WritersLogic Compliance Checkpoint

Master requirements matrix covering document provenance, authorship attestation, and regulatory compliance across 10 certification frameworks.

Last Updated: May 26, 2026|Next Review: August 31, 2026

Executive Summary

WritersLogic's architecture already addresses core requirements across multiple compliance domains. This checkpoint identifies what exists, what needs documentation, and what requires implementation.

Overall Readiness Score

Compliance readiness by domain showing current state and gap level
Domain	Current State	Gap Level
Cryptographic Integrity	Complete	Minimal
Authorship Attestation	Complete	Minimal
Timestamp/Provenance	Complete	Minimal
Audit Trail	Complete	Minor
Privacy by Design	Complete	Minimal
Identity Management	Partial	Moderate
Access Control	Partial	Moderate
Organizational Controls	Missing	Significant
Infrastructure Security	Missing	Significant

Key Finding: WritersLogic's technical architecture is exceptionally strong. The gaps are primarily in organizational/procedural controls required for enterprise certifications (SOC 2, ISO 27001, FedRAMP).

Appendix A: What WritersLogic Proves

Claims that WritersLogic can prove with corresponding basis and compliance alignment
Claim	Basis	Compliance Alignment
Content integrity	SHA-256 hash	All frameworks
Timeline ordering	Monotonic chain	C2PA, eIDAS
Existence before time T	External anchors	eIDAS, FRE 902
Human physical involvement	Biometric plausibility	Daubert, 21 CFR Part 11
Behavioral state at document state	Jitter anchor	Novel (exceeds standards)

Appendix B: What WritersLogic Does NOT Prove

Claims that WritersLogic does not prove with reasons and compliance impact
Claim	Reason	Compliance Impact
Identity of typist	No identity proofing	Requires IdP integration
Intent or cognitive origin	Out of scope	Acknowledged limitation
Exclusive authorship	Cannot detect collaboration	Acknowledged limitation
Absence of remote access	Out of scope	Acknowledged limitation

These limitations are explicit in every evidence packet -- this transparency strengthens legal defensibility.

Appendix C: Evidence Classes

Evidence classification system with meanings and legal implications
Class	Meaning	Legal Implication
A	Full integrity, biometrics verified	Highest evidentiary weight
B	Minor warnings	Strong evidence with noted limitations
C	Suspicious patterns	Requires additional corroboration
D	Invariant violated	Evidence compromised; limited weight
X	Verification failed	Not admissible without explanation

Appendix D: Challenger Requirements

To dispute WritersLogic evidence, a challenger must allege specific failures:

CED was falsified AND inconsistency went undetected
Hash chain was modified AND fork detection failed
Session key was compromised within declared lifecycle
External anchor was manipulated by Bitcoin miners or TSA
Biometric fingerprint was replicated without original data
Jitter anchor was forged without the destroyed seed

Generic doubt fails. Coordinated fabrication claims require extraordinary evidence.
