 ### 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)):

+unfamiliar with Conan, then please read [this crash course](./docs/build/conan.md) or the official
+[Getting Started][conan-getting-started] walkthrough.
+
+#### Profiles
+
+We recommend that you install our Conan profiles:
 
 ```bash
-./conan/init.sh
+conan config install conan/profiles/ -tf $(conan config home)/profiles/
 ```
 
-That installs our [`global.conf`](./conan/global.conf), our Conan
-[profiles](./conan/profiles), and the `xrplf` remote that hosts some of our
-dependencies. It honours `CONAN_HOME` and never deletes an existing Conan home,
-so it is safe to re-run — it only overwrites the files it manages.
+You can check your Conan profile by running:
 
-> [!TIP]
-> In the [Nix development shell](./docs/build/nix.md#conan-configuration) this is
-> already done for you: the script runs on entry.
+```bash
+conan profile show
+```
 
-You can inspect the resulting profile with `conan profile show`. If it is not
-suitable for your environment, create a custom profile and pass it to Conan — see
-[Advanced Conan configuration](./docs/build/advanced_conan.md).
+If the default profile is not suitable for your environment, you can create a custom profile and pass it to Conan.
+More information on customizing Conan can be found in the [Advanced Conan configuration](./docs/build/advanced_conan.md).
+
+#### Add xrplf remote
+
+Run the following command to add the `xrplf` remote, which hosts some of our dependencies:
+
+```bash
+conan remote add --index 0 --force xrplf https://conan.xrplf.org/repository/conan/
+```

 not always strictly enforced and serve as a way to keep the codebase
 coherent rather than a set of _thou shalt not_ commandments.
 
-## 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.
-
 ## Formatting
 
-All code must conform to `clang-format`, according to the settings in
-[`.clang-format`](./.clang-format), unless the result would be unreasonably
-difficult to read or maintain. The `clang-format` version is pinned in
-[`.pre-commit-config.yaml`](./.pre-commit-config.yaml), so the
-[`pre-commit`](#pre-commit-hooks) hook always formats with the same version as
-CI. To demarcate lines that should be left as-is, surround them with comments

-### Older compilers
-
 Older compilers may fail to build the latest `develop` code: the codebase now
 relies on C++23 features and has been adjusted for `clang-tidy`.
 If the latest code doesn't build for you, update your build toolchain first.
 
-If updating isn't an option for you, we do accept pull requests that fix builds
-on older compilers, as long as the change is small and doesn't make the code
-harder to read. What we can't promise is that older compilers will keep working:
-only the versions in the table above are tested in CI, and we won't hold back
-the use of C++23 features or add invasive workarounds to keep an untested

 ### Choosing a different compiler
 
 A compiler can be chosen by providing its name with the `.#` prefix, e.g. `nix develop .#clang`.
-
-On Linux, `.#gcc` and `.#clang` provide the exact toolchain CI uses:
-the compiler (pinned in [`nix/packages.nix`](../../nix/packages.nix))
-rebuilt against the pinned custom glibc (see [`nix/compilers.nix`](../../nix/compilers.nix)).
-Building that toolchain the first time is slow unless it is fetched from a Nix binary cache.
-If you don't need the custom glibc, the Linux-only `.#gcc-plain` and `.#clang-plain`
-give you the stock nixpkgs compilers of the same versions.
-On macOS there is no custom glibc, so `.#gcc` and `.#clang` are already the plain nixpkgs toolchain,
-and the `-plain` variants do not exist.
-
+The `.#gcc` and `.#clang` shells provide the same GCC and Clang versions used in CI

-## Building xrpld in the Nix shell
+## Building xrpld with Nix
 
 Once inside the Nix development shell, follow the standard [build instructions](../../BUILD.md#steps). The Nix shell provides all necessary tools (CMake, Ninja, Conan, etc.).
 
