Margelis Trust Layer

AI-era trust infrastructure for business

Signed agents, evidence passports, claim-control, audit trails and timestamp-ready proof packages for organizations operating with AI, disputed digital files and automated decisions.

Margelis builds trust infrastructure for AI-era business: signed agents, evidence passports, claim-control, audit trails and qualified timestamp-ready proof packages.

What we do not do: we do not prove that a photo is real or that an event happened, and we are not a forensic, detection, or court-admissibility guarantee. We document the technical evidence state, enforce claim-control, and prevent unsupported authenticity claims from becoming strong professional conclusions. Admissibility is always the court's decision.

Modules — what is available, what is on the roadmap

We apply our own claim-control to ourselves: only the modules marked available ship today.

Module	What it does	Status
Vestigium Evidence Passport	Disputed-file intake; hash manifest; technical evidence state; signed PDF/JSON dossier; verify & review.	available
CAAD claim-control	Anti-overclaim control — deterministically downgrades, blocks, or requires review when evidence does not support a stronger claim. Not an "AI reviewer".	available
Sigillum	Internal integrity & accountability seal — signs the Evidence Passport and the CAAD audit decision; supports the verify flow.	available
Risk Intelligence	AI & business risk exposure as a single, board-actionable number. See Risk Intelligence →	available
Regulatory Change Radar	Detects regulatory drift, maps it to your obligations, and seals each alert into a signed, tamper-evident chain anyone can verify over HTTP. See the Radar → · live verify.	available
Timestamp layer	Non-qualified RFC 3161 timestamp today. Qualified eIDAS timestamp (QTSP) is the next professional trust layer — not yet integrated.	partial
Agent Mandate Certificate	Who an AI agent is, what it may and may not do, and who is responsible.	roadmap
Agent Action Evidence Passport	What an agent did, under what mandate, with what evidence, and what a human approved.	roadmap
Living Certificate	Ongoing trust status — revocation, mandate validity, evidence updates.	roadmap
AI Act Evidence Pack	Article 4 literacy and Article 50 transparency evidence; internal AI-governance dossier.	roadmap

Who it is for

Primary	fraud & compliance, fintech, insurance, business risk, platform trust & safety, AI-agent companies, regulated SMEs using AI.
Secondary	litigation / IP / reputation lawyers, professional review, expert consultants.

How the layers fit

SHA-256	locks file / manifest identity
CAAD	prevents false success — downgrade / block / review
Sigillum	signs our decision (internal integrity seal)
QTSP timestamp	external qualified time (roadmap; freeTSA non-qualified now)

Even a qualified timestamp proves only that a hash existed at a time — not that the content is authentic or that an event happened. That boundary is held by CAAD + signed limitations.
