Clear boundaries

This preview was verified on one Mac with Numbers 14.5. Other versions are not certified. Numbers does not expose arbitrary chart type, series, axis or internal-title editing; template-linked charts preserve known native links. Operations can partially apply and have no automatic rollback. Imports are bounded to a 2,000-cell resulting table.

The bridge has no telemetry or direct network upload. Tool data still passes through the host and its model under the host's policies. Read the privacy policy and verification report.
