The goal of CLBOSS is to make the node able to pay and receive payments
on the lightning network reliably without needing active management.
It is not a tool to run a profitable lightning node and it can lose some sats on fees.

CLBOSS does the following automatically:
- Open channels to other, useful nodes when fees are low and there are onchain funds
- Acquire incoming capacity via boltz.exchange swaps (these funds return onchain)
- Rebalance open channels by self-payment (including JIT rebalancer)
- Set forwarding fees so that they're competitive to other nodes
