- Audit — pluggable audit sinks (file, KV) and audit trail.
- Policy — policy engine governing what operations are permitted.
- Registry — auth profile store, context registry, engine registry.
- Browser-specific ports —
BrowserEnginePort,BrowserContextPort,BrowserAuthProfilePort,BrowserSearchPort,BrowserDownloadPort,BrowserExtractionTemplatePort,BrowserPolicyPort,BrowserAuditPort.
