 - Renderer 只消费共享的产品中立 project/Conversation/Snapshot/Patch DTO，并经 `src/lib/host-api.ts` 或 `src/lib/api-client.ts` 访问 Main。Pi RPC、event、Provider credential 和本地 runtime 路径保持 Main-private。
 - accepted/uncertain Coding mutation 不得自动重放；RPC confirmation timeout 后仍保留 target run permit、process ownership 和 background lease，直到迟到 success/failure/exit/abort 权威收敛。其他 Conversation 必须继续可用。
 - selected Provider credential 只投影到目标父逻辑线程的内存 credential store 或目标 child 进程；跨账号模型变化必须重建目标逻辑线程。确定性 Works user-context 缺失是 Provider-auth failure：失效缓存 credential、fail fast、固定脱敏提示，不得归类为 Pi crash。
+- Works 下发的 per-model reasoning capability 是可选 Main-owned metadata，不是
+  Renderer 或 one-api 的权威。存在时只接受受支持的安全形状并覆盖目标模型的
+  本地 effort map；缺失时移除旧 override 并使用已验证本地 profile。`off` 在 Pi
+  wire 上表示 `thinking.type=disabled` 且不发送 `reasoning_effort`，启用档位保持

 - Guided Hotspot Binding is implemented behind a Main-owned capability that is true by default; exact `NIANCODE_AI_HARDWARE_GUIDED_HOTSPOT_BINDING=0` disables it, while capability-read failure falls back to direct six-digit Binding. The guided state is process-local, opener failures expose only the same fixed address for manual copy, and Binding conflicts refresh the safe account overview.
 - Robot hotspot scanning and connection are local Main operations that return before Works credentials/upstream access. Renderer may submit only an opaque candidate ID from the latest bounded scan; Main alone filters open printable `Xiaozhi-*` SSIDs, performs platform association, and verifies the exact current SSID.
 - Hotspot discovery and connection do not authenticate a Robot. BSSID, interface/profile details, native diagnostics, location data, and Wi-Fi credentials never cross the Main boundary; permission or platform failure keeps the system-settings/manual path available.
