## What changed
- Add tab switching with keyboard navigation and a `.viz-carousel` variant picker with previous/next controls and screen reader announcements.
- Support touch tooltip toggling and tooltip triggers inside shadow roots.
- Refresh typography, tables, buttons, and form controls; add widget and progress styles and larger touch targets.
## Testing
Add a viewer snapshot test covering embedded tab and carousel scripts, generated control markup, and selected CSS rules.

## Why
Syntax theme colors can have insufficient contrast against the terminal background or the shaded proposed-plan surface.
## What changed
- Adapt themed Markdown foreground colors to the terminal background while preserving inline code colors from the syntax theme.
- Adjust proposed-plan foreground colors after applying the plan background, including retained styles used for reflow. Apply the same styling to streamed and completed plans.
## Testing
Expand snapshots across syntax themes and light and dark backgrounds, and cover proposed-plan tables and streamed plans with wrapped hyperlinks. Update streaming assertions to expect contrast-adjusted blockquote colors.

## What changed
Use the active syntax theme's markup foregrounds for headings, emphasis, strong text, list markers, links, and blockquotes. Preserve existing bold, italic, and underline modifiers, and retain previous styles when a scope provides no foreground.
## Testing
Update rendering snapshots and streaming blockquote assertions for themed colors. Exercise existing fallback expectations with an empty syntax theme.

## Why
Transcript selections were copied as plain text, losing the formatting of rendered Markdown when pasted.
## What changed
- Retain semantic Markdown annotations through rendering, wrapping, and streaming, then serialize selected text with balanced markup.
- Preserve inline formatting, web links, headings, lists, blockquotes, and hard breaks in Markdown clipboard payloads.
- Keep code-only and other literal-only selections as plain text. In mixed selections, escape user prose and fence code, tables, and tool output to preserve their literal content.
## Testing
Add unit tests and Markdown/HTML snapshots covering partial selections, nested containers, escaping, links, resize stability, and streaming boundaries.

## Why
Theme colors and dimmed text can lose contrast against terminal and shaded backgrounds. Pickers also need to keep controls and the selected result visible when space is limited.
## What changed
- Add shared blue accents and contrast-aware foregrounds that account for painted backgrounds and terminal color depth, with terminal-default fallbacks for limited palettes.
- Apply readable colors to footer text, status lines, prompt attachment labels, and diff content. Remove dimming from syntax-highlighted diff text so it does not undo contrast correction.
- Use compact shortcut labels such as `ctrl+c`, emphasize complete key combinations, and separate composer footer actions with ` · `.
- Add an opt-in picker presentation with full-width selection, filled tabs, separate overflow indicators, and navigation based on visible rows. Enable it for `/keymap`, reserving result space to keep controls stable across filtering and tab changes.
## Testing
Add regression tests and snapshots for contrast after palette conversion, shaded diff backgrounds, shortcut typography, picker resizing and pagination, Unicode tab truncation, and stable `/keymap` geometry.

## Why
Unterminated prose stayed hidden until a newline arrived or the stream completed, leaving long single-line responses invisible while they streamed.
## What changed
- Show live prose previews for agent messages and proposed plans, requesting redraws when the preview changes.
- Keep previews out of the scrollback queue and render the full source on newline or completion without duplicating text.
- Bound previews to the most recent 8 KiB at a Unicode character boundary, with an ellipsis for omitted text, and reflow them when the width changes.
- Preserve holdback for incomplete table and code structures, retaining the last safe prose preview when a pipe arrives.
## Testing
Add controller tests and TUI snapshots covering visibility before completion, resize reflow, finalization without duplication, long Unicode previews, table and code holdback, and inline visualization context.

## Why
Inline visualization viewer documents must remain outside locations that a
sandboxed session can modify before they are opened in a browser.
## What changed
- Materialize viewer documents in a dedicated cache under `CODEX_HOME`, keyed
by the source and artifact thread IDs, instead of alongside visualization
artifacts.
- Create visualization links only when the active filesystem policy cannot
write to the viewer cache. This also disables links for full-disk-write
sessions and applies the policy consistently when loading transcript history.
- Reject viewer cache paths containing symbolic links and track materialized
documents in memory so unchanged viewers are reused without trusting existing
file contents.
## Testing
- Verify that rendering an unchanged visualization reuses the existing viewer
file, while an updated fragment refreshes it.

## What changed
- Recognize structured `visualize` content references alongside the existing inline visualization directive in cached, streaming, and finalized TUI rendering.
- Resolve absolute visualization paths only when they belong to the active thread directory, and show the existing unavailable fallback for incomplete, invalid, or out-of-scope references.
- Let embedded visualizations inherit host color, typography, and radius tokens while retaining standalone defaults and legacy aliases. Keep Lucide icons at a stable size when model-authored chart styles are present.
## Testing
- Cover content-reference fallback, replay, render-cache bypass, and canonical streaming behavior.
GitOrigin-RevId: 887d13647df11c23d519e64d0958fdc41ef3f472
## What changed
- Upgrade `ratatui`, `ratatui-macros`, `crossterm`, and `ansi-to-tui`, and adapt the TUI to their updated rendering, backend, color-conversion, and cell APIs.
- Use Ratatui's cell-width and continuation-cell metadata when mapping OSC 8 hyperlinks so links remain aligned across wrapped wide glyphs and halfwidth characters with dakuten.
- Preserve explicit hyperlinks in the sign-in success screen and empty MCP state without embedding escape sequences in the text passed to Ratatui.
## Testing
- Add regression coverage for hyperlink placement across wide glyphs and halfwidth dakuten, hyperlink preservation in onboarding and MCP output, and display-width handling.

## Why
The transcript overlay cached every committed cell's height. Cells whose content changes after insertion, such as refreshed status output or newly available visualizations, could outgrow that cached height and be clipped.
## What changed
- Let history cells declare whether their transcript height is stable, and remeasure dynamic cells on later overlay renders.
- Preserve cached heights for stable cells when appending a committed cell instead of rebuilding all renderables.
## Testing
- Cover status output growing after a rate-limit refresh.
- Cover a visualization link replacing its unavailable placeholder.
- Verify that appending a cell preserves cached measurements for stable cells.

## Why
Assistant-authored inline visualizations need a terminal fallback that lets users open generated artifacts in a browser.
## What changed
- Recognize `::codex-inline-vis{file="..."}` directives in assistant Markdown and replace them with browser links during streaming, finalized history rendering, and local transcript previews.
- Materialize visualization fragments in sandboxed viewer documents with a content security policy, while restricting artifacts to HTML files within the thread's visualization directory and limiting their size.
- Show an explicit unavailable message for invalid or missing artifacts, hide incomplete streaming directives, and preserve directive text in code blocks and user Markdown.
- Add a trusted file-link path for generated viewers without enabling arbitrary `file:` links in Markdown.
## Testing
Add coverage for directive rewriting, streaming and replay, artifact validation, sandboxed viewer generation, trusted terminal hyperlinks, and literal preservation.
