8172c0c811 Merge branch 'pratik/otel-phase9-metric-gap-fill' into pratik/otel-phase10-workload-validation
Forward-merge the OTel naming-check Rule C/D fixes and the phase 2-9 chain.

Conflict resolutions:
- 02-design-decisions.md TxQ Attributes: take the convention-correct markdown
  table (txq_* keys) over the stale planned-attrs code block.
- SpanGuardFactory.cpp: keep the explanatory comment for the literal attribute
  keys in the libxrpl test.

25227141b3 Merge branch 'pratik/otel-phase8-log-correlation' into pratik/otel-phase9-metric-gap-fill
Bring phase-8 (log correlation) and the naming-check + BasicConfig fixes forward
into phase 9 (native-metrics gap fill). Phase 9 adds MetricsRegistry and
LedgerSpanNames.h.

Conflict resolution:
- presentation.md: took phase-9's restructured deck — sampling now lives in
  Slide 8 (Head vs Tail) and the Phase 10/11/12 future-phase slides; phase-8's
  older standalone sampling section is superseded (no content lost).
- ordering.txt/loops.txt: regenerated via generate.py.

Naming check: A/B/E/F/G green. Rule D reports 6 findings that are all check
gaps, not data errors (verified every dashboard label traces to code):
  - 3 are TraceQL `span.<attr>` references (bare attr is in L1); Rule D should
    strip the span./resource. scope prefix.
  - 2 (`reason`, `job_type`) are native OTel metric labels emitted by
    MetricsRegistry.cpp — a new source of truth the check does not yet model.
The Rule D enhancement lands on phase-1c and merges forward.

3236daf08e Merge branch 'pratik/otel-phase7-native-metrics' into pratik/otel-phase8-log-correlation
Bring native-metrics (phase 7) and the naming-check work forward into phase 8
(log correlation).

Conflict resolution — tempo.yaml datasource provisioning (search.filters):
- Took phase-7's complete 30-filter list as the base (it is the comprehensive
  set), preserved phase-8's tracesToLogs Loki-correlation block, and added
  phase-8's two unique filters (tx-type, ledger-hash). Verified the result is
  the full union (32 filters) with no filter dropped and no duplicate ids.
- Fixed a pre-existing dotted tag carried in from phase-7: the
  consensus-ledger-id filter used `xrpl.consensus.ledger_id`; the code emits
  the underscore key `consensus_ledger_id` (ConsensusSpanNames.h), so the
  dotted form was a dead filter. Now corrected.

Every span-scope filter tag verified to exist in the L1 *SpanNames.h key set.
Naming check green; 72 tests pass.

2efc932165 Merge branch 'pratik/otel-phase6-statsd' into pratik/otel-phase7-native-metrics
Bring the hardened OTel naming check (Rule E fix + 71 tests) and the phase 1-6
convention work forward into phase 7 (native metrics).

Conflict resolution:
- 05-configuration-reference.md: kept phase-7's native-OTLP metrics story
  (server=otel, /v1/metrics) over phase-6's superseded StatsD scrape job, in
  prose form (no code block).
- ordering.txt/loops.txt: regenerated via generate.py (not hand-edited).

087fcf54b1 docs(telemetry): fix dotted attribute keys in 06 Spans Produced tables
The two "Spans Produced" tables in 06-implementation-phases.md (added by the
Phase 4 consensus work) listed span ATTRIBUTE keys in the dotted
xrpl.consensus.* / ledger.seq / mode.old form. Convert them to the underscore
convention, matching the authoritative ConsensusSpanNames.h constants
(consensus_round, ledger_seq, consensus_mode, consensus_round_id,
consensus_ledger_id, consensus_result, mode_old/new, agree_count/disagree_count,
etc.). Span NAMES in column 1 stay dotted (rule 5). Every key verified to exist
as a constant in ConsensusSpanNames.h / SpanNames.h.

