-# Workflow Orchestration
-
-## 1. Plan Mode Default
-- Enter plan mode for ANY non-trivial task (3+ steps or architectural decisions)
-- If something goes sideways, STOP and re-plan immediately - don't keep pushing
-- Use plan mode for verification steps, not just building
-- Write detailed specs upfront to reduce ambiguity
-
-## 2. Subagent Strategy
-- Use subagents liberally to keep main context window clean
-- Offload research, exploration, and parallel analysis to subagents
-- For complex problems, throw compute at it via parallelizing
-- One task per subagent for focused execution
-
-## 3. Self-Improvement Loop
-- After ANY correction from the user: update `tasks/lessons.md` with the pattern
-- Write rules for yourself that prevent the same mistake
-- Ruthlessly iterate on these rules until mistake drops
-- Review lessons at session start for relevant project
-
-## 4. Verification Before Done
-- Never mark a task complete without proving it works
-- Diff behavior between main and your changes when relevant
-- Ask yourself: "Would a staff engineer approve this?"
-- Run tests, check logs, demonstrate correctness
-
-## 5. Demand Elegance (Balanced)
-- For non-trivial changes: pause and ask "is there a more elegant way?"
-- If a fix feels hacky: "Know now, do later, implement the elegant solution"
-- Skip this for simple, obvious fixes - don't over-engineer
-- Challenge your own first solution
-
-## 6. Autonomous Bug Fixing
-- When given a bug report: just fix it. Don't ask for hand-holding
-- Point at logs, errors, failing tests - then resolve them
-- Zero context switching required from the user
-- Go fix failing CI tests without being told how
-
-# Task Management
-
-1. **Plan First**: Write plan to `tasks/todo.md` with checkable items
-2. **Verify Plans**: Check in before starting implementation
-3. **Track Progress**: Mark items complete as you go
-4. **Explain Changes**: High-level summary at each step
-5. **Document Results**: Add review section to `tasks/todo.md`
-6. **Capture Lessons**: Update `tasks/lessons.md` after corrections
-
-# Core Principles
-
-**Simplicity First**: Make every change as simple as possible. Impact minimal code.
-
-**No Boilerplate**: Skip documentation. No README/docs bloat. Test only if requested.
-
-**Minimal Impact**: Changes should only touch what's necessary. Avoid introducing bugs.

-# XRPL Amendment Creation Skill
-
-This skill guides you through creating XRPL amendments, whether for brand new features or fixes/extensions to existing functionality.
-
-## Amendment Types
-
-There are two main types of amendments:
-
-1. **New Feature Amendment** (`feature{Name}`) - Entirely new functionality
-2. **Fix/Extension Amendment** (`fix{Name}`) - Modifications to existing functionality
-
-## Step 1: Determine Amendment Type
-
-Ask the user:
-- Is this a **brand new feature** (new transaction type, ledger entry, or capability)?
-- Or is this a **fix or extension** to existing functionality?
-
----
-
-## For NEW FEATURE Amendments
-
-### Checklist:
-
-#### 1. Feature Definition in features.macro
-**ONLY FILE TO EDIT:** `include/xrpl/protocol/detail/features.macro`
-
-- [ ] Add to TOP of features.macro (reverse chronological order):
-```
-XRPL_FEATURE(YourFeatureName, Supported::no, VoteBehavior::DefaultNo)
-```
-- [ ] This creates the variable `featureYourFeatureName` automatically
-- [ ] Follow naming convention: Use the feature name WITHOUT the "feature" prefix
-- [ ] Examples: `Batch` → `featureBatch`, `LendingProtocol` → `featureLendingProtocol`
-
-#### 2. Support Status
-- [ ] Start with `Supported::no` during development
-- [ ] Change to `Supported::yes` when ready for network voting
-- [ ] Use `VoteBehavior::DefaultNo` (validators must explicitly vote for it)
-
-#### 3. Code Implementation
-- [ ] Implement new functionality (transaction type, ledger entry, etc.)
-- [ ] Add feature gate check in preflight:
-```cpp
-if (!env.current()->rules().enabled(feature{Name}))
-{
-    return temDISABLED;
-}
-```
-
-#### 4. Disable Route Handling
-- [ ] Ensure transaction returns `temDISABLED` when amendment is disabled
-- [ ] Implement early rejection in preflight/preclaim phase
-- [ ] Add appropriate error messages
-
-#### 5. Test Implementation
-Create comprehensive test suite with this structure:
-
-```cpp
-class {FeatureName}_test : public beast::unit_test::suite
-{
-public:
-    void testEnable(FeatureBitset features)
-    {
-        testcase("enabled");
-
-        // Test with feature DISABLED
-        {
-            auto const amendNoFeature = features - feature{Name};
-            Env env{*this, amendNoFeature};
-
-            env(transaction, ter(temDISABLED));
-        }
-
-        // Test with feature ENABLED
-        {
-            Env env{*this, features};
-
-            env(transaction, ter(tesSUCCESS));
-            // Validate new functionality works
-        }
-    }
-
-    void testPreflight(FeatureBitset features)
-    {
-        testcase("preflight");
-        // Test malformed transaction validation
-    }
-
-    void testPreclaim(FeatureBitset features)
-    {
-        testcase("preclaim");
-        // Test signature and claim phase validation
-    }
-
-    void testWithFeats(FeatureBitset features)
-    {
-        testEnable(features);
-        testPreflight(features);
-        testPreclaim(features);
-        // Add feature-specific tests
-    }
-
-    void run() override
-    {
-        using namespace test::jtx;
-        auto const all = supported_amendments();
-        testWithFeats(all);
-    }
-};
-```
-
-#### 6. Test Coverage Requirements
-- [ ] Test amendment DISABLED state (returns `temDISABLED`)
-- [ ] Test amendment ENABLED state (returns `tesSUCCESS`)
-- [ ] Test malformed transactions
-- [ ] Test signature validation
-- [ ] Test edge cases specific to feature
-- [ ] Test amendment transition behavior
-
-#### 7. Documentation
-- [ ] Create specification document (XLS_{NAME}.md)
-- [ ] Document new transaction types, ledger entries, or capabilities
-- [ ] Create test plan document
-- [ ] Document expected behavior when enabled/disabled
-
----
-
-## For FIX/EXTENSION Amendments
-
-### Checklist:
-
-#### 1. Fix Definition in features.macro
-**ONLY FILE TO EDIT:** `include/xrpl/protocol/detail/features.macro`
-
-- [ ] Add to TOP of features.macro (reverse chronological order):
-```
-XRPL_FIX(YourFixName, Supported::no, VoteBehavior::DefaultNo)
-```
-- [ ] This creates the variable `fixYourFixName` automatically
-- [ ] Follow naming convention: Use the fix name WITHOUT the "fix" prefix (it's added automatically)
-- [ ] Examples: `TokenEscrowV1` → `fixTokenEscrowV1`, `DirectoryLimit` → `fixDirectoryLimit`
-- [ ] Start with `Supported::no` during development, change to `Supported::yes` when ready
-
-#### 2. Backward Compatibility Implementation
-**Critical**: Use enable() with if/else to preserve existing functionality
-
-```cpp
-// Check if fix is enabled
-bool const fix{Name} = env.current()->rules().enabled(fix{Name});
-
-// Conditional logic based on amendment state
-if (fix{Name})
-{
-    // NEW behavior with fix applied
-    // This is the corrected/improved logic
-}
-else
-{
-    // OLD behavior (legacy path)
-    // Preserve original functionality for backward compatibility
-}
-```
-
-**Alternative pattern with ternary operator:**
-```cpp
-auto& viewToUse = sb.rules().enabled(fix{Name}) ? sb : legacyView;
-```
-
-#### 3. Multiple Fix Versions Pattern
-For iterative fixes, use version checking:
-
-```cpp
-bool const fixV1 = rv.rules().enabled(fixXahauV1);
-bool const fixV2 = rv.rules().enabled(fixXahauV2);
-
-switch (transactionType)
-{
-    case TYPE_1:
-        if (fixV1) {
-            // Behavior with V1 fix
-        } else {
-            // Legacy behavior
-        }
-        break;
-
-    case TYPE_2:
-        if (fixV2) {
-            // Behavior with V2 fix
-        } else if (fixV1) {
-            // Behavior with only V1
-        } else {
-            // Legacy behavior
-        }
-        break;
-}
-```
-
-#### 4. Test Both Paths
-Always test BOTH enabled and disabled states:
-
-```cpp
-void testFix(FeatureBitset features)
-{
-    testcase("fix behavior");
-
-    for (bool withFix : {false, true})
-    {
-        auto const amend = withFix ? features : features - fix{Name};
-        Env env{*this, amend};
-
-        // Setup test scenario
-        env.fund(XRP(1000), alice);
-        env.close();
-
-        if (!withFix)
-        {
-            // Test OLD behavior (before fix)
-            env(operation, ter(expectedErrorWithoutFix));
-            // Verify old behavior is preserved
-        }
-        else
-        {
-            // Test NEW behavior (after fix)
-            env(operation, ter(expectedErrorWithFix));
-            // Verify fix works correctly
-        }
-    }
-}
-```
-
-#### 5. Security Fix Pattern
-For security-critical fixes (like fixBatchInnerSigs):
-
-```cpp
-// Test vulnerability exists WITHOUT fix
-{
-    auto const amendNoFix = features - fix{Name};
-    Env env{*this, amendNoFix};
-
-    // Demonstrate vulnerability
-    // Expected: Validity::Valid (WRONG - vulnerable!)
-    BEAST_EXPECT(result == Validity::Valid);
-}
-
-// Test vulnerability is FIXED WITH amendment
-{
-    Env env{*this, features};
-
-    // Demonstrate fix
-    // Expected: Validity::SigBad (CORRECT - protected!)
-    BEAST_EXPECT(result == Validity::SigBad);
-}
-```
-
-#### 6. Test Coverage Requirements
-- [ ] Test fix DISABLED (legacy behavior preserved)
-- [ ] Test fix ENABLED (new behavior applied)
-- [ ] Test amendment transition
-- [ ] For security fixes: demonstrate vulnerability without fix
-- [ ] For security fixes: demonstrate protection with fix
-- [ ] Test edge cases that triggered the fix
-- [ ] Test combinations with other amendments
-
-#### 7. Documentation
-- [ ] Document what was broken/suboptimal
-- [ ] Document the fix applied
-- [ ] Document backward compatibility behavior
-- [ ] Create test summary showing both paths
-
----
-
-## Best Practices for All Amendments
-
-### 1. Naming Conventions
-- New features: `feature{DescriptiveName}` (e.g., `featureBatch`, `featureHooks`)
-- Fixes: `fix{IssueDescription}` (e.g., `fixBatchInnerSigs`, `fixNSDelete`)
-- Use CamelCase without underscores
-
-### 2. Feature Flag Checking
-```cpp
-// At the point where behavior diverges:
-bool const amendmentEnabled = env.current()->rules().enabled(feature{Name});
-
-// Or in view/rules context:
-if (!rv.rules().enabled(feature{Name}))
-    return {};  // or legacy behavior
-```
-
-### 3. Error Codes
-- New features when disabled: `temDISABLED`
-- Fixes may return different validation errors based on state
-- Document all error code changes
-
-### 4. Test Structure Template
-```cpp
-class Amendment_test : public beast::unit_test::suite
-{
-public:
-    // Core tests
-    void testEnable(FeatureBitset features);      // Enable/disable states
-    void testPreflight(FeatureBitset features);   // Validation
-    void testPreclaim(FeatureBitset features);    // Claim phase
-
-    // Feature-specific tests
-    void test{SpecificScenario1}(FeatureBitset features);
-    void test{SpecificScenario2}(FeatureBitset features);
-
-    // Master orchestrator
-    void testWithFeats(FeatureBitset features)
-    {
-        testEnable(features);
-        testPreflight(features);
-        testPreclaim(features);
-        test{SpecificScenario1}(features);
-        test{SpecificScenario2}(features);
-    }
-
-    void run() override
-    {
-        using namespace test::jtx;
-        auto const all = supported_amendments();
-        testWithFeats(all);
-    }
-};
-
-BEAST_DEFINE_TESTSUITE(Amendment, app, ripple);
-```
-
-### 5. Documentation Files
-Create these files:
-- **Specification**: `XLS_{FEATURE_NAME}.md` - Technical specification
-- **Test Plan**: `{FEATURE}_COMPREHENSIVE_TEST_PLAN.md` - Test strategy
-- **Test Summary**: `{FEATURE}_TEST_IMPLEMENTATION_SUMMARY.md` - Test results
-- **Review Findings**: `{FEATURE}_REVIEW_FINDINGS.md` (if applicable)
-
-### 6. Amendment Transition Testing
-Test the moment an amendment activates:
-
-```cpp
-void testAmendmentTransition(FeatureBitset features)
-{
-    testcase("amendment transition");
-
-    // Start with amendment disabled
-    auto const amendNoFeature = features - feature{Name};
-    Env env{*this, amendNoFeature};
-
-    // Perform operations in disabled state
-    env(operation1, ter(temDISABLED));
-
-    // Enable amendment mid-test (if testing mechanism supports it)
-    // Verify state transitions correctly
-
-    // Perform operations in enabled state
-    env(operation2, ter(tesSUCCESS));
-}
-```
-
-### 7. Cache Behavior
-If amendment affects caching (like fixBatchInnerSigs):
-- [ ] Test cache behavior without fix
-- [ ] Test cache behavior with fix
-- [ ] Document cache invalidation requirements
-
-### 8. Multi-Amendment Combinations
-Test interactions with other amendments:
-
-```cpp
-void testMultipleAmendments(FeatureBitset features)
-{
-    // Test all combinations
-    for (bool withFeature1 : {false, true})
-    for (bool withFeature2 : {false, true})
-    {
-        auto amend = features;
-        if (!withFeature1) amend -= feature1;
-        if (!withFeature2) amend -= feature2;
-
-        Env env{*this, amend};
-        // Test interaction behavior
-    }
-}
-```
-
-### 9. Performance Considerations
-- [ ] Minimize runtime checks (cache `rules().enabled()` result if used multiple times)
-- [ ] Avoid nested feature checks where possible
-- [ ] Document performance impact
-
-### 10. Code Review Checklist
-- [ ] Both enabled/disabled paths are tested
-- [ ] Backward compatibility is preserved (for fixes)
-- [ ] Error codes are appropriate
-- [ ] Documentation is complete
-- [ ] Security implications are considered
-- [ ] Cache behavior is correct
-- [ ] Edge cases are covered
-

