- Added a new Invariant: `ValidPseudoAccounts` which checks that all pseudo-accounts behave consistently through creation and updates, and that no "real" accounts look like pseudo-accounts (which means they don't have a 0 sequence).
- `to_short_string(base_uint)`. Like `to_string`, but only returns the first 8 characters. (Similar to how a git commit ID can be abbreviated.) Used as a wrapped sink to prefix most transaction-related messages. More can be added later.
- `XRPL_ASSERT_PARTS`. Convenience wrapper for `XRPL_ASSERT`, which takes the `function` and `description` as separate parameters.
- `SField::sMD_PseudoAccount`. Metadata option for `SField` definitions to indicate that the field, if set in an `AccountRoot` indicates that account is a pseudo-account. Removes the need for hard-coded field lists all over the place. Added the flag to `AMMID` and `VaultID`.
- Added functionality to `SField` ctor to detect both code and name collisions using asserts. And require all SFields to have a name
- Convenience type aliases `STLedgerEntry::const_pointer` and `STLedgerEntry::const_ref`. (`SLE` is an alias to `STLedgerEntry`.)
- Generalized `feeunit.h` (`TaggedFee`) into `unit.h` (`ValueUnit`) and added new "BIPS"-related tags for future use. Also refactored the type restrictions to use Concepts.
- Restructured `transactions.macro` to do two big things
1. Include the `#include` directives for transactor header files directly in the macro file. Removes the need to update `applySteps.cpp` and the resulting conflicts.
2. Added a `privileges` parameter to the `TRANSACTION` macro, which specifies some of the operations a transaction is allowed to do. These `privileges` are enforced by invariant checks. Again, removed the need to update scattered lists of transaction types in various checks.
- Unit tests:
1. Moved more helper functions into `TestHelpers.h` and `.cpp`.
2. Cleaned up the namespaces to prevent / mitigate random collisions and ambiguous symbols, particularly in unity builds.
3. Generalized `Env::balance` to add support for `MPTIssue` and `Asset`.
4. Added a set of helper classes to simplify `Env` transaction parameter classes: `JTxField`, `JTxFieldWrapper`, and a bunch of classes derived or aliased from it. For an example of how awesome it is, check the changes `src/test/jtx/escrow.h` for how much simpler the definitions are for `finish_time`, `cancel_time`, `condition`, and `fulfillment`.
5. Generalized several of the amount-related helper classes to understand `Asset`s.
6. `env.balance` for an MPT issuer will return a negative number (or 0) for consistency with IOUs.
* Add and Scale to VaultCreate
* Add round-trip calculation to VaultDeposit VaultWithdraw and VaultClawback
* Implement Number::truncate() for VaultClawback
* Add rounding to DepositWithdraw
* Disallow zero shares withdraw or deposit with tecPRECISION_LOSS
* Return tecPATH_DRY on overflow when converting shares/assets
* Remove empty shares MPToken in clawback or withdraw (except for vault owner)
* Implicitly create shares MPToken for vault owner in VaultCreate
* Review feedback: defensive checks in shares/assets calculations

This change introduces two key optimizations:
* Mutex scope reduction: Limits the lock to individual partitions within `TaggedCache`, reducing contention.
* Decoupling: Removes the tight coupling between `LedgerHistory` and `TaggedCache`, improving modularity and testability.
Lock contention analysis based on eBPF showed significant improvements as a result of this change.
- Specification: [XRPLF/XRPL-Standards 56](https://github.com/XRPLF/XRPL-Standards/blob/master/XLS-0056d-batch/README.md)
- Amendment: `Batch`
- Implements execution of multiple transactions within a single batch transaction with four execution modes: `tfAllOrNothing`, `tfOnlyOne`, `tfUntilFailure`, and `tfIndependent`.
- Enables atomic multi-party transactions where multiple accounts can participate in a single batch, with up to 8 inner transactions and 8 batch signers per batch transaction.
- Inner transactions use `tfInnerBatchTxn` flag with zero fees, no signature, and empty signing public key.
- Inner transactions are applied after the outer batch succeeds via the `applyBatchTransactions` function in apply.cpp.
- Network layer prevents relay of transactions with `tfInnerBatchTxn` flag - each peer applies inner transactions locally from the batch.
- Batch transactions are excluded from AccountDelegate permissions but inner transactions retain full delegation support.
- Metadata includes `ParentBatchID` linking inner transactions to their containing batch for traceability and auditing.
- Extended STTx with batch-specific signature verification methods and added protocol structures (`sfRawTransactions`, `sfBatchSigners`).
- 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 implements the account permission delegation described in XLS-75d, see https://github.com/XRPLF/XRPL-Standards/pull/257.
* Introduces transaction-level and granular permissions that can be delegated to other accounts.
* Adds `DelegateSet` transaction to grant specified permissions to another account.
* Adds `ltDelegate` ledger object to maintain the permission list for delegating/delegated account pair.
* Adds an optional `Delegate` field in common fields, allowing a delegated account to send transactions on behalf of the delegating account within the granted permission scope. The `Account` field remains the delegating account; the `Delegate` field specifies the delegated account. The transaction is signed by the delegated account.
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.
Adds two CMake functions:
* add_module(library subdirectory): Declares an OBJECT "library" (a CMake abstraction for a collection of object files) with sources from the given subdirectory of the given library, representing a module. Isolates the module's headers by creating a subdirectory in the build directory, e.g. .build/tmp123, that contains just a symlink, e.g. .build/tmp123/basics, to the module's header directory, e.g. include/xrpl/basics, in the source directory, and putting .build/tmp123 (but not include/xrpl) on the include path of the module sources. This prevents the module sources from including headers not explicitly linked to the module in CMake with target_link_libraries.
* target_link_modules(library scope modules...): Links the library target to each of the module targets, and removes their sources from its source list (so they are not compiled and linked twice).
Uses these functions to separate and explicitly link modules in libxrpl:
Level 01: beast
Level 02: basics
Level 03: json, crypto
Level 04: protocol
Level 05: resource, server
