A transient workspace governed by thermodynamic capacity ($\Delta T_{\text{max}} = \mathcal{C}\hbar / k_B$). Formulate rapid thoughts, uncommitted passwords, or raw proofs. If you abandon a thought, it physically dissipates into quantum entropy ($D_0 e^{-\lambda t}$). Anchor it before it fades to seal an immutable Tessere Imprint.
