 ## Breaking Changes
 
-### Modifications to `tx` and `account_tx`
-
-In API versions 1 and 2, the `tx_json` field in `tx` and `account_tx` responses includes server-added lower-case fields (`date`, `ledger_index`, and `ctid`) that are not part of the canonical signed transaction. In API version 3, these fields are removed from `tx_json` and are only present at the top-level `result` object.
-
-- **Before (API v1 and v2)**: The `tx_json` object in the response contained `date`, `ledger_index`, and `ctid` fields alongside the canonical PascalCase transaction fields.
-- **After (API v3)**: The `tx_json` object contains only the canonical signed transaction fields. The `date`, `ledger_index`, and `ctid` fields appear exclusively at the top-level `result` object.
-
 ### Modifications to `amm_info`
 
 The order of error checks has been changed to provide more specific error messages. ([#4924](https://github.com/XRPLF/rippled/pull/4924))

-## 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.

-// Allocator interaction note:
-// - This facility invokes glibc's malloc_trim(0) on Linux/glibc to request that
-//   ptmalloc return free heap pages to the OS.
-// - If an alternative allocator (e.g. jemalloc or tcmalloc) is linked or
-//   preloaded (LD_PRELOAD), calling glibc's malloc_trim typically has no effect
-//   on the *active* heap. The call is harmless but may not reclaim memory
-//   because those allocators manage their own arenas.
-// - Only glibc sbrk/arena space is eligible for trimming; large mmap-backed
-//   allocations are usually returned to the OS on free regardless of trimming.

-/**
- * @brief Attempt to return freed memory to the operating system.
- *
- * On Linux with glibc malloc, this issues ::malloc_trim(0), which may release
- * free space from ptmalloc arenas back to the kernel. On other platforms, or if
- * a different allocator is in use, this function is a no-op and the report will
- * indicate that trimming is unsupported or had no effect.
- *
- * @param tag     Identifier for logging/debugging purposes.
- * @param journal Journal for diagnostic logging.
- * @return Report containing before/after metrics and the trim result.
- *
- * @note If an alternative allocator (jemalloc/tcmalloc) is linked or preloaded,
- *       calling glibc's malloc_trim may have no effect on the active heap. The
- *       call is harmless but typically does not reclaim memory under those
- *       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
- *       independently of trimming.
- *
- * @note Intended for use after operations that free significant memory (e.g.,
- *       cache sweeps, ledger cleanup, online delete). Consider rate limiting.
