The three close-time span attributes hold NetClock readings, which are whole
seconds since the XRP Ledger epoch of 2000-01-01 rather than the Unix epoch.
Neither the unit nor the epoch was recoverable from the key, so a consumer
rendering one as a wall-clock time without first adding the epoch offset lands
roughly thirty years early. The sibling close_resolution_ms already named its
unit, so the header disagreed with itself.
close_time -> close_time_ripple_epoch_s
parent_close_time -> parent_close_time_ripple_epoch_s
close_time_self -> close_time_self_ripple_epoch_s
Emitted values do not change; only the keys do. The public RPC response fields
of the same name are deliberately untouched, as renaming those would break the
ledger API.
Review of the preceding commits found a clang-tidy failure and a convention
break, both rooted in the same place: the enum-to-label helpers were put in
ConsensusSpanNames.h, which pulled two domain headers into it.
misc-include-cleaner rejected the new test: it used xrpl::LedgerCloseReason
without directly including ConsensusTypes.h, relying on the transitive
include. misc-* is enabled and this path is not in IgnoreHeaders, so it would
have failed CI.
ConsensusSpanNames.h had also become the only one of the eight *SpanNames.h
headers to include anything beyond SpanNames.h. That cost is paid by every
consumer: PeerImp.cpp, ConsensusReceiveTracing.h and RCLConsensus.cpp want
only name and key constants, but were newly compiling ConsensusTypes.h and
DisputedTx.h through it.
Move both helpers to a new ConsensusSpanLabels.h, which owns the domain
includes. ConsensusSpanNames.h is dependency-free again like its siblings, and
the labels reach their only production caller, Consensus.h, directly.
Also from the review:
- phaseOpen() had grown to 81 lines, over the 80-line limit. Extract
annotateOpenStart() and annotateOpenClose(), which also removes the repeated
span guards. phaseOpen is 72 lines; startRoundInternal drops 103 to 93,
still over the limit but it was 99 before this work began.
- Note at the CLOG why the log text keeps the shouldCloseLedger name: existing
consumers match on it.
- whyCloseLedger's doc claimed "both log identically", implying the wrapper
logs too. It delegates, so the logging happens once either way.
- Cross-reference proposers_validated and proposers_finished, which sit eight
lines apart and count different things: validators of the previous ledger
versus those already past it.
- The two static_asserts no longer sit inside TEST bodies with SUCCEED(); they
fire at compile time regardless. Also "consteval-safe" was wrong; they are
constexpr.
- SpanGuardFactory.cpp claimed a libxrpl test cannot include the consensus
span-name header. The new test in the same directory does exactly that, so
the claim is corrected to name the real constraint: the rpc_* constants it
needs live in an xrpld-level header.
SpanGuardFactory.cpp set dotted "xrpl.rpc.command"/"xrpl.rpc.status" attribute
keys. Test files are exempt from the naming check's Rule F (they pass arbitrary
literals to exercise the API), so this slipped through, but the keys should
still illustrate the underscore convention. Use "command"/"rpc_status".

The xrpl_tests target links only xrpl.libxrpl and cannot include the
xrpld-level ConsensusSpanNames.h / RpcSpanNames.h (CI build failure on
ubuntu-gcc-debug-arm64). Revert the test to underscore-form attribute
literals, restore the SpanNames.h include for seg::consensus, and drop
the now-unused tests.libxrpl -> xrpld.* levelization entries.

- tempo.yaml: align consensus filter tags with emitted keys
(consensus_mode, consensus_round, ledger_seq) instead of dotted form
- haveConsensus(): set span attributes before early-return paths so the
consensus.check span carries diagnostics even when consensus is not reached
- replace hardcoded consensus phase/result/vote literals with
ConsensusSpanNames.h val constants; add val::phaseOpen/Establish/Accepted
- ConsensusReceiveTracing.h: use canonical consensus::span constants instead
of duplicate inline detail:: names
- SpanGuardFactory test: use rpc_span / consensus::span constants now that
levelization permits the dependency

Instrument the consensus subsystem with OpenTelemetry spans covering
the full round lifecycle: round start, establish phase, proposal send,
ledger close, position updates, consensus check, accept, validation
send, and mode changes.
Key design choices adapted from the original Phase 4 implementation
to the new SpanGuard factory pattern introduced in Phase 3:
- Add SpanGuard::hashSpan() for category-gated hash-derived trace IDs
(consensus round spans share trace_id across validators via ledger hash)
- Add SpanGuard::addEvent() overload with key-value attribute pairs
(used for dispute.resolve events during position updates)
- Add ConsensusSpanNames.h with compile-time span name constants
following the colocated *SpanNames.h pattern from Phase 3
- Add consensusTraceStrategy config option ("deterministic"/"attribute")
for cross-node trace correlation strategy selection
- Use SpanGuard::linkedSpan() for follows-from relationships between
consecutive rounds and cross-thread validation spans
- Use SpanGuard::captureContext() for thread-safe context propagation
from consensus thread to jtACCEPT worker thread
Spans produced: consensus.round, consensus.proposal.send,
consensus.ledger_close, consensus.establish, consensus.update_positions,
consensus.check, consensus.accept, consensus.accept.apply,
consensus.validation.send, consensus.mode_change
