<cctype> added for std::tolower.
- Telemetry.cpp getMeter(): braces around single-statement if.

sync_instruments.h; add <xrpl/beast/utility/Journal.h> and <memory>;
make sdkProvider const.
- ValidationTracker.h: add <cstddef> for std::size_t.
- detail/ValidationTracker.cpp: use std::views::reverse range-based loop;

Drop the xrpld_ prefix from beast::insight metric names — the OTel
resource (service.name=xrpld) already identifies the service. formatName()
now lowercases and sanitizes spaces/dots to underscores for
Prometheus-compatible names.
Also fix 4 source strings containing spaces that produced invalid OTel
instrument names (silently rejected by the SDK).

- node-health.json: repoint the two "All Jobs" detail panels from the
__name__ regex over old xrpld_<job>_milliseconds_bucket names to the
native xrpld_job_running/queued_duration_us_bucket histograms, grouping
by the job_type label and legending on {{job_type}}.
- OTelCollector::callHooks: copy the hook list under mutex_ and invoke
handlers outside the lock. A handler can drop the last reference to an
OTelHookImpl, whose destructor calls removeHook() and re-acquires the
non-recursive mutex_ — invoking handlers under the lock could deadlock.
- ~OTelGaugeImpl: document that the SDK ObservableRegistry serializes
RemoveCallback against the Observe() callback pass with one mutex, so
callback removal is synchronous and gaugeCallback cannot run on a
dangling pointer after the destructor.

Give developers direct access to the full OpenTelemetry metrics API,
symmetric with getTracer(), so all seven OTel instrument types
(including UpDownCounter, sync Gauge, and the observable variants) are
reachable — not just the four beast::insight models.
- Telemetry: build and own the metrics pipeline (OTLP HTTP metric
exporter + PeriodicExportingMetricReader + SpanMetrics histogram view)
alongside the tracer, sharing the same resource attributes and TLS
config. Register it globally via metrics::Provider::SetMeterProvider
and expose Telemetry::getMeter(). Metrics enable with [telemetry];
the metrics endpoint is derived from the trace endpoint.
- beast OTelCollector: no longer owns a pipeline. It fetches the global
Meter, becoming a thin shim over the shared provider (legacy path
during beast deprecation). This also resolves the review note that the
metric exporter ignored [telemetry] use_tls — TLS now comes from the
shared telemetry pipeline.
- Add a libxrpl unit test covering getMeter() on the enabled (global
provider) and disabled (noop) paths, exercising an UpDownCounter.

- cmake: keep the opentelemetry-cpp umbrella target for the beast metrics
link and document why. The reviewer suggested linking individual
component targets to avoid over-linking, but the OTel Conan package
under-declares inter-component dependencies (the OTLP client references
sdk::common symbols without a declared edge), so naming components
directly reorders the static link into an unresolvable state. Verified
by building xrpl_tests both ways.
- OTelCollector.h: add usage examples, thread-safety and limitations
@note blocks to the class doc.
- OTelCollector.cpp: correct the @param name docs on the instrument
Impl constructors to describe the already-formatName()'d value.

The native OTel metrics path hard-coded service.name="xrpld" and stamped
no network attribute, while traces stamped a configurable service.name
and xrpl.network.type. Metrics therefore could not be filtered by service
or network. Align the two paths:
- OTelCollector::New / OTelCollectorImp gain serviceName + networkType
params. service.name uses the configured value (default "xrpld" when
unset, preserving today's behavior); xrpl.network.type is stamped when
provided. The key is a string literal because beast/insight sits below
the telemetry module and cannot include its SpanNames const.
- CollectorManager reads service_name from [insight], falling back to the
[telemetry] value, and receives the network type from the caller.
- Application derives the network type once via the shared
telemetry::networkTypeFromId, now declared in Telemetry.h and moved out
of an anonymous namespace so the trace and metric paths reuse a single
0/1/2 -> mainnet/testnet/devnet mapping (no duplication).
Dashboards (5 system-* files): add $service_name, $deployment_environment,
$xrpl_network_type template variables and wire them into every panel query
that filters by $node.

Two fixes so gauges register in Prometheus (via StatsD) even when their
initial/steady-state value is 0:
1. StatsDGaugeImpl m_dirty: default-init to true so the initial value
(0) is emitted on the first flush. Previously, gauges whose value
never changed from 0 were never flushed and never appeared
downstream.
2. io_latency_sampler firstSample_: new atomic<bool>, init true.
m_event.notify now fires when either firstSample_ is true (exchanged
to false) or lastSample >= 10 ms. This guarantees the io_latency
metric is registered on startup; subsequent sub-10 ms samples are
still suppressed to avoid flooding.
Clang-tidy fixes:
- Concatenate nested namespaces (modernize-concat-nested-namespaces)
in OTelCollector.h, OTelCollector.cpp, ValidationTracker.h/.cpp
- Add missing direct includes (misc-include-cleaner) in
ValidationTracker.cpp, test, CollectorManager.cpp, OTelCollector.cpp
- Make lock_guard variables const (misc-const-correctness)
- Add braces around single-line if/else (readability-braces-around-statements)
- Use designated initializer for WindowEvent (modernize-use-designated-initializers)
- Initialize LedgerEvent::seq field (cppcoreguidelines-pro-type-member-init)
Linker fix:
- Add ValidationTracker.cpp as source to xrpl.test.telemetry target
(it lives in src/xrpld/ but the test links against libxrpl only)
Levelization fix:
- Remove stale dependency edges from ordering.txt that were introduced
by the erroneous develop-merge commit

- Fix use-after-free: extract gauge callback to static function and call
RemoveCallback in ~OTelGaugeImpl() before unregistering from collector
- Use memory_order_acq_rel on callHooks() debounce CAS for proper
happens-before relationship between hook invocations
- Add explicit 2s timeout to ForceFlush() in destructor to prevent
blocking indefinitely when OTLP endpoint is unreachable at shutdown
- Add OTLP receiver to metrics pipeline so native OTel metrics from
xrpld are actually received by the collector
- Remove stale health check port from docker-compose (extension was
removed from collector config)
- Clarify fallback docs: StatsD path requires re-enabling receiver/port
- Fix comments: Counter uses uint64_t not int64_t, gauge clamps to
[0, INT64_MAX] not [0, UINT64_MAX]

Reverts 259 files that carried unrelated upstream changes through the
phase-6 merge: enum class removals (cppcoreguidelines-use-enum-class),
scoped_lock→lock_guard conversions (modernize-use-scoped-lock),
nodestore Backend API changes (void const* key), .clang-tidy config,
test infrastructure deletions, and miscellaneous develop changes.
These changes belong on develop, not in the telemetry PR chain.
