The Trust Stack

6 instruments.
Not one product.

Six independent instruments that make AI systems auditable — from why the code exists to whether it actually worked. Rules as cited data. Deterministic decisions. Machine‑verified claims. Cryptographic attestation. Tamper‑evident outcomes.

Why it exists

Every question an auditor asks. One instrument per question.

AI systems are being deployed into regulated, high-stakes work faster than anyone can verify them. Isonomai is the architecture for the other direction: systems built to be examined.

Intent

Why does this exist?

Every non-obvious decision is recorded in a git-native ledger. The answer is quoted and cited — or the system says "not recorded." It never invents a reason.

Rules

What rule applies?

Legal and compliance rules are cited, versioned, dated data — never model memory. Every rule carries its source, its effective date, and its verification trail.

Decisions

Who decided — and can you rerun it?

Decisions are deterministic and human-gated. Every outcome reproduces exactly from pinned rule versions and inputs. AI suggests; an authorized human converts.

Claims

Can you prove that claim?

Any checkable claim — "tests pass," "the docs match the code," "this quote is real" — gets a verdict computed from executed evidence, never from model assertion.

Attestation

Who signed it?

Ed25519 signatures over canonical JSON, Merkle transparency logs, and offline public-key verification. You don't have to trust the operator — you can check.

Outcomes

Did it actually work?

An append-only, hash-chained, bitemporal ledger records what each system claimed and what actually happened — so calibration is measured, not asserted.

The doctrine

Four rules, enforced in code.

01

Fail closed

A claim that cannot be verified is UNVERIFIABLE — it is never silently accepted, and never downgraded to "refuted" without evidence. Missing anchors are flagged, not forgiven.

02

Humans hold the gate

AI output is typed Suggestion<T> and cannot reach a live action unreviewed. Real-world effects are dry-run by default and go live only with a logged, authorized token.

03 · The model is never the source
Not of a rule. Not of a why. Not of a verdict.
Models draft and search; sources, executions, and signatures decide. Anything the model asserts without evidence is treated as unwritten — the throughline beneath all four rules, enforced by type systems, triggers, and gates, not by policy documents.
04

Everything replays

Decisions reproduce exactly from pinned rule versions and inputs — no clock, no randomness, no hidden I/O. Ledgers verify offline from hashes and public keys alone.

For buyers

The instruments, packaged.

Three products built on the stack, each sold on its own — independent by design, one discipline. Maturity labels are honest: nothing below is purchasable until its gate clears.

Verdict

Proof that your AI behaves. Continuous adversarial testing — jailbreaks, prompt injection, PII leakage, drift — rolled into audit-grade evidence mapped to the EU AI Act, NIST AI RMF, and ISO 42001.

Regmap

Every AI system you run, mapped to the rules it answers to. An inventory and gap analysis: which regimes apply, what obligations follow, which required artifacts are missing — from a deterministic engine, not model memory.

The difference

Standard AI stops at plausible.
Isonomai goes further.

Verbatim anchoring

Quotes, amounts, dates, and citations must match their source character-for-character. A paraphrase is not evidence. An unanchored claim doesn't ship.

The machine ceiling

Models cannot self-certify. Machine audit takes a rule to "needs review" at best — promotion past that ceiling requires human attestation, on the record.

Offline verification

Hash chains, canonical JSON, and public keys mean a third party can verify the ledger with no access to our systems — and no trust in our word.

Diligence

Don't take our word for it.
That's the whole point.

The dossier covers every property: what's live, what's shipped, what's still in dry-run — with the receipts to check us.
