 ### 3. Run
 
+#### Benchmark with unreleased aforge-v2
+
+Build aforge-v2 once, point AgentField at it, and select the runtime. No SWE-AF
+code or prompt changes are required:
+
+```bash
+cd /path/to/aforge-v2
+go build -o /absolute/path/to/bin/aforge ./cmd/aforge
+
+export OPENROUTER_API_KEY=sk-or-v1-...
+export AFORGE_BIN=/absolute/path/to/bin/aforge
+export SWE_DEFAULT_RUNTIME=aforge
+export SWE_DEFAULT_MODEL=openrouter/deepseek/deepseek-v4-flash-0731
+python -m swe_af
+```
+
+The draft pins the exact AgentField harness commit used for these benchmarks.
+Replace that source pin with the released SDK version before merging. The
+existing Docker image does not bundle the unreleased aforge-v2 binary; add it
+to the container or run the node on the host until Aforge publishes an
+installable artifact.
+
 ```bash
 af                 # starts AgentField control plane on :8080
 python -m swe_af   # registers node id "swe-planner"
