Merged — locally validated (23/23 focused probe-isolation tests, typecheck:core clean, file-size/changelog gates green). Reconciled with today's #8367 (codexAccount module extraction, merged earlier): the persistCodexQuotaState closure this PR touched had been extracted into persistCodexChildQuotaResponse — applied the same probe-origin isolation guard (!shouldIsolateProbeFailures()) at its new call site instead of reintroducing the old inline closure. Thanks for closing this real gap!
