+Format embedded shell snippets using the shfmt hook configured in
+.pre-commit-config.yaml.
+
+Two shapes are recognised:
+
+* YAML workflow/action files: literal block-scalar runs (`run: |`) and
+  single-line runs (`run: some command`). A single-line run is upgraded to
+  a `run: |` block scalar if shfmt's output spans multiple lines.
+
+* Markdown files: ``` ```bash ``` fenced code blocks.
+
+Any block that shfmt cannot parse is skipped with a warning on stderr, so
+the file is left untouched and surrounding blocks still get formatted.
+
+For each occurrence the body is dedented, written to a temp .sh file,
+formatted via `pre-commit run shfmt --files <temp>` (falling back to
+`prek`), then re-indented and written back in place.
+
+When invoked without arguments, every .yml/.yaml under .github/ plus every
+.md file in the repo is scanned. When invoked with file arguments (the
+pre-commit case), only those files are processed.

 ### Additions
 
+- `account_tx`: Added an optional `delegate` request object to filter delegated transactions. The object requires `delegate_filter`, which must be either `actor` for transactions owned by the requested account but signed by another account, or `authorizer` for transactions signed by the requested account on behalf of another account. The optional `counter_party` account narrows the results to a specific signer/delegate for `actor` or a specific owner/delegator for `authorizer`. Malformed `delegate`, `delegate_filter`, and `counter_party` values return standard invalid field errors, and invalid account IDs return `actMalformed`.
+  When paginating delegate-filtered queries, a marker from a delegate-filtered query includes a `delegate` flag and is only valid for follow-up requests that also supply `delegate` (mixing marker conventions returns `invalidParams`). Because filtering is applied after the ledger scan, a page may contain fewer results than `limit` (possibly zero) while still returning a marker, so callers must continue until no marker is present.
+
+- `ledger_entry`, `account_objects`: The `Delegate` ledger entry now includes an optional `DestinationNode` field, which stores the index into the authorized account's owner directory. This field is present on entries created after bidirectional directory tracking was introduced and may appear in RPC responses for those entries. ([#6681](https://github.com/XRPLF/rippled/pull/6681))
+
 - `server_definitions`: Added the following new sections to the response ([#6321](https://github.com/XRPLF/rippled/pull/6321)):
   - `TRANSACTION_FORMATS`: Describes the fields and their optionality for each transaction type, including common fields shared across all transactions.

+### Bugfixes
+
+- `get_aggregate_price`: Duplicate entries in the `oracles` request array are now ignored. [#6586](https://github.com/XRPLF/rippled/pull/6586)
+- Peer Crawler: The `port` field in `overlay.active[]` now consistently returns an integer instead of a string for outbound peers. [#6318](https://github.com/XRPLF/rippled/pull/6318)
+- `ping`: The `ip` field is no longer returned as an empty string for proxied connections without a forwarded-for header. It is now omitted, consistent with the behavior for identified connections. [#6730](https://github.com/XRPLF/rippled/pull/6730)
+- gRPC `GetLedgerDiff`: Fixed error message that incorrectly said "base ledger not validated" when the desired ledger was not validated. [#6730](https://github.com/XRPLF/rippled/pull/6730)
+- `account_channels`: The `destination_account` field now returns an error if the value is not a string. [#6529](https://github.com/XRPLF/rippled/pull/6529)
+- `subscribe`: The `taker` field in the `books` array now returns an error if the value is not a string. [#6529](https://github.com/XRPLF/rippled/pull/6529)

-may also need to apply the required [tweaks](#conan-profile-tweaks) to this
-default profile.
-
-### Patched recipes
-
-The recipes in Conan Center occasionally need to be patched for compatibility
-with the latest version of `xrpld`. We maintain a fork of the Conan Center
-[here](https://github.com/XRPLF/conan-center-index/) containing the patches.
-
-To ensure our patched recipes are used, you must add our Conan remote at a
-higher index than the default Conan Center remote, so it is consulted first. You
-can do this by running:
-
-```bash
-conan remote add --index 0 xrplf https://conan.ripplex.io
-```
-
-Alternatively, you can pull the patched recipes into the repository and use them
-locally:
-
-```bash
-# Extract the version number from the lockfile.
-function extract_version {
-  version=$(cat conan.lock | sed -nE "s@.+${1}/(.+)#.+@\1@p" | head -n1)
-  echo ${version}

-
-# Define which recipes to export.