-
-## Common Patterns Reference
-
-### Pattern: New Transaction Type
-```cpp
-// In transactor code:
-TER doApply() override
-{
-    if (!ctx_.view().rules().enabled(feature{Name}))
-        return temDISABLED;
-
-    // New transaction logic here
-    return tesSUCCESS;
-}
-```
-
-### Pattern: New Ledger Entry Type
-```cpp
-// In ledger entry creation:
-if (!view.rules().enabled(feature{Name}))
-    return temDISABLED;
-
-auto const sle = std::make_shared<SLE>(ltNEW_TYPE, keylet);
-view.insert(sle);
-```
-
-### Pattern: Behavioral Fix
-```cpp
-// At decision point:
-bool const useFix = view.rules().enabled(fix{Name});
-
-if (useFix)
-{
-    // Corrected behavior
-    return performCorrectValidation();
-}
-else
-{
-    // Legacy behavior (preserved for compatibility)
-    return performLegacyValidation();
-}
-```
-
-### Pattern: View Selection
-```cpp
-// Select which view to use based on amendment:
-auto& applyView = sb.rules().enabled(feature{Name}) ? newView : legacyView;
-```
-
----
-
-## Example Workflows
-
-### Workflow 1: Creating a New Feature Amendment
-
-1. User requests: "Add a new ClaimReward transaction type"
-2. Skill asks: "What should the amendment be called? (e.g., BalanceRewards - without 'feature' prefix)"
-3. Add to features.macro:
-```
-XRPL_FEATURE(BalanceRewards, Supported::no, VoteBehavior::DefaultNo)
-```
-4. Implement transaction with `temDISABLED` gate using `featureBalanceRewards`
-5. Create test suite with testEnable, testPreflight, testPreclaim
-6. Run tests with amendment enabled and disabled
-7. When ready, update to `Supported::yes` in features.macro
-8. Create specification document
-9. Review checklist
-
-### Workflow 2: Creating a Fix Amendment
-
-1. User requests: "Fix the signature validation bug in batch transactions"
-2. Skill asks: "What should the fix be called? (e.g., BatchInnerSigs - without 'fix' prefix)"
-3. Add to features.macro:
-```
-XRPL_FIX(BatchInnerSigs, Supported::no, VoteBehavior::DefaultNo)
-```
-4. Implement fix with if/else using `fixBatchInnerSigs` to preserve old behavior
-5. Create test demonstrating vulnerability without fix
-6. Create test showing fix works when enabled
-7. When ready, update to `Supported::yes` in features.macro
-8. Document both code paths
-9. Review checklist
-
----
-
-## Quick Reference: File Locations
-
-- **Amendment definitions (ONLY place to add)**: `include/xrpl/protocol/detail/features.macro`
-- **Feature.h (auto-generated, DO NOT EDIT)**: `include/xrpl/protocol/Feature.h`
-- **Feature.cpp (auto-generated, DO NOT EDIT)**: `src/libxrpl/protocol/Feature.cpp`
-- **Test files**: `src/test/app/` or `src/test/protocol/`
-- **Specifications**: Project root (e.g., `XLS_SMART_CONTRACTS.md`)
-- **Test plans**: Project root (e.g., `BATCH_COMPREHENSIVE_TEST_PLAN.md`)
-
-## How the Macro System Works
-
-The amendment system uses C preprocessor macros:
-
-1. **features.macro** - Single source of truth (ONLY file you edit):
-```
-XRPL_FEATURE(Batch, Supported::yes, VoteBehavior::DefaultNo)
-XRPL_FIX(TokenEscrowV1, Supported::yes, VoteBehavior::DefaultNo)
-```
-
-2. **Feature.h** - Auto-generated declarations from macro:
-```cpp
-extern uint256 const featureBatch;
-extern uint256 const fixTokenEscrowV1;
-```
-
-3. **Feature.cpp** - Auto-generated registrations from macro:
-```cpp
-uint256 const featureBatch = registerFeature("Batch", ...);
-uint256 const fixTokenEscrowV1 = registerFeature("fixTokenEscrowV1", ...);
-```
-
-**DO NOT** modify Feature.h or Feature.cpp directly - they process features.macro automatically.

-# xrpld Codebase Skills Index
-
-## Description
-This is the top-level guide for all best-practices skills in this repository. Use this to understand the codebase organization and find the right skill for any task.
-
-## When to Use Skills
-Reference a skill whenever you are:
-- **Writing new code** in a module - check the skill first for established patterns
-- **Modifying existing code** - verify your changes follow module conventions
-- **Adding a new transaction type** - see `libxrpl/tx/transactors.md` for the full template
-- **Debugging** - skills list key files and common pitfalls per module
-- **Reviewing code** - skills document what "correct" looks like for each module
-
-## Codebase Architecture
-
-The codebase is split into two main areas:
-
-### `src/libxrpl/` — The Library (skills in `.claude/skills/libxrpl/`)
-Reusable library code: data types, serialization, cryptography, ledger state, transaction processing, and storage. This is the **protocol layer**.
-
-| Module | Responsibility |
-|--------|---------------|
-| `basics` | Foundational types: Buffer, Slice, base_uint, Number, logging, error contracts |
-| `beast` | Support layer: Journal logging, test framework, instrumentation, IP types |
-| `conditions` | Crypto-conditions (RFC): fulfillment validation, DER encoding |
-| `core` | Job queue, load monitoring, hash-based message dedup |
-| `crypto` | CSPRNG, secure erasure, RFC1751 encoding |
-| `json` | Json::Value, parsing, serialization, StaticString optimization |
-| `ledger` | ReadView/ApplyView, state tables, payment sandbox, credit ops |
-| `net` | HTTP/HTTPS client, SSL certs, async I/O |
-| `nodestore` | Persistent node storage: RocksDB, NuDB, Memory backends |
-| `protocol` | STObject hierarchy, SField, Serializer, TER codes, Features, Keylets |
-| `proto` | Protocol Buffer generated headers (gRPC API definitions) |
-| `rdb` | SOCI database wrapper, checkpointing |
-| `resource` | Rate limiting, endpoint tracking, abuse prevention |
-| `server` | Port config, SSL/TLS, WebSocket, admin networks |
-| `shamap` | SHA-256 Merkle radix tree (16-way branching, COW) |
-| `tx` | Transaction pipeline: Transactor base, preflight/preclaim/doApply |
-
-### `src/xrpld/` — The Server Application (skills in `.claude/skills/xrpld/`)
-The running rippled server: application lifecycle, consensus, networking, RPC, and peer management. This is the **application layer**.
-
-| Module | Responsibility |
-|--------|---------------|
-| `app` | Application singleton, ledger management, consensus adapters, services |
-| `app/main` | Application initialization and lifecycle |
-| `app/ledger` | Ledger storage, retrieval, immutable state management |
-| `app/consensus` | RCL consensus adapters (bridges generic algorithm to rippled) |
-| `app/misc` | Fee voting, amendments, SHAMapStore, TxQ, validators, NetworkOPs |
-| `app/paths` | Payment path finding algorithm, trust line caching |
-| `app/rdb` | Application-level database operations |
-| `app/tx` | Application-level transaction handling |
-| `consensus` | Generic consensus algorithm (CRTP-based, app-independent) |
-| `core` | Configuration (Config.h), time keeping, network ID |
-| `overlay` | P2P networking: peer connections, protocol buffers, clustering |
-| `peerfinder` | Network discovery: bootcache, livecache, slot management |
-| `perflog` | Performance logging and instrumentation |
-| `rpc` | RPC handler dispatch, coroutine suspension, 40+ command handlers |
-| `shamap` | Application-level SHAMap operations (NodeFamily) |
-
-### `include/xrpl/` — Header Files
-Headers live in `include/xrpl/` and mirror the `src/libxrpl/` structure. Each skill already references its corresponding headers in the "Key Files" section.
-
-## Cross-Cutting Conventions
-
-### Error Handling
-- **Transaction errors**: Return `TER` enum (tesSUCCESS, tecFROZEN, temBAD_AMOUNT, etc.)
-- **Logic errors**: `Throw<std::runtime_error>()`, `LogicError()`, `XRPL_ASSERT()`
-- **I/O errors**: `Status` enum or `boost::system::error_code`
-- **RPC errors**: Inject via `context.params`
-
-### Assertions
-```cpp
-XRPL_ASSERT(condition, "ClassName::method : description");  // Debug only
-XRPL_VERIFY(condition, "ClassName::method : description");  // Always enabled
-```
-
-### Logging
-```cpp
-JLOG(j_.warn()) << "Message";  // Always wrap in JLOG macro
-```
-
-### Memory Management
-- `IntrusiveRefCounts` + `SharedIntrusive` for shared ownership in libxrpl
-- `std::shared_ptr` for shared ownership in xrpld
-- `std::unique_ptr` for exclusive ownership
-- `CountedObject<T>` mixin for instance tracking
-
-### Feature Gating
-```cpp
-if (ctx.rules.enabled(featureMyFeature)) { /* new behavior */ }
-```
-
-### Code Organization
-- Headers in `include/xrpl/`, implementations in `src/libxrpl/` or `src/xrpld/`
-- `#pragma once` (never `#ifndef` guards)
-- `namespace xrpl { }` for all code
-- `detail/` namespace for internal helpers
-- Factory functions: `make_*()` returning `unique_ptr` or `shared_ptr`

-# Basics Module Best Practices
-
-## Description
-Use when working with foundational utilities in `src/libxrpl/basics/` or `include/xrpl/basics/`. Covers data structures, memory management, logging, numeric operations, error handling, and string utilities.
-
-## Responsibility
-Provides fundamental building blocks for the entire codebase: memory types (Buffer, Slice, Blob), intrusive smart pointers, arbitrary-precision integers (base_uint), multi-precision decimal arithmetic (Number), logging infrastructure, exception handling contracts, and platform abstractions.
-
-## Key Patterns
-
-### Memory Types
-- **Slice** - Non-owning view into contiguous bytes (like std::span)
-- **Buffer** - Owning byte container (like std::vector<uint8_t>)
-- **Blob** - Alias for std::vector<unsigned char>
-- Prefer `Slice` for read-only parameters, `Buffer` for owned data
-
-### Intrusive Smart Pointers
-```cpp
-// Prefer intrusive pointers over std::shared_ptr for minimal overhead
-// Object embeds its own reference count
-class MyObject : public IntrusiveRefCounts {
-    // ...
-};
-// Use SharedIntrusive<MyObject> when weak pointers needed
-```
-
-### Error Handling
-```cpp
-// Contract-based exceptions (logs call stack then throws)
-Throw<std::runtime_error>("Invalid source file");
-LogThrow("exception message");
-
-// Logic errors for invariant violations
-LogicError("This should never happen");
-
-// Assertions (fuzzing-aware)
-XRPL_ASSERT(condition, "function_name : description");
-XRPL_VERIFY(condition, "message");  // Always enabled, not just debug
-```
-
-### Logging
-```cpp
-// Use JLOG macro - short-circuits if level disabled
-JLOG(debugLog().warn()) << "Message: " << value;
-JLOG(j_.trace()) << "Verbose detail";
-// Never: debugLog().warn() << "msg";  // Missing JLOG wastes formatting
-```
-
-### Number Precision
-```cpp
-// Use Number for multi-precision decimal arithmetic
-// Always use RAII guard for rounding mode
-NumberRoundModeGuard mg(Number::towards_zero);
-auto result = amount * rate;
-// Guard restores previous mode on scope exit
-```
-
-### base_uint Template
-```cpp
-// Typed big-endian integers: base_uint<Bits, Tag>
-// Tag prevents mixing unrelated types of same width
-using uint256 = base_uint<256, void>;
-using AccountID = base_uint<160, detail::AccountIDTag>;
-```
-
-## Common Pitfalls
-- Never use `std::shared_ptr` when IntrusiveRefCounts is available - it adds a separate allocation
-- Never format log messages without JLOG wrapper - wastes CPU when level is disabled
-- Never use raw `assert()` - use `XRPL_ASSERT` for fuzzing instrumentation support
-- Never mix `Buffer` and `Slice` ownership semantics - Slice does NOT own its data

-# Beast Module Best Practices
-
-## Description
-Use when working with the Beast support layer in `src/libxrpl/beast/` or `include/xrpl/beast/`. Covers networking types, unit testing, Journal logging, and instrumentation.
-
-## Responsibility
-Library support layer providing network types (IP addresses, endpoints), unit testing framework, Journal/logging abstractions, instrumentation/assertion macros, and type introspection utilities.
-
-## Key Patterns
-
-### Journal Logging
-```cpp
-// Journal wraps a Sink pointer - copy by value is cheap
-beast::Journal const j_;
-
-// Severity levels: kTrace, kDebug, kInfo, kWarning, kError, kFatal
-JLOG(j_.warn()) << "User-facing issue";
-JLOG(j_.debug()) << "Implementation detail";
-JLOG(j_.trace()) << "Very verbose diagnostic";
-JLOG(j_.error()) << "Unexpected failure";
-```
-
-### Unit Testing
-```cpp
-class MyTest : public beast::unit_test::suite {
-    void run() override {
-        testcase("feature description");
-        BEAST_EXPECT(value == expected);    // Non-fatal assertion
-        BEAST_REQUIRE(value == expected);   // Fatal - aborts test on failure
-    }
-};
-BEAST_DEFINE_TESTSUITE(MyTest, module, ripple);
-```
-
-### Instrumentation
-```cpp
-// Use XRPL_ASSERT for debug-only assertions (fuzzing-aware)
-XRPL_ASSERT(ptr != nullptr, "MyClass::method : null pointer");
-
-// Format: "ClassName::methodName : description"
-// The string format is important for fuzzing instrumentation
-```
-
-### IP Endpoint Types
-```cpp
-// Use beast::IP::Endpoint for network addresses
-beast::IP::Endpoint endpoint;
-// Supports both IPv4 and IPv6
-// Includes port information
-```
-
-## Common Pitfalls
-- Never use `BEAST_EXPECT` when the test cannot continue on failure - use `BEAST_REQUIRE` instead
-- Never create a Journal with a dangling Sink pointer - ensure Sink outlives Journal
-- Always include "ClassName::methodName" prefix in XRPL_ASSERT messages for traceability

-# Beast Clock Module Best Practices
-
-## Description
-Use when working with clock abstractions in `src/libxrpl/beast/clock/` or `include/xrpl/beast/clock/`. Covers abstract clock interfaces and manual clock implementations for testing.
-
-## Responsibility
-Provides clock abstractions that decouple code from system time, enabling deterministic testing with manual clocks and supporting different time granularities.
-
-## Key Patterns
-
-### Abstract Clock Interface
-```cpp
-// Use abstract_clock<T> for testable time-dependent code
-// Production: uses system clock
-// Testing: uses manual_clock for deterministic control
-```
-
-### Manual Clock for Testing
-```cpp
-// Advance time manually in tests
-manual_clock<std::chrono::steady_clock> clock;
-clock.advance(std::chrono::seconds(30));
-// Deterministic - no flaky tests from timing issues
-```
-
-## Common Pitfalls
-- Never use `std::chrono::system_clock::now()` directly - inject clock dependency
-- Always use manual_clock in unit tests for deterministic behavior
-- Be aware of Ripple Epoch vs Unix Epoch when working with ledger timestamps

-## Description
-Use when working with metrics and monitoring in `src/libxrpl/beast/insight/` or `include/xrpl/beast/insight/`. Covers counters, gauges, and metrics collection.
-
-## Responsibility
-Provides metrics collection infrastructure for monitoring application performance: counters for cumulative values, gauges for point-in-time measurements, and hooks for metrics export.
-
-## Key Patterns
-
-### Metrics Types
-```cpp
-// Counter: Monotonically increasing value (e.g., total requests)
-insight::Counter requests;
-++requests;
-
-// Gauge: Point-in-time value (e.g., current connections)
-insight::Gauge connections;

-```
-
-### Null Metrics
-```cpp
-// Use NullCollector when metrics disabled
-// All operations become no-ops with zero overhead
-auto collector = insight::NullCollector::New();
-```
-
-## Common Pitfalls
-- Use Counter for cumulative values, Gauge for current state - don't mix them

-
-## Responsibility
-Provides network type abstractions for IP addresses (v4 and v6) and endpoints (address + port), with parsing utilities and comparison operators.
-
-## Key Patterns
-
-### IP Endpoint Usage
-```cpp
-// beast::IP::Endpoint combines address + port
-beast::IP::Endpoint endpoint(
-    beast::IP::Address::from_string("127.0.0.1"), 51235);
-
-// Supports both IPv4 and IPv6
-beast::IP::Endpoint v6endpoint(
-    beast::IP::Address::from_string("::1"), 51235);
-```
-
-### Address Parsing
-```cpp
-// Parse from string with error handling
-boost::system::error_code ec;
-auto address = beast::IP::Address::from_string(input, ec);
-if (ec) { /* handle invalid address */ }
-```
-
-### Comparison and Ordering
-```cpp
-// Endpoints support full comparison for use in containers
-std::set<beast::IP::Endpoint> endpoints;
-std::map<beast::IP::Endpoint, Consumer> consumers;
-```

-
-## Responsibility
-Provides utility classes including the Journal logging abstraction (Sink + Stream), XRPL_ASSERT/XRPL_VERIFY instrumentation macros, and type introspection helpers.
-
-## Key Patterns
-
-### Journal and Sink Architecture

