The microsecond ladder's first edge was 100us, which sat ABOVE the mass of
every instrument using it. Measured on devnet: 99.3% of job_queued_us
samples, 92.5% of job_running_us and 90.4% of getobject_lookup_us fell in
that first bucket. histogram_quantile then interpolated inside bucket 0 and
returned `quantile / fraction_in_bucket_0 x first_edge` -- p75/p95/p99 of
job_queued_us read 75.52/95.66/99.69us against a prediction of
75.53/95.67/99.70. Three-decimal agreement: those panels were reporting
arithmetic on the bucket edge, not latency.
The fix was already half-written. kSubMillisecondBoundaries had been parked
in MetricsRegistry.cpp as [[maybe_unused]] with a comment noting exactly this
problem for nodestore reads. Its edges are now folded into kMicrosecondBuckets
rather than deleted, so the parked intent is carried forward: 1..1000us
resolution where the mass is, upper edges unchanged so multi-second stalls
stay measurable.
Also moves the GetObject count and charge ladders into HistogramBuckets.h, so
all five ladders have one owner and one set of invariant tests (29 now).
Adds check_bucket_parity.py, wired into the existing OTel naming workflow.
The C++ millisecond ladder and the collector's spanmetrics ladder are
specified to agree over their shared range; they were identical when shipped,
then the collector side alone was extended and nothing noticed for eleven
phases. The check asserts containment rather than equality, because jobs
outlive spans -- jobq_updatepaths averages ~60s, which no span approaches, so
demanding equality would force a ceiling that censors it. Verified it rejects
a missing collector edge, a bogus in-range edge, and a return to the 5s
ceiling.
ledger-data-sync's "Job Queue Wait p95 By Type" moves off the beast
jobq_*_q_milliseconds pair onto job_queued_us filtered by job_type. Those
beast metrics are ms-quantised at the source (Event rounds up to a whole
millisecond), so 94-100% of their samples sat in the first bucket and no
ladder change could fix them. Note the label values are camelCase
(job_type="ledgerData"), not the lowercase metric-name fragments.
Both histogram-fed alert thresholds re-validated and left unchanged, with the
measured basis recorded so neither gets tuned against the old artefact: only
0.0022% of job_queued_us samples exceed the 1s threshold, and every edge
bracketing the 1000ms ios_latency threshold survived the ladder change.
Docs: the rpc_size "known issue -- tracked separately" notes in the runbook
and 09-data-collection-reference are now resolved notes, the stale 10-edge
span_duration bucket list is corrected to the collector's real 20, and the
runbook gains a "Reading A Histogram Percentile" section covering both
saturation traps and the expected discontinuity after a ladder change.
The reference docs had drifted from the code in ways that break the reader
rather than merely misinform: PromQL examples that return no data, a rollback
flag that is a no-op, a sampling knob that does not exist, and two span parents
that moved. Code is treated as the truth throughout; where the code is the
defective side, the doc now records it as a known issue instead of describing
the bug as intent.
Renames the docs missed: histogram names gain the exporter's unit suffix
(ios_latency_milliseconds_bucket and four siblings), ledger_history_mismatch
gains _total, the StatsD-era quantile label gives way to le buckets,
rpc.request becomes rpc.http_request, traces_spanmetrics_calls_total becomes
span_calls_total, and the nine dotted xrpl.* span attributes are recorded as
renamed rather than left as live keys.
Re-parenting: consensus.update_positions and consensus.check are children of
consensus.establish, not of consensus.round.
Units and labels: state_accounting_*_duration is microseconds, not seconds;
cache_metrics label values are case-sensitive; object_count carries demangled
C++ type names. Nodestore read and write latency stays microseconds -- the
nanosecond accumulator change did not move the exported unit.
Adds what shipped but was undocumented: the ledger.acquire span, seven
consensus.round events, twelve span attributes, node_writes_duration_us, the
7-day validation-agreement window, the TxQ admission and reduce-relay metric
families, metrics_endpoint, and the phase-10 validation workflow.
Corrects claims that never held: 10% head sampling (it is fixed at 100%),
configurable redaction (it is unconditional), -DXRPL_ENABLE_TELEMETRY=OFF
(the flag is -Dtelemetry=OFF, default ON), FindOpenTelemetry.cmake and the
xrpl_telemetry target (neither exists), Promtail and a StatsD exporter in the
pipeline (neither exists), and Loki stream selection on job= (only
service_name is a stream label).
Phase 9 is marked complete, its provisioned alerting is attributed to the
branch that shipped it, and Phase 11 stays at zero except the one prerequisite
its code closes. Counts are reconciled repo-wide: 41 emitted span families,
15 dashboards on disk with 14 asserted, 13 alert rules in 5 groups.
