+## Active Default Routing Baseline (2026-03-18)
+
+Current `opencode` default-model routing baseline:
+
+- `mac-5`
+  - default model: `opencode/minimax-m2.5-free`
+  - rationale: the minimax free cloud route already passed direct + ACP minimal validation and avoids the timeout-prone local `oMLX` ACP path
+- `mac-6`
+  - provider label: `vllm`
+  - base URL: `http://100.64.0.5:8000/v1`
+  - model id: `Qwen3.5-27B`
+  - default model string: `vllm/Qwen3.5-27B`
+- `mac-7`
+  - provider label: `vllm`
+  - base URL: `http://100.64.0.5:8000/v1`
+  - model id: `Qwen3.5-27B`
+  - default model string: `vllm/Qwen3.5-27B`
+
+Superseded assumption:
+
+- Do not continue to describe the cluster rule as "each machine defaults to its own local model" for `opencode` ACP.
+- That older description was true for the earlier `oMLX`-first phase but is no longer the active default-policy baseline.
+
+Validation snapshot:
+
+- `mac-6` ACP test result: `MAC6_VLLM_ACP_OK`
+- `mac-7` ACP test result: `MAC7_VLLM_ACP_OK`
