Conventional-tokamak physical-payload request

SPO materialises the L1_extend_exercised_review_adapter next boundary as the digest-sealed schema scpn-phase-orchestrator.conventional-tokamak-physical-payload-request.v1 version 1.1.0. The public builder is conventional_tokamak_physical_payload_request().

The request binds the existing SCPN-FUSION-CORE TORAX adapter, source schema, handoff schema, semantic profile, semantic-profile registry, and observability registry. This binding proves that a byte-canonical producer-to-SPO review path exists. It does not convert TORAX simulation output into a physical sample: source_kind=simulation, physical_source_present=false, and reusable_as_physical_evidence=false are fixed contract members.

Producer obligations

SCPN-FUSION-CORE must allocate a configuration-specific canonical physical payload and satisfy all thirteen prerequisites:

  1. immutable physical sample identity and sampled values;
  2. conventional-tokamak-specific diagnostic, channel, geometry, and frame identity;
  3. controlled phenomenon identity and semantic carrier;
  4. physical reference identity;
  5. diagnostic-to-facility and event clock correlation;
  6. a validated observation operator or calibration lineage;
  7. uncertainty;
  8. validity;
  9. distinct producer evidence-state semantics for unknown, out_of_distribution, low_observability, and stale;
  10. provider and derived quality semantics;
  11. immutable provenance and reproducibility, including source and package identity;
  12. a predeclared and evaluated observability gate; and
  13. independent validation without same-shot circularity.

The four evidence dispositions describe why current plant truth cannot support a physical classification. They map to U0 validity unknown, out_of_distribution, unobservable, and stale, respectively, and every mapping forces an unclassified RegimeState.UNKNOWN result. They are not plasma modes or operating regimes. Provider quality is orthogonal and cannot replace the disposition; a merely small score above a predeclared observability gate is not low_observability.

The four applicable catalogue entries are carried as unselected candidate requirements: equilibrium profiles, a recurrent transient, a resolved MHD mode, and the simulation-only synthetic oscillator coordinate. Applicability is not evidence. New peer discoveries enter the atlas as gaps or provisional candidates and require a versioned registry change before this request can reference them canonically.

Authority boundary

The request fixes selected_candidate_id=null, physical_payload_schema_allocated=false, physical_source_present=false, observation_admitted=false, phase_inference_eligible=false, producer_evidence_state_contract_present=false, quality_state_may_substitute_for_evidence_state=false, semantic_ingress_extended=false, control_admission_requested=false, actionable=false, execution_permitted=false, and direct_actuation=false. It is review-only and machine protection retains the final veto.

Neither the external technology rank, the accepted SCPN-TOKAMAK-CORE design plan, the existing simulation adapter, nor this request may be consumed as a physical observation, physical phase, CONTROL intent, action, execution, or actuation authority.

The normative JSON Schema is conventional_tokamak_physical_payload_request.schema.json. The canonical producer-priority register pins request ID fec4e93971190c7183410f200c60a9ef0ffcfeaf01fa69f9fc3514e9e352603c and complete envelope SHA-256 a506c0ad7c37ee53719b3f2194906b39585e4293e1c5f9d25245f987c0b08945.