Hardens the gate that let this drift through: Rule E of the naming check now
covers the reference docs, its allow-dotted marker is key-scoped and warns on
stale or empty use, a missing checked file is reported instead of silently
skipped, the test suite runs in CI, and doc paths trigger the check.
C++ and CMake changes are comment-only: three MetricsRegistry instrument names,
eight OTelCollector claims of a metric-name prefix that formatName never adds,
and the telemetry option's inverted default.
Add check_otel_naming.py and wire it into on-pr.yml so every PR validates
that span-attribute names stay consistent across the code, collector, Tempo,
dashboards, and docs.
- The valid key set is derived dynamically from the *SpanNames.h constants and
the resource attributes the code registers in Telemetry.cpp — no hardcoded
allowlist to drift.
- Each rule is presence-gated: it runs only when the file it needs is in the
tree, so the check is correct whether telemetry changes land in one PR or
several (the collector/Tempo/dashboard/runbook layers arrive in later phases).
- Rule A flags dotted span-attribute keys; Rule F flags string-literal
attribute keys and span-name arguments (values may be runtime data).
- stdlib-only, mirroring the levelization check (bare `python`, no pip step).
- Telemetry.h / SpanGuard.h @code examples now use *SpanNames.h constants so
the strict literal check passes.
- CONTRIBUTING.md documents the check and how to run it locally.

The refs as previously used pointed to the source branch, not the target branch. However, determining the target branch is different depending on the GitHub event. The pull request logic was incorrect and needed to be fixed, and the logic inside the workflow could be simplified. Both modifications have been made in this commit.
This change uploads the `libxrpl` library as a Conan recipe to our remote when (i) merging into the `develop` branch, (ii) committing to a PR that targets a `release*` branch, and (iii) a versioned tag is applied. Clio is only notified in the second case. The user and channel are no longer used when uploading the recipe.
Specific changes are:
* A `generate-version` action is added, which extracts the build version from `BuildInfo.cpp` and appends the short 7-character commit hash to it for merges into the `develop` branch and for commits to a PR that targets a `release*` branch. When a tag is applied, however, the tag itself is used as the version. This functionality has been turned into a separate action as we will use the same versioning logic for creating .rpm and .deb packages, as well as Docker images.
* An `upload-recipe` action is added, which calls the `generate-version` action and further handles the uploading of the recipe to Conan.
* This action is called by both the `on-pr` and `on-trigger` workflows, and a new `on-tag` workflow.
The reason for this change is that we have downstream uses for the `libxrpl` library, but currently only upload the recipe to check for compatibility with Clio when making commits to a PR that targets the release branch.
This change removes the `master` branch as a trigger for the CI pipelines, and updates comments accordingly. It also fixes the pre-commit workflow, so it will run on all release branches.
Right now, each pipeline invocation builds the source code from scratch. Although compiled Conan dependencies are cached in a remote server, the source build objects are not. We are able to further speed up our builds by leveraging `ccache`. This change enables caching of build objects using `ccache` on Linux, macOS, and Windows.
This change substitutes the secp256k1 source code copy by the Conan recipe added in XRPLF/conan-center-index#24, which updates the version of the library to 0.7.0.
This change triggers the Clio pipeline on PRs that target any of the `release*` branches (in addition to the `master` branch), as opposed to only the `release` branch.
Per XLS-0095, we are taking steps to rename ripple(d) to xrpl(d).
C++ include guards are used to prevent the contents of a header file from being included multiple times in a single compilation unit. This change renames all `RIPPLE_` and `RIPPLED_` definitions, primarily include guards, to `XRPL_`. It also provides a script to allow developers to replicate the changes in their local branch or fork to avoid conflicts.
This PR sets the fail-fast strategy option to false (it defaults to true), unless it is run by a merge group.

Clio should only be notified when releases are about to be made, instead of for all PR, so this change only notifies Clio when a PR targets the release or master branch.
This change wraps all GitHub conditionals in `${{ .. }}`, both for consistency and to reduce unexpected failures, because it was previously noticed that not all conditionals work without those curly braces.
For the purposes of being able to merge a PR, Github Actions jobs count as passed if they ran and passed, or were skipped.
With this change, if any of the jobs that "passed" depends on fail or are cancelled, then "passed" will fail. If they all succeed or are skipped, then "passed" is skipped, which does not prevent a merge.
This saves spinning up a runner in the usual case where things work, and will simplify our branch protection rules, so that only "passed" will need to be checked.
