## Why Sandbox wrappers replaced the process launch command and did not carry an `ExecParams.arg0` override through to the inner process. ## What changed - Route sandboxed Unix launches with a custom `arg0` through a helper mode that re-execs the requested program with the override. - Expose the helper executable to the filesystem sandbox and dispatch its mode from Codex and exec-server test binaries. ## Testing Add coverage for the prepared sandbox command and an end-to-end remote process that verifies both the custom `arg0` and filesystem restrictions.

//! Minimal exec-server fixture for Bazel-only integration tests.

|
//!
|
|
//! Linking only exec-server avoids depending on the full Codex CLI binary
|
|
//! when a test only needs a WebSocket executor endpoint. It handles the arg0
|
|
//! helper mode because sandboxed process requests re-exec this binary.
