478b3e4b07 docs(telemetry): correct stale claims and citations in the harness docs
The workload README contradicted itself on --skip-loki: one bullet said CI always
passes it and so the two log-correlation checks are never exercised, another said
the workflow no longer passes it. The workflow mentions the flag nowhere, so the
first was the stale half.

Other claims checked against the tree and corrected:

- both the README and the plan doc described the push trigger as filtered on
  branch names. The workflow has no branches filter, deliberately, because
  GitHub ANDs branches with paths
- the plan doc printed 6 of the workflow's 12 paths globs, and claimed the
  workflow was 367 lines against an actual 451. The glob block is now generated
  from the workflow, and the line count dropped rather than restated
- rpcNOT_SUPPORTED does not exist anywhere in the tree. The symbol is
  RpcNotSupported, and the refusal sites are RipplePathFind.cpp:59-60 and
  PathFind.cpp:50-51, not :48-49 and :39
- RCLConsensus.cpp:666 and :663 are not log or event lines; the tx.included event
  is at :720 and the per-transaction debug log at :715
- LedgerMaster.cpp:463 is fixIndex, not the ledger.store span, which is at :470
- ServerHandler.cpp:705 is inside makeJsonError; processRequest is at :718
- file counts: docker/telemetry/workload/ is 25 files, include/xrpl/telemetry/ 13
- the optional-span bullet named five causes covering 10 of 16 entries, omitting
  the txq.* family and the WebSocket handshake
- the /api/v1/series choice was attributed to stale StatsD gauges; this harness
  runs no StatsD

A line number in run-full-validation.sh was cited in five places and drifts on
every edit to that file, so those now name the file only. The keygen helper's
header records what production does instead -- validator-keys-tool create_keys
then create_token, keeping the master key off the node -- and why a disposable
cluster does not.

3a63a17548 docs(telemetry): stop the harness contract narrating its own revisions
Notes across the workload contract described earlier versions of themselves, or
cited commits that only exist inside this chain. A squash merge publishes none of
it, so each reference resolves nowhere.

Notes that described their own earlier text:

- expected_spans.json: 'this note previously concluded', 'this note previously
  said', 'Un-skipped 2026-08-26', 'the reason had simply gone stale for two
  weeks' and 'the claim this entry carried' are replaced by the standing reason
  each entry holds. The wildcard pairs now say the validator globs the child via
  _span_name_matches(), and state the literal-collapse failure as what a
  different validator WOULD do rather than as history.
- regression-thresholds.json: 'an earlier version of this note wrongly claimed',
  'the earlier version oversold it' and 'an earlier note called that' become the
  cautions themselves -- do not reason from 'every ladder step is at least 2x',
  do not oversell the backstop, do not read a false fire as a missing override.
- test_check_regression_bounds.py: the docstring gives the reason a literal is
  wrong here, not the story of two tests that once hard-coded one.

Baseline-refresh history rewritten as measurement:

- README.md, baselines/README.md, telemetry-runbook.md and regression-metrics.json
  no longer attribute threshold moves to 'the 2026-08-26 refresh'. The evidence
  is kept as measurement -- span.tx.apply.p50 has read 0.7917 ms and 0.00597 ms
  on the same workload, 132x apart; job.acceptLedger.running.p95 has measured a
  5.74x floor on one baseline and 16.28x on another -- which is what supports the
  claim that a single-run baseline cannot bound these keys.

Two chain-only commit ids removed, d059f21bf3 and 3860c93db2. Neither is
reachable from develop, so both cease to exist on merge; the second is chain
bookkeeping. The facts they were cited for (the validator globs wildcards; the
span ladder's floor is 0.01 ms) are stated directly instead.

Capture provenance is deliberately kept: baseline-timings.json 'captured_at',
the 2026-08-26 baseline heading, and the 2026-08-24 figures cited as data.

Documentation, JSON note strings and one docstring only, no behaviour change.

8521b96d85 fix(telemetry): stop an incomplete capture becoming the committed baseline
The regression baseline is bootstrapped by copying a CI artifact. The workflow
tested only that timings.json existed, then printed it verbatim under a heading
inviting the reader to paste it in as the new baseline.

capture_timings.py writes that file and only then enforces --min-capture-ratio,
so an incomplete capture leaves a file that exists but covers fewer keys than
the contract declares. The verdict lived in CAPTURE_EXIT, a shell variable local
to run-full-validation.sh that no other program could read. So on a placeholder
baseline plus a thin capture, CI offered an incomplete artifact as the next
baseline, and pasting it narrowed the gate with nothing reporting that it had.
That is the failure shape this harness keeps producing: a degraded result that
looks exactly like a good one.

