# Exact integer-grid polyline simplification

Build-time release reference. Runtime readiness, deployment, payment settlement and external indexing are not evaluated here. Prices are proposed; this file cannot authorize execution or payment.

Simplify a supplied integer polyline with exact point-to-segment Ramer–Douglas–Peucker decisions, original retained indexes and per-final-segment squared vertex-deviation witnesses.

Release: 0.29.0. Built: 2026-10-06T15:38:00Z.

## Choose for
- Reducing original-vertex polylines for previews or vector exports
- Requiring exact inclusive tolerance decisions and earliest-index distance ties
- Checking original removed vertices against their final enclosing segments

## Outside this profile
- Minimum-vertex optimization, topology or area preservation
- Curve smoothing, map matching or global geometry equivalence
- General Hausdorff certificates, geodesic distances or coordinate conversion
- Fetching sources, changing external state or executing supplied data

Proposed nominal USD 0.005 per successful call; payer fees excluded. No verified runtime availability.
