… the nightly-pin report that hid it definitions.json had been synced for 3.3.0 and was eight fields behind develop, which definitions-watch reported as node-only for three weeks. The nightly-pin bump (#182) that would have listed them opened with an empty definitions section: the step inherits `bash -e` from the runner, the diff exits 1 whenever it finds drift, and errexit ended the step at the assignment before the report was echoed or recorded. - definitions.json: ContractResult, VaultKind, SubscriptionDate, RedemptionDate, IssuerKeyEpoch, AuditorKeyEpoch, IssuerKeyMirrorEpoch, AuditorKeyMirrorEpoch; Xrpl.BinaryCodec 11.1.0.0 - closed-ended vaults (rippled #7921, LendingProtocolV1_1): VaultKind, SubscriptionDate, RedemptionDate on VaultCreate and LOVault, the VaultKind enum, and rippled's preflight rules in ValidateVaultCreate - confidential MPT key rotation (rippled #7915): IssuerKeyEpoch and AuditorKeyEpoch on LOMPTokenIssuance; MPTokenIssuanceSet docs describe rotation - CredentialIDs on VaultWithdraw and LoanBrokerCoverWithdraw - transactions.macro fixture pinned to the same develop commit as ledger_entries.macro; the 3.3.0 tag no longer agrees with develop on fields - nightly-pin-watch: `set +e` before the diff so the report survives drift - guides: closed-ended vaults (Vault-Guide), key rotation (ConfidentialMPT-Guide) Verified: 1290 TestU pass; `GenerateEnums diff` against devnet (3.4.0-rc2) reports 0 node-only, down from 4; the nightly pin adds the four key-epoch fields on top, all covered by TestUDevelopFields_BinaryRoundTrip.
…he nightly stand TestIClosedEndedVault, gated on LendingProtocolV1_1: a closed-ended vault through its three phases (deposit in subscription; tecEXPIRED / tecTOO_SOON in investment; withdrawal in redemption), an open-ended vault carrying no VaultKind on the ledger, and a VaultWithdraw to a deposit-authorized destination that is tecNO_PERMISSION without CredentialIDs and succeeds with them. The run caught a wrong constant: kMinInvestmentPeriod is 180 s since rippled #8151, not the 60 s of the original #7921. ValidateVaultCreate, its unit test and the docs now say three minutes. Found on the same stand and left for a follow-up: under LendingProtocolV1_1 LoanBrokerSet refuses an open-ended vault, and the whole Loan integration suite builds on open-ended ones - 18/18 of TestILoan fail there, identically on untouched dev. The CI stand (3.3.0) is unaffected. Verified on xrpld 3.4.0-rc1 (the #182 pin): TestIClosedEndedVault 3/3, TestIVault and TestICredential 25/25; TestU 1290/1290.
…1 asks for it
Under the amendment LoanBrokerSet::preclaim refuses an open-ended vault
("LoanBroker requires a closed-ended Vault", tecNO_PERMISSION), and every Loan
test built its broker on one: 18 of 18 failed on the nightly stand, identically
on untouched dev.
TestILoanBase now creates a closed-ended vault when the node has the amendment
and waits for the investment phase before returning a broker. rippled originates
a loan only in that phase, and takes the vault deposit that funds it only in the
subscription phase before it, so the two dates are set from the ledger's close
time rather than the machine's clock. A node without the amendment does not know
the fields at all and answers invalidTransaction, so the open-ended path stays,
selected through AmendmentGuard.LendingProtocolV11.
The same helper now builds the vault in TestISponsoredVaultLoan, and the
close-time helpers move to IntegrationTestConfig, where three classes can share
one copy.
Verified on both stands. Nightly (xrpld 3.4.0-rc1): TestILoan 7 of 18, up from
0; every remaining failure is "Counterparty: Invalid signature", the role
signing prefixes of fixCleanup3_4_0, which is a separate change this branch does
not make. CI stand (3.3.0): TestILoan, TestIVault, TestIClosedEndedVault and
TestISponsoredVaultLoan pass 38 of 38, 3 skipped by amendment guard.

