A freshly started node most often stalls before it ever peers or reaches
quorum, and that whole chain had no telemetry. Adds the six signals that
make it observable:
- dns_resolve_total / dns_resolve_latency_ms: configured-peer hostname
resolution, emitted from OverlayImpl so libxrpl stays independent.
- overlay_connect_total / overlay_dial_latency_ms: outbound dial outcome
by terminal reason, plus dial duration.
- handshake_negotiation_fail_total: protocol and network-id negotiation
rejections, labelled by reason, so a misconfigured network is no longer
indistinguishable from unreachable peers.
- unl_fetch_total and the unl_quorum gauge: validator-list fetch outcome
per site and trusted key count against the required quorum. Without
these a bad validators.txt leaves the node syncing forever with no
signal.
- clock_close_offset_seconds: network close-time offset, which server_info
hides below 60s but which stalls consensus participation.
Panels land in the Bootstrap row of the Ledger Sync Health dashboard, the
metrics are asserted by the workload validator, and both the reference and
the runbook flow describe them.
Levelization baseline regenerated: overlay now includes MetricMacros.h, so
the overlay/telemetry pair is reported one-way instead of bidirectional.

Brings coroutine-aware context storage + tx/consensus worker-body activation.
Resolved: Telemetry.cpp keeps both meterProvider_ (phase-7) and contextStorage_
(coro-aware); doc-09 keeps phase-7 structure and applies the pathfind.request →
rpc.command.<name> correction to phase-7's own PathFind section.

Brings coroutine-aware context storage, scoped rpc.command, coro-store-swap
tests, and the scoped pathfind.request forward.

Brings coroutine-aware OTel context storage forward: CoroAwareContextStorage,
its install in Telemetry, ScopedSpanGuard same-store assertion, and the
non-owning ScopedActivation helper.

Backs the OTel active-context stack with xrpl::LocalValue so the ambient
context follows a JobQueue::Coro across yield/resume. Not yet installed.

xrpl_branch and xrpl_node_role are stamped by the perf-iac harness --
infrastructure outside this repo's OTel code -- so they have no L1
(*SpanNames.h), L2 (collector config), or L6 (MetricsRegistry.cpp) source
Rule D can derive them from. Unlike the generic builtins set (Prometheus/
Grafana mechanics every OTel setup has), these are repo-specific and
narrow, so they get their own EXTERNAL_INFRA_LABELS constant: a visible,
documented, deliberately narrow exception to the 'no hardcoded allowlist'
design principle, not a silent workaround. Add test coverage.

xrpl_branch and xrpl_node_role are collector/infra-injected resource
labels used by perf-iac dashboards to identify the build under test and
its role in the perf cluster. They have no L1 span-attribute source or
L6 native-metric-label source (like the existing job/instance/job_type
builtins), so Rule D flagged them across every perf-iac dashboard.
Register them in the builtins set, matching the existing pattern for
infra-level dashboard labels. Add test coverage.

Convert leading /// blocks to house-style /** */ across the telemetry
files carried on this branch (using the updated fix_doxy.py). Also
regenerate levelization results. Comment-only: code is byte-identical.

Bring the 5 telemetry files introduced on this branch to the enforced
house Doxygen style (/** alone, ' * ' continuation prefix, no single-line
blocks) so the check-doxygen-style hook passes under CI's --all-files run.
Comment-only: code is byte-identical after comment stripping (verified).
Also regenerate levelization results: the committed ordering.txt carried
stale 'xrpl.telemetry > xrpld.consensus/rpc' edges that the current include
graph no longer produces.

rootSpan has the same (cat, prefix, name) signature as span(), so its
prefix/name arguments must be *SpanNames.h constants under Rule F/H. Add
rootSpan to the CALLSITE regex and CONSTANT_ARG_POSITIONS ({1,2}), update
the enumerating docstrings/README, and add two regression tests.

- Add job_type to otel-naming builtins (standard Prometheus label for
job-queue metrics used in node-health dashboard)
- Add OpenTelemetry SDK to UBSAN suppressions (intentional unsigned
integer overflow in attributemap_hash.h hash computation)
