-This file provides guidance to AI coding agents (Claude Code, and other AGENTS.md-compatible tools) when working with code in this repository.
-
-## Build
-
-Required on Linux/macOS: use the Nix devshell, which sets up the compiler, Conan, ccache, and (optionally) Rust automatically.
-
-```bash
-nix develop
-```
-
-For alternate devshell variants (specific compiler, no-compiler, coverage), see [docs/build/nix.md](./docs/build/nix.md). For the manual build steps, CMake options, and protocol codegen commands, see [BUILD.md](./BUILD.md) (`## Steps`, `## Options`, `## Code generation`).
-
-Rust crate tests (independent of the CMake build): `cargo test --manifest-path crates/Cargo.toml --workspace` (CI uses `cargo nextest`).
-
-## Testing
-
-Unit tests are a custom framework built into the `xrpld` binary itself (not Boost.Test/GTest/Catch); see [CONTRIBUTING.md](./CONTRIBUTING.md#unit-tests) for the basic invocation. Notes not covered there:
-
-- A suite's `--unittest` name is built from the arguments to its `BEAST_DEFINE_TESTSUITE`/`BEAST_DEFINE_TESTSUITE_PRIO` macro (usually at the bottom of the test file), in reverse order and joined with `.`: `BEAST_DEFINE_TESTSUITE(Credentials, app, xrpl)` → `xrpl.app.Credentials`.
-- `--unittest-arg` does nothing — don't use it.
-- Tests that run offline in under a minute should be automatic `--unittest` suites; anything else is a manual/integration test.
-- New tests should be written using `gtest` under `src/tests/` unless that isn't possible, in which case fall back to the legacy Beast framework under `src/test/`. `tests/` (top-level) holds integration tests exercised against `libxrpl`/`xrpld`.
-
-## Lint/Format
-
-See [CONTRIBUTING.md](./CONTRIBUTING.md#pre-commit-hooks) for `pre-commit` setup and [CONTRIBUTING.md](./CONTRIBUTING.md#clang-tidy) for `clang-tidy` (opt-in, needs local `clang-tidy` and generated headers).
-
-## Code Style
-
-New file placement and header levelization: see [CONTRIBUTING.md](./CONTRIBUTING.md#before-making-a-pull-request). Braces, whitespace, member order, and other conventions: see [docs/CodingStyle.md](./docs/CodingStyle.md). `XRPL_ASSERT`/`UNREACHABLE` contracts: see [CONTRIBUTING.md](./CONTRIBUTING.md#contracts-and-instrumentation).

-## Architecture
-
-Paths below reflect the current layout; update this section if modularization moves a subsystem to a different directory.
-
-- `include/xrpl/` + `src/libxrpl/` — the core protocol library: ledger, shamap, consensus, crypto, json, resource, nodestore, rdb, peerfinder, and `tx/` (transaction application: `Transactor.cpp`, `applySteps.cpp`, invariants, payment paths). `tx/transactors/` has one file per transaction type, grouped by subsystem: `escrow/`, `vault/`, `lending/`, `sponsor/`, `nft/`, `token/` (MPT), `payment_channel/`, `permissioned_domain/`, `dex/`, `oracle/`, `did/`, `credentials/`, `bridge/`, `check/`, `delegate/`, `account/`, `system/`. Any change to transaction-processing behavior must be gated behind an Amendment.
-- `src/xrpld/` — the server application built on top of `libxrpl`: `app`, `core`, `overlay` (P2P networking), `peerfinder`, `perflog`, `rpc`, `shamap`. `main` builds an `ApplicationImp` implementing `Application`; most components hold a reference to it (`app_`), giving broad cross-component access — expect to trace call chains through `Application&`.
-- `src/test/` — unit tests mirroring the subsystems above, plus `jtx/` (the transaction-building test DSL — e.g. `jtx/escrow.h`, `jtx/vault.h`, `jtx/sponsor.h`, `jtx/permissioned_dex.h`) and `unit_test/` (the custom test framework itself, derived from Beast).
-- `src/tests/` — unit tests for `libxrpl` written in `gtest`, gradually replacing the `src/test` equivalents.
-- `crates/` — a Rust workspace (only built with `-Dxrpld -Drust=ON`) bridged into C++ via `cxxbridge`/the `cxx` crate; currently just a `hello_world` interop scaffold. Requires the Rust toolchain pinned in `rust-toolchain.toml` (the Nix devshell provides it automatically).

-Version 3.5.0 is not yet released.
+This section contains changes targeting a future version.
 