The artifact now carries its own completeness, next to metrics:

  "capture": { "declared": 20, "captured": 20, "min_ratio": 0.5, "complete": true }

complete is the same condition the producer exits 0 on, computed once with the
exit code read off it, so the flag and the status cannot drift apart. Any
consumer can now tell a complete capture from a thin one, not just CI.

Both paste-me paths refuse rather than warn: the workflow prints the counts and
an error annotation with no JSON, and the comparator explains on stderr while
leaving stdout empty, so a redirect cannot produce a plausible-looking file. A
warning above a copyable block is still a copyable block, and a reader who has
just hit a red gate is already predisposed to re-baseline. A missing capture
block fails closed.

Refusal is scoped to bootstrapping a baseline, not to comparing against one, so
artifacts captured before this change still replay: verified against the run the
current baseline came from, which carries no capture block and still reports 0
regressions. An injected regression is still caught, and the gated surface is
unchanged at 20 keys with 5 excluded.

a734da8b33 test(telemetry): recapture the baseline and stop gating what variance dominates
Refreshes baselines/baseline-timings.json from run 32964262700 at 8418d474a7,
byte-identical to the CI artifact. The previous baseline was captured at
6a82fc6f37, before the path-finding load was removed from the workload, so it
described a load shape the harness no longer runs.

Every absolute bound is re-derived, because the rule is hi_next minus baseline
and the baselines moved.

Three more keys stop being gated: span.tx.apply.p50, span.ledger.build.p50 and
span.consensus.ledger_close.p50. This is the rule the previous commit recorded
being applied, not a new exception -- a key is gateable only when its
run-to-run spread fits inside its bound.

The evidence is span.tx.apply.p50, which read 0.7917 ms in the old baseline and
0.00597 ms in this one. That is a 132x move between two runs of the SAME
workload. The old value happened to land mid-distribution, so hi_next minus
baseline gave a 4.21 ms bound that absorbed the spread; the new value lands in
the ladder's first bucket, so the same rule gives 0.0440 ms and cannot survive
one. Whether the gate functioned was decided by where in the distribution the
captured run happened to fall, which is not a threshold in need of tuning.
Measured spreads across four runs agree: 364x, 25.3x and 5.9x respectively.

All five excluded keys share one shape -- a baseline landing in the ladder's
low buckets, where the derived bound is tiny, together with large run-to-run
spread. Single-run baselines cannot support them; a multi-run baseline, or a
spread measurement captured alongside the baseline, is what would let them be
gated again. Not attempted here.

Both runs that would have reddened CI now replay clean, and an injected 10x
regression is still caught on 19 of the 20 remaining keys, 20 of 20 at 20x.
The exception is job.acceptLedger.running.p95, whose baseline fell while its
hi_next did not, moving its floor to 16.28x. It stays gated with that floor
recorded beside the other weak keys.

Also makes the bounds checker report a zero or negative baseline as a named
rule failure instead of dividing by it and raising.

3836078a78 fix(telemetry): stop gating ledger.validate p95 and p99, which vary too much
The regression gate has been red on runs with no code change. Only two of
the 25 gated keys ever tripped, both on the same span and never together:
run 32862589645 failed p99 at 25.8750 ms against a 1.0600 ms baseline
(+2341%), run 32867433073 failed p95 at 0.7500 ms against 0.2404 ms
(+212%), and in each run the other quantile sat well inside its own bound.
A real slowdown would move both. This is variance, not a defect.

Measured across four CI runs:

  span.ledger.validate.p50   0.0484 to 0.0778 ms    1.6x spread   kept
  span.ledger.validate.p95   0.1281 to 0.7500 ms    5.9x spread   excluded
  span.ledger.validate.p99   0.3875 to 25.8750 ms  66.8x spread   excluded

Both excluded quantiles reach past their trip point on a healthy run. The
mechanism is arrival timing, not slow code: the span opens only once a
quorum-completing validation arrives (LedgerMaster.cpp:987, inside
checkAccept, past the early return) and wraps the promotion work that
follows, so one slow consensus round dominates the tail of a 3m rate
window and which round that is differs every run.