-Coverage builds (`-Dcoverage=ON`) work in the `gcc` shell (and `gcc-plain` on Linux):
-each ships a `gcov` matching its compiler, since Nix's cc-wrapper does not expose one.
-The `clang` shells do not include `llvm-cov`, so use a `gcc` shell for coverage.
-
-## Conan configuration
-
-The shell runs [`conan/init.sh`](../../conan/init.sh) on entry, so
-[Set Up Conan](../../BUILD.md#set-up-conan) is already done for you. It installs
-into the shell's own Conan home: `CONAN_HOME=~/.conan2-nix`.
-
-### Prebuilt packages
-
-On **Linux**, the binaries on the `xrplf` remote are built in this same Nix
-environment — CI runs in Docker images that bundle the dev shell's toolchain (see
-[`nix/docker`](../../nix/docker)) — so `.#gcc` and `.#clang` can reuse them. The
-`-plain` shells do not match that toolchain's glibc, so binaries from the remote
-are not a reliable match there.
-
-On **macOS**, CI builds with Apple Clang, so the remote holds nothing for the Nix
-`clang` toolchain and dependencies are compiled locally. We do not publish
-Nix-built macOS binaries because a Conan package ID records the compiler version
-but not the nixpkgs revision.
-
-To compile everything from source, add `--build '*'` to the `conan install`
-command.

 To update `flake.lock` to the latest revision use `nix flake update` command.
 
-## Tooling snapshots
-
-The tool versions in each Nix environment are recorded in
-[`nix/check-tools/`](../../nix/check-tools) and verified by CI. If you change the
-environment (bump the CI image tag, update `flake.lock`, or edit the tool list in
-`bin/check-tools.sh`), CI fails until you regenerate and commit the affected
-snapshot — see [`nix/check-tools/README.md`](../../nix/check-tools/README.md).

 Common issues encountered when using the [Nix development shell](./nix.md), and
 how to resolve them.
 
-## `command not found: nix` after a macOS update
-
-If a shell suddenly can't find `nix` at all:
-
-```
-$ nix develop
-zsh: command not found: nix
-```
-
-then Nix is almost certainly still installed — only the shell hook that puts it
-on your `PATH` is gone. Confirm that first:
-
-```bash
-ls -l /nix/var/nix/profiles/default/bin/nix
-```
-
-If that exists, the installation is fine and this is purely a `PATH` problem.
-
-### Why it happens
-
-The installer does not touch your dotfiles. Instead it sources a setup script
-from the Nix store by editing **system-wide** rc files:
-
-| Shell | File the installer edits              |
-| ----- | ------------------------------------- |
-| bash  | `/etc/bashrc`, `/etc/bash.bashrc`     |
-| zsh   | `/etc/zshrc`                          |
-| fish  | `$__fish_sysconf_dir/conf.d/nix.fish` |
-
-macOS manages `/etc/zshrc`, so an OS update can replace it with the vendor copy
-and silently drop the Nix block. `/etc/bashrc` and the fish file usually survive,
-which is why the breakage often shows up in zsh only. You can verify this by
-diffing against the backup the installer left behind:
-
-```bash
-diff /etc/zshrc /etc/zshrc.backup-before-nix
-```
-
-If they are identical, the Nix snippet was wiped. This is upstream issue
-[NixOS/nix#3616](https://github.com/NixOS/nix/issues/3616).
-
-### Fix
-
-To unblock the current shell:
-
-```bash
-. /nix/var/nix/profiles/default/etc/profile.d/nix-daemon.sh
-```
-
-For a permanent fix, add the snippet to your **user** rc file rather than
-restoring `/etc/zshrc` — user dotfiles are not clobbered by OS updates:
-
-```bash
-cat >>~/.zshrc <<'EOF'
-
-# Nix
-if [ -e '/nix/var/nix/profiles/default/etc/profile.d/nix-daemon.sh' ]; then
-  . '/nix/var/nix/profiles/default/etc/profile.d/nix-daemon.sh'
-fi
-# End Nix
-EOF
-```
-
-The scripts guard against double-sourcing via `__ETC_PROFILE_NIX_SOURCED`, so
-this is safe even if a system-wide hook is later restored.
-
-> [!NOTE]
-> `/etc/zshrc` and `~/.zshrc` are only read by **interactive** zsh. If the
-> snippet is present but `zsh -c '…'`, a script, or an IDE terminal still can't
-> find `nix`, that shell is non-interactive — put the snippet in `~/.zshenv`
-> instead.
