# QUARANTINED pending a @copilotkit/react-core release. gen-ui-interrupt /
# interrupt-headless fail turn-2 on a useInterrupt/useHeadlessInterrupt
# RESUME-PATH hook bug in @copilotkit/react-core/v2: backend resumes + streams
# (HTTP 200) but the frontend never appends the confirmation assistant bubble,
# so the harness DOM settle-check times out. Fix is a published-package change
# (out of scope here); honestly marked not-supported (skipped-incapable, not
# green, not red) rather than a regression. Demos remain wired below.
