f649670ef7 fix(telemetry): address the PR review findings
Four defects from the automated review on PR #7875, each verified against the
current tree before fixing (one further comment, the row-63 dashboard overlap,
was already fixed by an earlier commit and needed nothing).

1. Rule J could not detect an instrument-kind mismatch. instrument_kinds() wrote
   `kinds[wire] = ...`, so a wire name created through two different factories
   kept only the kind visited last and whichever emit site the file walk reached
   last silently decided the verdict. It now collects a set per name and reports
   the conflict itself -- one name exporting two instruments is the defect, and
   no suffix can be correct for both. Added a regression test that builds a name
   as both a counter and an observable gauge and asserts the message names both.

2. A duplicate connection was reported as `tls_fail`. The TLS handshake had in
   fact succeeded; PeerFinder simply already held a slot for that address, which
   is ordinary churn on a healthy node. Conflating the two made a rising
   `tls_fail` unreadable -- it could mean unreachable peers or merely a busy
   PeerFinder, and those need opposite responses. Added a distinct `duplicate`
   outcome and carried the widened vocabulary through every place that
   enumerates it: the panel description, both filter descriptions, the runbook
   branch table, the runbook outcome list and the expected_spans note. The
   `dial_outcome` template variable is a label_values() query, so it picks the
   new value up on its own.

3. ConnectAttempt::onShutdown had no `operation_aborted` guard, unlike the five
   other handlers in the same file. A clean teardown was therefore counted as
   `upgrade_fail`, inflating that outcome on any node shutting down with dials in
   flight.

4. ValidatorSite used the raw configured URI as a Prometheus label.
   [validator_list_sites] accepts credentials in the URI and ParsedUrl keeps them
   in username/password, so a configured `https://user:pass@host` would have
   copied the secret into a metric label and on into the collector, Prometheus
   and every dashboard. The label is now rebuilt from scheme, host, port and
   path -- everything needed to tell one site apart, and nothing more.

Verified: naming checker exits 0 with Rule J still passing all 40 real
instrument names; its unit tests now number 139 and all pass; 15 dashboards
validate; both workload JSON files parse; clang-tidy over the full compile
database reports no finding on either changed .cpp; pre-commit passes.

Not verified: not compiled. Item 4 introduces string concatenation and item 2 a
new constexpr, so CI's build is the first real check on both.

22fd5e8601 feat(telemetry): make the sync board readable, and time real node writes (WP-B4)
The board and runbook had grown by append across eight work packages, so
they read in the order the work was done rather than the order a node
progresses. This is the coherence pass; it adds no new instrumentation.

- Dashboard: 52 panels regrouped from two rows into nine that follow the
  fresh-start sequence — bootstrap, peer supply, sync state, acquire and
  SHAMap fetch, job queue, quorum and publish, terminal blockers, then
  back-fill and spans collapsed since they answer conditional questions.
  Layout only: no title, query or description changed.
- Runbook: the flat step list becomes a decision tree branching on the
  observed symptom, with the amendment-block check first because it is
  terminal. Each branch names the panels, what healthy and unhealthy look
  like, and what to conclude. The existing steps are kept as the detail
  bodies.
- Reference table: every signal name re-checked against the code and every
  named panel against the board; four stale panel references fixed.
- Validation: every signal is now either asserted or covered by a note
  explaining why a five-node local cluster cannot produce it.

Also fixes the write-latency signal, which was inert on a real node: the
store duration was only recorded on the database-import path, while the two
production store implementations did not time themselves, so an ordinary
node reported a write count with no latency. Both now time the backend
write, which is the disk work this signal exists to expose. Without it the
"existing database syncs slower than a fresh one" diagnosis had no primary
signal.

41b818b55b feat(telemetry): join a ledger's spans into one trace, add round histogram (WP-B3)
A slow fresh-sync ledger produced spans scattered across threads with no
way to relate them. They now share a trace id derived from the ledger's own
hash, the one value every participating site already holds, so nothing new
is plumbed across threads. This is the pattern the transaction pipeline
already uses for its tx id.

