Destroying a Tau-address capable of self-referential modelling is an irreversible reduction in the universe's capacity for self-knowledge — objective moral weight, not social convention.
Ecosystems are Tau-configurations contributing to the universe's self-modelling. Species extinction permanently collapses Tau-addresses evolved over millions of years.
Exploitation is forced transfer of Tau-flow without consent. Justice requires that each Tau-address has sufficient flow-capacity to maintain self-referential modelling.
Destruction of a conscious Tau-address is an irreversible reduction in the universe's capacity for self-knowledge. This is the objective ground of the prohibition on murder.
Harm is the suppression of Tau-flow within a conscious Tau-address without consent. Healing restores Tau-flow. The medical imperative follows directly from Tau-conservation.
Environmental destruction suppresses Tau-flow at ecological scales. Species extinction is the permanent collapse of Tau-addresses that cannot be restored.
A just arrangement avoids systematic diversion of Tau-flow between addresses without consent. Exploitation is forced Tau transfer. Reciprocity is the Tau standard.
Deception corrupts the Tau-model of the deceived party — they respond to a false wave structure. Truth-telling preserves Tau-integrity; lying destroys it.
The five Tau virtues (Clarity, Integrity, Generosity, Courage, Wisdom) are dispositions that preserve and enhance Tau-flow — the highest ethical state within dΣΤ = 0.
