01 / Context
Problem
SIGNAL/LEDGER breaks a paid AI call into a budget, payment source, generated report, and receipt record so agent activity can be reviewed beyond the chat transcript.
Boundaries
- The content represents demo and testnet experiments; it does not claim real revenue or mainnet settlement volume.
- The external project opens independently, and this site does not probe its availability during builds.
- The receipt is presented as a product evidence format; its final trust level depends on the deployed network and transaction source.
