Showing Cowork and GraphRAG always, greyed, instead of letting them appear and
vanish, moved the gate from "the row is absent" to "the row is disabled". That
guards the rail — Qt will not select a disabled row — but it guards only the
rail, and _goto is also reached from a RECENTS click and from startup restore.
Called with a gated sub-tab it opened the page while the workspace's own tab
strip still had it hidden.
_goto now asks WorkspaceTab.subtab_available() — the same isTabVisible state
that greys the row — and shows "Chọn project trước" in the status bar instead
of navigating. One gate, one place, whatever triggered the jump.
check_project_gate runs against an EMPTY home, because with any project on disk
the gate is open and the test proves nothing. It asserts the gated rows are
disabled and say why, that clicking them does nothing, that _goto refuses them,
and that + new chat and the project picker are off. Dropping the _goto guard
fails it with "_goto mo duoc 'Cowork' trong khi cong dang dong".
17/17 checkers pass.

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.
