+# Track A verification — 2026-11-05
+
+Branch: `v2-ui`. Base: `92e278b`.
+
+## Implemented
+
+- B1: 48 px activity bar, scrollable sidebar views, editor-first splitters, bottom panel; Ctrl+B/Ctrl+J and QSettings size/visibility persistence.
+- B2: escaped literal ampersands in docks, debugger tabs, and dynamically named editor tabs.
+- Command centre, command palette, incremental Quick Open, workspace text search, Git view, and File/Edit/Selection/View/Go/Run/Terminal/Help menus.
+- Existing menu actions preserved as the same QAction objects; original action names captured in `tests/fixtures/v1_actions.json` and checked after relocation.
+- Medhā Dark/Light with shared QSS and central color tokens, readable activity icons, grey close buttons, editor gutter and clickable minimap. Windows PyInstaller spec includes the QSS resource.
+- Welcome page with new C file, open folder/file, current Recent list, Turbo examples, and DSA entry points.
+- Real local branch, document/language/encoding, compiler availability and build diagnostics; optional CPU/RAM sampling.
+- B4, B6, B7: prerequisite duplicate-loader, offline-test and lint cleanup in separate commits.
+- Newly documented B8/B9: orderly process shutdown and Save/Discard/Cancel protection for edited tabs/windows.
+
+## Checks by step
+
+All counts below are offline. The real registry test is explicitly skipped unless
+`MEDHA_NETWORK_TESTS=1`; local fake registry-server tests still run.
+
+| Step | Full pytest | UI smoke |
+|---|---|---|
+| Baseline | 85 passed, real-network test deselected | baseline screenshots |
+| B6 | 86 passed, 1 skipped | window opens |
+| B4/B7 | 87 passed, 1 skipped | 1 passed |
+| B2/B8 | 88 passed, 1 skipped | 2 passed |
+| Workbench/B1 | 91 passed, 1 skipped | 5 passed |
+| Navigation | 93 passed, 1 skipped | 7 passed |
+| Themes/minimap | 94 passed, 1 skipped | 8 passed |
+| Welcome/close guard | 96 passed, 1 skipped | 10 passed |
+| Status/actions | 98 passed, 1 skipped | 12 passed |
+| Final regression checks | **106 passed, 1 skipped** | **20 passed** |
+
+Pyflakes is clean after B7 and at every subsequent completed step.

+QT_QPA_PLATFORM=offscreen python -m pytest tests/test_ui_smoke.py -q

+
+UI tests check tool routing, both screen sizes/themes, actual text viewport width,
+keyboard toggles, settings restoration into a second window, palette action
+preservation, Quick Open, Search, Recent, minimap navigation, real status updates,
+unsaved-close cancellation and cancelled Save As. Requests are blocked during UI
+startup, and Qt callback exceptions are collected as failures.
+
+The all-action smoke test triggers every menu action from the legitimate Welcome
+(no active document) state. Dialogs are cancelled and external CMake build calls
+are stubbed. It verifies UI wiring and survival, not every compiler/debugger backend.
+Focused tests exercise document operations separately.
+
+## Review limits
+
+- Screenshots and tests ran on Linux/PySide6 6.12. Windows install/launch/uninstall and the full cross-platform release checklist are still required before release.
+- B3 (PTY/ConPTY) and B5 (remaining broad exception handlers) remain Track B work.
+- Original UI supported only dark; before-light images cannot be captured authentically. Both new themes have full after evidence in `screenshots/v2/`.
+- No Store submission, release version change, or merge is included.

+Captured from the real PySide6 window on Linux with `QT_QPA_PLATFORM=offscreen`.
+Images are native 1366×768 and 1920×1080 pixels, without rescaling.
+
+| State | 1366×768 | 1920×1080 |
+|---|---|---|

+
+The original application has no light-theme switch, so a genuine before-light
+capture is unavailable. No synthetic before-light image is supplied.
+`step-1` through `step-5` retain intermediate layout/navigation/theme/welcome/status evidence.
+
+The editor tab region increased from **127 → 1044 px** at 1366×768 and
+**301 → 1598 px** at 1920×1080. Automated assertions also check the actual text
+viewport (excluding the gutter and minimap) remains at least 60% of window width
+in both themes at both resolutions.
+
+The red terminal job-control warning is existing **B3**, assigned to Track B.
+It remains visible in these unedited screenshots; this PR does not implement a PTY.
+
+Reproduce from the repository root in an environment with the dependencies installed:
+
+```sh
+QT_QPA_PLATFORM=offscreen python tools/capture_v2.py --phase after
+QT_QPA_PLATFORM=offscreen python tools/capture_v2.py --phase after-welcome --welcome
+```
+
+The capture tool uses a temporary project and isolated settings, then shuts down
+its processes. It does not change the user's workspace or preferences.
