A filter plug-in gets 50 M instructions and a minute for each run. Filters that order a plotter's paths, pack shapes or run a simulation need minutes, and the app shouldn't freeze while they compute. A filter's manifest may now ask for "budget": "heavy" (Budget): each run gets HEAVY_FUEL (1 G instructions) and HEAVY_WALL_TIME_MS (300 s). Only a filter may ask. plugin.install refuses such a filter without allowHeavy: true, and plugin.inspect returns the entry a module would have without installing it. Install Plug-in… and File › Open ask the user and install on OK; the plug-in store keeps the answer, and folder loads skip heavy filters with a note, since they ask nobody. The app runs a heavy filter on a thread of its own (plugin_runs), not in Background Save's queue, with the status bar and a progress window (Cancel, Continue in Background) that it shares with Background Export (export_progress::window). FilterRun splits plugin.run: prepared on the session, run on any thread, its output handed in, and the next plugin.run with the same params applies that output instead of running the plug-in again, so the edit stays one guarded, journaled command. A result whose document or plug-in changed meanwhile is dropped, and the status bar says to run it again. A cancelled plug-in run is now EngineError::Cancelled. What a filter keeps with the document (#3720) goes with the run: it is given _context.documentData when the run is prepared, and the documentData of its output is applied with its objects, in the same undo step, when the run is handed in (FilterRun::finish). Tests: plugins/tests/abi.rs (100 M loop steps out of a light budget, within a heavy one; folders skip heavy filters), manifest.rs, engine tests_plugins.rs (consent, inspect, the store, hand-in, a handed-in run's document data, cancel) and ui-egui tests_plugin_runs.rs (installing asks, no Preview, a background run as one undo step, a stale result kept out, the progress window). CRAFT_UI_HEAVY_FILTER_WASM=<folder> writes a test filter to try in the app. Its strings and messages have rows in each complete catalog (COMPLETE_MESSAGES).
