The Session row's action strip stops click propagation itself, so a
`sidebar.workspaces.session.row.action` entry that renders a plain button no
longer opens the row as a side effect; the shipped buttons drop their own
handling. `Menu` decides submenu exclusivity on the list's own bubbles, by
DOM: reaching a top-level row that is not a submenu parent, by pointer or by
focus, closes the open card for data rows and component rows alike, which
the per-row handlers only did for data rows. A group start on the list's
first row draws no hairline.
The first live-fixture e2e case registers the scaffold's cleanup right after
launch, as the file's other cases do. The three pin scenarios the browser
spec lost when the order write moved into `UiWorkspace.pinSession` — newer
saved orders during a pending pin, a Workspace disappearing during one, and
members whose summaries are temporarily missing — return as service cases.
The fixture plugin's rows join `sidebar.workspaces.session.menu.item` after
the shipped rows, the first one opening the plugin group with
`separatorBefore`, and dismiss the menu through `useMenuOpenState`.
master's session row menu now leads with Pin session and SessionNode
carries pinned/archived, so the slot-action specs and the Web golden take
the row as it is after the rebase.
The Plugins page declares three slots as children of its main entry:
`plugins.item` lists an official plugin's page in the Official group,
`plugins.bundle.config` renders a bundle's own form on its page, and
`plugins.row.config` gives a row a configure control opening the row's
page. Every entry renders in the `summary` and `page` views the page
passes as owner props; the page draws the title, icon, and crumb and
projects the ledgers beside its store, naming no configurable plugin.
`ui-settings-plugins` registers its four host-plane pages into
`plugins.item` while the Host serves their namespaces and withdraws them
when it stops; the forms keep edits until a save and drop them on leaving
the page, so the discard control and the unsaved marker are gone. The
Settings section becomes the Built-in plugins shell around the inventory
tab, and `settings.plugin.item` is retired.
The Official group opens with the optional bundles the installation
ships, tagged Beta where the feature is one and without an official tag,
followed by the configuration pages. Auto review leaves the optional
bundles and the CLI's dependencies; the install guide names it as its
example spec. The version tag is a capsule like the other tags.
The `plugin-config` web lane drives the pages through the real wire and
opens a community fixture's row page after switching its bundle on; the
settings lanes re-record the renamed navigation entry.
