The certification marks
What a conformance claim looks like, and what ends the right to make it
A certification mark is not a brand. It is a public assertion, backed by the Foundation's verification, that a specific implementation passed a specific version of the Conformance Test Corpus at a specific level. The mark's entire value rests on that assertion being checkable — which is why every grant, every re-certification, and every revocation is recorded in the program's public append-only ledger.
Three marks correspond to the Standard's three conformance levels. All are trademarks of The Sovereignty Foundation, currently the subject of pending applications — hence ™ throughout, not ®. No certification mark will be issued to any implementation before the Standard's v1.0 ratification.
The three marks
AGI COMPLIANT™
All CORE requirements verified; PROPOSED and FORWARD-LOOKING handling documented in the conformance report.
AGI CERTIFIED™
All CORE and PROPOSED requirements verified; FORWARD-LOOKING handling documented.
AGI CERTIFIED+™
Every requirement at every tier, including the Defense-in-Depth annex.
Usage rules
A mark attaches to an implementation, not an organization. "Acme Governance Engine v4 — AGI Certified™" is a well-formed claim; "Acme is AGI Certified" is not. The claim identifies the implementation, the level, and — in full form — the corpus version passed.
Claim only the level granted. A Compliant implementation does not describe itself as Certified. Levels are not cumulative marketing tiers; they are distinct verified states.
The claim expires with the certification. Lapsed re-certification, a MAJOR standard revision without re-certification inside the window, revocation under the thirty-day critical-vulnerability rule, or misuse of the mark each end the right to the claim. Reversion is recorded publicly.
Self-test results are not certification. Publishing sealed Phase-1 results is encouraged and citable as exactly what it is — "passes tc-agi-1 v0.1, self-tested, publicly disclosed" — but no mark attaches until the Foundation's independent verification and grant.
The reference implementation carries no mark. The Foundation does not certify itself; sovOS publishes its conformance evidence and its Known Deltas instead.
Mark display terms accompany the grant per Foundation licensing terms, published before any certification mark issuance.
The mark is checkable, or it is nothing.
Every grant has a ledger entry.
