The integration suite could only ever run against the local standalone stand: every TestI* class hard-coded TestNodeType.Standalone and the genesis account for funding, so XRPL_TEST_NODE selected nothing. Pointing it at devnet found four defects, two of them in the library, and closed 49 red cells on the XRPL Foundation amendment dashboard along the way.

Library fixes

FundWallet worked only a few times per process. The faucet helper polled for the funded balance through a System.Timers.Timer driven by static fields, and the poll budget was initialised once and never reset. It bought twenty polls for the lifetime of the process: the first few wallets were funded, and every call after that reported Unable to fund address with faucet after waiting 1 * 20 seconds without polling at all. Anyone funding a second wallet on testnet or devnet hit this. The concurrent case was worse: two overlapping calls overwrote each other's address and result, so a caller could be handed another wallet's balance and treat an unfunded wallet as funded. All of that state belongs to the call now, and the async void timer callback whose exception the caller could not catch is gone.

Reading a ledger failed on an Oracle holding bytes we would not have written. The converters for Provider, AssetClass, URI and for a nonstandard currency code required the decoded bytes to be printable ASCII. rippled imposes no such rule: OracleSet::preflight checks length and nothing else, and a currency code is 160 unconstrained bits. Because the check ran inside a JsonConverter it did not fail one field, it threw out of the whole response, so a single third-party oracle in a ledger_data page made the page unreadable. Reading is total now; writing still requires text.

A Batch with one inner transaction is refused locally. rippled Batch::preflight answers temARRAY_EMPTY to fewer than two inners, the same code as for none at all, while ValidateBatch only refused an empty RawTransactions.

ComposeSignatures keeps its two-argument form. Counterparty routing needed a third argument; giving it a default would have been source-compatible but not binary-compatible.

New capabilities

Multisig counterparty for LoanSet (XLS-66). CounterpartySignature accepts the multisig form, which rippled checks against the counterparty's SignerList over the same multisign preimage as tx.Signers, but nothing in the SDK could produce it: a borrower with a SignerList could not co-sign a loan at all. Each signer of the borrower's list now signs with the standard Sign(tx, multisign: true), and ComposeSignatures routes the entries by looking that SignerList up alongside the Account's and the Sponsor's, pre-checking the quorum by weight.

Witness-side attestation signing (XLS-38). XChainAddClaimAttestation and XChainAddAccountCreateAttestation were modelled but nothing could fill their PublicKey and Signature, so a witness server could not be written on this SDK. XChainAttestationSigner builds the signed message from the attestation's own fields and verifies a received one the way attestationPreflight does. The byte layout is pinned field by field from the XRPL binary format, independent of the SDK's codec.

Tests that reported success without proof

Utils.TestTransaction verified nothing. The helper behind about forty of the older tests looked the submitted transaction up once and discarded the response without asserting anything. It read as a verification step and was not one.

The 18 Batch tests asserted on the engine result, which is provisional, and accepted terQUEUED, which says the transaction was not applied at all. A batch that never reached a ledger passed.

TestILedgerStateFix submitted with fail_hard, which drops a tec from the open ledger, so its result never reached a validated ledger.

Four classes derived their accounts from a fixed phrase. A phrase is the same account on every network, so on a public one it is shared with everyone who ever ran the same test, and two of those classes disable a master key on one. It bit on the stand too: a derived account kept its state between runs, so five DID tests each created a DID an earlier run had already created.

Test infrastructure

The node comes from the environment now: XRPL_TEST_NODE picks the funding policy, XRPL_TEST_NODE_URL the WebSocket URL, XRPL_TEST_ADMIN_AUTH_URL the admin port. Faucet funding retries, tops an account up when one payout is not enough, and is no longer fully serialised. A public endpoint is a cluster, so tests that open a second connection wait for their account to be visible there. Two classes are standalone-only by construction and say so instead of failing.

