Executive Summary

This evidence document comprehensively details the implementation specifications, architectural decisions, workflow designs, and compliance controls for Track N: Legal & Regulatory Operations of the CODITECT Biosciences QMS Platform. As a regulated SaaS platform subject to FDA 21 CFR Part 11, HIPAA, GDPR, CCPA, and SOC 2 Type II requirements, the legal and regulatory operations infrastructure forms the foundation for market viability, customer trust, and ongoing regulatory compliance.

Track N encompasses five critical operational domains:

Terms of Service & Privacy Policy (N.1): Version-controlled legal document management with customer acceptance tracking and jurisdiction-specific variants
GDPR/CCPA Compliance Engine (N.2): Data Subject Request (DSR) processing, consent management, DPIA workflows, and cross-border data transfer controls
Contract Lifecycle Management (N.3): Template library, contract generation, BAA management, obligation monitoring, and compliance analytics
Regulatory Change Monitoring (N.4): Intelligence feeds, impact assessment workflows, FDA engagement coordination, and audit preparation automation
IP & Vendor Compliance (N.5): SBOM management, vendor risk assessment, open-source license compliance, supply chain security, and IP protection

This document serves as the single source of truth for legal and regulatory operations design, providing sufficient detail for implementation teams, compliance officers, legal counsel, and regulatory auditors to understand and validate the platform's legal compliance posture.

N.1: Terms of Service & Privacy Policy

Sprint: S5 | Priority: P0 | Depends On: None (legal drafting) Goal: Establish version-controlled legal document management with customer acceptance tracking and jurisdiction-specific variants

Regulatory Context: Terms of Service (ToS) and Privacy Policies are foundational legal agreements that define the contractual relationship between the platform and customers. For a regulated SaaS platform processing protected health information (PHI) and personal data:

GDPR Article 13/14: Requires transparent information about data processing activities
CCPA § 1798.115: Mandates disclosure of data collection, sharing, and sale practices
HIPAA § 164.502(e)(1): Requires written agreements (Business Associate Agreements) for PHI processing
FTC Act Section 5: Prohibits unfair or deceptive practices, including privacy policy violations
California B2B Privacy Law: Extends CCPA protections to business contact information

Design Principles:

Version Control: All legal documents must maintain complete version history with change tracking and effective date management
Transparency: Legal terms must be clear, accessible, and prominently disclosed at appropriate decision points
Consent Management: Material changes require re-acceptance with grace periods for existing customers
Jurisdiction Awareness: Terms must adapt to regional legal requirements (US, EU, UK, Canada, Australia)
Regulatory Integration: Legal documents must reference and incorporate regulatory obligations (FDA, HIPAA, GDPR)

N.1.1: Version-Controlled Legal Document System

Task ID: N.1.1 Objective: Design and implement a version-controlled legal document management system supporting ToS, Privacy Policy, Acceptable Use Policy (AUP), and Data Processing Agreements (DPA) with full change tracking, user acceptance workflow, and jurisdiction-specific variants.

Commit conventions:
- Message format: [DocumentType] [Jurisdiction] [Version] [ChangeType]: Summary
- Example: [ToS] [US_FEDERAL] [2.0.0] [MATERIAL]: Add AI-driven analytics disclosure per FTC guidelines
- Tags for versions: tos-us-federal-2.0.0
Diff generation:
- Use git diff with word-level highlighting for change visualization
- Store HTML-rendered diffs in DocumentChange.diffHtml for presentation
- Support side-by-side and unified diff views

Document Rendering Pipeline:

Markdown → HTML: Use Pandoc with legal document template (numbered sections, table of contents, definitions)
HTML → PDF: Use Playwright/Puppeteer for high-fidelity PDF generation with headers/footers, page numbers, and legal formatting
PDF Signing: Integrate with DocuSign/HelloSign for electronic execution of BAAs, DPAs, and custom terms

Change Tracking Workflow

Workflow States:

Draft: Legal team creates or updates document in feature branch
Legal Review: Internal legal counsel reviews for accuracy and completeness
Compliance Review: Compliance officer assesses regulatory alignment
DPO/General Counsel Approval: Final sign-off (required for material changes)
Scheduled for Publication: Document set to go live on effective date
Published: Document active and presented to new/existing customers
Superseded: Older version replaced by newer version (archived, not deleted)

Material Change Determination: Material changes (requiring re-acceptance) include:

New data collection or processing activities
Changes to data retention periods
New third-party data sharing arrangements
Changes to user rights or remedies
Modifications to limitation of liability clauses
Alterations to dispute resolution mechanisms
Addition of mandatory arbitration clauses
Changes to governing law or jurisdiction

Non-Material Changes (notification only):

Clarifications or formatting improvements
Corrections of typos or grammatical errors
Updates to contact information
Addition of explanatory examples
Reorganization of content without substantive change

Jurisdiction Variant Management

Variant Selection Logic:

Tenant Profile: Use Tenant.primaryJurisdiction field to determine default variant
User Location: Supplement with IP geolocation for visitor jurisdiction detection
Explicit Selection: Allow customers to select jurisdiction variant manually (stored in TenantSettings)
Hierarchy: More specific jurisdiction overrides general (US_CA overrides US_FEDERAL)

