Architecture and Package Boundaries

• graph owns immutable graphs, stable ports, deterministic analysis, and scheduling.
• lua/compiler owns validation, SHA-256 hashing, and prototype caching.
• lua/runtime owns per-computer VMs, transactional node instances, coroutines, and state serialization.
• lua/sandbox owns globals and instruction budgets.
• lua/node owns schemas, the fluent contract, bundled definitions, and embedded libraries.
• lua/endpoint owns safe Java registrations and preview fixtures.
• client/editor owns explorer and focused editor state.
• client/renderer/node owns the semantic palette and shared layout.
• persistence owns format 3 and the clean legacy reset.
• network remains authoritative for distance, permissions, revisions, and payload size.
• integration/computercraft, integration/create, integration/aeronautics, integration/jade, and integration/wthit own optional API boundaries and lifecycle cleanup.

Minecraft and addon objects stop at endpoint handlers. Lua nodes communicate through scheduler-owned edges, never by directly calling neighbors. WireEditorController remains the unchanged compatibility boundary for curves, colors, thickness, pulses, waypoints, hit testing, and socket behavior.

Format 3 stores one root graph, an embedded Lua library, definition ID/hash references, stable port snapshots, persistent state, revision, and metadata. It stores no Functions or Sections.
