Diagnosis for the exact linked job/attempt: run 35034454523, job 104603871735, Smoketests (Windows 2/4), attempt 1.

This was PR #5816 (rekhoff/test-of-staging-windows-runners) at head a08b98bed59784849f33c17d92bacb42c79c89a2. Checkout, Rust setup, .NET setup, Node/pnpm setup, Emscripten setup, psql install, artifact download, and smoketest support extraction all completed. The job failed in Run smoketest partition (Windows).

The only failed test was standalone::default_module_clippy::test_basic_rs_template_clippy. The test panicked because it expected the basic-rs template to have no clippy warnings, but the clippy command itself could not run:

Template 'basic-rs' should have no clippy warnings:
stderr: error: 'cargo-clippy.exe' is not installed for the toolchain '1.93.0-x86_64-pc-windows-msvc'.
help: run `rustup component add clippy` to install it

Root cause for this exact attempt: the Windows runner/toolchain was missing the clippy component for 1.93.0-x86_64-pc-windows-msvc. This is a runner/toolchain setup flake, not a basic-rs template warning.

Suggested updated title: CI flake: Windows smoketest template clippy fails because cargo-clippy is missing

Duplicate analysis:

• Similar ticket: CI flake: Smoketests (Windows 4/4) / standalone::default_module_clippy::test_chat_console_rs_template_clippy #5944, same run/attempt and same missing cargo-clippy.exe mechanism, but for chat-console-rs in Smoketests (Windows 4/4).
• Duplicate searches for cargo-clippy.exe not installed, rustup component add clippy, default_module_clippy, and the exact template panic only found CI flake: Smoketests (Windows 2/4) / standalone::default_module_clippy::test_basic_rs_template_clippy #5943/CI flake: Smoketests (Windows 4/4) / standalone::default_module_clippy::test_chat_console_rs_template_clippy #5944 in this repository. No older public Test Flakes ticket was close enough to mark as the top duplicate.

Top duplicate candidate: none. Similar ticket #5944 exists, but it is a same-run sibling rather than an older canonical duplicate. Leaving this open.