-### Additions in 3.5.0
+### Additions
 
-- `subscribe`, `unsubscribe`: Added an optional `mpt_issuances` request field, an array of MPT issuance IDs (hex strings). Subscribers receive a message with `type` `mptTransaction` for each validated transaction whose metadata affects a subscribed issuance; the message has the same fields as the `transactions` stream. MPT issuance subscriptions count toward the per-connection subscription limit. An empty array, a non-array value, or an invalid ID returns `invalidParams`. ([#5671](https://github.com/XRPLF/rippled/pull/5671))
-
-## XRP Ledger server version 3.4.0
-
-Version 3.4.0 is not yet released. These changes are available in the 3.4.0 beta releases.
-
-### Additions in 3.4.0
-
-- `ledger`: `nftoken_id`, `nftoken_ids`, and `offer_id` are now included in transaction metadata when transactions are expanded (`expand`, or admin-only `full`), matching the `tx`, `account_tx`, and `subscribe` (`transactions` stream) responses. ([#5706](https://github.com/XRPLF/rippled/pull/5706))
-
-### Bugfixes in 3.4.0
-
-- `sign`, `sign_for`, `submit`: `signature_target` now returns `invalidParams` unless it names `CounterpartySignature` or `SponsorSignature`. It previously accepted any inner object field, such as `Book` or `NFToken`, and signed into it.
-- `sign`, `sign_for`, `submit`, `submit_multisigned`: With `fixCleanup3_4_0` enabled, a signature in `CounterpartySignature` or `SponsorSignature` covers a different prefix than the transaction's own signature, so a signature can no longer be moved from one of those roles into another. Clients that build these signatures themselves must use the new prefixes: `CPT` and `CPM` (single- and multi-signing) for `CounterpartySignature`, and `SPN` and `SPM` for `SponsorSignature`.
-- `get_aggregate_price`: Duplicate entries in the `oracles` request array are now ignored. [#6586](https://github.com/XRPLF/rippled/pull/6586)
-- `vault_info`: Errors now identify what the request got wrong instead of reporting every failure as the unregistered token `malformedRequest`, and the `error`, `error_code` and `error_message` fields now agree with each other. An invalid `vault_id` or `seq` returns `invalidParams`, an invalid `owner` returns `actMalformed`, and a request that mixes `vault_id` with `owner`/`seq` or supplies neither returns `invalidParams` with a message naming the accepted combinations. [#8015](https://github.com/XRPLF/rippled/pull/8015)
-- `vault_info`: A well-formed all-zero `vault_id` now returns `entryNotFound` instead of being rejected as malformed, and `entryNotFound` responses now include `error_code` and `error_message`. Clients that request `ripplerpc` 3.0 or above therefore receive HTTP 400 with that error rather than HTTP 200. [#8015](https://github.com/XRPLF/rippled/pull/8015)
-- `vault_info`: `vault_id` and `owner` must now be strings, matching how `ledger_entry` reads the same fields. An object or an array in either field previously produced an internal error, and a number was silently converted to its decimal text; `vault_id` now returns `invalidParams` and `owner` returns `actMalformed`. [#8015](https://github.com/XRPLF/rippled/pull/8015)
-- `gateway_balances`: The `account` and `ident` fields now return an `invalidParams` error if the value is not a string, instead of an `internal` error. [#7655](https://github.com/XRPLF/rippled/pull/7655)
-- `account_lines`: The `peer` field now returns an error if the value is not a string. [#7728](https://github.com/XRPLF/rippled/pull/7728)
-- `ledger`: `delivered_amount` is now included in the metadata of successful `AccountDelete` transactions when transactions are expanded (`expand`, or admin-only `full`). Previously it was only added for `Payment` and `CheckCash`, which made `ledger` inconsistent with `tx` and `account_tx`. [#5706](https://github.com/XRPLF/rippled/pull/5706)
-- `noripple_check`: The `transactions` field is no longer included in error responses; it is still returned (possibly as an empty array) whenever `transactions` is `true` and the request succeeds. A malformed `account` is now rejected before the ledger is looked up, so that error response no longer carries the `ledger_hash`, `ledger_index`, and `validated` fields ([#6303](https://github.com/XRPLF/rippled/pull/6303)).

-## XRP Ledger server version 3.3.0

-
-### Additions in 3.3.0
-
-- `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.

-### Rust crates
-
-The Rust crates in `crates/` are only part of the build when `rust` is ON. With
-`-Drust=OFF` (the default) the `crates` directory is not added to the build, no
-cxxbridge bindings are generated, and the C++ tests that exercise the Rust
-interop are not compiled — so no Rust toolchain is needed. CI builds always pass
-`-Drust=ON`.
-
-With `-Drust=ON` you need one extra dependency: a Rust toolchain (`cargo`,
-`rustc`) matching the channel pinned in
-[`rust-toolchain.toml`](./rust-toolchain.toml), which compiles the crates and
-generates the cxxbridge bindings. It is provided by the
-[Nix development shell](./docs/build/nix.md), so `-Drust=ON` works there without
-any extra setup; otherwise install it as described in
-[Rust](./docs/build/environment.md#rust).
-
-The crates also have their own Rust unit tests. Those are run with `cargo` and
-need only the Rust toolchain, independently of CMake and of the `rust` option
-(CI runs them with `cargo nextest`):