-
-In the case we switch to a newer version of a dependency that still requires a
-patch, it will be necessary for you to pull in the changes and re-export the
-updated dependencies with the newer version. However, if we switch to a newer
-version that no longer requires a patch, no action is required on your part, as
-the new recipe will be automatically pulled from the official Conan Center.

-### Conan profile tweaks
-
-#### Missing compiler version
-
-If you see an error similar to the following after running `conan profile show`:
-
-```bash
-ERROR: Invalid setting '17' is not a valid 'settings.compiler.version' value.
-Possible values are ['5.0', '5.1', '6.0', '6.1', '7.0', '7.3', '8.0', '8.1',

-'15.0', '16', '16.0']
-Read "http://docs.conan.io/2/knowledge/faq.html#error-invalid-setting"
-```
-
-you need to amend the list of compiler versions in
-`$(conan config home)/settings.yml`, by appending the required version number(s)
-to the `version` array specific for your compiler. For example:
-
-```yaml
-apple-clang:
-  version:
-    [
-      "5.0",
-      "5.1",
-      "6.0",
-      "6.1",
-      "7.0",
-      "7.3",
-      "8.0",
-      "8.1",
-      "9.0",
-      "9.1",
-      "10.0",
-      "11.0",
-      "12.0",
-      "13",
-      "13.0",
-      "13.1",
-      "14",
-      "14.0",
-      "15",
-      "15.0",
-      "16",
-      "16.0",
-      "17",
-      "17.0",
-    ]
-```
-
-#### Multiple compilers
-
-If you have multiple compilers installed, make sure to select the one to use in
-your default Conan configuration **before** running `conan profile detect`, by
-setting the `CC` and `CXX` environment variables.
-
-For example, if you are running MacOS and have [homebrew
-LLVM@18](https://formulae.brew.sh/formula/llvm@18), and want to use it as a
-compiler in the new Conan profile:
-
-```bash
-export CC=$(brew --prefix llvm@18)/bin/clang
-export CXX=$(brew --prefix llvm@18)/bin/clang++
-conan profile detect
-```
-
-You should also explicitly set the path to the compiler in the profile file,
-which helps to avoid errors when `CC` and/or `CXX` are set and disagree with the
-selected Conan profile. For example:
-
-```text
-[conf]
-tools.build:compiler_executables={'c':'/usr/bin/gcc','cpp':'/usr/bin/g++'}
-```
-
-#### Multiple profiles
-
-You can manage multiple Conan profiles in the directory
-`$(conan config home)/profiles`, for example renaming `default` to a different
-name and then creating a new `default` profile for a different compiler.
-
-#### Select language
-
-The default profile created by Conan will typically select different C++ dialect
-than C++20 used by this project. You should set `20` in the profile line
-starting with `compiler.cppstd=`. For example:
-
-```bash
-sed -i.bak -e 's|^compiler\.cppstd=.*$|compiler.cppstd=20|' $(conan config home)/profiles/default
-```
-
-#### Select standard library in Linux
-
-**Linux** developers will commonly have a default Conan [profile][] that
-compiles with GCC and links with libstdc++. If you are linking with libstdc++
-(see profile setting `compiler.libcxx`), then you will need to choose the
-`libstdc++11` ABI:
-
-```bash
-sed -i.bak -e 's|^compiler\.libcxx=.*$|compiler.libcxx=libstdc++11|' $(conan config home)/profiles/default
-```
-
-#### Select architecture and runtime in Windows
-
-**Windows** developers may need to use the x64 native build tools. An easy way
-to do that is to run the shortcut "x64 Native Tools Command Prompt" for the
-version of Visual Studio that you have installed.
-
-Windows developers must also build `xrpld` and its dependencies for the x64
-architecture:
-
-```bash
-sed -i.bak -e 's|^arch=.*$|arch=x86_64|' $(conan config home)/profiles/default
-```
-
-**Windows** developers also must select static runtime:
-
-```bash
-sed -i.bak -e 's|^compiler\.runtime=.*$|compiler.runtime=static|' $(conan config home)/profiles/default
-```
-
-#### Clang workaround for grpc
-
-If your compiler is clang, version 19 or later, or apple-clang, version 17 or
-later, you may encounter a compilation error while building the `grpc`
-dependency:
-

+[Unity builds][unity-build] may be faster for the first build (at the cost of much more
 memory) since they concatenate sources into fewer translation units. Non-unity
 builds may be faster for incremental builds, and can be helpful for detecting
 `#include` omissions.
 
