- canSendToAccount will check if a destination tag is required _before_
checking if the sender is the destination. This is the original
VaultWithdraw behavior, and I want to stay consistent.
- Correct interest rounding calculation
- Fix some comments
- Don't explicitly break out of the multiple payment loop for the final
payment. Assert that it will exit by the loop condition.
- Fix LoanSet.calculateBaseFee with multisign.
- Cleanups.
- Add View helper functions for Loan and Vault transactions
- preflightDestinationAndTag
- checkDestinationAndTag
- canSendToAccount
- Used the helpers in appropriate Loan and Vault transactions.
- They could also be used in older transactions, I'll save that for
later.
Amendments activated for more than 2 years can be retired. This change retires the fix1515 amendment.

- Implement a new helper accountCanSend, which is like accountHolds, but
returns a meaningful value for issuers, and will include the available
credit on the other side of a trust line. (The sfHighLimit or
sfLowLimit as appropriate.)
- Use this new helper when checking the available balance in LoanPay.
- Loan scale is completely irrelevant to integral types (XRP, MPT), and
the field is "soeDEFAULT", so when set to 0, it won't be stored on
ledger, saving a little bit of space.
- Move management fee calculations out of transactors an into the
appropriate functions in LendingHelpers.h.
- Rewrite how overpayments are handled. May changed based on numerical
analysis.
- Update, fix, and clean up unit tests. Includes adding tolerances for
some checks where an exact match is unlikely.
- Add "integral()" function to Asset to simplify a common check.
As XRPL network demand grows and ledger sizes increase, the default 4K NuDB block size becomes a performance bottleneck, especially on high-performance storage systems. Modern SSDs and enterprise storage often perform better with larger block sizes, but rippled previously had no way to configure this parameter. This change therefore implements configurable NuDB block size support, allowing operators to optimize storage performance based on their hardware configuration. The feature adds a new `nudb_block_size` configuration parameter that enables block sizes from 4K to 32K bytes, with comprehensive validation and backward compatibility.
Specific changes are:
- Implements `parseBlockSize()` function with validation.
- Adds `nudb_block_size` configuration parameter.
- Supports block sizes from 4K to 32K (power of 2).
- Adds comprehensive logging and error handling.
- Maintains backward compatibility with 4K default.
- Adds unit tests for block size validation.
- Updates configuration documentation with performance guidance.
- Marks feature as experimental.
- Applies code formatting fixes.

Similarly to other transaction typed that can create a trust line or MPToken for the transaction submitter (e.g. CashCheck #5285, EscrowFinish #5185 ), VaultWithdraw should enforce reserve before creating a new object. Additionally, the lsfRequireDestTag account flag should be enforced for the transaction submitter.

The default job timeout is 5 hours, while build times are anywhere between 4-20 mins and test times between 2-10. As a runner occasionally gets stuck, we should fail much quicker.

- Rename some of the helper functions / lambdas.
- Update tracked interestOwed field better at final payoff.
- Add checks in LoanSet that the fields can be represented in the asset
type, and update test that fails those checks
(testLoanPayComputePeriodicPaymentValidRateInvariant)
- Also check that the computed periodic payment can be represented as
the asset type, and doesn't round _UP_ to 0.
- Update asserts to account for more scenarios, including initial loan
computation.
- Implement AccountSendMulti
- Document the derivations of loan components.
- Add "loanPrincipalFromPeriodicPayment" helper.
- Removed sfReferencePrincipal
- LoanSet and LoanPay can create MPTokens as a side effect
- LoanPay will send the fee to cover if the broker owner is deep frozen,
and fail if both of them are deep frozen.
- LoanPay will check auth for the receivers, or create holdings for the
submitting account if needed.
- LoanSet will fail if principal requested is not positive
- Handle overpayment in a separate function
- Add a test helper to check that balance changes went as expected
- Fix more tests
- Tests not expected to pass.
- Check in LoanSet if a loan with interest actually has interest.
tecPRECISION_LOSS if not.
- Add checks in LoanPay for deep froze broker owner and pseudoaccount.
- Fix management fee calculations in LoanPay and associated LoanBroker
and Vault data updates.
- Make state tracking next payment due date optional.
- Add a test case showing multiple payments combined.
- Update more tests to work with the new fields.
- Primarily updating tests, and fixing stuff that didn't work.
- Tests still not expected to pass.
- Add Json::Value::isMember(StaticString) so SFields can be used.
- Validate more fields in ValidLoan Invariant
- Loan tests are not expected to pass.
- Refactor Number to put rounding logic into reusable functions.
- Add Number tests to explicitly test rounding - may be redundant, but
easy to reason about. Verifies that the default rounding matches
banker's rounding.
- Enable LoanManage. Apparently any remaining issues were fixed by the
previous commit's cleanups.
- Partially enabled LoanPay.
