Summary

Add plotium_apply, which takes plotium_plan inputs and plans and commits one reversible edit in a single call, returning the plotium_execute result. It accepts property writes, figure edits without deletions, plot creation, curve append, binding and expansion, renames and themes, and requires Read and modify. It reuses the existing plan and execute paths, so preflight, revision and permission checks, Undo and run records are unchanged, and no plan is retained.

Saving, export, deletions, imports, table and scientific operations keep the two-step form. A rejected apply reports that nothing was submitted. The connector instructions and the English and Simplified Chinese MCP references describe when to use it and how to recover after a disconnection.

Validation

• cargo pr-check
• npm run build in docs/
• Tests that apply produces the same result, revisions, run records and Undo steps as plan then execute, and that deletions, saves, imports, read-only access and stale revisions are refused without retaining a plan or changing the project.
