Project Vision & Master Architectural Scope
High-level architectural bounds and baseline principles governing the Property Valuation Simulator (PVS).
1. Executive Summary
This master architecture specification establishes the definitive standard for the Property Valuation Simulator engine. It serves as the immutable Single Source of Truth (SSOT) referenced across all calculation engines, database schemas, and client user experiences.
ISO 9001 Compliance Notice: This document is governed under strict change-control rules. Unauthorized modifications to formulas, node relationships, or baseline assumptions are prevented by gate locking protocols.
2. Scope & Target Allocations
The system is strictly partitioned into distinct subdomains to ensure isolation of concerns:
| Domain / Subdomain | Target Audience | Core Functionality |
|---|---|---|
pvs.fiscalstrategy.app |
Clients / Evaluators (Newland) | Interactive valuation workflows and simulation sliders. |
docs.fiscalstrategy.tech |
PMO / Auditors / Engineering | Controlled document repository and schema register. |
fiscalstrategy.org |
Regulators / Standards Bodies | Institutional governance and methodology whitepapers. |
3. Architectural Invariants
- Invariant A: Calculation engine inputs must resolve strictly against IOOI canonical nodes.
- Invariant B: Financial output models remain reproducible across all platform versions.
- Invariant C: All client exports maintain automated cryptographic hashes linked to this audit ledger.
