Module plugins Architecture

Architecture - Plugins Module

Overview

The plugins module composes plugin lifecycle orchestration, manifest/security validation, hot-plug monitoring, health/metrics reporting, and remote repository integration into a bounded extension subsystem for ThemisDB.

Main Execution Planes

1. Lifecycle and registry plane

• plugin load/unload/reload orchestration
• plugin registration and capability/edition gating

2. Security and validation plane

• manifest parsing and signature verification
• capability validation and runtime compatibility checks

3. Monitoring and integration plane

• plugin metrics, health monitoring, and hot-plug behavior
• OCI/rpc and WASM-related integration surfaces

Core Contracts

Contract	Behavior
lifecycle contract	deterministic plugin state transitions and rollback behavior
security contract	explicit manifest/signature/capability enforcement
monitoring contract	bounded health and metrics reporting behavior
integration contract	deterministic repository/rpc/runtime integration behavior

Failure Semantics

• invalid manifest/signature/capability input fails with explicit outcomes.
• reload failures preserve deterministic fallback behavior.
• unavailable integrations are surfaced as explicit errors.

Sourcecode Verification (Module: plugins/architecture)

• Verified files:
  • src/plugins/plugin_manager.cpp
  • src/plugins/plugin_registry.cpp
  • src/plugins/plugin_hot_plug_monitor.cpp
  • src/plugins/plugin_health_monitor.cpp
  • src/plugins/signed_plugin_repository.cpp
  • src/plugins/oci_registry_client.cpp
• Verified architecture claims:
  • explicit lifecycle/security/monitoring/integration planes
  • deterministic failure boundaries across plugin workflows
  • module-local ownership of plugin orchestration behavior
