Josh added the read-only deploy key on 7 October 2026 (SHA256:51ice3W8...). The sync still said 'mirror' because ssh -T to GitHub
exits 1 after its greeting and observer-sync.sh runs under pipefail, so su ... | grep -q reported failure although grep had
matched (the same line by hand, without pipefail, said authenticated; shown under the unit's environment with systemd-run -v).
The probe's output is captured first. First github pass 07:30:54 UTC: the clone moved from the mirror's 8397781 to origin/master
8aab05ce, the observer restarted on it.