-// Sink: abstract base for log message routing
-class Sink {
-    virtual void write(beast::severities::Severity level, std::string const& text) = 0;
-    void console(bool output);  // Enable console output
-};
-
-// Journal: lightweight wrapper around Sink* (copy by value)
-beast::Journal j(sinkPtr);
-JLOG(j.warn()) << "Message";
-
-// WrappedSink: adds prefix to all messages
-beast::WrappedSink wrappedSink(parentSink, "MyModule");
-```
-
-### Instrumentation Macros
-```cpp
-// XRPL_ASSERT: Debug-only assertion (disabled in release, fuzzing-aware)
-XRPL_ASSERT(condition, "ClassName::method : description");
-
-// XRPL_VERIFY: Always-enabled assertion
-XRPL_VERIFY(condition, "ClassName::method : description");
-
-// Format convention: "ClassName::methodName : human-readable description"
-```
-
-## Common Pitfalls
-- Always use "ClassName::methodName" prefix in assertion messages
-- Journal is cheap to copy (just a pointer) - pass by value is fine
-- WrappedSink must outlive any Journal created from it
-- XRPL_ASSERT is no-op in release builds - don't put side effects in the condition

-# Conditions Module Best Practices
-
-## Description
-Use when working with crypto-conditions in `src/libxrpl/conditions/` or `include/xrpl/conditions/`. Implements the RFC crypto-conditions specification.
-
-## Responsibility
-Implements crypto-conditions for conditional payments: condition fingerprints, fulfillment validation, multiple condition types (preimage, prefix, threshold, RSA, Ed25519), and binary DER serialization/deserialization.
-
-## Key Patterns
-
-### Fulfillment Interface
-```cpp
-// Abstract base for all fulfillment types
-struct Fulfillment {
-    virtual ~Fulfillment() = default;
-    virtual Buffer fingerprint() const = 0;
-    virtual Type type() const = 0;
-    virtual bool validate(Slice data) const = 0;
-    virtual std::uint32_t cost() const = 0;
-    virtual Condition condition() const = 0;
-};
-```
-
-### Factory Pattern for Deserialization
-```cpp
-// Returns unique_ptr + sets error_code (non-throwing)
-std::unique_ptr<Fulfillment> deserialize(Slice s, std::error_code& ec);
-
-// Usage:
-std::error_code ec;
-auto fulfillment = Fulfillment::deserialize(data, ec);
-if (ec) return {};  // Early return on error
-```
-
-### Type-Safe Enums
-```cpp
-enum class Type : std::uint8_t {
-    preimageSha256 = 0,
-    prefixSha256 = 1,
-    thresholdSha256 = 2,
-    rsaSha256 = 3,
-    ed25519Sha256 = 4
-};
-```
-
-### Size Limits
-```cpp
-static constexpr std::size_t maxSerializedCondition = 128;
-static constexpr std::size_t maxSerializedFulfillment = 256;
-// Always respect these limits when creating conditions
-```
-
-## Common Pitfalls

-# Core Module Best Practices
-
-## Description
-Use when working with job processing and routing infrastructure in `src/libxrpl/core/` or `include/xrpl/core/`. Covers job queues, load monitoring, and message deduplication.
-
-## Responsibility
-Distributed job processing with priority levels, load monitoring for execution tracking, and hash-based message suppression/routing for peer deduplication.
-
-## Key Patterns
-
-### Job Queue Priorities
-```cpp
-// Job types ordered by priority (lower enum = lower priority)
-enum JobType {
-    jtINVALID = -1,
-    jtPACK,              // Lowest priority
-    jtCLIENT_WEBSOCKET,
-    // ...
-    jtVALIDATION_t,      // Trusted validation (high)
-    jtADMIN              // Admin operations (highest)
-};
-// Position in enum determines scheduling priority
-```
-
-### HashRouter for Deduplication
-```cpp
-// Suppress duplicate messages from peers
-std::optional<std::set<PeerShortID>> shouldRelay(uint256 const& key);
-// Returns {} if already relayed, set of peers if should relay
-
-// Track peer that sent a message
-auto result = router.addSuppressionPeer(key, peer);
-```
-
-### RAII Locking
-```cpp
-// Always use lock_guard for mutex protection
-std::lock_guard lock(mutex_);
-auto result = emplace(key);
-result.first.addPeer(peer);
-return result.second;  // Return while lock is held
-```
-
-### Optional Return Types
-```cpp
-// Use std::optional for "maybe" results
-std::optional<std::set<PeerShortID>> shouldRelay(uint256 const& key);
-// Caller checks: if (auto peers = shouldRelay(key)) { ... }
-```
-
-## Common Pitfalls
-- Never hold locks longer than necessary - lock_guard scope = critical section

-# Crypto Module Best Practices
-
-## Description
-Use when working with cryptographic operations in `src/libxrpl/crypto/` or `include/xrpl/crypto/`. Covers CSPRNG, secure memory erasure, and RFC1751 encoding.
-
-## Responsibility
-Low-level cryptographic operations: cryptographically secure random number generation (CSPRNG), RFC1751 word-based encoding for keys, and secure memory erasure to prevent sensitive data leakage.
-
-## Key Patterns
-
-### CSPRNG Usage
-```cpp
-// Thread-safe PRNG - use the global singleton
-auto& prng = crypto_prng();
-
-// Generate random value
-auto randomValue = prng();
-
-// Fill buffer with random bytes
-prng(buffer.data(), buffer.size());
-
-// NEVER create your own csprng_engine - use crypto_prng()
-```
-
-### Secure Memory Erasure
-```cpp
-// Use volatile memset to prevent compiler optimization
-secure_erase(secretKey.data(), secretKey.size());
-// MUST be called before destroying any buffer containing secrets
-```
-
-### Engine Concept Conformance
-```cpp
-// csprng_engine meets UniformRandomNumberEngine requirements
-using result_type = std::uint64_t;
-static constexpr result_type min();
-static constexpr result_type max();
-// Can be used with standard distributions
-```
-
-## Common Pitfalls
-- Never create a local `csprng_engine` instance - always use `crypto_prng()` singleton
-- Never use `std::rand()` or `std::mt19937` for security-sensitive operations
-- Always call `secure_erase()` on secret key material before destruction
-- Never copy or move a `csprng_engine` - it's non-copyable and non-movable by design
-- Be aware of OpenSSL version differences - locking behavior varies

-## Description
-Use when working with JSON parsing and serialization in `src/libxrpl/json/` or `include/xrpl/json/`. Covers Json::Value, readers, writers, and custom allocators.
-
-## Responsibility
-JSON value representation (discriminated union for all JSON types), parsing text to Value objects, serialization from Value to text, and custom string allocation for memory control.
-
-## Key Patterns
-
-### Json::Value Usage
-```cpp
-// Discriminated union - supports all JSON types
-Json::Value obj(Json::objectValue);
-obj["key"] = "string_value";
-obj["count"] = 42u;
-obj["flag"] = true;
-obj["nested"] = Json::objectValue;
-
-// Array creation
-Json::Value arr(Json::arrayValue);
-arr.append("item");
-arr.append(123);
-
-// Type checking
-if (obj.isObject()) { ... }
-if (obj.isMember("key")) { ... }
-```
-
-### StaticString Optimization
-```cpp
-// Use StaticString for compile-time known keys to avoid allocation
-static const Json::StaticString code("code");
-static const Json::StaticString message("message");
-object[code] = 1234;     // No dynamic allocation for key
-object[message] = "ok";   // Key stored as pointer, not copied
-```
-
-### Value Type Enum
-```cpp
-enum ValueType {
-    nullValue = 0,
-    intValue, uintValue, realValue,
-    stringValue, booleanValue,
-    arrayValue, objectValue
-};
-// Check type before accessing to avoid undefined behavior
-```
-
-### Lazy Initialization
-```cpp
-// Container elements auto-created on access (like JavaScript)
-Json::Value obj;
-obj["newKey"]["nested"] = 1;  // Creates intermediate objects automatically
-// Be aware: accessing a non-existent key creates it
-```
-
-## Common Pitfalls
-- Accessing a non-existent key via `operator[]` creates a null entry - use `isMember()` to check first if you don't want side effects
-- Use `const` overload of `operator[]` to avoid auto-creation: `obj["key"]` on const ref returns null reference
-- Prefer `StaticString` for frequently-used keys to avoid repeated allocations
-- Never assume JSON numeric types - check `isInt()`, `isUInt()`, `isDouble()` explicitly

-# Ledger Module Best Practices
-
-## Description
-Use when working with ledger state management in `src/libxrpl/ledger/` or `include/xrpl/ledger/`. Covers views, state tables, payments, and credit operations.
-
-## Responsibility
-Manages the state of the distributed ledger: abstractions for viewing, reading, and applying transactions to ledger state. Handles account ownership tracking, trust lines, payment processing, directory management, and credential verification.
-
-## Key Patterns
-
-### ReadView vs ApplyView
-```cpp
-// ReadView: Read-only access to ledger state
-bool exists = view.exists(keylet::account(accountID));
-auto sle = view.read(keylet::account(accountID));  // Returns shared_ptr<SLE const>
-
-// ApplyView: Mutable access for transaction application
-auto sle = view.peek(keylet::account(accountID));   // Returns shared_ptr<SLE>
-sle->setFieldAmount(sfBalance, newBalance);
-view.update(sle);   // Commit change
-view.insert(newSle); // Create new entry
-view.erase(sle);     // Remove entry
-```
-
-### Enum-Based Control (No Boolean Blindness)
-```cpp
-// NEVER: bool ignoreFreeze = true;
-// ALWAYS: Use named enums
-enum FreezeHandling { fhIGNORE_FREEZE, fhZERO_IF_FROZEN };
-enum AuthHandling { ahIGNORE_AUTH, ahZERO_IF_UNAUTHORIZED };
-
-STAmount accountHolds(ReadView const& view, AccountID const& account,
-    Currency const& currency, AccountID const& issuer,
-    FreezeHandling zeroIfFrozen, beast::Journal j);
-```
-
-### Asset Variant Handling
-```cpp
-// Use std::visit for Asset (Issue or MPTIssue)
-return std::visit(
-    [&](auto const& issue) {
-        return isIndividualFrozen(view, account, issue);
-    },
-    asset.value());
-```
-
-### PaymentSandbox for Isolation
-```cpp
-// Test payment effects before committing
-PaymentSandbox sandbox(&view);
-// ... apply changes to sandbox ...
-sandbox.apply(view);  // Commit all changes atomically
-// Or let sandbox destruct to discard
-```
-
-### TER Return Codes
-```cpp
-// Transaction results are returned as TER, not exceptions
-TER result = doApply();
-if (result != tesSUCCESS) return result;
-// TER categories: tes (success), tec (claimed fee), tef (failure), tel (local), tem (malformed)
-```
-
-### Depth Limiting
-```cpp
-// Recursive operations use depth parameter to prevent infinite recursion
-TER checkVaultState(ReadView const& view, AccountID const& id, int depth = 0);
-if (depth > maxDepth) return tecINTERNAL;
-```
-
-## Common Pitfalls
-- Never use `read()` when you need to modify - use `peek()` instead
-- Never forget to call `view.update(sle)` after modifying a peeked SLE
-- Never use bare booleans for control flags - use the enum types
-- Always check for frozen/unauthorized states before operating on trust lines

-Provides HTTP/HTTPS client functionality for network requests, including SSL certificate registration, asynchronous request handling with boost::asio, and callback-based completion.
-
-## Key Patterns
-
-### Async HTTP with Callbacks
-```cpp
-// Callback returns bool indicating success/continuation
-HTTPClient::get(
-    bSSL, io_context,
-    std::deque<std::string>{"site1.com", "site2.com"},  // Fallback sites
-    443, "/path",
-    maxResponseBytes,
-    timeout,
-    [](boost::system::error_code const& ec, int status, std::string const& body) -> bool {
-        if (ec) return false;  // Stop
-        // Process response
-        return true;  // Success
-    },
-    headers, journal);
-```
-
-### Lifetime Management with shared_from_this
-```cpp
-// Async callbacks use intrusive_ptr for safe lifetime
-class HTTPClientImp : public HTTPClient,
-    public std::enable_shared_from_this<HTTPClientImp> {
-    void startAsync() {
-        auto self = shared_from_this();  // Prevent premature destruction
-        // ... schedule async operations ...
-    }
-};
-```
-
-### Deadline Timers
-```cpp
-// Always set timeouts for network operations
-boost::asio::basic_waitable_timer<std::chrono::steady_clock> timer_;
-timer_.expires_after(std::chrono::seconds(timeout));
-// Cancel pending operation on timeout
-```
-
-## Common Pitfalls
-- Never start async operations without capturing shared_from_this - object may be destroyed before callback
-- Always set deadline timers on network operations to prevent hanging connections
-- Always set maximum response size limits to prevent resource exhaustion
-- Never assume DNS resolution will succeed - handle resolver errors

-# Net Images Module Best Practices
-
-## Description
-Use when working with static image assets in `src/libxrpl/net/images/`. Contains embedded image data used by the HTTP server.
-
-## Responsibility
-Stores static image assets (favicons, logos) as embedded byte arrays for serving via the built-in HTTP server without external file dependencies.
-
-## Key Patterns
-
-### Embedded Assets
-```cpp
-// Images stored as static const byte arrays
-// Compiled directly into the binary - no file I/O needed at runtime
-static unsigned char const favicon[] = { /* ... */ };
-```
-
-## Common Pitfalls
-- Keep embedded images small - they increase binary size
-- Use appropriate image formats (ICO for favicons, PNG for logos)
-- Update both the source image and the byte array when changing assets

-# NodeStore Module Best Practices
-
-## Description
-Use when working with persistent node storage in `src/libxrpl/nodestore/` or `include/xrpl/nodestore/`. Covers the storage abstraction layer, backend implementations, and caching.
-
-## Responsibility
-Abstraction layer for persistent storage of ledger nodes (SHAMap leaves and inner nodes). Supports multiple backend implementations (RocksDB, NuDB, Memory, Null) with a plugin architecture, caching, and async operations.
-
-## Key Patterns
-
-### Abstract Factory for Backends
-```cpp
-// Backend is pure virtual - concrete implementations selected at runtime
-class Backend {
-    virtual ~Backend() = default;
-    virtual Status fetch(void const* key, std::shared_ptr<NodeObject>*) = 0;
-    virtual void store(std::shared_ptr<NodeObject> const&) = 0;
-    virtual void storeBatch(Batch const& batch) = 0;
-};
-// Backends: RocksDB, NuDB, Memory (testing), Null (disabled)
-```
-
-### Batch Operations
-```cpp
-// Always prefer batch operations for multiple reads/writes
-virtual std::pair<std::vector<std::shared_ptr<NodeObject>>, Status>
-    fetchBatch(std::vector<uint256 const*> const& hashes) = 0;
-virtual void storeBatch(Batch const& batch) = 0;
-// Significantly reduces I/O overhead vs individual operations
-```
-
-### Status Enum (Not Exceptions)
-```cpp
-enum class Status { ok, notFound, keyTooBig, /* ... */ };
-// I/O operations return Status, NOT throw exceptions
-auto [objects, status] = backend->fetchBatch(hashes);
-if (status != Status::ok) { /* handle */ }
-```
-
-### Configuration via Section
-```cpp
-// Backend options come from config file sections
-RocksDBBackend(int keyBytes, Section const& keyValues,
-    Scheduler& scheduler, beast::Journal journal);
-// Allows runtime tuning without recompilation
-```
-
-### Async Fetch with Scheduler
-```cpp
-// Non-blocking reads via scheduler integration
-virtual void asyncFetch(uint256 const& hash,
-    std::function<void(std::shared_ptr<NodeObject>)>&& callback);
-// Callback invoked on scheduler thread
-```
-
-## Common Pitfalls
-- Never use individual fetch/store in tight loops - use batch operations
-- Never throw exceptions from backend implementations - return Status enum
-- Always configure appropriate cache sizes for the workload
-- Never assume a fetch will succeed - always check Status
-- Use Memory backend for unit tests, never RocksDB

