# Diagnostics e2e stack.
#
# The collector service runs in its own container with the bundles dir
# bind-mounted from the host so the harness can read the finalized
# tarball. Both the collector and the pp processes use the host network
# namespace, so the stage children (spawned by `pp-smoke-run` via
# `docker-gpu-node.sh`) share localhost reachability with the
# collector — `SWACTOR_DIAG_COLLECTOR_URL=http://127.0.0.1:9080` works
# uniformly from every actor in the run.
#
# The host network choice mirrors the existing `docker-e2e.sh` shape:
# pp-smoke-run runs on the host (orchestrator) and each
# `pp-gpu-node` runs in its own container under `--network host`. The
# collector container just adds one more service to that arrangement.
#
# Used by `scripts/docker-diag-e2e.sh`. Direct `docker compose up`
# without the wrapper is fine for manual collector-only operation, but
# the orchestrator-side wiring (env-var injection, bundle assertions)
# lives in the script.
