# Story Brief: When the Light Is No Longer Visible: IALA L1.4 and Expanding AtoN

## Core Premise

A research note on IALA’s L1.4 GNSS and e-Navigation course as contemporary context for invisible and digital Aids to Navigation, framed as interpretation rather than lighthouse heritage claims, with only a soft rhyme to LUX143.

## Story Shape

- Opening: identify the light, place, or object that anchors the story.
- Context: explain why the selected lights/assets are connected.
- Evidence: show the dated claims, source evidence, and unresolved gaps.
- Visual thread: use maps, timelines, object movement, and approved media only.
- Closing: state what remains to be reviewed.

## Warnings

- No warnings.
