package/store/_README-neighbours.md

The neighbours file's own dictionary entry, with its counts.

What it holds

A section on neighbours.jsonl: ordered room pairs that touch, each written both ways; how many share an artwork, border on the atlas outline, overlap, are named in the coders' record, or are both on the canvas and named; rooms with at least one neighbour; artworks with an outline and a room of the frame; atlas entries not joined by name. Then the limit: "a border is where two outlines meet, not a negotiation. A mention is a pointer a coder recorded."

Who writes it, and when

build_neighbours.py, handler side, when build.sh finds INPUT/canvas/atlas_2017.json; build_store.py --readme-only then folds it into README-store.md.

Why it exists

build_neighbours.py states the limits in its docstring: the atlas outline is one annotator's, drawn after the event, and pixels are counted on the outline, not recounted from the placement log.
