The closing fence logic in protected ranges was relaxed to allow an info string on the closing fence, accommodating models that place the next protocol marker on the same line as the fence terminator. A removed debug test for wrapper-end parsing was dropped as it no longer reflects the corrected behaviour.

In the JSON repair function, change the handling of strings that are cut off mid-value: instead of appending a closing quote and potentially creating a silently truncated argument, return the original string unchanged. Refactor the name resolution logic to allow stripping class-name suffixes up to twice, enabling matching of names like `TodoTool_tool`. Delete a debug test that was left in the stream test module.

Also add `#[must_use]` annotations to two public functions in the render module and fix a raw string literal in a test. These changes remove unnecessary `self` parameters and improve code consistency without altering behaviour.
