Clang-tidy misc-include-cleaner requires direct includes for all used
symbols. Application.cpp calls toBase58(TokenType::NodePublic, ...) at
line 1359 but did not directly include PublicKey.h.

Wire trace context into P2P message flow so distributed traces
link across nodes. TX relay injects SpanGuard context via
PropagationHelpers.h; consensus propose/validate injects via
TraceContextPropagator.h. Receive-side extraction in PeerImp
creates child spans for proposals and validations.
- Add TraceBytes struct and SpanGuard::getTraceBytes() for
extracting raw trace context without OTel type dependencies
- Add PropagationHelpers.h: injectSpanContext(SpanGuard, proto)
- Add ConsensusReceiveTracing.h: proposalReceiveSpan(),
validationReceiveSpan() with parent context extraction
- NetworkOPs::apply(): inject tx.process context before relay
- RCLConsensus::propose()/validate(): inject active span context
- PeerImp: create receive spans for proposals and validations
with sender's trace context as parent

- tx.receive span in PeerImp: convert to shared_ptr, capture in
checkTransaction lambda so it measures actual processing, not just
message parsing
- tx.process span in NetworkOPs: convert to shared_ptr, store in
TransactionStatus so it lives until the batch job processes the entry;
sync path unchanged (span destructs on function return)

Replace SpanGuard::txSpan(prefix, name, hash) with the generic
SpanGuard::hashSpan(TraceCategory, name, hash) that accepts a
TraceCategory parameter instead of hardcoding Transactions. This
enables reuse for consensus round spans (Phase 4) and any future
subsystem needing deterministic cross-node trace correlation via
hash-derived trace IDs.
Both overloads are replaced:
- hashSpan(cat, name, hash, size) — standalone with random span_id
- hashSpan(cat, name, hash, size, parentSpanId, parentSize, flags)
— with remote parent from protobuf context propagation
Add full span name constants (tx_span::receive, tx_span::process)
to TxSpanNames.h following the ConsensusSpanNames.h pattern.

Replace thread_local mt19937 with xrpl::default_prng() for span ID
generation — uses the project's existing thread-local xor-shift engine.
One call yields a uint64_t (8 bytes), filling the span ID in a single
memcpy without loops.
Fix compilation failure when XRPL_ENABLE_TELEMETRY is not defined:
move xrpl.pb.h include outside the #ifdef guard in TxTracing.h since
protocol::TMTransaction is used unconditionally in the function
signature.

Replace per-call std::random_device with thread_local std::mt19937 in
txSpan() for span ID generation. random_device is ~423x slower due to
/dev/urandom syscalls on each construction; mt19937 is seeded once per
thread and reused for all subsequent span IDs.
Update the SpanGuard class ASCII diagram to include txSpan factory
methods that were added in the hash-derived trace ID commit.

Derive trace_id from txHash[0:16] so all nodes handling the same
transaction produce spans under the same trace. Protobuf span_id
propagation provides parent-child relay ordering when available.
- Add SpanGuard::txSpan() factory methods (hash-derived trace ID)
- Add TxTracing.h helpers: txReceiveSpan(), txProcessSpan()
- Update PeerImp and NetworkOPs to use the new helpers

Move scattered string literals from PeerImp.cpp and NetworkOPs.cpp into
compile-time constants in src/xrpld/telemetry/TxSpanNames.h. Follows
the same StaticStr/join() pattern established in Phase 1c for RPC spans.
Constants cover: span prefixes (tx), operations (receive, process),
attribute keys (hash, local, path, suppressed, status, peerId,
peerVersion), and values (sync, async, knownBad).

- pathfind.update_all: wraps PathRequestManager::updateAll() on ledger
close with ledger_index attr

Delete TracingInstrumentation.h and replace all XRPL_TRACE_* macro
invocations with direct SpanGuard::rpcSpan() calls. SpanGuard's pimpl

TracingInstrumentation.h:
- Unify all span-creation macros to use std::optional<SpanGuard>
(fixes type mismatch between XRPL_TRACE_SPAN and SET_ATTR)
- Wrap XRPL_TRACE_SET_ATTR/EXCEPTION in do-while(0) (dangling-else)
- Move macros outside namespace blocks (macros are global)
- Cache telemetry reference to avoid double-evaluation
- Remove leaked _xrpl_span_ intermediate variable
- Add @note tags for thread safety, scope, and usage constraints
- Add 3 usage examples per CLAUDE.md requirements
ServerHandler.cpp:
- Remove misleading rpc.request span from onRequest() (span ended
before coroutine runs, producing orphan spans)
- Add rpc.http_request span to HTTP processSession() (runs inside
the coroutine, correct parent for rpc.process/rpc.command spans)
- Add XRPL_TRACE_EXCEPTION and error status in both catch blocks
(WS processSession and processRequest)
SpanGuard.h:
- Add null guards to all mutating methods (setOk, setStatus,
setAttribute, addEvent, recordException) for safety after discard()

Remove the single-arg span(name) factory that creates unconditional
spans without category gating. All call sites use the 3-arg
span(TraceCategory, prefix, name) variant which checks whether the
category is enabled in config before creating a span. The 1-arg form
was dead code with no callers.