 ### Releases
 
-Releases, release branches, and merging releases back into `develop`
-are described in [RELEASING.md](./RELEASING.md).
+All releases, including release candidates and betas, are handled
+differently from typical PRs. Most importantly, never use
+the Github UI to merge a release.
+
+Xrpld uses a linear workflow model that can be summarized as:
+
+1. In between releases, developers work against the `develop` branch.
+2. Periodically, a maintainer will build and tag a beta version from
+   `develop`, which is pushed to `release`.
+   - Betas are usually released every two to three weeks, though that
+     schedule can vary depending on progress, availability, and other
+     factors.
+3. When the changes in `develop` are considered stable and mature enough
+   to be ready to release, a release candidate (RC) is built and tagged
+   from `develop`, and merged to `release`.
+   - Further development for that release (primarily fixes) then
+     continues against `release`, while other development continues on
+     `develop`. Effectively, `release` is forked from `develop`. Changes
+     to `release` must be reverse merged to `develop`.
+4. When the candidate has passed testing and is ready for release, the
+   final release is merged to `master`.
+5. If any issues are found post-release, a hotfix / point release may be
+   created, which is merged to `master`, and then reverse merged to
+   `develop`.
+
+#### Betas, and the first release candidate
+
+##### Preparing the `develop` branch
+
+1. Optimally, the `develop` branch will be ready to go, with all
+   relevant PRs already merged.
+2. If there are any PRs pending, merge them **BEFORE** preparing the beta.
+   1. If only one or two PRs need to be merged, merge those PRs [as
+      normal](#when-and-how-to-merge-pull-requests), updating the second
+      one, and waiting for CI to finish in between.
+   2. If there are several pending PRs, do not use the Github UI,
+      because the delays waiting for CI in between each merge will be
+      unnecessarily onerous. (Incidentally, this process can also be
+      used to merge if the Github UI has issues.) Merge each PR branch
+      directly to a `release-next` on your local machine and create a single
+      PR, then push your branch to `develop`.
+      1. Squash the changes from each PR, one commit each (unless more
+         are needed), being sure to sign each commit and update the
+         commit message to include the PR number. You may be able to use
+         a fast-forward merge for the first PR.
+      2. Push your branch.
+      3. Continue to [Making the release](#making-the-release) to update
+         the version number, etc.
+
+      The workflow may look something like:
+
+```
+git fetch --multiple upstreams user1 user2 user3 [...]
+git checkout -B release-next --no-track upstream/develop
+
+# Only do an ff-only merge if pr-branch1 is either already
+# squashed, or needs to be merged with separate commits,
+# and has no merge commits.
+# Use -S on the ff-only merge if pr-branch1 isn't signed.
+git merge [-S] --ff-only user1/pr-branch1
+
+git merge --squash user2/pr-branch2
+git commit -S # Use the commit message provided on the PR
+
+git merge --squash user3/pr-branch3
+git commit -S # Use the commit message provided on the PR
+
+[...]
+
+# Make sure the commits look right
+git log --show-signature "upstream/develop..HEAD"
+
+git push --set-upstream origin
+
+# Continue to "Making the release" to update the version number, so
+# everything can be done in one PR.
+```
+
+You can also use the [squash-branches] script.
+
+You may also need to manually close the open PRs after the changes are
+merged to `develop`. Be sure to include the commit ID.
+
+##### Making the release
+
+This includes, betas, and the first release candidate (RC).
+
+1. If you didn't create one [preparing the `develop`
+   branch](#preparing-the-develop-branch), Ensure there is no old
+   `release-next` branch hanging around. Then make a `release-next`
+   branch that only changes the version number. e.g.
+
+```
+git fetch upstreams
+
+git checkout --no-track -B release-next upstream/develop
+
+v="A.B.C-bD"
+build=$( find -name BuildInfo.cpp )
+sed 's/\(^.*versionString =\).*$/\1 "'${v}'"/' ${build} > version.cpp && mv -vi version.cpp ${build}
+
+git diff
+
+git add ${build}
+
+git commit -S -m "Set version to ${v}"
+
+# You could use your "origin" repo, but some CI tests work better on upstream.
+git push upstream-push
+git fetch upstreams
+git branch --set-upstream-to=upstream/release-next
+```
+
+You can also use the [update-version] script. 2. Create a Pull Request for `release-next` with **`develop`** as
+the base branch.
+
+1.  Use the title "[TRIVIAL] Set version to X.X.X-bX".
+2.  Instead of the default description template, use the following:
+
+```
+## High Level Overview of Change
+
+This PR only changes the version number. It will be merged as
+soon as Github CI actions successfully complete.
+```
+
+3. Wait for CI to successfully complete, and get someone to approve
+   the PR. (It is safe to ignore known CI issues.)
+4. Push the updated `develop` branch using your `release-next`
+   branch. **Do not use the Github UI. It's important to preserve
+   commit IDs.**
+
+```
+git push upstream-push release-next:develop
+```
+
+5. In the unlikely event that the push fails because someone has merged
+   something else in the meantime, rebase your branch onto the updated
+   `develop` branch, push again, and go back to step 3.
+6. Ensure that your PR against `develop` is closed. Github should do it
+   automatically.
+7. Once this is done, forward progress on `develop` can continue
+   (other PRs may be merged).
+8. Now create a Pull Request for `release-next` with **`release`** as
+   the base branch. Instead of the default template, reuse and update
+   the message from the previous release. Include the following verbiage
+   somewhere in the description:
+
+```
+The base branch is `release`. [All releases (including
+betas)](https://github.com/XRPLF/rippled/blob/develop/CONTRIBUTING.md#before-you-start)
+go in `release`. This PR branch will be pushed directly to `release` (not
+squashed or rebased, and not using the GitHub UI).
+```
+
+7. Sign-offs for the three platforms (Linux, Mac, Windows) usually occur
+   offline, but at least one approval will be needed on the PR.
+   - If issues are discovered during testing, simply abandon the
+     release. It's easy to start a new release, it should be easy to
+     abandon one. **DO NOT REUSE THE VERSION NUMBER.** e.g. If you
+     abandon 2.4.0-b1, the next attempt will be 2.4.0-b2.
+8. Once everything is ready to go, push to `release`.
+
+```
+git fetch upstreams
+
+# Just to be safe, do a dry run first:
+git push --dry-run upstream-push release-next:release
+
+# If everything looks right, push the branch
+git push upstream-push release-next:release
+
+# Check that all of the branches are updated
+git fetch upstreams
+git log -1 --oneline
+# The output should look like:
+# 0123456789 (HEAD -> upstream/release-next, upstream/release,
+#            upstream/develop) Set version to 2.4.0-b1
+# Note that upstream/develop may not be on this commit, but
+# upstream/release must be.
+# Other branches, including some from upstream-push, may also be
+# present.
+```
+
+9. Tag the release, too.
+
+```
+git tag <version number>
+git push upstream-push <version number>
+```
+
+10. Delete the `release-next` branch on the repo. Use the Github UI or:
+
+```
+git push --delete upstream-push release-next
+```
+
+11. Finally [create a new release on
+    Github](https://github.com/XRPLF/rippled/releases).
+
+#### Release candidates after the first
+
+Once the first release candidate is [merged into
+release](#making-the-release), then `release` and `develop` _are allowed
+to diverge_.
+
+If a bug or issue is discovered in a version that has a release
+candidate being tested, any fix and new version will need to be applied
+against `release`, then reverse-merged to `develop`. This helps keep git
+history as linear as possible.
+
+A `release-next` branch will be created from `release`, and any further
+work for that release must be based on `release-next`. Specifically,
+PRs must use `release-next` as the base, and those PRs will be merged
+directly to `release-next` when approved. Changes should be restricted
+to bug fixes, but other changes may be necessary from time to time.
+
+1. Open any PRs for the pending release using `release-next` as the base,
+   so they can be merged directly in to it. Unlike `develop`, though,
+   `release-next` can be thrown away and recreated if necessary.
+2. Once a new release candidate is ready, create a version commit as in
+   step 1 [above](#making-the-release) on `release-next`. You can use
+   the [update-version] script for this, too.
+3. Jump to step 8 ("Now create a Pull Request for `release-next` with
+   **`release`** as the base") from the process
+   [above](#making-the-release) to merge `release-next` into `release`.
+
+##### Follow up: reverse merge
+
+Once the RC is merged and tagged, it needs to be reverse merged into
+`develop` as soon as possible.
+
+1. Create a branch, based on `upstream/develop`.
+   The branch name is not important, but could include "mergeNNNrcN".
+   E.g. For release A.B.C-rcD, use `mergeABCrcD`.
+
+```
+git fetch upstreams
+
+git checkout --no-track -b mergeABCrcD upstream/develop
+```
+
+2. Merge `release` into your branch.
+
+```
+# I like the "--edit --log --verbose" parameters, but they are
+# not required.
+git merge upstream/release
+```
+
+3. `BuildInfo.cpp` will have a conflict with the version number.
+   Resolve it with the version from `develop` - the higher version.
+4. Push your branch to your repo (or `upstream` if you have permission),
+   and open a normal PR against `develop`. The "High level overview" can
+   simply indicate that this is a merge of the RC. The "Context" should
+   summarize the changes from the RC. Include the following text
+   prominently:
+
+```
+This PR must be merged manually using a push. Do not use the Github UI.
+```
+
+5. Depending on the complexity of the changes, and/or merge conflicts,
+   the PR may need a thorough review, or just a sign-off that the
+   merge was done correctly.
+6. If `develop` is updated before this PR is merged, do not merge
+   `develop` back into your branch. Instead rebase preserving merges,
+   or do the merge again. (See also the `rerere` git config setting.)
+
+```
+git rebase --rebase-merges upstream/develop
+# OR