-# NodeStore Backend Module Best Practices
-
-## Description
-Use when working with storage backend implementations in `src/libxrpl/nodestore/backend/`. Covers RocksDB, NuDB, Memory, and Null backend factories.
-
-## Responsibility
-Concrete backend implementations for the NodeStore abstraction layer. Each backend provides persistent (or ephemeral) storage with different performance characteristics and use cases.
-
-## Key Patterns
-
-### Backend Factory Registration
-```cpp
-// Each backend is a factory that creates Backend instances
-// Registered by name in the Manager
-class RocksDBFactory : public Factory {
-    std::string getName() const override { return "RocksDB"; }
-    std::unique_ptr<Backend> createInstance(...) override;
-};
-```
-
-### RocksDB Configuration
-```cpp
-// Extensive tuning via config Section
-// Key options:
-//   open_files       - Max open file descriptors
-//   filter_bits      - Bloom filter bits per key (default 10)
-//   cache_mb         - Block cache size in MB
-//   file_size_mb     - Target SST file size
-//   compression      - snappy (default), zlib, lz4, none
-//   block_size       - Block size in KB (default 4)
-//   num_threads      - Background compaction threads
-```
-
-### NuDB for Deterministic Storage
-```cpp
-// NuDB supports deterministic initialization
-// Useful for reproducible test databases
-// Hash-based storage with direct memory-mapped I/O
-// Lower CPU overhead than RocksDB for write-heavy workloads
-```
-
-### Memory Backend for Testing
-```cpp
-// In-memory storage - fast but not persistent
-// Use for unit tests only
-// Thread-safe with internal mutex
-```
-
-### Null Backend for Disabled Storage
-```cpp
-// No-op backend - all operations succeed but store nothing
-// Use when storage feature is disabled in config
-```
-
-## Common Pitfalls
-- Use Memory backend for tests, never RocksDB (test isolation and speed)
-- Always tune RocksDB bloom filter bits - default 10 is good for most workloads
-- NuDB doesn't support range queries - only point lookups by hash
-- Never use Null backend in production - data loss guaranteed
-- Always configure appropriate open_files limits for the OS

-# Proto Module Best Practices
-
-## Description
-Use when working with Protocol Buffer definitions in `include/xrpl/proto/`. Covers gRPC API definitions and generated protobuf headers.
-
-## Responsibility
-Contains Protocol Buffer generated headers defining the gRPC API for rippled. These define the wire format for RPC communication between clients and the server.
-
-## Key Patterns
-
-### Proto Organization
-```
-include/xrpl/proto/
-└── org/xrpl/rpc/v1/
-    └── *.proto generated headers
-```
-
-### Usage
-```cpp
-#include <xrpl/proto/org/xrpl/rpc/v1/xrp_ledger.grpc.pb.h>
-// Use generated types for gRPC request/response
-```
-
-### Versioning
-- API is versioned under `org/xrpl/rpc/v1/`
-- New versions get a new directory (v2/, etc.)
-- Never modify generated files directly - modify the .proto source
-
-## Common Pitfalls
-- Never hand-edit generated .pb.h files - regenerate from .proto sources
-- Always use the versioned path (v1/) when including proto headers
-- Proto types are for serialization only - convert to native types for business logic

-# Protocol Module Best Practices
-
-## Description
-Use when working with serialization and data types in `src/libxrpl/protocol/` or `include/xrpl/protocol/`. Covers STObject hierarchy, SField registry, serialization, TER codes, features, and keylets.
-
-## Responsibility
-Defines serialization formats, data types, and protocol constants. Handles conversion between C++ objects and wire format, JSON representation, and database storage. The largest module in libxrpl with 60+ files.
-
-## Key Patterns
-
-### STObject Hierarchy
-```cpp
-// STBase is the abstract root for all serializable types
-// Concrete types: STInteger<N>, STBlob, STAmount, STArray, STObject, STPathSet, STVector256
-
-// Access fields type-safely via SField references
-auto amount = obj[sfAmount];          // Returns STAmount
-auto flags = obj[sfFlags];            // Returns uint32
-auto dest = obj[sfDestination];       // Returns AccountID
-auto has = obj.isFieldPresent(sfMemos); // Check presence
-```
-
-### SField Registry
-```cpp
-// Fields are statically registered - never create SField at runtime
-// SField carries type information and field ID
-extern SField const sfAmount;       // STAmount type
-extern SField const sfFlags;        // STInteger<uint32> type
-extern SField const sfDestination;  // STAccount type
-
-// Field IDs are protocol-defined and must not change
-```
-
-### Serializer for Binary Format
-```cpp
-// Deterministic binary serialization
-Serializer s;
-obj.add(s);              // Append binary representation
-auto blob = s.peekData(); // Get bytes
-
-// Deserialization
-SerialIter sit(blob.data(), blob.size());
-auto obj = std::make_shared<STObject>(sit, sfTransaction);
-```
-
-### Bidirectional JSON/Binary Conversion
-```cpp
-// Object to JSON
-Json::Value json = obj.getJson(JsonOptions::none);
-
-// JSON to Object
-STParsedJSONObject parsed("tx_json", json);
-if (parsed.object) { /* use parsed.object */ }
-```
-
-### TER (Transaction Error Result) Codes
-```cpp
-// Categories:
-// tes - success (tesSUCCESS)
-// tec - claimed fee, no effect (tecNO_DST, tecFROZEN, tecINSUFFICIENT_RESERVE)
-// tef - failure (tefFAILURE)
-// tel - local error (telNETWORK_ID_MAKES_TX_NON_CANONICAL)
-// tem - malformed (temINVALID, temBAD_AMOUNT, temDISABLED)
-
-// Check categories:
-isTesSuccess(ter)   // ter == tesSUCCESS
-isTecClaim(ter)     // tec range
-isTemMalformed(ter) // tem range
-```
-
-### Feature/Amendment Flags
-```cpp
-// Gate new behavior on amendments
-if (ctx.rules.enabled(featureMyFeature)) {
-    // New behavior
-} else {
-    // Legacy behavior
-}
-// Register features in Feature.cpp
-```
-
-### Keylet for Ledger Entry Keys
-```cpp
-// Type-safe ledger key generation
-auto key = keylet::account(accountID);     // Account root
-auto key = keylet::line(a, b, currency);   // Trust line
-auto key = keylet::offer(account, seq);    // Offer
-auto key = keylet::nftoken(tokenID);       // NFT
-// Keylet carries both the key (uint256) and the expected ledger entry type
-```
-
-### SOTemplate for Schema Validation
-```cpp
-// Define expected fields for a ledger entry type
-SOTemplate const ltACCOUNT_ROOT = {
-    {sfAccount, soeREQUIRED},
-    {sfBalance, soeREQUIRED},
-    {sfFlags, soeREQUIRED},
-    {sfSequence, soeREQUIRED},
-    {sfOwnerCount, soeDEFAULT},
-    // ...
-};
-```
-
-## Common Pitfalls
-- Never create SField instances at runtime - they are static protocol definitions
-- Never modify field IDs - they are part of the binary protocol
-- Always use `isFieldPresent()` before accessing optional fields
-- Never ignore TER return values - they carry critical error information
-- Always gate new fields/behavior on feature amendments for consensus safety
-- Respect JSON parsing depth limit of 10 to prevent stack overflow
-- Use `[[nodiscard]]` on functions returning TER

-# RDB Module Best Practices
-
-## Description
-Use when working with relational database access in `src/libxrpl/rdb/` or `include/xrpl/rdb/`. Covers SOCI wrapper, database configuration, and checkpointing.
-
-## Responsibility
-Provides a C++ wrapper around SOCI (SQLite/PostgreSQL abstraction) for relational data access, configuration management, blob type conversions, and periodic WAL checkpoint management.
-
-## Key Patterns
-
-### DBConfig Lazy Initialization
-```cpp
-// Construct config without opening connection
-DBConfig config(basicConfig, "my_database");
-
-// Open session later when needed
-soci::session session;
-config.open(session);
-// Allows config parsing separate from database I/O
-```
-
-### Blob Conversions
-```cpp
-// Convert between SOCI blobs and standard types
-soci::blob blob(session);
-std::vector<std::uint8_t> bytes;
-convert(blob, bytes);   // blob -> vector
-
-std::string str;
-convert(blob, str);     // blob -> string
-```
-
-### Checkpointer with Weak Pointer Safety
-```cpp
-// Checkpointer uses weak_ptr to detect session destruction
-auto checkpointer = makeCheckpointer(
-    id,
-    std::weak_ptr<soci::session>(sessionPtr),
-    jobQueue,
-    logs);
-checkpointer->schedule();  // Periodic WAL checkpoints
-// If session is destroyed, checkpointer safely no-ops
-```
-
-### Thread-Safe Sessions
-```cpp
-// Each thread gets its own soci::session from the pool
-// Never share a soci::session across threads
-```
-
-## Common Pitfalls
-- Never share a soci::session across threads - each thread needs its own
-- Always use `std::weak_ptr` for session references in long-lived objects (like Checkpointer)
-- Be aware of SOCI include warnings - use pragma diagnostic push/pop
-- Always convert blobs to standard types before processing

-
-## Responsibility
-Tracks resource consumption by network endpoints (inbound/outbound connections) to prevent abuse and ensure fair resource allocation. Manages consumer lifecycle, charge accounting, and gossip-based reputation sharing.
-
-## Key Patterns
-
-### Manager/Impl Pattern
-```cpp
-// Abstract Manager interface with factory function
-class Manager { virtual ~Manager() = 0; };
-std::unique_ptr<Manager> make_Manager(beast::Journal journal);
-
-// Implementation hidden in cpp
-class ManagerImp : public Manager { /* ... */ };
-```
-
-### Consumer Factory
-```cpp
-// Different consumer types for different connection sources
-Consumer newInboundEndpoint(beast::IP::Endpoint const& address);
-Consumer newOutboundEndpoint(beast::IP::Endpoint const& address);
-Consumer newUnlimitedEndpoint(beast::IP::Endpoint const& address);
-```
-
-### Background Thread Shutdown
-```cpp
-// Clean shutdown pattern with condition variable
-~ManagerImp() {
-    {
-        std::lock_guard lock(mutex_);
-        stop_ = true;
-        cond_.notify_one();
-    }
-    thread_.join();  // Wait for thread to finish
-}
-```
-
-### Proxy-Aware Endpoint Detection
-```cpp
-// Handle forwarded-for headers safely
-boost::system::error_code ec;
-auto proxiedIp = boost::asio::ip::make_address(forwardedFor, ec);
-if (ec) {
-    journal_.warn() << "Invalid IP: " << ec.message();
-    return newInboundEndpoint(address);  // Fallback to socket IP
-}
-```
-
-## Common Pitfalls
-- Never trust forwarded-for headers without proxy flag validation
-- Always use the factory methods - never construct Consumer directly
-- Always join background threads in destructor

-
-## Description

-
-## Responsibility
-Manages server listening ports, WebSocket configuration, SSL/TLS setup, authentication credentials, and admin network restrictions. Handles parsing configuration into validated port structures.
-
-## Key Patterns
-
-### Dual ParsedPort/Port Pattern
-```cpp
-// ParsedPort: intermediate parsing result (may be incomplete)
-struct ParsedPort { /* partially validated fields */ };
-
-// Port: final validated configuration (ready to use)
-struct Port {
-    std::string name;
-    boost::asio::ip::address ip;
-    std::uint16_t port = 0;
-    std::set<std::string, iless> protocol;
-    // ...
-};
-```
-
-### Configuration Section Parsing
-```cpp
-// Parse from config file section, log errors to stream
-void parse_Port(ParsedPort& port, Section const& section, std::ostream& log);
-// Does NOT throw - logs issues and sets defaults
-```
-
-### CIDR Admin Networks
-```cpp
-// IP-based admin access control with CIDR support
-std::vector<boost::asio::ip::network_v4> admin_nets_v4;
-std::vector<boost::asio::ip::network_v6> admin_nets_v6;
-// Supports both IPv4 and IPv6 ranges
-```
-
-### WebSocket Options
-```cpp
-// Fine-grained compression control
-boost::beast::websocket::permessage_deflate pmd_options;
-// Queue limits prevent memory exhaustion
-std::optional<std::uint16_t> ws_queue_limit;
-// limit=0 means unlimited (not -1)
-```
-
-### SSL Context Lazy Creation
-```cpp
-// SSL context created only when needed
-std::shared_ptr<boost::asio::ssl::context> context;
-// Initialized when first SSL connection established
-```
-
-## Common Pitfalls
-- Never use port-only access control - always use CIDR network restrictions for admin
-- Use `iless` comparator for protocol names (case-insensitive)

-- Always log parsing errors rather than throwing

-# SHAMap Module Best Practices
-
-## Description
-Use when working with the Merkle tree implementation in `src/libxrpl/shamap/` or `include/xrpl/shamap/`. Covers the SHA-256 based radix tree used for ledger state representation.
-
-## Responsibility
-Implements a SHA-256 based Merkle radix tree with 16-way branching (hexadecimal). Provides efficient ledger state representation with O(log N) proof-of-inclusion, copy-on-write snapshots, synchronization, and delta calculation.
-
-## Key Patterns
-
-### State Machine Lifecycle
-```cpp
-enum class SHAMapState { Modifying, Immutable, Synching, Invalid };
-// Modifying: Can add/remove/modify entries
-// Immutable: Snapshot - no modifications allowed
-// Synching: Being synchronized from peers
-// Invalid: Corrupted or destroyed
-// Transitions are one-way: Modifying -> Immutable (via snapshot)
-```
-
-### Copy-on-Write via COWID
-```cpp
-std::uint32_t cowid_ = 1;
-// Each snapshot gets a new COWID
-// Children are only copied when modified (lazy copy)
-// Immutable snapshots share nodes with the active map
-auto snapshot = map.snapShot(true);  // Creates immutable copy
-```
-
-### 16-Way Radix Branching
-```cpp
-static inline constexpr unsigned int branchFactor = 16;
-static inline constexpr unsigned int leafDepth = 64;
-// 256-bit key / 4 bits per nibble = 64 levels max
-// Each inner node has up to 16 children
-```
-
-### Node Type Hierarchy
-```cpp
-// SHAMapTreeNode (base) -> SHAMapInnerNode (16 children)
-//                       -> SHAMapLeafNode (data + key)
-// Use dynamic_pointer_cast for safe downcasting
-auto inner = intr_ptr::dynamic_pointer_cast<SHAMapInnerNode>(node);
-if (inner) { /* process inner node */ }
-```
-
-### Walk-Up for Modifications (dirtyUp)
-```cpp
-// After modifying a leaf, propagate hash changes to root
-void dirtyUp(SharedPtrNodeStack& stack, uint256 const& target, ...);
-// Updates hashes from leaf -> root through the stack
-```
-
-### Lazy Traversal
-```cpp
-// Navigate to a leaf by key
-SHAMapLeafNode* walkTowardsKey(uint256 const& id,
-    SharedPtrNodeStack* stack = nullptr);
-// Returns leaf or nullptr; optionally records path for dirtyUp
-```
-
-### Intrusive Pointers for Nodes
-```cpp
-// Nodes use intrusive reference counting (not std::shared_ptr)
-intr_ptr::SharedPtr<SHAMapTreeNode> root_;
-// Minimal overhead - reference count embedded in node
-```
-
-## Common Pitfalls
-- Never modify an Immutable map - check state before mutations
-- Always call dirtyUp after modifying a leaf to maintain hash integrity
-- Never assume node type without dynamic_pointer_cast check
-- Remember that snapshots share nodes - COW means nodes are only copied on write
-- Always use the provided iterators for safe traversal, not manual tree walking

-# Transaction (tx) Module Best Practices

-## Description
-Use when working with transaction processing in `src/libxrpl/tx/` or `include/xrpl/tx/`. Covers the Transactor base class, transaction pipeline, invariant checks, and apply context.
-
-## Responsibility
-Implements the transaction processing pipeline: static validation (preflight), fee-claim checks (preclaim), transaction execution (doApply), and post-apply invariant verification. All transaction types derive from the Transactor base class.
-
-## Key Patterns
-
-### Transaction Pipeline (3 Phases)
-```cpp

-    if (ctx.tx[sfAmount] <= beast::zero)
-        return temBAD_AMOUNT;

