# Panorama Stitching Field-of-View Planner implementation

A source-bound implementation contract for Panorama Stitching Field-of-View Planner; 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**: t5-067

**Effect**: Computation or source lookup only

## Input and validation requirements

A 100% overlap input makes the effective angular-step denominator zero and produces a non-finite frame count in JavaScript. Treating the percentage value 20 as a raw fraction also produces a negative angular step and an invalid frame count.

## 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.
