-# OTel naming-consistency check
-
-`check_otel_naming.py` enforces the OpenTelemetry span-attribute naming
-convention documented in
-[CONTRIBUTING.md](../../../CONTRIBUTING.md#telemetry-span-attribute-naming)
-across every layer of the telemetry pipeline. The `*SpanNames.h` constants are
-the single source of truth (L1); every other layer must agree with them.
-
-## Running locally
-
-```
-python .github/scripts/otel-naming/check_otel_naming.py
-```
-
-It takes no arguments, can be run from any directory inside the repo, and uses
-only the Python standard library (no `pip install`, matching the levelization
-check). A non-zero exit code means a violation was found; the output lists each
-violation as `RULE | location | token | expected`.
-
-## What it checks
-
-The valid key set is **derived dynamically from the OTel code** — there is no
-hardcoded allowlist:
-
-- **L1 keys** come from the `namespace attr { ... }` blocks of every
-  `*SpanNames.h`, resolving the `makeStr("x")` / `join(seg::a, seg::b)` DSL
-  (cross-file, so `join(seg::rpc, ...)` resolves `seg::rpc` from the base
-  `SpanNames.h`). Each constant is resolved against **its own** header, so two
-  headers that define a same-named constant (e.g. a base `attr::ledgerHash` and
-  a domain `attr::ledgerHash`) each contribute their real wire key — a later
-  header cannot clobber an earlier one's value in a flat table.
-- **Legitimate dotted keys** = ONLY the keys the code actually sets as resource
-  attributes, i.e. the entries inside `Telemetry.cpp`'s `Resource::Create({...})`
-  call: the `semconv::service::*` keys (`service.*`) plus any `attr::<name>`
-  constants passed there (`xrpl.network.*`). A dotted key that is _declared_ in a
-  header but never set as a resource attr is a span attribute in resource
-  clothing — a Rule-A violation, even if it lives in the base `SpanNames.h`.
-
-### Rules (each fails the build, when its inputs are present)

-| G    | Attribute keys are `lower_snake_case` (`^[a-z][a-z0-9_]*$` per dot-segment) — no camelCase, UPPERCASE, or spaces.                                                                                                                                                                        |
-| F    | No string literals as attribute keys or span-name arguments in `setAttribute`/`addEvent`/`span`/`rootSpan`/`childSpan` (`rootSpan` shares `span`'s `(cat, prefix, name)` signature). Attribute _values_ are exempt (runtime data); `*SpanNames.h` definitions and test files are exempt. |
-| B    | Every collector `spanmetrics.dimensions` name exists in the L1 key set.                                                                                                                                                                                                                  |
-| C    | Every Tempo span-filter tag exists in the L1 key set.                                                                                                                                                                                                                                    |
-| D    | Every dashboard label resolves to an L1 span attribute, a native-metric label (L6, emitted by MetricsRegistry), or a Prometheus/Grafana builtin. TraceQL scope prefixes (`span.`/`resource.`/…) are stripped before the L1 lookup.                                                       |
-| E    | No dotted `xrpl.<domain>.<field>` attribute key in the runbook (only the L1 resource attrs `xrpl.network.*` may be dotted). Span names, filenames, OTel-standard keys, and metric labels are not flagged.                                                                                |
-
-Rule F runs **unconditionally** (it is a purely syntactic check on the
-call-sites and needs no `*SpanNames.h`), so a code path that calls
-`SpanGuard::span`/`setAttribute` directly without ever defining a header is
-still caught.

-Usage: check_otel_naming.py
-This script takes no parameters and can be called from any directory inside the
-repository (it locates the repo root via `git rev-parse`).
-
-Enforces the OpenTelemetry span-attribute naming convention documented in
-CONTRIBUTING.md ("Telemetry span attribute naming") across every layer of the
-telemetry pipeline. The `*SpanNames.h` constants are the single source of truth
-(L1); every other layer must agree with them.
-
-Design principles
------------------
-1. No hardcoded allowlist. The set of valid attribute keys — including which
-   dotted keys are legitimate resource attributes — is derived dynamically by
-   parsing the repository's own OTel code:
-     * `*SpanNames.h` `namespace attr { ... }` blocks (the underscore/bare keys
-       and the `join(seg::..., ...)` dotted resource compositions), and
-     * the keys the code passes to `Resource::Create({ ... })` in Telemetry.cpp
-       (the standard `semconv::service::*` keys -> service.name/version/...).
-   The one narrow, explicit exception is EXTERNAL_INFRA_LABELS (Rule D):
-   identity labels stamped by infrastructure outside this repo's OTel code
-   (the perf-iac harness), which by definition have no source in-tree to
-   derive from. Kept separate from the generic Prometheus/Grafana builtins
-   set so the exception stays visible rather than blending into "things
-   every OTel setup has".
-
-2. Presence-gated enforcement. Every rule runs ONLY when the source files it
-   needs are present in the tree, and is otherwise skipped (never failed). This
-   keeps the check correct no matter how work is split across PRs: a stacked
-   chain, one large PR, or independent per-stage PRs where (for example) the
-   collector config lands in a different PR than the dashboards. The check never
-   assumes a file from another phase/PR exists.

-  L1 resource  : src/libxrpl/telemetry/Telemetry.cpp           (dotted allowlist)

-
-Rules (each FAILS the build, when its inputs are present)
----------------------------------------------------------
-  A  No stray dotted span-attribute key. A dotted `<a>.<b>` used as a span
-     attribute that is not in the derived resource-key set is a violation.
-  G  Attribute keys must be lower_snake_case (^[a-z][a-z0-9_]*$ per segment).
-     Flags camelCase, UPPERCASE, spaces, and other stray characters.
-  F  No string literals as attribute keys or span-name arguments. The
-     setAttribute/addEvent key and the span/rootSpan/childSpan prefix/name args
-     must reference a *SpanNames.h constant, never a "literal". Attribute VALUES
-     are exempt (runtime data). Definitions inside *SpanNames.h are exempt, and
-     test files are exempt (they pass arbitrary literals to exercise the API).
-  B  Every collector spanmetrics dimension exists in the L1 key set.
-  C  Every tempo span-filter tag exists in the L1 key set.
-  D  Every dashboard label resolves to an L1 span attribute, an L6
-     native-metric label, or a builtin. TraceQL `span.`/`resource.` scope
-     prefixes are stripped before the L1 lookup.
-  E  No dotted `xrpl.<domain>.<field>` attribute key in the runbook (only the
-     L1 resource attrs xrpl.network.* may be dotted). Span names, filenames,
-     OTel-standard keys, and metric labels are not flagged.
-
-Warnings (printed, but do NOT fail the build)
-----------------------------------------------
-  H  A constant referenced at a telemetry call-site is not defined in any
-     *SpanNames.h. Span constants should live in the corresponding
-     *SpanNames.h (single source of truth); defining one in-place bypasses the
-     naming rules. A warning (not a failure) because the argument may instead
-     be a legitimately dynamic local (e.g. a computed span-name leaf).
-
-Exit code is non-zero if any present-and-enforced rule finds a violation.
-Warnings never change the exit code.

-# AGENTS.md

-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). Commit messages: see [CONTRIBUTING.md](./CONTRIBUTING.md#good-commit-messages).

-## 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).

-## 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
-
-[Version 3.3.0](https://github.com/XRPLF/rippled/releases/tag/3.3.0) was released on Aug 6, 2026.
-
-### 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.

-[Version 3.2.0](https://github.com/XRPLF/rippled/releases/tag/3.2.0) was released on Jun 16, 2026.
-
-### Additions in 3.2.0
-
-- `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.
-  - `LEDGER_ENTRY_FORMATS`: Describes the fields and their optionality for each ledger entry type, including common fields shared across all ledger entries.
-  - `TRANSACTION_FLAGS`: Maps transaction type names to their supported flags and flag values.
-  - `LEDGER_ENTRY_FLAGS`: Maps ledger entry type names to their flags and flag values.
-  - `ACCOUNT_SET_FLAGS`: Maps AccountSet flag names (asf flags) to their numeric values.
-
-### Bugfixes in 3.2.0
-
-- 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)
-- `account_info`: The `urlgravatar` field now uses HTTPS instead of HTTP. [#6529](https://github.com/XRPLF/rippled/pull/6529)
-- `ledger`: The `full`, `accounts`, `transactions`, `expand`, `binary`, `owner_funds`, and `queue` fields now return an error if the value is not a boolean. [#6529](https://github.com/XRPLF/rippled/pull/6529)
-- `ledger_data`: The `binary` field now returns an error if the value is not a boolean. [#6529](https://github.com/XRPLF/rippled/pull/6529)
-- `submit`: The `fail_hard` field now returns an error if the value is not a boolean. [#6529](https://github.com/XRPLF/rippled/pull/6529)
-- `subscribe`: The `taker` field in the `books` array now returns `actMalformed` instead of `badIssuer` if the value is not a valid account. [#6529](https://github.com/XRPLF/rippled/pull/6529)
-- Fixed a bug in `Forwarded` HTTP header parsing where the extracted IP address could be incorrect when no comma or semicolon delimiter follows the address. This could cause the server to misidentify a client's IP address when operating behind a reverse proxy. [#6529](https://github.com/XRPLF/rippled/pull/6529)

+
+#### Default profile
+
+We recommend that you import the provided `conan/profiles/default` profile:
 
 ```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).
+#### Custom profile
+
+If the default profile does not work for you and you do not yet have a Conan
+profile, you can create one by running:
+
+```bash
+conan profile detect
+```
+
+You may need to make changes to the profile to suit your environment. You can
+refer to the provided `conan/profiles/default` profile for inspiration, and you
+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.
+recipes=('ed25519' 'grpc' 'nudb' 'openssl' 'secp256k1' 'snappy' 'soci')
+folders=('all'     'all'  'all'  '3.x.x'   'all'       'all'    'all')
+
+# Selectively check out the recipes from our CCI fork.
+cd external
+mkdir -p conan-center-index
+cd conan-center-index
+git init
+git remote add origin git@github.com:XRPLF/conan-center-index.git
+git sparse-checkout init
+for ((index = 1; index <= ${#recipes[@]}; index++)); do
+  recipe=${recipes[index]}
+  folder=${folders[index]}
+  echo "Checking out recipe '${recipe}' from folder '${folder}'..."
+  git sparse-checkout add recipes/${recipe}/${folder}
+done
+git fetch origin master
+git checkout master
+cd ../..
+
+# Export the recipes into the local cache.
+for ((index = 1; index <= ${#recipes[@]}; index++)); do
+  recipe=${recipes[index]}
+  folder=${folders[index]}
+  version=$(extract_version ${recipe})
+  echo "Exporting '${recipe}/${version}' from '${recipe}/${folder}'..."
+  conan export --version $(extract_version ${recipe}) \
+    external/conan-center-index/recipes/${recipe}/${folder}
+done
+```
+
+In the case we switch to a newer version of a dependency that still requires a
+patch, it will be necessary for you to pull in the changes and re-export the
+updated dependencies with the newer version. However, if we switch to a newer
+version that no longer requires a patch, no action is required on your part, as
+the new recipe will be automatically pulled from the official Conan Center.
+
+> [!NOTE]
+> You might need to add `--lockfile=""` to your `conan install` command
+> to avoid automatic use of the existing `conan.lock` file when you run
+> `conan export` manually on your machine
+
+### Conan profile tweaks
+
+#### Missing compiler version
+
+If you see an error similar to the following after running `conan profile show`:
+
+```bash
+ERROR: Invalid setting '17' is not a valid 'settings.compiler.version' value.
+Possible values are ['5.0', '5.1', '6.0', '6.1', '7.0', '7.3', '8.0', '8.1',
+'9.0', '9.1', '10.0', '11.0', '12.0', '13', '13.0', '13.1', '14', '14.0', '15',
+'15.0', '16', '16.0']
+Read "http://docs.conan.io/2/knowledge/faq.html#error-invalid-setting"
+```
+
+you need to amend the list of compiler versions in
+`$(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:
+
+```text
+In file included from .../lib/promise/try_seq.h:26:
+.../lib/promise/detail/basic_seq.h:499:38: error: a template argument list is expected after a name prefixed by the template keyword [-Wmissing-template-arg-list-after-template-kw]
+  499 |                     Traits::template CallSeqFactory(f_, *cur_, std::move(arg)));
+      |                                      ^
+```
+
+The workaround for this error is to add two lines to profile:
+
+```text
+[conf]
+tools.build:cxxflags=['-Wno-missing-template-arg-list-after-template-kw']
+```
+
+#### Workaround for gcc 12
+
+If your compiler is gcc, version 12, and you have enabled `werr` option, you may
+encounter a compilation error such as:
+
+```text

+```
+
+The workaround for this error is to add two lines to your profile:
+
+```text

+tools.build:cxxflags=['-Wno-restrict']
+```
+
+#### Workaround for clang 16
+
+If your compiler is clang, version 16, you may encounter compilation error such
+as:
+
+```text

+[Unity builds][5] 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.
 
-### 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`):
-
-```bash
-cargo test --manifest-path crates/Cargo.toml --workspace
-```
-
-### 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.

-runs each tool configured in
-[`.pre-commit-config.yaml`](./.pre-commit-config.yaml) in its own isolated

-`clang-tidy` and `cargo fmt` — run tools from your own environment; see
-[Installing clang-tidy](#installing-clang-tidy) and
-[Rust](./docs/build/environment.md#rust) 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
-- `cargo fmt` — Rust formatting for the crates in `crates/`
-- `prettier`, `black`, `shfmt` — formatting for JavaScript/JSON/Markdown, Python, and shell
-- `cspell` — spell checking

-## Clang-tidy
-
-All code must pass `clang-tidy` checks according to the settings in [`.clang-tidy`](./.clang-tidy).
-
-There is a Continuous Integration job that runs clang-tidy on pull requests. The CI will check:
-
-- All changed C++ files (`.cpp`, `.h`, `.ipp`) when only code files are modified
-- **All files in the repository** when the `.clang-tidy` configuration file is changed
-
-This ensures that configuration changes don't introduce new warnings across the codebase.
-
-### 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 generate the files it depends on (protobuf headers, and, when the project is configured with `-Drust=ON`, the cxxbridge headers from the Rust crates). Configure the project as described in [`BUILD.md`](./BUILD.md), then build the `tidy_prerequisites` target, which generates all of them:
-
-```bash
-cmake --build build --target tidy_prerequisites
-```
-
-#### 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:
+You can install a pre-commit hook to automatically run `clang-format` before every commit:
 
 ```
-TIDY=1 pre-commit run clang-tidy
+pip3 install pre-commit
+pre-commit install
 ```
 
-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 -allow-no-checks src tests
-```
-
-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.

-## Telemetry span attribute naming
-
-OpenTelemetry span attribute keys follow these rules so they stay consistent
-across the code, the OTel collector, Tempo, Grafana dashboards, and docs. The
-constants in the `*SpanNames.h` headers are the single source of truth; every
-other layer must match them. A CI check enforces this end to end.
-
-1. Per-span unique attribute: bare field name — allowed when the field is
-   recorded by a single span/workflow, so the span name already supplies the
-   domain (e.g. `command`, `local`, `version` on `rpc.command` / `tx.process`).
-2. Shared attribute (same concept on more than one span): ONE key, reused
-   verbatim on every span that records it — the span name tells the occurrences
-   apart, so no per-emitter prefix is added. Pick the name by the field's
-   meaning: a property of a domain object keeps that object's bare field name
-   (`ledger_hash`, `ledger_seq`, `tx_hash`, `peer_id`, `full_validation`); a
-   field already qualified by a sub-kind keeps that qualifier on every emitter
-   (`proposal_trusted` on both `consensus.proposal.receive` and
-   `peer.proposal.receive`; `validation_trusted` likewise). Define it once in
-   the base `SpanNames.h` `namespace attr` block and re-export (`using`) it from
-   each domain header, so all emitters share the exact string.
-3. Collision qualifier: `<domain>_<field>` — only when a bare name would collide
-   with a DIFFERENT concept in the shared spanmetrics label space, or with the
-   OTel-reserved `status` key (e.g. `rpc_status`, `grpc_status`,
-   `consensus_phase`, `consensus_round`). This disambiguates distinct concepts
-   that share a word; it is NOT used to tag the same concept with the workflow
-   that emitted it — that is rule 2 (one shared name).
-4. Resource attribute: dotted `xrpl.<subsystem>.<field>` — reserved ONLY for
-   process/network identity set once at startup (`xrpl.network.id`,
-   `xrpl.network.type`). Never use the dotted `xrpl.` form for span attributes.
-5. Span names use `<subsystem>[.<component>]` (dotted). Only attribute _keys_
-   follow rules 1–4.
-
-All attribute keys are `lower_snake_case` (lowercase letters, digits, and
-underscores; each dot-separated segment of a resource key likewise). No
-camelCase, uppercase, or spaces.
-
-Standard OpenTelemetry semantic-convention keys keep their canonical dotted
-form (e.g. `service.*` resource attributes, `http.*` span attributes); the
-"no dotted form" rule above applies to xrpl-custom keys, not to OTel-standard
-conventions.
-
-Always reference the `*SpanNames.h` constants for attribute keys and span
-names — never pass a string literal as a key or as a `span`/`childSpan` name
-argument. (Attribute _values_ may be runtime data.)
-
-These rules are enforced by `.github/scripts/otel-naming/check_otel_naming.py`,
-run in CI on every pull request. The check derives the set of valid keys
-directly from the `*SpanNames.h` constants and the resource attributes the code
-registers, so there is no separate list to keep in sync. It cross-validates the
-collector, Tempo, dashboards, and docs against those keys, and each rule runs
-only when the file it needs is present — so it works whether telemetry changes
-land in one pull request or several. Run it locally with:
-
-```
-python .github/scripts/otel-naming/check_otel_naming.py
-```
-
-See [.github/scripts/otel-naming/README.md](.github/scripts/otel-naming/README.md)
-for the full rule list.

-## What is Distributed Tracing?
-
-Distributed tracing is a method for tracking data objects as they flow through distributed systems. In a network like XRP Ledger, a single transaction touches multiple independent nodes—each with no shared memory or logging. Distributed tracing connects these dots.
-
-**Without tracing:** You see isolated logs on each node with no way to correlate them.
-
-**With tracing:** You see the complete journey of a transaction or an event across all nodes it touched.

-
-## Core Concepts
-
-### 1. Trace
-
-A **trace** represents the entire journey of a request through the system. It has a unique `trace_id` that stays constant across all nodes.
-
-```
-Trace ID: abc123
-├── Node A: received transaction
-├── Node B: relayed transaction
-├── Node C: included in consensus
-└── Node D: applied to ledger
-```
-
-### 2. Span
-
-A **span** represents a single unit of work within a trace. Each span has:
-
-| Attribute        | Description                      | Example                    |
-| ---------------- | -------------------------------- | -------------------------- |
-| `trace_id`       | Identifies the trace             | `event123`                 |
-| `span_id`        | Unique identifier                | `span456`                  |
-| `parent_span_id` | Parent span (if any)             | `p_span123`                |
-| `name`           | Operation name                   | `rpc.submit`               |
-| `start_time`     | When work began (local time)     | `2024-01-15T10:30:00Z`     |
-| `end_time`       | When work completed (local time) | `2024-01-15T10:30:00.050Z` |
-| `attributes`     | Key-value metadata               | `tx_hash=ABC...`           |
-| `status`         | OK, ERROR MSG                    | `OK`                       |
-
-### 3. Trace Context
-
-**Trace context** is the data that propagates between services to link spans together. It contains:
-
-- `trace_id` - The trace this span belongs to
-- `span_id` - The current span (becomes parent for child spans)
-- `trace_flags` - Sampling decisions
-

-
-## How Spans Form a Trace
-
-Spans have parent-child relationships forming a tree structure:
-
-```mermaid
-flowchart TB
-    subgraph trace["Trace: abc123"]
-        A["tx.submit<br/>span_id: 001<br/>50ms"] --> B["tx.validate<br/>span_id: 002<br/>5ms"]

-        A --> D["tx.apply<br/>span_id: 004<br/>30ms"]
-        D --> E["ledger.update<br/>span_id: 005<br/>20ms"]
-    end
-
-    style A fill:#0d47a1,stroke:#082f6a,color:#ffffff
-    style B fill:#1b5e20,stroke:#0d3d14,color:#ffffff
-    style C fill:#1b5e20,stroke:#0d3d14,color:#ffffff
-    style D fill:#1b5e20,stroke:#0d3d14,color:#ffffff
-    style E fill:#bf360c,stroke:#8c2809,color:#ffffff
-```
-
-**Reading the diagram:**
-
-- **tx.submit (blue, root)**: The top-level span representing the entire transaction submission; all other spans are its descendants.
-- **tx.validate, tx.relay, tx.apply (green)**: Direct children of tx.submit, representing the three main stages -- validation, relay to peers, and application to the ledger.
-- **ledger.update (red)**: A grandchild span nested under tx.apply, representing the actual ledger state mutation triggered by applying the transaction.
-- **Arrows (parent to child)**: Each arrow indicates a parent-child span relationship where the parent's completion depends on the child finishing.

-
-## Span Relationships
-
-Spans don't always form simple parent-child trees. Distributed tracing defines several relationship types to capture different causal patterns:
-
-### 1. Parent-Child (ChildOf)
-
-The default relationship. The parent span **depends on** or **contains** the child span. The child runs within the scope of the parent.
-
-```
-tx.submit (parent)
-├── tx.validate (child)     ← parent waits for this
-├── tx.relay (child)        ← parent waits for this
-└── tx.apply (child)        ← parent waits for this
-```
-
-**When to use:** Synchronous calls, nested operations, any case where the parent's completion depends on the child.
-
-### 2. Follows-From
-
-A causal relationship where the first span **triggers** the second, but does **not wait** for it. The originator fires and moves on.
-
-```
-Time →
-
-tx.receive [=======]
-                     ↓ triggers (follows-from)
-              tx.relay   [===========]   ← runs independently
-```
-
-**When to use:** Asynchronous jobs, queued work, fire-and-forget patterns. For example, a node receives a transaction and queues it for relay — the relay span _follows from_ the receive span but the receiver doesn't wait for relaying to complete.
-
-> **OpenTracing** defined `FollowsFrom` as a first-class reference type alongside `ChildOf`.
