Module context 

Context module - Execution context types

This module provides the context types passed through all execution:

• TenantContext: Multi-tenant isolation boundary (REQUIRED)
• RuntimeContext: The execution spine
• TraceContext: W3C distributed tracing
• InvocationContext: Agent/tool invocation context

Key Invariant: TenantContext is Required

Every execution MUST have a TenantContext. This ensures:

• Multi-tenant isolation
• Resource limit enforcement
• Audit compliance
• Billing attribution

Usage

use enact_core::context::{TenantContext, RuntimeContext};
use enact_core::kernel::{ExecutionId, ParentLink, TenantId, UserId};

// Create tenant context (REQUIRED)
let tenant = TenantContext::new(TenantId::from("tenant_acme"))
    .with_user(UserId::from("usr_alice"));

// Create runtime context with tenant
let ctx = RuntimeContext::new(
    ExecutionId::new(),
    ParentLink::from_user_message("msg_123"),
    tenant,
);
