This change introduces the `featurePermissionDelegationV1_1` amendment, which is designed to supersede both `featurePermissionDelegation` and `fixDelegateV1_1 amendments, which should be considered deprecated. The `checkPermission` function will now return `terNO_DELEGATE_PERMISSION` when a delegate transaction lacks the necessary permissions.
- Amendment: fixDelegateV1_1
- In DelegateSet, disallow invalid PermissionValues like 0, and transaction values when the transaction's amendment is not enabled. Acts as if the transaction doesn't exist, which is the same thing older versions without the amendment will do.
- Payment burn/mint should disallow DEX currency exchange.
- Support MPT for Payment burn/mint.
The tests that ensure `tfInnerBatchTxn` won't block delegated transactions silently fail in `Delegate_test.cpp`. This change removes these cases from that file and adds them to `Batch_test.cpp` instead where they do not silently fail, because there the batch delegate results are explicitly checked. Moving them to that file further avoids refactoring many helper functions.
* Adds `tecNO_DELEGATE_PERMISSION` for unauthorized transactions sent by a delegated account.
* Returns `tecNO_TARGET` instead of `terNO_ACCOUNT` for the `DelegateSet` transaction if the delegated account does not exist.
* Fixes `tfFullyCanonicalSig` and `tfInnerBatchTxn` blocking transactions issue by adding `tfUniversal` in the permission related masks in `txFlags.h`
- 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`).
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.
