Add value mappings (0 Disconnected, 1 Connected, 2 Syncing, 3 Tracking,
4 Full) and matching red->green thresholds to the Sync State panel, so the
line, tooltip, and legend render state names and colors instead of bare 0-4.
Keeps the minimal custom-key convention; only the Sync State panel changes.

Rework the 10 Sync Diagnostics panels' legends to match the format used by the
existing panels: wrap each query in label_join + label_replace to build the
xrpl_ident label ([service_instance_id, xrpl_branch, xrpl_work_item] with empty
values stripped) and set displayName to "${series} ${xrpl_ident}". Verified
against a live node: renders as "Series [aws-dev-xrpl-1]" with no empty-label
gaps, identical mechanism to the original 15 panels. Only the new panels change.

Add a 10-panel "Sync Diagnostics" row that shows ledger-sync slowdown and its
causes, laid out top-to-bottom as symptom -> latency -> root cause:
- Red flags: Sync State, Validated Ledger Age, Ledger Close Rate
- Latency: Job Queue Wait p95 by type, NuDB Read Latency, I/O Scheduler p95
- Root cause: NuDB Cache Hit Ratio, NuDB Read Pressure, Job Queue Depth,
Load Factor & Peers
All panels use native beast::insight metrics introduced on this branch
(nodestore_state, ledgermaster_*, jobq_*_q, ios_latency, load_factor_metrics,
peer_finder_*) plus the consensus.mode_change span metric. Queries filter by
the dashboard's $node and tier variables and were verified against a live
node. Nodestore ratio panels use sum-by(identity) matching to bridge the
metric= sub-label.
Format matches the dashboard convention: minimal custom keys, ${DS_PROMETHEUS}
datasource uid, and the standard What/How/Reading/Healthy/Watch/Source/Function
description structure. Pure-append; existing panels untouched.

Document the two new ledger-correlation attributes in the data-collection
reference: add them to the transaction and TxQ attribute tables (with per-span
coverage), update the attribute count, and correct the txq.enqueue parent note
(parents to tx.process on the submission path via explicit context; a root on
the open-ledger rebuild path, correlated via current_ledger_seq).

Add current_ledger_seq / current_ledger_hash to the tx.process, tx.receive,
and txq.enqueue span-reference rows, correct the txq.enqueue parent note
(parents to tx.process on the submission path via explicit context; a root on
the open-ledger rebuild path), and add a "Correlating a transaction to the
ledger it was worked on" recipe joining the txID-keyed tx/txq spans to the
ledger trace via current_ledger_seq.

Add shared current_ledger_seq / current_ledger_hash span attributes so a
transaction's work can be joined to the ledger trace that produced it, and
fix discrepancy D1 (txq.enqueue was a detached trace root).
- Define current_ledger_seq / current_ledger_hash once in SpanNames.h and
re-export via `using` from TxQ/TxApply/Tx span-name headers. These name the
ledger being worked on (open/tentative apply or in-flight consensus build),
distinct from ledger_seq (the built/validated ledger on ledger.build /
consensus.round). Named after the RPC field ledger_current_index.
- txq.enqueue: set current_ledger_seq/hash from the view, and parent the span
to the caller's tx.process span via an explicit captured SpanContext (new
trailing TxQ::apply param) instead of a detached root. The parent is
explicit, not ambient-inherited, and the ScopedSpanGuard scope is RAII-bound
to the synchronous apply, so it cannot leak onto a reused worker (D1 fix).
On the open-ledger rebuild path no tx.process context exists, so it stays a
root and the attribute provides the correlation.
- tx.preclaim / tx.transactor: set both attributes from their ledger view.
tx.preflight is stateless (no view) and is the documented exception.
- tx.process / tx.receive: set current_ledger_seq from the current open ledger
index at submit/receive time (no hash: not yet applied to a ledger).
- Contract test pins the two new attribute key strings.
Neither key is a spanmetrics dimension, so there is no metric-cardinality
impact. Dashboards/collector/docs land on the later phases per the chain split.

The colocated span-name headers (RpcSpanNames.h, ConsensusSpanNames.h,
PeerSpanNames.h, etc.) hold only compile-time constant strings and live
next to their subsystem rather than under a telemetry/ directory, so the
existing dir-prefix ignores miss them. Add a **/*SpanNames.h glob so they
do not count against patch coverage; like the rest of the telemetry
surface they are not exercised in the coverage build.

Replace the raw "trace_id="/" span_id=" prefix literals and the bare 32/16
hex-width magic numbers in the log trace-context injection with named
constexpr constants (kTraceIdPrefix, kSpanIdPrefix, kTraceIdHexLen,
kSpanIdHexLen), documenting that the widths are the W3C 16-byte trace_id /
8-byte span_id rendered as lowercase hex. No behavior change.

The isValidJson2 call site in RPCCall.cpp already forces instantiation
of std::all_of over json::ValueConstIterator, so a regression that
removed the iterator traits would fail the real build. A dedicated
static_assert test is redundant; remove it.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
json::ValueConstIterator and ValueIterator declared difference_type,
reference and pointer but not value_type or iterator_category. Under
C++23, std::iterator_traits then classifies them as output iterators,
so std::all_of over a Value's members (isValidJson2 in RPCCall.cpp)
fails to instantiate on GCC 13/14 with:
cannot convert 'output_iterator_tag' to 'std::input_iterator_tag'
GCC 15 masks this via LWG-3798/P2609, but the perf CI image ships
GCC 13, so the source needs the traits regardless. The iterators wrap
a std::map iterator (++/-- only), so the category is bidirectional.
Add value_type + iterator_category to both iterators, include <iterator>,
and add a regression test asserting the traits and that std::all_of /
std::count_if compile and run over Value members.

The existing ignore list only covered src/xrpld/telemetry/, but the same
rationale — telemetry code is conditionally compiled behind
XRPL_ENABLE_TELEMETRY, which the coverage build does not enable — applies to
src/libxrpl/telemetry/ (SpanGuard.cpp, Telemetry.cpp, etc.) and the
include/xrpl/telemetry/ headers. Their lines are never executed in coverage
builds, so they were dragging patch coverage down on the telemetry PRs.
Extend the ignore list to match.
