Research direction

Start at the Editor.add_member() entry point and inspect its allowed member-kind handling, then compare it with the load_from_content path for a perform action usage. Add coverage for kind="perform action" so editor.apply() accepts the construct consistently with SysML text loading.

Written by the indexing model from the issue text.

Description

Summary

Editor.add_member() has no kind for a perform-action usage. apply() raises IllegalMemberKindError for kind="perform action", even though the equivalent construct loads fine as SysML text.

Version: OpenSysML v0.9.0.

Observed

editor = model.edit()
editor.add_member(owner="P::H", kind="perform action", name="heat", ...)
editor.apply()
# IllegalMemberKindError: kind "perform action" is not legal in SysML source

perform action heat : ToastBread; inside a part def loads without issue when supplied as SysML text via load_from_content.

Reference

SysML v2.0 (formal/2026-03-02), 7.17.6 Perform Action Usages — the construct that records which logical component is responsible for performing a given action.

Request

Add perform action to the Editor.add_member() allowlist, alongside the existing coverage requests for allocate (#599), flow, and state usages — this repo hits all of them in the same authoring pattern (a logical component performing a function).
