# Compute and ledger

Describe Compute as “prepaid usage credits that power intelligent agents.” Never call it stock, equity, an investment, passive income, ROI, or appreciation.

## Ledger rule

Amounts and balances live in immutable double-entry PostgreSQL ledger entries. The graph stores references and organizational relationships. Settlement rails remain authoritative for external finality.

## Receipt minimum

Organization, buyer, purchase type, units, raw model cost, Agency pricing, Guest/Member basis, fees, total, currency, payment rail, mode, settlement reference, issuance reference, lineage snapshot, allocation policy, and Records.

## Defaults subject to current policy

Kinship Member Agency Multiple defaults to 7× raw intelligence cost. Guest charge defaults to 2× the Member charge. A 20% liquidity value is a policy default minimum, not an immutable protocol rule. Retrieve current policy before use.

Missing lineage ancestors are skipped upward; after the traversal limit, route remainder to the named reserve. Never fabricate ancestors.
