Fairness (CI-protocol)

Fairness, in the τ-framework, is the categorical-imperative protocol over Reg_C: a τ-categorical procedure where every commitment-stance is tested for universalizability and dignity-preservation under permutation of label-coordinates. Fairness is not an additional axiom — it is a structural consequence of Commitment Register Admissibility plus dignity (label-independence) plus no-conflict.

Categorical invariant. Fairness = the protocol Φ : Reg_C → Reg_C that returns the universalizable, dignity-preserving sub-section of every commitment-stance; equivalently, Φ is the equalizer of the CI-action and the dignity-action on Reg_C.

Fairness is instantiated whenever a commitment is tested by asking: 'Could every relevantly-similar agent take this stance, and does the stance preserve dignity for all parties?' Examples: Rawlsian veil-of-ignorance reasoning; impartial juror selection; algorithmic-bias audits that test classifier outputs under label permutation.

Examples:

• Rawlsian original position — universalizability test as procedural device
• Blind grading and double-blind peer review — fairness via label-removal
• Algorithmic-bias audits — testing classifier stability under demographic relabeling
• Citizens' assemblies and lottocratic juries — universalizability via random stance-sampling
