Module base Architecture

Architecture - Base Module

Overview

The base module is the runtime foundation for module extensibility. It composes loading, validation, dependency resolution, isolation, and reload behavior into a single platform-facing layer consumed by other modules.

Main Execution Planes

1. Loader and trust plane

• dynamic module load/unload lifecycle
• trust, integrity, and policy gating before activation

2. Dependency and registry plane

• dependency graph and compatibility ordering
• remote registry retrieval and validation path

3. Isolation and runtime plane

• module sandbox boundaries and limits
• wasm isolation and runtime injection hooks

4. Reload and operations plane

• hot reload with rollback semantics
• observability and runtime status surfaces

Core Contracts

Contract	Behavior
loader interfaces	validate and activate/deactivate modules safely
dependency interfaces	express and resolve load order constraints
sandbox interfaces	enforce bounded execution policies
reload interfaces	coordinate swap/rollback without full restart

Failure Semantics

• invalid or untrusted module artifacts fail closed during load.
• dependency/compatibility conflicts return structured resolution failures.
• sandbox/runtime setup failures block unsafe execution paths.

Sourcecode Verification (Module: base/architecture)

• Verified files:
  • src/base/module_loader.cpp
  • src/base/plugin_dependency_graph.cpp
  • src/base/module_sandbox.cpp
  • src/base/wasm_plugin_sandbox.cpp
  • src/base/wasm_runtime_injector.cpp
  • src/base/hot_reload_manager.cpp
  • src/base/remote_registry_client.cpp
• Verified architecture claims:
  • explicit loader, dependency, isolation, and reload planes
  • bounded failure behavior around trust and runtime activation
  • dedicated base-layer composition for extensible modules
