Wallet and Ledger Architecture

Vault handles long-horizon reserves, Operational supports active spending, Escrow tracks pending settlement, and Delegated isolates agent-managed limits.

Each compartment keeps independent balances and policy hooks, enabling safer automation and least-privilege execution.

All state transitions produce balanced debit/credit entries. There is no direct balance mutation outside journal pathways.

Fixed-point Amount(i128) with 8-decimal scaling removes floating-point drift and ensures deterministic reconciliation across nodes.

Each transaction path includes idempotency metadata to prevent duplicate effects under retry conditions.

Wallet-level history is reconstructible from journal entries and WorldLine references, enabling post-incident replay.
