Unable to download required artifacts (plc_wrapper_main and DREAMPlace tarball) from GCS (HTTP 403)

[gey16]

Hi!

I am trying to set up circuit_training and hit a blocker downloading required artifacts from the documented GCS paths.

Date tested: February 19, 2026 (UTC)
Environment: Docker on macOS arm64 host (linux container)

Repro

curl -sS -D - -o /dev/null \
  https://storage.googleapis.com/rl-infra-public/circuit-training/placement_cost/plc_wrapper_main

curl -sS -D - -o /dev/null \
  https://storage.googleapis.com/rl-infra-public/circuit-training/dreamplace/dreamplace_python3.9.tar.gz

Result
Both return HTTP/2 403 with:
AccessDenied: Anonymous caller does not have storage.objects.get ... (or it may not exist)

I also confirmed /usr/local/bin/plc_wrapper_main becomes a 298-byte XML file when downloaded via Docker, causing:
OSError: [Errno 8] Exec format error.

Request

1. Could you clarify the supported path for external users?
2. Are these artifacts intentionally private now?
3. If access is required, what is the process to obtain it?

Thanks! Grace
