# Kinematics — Uniformly Accelerated Motion Solver implementation

A source-bound implementation contract for Kinematics — Uniformly Accelerated Motion Solver; deployment and executable qualification remain separate.

Status: **VERIFIED_CLEAN**Lifecycle: **implementation-contract**

## Binding contract

This record describes what an executable surface must bind and validate. It does not claim that a public calculator, package, or production route is deployed.

**Record owner**: Guth Instruments

**Lifecycle**: verified-clean

**Evidence ID**: t4-202

**Effect**: Computation or source lookup only

## Input and validation requirements

The input v0=5, v=5, t=0 creates a 0/0 division when solving for acceleration. Acceleration is undefined and the instrument should reject the acceleration result rather than return a numeric value.

## Required corrections

No binding erratum is attached to this unique-name record. Implementers must still preserve the declared units, domain, and failure behavior.

## Inspectable interface fixture

The sample below is evidence for interface and validation tests, not a production implementation.
