Disconnect a Herdr session from the Sessions sheet without stopping the app - #236
Disconnecting a Herdr session from its row in the Sessions sheet no longer stops the app.
Why
The sheet's Disconnect swipe button was a destructive action. A list takes the row of a destructive swipe action out by itself and expects that row to be the only one to go. A Herdr session that lists its workspaces leaves with those rows as well (each workspace and New Workspace), so the list's count was wrong and it stopped the app with Invalid update: invalid number of items in section 0. A session shown as one row (tmux, or a Herdr session folded away) was not affected.
Disconnect is not destructive either: the session keeps running on its server and is offered again under Recent.
How
The button keeps its red tint and is an ordinary action, as Home's Disconnect already is. It looks the same.
Validation
New live UI test testLiveHerdrDisconnectFromSessionsWithWorkspacesShownWhenConfigured: against an isolated Herdr 0.9.5 session it stops with "dev.remux.app crashed" without the change and passes with it (two runs), on an iOS 27.0 simulator.
With a throwaway test that is not in this PR: two Herdr sessions open, each disconnected in turn from the sheet with its workspaces listed; the app stays up, the other session stays open after the first, and Home shows after the second.
The swiped row was captured before and after the change and the two pictures are identical.
First seen on an iPhone 14 Pro Max on iOS 27.3, whose crash report shows the same list update failing.
Summary by CodeRabbit
Bug Fixes
The active session’s swipe-to-disconnect action keeps its red styling and continues to disconnect the selected session. It is no longer presented as a destructive action, while remaining available from the Sessions sheet. This keeps the action’s visual cue and behavior consistent without using the destructive-action treatment.
…he app
The sheet's Disconnect swipe button was a destructive action, which has the list take the swiped row out by itself and expect that one row to be the only one to go. A Herdr session that lists its workspaces leaves with their rows too, so the list's count was wrong and it stopped the app. The button stays red and is no longer a destructive action, as Home's Disconnect is; the session keeps running on its server either way.
The active-session “Disconnect” swipe action is now a regular button with a red tint. A live Herdr UI test covers disconnecting while workspace rows are shown.

Summary
Disconnect action and UI coverage RemuxApp/Sources/App/SessionSwitcherView.swift, RemuxAppUITests/RemuxAppUITests.swift
The swipe action retains its warning haptic and disconnect callback but is no longer destructive. The UI test verifies the sheet closes, Home appears, the app stays in the foreground, and the session is no longer active.

Merge Risk: Minimal · up to 28b53
Disconnecting a session from the Sessions sheet should no longer stop the app when workspace rows are shown. No actionable merge-blocking risk remains.

Add coverage for disconnecting with another session open.
This test closes the Sessions sheet when it disconnects the only session. When another session remains, RemuxRootModel.disconnectActiveSession selects it and the sheet stays open while its list updates. Add a two-session regression case that checks the list and the remaining session after Disconnect.

Add a two-session regression case alongside the existing disconnect test: disconnect the active session, verify the Sessions sheet remains open and its list updates to show only the remaining session, and verify that session is selected. Preserve the existing coverage for disconnecting the last session.