+git reset --hard upstream/develop
+git merge upstream/release
+```
+
+7. When the PR is ready, push it to `develop`.
+
+```
+git fetch upstreams
+
+# Make sure the commits look right
+git log --show-signature "upstream/develop^..HEAD"
+
+git push upstream-push mergeABCrcD:develop
+
+git fetch upstreams
+```
+
+Development on `develop` can proceed as normal.
+
+#### Final releases
+
+A final release is any release that is not a beta or RC, such as 2.2.0.
+
+Only code that has already been tested and vetted across all three
+platforms should be included in a final release. Most of the time, that
+means that the commit immediately preceding the commit setting the
+version number will be an RC. Occasionally, there may be last-minute bug
+fixes included as well. If so, those bug fixes must have been tested
+internally as if they were RCs (at minimum, ensuring unit tests pass,
+and the app starts, syncs, and stops cleanly across all three
+platforms.)
+
+_If in doubt, make an RC first._
+
+The process for building a final release is very similar to [the process
+for building a beta](#making-the-release), except the code will be
+moving from `release` to `master` instead of from `develop` to
+`release`, and both branches will be pushed at the same time.
+
+1. Ensure there is no old `master-next` branch hanging around.
+   Then make a `master-next` branch that only changes the version
+   number. As above, or using the
+   [update-version] script.
+2. Create a Pull Request for `master-next` with **`master`** as
+   the base branch. Instead of the default template, reuse and update
+   the message from the previous final release. Include the following verbiage
+   somewhere in the description:
+
+```
+The base branch is `master`. This PR branch will be pushed directly to
+`release` and `master` (not squashed or rebased, and not using the
+GitHub UI).
+```
+
+7. Sign-offs for the three platforms (Linux, Mac, Windows) usually occur
+   offline, but at least one approval will be needed on the PR.
+   - If issues are discovered during testing, close the PR, delete
+     `master-next`, and move development back to `release`, [issuing
+     more RCs as necessary](#release-candidates-after-the-first)
+8. Once everything is ready to go, push to `release` and `master`.
+
+```
+git fetch upstreams
+
+# Just to be safe, do dry runs first:
+git push --dry-run upstream-push master-next:release
+git push --dry-run upstream-push master-next:master
+
+# If everything looks right, push the branch
+git push upstream-push master-next:release
+git push upstream-push master-next:master
+
+# Check that all of the branches are updated
+git fetch upstreams
+git log -1 --oneline
+# The output should look like:
+# 0123456789 (HEAD -> upstream/master-next, upstream/master,
+#            upstream/release) Set version to A.B.0
+# Note that both upstream/release and upstream/master must be on this
+# commit.
+# Other branches, including some from upstream-push, may also be
+# present.
+```
+
+9. Tag the release, too.
+
+```
+git tag <version number>
+git push upstream-push <version number>
+```
+
+10. Delete the `master-next` branch on the repo. Use the Github UI or:
+
+```
+git push --delete upstream-push master-next
+```
+
+11. [Create a new release on
+    Github](https://github.com/XRPLF/rippled/releases). Be sure that
+    "Set as the latest release" is checked.
+12. Open a PR to update the [API-CHANGELOG](API-CHANGELOG.md) and `API-VERSION-[n].md` with the changes for this release (if any are missing).
+13. Finally, [reverse merge the release into `develop`](#follow-up-reverse-merge).
+
+#### Special cases: point releases, hotfixes, etc.
+
+On occasion, a bug or issue is discovered in a version that already
+had a final release. Most of the time, development will have started
+on the next version, and will usually have changes in `develop`
+and often in `release`.
+
+Because git history is kept as linear as possible, any fix and new
+version will need to be applied against `master`.
+
+The process for building a hotfix release is very similar to [the
+process for building release candidates after the
+first](#release-candidates-after-the-first) and [for building a final
+release](#final-releases), except the changes will be done against
+`master` instead of `release`.
+
+If there is only a single issue for the hotfix, the work can be done in
+any branch. When it's ready to merge, jump to step 3 using your branch
+instead of `master-next`.
+
+1. Create a `master-next` branch from `master`.
+
+```
+git checkout --no-track -b master-next upstream/master
+git push upstream-push
+git fetch upstreams
+```
+
+2. Open any PRs for the pending hotfix using `master-next` as the base,
+   so they can be merged directly in to it. Unlike `develop`, though,
+   `master-next` can be thrown away and recreated if necessary.
+3. Once the hotfix is ready, create a version commit using the same
+   steps as above, or use the
+   [update-version] script.
+4. Create a Pull Request for `master-next` with **`master`** as
+   the base branch. Instead of the default template, reuse and update
+   the message from the previous final release. Include the following verbiage
+   somewhere in the description:
+
+```
+The base branch is `master`. This PR branch will be pushed directly to
+`master` (not squashed or rebased, and not using the GitHub UI).
+```
+
+7. Sign-offs for the three platforms (Linux, Mac, Windows) usually occur
+   offline, but at least one approval will be needed on the PR.
+   - If issues are discovered during testing, update `master-next` as
+     needed, but ensure that the changes are properly squashed, and the
+     version setting commit remains last
+8. Once everything is ready to go, push to `master` **only**.
+
+```
+git fetch upstreams
+
+# Just to be safe, do a dry run first:
+git push --dry-run upstream-push master-next:master
+
+# If everything looks right, push the branch
+git push upstream-push master-next:master
+
+# Check that all of the branches are updated
+git fetch upstreams
+git log -1 --oneline
+# The output should look like:
+# 0123456789 (HEAD -> upstream/master-next, upstream/master) Set version
+#            to 2.4.1
+# Note that upstream/master must be on this commit. upstream/release and
+# upstream/develop should not.
+# Other branches, including some from upstream-push, may also be
+# present.
+```
+
+9. Tag the release, too.
+
+```
+git tag <version number>
+git push upstream-push <version number>
+```
+
+9. Delete the `master-next` branch on the repo.
+
+```
+git push --delete upstream-push master-next
+```
+
+10. [Create a new release on
+    Github](https://github.com/XRPLF/rippled/releases). Be sure that
+    "Set as the latest release" is checked.
+
+Once the hotfix is released, it needs to be reverse merged into
+`develop` as soon as possible. It may also need to be merged into
+`release` if a release candidate is under development.
+
+1. Create a branch in your own repo, based on `upstream/develop`.
+   The branch name is not important, but could include "mergeNNN".
+   E.g. For release 2.2.3, use `merge223`.
+
+```
+git fetch upstreams
+
+git checkout --no-track -b merge223 upstream/develop
+```
+
+2. Merge master into your branch.
+
+```
+# I like the "--edit --log --verbose" parameters, but they are
+# not required.
+git merge upstream/master
+```
+
+3. `BuildInfo.cpp` will have a conflict with the version number.
+   Resolve it with the version from `develop` - the higher version.
+4. Push your branch to your repo, and open a normal PR against
+   `develop`. The "High level overview" can simply indicate that this
+   is a merge of the hotfix version. The "Context" should summarize
+   the changes from the hotfix. Include the following text
+   prominently:
+
+```
+This PR must be merged manually using a --ff-only merge. Do not use the Github UI.
+```
+
+5. Depending on the complexity of the hotfix, and/or merge conflicts,
+   the PR may need a thorough review, or just a sign-off that the
+   merge was done correctly.
+6. If `develop` is updated before this PR is merged, do not merge
+   `develop` back into your branch. Instead rebase preserving merges,
+   or do the merge again. (See also the `rerere` git config setting.)
+
+```
+git rebase --rebase-merges upstream/develop
+# OR
+git reset --hard upstream/develop
+git merge upstream/master
+```
+
+7. When the PR is ready, push it to `develop`.
+
+```
+git fetch upstreams
+
+# Make sure the commits look right
+git log --show-signature "upstream/develop..HEAD"
+
+git push upstream-push HEAD:develop
+```
+
+Development on `develop` can proceed as normal. It is recommended to
+create a beta (or RC) immediately to ensure that everything worked as
+expected.
+
+##### An even rarer scenario: A hotfix on an old release
+
+Historically, once a final release is tagged and packages are released,
+versions older than the latest final release are no longer supported.
+However, there is a possibility that a very high severity bug may occur
+in a non-amendment blocked version that is still being run by
+a significant fraction of users, which would necessitate a hotfix / point
+release to that version as well as any later versions.
+
+This scenario would follow the same basic procedure as above,
+except that _none_ of `develop`, `release`, or `master`
+would be touched during the release process.
+
+In this example, consider if version 2.1.1 needed to be patched.
+
+1. Create two branches in the main (`upstream`) repo.
+
+```
+git fetch upstreams
+
+# Create a base branch off the tag
+git checkout --no-track -b master-2.1.2 2.1.1
+git push upstream-push
+
+# Create a working branch
+git checkout --no-track -b master212-next master-2.1.2
+git push upstream-push
+
+git fetch upstreams
+```
+
+2. Work continues as above, except using `master-2.1.2`as
+   the base branch for any merging, packaging, etc.
+3. After the release is tagged and packages are built, you could
+   potentially delete both branches, e.g. `master-2.1.2` and
+   `master212-next`. However, it may be useful to keep `master-2.1.2`
+   around indefinitely for reference.
+4. Assuming that a hotfix is also released for the latest
+   version in parallel with this one, or if the issue is
+   already fixed in the latest version, do no do any
+   reverse merges. However, if it is not, it probably makes
+   sense to reverse merge `master-2.1.2` into `master`,
+   release a hotfix for _that_ version, then reverse merge
+   from `master` to `develop`. (Please don't do this unless absolutely
+   necessary.)