Widening is not available and must not be attempted later: tolerating
25.8750 ms against a 1.0600 ms baseline needs a bound of about 24.8 ms,
which gates nothing. A bound admitting every healthy run's worst case
admits every regression too. p50 stays gated; it is stable.

THE GENERAL RULE, recorded so this does not recur: an absolute bound
derived as hi_next minus baseline comes from the histogram ladder, so it
budgets for quantization noise and for nothing else. It knows nothing about
how far a metric moves between runs on identical code. Before gating any
key, check its observed maximum across several runs against its trip point
and gate it only with margin. Spread alone proves nothing: tx.apply.p50
swings 364x and never fires, because its 5 ms trip point absorbs the range.
Of the 23 keys still gated the worst reaches 0.67 of its trip point.

Mechanism: spans.names lists span names while _quantiles is shared, so
dropping two quantiles of one span cannot be expressed by deleting a name.
regression-metrics.json gains an excluded_keys map from a flat key to the
reason it is not gated, subtracted by both prom_queries.py (so the key is
never queried) and check_regression_bounds.py rule A. A per-name quantile
override was rejected: a typo there leaves the key gating, whereas a typo
in an exclusion subtracts nothing and new rule F rejects it, along with an
empty reason, a leftover threshold override and a leftover baseline value.

Derived figures recomputed from the committed baseline: 25 gated keys to
23, detection floor 2.02x-9.43x to 2.02x-9.42x, weakly guarded keys ten to
nine, bound over baseline 102%-843% to 102%-842%. The baseline edit is a
deletion of two entries only, with no value rewritten.

Verified: both previously failing runs replay to zero regressions and exit
0; a tenfold increase injected into each of the 23 remaining keys in turn
is still caught in all 23 cases; rule F was confirmed load-bearing by
stubbing it out, which lets a stale exclusion pass.

e4926f55be fix(telemetry): derive workload gate bounds from the bucket above the baseline
The gate could not catch a regression on any sub-millisecond span.
compare_to_baseline.py requires both the percentage and the absolute bound to
breach, and every span shared one flat absolute bound of 10 ms (15 ms for p99)
calibrated for a 5-25 ms band the spans do not occupy. Against the baseline
captured on 2026-08-24, where 18 of the 28 quantiles gated at the time sat
below 1 ms, that bound sat 1.15x to 2000x above the metric it guarded, so the
AND never fired: a 100x regression injected into span.ledger.store.p95 reported
0 regressions and exit 0. Injecting a 10x regression into each key in turn was
caught on only 5 of 28.

Give every gated key its own absolute bound, equal to the distance from its
baseline to hi_next, the edge above the top of the bucket the baseline sits in.
The trip point is then exactly hi_next, so the gate fires only once the reading
clears the bucket above the baseline's own. That is the property a multiple of
the enclosing bucket width cannot provide: after the quantile crosses hi, the
interpolation happens across the next bucket, which on this ladder is up to
eight times wider, so no multiple of the enclosing width bounds the excursion.
Measured with a model-free reachability test, a single bucket crossing can
produce a false regression on 2 of 25 keys under the old flat bound and 0 of 25
under this rule. The smallest catchable regression is 2.02x to 9.43x per key.

The job queue bound had the same shape of problem on three of its four keys
(42x, 47x, 220x before). Defaults now sit at each ladder floor, leaving the
percentage bound operative for a metric that somehow reaches them.

Drop span.ledger.store from the gated surface. Its captured quantiles were
0.005, 0.0095 and 0.0099 ms, which is the ladder's 0.01 ms floor times the
quantile: every sample lands under 10 us, so the reported value does not move
even if each store slows from 2 us to 9 us. No bound can gate it. Presence is
still asserted by expected_spans.json and the integration test, and the rate is
still on the ledger-operations dashboard.

Add check_regression_bounds.py, wired into the same workflow step as the bucket
parity check. It fails when a bound is not the one its own baseline implies,
when a gated key has no override, when the baseline and metric surface disagree,
when the percentage bound would become operative, and when a baseline carries
the ladder floor signature. This gate has now broken three times through the
same drift between ladder, baseline and bounds, so documentation alone is not
enough.

compare_to_baseline.py is unchanged: its existing per-metric override mechanism
already expresses all of this.

