The gallery root scope and the Images listing cursor were keyed with a per-process random key, so every ComfyUI restart made an open tab's scopes answer 409 source-changed (blank Tag image preview, a Generate that did nothing) and its cursors fail Load more. - utils/workspace_keys.py: one random secret in workspace-scope.key beside the database (owner-only, never config.json or the database), two derived keys; per-process fallback with a warning. Move library copies it. - Cursor v2 binds the listing scope in its MAC instead of sending an unkeyed hash of the root paths; an unverifiable cursor answers 400 cursor-stale and Images offers Refresh instead of a dead Retry. - POST /prompt_manager/images/rescope maps a stale target to its current root only when the held scope was issued for it. - Images finds a renumbered file again from the inspector, the viewer and the Tag image dialog (the dialog stays open, draft kept); nothing else is kept by an old root_index:path key. - Tag image dialog: a state that blocks Save shows its reason above the actions with Refresh, disabled actions look disabled, and an empty preview says "Preview unavailable" (D147).

"""POST /prompt_manager/images/rescope: a stale target's current identity (#430).
|
|
|
|
A page that holds ``{root_index, root_scope, path}`` after the sources were
|
|
renumbered asks where that file is now. The server maps the target only when
|
|
its scope was issued, at its old index, for one of the current roots, so the
|
|
answer names nothing the page could not already address; a removed or
|
|
replaced root, a foreign scope or a changed key stay refused.
