+## 2026-02-12 - 1.2.1 - fix(rust-binary-locator)
+auto-fix missing execute permission for located Rust binaries
+
+- If a located binary exists but lacks the execute bit, attempt to chmod it to 0o755 and treat it as executable.
+- Logs an info message when the auto-fix is applied: 'Auto-fixed missing execute permission on: <filePath>'.
+- Addresses cases where npm/pnpm installs remove the execute permission from bundled binaries.
+
 ## 2026-02-11 - 1.2.0 - feat(rustbridge)
 add streaming responses and robust large-payload/backpressure handling to RustBridge
