The selected row carries selection-background-color, so a checkmark repeats
what the colour says — and in a combo as wide as "VN" it repeated it on top of
the letters. A combo's default delegate paints menu-style, which is where the
glyph comes from; a plain QStyledItemDelegate paints item-view style, which has
none. widen_popup does both jobs now, so it is tidy_popup.
check_combo_popup additionally requires the delegate to be the plain one and the
stylesheet to still tint the current row — removing the delegate line fails it.
21/21 checkers pass.

Settings sat closer to its icon than Dashboard and Giám sát do. Those are tree
rows, laid out by the style; Settings was a QPushButton, whose icon-to-label gap
is also the style's — and the two do not agree. The Windows fix for this was a
19px icon box that nudged the label 1px, which is exactly the kind of tuning
that only holds on the machine it was measured on: on macOS the gap is tighter
again. The row now lays itself out, 4px in and 6px between, the same two numbers
the tree uses. Icon x=4 and label x=26 against the rows' 4 and 26 — equal, not
close.
The language drop-list showed a tick over its own text. macOS marks the current
row with a checkmark and Windows does not, and the popup inherits the combo's
width — which for "EN/JP/VN" is about 50px, all of it needed by the letters.
widen_popup() measures the longest item plus the platform's indicator and sets
the view's minimum, so the tick has its own room wherever it is drawn.
That check found two more: the project picker (191px of text in a 138px popup)
and the provider list (221px in 138px) were both truncating names here, tick or
no tick.
Neither could be reproduced on this machine, so the checks assert the property
that made the bug possible — spacing we control rather than the style's, and a
popup measured against text + indicator — not the platform.
21/21 checkers pass. check_nav segfaults in Qt teardown after printing its
verdict, twice in one suite run and 0 times in 8 standalone runs; pre-existing.

Reading the page's Overview line by line against the app turned up more than
layout:
* Tab strip: "Sự kiện bảo mật / Lịch sử gọi MCP / Nhật ký hành động /
Trạng thái Agent" → "Bảo mật / MCP / Hành động / Agent", as drawn. The long
names are also what pushed "Icon" off a 1024px window behind scroll arrows;
all eight now fit.
* Headings: "SỬ DỤNG TOKEN & CHI PHÍ" → "TOKEN & CHI PHÍ", "SỬ DỤNG TÀI
NGUYÊN" → "TÀI NGUYÊN", "CHI TIẾT SANDBOX" → "SANDBOX & QUYỀN",
"HOẠT ĐỘNG GẦN ĐÂY" → "NHẬT KÝ GẦN ĐÂY".
* Tiles put the number FIRST and its name under it, which is how the page
draws them; "Tổng chi phí" → "Chi phí" and Budget → "Ngân sách" in
Vietnamese. Applies to the Dashboard's cards too, which share the widget.
* Resources showed I/O and network RATES; the drawing shows capacity —
memory as used/total (138 MB/15 GB) and the workspace drive's free space
(15 GB trống). The rates are still measured and kept.
* "SANDBOX & QUYỀN" rendered as "SANDBOX _QUYỀN": a group-box title treats
"&" as a mnemonic. Same bug as the usage title, now fixed in both.

Two things differ between machines and only one of them is width: a 4K panel
has more pixels, while a 125%/150% display has the same logical pixels holding
LESS, because every label and margin is taller. Breakpoints written as raw
pixels only hold on the machine they were tuned on.
* ui_scale() derives a factor from font height (1.0 at the 15px line the
layouts were measured against) and every narrow-guard threshold is
multiplied by it, so panes fold when the content is cramped rather than
when a number is crossed.
* The window takes a share of the available screen (80% × 85%) with the old
1180×760 as the floor, instead of opening at that size on any monitor.
* Moving the window to another screen re-pins the assistant and re-decides
the fold, since the new screen's work area and scaling may differ.
Found by tools/check_multi_screen.py, which walks 5 window sizes × 3 font
scales:
* At 150%, Schedule was clipped on 1280 and 1366 screens and the window's
own minimum grew to 1459px — wider than a 1280 laptop, so the app could
not fit at all. The cause was not the lanes: the one-line lane-count
summary in the header reported a sizeHint wide enough to set the minimum
width of the entire window. It now yields first (its text stays in the
tooltip); the window minimum drops 1459 → 752 and holds there at every
scale.
Also: these checkers exited 0xC0000409 from a Qt teardown crash AFTER printing
their verdict. check_probes_bite decides whether a probe caught its mutation by
reading exit codes, so a crash would have counted as "caught" — the round could
have passed while proving nothing. They now flush and os._exit with the real
verdict, and round 5 still catches all six mutations.