…s of their own rippled's fixCleanup3_4_0 gives each signing role its own four-byte hash prefix. Before it every signature on a transaction covered the same bytes, so one could be lifted out of SponsorSignature and pasted into CounterpartySignature, or into TxnSignature, and still verify. - HashPrefix gains the four role prefixes; EncodeForSigning and EncodeForMultiSigning gain overloads taking one. The transaction's own prefixes are untouched, so an ordinary signature is byte-for-byte what it was - the role is not something a caller states: it follows from the method, and for a multi-signature entry from the shape of the transaction. The one ambiguous shape, where the main signature and a co-signature are both multi-signed, gets Sign(tx, multisign, signingFor, SignatureRole) - multi-signature entries are no longer portable between sections, so the composer's premise is documented as the pre-amendment rule it was - the older scheme is not carried and nothing asks the node which one it wants: no public network has Sponsor or LendingProtocol without the amendment Breaking against a private node on a release older than the amendment that has Sponsor or LendingProtocol voted in. That is what this repository's CI stand is, so the integration tests producing a role signature now skip there through AmendmentGuard: 346 integration tests passed on that stand before, 286 pass and 63 skip now. All of them run on the nightly stand. Verified. Unit: 1294 pass, including prefixes checked against rippled's own makeHashPrefix tags and a preimage that differs from the transaction's in four bytes and nothing else. Nightly stand (xrpld 3.4.0-rc1): 87 of 87 across TestILoan, TestILoanMultisig, the sponsorship classes, TestIXChainAttestation and the vault classes, where before every role signature was refused with "Invalid signature". CI stand (3.3.0): 286 pass, 63 skip, 0 fail. Two rules of the same amendment surfaced once the tests could reach them and are handled in the tests: a loan may only be impaired once a payment is late, and a payment on an overdue loan must carry tfLoanLatePayment or it is tecEXPIRED.

…nd a typed role overload From the CodeRabbit review of #183, four findings, all confirmed against the code. - nightly-pin-watch: the diff tool exits 2 when it cannot run at all, and the grep then found nothing and reported "no differences reported" to the PR body - the reassuring answer for the one case that has no answer. Only 0 and 1 are read as a verdict now; anything else says the diff did not run, and carries the output. The step stays informational and still opens the PR: a diff tool that fell over is not a reason to withhold a pin bump, which is what the step's own comment says and why the reviewer's second suggestion is not taken - XrplWallet: a typed Sign overload carrying the role, so a caller holding an ITransactionRequest does not have to convert to a dictionary to sign as a sponsor or a counterparty in the one ambiguous shape - XrplWallet: the sponsor XML doc said the sponsor signs "the sponsor preimage the submitter signs", a sentence left half-rewritten when the preimages parted - CHANGES: the vault entry described the signature failures as something this release does not implement, while the entry above it implements them. It now reads as the intermediate result it was, and its stale CI-stand count is gone - the signing entry carries the measurement that survived Unit suite 1294 pass; the workflow parses.
…ships From a cold review of this branch: three reviewers on two models, one pass, none of them told what the change was for. Eleven findings survived verification. The two the models found independently are one defect seen from both ends. Where the main signature is multi-signed as well, the transaction cannot say which side a multi-signature entry belongs to; the signer chose the transaction's own prefix whatever the answer, and the composer routed the entry by account without noticing. The role parameter added for that shape did not close it either: it corrected the prefix while the preimage kept a SigningPubKey the composed transaction does not ship. - SignatureComposer verifies every signature in the finished transaction against the bytes that transaction ships, under the prefix of the section the signature landed in, and names the account and the section when one does not verify. It found two mis-signed compositions in this repository's own unit tests - a multi-signature entry with SignatureRole.Transaction on a transaction that has a single main signature is a contradiction and is refused - the role overload no longer skips the Batch inner-signer routing, and no longer discards an explicit transaction role into the co-signature path - SponsorSigningHelper.GetSigningPreimage is now GetSponsorPreimage: the name returned both signatures' bytes while they were the same, and keeping it would have changed what a call means without changing how it compiles Two of the findings are about how this branch was verified, and one of them is the sharper. TestClosedEndedVault_Phases waited 180 s for the redemption phase under a 120 s budget: it had passed only because the earlier runs were parallel and the load ate the wait. Run alone it fails, short by 56 s. The budget now follows the distance to the mark. The subscription window goes to 30 s, the value the sibling helper already justifies. - the role-signature guard moved off the sponsorship classes onto the tests that actually make one, giving the CI stand back its three SponsorshipSet tests - the nightly-pin workflow no longer puts raw tool output into a step output that a later step pastes into its own shell source: a substituted $(id -u) executed - the prefix test reads rippled's HashPrefix.h, vendored as a fixture, instead of restating the constants it was meant to check Verified. Unit 1294 pass. Nightly stand (xrpld 3.4.0-rc1) 87 of 87, and the phase test alone 3 m 30 s. CI stand (3.3.0) 289 pass, 60 skip, 0 fail, up from 286/63.
