When `tools` is present in the request, DS2API performs anti-leak handling:
1. Toolcall feature matching is enabled only in **non-code-block context** (fenced examples are ignored)
2. Once high-confidence features are matched (`tool_calls` + `name` + `arguments/input` start), `delta.tool_calls` is emitted immediately
3. Confirmed toolcall JSON fragments are never leaked into `delta.content`
4. Natural language before/after toolcalls keeps original order, with incremental argument output supported
2. In `responses` stream mode, tool calls follow official item lifecycle events (`response.output_item.*`, `response.content_part.*`, `response.function_call_arguments.*`)
3. Unknown tool names (outside declared `tools`) are rejected and are not emitted as valid tool calls
4. `tool_choice` is enforced on `responses` (`auto`/`none`/`required`/forced function); required violations return HTTP `422` (non-stream) or `response.failed` (stream)
5. Confirmed toolcall JSON fragments are never emitted as valid tool call events unless they pass policy checks
