A reserve is more than a wallet. It is a governed state of balances, permissions, classifications, conversion rules, commitments and audit obligations.
Reserve assets can be segregated into allocation, liquidity, governance and stabilisation functions so one balance is not counted twice or deployed without policy.

Convert or allocate Bitcoin ecosystem reserve assets under project-specific limits and approval thresholds.
Provide finite liquidity capacity without making unsupported open-ended redemption promises.
Reserve receipt, conversion or fiat settlement can become a validation input for registry issuance.
Define budget policy for compliance, administration, software and ecosystem operations.
Cold storage, institutional custody, operational wallets and exchange accounts receive separate limits and reconciliation.
No single actor should control full reserve movement, project approval and registry execution.
Reserve reports can combine signed wallet messages, custody attestations, liabilities and reserve classifications.
