The internal border-drawing renderer now wraps each line through a new formatting step before writing it

What

The internal function that draws borders in Claude Code's terminal interface now takes an extra parameter, which is threaded through a new wrapping call applied to every border line before it's written to the screen, instead of writing the raw text directly.

Why

This is an internal rendering change with no described user-facing effect on its own; it likely supports some additional styling or processing of border output, but what that is isn't specified.

How sure we are
Something disagreesSomething we can check disagrees with this entry, or the writer said they could not settle it.
The writer flagged doubtThe finding doesn't say what the new wrapping call actually does or why the extra parameter was added.