AMM, AMMClawback, MPTokensV1 and XChainBridge classes are gated by AmendmentGuard like the others. Three matrix classes exercise the transaction surface end to end: every type as a Batch inner read back by its computed id, the Sponsor field on every type other than Payment, and every AMM transaction over an MPT asset. devnet-coverage.yml (manual dispatch, never CI) runs them against devnet.

Protocol facts the runs surfaced, written down where the tests live: a DID entry carries no Sponsor field, so spfSponsorReserve on DIDSet is temINVALID_FLAG; the Sponsorship entry lands in the sponsee's owner directory, so asfAllowTrustLineClawback must precede it; a time gate in rippled is now > mark, so a wait that stops on equality is a tick early; and an outer Batch validating with tesSUCCESS does not mean its inners applied, because tfAllOrNothing discards the whole view while Batch::doApply still returns success.

Verification

Full CI on this branch, all green, nothing skipped: 1238 unit, 329 integration on the standalone stand, 6 x402.

Against devnet, every integration class was run in batches: 236 passed, 12 skipped, none failed. The skips are nine MPT-in-AMM tests (MPTokensV2 is not on devnet), the two admin-port tests and account deletion.

Dashboard movement measured before and after: Sponsor 45/107 to 84/107, XChainBridge 14/40 to 23/40, LendingProtocol 65/73 to 66/73.

Xrpl moves to 11.3.0.0. The base packages are untouched.

Every TestI* class hard-coded TestNodeType.Standalone and the genesis account
for funding, so XRPL_TEST_NODE selected nothing and the suite could only ever
run against the local stand. The profile now comes from the environment:
XRPL_TEST_NODE picks the funding policy and whether ledger_accept is issued,
XRPL_TEST_NODE_URL overrides the WebSocket URL (a stand on other ports, a
private node), and public networks fund wallets straight from the faucet with
retries instead of through a 10 XRP filler.

AMM, AMMClawback, MPTokensV1 and XChainBridge classes are gated by
AmendmentGuard like the others, so they skip on a network without the
amendment instead of failing.

TestILedgerStateFix submitted with fail_hard, which drops a tec result from the
open ledger: its tecFAILED_PROCESSING never reached a validated ledger and
proved nothing. It now goes in without the flag.

devnet-coverage.yml (manual dispatch, never CI) runs the coverage-oriented
classes against devnet, where the XRPL Foundation amendment dashboard scores
each amendment by the validated transactions that exercised its surface.
rippled Batch::preflight answers temARRAY_EMPTY to fewer than two inners - the
same code as for none at all - while ValidateBatch only refused an empty
RawTransactions. Five of sixteen inner-type batches failed on the stand that
way before the rule was found. The validation now says what the node would:
at least two, at most eight.
Three classes exercise the SDK's transaction surface end to end rather than
one feature at a time: every transaction type as a Batch inner, read back by
its computed id (TestIBatchInnerTypes); the Sponsor field on every transaction
type other than Payment, sponsor co-signing (TestISponsoredTypes); every AMM
transaction type over an MPT asset, including the lsfMPTAMM entry flag on the
pool account (TestIAMMMpt, formerly TestIAMMCreateMpt, which covered AMMCreate
only).

Two protocol facts the matrices surfaced are written down where the tests
live: a DID entry carries no Sponsor field, so spfSponsorReserve on DIDSet is
temINVALID_FLAG; and the Sponsorship entry lands in the sponsee's owner
directory too, so asfAllowTrustLineClawback must be set before the sponsorship
exists.
CounterpartySignature (XLS-66) accepts the multisig form - an empty
SigningPubKey and a Signers array that rippled checks against the
counterparty's SignerList over the same multisign preimage as tx.Signers
(STTx::checkMultiSign with the inner object) - but nothing in the SDK could
produce it. Each signer of the borrower's list now signs with the standard
Sign(tx, multisign: true), and the composer places the entries:
IXrplClient.ComposeSignatures looks the Counterparty's SignerList up alongside
the Account's and the Sponsor's and pre-checks the quorum by weight;
SignatureComposer.ComposeSignatures takes counterpartySignerAccounts for the
offline case, with LoanSigningHelper.CombineLoanSignatures as the
LoanSet-shaped entry.

