A rollback reverts the local data with a rebase, which is not a commit,
so the parts of the workspace that follow commits missed it:
- Comment pins moved in the reverted action stayed where they were, on
screen and on the server, and pins on a board the rollback removed
kept pointing to it. They go back to the reverted position, and pins
on a removed board move to the page root.
- Focus mode stayed on with no shape left when the rollback removed the
focused ones, and the next shape drawn turned it on again. It ends
when its last shape goes, and the selection drops removed shapes.
- Component thumbnails kept the rejected look. The thumbnails of the
reverted mains are rendered and uploaded again, and an upload whose
shapes changed during the render is skipped.
- Under WASM, an open text editor reset to the reverted content but the
canvas kept the old layout. It is laid out again.
- A library sync whose save failed showed no update notice again once
the release undid it. The notice is checked again after that
rollback.
The notice of a rejected save always said the same thing. It did not
name the file when the user had moved to another one, gave no hint when
the page held data that was already invalid, and replaced the notice of
a backend repair still on screen, since the store holds one toast.
The backend flags a rejection whose first commit touches pages or
components that failed validation before it (:preexisting-damage). The
rejection notice names a file other than the open one, says when the
data was damaged before, and folds into a repair notice still on
screen; a later repair notice folds a rejection notice in the same way.
The notice says that the latest changes were undone, no longer that the
rest of the work is saved.
When a peer restores a version, the file reloads to it. Edits made on
the replaced version stayed queued: their save failed for good and
locked the workspace, and a rollback or a rebase replayed them on the
restored data.
Loading another version forgets the queued, buffered and saved commits
made on the old one. A save of such a commit, in flight or answered, is
dropped instead of failing or being rolled back, and one save carries
the edits of one version only.
The backend rejects a save after the call that made the changes has
returned, and the workspace then undoes them. A plugin, or the MCP
agent, went on working with shapes that were no longer there and never
learned why.
The rollback event now names the files that lost commits and the pages
and page shapes their changes touched, and plugins get it as the new
`contentrollback` event (`ContentRollback` type) through a subscription
to the store stream, so no rollback is dropped by debouncing.
The MCP plugin keeps the rollbacks it is told about and sends them with
its next task response, failed or not. The server collects them per tool
call and puts a warning first in that tool's response, naming what was
affected; the instructions tell the agent to read the pages again and
redo what is missing.
A rollback can remove or change shapes the UI still refers to.
- The selection drops shapes that are gone and the color picker that
edited them closes.
- The undo history is cut at the reverted action; it stays when no
entry holds a reverted change. Undo and redo commits carry real undo
changes and the history index they moved from, so a reverted Ctrl+Z
puts the change and the index back.
- An open path edition whose shape the rollback changed closes without
saving the editor's stale copy. The v2 text editor loads the reverted
text again; the WASM editor already showed it.
- The Alt measurements look the hovered shape up in the current data.
- Plugin setters, resize() and rotate() on a removed shape throw
"Shape not found", whatever the plugin's throwValidationErrors flag.
