Storage (v0.1)

DefendableRouter v0.1 persists to two places, both on local disk.

1. SQLite (relational state)

Members, datasets, compute nodes, jobs, leases, workers, and status events live in a local SQLite database:

sqlite:///./data/defendable_router.db

This is the default database_url in core/config.py (override via the DEFENDABLE_ROUTER_DATABASE_URL env var). SQLAlchemy ORM models back the API.

2. JSONL receipt ledger (books and records)

Every billable/lifecycle event appends a checksummed receipt line to a daily file:

./data/receipts/YYYY-MM-DD.receipts.jsonl

See Receipt Capture for the receipt fields, the canonical checksum algorithm, and the hash chain (seq + parent_hash) with its GET /receipts/verify.

🐝 Operator-grade · books and records · to the shed.
