This change continues the thread naming work from #5691 and #5758, which enables more useful lock contention profiling by ensuring threads/jobs have short, stable, human-readable names (rather than being truncated/failing due to OS limits). This changes diagnostic naming only (thread names and job/load-event labels), not behavior.
Specific modifications are:
* Shortens all thread/job names used with `beast::setCurrentThreadName`, so the effective Linux thread name stays within the 15-character limit.
* Removes per-ledger sequence numbers from job/thread names to avoid long labels. This improves aggregation in lock contention profiling for short-lived job executions.
This change:
* Removes a set of unnecessary brackets in the initialization of an `std::uint32_t`.
* Fixes a couple of incorrect flags (same value, just wrong variables - so no amendment needed).
When `gateway_balances` gets called on an account that is involved in the `EscrowCreate` transaction (with MPT being escrowed), the method returns internal error. This change fixes this case by excluding the MPT type when totaling escrow amount.
This change introduces the `fixExpiredNFTokenOfferRemoval` amendment that allows expired offers to pass through `preclaim()` and be deleted in `doApply()`, following the same pattern used for expired credentials.
`PeerImp` processes `TMGetObjectByHash` queries with an unbounded per-request loop, which performs a `NodeStore` fetch and then appends retrieved data to the reply for each queried object without a local count cap or reply-byte budget. However, the `Nodestore` fetches are expensive when high in numbers, which might slow down the process overall. Hence this code change adds an upper cap on the response size.
This change:
* Truncates thread names if more than 15 chars with `snprintf`.
* Adds warnings for truncated thread names if `-DTRUNCATED_THREAD_NAME_LOGS=ON`.
* Add a static assert for string literals to stop compiling if > 15 chars.
* Shortens `Resource::Manager` to `Resource::Mngr` to fix the static assert failure.
* Updates `CurrentThreadName_test` unit test specifically for Linux to verify truncation.
If the config disables SQL db usage, such as a validator:
```
[ledger_tx_tables]
use_tx_tables = 0
```
then the pointer to DB engine is null, but it was still resolved during startup. Although it didn't crash in Release mode, possibly due to the compiler optimizing it away, it did crash in Debug mode. This change explicitly checks for the validity of the pointer and generates a runtime error if not set.
The `ledger_entry` and `deposit_preauth` requests require an array of credentials. However, the array size is not checked before is gets processing. This fix adds checks and return errors in case array size is too big.
This change fixes the `account_tx` RPC method to properly validate malformed limit parameter values. Previously, invalid values like `0`, `1.2`, `"10"`, `true`, `false`, `-1`, `[]`, `{}`, etc. were either accepted without errors or caused internal errors. Now all malformed values correctly return the `invalidParams` error.

- Refactor Number internals away from int64 to uint64 & a sign flag
- ctors and accessors return `rep`. Very few things expose
`internalrep`.
- An exception is "unchecked" and the new "normalized", which explicitly
take an internalrep. But with those special control flags, it's easier
to distinguish and control when they are used.
- For now, skip the larger mantissas in AMM transactions and tests
- Remove trailing zeros from scientific notation Number strings
- Update tests. This has the happy side effect of making some of the string
representations _more_ consistent between the small and large
mantissa ranges.
- Add semi-automatic rounding of STNumbers based on Asset types
- Create a new SField metadata enum, sMD_NeedsAsset, which indicates
the field should be associated with an Asset so it can be rounded.
- Add a new STTakesAsset intermediate class to handle the Asset
association to a derived ST class. Currently only used in STNumber,
but could be used by other types in the future.
- Add "associateAsset" which takes an SLE and an Asset, finds the
sMD_NeedsAsset fields, and associates the Asset to them. In the case
of STNumber, that both stores the Asset, and rounds the value
immediately.
- Transactors only need to add a call to associateAsset _after_ all of
the STNumbers have been set. Unfortunately, the inner workings of
STObject do not do the association correctly with uninitialized
fields.
- When serializing an STNumber that has an Asset, round it before
serializing.
- Add an override of roundToAsset, which rounds a Number value in place
to an Asset, but without any additional scale.
- Update and fix a bunch of Loan-related tests to accommodate the
expanded Number class.