-> **OpenTelemetry** represents this using **Span Links** with descriptive attributes instead (see below).
-
-### 3. Span Links (Cross-Trace and Non-Hierarchical)
-
-Links connect spans that are **causally related but not in a parent-child hierarchy**. Unlike parent-child, links can cross trace boundaries.
-
-```
-Trace A                          Trace B
-──────                           ──────
-batch.schedule                   batch.execute
-├─ item.enqueue (span X)    ┌──► process.item
-├─ item.enqueue (span Y) ───┤    (links to X, Y, Z)
-├─ item.enqueue (span Z)    └──►
-```
-
-**Use cases:**
-
-| Pattern              | Description                                                                 |
-| -------------------- | --------------------------------------------------------------------------- |
-| **Batch processing** | A batch span links back to all individual spans that contributed to it      |
-| **Fan-in**           | An aggregation span links to the multiple producer spans it merges          |
-| **Fan-out**          | Multiple downstream spans link back to the single span that triggered them  |
-| **Async handoff**    | A deferred job links back to the request that queued it (follows-from)      |
-| **Cross-trace**      | Correlating spans across independent traces (e.g., retries, related events) |
-
-**Link structure:** Each link carries the target span's context plus optional attributes:
-
-```
-Link {
-    trace_id:   <target trace>
-    span_id:    <target span>
-    attributes: { "link.description": "triggered by batch scheduler" }
-}
-```

-## Trace ID Generation
-
-A `trace_id` is a 128-bit (16-byte) identifier that groups all spans belonging to one logical operation. How it's generated determines how easily you can find and correlate traces later.
-
-### General Approaches
-
-#### 1. Random (W3C Default)
-
-Generate a random 128-bit ID when a trace starts. Standard approach for most services.
-
-```
-trace_id = random_128_bits()
-```
-
-| Pros                        | Cons                                          |
-| --------------------------- | --------------------------------------------- |
-| Simple, standard            | No natural correlation to domain events       |
-| Guaranteed unique per trace | If propagation is lost, trace is broken       |
-| Works with all OTel tooling | "Find trace for TX abc" requires index lookup |
-
-#### 2. Deterministic (Derived from Domain Data)
-
-Compute the trace_id from a hash of a natural identifier. Every node independently derives the **same** trace_id for the same event.
-
-```
-trace_id = SHA-256(domain_identifier)[0:16]   // truncate to 128 bits
-```
-
-| Pros                                                | Cons                                                       |
-| --------------------------------------------------- | ---------------------------------------------------------- |
-| Propagation-resilient — same ID computed everywhere | Same event processed twice (retry) shares trace_id         |
-| Natural search — domain ID maps directly to trace   | Non-standard (tooling assumes random)                      |
-| No coordination needed between nodes                | 256→128 bit truncation (collision risk negligible at ~2⁶⁴) |
-
-#### 3. Hybrid (Deterministic Prefix + Random Suffix)
-
-First 8 bytes derived from domain data, last 8 bytes random.
-
-```
-trace_id = SHA-256(domain_identifier)[0:8] || random_64_bits()
-```
-
-| Pros                                        | Cons                                     |
-| ------------------------------------------- | ---------------------------------------- |
-| Prefix search: "find all traces for TX abc" | Must propagate to maintain full trace_id |
-| Unique per processing instance              | More complex generation logic            |
-| Retries get distinct trace_ids              | Partial correlation only (prefix match)  |
-
-### XRPL Workflow Analysis
-
-XRPL has a unique advantage: its core workflows produce **globally unique 256-bit hashes** that are known on every node. This makes deterministic trace_id generation practical in ways most systems can't achieve.
-
-#### Natural Identifiers by Workflow
-
-| Workflow            | Natural Identifier                | Size       | Known at Start?               | Same on All Nodes?               |
-| ------------------- | --------------------------------- | ---------- | ----------------------------- | -------------------------------- |
-| **Transaction**     | Transaction hash (`tid_`)         | 256-bit    | Yes — computed before signing | Yes — hash of canonical tx data  |
-| **Consensus round** | Previous ledger hash + ledger seq | 256+32 bit | Yes — known when round opens  | Yes — all validators agree       |
-| **Validation**      | Ledger hash being validated       | 256-bit    | Yes — from consensus result   | Yes — same closed ledger         |
-| **Ledger catch-up** | Target ledger hash                | 256-bit    | Yes — we know what to fetch   | Yes — identifies ledger globally |
-
-#### Where These Identifiers Live in Code
-
-```
-Transaction:     STTx::getTransactionID()     → uint256 tid_
-                 TMTransaction::rawTransaction → recompute hash from bytes
-
-Consensus:       ConsensusProposal::previousLedger_ → uint256 (previous ledger hash)
-                 ConsensusProposal::position_       → uint256 (TxSet hash)
-                 LedgerHeader::seq                  → uint32_t (ledger sequence)
-
-Validation:      STValidation::getLedgerHash()  → uint256
-                 STValidation::getNodeID()      → NodeID (160-bit)
-
-Ledger fetch:    InboundLedger constructor      → uint256 hash, uint32_t seq
-                 TMGetLedger::ledgerHash        → bytes (uint256)
-```
-
-### Recommended Strategy: Workflow-Scoped Deterministic
-
-Each workflow type derives its trace_id from its natural domain identifier:
-
-```
-Transaction trace:   trace_id = SHA-256("tx"    || tx_hash)[0:16]
-Consensus trace:     trace_id = SHA-256("cons"  || prev_ledger_hash || ledger_seq)[0:16]
-Ledger catch-up:     trace_id = SHA-256("fetch" || target_ledger_hash)[0:16]
-```
-
-The string prefix (`"tx"`, `"cons"`, `"fetch"`) prevents collisions between workflows that might share underlying hashes.
-
-**Why this works for XRPL:**
-
-1. **Propagation-resilient** — Even if a P2P message drops trace context, every node independently computes the same trace_id from the same tx_hash or ledger_hash. Spans still correlate.
-
-2. **Zero-cost search** — "Show me the trace for transaction ABC" becomes a direct lookup: compute `SHA-256("tx" || ABC)[0:16]` and query. No secondary index needed.
-
-3. **Cross-workflow linking via Span Links** — A consensus trace links to individual transaction traces. A validation span links to the consensus trace. This connects the full picture without forcing everything into one giant trace.
-
-### Cross-Workflow Correlation
-
-Each workflow gets its own trace. Span Links tie them together:

-**Reading the diagram:**
-
-- **Transaction Trace (blue)**: An independent trace whose `trace_id` is deterministically derived from the transaction hash. Contains receive, validate, and relay spans.
-- **Consensus Trace (green)**: An independent trace whose `trace_id` is derived from the previous ledger hash and sequence number. Covers the open, propose, and accept phases.
-- **Validation (red)**: Validation spans live within the consensus trace (not a separate trace). They are created after the accept phase completes.
-- **Catch-Up Trace (purple)**: An independent trace for ledger acquisition, derived from the target ledger hash. Used when a node is behind and fetching missing ledgers.
-- **Dotted arrows (span links)**: Cross-trace correlations. Consensus links to transaction traces it included; catch-up links to the consensus trace that produced the target ledger.
-- **Solid arrow (C3 to V1)**: A parent-child relationship -- validation spans are direct children of the consensus accept span within the same trace.
-
-**How a query flows:**
-
-```
-"Why was TX abc slow?"
-  1. Compute trace_id = SHA-256("tx" || abc)[0:16]
-  2. Find transaction trace → see it was included in consensus round N
-  3. Follow span link → consensus trace for round N
-  4. See which phase was slow (propose? accept?)
-  5. If a node was catching up, follow link → catch-up trace
-```
-
-### Trade-offs to Consider
-
-| Concern                       | Mitigation                                                                                                                    |
-| ----------------------------- | ----------------------------------------------------------------------------------------------------------------------------- |
-| **Retries get same trace_id** | Add `attempt` attribute to root span; spans have unique span_ids and timestamps                                               |
-| **256→128 bit truncation**    | Birthday-bound collision at ~2⁶⁴ operations — negligible for XRPL's throughput                                                |
-| **Non-standard generation**   | OTel spec allows any 16-byte non-zero value; tooling works on the hex string                                                  |
-| **Hash computation cost**     | SHA-256 is ~0.3μs per call; XRPL already computes these hashes for other purposes                                             |
-| **Late-binding identifiers**  | Ledger hash isn't known until after consensus — validation spans use ledger_seq as fallback, then link to the consensus trace |

-**Reading the diagram:**
-
-- **Client**: The external entity that submits a transaction. It does not carry trace context -- the trace originates at the first node.
-- **Node A**: The entry point that creates a new trace (trace_id: abc123) and the root span `tx.receive`. It relays the transaction to peers with trace context attached.
-- **Node B and Node C**: Peer nodes that receive the relayed transaction along with the propagated trace context. Each creates a child span under Node A's span, preserving the same `trace_id`.
-- **Arrows with trace context**: The relay messages carry `trace_id` and `parent_span_id`, allowing each downstream node to link its spans back to the originating span on Node A.

-## Context Propagation
-
-For traces to work across nodes, **trace context must be propagated** in messages.
-
-### What's in the Context (~26 bytes)
-
-| Field         | Size     | Description                                             |
-| ------------- | -------- | ------------------------------------------------------- |
-| `trace_id`    | 16 bytes | Identifies the entire trace (constant across all nodes) |
-| `span_id`     | 8 bytes  | The sender's current span (becomes parent on receiver)  |
-| `trace_flags` | 1 byte   | Sampling decision (bit 0 = sampled; bits 1-7 reserved)  |
-| `trace_state` | variable | Optional vendor-specific data (typically omitted)       |
-
-### How span_id Changes at Each Hop
-
-Only **one** `span_id` travels in the context - the sender's current span. Each node:
-
-1. Extracts the received `span_id` and uses it as the `parent_span_id`
-2. Creates a **new** `span_id` for its own span
-3. Sends its own `span_id` as the parent when forwarding
-
-```
-Node A                      Node B                      Node C
-──────                      ──────                      ──────
-
-Span AAA                    Span BBB                    Span CCC
-   │                           │                           │
-   ▼                           ▼                           ▼
-Context out:                Context out:                Context out:
-├─ trace_id: abc123         ├─ trace_id: abc123         ├─ trace_id: abc123
-├─ span_id: AAA ──────────► ├─ span_id: BBB ──────────► ├─ span_id: CCC ──────►
-└─ flags: 01                └─ flags: 01                └─ flags: 01
-                               │                           │
-                          parent = AAA               parent = BBB
-```
-
-The `trace_id` stays constant, but `span_id` **changes at every hop** to maintain the parent-child chain.
-
-### Propagation Formats
-
-There are two patterns:
-
-### HTTP/RPC Headers (W3C Trace Context)
-
-```
-traceparent: 00-4bf92f3577b34da6a3ce929d0e0e4736-00f067aa0ba902b7-01
-             │  │                                │                │
-             │  │                                │                └── Flags (sampled)
-             │  │                                └── Parent span ID (16 hex)
-             │  └── Trace ID (32 hex)
-             └── Version
-```
-
-### Protocol Buffers (xrpld P2P messages)
-
-xrpld P2P messages such as `TMTransaction` carry the trace context in two added byte fields alongside the existing payload: `trace_parent` holds the W3C traceparent (`trace_id`, `span_id`, and `trace_flags`), and `trace_state` holds the optional W3C tracestate. Together they propagate the trace across the P2P boundary so a receiving node can attach its spans to the sender's span.
-
----
-
-## Sampling
-
-Not every trace needs to be recorded. **Sampling** reduces overhead:
-
-### Head Sampling (at trace start)
-
-```
-Request arrives → Random N% chance → Record or skip entire trace
-```
-
-- ✅ Low overhead
-- ❌ May miss interesting traces
-
-> **xrpld note**: xrpld intentionally fixes head sampling at 100% (sample
-> everything) and does not expose a configurable ratio. A per-node ratio
-> would let different nodes make divergent keep/drop decisions for the same
-> distributed trace, producing broken/partial traces. xrpld uses a
-> `ParentBased` sampler so spans with a remote parent honor the upstream
-> decision. Volume reduction is delegated to collector-side tail sampling.
-
-### Tail Sampling (after trace completes)
-
-```
-Trace completes → Collector evaluates:
-                  - Error? → KEEP
-                  - Slow? → KEEP
-                  - Normal? → Sample 10%
-```
-
-- ✅ Never loses important traces
-- ❌ Higher memory usage at collector
-

-- **Processing Layer (green)**: Core business logic -- NetworkOPs processes transactions, LedgerMaster manages ledger state, NodeStore handles persistence, and InboundLedgers synchronizes missing data.
-- **Application Services (purple)**: Higher-level features -- PathFinding computes payment routes, TxQ manages fee-based queuing, and LoadManager tracks server load.
-- **Existing Observability (orange)**: The current monitoring stack (PerfLog, Insight, Journal logging) that OpenTelemetry will complement, not replace.
-- **Arrows (Services to JobQueue to layers)**: Work originates at Core Services, is enqueued onto the JobQueue, and dispatched to Processing or Application layers for execution.

-## 1.3 Transaction Flow Diagram
-
-Transaction flow spans multiple nodes in the network. Each node creates linked spans to form a distributed trace:
-
-```mermaid
-sequenceDiagram
-    participant Client
-    participant PeerA as Peer A (Receive)
-    participant PeerB as Peer B (Relay)
-    participant PeerC as Peer C (Validate)
-
-    Client->>PeerA: 1. Submit TX
-
-    rect rgb(230, 245, 255)
-        Note over PeerA: tx.receive SPAN START
-        PeerA->>PeerA: HashRouter Deduplication
-        PeerA->>PeerA: tx.validate (child span)
-    end
-
-    PeerA->>PeerB: 2. Relay TX (with trace ctx)
-
-    rect rgb(230, 245, 255)
-        Note over PeerB: tx.receive (linked span)
-    end
-
-    PeerB->>PeerC: 3. Relay TX
-
-    rect rgb(230, 245, 255)
-        Note over PeerC: tx.receive (linked span)
-        PeerC->>PeerC: tx.process
-    end
-
-    Note over Client,PeerC: DISTRIBUTED TRACE (same trace_id: abc123)
-```
-
-**Reading the diagram:**
-
-- **Client**: The external entity that submits a transaction to Peer A. It has no trace context -- the trace starts at the first node.
-- **Peer A (Receive)**: The entry node that creates the root span `tx.receive`, runs HashRouter deduplication to avoid processing duplicates, and creates a child `tx.validate` span.
-- **Peer A to Peer B arrow**: The relay message carries trace context (trace_id + parent span_id), enabling Peer B to create a linked span under the same trace.
-- **Peer B (Relay)**: Receives the transaction and trace context, creates a `tx.receive` span linked to Peer A's trace, then relays onward.
-- **Peer C (Validate)**: Final hop in this example. Creates a linked `tx.receive` span and runs `tx.process` to fully process the transaction.
-- **Blue rectangles**: Highlight the span boundaries on each node, showing where instrumentation creates and closes spans.
-
-### Trace Structure
-
-```
-trace_id: abc123
-├── span: tx.receive (Peer A)
-│   ├── span: tx.validate
-│   └── span: tx.relay
-├── span: tx.receive (Peer B) [parent: Peer A]
-│   └── span: tx.relay
-└── span: tx.receive (Peer C) [parent: Peer B]
-    └── span: tx.process

-## 1.4 Consensus Round Flow
-
-Consensus rounds are multi-phase operations that benefit significantly from tracing:
-
-```mermaid
-flowchart TB
-    subgraph round["consensus.round (root span)"]
-        attrs["Attributes:<br/>ledger_seq = 12345678<br/>consensus_mode = proposing<br/>proposers = 35"]
-
-        subgraph open["consensus.phase.open"]
-            open_desc["Duration: ~3s<br/>Waiting for transactions"]
-        end

-        end
-
-        attrs --> open
-        open --> establish
-        establish --> accept
-    end
-
-    style round fill:#f57f17,stroke:#e65100,color:#ffffff

-    style establish fill:#2e7d32,stroke:#1b5e20,color:#ffffff
-    style accept fill:#c2185b,stroke:#880e4f,color:#ffffff
-```
-
-**Reading the diagram:**
-
-- **consensus.round (orange, root span)**: The top-level span encompassing the entire consensus round, with attributes like ledger sequence, mode, and proposer count.
-- **consensus.phase.open (blue)**: The first phase where the node waits (~3s) to collect incoming transactions before proposing.
-- **consensus.phase.establish (green)**: The negotiation phase where validators exchange proposals, resolve disputes, and converge on a transaction set. Child spans track each proposal received/sent and each dispute resolved.
-- **consensus.phase.accept (pink)**: The final phase where the agreed transaction set is applied, a new ledger is built, and the ledger is validated. Child spans cover `ledger.build` and `ledger.validate`.
-- **Arrows (open to establish to accept)**: The sequential flow through the three consensus phases. Each phase must complete before the next begins.

-**Reading the diagram:**
-
-- **rpc.request (green, root span)**: The outermost span representing the full RPC request lifecycle, from HTTP receipt to response. Carries the W3C `traceparent` header for distributed tracing.
-- **HTTP Request node**: Shows the incoming POST request with its `traceparent` header and extracted attributes (method, peer IP, command name).
-- **jobqueue.enqueue (blue)**: The span covering the asynchronous handoff from the RPC thread to the JobQueue worker thread. The trace context is preserved across this async boundary.
-- **rpc.command.submit (orange)**: The span for the actual command execution, with child spans for deserialization, local validation, and network submission.
-- **Response node**: The final output with HTTP status and total duration, marking the end of the root span.
-- **Arrows (top to bottom)**: The sequential processing pipeline -- receive request, extract attributes, enqueue job, execute command, return response.

-| ------------------------- | ---------------------------------------------------------------------------- | ------------------------------------------------ |
-| **Slow RPC**              | Span showing which phase is slow (parsing, execution, serialization)         | Optimize specific code path                      |
-| **Transaction Stuck**     | Trace stops at validation; error attribute shows reason                      | Fix transaction parameters                       |
-| **Consensus Delay**       | Phase.establish taking too long; proposer attribute shows missing validators | Investigate network connectivity                 |
-| **Memory Spike**          | Large batch of spans correlating with memory increase                        | Tune batch_size or sampling                      |
-| **Network Partition**     | Traces missing cross-node links for specific peer                            | Check peer connectivity                          |
-| **Path Computation Slow** | pathfind.compute span shows high latency; cache miss rate in attributes      | Warm the RippleLineCache, check order book depth |
-| **TxQ Full**              | txq.enqueue spans show evictions; fee.escalate spans increasing              | Monitor fee levels, alert operators              |
-| **Ledger Sync Stalled**   | ledger.acquire spans timing out; peer reliability attributes show issues     | Check peer connectivity, add trusted peers       |
-| **UNL Stale**             | validator.list.fetch spans failing; last_update attribute aging              | Verify validator site URLs, check DNS            |
-
-### 1.8.5 Developer Debugging Workflow
-
-1. **Find Transaction**: Query by `tx_hash` to get full trace
-2. **Identify Bottleneck**: Look at span durations to find slowest component
-3. **Check Attributes**: Review `validity`, `rpc_status` for errors
-4. **Correlate Logs**: Use `trace_id` to find related PerfLog entries
-5. **Compare Nodes**: Filter by `service.instance.id` to compare behavior across nodes

-## 2.1 OpenTelemetry Components
-
-> **OTLP** = OpenTelemetry Protocol
-
-### 2.1.1 SDK Selection
-
-**Primary Choice**: OpenTelemetry C++ SDK (`opentelemetry-cpp`)
-
-| Component                               | Purpose                | Required                  |
-| --------------------------------------- | ---------------------- | ------------------------- |
-| `opentelemetry-cpp::api`                | Tracing API headers    | Yes                       |
-| `opentelemetry-cpp::sdk`                | SDK implementation     | Yes                       |
-| `opentelemetry-cpp::ext`                | Extensions (exporters) | Yes                       |
-| `opentelemetry-cpp::otlp_http_exporter` | OTLP/HTTP export       | Yes (shipped in Phase 1b) |
-| `opentelemetry-cpp::otlp_grpc_exporter` | OTLP/gRPC export       | Future (not yet wired up) |
-
-### 2.1.2 Instrumentation Strategy
-
-**Manual Instrumentation** (recommended):
-
-| Approach   | Pros                                                            | Cons                                                    |
-| ---------- | --------------------------------------------------------------- | ------------------------------------------------------- |
-| **Manual** | Precise control, optimized placement, xrpld-specific attributes | More development effort                                 |
-| **Auto**   | Less code, automatic coverage                                   | Less control, potential overhead, limited customization |

-```
-
-**Reading the diagram:**
-
-- **xrpld Nodes (blue)**: The source of telemetry data. Each xrpld node exports spans via OTLP/HTTP on port 4318 (the only exporter shipped in Phase 1b).
-- **OpenTelemetry Collector (red)**: The central aggregation point that receives spans from all nodes. Can run as a sidecar (per-node) or standalone (shared). Handles batching, filtering, and routing.
-- **Observability Backends (green)**: The storage and visualization destinations. Tempo is the recommended backend for both development and production, and Elastic APM is an alternative. The Collector routes to one or more backends.
-- **Arrows (nodes to collector to backends)**: The data pipeline -- spans flow from nodes to the Collector over HTTP, then the Collector fans out to the configured backends.
-
-### 2.2.1 OTLP/HTTP (Shipped in Phase 1b)
-
-OTLP/HTTP is the only exporter wired up in Phase 1b. It is configured via
-`OtlpHttpExporterOptions` with the collector traces endpoint
-(`http://localhost:4318/v1/traces` by default) and a JSON content type
-(binary protobuf is also available).
-
-### 2.2.2 OTLP/gRPC (Future Work — Planned Upgrade)

-OTLP/gRPC is planned as a future upgrade from the HTTP exporter. The gRPC
-transport offers lower per-span overhead and tighter back-pressure semantics
-than HTTP/JSON, making it attractive for production deployments once the HTTP
-path is validated in earlier phases.
-
-Required to land this upgrade:
-
-1. Add `opentelemetry-cpp::otlp_grpc_exporter` to the Conan recipe (the
-   dependency already exists but is not linked in Phase 1b builds).
-2. Extend `TelemetryConfig.cpp` to parse an `exporter` key (`otlp_http`
-   default, `otlp_grpc` opt-in) and a gRPC endpoint override.