-```cpp
-static bool checkExtraFeatures(PreflightContext const& ctx) {
-    // Return false to disable when amendment not enabled
-    return ctx.rules.enabled(featureMyFeature);
-}
-```
-
-### Flag Validation
-```cpp
-static std::uint32_t getFlagsMask(PreflightContext const& ctx) {
-    return tfMyTransactionMask;  // Allowed flags
-}
-// Base class validates: (tx.getFlags() & ~getFlagsMask()) == 0
-```
-
-### ConsequencesFactory Types
-```cpp
-// Normal: Standard transaction
-static constexpr ConsequencesFactoryType ConsequencesFactory{Normal};
-// Blocker: Affects subsequent transactions' ability to claim fees
-static constexpr ConsequencesFactoryType ConsequencesFactory{Blocker};
-// Custom: Override makeTxConsequences() static method
-static constexpr ConsequencesFactoryType ConsequencesFactory{Custom};
-```
-
-### TER Error Code Progression
-```
-tem* (malformed):  temINVALID, temBAD_AMOUNT, temDISABLED - preflight errors
-tef* (failure):    tefFAILURE, tefNESTED_FAILURE - infrastructure errors
-tel* (local):      telNETWORK_ID_MAKES_TX_NON_CANONICAL - local-only errors
-tec* (claimed):    tecNO_DST, tecFROZEN, tecINSUFFICIENT_RESERVE - fee claimed, no effect
-tes  (success):    tesSUCCESS - transaction applied
-```
-
-### Logging Convention
-```cpp
-JLOG(ctx.j.warn()) << "User error message";    // User-facing issues
-JLOG(ctx.j.debug()) << "Detailed diagnostic";  // Implementation details
-JLOG(ctx.j.trace()) << "Very verbose info";     // Deep debugging
-JLOG(ctx.j.error()) << "Unexpected failure";    // Should not happen
-```
-
-### View Operations in doApply
-```cpp
-// Read-only (returns const SLE)
-auto sle = view().read(keylet::account(accountID));
-
-// Mutable (returns non-const SLE)
-auto sle = view().peek(keylet::account(accountID));
-sle->setFieldAmount(sfBalance, newBalance);
-view().update(sle);  // MUST call after modification
-
-// Create new entry
-auto sle = std::make_shared<SLE>(keylet::myEntry(id));
-sle->setFieldText(sfData, data);
-view().insert(sle);
-
-// Remove entry
-view().erase(sle);
-```
-
-## Common Pitfalls
-- Never access ledger state in preflight - it only has PreflightContext (no view)
-- Never mutate ledger state in preclaim - it has ReadView only
-- Always call `view().update(sle)` after modifying a peeked SLE
-- Never return `tesSUCCESS` from preclaim/preflight if validation failed
-- Always gate new transaction types on feature amendments
-- Use `NotTEC` return type for preflight (not TER) - prevents returning tec codes from static checks
-- Never forget to register new transaction types in `transactions.macro` and `applySteps.cpp`

-# Transaction Paths Module Best Practices
-
-## Description
-Use when working with payment path finding and execution in `src/libxrpl/tx/paths/` or `include/xrpl/tx/paths/`. Covers the flow engine, ripple calculation, and offer stream processing.
-
-## Responsibility
-Implements payment path finding and execution for cross-currency payments. Handles the flow engine for executing payments across multiple paths (strands), offer book management, and amount calculation.
-
-## Key Patterns
-
-### Flow Engine Entry Point
-```cpp
-path::RippleCalc::Output flow(
-    PaymentSandbox& view,
-    STAmount const& deliver,
-    AccountID const& src,
-    AccountID const& dst,
-    STPathSet const& paths,
-    bool defaultPaths,
-    bool partialPayment,
-    bool ownerPaysTransferFee,
-    OfferCrossing offerCrossing,
-    std::optional<Quality> const& limitQuality,
-    std::optional<STAmount> const& sendMax,
-    std::optional<uint256> const& domainID,
-    beast::Journal j,
-    path::detail::FlowDebugInfo* flowDebugInfo = nullptr);
-```
-
-### Strand-Based Execution
-```cpp
-// A "strand" is a single payment path through the DEX
-// Multiple strands can be tried to find the best rate
-// StrandFlow executes a single strand
-// Flow tries all strands and picks the best result
-```
-
-### OfferStream for Order Book Processing
-```cpp
-// Iterates through offers in an order book
-// Handles expired offers, unfunded offers, and self-crossing
-// Automatically cleans up stale offers during traversal
-```
-
-### Quality-Based Routing
-```cpp
-// Quality = exchange rate between input and output
-// Lower quality number = better rate
-// limitQuality prevents accepting rates worse than threshold
-```
-
-### PaymentSandbox Isolation
-```cpp
-// All path calculations happen in a PaymentSandbox
-// Changes are only committed if the payment succeeds
-// Allows trying multiple paths without side effects
-```
-
-## Common Pitfalls
-- Never modify the ledger directly during path calculation - use PaymentSandbox
-- Always respect limitQuality to prevent unfavorable exchange rates
-- Be aware that offer traversal may clean up stale offers as a side effect
-- FlowDebugInfo is optional and only for debugging - never rely on it in production logic
-- Path finding is computationally expensive - respect depth and complexity limits
-

-# Transactors Module Best Practices
-
-## Description
-Use when adding or modifying transaction types in `src/libxrpl/tx/transactors/`. This is the guide for implementing new transactors following the established patterns.
-
-## Responsibility
-Contains all concrete transaction type implementations. Each transactor follows the Transactor base class pattern with preflight/preclaim/doApply phases. Transaction types are organized by feature area in subdirectories.
-
-## Template for New Transactors
-
-### Header File (`include/xrpl/tx/transactors/MyTx.h`)
-```cpp
-#pragma once
-#include <xrpl/tx/Transactor.h>
-
-namespace xrpl {
-
-class MyTransaction : public Transactor {
-public:
-    static constexpr ConsequencesFactoryType ConsequencesFactory{Normal};
-
-    explicit MyTransaction(ApplyContext& ctx) : Transactor(ctx) {}
-
-    static bool checkExtraFeatures(PreflightContext const& ctx);

-    static NotTEC preflight(PreflightContext const& ctx);
-    static TER preclaim(PreclaimContext const& ctx);
-    TER doApply() override;
-};

-    sle->setFieldAmount(sfBalance, newBalance);
-    view().update(sle);
-
-    return tesSUCCESS;
-}
-
-}
-```
-
-### Registration Checklist
-1. Add transaction type to `include/xrpl/protocol/detail/transactions.macro`
-2. Add dispatch case to `src/libxrpl/tx/applySteps.cpp`
-3. Add feature flag to `include/xrpl/protocol/Feature.h` and `src/libxrpl/protocol/Feature.cpp`
-4. Add invariant checks if needed in `src/libxrpl/tx/InvariantCheck.cpp`
-5. Add to `disabledTxTypes` in Batch.cpp if not batch-compatible
-
-## Key Patterns Across All Transactors
-
-### Feature Gating
-```cpp
-static bool checkExtraFeatures(PreflightContext const& ctx) {
-    return ctx.rules.enabled(featureMyFeature);
-}
-```
-
-### Variant-Aware Validation
-```cpp
-// When handling Asset (Issue or MPTIssue):
-if (auto const ret = std::visit(
-    [&]<typename T>(T const&) { return preflightHelper<T>(ctx); },
-    ctx.tx[sfAmount].asset().value()); !isTesSuccess(ret))
-    return ret;
-```
-
-### Ledger Entry CRUD in doApply
-```cpp
-// Create
-auto sle = std::make_shared<SLE>(keylet::myEntry(id));
-view().insert(sle);
-
-// Read (mutable)
-auto sle = view().peek(keylet::myEntry(id));
-
-// Update
-sle->setFieldU32(sfFlags, newFlags);
-view().update(sle);
-
-// Delete
-view().erase(sle);
-```
-
-### Helper/Utils Files
-```cpp
-// Complex features use a separate Helpers/Utils file:
-// AMM -> AMMHelpers.h, AMMUtils.h
-// NFT -> NFTokenUtils.h
-// Lending -> LendingHelpers.h
-// Keep reusable logic in helpers, transaction-specific logic in transactors
-```
-
-## Common Pitfalls
-- Never forget to register in `transactions.macro` and `applySteps.cpp`
-- Never access ledger state in preflight (no view available)
-- Never mutate state in preclaim (read-only view)
-- Always call `view().update(sle)` after modifying a peeked entry
-- Always gate on feature amendment for consensus safety
-- Use `NotTEC` return type from preflight, `TER` from preclaim/doApply
-- Put shared logic in a *Helpers.h file, not duplicated across transactors

-# AMM (Automated Market Maker) Transactors Best Practices
-
-## Description
-Use when working with AMM transaction types in `src/libxrpl/tx/transactors/AMM/`. Covers pool creation, deposits, withdrawals, voting, bidding, deletion, and clawback.
-
-## Responsibility
-Implements decentralized trading pools with liquidity provider (LP) tokens. Allows users to create AMM pools, deposit/withdraw liquidity, vote on trading fees, bid on auction slots, and manage pool lifecycle.
-
-## Key Patterns
-
-### AMM Transaction Types
-- **AMMCreate** - Create a new AMM pool with two assets
-- **AMMDeposit** - Add liquidity to a pool, receive LP tokens
-- **AMMWithdraw** - Remove liquidity, burn LP tokens
-- **AMMVote** - Vote on trading fee percentage
-- **AMMBid** - Bid on the auction slot for discounted trading
-- **AMMDelete** - Remove an empty AMM pool
-- **AMMClawback** - Issuer clawback of assets from AMM
-
-### Precision Arithmetic
-```cpp
-// AMM calculations require controlled rounding
-// ALWAYS use NumberRoundModeGuard for rounding control
-NumberRoundModeGuard mg(Number::towards_zero);
-auto lpTokens = ammLPTokens(amount1, amount2, lptIssue);
-
-// Or explicit mode changes with RAII save
-{
-    saveNumberRoundMode _{Number::getround()};
-    Number::setround(Number::upward);
-    auto value = calculation;
-}
-```
-
-### Helper Functions (AMMHelpers.h)
-```cpp
-ammLPTokens()             // Calculate LP tokens from pool reserves
-lpTokensOut()             // LP tokens from deposit
-ammAssetIn() / ammAssetOut() // Calculate swap amounts
-withinRelativeDistance()   // Quality tolerance checks
-changeSpotPriceQuality()  // Quote generation algorithm
-// Quadratic equation solving for pricing
-```
-
-### Feature Gates
-```cpp
-// Multiple amendment versions
-ammEnabled(ctx.rules)     // Base AMM feature
-fixAMMv1_1                // First fix amendment
-fixAMMv1_3                // Third fix amendment
-// Always check which amendments are active
-```
-
-## Common Pitfalls
-- Never perform AMM math without setting the rounding mode first
-- Always use `NumberRoundModeGuard` (RAII) - never manually set/restore rounding
-- Be aware that AMM calculations involve quadratic equations - precision matters
-- AMMClawback has different authorization requirements than regular clawback
-- Check `withinRelativeDistance` for quality tolerance rather than exact equality

-# Check Transactors Best Practices
-
-## Description
-Use when working with Check transaction types in `src/libxrpl/tx/transactors/Check/`. Covers check creation, cashing, and cancellation.
-
-## Responsibility
-Implements a check-like payment mechanism (delayed payment authorization). A sender creates a check, the recipient cashes it, and either party can cancel it (with expiration support).
-
-## Key Patterns
-
-### Check Lifecycle
-```cpp
-// 1. CreateCheck - Sender authorizes payment
-//    Validates: destination exists, amount valid, expiration future
-//    Creates: Check ledger entry with sender, destination, amount
-
-// 2. CashCheck - Recipient claims payment
-//    Validates: caller is destination, check not expired
-//    Executes: transfers funds from sender to destination
-
-// 3. CancelCheck - Either party cancels
-//    Validates: caller is sender or destination, or check expired
-//    Removes: Check ledger entry
-```
-
-### Error Codes
-```cpp
-tecNO_DST         // Destination account doesn't exist
-temREDUNDANT      // Check to self
-temBAD_AMOUNT     // Invalid amount
-temBAD_EXPIRATION // Expiration in the past
-tecEXPIRED        // Check has expired (for CashCheck)
-```
-
-## Common Pitfalls
-- Checks can be cancelled by either sender or destination
-- Expired checks can be cancelled by anyone
-- CashCheck must handle both exact amount and "deliver minimum" modes
-- Always validate expiration against the parent ledger close time

-# Delegate Transactors Best Practices

-## Description
-Use when working with delegation transaction types in `src/libxrpl/tx/transactors/Delegate/`. Covers delegate set and utilities.
-
-## Responsibility
-Manages transaction signing delegation, allowing accounts to authorize other accounts to sign transactions on their behalf without exposing the master key.
-
-## Key Patterns
-
-### Delegate Operations
-```cpp
-// DelegateSet - Create or modify a delegation
-// Validates: delegate account exists, permissions valid
-// Creates/Updates: Delegate ledger entry
-
-// DelegateUtils - Shared utilities
-// deleteDelegate() - Public cleanup interface, used by DeleteAccount
-```
-
-### Feature Gates

-// fixDelegateV1_1 - Added data existence checks
-if (ctx.rules.enabled(fixDelegateV1_1)) {

-### Integration with DeleteAccount
-```cpp
-// DelegateUtils::deleteDelegate() is called by DeleteAccount
-// for cleanup when an account is being deleted
-// Must handle all delegation-related ledger entries
-```

-# Lending Transactors Best Practices
-
-## Description
-Use when working with lending protocol transaction types in `src/libxrpl/tx/transactors/Lending/`. Covers loan management, broker operations, and payment calculation.
-
-## Responsibility
-Implements a complex loan protocol with amortization schedules, interest calculation, broker management, and collateral handling. The largest transactor feature area by code volume.
-
-## Key Patterns
-
-### Loan Lifecycle
-```cpp
-// LoanSet     - Create or configure a loan
-// LoanPay     - Make loan payments (principal + interest)
-// LoanManage  - Manage loan state transitions
-// LoanDelete  - Remove a completed/cancelled loan
-```
-
-### Broker Operations
-```cpp
-// LoanBrokerSet          - Create/configure a broker
-// LoanBrokerDelete       - Remove a broker
-// LoanBrokerCoverDeposit - Deposit collateral
-// LoanBrokerCoverWithdraw - Withdraw collateral
-// LoanBrokerCoverClawback - Clawback broker assets
-```
-
-### Payment Calculation (LendingHelpers.h)
-```cpp
-struct LoanPaymentParts {
-    Number principalPaid;    // Reduces loan balance
-    Number interestPaid;     // Goes to Vault
-    Number valueChange;      // Loan value adjustment
-    Number feePaid;          // Goes to Broker
-};
-
-// Key helper functions:
-checkLendingProtocolDependencies()  // Validate feature gates
-loanPeriodicRate()                  // Interest with secondsInYear
-roundPeriodicPayment()              // Consistent rounding
-```
-
-### Feature Gate
-```cpp
-// All lending operations gated on single feature
-ctx.rules.enabled(featureLendingProtocol)
-```
-
-### Batch Transaction Restriction
-```cpp
-// Lending transactions are DISABLED in batch transactions
-// Listed in Batch::disabledTxTypes
-// Cannot be included in atomic batch operations
-```
-
-## Common Pitfalls
-- Lending is disabled in Batch transactions - do not try to batch lending ops
-- Payment calculations require precise rounding - use LendingHelpers functions
-- Always validate lending protocol dependencies before operations
-- Interest calculation uses `secondsInYear` constant - be aware of leap year handling
-- LendingHelpers.h is ~1800 lines - the most complex helper file in the codebase

