ADR-0004: Parallel, integrated money + AI-usage ledgers

  • Status: Accepted · Date: 2026-05-30

Context

AI utilization is an economy unto itself and must be treated as first-class alongside money.

Decision

Run two parallel, closely integrated ledgers — a Money ledger and an AI-Usage ledger — reconciled via a configurable cross-rate ($/unit). Design: docs/financial-system.md; principle: hr/policies/ai-economy.md. Plan-phase.

Consequences

  • A unified “cost of work” view and per-venture/agent P&L become possible.
  • More moving parts than a single ledger; justified by treating AI usage as a currency. Owner: Finance (planned unit).