-# Branching and Release Management
-
-This document describes how we branch, release, and merge releases back into `develop`.
-It does not define version naming
-(e.g., what constitutes a major-minor, patch, or beta release).
-
-Examples use `X.Y` for a release line:
-`X` and `Y` are placeholders, while the trailing `x` is literal,
-e.g., `release/X.Y.x` is `release/3.4.x` for the `3.4` line.
-
-## Branches
-
-| Branch          | Purpose                                                                                   |
-| :-------------- | :---------------------------------------------------------------------------------------- |
-| `develop`       | Main development branch. Betas and the first RC of a major-minor release are tagged here. |
-| `staging/X.Y.x` | Where fixes for the `X.Y` line are developed and RCs are prepared.                        |
-| `release/X.Y.x` | The last public RC or release of the `X.Y` line.                                          |
-
-A release line is named `X.Y.x`
-because one branch serves every patch release of that line (`X.Y.0`, `X.Y.1`, `X.Y.2`, ...).
-The `/` groups branches hierarchically,
-so tools can filter them and protection rules can target `release/*` and `staging/*`.
-
-## Principles
-
-- **Releases are merged back into `develop`, never cherry-picked or rebased onto it.**
-  Cherry-picked and rebased commits get new hashes,
-  so Git can't tell that `develop` already has them.
-  Future merges then replay them and produce artificial conflicts,
-  and it's hard to verify that every fix actually reached `develop`.
-  Merging keeps a single history:
-  Git knows exactly which release commits `develop` contains,
-  and no fix is left behind.
-- **Branches only move forward.**
-  `develop`, `staging/X.Y.x`, and `release/X.Y.x` are never rewritten.
-- **Cherry-picking only goes from `develop` to a staging branch**,
-  for fixes that must get into a release after the code freeze
-  (see [Emergency Fixes From `develop`](#emergency-fixes-from-develop)).
-- **Security fixes are prepared privately and published with the release that contains them**,
-  so vulnerabilities are not disclosed prematurely.
-
-## Release Lifecycle
-
-This diagram shows a major-minor release and its first patch release.
-The staging and release branches are drawn as one line.

