# Section 43 — Map Module (locally ratified in OSCR-)

**Date:** 2026-06-29

## 43.1 — SVG-based rendering.
No Leaflet dependency. Sovereign SPA mode = bundle stays lean.

## 43.2 — 3 geometry types.
Point, line, polygon.

## 43.3 — Tree ↔ map integration.
Trees have lat/lng in their profile; map_layers can link to a tree via linked_artefact_id.

## 43.4 — Drawing layers are project-scoped.
All layers belong to a project.