-3. In `Telemetry::start()` branch on the parsed exporter type and construct
-   either `OtlpHttpExporterFactory::Create(httpOpts)` or
-   `OtlpGrpcExporterFactory::Create(grpcOpts)` accordingly.
-4. Update the runbook and dashboards to document the alternate port and TLS
-   settings.
-
-When wired up, the gRPC path will use `OtlpGrpcExporterOptions` configured with
-the collector endpoint (host on port 4317), TLS credentials enabled, and a CA
-certificate path.
-
-Until that work lands, `OtlpGrpcExporterOptions` is **not** used by any code
-path in Phase 1b through Phase 5.

-### 2.3.3 Attribute Naming Conventions
-
-Span **names** follow §2.3.1 (dotted `<component>.<operation>`). Span
-**attribute keys** follow the rules below. The constants in the `*SpanNames.h`
-headers are the single source of truth; the collector, Tempo, the Grafana
-dashboards, and the runbook all consume these exact keys, so every layer must
-agree with the code. A CI check enforces this end to end.
-
-1. **Per-span unique attribute** → bare field name, allowed when the field is
-   recorded by a single span/workflow so the span name already supplies the
-   domain (e.g. `command`, `version`, `local` on `rpc.command`).
-2. **Shared attribute (same concept on more than one span)** → ONE key, reused
-   verbatim on every span that records it; the span name tells the occurrences
-   apart, so no per-emitter prefix is added. Name it by the field's meaning: a
-   property of a domain object keeps that object's bare field name (`ledger_hash`,
-   `ledger_seq`, `tx_hash`, `peer_id`, `full_validation`); a field already
-   qualified by a sub-kind keeps that qualifier on every emitter (`proposal_trusted`
-   on both `consensus.proposal.receive` and `peer.proposal.receive`;
-   `validation_trusted` likewise). Defined once in the base `SpanNames.h`
-   `namespace attr` block and re-exported (`using`) by each domain header.
-3. **Collision qualifier** → `<domain>_<field>`, only when a bare name would
-   collide with a DIFFERENT concept in the shared spanmetrics label space or with
-   the OTel-reserved `status` key (e.g. `rpc_status`, `grpc_status`,
-   `consensus_phase`, `consensus_round`, `consensus_mode`). This disambiguates
-   distinct concepts that share a word; it is NOT used to tag the same concept
-   with its emitting workflow — that is rule 2 (one shared name).
-4. **Resource attribute** → dotted `xrpl.<subsystem>.<field>`, reserved ONLY
-   for process/network identity set once at startup (`xrpl.network.id`,
-   `xrpl.network.type`). Span attributes are never dotted in the `xrpl.` form —
-   it blurs the resource/span scope boundary and parses awkwardly in TraceQL.
-5. **Span names** use `<subsystem>[.<component>]` (dotted, per §2.3.1). Only
-   attribute _keys_ follow rules 1–4.
-
-Standard OpenTelemetry semantic-convention keys keep their canonical dotted
-form (e.g. `service.*` resource attributes, `http.*` span attributes); the
-"no dotted form" rule applies to xrpl-custom keys only.
-
-The same rules are recorded in `CONTRIBUTING.md` (the permanent home, since
-`OpenTelemetryPlan/` is removed once the rollout completes). The attribute
-examples in §2.4 below follow these rules.

-### 2.4.1 Resource Attributes (Set Once at Startup)
-
-Resource attributes identify the process and are set once at startup. They use
-the standard OpenTelemetry semantic conventions plus custom dotted `xrpl.*`
-keys (the dotted form is reserved for resource scope per §2.3.3).
-
-| Key                   | Type / value                                            | Description                    |

-| `service.version`     | `build_info::getVersionString()`                        | Standard `SERVICE_VERSION`     |
-| `service.instance.id` | node public key (base58)                                | Standard `SERVICE_INSTANCE_ID` |
-| `xrpl.network.id`     | network id (e.g. 0 for mainnet)                         | Network identifier             |
-| `xrpl.network.type`   | `"mainnet"` \| `"testnet"` \| `"devnet"` \| `"unknown"` | Network kind                   |
-| `xrpl.node.type`      | `"validator"` \| `"stock"` \| `"reporting"`             | Node role                      |
-| `xrpl.node.cluster`   | cluster name                                            | Cluster name, if clustered     |
-
-### 2.4.2 Span Attributes by Category
-
-> Span attribute keys use the underscore form from §2.3.3 (shared/qualified
-> keys are `<domain>_<field>`; per-span unique keys are bare). The dotted form
-> is reserved for the resource attributes in §2.4.1 above. This catalog lists
-> the planned attribute set by category; the exact emitted key for each
-> implemented span is defined by the `*SpanNames.h` constants, which are the
-> single source of truth where the two differ.

-
-> **Note:** `current_ledger_seq` and `ledger_seq` are the same concept — a ledger's sequence number — but they name different ledgers, so the design keeps two keys rather than one. `current_ledger_seq` is the open or in-flight ledger a transaction's work was applied into; it is named after the RPC field `ledger_current_index`. `ledger_seq` (see [Ledger & Job Attributes](#ledger--job-attributes)) is a closed or validated ledger, set by the ledger and consensus spans. Neither is spelled `ledger_index`: per rule 2 of [Telemetry span attribute naming](../CONTRIBUTING.md#telemetry-span-attribute-naming), one concept gets one key reused verbatim, and a different referent is disambiguated with a prefix rather than a synonym.

-### 2.4.4 Privacy & Sensitive Data Policy
-
-> **PII** = Personally Identifiable Information
-
-OpenTelemetry instrumentation is designed to collect **operational metadata only**, never sensitive content.
-
-#### Data NOT Collected
-
-The following data is explicitly **excluded** from telemetry collection:
-
-| Excluded Data           | Reason                                    |
-| ----------------------- | ----------------------------------------- |
-| **Private Keys**        | Never exposed; not relevant to tracing    |
-| **Account Balances**    | Financial data; privacy sensitive         |
-| **Transaction Amounts** | Financial data; privacy sensitive         |
-| **Raw TX Payloads**     | May contain sensitive memo/data fields    |
-| **Personal Data**       | No PII collected                          |
-| **IP Addresses**        | Configurable; excluded by default in prod |
-
-#### Privacy Protection Mechanisms
-
-| Mechanism                     | Description                                                                                                                                                                                         |
-| ----------------------------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
-| **Account Addresses**         | Emitted raw (`pathfind_source_account`, `pathfind_dest_account`). An account address is a public ledger identifier; hashing it protects nothing and breaks the join against explorers, RPC and logs |
-| **Collector Tail Sampling**   | xrpld head sampling is fixed at 1.0 (every span emitted); the collector retains ~10% of non-error traces, reducing stored data exposure                                                             |
-| **Sampling**                  | Only 10% of traces recorded by default, reducing data exposure                                                                                                                                      |
-| **Local Control**             | Node operators have full control over what gets exported                                                                                                                                            |
-| **No Raw Payloads**           | Transaction content is never recorded, only metadata (hash, type, result)                                                                                                                           |
-| **Collector-Level Filtering** | Available for a future genuinely sensitive attribute via an `attributes` processor. None is shipped, and none must be added for account addresses                                                   |
-
-#### Account Addresses
-
-Account addresses are emitted **raw**, at every layer:
-
-1. **SDK-side** (this node): the path-finding RPC handlers set
-   `pathfind_source_account` / `pathfind_dest_account` to the request's
-   r-address, only when it parses as one, and `pathfind_dest_currency` to `to_string(Asset)`,
-   which carries the IOU issuer's r-address. The rationale sits on the attribute
-   constants in `PathFindSpanNames.h`.
-2. **Collector-side**: no collector configuration in this repository hashes
-   or deletes these attributes.
-
-Why raw: an r-address is a public, enumerable identifier on the ledger. An
-unsalted hash of it is reversible by table lookup, so it protects nothing, and
-it breaks the one thing the attribute is for: joining a span to the account as
-explorers, RPC responses and logs show it. The helper `redactAccount()`
-(`xrpl::telemetry`, `Redaction.h`) remains available for a value that is
-genuinely private, but it is applied to no span.
-
-#### Collector-Level Data Protection
-
-No hashing or redaction processor is shipped. If a future span introduces a
-genuinely sensitive attribute, an `attributes` processor in the collector is the
-place to strip it, and the attribute is added to the §2.4 catalogue with that
-note in the same change. Account addresses are not such an attribute.
-
-#### Configuration Options for Privacy
-
-In `xrpld.cfg`, operators control data collection granularity through the
-`[telemetry]` section. Besides `enabled`, per-component toggles
-(`trace_transactions`, `trace_consensus`, `trace_rpc`, `trace_peer` — the last
-often disabled due to high volume) select which spans are emitted. There is no
-redaction setting: account addresses are public and are emitted raw.
-
-> **Key Principle**: Telemetry collects **operational metadata** (timing, counts, hashes, public identifiers) — never **sensitive content** (keys, balances, amounts, raw payloads).

-
-## 2.5 Context Propagation Design
-
-> **WS** = WebSocket
-
-### 2.5.0 Deterministic Trace ID Strategy
-
-Both transaction and consensus tracing use **deterministic trace IDs** derived from
-a globally known hash, so all nodes handling the same workflow independently produce
-spans under the same `trace_id`. This is combined with protobuf `span_id` propagation
-for parent-child relay ordering when available.
-
-#### Transactions — `trace_id = txHash[0:16]`
-
-Every node that handles a transaction knows its `txID` (the `uint256` transaction
-hash). The first 16 bytes of this hash are used as the OTel `trace_id`:
-
-```
-uint256 txHash:  A1B2C3D4 E5F6A7B8 C9D0E1F2 A3B4C5D6  E7F8A9B0 C1D2E3F4 A5B6C7D8 E9F0A1B2
-                 |---------- trace_id (16 bytes) ---------|  (remaining 16 bytes unused)
-```
-
-Each node generates a **random 8-byte `span_id`** so its span is unique within the
-shared trace. When protobuf `TraceContext` is present in the incoming `TMTransaction`,
-the sender's `span_id` is extracted and used as the parent — preserving the relay
-chain as a parent-child tree. When absent (older peers, first hop from client), the
-span appears as a root in the same trace — correlation is preserved, only the tree
-structure degrades.
-
-```
-Node A (submitter)        Node B (relay)          Node C (relay)
-trace_id: A1B2...         trace_id: A1B2...       trace_id: A1B2...
-span_id:  1234 (random)   span_id:  5678 (random) span_id:  9ABC (random)
-parent:   (none)          parent:   1234 (proto)   parent:   5678 (proto)
-                               ↑                        ↑
-                       protobuf propagation      protobuf propagation
-```
-
-If protobuf propagation fails at Node B (old peer):
-
-```
-Node A                    Node B (old peer)       Node C
-trace_id: A1B2...         trace_id: A1B2...       trace_id: A1B2...
-span_id:  1234            span_id:  5678          span_id:  9ABC
-parent:   (none)          parent:   (none)        parent:   5678 (proto)
-                          ↑ no parent, but same trace_id — still grouped
-```
-
-#### Consensus — `trace_id = prevLedgerHash[0:16]`
-
-All validators in the same consensus round share the same `previousLedger.id()`.
-The first 16 bytes are used as trace_id. See [Phase 4a implementation status](./06-implementation-phases.md)
-and `createDeterministicContext()` in `RCLConsensus.cpp` for the implementation.
-
-Switchable via `consensus_trace_strategy` config:
-`"deterministic"` (default) or `"random"` (random trace_id, correlation via attribute queries).
-`"random"` is experimental and not used: it would break cross-node trace correlation.
-
-#### Why Not Random IDs with Propagation Only?
-
-Random trace IDs require **unbroken context propagation** across every hop. In a
-mixed-version network (common during upgrades), older peers silently drop the
-`trace_context` protobuf field. The trace splits and downstream spans become
-impossible to find. Deterministic IDs make correlation **propagation-resilient** — the trace
-backend groups all spans for the same transaction/round regardless of whether
-propagation succeeded.
-
-#### Why Keep Protobuf Propagation?
-
-Deterministic trace IDs alone provide correlation (all spans grouped) but not
-**causality** (which node relayed to which). Protobuf `span_id` propagation adds
-parent-child ordering that shows the exact relay path. The two mechanisms complement
-each other:
-
-| Mechanism                    | Provides                    | Fails when                             |
-| ---------------------------- | --------------------------- | -------------------------------------- |
-| Deterministic trace_id       | Cross-node correlation      | Never (hash is always known)           |
-| Protobuf span_id propagation | Parent-child relay ordering | Older peer drops `trace_context` field |
-
-#### Implementation Reference
-
-The utility function `createDeterministicTxContext(uint256 const& txHash)` follows
-the same pattern as `createDeterministicContext(uint256 const& ledgerId)` in
-`RCLConsensus.cpp`. See [Phase 3 Task 3.9](./Phase3_taskList.md) for the full spec.

-
-**Reading the diagram:**
-
-- **HTTP/WebSocket - RPC (blue)**: For client-facing RPC requests, trace context is propagated using the W3C `traceparent` header. This is the standard approach and works with any OTel-compatible client.
-- **Protocol Buffers - P2P (green)**: For peer-to-peer messages between xrpld nodes, trace context is embedded as a protobuf `TraceContext` message carrying trace_id, span_id, flags, and optional trace_state.
-- **JobQueue - Internal Async (red)**: For asynchronous work within a single node, the OTel context is captured when a job is created and restored when the job executes on a worker thread. This bridges the async gap so spans remain linked.

-## 2.6 Integration with Existing Observability
-
-> **OTLP** = OpenTelemetry Protocol | **WS** = WebSocket
-
-### 2.6.1 Existing Frameworks Comparison
-
-xrpld already has two observability mechanisms. OpenTelemetry complements (not replaces) them:
-
-| Aspect                | PerfLog                       | Beast Insight (StatsD)       | OpenTelemetry             |
-| --------------------- | ----------------------------- | ---------------------------- | ------------------------- |
-| **Type**              | Logging                       | Metrics                      | Distributed Tracing       |
-| **Data**              | JSON log entries              | Counters, gauges, histograms | Spans with context        |
-| **Scope**             | Single node                   | Single node                  | **Cross-node**            |
-| **Output**            | `perf.log` file               | StatsD server                | OTLP Collector            |
-| **Question answered** | "What happened on this node?" | "How many? How fast?"        | "What was the journey?"   |
-| **Correlation**       | By timestamp                  | By metric name               | By `trace_id`             |
-| **Overhead**          | Low (file I/O)                | Low (UDP packets)            | Low-Medium (configurable) |
-
-### 2.6.2 What Each Framework Does Best
-
-#### PerfLog
-
-- **Purpose**: Detailed local event logging for RPC and job execution
-- **Strengths**:
-  - Rich JSON output with timing data
-  - Already integrated in RPC handlers
-  - File-based, no external dependencies
-- **Limitations**:
-  - Single-node only (no cross-node correlation)
-  - No parent-child relationships between events
-  - Manual log parsing required
-
-A PerfLog entry is a JSON object with fields such as `time`, `method`,
-`duration_us`, and `result`.
-
-#### Beast Insight (StatsD)
-
-- **Purpose**: Real-time metrics for monitoring dashboards
-- **Strengths**:
-  - Aggregated metrics (counters, gauges, histograms)
-  - Low overhead (UDP, fire-and-forget)
-  - Good for alerting thresholds
-- **Limitations**:
-  - No request-level detail
-  - No causal relationships
-  - Single-node perspective
-  - Aggregation happens on the StatsD server, not in the process
-
-In xrpld, Beast Insight is used through `increment` (counters), `gauge`
-(point-in-time values), and `timing` (durations) calls. A `timing` call sends
-each measured value as its own raw `|ms` sample, so the histogram a dashboard
-reads is built by the StatsD server from that stream of values.
-
-#### OpenTelemetry (NEW)
-
-- **Purpose**: Distributed request tracing across nodes
-- **Strengths**:
-  - **Cross-node correlation** via `trace_id`
-  - Parent-child span relationships
-  - Rich attributes per span
-  - A `Histogram` instrument that aggregates **at the point of measure**
-  - Industry standard (CNCF)
-- **Limitations**:
-  - Requires collector infrastructure
-  - Higher complexity than logging
-
-A span is created via `startSpan` (e.g. `"tx.relay"`), annotated with
-attributes such as `tx_hash` and `peer_id`, and is automatically linked to its
-parent through the active context.
-
-OpenTelemetry is not only spans. The same SDK offers a `Histogram` instrument,
-and a `Record()` call folds the value straight into bucket counts inside the
-process — no per-event record is shipped and no server-side aggregation step is
-needed. That is what makes it affordable in a hot loop where one span per event
-would not be, and it is the one thing Beast Insight cannot do, because its
-`timing` path ships raw values and aggregates them on the StatsD server.
-
-### 2.6.3 When to Use Each
-
-| Scenario                                | PerfLog    | StatsD | OpenTelemetry |
-| --------------------------------------- | ---------- | ------ | ------------- |
-| "How many TXs per second?"              | ❌         | ✅     | ✅            |
-| "What's the p99 RPC latency?"           | ❌         | ✅     | ✅            |
-| "Why was this specific TX slow?"        | ⚠️ partial | ❌     | ✅            |
-| "Which node delayed consensus?"         | ❌         | ❌     | ✅            |
-| "What happened on node X at time T?"    | ✅         | ❌     | ✅            |
-| "Show me the TX journey across 5 nodes" | ❌         | ❌     | ✅            |
-| "p99 NodeStore fetch latency?"          | ❌         | ❌     | ✅            |
-
-The last row is the case a span cannot answer. One `TMGetObjectByHash` message
-requests up to `tuning::kHardMaxReplyNodes` objects, so a span per NodeStore
-fetch is not affordable in that loop. Instead the fetch loop's wall time is
-recorded once per message into an OpenTelemetry `Histogram`
-(`getobject_lookup_us`), and the quantile is read off its buckets. StatsD is
-marked ❌ because that instrument is recorded on the native OpenTelemetry metrics
-path, not through Beast Insight.

-
-**Reading the diagram:**
-
-- **xrpld Process (dark gray)**: The single xrpld node running all three observability frameworks side by side. Each framework operates independently with no interference.
-- **PerfLog to perf.log**: PerfLog writes JSON-formatted event logs to a local file. Grafana can ingest these via Loki or a file-based datasource.
-- **Beast Insight to StatsD Server**: Insight sends aggregated metrics (counters, gauges) over UDP to a StatsD server. Grafana reads from StatsD-compatible backends like Graphite or Prometheus (via StatsD exporter).
-- **OpenTelemetry to OTLP Collector**: OTel exports spans over OTLP/HTTP to a Collector, which then forwards to a trace backend (Tempo). (OTLP/gRPC is future work — §2.2.2.)
-- **Grafana (red, unified UI)**: All three data streams converge in Grafana, enabling operators to correlate logs, metrics, and traces in a single dashboard.
-
-### 2.6.5 Correlation with PerfLog
-
-Trace IDs can be correlated with existing PerfLog entries for comprehensive
-debugging. The design is for `RPCHandler.cpp` to start an `rpc.command.<method>`
-span alongside the existing PerfLog `rpcStart`/`rpcFinish`/`rpcError` calls,
-extract the span's `trace_id` (when valid), and eventually stamp it onto the
-PerfLog entry (a planned `setTraceId` hook) so logs and traces share a key. The
-span status is set to OK on success or to error (recording the exception) on
-failure.

-### Key Principles
-
-1. **Minimal Intrusion**: Instrumentation should not alter existing control flow
-2. **Zero-Cost When Disabled**: Use compile-time flags and no-op implementations
-3. **Backward Compatibility**: Protocol Buffer extensions use high field numbers
-4. **Graceful Degradation**: Tracing failures must not affect node operation

-| ------------- | ---------- | ------------------------------------------------ |
-| CPU           | 1-3%       | Of per-transaction CPU cost (~200μs baseline)    |
-| Memory        | ~10 MB     | SDK statics + batch buffer + worker thread stack |
-| Network       | 10-50 KB/s | Compressed OTLP export to collector              |
-| Latency (p99) | <2%        | With proper sampling configuration               |
-
----
-
-## 3.4 Detailed CPU Overhead Analysis
-
-### 3.4.1 Per-Operation Costs
-
-> **Note on hardware assumptions**: The costs below are based on the official OTel C++ SDK CI benchmarks
-> (969 runs on GitHub Actions 2-core shared runners). On production server hardware (3+ GHz Xeon),
-> expect costs at the **lower end** of each range (~30-50% improvement over CI hardware).
-
-| Operation             | Time (ns) | Frequency              | Impact     |
-| --------------------- | --------- | ---------------------- | ---------- |
-| Span creation         | 500-1000  | Every traced operation | Low        |
-| Span end              | 100-200   | Every traced operation | Low        |
-| SetAttribute (string) | 80-120    | 3-5 per span           | Low        |
-| SetAttribute (int)    | 40-60     | 2-3 per span           | Negligible |
-| AddEvent              | 100-200   | 0-2 per span           | Low        |
-| Context injection     | 150-250   | Per outgoing message   | Low        |
-| Context extraction    | 100-180   | Per incoming message   | Low        |
-| GetCurrent context    | 10-20     | Thread-local access    | Negligible |
-
-**Source**: Span creation based on OTel C++ SDK `BM_SpanCreation` benchmark (AlwaysOnSampler +
-SimpleSpanProcessor + InMemoryExporter), median ~1,000 ns on CI hardware. AddEvent includes
-timestamp read + string copy + vector push + mutex acquisition. Context injection/extraction
-confirmed by `BM_SpanCreationWithScope` benchmark delta (~160 ns).
-
-### 3.4.2 Transaction Processing Overhead
-
-<div align="center">
-
-```mermaid
-%%{init: {'pie': {'textPosition': 0.75}}}%%
-pie showData
-    "tx.receive (1400ns)" : 1400
-    "tx.validate (1200ns)" : 1200
-    "tx.relay (1200ns)" : 1200
-    "Context inject (200ns)" : 200
-```
-
-**Transaction Tracing Overhead (~4.0μs total)**
-
-</div>
-
-**Overhead percentage**: 4.0 μs / 200 μs (avg tx processing) = **~2.0%**
-
-> **Breakdown**: Each span (tx.receive, tx.validate, tx.relay) costs ~1,000 ns for creation plus
-> ~200-400 ns for 3-5 attribute sets. Context injection is ~200 ns (confirmed by benchmarks).
