Keep the remaining current-state Agent Notes in line with removing the hosted serial-linux job (PR #2744), per the implemented-note rule that mechanisms stay current in the same change that alters them: - 2026-07-30-web-browser-snapshot-ci-gate (L15/L21): the hosted default-branch Linux serial job no longer produces the browser cache; pull requests restore the archived cache without a master producer, and only the self-hosted standby runs the comparison on master. - 2026-07-24-web-gui-browser-e2e-lane (L49): no hosted Linux serial producer of the browser cache remains; the self-hosted standby runs the same gate. - 2026-07-23-portable-required-pull-request-ci (L19): the serial completeness check is now provided by the self-hosted vm-backup/dsh-win-ci standby lanes, with serial-macos as the only disabled hosted serial. - 2026-07-22-evidence-based-larger-hosted-runners (L17/L53/L73): serial completeness evidence comes from the self-hosted standby pools; no hosted Linux serial reference remains. All four en/zh pairs updated with consistent current-state wording (no deletion narrative) and i18n hashes re-recorded; note-format still passes.
