Deepens page ec-01

Finding the right file without reading every line

Instead of reading every file in "Meridian," the AI compares the meaning of a question against a map of what each file is about — the same nearest-neighbor idea used for documents, aimed at code. Pick a question and watch it light up the right file.

How it works

Meaning first, files second

positioned by meaning, not location
Every file gets a positionSimilar-purpose files end up near each other on the map.
your question the question lands somewhere on the same map
The question joins the mapPlaced by what it's asking about, not the words it uses.
the nearest files become the answer's source
Nearest winsThe closest files are what gets read — everything far away is skipped.

So what

The AI never "browses" the codebase — it jumps straight to the nearest match on a map it built once.
