Defined and tested before use.
Calculator workflows are released only after their required inputs, unit handling, output behavior, assumptions, limitations, and validation cases are documented.
Accuracy & validation
Know what the result represents and what it does not.
Crash Science records how technical work was produced, preserves the version used, and keeps limitations visible without treating software output as a substitute for professional judgment.
Reviewable by design
Professional output needs a recorded foundation.
Crash Science is designed to preserve the inputs, processing context, exact tool or model version, and stated limits behind an analysis. A result should remain understandable after the workspace is closed.
Display choices do not alter stored values.
Calculations and reusable case variables retain full precision even when the interface presents a shortened value for readability.
The version used stays with the work.
Saved calculations, measurements, figures, and reports retain the calculator, model, and calibration versions used at the time.
Software does not decide applicability.
Warnings and limitations support review, while the user remains responsible for evidence quality, assumptions, and professional interpretation.
Calculation transparency
The supporting work stays visible inside the member workspace.
Calculator results are presented with the recorded inputs, unit conversions, substitutions, intermediate math, full-precision result, and applicable warnings. Compatible saved results can be offered to a later calculation without silently changing their stored value.
Method details remain in the professional workspace, where they can be evaluated with the evidence and assumptions supporting the analysis.

3D vehicle validation
A verified reference belongs to one exact model version.
Before publication, a vehicle reference must have its orientation, pivot, tire-contact setup, ground plane, scale calibration, and standardized preview reviewed. A geometry or scale change requires a new model version and calibration record.
Prior cases and issued reports continue to reference the version they actually used rather than silently adopting a replacement.
One recorded reference establishes overall scale.
The calibration retains the known distance, unit, basis, verifier, verification date, and immutable identifiers.
Source quality and vehicle configuration still matter.
Trim, body configuration, ride height, accessories, aftermarket parts, damage, and manufacturing variation can differ from the reference.
Verification does not make the model an OEM record.
A calibrated reference supports technical inspection and measurement but does not prove that every surface or component is exact.
Method validation
Release requires documented behavior.
Production tools require known inputs, supported units, expected outputs, assumptions, limitations, and repeatable validation cases before member use.
Evidence and applicability
A valid calculation can still be misapplied.
Crash Science can check entries and preserve the work. It cannot determine whether the evidence, test conditions, selected method, or assumptions fit a particular collision.
Professional responsibility
Verify what is material to the opinion.
Independently confirm dimensions, evidence, and assumptions that materially affect repair, safety, engineering, testimony, or a legal conclusion.
Report integrity
Preserve the result with the record that supports it.
Issued reports retain frozen case data, exact version and calibration references, saved work, preparation time, and integrity hashes. The public sample uses simulated information to demonstrate the vehicle-measurement report structure without exposing a member case.