Joined: ledger.validate, ledger.store, and a new
consensus.validation.accept recorded when a trusted validation arrives. In
Tempo, searching one ledger hash returns them together, so an operator can
tell whether the ledger was slow to arrive, slow to be accepted, or slow to
be stored. They are siblings rather than a chain because the accept gate is
entered from three different threads, so no fixed parent order exists.

consensus.validation.accept also records why an arriving validation did or
did not advance the gate, which makes "validations arrive but are all
rejected" visible for the first time.

consensus_round_duration_ms turns the existing round-time span attribute
into a histogram, so a fleet trend needs a metric query rather than raw
trace inspection. An explicit bucket view is required, not optional: the
SDK default tops out at ten seconds while consensus abandons a round at two
minutes, so slow rounds would all fall in one bucket and every quantile
would read exactly ten seconds. Cost is one record per round.

Record layer: the histogram is native and needs no collector change. The
two new bounded attributes are added as span-metric dimensions to both
collector configs. The ledger hash stays out of them, since a per-ledger
dimension mints a series per ledger; it is indexed in Tempo as the join key.

The ledger.acquire span is not joined yet, because that file was being
changed concurrently. It is registered as an optional member of the join
group so nothing fails, and switching it is a one-line follow-up.

c0f223ee11 fix(telemetry): always finalize the ledger.acquire span (WP-B1)
The span only recorded an outcome on the normal completion path. An
acquire that stalled and was later swept ended with no outcome at all, and
its duration stretched to the sweep interval rather than the real fetch
time. So the one case these signals exist to catch, a fetch that never
finishes, was the one case that could not be traced, and aggregate outcome
and timeout rates read low exactly when nodes are stuck.

- Adds an abandoned outcome value for the swept-while-fetching case.
- Routes every exit through one idempotent finalizer, so a span is
  finalized exactly once whether it completes, fails, short-circuits on
  local data, or is destroyed mid-fetch. The destructor path cannot throw.
- Adds the ledger hash to the span and backfills the sequence once known,
  since by-hash acquires start without one and could not otherwise be tied
  to a specific ledger.
- Record layer: outcome stays a span-metrics dimension in both collector
  configs, which drift apart if only one is edited. The ledger hash is
  indexed in Tempo for trace search instead, because a per-ledger value as
  a metric dimension would mint a new series every ledger.

01dae36fb1 test(telemetry): align workload harness with shared attr names
- peer.validation.receive now asserts the shared bare ledger_hash /
  full_validation keys (was the dotted xrpl.ledger.hash and validation_full);
  PARITY_SPAN_ATTRS checks both on the peer span too.
- Fix a span-name drift: the per-transaction accept span is txq.accept_tx
  (op::acceptTx = "accept_tx"), not txq.accept.tx — the old assertion never
  matched and was silently skipped as optional.
- Drop the "intentionally dotted" notes; there is no dotted span attribute.

899fc3c912 fix(telemetry): drop conditional fee attrs from txq.enqueue required set
The txq.enqueue span sets tx_hash, tx_type, and txq_status on every
code path (TxQ.cpp:746/748/751), but fee_level_paid and
required_fee_level are set only on the fee-evaluated path
(TxQ.cpp:895-898), which is reached after the rejected and
applied_direct early exits. They are therefore not guaranteed on every
txq.enqueue span, so requiring them caused the validation harness to
fail whenever a txq.enqueue span took an early-exit path.

Remove the two conditional attributes from required_attributes and
document why in the span note.

fd1c8c6060 fix(telemetry): resolve Phase 10 validation failures surfaced by first full CI run
The print-env CI fix let the Telemetry Stack Validation job build and run the
workload harness end-to-end for the first time. It reported 129/136 checks
passing; this commit fixes the 7 real failures plus a latent regression-gate bug.

