Track latencies of certain code blocks, and log if they take too long

Price Oracle data-series logic uses `unordered_map` to update the Oracle object.
This results in different servers disagreeing on the order of that hash table.
Consequently, the generated ledgers will have different hashes.
The fix uses `map` instead to guarantee the order of the token pairs
in the data-series.

 For a log of breaking changes, see the **API Version [number]** headings. In general, breaking changes are associated with a particular API Version number. For non-breaking changes, scroll to the **XRP Ledger version [x.y.z]** headings. Non-breaking changes are associated with a particular XRP Ledger (`rippled`) release.
 
-## API Version 2
-
-API version 2 is available in `rippled` version 2.0.0 and later. To use this API, clients specify `"api_version" : 2` in each request.
-
-#### Removed methods
-
-In API version 2, the following deprecated methods are no longer available: (https://github.com/XRPLF/rippled/pull/4759)
-
-- `tx_history` - Instead, use other methods such as `account_tx` or `ledger` with the `transactions` field set to `true`.
-- `ledger_header` - Instead, use the `ledger` method.
-
-#### Modifications to JSON transaction element in V2
-
-In API version 2, JSON elements for transaction output have been changed and made consistent for all methods which output transactions. (https://github.com/XRPLF/rippled/pull/4775)
-This helps to unify the JSON serialization format of transactions. (https://github.com/XRPLF/clio/issues/722, https://github.com/XRPLF/rippled/issues/4727)
-
-- JSON transaction element is named `tx_json`
-- Binary transaction element is named `tx_blob`
-- JSON transaction metadata element is named `meta`
-- Binary transaction metadata element is named `meta_blob`
-
-Additionally, these elements are now consistently available next to `tx_json` (i.e. sibling elements), where possible:
-
-- `hash` - Transaction ID. This data was stored inside transaction output in API version 1, but in API version 2 is a sibling element.
-- `ledger_index` - Ledger index (only set on validated ledgers)
-- `ledger_hash` - Ledger hash (only set on closed or validated ledgers)
-- `close_time_iso` - Ledger close time expressed in ISO 8601 time format (only set on validated ledgers)
-- `validated` - Bool element set to `true` if the transaction is in a validated ledger, otherwise `false`
-
-This change affects the following methods:
-
-- `tx` - Transaction data moved into element `tx_json` (was inline inside `result`) or, if binary output was requested, moved from `tx` to `tx_blob`. Renamed binary transaction metadata element (if it was requested) from `meta` to `meta_blob`. Changed location of `hash` and added new elements
-- `account_tx` - Renamed transaction element from `tx` to `tx_json`. Renamed binary transaction metadata element (if it was requested) from `meta` to `meta_blob`. Changed location of `hash` and added new elements
-- `transaction_entry` - Renamed transaction metadata element from `metadata` to `meta`. Changed location of `hash` and added new elements
-- `subscribe` - Renamed transaction element from `transaction` to `tx_json`. Changed location of `hash` and added new elements
-- `sign`, `sign_for`, `submit` and `submit_multisigned` - Changed location of `hash` element.
-
-#### Modification to `Payment` transaction JSON schema
-
-When reading Payments, the `Amount` field should generally **not** be used. Instead, use [delivered_amount](https://xrpl.org/partial-payments.html#the-delivered_amount-field) to see the amount that the Payment delivered. To clarify its meaning, the `Amount` field is being renamed to `DeliverMax`. (https://github.com/XRPLF/rippled/pull/4733)
-
-- In `Payment` transaction type, JSON RPC field `Amount` is renamed to `DeliverMax`. To enable smooth client transition, `Amount` is still handled, as described below: (https://github.com/XRPLF/rippled/pull/4733)
-  - On JSON RPC input (e.g. `submit_multisigned` etc. methods), `Amount` is recognized as an alias to `DeliverMax` for both API version 1 and version 2 clients.
-  - On JSON RPC input, submitting both `Amount` and `DeliverMax` fields is allowed _only_ if they are identical; otherwise such input is rejected with `rpcINVALID_PARAMS` error.
-  - On JSON RPC output (e.g. `subscribe`, `account_tx` etc. methods), `DeliverMax` is present in both API version 1 and version 2.
-  - On JSON RPC output, `Amount` is only present in API version 1 and _not_ in version 2.
-
-#### Modifications to account_info response
-
-- `signer_lists` is returned in the root of the response. (In API version 1, it was nested under `account_data`.) (https://github.com/XRPLF/rippled/pull/3770)
-- When using an invalid `signer_lists` value, the API now returns an "invalidParams" error. (https://github.com/XRPLF/rippled/pull/4585)
-  - (`signer_lists` must be a boolean. In API version 1, strings were accepted and may return a normal response - i.e. as if `signer_lists` were `true`.)
-
-#### Modifications to [account_tx](https://xrpl.org/account_tx.html#account_tx) response
-
-- Using `ledger_index_min`, `ledger_index_max`, and `ledger_index` returns `invalidParams` because if you use `ledger_index_min` or `ledger_index_max`, then it does not make sense to also specify `ledger_index`. In API version 1, no error was returned. (https://github.com/XRPLF/rippled/pull/4571)
-  - The same applies for `ledger_index_min`, `ledger_index_max`, and `ledger_hash`. (https://github.com/XRPLF/rippled/issues/4545#issuecomment-1565065579)
-- Using a `ledger_index_min` or `ledger_index_max` beyond the range of ledgers that the server has:
-  - returns `lgrIdxMalformed` in API version 2. Previously, in API version 1, no error was returned. (https://github.com/XRPLF/rippled/issues/4288)
-- Attempting to use a non-boolean value (such as a string) for the `binary` or `forward` parameters returns `invalidParams` (`rpcINVALID_PARAMS`). Previously, in API version 1, no error was returned. (https://github.com/XRPLF/rippled/pull/4620)
-
-#### Modifications to [noripple_check](https://xrpl.org/noripple_check.html#noripple_check) response
-
-- Attempting to use a non-boolean value (such as a string) for the `transactions` parameter returns `invalidParams` (`rpcINVALID_PARAMS`). Previously, in API version 1, no error was returned. (https://github.com/XRPLF/rippled/pull/4620)
-
 ## API Version 1
 