A missing, unreadable or malformed input makes that check exit 1 naming the
input, rather than reporting success without having checked anything; only a
placeholder baseline, the documented bootstrap state, still exits 0. Its own
tests cover both halves of that contract plus one case per rule, and run in the
workflow before the check so a broken rule reads as a broken rule.

c4b8df9de1 test(telemetry): recapture span baselines on the current ladder
Copied verbatim from the timings.json produced by the telemetry-validation
run at 6a82fc6f37 (166/166 checks passed), which is the hand-off the
workflow prints for a placeholder baseline.

The numbers confirm why the previous baseline had to be voided. It was
captured 2026-06-05, before the collector's spanmetrics ladder gained
sub-millisecond edges, and its sub-1ms entries were arithmetic on the old
1ms first edge rather than latencies:

  span.ledger.store  p50/p95/p99  0.5 / 0.95 / 0.99   ->  0.005 / 0.0095 / 0.0099

Exactly 100x, because the old values were quantile x 1ms and the real ones
are quantile x 0.01ms. Since the gate only trips on increases, every
sub-millisecond span was unguarded against a 100x regression.

The job.* pair is back too, recaptured on the re-cut microsecond ladder
(floor 1us): job.acceptLedger.queued.p95 now reads 91.1us as a measurement,
where the voided value of 96.79us was 0.95/0.9926 x 100.

98ba282854 fix(telemetry): make the integration test correlate by construction, record the baseline log-level coupling
Three related follow-ups to running the workload at info.

integration-test.sh has its own log-trace correlation check that the workload
validator knows nothing about: check_log_correlation() greps each node's
debug.log for "trace_id=<hex> span_id=<hex>" and fails when it finds none, then
cross-checks a sample id against Tempo. At warning it had no guaranteed source.
The only warn-or-worse statement inside the activated accept scope is
RCLConsensus.cpp:671, which fires solely when a transaction throws, so the
check was passing incidentally -- helped by scanning whole files with no time
window. Raising it to info gives it the same guarantee the workload now has:
the consensus accept pair, one branch of which fires every accepted round.
Safe here because this script captures no latency baseline, so there is nothing
for the extra log I/O to contaminate.

baselines/README.md now records that the committed baseline is only valid at
the log level the harness generates. Logging is synchronous and several gated
spans contain log statements -- ledger.build has BuildLedger.cpp:81, and
consensus.accept has RCLConsensus.cpp:655/663/686 with :663 logging once per
transaction -- so the configured level is part of the measurement. Moving it
inflates or deflates the quantiles the gate reads without ever reporting a
regression, because the baseline moves with it. Changing the level therefore
requires re-capturing the baseline.

benchmark.sh keeps warning and keeps prefix=xrpld, and now says why. It
measures telemetry overhead as a delta between a telemetry-off and a
telemetry-on arm, so extra synchronous log I/O would inflate both arms and the
thresholds gate the result. The comment exists to stop a future reader
"aligning" it with the workload harness and quietly degrading the measurement.

1282645289 test(telemetry): invalidate job-queue baselines captured on the old ladder
The workload harness gates regressions on histogram_quantile over
job_queued_us / job_running_us, so re-cutting the microsecond ladder changes
what those queries return and the stored baselines no longer describe the
same measurement.

baseline-timings.json's job.acceptLedger.queued.p95 was 96.79us, which is
0.95 / 0.9926 x 100 -- the old 100us bucket edge scaled by the quantile, with
99.3% of samples beneath it. It was never a latency. Keeping it would make the
gate LESS sensitive rather than more: a genuine regression from a real 40us to
90us would still sit under 96.79us + 50% and pass.

Removes the four job.* entries and records why, including their values. The
comparer reports a metric absent from the baseline as "new metric (not in
baseline)" and skips it, so the span baselines stay live and gating continues
for everything unaffected. is_placeholder() still returns False, so this does
not disable the gate wholesale. Recapture the job.* numbers on a node running
the re-cut ladder.

Also corrects _bucket_note in regression-thresholds.json. It described the
spanmetrics ladder as 15 edges starting at 1ms; the collector config has 20,
including five sub-millisecond edges. The note's own reasoning was void too --
it justified the 10ms absolute span bound as "~2 low-end bucket widths", but
the low-end bucket width is 0.01ms, not 5ms. The bound is kept and justified
on the band where span quantiles actually sit, rather than on a derivation
from a ladder that no longer exists.

d059f21bf3 fix(telemetry): address review findings in the workload validation harness
Fixes the review findings on this PR that belong to files it owns, plus
several defects found while verifying those fixes. Findings in files owned
by upstream branches are routed there and left untouched here.

