Norma v0.4.6 frames tool output between nonce-tagged markers, so the model
reads it as data. ARTEX passes that option from the environment: 1, true or
on enable it (case and surrounding spaces ignored); unset or anything else
keeps it off, which is the default. Nothing changes unless the variable is set.
The option is wired into the four agentcore.Options builders that set
ToolOutputDir: worker, planner, chat and the main agent. .env.example
documents the variable, commented out, with a note to test it on a local
target before enabling it in production.
Not included: docker-compose.yml does not pass the variable to the artex
service, so it has no effect under compose until it is listed there.
