Per PR #6438 review thread r3250432621: known-command errors
(rpcTOO_BUSY, rpcNO_PERMISSION, etc.) were collapsing into a
single rpc.command.unknown span name, hiding per-command error
rates in dashboards. Same anti-pattern existed for gRPC, where
every method was bucketed under grpc.request with the method
relegated to an attribute.
- RPCHandler.cpp: doCommand error path uses cmdName as the span
suffix; the rpc_span::val::unknownCommand fallback only applies
when the request truly omits both command and method fields.
- GRPCServer.cpp: gRPC span name is now grpc.<MethodName>
(e.g. grpc.GetLedger). Method also retained as an attribute.
- GrpcSpanNames.h: drop the unused op::request constant; update
the span-hierarchy comment.
- RpcSpanNames.h: update the gRPC span diagram to match.
Dashboards on downstream phases will benefit from per-command
breakdowns without needing TraceQL attribute filters.

Phase-1a plan documents advertised OTLP/gRPC on port 4317 as the default
exporter, four unparsed [telemetry] config keys, and "Phase 4a Complete"
status with exit-criteria checkboxes marked done. Every downstream branch
through Phase 5 ships only OTLP/HTTP on port 4318 via OtlpHttpExporterFactory,
never parses the advertised keys, and the Phase 4 work is not yet delivered.
Fixes:
- 02-design-decisions.md: flip §2.1.1 SDK dependency recommendations to
OTLP/HTTP (shipped) with OTLP/gRPC marked Future. Update §2.2 architecture
diagram and text from OTLP/gRPC:4317 to OTLP/HTTP:4318. Rewrite §2.2.1 as
"OTLP/HTTP (Shipped)" and §2.2.2 as "OTLP/gRPC (Future Work — Planned
Upgrade)" with a concrete checklist (Conan dep, config parsing, factory
branch, runbook/dashboard updates) for landing the gRPC transport later.
- 05-configuration-reference.md: drop the fabricated exporter/otlp_grpc key
and the :4317 default from the sample config block and the options-summary
table. Move trace_pathfind, trace_txq, trace_validator, trace_amendment
into a new "Planned (not yet implemented)" table citing the phase that will
add each one. Keep the example config minimal so copy-paste does not produce
a silently-ignored stanza.
- 06-implementation-phases.md: reset Phase 4 Exit Criteria checkboxes from
[x] to [ ] (Phase 4 is not shipped at Phase-1a time). Rename "Phase 4a
Complete" to "Phase 4a Plan" and describe the work as future. Replace the
broken forward link to Phase4_taskList.md (introduced in the Phase 2 PR)
with a sentence pointing readers to where that spec will land. Renumber
the final section 6.12 to 6.11 so it sits directly after 6.10; section 6.11
("Effort Summary") was intentionally removed in earlier edits.
SpanGuard::span() hardcoded SpanKind::kInternal for every span. Tempo's
service-graph and spanmetrics RED calculations rely on kServer /
kConsumer / kClient / kProducer to classify inbound vs outbound vs
internal operations. With kInternal everywhere, the service graph
collapses to a single self-loop and RED metrics attribute all latency
to internal work.
Add categoryToSpanKind() mapping:
- Rpc -> kServer (inbound synchronous request)
- Peer -> kConsumer (inbound async peer message)
- Transactions -> kInternal
- Consensus -> kInternal
- Ledger -> kInternal
Only the single-argument overload is affected; childSpan / linkedSpan
continue to default to kInternal because they represent in-process
continuations of an already-kinded parent.
RPC span attributes use bare names (command, rpc_status, rpc_role) per
the naming convention in SpanNames.h, not xrpl.rpc.* qualified names.
Node health attributes (amendment_blocked, server_state) are resource
attributes set at Tracer init, not span attributes.

NetworkOPs.h and SpanNames.h were only needed for per-span
nodeAmendmentBlocked/nodeServerState calls, which were removed

- Drop xrpl.pathfind.* prefix from per-span attrs (source_account,
dest_account, fast, search_level, num_complete_paths, num_paths,
num_requests).
- Keep xrpl.pathfind.ledger_index qualified (rule 5: distinct from
xrpl.ledger.seq).
- Remove per-span nodeAmendmentBlocked/nodeServerState calls from
RPCHandler — promoted to resource-level attrs.
- Mark node-health attrs in SpanNames.h as RESOURCE-ONLY with doc.