-This version is supported by all `rippled` versions. For WebSocket and HTTP JSON-RPC requests, it is currently the default API version used when no `api_version` is specified.
+This version is supported by all `rippled` versions. At time of writing, it is the default API version, used when no `api_version` is specified. When a new API version is introduced, the command line interface will default to the latest API version. The command line is intended for ad-hoc usage by humans, not programs or automated scripts. The command line is not meant for use in production code.
 
-The [commandline](https://xrpl.org/docs/references/http-websocket-apis/api-conventions/request-formatting/#commandline-format) always uses the latest API version. The command line is intended for ad-hoc usage by humans, not programs or automated scripts. The command line is not meant for use in production code.
+### Idiosyncrasies
 
-### Inconsistency: server_info - network_id
+#### V1 account_info response
 
-The `network_id` field was added in the `server_info` response in version 1.5.0 (2019), but it is not returned in [reporting mode](https://xrpl.org/rippled-server-modes.html#reporting-mode). However, use of reporting mode is now discouraged, in favor of using [Clio](https://github.com/XRPLF/clio) instead.
+In [the response to the `account_info` command](https://xrpl.org/account_info.html#response-format), there is `account_data` - which is supposed to be an `AccountRoot` object - and `signer_lists` is returned in this object. However, the docs say that `signer_lists` should be at the root level of the reponse.

+It makes sense for `signer_lists` to be at the root level because signer lists are not part of the AccountRoot object. (First reported in [xrpl-dev-portal#938](https://github.com/XRPLF/xrpl-dev-portal/issues/938).)
 
