# The graph is never committed — it is disposable and regenerated against
# whatever graphify version is installed. The fixture's .graphifyignore
# excludes all markdown/config, so this is a pure tree-sitter AST build:
# no LLM, no Ollama, reproducible.
#
# Sanity-checked invariant: lib/relay/delivery.rb must be exactly one graph
# hop from lib/relay/reports.rb (the R4 one-hop layout).
