The config template wrote each node's log to a lowercase node{N} directory
while setting service_instance_id=Node-{N}. The collector takes the node name
from the log file's parent directory and stamps it as the Loki
service_instance_id label, so the logs carried a name no trace or metric
shared and nothing joined. Use Node-{N} and state the rule.
The template also set log_level to warning. Nothing in the pipeline filters on
severity; the constraint is that a log line carries trace context only when it
is emitted inside an active span. At warning the only such statements in the
consensus accept span are a catch path a healthy round never takes and a
periodic censorship warning. At info the CNF Val / CNF buildLCL pair writes one
line per accepted ledger, which is what makes this test's Step 1 findable.
Grafana 13 offers the link per span, labelled "Logs for this span", in the
span's Links row — not per trace. Fix the step and the expected-results row.
The example log line quoted a message that does not exist. The real in-span
RPC statement logs at debug, so the severity code is DBG; say which line to
look for under each test, since Test 2 now logs at info.
Drop the reference to workload/validate_telemetry.py: that file is not part of
this branch, and its instant-endpoint call uses seconds, so the nanoseconds
claim applied only to query_range.
