release(v1.7.41-alpha): post-OTA auto-rollback so a bad release cannot strand the fleet Closes failure mode FM5 from docs/bulletproof-containers.md: the v1.7.38 + v1.7.39 rollouts left every affected node on an unreachable UI (nginx 500) with no recovery path short of SSH. This release adds a self-check guardrail to the update flow. What changed: - apply_update() writes a pending-verify marker with old+new version and a 150s deadline immediately before scheduling the service restart. - verify_pending_update() runs from main.rs startup. If the marker is present and within its freshness window, the new binary waits 15s for nginx + backend to settle, then probes https://127.0.0.1/ every 5s for up to 90s (self-signed certs accepted). - On any probe success within the window, the marker is cleared and nothing else happens. - On window-exhaust, the new binary: 1. Moves the broken /opt/archipelago/web-ui to web-ui.failed.<ts> (quarantined, not deleted, so we can post-mortem). 2. Restores web-ui.bak on top of web-ui. 3. Calls rollback_update() to restore the previous binary. 4. Updates state.current_version to reflect the rollback. 5. systemctl --no-block restart archipelago so the OLD binary boots. - Markers older than 10 minutes are treated as stale and cleared without probing, so a crashed-during-startup marker from weeks ago cannot spontaneously roll back a healthy node on a later reboot. - rollback_update() binary copy now goes through host_sudo instead of tokio::fs::copy, so it escapes the service's ProtectSystem=strict mount namespace. Without this, the rollback silently failed with EROFS on /usr/local/bin and orphaned the rollback - the exact opposite of what auto-rollback is for. Tests: 4 new unit tests in update::tests covering marker round-trip, absent-marker noop, no-panic on verify_pending_update with nothing to verify, and an invariant assert that the 90s probe window stays below the 600s stale threshold. All passing. Side fix: scripts/create-release-manifest.sh was dying with exit 141 (SIGPIPE from tar tvzf pipe head pipe awk) under set -euo pipefail. Replaced with a single awk NR==1 that doesn't short-circuit the upstream pipe, so the release-build flow is idempotent again.