-As of 2025-01-28, version 2.4.0 is in development. You can use a pre-release version by building from source or [using the `nightly` package](https://xrpl.org/docs/infrastructure/installation/install-rippled-on-ubuntu).
+In `api_version: 2`, the `signer_lists` field [will be moved](#modifications-to-account_info-response-in-v2) to the root level of the account_info response. (https://github.com/XRPLF/rippled/pull/3770)
 
-### Additions and bugfixes in 2.4.0
+#### server_info - network_id
 
-- `ledger_entry`: `state` is added an alias for `ripple_state`.
-- `ledger_entry`: Enables case-insensitive filtering by canonical name in addition to case-sensitive filtering by RPC name.
-- `validators`: Added new field `validator_list_threshold` in response.
-- `simulate`: A new RPC that executes a [dry run of a transaction submission](https://github.com/XRPLF/XRPL-Standards/tree/master/XLS-0069d-simulate#2-rpc-simulate)
-- Signing methods autofill fees better and properly handle transactions that don't have a base fee, and will also autofill the `NetworkID` field.

-[Version 2.3.0](https://github.com/XRPLF/rippled/releases/tag/2.3.0) was released on Nov 25, 2024.
-
-### Breaking changes in 2.3.0
-
-- `book_changes`: If the requested ledger version is not available on this node, a `ledgerNotFound` error is returned and the node does not attempt to acquire the ledger from the p2p network (as with other non-admin RPCs).
-
-Admins can still attempt to retrieve old ledgers with the `ledger_request` RPC.

 - `server_definitions`: A new RPC that generates a `definitions.json`-like output that can be used in XRPL libraries.
 - In `Payment` transactions, `DeliverMax` has been added. This is a replacement for the `Amount` field, which should not be used. Typically, the `delivered_amount` (in transaction metadata) should be used. To ease the transition, `DeliverMax` is present regardless of API version, since adding a field is non-breaking.
 - API version 2 has been moved from beta to supported, meaning that it is generally available (regardless of the `beta_rpc_api` setting).

   removed from the [ledger subscription stream](https://xrpl.org/subscribe.html#ledger-stream), because it will no longer
   have any meaning.
 
