Since the autoscaler takeover (static codex-cloud-worker stopped at
2026-10-26 07:02:55, disabled by design), the monitor's worker check
(systemctl is-active codex-cloud-worker) has failed every 5 minutes
while the real workers were healthy (health worker_ok kept passing,
GET /workers shows live autoscale-1 + host-1). A monitor that always
fails masks real failures. Fix: pass if either codex-autoscaler or
codex-cloud-worker is active, covering both deployment modes; the
health check still covers worker heartbeat freshness.
Deploy: deploy.sh builds tarball, backs up current code (keep 3),
deploys, restarts, health-gates 60s (ok/backend=postgres/db_ok),
auto-rolls back on failure; rollback.sh restores latest backup.
Rollback is code-only, DB migrations are additive-only so old
code can still read new columns.
Backup: restore_postgres refuses to restore into the production
DB name unless explicitly allowed (drill never allows it);
restore-drill.sh backs up fresh, restores to a test DB, compares
tasks/projects/users/audit row counts, drops the test DB.
Monitoring: worker writes heartbeat file every loop (atomic
replace, failure only logged); GET /health adds
worker_last_seen_seconds_ago + worker_ok (180s default, env
tunable, still HTTP 200 when worker is stale); monitor.sh
checks server/worker/health/pg_isready/docker-postgres/disk/
app dir as one JSON line, exit non-zero on any fail, plus
systemd timer every 5 minutes. Push alerting to chat still
needs a separate channel decision (SSH key or webhook URL).
Multi-user: verify-multiuser.py creates test users/projects
in memory-key only, checks RBAC via real HTTP API (owner/
maintainer/contributor/viewer, cross-project isolation,
merge 200/403/409, no-key 401), test tasks carry a never-
satisfiable dependency so the production worker never claims
them, cleanup deletes only multiuser-test- rows (audit log
is append-only and keeps test entries by design).
Tests: host 27 pass, cloud 298 pass (8 skipped are
environment-dependent real-Postgres tests).
