-## Clang-tidy
-
-All code must pass `clang-tidy` checks according to the settings in [`.clang-tidy`](./.clang-tidy).
-
-There is a Continuous Integration job that runs clang-tidy on pull requests. The CI will check:
-
-- All changed C++ files (`.cpp`, `.h`, `.ipp`) when only code files are modified
-- **All files in the repository** when the `.clang-tidy` configuration file is changed
-
-This ensures that configuration changes don't introduce new warnings across the codebase.
-
-### Running clang-tidy locally
-
-Before running clang-tidy, you must build the project to generate required files (particularly protobuf headers). Refer to [`BUILD.md`](./BUILD.md) for build instructions.
-
-Then run clang-tidy on your local changes:
-
-```
-run-clang-tidy -p build src tests
-```
-
-This will check all source files in the `src` and `tests` directories using the compile commands from your `build` directory.
-

- *       allocators.

- * @note Only memory served from glibc's sbrk/arena heaps is eligible for trim.
- *       Large allocations satisfied via mmap are usually returned on free

-assert(enforce)
-
-There are several asserts (or XRPL_ASSERTs) in invariant check files that check
-a variable named `enforce` when an invariant fails. At first glance, those
-asserts may look incorrect, but they are not.
-
-Those asserts take advantage of two facts:
-1. `asserts` are not (normally) executed in release builds.
-2. Invariants should *never* fail, except in tests that specifically modify
-   the open ledger to break them.
-
-This makes `assert(enforce)` sort of a second-layer of invariant enforcement
-aimed at _developers_. It's designed to fire if a developer writes code that
-violates an invariant, and runs it in unit tests or a develop build that _does
-not have the relevant amendments enabled_. It's intentionally a pain in the neck
-so that bad code gets caught and fixed as early as possible.

- * @brief Invariants: Vault object and MPTokenIssuance for vault shares
- *
- * - vault deleted and vault created is empty
- * - vault created must be linked to pseudo-account for shares and assets
- * - vault must have MPTokenIssuance for shares
- * - vault without shares outstanding must have no shares
- * - loss unrealized does not exceed the difference between assets total and
- *   assets available
- * - assets available do not exceed assets total
- * - vault deposit increases assets and share issuance, and adds to:
- *   total assets, assets available, shares outstanding
- * - vault withdrawal and clawback reduce assets and share issuance, and
- *   subtracts from: total assets, assets available, shares outstanding
- * - vault set must not alter the vault assets or shares balance
- * - no vault transaction can change loss unrealized (it's updated by loan
- *   transactions)
- *

-# WASM Module for Programmable Escrows
-
-This module provides WebAssembly (WASM) execution capabilities for programmable
-escrows on the XRP Ledger. When an escrow is finished, the WASM code runs to
-determine whether the escrow conditions are met, enabling custom programmable
-logic for escrow release conditions.
-
-For the full specification, see
-[XLS-0102: WASM VM](https://xls.xrpl.org/xls/XLS-0102-wasm-vm.html).
-
-## Architecture
-
-The module follows a layered architecture:
-
-```
-┌─────────────────────────────────────────────────────────────┐
-│                 WasmEngine (WasmVM.h)                       │