+## API Version 2
+
+API version 2 is introduced in `rippled` version 2.0. Users can request it explicitly by specifying `"api_version" : 2`.
+
+#### Removed methods
+
+In API version 2, the following deprecated methods are no longer available: (https://github.com/XRPLF/rippled/pull/4759)
+
+- `tx_history` - Instead, use other methods such as `account_tx` or `ledger` with the `transactions` field set to `true`.
+- `ledger_header` - Instead, use the `ledger` method.
+
+#### Modifications to JSON transaction element in V2
+
+In API version 2, JSON elements for transaction output have been changed and made consistent for all methods which output transactions. (https://github.com/XRPLF/rippled/pull/4775)
+This helps to unify the JSON serialization format of transactions. (https://github.com/XRPLF/clio/issues/722, https://github.com/XRPLF/rippled/issues/4727)
+
+- JSON transaction element is named `tx_json`
+- Binary transaction element is named `tx_blob`
+- JSON transaction metadata element is named `meta`
+- Binary transaction metadata element is named `meta_blob`
+
+Additionally, these elements are now consistently available next to `tx_json` (i.e. sibling elements), where possible:
+
+- `hash` - Transaction ID. This data was stored inside transaction output in API version 1, but in API version 2 is a sibling element.
+- `ledger_index` - Ledger index (only set on validated ledgers)
+- `ledger_hash` - Ledger hash (only set on closed or validated ledgers)
+- `close_time_iso` - Ledger close time expressed in ISO 8601 time format (only set on validated ledgers)
+- `validated` - Bool element set to `true` if the transaction is in a validated ledger, otherwise `false`
+
+This change affects the following methods:
+
+- `tx` - Transaction data moved into element `tx_json` (was inline inside `result`) or, if binary output was requested, moved from `tx` to `tx_blob`. Renamed binary transaction metadata element (if it was requested) from `meta` to `meta_blob`. Changed location of `hash` and added new elements
+- `account_tx` - Renamed transaction element from `tx` to `tx_json`. Renamed binary transaction metadata element (if it was requested) from `meta` to `meta_blob`. Changed location of `hash` and added new elements
+- `transaction_entry` - Renamed transaction metadata element from `metadata` to `meta`. Changed location of `hash` and added new elements
+- `subscribe` - Renamed transaction element from `transaction` to `tx_json`. Changed location of `hash` and added new elements
+- `sign`, `sign_for`, `submit` and `submit_multisigned` - Changed location of `hash` element.
+
+#### Modification to `Payment` transaction JSON schema
+
+When reading Payments, the `Amount` field should generally **not** be used. Instead, use [delivered_amount](https://xrpl.org/partial-payments.html#the-delivered_amount-field) to see the amount that the Payment delivered. To clarify its meaning, the `Amount` field is being renamed to `DeliverMax`. (https://github.com/XRPLF/rippled/pull/4733)
+
+- In `Payment` transaction type, JSON RPC field `Amount` is renamed to `DeliverMax`. To enable smooth client transition, `Amount` is still handled, as described below: (https://github.com/XRPLF/rippled/pull/4733)
+  - On JSON RPC input (e.g. `submit_multisigned` etc. methods), `Amount` is recognized as an alias to `DeliverMax` for both API version 1 and version 2 clients.
+  - On JSON RPC input, submitting both `Amount` and `DeliverMax` fields is allowed _only_ if they are identical; otherwise such input is rejected with `rpcINVALID_PARAMS` error.
+  - On JSON RPC output (e.g. `subscribe`, `account_tx` etc. methods), `DeliverMax` is present in both API version 1 and version 2.
+  - On JSON RPC output, `Amount` is only present in API version 1 and _not_ in version 2.
+
+#### Modifications to account_info response
+
+- `signer_lists` is returned in the root of the response. In API version 1, it was nested under `account_data`. (https://github.com/XRPLF/rippled/pull/3770)
+- When using an invalid `signer_lists` value, the API now returns an "invalidParams" error. (https://github.com/XRPLF/rippled/pull/4585)
+  - (`signer_lists` must be a boolean. In API version 1, strings were accepted and may return a normal response - i.e. as if `signer_lists` were `true`.)
+
+#### Modifications to [account_tx](https://xrpl.org/account_tx.html#account_tx) response
+
+- Using `ledger_index_min`, `ledger_index_max`, and `ledger_index` returns `invalidParams` because if you use `ledger_index_min` or `ledger_index_max`, then it does not make sense to also specify `ledger_index`. In API version 1, no error was returned. (https://github.com/XRPLF/rippled/pull/4571)
+  - The same applies for `ledger_index_min`, `ledger_index_max`, and `ledger_hash`. (https://github.com/XRPLF/rippled/issues/4545#issuecomment-1565065579)
+- Using a `ledger_index_min` or `ledger_index_max` beyond the range of ledgers that the server has:
+  - returns `lgrIdxMalformed` in API version 2. Previously, in API version 1, no error was returned. (https://github.com/XRPLF/rippled/issues/4288)
+- Attempting to use a non-boolean value (such as a string) for the `binary` or `forward` parameters returns `invalidParams` (`rpcINVALID_PARAMS`). Previously, in API version 1, no error was returned. (https://github.com/XRPLF/rippled/pull/4620)

@@ -71,248 +71,27 @@ The source must be formatted according to the style guide below.
 
 Header includes must be [levelized](./Builds/levelization).
 