92bc0b24b8 docs(telemetry): drop volatile line numbers from Phase 4 span-catalog table
Phase 4 added a span catalog in `06-implementation-phases.md` listing the
source location for each consensus span. Line numbers `Consensus.h:707`,
`RCLConsensus.cpp:232/341/492/541/900` drift on every refactor and would
become stale PR after PR. Filename alone is enough for operators to
grep — the RCLConsensus.cpp spans are already unambiguous from the span
name itself.

44cdc8133e fix(telemetry): phase-6 dashboards — rename UIDs, add $node filter, drop line numbers
Phase-6 introduces ledger-operations, peer-network, and the five StatsD
dashboards. Align them with the rest of the chain:

- Rename dashboard UIDs from `rippled-*` to `xrpld-*` so the provisioned
  UIDs match the post-rename-script documentation (`docs.sh` rewrites
  .md but not .json, so the two drifted). Runbook references
  `xrpld-rpc-perf`, `xrpld-transactions`, etc., now the JSON matches.
- Add the `$node` template variable + `exported_instance=~"$node"` filter
  to every target in the five `statsd-*` dashboards. Mirrors the pattern
  already used by consensus-health, ledger-operations, and peer-network
  per the project rule that every dashboard must support per-node
  filtering.
- Strip `:<line>` (and `:NN-NN` range) suffixes from C++ file references
  in every dashboard panel description and in docker/telemetry/TESTING.md.
  Line numbers drift on every refactor; the filename alone is enough to
  grep.
- Replace stale `rpc.request` entries with the real emitted span names
  (`rpc.http_request`, `rpc.ws_upgrade`, `rpc.ws_message`, `rpc.process`)
  in TESTING.md so operators can copy-paste the filters and hit real
  traces.
- Also drop the `:706` line ref from the `StatsDCollector.cpp` callout
  in `06-implementation-phases.md`.

f3a095ab65 docs(telemetry): align Phase 1a plan docs with Phase 1b implementation
Phase-1a plan documents advertised OTLP/gRPC on port 4317 as the default
exporter, four unparsed [telemetry] config keys, and "Phase 4a Complete"
status with exit-criteria checkboxes marked done. Every downstream branch
through Phase 5 ships only OTLP/HTTP on port 4318 via OtlpHttpExporterFactory,
never parses the advertised keys, and the Phase 4 work is not yet delivered.

Fixes:
- 02-design-decisions.md: flip §2.1.1 SDK dependency recommendations to
  OTLP/HTTP (shipped) with OTLP/gRPC marked Future. Update §2.2 architecture
  diagram and text from OTLP/gRPC:4317 to OTLP/HTTP:4318. Rewrite §2.2.1 as
  "OTLP/HTTP (Shipped)" and §2.2.2 as "OTLP/gRPC (Future Work — Planned
  Upgrade)" with a concrete checklist (Conan dep, config parsing, factory
  branch, runbook/dashboard updates) for landing the gRPC transport later.
- 05-configuration-reference.md: drop the fabricated exporter/otlp_grpc key
  and the :4317 default from the sample config block and the options-summary
  table. Move trace_pathfind, trace_txq, trace_validator, trace_amendment
  into a new "Planned (not yet implemented)" table citing the phase that will
  add each one. Keep the example config minimal so copy-paste does not produce
  a silently-ignored stanza.
- 06-implementation-phases.md: reset Phase 4 Exit Criteria checkboxes from
  [x] to [ ] (Phase 4 is not shipped at Phase-1a time). Rename "Phase 4a
  Complete" to "Phase 4a Plan" and describe the work as future. Replace the
  broken forward link to Phase4_taskList.md (introduced in the Phase 2 PR)
  with a sentence pointing readers to where that spec will land. Renumber
  the final section 6.12 to 6.11 so it sits directly after 6.10; section 6.11
  ("Effort Summary") was intentionally removed in earlier edits.

8fb33b0818 feat(telemetry): add Phase 4 consensus tracing with SpanGuard API
Instrument the consensus subsystem with OpenTelemetry spans covering
the full round lifecycle: round start, establish phase, proposal send,
ledger close, position updates, consensus check, accept, validation
send, and mode changes.

