d2c7a00584 docs(telemetry): note service.name on metrics and collector tier tagging
- 05-configuration-reference: service_name now applies to metrics as well
  as traces (service.name resource attribute).
- 07-observability-backends: document that collector enrichment includes
  deployment-tier tagging (deployment.environment + fallback
  xrpl.network.type) for filtering one Grafana stack by tier.

190b9470a4 docs(telemetry): fix xrpl.network.type value (standalone → unknown)
The network-type label is derived from [network_id] in TelemetryConfig.cpp;
unmapped/unset IDs fall through to "unknown", not "standalone". Align the
design-doc resource-attribute table with the code and cfg example.

c3ccde3e39 docs(telemetry): document the span-attribute naming rules
State the rules so they stay consistent across code, collector, Tempo,
dashboards, and docs:

- Per-span-unique field -> bare name (the span name carries the domain).
- Same concept on more than one span -> ONE shared key, reused verbatim and
  distinguished by span name, never tagged with the emitting workflow
  (e.g. ledger_hash, full_validation, proposal_trusted/validation_trusted).
  Defined once in the base SpanNames.h and re-exported by each domain header.
- Collision qualifier <domain>_<field> only to separate DIFFERENT concepts that
  share a word, or the OTel-reserved status key (rpc_status, consensus_state).
- Dotted xrpl.<...> is reserved for resource attributes (xrpl.network.*).

Updates CONTRIBUTING.md (permanent home) and OpenTelemetryPlan §2.3.3.

d5efd657ae Merge branch 'pratik/otel-phase1a-plan-docs' into pratik/otel-phase1b-telemetry-infra
Bring the phase-1a code-sample cleanup into phase-1b.

Phase 1a deleted the two code-sample docs (04-code-samples.md,
POC_taskList.md) and stripped C++/config code blocks from the remaining
plan docs, replacing them with prose summaries and pointers to the real
source/config files.

Conflict resolution:
- 04-code-samples.md, POC_taskList.md: deletion wins (phase-1b's SpanGuard
  rewrites of these files are intentionally dropped).
- 03/05/OpenTelemetryPlan.md: took phase-1a's code-block-free prose, but
  kept phase-1b's accurate descriptions of the real telemetry code
  (DiscardFlag.h, FilteringSpanProcessor, SpanGuard factory methods, and
  the corrected file-count/file-list tables).
- presentation.md left untouched.

e9cb9421ef Merge branch 'pratik/otel-phase1a-plan-docs' into pratik/otel-phase1b-telemetry-infra
Bring the span attribute naming convention (phase 1a) into phase 1b.

Conflict resolution kept phase-1b's SpanGuard-based workflow and applied
the underscore naming convention to all non-code-sample text:
- Converted prose, tables, Mermaid labels, and TraceQL/PromQL query
  references across the plan docs to the underscore form.
- Converted the two @code attribute-key examples in Telemetry.h
  (command, tx_type).
- Left the code-sample files (04-code-samples.md, POC_taskList.md) and
  03-implementation-strategy.md code blocks at the phase-1b version; the
  code-sample docs are slated for removal on phase-1a.

c0272f1314 docs: Add span attribute naming convention (OTel phase 1a)
Establish the single, authoritative naming convention for OpenTelemetry
span attribute keys so the code, collector, Tempo, dashboards, and docs
stay in sync.

- CONTRIBUTING.md: new "Telemetry span attribute naming" section under
  the Style guide as the permanent, canonical home for the rules.
- OpenTelemetryPlan/02-design-decisions.md: new section 2.3.3 stating the
  decided convention as design, and section 2.4 attribute schema realigned
  to the underscore form (exact key spelling defers to the *SpanNames.h
  constants).
- Sweep the remaining plan docs: convert dotted xrpl.<domain>.<field> span
  attribute keys to the underscore form; leave span names and the
  OTel-standard service.*/http.* and xrpl.network.* resource keys dotted.

5598b0eac7 docs(telemetry): fix head sampling at 1.0, remove configurable ratio
Document that head sampling is intentionally fixed at 100% and no longer
exposes a sampling_ratio config knob. A per-node ratio let nodes make
divergent keep/drop decisions for the same distributed trace, producing
broken/partial traces; pinning at 1.0 with a ParentBased sampler keeps
decisions coherent across the network. Volume reduction is delegated to
collector-side tail sampling.

fe13359024 docs(telemetry): enable peer tracing by default in plan docs
Flip trace_peer default false->true across the Phase-1a plan docs and
correct the rationale: peer spans record only peer_id (numeric local
connection id) plus trust/ledger metadata, never IP addresses or public
keys, so the 'includes addresses' caveat was inaccurate. The high-volume
note is retained.

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.

e9c5c3520e fix(telemetry): address Phase 1b code review findings
Redesign SpanGuard with pimpl idiom to hide all OpenTelemetry types
from public headers. Add global Telemetry accessor so SpanGuard factory
methods work without explicit Telemetry references. Add child/linked
span creation and cross-thread context propagation. Update plan docs
to reflect macro removal in favor of SpanGuard factory pattern.

Plan documents referenced Application.h and app_ for getTelemetry()
but the codebase now uses ServiceRegistry as the interface. Updated:

- POC_taskList.md Task 4: target ServiceRegistry.h not Application.h,
  correct config file path and constructor pattern
- 04-code-samples.md: fix overlay() -> getOverlay(), rewrite JobQueue
  sample to reflect actual architecture (no app_ member)
- 03-implementation-strategy.md: fix file impact table path

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).
