- Implement injectEntropyPseudoTx() to combine reveals into final
entropy hash and inject as pseudo-tx into CanonicalTXSet in doAccept()
- Modify BuildLedger applyTransactions() to apply entropy tx FIRST
before all other transactions to prevent front-running
- Remove redundant explicit threading in applyConsensusEntropy() as
sfPreviousTxnID/sfPreviousTxnLgrSeq are set automatically by
ApplyStateTable::threadItem()
- Register ttCONSENSUS_ENTROPY in applySteps.cpp dispatch tables
(preflight, preclaim, calculateBaseFee, apply)
- Add ltCONSENSUS_ENTROPY to InvariantCheck.cpp valid type whitelist
Add protocol definitions for consensus-derived entropy pseudo-transaction:
- ttCONSENSUS_ENTROPY = 105 transaction type
- ltCONSENSUS_ENTROPY = 0x0058 ledger entry type
- keylet::consensusEntropy() singleton keylet (namespace 'X')
- applyConsensusEntropy() handler in Change.cpp
- Added to isPseudoTx() in STTx.cpp
The entropy value is stored in sfDigest field of the singleton ledger object.
This provides the protocol foundation for same-ledger entropy injection.
- Add clearRngState() call in startRoundInternal
- Reset estState_ in closeLedger when entering establish phase
- Implement three-phase RNG checkpoint gating:
- ConvergingTx: wait for quorum commits, build commitSet
- ConvergingCommit: reveal entropy, transition immediately
- ConvergingReveal: wait for reveals or timeout, build entropySet
- Use if constexpr for test framework compatibility
- Serialize full ExtendedPosition in share() and propose()
- Deserialize ExtendedPosition in PeerImp using fromSerialIter()
- Add harvestRngData() to collect commits/reveals from peer proposals
- Conditionally call harvest via if constexpr for test compatibility
Introduce data structures for consensus-derived randomness using
commit-reveal scheme:
- Add ExtendedPosition struct with consensus targets (txSetHash,
commitSetHash, entropySetHash) and pipelined leaves (myCommitment,
myReveal)
- operator== excludes leaves to allow convergence with unique leaves
- add() includes ALL fields to prevent signature stripping attacks
- Add EstablishState enum for sub-phases: ConvergingTx, ConvergingCommit,
ConvergingReveal
- Update Consensus template to use Adaptor::Position_t
- Add Position_t typedef to RCLConsensus::Adaptor and test CSF Peer
This is the foundational data structure work for the RNG implementation.
The gating logic and entropy computation will follow.
Fixes the use of high and low in variable names, as these are determined by ripple::keylet::line processing.

std::endl triggers flush() which calls sync() on the shared log buffer.
Multiple threads racing in sync() cause str()/str("") operations to
corrupt buffer state, leading to crashes and double frees.
Added mutex to serialize access to suite.log, preventing concurrent
sync() calls on the same buffer.
* Match unit tests on start of test name (#4634)
* For example, without this change, to run the TxQ tests, must specify
`--unittest=TxQ1,TxQ2` on the command line. With this change, can use
`--unittest=TxQ`, and both will be run.
* An exact match will prevent any further partial matching.
* This could have some side effects for different tests with a common
name beginning. For example, NFToken, NFTokenBurn, NFTokenDir. This
might be useful. If not, the shorter-named test(s) can be renamed. For
example, NFToken to NFTokens.
* Split the NFToken, NFTokenBurn, and Offer test classes. Potentially speeds
up parallel tests by a factor of 5.
* SetHook_test, SetHookTSH_test, XahauGenesis_test