Key design choices adapted from the original Phase 4 implementation
to the new SpanGuard factory pattern introduced in Phase 3:

- Add SpanGuard::hashSpan() for category-gated hash-derived trace IDs
  (consensus round spans share trace_id across validators via ledger hash)
- Add SpanGuard::addEvent() overload with key-value attribute pairs
  (used for dispute.resolve events during position updates)
- Add ConsensusSpanNames.h with compile-time span name constants
  following the colocated *SpanNames.h pattern from Phase 3
- Add consensusTraceStrategy config option ("deterministic"/"attribute")
  for cross-node trace correlation strategy selection
- Use SpanGuard::linkedSpan() for follows-from relationships between
  consecutive rounds and cross-thread validation spans
- Use SpanGuard::captureContext() for thread-safe context propagation
  from consensus thread to jtACCEPT worker thread

Spans produced: consensus.round, consensus.proposal.send,
consensus.ledger_close, consensus.establish, consensus.update_positions,
consensus.check, consensus.accept, consensus.accept.apply,
consensus.validation.send, consensus.mode_change

cbbd6ebee2 feat(telemetry): add Phase 6 StatsD metrics, ledger/peer spans, and expanded dashboards
Integrate the existing StatsD metrics pipeline (beast::insight) into
the OpenTelemetry observability stack and add new trace spans for
ledger build/store/validate and peer proposal/validation receive.

Phase 5b — Ledger, peer, and transaction spans:
- Add ledger.build span with close time attributes in BuildLedger.cpp
- Add tx.apply span with tx_count/tx_failed in BuildLedger.cpp
- Add ledger.store and ledger.validate spans in LedgerMaster.cpp
- Add peer.proposal.receive span with trusted attribute in PeerImp.cpp
- Add peer.validation.receive span with ledger_hash, full, trusted
  attributes in PeerImp.cpp
- Add ledger-operations and peer-network Grafana dashboards

Phase 6 — StatsD metrics integration:
- Add StatsD UDP receiver (port 8125) to OTel Collector
- Add 5 StatsD Grafana dashboards: node health, network traffic,
  overlay traffic detail, ledger data sync, RPC pathfinding
- Add 09-data-collection-reference.md cataloging all metrics/spans
- Update existing dashboards with new span panels
- Expand telemetry runbook and integration test script
- Add codecov exclusions for telemetry modules

c585d9b66c docs(telemetry): add deterministic TX trace ID design (Task 3.9)
Add trace_id = txHash[0:16] strategy so all nodes handling the same
transaction independently produce spans under the same trace_id,
combined with protobuf span_id propagation for parent-child ordering.

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.

913a4b794c docs: correct OTel overhead estimates against SDK benchmarks
Verified CPU, memory, and network overhead calculations against
official OTel C++ SDK benchmarks (969 CI runs) and source code
analysis. Key corrections:

- Span creation: 200-500ns → 500-1000ns (SDK BM_SpanCreation median
  ~1000ns; original estimate matched API no-op, not SDK path)
- Per-TX overhead: 2.4μs → 4.0μs (2.0% vs 1.2%; still within 1-3%)
- Active span memory: ~200 bytes → ~500-800 bytes (Span wrapper +
  SpanData + std::map attribute storage)
- Static memory: ~456KB → ~8.3MB (BatchSpanProcessor worker thread
  stack ~8MB was omitted)
- Total memory ceiling: ~2.3MB → ~10MB
- Memory success metric target: <5MB → <10MB
- AddEvent: 50-80ns → 100-200ns

Added Section 3.5.4 with links to all benchmark sources.
Updated presentation.md with matching corrections.
High-level conclusions unchanged (1-3% CPU, negligible consensus).

Also includes: review fixes, cross-document consistency improvements,
additional component tracing docs (PathFinding, TxQ, Validator, etc.),
context size corrections (32 → 25 bytes).

7e149f7773 refactor(telemetry): remove residual Jaeger references across chain
Fix remaining Jaeger references that accumulated across intermediate
branches in the stacked PR chain. These were in files modified by
multiple phases where the per-branch fixes didn't cover all additions.