-# MPT (Multi-Purpose Token) Transactors Best Practices
-
-## Description
-Use when working with MPT transaction types in `src/libxrpl/tx/transactors/MPT/`. Covers token issuance creation, configuration, destruction, and authorization.
-
-## Responsibility
-Implements Multi-Purpose Token (MPT) operations - a fungible token system simpler than full IOU trust lines. Handles token issuance lifecycle and holder authorization.
-
-## Key Patterns
-
-### MPT Transaction Types
-```cpp
-// MPTokenIssuanceCreate  - Create a new token issuance
-// MPTokenIssuanceSet     - Modify issuance settings
-// MPTokenIssuanceDestroy - Destroy an issuance (if no holders)
-// MPTokenAuthorize       - Authorize/deauthorize a holder
-```
-
-### MPT vs IOU Trust Lines
-```cpp
-// MPT is simpler than IOU trust lines:
-// - No rippling mechanics
-// - No transfer fees between holders (only issuer)
-// - Simpler authorization model
-// - Uses MPTIssue instead of Issue
-// - Uses MPTAmount instead of IOUAmount
-```
-
-### Feature Gate
-```cpp
-ctx.rules.enabled(featureMPTokensV1)
-```
-
-### Asset Variant Handling
-```cpp
-// MPTIssue is part of the Asset variant (Issue | MPTIssue)
-// Use std::visit when handling Asset generically:
-std::visit([&](auto const& issue) {
-    // Works for both Issue and MPTIssue
-}, asset.value());
-```
-
-## Common Pitfalls
-- MPT issuances cannot be destroyed if any holders exist
-- Authorization is per-holder, not per-token
-- Don't confuse MPTIssue with Issue - they have different keylet types
-- Always check `featureMPTokensV1` before MPT operations

-# NFT (Non-Fungible Token) Transactors Best Practices
-
-## Description
-Use when working with NFT transaction types in `src/libxrpl/tx/transactors/NFT/`. Covers minting, burning, offer management, and token modification.
-
-## Responsibility
-Implements NFT creation, trading, and lifecycle management. Handles token minting, burning, buy/sell offer creation and acceptance, offer cancellation, and dynamic NFT modification.
-
-## Key Patterns
-
-### NFT Transaction Types
-```cpp
-// NFTokenMint        - Create a new NFT
-// NFTokenBurn        - Destroy an NFT
-// NFTokenCreateOffer - Create a buy or sell offer
-// NFTokenCancelOffer - Cancel an existing offer
-// NFTokenAcceptOffer - Accept a buy or sell offer (execute trade)
-// NFTokenModify      - Modify NFT metadata (dynamic NFTs)
-```
-
-### NFTokenUtils - Shared Utilities (~1025 lines)
-```cpp
-// Key utility functions:
-findToken()              // Find an NFT in owner's token pages
-insertToken()            // Add NFT to owner's directory
-removeToken()            // Remove NFT from owner's directory
-deleteTokenOffer()       // Clean up a single offer
-removeTokenOffersWithLimit() // Batch cleanup with limit
-notTooManyOffers()       // Check offer count limits
-changeTokenURI()         // Update NFT URI (dynamic NFTs)
-
-struct TokenAndPage {
-    STObject token;
-    std::shared_ptr<SLE> page;
-};
-```
-
-### Token Storage in Pages
-```cpp
-// NFTs are stored in paginated directories
-// Each page holds multiple tokens
-// Pages are linked as a doubly-linked list
-// insertToken/removeToken manage page splits and merges
-```
-
-### Feature Gates
-```cpp
-featureNFTokenMintOffer         // Combined mint + offer
-fixRemoveNFTokenAutoTrustLine   // Fix for auto trust line removal
-featureDynamicNFT               // NFTokenModify support
-```
-
-### Offer Directory Structure
-```cpp
-// Buy offers and sell offers stored in separate directories
-// Indexed by token ID
-// Offers can have expiration times
-// Offers can specify a destination (private offers)
-```
-
-## Common Pitfalls
-- Token page management is complex - always use NFTokenUtils functions
-- Offer cleanup has limits (`removeTokenOffersWithLimit`) - don't assume all offers removed
-- `notTooManyOffers()` must be checked before creating new offers
-- Dynamic NFT modification requires `featureDynamicNFT` amendment
-- Transfer fees only apply when the NFT issuer is not a party to the trade
-- Burning an NFT with outstanding offers requires offer cleanup

-# Offer Transactors Best Practices
-
-## Description
-Use when working with DEX offer transaction types in `src/libxrpl/tx/transactors/Offer/`. Covers order creation and cancellation on the native decentralized exchange.
-
-## Responsibility
-Implements decentralized exchange order management for the native XRPL order book. Handles offer creation (with matching/crossing), cancellation, and order book management.
-
-## Key Patterns
-
-### Offer Transaction Types
-```cpp
-// CreateOffer (~854 lines) - Create a new DEX order
-//   - Validates amounts, currency pairs, account state
-//   - Attempts to cross with existing offers (matching engine)
-//   - Remaining amount becomes a standing order if not fully filled
-//   - Handles self-crossing, expired offers, unfunded offers
-
-// CancelOffer - Remove an existing order
-//   - Validates caller owns the offer
-//   - Removes offer from order book directory
-```
-
-### Offer Crossing (Matching Engine)
-```cpp
-// CreateOffer performs offer crossing inline:
-// 1. Look up existing offers on the opposite side
-// 2. Match at the offer's quality (exchange rate)
-// 3. Consume matched offers (partial or full)
-// 4. Place remaining amount as standing order
-// This is the core DEX matching engine
-```
-
-### Quality and Order Books
-```cpp
-// Quality = exchange rate between TakerPays and TakerGets
-// Order books indexed by currency pair and sorted by quality
-// Lower quality number = better rate for taker
-```
-
-### Ticket Support
-```cpp
-// Offers can use tickets for sequence management
-// Feature gate: featureTickets
-```
-
-## Common Pitfalls
-- CreateOffer is one of the most complex transactors (~854 lines) - be thorough with changes
-- Offer crossing modifies multiple ledger entries atomically
-- Self-crossing (same account on both sides) has special handling
-- Expired and unfunded offers are cleaned up during crossing
-- Always validate that TakerPays and TakerGets are different assets

-# PermissionedDomain Transactors Best Practices
-
-## Description
-Use when working with permissioned domain transaction types in `src/libxrpl/tx/transactors/PermissionedDomain/`. Covers domain-based access control for the DEX.
-
-## Responsibility
-Implements domain-based access control for permissioned DEX operations. Allows creating and deleting permissioned domains that gate who can participate in certain trading activities.
-
-## Key Patterns
-
-### PermissionedDomain Transaction Types
-```cpp
-// PermissionedDomainSet    - Create or update a permissioned domain
-// PermissionedDomainDelete - Remove a permissioned domain
-```
-
-### Integration with Payments

-// Payments can reference a domain via sfDomainID field
-// The domain gates which accounts can participate
-// Used for regulated/permissioned trading environments
-```
-
-### Feature Gate
-```cpp
-ctx.rules.enabled(featurePermissionedDEX)
-```
-
-## Common Pitfalls
-- Domains are referenced by other transactions (Payments) - deletion must check for references
-- Always validate the feature gate before domain operations

-# Vault Transactors Best Practices
-
-## Description
-Use when working with vault transaction types in `src/libxrpl/tx/transactors/Vault/`. Covers vault creation, configuration, deposits, withdrawals, deletion, and clawback.
-
-## Responsibility
-Implements the vault mechanism for asset holding and loan collateral management. Allows creating vaults, depositing/withdrawing assets, configuring vault parameters, and managing vault lifecycle.
-
-## Key Patterns
-
-### Vault Transaction Types
-```cpp
-// VaultCreate   - Create a new vault
-// VaultSet      - Configure vault parameters
-// VaultDelete   - Remove an empty vault
-// VaultDeposit  - Deposit assets into a vault
-// VaultWithdraw - Withdraw assets from a vault
-// VaultClawback - Issuer clawback from vault
-```
-
-### Feature Gate
-```cpp
-ctx.rules.enabled(featureSingleAssetVault)
-```
-
-### Batch Transaction Restriction
-```cpp
-// Vault transactions are DISABLED in batch transactions
-// Listed in Batch::disabledTxTypes alongside Lending
-// Cannot be included in atomic batch operations
-```
-
-### Depth Limiting for Recursive Operations
-```cpp
-// Vault operations may involve recursive state checks
-// Use depth parameter to prevent infinite recursion
-TER checkVaultState(ReadView const& view, AccountID const& id, int depth = 0);
-if (depth > maxDepth) return tecINTERNAL;
-```
-
-### Integration with Lending
-```cpp
-// Vaults serve as collateral for the lending protocol
-// VaultDeposit/Withdraw affect loan collateralization
-// Vault state changes may trigger loan state recalculation
-```
-
-## Common Pitfalls
-- Vault operations are disabled in batch transactions
-- Vaults can only be deleted when empty
-- Clawback has different authorization requirements than regular withdrawal
-- Always respect depth limits in recursive vault state checks
-- Vault operations may interact with lending protocol state

-# Merge Conflict Resolution Guide
-
-## Description
-Use when resolving merge conflicts after merging `develop` into a feature branch. Covers the key files that commonly conflict, field number allocation, namespace conventions, and the correct resolution strategy for each file type.
-
-## General Principles
-
-### Namespace
-- All code uses `namespace xrpl { }` (not `ripple`). If a conflict shows `namespace ripple`, take the `xrpl` version.
-- Qualified references: `xrpl::sign(...)`, `xrpl::sha256_hasher`, etc. Never `ripple::`.
-
-### Header Guards
-- Always `#pragma once`. Never `#ifndef` include guards. If a conflict shows old-style guards, take the `#pragma once` version.
-
-### Copyright Headers
-- The `develop` branch has removed copyright/license comment blocks from source files. If a conflict is just about the copyright header, take `develop`'s version (no header).
-
-### File Moves
-- Many files have been moved from `src/xrpld/` to `src/libxrpl/` or from `src/xrpld/` headers to `include/xrpl/`. If git shows a file as "deleted in develop" but it exists at a new path, delete the old-path file (`git rm`) and keep the new-path version.
-- Common moves:
-  - `src/xrpld/app/tx/detail/*.h` → `include/xrpl/tx/transactors/*.h`
-  - `src/xrpld/app/tx/detail/*.cpp` → `src/libxrpl/tx/*.cpp` or `src/libxrpl/tx/transactors/*.cpp`
-  - `src/xrpld/app/tx/detail/InvariantCheck.cpp` → `src/libxrpl/tx/invariants/InvariantCheck.cpp`
-
-### Transactor Migration
-When merging transactors from `src/xrpld/app/tx/detail/` into `develop`, they must be fully migrated to the new libxrpl structure:
-
-**File locations:**
-- Header: `src/xrpld/app/tx/detail/Foo.h` → `include/xrpl/tx/transactors/Foo.h`
-- Source: `src/xrpld/app/tx/detail/Foo.cpp` → `src/libxrpl/tx/transactors/Foo.cpp`
-- Delete the old `.cpp` (both `src/xrpld/` and `src/libxrpl/` are GLOB_RECURSE discovered — duplicates cause linker errors)
-- Optionally leave a forwarding header at the old `.h` location: `#include <xrpl/tx/transactors/Foo.h>`
-
-**Header changes:**
-- `#pragma once` (not `#ifndef` guards)
-- `namespace xrpl` (not `ripple`)
-- `#include <xrpl/tx/Transactor.h>` (not `<xrpld/app/tx/detail/Transactor.h>`)
-
-**Source changes:**
-- `namespace xrpl` (not `ripple`)
-- `#include <xrpl/tx/transactors/Foo.h>` (not `<xrpld/app/tx/detail/Foo.h>`)
-- `#include <xrpl/ledger/ApplyView.h>` (not `<xrpld/ledger/ApplyView.h>`)
-- `#include <xrpl/ledger/View.h>` for `describeOwnerDir`
-
-**API changes in the new Transactor:**
-- `preflight1()` and `preflight2()` are **private** — transactor `preflight()` must NOT call them. The framework calls them automatically.
-- Flag checking (`tfUniversalMask`) is handled by the framework via `getFlagsMask()`. Override `getFlagsMask()` only if custom flag handling is needed; otherwise the default handles `tfUniversalMask`.
-- A simple `preflight()` that only did flag checks + preflight1/preflight2 should just `return tesSUCCESS;`
-- `ctx_.app.journal(...)` → `ctx_.registry.journal(...)`
-- `ctx_.app` does not exist in the new `ApplyContext`; use `ctx_.registry` for service access
-
-**transactions.macro entry:**
-Every transactor must have a `#if TRANSACTION_INCLUDE` block:
-```cpp
-#if TRANSACTION_INCLUDE
-#   include <xrpl/tx/transactors/Foo.h>
-#endif
-TRANSACTION(ttFOO, <number>, Foo, ...)
-```
-
-### Include Paths
-- `develop` uses the new macro-based transactor include system via `transactions.macro` with `TRANSACTION_INCLUDE`. Old-style explicit `#include <xrpld/app/tx/detail/*.h>` lists should be replaced with the macro approach.
-
-## File-Specific Resolution Rules
-
-### `include/xrpl/protocol/detail/features.macro`
-
-New feature amendments go **at the top** of the active list (below the macro guard checks and `// clang-format off`), in reverse chronological order.
-
-```
-// Add new amendments to the top of this list.
-// Keep it sorted in reverse chronological order.
-
-XRPL_FEATURE(MyNewFeature,              Supported::yes, VoteBehavior::DefaultNo)
-XRPL_FIX    (ExistingFix,               Supported::yes, VoteBehavior::DefaultNo)
-...
-```
-
-Resolution: Keep both sides' new amendments. Place your feature branch's new amendments at the very top.
-
-### `include/xrpl/protocol/detail/sfields.macro`
-
-Fields are grouped by type (UINT32, UINT64, UINT128, etc.) with common and uncommon sections. Each field has a unique **type + field number** pair.
-
-**Resolution strategy:**
-1. Keep both sides' new fields.
-2. Check for field number collisions within each type. Use the next available number for your feature's fields.
-3. Common fields come first, uncommon fields after (there's a comment separator).
-
-To find the next available field number for a type:
-```bash
-grep "TYPED_SFIELD.*UINT32" include/xrpl/protocol/detail/sfields.macro | sed 's/.*UINT32, *//;s/).*//' | sort -n
-```
-
-Similarly for OBJECT and ARRAY types (using `UNTYPED_SFIELD`):
-```bash
-grep "UNTYPED_SFIELD.*OBJECT" include/xrpl/protocol/detail/sfields.macro | sed 's/.*OBJECT, *//;s/).*//' | sort -n
-grep "UNTYPED_SFIELD.*ARRAY" include/xrpl/protocol/detail/sfields.macro | sed 's/.*ARRAY, *//;s/).*//' | sort -n
-```
-
-### `include/xrpl/protocol/detail/transactions.macro`
-
-Transaction types have a unique **transaction type number**. New feature transactions go **at the bottom** of the active transaction list (before the system transactions starting at 100+).
-
-**Resolution strategy:**
-1. Keep all of `develop`'s transactions.
-2. Add your feature's transactions at the bottom with the next available number.
-3. Use the new 7-argument `TRANSACTION` macro format:
-
-```cpp
-/** Description of the transaction */
-#if TRANSACTION_INCLUDE
-#   include <xrpl/tx/transactors/MyTransactor.h>
-#endif
-TRANSACTION(ttMY_TX, <next_number>, MyTx,
-    Delegation::delegable,
-    featureMyFeature,
-    noPriv, ({
-    {sfSomeField, soeREQUIRED},
-}))
-```
-
-To find the next available transaction number:
-```bash
-grep "^TRANSACTION(" include/xrpl/protocol/detail/transactions.macro | sed 's/.*,\s*\([0-9]*\),.*/\1/' | sort -n
-```
-
-Note: Transaction numbers 100+ are reserved for system transactions (amendments, fees, UNL).
-
-### `include/xrpl/protocol/detail/ledger_entries.macro`
-
-Ledger entry types have a unique **ledger type number** (hex). New entries go **at the bottom** of the active list.
-
-**Resolution strategy:**
-1. Keep all of `develop`'s entries.
-2. Add your feature's entries at the bottom with the next available hex number.
-3. Check for collisions:
-
-```bash
-grep "^LEDGER_ENTRY(" include/xrpl/protocol/detail/ledger_entries.macro | grep -o '0x[0-9a-fA-F]*'  | sort
-```
-
-### `src/libxrpl/protocol/Indexes.cpp`
-
-The `LedgerNameSpace` enum assigns a unique single character to each ledger entry type for index hashing.
-
-**Resolution strategy:**
-1. Keep both sides' entries.
-2. Check for character collisions. Each entry needs a unique char.
-3. Find used characters:
-
-```bash
-grep -E "^\s+[A-Z_]+ = " src/libxrpl/protocol/Indexes.cpp | sed "s/.*= '//;s/'.*//" | sort | tr -d '\n'
-```
-
-Also check the deprecated chars (reserved, cannot reuse):
-```bash
-grep "deprecated" src/libxrpl/protocol/Indexes.cpp | sed "s/.*= '//;s/'.*//"
-```
-
-### `src/libxrpl/protocol/InnerObjectFormats.cpp`
-
-Inner object formats define the fields allowed inside array elements (e.g., `sfSigners`, `sfPasskeys`).
-
-**Resolution:** Keep both sides' `add(...)` calls. No numbering conflicts here — just ensure no duplicate registrations.
-
-### `src/libxrpl/protocol/STTx.cpp`
-
-The `singleSignHelper` function was refactored in `develop`:
-- Parameter name: `sigObject` (not `signer`)
-- Signature retrieval: `sigObject.getFieldVL(sfTxnSignature)` (not `getSignature(signer)`)
-- No `fullyCanonical` parameter — canonical sig checking was simplified
-
-**Resolution:** Take `develop`'s function signatures and patterns. Adapt any feature-specific logic to match.
-
-### `src/libxrpl/protocol/SecretKey.cpp`
-
-**Resolution:** Use `namespace xrpl`. Keep any additional `#include` directives your feature needs (e.g., OpenSSL headers for new key types).
-
-### `src/libxrpl/tx/Transactor.cpp`
-
-The `checkSign` / `checkSingleSign` / `checkMultiSign` functions were refactored in `develop`:
-- `checkSingleSign` no longer takes a `Rules` parameter
-- `checkSign` has a new overload taking `PreclaimContext`
-- `checkBatchSign` uses the simplified `checkSingleSign` call
-
-**Resolution:** Take `develop`'s function signatures. Add any new authentication checks (e.g., passkey verification) into `checkSingleSign` before the final `return tefBAD_AUTH`, using `view.read(...)` to check ledger state.
-
-### `src/libxrpl/tx/applySteps.cpp`
-
-**Resolution:** Always take `develop`'s macro-based include approach:
-```cpp
-#include <xrpl/tx/applySteps.h>
-#pragma push_macro("TRANSACTION")
-#undef TRANSACTION
-
-#define TRANSACTION(...)
-#define TRANSACTION_INCLUDE 1
-
-#include <xrpl/protocol/detail/transactions.macro>
-
-#undef TRANSACTION
-#pragma pop_macro("TRANSACTION")
-```
-
-Never use the old explicit `#include <xrpld/app/tx/detail/*.h>` list.
-
-### `src/test/jtx/impl/utility.cpp`
-
-The `sign` function was refactored in `develop`:
-- Takes `sigObject` parameter: `sign(Json::Value& jv, Account const& account, Json::Value& sigObject)`
-- Has an overload: `sign(Json::Value& jv, Account const& account)` that calls `sign(jv, account, jv)`
-- Uses `xrpl::sign(...)` not `ripple::sign(...)`
-
-**Resolution:** Take `develop`'s function signatures. Adapt feature-specific signing logic to the new pattern.
-
-## Conflict Resolution Checklist
-
-1. List all conflicted files: `git diff --name-only --diff-filter=U`
-2. Check which have actual conflict markers vs just unmerged: `grep -l "<<<<<<< HEAD" <file>`
-3. For files without markers: stage them or `git rm` if they were moved
-4. For each file with markers:
-   - Take `develop`'s structural changes (namespace, function signatures, macro formats)
-   - Preserve your feature's additions (new fields, entries, transactions, logic)
-   - Resolve any numbering collisions by incrementing to the next available number
-5. Stage resolved files: `git add <file>`
-6. Verify no remaining markers: `grep -r "<<<<<<< " --include="*.cpp" --include="*.h" --include="*.macro"`
-7. Verify no remaining unmerged: `git diff --name-only --diff-filter=U`