-> On production hardware, expect ~2.6 μs total (~1.3% overhead) due to faster span creation (~500-600 ns).
-
-### 3.4.3 Consensus Round Overhead
-
-| Operation              | Count | Cost (ns) | Total      |
-| ---------------------- | ----- | --------- | ---------- |
-| consensus.round span   | 1     | ~1200     | ~1.2 μs    |
-| consensus.phase spans  | 3     | ~1100     | ~3.3 μs    |
-| proposal.receive spans | ~20   | ~1100     | ~22 μs     |
-| proposal.send spans    | ~3    | ~1100     | ~3.3 μs    |
-| Context operations     | ~30   | ~200      | ~6 μs      |
-| **TOTAL**              |       |           | **~36 μs** |
-
-> **Why higher**: Each span costs ~1,000 ns creation + ~100-200 ns for 1-2 attributes, totaling ~1,100-1,200 ns.
-> Context operations remain ~200 ns (confirmed by benchmarks). On production hardware, expect ~24 μs total.
-
-**Overhead percentage**: 36 μs / 3s (typical round) = **~0.001%** (negligible)
-
-### 3.4.4 RPC Request Overhead
-
-| Operation        | Cost (ns)    |
-| ---------------- | ------------ |
-| rpc.request span | ~1200        |
-| rpc.command span | ~1100        |
-| Context extract  | ~250         |
-| Context inject   | ~200         |
-| **TOTAL**        | **~2.75 μs** |
-
-> **Why higher**: Each span costs ~1,000 ns creation + ~100-200 ns for attributes (command name,
-> version, role). Context extract/inject costs are confirmed by OTel C++ benchmarks.
-
-- Fast RPC (1ms): 2.75 μs / 1ms = **~0.275%**
-- Slow RPC (100ms): 2.75 μs / 100ms = **~0.003%**

-## 3.5 Memory Overhead Analysis
-
-> **OTLP** = OpenTelemetry Protocol
-
-### 3.5.1 Static Memory
-
-| Component                            | Size        | Allocated  |
-| ------------------------------------ | ----------- | ---------- |
-| TracerProvider singleton             | ~64 KB      | At startup |
-| BatchSpanProcessor (circular buffer) | ~16 KB      | At startup |
-| BatchSpanProcessor (worker thread)   | ~8 MB       | At startup |
-| OTLP/HTTP exporter (client init)     | ~64 KB      | At startup |
-| Propagator registry                  | ~8 KB       | At startup |
-| **Total static**                     | **~8.1 MB** |            |
-
-> **Why higher than earlier estimate**: The BatchSpanProcessor's circular buffer itself is only ~16 KB
-> (2049 x 8-byte `AtomicUniquePtr` entries), but it spawns a dedicated worker thread whose default
-> stack size on Linux is ~8 MB. The OTLP/HTTP exporter allocates a small client and TLS
-> initialization buffer. The worker thread stack dominates the static footprint.
-
-### 3.5.2 Dynamic Memory
-
-| Component            | Size per unit  | Max units  | Peak            |
-| -------------------- | -------------- | ---------- | --------------- |
-| Active span          | ~500-800 bytes | 1000       | ~500-800 KB     |
-| Queued span (export) | ~500 bytes     | 2048       | ~1 MB           |
-| Attribute storage    | ~80 bytes      | 5 per span | Included        |
-| Context storage      | ~64 bytes      | Per thread | ~6.4 KB         |
-| **Total dynamic**    |                |            | **~1.5-1.8 MB** |
-
-> **Why active spans are larger**: An active `Span` object includes the wrapper (~88 bytes: shared_ptr,
-> mutex, unique_ptr to Recordable) plus `SpanData` (~250 bytes: SpanContext, timestamps, name, status,
-> empty containers) plus attribute storage (~200-500 bytes for 3-5 string attributes in a `std::map`).
-> Source: `sdk/src/trace/span.h` and `sdk/include/opentelemetry/sdk/trace/span_data.h`.
-> Queued spans release the wrapper, keeping only `SpanData` + attributes (~500 bytes).

-```
-
-**Notes**:
-
-- Memory increases with span rate but **plateaus at queue capacity** (default 2048 spans)
-- Batch export prevents unbounded growth
-- At queue limit, oldest spans are dropped (not blocked)
-- Maximum memory is bounded: ~8.3 MB static (dominated by worker thread stack) + 2048 queued spans x ~500 bytes (~1 MB) + active spans (~0.8 MB) ≈ **~10 MB ceiling**
-- The worker thread stack (~8 MB) is virtual memory; actual RSS depends on stack usage (typically much less)
-
-> **Measured outcome**: A perf-iac comparison (telemetry compiled-in + enabled vs compiled-out,
-> 9 nodes — validators and client-handlers — under sustained payment load) recorded **no measurable
-> RSS increase over the telemetry-off baseline** (~15 GiB mean / ~18–19 GiB peak on both sides),
-> with no OOM, no swap, and no leak across the run. The ~10 MB ceiling above is therefore a
-> provisioning safety margin (dominated by virtual thread-stack address space), not an expected
-> resident-memory increase. Steady-state cost shows up as throughput (~3–4% at head sampling 1.0),
-> not memory.

-## 3.6 Network Overhead Analysis
-
-### 3.6.1 Export Bandwidth
-
-> **Bytes per span**: Estimates use ~500 bytes/span (conservative upper bound). OTLP protobuf analysis
-> shows a typical span with 3-5 string attributes serializes to ~200-300 bytes raw; with gzip
-> compression (~60-70% of raw) and batching (amortized headers), ~350 bytes/span is more realistic.
-> The table uses the conservative estimate for capacity planning.
-
-| Sampling Rate | Spans/sec | Bandwidth | Notes            |
-| ------------- | --------- | --------- | ---------------- |
-| 100%          | ~500      | ~250 KB/s | Development only |
-| 10%           | ~50       | ~25 KB/s  | Staging          |
-| 1%            | ~5        | ~2.5 KB/s | Production       |
-| Error-only    | ~1        | ~0.5 KB/s | Minimal overhead |

-### 3.7.2 Batch Tuning Recommendations
-
-| Environment        | Batch Size | Batch Delay | Max Queue |
-| ------------------ | ---------- | ----------- | --------- |
-| Low-latency        | 128        | 1000ms      | 512       |
-| High-throughput    | 1024       | 10000ms     | 8192      |
-| Memory-constrained | 256        | 2000ms      | 512       |
-
-### 3.7.3 Conditional Instrumentation
-
-Instrumentation is gated on two levels. A compile-time feature flag (`XRPL_ENABLE_TELEMETRY`) reduces the trace macros to no-ops when telemetry is built out, so disabled builds carry zero cost. At runtime, per-component guards (e.g. `shouldTracePeer()`) skip span creation for components whose tracing is turned off, incurring no overhead beyond a single boolean check.

-### 3.9.4 Architectural Impact Assessment
-
-| Aspect               | Impact  | Justification                                                                    |
-| -------------------- | ------- | -------------------------------------------------------------------------------- |
-| **Data Flow**        | Minimal | Read-only instrumentation; no modification to consensus or transaction data flow |
-| **Threading Model**  | Minimal | Context propagation uses thread-local storage (standard OTel pattern)            |
-| **Memory Model**     | Low     | Bounded queues prevent unbounded growth; RAII ensures cleanup                    |
-| **Network Protocol** | Low     | Optional fields in protobuf (high field numbers); backward compatible            |
-| **Configuration**    | None    | New config section; existing configs unaffected                                  |
-| **Build System**     | Low     | Optional CMake flag; builds work without OpenTelemetry                           |
-| **Dependencies**     | Low     | OpenTelemetry SDK is optional; null implementation when disabled                 |
-
-### 3.9.5 Backward Compatibility
-
-| Compatibility   | Status  | Notes                                                 |
-| --------------- | ------- | ----------------------------------------------------- |
-| **Config File** | ✅ Full | New `[telemetry]` section is optional                 |
-| **Protocol**    | ✅ Full | Optional protobuf fields with high field numbers      |
-| **Build**       | ✅ Full | `XRPL_ENABLE_TELEMETRY=OFF` produces identical binary |
-| **Runtime**     | ✅ Full | `enabled=0` produces zero overhead                    |
-| **API**         | ✅ Full | No changes to public RPC or P2P APIs                  |
-
-### 3.9.6 Rollback Strategy
-
-If issues are discovered after deployment:
-
-1. **Immediate**: Set `enabled=0` in config and restart (zero code change)
-2. **Quick**: Rebuild with `XRPL_ENABLE_TELEMETRY=OFF`
-3. **Complete**: Revert telemetry commits (clean separation makes this easy)
-
-### 3.9.7 Code Change Examples
-
-**Minimal RPC Instrumentation (Low Intrusiveness):** Instrumenting an RPC handler adds roughly 3-4 lines: one macro to start the span and one or two `setAttribute` calls (command name, status). The span ends automatically via RAII, so the existing control flow — process the request, send the result — is untouched.
-
-**Consensus Instrumentation (Medium Intrusiveness):** Consensus is slightly more intrusive because child spans in later phase transitions need the round's context. Beyond the span-start and attribute macros, this requires storing the active context in a new member variable (`currentRoundContext_`) at round start. The existing round logic itself remains unchanged.

-## 5.1 xrpld Configuration
-
-> **OTLP** = OpenTelemetry Protocol | **TxQ** = Transaction Queue | **mTLS** = mutual TLS
-
-### 5.1.1 Configuration File Section
-
-The authoritative `[telemetry]` example lives in `cfg/xrpld-example.cfg`. Telemetry is disabled by default (`enabled=0`); enabling it turns on distributed tracing for transaction flow, consensus, and RPC calls, with traces exported to an OpenTelemetry Collector over OTLP. Head sampling is intentionally fixed at 1.0 (sample everything) and is not configurable — per-node head-sampling would produce broken/partial distributed traces, so volume reduction is delegated to the collector's tail sampling (see Section 7.4.2). The full option reference follows.
-

-## 5.2 Configuration Parser
-
-> **TxQ** = Transaction Queue
-
-The parser `makeTelemetrySetup()` in `src/libxrpl/telemetry/TelemetryConfig.cpp` reads the `[telemetry]` `Section` and populates a `Telemetry::Setup` struct, applying the defaults listed in Section 5.1.2 via `section.valueOr(...)`. It derives `serviceInstanceId` from the node public key when not overridden, selects the exporter endpoint default by exporter type, and leaves the sampling ratio at its fixed 1.0 default (not read from config — see Section 7.4.2).
-
----
-
-## 5.3 Application Integration
-
-### 5.3.1 ApplicationImp Changes
-
-> **Deferred identity**: The node public key (`nodeIdentity_`) is not
-> available during `ApplicationImp`'s member initializer list — it is
-> resolved later in `setup()`. The `Telemetry` object is therefore
-> constructed with an empty `serviceInstanceId` and patched via
-> `setServiceInstanceId()` once `setup()` has called `getNodeIdentity()`.
-
-`ApplicationImp` (in `src/xrpld/app/main/Application.cpp`) owns a `std::unique_ptr<telemetry::Telemetry> telemetry_`. It is built in the member initializer list via `makeTelemetry(makeTelemetrySetup(...))` with an empty `serviceInstanceId`, then patched in `setup()` by calling `setServiceInstanceId()` with the Base58 node public key (unless the user supplied a custom `service_instance_id`). `start()` and `run()` forward to `telemetry_->start()` / `telemetry_->stop()`, and `getTelemetry()` returns the owned instance.
-
-### 5.3.2 ServiceRegistry Interface Addition
-
-`include/xrpl/core/ServiceRegistry.h` gains a pure-virtual `telemetry::Telemetry& getTelemetry()` (with a forward declaration of `telemetry::Telemetry`), giving every component a uniform accessor for the tracing subsystem.
-
-> **Note:** `Application` extends `ServiceRegistry`, so `getTelemetry()` is
-> available on both. Components that hold a `ServiceRegistry&` (e.g.
-> `NetworkOPsImp`) call `registry_.get().getTelemetry()`. Components that
-> still hold an `Application&` (e.g. `ServerHandler`, `PeerImp`,
-> `RCLConsensus::Adaptor`) call `app_.getTelemetry()` directly.
-
----
-
-## 5.4 CMake Integration
-
-> **OTLP** = OpenTelemetry Protocol
-
-### 5.4.1 Find OpenTelemetry Module
-
-A `cmake/FindOpenTelemetry.cmake` module locates the OpenTelemetry C++ SDK. It first tries `find_package(opentelemetry-cpp CONFIG)`, aliasing the imported targets `OpenTelemetry::api`, `OpenTelemetry::sdk`, and `OpenTelemetry::otlp_grpc_exporter`, and falls back to `pkg-config` when no CMake config package is present.
-
-### 5.4.2 CMakeLists.txt Changes
-
-The top-level `CMakeLists.txt` adds an `XRPL_ENABLE_TELEMETRY` option (default `OFF`). When enabled, it runs `find_package(OpenTelemetry REQUIRED)`, defines the `XRPL_ENABLE_TELEMETRY` compile flag, and builds the `xrpl_telemetry` library from the real telemetry sources linked against the OpenTelemetry targets; when disabled, it builds the same target from a no-op `NullTelemetry.cpp` so call sites compile unchanged.
-
----
-
-## 5.5 OpenTelemetry Collector Configuration
-
-> **OTLP** = OpenTelemetry Protocol | **APM** = Application Performance Monitoring
-
-The authoritative collector config lives in the repo at `docker/telemetry/otel-collector-config.yaml` (with Tempo backend config in `docker/telemetry/tempo.yaml`). The sections below summarize the development and production shapes of that pipeline.
-
-### 5.5.1 Development Configuration
-
-The development collector enables an OTLP receiver on both gRPC (`0.0.0.0:4317`) and HTTP (`0.0.0.0:4318`), a single `batch` processor (1s timeout, batch size 100), and two exporters: a `logging` exporter for console debugging and `otlp_grpc/tempo` (insecure) for trace visualization. The single `traces` pipeline wires receiver → batch → both exporters.
-
-### 5.5.2 Production Configuration
-
-The production collector adds TLS on the OTLP gRPC receiver and a richer processor chain: a `memory_limiter` (OOM guard), `batch` (5s timeout, size 512), `tail_sampling`, and an `attributes` processor that stamps `deployment.environment`. Account addresses are public identifiers and are not hashed at any layer. Tail sampling keeps all `ERROR` traces, slow consensus rounds (>5s) and slow RPC requests (>1s), and probabilistically samples the remainder at 10%. Exporters target Grafana Tempo (TLS) and Elastic APM; `health_check` and `zpages` extensions are enabled for operability.
-
----
-
-## 5.6 Docker Compose Development Environment
-
-> **OTLP** = OpenTelemetry Protocol
-
-The authoritative development stack lives in the repo at `docker/telemetry/docker-compose.yml`. It brings up four services on a shared `xrpld-telemetry` network: an `otel-collector` (otel/opentelemetry-collector-contrib) exposing OTLP gRPC `4317`, OTLP HTTP `4318`, and health check `13133`; `tempo` for trace storage/visualization; `grafana` with provisioned datasources and dashboards (anonymous admin enabled); and an optional `prometheus` for metric correlation.

-**Reading the diagram:**
-
-- **Configuration Sources**: `xrpld.cfg` provides runtime settings (endpoint, per-component trace toggles) while the CMake flag controls whether telemetry is compiled in at all. Head sampling is fixed at 1.0 and is not a config option; volume reduction happens via tail sampling in the collector.
-- **Initialization**: `makeTelemetrySetup()` parses config values, then `makeTelemetry()` constructs the provider, processor, and exporter objects.
-- **Runtime Components**: The `TracerProvider` creates spans, the `BatchProcessor` buffers them, and the `OTLP Exporter` serializes and sends them over the wire.
-- **OTLP arrow to Collector**: Trace data leaves the xrpld process via OTLP/HTTP and enters the external Collector pipeline. (OTLP/gRPC is future work — see design decisions §2.2.2.)
-- **Collector Pipeline**: `Receivers` ingest OTLP data, `Processors` apply sampling/filtering/enrichment, and `Exporters` forward traces to storage backends (Tempo, etc.).

-## 5.8 Grafana Integration
-
-> **APM** = Application Performance Monitoring
-
-Step-by-step instructions for integrating xrpld traces with Grafana.
-
-### 5.8.1 Data Source Configuration
-
-#### Tempo (Recommended)
-
-A Tempo datasource (`grafana/provisioning/datasources/tempo.yaml`, provisioned from `docker/telemetry/grafana/`) points at `http://tempo:3200` and enables `tracesToLogs` (linking to Loki on `service.name`/`tx_hash` and mapping `trace_id` → `traceID`), `serviceMap` against Prometheus, the node graph, and Loki search.
-
-#### Elastic APM
-
-Alternatively, an Elasticsearch datasource (`grafana/provisioning/datasources/elastic-apm.yaml`) of type `elasticsearch` points at `http://elasticsearch:9200` against the `apm-*` index, using `@timestamp` as the time field and mapping the log message/level fields.
-
-### 5.8.2 Dashboard Provisioning
-
-A dashboard provider (`grafana/provisioning/dashboards/dashboards.yaml`) loads the `xrpld` dashboard folder from disk (`/var/lib/grafana/dashboards/rippled`), polling for changes every 30s with deletion disabled.
-
-### 5.8.3 Example Dashboard: RPC Performance
-
-An example `xrpld RPC Performance` dashboard (uid `xrpld-rpc-performance`) sourced from Tempo via TraceQL provides four panels: RPC latency by command (heatmap), RPC error rate by command (timeseries), the top 10 slowest RPC commands by average duration (table), and a recent-traces table.
-
-### 5.8.4 Example Dashboard: Transaction Tracing
-
-An example `xrpld Transaction Tracing` dashboard (uid `xrpld-tx-tracing`) over Tempo provides three panels: transaction throughput (`tx.receive` rate, stat), cross-node relay count (average `span.relay_count` on `tx.relay`, timeseries), and a table of transaction validation errors (`tx.validate` with `status = error`).
-
-### 5.8.5 TraceQL Query Examples
-
-Common queries for xrpld traces:
-
-```
-# Find all traces for a specific transaction hash
-{resource.service.name="xrpld" && span.tx_hash="ABC123..."}
-
-# Find slow RPC commands (>100ms)
-{resource.service.name="xrpld" && name=~"rpc.command.*"} | { duration > 100ms }
-
-# Find consensus rounds taking >5 seconds
-{resource.service.name="xrpld" && name="consensus.round"} | { duration > 5s }
-
-# Find failed transactions with error details
-{resource.service.name="xrpld" && name="tx.validate" && status = error}
-
-# Find transactions relayed to many peers
-{resource.service.name="xrpld" && name="tx.relay"} | { span.relay_count > 10 }
-
-# Compare latency across nodes
-{resource.service.name="xrpld" && name="rpc.command.account_info"} | avg_over_time(duration) by (resource.service.instance.id)
-```
-
-### 5.8.6 Correlation with PerfLog
-
-To correlate OpenTelemetry traces with existing PerfLog data:
-
-**Step 1: Configure Loki to ingest PerfLog**
-
-Configure a Promtail scrape job (`promtail-config.yaml`) that tails `/var/log/rippled/perf*.log`, parses each JSON line, and promotes `trace_id`, `ledger_seq`, and `tx_hash` to Loki labels.
-
-**Step 2: Add trace_id to PerfLog entries**
-
-Modify PerfLog so its JSON output includes a `trace_id` field whenever a valid span is active: fetch the current span from the OpenTelemetry runtime context, and if its context is valid, render the trace ID as a 32-character lowercase hex string into the log entry.
-
-**Step 3: Configure Grafana trace-to-logs link**
-
-In the Tempo datasource, set the `tracesToLogs` derived field to link to Loki on the `trace_id` and `tx_hash` tags, with `filterByTraceID: true`.
-
-### 5.8.7 Correlation with Insight/StatsD Metrics
-
-To correlate traces with existing Beast Insight metrics:
-
-**Step 1: Export Insight metrics to Prometheus**
-
-Add a Prometheus scrape job (`prometheus.yaml`) named `xrpld-statsd` targeting the StatsD exporter at `statsd-exporter:9102`.
-
-**Step 2: Add exemplars to metrics**
-
-The OpenTelemetry SDK automatically adds exemplars (trace IDs) to metrics when using the Prometheus exporter, linking metric spikes to specific traces.
-
-**Step 3: Configure Grafana metric-to-trace link**
-
-In the Prometheus datasource, set `exemplarTraceIdDestinations` to map the `trace_id` exemplar to the Tempo datasource.
-
-**Step 4: Dashboard panel with exemplars**
-
-Add a timeseries panel over Prometheus (e.g. `histogram_quantile(0.99, rate(xrpld_rpc_duration_seconds_bucket[5m]))`) with `exemplar: true` enabled.
-
-This allows clicking on metric data points to jump directly to the related trace.

-
-### Deterministic Trace ID (Task 3.9)
-
-Transaction spans use **deterministic trace IDs** derived from the transaction hash:
-`trace_id = txHash[0:16]`. All nodes handling the same transaction independently
-produce spans under the same trace_id. Protobuf `span_id` propagation (Task 3.7)
-additionally provides parent-child relay ordering when available. See
-[02-design-decisions.md §2.5.0](./02-design-decisions.md) for the design rationale
-and [Phase3_taskList.md Task 3.9](./Phase3_taskList.md) for the full implementation spec.
-
-### Exit Criteria
-
-- [ ] Transaction traces span across nodes
-- [ ] Trace context in Protocol Buffer messages
-- [ ] HashRouter deduplication visible in traces
-- [ ] Multi-node integration tests passing
-- [ ] <5% overhead on transaction throughput
-- [ ] Deterministic trace_id: all nodes produce same trace_id for same transaction
-- [ ] Protobuf span_id propagation preserves parent-child ordering when available

-
-### Exit Criteria
-
-- [x] Complete consensus round traces
-- [x] Phase transitions visible (open, establish, close, accept)
-- [x] Proposals and validations traced — send and receive; relay deferred to Phase 4b
-- [x] Close time agreement tracked (per `avCT_CONSENSUS_PCT`)
-- [x] No impact on consensus timing
-- [ ] Multi-validator test network validated
-- [x] Transaction-consensus correlation (Task 4.6) — `tx.included` events in doAccept
-- [ ] Validation span enrichment (Task 4.8) — not implemented
-
-### Implementation Status — Phase 4a Complete
-
-Phase 4a (establish-phase gap fill & cross-node correlation) adds:
-
-- **Deterministic trace ID** derived from `previousLedger.id()` so all validators
-  in the same round share the same `trace_id` (switchable via
-  `consensus_trace_strategy` config: `"deterministic"`, or `"random"` which is
-  experimental and not used).