From a second opinion by another model on the signing subsystem, given the diff and nothing else. The role-aware overload dropped the role it exists to carry. Fixing the earlier finding that it skipped the Batch inner-signer routing, it delegated to the overload that has no role parameter - which then inferred the side from the transaction. On a sponsored transaction with a single main signature, a caller asking for the transaction's own entry got a sponsor-side one, with no error, and the guard written for exactly that contradiction was unreachable through the public API. The routing is now a private method both overloads share, and the role travels through it. - SponsorSigningHelper.GetSigningPreimage comes back as a member that refuses: [Obsolete(error: true)] plus a throw. Deleted outright it was MissingMethodException for a consumer built against the old assembly and "no such member" for one rebuilding; kept and returning the sponsor's bytes it would have compiled and produced signatures the node refuses - two XML comments promised that a caller must state the role where the main signature is multi-signed as well. The code takes the entry as the transaction's own there, which is the common case, and the composer catches a wrong choice. The comments now say what the code does Pinned by a test that fails on the previous code: a stated Transaction role on a sponsored transaction with a single main signature is refused rather than answered with a sponsor entry, and on a multi-signed one it produces an entry that verifies under the transaction's own prefix. Unit suite 1295 pass.
The renamed method is removed outright rather than kept as an [Obsolete] member that throws. That stub was out of step with this repository's own policy, stated twice in the changelog for earlier breaks: no [Obsolete] bridges. A member that refuses is still a member on the public surface, and the compile error a removal gives is the migration notice. Unit suite 1295 pass; no caller of the old name remains.
…fusal is not an answer
Second opinion from another model on the parts of this branch it had not seen:
the integration tests, the guards and the nightly-pin workflow.
The workflow finding is the same defect twice, and the second half was mine. Its
verdict was the exit code of `dotnet run`, which answers 1 both for drift and for
a build that never produced a diff, so a failed build with no matching output
still reached the PR body as "no differences reported". The verdict is now the
tool's own Summary line: no Summary, no answer. And the comment claiming the
output "stays text this file chose" was false for the whole success branch - the
matched lines carry field names the node chose. Every step output now reaches the
PR body through the environment instead of a ${{ }} pasted into the shell source,
which also closes the same hole on the two amendment lists that predate this
branch.
- both amendment guards cached a negative. IsEnabledAsync answers false for "the
node does not have it" and for "the node refused the question" alike, so one
transient error made a whole run report as skipped, or sent every later broker
to the open-ended path the amendment refuses. Only a yes is remembered now
- EnterInvestmentPhaseAsync treated a ledger_entry that came back as anything
else as an open-ended vault and skipped the wait. It now says so
- past the subscription date is not the same as inside the investment phase.
Overshooting into redemption made the LoanSet that follows fail with
tecEXPIRED, reading as a protocol refusal rather than a missed window; the
phase test would have reported it as its own tecTOO_SOON assertion failing.