-# App Module Best Practices
-
-## Description
-Use when working with the main application layer in `src/xrpld/app/`. Covers the Application singleton, ledger management, consensus adapters, services, and runtime coordination.
-
-## Responsibility
-Contains the main application logic and runtime coordination for the rippled server. The Application singleton provides access to all services. Sub-modules handle ledger management, consensus, fee voting, amendments, path finding, and transaction queuing.
-
-## Key Patterns
-
-### Application Singleton
-```cpp
-// Application is the master interface - access all services through it
-class Application {
-    virtual Config& config() = 0;
-    virtual Logs& logs() = 0;
-    virtual JobQueue& getJobQueue() = 0;
-    virtual LedgerMaster& getLedgerMaster() = 0;
-    virtual NetworkOPs& getOPs() = 0;
-    virtual NodeStore::Database& getNodeStore() = 0;
-    // ... many more service accessors
-};
-// Implemented by ApplicationImp (hidden in .cpp)
-```
-
-### ServiceRegistry Pattern
-```cpp
-// Services are injected via ServiceRegistry from libxrpl
-// Application provides centralized access to all registered services
-```
-
-### Master Mutex
-```cpp
-// Recursive mutex protects shared state:
-using MutexType = std::recursive_mutex;
-// Protects: open ledger, server state, consensus engine
-// Use std::lock_guard<Application::MutexType> for access
-```
-
-### Module Interface Pattern
-```cpp
-// Public interface: Module.h (abstract)
-// Implementation: ModuleImp.h/cpp (hidden)
-// Factory: make_Module() returns unique_ptr
-```
-
-## Common Pitfalls
-- Never access Application services before setup() completes
-- Always acquire master mutex when modifying open ledger or consensus state
-- Use `std::recursive_mutex` (not plain mutex) - multiple services may lock re-entrantly
-- Never create a second Application instance

-# App Consensus Module Best Practices
-
-## Description
-Use when working with RCL consensus adapters in `src/xrpld/app/consensus/`. Bridges the generic consensus algorithm to rippled-specific types.
-
-## Responsibility
-Adapts the generic consensus algorithm (in `xrpld/consensus/`) to work with rippled application types. Provides concrete type adapters for transactions, transaction sets, and ledgers.
-
-## Key Patterns
-
-### RCL Adapters
-```cpp
-// RCLCxTx     - Adapts SHAMapItem as a consensus transaction
-// RCLCxTxSet  - Adapts SHAMap as a consensus transaction set
-// RCLCxLedger - Adapts Ledger as a consensus ledger
-// RCLConsensus - Glues generic consensus to rippled Application
-```
-
-### Adapter Pattern
-```cpp
-// Generic consensus works with abstract types via CRTP
-// RCL adapters provide concrete implementations
-class RCLConsensus : public Consensus<RCLConsensus> {
-    // Implements required methods using rippled types
-    // e.g., acquireLedger(), proposeTx(), relay()
-};
-```
-
-### Validation Handling
-```cpp
-// RCLValidations tracks validation messages from the network
-// Maps to the generic Validations<> template
-// Handles trusted vs untrusted validators
-```
-
-## Common Pitfalls
-- Adapter methods must match the CRTP interface exactly - compiler errors are cryptic
-- Never import generic consensus types into adapter code - always go through the adapter
-- RCLConsensus holds references to Application services - ensure Application outlives it
-
-## Key Files

-# App Ledger Module Best Practices
-
-## Description
-Use when working with ledger management in `src/xrpld/app/ledger/`. Covers ledger storage, retrieval, history, and the Ledger class itself.
-
-## Responsibility
-Manages the lifecycle of ledger objects: creation, storage, retrieval, history tracking, inbound acquisition from network, and order book caching. The Ledger class is the central data structure.
-
-## Key Patterns
-
-### Ledger Class
-```cpp
-// Ledger is composed of two SHAMaps:
-// 1. State Map  - Account roots, order books, ledger entries (STLedgerEntry)
-// 2. Transaction Map - Transactions and metadata for that ledger
-
-class Ledger final : public std::enable_shared_from_this<Ledger>,
-                     public CountedObject<Ledger> {
-    // Can be mutable (sole ownership) or immutable (shared, read-only)
-    // Genesis ledger has special constructor
-};
-```
-
-### Mutable vs Immutable
-```cpp
-// Mutable: Only one owner, can be modified
-// Immutable: Shared via shared_ptr, read-only
-// Transition: mutable -> immutable when accepted
-// Never modify an immutable ledger
-```
-
-### LedgerMaster
-```cpp
-// Manages the chain of validated ledgers
-// Tracks: current, validated, closed ledgers
-// Handles ledger transitions during consensus
-```
-
-### Inbound Ledger Acquisition
-```cpp
-// InboundLedgers manages acquiring missing ledgers from peers
-// InboundTransactions handles transaction set acquisition
-// Both use async fetch with timeout and retry
-```
-
-### Iterator Adapters
-```cpp
-// sles_iter_impl - Iterate over SLE (state entries)
-// txs_iter_impl  - Iterate over transactions
-// Efficient iteration without copying
-```
-
-## Common Pitfalls
-- Never modify an immutable ledger - check mutability first
-- Ledger must be shared via shared_ptr (enable_shared_from_this)
-- Genesis ledger construction is special - don't use for normal ledgers
-- LedgerMaster state transitions must be atomic with consensus
-- CountedObject tracking helps detect leaks - don't disable it

-
-## Responsibility
-Internal implementation details for the app/ledger module. Contains private helpers for ledger state management, iteration, and storage operations.
-
-## Key Patterns
-
-### Detail Namespace Convention
-- Code in `detail/` is internal to the `app/ledger` module
-- Never include detail headers from outside `app/ledger`
-- If you need functionality, use the public `app/ledger/` headers instead
-
-## Common Pitfalls
-- Detail implementations may change without API compatibility
-- Never expose detail types in public interfaces

-# App Main Module Best Practices
-
-## Description
-Use when working with application initialization and lifecycle in `src/xrpld/app/main/`. Covers Application startup, shutdown, and core services.
-
-## Responsibility
-Application initialization, lifecycle management, and core service wiring. Contains the Application interface and its implementation, gRPC server, load management, node identity, and the node store scheduler.
-
-## Key Patterns
-
-### Application Lifecycle
-```cpp
-// 1. Construct Application (parse config, create services)
-// 2. setup() - Initialize all services, open databases
-// 3. run() - Main event loop
-// 4. signalStop() - Graceful shutdown
-// 5. Destructor - Clean up resources
-```
-
-### Node Identity
-```cpp
-// NodeIdentity manages the node's public/private key pair
-// Used for peer handshake, session signatures, and cluster membership
-// Keys persisted in wallet_db
-```
-
-### Load Manager
-```cpp
-// Tracks server load across all subsystems
-// Triggers load-based fee escalation
-// Monitors job queue depth and execution time
-```
-
-### gRPC Server
-```cpp
-// Optional gRPC server alongside JSON-RPC
-// Uses proto definitions from include/xrpl/proto/
-// Separate handler set from JSON-RPC
-```
-
-## Common Pitfalls
-- setup() must complete before any service is used
-- signalStop() should be called for graceful shutdown - avoid hard kills
-- Node identity keys must never be logged or exposed
-- Load manager affects fee escalation - test under load

-# App Misc Module Best Practices
-
-## Description
-Use when working with application services in `src/xrpld/app/misc/`. Covers fee voting, amendments, SHAMapStore, transaction queue, validator management, and NetworkOPs.
-
-## Responsibility
-Collection of application-level services: fee voting system, amendment mechanism, online deletion (SHAMapStore), transaction queue (TxQ), validator key/list management, and NetworkOPs (the central operations coordinator).
-
-## Key Patterns
-
-### Fee Voting
-```cpp
-// Validators vote on fee schedules every 256 ledgers ("voting ledgers")
-// Pseudo-transactions injected to set fees
-// Majority vote determines new fee schedule
-// FeeVote.h - voting logic
-// FeeEscalation.md - escalation documentation
-```
-
-### Amendment Mechanism
-```cpp
-// Network-wide ledger rule changes
-// Requires 80% validator approval sustained for 2 weeks
-// Tracked as pseudo-transactions in each ledger
-// AmendmentTableImpl.h manages tracking and state
-```
-
-### SHAMapStore (Online Delete)
-```cpp
-// Prunes old ledger history automatically
-// Uses rotation between two databases
-// Configurable deletion intervals
-// Must not delete data needed for active operations
-```
-
-### Transaction Queue (TxQ)
-```cpp
-// Queues transactions when ledger is full
-// Priority based on fee level
-// Handles fee escalation under load
-// TxQ.h - queue implementation
-```
-
-### Validator Management
-```cpp
-// ValidatorKeys.h - Node's own validator keys
-// ValidatorList.h - Trusted validator list (UNL)
-// ValidatorSite.h - Sites serving validator lists
-// Keys loaded from config, lists fetched from URLs
-```
-
-### NetworkOPs
-```cpp
-// Central operations coordinator - the "god object"
-// Coordinates: consensus, ledger acceptance, transaction submission
-// NetworkOPs.cpp is one of the largest files in the codebase
-// Access via app.getOPs()
-```
-
-## Common Pitfalls
-- Fee voting only happens on voting ledgers (every 256) - don't trigger manually
-- Amendments require 2-week sustained 80% approval - no fast path
-- SHAMapStore deletion must respect the advisory_delete safety window
-- TxQ priority depends on current fee escalation level
-- NetworkOPs is massive - changes here affect many systems

-# App Paths Module Best Practices
-
-## Description
-Use when working with payment path finding in `src/xrpld/app/paths/`. Covers the path finding algorithm, trust line caching, and AMM liquidity integration.
-
-## Responsibility
-Implements the XRP Ledger payment path finding algorithm at the application level. Manages path requests, trust line caching, and integration with Automated Market Maker liquidity.
-
-## Key Patterns
-
-### Path Finding
-```cpp
-// Pathfinder: Algorithm that finds payment paths between accounts
-// Considers: trust lines, order books, AMM pools
-// Returns: Set of paths ranked by cost/quality
-```
-
-### Path Request Management
-```cpp
-// PathRequest  - Individual path find request
-// PathRequests - Manages collection of active requests
-// Requests can be one-shot or subscribed (streaming updates)
-```
-
-### Trust Line Caching
-```cpp
-// RippleLineCache caches trust line data
-// Avoids repeated ledger lookups during path finding
-// Cache is invalidated on ledger close
-// TrustLine.h provides the trust line representation
-```
-
-### AMM Integration
-```cpp
-// AMMLiquidity.h - Integrates AMM pools into path finding
-// AMMOffer.h - Represents AMM as a synthetic offer
-// AMM pools are treated as a special offer type in the path finder
-```
-
-## Common Pitfalls
-- Path finding is computationally expensive - respect search depth limits
-- Trust line cache must be invalidated on ledger close
-- AMM liquidity changes with pool state - don't cache AMM offers across ledgers
-- Path subscriptions can be memory-intensive with many clients

-## Description
-Use when working with application-level transaction handling in `src/xrpld/app/tx/`. Covers transaction submission, validation, and application-layer processing.
-
-## Responsibility
-Application-level transaction handling that bridges the protocol-layer transaction processing (libxrpl/tx) with the running server. Handles transaction submission, validation, and integration with the consensus process.
-
-## Key Patterns
-
-### Relationship to libxrpl/tx
-```cpp
-// libxrpl/tx: Protocol-level transaction processing (Transactor, preflight, preclaim, doApply)
-// xrpld/app/tx: Application-level orchestration (submission, queuing, consensus integration)
-// This module calls into libxrpl/tx for actual transaction execution
-```
-
-### Transaction Submission Flow

-// 1. Client submits transaction via RPC
-// 2. app/tx validates and queues transaction
-// 3. Transaction enters TxQ (app/misc/TxQ)
-// 4. Consensus selects transactions for next ledger
-// 5. libxrpl/tx executes selected transactions
-```
-
-## Common Pitfalls