Correctness:
- tx_submitter: advance the account sequence only on results that actually
  consume one (tes*, tec*, terQUEUED). tem*/tef*/tel* never reach the
  ledger, so advancing left a permanent gap that every later submit from
  that account inherited. Add a re-fetch hatch so a repeated non-consuming
  failure cannot livelock on the same sequence, and gate the account check
  on funded-ness rather than list length.
- validate_telemetry: filter spans by name before collecting attributes, so
  a per-span attribute contract can no longer be satisfied by a sibling
  span; require exact name equality for non-wildcard children and glob
  matching for wildcards; bounds-check every returned series instead of
  only the first.
- collect_system_metrics: select xrpld by argv[0] rather than a substring
  match on the whole command line, which averaged in unrelated processes
  and reported their RSS as xrpld's. Count genuine 0.0 CPU readings, use a
  clamped nearest-rank p99 index, and record RPC latency only on success.
- benchmark: return each verdict through a named variable instead of a
  command substitution, so the pass/fail counters survive and the exit gate
  can fire. Scale before dividing in the percentage math, which truncated a
  1.26% impact to 1.00% and cleared a 1% threshold.
- compare_to_baseline: fall back to the absolute bound when the baseline is
  not positive, so a 0 -> 500 ms jump is no longer "within bounds".
- rpc_load_generator: bound each connection to one in-flight recv(), drain
  in-flight requests before closing, use a nearest-rank percentile, and
  report delivery shortfall so an under-delivered run cannot pass with a 0%
  error rate.

Fail loudly instead of silently:
- run-full-validation: treat a consensus timeout and a missing validated
  ledger as fatal infrastructure errors, and fold the orchestrator and
  benchmark exit codes into the final status. A degraded cluster previously
  ran a full validation pass and reported misleading downstream failures.
- collect_system_metrics: warn per empty measurement source, emit
  metrics_complete, and exit non-zero instead of substituting zeros that
  pass every threshold. Require GNU date with %N rather than falling back
  to a per-sample python3 fork that costs more than the threshold it is
  measured against.
- benchmark: distinguish "could not measure" from "exceeded thresholds",
  install a cleanup trap so a failure cannot leak nodes and ports, and
  report an unusable baseline as inconclusive.
- workload_orchestrator: bound subprocess communicate() and fail the exit
  gate on per-phase errors.

Also pins the workload compose images to the versions the sibling stack
already uses, hash-pins the Python dependencies, restricts the validator
config template to loopback, corrects the dashboard and metric counts in
the reference docs, drops a span from the regression gate that cannot fire
under a WebSocket-only workload, and narrows the teardown pkill pattern so
it no longer matches processes that merely mention the work directory.

Verified with a full harness run against a local five-node cluster:
158 of 158 checks passed with no regressions detected.

22e440aee1 fix(telemetry): correct the phase-10 validation harness against the code
The harness manifests asserted things the code cannot produce and missed most
of what it does. Two assertions were failing every run, and the metric set
covered 16 of the ~41 emitted names.

expected_spans.json: rpc.process was required with rpc.ws_message as its
parent, but it is created only in ServerHandler::processRequest() on the HTTP
path, so a WebSocket-only workload never produces it -- it is now optional and
parented to rpc.http_request, and the rpc.process -> rpc.command.* edge is
skipped with the real reason instead of a coroutine-context-loss diagnosis that
was never the cause. Adds the missing rpc.ws_upgrade span, corrects four
parents (consensus.mode_change, pathfind.request, and update_positions/check,
which are children of consensus.establish rather than consensus.round), and
demotes conditionally-set attributes out of required_attributes so a healthy
run stops failing. Counts recomputed from the file: 41 span types, 62 unique
required attributes.

expected_metrics.json: 16 -> 52 asserted entries across the job-queue, RPC
method, reduce-relay, overflow and validation families, plus the fifteenth
dashboard uid. Metrics the harness workload cannot exercise -- erroring RPC,
ledger-mismatch, TxQ overflow, and the lazily-created getobject_* instruments
-- are listed in a not_asserted group the validator skips, rather than as
assertions that would fail on a healthy node.

The workflow's push trigger listed two globs matching nothing
(include/xrpl/basics/Telemetry*.h, src/xrpld/app/misc/Telemetry*), so no C++
telemetry change ever triggered validation. Replaced with the paths the code
actually lives in, including src/libxrpl/beast/insight/** for the insight
export path the harness depends on. The four inert workflow_dispatch inputs are
now labelled UNUSED rather than looking like working knobs.

