Wire the apply-pipeline stage spans (tx.preflight, tx.preclaim,
tx.transactor) added on phase-3 through the observability stack so the
spanmetrics connector produces per-stage RED metrics without any native
instruments.
- collector: add the `stage` dimension to the spanmetrics connector so
the three stages split into separate metric series (3 bounded values).
- dashboard: add a "Tx Apply Pipeline" section to transaction-overview
with rate, p95 latency, and failure-rate panels grouped by stage, plus
a `stage` template variable. Panels follow the existing config (node
filter, exported_instance legends, Title Case, axis labels).
- The failure panel filters ter_result != tesSUCCESS rather than span
status, because a failing ter code completes the span normally — only
thrown exceptions set an error status. This matches the existing
"Transaction Results by Type" panel convention.
- docs: document the spans, attributes, and stage dimension in the data
collection reference and runbook, including the sampling caveat that
span-derived metrics inherit tracer head-sampling and undercount at
sampling_ratio < 1.

The spanmetrics connector dimension was `xrpl.consensus.mode`, but the code
emits the span attribute under the bare key `consensus_mode` (matching every
other dimension after the Phase 6 rename). The mismatch left the
`xrpl_consensus_mode` Prometheus label empty, so the Consensus Health
"Consensus Mode Over Time" panel and the `$consensus_mode` template variable
(which filters every panel) matched no live series.
- otel-collector-config.yaml: dimension `xrpl.consensus.mode` -> `consensus_mode`
- consensus-health.json: 11 label refs `xrpl_consensus_mode` -> `consensus_mode`
(the `$consensus_mode` Grafana variable name is unchanged)
- telemetry-runbook.md: refresh the stale spanmetrics label table to the bare
names actually emitted (command/rpc_status/consensus_mode/local/
proposal_trusted/validation_trusted), fix dotted->bare attribute names in
span tables and TraceQL examples (tx_hash, ledger_seq, consensus_round_id,
consensus_ledger_id, consensus_round, tx_id event attr), correct the
consensus_round_id query to int (not quoted string), and fix the
load_type value query ("exception_rpc" -> "exceptioned RPC").
Verified against the live stack: Tempo span tags confirm bare attribute keys
(consensus_mode, ledger_seq, tx_hash, ...); the populated xrpl_consensus_mode
series in Prometheus is stale retained data from an older build.

Resolve runbook conflict: keep both phase 6 ledger/peer span tables
AND new insights/sample queries section from the enrichment work.

Adds comprehensive "Insights and Sample Queries" section showing operators
what questions they can answer with the newly-added span attributes:
- Transaction workflow analysis (filter by tx_type, fee, ter_result)
- TxQ health (txq_status, ledger_changed)
- RPC debugging (is_batch, request_payload_size, load_type)
- PathFinding performance (dest_currency, num_source_assets)
- Consensus health (consensus_state, is_bow_out, disputes_count)
- Cross-subsystem correlation examples
Also updates all span reference tables with the new attributes.

- RPC Spans table: `rpc.request` was documented but the code actually emits
`rpc.http_request`. Listed the actual emitted names
(`rpc.http_request`, `rpc.ws_upgrade`, `rpc.ws_message`, `rpc.process`)
and their parent/child relationship.
- Drop `:<line>` suffixes from Source File columns in both RPC and
Transaction span tables. Line numbers drift with every refactor; the
filename is enough for operators to grep.
- Summary table: replace the never-emitted `rpc.request` row with the real
entry points so `span_name=` filters in PromQL / TraceQL match.
Update 31 attribute references in telemetry-runbook.md to match the
simplified naming: drop xrpl.<domain>. prefix on per-span attrs, use
domain-qualified names for collisions (rpc_status, consensus_state,
etc.), and unify cross-domain refs (xrpl.ledger.seq, xrpl.tx.hash).

- Fix use-after-free: extract gauge callback to static function and call
RemoveCallback in ~OTelGaugeImpl() before unregistering from collector
- Use memory_order_acq_rel on callHooks() debounce CAS for proper
happens-before relationship between hook invocations
- Add explicit 2s timeout to ForceFlush() in destructor to prevent
blocking indefinitely when OTLP endpoint is unreachable at shutdown
- Add OTLP receiver to metrics pipeline so native OTel metrics from
xrpld are actually received by the collector
- Remove stale health check port from docker-compose (extension was
removed from collector config)
- Clarify fallback docs: StatsD path requires re-enabling receiver/port
- Fix comments: Counter uses uint64_t not int64_t, gauge clamps to
[0, INT64_MAX] not [0, UINT64_MAX]
