improvise-9c8c. The two files this unit owns, written before any comment is capped so nothing is capped without somewhere to land. context/code/tui.md carries the grid widget's module doc whole (it is the best-written statement of the no-&Model/no-&View rule in the repo, better than the repo map's own), the two semantic-to-terminal colour mappings and why mode_style is NOT that shape (improvise-zx8t), the wizard's set_bottom_line and bytes-vs-cells arguments, and the per-frame cache building that is the temporary half of improvise-35e. context/test-evidence/tui.md carries the injected-fault records, keyed by test name per design-principles §7 — including THE_MEMBERSHIP_CORRECT_SPANS, whose assert_ne! is a live tripwire that starts failing the day improvise-gd83 is fixed.
