v1.3.0

Added

• A strict, digest-sealed MIF merge-compression adapter that accepts canonical
  SCPN-MIF-CORE observation bytes, validates exact reactor identity, event and
  simulation clock, source revision, kinematics, geometry, lock/trigger/gate
  predicates, and provenance, and preserves oscillator coordinates as
  simulation-only numerical_phase. Translation, compression, lock, trigger,
  and gate values remain bounded or categorical; no control action is created.
• Versioned cross-reactor semantic-ingress, observability, regime-axis, and
  mode-identity registries covering all 32 built-in configurations. They keep
  undeclared producers, non-applicable axes, unknown state, physical modes,
  and numerical oscillator coordinates distinct and review-only.
• A portable, digest-sealed eight-axis ReactorRegimeAssessment contract that
  separates ontology-derived static applicability from classified, unknown,
  and not-applicable results. It binds exact source, clock, validity, registry,
  typed evidence-role, classifier, threshold, uncertainty, quality, and
  provenance identities while remaining review-only and non-actionable.
• A digest-sealed ReactorResearchControlIntent hypothesis contract with
  evidence-bound candidate envelopes, device-contract limits, complete clock
  identity, restricted research-safe target vocabulary, and mandatory future
  CONTROL, adapter, operator, and machine-protection review. It cannot execute
  or grant actuation authority.
• A strict public coupled-transport adapter that accepts canonical FUSION TORAX
  review bytes, validates the complete clock, reactor, shape, unit,
  calibration, numerical-refinement, provenance, and digest contract, and maps
  exactly four profiles, five source totals, and three state budgets to
  noncyclic U0 review evidence. It never infers phase, regime, or action.
• A digest-sealed, review-only reactor semantic handoff that preserves exact
  FUSION producer bytes, registry-validated U0 contracts, simulation clock and
  event identity, bounded-feature semantics, and an explicitly unknown regime.
  It rejects phase relabeling, relations, digest/version drift, mixed clocks,
  and any authority or action escalation.
• U0 reactor-family-neutral semantic contracts for context, calibrated
  observables, typed phase meaning, compatible phase relations, and
  compositional review-only regime estimates. The contract distinguishes eight
  semantic carriers, spans nine reference reactor families, serializes
  deterministically, and fails closed on missing, stale, OOD, incompatible, or
  below-threshold evidence without granting SPO actuation authority.

Changed

• Tag-triggered Python package and GitHub release workflows now use one
  fail-closed reproducible artifact builder. It derives a fixed epoch from the
  exact source commit and canonicalizes sdist archive metadata so repeated
  wheel and sdist builds have stable SHA-256 values.
• Package-root compatibility exports now resolve lazily, so importing the
  portable reactor-semantic byte codec does not initialise UPDE, supervisor,
  native accelerator, or Julia runtimes. The frozen root __all__ contract is
  unchanged.