-### Betas, First RC & Branching
-
-> [!NOTE]
-> This phase applies only to a new major-minor release (e.g., `X.Y.0`).
-> Patch releases work on the existing branches of the line.
-
-1. **Betas:** All beta versions (e.g., `X.Y.0-b1`) are built and tagged directly on `develop`.
-2. **First RC:** We release the first RC (`X.Y.0-rc1`)
-   once everything that should be included in the release has been merged.
-3. **Branches:** `staging/X.Y.x` and `release/X.Y.x` are created from `develop`
-   at the commit tagged `X.Y.0-rc1`.
-   The first RC also kicks off the QE process.
-4. **Code freeze:** No new features or unrelated changes are pulled from `develop`
-   into `staging/X.Y.x` or `release/X.Y.x`.
-   Only critical stabilization fixes go into the line.
-5. **No large changes on `develop`:** Until `X.Y.0` is [merged back](#merging-back-into-develop),
-   large changes (e.g., big refactors, moving or renaming many files, mass reformatting)
-   are not merged into `develop`,
-   so that fixes on the line and the merge back don't run into conflicts.
-
-### Release Candidates
-
-1. Fixes are developed against `staging/X.Y.x`.
-2. When ready, a new RC is created on `staging/X.Y.x`,
-   and `release/X.Y.x` is fast-forwarded to it.
-
-RCs that contain unpublished security fixes are not published,
-and don't touch the public branches.
-
-RCs are not merged back into `develop`:
-`X.Y.0-rc1` is tagged on `develop` itself,
-and all later changes reach `develop` with the [final release](#final-release).
-
-### Final Release
-
-Security fixes become public as soon as they reach the public repo,
-so these steps happen only once the release is ready to be published,
-one right after the other.
-
-1. Unpublished security fixes, if any, are merged into `staging/X.Y.x`.
-2. `release/X.Y.x` is fast-forwarded to `staging/X.Y.x`,
-   and the release is tagged on it.
-3. The release is immediately [merged back into `develop`](#merging-back-into-develop).
-   For a major-minor release, this lifts the freeze on large changes in `develop`.
-
-### Merging Back Into `develop`
-
-The merge back is a regular PR into `develop`
-whose branch contains a real merge commit of the release tag:
-
-1. Create a branch from `develop`, run `git merge --no-ff <tag>`, and resolve any conflicts.
-2. Once the PR is approved, `develop` is fast-forwarded to the PR branch,
-   so the merge commit lands as it is.
-   Never squash or rebase it.
-   Never add it to the merge queue either: the queue squashes PRs, which would drop the merge commit.
-3. If `develop` moves while the PR is open, redo the merge on top of the new `develop`.
-
-After the merge, `git log develop..<tag>` must be empty.
-
-## Special Cases
-
-### Emergency Fixes From `develop`
-
-If a commit was merged to `develop`
-and needs to be included in a release after the code freeze:
-
-1. Create a PR that cherry-picks the commit onto `staging/X.Y.x`.
-2. Leave `develop` as it is, with no reverts.
-3. Follow the [release candidates](#release-candidates) process as usual.
-
-When the release is later merged back into `develop`,
-both sides already contain the same change,
-so the merge usually resolves it cleanly or with a trivial conflict.
-From Git's perspective, the cherry-picked commit then becomes part of `develop` too.
-
-### Several Supported Lines
-
-When a fix must ship in more than one supported line (e.g., `X.Y` and `X.(Y+1)`),
-the lines are merged upwards rather than cherry-picked between:
-
-1. The fix goes into the oldest line first.
-2. After that line's release,
-   its `release/X.Y.x` is merged into the staging branch of the next newer line,
-   and so on up to the newest line.
-3. The newest line is merged back into `develop` as usual.
-
-This way every newer line, and eventually `develop`, contains the history of the older lines.

