AGENTIC COMPANY SERIES

The blueprint for building an Agentic Company

Eight papers that form the complete theory-to-operations stack: why organizational judgment needs an OS, structural design, stability laws, algorithm architecture, mission-constrained optimization, survival optimization, workforce transition, and agent lifecycle management.

Series Thesis

Company Intelligence explains why the OS exists. Structure defines responsibility. Stability laws prove when governance holds. Algorithms make it executable. Mission constraints keep optimization aligned. Survival theory determines evolutionary direction. White-collar transition shows who moves first. VITAL keeps the whole system alive.

Audit Universe Runtime: Agent Design for Executing Audit Procedures as Runtime Operations

Transforming ISA/JICPA standards into executable agent specifications — from sampling strategies to substantive testing, within a MARIA OS governance architecture

Traditional audit procedures are encoded in prose-based standards that resist automation. This paper presents the Audit Universe Runtime — a multi-agent execution environment within MARIA OS that compiles audit standards (ISA, JICPA) into executable agent task specifications. We formalize audit procedures as state machines, design sampling strategy agents with statistical rigor, implement real-time anomaly detection during substantive testing, and prove audit completeness through a formal coverage model. The architecture maps MARIA coordinates to engagement structures, enabling continuous auditing with immutable audit trails and human-agent collaboration gates at every materiality threshold.

Audit Universe Runtime:監査手続をランタイム・オペレーションとして実行するAgentアーキテクチャ

ISA/JICPA基準をエージェント実行仕様に変換する — サンプリング戦略から実証的テストまで、MARIA OSガバナンスアーキテクチャの中で

従来の監査手続は、自動化に抵抗する散文ベースの基準書に記述されている。本論文では、MARIA OS内のマルチエージェント実行環境であるAudit Universe Runtimeを提示する。ISAおよびJICPA基準を実行可能なエージェントタスク仕様にコンパイルし、サンプリング戦略エージェントを統計的厳密さで設計し、実証的テスト中のリアルタイム異常検知を実装し、形式的なカバレッジモデルを通じて監査の完全性を証明する。このアーキテクチャはMARIA座標をエンゲージメント構造にマッピングし、すべての重要性閾値における人間-エージェント協働ゲートと不変の監査証跡による継続的監査を可能にする。

Evidence Coherence Spectral Analysis: Detecting Fraud Through Eigendecomposition of Audit Evidence

Using spectral methods on evidence correlation matrices to identify inconsistencies, fabrication patterns, and systemic fraud signals

Traditional audit systems often rely on rule-based checks and statistical sampling, which can under-detect coordinated fabrication patterns. This paper introduces Evidence Coherence Spectral Analysis, a framework that treats evidence sets as vector spaces, builds correlation matrices from evidence attributes, and applies eigendecomposition to identify anomalous spectral gaps associated with inconsistency or fabrication risk. We define a coherence score, relate it to false-discovery behavior, and describe integration with MARIA OS Evidence Bundles. In controlled financial-statement audit experiments, spectral analysis detected 94.7% of fabricated evidence sets while maintaining a false-positive rate below 2.3%, with streaming support for near-real-time analysis.

Audit Stopping Criteria: Mathematical Foundations for Knowing When Enough Is Enough

Defining audit termination conditions through MAX constraints and probability thresholds to minimize False Allow Rate

Every audit faces the same question: when is evidence sufficient to stop? Stopping too early can allow defects to escape into production, while stopping too late consumes budget and attention with diminishing returns. This paper formalizes audit stopping criteria as a constrained optimization problem, derives solutions under MAX constraints and sequential probability ratio testing, and describes integration with the MARIA OS Fail-Closed Gate Engine. In evaluated SOX workloads, the approach reported a False Allow Rate below 0.3%.

Auditable Financial Decision Traceability: Evidence Graph Models for Regulatory Compliance

Formal evidence graph construction and matrix-algebraic traceability for reconstructing every financial decision under SOX, Basel III, and MiFID II

Regulatory reconstruction of AI-driven financial decisions is difficult when logs are fragmented, timestamps drift, or causal links are missing. This paper introduces a formal evidence-graph model where each decision is an immutable node in a directed acyclic graph, linked by typed causal edges with cryptographic evidence bundles. We define `TraceCompleteness` as `TC = |reproducible decisions| / |total decisions|` and report `TC >= 0.997` across evaluated SOX, Basel III, and MiFID II audit scenarios.
