Usage

ladon --config /etc/stack/Config.toml check
ladon --config /etc/stack/Config.toml pool

check success output:

configuration valid: store_driver=sqlite, table=derived_addresses, chains=2, pool_target=1000

pool creates its table when needed and refills each chain when available rows (is_used IS NULL) fall below threshold. It continues at the highest persisted index plus one. Consumers should atomically claim rows and set is_used = true to preserve index continuity. Logs use stderr; validation failures exit non-zero without disclosing secret values.