Docs: the workload README described a StatsD dirty-flag mechanism under a
member name that does not exist, on a code path the harness never uses -- it
sets [insight] server=otel, so gauges export through an observable-gauge
callback every cycle. Adds the missing txq-burst phase, reconciles three
different dashboard counts, and drops "posts summary to PR", which the workflow
has no permission to do. The runbook's phase-10 section loses the last
sampling_ratio reference (not a config key), gains a Regression Gate and CI
subsection covering the gate that can fail CI, and its compose-logs command now
names the workload compose file. cmake --preset default is left for a separate
change: no CMakePresets.json is tracked, so it is wrong everywhere it appears.

Also drops the dead exporter=otlp_http key the harness wrote into every node
config, and stops capture_timings.py defaulting --profile to a profile that
does not exist.

d83cb0bdb3 fix(telemetry): refresh regression baseline + widen bucket-noise thresholds
With validation now passing 133/133, the only remaining job failure was the
regression gate flagging 4 timing "regressions". Two compounding causes:

1. Stale baseline: the committed baseline was captured (2026-04-24) under the
   old, lighter workload — before the new txq-burst phase (60 TPS) existed. The
   heavier per-ledger work genuinely raises ledger.build / tx.apply /
   ledger.validate / acceptLedger timings, so every run regressed against it.
   Refreshed the baseline from the latest CI-measured timings (same workload).
2. Histogram quantization: SpanMetrics latency buckets are
   [1,5,10,25,...]ms, so a sub-millisecond quantile near a low-end boundary can
   jump a full bucket (1ms->5ms) between runs with no real change. The old
   absolute bounds (2-5ms) were narrower than one bucket width, so that jitter
   tripped the gate. Widened the default span bounds to 10-15ms (~2 low-end
   buckets) and pct to 50%, and the job_queue running bound to 20ms, to tolerate
   quantization noise while still catching genuine multi-bucket regressions. The
   consensus.* overrides (tight pct, large abs) are unchanged.

The refreshed baseline also picks up real rpc.ws_message timings (previously null
under the phantom rpc.request key).

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_).

dc13e9d680 fix: populate baseline from CI run, remove dead rpc_methods metrics
Populate baselines/baseline-timings.json from the green CI run
(24906110133, commit f11ebc1253). 25/31 metrics have non-null values;
6 span.rpc.* are null due to sparse data in the 3m window.

Remove the rpc_methods section from regression-metrics.json and its
thresholds. rippled_rpc_method_duration_us_bucket is never populated
because PerfLogImp::rpcEnd never calls MetricsRegistry::recordRpcFinished
— only recordRpcStarted is wired up (Phase 9 instrumentation gap).
The span-based rpc.request/rpc.process metrics via spanmetrics already
cover RPC latency.

577d1f8a21 fix: address review findings in regression gate
- capture_timings.py: fail when captured/total ratio < 50%
  (--min-capture-ratio). Prevents silent pass on unreachable Prometheus.
- run-full-validation.sh: set REGRESSION_EXIT=2 on capture failure so
  the final exit code reflects it. Update exit code docs in header.
- compare_to_baseline.py: extract _skip_delta helper to bring
  compute_delta under 80 lines. Fix 0.0-as-falsy bug in abs_bound
  resolution (use explicit None check instead of `or`). Remove dead
  variable override_prefix_key.
- prom_queries.py: extract _build_simple_entries and _build_job_entries
  to bring build_query_plan under 80 lines. Fix module docstring return
  type example. Use aiohttp.ClientTimeout instead of bare int.
- telemetry-validation.yml: add set -euo pipefail to regression summary
  step; guard jq calls with -e flag and fallback; fail on missing
  baseline file; emit ::warning annotation when timings.json missing.
- baselines/README.md: document the placeholder field.

df79d5e74b feat: add OTel-driven regression gate for Phase 10 telemetry validation
Captures per-span / per-RPC / per-job timings from Prometheus after the
workload run and diffs them against a committed baseline. Regression
requires breaching both a percentage and an absolute bound, tolerating
small-value noise. When the baseline is a placeholder, the comparator
emits the captured JSON in the exact schema for one-time paste into
baselines/baseline-timings.json, and the CI Step Summary surfaces that
block for the reviewer.

Scope: gate only — automated baseline persistence, benchmark.sh
PromQL migration, and the historical trend dashboard remain follow-ups.
