    "A1": {
      "claim": "Function is more stable than wrapper.",
      "detail": "We assume an entity's economic function changes more slowly than the legal or technical form it is delivered in. If this reverses (forms becoming more durable than functions), the primary spine should move to Layer 3 and the current spine demote to an attribute. What would break it: a regime where wrappers are permanent and functions are routinely re-pointed underneath them."
    },
    "A2": {
      "claim": "Model weights are durable, transferable assets.",
      "detail": "We assume frontier and open-weight models are held, valued, licensed, and transferred as assets distinct from their creators. If models become non-transferable in practice (pure hosted services with no assignable rights), the model-asset form collapses into a service revenue line under Layer 2 domain K and Module A is demoted."
    },
    "A3": {
      "claim": "On-chain settlement persists as a distinct property.",
      "detail": "We assume that whether a claim settles on a public ledger remains economically material (custody, finality, counterparty). If on-chain and off-chain settlement converge to indistinguishable risk, Layer 3's digital forms merge with their traditional analogues."
    },
    "A4": {
      "claim": "Machine and human readers must agree.",
      "detail": "We assume the standard's primary value is that an Overture agent and a DAP analyst reach the same classification. Every ambiguity is resolved by an explicit rule (Module C) rather than left to judgement. What would break it: definitions loose enough that inter-rater agreement falls, at which point the offending nodes are split or re-defined."
    },
    "A5": {
      "claim": "Public-domain-only lineage.",
      "detail": "We assume the standard must remain free of any proprietary commercial scheme's structure or naming, to be freely usable and defensible as DAP IP. Coverage completeness is checked only against public government concepts (activity families in the spirit of ISIC, NAICS, SIC), never against commercial taxonomies."
    },
    "A6": {
      "claim": "Compute is becoming a commodity with an independent, referenceable price.",
      "detail": "We assume standardised accelerator capacity trades as a fungible unit whose price is observable independently of any single provider's contract terms, and that the unit is durable enough to carry its own leaf. The leaf rests on the unit, not on any one venue, contract, or administrator. If this reverses, `K.04.05` is retired with a forward map to `K.04.01` and `T-COMPUTEMKT` retires with a forward map to `T-AICOMPUTE`. What would break it: the disappearance of every independently published capacity price and every venue trading a fungible unit, or a return to capacity sold only inside bundled, bespoke, non-transferable supply agreements. The withdrawal, non-approval, or illiquidity of any single listed contract does not break it; such an event is recorded against the affected contracts in `deriv_attrs` and in the review log, and the leaf stands. A6 is weaker than A1 to A5 and should be read that way: `K.04.05` was added on published daily benchmarks, spot venues, and announced listings rather than on a deep observed market, which is a deliberate and stated risk."

A portfolio can hold the exposure with no position in anything issued, and the standard must express that, on the same reasoning that separates a model asset from its developer in Module A.3."