-  See [Configuration Reference](./05-configuration-reference.md) for full
-  configuration options.
-- **Round lifecycle spans**: `consensus.round` with round-to-round span links.
-- **Establish phase**: `consensus.establish`, `consensus.update_positions` (with
-  `dispute.resolve` events), `consensus.check` (with threshold tracking).
-- **Mode changes**: `consensus.mode_change` spans.
-- **Validation**: `consensus.validation.send` with span link to round span
-  (thread-safe cross-thread access via `roundSpanContext_` snapshot).
-- **Separation of concerns**: telemetry extracted to private helpers
-  (`startRoundTracing`, `createValidationSpan`, `startEstablishTracing`,
-  `updateEstablishTracing`, `endEstablishTracing`).
-
-See [Phase4_taskList.md](./Phase4_taskList.md) for the full spec and implementation notes.

-
-## 6.5a Phase 4a: Establish-Phase Gap Fill & Cross-Node Correlation
-
-**Objective**: Fill tracing gaps in the establish phase and establish cross-node
-correlation using deterministic trace IDs derived from `previousLedger.id()`.
-
-**Approach**: Direct instrumentation in `Consensus.h` and `RCLConsensus.cpp`.
-All spans use `SpanGuard` factory methods (`span()`, `hashSpan()`, `linkedSpan()`)
-with `TraceCategory::Consensus` gating. No macros used — all tracing via direct
-`SpanGuard` API calls.

-
-**Objective**: Wire `TraceContextPropagator` for P2P messages (proposals,
-validations) to enable true distributed tracing between nodes.

-**Status**: Partially implemented. Send-side injection (proposals and
-validations) and receive-side extraction (`consensus.{proposal,validation}.
-receive` spans parented on the sender's context) are wired in Phase 4a.
-Remaining Phase 4b work: relay spans in `share(RCLCxPeerPos)` and multi-node

-**Reading the diagram:**
-
-- **CRAWL (Weeks 1-2)**: Minimal investment -- set up the SDK, instrument RPC and PathFinding/TxQ handlers, and verify on a single node. Delivers immediate latency visibility.
-- **WALK (Weeks 3-5)**: Expand to transaction lifecycle tracing, fee escalation, cross-node context propagation, and basic Grafana dashboards. This is where distributed tracing starts working.
-- **RUN (Weeks 6-9)**: Full consensus instrumentation, establish-phase gap fill, cross-node correlation, StatsD integration, and production deployment with sampling and alerting.
-- **Arrows (crawl → walk → run)**: Each phase builds on the prior one; you cannot skip ahead because later phases depend on infrastructure established earlier.
-
-### 6.9.2 Quick Wins (Immediate Value)
-
-| Quick Win                      | Value  | When to Deploy |
-| ------------------------------ | ------ | -------------- |
-| **RPC Command Tracing**        | High   | Week 2         |
-| **RPC Latency Histograms**     | High   | Week 2         |
-| **Error Rate Dashboard**       | Medium | Week 2         |
-| **Transaction Submit Tracing** | High   | Week 3         |
-| **Consensus Round Duration**   | Medium | Week 6         |
-
-### 6.9.3 CRAWL Phase (Weeks 1-2)
-
-**Goal**: Get basic tracing working with minimal code changes.
-
-**What You Get**:
-
-- RPC request/response traces for all commands
-- Latency breakdown per RPC command
-- PathFinding and TxQ tracing (directly impacts RPC latency)
-- Error visibility with stack traces
-- Basic Grafana dashboard
-
-**Code Changes**: ~15 lines in `ServerHandler.cpp`, ~40 lines in new telemetry module
-
-**Why Start Here**:
-
-- RPC is the lowest-risk, highest-visibility component
-- PathFinding and TxQ are RPC-adjacent and directly affect latency
-- Immediate value for debugging client issues
-- No cross-node complexity
-- Single file modification to existing code
-
-### 6.9.4 WALK Phase (Weeks 3-5)
-
-**Goal**: Add transaction lifecycle tracing across nodes.
-
-**What You Get**:
-
-- End-to-end transaction traces from submit to relay
-- Fee escalation tracing within the transaction pipeline
-- Cross-node correlation (see transaction path)
-- HashRouter deduplication visibility
-- Relay latency metrics
-
-**Code Changes**: ~120 lines across 4 files, plus protobuf extension
-
-**Why Do This Second**:
-
-- Builds on RPC tracing (transactions submitted via RPC)
-- Fee escalation is integral to the transaction processing pipeline
-- Moderate complexity (requires context propagation)
-- High value for debugging transaction issues
-
-### 6.9.5 RUN Phase (Weeks 6-9)
-
-**Goal**: Full observability including consensus.
-
-**What You Get**:
-
-- Complete consensus round visibility
-- Phase transition timing
-- Validator proposal tracking
-- ~~Validator list and manifest tracing~~ — descoped
-- ~~Amendment voting tracing~~ — descoped
-- ~~SHAMap sync tracing~~ — descoped
-- Full end-to-end traces (client → RPC → TX → consensus → ledger) — partial (tx-consensus correlation not yet done)
-
-**Code Changes**: ~100 lines across 3 consensus files
-
-**Why Do This Last**:
-
-- Highest complexity (consensus is critical path)
-- Validator, amendment, and SHAMap components were descoped (lower priority)
-- Requires thorough testing
-- Lower relative value (consensus issues are rarer)

-**Reading the diagram:**
-
-- **Week 1 (tasks 1-2)**: Foundation work -- integrate the OpenTelemetry SDK via Conan/CMake and build the `Telemetry` interface with `SpanGuard` and config parsing.
-- **Week 2 (tasks 3-4)**: First observable output -- instrument `ServerHandler` for RPC tracing and stand up Tempo so developers can see traces immediately.
-- **Weeks 3-5 (tasks 5-10)**: Transaction lifecycle -- add submit tracing, build the first Grafana dashboard, extend protobuf for cross-node context, instrument `PeerImp` relay, then validate with multi-node integration tests and performance benchmarks.
-- **Weeks 6-8 (tasks 11-12)**: Consensus deep-dive -- instrument consensus rounds and phases, then run full integration testing across all instrumented paths.
-- **Week 9 (tasks 13-14)**: Go-live -- deploy to production with sampling/alerting configured, and deliver documentation and operator training.
-- **Arrow chain (t1 → ... → t14)**: Strict sequential dependency; each task's output is a prerequisite for the next.

-**Reading the diagram:**
-
-- **Budget Constraints? (Yes)**: Leads to open-source options. If you already run Grafana or Elastic, pick the matching backend; otherwise default to Grafana Tempo.
-- **Budget Constraints? (No) → Prefer SaaS?**: If you want a managed service, choose between Datadog (enterprise support) and Honeycomb (developer-focused). If not, fall back to open-source.
-- **Terminal nodes (Tempo / Elastic / Honeycomb / Datadog)**: Each represents a concrete backend choice, all of which feed into the same final step.
-- **Configure Collector**: Regardless of backend, you always finish by configuring the OTel Collector to export to your chosen destination.

-
-**Reading the diagram:**
-
-- **Validator / Stock Nodes**: All xrpld nodes emit trace data via OTLP. Validators and stock nodes are grouped separately because they may reside in different network zones.
-- **Collector Cluster (DC1, DC2)**: Regional collectors receive OTLP from nodes in their datacenter, apply processing (sampling, enrichment), and fan out to multiple backends. Enrichment includes deployment-tier tagging: each collector stamps `deployment.environment` and (as a fallback) `xrpl.network.type` so one Grafana stack can filter data from many collectors by tier.
-- **Storage Backends**: Tempo and Elastic provide queryable trace storage; S3/GCS Archive provides long-term cold storage for compliance or post-incident analysis.
-- **Grafana Dashboards**: The single visualization layer that queries both Tempo and Elastic, giving operators a unified view of all traces.
-- **Data flow direction**: Nodes → Collectors → Storage → Grafana. Each arrow represents a network hop; minimizing collector-to-backend hops reduces latency.
-
-> **Note**: Production deployments should use multiple collector instances behind a load balancer for high availability. The diagram shows a simplified single-collector topology for clarity.

-## 7.4 Architecture Considerations
-
-### 7.4.1 Collector Placement
-
-| Strategy      | Description          | Pros                     | Cons                    |
-| ------------- | -------------------- | ------------------------ | ----------------------- |
-| **Sidecar**   | Collector per node   | Isolation, simple config | Resource overhead       |
-| **DaemonSet** | Collector per host   | Shared resources         | Complexity              |
-| **Gateway**   | Central collector(s) | Centralized processing   | Single point of failure |
-
-**Recommendation**: Use **Gateway** pattern with regional collectors for xrpld networks:
-
-- One collector cluster per datacenter/region
-- Tail-based sampling at collector level
-- Multiple export destinations for redundancy
-
-### 7.4.2 Sampling Strategy
-
-```mermaid
-flowchart LR
-    subgraph head["Head Sampling (Node)"]
-        hs[Node-level head sampling<br/>fixed at 100%<br/>not configurable]
-    end
-
-    subgraph tail["Tail Sampling (Collector)"]
-        ts1[Keep all errors]
-        ts2[Keep slow >5s]
-        ts3[Keep 10% rest]
-    end
-
-    head --> tail
-
-    ts1 --> final[Final Traces]
-    ts2 --> final
-    ts3 --> final
-
-    style head fill:#0d47a1,stroke:#082f6a,color:#fff
-    style tail fill:#1b5e20,stroke:#0d3d14,color:#fff
-    style hs fill:#0d47a1,stroke:#082f6a,color:#fff
-    style ts1 fill:#1b5e20,stroke:#0d3d14,color:#fff
-    style ts2 fill:#1b5e20,stroke:#0d3d14,color:#fff
-    style ts3 fill:#1b5e20,stroke:#0d3d14,color:#fff
-    style final fill:#bf360c,stroke:#8c2809,color:#fff
-```
-
-**Reading the diagram:**
-
-- **Head Sampling (Node)**: xrpld pins head sampling at 100% (sample everything) and does not expose a configurable ratio. This is intentional: a per-node ratio would let different nodes make divergent keep/drop decisions for the same distributed trace, producing broken/partial traces. xrpld uses a `ParentBased` sampler so spans inheriting a remote parent honor the upstream decision. Volume reduction is delegated to the collector's tail sampling.
-- **Tail Sampling (Collector)**: The second filter -- the collector inspects completed traces and applies rules: keep all errors, keep anything slower than 5 seconds, and keep 10% of the remainder.
-- **Arrow head → tail**: All head-sampled traces flow to the collector, where tail sampling further reduces volume while preserving the most valuable data.
-- **Final Traces**: The output after both sampling stages; this is what gets stored and queried. The two-stage approach balances cost with debuggability.
-
-### 7.4.3 Data Retention
-
-| Environment | Hot Storage | Warm Storage | Cold Archive |
-| ----------- | ----------- | ------------ | ------------ |
-| Development | 24 hours    | N/A          | N/A          |
-| Staging     | 7 days      | N/A          | N/A          |
-| Production  | 7 days      | 30 days      | many years   |
-
----
-
-## 7.5 Integration Checklist
-
-- [ ] Choose primary backend (Tempo recommended for cost/features)
-- [ ] Deploy collector cluster with high availability
-- [ ] Configure tail-based sampling for error/latency traces
-- [ ] Set up Grafana dashboards for trace visualization
-- [ ] Configure alerts for trace anomalies
-- [ ] Establish data retention policies
-- [ ] Test trace correlation with logs and metrics

-## 7.6 Grafana Dashboard Examples
-
-Pre-built dashboards for xrpld observability.
-
-### 7.6.1 Consensus Health Dashboard
-
-A Tempo-backed dashboard (uid `xrpld-consensus-health`) with four panels, all driven by TraceQL:
-
-- **Consensus Round Duration** (timeseries, ms): average `consensus.round` span duration per node instance, with yellow/red thresholds at 4s/5s.
-- **Phase Duration Breakdown** (barchart): average duration of `consensus.phase.*` spans grouped by span name.
-- **Proposers per Round** (stat): average of the `span.proposers` attribute on `consensus.round` spans.
-- **Recent Slow Rounds (>5s)** (table): `consensus.round` spans filtered to `duration > 5s`.
-
-Each panel's TraceQL query is described inline in its bullet above.
-
-### 7.6.2 Node Overview Dashboard
-
-A Tempo-backed dashboard (uid `xrpld-node-overview`) with four panels:
-
-- **Active Nodes** (stat): count of distinct `resource.service.instance.id` values seen for the `xrpld` service.
-- **Total Transactions (1h)** (stat): count of `tx.receive` spans.
-- **Error Rate** (gauge, percent): ratio of `status = error` spans to all spans, with yellow/red thresholds at 1%/5%.
-- **Service Map** (nodeGraph): Tempo-generated service dependency graph.
-
-### 7.6.3 Alert Rules
-
-Grafana provisions three TraceQL-based alert rules (group `xrpld-tracing-alerts`, evaluated every 1m) against the Tempo datasource:
-
-- **Consensus Round Slow** (warning, `for: 5m`): fires when average `consensus.round` duration exceeds 5s.
-
-  ```
-  {resource.service.name="xrpld" && name="consensus.round"} | avg(duration) > 5s
-  ```
-
-- **RPC Error Rate Spike** (critical, `for: 2m`): fires when the error rate across `rpc.command.*` spans exceeds 5%. Error _rate_ is a ratio, so it must divide the error-span rate by the total-span rate — a single TraceQL `rate()` returns spans/second, not a percentage, and would fire on traffic volume alone. This uses span metrics emitted by the collector's `spanmetrics` connector (Prometheus datasource), not a TraceQL query:
-
-  ```
-  sum(rate(traces_spanmetrics_calls_total{service_name="xrpld", span_name=~"rpc.command.*", status_code="STATUS_CODE_ERROR"}[5m]))
-  /
-  sum(rate(traces_spanmetrics_calls_total{service_name="xrpld", span_name=~"rpc.command.*"}[5m]))
-  > 0.05
-  ```
-
-- **Transaction Throughput Drop** (warning, `for: 10m`): fires when the `tx.receive` span rate falls below 10/s.
-
-  ```
-  {resource.service.name="xrpld" && name="tx.receive"} | rate() < 10
-  ```
-
-> **Note**: The Consensus Round Slow and Transaction Throughput Drop rules use TraceQL aggregates (`avg(duration)`, `rate()`), which require Tempo 2.3+ with TraceQL metrics enabled. Verify aggregate query support in your Tempo version before provisioning. The RPC Error Rate Spike rule instead queries Prometheus span metrics (collector `spanmetrics` connector), so it needs that connector enabled in the collector pipeline.

-
-**Reading the diagram:**
-
-- **xrpld Node (three sources)**: A single node emits three independent data streams -- OpenTelemetry spans, PerfLog JSON logs, and Beast Insight StatsD metrics.
-- **Data Collection layer**: Each stream has its own collector -- OTel Collector for spans, Promtail/Fluentd for logs, and a StatsD exporter for metrics. They operate independently.
-- **Storage layer (Tempo, Loki, Prometheus)**: Each data type lands in a purpose-built store optimized for its query patterns (trace search, log grep, metric aggregation).
-- **Grafana Correlation Panel**: The key integration point -- Grafana queries all three stores and links them via shared fields (`trace_id`, `tx_hash`, `ledger_seq`), enabling a single-pane debugging experience.
-
-### 7.7.2 Correlation Fields
-
-| Source      | Field               | Link To       | Purpose                    |
-| ----------- | ------------------- | ------------- | -------------------------- |
-| **Trace**   | `trace_id`          | Logs          | Find log entries for trace |
-| **Trace**   | `tx_hash`           | Logs, Metrics | Find TX-related data       |
-| **Trace**   | `ledger_seq`        | Logs          | Find ledger-related logs   |
-| **PerfLog** | `trace_id` (new)    | Traces        | Jump to trace from log     |
-| **PerfLog** | `ledger_seq`        | Traces        | Find consensus trace       |
-| **Insight** | `exemplar.trace_id` | Traces        | Jump from metric spike     |
-
-### 7.7.3 Example: Debugging a Slow Transaction
-
-**Step 1: Find the trace**
-
-```
-# In Grafana Explore with Tempo
-{resource.service.name="xrpld" && span.tx_hash="ABC123..."}
-```
-
-**Step 2: Get the trace_id from the trace view**
-
-```
-Trace ID: 4bf92f3577b34da6a3ce929d0e0e4736
-```
-
-**Step 3: Find related PerfLog entries**
-
-```
-# In Grafana Explore with Loki
-{job="xrpld"} |= "4bf92f3577b34da6a3ce929d0e0e4736"
-```
-
-**Step 4: Check Insight metrics for the time window**
-
-```
-# In Grafana with Prometheus
-rate(xrpld_tx_applied_total[1m])
-  @ timestamp_from_trace
-```
-
-### 7.7.4 Unified Dashboard Example
-
-A single dashboard (uid `xrpld-unified`) that ties traces, metrics, and logs together across the Tempo, Prometheus, and Loki datasources:
-
-- **Transaction Latency (Traces)** (timeseries, Tempo): `histogram_over_time(duration)` of `tx.receive` spans.
-- **Transaction Rate (Metrics)** (timeseries, Prometheus): `rate(xrpld_tx_received_total[5m])` per instance, with a data link that opens the matching `tx.receive` traces in Tempo.
-- **Recent Logs** (logs, Loki): `{job="xrpld"} | json`.
-- **Trace Search** (table, Tempo): all `xrpld` traces, with per-row data links on `traceID` that jump to the trace in Tempo and to the correlated logs in Loki (`{job="xrpld"} |= "<traceID>"`).
-
-The cross-datasource data links are what make this a single-pane debugging view; the correlation fields they rely on are listed in section 7.7.2.

-**Reading the diagram:**
-
-- **rpc.request (blue, top)**: The entry point — every traced transaction starts as an RPC call; this root span is the parent of all downstream work.
-- **tx.validate and pathfind.request (green/teal, first fork)**: The RPC request fans out into transaction validation and, for cross-currency payments, a PathFinding branch (`pathfind.request` -> `pathfind.compute`).
-- **tx.relay -> Peer Spans (teal, middle)**: After validation, the transaction is relayed to peers A, B, and C in parallel; each `peer.send` is a sibling child span showing fan-out across the network.
-- **context propagation (dashed arrow)**: The dotted line from `peer.send Peer A` to `consensus.round` represents the trace context crossing a node boundary — the receiving validator picks up the same `trace_id` and continues the trace.
-- **consensus.round -> tx.apply -> TxQ Spans (green, lower)**: Once consensus accepts the transaction, it is applied to the ledger; the TxQ spans (`txq.enqueue`, `txq.apply`, `fee.escalate`) capture queue depth and fee escalation behavior.
-- **Validator Spans (purple, detached)**: `validator.list.fetch` and `validator.manifest` are independent workflows for UNL management — they run on their own traces and are linked to consensus via Span Links, not parent-child relationships.

-## 0. Tracing Fundamentals
-
-This document introduces distributed tracing concepts for readers unfamiliar with the domain. It covers what traces and spans are, how parent-child and follows-from relationships model causality, how context propagates across service boundaries, and how sampling controls data volume. It also maps these concepts to xrpld-specific scenarios like transaction relay and consensus.
-
-➡️ **[Read Tracing Fundamentals](./00-tracing-fundamentals.md)**
-
----
-
-## 1. Architecture Analysis
-
-> **WS** = WebSocket | **TxQ** = Transaction Queue
-
-The xrpld node consists of several key components that require instrumentation for comprehensive distributed tracing. The main areas include the RPC server (HTTP/WebSocket), Overlay P2P network, Consensus mechanism (RCLConsensus), JobQueue for async task execution, PathFinding, Transaction Queue (TxQ), fee escalation (LoadManager), ledger acquisition, validator management, and existing observability infrastructure (PerfLog, Insight/StatsD, Journal logging).
-
-Key trace points span across transaction submission via RPC, peer-to-peer message propagation, consensus round execution, ledger building, path computation, transaction queue behavior, fee escalation, and validator health. The implementation prioritizes high-value, low-risk components first: RPC handlers provide immediate value with minimal risk, while consensus tracing requires careful implementation to avoid timing impacts.

-
----
-
-## 2. Design Decisions
-
-> **OTLP** = OpenTelemetry Protocol | **CNCF** = Cloud Native Computing Foundation
-
-The OpenTelemetry C++ SDK is selected for its CNCF backing, active development, and native performance characteristics. Traces are exported via OTLP/HTTP to an OpenTelemetry Collector, which provides flexible routing and sampling. OTLP/gRPC is planned future work (see design decisions §2.2.2).
-
-Span naming follows a hierarchical `<component>.<operation>` convention (e.g., `rpc.submit`, `tx.relay`, `consensus.round`). Context propagation uses W3C Trace Context headers for HTTP and embedded Protocol Buffer fields for P2P messages. The implementation coexists with existing PerfLog and Insight observability systems through correlation IDs.
-
-**Data Collection & Privacy**: Telemetry collects only operational metadata (timing, counts, hashes) — never sensitive content (private keys, balances, amounts, raw payloads). Account addresses are public ledger identifiers and are emitted raw; there is no redaction setting. Trace volume is reduced, where wanted, by collector-side sampling. Node operators retain full control over telemetry configuration.
-
-➡️ **[Read full Design Decisions](./02-design-decisions.md)**
-
----
-
-## 3. Implementation Strategy
-
-The telemetry code is organized under `include/xrpl/telemetry/` for headers and `src/libxrpl/telemetry/` for implementation. Key principles include RAII-based span management via `SpanGuard` (with `discard()` for dropping unwanted spans), a `FilteringSpanProcessor` that intercepts `OnEnd()` to prevent discarded spans from entering the export pipeline, conditional compilation with `XRPL_ENABLE_TELEMETRY`, and minimal runtime overhead through batch processing and efficient sampling.
