Dockerfile

# ── GraphStrike — OpenEnv Environment Server ─────────────────────────────────
# This Dockerfile runs the environment server (FastAPI + Gradio UI + episodes).
# No training loop, no AWS credentials required.
#
# Used by:  openenv push / HuggingFace Spaces deployment
# Port:     7860 (HF Spaces default — configurable via PORT env var)
#
# For local training (Qwen3 + Reflexion + Hybrid Policy), use server/Dockerfile.
# ─────────────────────────────────────────────────────────────────────────────

# Server only — the training loop is NOT started here.
# Judges evaluate the environment via the API endpoints:
#   GET  /health      → liveness check
#   GET  /tasks       → available tasks + action schema
#   POST /reset       → start an episode
#   POST /step        → take an action
#   GET  /grader      → get normalised score after SUBMIT
#   POST /baseline    → run the rule-based agent on all 3 tasks
