Zero-Trust Security Architecture

End-to-end Encryption

All biometric data encrypted at source on the mobile device before transmission. AES-256 at rest, TLS 1.3 in transit.

Zero-Trust Service Mesh

No implicit trust between any services. Every inter-service call authenticated, authorized, and logged.

Immutable Audit Logs

Append-only forensic audit trail for every data access, AI inference, and state mutation. Cannot be deleted.

Rotating Credentials

All service credentials and API tokens have expiry and automatic rotation schedules. No static secrets.

Consent Management

Granular consent system. Users control exactly what data is stored, used for AI, and retained.

AI Engine Architecture

Multi-model Orchestration

Different AI models for vision, time-series analysis, anomaly detection, and natural language insight generation. No single model dependency.

Prompt Injection Defense

All user inputs sanitized before AI processing. AI outputs validated against safe-output schema before display.

Intelligence Quality Control

Every AI output scored for hallucination risk, architectural coherence, and factual reliability before delivery.

Explainability Layer

Every AI insight includes traceable reasoning. Users can see what data drove each observation.

Provider Abstraction

All AI providers wrapped in interface contracts. Any model can be swapped without platform rewrites.

System Laws (Constitutional Rules)

Non-negotiable architectural constraints. Every AI component, every engineer, every deployment must obey these unconditionally.

LAW-01 All logic communicates through the Intent Layer only — no direct mutations

LAW-02 No duplicated auth systems — single AuthService owns all sessions

LAW-03 No hardcoded secrets — all credentials in secure vault with rotation

LAW-04 No business logic inside UI components

LAW-05 All external APIs require typed validation before use

LAW-06 All async flows require error boundaries and graceful degradation

LAW-07 All state mutations must be traceable via audit log

LAW-08 No hidden side effects — every function has defined side-effect contract

LAW-09 No placeholder or simulated production logic in any release build

LAW-10 No new architecture patterns without explicit approval (context lock)

LAW-11 No AI output auto-executed without runtime validation

LAW-12 No direct provider SDK calls outside abstraction interfaces

LAW-13 Zero trust between ALL services — no implicit internal trust

LAW-14 All biometric data encrypted at source before leaving device

LAW-15 No diagnostic language in any consumer-facing AI output

LAW-16 All user data subject to consent before AI processing

Regulatory Evolution Roadmap

A phased path from consumer wellness to FDA-cleared diagnostics.

Phase 1

Now

2026–2027

Consumer Wellness

Launch as wellness observability platform. Consumer product positioning. No medical claims. FTC compliant language.

Phase 2

2027–2028

Research Partnerships

IRB-approved clinical research partnerships. Voluntary research mode. Build clinical evidence base.

Phase 3

Future

2028–2030

FDA 510(k) Pathway

Pursue predicate-based clearance for specific GI monitoring indications. Limited diagnostic claims.

Phase 4

Vision

2030+

Regulated Diagnostics

Full FDA-cleared diagnostic platform for specific indications, physician-prescribed, insurance reimbursable.