-
-Performance optimization strategies include head sampling fixed at 100% (intentionally not configurable, so trace keep/drop decisions stay coherent across nodes), tail-based sampling at the collector for errors and slow traces to reduce volume, batch export to reduce network overhead, and conditional instrumentation that compiles to no-ops when disabled.
-
-➡️ **[Read full Implementation Strategy](./03-implementation-strategy.md)**
-
----
-
-## 5. Configuration Reference
-
-> **OTLP** = OpenTelemetry Protocol | **APM** = Application Performance Monitoring
-
-Configuration is handled through the `[telemetry]` section in `xrpld.cfg` with options for enabling/disabling, exporter selection, endpoint configuration, and component-level filtering. Head sampling is fixed at 1.0 (not operator-configurable); volume reduction is done by tail sampling in the collector. CMake integration includes a `XRPL_ENABLE_TELEMETRY` option for compile-time control.
-
-OpenTelemetry Collector configurations are provided for development and production (with tail-based sampling, Tempo, and Elastic APM). Docker Compose examples enable quick local development environment setup.

-## 6. Implementation Phases
-
-The implementation spans 9 weeks across 5 phases:
-
-| Phase | Duration  | Focus               | Key Deliverables                                    |
-| ----- | --------- | ------------------- | --------------------------------------------------- |
-| 1     | Weeks 1-2 | Core Infrastructure | SDK integration, Telemetry interface, Configuration |
-| 2     | Weeks 3-4 | RPC Tracing         | HTTP context extraction, Handler instrumentation    |
-| 3     | Weeks 5-6 | Transaction Tracing | Protocol Buffer context, Relay propagation          |
-| 4     | Weeks 7-8 | Consensus Tracing   | Round spans, Proposal/validation tracing            |
-| 5     | Week 9    | Documentation       | Runbook, Dashboards, Training                       |

-
-## 7. Observability Backends
-
-> **APM** = Application Performance Monitoring | **GCS** = Google Cloud Storage
-
-Grafana Tempo is recommended for all environments due to its cost-effectiveness and Grafana integration, while Elastic APM is ideal for organizations with existing Elastic infrastructure.
-
-The recommended production architecture uses a gateway collector pattern with regional collectors performing tail-based sampling, routing traces to multiple backends (Tempo for primary storage, Elastic for log correlation, S3/GCS for long-term archive).

-## Task 2.1: W3C Trace Context HTTP Header Extraction
-
-**Status**: DEFERRED → Phase 3
-
-**Reason**: W3C context propagation (`traceparent`/`tracestate` headers) requires a consumer — in Phase 2, RPC spans are entirely local to the node. Phase 3 introduces cross-node transaction tracing via protobuf context propagation, which is the first use case for extracted trace context. Implementing it here without a consumer would be dead code.
-
-**Implemented in**: `pratik/otel-phase3-tx-tracing` — `TraceContextPropagator.h/.cpp`
-
----
-
-## Task 2.2: Per-Category Span Creation
-
-**Status**: COMPLETE (superseded by Phase 1c design)
-
-**Original plan**: Add `XRPL_TRACE_PEER` and `XRPL_TRACE_LEDGER` macros.
-
-**Actual implementation**: Phase 1c replaced all tracing macros with the `SpanGuard::span(TraceCategory, prefix, name)` factory pattern. The `TraceCategory` enum (`Rpc`, `Transactions`, `Consensus`, `Peer`, `Ledger`) serves the same conditional-creation purpose without macros. No separate task needed — the factory already supports all categories.
-
----
-
-## Task 2.3: Add shouldTraceLedger() to Telemetry Interface
-
-**Objective**: The `Setup` struct has a `traceLedger` field but there's no corresponding virtual method. Add it for interface completeness.
-
-**What to do**:
-
-- Edit `include/xrpl/telemetry/Telemetry.h`:
-  - Add `virtual bool shouldTraceLedger() const = 0;`
-
-- Update all implementations:
-  - `src/libxrpl/telemetry/Telemetry.cpp` (TelemetryImpl, NullTelemetryOtel)
-  - `src/libxrpl/telemetry/NullTelemetry.cpp` (NullTelemetry)
-
-**Key modified files**:
-
-- `include/xrpl/telemetry/Telemetry.h`
-- `src/libxrpl/telemetry/Telemetry.cpp`
-- `src/libxrpl/telemetry/NullTelemetry.cpp`
-
----
-
-## Task 2.4: Unit Tests for Core Telemetry Infrastructure
-
-**Status**: COMPLETE
-
-**Objective**: Add unit tests for the core telemetry abstractions to validate correctness and catch regressions.
-
-**Implemented**:
-
-- `src/tests/libxrpl/telemetry/TelemetryConfig.cpp`:
-  - Test Setup defaults (all fields have correct initial values)
-  - Test `makeTelemetrySetup` config parser (empty section, full section, edge cases)
-  - Test `samplingRatio` clamping (values outside 0.0-1.0)
-
-- `src/tests/libxrpl/telemetry/SpanGuardFactory.cpp`:
-  - Test null guard methods are safe (setAttribute, setOk, setError, addEvent on null)
-  - Test category span returns null when telemetry disabled
-  - Test child/linked span null when no parent context
-  - Test move construction transfers ownership
-  - Test recordException safe on null guard
-  - Test discard() safe on null guard
-
-- `src/tests/libxrpl/telemetry/main.cpp` — GTest runner
-- `src/tests/libxrpl/CMakeLists.txt` — test target with optional OTel linking
-
----
-
-## Task 2.5: Enhance RPC Span Attributes
-
-**Status**: DEFERRED (low priority)
-
-**Reason**: The high-value attributes (`command`, `version`, `role`, `status`) are already set by Phase 1c. The remaining HTTP transport-level attributes (`http.method`, `net.peer.ip`, `http.status_code`) provide limited additional insight since:
-
-- `http.method` is always POST for JSON-RPC
-- `net.peer.ip` is debug-level info available in logs
-- `duration_ms` is redundant with span duration (OTel captures start/end time natively)
-
-These can be added later if dashboard queries specifically need them. The node health attributes (Task 2.8) provide far more operational value and were prioritized instead.
-
----
-
-## Task 2.6: Build Verification and Performance Baseline
-
-**Objective**: Verify the build succeeds with and without telemetry, and establish a performance baseline.
-
-**What to do**:
-
-1. Build with `telemetry=ON` and verify no compilation errors
-2. Build with `telemetry=OFF` and verify no regressions
-3. Run existing unit tests to verify no breakage
-4. Document any build issues in lessons.md
-
-**Verification Checklist**:
-
-- [ ] `conan install . --build=missing -o telemetry=True` succeeds
-- [ ] `cmake --preset default -Dtelemetry=ON` configures correctly
-- [ ] Build succeeds with telemetry ON
-- [ ] Build succeeds with telemetry OFF
-- [ ] Existing tests pass with telemetry ON
-- [ ] Existing tests pass with telemetry OFF
-
----
-
-## Task 2.8: RPC Span Attribute Enrichment — Node Health Context
-
-**Status**: DROPPED.
-
-Node health (`amendment_blocked`, `server_state`) is not part of the telemetry surface. Operators consume the same data via the existing `server_info` / `server_state` RPC commands, so duplicating it on traces adds storage and cardinality cost without new value. The OTel C++ SDK 1.18.0 also does not support runtime updates to the resource, ruling out resource-level emission of these dynamic-by-nature flags.
-
----
-
-## Task 2.9: PathFind RPC Instrumentation
-
-**Status**: COMPLETE
-
-**Objective**: Trace the path_find and ripple_path_find RPC handlers to capture request latency and computation cost.
-
-**Spans added**:
-
-- `pathfind.request` — wraps `doPathFind()` and `doRipplePathFind()` RPC handlers
-- `pathfind.compute` — wraps `PathRequest::doUpdate()` (`pathfind_fast` attr)
-- `pathfind.update_all` — wraps `PathRequestManager::updateAll()` on ledger close (`pathfind_ledger_index`, `pathfind_num_requests` attrs; emitted only when active subscriptions exist)
-- `pathfind.discover` — wraps the entire per-source-asset loop in `PathRequest::findPaths()` (`pathfind_search_level`, `pathfind_num_paths` attrs). One span per RPC call instead of N (one per source asset). Trade-off: per-asset breakdown is lost; storage and cardinality bounded.
-
-**Attribute namespacing**: All pathfind attributes use the `pathfind_*` underscore form per the Phase 1c naming-spec rule 5.
-
-**New file**: `src/xrpld/rpc/detail/PathFindSpanNames.h`
-
-**Modified files**:
-
-- `src/xrpld/rpc/handlers/orderbook/PathFind.cpp`
-- `src/xrpld/rpc/handlers/orderbook/RipplePathFind.cpp`
-- `src/xrpld/rpc/detail/PathRequest.cpp`
-- `src/xrpld/rpc/detail/PathRequestManager.cpp`
-- `src/xrpld/rpc/detail/Pathfinder.cpp`

-
-## Task 2.10: RPC and PathFind Span Attribute Gap Fill
-
-**Status**: COMPLETE
-
-**Objective**: Wire up workflow-identifying attributes that enable filtering and grouping traces by request characteristics without drilling into child spans.
-
-**Attributes added**:

-## Task 3.1: Define TraceContext Protocol Buffer Message
-
-**Objective**: Add trace context fields to the P2P protocol messages so trace IDs can propagate across nodes.
-
-**What to do**:
-
-- Edit `include/xrpl/proto/xrpl.proto` (or `src/xrpld/proto/ripple.proto`, wherever the proto is):
-  - Add `TraceContext` message definition:
-    ```protobuf
-    message TraceContext {
-        bytes trace_id = 1;      // 16-byte trace identifier
-        bytes span_id = 2;       // 8-byte span identifier
-        uint32 trace_flags = 3;  // bit 0 = sampled
-        string trace_state = 4;  // W3C tracestate value
-    }
-    ```
-  - Add `optional TraceContext trace_context = 1001;` to:
-    - `TMTransaction`
-    - `TMProposeSet` (for Phase 4 use)
-    - `TMValidation` (for Phase 4 use)
-  - Use high field numbers (1001+) to avoid conflicts with existing fields

-## Task 3.2: Implement Protobuf Context Serialization
-
-**Objective**: Create utilities to serialize/deserialize OTel trace context to/from protobuf `TraceContext` messages.
-
-**What to do**:
-
-- Create `include/xrpl/telemetry/TraceContextPropagator.h` (extend from Phase 2 if exists, or add protobuf methods):
-  - Add protobuf-specific methods:
-    - `static Context extractFromProtobuf(protocol::TraceContext const& proto)` — reconstruct OTel context from protobuf fields
-    - `static void injectToProtobuf(Context const& ctx, protocol::TraceContext& proto)` — serialize current span context into protobuf fields
-  - Both methods guard behind `#ifdef XRPL_ENABLE_TELEMETRY`
-
-- Create/extend `src/libxrpl/telemetry/TraceContextPropagator.cpp`:
-  - Implement extraction: read trace_id (16 bytes), span_id (8 bytes), trace_flags from protobuf, construct `SpanContext`, wrap in `Context`
-  - Implement injection: get current span from context, serialize its TraceId, SpanId, and TraceFlags into protobuf fields

-## Task 3.3: Instrument PeerImp Transaction Handling
-
-**Objective**: Add trace spans to the peer-level transaction receive and relay path.
-
-**What to do**:
-
-- Edit `src/xrpld/overlay/detail/PeerImp.cpp`:
-  - In `onMessage(TMTransaction)` / `handleTransaction()`:
-    - Extract parent trace context from incoming `TMTransaction::trace_context` field (if present)
-    - Create `tx.receive` span as child of extracted context (or new root if none)
-    - Set attributes: `tx_hash`, `peer_id`, `tx_status`
-    - Create the span only after `HashRouter::shouldProcess()` accepts, so a dropped duplicate produces no span
-    - Wrap validation call with child span `tx.validate`
-    - Wrap relay with `tx.relay` span
-  - When relaying to peers:
-    - Inject current trace context into outgoing `TMTransaction::trace_context`
-    - Set `relay_count` attribute
-
-- Use `SpanGuard::span(TraceCategory::Transactions, "tx", "receive")` factory
-  (Phase 1c replaced macros with the SpanGuard factory pattern)
-
-> **Note**: The `tx.receive` guard is `.detached()` before being moved into the
-> `RcvCheckTx` job so its Scope is popped on the peer thread, not leaked to the
-> worker (else later peer messages would inherit this transaction's trace).

-## Task 3.4: Instrument NetworkOPs Transaction Processing
-
-**Objective**: Trace the transaction processing pipeline in NetworkOPs, covering both sync and async paths.
-
-**What to do**:
-
-- Edit `src/xrpld/app/misc/NetworkOPs.cpp`:
-  - In `processTransaction()`:
-    - Create `tx.process` span
-    - Set attributes: `tx_hash`, `tx_type`, `local` (whether from RPC or peer)
-    - Record whether sync or async path is taken
-    - `.detached()` the guard before storing it in `TransactionStatus::span`,
-      since it is applied on a batch worker thread — this pops the Scope on the
-      origin thread and stops later work inheriting this transaction's trace
-
-  - In `doTransactionAsync()`:
-    - Capture parent context before queuing
-    - Create `tx.queue` span with queue depth attribute
-    - Add event when transaction is dequeued for processing
-
-  - In `doTransactionSync()`:
-    - Create `tx.process_sync` span
-    - Record result (applied, queued, rejected)

-## Task 3.5: Instrument HashRouter for Dedup Visibility
-
-**Objective**: Make transaction deduplication visible in traces by recording HashRouter decisions as span attributes/events.
-
-**What to do**:
-
-- Edit `src/xrpld/overlay/detail/PeerImp.cpp` (in handleTransaction):
-  - After calling `HashRouter::shouldProcess()` or `addSuppressionPeer()`:
-    - Start the span here, not before, so only transactions this node will process are traced
-    - Record `tx_flags` showing current HashRouter state (SAVED, TRUSTED, etc.)
-    - Add `tx.first_seen` or `tx.duplicate` event
-
-- This is NOT a modification to HashRouter itself — just recording its decisions as span attributes in the existing PeerImp instrumentation from Task 3.3.
-
-**Key modified files**:
-
-- `src/xrpld/overlay/detail/PeerImp.cpp` (same changes as 3.3, logically grouped)

-## Task 3.6: Context Propagation in Transaction Relay
-
-**Status**: COMPLETE (transaction relay). Consensus proposal/validation
-propagation is deferred to Phase 4 — see "Planned (Phase 4)" below.
-
-**Objective**: Ensure trace context flows correctly when transactions are relayed between peers, creating linked spans across nodes.
-
-**What was done**:
-
-- **TX send side**: `NetworkOPs::apply()` now injects the tx.process span's trace
-  context into the outgoing `TMTransaction` protobuf before relay, using
-  `telemetry::injectSpanContext()`. The receiving node's `txReceiveSpan()` (already
-  wired in PeerImp) extracts the parent span_id and creates the tx.receive span
-  as a child of the sender's tx.process span.
-
-- **Edge cases**: Missing trace context (older peers) degrades gracefully to
-  standalone spans. Invalid/corrupted context is treated as absent. Trace
-  flags are propagated and respected.
-
-**New infrastructure**:
-
-- `SpanGuard::getTraceBytes()` — extracts raw trace_id/span_id/trace_flags
-  from a span without exposing OTel types. Safe to call from any thread.
-- `PropagationHelpers.h` — `injectSpanContext(SpanGuard&, proto)` bridge
-  between SpanGuard and protobuf TraceContext.
-- `TraceContextPropagator.h` — `injectToProtobuf(ctx, proto)` for
-  same-thread injection via OTel RuntimeContext.
-
-**Key modified files**:
-
-- `src/xrpld/app/misc/NetworkOPs.cpp` — tx relay injection
-- `include/xrpl/telemetry/SpanGuard.h` — `TraceBytes` struct, `getTraceBytes()`
-- `src/libxrpl/telemetry/SpanGuard.cpp` — `getTraceBytes()` implementation
-- `src/xrpld/telemetry/PropagationHelpers.h` — inject helpers (new file)
-
-**Planned (Phase 4 — not in this PR)**:
-
-The consensus proposal/validation propagation below is Phase 4 scope and is
-not implemented on this branch. It is listed here only to record the intended
-design.
-
-- **Proposal send/receive**: `RCLConsensus::Adaptor::propose()` injects the
-  current thread's active span context into the `TMProposeSet` protobuf via
-  `telemetry::injectToProtobuf()`. PeerImp creates a
-  `consensus.proposal.receive` span that extracts the sender's trace context
-  as parent (via `ConsensusReceiveTracing.h`).
-
-- **Validation send/receive**: `RCLConsensus::Adaptor::validate()` injects
-  the current thread's active span context into the `TMValidation` protobuf.
-  PeerImp creates a `consensus.validation.receive` span that extracts the
-  sender's trace context as parent.
-
-- Planned files: `src/xrpld/app/consensus/RCLConsensus.cpp` (send injection),
-  `src/xrpld/overlay/detail/PeerImp.cpp` (receive spans),
-  `src/xrpld/telemetry/ConsensusReceiveTracing.h` (receive span helpers,
-  new file).

-## Task 3.7: Build Verification and Testing
-
-**Objective**: Verify all Phase 3 changes compile and work correctly.
-
-**What to do**:
-
-1. Build with `telemetry=ON` — verify no compilation errors
-2. Build with `telemetry=OFF` — verify no regressions
-3. Run existing unit tests
-4. Verify protobuf regeneration produces correct C++ code
-5. Document any issues encountered
-
-**Verification Checklist**:
-
-- [ ] Protobuf changes generate valid C++
-- [ ] Build succeeds with telemetry ON
-- [ ] Build succeeds with telemetry OFF
-- [ ] Existing tests pass
-- [ ] No undefined symbols from new telemetry calls

-## Task 3.8: Transaction Span Peer Version Attribute
-
-> **Source**: [External Dashboard Parity](../docs/superpowers/specs/2026-03-30-external-dashboard-parity-design.md) — adds peer version context inspired by the community [xrpl-validator-dashboard](https://github.com/realgrapedrop/xrpl-validator-dashboard).
->
-> **Upstream**: Phase 2 (RPC span infrastructure must exist).
-> **Downstream**: Phase 10 (validation checks for this attribute).
-
-**Objective**: Add the relaying peer's xrpld version to `tx.receive` spans so operators can correlate transaction issues with peer version mismatches during network upgrades.
-
-**What to do**:
-
-- Edit `src/xrpld/overlay/detail/PeerImp.cpp`:
-  - In the `tx.receive` span block (after existing `peer_id` setAttribute call):
-    - Add `peer_version` (string) — from `this->getVersion()`
-    - Only set if `getVersion()` returns a non-empty string (avoid empty-string attributes)
-
-**New span attribute**:
-
-| Attribute      | Type   | Source               | Example         |
-| -------------- | ------ | -------------------- | --------------- |
-| `peer_version` | string | `peer->getVersion()` | `"xrpld-2.4.0"` |
-
-**Rationale**: Transaction relay is where version mismatches cause subtle serialization or validation bugs. Tracing "this tx came from a v2.3.0 peer" helps diagnose compatibility issues. The community dashboard tracks peer versions externally; this brings version awareness into the trace itself.
-
-**Key modified files**:
-
-- `src/xrpld/overlay/detail/PeerImp.cpp`
-
-**Exit Criteria**:
-
-- [ ] `tx.receive` spans carry `peer_version` attribute with a non-empty version string
-- [ ] Attribute is omitted (not set to empty string) when `getVersion()` returns empty
-- [ ] Attribute visible in Jaeger span detail view

-## Task 3.9: Deterministic Transaction Trace ID
-
-> **Upstream**: Task 3.2 (protobuf serialization), Task 3.3 (PeerImp span exists).
-> **Downstream**: Phase 10 (workload validation can query by tx hash directly).
-> **Pattern**: Mirrors the consensus deterministic trace ID in Phase 4a
-> (`createDeterministicContext` in `RCLConsensus.cpp`), adapted for transactions.
-
-**Objective**: Derive the trace_id for transaction spans deterministically from the
-transaction hash so that all nodes handling the same transaction independently produce
-spans under the same trace_id — regardless of whether protobuf context propagation
-succeeds.
-
-**Why**: The current approach creates spans with random trace_ids and relies entirely
-on protobuf `TraceContext` propagation to link them. If any hop in the relay chain
-drops the context (older peers, message corruption, mixed-version networks), the trace
-splits and downstream spans become impossible to find. With deterministic trace_ids,
-correlation is guaranteed because every node derives the same trace_id from the same
-`txID`.
-
-**Approach — deterministic trace_id + protobuf span_id propagation**:
-
-1. Derive `trace_id = txHash[0:16]` (first 16 bytes of the 32-byte transaction hash).
-2. Generate a random 8-byte `span_id` per node (each node's span is unique within
-   the shared trace).
-3. Create the span under this deterministic context as parent.
-4. **Additionally**, if protobuf `TraceContext` is present in the incoming
-   `TMTransaction` message, extract the sender's `span_id` and use it as the span's
-   parent — this preserves parent-child ordering in the trace tree.
-5. If protobuf context is absent (older peer, first hop), the span still has the
-   correct deterministic `trace_id` — it appears as a sibling root in the same trace
-   rather than being lost.
-
-This gives the best of both worlds: guaranteed cross-node correlation via deterministic
-`trace_id`, plus parent-child relay ordering via protobuf `span_id` when available.
-
-**What to do**:
-
-- Create `createDeterministicTxContext(uint256 const& txHash)` utility function:
-  - Location: shared header or file-local in `PeerImp.cpp` and `NetworkOPs.cpp`
-    (or a shared telemetry utility if both need it).
-  - Pattern: identical to `createDeterministicContext(uint256 const& ledgerId)` in
-    `RCLConsensus.cpp` — take `txHash[0:16]` as trace_id, random span_id via
-    `default_prng()`, sampled flag set, `remote=false`.
-  - Guard behind `#ifdef XRPL_ENABLE_TELEMETRY`.
-
-  ```cpp
-  opentelemetry::context::Context
-  createDeterministicTxContext(uint256 const& txHash)
-  {
-      namespace trace = opentelemetry::trace;
-
-      // First 16 bytes of the 32-byte tx hash as trace ID.