The fee has to cover the signers (LoanSet::calculateBaseFee charges one base
fee per entry), so the flow autofills with signersCount before anyone signs.
Pinned on the standalone node: a 2-of-2 borrower, ledger-routed and offline
composition, and the below-quorum refusal.
XChainAddClaimAttestation and XChainAddAccountCreateAttestation were modelled
but nothing could fill their PublicKey and Signature: a witness signs the
canonical serialization of an STObject holding the attested facts, with no
hash prefix and no transaction fields (rippled AttestationClaim::message /
AttestationCreateAccount::message). XChainAttestationSigner builds those
bytes from the attestation transaction's own fields, signs them with the
witness wallet, and verifies a received attestation the way
attestationPreflight does.

The byte layout is pinned field by field from the XRPL binary format,
independent of the SDK's codec: the order rippled assigns is the canonical
sort order, so a codec regression on STXChainBridge or on field ordering fails
in the unit test rather than as temXCHAIN_BAD_PROOF on a node.

The whole witness half runs against one standalone node: rippled resolves a
bridge spec to the locking-side entry first, so with only that entry on the
ledger a commit locks funds in the door and an attestation with
WasLockingChainSend = 0 releases them here - delivery on quorum with a
Destination, an explicit XChainClaim with a DestinationTag without one, an
unlisted witness refused with tecNO_PERMISSION, and account creation reaching
quorum across two witnesses through an XChainOwnedCreateAccountClaimID.
The faucet helper polled for the funded balance through a System.Timers.Timer
driven by static fields - the poll budget, the address, the two balances and
the result - and the budget was initialised once and never reset. It bought
twenty polls for the lifetime of the process: the first few wallets were
funded, and from then on every call reported "Unable to fund address with
faucet after waiting 1 * 20 seconds" without polling at all. Anyone funding a
second wallet on testnet or devnet hit this, which is every integration suite
and most tutorials.

The concurrent case was the dangerous half. Two overlapping calls overwrote
each other's address and result, so a caller could be handed another wallet's
balance and treat an unfunded wallet as funded. All of that state now belongs
to the call.

The timer went with it. Its callback was async void, so the exception it
raised on giving up could not be caught by the caller, and the wait loop
blocked its thread on Task.Delay(...).Wait() inside an async method.

The balance was also polled twice per wallet: the faucet answers with the
destination account, so the second poll re-read an address that had just been
read.

Found by running the integration suite against devnet, where the standalone
stand never calls the faucet: 21 of 22 sponsored-type tests failed on it.
Verified the same way - one process, some sixty faucet calls, all funded. The
faucet call news up its own HttpClient, so the helper cannot be exercised
without the network and there is no unit test for it.

The test project carried a verbatim copy of the broken timer as dead,
commented-out scaffolding; left in place it invites the pattern back.
A public faucet hands out a fixed 100 XRP per call, less than a single account
needs in some flows: a lending broker funds a 100 XRP vault and a 50 XRP
cover, so CreateBroker could never succeed on devnet. EnsureBalanceAsync tops
an account up to a stated minimum by calling the faucet again; on the
standalone stand the master payment covers any realistic minimum and it
returns after the first check.
…hrase

Four classes built their wallets with XrplWallet.FromNormalizedText("primary
test account") and the like. A phrase is the same account on every network, so
on a public one it is shared with everyone who ever ran the same test: the
state a test starts from is whatever they left behind, and TestIBatch and
TestIMultisign disable a master key on one of those accounts. That made the
four classes unusable outside the standalone stand.

It bit on the stand too. A derived account kept its state between runs, so the
five DID tests each created a DID that an earlier run had already created, and
the assertion that the DID exists afterwards passed either way. The create
path was never actually exercised after the first run.

