Adds the VPS-side orchestrator for Option A (ADR 2026-06-22):
the Coolify KVM8 VPS (76.13.220.15) drives PRAutoBlogger generation
on prod synchronously over a held-open SSH session, escaping
Hostinger's ~10-min background-PHP-process kill.
Files:
infra/vps/orchestrate-generation.sh
- SSH to Hostinger; reaper sweep; wp prautoblogger generate --sync
- Lock-aware: skips if run in-flight (plugin DB mutex)
- Structured log lines (captured by systemd journal)
- Failure alert: email to cto@peptiderepo.com via system mail
- DRY_RUN=1 mode: echoes commands without executing generation
- All config via env vars (SSH_KEY, SSH_HOST, etc.); no hardcoded secrets
- SSH key referenced by PATH (/root/.ssh/hostinger_prod_ed25519)
infra/vps/install-orchestrator.sh
- Installs orchestrator to /opt/prab-orchestrator/
- Installs systemd .service and .timer to /etc/systemd/system/
- Does NOT enable or start timer (explicit post-QA cutover step)
infra/vps/prab-generation.service
- Type=oneshot, User=root, TimeoutStartSec=7200 (covers 32-min LLM calls)
- Restart=no (timer retries next day on failure)
infra/vps/prab-generation.timer
- OnCalendar=*-*-* 06:00:00 UTC, Persistent=true, RandomizedDelaySec=300
DO NOT install or enable on the VPS this round — QA-gated, hold for CTO review.