-└─────────────────────────────────────────────────────────────┘
-```
-
-### Key Components
-
-- **`WasmVM.h` / `detail/WasmVM.cpp`** - High-level facade providing:
-  - `WasmEngine` singleton that wraps the underlying WASM interpreter
-  - `runEscrowWasm()` - Execute WASM code for escrow finish
-  - `preflightEscrowWasm()` - Validate WASM code during preflight
-  - `createWasmImport()` - Register all host functions
-
-- **`WasmiVM.h` / `detail/WasmiVM.cpp`** - Low-level integration with the
-  [wasmi](https://github.com/wasmi-labs/wasmi) WebAssembly interpreter:
-  - `WasmiEngine` - Manages WASM modules, instances, and execution
-  - Memory management and gas metering
-  - Function invocation and result handling
-
-- **`HostFunc.h`** - Abstract `HostFunctions` base class defining the interface
-  for all callable host functions. Each method returns
-  `Expected<T, HostFunctionError>`.
-
-- **`HostFuncImpl.h` / `detail/HostFuncImpl*.cpp`** - Concrete
-  `WasmHostFunctionsImpl` class that implements host functions with access to
-  `ApplyContext` for ledger state queries. Implementation split across files:
-  - `HostFuncImpl.cpp` - Core utilities (updateData, checkSignature, etc.)
-  - `HostFuncImplFloat.cpp` - Float/number arithmetic operations
-  - `HostFuncImplGetter.cpp` - Field access (transaction, ledger objects)
-  - `HostFuncImplKeylet.cpp` - Keylet construction functions
-  - `HostFuncImplLedgerHeader.cpp` - Ledger header info access
-  - `HostFuncImplNFT.cpp` - NFT-related queries
-  - `HostFuncImplTrace.cpp` - Debugging/tracing functions
-
-- **`HostFuncWrapper.h` / `detail/HostFuncWrapper.cpp`** - C-style wrapper
-  functions that bridge WASM calls to C++ `HostFunctions` methods. Each host
-  function has:
-  - A `_proto` type alias defining the function signature
-  - A `_wrap` function that extracts parameters and calls the implementation
-
-- **`ParamsHelper.h`** - Utilities for WASM parameter handling:
-  - `WASM_IMPORT_FUNC` / `WASM_IMPORT_FUNC2` macros for registration
-  - `wasmParams()` helper for building parameter vectors
-  - Type conversion between WASM and C++ types
-
-## Host Functions
-
-Host functions allow WASM code to interact with the XRP Ledger. They are
-organized into categories:
-
-- **Ledger Information** - Access ledger sequence, timestamps, hashes, fees
-- **Transaction & Ledger Object Access** - Read fields from the transaction
-  and ledger objects (including the current escrow object)
-- **Keylet Construction** - Build keylets to look up various ledger object types
-- **Cryptography** - Signature verification and hashing
-- **Float Arithmetic** - Mathematical operations for amount calculations
-- **NFT Operations** - Query NFT properties
-- **Tracing/Debugging** - Log messages for debugging
-
-For the complete list of available host functions, their WASM names, and gas
-costs, see the [XLS-0102 specification](https://xls.xrpl.org/xls/XLS-0102-wasm-vm.html)
-or `detail/WasmVM.cpp` where they are registered via `WASM_IMPORT_FUNC2` macros.
-For method signatures, see `HostFunc.h`.
-
-## Gas Model
-
-Each host function has an associated gas cost. The gas cost is specified when
-registering the function in `detail/WasmVM.cpp`:
-
-```cpp
-WASM_IMPORT_FUNC2(i, getLedgerSqn, "get_ledger_sqn", hfs, 60);
-//                                                        ^^ gas cost
-```
-
-WASM execution is metered, and if the gas limit is exceeded, execution fails.
-
-## Entry Point
-
-The WASM module must export a function with the name defined by
-`ESCROW_FUNCTION_NAME` (currently `"finish"`). This function:
-
-- Takes no parameters (or parameters passed via host function calls)
-- Returns an `int32_t`:
-  - `1` (or positive): Escrow conditions are met, allow finish
-  - `0` (or negative): Escrow conditions are not met, reject finish
-
-## Adding a New Host Function
-
-To add a new host function, follow these steps:
-
-### 1. Add to HostFunc.h (Base Class)
-
-Add a virtual method declaration with a default implementation that returns an
-error:
-
-```cpp
-virtual Expected<ReturnType, HostFunctionError>
-myNewFunction(ParamType1 param1, ParamType2 param2)
-{
-    return Unexpected(HostFunctionError::INTERNAL);
-}
-```
-
-### 2. Add to HostFuncImpl.h (Declaration)
-
-Add the method override declaration in `WasmHostFunctionsImpl`:
-
-```cpp
-Expected<ReturnType, HostFunctionError>
-myNewFunction(ParamType1 param1, ParamType2 param2) override;
-```
-
-### 3. Implement in detail/HostFuncImpl\*.cpp
-
-Add the implementation in the appropriate file:
-
-```cpp
-Expected<ReturnType, HostFunctionError>
-WasmHostFunctionsImpl::myNewFunction(ParamType1 param1, ParamType2 param2)
-{
-    // Implementation using ctx (ApplyContext) for ledger access
-    return result;
-}
-```
-
-### 4. Add Wrapper to HostFuncWrapper.h
-
-Add the prototype and wrapper declaration:
-
-```cpp
-using myNewFunction_proto = int32_t(uint8_t const*, int32_t, ...);
-wasm_trap_t*
-myNewFunction_wrap(void* env, wasm_val_vec_t const* params, wasm_val_vec_t* results);
-```
-
-### 5. Implement Wrapper in detail/HostFuncWrapper.cpp
-
-Implement the C-style wrapper that bridges WASM to C++:
-
-```cpp
-wasm_trap_t*
-myNewFunction_wrap(void* env, wasm_val_vec_t const* params, wasm_val_vec_t* results)
-{
-    // Extract parameters from params
-    // Call hfs->myNewFunction(...)
-    // Set results and return
-}
-```
-
-### 6. Register in WasmVM.cpp
-
-Add the function registration in `setCommonHostFunctions()` or
-`createWasmImport()`:
-
-```cpp
-WASM_IMPORT_FUNC2(i, myNewFunction, "my_new_function", hfs, 100);
-//                                   ^^ WASM name       ^^ gas cost
-```
-
-> [!IMPORTANT]
-> New host functions MUST be amendment-gated in `WasmVM.cpp`.
-> Wrap the registration in an amendment check to ensure the function is only
-> available after the corresponding amendment is enabled on the network.
