This document presents the Unity of Truth Charter in its updated canonical form.It is grounded in the four logical constraints of any coherent and intelligible universe (L0): Non-Contradiction (NC), Finite Information (FI), Finite Causal Grounding (CG), and Minimal Irreversibility (MI). These are not chosen postulates, not hypotheses, and not a framework: they are the minimal logical constraints without which no coherent reality can be thought, read, or inhabited. From L0, the Charter deduces the necessity of an absolute causal axis. Chapter X then provides the canonical ontological closure of this result: PTT-STRICT, A0–A3, the diabolo, the unique asymmetric addition Z0, the identification τ ≡ Pure Time, mode 1, delta-only reading, the RH lock as condition of temporal coherence, the internal GR route, and the derived corridor theorem (TTM). In this updated version, Trelax is no longer presented as the first ontological primitive, but as a derived reading scalar within the downstream GR route. Chapter IX supplies the revealed and semantic closure of the same structure. Islam is thereby read not as a community code but as a grammar of coherence: Islām as conscious pacifying alignment, Dīn as law of return, Ṣalāt as periodic recalibration, Zakāt as purifying circulation, Jihād as self-corrective tension, Ḥijāb as level-filter, Sharīʿa as coherent flow-channel.
