Result: ⚠️ partially-verified

Verification: Isolated verification observed failures that were not classified as caused by this PR: Wrapper idempotence and startup-global smoke checks.

Summary: On Python 3.13.16, the targeted shell-integration file reported **11 passed**, including the PR’s new prompt-conversion test. Additional checks confirmed idempotent wrapping, single prompt conversions, and Python 3.11 compatibility. An actual-PS1 smoke check failed because this environment runs under WSL, where pythonrc deliberately suppresses sys.ps1; existing prompt-rendering tests also return early there. Verification is partial, with no observed PR-caused failure.

Test runs: 3 passed, 1 failed