-Changes should be usually squashed down into a single commit.
-Some larger or more complicated change sets make more sense,
-and are easier to review if organized into multiple logical commits.
-Either way, all commits should fit the following criteria:
-* Changes should be presented in a single commit or a logical
-  sequence of commits.
-  Specifically, chronological commits that simply
-  reflect the history of how the author implemented
-  the change, "warts and all", are not useful to
-  reviewers.
-* Every commit should have a [good message](#good-commit-messages).
-  to explain a specific aspects of the change.
-* Every commit should be signed.
-* Every commit should be well-formed (builds successfully,
-  unit tests passing), as this helps to resolve merge
-  conflicts, and makes it easier to use `git bisect`
-  to find bugs.
-
-### Good commit messages
-
-Refer to
-["How to Write a Git Commit Message"](https://cbea.ms/git-commit/)
-for general rules on writing a good commit message.
-
-tl;dr
-> 1. Separate subject from body with a blank line.
-> 2. Limit the subject line to 50 characters.
->    * [...]shoot for 50 characters, but consider 72 the hard limit.
-> 3. Capitalize the subject line.
-> 4. Do not end the subject line with a period.
-> 5. Use the imperative mood in the subject line.
->    * A properly formed Git commit subject line should always be able
->      to complete the following sentence: "If applied, this commit will
->      _your subject line here_".
-> 6. Wrap the body at 72 characters.
-> 7. Use the body to explain what and why vs. how.
-
-In addition to those guidelines, please add one of the following
-prefixes to the subject line if appropriate.
-* `fix:` - The primary purpose is to fix an existing bug.
-* `perf:` - The primary purpose is performance improvements.
-* `refactor:` - The changes refactor code without affecting
-  functionality.
-* `test:` - The changes _only_ affect unit tests.
-* `docs:` - The changes _only_ affect documentation. This can
-  include code comments in addition to `.md` files like this one.
-* `build:` - The changes _only_ affect the build process,
-  including CMake and/or Conan settings.
-* `chore:` - Other tasks that don't affect the binary, but don't fit
-  any of the other cases. e.g. formatting, git settings, updating
-  Github Actions jobs.
-
-Whenever possible, when updating commits after the PR is open, please
-add the PR number to the end of the subject line. e.g. `test: Add
-unit tests for Feature X (#1234)`.
 
 ## Pull requests
 
 In general, pull requests use `develop` as the base branch.
+
 (Hotfixes are an exception.)
 
-If your changes are not quite ready, but you want to make it easily available
-for preliminary examination or review, you can create a "Draft" pull request.
-While a pull request is marked as a "Draft", you can rebase or reorganize the
-commits in the pull request as desired.
-
-Github pull requests are created as "Ready" by default, or you can mark
-a "Draft" pull request as "Ready".
-Once a pull request is marked as "Ready",
-any changes must be added as new commits. Do not
-force-push to a branch in a pull request under review.
-(This includes rebasing your branch onto the updated base branch.
-Use a merge operation, instead or hit the "Update branch" button
-at the bottom of the Github PR page.)
+Changes to pull requests must be added as new commits.
+Once code reviewers have started looking at your code, please avoid
+force-pushing a branch in a pull request.
 This preserves the ability for reviewers to filter changes since their last
 review.
 
-A pull request must obtain **approvals from at least two reviewers**
-before it can be considered for merge by a Maintainer.
+A pull request must obtain **approvals from at least two reviewers** before it
+can be considered for merge by a Maintainer.
 Maintainers retain discretion to require more approvals if they feel the
 credibility of the existing approvals is insufficient.
 
 Pull requests must be merged by [squash-and-merge][2]
 to preserve a linear history for the `develop` branch.
 
