Implementation plan

Design and review

Read docs 06/14/16/17/18/19 and constitution; apply requested design skills and karpathy-guidelines. Existing system sans and semantic canvas/view/text/border/accent roles remain; Signal dark examples canvas #090909, view #111113. Branch at weight 600, path 0.9em secondary currentColor at 0.78 with high-contrast full foreground. Task label wraps to two lines; full-foreground state sits beneath it, aligned with text rather than icon. Keep existing quiet sections, flat actions and PR/diff semantics. No extra section headings, animation or decorative panels.

Baseline Details has branch/path at the same size/weight and combines Task name · state in one middle-ellipsized label. T3 Code ThreadDetailsCard/ThreadDetailsPanel at 50647de0143e68fde051eb1a0ccf4fe63f9947b2 supplies compact contextual-card hierarchy; translate it to existing native rows. Grok 4.7 High completed an independent read-only audit. Do not move the centered shell identity. Do not mistake pane fixture IDs for production defects.

Technical sequence

Existing details.rs owns widgets and fill. Add semantic CSS classes to existing branch/path labels, a task-state label under its row and a full title tooltip; keep decision data and IPC untouched. Native GTK logical alignment handles the new metadata line. An AdwClamp limits the card to 300px so long branch/path/title natural sizes cannot expand the popover beyond a 360px window. Extend existing Details test first for separate state/wrapping and stress long data at narrow/default/enlarged/DejaVu/RTL. Reproduce red, implement, capture/inspect actual renders and preserve exact clipboard/navigation checks. Evaluate Grok audit, obtain independent two-axis final review, retain selected evidence and Before/After/Why table. Freeze all source before full and delivery gate. Publish/link, inspect latest refs/reviews/CI and merge when authorized gates pass.

Constitution and technical context

Rust 1.94 development/minimum 1.92, GTK4/libadwaita. GUI-only presentation with existing model and asynchronous generation guard. No new load-bearing choice, domain data or dependency. Native allocation requires GTK display tests; manual screen-reader/IME certification is not claimed.
