claude is responding with garbage and an API error:
 API Error: Claude Code is unable to respond to this request, which appears to violate our Usage Policy (https://www.anthropic.com/legal/aup). Please double press esc to
edit your last message or start a new session for Claude Code to assist with a different task. If you are seeing this refusal repeatedly, try running /model
claude-sonnet-4-20250514 to switch models.

there appears to be significant model corruption - this has happened in two simultaneous sessions, both running Opus 4.6 1M.