-### When and how to merge pull requests
-
-#### "Passed"
-
-A pull request should only have the "Passed" label added when it
-meets a few criteria:
-
-1. It must have two approving reviews [as described
-   above](#pull-requests). (Exception: PRs that are deemed "trivial"
-   only need one approval.)
-2. All CI checks must be complete and passed. (One-off failures may
-   be acceptable if they are related to a known issue.)
-3. The PR must have a [good commit message](#good-commit-messages).
-   * If the PR started with a good commit message, and it doesn't
-     need to be updated, the author can indicate that in a comment.
-   * Any contributor, preferably the author, can leave a comment
-     suggesting a commit message.
-   * If the author squashes and rebases the code in preparation for
-     merge, they should also ensure the commit message(s) are updated
-     as well.
-4. The PR branch must be up to date with the base branch (usually
-   `develop`). This is usually accomplised by merging the base branch
-   into the feature branch, but if the other criteria are met, the
-   changes can be squashed and rebased on top of the base branch.
-5. Finally, and most importantly, the author of the PR must
-   positively indicate that the PR is ready to merge. That can be
-   accomplished by adding the "Passed" label if their role allows,
-   or by leaving a comment to the effect that the PR is ready to
-   merge.
-
-Once the "Passed" label is added, a maintainer may merge the PR at
-any time, so don't use it lightly.
-
-#### Instructions for maintainers
-
-The maintainer should double-check that the PR has met all the
-necessary criteria, and can request additional information from the
-owner, or additional reviews, and can always feel free to remove the
-"Passed" label if appropriate. The maintainer has final say on
-whether a PR gets merged, and are encouraged to communicate and
-issues or concerns to other maintainers.
-
-##### Most pull requests: "Squash and merge"
-
-Most pull requests don't need special handling, and can simply be
-merged using the "Squash and merge" button on the Github UI. Update
-the suggested commit message if necessary.
-
-##### Slightly more complicated pull requests
-
-Some pull requests need to be pushed to `develop` as more than one
-commit. There are multiple ways to accomplish this. If the author
-describes a process, and it is reasonable, follow it. Otherwise, do
-a fast forward only merge (`--ff-only`) on the command line and push.
-
-Either way, check that:
-* The commits are based on the current tip of `develop`.
-* The commits are clean: No merge commits (except when reverse
-  merging), no "[FOLD]" or "fixup!" messages.
-* All commits are signed. If the commits are not signed by the author, use
-  `git commit --amend -S` to sign them yourself.
-* At least one (but preferably all) of the commits has the PR number
-  in the commit message.
-
-**Never use the "Create a merge commit" or "Rebase and merge"
- functions!**
-
-##### Releases, release candidates, and betas
-
-All releases, including release candidates and betas, are handled
-differently from typical PRs. Most importantly, never use
-the Github UI to merge a release.
-
-1. There are two possible conditions that the `develop` branch will
-   be in when preparing a release.
-   1. Ready or almost ready to go: There may be one or two PRs that
-      need to be merged, but otherwise, the only change needed is to
-      update the version number in `BuildInfo.cpp`. In this case,
-      merge those PRs as appropriate, updating the second one, and
-      waiting for CI to finish in between. Then update
-      `BuildInfo.cpp`.
-   2. Several pending PRs: In this case, do not use the Github UI,
-      because the delays waiting for CI in between each merge will be
-      unnecessarily onerous. Instead, create a working branch (e.g.
-      `develop-next`) based off of `develop`. Squash the changes
-      from each PR onto the branch, 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. The workflow may
-      look something like:
-```
-git fetch upstream
-git checkout upstream/develop
-git checkout -b develop-next
-# Use -S on the ff-only merge if prbranch1 isn't signed.
-# Or do another branch first.
-git merge --ff-only user1/prbranch1
-git merge --squash user2/prbranch2
-git commit -S
-git merge --squash user3/prbranch3
-git commit -S
-[...]
-git push --set-upstream origin develop-next
-</pre>
-```
-2. Create the Pull Request with `release` as the base branch. If any
-   of the included PRs are still open,
-   [use closing keywords](https://docs.github.com/articles/closing-issues-using-keywords)
-   in the description to ensure they are closed when the code is
-   released. e.g. "Closes #1234"
-3. 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) go in
-release. This PR will be merged with --ff-only (not squashed or
-rebased, and not using the GitHub UI) to both release and develop.
-```
-4. Sign-offs for the three platforms usually occur offline, but at
-   least one approval will be needed on the PR.
-5. Once everything is ready to go, open a terminal, and do the
-   fast-forward merges manually. Do not push any branches until you
-   verify that all of them update correctly.
-```
-git fetch upstream
-git checkout -b upstream--develop -t upstream/develop || git checkout upstream--develop
-git reset --hard upstream/develop
-# develop-next must be signed already!
-git merge --ff-only origin/develop-next
-git checkout -b upstream--release -t upstream/release || git checkout upstream--release
-git reset --hard upstream/release
-git merge --ff-only origin/develop-next
-# Only do these 3 steps if pushing a release. No betas or RCs
-git checkout -b upstream--master -t upstream/master || git checkout upstream--master
-git reset --hard upstream/master
-git merge --ff-only origin/develop-next
-# Check that all of the branches are updated
-git log -1 --oneline
-# The output should look like:
-# 02ec8b7962 (HEAD -> upstream--master, origin/develop-next, upstream--release, upstream--develop, develop-next) Set version to 2.2.0-rc1
-# Note that all of the upstream--develop/release/master are on this commit.
-# (Master will be missing for betas, etc.)
-# Just to be safe, do a dry run first:
-git push --dry-run upstream-push HEAD:develop
-git push --dry-run upstream-push HEAD:release
-# git push --dry-run upstream-push HEAD:master
-# Now push
-git push upstream-push HEAD:develop
-git push upstream-push HEAD:release
-# git push upstream-push HEAD:master
-# Don't forget to tag the release, too.
-git tag <version number>
-git push upstream-push <version number>
-```
-6. Finally
-[create a new release on Github](https://github.com/XRPLF/rippled/releases).

