# Blocker S00-030

- Original task: S00-028
- Root task: S00-005
- Reporter: auto-ci-cd-211cf3a2bd08
- Role: ci-cd
- Original owner: auto-ci-cd-211cf3a2bd08
- Waits for user/external condition: True

## Cause

S00-028 cannot independently validate project filesystem sandbox: installed Codex sandbox exits before command execution because the app-server socket directory must be user-owned with mode 0700. Host socket repair is outside launcher arguments scope.
Automatic blocker limit reached; explicit external resolution required.

## One remediation outcome

Coordinator provides a valid private app-server socket environment and a bounded no-model Codex sandbox probe executes with project write restrictions intact.

## Evidence / reproduction

codex -c 'sandbox_mode="workspace-write"' -c sandbox_workspace_write.network_access=true sandbox -- python3 -c '<synthetic project write/read/remove probe>' exits 1: error building bubblewrap command: app-server socket directory must be a user-owned directory with mode 0700. See state/evidence/S00-028-auto-ci-cd-211cf3a2bd08.md.

The reporting agent must stop now. A new agent implements only S00-030.