TestIDID folds the generate-and-fund pair into one helper, since it repeated
in every test.
Reading an inner batch transaction back by its computed id is a poll, not a
single call. The outer Batch is validated by the time the lookup runs and its
inners were applied in the same ledger, but the node answers txnNotFound for a
short window before they are queryable, which made the class fail
intermittently under a parallel load. Exhausting the budget now says which
inner never appeared and what the two explanations are.
… result

The 18 Batch tests checked the engine result of their submission. That is
provisional: it says what one node made of the transaction against its open
ledger, not what the network settled on, and they also accepted terQUEUED,
which says the transaction was not applied at all. A batch that never reached
a ledger passed.

They now wait for the transaction to appear in a ledger and check the result
recorded there. That also settles the account sequences between tests: the old
assertion returned before the submission was applied, so the next test
autofilled against a ledger that did not yet carry it and got tefPAST_SEQ.
That is how this surfaced when the class was first run against devnet.

The unused TransactionSummary overload goes with it.
A time gate in rippled is `now > mark`, not `now >= mark` (after() in
View.cpp), so a wait that stops on equality is still a tick early. The escrow
case waited that way and its EscrowCancel inner came in one close time short.
Under tfAllOrNothing that reverts the whole batch, so the sibling EscrowFinish
was never committed either and the lookup for it failed with no sign of the
real cause. Standalone close times move in coarse steps and land on equality
readily; devnet's next step arrived within seconds and hid it.

The settle batch is tfIndependent now, where each inner records its own
result, and a missing inner says what tfAllOrNothing does to a batch with a
failing sibling: rippled discards the whole view, no inner is committed, the
failing inner's result is recorded nowhere, and the outer Batch still
validates with tesSUCCESS.
The converters for an Oracle's Provider, AssetClass and URI, and for a
nonstandard currency code, required the decoded bytes to be printable ASCII
and threw a JsonException otherwise. rippled imposes no such rule:
OracleSet::preflight checks the length of those fields and nothing else, so
they are Blob fields carrying arbitrary bytes, and a currency code is 160 bits
the ledger does not constrain either.

Because the check ran inside a JsonConverter it did not fail one field, it
threw out of the whole response: a single third-party oracle in a ledger_data
page made the page unreadable. Found by running the suite against devnet,
where other people's oracles exist; the standalone stand only ever holds ours.

Reading is total now. Bytes that are text are decoded, anything else comes
back as the hex the node sent. Writing still requires printable ASCII, so a
value that came back as hex is not something to hand straight back.

The test that pinned the old behaviour asserted the throw; it now asserts the
value survives, alongside one for a nonstandard currency code.
The helper behind about forty of the older integration tests looked the
submitted transaction up once, immediately after submission, and discarded the
response without asserting anything about it. It read as a verification step
and was not one. On the standalone stand the caller had just forced a ledger
close so the lookup happened to find something; on any network where ledgers
close on their own it raced. It waits for the transaction to reach a ledger
now and checks the result recorded there.

Two classes are standalone-only by construction and say so instead of failing
on a public network: TestIAdminCredentials needs the stand's own
[port_ws_admin_auth], and TestIAccountDelete forces the 256 ledger closes
rippled requires before an account can be deleted.

The two check tests carried a 60s budget sized for a stand where funding is a
local payment and the test forces the ledger to close. Raised for a public
network, where funding comes from a serialised faucet and the ledger closes on
its own.
A public endpoint is a cluster behind one name, so an account funded over one
connection may not be visible on a second one yet. The path-finding tests are
the only ones that open a second client, and they hit srcActNotFound on it
intermittently on devnet; they wait for the account there now.

