Verification: local server HTTP end-to-end (2026-10-12)

Subprocess python -m agent_sandbox.server serve on 127.0.0.1 (ephemeral port). Checks are a separate HTTP client, plus a raw socket for the websocket upgrade. Handlers were not called in-process. PYTHONPATH=server-sdk/src, ABX_SERVER_ENABLED_GROUPS=agents, fake codex and qwen on PATH. No server source edits.

Command

cd python-sdk/e2e
PYTHONPATH=../server-sdk/src python3 -m pytest test_server_http_e2e.py --noconftest -ra -v

Interpreter: Python 3.12.3, pytest 9.1.1. --noconftest avoids the cloud suite skip that fires when E2B_API_KEY is unset.

Counts

18 passed, 0 failed, 0 skipped (0.46s).

GET /v1/responses with Upgrade: websocket returned 101 and completed a response.create frame (not the 400 skip). Multipart POST /v1/files returned 200 (not rejected).
