The .loose() method doesn't exist in Zod - replace with .passthrough() to allow additional properties in the anthropicStreamEventSchema. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
Since thinking blocks are an Anthropic-specific feature, the tests should use an Anthropic model instead of gpt-4o for accuracy and clarity. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
