Port padelnomics' schedule-aware Python supervisor to materia: - src/materia/supervisor.py — croniter scheduling, topological wave execution (parallel independent workflows), tag-based git pull + deploy, status CLI subcommand - infra/supervisor/workflows.toml — workflow registry (psd daily, cot weekly, prices daily, ice daily, weather daily) - infra/supervisor/materia-supervisor.service — updated ExecStart to Python supervisor, added SUPERVISOR_GIT_PULL=1 Adaptations from padelnomics: - Uses extract_core.state.open_state_db (not padelnomics_extract.utils) - uv run sqlmesh -p transform/sqlmesh_materia run - uv run materia pipeline run export_serving - web/deploy.sh path (materia's deploy.sh is under web/) - Removed proxy_mode (not used in materia) Also: add croniter dependency to src/materia, delete old supervisor.sh.

Materia Infrastructure
Single-server local-first setup for BeanFlows.coffee on Hetzner NVMe.
Architecture
Hetzner Server (NVMe)
├── /opt/materia/ # Git repo, code, uv environment
├── /data/materia/landing/ # Extracted USDA data (year/month subdirs)
├── /data/materia/lakehouse.duckdb # SQLMesh output database
└── systemd services:
├── materia-supervisor # Pulls git, runs extract + transform daily
└── materia-backup.timer # Syncs landing/ to R2 every 6 hours
Data Flow
- Extract: USDA API →
/data/materia/landing/psd/{year}/{month}/{etag}.csv.gzip - Transform: SQLMesh reads landing CSVs → writes to
/data/materia/lakehouse.duckdb - Backup: rclone syncs
/data/materia/landing/→ R2materia-raw/landing/ - Web: Reads
lakehouse.duckdb(read-only)
Setup
Prerequisites
- Hetzner server with NVMe storage
- Pulumi ESC configured (
beanflows/prodenvironment) GITLAB_READ_TOKENandPULUMI_ACCESS_TOKENset
Bootstrap
# From local machine or CI:
ssh root@<server_ip> 'bash -s' < infra/bootstrap_supervisor.sh
This installs dependencies, clones the repo, creates data directories, and starts the supervisor service.
R2 Backup
- Install rclone:
apt install rclone - Copy and configure:
cp infra/backup/rclone.conf.example /root/.config/rclone/rclone.conf - Fill in R2 credentials from Pulumi ESC
- Install systemd units:
cp infra/backup/materia-backup.service /etc/systemd/system/
cp infra/backup/materia-backup.timer /etc/systemd/system/
systemctl daemon-reload
systemctl enable --now materia-backup.timer
Pulumi IaC
Still manages Cloudflare R2 buckets and can provision Hetzner instances:
cd infra
pulumi login
pulumi stack select prod
pulumi up
Monitoring
# Supervisor status and logs
systemctl status materia-supervisor
journalctl -u materia-supervisor -f
# Backup timer status
systemctl list-timers materia-backup.timer
journalctl -u materia-backup -f
Cost
| Resource | Type | Cost |
