Generated graphs

Graphviz artifacts generated by make graphs. Use these alongside the API, contract, and registry pages to navigate module dependencies, subsystem boundaries, and first-party extension registration sites.

Summary

Generated graph summary #

Generated by scripts/docs/gen-graphs.fnl.

Artifacts #

• docs/graphs/modules.dot — tracked full module dependency graph.
• docs/graphs/modules-clustered.dot — tracked graph with subsystem clusters.
• docs/graphs/subsystems.dot — tracked collapsed subsystem graph.
• docs/generated/graphs/contributions.dot — ignored static extension contribution graph.
• docs/generated/graphs/extensions/*.dot — ignored per-extension local graphs.
• docs/generated/graphs/modules/*.dot — ignored per-module focused graphs for static HTML docs.
• SVG renderings are generated locally by make graphs but are not tracked.

Legend #

• pale green nodes: reloadable modules
• light yellow nodes: persistent/source modules
• light cyan component nodes: scripts or C/bootstrap sources
• gray dashed ellipse nodes: external or native modules
• red nodes/edges: load-time strongly connected component membership
• dashed gray edges: macro or late require edges
• dotted gray edges: optional pcall require edges
