From a7418f91f9da952062cb4100c1eaafc390d2eedc Mon Sep 17 00:00:00 2001 From: AI Agent Bot Date: Sat, 21 Feb 2026 07:04:00 -0600 Subject: [PATCH 1/6] feat: comprehensive improvements across all 10 phases (#27) Full-codebase improvement spanning architecture, backends, testing, UI, browser, terminal, window manager, performance, docs, and accessibility. 70 files changed, +5056/-333 lines, 489 new tests (2428 -> 2917). Phase 1 - Architecture: GradientStyle enum, TextMetrics struct, pub(crate) browser modules, oasis-core prelude, pinned git deps. Phase 2 - Backend parity: SDL network/audio streaming, UE5 graceful audio stubs with callbacks, PSP shape rendering (rounded rect, circle, line). Phase 3 - Test coverage: 489 new tests across oasis-app (68), oasis-ui (140), oasis-wm (89), oasis-vfs (52), oasis-net (27), oasis-core plugin (32), plus property-based tests. Phase 4 - UI completeness: Tooltip widget, keyboard navigation system (focus ring, Tab/Shift-Tab), enhanced modal dialogs, visual glitch fixes. Phase 5 - Browser CSS3: Incremental layout with dirty flags and edge cache, HTML nesting depth guard (256), CSS value proptest. Phase 6 - Terminal: MAX_OUTPUT_LINES 2000, stderr separation (2>/2>>/ 2>&1), shell functions, help --category filter. Phase 7 - WM polish: WindowId(Rc) for cheap cloning, screen bounds clamping, edge snapping (8px), titlebar gradients, modal z-order (normal < always_on_top < modal). Phase 8 - Performance: Incremental browser layout, PSP stack buffer safety, benchmarks in CI pipeline. Phase 9 - Documentation: Troubleshooting guide, plugin dev guide, command dev guide, 16 Cargo.toml doc URLs, feature flag docs. Phase 10 - Accessibility: Reduced-motion mode, font scaling (0.5x-3.0x), colorblind theme (deuteranopia-safe), spinner widget.

This caused the progress bar to stretch over the label's allocated space. Now the Bar arm draws the label text and offsets the bar track accordingly.