+### Verifying headers
+
+The regular build only compiles `.cpp` files, so a header is only ever checked
+through whatever translation unit happens to include it. A header that forgets
+an `#include` is not caught as long as every `.cpp` that uses it includes its
+missing dependency first. The `verify_headers` option (ON by default) adds a
+`verify-headers` target that compiles every header on its own, which fails if a
+header is not self-contained:
+
+```bash
+cmake --build . --target verify-headers
+```
+
+The per-header objects are excluded from the `all` target, so a normal build
+never compiles them; they are built only through `verify-headers`. The generated
+translation units do appear in `compile_commands.json`, so clang-tidy (and
+clangd and IDEs) can lint each header on its own. Pass `-Dverify_headers=OFF` to
+omit them entirely.

+## Pre-commit hooks
+
+We use the [`pre-commit`](https://pre-commit.com/) framework to run the
+formatting and linting tools that keep the codebase consistent. `pre-commit`
+runs each tool configured in
+[`.pre-commit-config.yaml`](./.pre-commit-config.yaml) in its own isolated
+environment, so you don't need to install most of the individual tools
+yourself. The version of each hook sourced from an external repository
+(`clang-format`, `gersemi`, etc.) is pinned in that file, so running the hooks
+locally uses exactly the same versions as CI. A few `local` hooks — most notably
+`clang-tidy` — run tools from your own environment; see
+[Installing clang-tidy](#installing-clang-tidy) for how to get those.
+
+To get started, install `pre-commit` and enable the git hook scripts:
+
+```bash
+pip install pre-commit
+pre-commit install
+```
+
+Once installed, the hooks run automatically on your staged files every time you
+`git commit`. You can also run them on demand:
+
+```bash
+# Run all hooks against only the staged files
+pre-commit run
+
+# Run all hooks against every file in the repository
+pre-commit run --all-files
+
+# Run a single hook (e.g. clang-format) against all files
+pre-commit run clang-format --all-files
+```
+
+The hooks configured in this repository include, among others:
+
+- `clang-format` — C++/proto formatting (see [Formatting](#formatting))
+- `clang-tidy` — C++ static analysis (see [Clang-tidy](#clang-tidy)); opt in with `TIDY=1`
+- `fix-include-style`, `fix-pragma-once`, `check-doxygen-style` — C++ hygiene
+- `gersemi` — CMake formatting
+- `prettier`, `black`, `shfmt` — formatting for JavaScript/JSON/Markdown, Python, and shell
+- `cspell` — spell checking
+
+The same hooks run in CI on every pull request, so running them locally before
+you push helps you avoid CI failures.

+### Installing clang-tidy
+
+See the [environment setup guide](./docs/build/environment.md#clang-tidy) for how to get clang-tidy.
+
 ### 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.
 
+#### Via pre-commit (recommended)
+
+If you have already installed the [`pre-commit`](#pre-commit-hooks) hooks, you can run clang-tidy on your staged files using:
+
+```
+TIDY=1 pre-commit run clang-tidy
+```
+
+This runs clang-tidy locally with the same configuration/flags as CI, scoped to your staged C++ files. The `TIDY=1` environment variable is required to opt in — without it the hook is skipped.
+
+You can also have clang-tidy run automatically on every `git commit` by setting `TIDY=1` in your shell environment:
+
+```
+export TIDY=1
+```
+
+With this set, the hook will run as part of `git commit` alongside the other pre-commit checks.
+
+#### Manually
+
 Then run clang-tidy on your local changes:
 
 ```
-run-clang-tidy -p build src tests
+run-clang-tidy -p build -allow-no-checks src tests
 ```
 
-This will check all source files in the `src` and `tests` directories using the compile commands from your `build` directory.
+This will check all source files in the `src`, `include` and `tests` directories using the compile commands from your `build` directory.
+If you wish to automatically fix whatever clang-tidy finds _and_ is capable of fixing, add `-fix -format` to the above command:
+
+```
+run-clang-tidy -p build -quiet -fix -format -allow-no-checks src tests
+```
+
+`-format` reformats the fixed code with [`.clang-format`](./.clang-format); without it the fixes are inserted in LLVM style and the `clang-format` hook rewrites them afterwards.

 - Read [the levelization document](.github/scripts/levelization) to get an idea of the internal dependency graph.
 - In the big picture, the `main` function constructs an `ApplicationImp` object, which implements the `Application` virtual interface. Almost every component in the application takes an `Application&` parameter in its constructor, typically named `app` and stored as a member variable `app_`. This allows most components to depend on any other component.

