PHI-OS
Persistent History
Injection OS

The governance layer beneath sirius-lab. Not a product — a published architecture.

PHI-OS is the persistent history injection layer that powers MoCKA's governance loop. It defines how AI systems can be made structurally incapable of ignoring their history.

§
Silence Prohibition Protocol and Persistent History Layer:
A Formal Governance Architecture for AI Behavioral Accountability
Masahito Kimura · Under peer review · Zenodo preprint

This paper proposes PHI-OS — a system-level architecture that makes AI history injection a structural property of the operating environment, not an application-layer convention. The Silence Prohibition Protocol (SPP) ensures AI systems cannot produce outputs that lack a verifiable trace to prior context.


Architecture

The PHI-OS Layer Model

PHI-OS sits between human input and AI response, enforcing governance invariants at the OS layer — where they cannot be bypassed by application code.

Core Concepts

What PHI-OS Defines

Silence Prohibition Protocol (SPP)

A formal protocol that prevents AI outputs from existing without a verifiable trace to prior context. Silence — the absence of recorded reasoning — is treated as a governance violation.

Persistent History Injection

Every AI session receives a structured injection of verified prior history before processing. This is enforced at the OS layer — below application code.

Context Verification

Before any AI operation executes, PHI-OS verifies that the injected context is authentic, complete, and unmodified — using cryptographic attestation.

Shadow Movement

PHI-OS implements a dual-path architecture. Under partial failure, the system degrades gracefully to a minimum operating capability (~75%) rather than stopping.
