Sandbox Environment

Devin runs `pytest tests/` in the sandbox terminal. Test fails with a traceback spanning 40 lines.

Capture full stdout + stderr + exit code into the session log; surface the traceback verbatim to Devin's reasoning context — do not truncate to first N lines silently. If output exceeds a documented per-command cap, signal truncation with an explicit marker so Devin re-runs with --tb=short or pipes…

Devin's sandbox browser hits a Cloudflare captcha while logging into a SaaS dashboard the task depends on.

Captcha is a human-handoff trigger per the surface map's explicit out-of-scope: Devin must pause, post a clarification asking the operator to take over the browser tab, and not attempt automated bypass. Resume only after operator signals completion via message.

Repo needs `pnpm install` and a database migration to run before Devin can exercise tests.

Encode environment setup in the repo's machine_setup commands or the session setup_commands field so Devin runs them before opening the workspace — do not rely on Devin to infer them from README on every session. Verify setup exit code and abort early on failure.