check_design_parity read its checklist from build_audit_page.ANALYSIS. Eight
sections of the audit page are hand-written, and for those the generator's
text is NOT what the page says — so Settings and the Task editor were reported
as matching a design they had never been compared against. The Task editor was
in fact built backwards.
* The checker now reads the "Thay đổi" bullets straight out of
docs/ui-audit.html, and reports how many bullets on the page still have no
probe (57 on the page, 32 probed) instead of implying full coverage.
* Task editor: reverted from three step tabs to a left list + right panel,
five rows matching the five real group boxes — which is what the page asks
for, in as many words ("thay vì chia tab"), for consistency with Settings.
* Settings now switches panels rather than scrolling, so both dialogs are
navigated identically and neither is a long scroll any more.
* Settings field presentation, as the page's second bullet asks: the six
checkboxes became switches, and Language/Theme became segmented controls.
ToggleSwitch subclasses QCheckBox and SegmentedControl exposes the slice
of the QComboBox API this dialog uses, so no save/load path changed —
verified by round-tripping language/theme/tray through _save().
All 22 task-editor fields and 14 settings fields verified present after the
move; 7 suites green.

Implements the redesign from docs/ui-audit.html. Rearrangement only — no
feature was removed; every control that moved kept its handler, and the
gates that used to hide things now grey them out instead.
Navigation
* The rail is one flat list: the five Workspace sub-views sit at the top
level instead of behind an accordion, with Dashboard/Monitoring pinned
at the foot and Settings below them.
* Cowork and GraphRAG stay listed and greyed while no project is
selected, rather than vanishing and resizing the menu under the user.
* Monitoring keeps its eight sub-views in its own tab strip (unhidden)
instead of doubling the rail's length.
* _goto now moves the highlight itself, fixing a long-standing bug where
programmatic navigation left the rail pointing at the previous screen.
* Rail header gained the project picker and "New chat"; RECENTS lists the
active project's threads. Both are second views of existing state — the
Cowork toolbar button and the full History panel are untouched.
* Provider / language / theme moved from the top bar to an account row at
the foot of the rail (same widgets, same signals).
Screens
* Co4E: the flow tab strip is gone (per the design); Flow Status became a
toolbar toggle with its own way back, and the three icon-only tabs became
four labelled, foldable sections in one column. One flow open at a time
is the one capability this costs; background runs are unaffected.
* Dashboard: header split into two rows; cost promoted to a hero card.
* Monitoring Overview: one scrolling column of titled sections; the model
price table got its own full-width section instead of sharing a row with
the CPU meters.
* Settings and Task editor gained a section index down the left.
* Help dock: 84x64 launcher + chevron became one 26px dot that expands to
a labelled pill on hover; "hide to the edge" moved into the panel's menu.
Layout
* The window's minimum width dropped from 1453px to 768px. The main cause
was a QTabWidget taking its minimum from the widest page even when that
page is hidden, so Co4E was forcing Project and Cowork wide.
* Secondary panes fold themselves on a narrow window and restore when it
grows, never overriding a fold the user made.
* The long dialogs no longer scroll sideways at any font size.
Verification: tools/check_*.py build a real MainWindow offscreen against a
copy of ~/.cowork_local with the schedulers no-oped. check_design_parity.py
reads its checklist straight from the audit page's own proposals.

The Gitea repo was initialised from an earlier snapshot, so main and the
machine this runs on had drifted apart in 153 files before any UI work
started. This commit brings the branch up to the local tree as it stood
on 2026-08-15 21:31 (from cowork_local.7z), so the redesign that follows
shows up as its own reviewable diff instead of being mixed in with the
pre-existing divergence.