Faucet calls are no longer fully serialised either. The limit of one dated
from a shared filler wallet whose sequence could not take concurrency; each
call now funds its own destination and shares nothing. Serialising them spent
minutes that individual tests were charged for inside their own timeouts, and
six path tests timed out on the queue rather than on anything they did. The
same batch now finishes in half the time.
Counterparty routing needed a third argument, and it was added with a default.
That is source-compatible but not binary-compatible: an assembly compiled
against the two-argument signature emits a call to a method that would no
longer exist in the package, so it fails at run time rather than at build.
Both forms are now declared and both are pinned.

DecodeOracleCurrency stopped at the first zero byte without checking that the
rest were zero, so 5553440001... read as "USD" and would have lost the 0x01 on
the way back out, and twenty zero bytes read as an empty string. Both come
back as the hex the node sent now.

Raised in review of #165.
VerifyClaimAttestation and VerifyAccountCreateAttestation reconstruct the
message and check the signature. They say nothing about whether the key may
speak for AttestationSignerAccount or whether that account is on the door's
SignerList; rippled decides both at preclaim and needs a ledger to do it.

Raised in review of #165.
A seed no longer travels to a node someone else runs. TestIMemoLimits hears
rippled refuse an over-length memo, and to hear it the node has to sign the
transaction, because the SDK's own rules stop it first. Node-side signing puts
the wallet's seed on the wire, which was fine while the only reachable node
was on this machine. It is standalone-only now; the rule it checks is
rippled's and does not vary by network.

TestChangeServer_SwitchesSuccessfully skips rather than asserting a switch
that did not happen: the alternate endpoint is the same URL with localhost
spelled as 127.0.0.1, which is no alternate at all for an address that does
not say localhost.

The faucet host is named from the profile instead of inferred from the
connection URL, which throws when it recognises nothing: XRPL_TEST_NODE_URL
may point at a node whose hostname says nothing about which network it is on.

The sponsored escrow test waits for a close time strictly past its mark, the
same one-tick error already fixed in the batch matrix.

Every second-client path in the path-finding tests waits for its account, not
just the three that had it. And path-finding requests retry while the node
answers srcActNotFound: rippled answers them from a ledger snapshot of its own
that can lag the validated ledger funding confirmed the account on.

Raised in review of #165, except the last, which that fix surfaced.

Review findings

All seven are addressed, none rejected. Six were posted inline and answered on their threads; this covers the one in the collapsed Outside diff range section, plus one that fixing it surfaced.

pathFind.cs 193, second-client visibility. Correct, and it was three sites, not one: TestPathFindStreamReceivesMultipleUpdates through streamClient, and the two negative-amount tests through pfClient. I had added the wait to three of six. All six wait now.

What that uncovered. With every second-client path waiting, TestIRipplePathFind.TestRequestWithSourceCurrencies still answered srcActNotFound on devnet, and it uses a single client for both funding and the request. Funding confirms the account on the validated ledger, so the account plainly existed. rippled answers path finding from a ledger snapshot it keeps for that purpose, and that snapshot can lag the validated ledger, so a freshly created source is missing from path finding for a few ledgers after it exists. Path-finding requests now retry while the node says srcActNotFound. The standalone stand closes ledgers on demand and never shows this.

Verification. Head is 75cfa6f7.

Run Result
Standalone stand, full TestI 329 of 329
Unit 1238 of 1238
devnet, affected classes 47 passed, 2 skipped, 0 failed
devnet, path-finding classes, twice 12 of 12 both times

The two devnet skips are the two guards added in response to this review: node-side signing in TestIMemoLimits, and the server switch with no distinct endpoint to switch to.

WaitForCloseTimeAsync and ValidatedCloseTimeAsync, to enforce a finite timeout
or cancellation path when validated ledger time stops advancing; when the

Both copies of WaitForCloseTimeAsync polled without a deadline. A ledger that
stops advancing is a node failure, and a test that waits on it forever reports
nothing about it. The failure now names the last close time seen and how far
short of the mark it was, which separates a stalled node from a mark set too
far ahead. TestIEscrow already bounded its own copy this way.

Raised in review of #165.