-      trace::TraceId traceId(
-          opentelemetry::nostd::span<uint8_t const, 16>(txHash.data(), 16));
-
-      // Random span_id so each node's span is unique within the trace.
-      uint8_t spanIdBytes[8];
-      auto const rval = default_prng()();
-      std::memcpy(spanIdBytes, &rval, sizeof(spanIdBytes));
-      trace::SpanId spanId(
-          opentelemetry::nostd::span<uint8_t const, 8>(spanIdBytes, 8));
-
-      trace::SpanContext syntheticCtx(
-          traceId, spanId, trace::TraceFlags(1), /* remote = */ false);
-
-      return opentelemetry::context::Context{}.SetValue(
-          trace::kSpanKey,
-          opentelemetry::nostd::shared_ptr<trace::Span>(
-              new trace::DefaultSpan(syntheticCtx)));
-  }
-  ```
-
-- Edit `src/xrpld/overlay/detail/PeerImp.cpp` — restructure `handleTransaction()`:
-  - **Move span creation after deserialization** (txID must be known first):
-    1. Deserialize `STTx` and get `txID` (existing code at line ~1382).
-    2. Create deterministic parent context: `auto detCtx = createDeterministicTxContext(txID)`.
-    3. If `m->has_trace_context()`: extract protobuf context via `extractFromProtobuf()`,
-       **combine** with deterministic trace_id — use the protobuf span_id as parent
-       to preserve relay ordering, but override trace_id with the deterministic one.
-    4. If no protobuf context: create span under `detCtx` directly.
-    5. Set all existing attributes (`hash`, `peerId`, `peerVersion`, etc.).
-
-  - **Combining deterministic trace_id with protobuf parent span_id**:
-    When both are available, construct a synthetic `SpanContext` with:
-    - `trace_id` = `txHash[0:16]` (deterministic)
-    - `span_id` = extracted from protobuf (sender's span_id → becomes parent)
-    - `trace_flags` = from protobuf
-    - `remote` = true (came from another node)
-
-    ```cpp
-    // Pseudo-code for the combined context:
-    auto detTraceId = trace::TraceId(txHash.data(), 16);
-    auto remoteSpanId = /* from extractFromProtobuf */;
-    auto remoteFlags = /* from extractFromProtobuf */;
-
-    trace::SpanContext combinedCtx(
-        detTraceId, remoteSpanId, remoteFlags, /* remote = */ true);
-    // Use as parent context for the new span.
-    ```
-
-- Edit `src/xrpld/app/misc/NetworkOPs.cpp` — update `processTransaction()`:
-  - `transaction->getID()` is already available at the top of the function.
-  - Create deterministic parent context from `txID`.
-  - Create `tx.process` span under this context.
-  - No protobuf context to extract here (NetworkOPs is intra-node), so
-    deterministic context alone is sufficient.
-
-- Add `trace_strategy` attribute to spans:
-  - Add `inline constexpr auto traceStrategy = "trace_strategy";`
-    to `TxSpanNames.h`.
-  - Set on each tx span: `span.setAttribute(tx_span::attr::traceStrategy, "deterministic")`.
-
-**Key new/modified files**:
-
-- `src/xrpld/overlay/detail/PeerImp.cpp` — restructured span creation
-- `src/xrpld/app/misc/NetworkOPs.cpp` — deterministic context for tx.process
-- `src/xrpld/telemetry/TxSpanNames.h` — new `traceStrategy` attribute constant
-- New or shared utility for `createDeterministicTxContext()` (location TBD: could be
-  a shared header like `include/xrpl/telemetry/DeterministicContext.h`, or file-local
-  if only used in two places)
-
-**Interaction with existing tasks**:
-
-- **Task 3.3 (PeerImp instrumentation)**: The span creation in `handleTransaction()`
-  must be restructured — the span currently starts before `txID` is known. This task
-  moves it after deserialization.
-- **Task 3.6 (Relay context propagation)**: Protobuf injection at the relay site
-  remains the same — `injectToProtobuf()` serializes the current span's `span_id`.
-  The receiver extracts it and combines with the deterministic `trace_id`.
-- **Phase 4a (Consensus deterministic trace ID)**: This task follows the same pattern.
-  Consider extracting a shared utility (e.g., `createDeterministicContext(uint256)`)
-  that both consensus and transaction tracing use.
-
-**Exit Criteria**:
-
-- [ ] `tx.receive` and `tx.process` spans have deterministic trace_id = `txHash[0:16]`
-- [ ] All nodes handling the same transaction produce spans under the same trace_id
-- [x] Protobuf `span_id` propagation still works when available (parent-child ordering)
-- [ ] Missing protobuf context (old peer) degrades gracefully to sibling spans, not lost traces
-- [ ] `trace_strategy` attribute set to `"deterministic"` on all tx spans
-- [ ] Trace queryable by tx hash (truncate hash → trace_id → direct lookup in Tempo)
-
-**Deliverables implemented (not in original plan)**:
-
-- **`SpanGuard::txSpan()` factory method** (`include/xrpl/telemetry/SpanGuard.h`):
-  Two overloads for creating transaction spans with deterministic trace IDs:
-  - `txSpan(category, group, name, txHash)` — standalone span (deterministic
-    trace_id from `txHash[0:16]`, no parent span_id).
-  - `txSpan(category, group, name, txHash, parentCtx)` — child span (deterministic
-    trace_id combined with protobuf-extracted parent span_id for relay ordering).
-
-- **`TxTracing.h` helper functions** (`src/xrpld/telemetry/TxTracing.h`):
-  File-local helpers that wrap `SpanGuard::txSpan()` for the two main PeerImp call
-  sites:
-  - `txReceiveSpan(txHash, parentCtx)` — creates `tx.receive` span with
-    deterministic trace_id and optional protobuf parent context.
-  - `txProcessSpan(txHash)` — creates `tx.process` span with deterministic
-    trace_id only (no protobuf parent, used intra-node).
-  - **Note**: `TxTracing.h` includes `xrpl.pb.h` unconditionally (outside
-    `#ifdef XRPL_ENABLE_TELEMETRY`) because `protocol::TMTransaction` appears in
-    the function signatures regardless of telemetry build mode.

-# Phase 4: Consensus Tracing Task List
-
-> **Goal**: Full observability into consensus rounds — track round lifecycle, phase transitions, proposal handling, and validation. This is the RUN phase that completes the distributed tracing story.
->
-> **Scope**: RCLConsensus instrumentation for round starts, phase transitions (open/establish/accept), proposal send/receive, validation handling, and correlation with transaction traces from Phase 3.
->
-> **Branch**: `pratik/otel-phase4-consensus-tracing` (from `pratik/otel-phase3-tx-tracing`)
-
-> **Note on attribute names**: the `xrpl.<domain>.<field>` keys shown below are
-> written in the older dotted form for readability — it mirrors how the fully
-> qualified attribute reads in a Tempo trace view. The implemented keys follow
-> the convention in [CONTRIBUTING.md](../CONTRIBUTING.md#telemetry-span-attribute-naming)
-> (underscore form, e.g. `consensus_round`, `consensus_mode`); the
-> `*SpanNames.h` constants are the single source of truth.

-## Task 4.1: Instrument Consensus Round Start ✅
-
-**Objective**: Create a root span for each consensus round that captures the round's key parameters.
-
-**Status**: DONE (implemented via Task 4a.2 `startRoundTracing()` helper).
-
-**What was done**:
-
-- `RCLConsensus::Adaptor::startRoundTracing()` creates `consensus.round` span
-  via `SpanGuard::hashSpan()` (deterministic) or `SpanGuard::span()` (attribute strategy)
-- Attributes set: `xrpl.consensus.ledger_id`, `xrpl.ledger.seq`,
-  `xrpl.consensus.mode`, `trace_strategy`, `xrpl.consensus.round_id`
-- Round span stored as `roundSpan_` member in `RCLConsensus::Adaptor`
-- `roundSpanContext_` snapshot captured for cross-thread span linking
-
-**Key modified files**:
-
-- `src/xrpld/app/consensus/RCLConsensus.cpp`
-- `src/xrpld/app/consensus/RCLConsensus.h` (span and context members)

-## Task 4.2: Instrument Phase Transitions ✅
-
-**Objective**: Create child spans for each consensus phase (open, establish, accept) to show timing breakdown.
-
-**Status**: DONE. All consensus phases are now instrumented:
-
-- `consensus.establish` — created in `Consensus.h::startEstablishTracing()`
-- `consensus.ledger_close` — created in `RCLConsensus.cpp::onClose()`
-- `consensus.accept` / `consensus.accept.apply` — created in `onAccept()` / `doAccept()`
-- `consensus.phase.open` — `openSpan_` member in `Consensus.h`, created in `startRoundInternal()`, ended in `closeLedger()`
-
-**Design notes**:
-
-- `phase` attribute — phases are distinguished by span names instead
-- `phase.enter` / `phase.exit` events — not added (span start/end serves this purpose)
-- `phase_duration_ms` attribute — not set (span duration captures this)
-
-**Key modified files**:
-
-- `src/xrpld/app/consensus/RCLConsensus.cpp`
-- `src/xrpld/consensus/Consensus.h` (template-level establish phase tracking)

-## Task 4.3: Instrument Proposal Handling ✅
-
-**Objective**: Trace proposal send and receive to show validator coordination.
-
-**Status**: DONE. Both send and receive paths are instrumented.
-
-**What was done**:
-
-- In `Adaptor::propose()`:
-  - Creates `consensus.proposal.send` span via `SpanGuard::span()`
-  - Sets `xrpl.consensus.round` attribute
-
-- In `PeerImp::onMessage(TMProposeSet)`:
-  - Creates `consensus.proposal.receive` span
-  - Sets `trusted` attribute (bool)
-
-**Done here** (cross-node propagation, send + receive):
-
-- Trace context injection for `TMProposeSet::trace_context` in `propose()`
-- Receive-side extraction in `PeerImp::onMessage(TMProposeSet)` via
-  `telemetry::proposalReceiveSpan()` (parents the receive span on the
-  sender's context when a valid `trace_context` is present)
-
-**Not implemented** (deferred to Phase 4b):
-
-- `consensus.proposal.relay` span in `share(RCLCxPeerPos)`

-## Task 4.4: Instrument Validation Handling ✅
-
-**Objective**: Trace validation send and receive to show ledger validation flow.
-
-**Status**: DONE. Both send and receive paths are instrumented.
-
-**What was done**:
-
-- In `Adaptor::validate()` (called from `doAccept()`):
-  - Creates `consensus.validation.send` span via `Adaptor::createValidationSpan()`
-  - Uses `SpanGuard::linkedSpan()` to create a follows-from link to the round span
-  - Thread-safe: uses `roundSpanContext_` snapshot (captured on consensus thread,
-    read on jtACCEPT thread)
-  - Sets `xrpl.ledger.seq` and `proposing` attributes
-
-- In `PeerImp::onMessage(TMValidation)`:
-  - Creates `consensus.validation.receive` span
-  - Sets `trusted` attribute (bool)
-  - Sets `xrpl.ledger.seq` attribute
-
-**Not implemented** (deferred to Phase 4b — cross-node propagation):
-
-- Validated ledger hash, signing time attributes on send span (see Task 4.8)
-
-**Key modified files**:
-
-- `src/xrpld/app/consensus/RCLConsensus.cpp`

-## Task 4.5: Add Consensus-Specific Attributes ✅
-
-**Objective**: Enrich consensus spans with detailed attributes for debugging and analysis.
-
-**Status**: DONE. All core attributes are set across various spans, including the previously missing `tx_count` and `disputes_count`.
-
-**Implemented attributes** (across various spans):
-
-- `xrpl.ledger.seq` — on `consensus.round`, `consensus.accept.apply`
-- `xrpl.consensus.round` — on `consensus.proposal.send`
-- `xrpl.consensus.mode` — on `consensus.round`, `consensus.ledger_close`
-- `proposers` — on `consensus.accept`, `consensus.establish`, `consensus.update_positions`
-- `converge_percent` — on `consensus.establish`, `consensus.update_positions`, `consensus.check`
-- `tx_count` — on `consensus.accept.apply` span (in `doAccept()`)
-- `disputes_count` — on `consensus.update_positions` span (in `updateOurPositions()`)
-- `close_reason` — on `consensus.phase.open`, from `whyCloseLedger()` (`anomaly`, `others_closed`, `idle`, `normal`)
-- `close_time_avalanche_state` — on `consensus.establish`, terminal regime (`init`, `mid`, `late`, `stuck`)
-
-**Design notes**:
-
-- `phase` — phases distinguished by span names instead
-- `phase_duration_ms` — span duration captures this

-## Task 4.6: Correlate Transaction and Consensus Traces ✅
-
-**Objective**: Link transaction traces from Phase 3 with consensus traces so you can follow a transaction from submission through consensus into the ledger.
-
-**Status**: DONE. Transaction-consensus correlation implemented via `tx.included` events in `doAccept()`.
-
-**What was done**:
-
-- In `doAccept()` (RCLConsensus.cpp):
-  - Records `tx.included` events on the `consensus.accept.apply` span for each transaction in the accepted set
-  - Each event includes `xrpl.tx.id` attribute with the transaction hash
-  - This links consensus traces to individual transactions
-
-**Key modified files**:
-
-- `src/xrpld/app/consensus/RCLConsensus.cpp`

-
-## Task 4.7: Build Verification and Testing ✅
-
-**Objective**: Verify all Phase 4 changes compile and don't affect consensus timing.
-
-**What to do**:
-
-1. Build with `telemetry=ON` — verify no compilation errors
-2. Build with `telemetry=OFF` — verify no regressions (critical for consensus code)
-3. Run existing consensus-related unit tests
-4. Verify that `SpanGuard` factory methods compile to no-ops when disabled
-5. Check that no consensus-critical code paths are affected by instrumentation overhead
-
-**Verification Checklist**:
-
-- [x] Build succeeds with telemetry ON
-- [x] Build succeeds with telemetry OFF
-- [x] Existing consensus tests pass
-- [x] `SpanGuard` no-op implementation prevents overhead when telemetry is OFF
-- [x] Phase timing instrumentation doesn't use blocking operations

-## Task 4.8: Consensus Validation Span Enrichment — NOT DONE
-
-> **Source**: [External Dashboard Parity](../docs/superpowers/specs/2026-03-30-external-dashboard-parity-design.md) — adds validation agreement context inspired by the community [xrpl-validator-dashboard](https://github.com/realgrapedrop/xrpl-validator-dashboard).
->
-> **Upstream**: Phase 4 tasks 4.1-4.4 (span creation must exist).
-> **Downstream**: Phase 7 (ValidationTracker reads these attributes), Phase 10 (validation checks).
-
-**Objective**: Add ledger hash, validation type, and quorum data to consensus validation spans on both send and receive paths. This enables trace-level validation agreement analysis — filter by ledger hash to see which validators agreed for a given ledger.
-
-**Status**: Not implemented. None of the enrichment attributes are set. The `consensus.validation.send` span only has `ledger.seq` and `proposing`. The `consensus.accept` span has `quorum` set to `result.proposers` (not the actual validator quorum from `app_.validators().quorum()`). No `PeerImp.cpp` changes were made.
-
-**What to do**:
-
-- Edit `src/xrpld/app/consensus/RCLConsensus.cpp`:
-  - On the `consensus.validation.send` span (in `validate()` / `doAccept()`):
-    - Add `xrpl.validation.ledger_hash` (string) — the ledger hash being validated
-    - Add `xrpl.validation.full` (bool) — whether this is a full validation (not partial)
-  - On the `consensus.accept` span (in `onAccept()`):
-    - Add `validation_quorum` (int64) — from `app_.validators().quorum()`
-    - Add `proposers_validated` (int64) — from `result.proposers`
-
-- Edit `src/xrpld/overlay/detail/PeerImp.cpp`:
-  - On the `peer.validation.receive` span:
-    - Add `xrpl.peer.validation.ledger_hash` (string) — from deserialized `STValidation` object
-    - Add `xrpl.peer.validation.full` (bool) — from `STValidation` flags
-
-**New span attributes**:
-
-| Span                        | Attribute                          | Type   | Source                            |
-| --------------------------- | ---------------------------------- | ------ | --------------------------------- |
-| `consensus.validation.send` | `xrpl.validation.ledger_hash`      | string | Ledger hash from validate() args  |
-| `consensus.validation.send` | `xrpl.validation.full`             | bool   | Full vs partial validation        |
-| `peer.validation.receive`   | `xrpl.peer.validation.ledger_hash` | string | From STValidation deserialization |
-| `peer.validation.receive`   | `xrpl.peer.validation.full`        | bool   | From STValidation flags           |
-| `consensus.accept`          | `validation_quorum`                | int64  | `app_.validators().quorum()`      |
-| `consensus.accept`          | `proposers_validated`              | int64  | `result.proposers`                |
-
-**Rationale**: The external dashboard's most valuable feature is validation agreement tracking. By recording the ledger hash on both outgoing and incoming validation spans, we create the raw data for agreement analysis at the trace level. Example Tempo query:
-
-```
-{name="consensus.validation.send"} | xrpl.validation.ledger_hash = "A1B2C3..."
-```
-
-Phase 7's `ValidationTracker` builds metric-level aggregation (1h/24h agreement %) on top of this data.

-## Task 4.9: Consensus Span Attribute Gap Fill
-
-**Status**: COMPLETE
-
-**Objective**: Add workflow-critical attributes to consensus spans that enable operators to understand consensus outcomes, identify bow-out proposals, and correlate validations to specific ledgers.

-#### Close Time Attributes (consensus.accept.apply)
-
-The `consensus.accept.apply` span captures ledger close time agreement details
-driven by `avCT_CONSENSUS_PCT` (75% validator agreement threshold):
-
-- **`close_time_ripple_epoch_s`** — Agreed-upon ledger close time (XRPL epoch seconds). When validators disagree (`consensusCloseTime == epoch`), this is synthetically set to `prevCloseTime + 1s`.
-- **`close_time_correct`** — `true` if validators reached agreement, `false` if they "agreed to disagree" (close time forced to prev+1s).
-- **`close_resolution_ms`** — Rounding granularity for close time (starts at 30s, decreases as ledger interval stabilizes).
-- **`consensus_state`** — `"finished"` (normal) or `"moved_on"` (consensus failed, adopted best available).
-- **`proposing`** — Whether this node was proposing.
-- **`round_time_ms`** — Total consensus round duration.
-- **`parent_close_time_ripple_epoch_s`** — Previous ledger's close time (XRPL epoch seconds). Enables computing close-time deltas across consecutive rounds without correlating separate spans.
-- **`close_time_self_ripple_epoch_s`** — This node's own proposed close time before consensus voting.
-- **`close_time_vote_bins`** — Number of distinct close-time vote bins from peer proposals. Higher values indicate less agreement among validators.
-- **`resolution_direction`** — Whether close-time resolution `"increased"` (coarser), `"decreased"` (finer), or stayed `"unchanged"` relative to the previous ledger.
-
-**Exit Criteria** (from [06-implementation-phases.md §6.11.4](./06-implementation-phases.md)):
-
-- [x] Complete consensus round traces
-- [x] Phase transitions visible (open, establish, close, accept)
-- [x] Proposals and validations traced — send and receive; relay deferred to Phase 4b
-- [x] Close time agreement tracked (per `avCT_CONSENSUS_PCT`)
-- [x] No impact on consensus timing
-- [x] Transaction-consensus correlation (Task 4.6) — `tx.included` events in doAccept
-- [ ] Validation span enrichment (Task 4.8) — not implemented

-# Phase 4a: Establish-Phase Gap Fill & Cross-Node Correlation
-
-> **Goal**: Fill tracing gaps in the consensus establish phase (disputes, convergence,
-> threshold escalation, mode changes) and establish cross-node correlation using a
-> deterministic shared trace ID derived from `previousLedger.id()`.
->
-> **Approach**: Direct instrumentation in `Consensus.h` and `RCLConsensus.cpp`.
-> All spans use `SpanGuard` factory methods (`span()`, `hashSpan()`, `linkedSpan()`)
-> with `TraceCategory::Consensus` gating. Long-lived spans (round, establish) are
-> stored as `std::optional<SpanGuard>` class members. Short-lived scoped spans
-> (update_positions, check) are local variables. No macros are used — all tracing
-> is via direct `SpanGuard` API calls. `SpanGuard` compiles to no-ops when
-> telemetry is disabled.
->
-> **Branch**: `pratik/otel-phase4-consensus-tracing`
-
-## Design: Switchable Correlation Strategy
-
-Two strategies for cross-node trace correlation, switchable via config:
-
-### Strategy A — Deterministic Trace ID (Default)
-
-Derive `trace_id = SHA256(previousLedger.id())[0:16]` so all nodes in the same
-consensus round share the same trace_id without P2P context propagation.
-
-- **Pros**: All nodes appear in the same trace in Tempo/Jaeger automatically.
-  No collector-side post-processing needed.
-- **Cons**: Overrides OTel's random trace_id generation; requires custom
-  `IdGenerator` or manual span context construction.
-
-### Strategy B — Attribute-Based Correlation
-
-Use normal random trace_id but attach `xrpl.consensus.ledger_id` as an attribute
-on every consensus span. Correlation happens at query time via Tempo/Grafana
-`by attribute` queries.
-
-- **Pros**: Standard OTel trace_id semantics; no SDK customization.
-- **Cons**: Cross-node correlation requires query-time joins, not automatic.
-
-### Config
-
-```ini
-[telemetry]
-# "deterministic" (default) or "attribute"
-consensus_trace_strategy=deterministic
-```
-
-The C++ API to query this at runtime is `Telemetry::getConsensusTraceStrategy()`,
-which returns a `std::string const&` (`"deterministic"` or `"attribute"`).
-
-### Implementation
-
-In `RCLConsensus::Adaptor::startRound()`:
-
-- If `deterministic`:
-  1. Compute `trace_id_bytes = SHA256(prevLedgerID)[0:16]`
-  2. Construct `opentelemetry::trace::TraceId(trace_id_bytes)`
-  3. Create a synthetic `SpanContext` with this trace_id and a random span_id:
-     ```cpp
-     auto traceId = opentelemetry::trace::TraceId(trace_id_bytes);
-     auto spanId  = opentelemetry::trace::SpanId(random_8_bytes);
-     auto syntheticCtx = opentelemetry::trace::SpanContext(
-         traceId, spanId, opentelemetry::trace::TraceFlags(1), false);
-     ```
-  4. Wrap in `opentelemetry::context::Context` via
-     `opentelemetry::trace::SetSpan(context, syntheticSpan)`
-  5. Call `startSpan("consensus.round", parentContext)` so the new span
-     inherits the deterministic trace_id.
