PRUNE-28144 retention-marker-28144.

Not verified: native mobile/Electron shells; other providers; relay/tunnel; native subagent promptSequence production anchors; unfinished legacy imports; an actual concurrent prune/replay overlap; a natural 24h wait. These are not claimed by this runtime pass.
