Prime · interpret context with Beatrix Calculated context and help rules from a saved session. No language-model response or API connection is simulated. Spanish narration generated offline. Guided captures, not continuous screen recording. 1 · Select the context Select a signal and open the Beatrix tab. Help is linked to the selected signal and displayed result. Check the context before applying historical advice. The assistant must distinguish calculated facts from documentary proposals and highlight failed checks without independently changing signals, calibrations or results. 2 · Read the facts Open the detailed view to read position, width, map status and interpretation limits. Signal width alone is not enough to identify a polymer. A diffusion band is not automatically a species either. Use the help to decide what to inspect next, not as a replacement for scientific review. 3 · Check the sources Review possible assignments and their documentation. A matching chemical shift is a hypothesis: check other signals, couplings, solvent and shared diffusion. This video shows existing local context and rules. It does not present generative inference or claim that a documentary suggestion is confirmed chemical identification. 4 · Understand the limits Inspect assistance limits and configuration. Depending on hardware and settings, inference may use a CPU, a supported GPU or an authorized API. These resources are not activated or tested here. Scientific calculations and their states remain authoritative; a longer explanation does not remove uncertainty or validate a result.