-### Responsible Disclosure
-
-If you discover a vulnerability or potential threat, or if you _think_
-you have, please reach out by dropping an email using the contact
-information below.
-
-Your report should include the following:
-
-- Your contact information (typically, an email address);
-- The description of the vulnerability;
-- The attack scenario (if any);
-- The steps to reproduce the vulnerability;
-- Any other relevant details or artifacts, including code, scripts or patches.

-## Report Handling Process
-
-Please report the bug directly to us and limit further disclosure. If you want to prove that you knew the bug as of a given time, consider using a cryptographic pre-commitment: hash the content of your report and publish the hash on a medium of your choice (e.g. on Twitter or as a memo in a transaction) as "proof" that you had written the text at a given point in time.
-
-Once we receive a report, we:
-
-1. Assign two people to independently evaluate the report;
-2. Consider their recommendations;
-3. If action is necessary, formulate a plan to address the issue;
-4. Communicate privately with the reporter to explain our plan.
-5. Prepare, test and release a version which fixes the issue; and
-6. Announce the vulnerability publicly.
-
-We will triage and respond to your disclosure within 24 hours. Beyond that, we will work to analyze the issue in more detail, formulate, develop and test a fix.
-
-While we commit to responding with 24 hours of your initial report with our triage assessment, we cannot guarantee a response time for the remaining steps. We will communicate with you throughout this process, letting you know where we are and keeping you updated on the timeframe.

-1. **In scope**. Only bugs in software under the scope of the program qualify. Currently, that means `rippled`, `xrpl.js`, `xrpl-py`, `xrpl4j`.
-2. **Relevant**. A security issue, posing a danger to user funds, privacy, or the operation of the XRP Ledger.
-3. **Original and previously unknown**. Bugs that are already known and discussed in public do not qualify. Previously reported bugs, even if publicly unknown, are not eligible.
-4. **Specific**. We welcome general security advice or recommendations, but we cannot pay bounties for that.
-5. **Fixable**. There has to be something we can do to permanently fix the problem. Note that bugs in other people’s software may still qualify in some cases. For example, if you find a bug in a library that we use which can compromise the security of software that is in scope and we can get it fixed, you may qualify for a bounty.
-6. **Unused**. If you use the exploit to attack the XRP Ledger, you do not qualify for a bounty. If you report a vulnerability used in an ongoing or past attack and there is specific, concrete evidence that suggests you are the attacker we reserve the right not to pay a bounty.
-
-The amount paid varies dramatically. Vulnerabilities that are harmless on their own, but could form part of a critical exploit will usually receive a bounty. Full-blown exploits can receive much higher bounties. Please don’t hold back partial vulnerabilities while trying to construct a full-blown exploit. We will pay a bounty to anyone who reports a complete chain of vulnerabilities even if they have reported each component of the exploit separately and those vulnerabilities have been fixed in the meantime. However, to qualify for a the full bounty, you must to have been the first to report each of the partial exploits.

+"""
+Reduce run-clang-tidy output to its unique errors.
+
+It does two things:
+
+  1. Filters the raw output down to diagnostics and their source-context lines
+     (the indented "  103 | ..." / "      | ^" lines clang-tidy prints),
+     matching the "path:line:col: error:" diagnostic shape.
+
+  2. Deduplicates. The same diagnostic in a header is reported once per
+     translation unit that includes it, so identical error blocks are collapsed
+     to their first occurrence.
+
+An "error block" is an "error:" line together with the indented context lines
+and any "note:" lines that follow it (up to the next "error:" line). Blocks are
+compared as a whole, so an error stays attached to its own context, and
+first-occurrence order is preserved.
+
+The deduplicated output goes to stdout; a summary of unique error counts per
+check is printed to stderr.
+
+Usage:
+  bin/filter-clang-tidy.py [INPUT_FILE]            # read from file, or

+# progress lines whose paths contain "error" as diagnostics, e.g.

