Characteristic Drift Time Scale

The Characteristic Drift Time Scale is the time constant τ⤳ that sets how fast entropy approaches its maximum as phase drift accumulates in the evolving substrate. The book treats entropy as phase evolution: as the phases of Pulse elements drift apart from an initially aligned state (entropy zero, all phase differences zero), entropy climbs exponentially toward its maximum, and τ⤳ is the timescale of that climb. It links microscopic phase dynamics to macroscopic thermodynamic behavior. The climb is not permanent: a Data Nova acts as a computational reset event that returns terminal entropy to zero, S◁ → 0 via Data Nova → S▷ = 0, which the book reads as a cosmic rebirth mechanism. The book writes the evolution it governs as S(t) = S⥣ × [1 − exp(−t/τ⤳)], where S(t) is the time-dependent entropy [∅], S⥣ the maximum possible entropy [∅], t time [𝕋] and τ⤳ the Characteristic Drift Time Scale [𝕋]. The current lexicon statement adds that τ⤳ = 1/(α⤳ × ⟨ℜ²⟩), tying it to a drift coefficient and the mean squared recursive tension. The Characteristic Drift Time Scale connects to Phase Drift Propagation, Entropy States, Critical Entropy Threshold, Data Nova, BPT Temperature Analog and Entropy Accumulation.
