The tx.receive span is created after the duplicate check, so it carries no
suppressed attribute and a dropped copy produces no span at all. How many were
dropped is the transactions_duplicate traffic category.
The plan doc offered `"attribute"` as the alternative to `"deterministic"`
for consensus_trace_strategy. The parser accepts `"random"`; "attribute"
described the correlation mechanism rather than the setting's value. Note
also that the alternative is experimental and not used.
One conflict, in SpanGuard.h: this branch added struct TraceBytes and upstream
added enum SpanRole at the same position after TraceCategory. Unrelated
declarations, so both are kept.
Review feedback on the plan documents. Four kinds of error:
- Symbols that do not exist: ConsensusProposal::prevLedger_ (it is
previousLedger_), RCLConsensusAdaptor (it is RCLConsensus::Adaptor, and
startRound() is on RCLConsensus itself), and RPCHandler::doCommand (a free
function, xrpl::rpc::doCommand).
- Attribute keys: the tables used ledger_index, which no telemetry code emits.
Same concept as ledger_seq but a different referent, so the code disambiguates
by prefix: current_ledger_seq for the open ledger a transaction targeted,
ledger_seq for a closed or validated one. A note now states which is which.
- TraceQL that does not parse: span-field predicates need braces, status.code
is not an intrinsic (status = error), and avg(duration) does not take a by
clause (avg_over_time does). All five re-tested against Tempo.
- The StatsD comparison omitted the Histogram instrument, which aggregates at
the point of measure, and the when-to-use table had no row for a metric that
spans cannot afford to carry.
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.
Add trace_id = txHash[0:16] strategy so all nodes handling the same
transaction independently produce spans under the same trace_id,
combined with protobuf span_id propagation for parent-child ordering.

Strip effort/risk columns from task tables and remove the §6.9 Effort
Summary section with its pie chart and resource requirements table.
Renumber §6.10 Quick Wins → §6.9.
