# Link a project's graphify graph into the CENTRAL brain.

# Usage:
#   ./brain/graph/link-project.sh <project-name> <path-to-graph.json>
#
# Copies the project's graph.json into brain/graph/projects/<name>.json and
# records it in brain/graph/projects/registry.json, then rebuilds the central
# brain. The central brain is a merged cross-repo graph, so projects stay
# independent on disk but roll up into one queryable brain.
