The consensus headers moved into the isolated xrpl/consensus module and
took a dependency on xrpl/telemetry for the tracing span constants, but
two things were left behind:
- Four includes still pointed at the old src/xrpld/consensus/ location,
which no longer exists, so the build failed with
"fatal error: 'xrpld/consensus/ConsensusParms.h' file not found".
- xrpl.libxrpl.consensus never linked xrpl.libxrpl.telemetry. add_module
isolates each module's headers, so xrpl/telemetry/SpanNames.h was not
on the include path even once the include was repointed.
Repoint the stale includes at xrpl/consensus/, and declare the telemetry
module before consensus so consensus can link it. Regenerate ordering.txt
for the resulting edge.
The phase-2 merge re-added the pre-telemetry `add_module(xrpl tx)` block
without removing it, leaving the module declared twice. CMake's
add_library rejects a repeated target name, so configure failed before
any compilation:
add_library cannot create target "xrpl.libxrpl.tx" because another
target with the same name already exists.
Drop the stale pre-telemetry block and keep the one that follows
add_module(xrpl telemetry), which links both ledger and telemetry.
libxrpl/tx needs the telemetry link for the tx.transactor span, and
levelization already records `libxrpl.tx > xrpl.telemetry`.

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.

Forward-merge the OTel naming-check Rule C/D fixes and the phase 2-9 chain.
Conflict resolutions:
- 02-design-decisions.md TxQ Attributes: take the convention-correct markdown
table (txq_* keys) over the stale planned-attrs code block.
- SpanGuardFactory.cpp: keep the explanatory comment for the literal attribute
keys in the libxrpl test.
Bring the hardened OTel naming check (Rule E fix + 71 tests) and the phase 1-6
convention work forward into phase 7 (native metrics).
Conflict resolution:
- 05-configuration-reference.md: kept phase-7's native-OTLP metrics story
(server=otel, /v1/metrics) over phase-6's superseded StatsD scrape job, in
prose form (no code block).
- ordering.txt/loops.txt: regenerated via generate.py (not hand-edited).
