| purpose: > |
| Independent inventory of raw or source-emitted observables for large |
| training-run verification on monitored accelerator clusters. The inventory |
| lists observable data surfaces and feature values only. |
| |
| methodology: |
| organization: "One OXX-numbered list of positive observable surfaces." |
| use_case: > |
| Datacenter-observable activity, capability, timing, physical-state, |
| resource-use, and data-movement values inside a monitored boundary. |
| value_shape_policy: > |
| Feature values may be scalar time series, labeled count/rate tables, |
| coherent interval lists, or coherent event lists. Each value_schema lists |
| allowed feature value fields. Join keys, source record identifiers, source |
| URLs, exact asset IDs, administrative IDs, and ticket IDs are implementation |
| metadata outside the observable feature value. |
| |
| temporal_policy: |
| feature_temporal_kind_required: true |
| sample: "Point or periodic measurement with `sample_time`." |
| interval: "Value or state observed over a bounded window with `start_time` and `end_time`." |
| event: "Discrete source-emitted event with `event_time`." |
| validity_interval: "Capability, inventory, shape, or configuration state valid from `valid_from` until `valid_to`." |
| reference: "Source-backed reference value without operational event time; source versioning and retrieval metadata are implementation metadata." |
|
|
| scope_policy: |
| monitored_unit: > |
| Accelerator cluster, topology domain, rack-scale system, cloud placement |
| pool, provider-controlled capacity pool, or multi-site operator boundary |
| over a defined observation window. |
| include_if: > |
| The value is directly observed or source-emitted by a datacenter owner, |
| facility operator, cluster operator, cloud provider, storage/network |
| operator, monitoring system, or site-specific public/out-of-band source, |
| and it describes infrastructure activity, capability, timing, physical |
| state, resource use, or data movement. |
| |
| access_contexts: |
| public_or_out_of_band: "Site-specific public records, utility context, electrical permits, service records, and asset timing." |
| facility_operator: "Facility, rack, PDU, cooling, physical-security, BMS, DCIM, BMC, and change-management records." |
| cluster_operator: "Scheduler, orchestrator, accelerator telemetry, fabric, storage, monitoring, and maintenance records visible to a cluster operator." |
| cloud_provider_control_plane: "Provider records for compute provisioning, capacity reservation, placement, billing, audit, networking, and storage." |
| host_or_orchestrator_resource: "Host, VM, pod, container, cgroup, and infrastructure-only resource quantities." |
| storage_network_operator: "Filesystem, object-store, block, backup, replication, flow, fabric, route, and network-operation values." |
