Zero-defect processing pipeline · Immutable ledger · PIPL + HIPAA compliant
Built for PHI at scale. No consumer-grade shortcuts.

The Immutable Ledger

Three chains segregated by the logical orthogonality of the data types they contain. Every clinical event cryptographically timestamped. SHA3-256 hash chaining — retroactive modification mathematically impossible.

Chain 01
Clinical Record Chain

Every clinical event entering the platform creates a block. Lab result, imaging report, TCM diagnosis, prescription. SHA3-256 hash of source document plus structured extraction. Sole source of new records.

Records: 0
Chain 02
Longitudinal Chain

Links clinical records across time, providers, and borders. Every synthesis transaction references specific Clinical Record Chain blocks. Full causal traceability from current condition to earliest clinical event.

Syntheses: 0
Chain 03
Consent & Access Chain

Every access authorization, every query, every output delivery logged with requester identity, timestamp, and output hash. PIPL cross-border consent architecture. Access permission cannot create clinical records.

Clinical Intelligence Engine

Three-stage pipeline. Each stage has one responsibility. Zero defects.

01
Structured Extraction

Ingests Chinese-language medical records from any source — Ping An Good Doctor, WeChat Health, hospital portal exports, scanned records via OCR. Extracts standardized clinical markers with zero data loss. Unit normalization from Chinese to SI and US conventional. Medication name mapping from Chinese pharmacopeia to Western formulary. TCM records extracted into parallel schema alongside Western data.

02
Longitudinal Synthesis — DeepSeek AI

DeepSeek is the primary synthesis model. Native Chinese language capability. Self-hostable for PIPL compliance — PHI processed on China-side infrastructure without cross-border data transfer. Compiles records across all institutions into a single chronological timeline. Isolates conditions across TCM and Western diagnostic frameworks. Flags diagnostic gaps. Maps clinical findings to VA VASRD, SSA Blue Book, or specialist intake requirements at the specified target institution.

03
Output — Western Specialist Ready

Final output formatted to the intake requirements of the target institution — Mayo Clinic, Johns Hopkins, MD Anderson, Royal Marsden, or any specified center. Three output types: (1) Chronological narrative in English with US-standard units and formulary names. (2) FHIR R4-compliant JSON for direct EHR ingestion. (3) 3D clinical model blueprint — anatomical structural data for visualization, mirroring the diagnostic style of top Western institutions. All outputs hash-written to the Longitudinal Chain before delivery.

Technology Stack

Self-hosted. No Microsoft. PHI never leaves the jurisdiction without consent chain authorization.

AI Engine
DeepSeek — native Chinese, self-hostable, PIPL-compliant. Google Document AI for OCR. Google Translate (133 languages) for initial pass.
No Microsoft
Azure excluded. Office 365 excluded. PHI data sovereignty in China-market context requires self-hosted infrastructure.
Database
Supabase (PostgreSQL) — row-level security. Separate China-side and US-side instances. No cross-border data transfer without Consent Chain authorization.
Ledger
SHA3-256 three-chain immutable ledger. Clinical Record, Longitudinal, Consent chains. Block data replicated to both jurisdictions.
Encryption
AES-256 at rest · TLS 1.3 in transit · PHI stored encrypted · Ledger stores hashes only
Compliance
China PIPL · China DSL · HIPAA · HITECH · FedRAMP pathway available · Air-gap deployment for DOD/VA
API
Flask + Gunicorn · Nginx reverse proxy · REST endpoints for extraction, synthesis, audit export
Infrastructure
