Sync #50: real WSL terminal check fails at "Exercise real WSL launch and paste" #51

On sync PR #50 (head 5aafdd009f, merged as 7d33e616ae), the real WSL terminal / wsl-terminal check failed. Job:

• "Exercise real WSL launch and paste" exited 1;
• "Require all nine WSL executions" exited 1;
• the screenshot upload found no test-results/**/windows-inline-*.png.

The job uploaded its traces as the windows-wsl-terminal-traces artifact (ID 12506323842).

On #47 this check was skipped, so this is its first run on a sync PR since the 2026-10-22 port. The automation could not read the step's log from minidev-alex1, so the failure is unattributed. It is not ruled out as fork-caused: the fork's resume work (#30) touches WSL panes (wsl: relay ids, a user-ended Claude session carried through the WSL relay).

To do

• Read the traces artifact and the step log.
• If upstream's own code fails here, note it and close this issue.
• If a fork line is involved, fix it through a PR into swaplabs/main.