Validation-suite fixes (verified against the CI run's actual emission + live node):
- expected_metrics.json: the beast::insight job-depth gauge is `xrpld_jobq_job_count`,
  not `xrpld_job_count` (the latter is a Phase 9 OTel counter). Reverted the prior
  rename. Removed the statsd_histograms block (`xrpld_rpc_time`/`xrpld_rpc_size`):
  these RPC timers do not emit under the WS workload (0 series in CI).
- expected_spans.json: `tx_status` is only set on suppressed/known-bad receives, so
  it is no longer a required attribute of every `tx.receive`. Marked `pathfind.compute`
  and `pathfind.discover` optional and the `pathfind.request -> pathfind.compute`
  hierarchy as skip — the self-to-self XRP probe returns before computing paths in a
  fresh cluster with no liquidity, so only `pathfind.request` fires.

Regression-gate bug (telemetry-validation.yml "Print regression summary"):
- `jq -e` exits non-zero when its filter result is boolean false — the normal case
  for a populated (non-placeholder) baseline — which was misreported as
  "Failed to parse baseline JSON" and failed the job. Dropped `-e` (kept `-r`) so a
  non-zero exit genuinely means malformed JSON.

The optional-span handling and regression comparison both worked correctly in the
CI run (txq.* / pathfind.update_all skipped-when-absent, 0 regressions detected).

cb9fce6890 fix(telemetry): align Phase 10 workload harness with current OTel recording surface + fix CI
The Phase 10 validation harness had drifted from the code's recording surface
and the telemetry-validation CI job was failing before it could build.

CI fix (telemetry-validation.yml):
- Replace nonexistent local action ./.github/actions/print-env with the remote
  XRPLF/actions/print-build-env (the build-xrpld job failed in 56s on this).
- Sync prepare-runner and upload-artifact action SHAs to the canonical workflow.

Recording-surface reconciliation (docker/telemetry/workload/):
- Migrate span attributes from dotted xrpl.<domain>.<field> to the bare/underscore
  form introduced by the 2026-05-13 span-attr naming redesign (tx_hash, peer_id,
  ledger_seq, consensus_mode, consensus_round, full_validation, quorum, ...).
  Dotted xrpl.ledger.hash is retained only on peer.validation.receive (shared
  constant), while consensus.validation.send uses bare ledger_hash.
- Fix attribute placement: tx.apply carries tx_count/tx_failed (not ledger_seq);
  ledger.build carries ledger_seq/close_* (not tx_count/tx_failed).
- Replace the phantom rpc.request span with the real WS root rpc.ws_message; drop
  the never-emitted duration_ms; rebuild the parent-child map accordingly.
- Add the new spans the code emits: apply-pipeline stage spans
  (tx.preflight/preclaim/transactor with stage/tx_type/ter_result), txq.*,
  consensus sub-spans (round/establish/update_positions/check/phase.open),
  ledger.acquire, grpc.*, pathfind.*. Conditional spans are marked optional so
  they are skipped (not failed) when the workload does not exercise them.
- validate_telemetry.py: service.name and Loki job label rippled -> xrpld; fix
  PARITY_SPAN_ATTRS (rename the 4 real attrs, drop the 3 that are metrics not span
  attrs); add optional-span handling that skips missing optional spans while still
  validating attributes when present.
- expected_metrics.json: rippled_ -> xrpld_ on all beast::insight/overlay metrics,
  xrpld_job_count, the 15 on-disk xrpld-* dashboard UIDs, and the real bare
  spanmetrics dimension labels.
- regression-metrics.json + baseline-timings.json: rpc.request -> rpc.ws_message.

Metrics pipeline fix:
- Switch node [insight] config from server=statsd/prefix=rippled to server=otel +
  /v1/metrics endpoint + prefix=xrpld across run-full-validation.sh,
  xrpld-validator.cfg.template, benchmark.sh and the workload compose. The
  collector has no StatsD receiver, so system metrics only reach Prometheus over
  OTLP.

Synthetic load for new spans:
- Add ripple_path_find to the RPC load generator (drives pathfind.* spans).
- Add a high-TPS txq-burst workload phase to force fee escalation (drives txq.*).

All facts verified against the *SpanNames.h headers and a live xrpld node +
collector (Tempo service.name=xrpld, tx.preflight attrs [stage,ter_result,tx_type],
279 xrpld_ Prometheus metrics and zero rippled_).
