Picking a session with Open Session or dropping one on the page in the
browser replaced the document as soon as its bytes were read, without the
Save Changes question the native Open goes through, so unsaved edits and
their undo history were lost. The bytes now wait behind that question,
asked when the read finishes: Don't Save opens them, Save saves first and
then opens them, Cancel drops them and leaves the document alone.
Close Session, New, Open, Revert, Quit, the window's close button,
dropping a session file on the window and opening one from the Workspace
window all replaced or closed the session without asking, so unsaved
edits were lost (#136). They now ask first: Save, Don't Save or Cancel.
Save on a session that has never been saved goes through Save As, then
carries on. Revert asks for confirmation instead, and Revert to Saved is
unavailable until the session has a file. A take being recorded is
stopped first, so it counts as a change. The web build has nowhere to
save, so it offers only Don't Save and Cancel. Calls from the control
channel, MCP and the CLI never ask.
Selecting, locating, zooming and scrolling no longer mark the session
modified, so the question only comes after real edits. Undoing back to
the saved state makes the session clean again. The engine compares the
document with the one last opened or saved, ignoring the selection, the
playhead and the zoom, once per revision.