Variant Inheritance:

Base document (US_FEDERAL) serves as template
Jurisdiction-specific variants inherit base and override specific sections
Example: EU_GENERAL inherits US_FEDERAL but overrides:
- Data Subject Rights section (GDPR Articles 15-22)
- International Data Transfers section (GDPR Chapter V)
- DPO contact information section (GDPR Article 37)

Synchronization Protocol:

When base document updates, flag all variants for review
Legal team assesses whether base change impacts each variant
Variants updated independently and versioned separately
Prevent version drift alerts if variance exceeds 20% of base document

N.1.2: Legal Document Management Infrastructure

Task ID: N.1.2 Objective: Build legal document management infrastructure with markdown-to-PDF pipeline, version comparison tools, effective date management, and jurisdiction variant rendering.

Effective Date Management

Scheduled Publication:

Documents can be created with future effectiveDate

Cron job runs daily at midnight UTC to activate pending documents:

SELECT * FROM legal_documents
WHERE effective_date <= NOW()
AND expiration_date IS NULL
AND status = 'SCHEDULED';

Upon activation:
1. Set previous version's expirationDate to current effectiveDate
2. Update status from SCHEDULED to PUBLISHED
3. Trigger customer notification workflow (see N.1.3)

Grace Period Handling:

Material changes grant 30-day grace period for re-acceptance
During grace period, old version remains valid for existing customers
New customers must accept new version immediately
After grace period expiration, non-accepting customers flagged for account review

N.1.3: User Acceptance Tracking

Task ID: N.1.3 Objective: Implement comprehensive user acceptance tracking for legal documents, including ToS acceptance per version, re-acceptance on material changes, acceptance audit trail with IP/device evidence, and grace period enforcement.

N.2: GDPR/CCPA Compliance Engine

Sprint: S6-S7 | Priority: P0 | Depends On: C.1 (Data Infrastructure), D.3 (HIPAA Security Controls) Goal: Implement comprehensive GDPR and CCPA compliance engine supporting Data Subject Requests (DSR), consent management, Data Protection Impact Assessments (DPIA), cross-border data transfer controls, and Data Processing Agreement (DPA) automation.

Regulatory Context:

GDPR (EU): General Data Protection Regulation — rights of access, rectification, erasure, restriction, portability, objection
CCPA/CPRA (California): California Consumer Privacy Act / Rights Act — rights to know, delete, opt-out, correct
UK GDPR: Substantially similar to EU GDPR with minor UK-specific variations
Other US State Laws: VCDPA (Virginia), CPA (Colorado), CTDPA (Connecticut), UCPA (Utah) — follow similar patterns

Data Subject Rights Summary:

Right	GDPR	CCPA	Response Time	Scope
Right of Access	Art. 15	§ 1798.100	30 days (GDPR), 45 days (CCPA)	All personal data held
Right to Rectification	Art. 16	§ 1798.106	30 days, 45 days	Correct inaccurate data
Right to Erasure ("Right to be Forgotten")	Art. 17	§ 1798.105	30 days, 45 days	Delete data (with exceptions)
Right to Restriction	Art. 18	N/A	30 days	Temporarily limit processing
Right to Portability	Art. 20	N/A	30 days	Receive data in structured format
Right to Object	Art. 21	N/A	30 days	Object to specific processing
Opt-Out of Sale/Sharing	N/A	§ 1798.120	15 days	Stop selling/sharing data

Compliance Requirements:

Identity Verification: Must verify requestor identity before fulfilling DSR (2-factor minimum)
Free of Charge: DSR fulfillment must be free (unless manifestly unfounded/excessive)
Response Format: Data must be provided in structured, commonly used, machine-readable format
Exceptions: Certain data must be retained for legal/regulatory compliance (FDA, SOC 2, HIPAA)
Audit Trail: All DSR processing must be logged for regulatory audit

N.2.1: Data Subject Request (DSR) Processing

Task ID: N.2.1 Objective: Build comprehensive Data Subject Request processing engine supporting all GDPR/CCPA rights with automated data discovery, compilation, verification, and fulfillment workflows.

N.2.3: Data Protection Impact Assessment (DPIA)

Task ID: N.2.3 Objective: Create Data Protection Impact Assessment (DPIA) workflow with templates, risk scoring, DPO review process, remediation tracking, and documentation per GDPR Article 35.

A DPIA is required when processing is likely to result in high risk, including:

Systematic and extensive evaluation (e.g., profiling, automated decision-making)
Large-scale processing of special categories (e.g., health data, genetic data)
Systematic monitoring of publicly accessible areas (e.g., video surveillance)
New technologies (e.g., AI/ML models, biometric authentication)
Processing that prevents data subjects from exercising a right (e.g., access restrictions)

For Bio-QMS platform, DPIAs are triggered by:

Processing PHI (HIPAA covered entities)
AI-driven agent decision-making
Cross-border data transfers (EU → US)
New third-party integrations
Major feature releases affecting data processing
