This change decouples `ledger` from `xrpld/app`, and therefore fully clears the path to the modularisation of the ledger component. Before this change, `View.cpp` relied on `MPTokenAuthorize::authorize; this change moves `MPTokenAuthorize::authorize` to `View.cpp` to invert the dependency, making ledger a standalone module.
#5224 added (among other things) a `VaultWithdraw` transaction that allows setting the recipient of the withdrawn funds in the `Destination` transaction field. This technically turns this transaction into a payment, and in some respect the implementation does follow payment rules, e.g. enforcement of `lsfRequireDestTag` or `lsfDepositAuth`, or that MPT transfer has destination `MPToken`. However for IOUs, it missed verification that the destination account has a trust line to the asset issuer. Since the default behavior of `accountSendIOU` is to create this trust line (if missing), this is what `VaultWithdraw` currently does. This is incorrect, since the `Destination` might not be interested in holding the asset in question; this basically enables spammy transfers. This change, therefore, removes automatic creation of a trust line to the `Destination` account in `VaultWithdraw`.
- Specification: https://github.com/XRPLF/XRPL-Standards/pull/272
- Amendment: `TokenEscrow`
- Enables escrowing of IOU and MPT tokens in addition to native XRP.
- Allows accounts to lock issued tokens (IOU/MPT) in escrow objects, with support for freeze, authorization, and transfer rates.
- Adds new ledger fields (`sfLockedAmount`, `sfIssuerNode`, etc.) to track locked balances for IOU and MPT escrows.
- Updates EscrowCreate, EscrowFinish, and EscrowCancel transaction logic to support IOU and MPT assets, including proper handling of trustlines and MPT authorization, transfer rates, and locked balances.
- Enforces invariant checks for escrowed IOU/MPT amounts.
- Extends GatewayBalances RPC to report locked (escrowed) balances.
Before #5224, the pseudoaccount ID was calculated using prefix expressed in `std::uint16_t`. The refactoring to move the pseudoaccount ID calculation to View.cpp had accidentally changed the prefix type to `int` (derived from `auto i = 0`) which in turn changed the length of the input to `sha512Half` from 2 bytes to 4, altering the result.
This resulted in a different ID of the pseudoaccount calculated from the function after the refactoring, breaking the ledger. This impacts AMMCreate, even when the `SingleAssetVault` amendment is not active. This change restores the prefix type to `std::uint16_t`.
- Specification: XRPLF/XRPL-Standards#239
- Amendment: `SingleAssetVault`
- Implements a vault feature used to store a fungible asset (XRP, IOU, or MPT, but not NFT) and to receive shares in the vault (an MPT) in exchange.
- A vault can be private or public.
- A private vault can use permissioned domains, subject to the `PermissionedDomains` amendment.
- Shares can be exchanged back into asset with `VaultWithdraw`.
- Permissions on the asset in the vault are transitively applied on shares in the vault.
- Issuer of the asset in the vault can clawback with `VaultClawback`.
- Extended `MPTokenIssuance` with `DomainID`, used by the permissioned domain on the vault shares.

This change introduces a new fix amendment (`fixPayChanV1`) that prevents the creation of new `PaymentChannelCreate` transaction with a `CancelAfter` time less than the current ledger time. It piggy backs off of fix1571.
Once the amendment is activated, creating a new `PaymentChannel` will require that if you specify the `CancelAfter` time/value, that value must be greater than or equal to the current ledger time.
Currently users can create a payment channel where the `CancelAfter` time is before the current ledger time. This results in the payment channel being immediately closed on the next PaymentChannel transaction.
The codebase is filled with includes that are unused, and which thus can be removed. At the same time, the files often do not include all headers that contain the definitions used in those files. This change uses clang-format and clang-tidy to clean up the includes, with minor manual intervention to ensure the code compiles on all platforms.
- spec: XRPLF/XRPL-Standards#220
- amendment: "DeepFreeze"
- implemented deep freeze spec to allow token issuers to prevent currency holders from being able to acquire more of these tokens.
- in combination with normal freeze, deep freeze effectively prevents any balance trust line balance change of a currency holder (except direct issuer <-> holder payments).
- added 2 new invariant checks to verify that deep freeze cannot be enacted without normal freeze and transfer is not frozen.
- made some fixes to existing freeze handling.