-## Contracts and instrumentation
-
-We are using [Antithesis](https://antithesis.com/) for continuous fuzzing,
-and keep a copy of [Antithesis C++ SDK](https://github.com/antithesishq/antithesis-sdk-cpp/)
-in `external/antithesis-sdk`. One of the aims of fuzzing is to identify bugs
-by finding external conditions which cause contracts violations inside `rippled`.
-The contracts are expressed as `XRPL_ASSERT` or `UNREACHABLE` (defined in
-`include/xrpl/beast/utility/instrumentation.h`), which are effectively (outside
-of Antithesis) wrappers for `assert(...)` with added name. The purpose of name
-is to provide contracts with stable identity which does not rely on line numbers.
-
-When `rippled` is built with the Antithesis instrumentation enabled
-(using `voidstar` CMake option) and ran on the Antithesis platform, the
-contracts become
-[test properties](https://antithesis.com/docs/using_antithesis/properties.html);
-otherwise they are just like a regular `assert`.
-To learn more about Antithesis, see
-[How Antithesis Works](https://antithesis.com/docs/introduction/how_antithesis_works.html)
-and [C++ SDK](https://antithesis.com/docs/using_antithesis/sdk/cpp/overview.html#)
-
-We continue to use the old style `assert` or `assert(false)` in certain
-locations, where the reporting of contract violations on the Antithesis
-platform is either not possible or not useful.
-
-For this reason:
-* The locations where `assert` or `assert(false)` contracts should continue to be used:
-  * `constexpr` functions
-  * unit tests i.e. files under `src/test`
-  * unit tests-related modules (files under `beast/test` and `beast/unit_test`)
-* Outside of the listed locations, do not use `assert`; use `XRPL_ASSERT` instead,
-  giving it unique name, with the short description of the contract.
-* Outside of the listed locations, do not use `assert(false)`; use
-  `UNREACHABLE` instead, giving it unique name, with the description of the
-  condition being violated
-* The contract name should start with a full name (including scope) of the
-  function, optionally a named lambda, followed by a colon ` : ` and a brief
-  (typically at most five words) description. `UNREACHABLE` contracts
-  can use slightly longer descriptions. If there are multiple overloads of the
-  function, use common sense to balance both brevity and unambiguity of the
-  function name. NOTE: the purpose of name is to provide stable means of
-  unique identification of every contract; for this reason try to avoid elements
-  which can change in some obvious refactors or when reinforcing the condition.
-* Contract description typically (except for `UNREACHABLE`) should describe the
-  _expected_ condition, as in "I assert that _expected_ is true".
-* Contract description for `UNREACHABLE` should describe the _unexpected_
-  situation which caused the line to have been reached.
-* Example good name for an
-  `UNREACHABLE` macro `"Json::operator==(Value, Value) : invalid type"`; example
-  good name for an `XRPL_ASSERT` macro `"Json::Value::asCString : valid type"`.
-* Example **bad** name
-  `"RFC1751::insert(char* s, int x, int start, int length) : length is greater than or equal zero"`
-  (missing namespace, unnecessary full function signature, description too verbose).
-  Good name: `"ripple::RFC1751::insert : minimum length"`.
-* In **few** well-justified cases a non-standard name can be used, in which case a
-  comment should be placed to explain the rationale (example in `contract.cpp`)
-* Do **not** rename a contract without a good reason (e.g. the name no longer
-  reflects the location or the condition being checked)
-* Do not use `std::unreachable`
-* Do not put contracts where they can be violated by an external condition
-  (e.g. timing, data payload before mandatory validation etc.) as this creates
-  bogus bug reports (and causes crashes of Debug builds)