- Fix overpayment asserts (#6084)
- MPTTester::operator() parameter should be std::int64_t
- Originally defined as uint64_t, but the testIssuerLoan() test called
it with a negative number, causing an overflow to a very large number
that in some circumstances could be silently cast back to an int64_t,
but might not be. I believe this is UB, and we don't want to rely on
that.
- Fix Overpayment Calculation (#6087)
- Adds additional unit tests to cover math calculations.
- Removes unused methods.
- Fix LoanBrokerSet debtMaximum limits (#6116)
- Fix some minor bugs in Lending Protocol (#6101)
- add nodiscard to unimpairLoan, and check result in LoanPay
- add a check to verify that issuer exists
- improve LoanManage error code for dust amounts
- In overpayment results, the management fee was being calculated twice:
once as part of the value change, and as part of the fees paid.
Exclude it from the value change.
- Round the initial total value computation upward, unless there is
0-interest.
- Rename getVaultScale to getAssetsTotalScale, and convert one incorrect
computation to use it.
- Use adjustImpreciseNumber for LossUnrealized.
- Add some logging to computeLoanProperties.
- Check permissions in LoanSet and LoanPay (#6108)

- Add a few minor changes (#6158)
- Updates or fixes a couple of things I noticed while reviewing changes
to the spec.
- Rename sfPreviousPaymentDate to sfPreviousPaymentDueDate.
- Make the vault asset cap check added in #6124 a little more robust:
1. Check in preflight if the vault is _already_ over the limit.
2. Prevent overflow when checking with the loan value. (Subtract
instead of adding, in case the values are near maxint. Both return
the same result. Also add a unit test so each case is covered.
- Add minimum grace period validation (#6133)
- Fix bugs: frozen pseudo-account, and FLC cutoff (#6170)
- Fixes LoanManage tfBAD_LEDGER case by capping the amount of FLC to use to cover a loss at the amount of cover available.
- Check if the Vault pseudo-account is frozen in LoanBrokerSet
- refactor: Rename raw state to theoretical state (#6187)
- Check if a withdrawal amount exceeds any applicable receiving limit. (#6117)
- Check the trust line limit is not exceeded for a withdraw to a third party Destination account.
- Fix test failures from interaction between #6120 and #6133
- LoanSet transaction added in #6120 failed the minimum grace period
added by #6133.
- Fix overpayment result calculation (#6195)

- Adds a mechanism for the vault owner to burn user shares when the vault is stuck. If the Vault has 0 AssetsAvailable and Total, the owner may submit a VaultClawback to reclaim the worthless fees, and thus allow the Vault to be deleted. The Amount must be left off (unless the owner is the asset issuer), specified as 0 Shares, or specified as the number of Shares held.
- Introduces amendment `fixBatchInnerSigs`
- Update Batch unit tests
- Fix all the Env instantiations to _use_ the "features" parameter.
- testInnerSubmitRPC runs with Batch enabled and disabled.
- Add a test to testInnerSubmitRPC for a correctly signed tx incorrectly
using the tfInnerBatchTxn flag.
- Generalize the submitAndValidate lambda in testInnerSubmitRPC.
- With the fix amendment, a transaction never reaches the transaction
engine (Transactor and derived classes.)
- Test submitting a pseudo-transaction. Stopped before reaching the
transaction engine, but with different errors.
- The tests verify that without the amendment, a transaction with
tfInnerBatchTxn is immediately rejected. Without the amendment, things
are safe. The amendment just makes things safer and more future-proof.
- Spec: XLS-66
- Introduces amendment "LendingProtocol", but leaves it UNSUPPORTED to
allow for standalone testing, future development work, and potential
bug fixes.
- AccountInfo RPC will indicate the type of pseudo-account when
appropriate.
- Refactors and improves several existing classes and functional areas,
including Number, STAmount, STObject, json_value, Asset, directory
handling, View helper functions, and unit test helpers.
This change fixes JSON parsing of negative `int` input in `STNumber` and `STAmount`. The conversion of JSON to `STNumber` or `STAmount` may trigger a condition where we negate smallest possible `int` value, which is undefined behaviour. We use a temporary storage as `int64_t` to avoid this bug. Note that this only affects RPC, because we do not parse JSON in the protocol layer, and hence no amendment is needed.
- Restructures `STTx` signature checking code to be able to handle
a `sigObject`, which may be the full transaction, or may be an object
field containing a separate signature. Either way, the `sigObject` can
be a single- or multi-sign signature.
- This is distinct from 550f90a75e (#5594), which changed the check in
Transactor, which validates whether a given account is allowed to sign
for the given transaction. This cryptographically checks the signature
validity.
This change fixes floating point errors in conversion of shares to assets and other way, used in `VaultDeposit`, `VaultWithdraw` and `VaultClawback`. In the floating point calculations the division introduces a larger error than multiplication. If we do division first, then the error introduced will be increased by the multiplication that follows, which is therefore the wrong order to perform these two operations. This change flips the order of arithmetic operations, which minimizes the error.
