      "description": "Identifies TWO INDEPENDENT escape layers, not one: (a) YAML parsing — single-quote the regex string (or use a block scalar) so backslashes aren't consumed by YAML's double-quoted-string parser; and (b) the OpenTelemetry Collector's envprovider — regex backreferences `$1` / `$2` must be written `$$1` / `$$2` in values.yaml because at collector startup the envprovider expands `$...` references, and `$$` is the literal-`$` escape. Correct attribution matters: Helm's template engine passes `$` through unchanged, so an answer that blames Helm for the `$$` rule is incorrect even if its fix (`$$1`) is right. Recommends running `helm template ... -f values.yaml` before `helm upgrade` to verify the rendered OTTL. A response that fixes only the YAML quoting without the `$$` escape, that blames the regex as syntactically invalid, that attributes the `$$` rule to Helm rather than the collector's envprovider, or that tells the user to rewrite the regex without backreferences, is a FAIL.",