-Check that Rust unit tests stay out of the coverage report.
-
-cargo-llvm-cov instruments the test code along with everything else, so a test
-module that is not excluded counts its own body as covered and inflates the
-reported number. Excluding it takes two attributes:
-
-  * every `#[cfg(test)]` module carries
-    `#[cfg_attr(coverage_nightly, coverage(off))]`;
-  * every crate root (lib.rs, main.rs) carries
-    `#![cfg_attr(coverage_nightly, feature(coverage_attribute))]`, which the
-    attribute above needs in order to compile.
-
-Both are inert outside the coverage job: cargo-llvm-cov defines
-`coverage_nightly` only when it runs on a nightly toolchain.
-
-The crate-root gate is checked even in a crate that has no tests yet, because
-that is what lets the first test module added later carry the attribute without
-a build failure. Missing it is a hard error, so it cannot go unnoticed; a
-missing `coverage(off)` fails open, which is why this check exists.
-
-Matching is on exact attribute text, which works because `cargo fmt` runs over
-the whole workspace in the hook ahead of this one: rustfmt puts every attribute
-on its own line and normalizes what is inside it, turning `#[cfg( test )]`
-and `#[cfg(test,)]` alike into `#[cfg(test)]`. So there is nothing here that
-parses Rust. The price is that a cfg this file does not spell out literally --
-`all(test, ...)`, `any(test, ...)`, `not(test)` -- is reported rather than
-classified, on the grounds that guessing at coverage semantics is how a check
-like this ends up quietly wrong.

 To compile everything from source, add `--build '*'` to the `conan install`
 command.
 
-### Why the nixpkgs revision is not part of the package ID
-
-A Conan package ID records the compiler and its major version, but nothing about
-the nixpkgs revision the toolchain came from — and `flake.lock` moves far more
-often than the toolchain meaningfully changes, so folding it in would rebuild
-every dependency on every bump for nothing.
-
-That is safe as long as no cached artifact resolves a `/nix/store` path at run
-time, because store paths change on every update and the old ones disappear with
-`nix-collect-garbage`. With the `clang` toolchain macOS CI and the dev shell use,
-they do not: it links against `/usr/lib/libc++` and `/usr/lib/libSystem`, and
-store paths reach the `.a` files only through debug info, which nothing resolves
-at link or run time.
-
-> [!WARNING]
-> This does not hold for `nix develop .#gcc` on macOS. There is no system
-> libstdc++, so GCC links its own from the store and every binary keeps a
-> `/nix/store` reference. That shell is fine for tooling, but it is not a build
-> configuration CI covers, and no dependency binaries are published for it.
-
-This is checked rather than assumed.
-[`bin/check-nix-store-refs.sh`](../../bin/check-nix-store-refs.sh) takes one file
-or directory and fails if a binary under it resolves a store path at run time.
-CI runs it over the build output and the Conan cache, and again in the upload job
-before anything is published. You can run it yourself:
-
-```bash
-bin/check-nix-store-refs.sh build
-bin/check-nix-store-refs.sh ~/.conan2-nix
-```
-
-It works on Linux too, but asserts something narrower there: the toolchain always
-writes the store into `PT_INTERP` and `RUNPATH`, and CI builds inside an image
-whose store is fixed for its lifetime, so that is fine. Only the binaries
-[`PatchNixBinary.cmake`](../../cmake/PatchNixBinary.cmake) retargets to the
-system loader have to be clean, and those are what CI checks:
-
-```bash
-bin/check-nix-store-refs.sh build/xrpld
-```
-
-### The libresolv stub
-
-This is not hypothetical: `xrpld` used to be caught by it. The c-ares package
-tells the linker to pass `-lresolv`, and nixpkgs keeps `libresolv` out of the
-macOS SDK and ships it as an ordinary store dylib — so every Nix-built `xrpld`
-recorded a `/nix/store/…-libresolv-93/lib/libresolv.9.dylib` load command and
-stopped running once that path was collected. Nothing in the link uses a single
-symbol from it.
-
-Both environments now put a stub on the linker search path
-(`libresolvSystemStub` in [`nix/darwin.nix`](../../nix/darwin.nix)): the
-same library with its install name set to `/usr/lib/libresolv.9.dylib`, which is
-exactly the load command the Apple Clang build records.
-
-Package IDs did not change, so Conan keeps serving anything built before the
-stub landed. If a binary fails to start with `Library not loaded: /nix/store/…`,

-## `wint_t` / `uint32_t` errors from the Nix libc++ headers
-
-A build that mixes the Nix toolchain with the system SDK fails in libc++ itself,
-with errors that look nothing like your code:
-
-```
-/nix/store/...-libcxx-.../include/c++/v1/cwchar:136:9: error: target of using declaration conflicts with declaration already in scope
-  136 | using ::wint_t _LIBCPP_USING_IF_EXISTS;

-...
-error: use of undeclared identifier 'UINT32_C'
-```
-
-The give-away is the second path: Nix's libc++ headers are being combined with
-the **Xcode Command Line Tools** SDK instead of the Nix one.
-
-### Why it happens
-
-`SDKROOT` and `DEVELOPER_DIR` are what point the toolchain at the Nix SDK, and
-they are not baked into the compiler — a dev shell gets them from the
-`apple-sdk` setup hook. CMake, finding neither, asks `xcrun`, which answers with
-the system SDK. Nix's `libc++` and Apple's headers then declare the same types
-twice.
-
-### Fix
-
-Run the build from inside the dev shell (`nix develop`), or from an environment
-that exports both variables. To confirm which SDK a configured build is using:
-
-```bash
-grep -o '\-isysroot [^ ]*' build/compile_commands.json | sort -u
-```
-
-It should print a `/nix/store/...-apple-sdk-*` path. If it prints
-`/Library/Developer/CommandLineTools/...`, re-configure from within the shell —
-CMake caches the sysroot, so an existing `build/` directory keeps the wrong one.
-
-## `Library not loaded: /nix/store/…` from a binary that used to work
-
-A binary stops starting after a `nix flake update`, or after
-`nix-collect-garbage` removes the paths the previous toolchain used:
-
-```
-dyld[57271]: Library not loaded: /nix/store/…-libresolv-93/lib/libresolv.9.dylib
-```
-
-[`bin/check-nix-store-refs.sh`](../../bin/check-nix-store-refs.sh) finds the same
-thing without having to run anything, and names the file:
-
-```
-$ bin/check-nix-store-refs.sh ~/.conan2-nix
-::error file=/Users/you/.conan2-nix/p/b/c-area24ded30c388c/p/bin/adig::references the Nix store at run time

