A long source text now opens in a reader of its own. When an argument is built from a substantial piece of writing — an essay, a chapter, a long article — the Source Text panel no longer pours the whole thing into the narrow sidebar, where reaching the end of it could take fifty screens of scrolling. It now shows the citation, how many words the text runs to and how many of its passages the argument traces back to, and an "Open Origin Document" button. The button opens the text full-screen, at a comfortable reading width, over the argument: closing it puts you back exactly where you were.

In that reader you can walk the traced passages one at a time, forwards and backwards in the order they appear in the writing, with each step telling you which passage of how many you are on — so you can see how much of the source the argument actually draws on, and where it goes untouched. You can also search the text for a word or phrase and move between the places it occurs; a phrase that is not there says so.

A passage cue on a premise or claim leads to the same place. Its "View full text" button opens the reader already scrolled to that passage, with the passage lit. Short source texts are unchanged — they still read in place beside the argument, where they have always fitted comfortably.

Destructive actions are easier to read. Buttons like "Create counterargument", "Delete Claim", "Clear review", "Make private" and the account deactivate/delete controls are drawn as an outline rather than a filled block, so their clay colour sat directly on the page — just under the contrast threshold for comfortable reading, in both light and dark themes. They now use a slightly deeper shade of the same clay, which clears it. The same correction reaches the smaller red cues around an argument: the "Contested" tag, the "NOT" markers on claims and operators, the counter badge on responses, and the counter edge in the graph view.

The same pass continues to the citron green, which had the same problem more severely in the light theme: the outline marking which claim, premise, formula or pipeline step you have selected, the highlight when a card is hovered or focused, the curated-argument seal, the consequent edge in the graph view, and the emphasised words in the argument builder's intro. All are now drawn in a deeper citron in light mode. Dark mode is unchanged throughout — it already had enough contrast.
