- Around line 94-100: Update the output handling in the `s.edit` closure to skip
`objects::apply_output` only when `inputs` and `out.objects` are both empty and
`out.document_data` is present, returning an empty ID list so
`d.set_plugin_data` can run. Preserve `objects::apply_output` for all other
cases, including empty output with nonempty inputs.

Commit data-only filter output when no objects are selected.
When plugin.run receives {"objects":[],"documentData":...} with no input objects, objects::apply_output returns the objects to change are no longer in the document before d.set_plugin_data runs. The filter cannot save document-level data in this reachable no-selection workflow. Skip object application only when both the input and output object lists are empty and documentData is present. Preserve the existing contract that an empty output deletes nonempty inputs.

A filter plug-in had nowhere to keep settings that belong to the whole document rather than to one object, such as the pens a plotter holds or a machine profile: it could only ask for them again on every run. - A filter's output may hold documentData: any JSON of at most 1 MiB (objects::MAX_DOCUMENT_DATA) that replaces what the plug-in keeps with the document, null removing it, in the same undo step as its objects (objects::decode_output). Too much refuses the output and the document stays as it was. - A filter gets it back in _context.documentData (null until it keeps something). A filter reads and writes only its own. - It is the document's foreign data, Document::unknown["pluginData"] by plug-in id (vectorcraft_doc::plugin_data), where the perspective grid and the brushes keep theirs. So the native file needs no section of its own for it, and hosts from before keep it when they save. An exporter is given the whole document, so it can read every plug-in's. Nothing else lists it, as the reference app's Document Info lists no plug-in data. A live effect isn't given it: its geometry is worked out from the object alone wherever it is drawn. Tests: plugin_data.rs (each plug-in its own entry, forgetting what isn't kept copies nothing, a damaged value holds nothing), objects/tests.rs (kept, forgotten, refused over the limit), tests_plugins.rs (one undo step with the objects, read back, not given to another filter, kept by the native file among its foreign data, refused over the limit with the document unchanged, null removes it) and tests/plugin_export.rs (an exporter finds another plug-in's). The size error has its row in each complete catalog (COMPLETE_MESSAGES).

… (G17) 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.

What and why
A plug-in had nowhere to keep settings that belong to the whole document rather than to one object, such as the pens a plotter holds or a machine profile (G17). It could only ask for them again on every run.
documentData: any JSON of at most 1 MiB, which replaces what the plug-in keeps with the document (nullremoves it), in the same undo step as its objects. Too much is refused, and the document stays as it was._context.documentData(nulluntil it keeps something). A filter reads and writes only its own.Document::unknown["pluginData"], by plug-in id, where the perspective grid and the brushes already keep theirs. The document model and the native format don't change, and hosts from before this keep it when they save. An exporter is given the whole document, so it can read every plug-in's data, not only its own. Nothing in the UI lists it, as the reference app's Document Info lists no plug-in data.A live effect isn't given it: its geometry is worked out from the object alone wherever it's drawn.
This follows the reference app, whose plug-ins reach a document dictionary through the SDK that is saved in the
.aifile and isn't listed in Document Info (forum example).It replaces #3176, whose first version added a
plugin_datasection to the native file and a Plug-in Data category to Document Info, both product decisions; this version needs neither. One commit onmain.How it was tested
Tests.
crates/doc/src/plugin_data.rs: each plug-in has its own entry, forgetting what isn't kept copies nothing, and a damaged value holds nothing.crates/plugins/src/objects/tests.rs:documentDatais kept, forgotten (null) or, over 1 MiB, refused.crates/engine/src/tests_plugins.rs: a filter writes its data in one undo step with its objects and reads it back, another filter isn't given it, the native file keeps it among the document's foreign data, more than 1 MiB is refused with the document unchanged, andnullremoves it.crates/engine/tests/plugin_export.rs: an exporter finds another plug-in's data in the document it is given.No UI changes, so no pictures.
Docs:
docs/plugins.md(context, output and where the data lives),docs/gaps.mdG17 anddocs/target-app-parity.md(evidence; scores and hours unchanged). The new error message has a row in every complete catalog.Checklist
