We present SiriusA-PIC, a phase-invariant memory architecture that formalizes non-destructive integration at the commitment boundary. A global state S is updated by admissible, monotone, and inflationary deltas (ΔS) ; states are merged via a commutative, associative, and idempotent join (⊔), followed by commitment-bounded canonicalization (Canon). Operational equivalence is defined relative to commitment-relevant queries and commitment outcomes under the same admissible evidence. Canon collapses only distinctions irrelevant to commitment, while preserving all commitment-relevant structure. Safety is enforced at commitment via conservative aggregation: severity ordering (PASS 0 is acknowledged only as a prerequisite for later layers, and is not optimized or theorized in this version. This release consolidates and formalizes the core claims of Decision-OS V6 into a single, reviewable canonical edition. Lineage and Versioning This is Version 4 of the Decision-OS V6 (PIC) lineage. Version 1 introduced the breakout thesis. Version 2 refined the early structure. Version 3 provided an initial English canonical release. Version 4 provides the present consolidated and review-oriented revision, focusing on minimal formalization and commitment-bound structural clarity.
