- The real-browser collapse smoke tracked the old chrome: visible HARNESS
text (the wordmark svg is aria-hidden now), an 'Expand sidebar' label
(renamed 'Open sidebar'), a 300px settle (default is 280), and an
immediate focus assert (rail search defers focus past the slide). The
case now tracks the brand span, polls the deferred focus, and uses the
current labels and width.
- Tooltip treated hover and focus as one trigger: leaving with the mouse
dropped the bubble of a still-focused anchor (and vice versa). The two
triggers are tracked independently; the bubble hides only after both
clear. Spec pins both orders.
- The ui-sidebar README and the bilingual collapse note still described
the retired geometry morph; both now state the slide + crossfade
contract, the fixed-width (never-conceding) sidebar, and the rail's
whale-mark/tooltip chrome.
The collapse read as a hard cut: only the track width animated while the
panel content swapped instantly and the rail icons bore no relation to the
expanded layout. Now the four control rows persist across the transition —
collapse toggle, new session, new workspace, search, the same top-down
order as their expanded rows — and morph their geometry (row heights,
paddings, margins, capsule borders) on the deepsuite curve, so each rail
icon is its expanded control converging onto the 56px axis. Wide-only
content (brand, labels, input, session tree) cross-fades over 200ms, stays
mounted while the collapse animates, and unmounts at the 300ms settle,
still dropping the sessions subscription. The search query moves up to the
root and survives the round trip; rail search focuses the surviving input
after expand instead of remount-autofocus.
The collapsed rail becomes a 56px icon column (24px controls between 16px
paddings) carrying expand, new session, search, and new workspace — each
aligned with its expanded counterpart; rail search expands the sidebar and
focuses the search box. Collapse/expand now animates: the frame transitions
grid-template-columns (and the surviving handle its left) on the deepsuite
sider curve — --ds-ease-in-out over --ds-transition-duration-slow, supplied
by ui-theme's base sheet. Transitions pause during drags (data-dragging on
the frame, set for the whole gesture) and under prefers-reduced-motion.
A closed sidebar previously resolved to a zero-width grid track, clipping
the only toggle and the settings entry with no visible recovery; the closed
preference persisted across reloads, locking the sidebar shut.
- columns.ts maps the closed preference (width 0) to a fixed 60px
SIDEBAR_COLLAPSED rail through every step of the concession solve;
closed details still resolve to zero width.
- AppFrame derives data-sidebar-collapsed and the sidebar slot's collapsed
owner prop from the persisted preference instead of the resolved track
width, and drops the resize handle while collapsed.
- SidebarRoot reads the owner collapsed prop; the expanded-only body is a
separate component that unmounts while collapsed (dropping its sessions
subscription), leaving the expand toggle and Settings in the rail.
- The keyless web smoke gains the ui-sidebar bundle (six real bundles) and
pins the 60px rail collapse/expand round through the assembled client.
