Equation-backed demos
A startup demo becomes more credible when motion, scale, and measurements are reproducible from equations or catalog values.

Model policy
Text is not the proof layer
When this note discusses simulated movement, scale, spacecraft geometry, or astrophysical structure, the proof is delegated to the relevant mathematical model page or simulator section. The blog does not treat screenshots as theory.
Key Points
Practical reading notes
Operational boundaries
Public simulators should label where they use educational approximations instead of flight-grade propagation or certified engineering data.
Sellable learning layers
Interactive maps, calculators, and model viewers can become products when assumptions and limitations are visible to buyers.
Where To Continue
Pages with the actual equations
Mathematical model
Page model status
This page does not introduce a standalone generated physics or engineering simulation. Any decorative background or static illustration is presentation only; mathematical claims must come from the cited equations, catalog values, or linked model-verification pages.
No image-derived claim
\[\text{visual decoration} \ne \text{physical model}\]
Decorative images, icons, and background effects on this page are not used as evidence for a scientific or engineering statement.
Content claim standard
\[\text{claim} \rightarrow \text{source field or equation}\]
If the text gives a quantitative fact, it must be traceable to a data field, unit conversion, or equation on the relevant detailed page.
Model handoff
\[\text{open } \mathtt{/model\text{-verification/}}\]
Interactive pages linked from here carry their own mathematical model sections with equations, assumptions, proof notes, and limitations.
Verification standard: the rendered object must be reproducible from stated equations, catalog parameters, or explicit geometric transforms. Visual reference images may inform presentation only; they are not the source of orbital positions, field vectors, accretion-disk gradients, timing, or engineering layout.
Limitations: browser scenes may use bounded scale, compressed distances, simplified two-body dynamics, schematic transfer curves, or educational approximations where full numerical ephemerides, CFD, finite-element models, or general-relativistic ray tracing are outside the page scope. Those simplifications are part of the model contract, not hidden image-based construction.
