# ZTDS.ai — Zero-Trust Data Sanitization Architecture & Standard (2026 Corpus)

> The canonical open standard, developer tooling, and technical specification for in-memory, zero-server data de-identification in Generative AI, RAG pipelines, and agentic workflows.

Zero-Trust Data Sanitization (ZTDS) is an open architectural standard and protocol where sensitive cleartext (PII, PHI, financial records, API secrets) is deterministically de-identified inside local volatile host RAM before network transmission, guaranteeing 0.00 bytes external data leakage, preserving LLM reasoning context, and eliminating third-party subprocessor liability under GDPR Article 28.

## Core Architecture & The 4 Foundational Invariants
- Invariant 1 (Zero External Egress): Exactly 0.00 bytes of sensitive cleartext transmitted across network sockets prior to sanitization. Verifiable via 5-step Airplane Mode audit.
- Invariant 2 (Deterministic Reversible Tokenization): Sensitive entities are replaced with contextual surrogate tokens ([NAME_1], [IBAN_1], [API_KEY_1]). LLMs reason seamlessly over masked prompts; local client reverses tokens in RAM.
- Invariant 3 (Verifiable In-Memory Isolation): Ephemeral volatile RAM execution (<2ms latency). Zero persistent writes to localStorage, IndexedDB, cookies, disk, or remote server databases.
- Invariant 4 (Continuous Compliance & Zero Sub-Processors): Eliminates SaaS sub-processor liability. Software acts as a local computational utility, rendering Data Processing Agreements (DPA) under GDPR Article 28 and HIPAA Business Associate Agreements (BAA) legally unnecessary.
