  Sparse capacity and capability screens for settings where only one or two raw
  observable feature families are present. These rules emit narrow capacity,
  availability, topology, power-service, or policy-scale feasibility statements.
  They do not emit workload identity or achieved-work labels.

    This file supplies sparse capacity facts and screens for the public
    aggregation layer. Strong rule-out claims are made by derived capacity
    bounds plus `aggregation_rules.yaml`, not by single sparse screens.
  sparse_claim_policy: >
    A sparse capacity rule may say that an observed feature is compatible with,
    limits, or routes review of threshold-scale capacity. It must not say that
    work occurred, that training occurred, or that no hidden/out-of-scope
    capacity exists.
