The comment said "It parses; it does not prove a sample arrives",
which understates the gap in the direction that matters: it reads as
if a green build proves the collector *starts* and only runtime
delivery is unverified.
Measured while probing ingest-auth options for #3283: `otelcol
validate` ACCEPTS a receiver naming an auth extension that is absent
from the build, and the collector then dies at startup with `Failed
to start component`. So the check does not prove this config starts
at all.
Comment-only; no evaluated config changes.
Refs #3283.
