HPD Environment Host Process

HPD-Environment.HostProcess executes sandboxed processes directly on the current host. It owns runtime-host and execution-unit identity, operating-system enforcement, network mediation, violation observation, process launch, and the initial host-path content-projection behavior.

Security posture

  • macOS uses Seatbelt through sandbox-exec when dependency checks pass.
  • Linux uses bubblewrap, namespaces, seccomp, and provider-mediated networking when the required kernel and executable features are available.
  • Windows is not registered as a sandbox backend. It fails closed until an accepted filesystem and network enforcement mechanism is implemented.
  • Agent permissions remain a separate decision layer. This provider enforces the compiled Environment isolation plan and does not inspect Agent prompts, tools, or conversation state.
  • A host-path projection cannot be remapped to a different destination path. Writable host-path projections require explicit direct-source mutation authorization.

Provider identity

hpd.execution.host-process

The provider supports the common RuntimeHost, ExecutionUnit, ProcessInvocation, ProcessIsolation, and ContentProjection contracts. Feature support is reported through ProviderCapabilityReport; required unsupported capabilities cause Agent Sandbox admission to fail before session creation.

Lifecycle

  1. Ensure the current host as a logical RuntimeHost.
  2. Ensure a logical ExecutionUnit attached to that host.
  3. Compile and apply the requested isolation policy when a process starts.
  4. Return the process handle and bounded output.
  5. Stop and delete processes, projections, the execution unit, and the host in dependency order.
