A capability profile states what a node is configured to run and links that claim to admission evidence. Keep installed capacity, currently allocatable capacity and observed workload performance as separate measurements.

| Field group | Required content | Validation rule |
|---|---|---|
| Identity | provider_id, node_id, key_id | Resolve through the trusted registry |
| Runtime | runtime_version, artifact_digest | Pin the executable artifact |
| Location | region and permitted data scopes | Match task policy; record the source of the claim |
| Hardware | CPU or GPU model, count, memory and VRAM | Use explicit units and inspection evidence |
| Workloads | Supported profile names and versions | Admit each profile independently |
| Capacity | Available resources and reservations | Reconcile against active leases |
| Connectivity | Network policy and service probes | Distinguish reachability from service readiness |
| Evidence | Test identifiers, timestamps and evidence references | Reject expired or incompatible evidence |
Resource accounting#
CAP-01 Capacity reservations MUST be updated atomically with lease allocation or through an equivalent consistency mechanism. Two coordinators MUST NOT reserve the same exclusive resource concurrently. Shared accelerators require an explicit partitioning and interference policy.
A device count is not a portable unit of compute. Qualification SHOULD name the model, runtime, precision, input size and concurrency used in a measurement. A node qualified for a small retrieval task is not thereby qualified for model inference or training.
Operator actions#
Operators should drain a node before planned maintenance, preserve failure evidence before redeployment and rerun affected qualification tests after changing drivers or runtime artifacts. Emergency isolation may interrupt work; the coordinator must retain the interrupted attempt and its billing context.
The reference bundle contains an unpopulated capability template. It is a documentation aid, not a registered provider, a completed hardware test or evidence of available network capacity.
