ff763a500c feat: log transform for test output (r-address → Account(name), prefix)
- Log.h: add setTransform/applyTransform on Logs for message rewriting
- SuiteJournal.h: wire transform into SuiteJournalSink so test output
  goes through it (previously bypassed Logs::write entirely)
- Env.h: pass Logs* to SuiteJournalSink
- TestEnv.h: add setPrefix() for per-phase log labels, prepend prefix
  in transform

usage:
  auto env = makeEnv(features);
  auto const& alice = env.account("alice");
  env.setPrefix("deposit phase");
  // logs: TRC:HooksTrace [deposit phase] HookTrace[Account(alice)-...]: ...

  TESTENV_LOGGING="HooksTrace=trace,View=debug"

bfcbbc3c5e feat: migrate coverage from sancov to hookz __on_source_line
replace sancov-based coverage instrumentation with hookz's DWARF-based
__on_source_line(line, col) approach. line/col arrive as direct arguments
so no post-processing symbolication step is needed.

- Guard.h: allow result_count == 0 for void-returning whitelisted imports
- Enum.h: replace sancov whitelist entries with __on_source_line
- applyHook.h: replace sancov callbacks with onSourceLine, emit line:col
- SetHook.cpp: re-enable guard validation (was disabled for sancov testing)
- CMake: use hookz build-test-hooks, add HOOKS_FORCE_RECOMPILE support
- remove obsolete HookCoverage sancov test files

- account("name"): auto-registers r-address → Account(name) in logs

  per-partition log levels without code changes

b7aeff95a9 feat: add log transform to Logs for test-time message rewriting
Logs::setTransform(fn) installs a function that transforms every log
message before output. Useful in tests to replace raw r-addresses
with human-readable account names.

Usage:
  env.app().logs().setTransform([&](std::string const& text) {
      std::string out = text;
      // replace rG1QQv2... with Account(alice)
      boost::algorithm::replace_all(out, toBase58(alice.id()), "Account(alice)");
      return out;
  });
  // Pass nullptr to clear:
  env.app().logs().setTransform(nullptr);

65166a9329 feat: route hook trace output to dedicated HooksApi journal
- Macro.h: add `jh` journal for HooksApi partition in HOOK_SETUP()
- applyHook.cpp: trace, trace_num, trace_float now use jh + JLOG macro
  for line numbers and separate partition filtering
- SuiteLogsWithOverrides.h: per-partition severity overrides for tests

Usage in tests:
  Env env{*this, envconfig(), features,
      std::make_unique<SuiteLogsWithOverrides>(*this,
          SuiteLogsWithOverrides::Overrides{{"HooksApi", Sev::kTrace}})};

- RippledCore.cmake: HOOKS_TEST_DIR, HOOKS_C_DIR, HOOKS_COVERAGE,

8673599d2b fixAMMClawbackRounding: adjust last holder's LPToken balance (#5513)
Due to rounding, the LPTokenBalance of the last LP might not match the LP's trustline balance. This was fixed for `AMMWithdraw` in `fixAMMv1_1` by adjusting the LPTokenBalance to be the same as the trustline balance. Since `AMMClawback` is also performing a withdrawal, we need to adjust LPTokenBalance as well in `AMMClawback.`

This change includes:
1. Refactored `verifyAndAdjustLPTokenBalance` function in `AMMUtils`, which both`AMMWithdraw` and `AMMClawback` call to adjust LPTokenBalance.
2. Added the unit test `testLastHolderLPTokenBalance` to test the scenario.
3. Modify the existing unit tests for `fixAMMClawbackRounding`.

65837f49e1 fix: Add AMMv1_3 amendment (#5203)
* Add AMM bid/create/deposit/swap/withdraw/vote invariants:
  - Deposit, Withdrawal invariants: `sqrt(asset1Balance * asset2Balance) >= LPTokens`.
  - Bid: `sqrt(asset1Balance * asset2Balance) > LPTokens` and the pool balances don't change.
  - Create: `sqrt(asset1Balance * assetBalance2) == LPTokens`.
  - Swap: `asset1BalanceAfter * asset2BalanceAfter >= asset1BalanceBefore * asset2BalanceBefore`
     and `LPTokens` don't change.
  - Vote: `LPTokens` and pool balances don't change.
  - All AMM and swap transactions: amounts and tokens are greater than zero, except on withdrawal if all tokens
    are withdrawn.
* Add AMM deposit and withdraw rounding to ensure AMM invariant:
  - On deposit, tokens out are rounded downward and deposit amount is rounded upward.
  - On withdrawal, tokens in are rounded upward and withdrawal amount is rounded downward.
* Add Order Book Offer invariant to verify consumed amounts. Consumed amounts are less than the offer.
* Fix Bid validation. `AuthAccount` can't have duplicate accounts or the submitter account.

"""
json-tx: field-aware packer for (tx_json_str, signature).
The ripple binary codec already decomposes a transaction into ordered
(field_name, canonical_bytes) pairs. We reuse that as the dictionary.
Opcode stream:
OP_FIELD i -> render field i exactly as it appears in tx_json_str
OP_TAG t -> emit a glue snippet from TAGS (',', ':', '"', ...)
OP_RAW n <bytes> -> n bytes of literal passthrough
OP_END -> terminator
The stream is what gets stored in the `JsonTxCompressed` Blob field on
the wire. The TxnSignature field still carries the ed25519/secp256k1
signature, but that signature is now over the ASCII `tx_json_str`, not
the classical signing payload.

// 1. Parse tx_json_str as JSON.
// 2. Verify `signature` over the UTF-8 bytes of tx_json_str using
// SigningPubKey from the parsed object -- NOT the classical

// 3. Build an STTx from the parsed object + signature.

// 5. Route through the normal Transaction / processTransaction flow.
//
// NB: for this to survive peer relay / re-validation a consensus-level
// change is required: a new `sfJsonTxBody` Blob field that carries
// tx_json_str on chain, plus an amendment that routes STTx::checkSign
// through the ASCII bytes when the field is present. This handler is
