 ### Fixes
 
+- Windows installer: fail Git checkout installs when `pnpm install` or `pnpm build` fails instead of writing a wrapper to a missing CLI build.
 - Agents: keep parallel OpenAI-compatible tool-call deltas in separate argument buffers so interleaved tool calls no longer corrupt streamed arguments. (#82263) Thanks @luna-system.
 - Memory/doctor: report missing or unusable QMD workspace directories as workspace failures instead of generic binary failures. (#63167) Thanks @sercada.
 - Debug proxy: record CONNECT client-socket errors and destroy the paired upstream socket so abrupt client disconnects no longer leak tunnel resources. (#82444) Thanks @SebTardif.
