…tions Transaction#transactionFlags() resolves flags() reflectively. Pseudo-transactions lacked it, so checkSponsorshipFields() hit NoSuchMethodException and logged an error on every construction. Override flags() to return TransactionFlags.EMPTY. Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>

flags() defaults to EMPTY but nonzero values (tfGotMajority 0x10000, tfLostMajority 0x20000) from deserialized EnableAmendment transactions are preserved. Update Javadoc and add round-trip tests. Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>
EnableAmendment is the one pseudo-transaction with type-specific flags
(tfGotMajority = 0x00010000, tfLostMajority = 0x00020000), so give it a
dedicated EnableAmendmentFlags class following the existing typed-flags
convention instead of asking callers to compare raw values. The class has
no builder because these pseudo-transactions are ledger-emitted only.
xrpld signals "amendment enabled" by setting neither majority flag, which
is a non-obvious encoding; EnableAmendmentFlags.isEnabled() encapsulates it.
Also reword the flags() Javadoc on the three pseudo-transactions: fix the
"{@link TransactionFlags}s" typo, describe the three EnableAmendment status
transitions explicitly, and replace "pseudo-transactions have no defined
flags" (untrue for EnableAmendment) with a per-type statement.

Before the pseudo-transactions declared flags(), transactionFlags() always fell back to EMPTY for them, so RawTransactionWrapper.check() could never pass. Now that they carry real flags, a caller could set tfInnerBatchTxn on an EnableAmendment/SetFee/UnlModify and wrap it in a Batch. xrpld rejects pseudo-transactions from users regardless, but Batch already mirrors the inner-transaction preflight at construction time, so make the type policy explicit rather than relying on the flag value. Adds Transaction.PSEUDO_TRANSACTION_TYPES next to the existing RESERVE_SPONSOR_ALLOWED_TYPES allow-list, checked before the tfInnerBatchTxn check in RawTransactionWrapper.check().

This MR adds flags() to UnlModify, SetFee, and EnableAmendment (fixing the previously-thrown NoSuchMethodException via reflection), introduces a typed EnableAmendmentFlags class with the non-obvious isEnabled() encoding, and adds a Batch/RawTransactionWrapper guard rejecting pseudo-transaction types regardless of flags. The implementation follows existing conventions precisely (Value.Default + JsonProperty("Flags") pattern matching other typed flags classes like NfTokenOfferFlags), the flag bit values (0x00010000L/0x00020000L) match rippled and are properly L-suffixed, the PSEUDO_TRANSACTION_TYPES guard is correctly checked before the flag check in RawTransactionWrapper.check(), and test coverage (JSON round-trip, unknownFields exclusion, majority-flag preservation, and precondition asserting the flag check alone would have passed) is thorough. I did not find any correctness, security, or convention-violation issues in the changed lines worth flagging.

This diff adds flags() accessors to the three pseudo-transaction types (EnableAmendment, SetFee, UnlModify) that previously lacked them, introduces a typed EnableAmendmentFlags class for EnableAmendment's majority flags, and adds a pseudo-transaction guard to RawTransactionWrapper.check(). The implementation is consistent with existing Flags-subclass conventions in the repo (private constructors + of()/empty() factories, @JsonProperty("Flags") + @Value.Default on flags()), the isEnabled() encoding matches the documented rippled behavior, and the new PSEUDO_TRANSACTION_TYPES check in RawTransactionWrapper correctly precedes the tfInnerBatchTxn check. Test coverage (EnableAmendmentFlagsTest, updated EnableAmendmentTest/SetFeeTest/UnlModifyTest, and the new parameterized RawTransactionWrapperTest cases) exercises round-trips, constant values against rippled, and the new guard with a precondition proving the flag check alone would have passed. I did not find any correctness, security, or convention issues in the added/changed lines that meet the confidence bar for this review.

Check the concrete transaction type.
Transaction.transactionType() is an overridable @Value.Default in Transaction.java at Lines 156–160. A caller can build an EnableAmendment with .transactionType(TransactionType.PAYMENT) and tfInnerBatchTxn set. The membership check then accepts that pseudo-transaction as an inner transaction. Classify rawTransaction() by its concrete subtype instead, and test this mismatched-type case.
