Greptile Summary

This PR addresses flaky CCA (create-cedar-app) E2E tests by making post-test directory cleanup more resilient: it adds a brief delay and swallows errors when git may still be writing to .git/objects after the generator exits.

• e2e.test.ts: Replaces the single fs.rm call with a removeGeneratedApp helper that retries up to 3 times with 500 ms back-off, warns on final failure, and also tightens the unknown-options error handler with an explicit type guard instead of the loosely typed catch (p).
• Six Tcl/Expect shell scripts: Consolidates cleanup into a single unconditional after 500; catch {exec rm -rf $projectDirectory} block before the exit-status check, making cleanup best-effort and independent of the test outcome in all scripts.

Confidence Score: 5/5

All changes are confined to test cleanup code; no production logic is touched and the fix correctly addresses the identified race condition.

The changes are narrow and well-understood: a retry wrapper around directory removal in the TypeScript test, and equivalent best-effort cleanup in the shell scripts. No application logic is modified, and the Tcl catch/after usage is correct.

No files require special attention.

Important Files Changed

Filename	Overview
packages/create-cedar-app/tests/e2e.test.ts	Adds retry logic for post-test cleanup and tightens type safety in the unknown-options error handler — clean, targeted fix.
packages/create-cedar-app/tests/e2e_prompts.sh	Moves cleanup before the exit-status branch, adds 500 ms delay and wraps rm -rf in catch to make cleanup best-effort; correct Tcl/Expect usage.
packages/create-cedar-app/tests/e2e_prompts_git.sh	Same best-effort cleanup pattern as e2e_prompts.sh — consistent across all prompt scripts.
packages/create-cedar-app/tests/e2e_prompts_m.sh	Same best-effort cleanup pattern applied uniformly.
packages/create-cedar-app/tests/e2e_prompts_node_greater.sh	Same best-effort cleanup pattern applied uniformly.
packages/create-cedar-app/tests/e2e_prompts_overwrite.sh	Same best-effort cleanup pattern; note this script expects exitStatus 1 for success, which is preserved correctly.
packages/create-cedar-app/tests/e2e_prompts_ts.sh	Same best-effort cleanup pattern applied uniformly.