Both now check the upper bound and say which happened
- the comment on the subscription window described time left after the vault
exists; the clock starts at the close-time read before it
Not changed, with the reason: adding a member to IVaultCreate, IVaultWithdraw and
ILoanBrokerCoverWithdraw does break an outside implementation of those
interfaces, and that is in CHANGES now. A default body is not the fix - on a data
contract it would have to accept a value and drop it. The claim that
WaitForCloseTimeAsync can wait forever does not hold either: the client's
RequestTimeout is 40 s, so a silent node ends the wait with its own exception;
the budget can be overshot by one request, and the remark now says so.
Verified. Unit 1295. Nightly stand (xrpld 3.4.0-rc1) 87 of 87. CI stand (3.3.0)
289 pass, 60 skip, 0 fail.

…ping today 11.4.0.0 is being published from dev today, so the entries written under that heading move to their own section and the two packages this branch changes go with them. The 11.4.0.0 section is byte-identical to dev's again, checked rather than eyeballed. Xrpl and Xrpl.BinaryCodec take the same number, as they do whenever both move. Xrpl.AddressCodec and Xrpl.Keypairs are untouched here and stay at 10.9.0.0.

The three watchers fired on the same event this week: rippled develop moved on while
definitions.jsonwas still at 3.3.0.

Under LendingProtocolV1_1LoanBrokerSetrefuses an open-ended vault ("LoanBroker requires a closed-ended Vault"), and the Loan suite builds every broker on an open-ended one. The CI stand (3.3.0) is unaffected; before the CI stand moves to a release carrying the amendment,TestILoanBasehas to create closed-ended vaults and place the loan flow in the investment phase. Recorded in CHANGES as a follow-up.Follow-up landed in this branch: the Loan suite under LendingProtocolV1_1
The
TestILoanfailure reported above is fixed rather than left.TestILoanBasenow creates a closed-ended vault where the node asks for one and waits for the investment phase before returning a broker: rippled originates a loan only there, and takes the vault deposit that funds it only in the subscription phase before it. The phase dates come from the ledger's close time, not the machine's clock. A node without the amendment does not know the fields and answersinvalidTransaction, so the open-ended path stays, selected throughAmendmentGuard. The same helper builds the vault inTestISponsoredVaultLoan, and the close-time helpers move toIntegrationTestConfigso three classes stop carrying their own copies.Measured on the two stands:

Invalid signaturewall reported above is gone: this branch now signs role signatures the way the amendment requires. Before it, the submitter'sTxnSignature, the sponsor'sSponsorSignatureand the borrower'sCounterpartySignatureall covered the same bytes, so a signature could be moved between roles and still verify. rippled gives each role its own four-byte hash prefix.HashPrefixgains the four role values;EncodeForSigningandEncodeForMultiSigninggain overloads taking a prefix. The transaction's own prefixes are untouched, so an ordinary signature, single or multisig or Batch, is byte-for-byte what it was.Sign(tx, multisign, signingFor, SignatureRole.Sponsor)says it.SponsororLendingProtocolenabled withoutfixCleanup3_4_0: on mainnet and testnet none of the three is on, on devnet all three are.The cost, measured. The one place the old combination exists is this repository's CI stand, a 3.3.0 image with
SponsorandLendingProtocolvoted in at genesis. Integration tests producing a role signature now skip there throughAmendmentGuardand run on the nightly stand.TestISixty of the 63 skips are tests that used to pass on the CI stand; the other three are the closed-ended vault tests this branch adds. The guard turns them back on by itself once the CI stand moves to a release carrying the amendment.
How the prefixes are checked without a node. A pinned blob cannot answer whether a preimage is right, since regenerating it from the same code only agrees with itself. The new unit tests check the prefixes against rippled's own
makeHashPrefixtags and assert that a role preimage is the transaction's preimage with four bytes changed and nothing else. The node settles the rest.Two rules of the same amendment surfaced once the tests could reach them, and are handled in the tests rather than the SDK: a loan may only be impaired once a payment is actually late, and a payment on an overdue loan must carry
tfLoanLatePaymentor it istecEXPIRED.Order
Independent of #182 (no overlapping files). Merging #182 first makes definitions-watch compare against the build this PR describes.
