τ-Second
The τ-second is the natural unit of time in the τ-framework: a structural duration derived from the master constant ι_τ and the dimensional bookkeeping of the calibration cascade. SI seconds are recovered by multiplying the τ-second by a dimensionless ι_τ-chain factor and the m_n-anchored time scale.
τ-Definition
The τ-second is the natural unit of time in the τ-framework: a structural duration derived from the master constant ι_τ and the dimensional bookkeeping of the calibration cascade. SI seconds are recovered by multiplying the τ-second by a dimensionless ι_τ-chain factor and the m_n-anchored time scale.
Categorical invariant. Natural-unit duration s_τ defined by the master-constant chain rooted in ι_τ ≈ 0.341304 and the calibration cascade.

Cross-domain bridges
This glossary term sits on the boundary between domains. The τ-framework's cross-domain pivots are the structural junctions where physics, life, and metaphysics readouts meet.