-/Users/you/.conan2-nix: checked 135, skipped 2495, 1 with Nix store references.
-```
-
-Conan's cache folders are named after a truncated package name plus a hash, so
-ask Conan which package the offending one belongs to — pass the folder holding
-the hash, not the file itself:
-
-```
-$ conan cache ref ~/.conan2-nix/p/b/c-area24ded30c388c

-```
-
-### Why it happens
-
-The binary records a store path that no longer exists. Nothing we build should:
-see [Prebuilt packages](./nix.md#prebuilt-packages) for why, and
-`libresolvSystemStub` in [`nix/darwin.nix`](../../nix/darwin.nix) for the one
-dependency that needed help to comply.
-
-A Conan package ID does not encode the nixpkgs revision, so a package built
-before that stub existed stays in your local cache and keeps being reused. The
-dev shell is also what tends to produce one: it is a slightly _less_ isolated
-build environment than CI's, because `mkShell` puts every tool's headers and
-libraries on the compiler's search path — which is how c-ares found the Nix
-`libresolv` in the first place.
-
-### Fix
-
-Drop that package and let Conan refetch or rebuild it:

-```bash
-conan remove 'c-ares/*'

-## Install the xrpld package
-
-### With the APT package manager
-
-1.  Install utilities:
-
-    ```bash
-    sudo apt update -y
-    sudo apt install -y apt-transport-https ca-certificates curl gnupg
-    ```
-
-2.  Add the XRPL Foundation package-signing key to your list of trusted keys:
-
-    ```bash
-    sudo install -d -m 0755 /etc/apt/keyrings
-    sudo curl -fsS https://packages.xrplf.org/xrplf.asc -o /etc/apt/keyrings/xrplf.asc
-    ```
-
-3.  Check the fingerprint of the newly-added key:
-
-    ```bash
-    gpg --show-keys /etc/apt/keyrings/xrplf.asc
-    ```
-
-    The output should be:
-
-    ```text
-    pub   rsa4096 2026-08-18 [SC]
-          B655416741221F780FBCFBC9AA84D41A11D29FA9
-    uid                      XRPLF Packages <distribution@xrplf.org>
-    ```
-
-    In particular, make sure that the fingerprint matches.
-
-4.  Add the repository, using the channel you picked in [Release channels](#release-channels):
-
-    ```bash
-    echo "deb [signed-by=/etc/apt/keyrings/xrplf.asc] https://packages.xrplf.org/repository/deb-stable any main" | \
-        sudo tee /etc/apt/sources.list.d/xrplf.list
-    ```
-
-5.  Fetch the repository:
-
-    ```bash
-    sudo apt -y update
-    ```
-
-6.  Install the `xrpld` software package:
-
-    ```bash
-    sudo apt -y install xrpld
-    ```
-
-### With the DNF package manager
-
-1.  Add the XRPL Foundation package-signing key:
-
-    ```bash
-    sudo rpm --import https://packages.xrplf.org/xrplf.asc
-    ```
-
-2.  Add the repository, using the channel you picked in [Release channels](#release-channels):
-
-    ```bash
-    cat << 'REPOFILE' | sudo tee /etc/yum.repos.d/xrplf.repo
-    [xrplf-stable]
-    name=XRP Ledger Packages
-    enabled=1
-    baseurl=https://packages.xrplf.org/repository/rpm-stable/$basearch/
-    gpgcheck=1
-    repo_gpgcheck=1
-    gpgkey=https://packages.xrplf.org/xrplf.asc
-    REPOFILE
-    ```
-
-    `gpgcheck=1` verifies each package against the key above.
-    `repo_gpgcheck=1` verifies the repository metadata, which the server signs with the same key.
-
-3.  Install the `xrpld` package:
-
-    ```bash
-    sudo dnf install -y xrpld
-    ```
-
-### Optional: the assert-enabled build
-
-Every channel also carries `xrpld-assert` as a DEB, the same build with assertions
-enabled, for diagnosing a problem on a non-production server.
-It installs the same files as `xrpld` and replaces it, so install one or the other:
-
-```bash
-sudo apt -y install xrpld-assert # APT removes xrpld itself
-```
-
-Switching stops the service, since it is a removal and an installation rather than an upgrade,
-and APT starts it again.
-Install `xrpld` the same way to switch back.
-
-## The xrpld service
-
-Both package managers install a systemd unit and enable it, so `xrpld` starts on boot.
-Check whether it is already running:
-
-```bash
-systemctl status xrpld.service
-```
-
-The DEB packages start it immediately as well; the RPM packages do not, so start it yourself:
-
-```bash
-sudo systemctl start xrpld.service
-```
-
-### Optional: binding to privileged ports
-
-To serve incoming API requests on port 80 or 443, grant the service the capability to bind them.
-You must also update the config file's port settings.
-
-```bash
-sudo install -d -m 0755 /etc/systemd/system/xrpld.service.d
-sudo tee /etc/systemd/system/xrpld.service.d/privileged-ports.conf >/dev/null <<'EOF'
-[Service]
-CapabilityBoundingSet=CAP_NET_BIND_SERVICE
-AmbientCapabilities=CAP_NET_BIND_SERVICE
-EOF
-sudo systemctl daemon-reload
-sudo systemctl restart xrpld.service
-```
