Academic Notes 2.10.0

• Fix raw LaTeX labels in commutative diagrams when the host renderer supplies CommonHTML or is unavailable. A private bundled TeX/AMS-to-SVG fallback preserves the shared coordinates, with initialization deferred until needed. Bare TeX, dollar delimiters and LaTeX delimiters are supported.
• Add short curved commutativity arrows inside triangles. Connect the two-step path and direct arrow, choose Mark commutativity, then click source, intermediate node and target.
• Support touch selection, deletion and undo for markers; remove dependent markers when nodes, arrows or grid positions are removed. Existing diagrams remain compatible.
• Update English and Chinese usage guides, the tensor-product example, illustration and MathJax Apache-2.0 notices. No runtime downloads or new network/filesystem permissions.

Validation: 20 Node regressions, mobile release-bundle loading, real SVG/CommonHTML and unavailable-renderer tests, diagram touch editing, responsive coordinates, and actual PDF links, pagination and isolated printing. Physical iPad verification remains separate.

The three installation assets are built by GitHub Actions and include artifact attestations.