-- If `attribute`: start a normal `consensus.round` span, set
-  `xrpl.consensus.ledger_id = previousLedger.id()` as attribute.
-
-Both strategies always set `xrpl.consensus.round_id` (round number) and
-`xrpl.consensus.ledger_id` (previous ledger hash) as attributes.

-## Design: Span Hierarchy
-
-```
-consensus.round  (root — created in RCLConsensus::startRound, closed at accept)
-│   link → previous round's SpanContext (follows-from)
-│
-├── consensus.establish  (phaseEstablish → acceptance, in Consensus.h)
-│   ├── consensus.update_positions  (each updateOurPositions call)
-│   │   └── consensus.dispute.resolve  (per-tx dispute resolution event)
-│   ├── consensus.check  (each haveConsensus call)
-│   └── consensus.mode_change  (short-lived span in adaptor on mode transition)
-│
-├── consensus.accept  (existing onAccept span — reparented under round)
-│
-└── consensus.validation.send  (existing — reparented, follows-from link to round)
-```
-
-### Span Links (follows-from relationships)
-
-| Link Source                               | Link Target                | Rationale                                                                      |
-| ----------------------------------------- | -------------------------- | ------------------------------------------------------------------------------ |
-| `consensus.round` (N+1)                   | `consensus.round` (N)      | Causal chain: round N+1 exists because round N accepted                        |
-| `consensus.validation.send`               | `consensus.round`          | Validation follows from the round that produced it; may outlive the round span |
-| _(Phase 4b)_ Received proposal processing | Sender's `consensus.round` | Cross-node causal link via P2P context propagation                             |

-
-## Task 4a.0: Prerequisites — Extend SpanGuard and Telemetry APIs ✅
-
-**Objective**: Add missing API surface needed by later tasks.
-
-**Status**: Done, but implemented differently than originally planned. The macro-based
-approach (`XRPL_TRACE_CONSENSUS`, `XRPL_TRACE_ADD_EVENT`, `XRPL_TRACE_SET_ATTR`) was
-**not used**. Instead, all consensus tracing uses `SpanGuard` factory methods and
-direct method calls, which is cleaner and avoids macro control-flow issues.
-
-**What was done**:
-
-1. **`SpanGuard::addEvent()` with attributes** — implemented as planned:
-
-   ```cpp
-   using EventAttribute = std::pair<std::string_view, std::string_view>;
-
-   void addEvent(std::string_view name,
-       std::initializer_list<EventAttribute> attrs);
-   ```
-
-   Callers pass plain `string_view` pairs; the implementation converts internally.
-
-   ```cpp
-   // Actual usage in Consensus.h::updateOurPositions():
-   span.addEvent(
-       "dispute.resolve",
-       {{consensus::span::attr::txId, to_string(txId)},
-        {consensus::span::attr::disputeOurVote, dispute.getOurVote() ? "yes" : "no"}});
-   ```
-
-2. **Span link support** — implemented via `SpanGuard::linkedSpan()` static factory
-   instead of a `Telemetry::startSpan()` overload:
-
-   ```cpp
-   static SpanGuard linkedSpan(
-       std::string_view name, SpanContext const& linkTarget);
-   ```
-
-3. **No macros added** — `TracingInstrumentation.h` was not created. The `XRPL_TRACE_CONSENSUS`,
-   `XRPL_TRACE_ADD_EVENT`, and `XRPL_TRACE_SET_ATTR` macros from the original plan were
-   not implemented. All consensus tracing uses direct `SpanGuard` API:
-   - `SpanGuard::span()` — create scoped spans
-   - `SpanGuard::hashSpan()` — create spans with deterministic trace IDs
-   - `SpanGuard::linkedSpan()` — create spans with follows-from links
-   - `span.setAttribute()` — set attributes directly
-   - `span.addEvent()` — add events directly
-
-**Key modified files**:
-
-- `include/xrpl/telemetry/SpanGuard.h` — `addEvent()` overload, `EventAttribute` type alias
-- `src/libxrpl/telemetry/SpanGuard.cpp` — `addEvent()` implementation
-
----
-
-## Task 4a.1: Adaptor `getTelemetry()` Method — NOT DONE (Not Needed)
-
-**Objective**: Give `Consensus.h` access to the telemetry subsystem without
-coupling the generic template to OTel headers.
-
-**Status**: Not implemented as specified. The `getTelemetry()` adaptor method was
-not needed because `SpanGuard::span()` is a static factory method that internally
-checks telemetry state via the global `Telemetry` singleton. `Consensus.h` creates
-spans by calling `SpanGuard::span(TraceCategory::Consensus, ...)` directly, without
-needing adaptor access. Only `RCLConsensus::Adaptor` uses `app_.getTelemetry()`
-directly (for `getConsensusTraceStrategy()` in `startRoundTracing()`).
-
-**Key insight**: The `XRPL_TRACE_*` macro approach would have required
-`adaptor_.getTelemetry()`. Since macros were not used, this task became unnecessary.
-
----
-
-## Task 4a.2: Switchable Round Span with Deterministic Trace ID ✅
-
-**Objective**: Create a `consensus.round` root span in `startRound()` that uses
-the switchable correlation strategy. Store span context as a member for child
-spans in `Consensus.h`.
-
-**Status**: Done. Implemented in `Adaptor::startRoundTracing()`.
-
-**What was done**:
-
-- `RCLConsensus::Adaptor::startRoundTracing()` helper:
-  - Reads `consensus_trace_strategy` via `app_.getTelemetry().getConsensusTraceStrategy()`
-  - **Deterministic**: uses `SpanGuard::hashSpan()` with `prevLgr.id()` data
-  - **Attribute**: uses `SpanGuard::span(TraceCategory::Consensus, seg::consensus, "round")`
-  - Sets attributes: `xrpl.consensus.ledger_id`, `xrpl.ledger.seq`, `xrpl.consensus.mode`, `trace_strategy`, `xrpl.consensus.round_id`
-  - Captures `roundSpanContext_` snapshot for cross-thread span linking
-  - Saves `prevRoundContext_` from previous round for follows-from links
-
-- **`SpanGuard::hashSpan()` factory**: encapsulates deterministic trace ID logic:
-
-  ```cpp
-  static SpanGuard hashSpan(
-      TraceCategory cat, std::string_view name,
-      std::uint8_t const* hashData, std::size_t hashSize);
-  ```
-
-  Derives `trace_id = hashData[0:16]` so all nodes in the same round share
-  the same trace_id. Compiles to no-op when telemetry is disabled.
-
-- `consensus_trace_strategy` config parsed in `TelemetryConfig.cpp`,
-  stored in `Telemetry::Setup`, accessible via `Telemetry::getConsensusTraceStrategy()`
-
-**Key modified files**:
-
-- `src/xrpld/app/consensus/RCLConsensus.cpp` — `startRoundTracing()` implementation
-- `src/xrpld/app/consensus/ConsensusSpanNames.h` — **(new)** compile-time span name and attribute key constants
-- `include/xrpl/telemetry/Telemetry.h` — `consensusTraceStrategy` in Setup, `getConsensusTraceStrategy()`
-- `src/libxrpl/telemetry/TelemetryConfig.cpp` — parse new config option
-
----
-
-## Task 4a.3: Span Members in `Consensus.h` ✅
-
-**Objective**: Add span storage to the `Consensus` class so that spans created
-in `startRound()` (adaptor) are accessible from `phaseEstablish()`,
-`updateOurPositions()`, and `haveConsensus()` (template methods).
-
-**Status**: Done with documented plan deviation.
-
-**What was done**:
-
-- `establishSpan_` added to `Consensus` private members (as planned):
-
-  ```cpp
-  std::optional<xrpl::telemetry::SpanGuard> establishSpan_;
-  ```
-
-- **Plan deviation**: `roundSpan_`, `prevRoundContext_`, and `roundSpanContext_`
-  are stored in `RCLConsensus::Adaptor` (not `Consensus.h`) because the adaptor
-  has access to telemetry config for the deterministic trace ID strategy.
-
-- **No `#ifdef XRPL_ENABLE_TELEMETRY` guards**: Members use `std::optional<SpanGuard>`
-  and `SpanContext` which have no-op implementations when telemetry is disabled,
-  so `#ifdef` guards are unnecessary. The members are always present in the class
-  layout but incur negligible overhead.
-
-- Includes added unconditionally to `Consensus.h`:
-  ```cpp
-  #include <xrpl/telemetry/SpanGuard.h>
-  #include <xrpld/app/consensus/ConsensusSpanNames.h>
-  ```
-  No `TracingInstrumentation.h` include (file doesn't exist; macros not used).
-
-**Key modified files**:
-
-- `src/xrpld/consensus/Consensus.h`
-- `src/xrpld/app/consensus/RCLConsensus.h` (round span and context members)
-
----
-
-## Task 4a.4: Instrument `phaseEstablish()` ✅
-
-**Objective**: Create `consensus.establish` span wrapping the establish phase,
-with attributes for convergence progress.
-
-**Status**: Done. Implemented via three private helpers in `Consensus.h`.
-
-**What was done**:
-
-- `startEstablishTracing()` — creates `consensus.establish` span via
-  `SpanGuard::span(TraceCategory::Consensus, seg::consensus, "establish")`.
-  Called once at start of establish phase. No `#ifdef` guards needed —
-  `SpanGuard::span()` returns a no-op guard when telemetry is disabled.
-
-- `updateEstablishTracing()` — sets attributes on each `phaseEstablish()` call:
-  - `converge_percent` — `convergePercent_`
-  - `establish_count` — `establishCounter_`
-  - `proposers` — `currPeerPositions_.size()`
-
-- `endEstablishTracing()` — calls `establishSpan_.reset()` on phase exit.
-
-**Key modified files**:
-
-- `src/xrpld/consensus/Consensus.h` — `phaseEstablish()` method + 3 helper methods
-
----
-
-## Task 4a.5: Instrument `updateOurPositions()` ✅
-
-**Objective**: Trace each position update cycle including dispute resolution
-details.
-
-**Status**: DONE. Span, dispute events with yays/nays, and disputes_count attribute are all implemented.
-
-**What was done**:
-
-- Creates `consensus.update_positions` scoped span via
-  `SpanGuard::span(TraceCategory::Consensus, seg::consensus, "update_positions")`:
-
-  ```cpp
-  auto span = SpanGuard::span(TraceCategory::Consensus, seg::consensus, "update_positions");
-  ```
-
-- Attributes set:
-  - `converge_percent` — current convergence
-  - `proposers` — `currPeerPositions_.size()`
-  - `have_close_time_consensus` — close time consensus state
-  - `close_time_threshold` — `avCT_CONSENSUS_PCT`
-  - `disputes_count` — number of active disputes
-
-- Dispute events recorded via direct `span.addEvent()` call with yays/nays:
-  ```cpp
-  span.addEvent(
-      "dispute.resolve",
-      {{consensus::span::attr::txId, to_string(txId)},
-       {consensus::span::attr::disputeOurVote, dispute.getOurVote() ? "yes" : "no"},
-       {consensus::span::attr::disputeYays, std::to_string(dispute.getYays())},
-       {consensus::span::attr::disputeNays, std::to_string(dispute.getNays())}});
-  ```
-
-**Not implemented**:
-
-- `proposers_agreed` / `proposers_total` attributes — not set
-
-**Key modified files**:
-
-- `src/xrpld/consensus/Consensus.h` — `updateOurPositions()` method
-- `src/xrpld/consensus/DisputedTx.h` — added `getYays()` / `getNays()` (currently unused)
-
----
-
-## Task 4a.6: Instrument `haveConsensus()` (Threshold & Convergence) ✅
-
-**Objective**: Trace consensus checking including threshold escalation.
-
-**Status**: DONE. The `consensus.check` span is created with all planned attributes
-including the avalanche threshold.
-
-**What was done**:
-
-- Creates `consensus.check` scoped span via
-  `SpanGuard::span(TraceCategory::Consensus, seg::consensus, "check")`:
-
-  ```cpp
-  auto span = SpanGuard::span(TraceCategory::Consensus, seg::consensus, "check");
-  ```
-
-- Attributes set:
-  - `agree_count` — peers that agree with our position
-  - `disagree_count` — peers that disagree
-  - `converge_percent` — convergence percentage
-  - `have_close_time_consensus` — close time consensus state
-  - `threshold_percent` — set to `avCT_CONSENSUS_PCT` (75%)
-  - `consensus_result` — "yes", "no", or "moved_on"
-  - `avalanche_threshold` — the escalated weight from `getNeededWeight()` on the `consensus.update_positions` span
-
-**Key modified files**:
-
-- `src/xrpld/consensus/Consensus.h` — `haveConsensus()` method
-
----
-
-## Task 4a.7: Instrument Mode Changes ✅
-
-**Objective**: Trace consensus mode transitions (proposing ↔ observing,
-wrongLedger, switchedLedger).
-
-**Status**: Done.
-
-**What was done**:
-
-- In `RCLConsensus::Adaptor::onModeChange()`, creates a scoped span via direct
-  `SpanGuard::span()` call:
-
-  ```cpp
-  auto span = telemetry::SpanGuard::span(
-      telemetry::TraceCategory::Consensus, telemetry::seg::consensus, "mode_change");
-  span.setAttribute(consensus::span::attr::modeOld, to_string(before).c_str());   // "mode_old"
-  span.setAttribute(consensus::span::attr::modeNew, to_string(after).c_str());   // "mode_new"
-  ```
-
-- `MonitoredMode::set()` in `Consensus.h` calls `adaptor_.onModeChange(before, after)`.
-
-**Key modified files**:
-
-- `src/xrpld/app/consensus/RCLConsensus.cpp` — `onModeChange()`
-
----
-
-## Task 4a.8: Reparent Existing Spans Under Round ✅
-
-**Objective**: Make existing consensus spans (`consensus.accept`,
-`consensus.accept.apply`, `consensus.validation.send`) children of the
-`consensus.round` root span instead of being standalone.
-
-**Status**: DONE. All three spans are now parented under the round span.
-
-**What was done**:
-
-- `consensus.validation.send` uses `SpanGuard::linkedSpan()` to create a
-  follows-from link to `roundSpanContext_`. This is thread-safe because
-  `roundSpanContext_` is a lightweight `SpanContext` snapshot captured on the
-  consensus thread and read on the jtACCEPT worker thread.
-
-- `consensus.accept` and `consensus.accept.apply` now use
-  `SpanGuard::childSpan(name, roundSpanContext_)` instead of `SpanGuard::span()`
-  to explicitly parent under the round span context. This solves the cross-thread
-  parenting problem:
-  - `doAccept()` runs on the jtACCEPT worker thread (not the consensus thread)
-  - `childSpan()` explicitly passes the parent context, bypassing OTel's
-    thread-local context propagation
-
-**Key modified files**:
-
-- `src/xrpld/app/consensus/RCLConsensus.cpp`
-
----
-
-## Task 4a.9: Build Verification and Testing ✅
-
-**Objective**: Verify all Phase 4a changes compile cleanly with telemetry ON
-and OFF, and don't affect consensus timing.
-
-**What to do**:
-
-1. Build with `telemetry=ON` — verify no compilation errors
-2. Build with `telemetry=OFF` — verify `SpanGuard` compiles to no-ops
-3. Run existing consensus unit tests
-4. Verify `SpanGuard` / `SpanContext` members have negligible overhead when disabled
-5. Run `pccl` pre-commit checks
-
-**Verification Checklist**:
-
-- [x] Build succeeds with telemetry ON
-- [x] Build succeeds with telemetry OFF
-- [x] Existing consensus tests pass
-- [x] `SpanGuard` no-op path verified (no `#ifdef` needed — disabled at runtime)
-- [x] No new virtual calls in hot consensus paths
-- [x] `pccl` passes

-### Implementation Notes
-
-- **No macros**: The planned `XRPL_TRACE_CONSENSUS`, `XRPL_TRACE_ADD_EVENT`, and
-  `XRPL_TRACE_SET_ATTR` macros were not implemented. All consensus tracing uses
-  `SpanGuard` factory methods (`span()`, `hashSpan()`, `linkedSpan()`) and direct
-  method calls (`setAttribute()`, `addEvent()`). This avoids macro control-flow
-  issues and is cleaner than the planned approach.
-- **Separation of concerns**: All non-trivial telemetry code extracted to private
-  helpers (`startRoundTracing`, `createValidationSpan`, `startEstablishTracing`,
-  `updateEstablishTracing`, `endEstablishTracing`). Business logic methods contain
-  single-line calls to these helpers.
-- **Thread safety**: `createValidationSpan()` runs on the jtACCEPT worker thread.
-  Instead of accessing `roundSpan_` across threads, a `roundSpanContext_` snapshot
-  (lightweight `SpanContext` value type) is captured on the consensus thread in
-  `startRoundTracing()` and read by `createValidationSpan()`. The job queue
-  provides the happens-before guarantee.
-- **No `#ifdef` guards**: Span members use `std::optional<SpanGuard>` and `SpanContext`
-  which have no-op implementations when telemetry is disabled. No `#ifdef XRPL_ENABLE_TELEMETRY`
-  guards needed around members or includes.
-- **No `getTelemetry()` adaptor method**: `SpanGuard::span()` is a static factory that
-  internally checks telemetry state, so `Consensus.h` doesn't need adaptor access
-  for span creation. Only `RCLConsensus::Adaptor` accesses `app_.getTelemetry()` directly.
-- **Config validation**: `consensus_trace_strategy` is validated to be either
-  `"deterministic"` or `"attribute"`, falling back to `"deterministic"` for
-  unrecognised values.
-- **Plan deviation**: `roundSpan_` is stored in `RCLConsensus::Adaptor` (not
-  `Consensus.h`) because the adaptor has access to telemetry config and can
-  implement the deterministic trace ID strategy. `establishSpan_` is correctly
-  in `Consensus.h` as planned.

-# Phase 4b: Cross-Node Propagation (Future — Documentation Only)
-
-> **Goal**: Wire `TraceContextPropagator` for P2P messages so that proposals
-> and validations carry trace context between nodes. This enables true
-> distributed tracing where a proposal sent by Node A creates a child span
-> on Node B.
->
-> **Status**: NOT IMPLEMENTED. The protobuf fields and propagator class exist
-> but are not wired. This section documents the design for future work.

-## Architecture

-## Wiring Points
-
-| Message         | Inject Location                    | Extract Location                    | Protobuf Field             |
-| --------------- | ---------------------------------- | ----------------------------------- | -------------------------- |
-| `TMProposeSet`  | `Adaptor::propose()`               | `PeerImp::onMessage(TMProposeSet)`  | field 1001: `TraceContext` |
-| `TMValidation`  | `Adaptor::validate()`              | `PeerImp::onMessage(TMValidation)`  | field 1001: `TraceContext` |
-| `TMTransaction` | `NetworkOPs::processTransaction()` | `PeerImp::onMessage(TMTransaction)` | field 1001: `TraceContext` |
-
-## Span Link Semantics
-
-Received messages use **span links** (follows-from), NOT parent-child:
-
-- The receiver's processing span links to the sender's context
-- This preserves each node's independent trace tree
-- Cross-node correlation visible via linked traces in Tempo/Jaeger
-
-## Interaction with Deterministic Trace ID (Strategy A)
-
-When using deterministic trace_id (Phase 4a default), cross-node spans already
-share the same trace_id. P2P propagation adds **span-level** linking:
-
-- Without propagation: spans from different nodes appear in the same trace
-  (same trace_id) but without parent-child or follows-from relationships.
-- With propagation: spans have explicit links showing which proposal/validation
-  from Node A caused processing on Node B.
-
-## Prerequisites
-
-- Phase 4a (this task list) — establish phase tracing must be in place
-- `TraceContextPropagator` free functions (already exist in
-  `include/xrpl/telemetry/TraceContextPropagator.h`)
-- Protobuf `TraceContext` message (already exists, field 1001)

 - 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.

+For more information on responsible disclosure, please read this [Wikipedia article](https://en.wikipedia.org/wiki/Responsible_disclosure).
+
+## 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.

-We have partnered with Bugcrowd to manage this program. It is a private program, and security researchers can participate based on invitation. If you need access to the program, please email bugs@ripple.com with your Bugcrowd handle or Bugcrowd registered email, and we will get you added to the program. Once you have been added, please submit vulnerability reports through Bugcrowd, not by email. The detailed bug bounty policy is available on the Bugcrowd website.
+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.

-  - A binary that should have been retargeted to the system loader: check that
-    cmake/PatchNixBinary.cmake ran for it.
-  - Link the macOS system library instead of the Nix one - see
-    libresolvSystemStub in nix/darwin.nix.
-  - No system library exists (libstdc++): link it statically.
-  - None of the above: pin the toolchain into the package ID, following

-# Works on Linux, macOS, and Windows (Git Bash / MSYS). For every expected tool
-# it runs a version probe, collecting anything that is missing or fails to run,
-# and prints a summary at the end (exiting non-zero if anything is missing).
-#
-# The tool set is platform-aware:
-#   - Linux:   the full Nix CI environment (see nix/packages.nix, nix/ci-env.nix),
-#              with GCC, Clang and the sanitizer/coverage tooling. This script is
-#              run during the Nix Docker image build (nix/docker/Dockerfile), so
-#              the Linux list is kept in sync with that environment.
-#   - macOS:   the same tooling, minus GCC/g++/gcov/mold
-#   - Windows: the core build tools only (CMake, Conan, Git, Python).
-#              MSVC is expected to be provided separately and is not checked here.
-#
-# Some tools (clang-format, clang-tidy, doxygen, gcovr, gh, git-cliff, gpg,
-# pre-commit, run-clang-tidy) are present in our Linux CI images and in local
-# development setups, but not in the macOS CI environment. They are checked
-# everywhere except when running in CI on macOS.
-#
-# Tools that Nix also exposes under a version-suffixed name (`clang-tidy-22`,
-# `g++-15`, ...) are probed under both names: a suffixed name can break while
-# the plain one still works (see mkVersionedToolLinks in nix/packages.nix).
-#
-# Environment variables:
-#   CI                      if set, skip the tools above when on macOS.
