One unreadable tile used to block editing, saving and exporting every open document (spill::check_integrity was process-global). Add Tile/Surface/Document::scratch_health (free while no tile has failed) and Document::for_each_surface (ops' history walk now delegates to it). edit_with checks the document before and after, jobs the document they captured, import the result, save/export the document written; check_since is now generation-only so a failure or recovery during an operation refuses it once and a retry works. Caches check their own sources and purge once per new failure instead of every frame. Fault-injection tests use a duplicated handle (the Unix file has no name).
