- environments/gsm8k_agent_env.py: Math reasoning with Python REPL tool
- Subclasses HermesAgentBaseEnv (proper tools= parameter, not ICL)
- Uses ATROPOS_SERVER_* env vars from .env
- Hermes tool call parser, configurable per model
- Math verification via math_verify with string fallback
- Tested: process mode works, both trajectories scored 1.0
- Updated memory bank with consolidation plan:
- environments/ is the canonical env system (proper tool calling)
- atropos/backends/ kept as sandbox infrastructure
- atropos/agent/ and atropos/envs/agent_env.py marked for removal
