   4  Cleanup item: the load-bearing δ certificate.
   5
   6  The flagship credibility does not need the ~500-field open-targets object. The
   7  δ claim rests on four independently substantive proved statements. This module
   8  is the small conjunction that actually carries the program, each conjunct a
   9  headline theorem proved with no project-local axioms and no sorry:
  10
  11    (A) ONE PRIMITIVE. The same/different judgment is derived from the act, not a
  12        second primitive (`OnePrimitive.comparison_is_derived_not_primitive`).
  13
  14    (B) COST FORM, FREE UNIT. δ forces the cost form (a faithful one-parameter
  15        gauge family); the unit is the single residual free positive real; J is
  16        the curvature-1 member (`Calibration.calibration_unit_is_a_gauge`).
  17
  18    (C) BELOW THE CONTINUUM. Every named RS constant lives in one countable
  19        subfield of ℝ that is a proper subset of the continuum
  20        (`MinimalField.rs_physics_below_continuum`).
  21
  22    (D) CHAIN FED BY δ. The RS forcing chain's cost entry is the calibrated δ
  23        cost, and its φ output lives in the countable field
  24        (`ChainBridge.delta_cost_feeds_rs_chain`).
  25
  26    (E) SCAFFOLD ON THE COUNTABLE CARRIER. The whole working machinery, every
  27        integer power of φ (the mass ladder) and the chain's integer outputs
  28        (eight-tick 8, dimension 3), are elements of the countable field
  29        (`MinimalField.rsField_phi_zpow`, `rsField_eight_tick`,
  30        `rsField_dimension`). The chain runs end to end below the continuum.
  31
  32    (F) OPERATIONS BELOW THE CONTINUUM. One countable subfield of ℝ is closed
  33        under exactly the operations the constants are built from (field ops,
  34        exp, log) and already contains π, φ, e, and α⁻¹
  35        (`ExpLogField.rs_operations_below_continuum`). The construction, not just
  36        the answers, stays inside a countable field.
  37
  38    (G) DISTINCTION IS NOT OPTIONAL. Any foundation with a reflexive expression
  39        order is either degenerate (distinguishes nothing, cannot do mathematics)
  40        or realizes the δ core (`DistinctionDichotomy.distinction_dichotomy`).
  41        Every foundation that can express a single non-trivial distinction
  42        contains δ.
  43
  44  This is the certificate to cite for "what δ establishes". It is small enough to
  45  read in full (seven conjuncts) and every conjunct is load-bearing.
  46
  47  No project-local axioms. No sorry.