-# Consensus Module Best Practices
-
-## Description
-Use when working with the generic consensus algorithm in `src/xrpld/consensus/`. This is the application-independent consensus implementation.
-
-## Responsibility
-Implements the generic consensus algorithm separate from application-specific types. Uses CRTP (Curiously Recurring Template Pattern) to allow the application layer to plug in concrete types without virtual dispatch overhead.
-
-## Key Patterns
-
-### CRTP Design
-```cpp
-// Generic consensus uses CRTP - derived class provides concrete types
-template <class Derived>
-class Consensus {
-    // Calls static_cast<Derived*>(this)->method() for app-specific behavior
-    // No virtual dispatch overhead
-};
-
-// Application adapter:
-class RCLConsensus : public Consensus<RCLConsensus> {
-    // Provides concrete types: RCLCxTx, RCLCxTxSet, RCLCxLedger
-};
-```
-
-### Consensus Phases
-```cpp
-// Open -> Establish -> Accept
-// Open: Collecting transactions
-// Establish: Proposing and voting on transaction set
-// Accept: Applying agreed-upon transaction set to ledger
-```
-
-### Consensus Parameters (ConsensusParms.h)
-```cpp
-// Timing parameters for consensus rounds
-// These are tuned for network behavior - don't change without careful analysis
-```
-
-### Disputed Transactions
-```cpp
-// DisputedTx tracks transactions where validators disagree
-// Votes are collected and transaction is included/excluded based on threshold
-```
-
-## Common Pitfalls
-- Never modify consensus parameters without understanding network-wide impact
-- CRTP means compilation errors from type mismatches appear in template instantiation - read errors carefully
-- The generic consensus module should NEVER depend on application-specific types (Ledger, STTx, etc.)
-- Always test consensus changes with multi-node simulation

-# Core Module Best Practices
-
-## Description
-Use when working with core configuration and system services in `src/xrpld/core/`. Covers Config, time keeping, and network identity.
-
-## Responsibility
-System-level configuration and core services. The Config class extends BasicConfig from libxrpl with rippled-specific settings. Provides time keeping and network ID management.
-
-## Key Patterns
-
-### Config Class
-```cpp
-// Config extends BasicConfig from libxrpl
-class Config : public BasicConfig {
-    // SizedItem enum for memory-dependent configuration
-    enum SizedItem { siSweepInterval, siNodeCacheSize, ... };
-

-        XRPAmount owner_reserve;
-    };
-
-    // Access sections by name
-    auto const& section = config["server"];
-};
-```
-
-### Configuration Sections
-```cpp
-// Section names defined in ConfigSections.h
-static constexpr char const* SECTION_NODE_DB = "node_db";
-static constexpr char const* SECTION_VALIDATORS = "validators";
-// Always use constants, never string literals
-```
-
-### Gradual Refactoring
-```cpp
-// Legacy config uses mixed patterns - refactoring is ongoing
-// New code should follow the Section-based approach
-// Deprecated patterns are documented with TODO comments
-```
-
-## Common Pitfalls
-- Always use `ConfigSections.h` constants for section names

-# Overlay Module Best Practices
-
-## Description
-Use when working with P2P networking in `src/xrpld/overlay/`. Covers peer connections, protocol negotiation, message relay, and clustering.
-
-## Responsibility
-Manages peer-to-peer connections and the overlay network protocol. Handles HTTP/1.1 upgrade handshake, session signatures (MITM prevention), Protocol Buffer message serialization, message compression, and cluster node management.
-
-## Key Patterns
-
-### HTTP/1.1 Upgrade Handshake
-```cpp
-// Connection starts as HTTP, upgrades to ripple protocol
-// Custom headers:
-// Connect-As, Public-Key, Session-Signature
-// Network-ID, Network-Time
-// Closed-Ledger, Previous-Ledger
-// Remote-IP, Local-IP, Crawl
-```
-
-### Session Signature (MITM Prevention)
-```cpp
-// Binds SSL/TLS session to node identities
-// Each peer signs the shared SSL session data
-// Prevents man-in-the-middle attacks at the protocol level
-```
-
-### Message Serialization
-```cpp
-// Google Protocol Buffers for all p2p messages
-// Messages are compressed before transmission
-// Compression.h handles LZ4/no-compression selection
-```
-
-### Peer Management
-```cpp
-// Overlay manages the set of connected peers
-class Overlay {
-    virtual Peer::ptr findPeerByShortID(Peer::id_t) = 0;
-    virtual void send(std::shared_ptr<Message> const&) = 0;  // Broadcast
-    virtual void relay(Message const&, uint256 const& suppression) = 0;
-};
-```
-
-### Clustering
-```cpp
-// Multiple rippled nodes can form a cluster
-// Cluster nodes: share load, distribute crypto operations
-// Cluster membership verified via node public keys
-```
-
-### Reduce Relay
-```cpp
-// ReduceRelayCommon.h - Minimize redundant message relay
-// Uses HashRouter for message deduplication
-// Peers track which messages they've already seen
-```
-
-## Common Pitfalls
-- Always validate session signatures during handshake - never skip
-- Never send uncompressed messages to peers that advertise compression support
-- Cluster keys must be pre-configured - no dynamic cluster joining
-- Message suppression via HashRouter is critical for network health - never bypass
-- Protocol Buffer messages must match the expected schema version

-# PeerFinder Module Best Practices
-
-## Description
-Use when working with network discovery in `src/xrpld/peerfinder/`. Covers peer bootstrap, cache management, and connection slot strategy.
-
-## Responsibility
-Bootstraps into the XRP Ledger network and discovers peers. Manages bootcache (persistent addresses ranked by success), livecache (ephemeral recently-seen peers), and connection slot allocation.
-
-## Key Patterns
-
-### Three-Stage Connection Strategy
-```cpp
-// Stage 1: Connect to fixed peers (configured addresses)
-// Stage 2: Try Livecache addresses (recently seen, with open slots)
-// Stage 3: Fall back to Bootcache (persistent, ranked by valence)
-```
-
-### Bootcache (Persistent)
-```cpp
-// Persistent store of peer addresses ranked by "valence" (connection success)
-// Higher valence = more reliable peer
-// Persisted across restarts
-// Used as fallback when livecache is empty
-```
-
-### Livecache (Ephemeral)
-```cpp
-// Recently seen peers with available connection slots
-// Uses hop counts for distance estimation
-// Random distribution for load balancing
-// Not persisted - rebuilt on restart via gossip
-```
-
-### Slot Management
-```cpp
-// Slot states: accept, connect, connected, active, closing
-// Slot properties: Inbound/Outbound, Fixed, Cluster
-// Slots track connection lifecycle from handshake to disconnect
-```
-
-### Callback Pattern
-```cpp
-// Abstract interface for socket operations
-// PeerFinder doesn't directly manage sockets
-// Delegates I/O to the overlay layer via callbacks
-```
-
-## Common Pitfalls
-- Fixed peers should always be tried first (Stage 1) - they are trusted
-- Bootcache valence can decay over time - implement proper aging
-- Livecache entries expire quickly - don't rely on stale data
-- Slot limits prevent connection exhaustion - never bypass them
-- Always check README.md for algorithm details before modifying

-## Description
-Use when working with RPC request handling in `src/xrpld/rpc/`. Covers command dispatch, handler implementation, coroutine suspension, and the gRPC interface.
-
-## Responsibility
-HTTP/JSON and gRPC RPC interface to rippled. Dispatches requests to 40+ command handlers, manages request context, supports coroutine-based suspension for async operations, and handles user roles/permissions.
-
-## Key Patterns
-
-### RPC Handler Pattern
-```cpp
-// Each handler is a function taking context, returning Json::Value
-Json::Value doMyCommand(RPC::JsonContext& context) {
-    // Validate parameters
-    if (!context.params.isMember("field"))

-
-    // Build response
-    Json::Value result(Json::objectValue);
-    result["status"] = "success";
-    return result;
-}
-```
-
-### Coroutine Suspension
-```cpp
-// RPC handlers can suspend for async operations
-// Key types:
-// Callback     - 0-argument function
-// Continuation - Takes callback, promises to call it later
-// Suspend      - Function from coroutine that takes continuation
-// Coroutine    - Function given suspend to enable suspension
-
-// This allows handlers to yield without blocking threads
-```
-
-### Request Context
-```cpp
-struct JsonContext {
-    Application& app;
-    Resource::Charge& loadType;
-    Json::Value params;
-    beast::Journal j;
-    Role role;  // User, Admin, Identified, etc.
-};

-### Role-Based Access
-```cpp
-enum class Role { GUEST, USER, ADMIN, IDENTIFIED, PROXY, FORBID };
-// Handlers specify minimum required role
-// Admin handlers only accessible from admin IP ranges
-```
-
-### Error Handling
-```cpp
-// Standard error helpers:
-RPC::missing_field_error("field_name");
-RPC::invalid_field_error("field_name");
-RPC::make_error(rpcINVALID_PARAMS, "description");
-// Errors injected into JSON response
-```
-
-### gRPC Handlers
-```cpp
-// Separate handler set for gRPC interface
-// Defined in GRPCHandlers.h
-// Use Protocol Buffer request/response types
-// Convert to/from native types at boundary
-```
-
-## Common Pitfalls
-- Always validate parameters before accessing them
-- Check user Role before executing privileged operations
-- Use coroutine suspension for any operation that might block
-- Never return internal data structures directly - always convert to JSON
-- Handler functions are in `handlers/` directory - one file per command or group
-- gRPC handlers must convert proto types to native types at the boundary
-
-## Key Files
-- `src/xrpld/rpc/RPCHandler.h` - Command dispatcher
-- `src/xrpld/rpc/Context.h` - RPC context/state
-- `src/xrpld/rpc/Status.h` - RPC status codes
-- `src/xrpld/rpc/Role.h` - User role/permissions

-# RPC Detail Module Best Practices
-
-## Description
-Use when working with RPC implementation details in `src/xrpld/rpc/detail/`. Internal helpers for the RPC module.
-
-## Responsibility
-Internal implementation details for RPC handling, including request parsing, response formatting, coroutine machinery, and middleware.
-
-## Common Pitfalls
-- Coroutine state must be carefully managed to prevent leaks
-- Never include detail headers from outside rpc/

-# RPC Handlers Module Best Practices
-
-## Description
-Use when adding or modifying RPC command handlers in `src/xrpld/rpc/handlers/`. Contains 40+ individual RPC command implementations.
-
-## Responsibility
-Individual RPC command handler implementations. Each file implements one or more related RPC commands following the standard handler pattern.
-
-## Key Patterns
-
-### Handler Function Signature
-```cpp
-// Standard handler pattern
-Json::Value doMyCommand(RPC::JsonContext& context) {
-    // 1. Validate parameters
-    if (!context.params.isMember("required_field"))
-        return RPC::missing_field_error("required_field");
-
-    // 2. Check permissions
-    // (Role already verified by dispatcher based on handler metadata)
-
-    // 3. Access application services
-    auto& app = context.app;
-    auto& ledger = context.ledgerMaster.getValidatedLedger();
-
-    // 4. Execute logic
-    // ...
-
-    // 5. Build and return response
-    Json::Value result(Json::objectValue);
-    result["status"] = "success";
-    return result;
-}
-```
-
-### Parameter Validation
-```cpp
-// Use standard error helpers
-RPC::missing_field_error("field_name");    // Required field missing
-RPC::invalid_field_error("field_name");    // Field has wrong type/value
-RPC::make_error(rpcINVALID_PARAMS, "description"); // Generic error
-```
-
-### Adding a New Handler
-1. Create a new .cpp file in `handlers/`
-2. Implement the handler function following the pattern above
-3. Register the command in the handler dispatch table
-4. Document the command parameters and response format
-
-### Common Handler Files
-```
-AccountInfo.cpp     - account_info command
-AccountLines.cpp    - account_lines (trust lines)
-AccountOffers.cpp   - account_offers
-Submit.cpp          - submit (transaction submission)
-Subscribe.cpp       - subscribe (event streaming)
-LedgerData.cpp      - ledger_data
-ServerInfo.cpp      - server_info
-Fee1.cpp            - fee command
-Tx.cpp              - tx (transaction lookup)
-BookOffers.cpp      - book_offers (order book)
-```
-
-## Common Pitfalls
-- Always validate ALL parameters before using them
-- Never return internal data structures - convert to JSON at the boundary
-- Respect Role-based access control - admin handlers must check role
-- Handlers should be stateless - all state comes from context
-- Use coroutine suspension for any blocking operation (DB queries, network)
-- Error responses must follow the standard error format
-
-## Key Files
-- `src/xrpld/rpc/handlers/` - All handler implementations
-- `src/xrpld/rpc/RPCHandler.h` - Dispatch table and registration

-# SHAMap (xrpld) Module Best Practices
-
-## Description
-Use when working with application-level SHAMap operations in `src/xrpld/shamap/`. Covers NodeFamily and application integration with the Merkle tree.
-
-## Responsibility
-Application-level integration of the SHAMap (Merkle radix tree) with the rippled server. Provides NodeFamily for managing tree node relationships and connecting the generic SHAMap to the node store.
-
-## Key Patterns
-
-### NodeFamily
-```cpp
-// NodeFamily connects SHAMap to the persistent NodeStore
-// Provides: database access, tree node creation, hash verification
-// Each SHAMap references a Family for storage operations
-```
-
-### Relationship to libxrpl/shamap
-```cpp
-// libxrpl/shamap: Generic Merkle tree implementation
-// xrpld/shamap: Application-specific integration (NodeFamily, storage)
-// The generic tree doesn't know about databases - NodeFamily bridges the gap
-```
-
-## Common Pitfalls
-- Always use NodeFamily to create SHAMap instances connected to storage
-- The libxrpl SHAMap is the implementation - this module is the glue layer
-- Don't duplicate SHAMap logic here - extend via NodeFamily only
-
-## Key Files
-- `src/xrpld/shamap/NodeFamily.h` - Family relationship management
-- `src/xrpld/shamap/NodeFamily.cpp` - Implementation

 inconsistent, so the current state of the code doesn't necessarily
 reflect these rules. Whenever possible, developers should refactor any
 levelization violations they find (by moving files or individual
 classes). At the very least, don't make things worse.

-## Renaming ripple(d) to xrpl(d)
-
-In the initial phases of development of the XRPL, the open source codebase was
-called "rippled" and it remains with that name even today. Today, over 1000
-nodes run the application, and code contributions have been submitted by
-developers located around the world. The XRPL community is larger than ever.
-In light of the decentralized and diversified nature of XRPL, we will rename any
-references to `ripple` and `rippled` to `xrpl` and `xrpld`, when appropriate.
-
-See [here](https://xls.xrpl.org/xls/XLS-0095-rename-rippled-to-xrpld.html) for
-more information.
-
-### Scripts
-
-To facilitate this transition, there will be multiple scripts that developers
-can run on their own PRs and forks to minimize conflicts. Each script should be
-run from the repository root.
-
-1. `.github/scripts/rename/definitions.sh`: This script will rename all
-   definitions, such as include guards, from `RIPPLE_XXX` and `RIPPLED_XXX` to
-   `XRPL_XXX`.
-2. `.github/scripts/rename/copyright.sh`: This script will remove superfluous
-   copyright notices.
-3. `.github/scripts/rename/cmake.sh`: This script will rename all CMake files
-   from `RippleXXX.cmake` or `RippledXXX.cmake` to `XrplXXX.cmake`, and any
-   references to `ripple` and `rippled` (with or without capital letters) to
-   `xrpl` and `xrpld`, respectively. The name of the binary will remain as-is,
-   and will only be renamed to `xrpld` by a later script.
-4. `.github/scripts/rename/binary.sh`: This script will rename the binary from
-   `rippled` to `xrpld`, and reverses the symlink so that `rippled` points to
-   the `xrpld` binary.
-5. `.github/scripts/rename/namespace.sh`: This script will rename the C++
-   namespaces from `ripple` to `xrpl`.
-6. `.github/scripts/rename/config.sh`: This script will rename the config from
-   `rippled.cfg` to `xrpld.cfg`, and updating the code accordingly. The old
-   filename will still be accepted.
-
-You can run all these scripts from the repository root as follows:
-
-```shell
-./.github/scripts/rename/definitions.sh .
-./.github/scripts/rename/copyright.sh .
-./.github/scripts/rename/cmake.sh .
-./.github/scripts/rename/binary.sh .