+Check C++ Doxygen comment style.
+
+Enforces the house convention for documentation comments:
+
+  * Use ``/** ... */`` blocks, not ``///``, ``//!`` or ``/*! ... */``; a plain
+    ``/* ... */`` that contains Doxygen commands is a doc comment missing its
+    second star. Trailing member-after comments use ``///<`` (not ``//!<``,
+    ``/*!< ... */`` or ``/**< ... */`` -- the block forms get reflowed and
+    mis-attached by clang-format on packed enum values, the line form does not).
+  * ``/**`` sits alone on its line; the closing ``*/`` sits alone on its line.
+  * Every content line is prefixed with `` * `` (no bare-indented continuation).
+  * The first content line is flush (not over-indented).
+  * Doxygen commands use the ``@cmd`` form, not ``\\cmd``.
+  * Use ``@return`` / ``@throws`` rather than prose ``Returns:`` / ``Throws:``.
+  * A plain ``//`` comment carrying a block-level ``@command`` (``@param``,
+    ``@return``, ``@see``, ...) is documentation and must be a ``/** ... */``
+    block (Doxygen ignores ``//``).
+  * Use canonical command spellings: ``@return`` (not ``@returns``),
+    ``@throws`` (not ``@throw``), ``@see`` (not ``@sa``).
+  * Order block tags ``@tparam`` -> ``@param`` -> ``@return``. (Whether
+    ``@param`` order matches the signature is not checked here -- too fragile to
+    parse; Doxygen's WARN_IF_DOC_ERROR covers name mismatches.)
+  * One-liners are expanded to three lines, EXCEPT bare markers ``@{`` / ``@}``
+    / ``@cond [label]`` / ``@endcond`` / ``@file [name]`` which stay on one line.
+
+Left intentionally alone (recognized, valid Doxygen that is not this style's
+concern):
+
+  * ``///<`` trailing "member-after" comments (the house form).
+  * Divider lines made only of slashes (``//////////``).
+  * Plain ``/* ... */`` (non-Doxygen) comments.
+
+Usage:
+    check_doxygen_style.py [FILE ...]      # explicit files
+    check_doxygen_style.py                 # default: src/ and include/ trees
+
+Exit status is non-zero if any violation is found.

-   Configure sanitizers based on environment variables.
+   Apply sanitizer flags built by the Conan profile.
 
-   This module reads the following environment variables:
-   - SANITIZERS: The sanitizers to enable. Possible values:
-     - "address"
-     - "address,undefinedbehavior"
-     - "thread"
-     - "thread,undefinedbehavior"
-     - "undefinedbehavior"
+   Parsing, validation, and flag construction are performed in conan/profiles/sanitizers.
+   This module reads the following CMake variables injected by the Conan toolchain via extra_variables:
 
-   The compiler type and platform are detected in CompilationEnv.cmake.
-   The sanitizer compile options are applied to the 'common' interface library
-   which is linked to all targets in the project.
+   - SANITIZERS:                The active sanitizers (e.g. "address,undefinedbehavior").
+   - SANITIZERS_COMPILER_FLAGS: Space-separated compiler flags.
+   - SANITIZERS_LINKER_FLAGS:   Space-separated linker flags.
 
-   Internal flag variables set by this module:
-
-   - SANITIZER_TYPES: List of sanitizer types to enable (e.g., "address",
-     "thread", "undefined"). And two more flags for undefined behavior sanitizer (e.g., "float-divide-by-zero", "unsigned-integer-overflow").
-     This list is joined with commas and passed to -fsanitize=<list>.
-
-   - SANITIZERS_COMPILE_FLAGS: Compiler flags for sanitizer instrumentation.
-     Includes:
-     * -fno-omit-frame-pointer: Preserves frame pointers for stack traces
-     * -O1: Minimum optimization for reasonable performance
-     * -fsanitize=<types>: Enables sanitizer instrumentation
-     * -fsanitize-ignorelist=<path>: (Clang only) Compile-time ignorelist
-     * -mcmodel=large/medium: (GCC only) Code model for large binaries
-     * -Wno-stringop-overflow: (GCC only) Suppresses false positive warnings
-     * -Wno-tsan: (For GCC TSAN combination only) Suppresses atomic_thread_fence warnings
-
-   - SANITIZERS_LINK_FLAGS: Linker flags for sanitizer runtime libraries.
-     Includes:
-     * -fsanitize=<types>: Links sanitizer runtime libraries
-     * -mcmodel=large/medium: (GCC only) Matches compile-time code model
-
-   - SANITIZERS_RELOCATION_FLAGS: (GCC only) Code model flags for linking.
-     Used to handle large instrumented binaries on x86_64:
-     * -mcmodel=large: For AddressSanitizer (prevents relocation errors)
-     * -mcmodel=medium: For ThreadSanitizer (large model is incompatible)
+   The flags are applied to the 'common' interface library which is linked to all targets in the project.
