Compute Product ID Migration

This note defines the canonical compute-product namespace introduced for the Psionic-owned compute family tree.

Canonical Format

Compute product IDs now follow:

psionic.<provisioning>.<family>.<implementation>.<topology>

Rules:

• provisioning describes where the product is admitted from:
  • local
  • remote_sandbox
  • later: cluster
• family describes what is being sold:
  • inference
  • embeddings
  • sandbox_execution
  • later: evaluation, training, adapter_hosting
• implementation is the backend family for model-serving products or the execution class for sandbox products.
• topology names the truthful execution topology exposed in the capability envelope.

Current Canonical IDs

Old ID	Canonical ID
legacy_local_runtime.text_generation	psionic.local.inference.gpt_oss.single_node
gpt_oss.text_generation	psionic.local.inference.gpt_oss.single_node
legacy_local_runtime.embeddings	psionic.local.embeddings.gpt_oss.single_node
gpt_oss.embeddings	psionic.local.embeddings.gpt_oss.single_node
apple_foundation_models.text_generation	psionic.local.inference.apple_foundation_models.single_node
sandbox.container.exec	psionic.remote_sandbox.sandbox_execution.container_exec.sandbox_isolated
sandbox.python.exec	psionic.remote_sandbox.sandbox_execution.python_exec.sandbox_isolated
sandbox.node.exec	psionic.remote_sandbox.sandbox_execution.node_exec.sandbox_isolated
sandbox.posix.exec	psionic.remote_sandbox.sandbox_execution.posix_exec.sandbox_isolated

Compatibility

• Kernel-side canonicalization accepts both canonical IDs and the historical launch aliases above.
• Provider-substrate emits canonical IDs for newly-derived products, but still recognizes historical aliases when reading existing state or tests.
• Desktop launch bindings now emit canonical inference product IDs.

Forward Examples

These are naming targets, not implemented product families:

• psionic.cluster.inference.gpt_oss.tensor_sharded
• psionic.cluster.inference.gpt_oss.pipeline_sharded
• psionic.cluster.training.gpt_oss.training_elastic
• psionic.cluster.evaluation.apple_foundation_models.replicated

The product ID should say what market object is being sold. Detailed runtime facts still belong in the capability envelope, delivery proof, and evidence.
