High-impact actions should not change someone's life without a Good Proof Stamp.
Cryptography proves the receipt.Good Proof proves the reliance state.
Good Proof does not ask you to trust the AI. It gives your systems a live, external reliance check before the AI is allowed to act.

Founder's Note
Why we built Good Proof
High impact decisions do not stay internal.
They get challenged later by auditors, regulators, counterparties, and the public.
When liability lands on a person or institution, "the system decided" will not survive.
Good Proof turns "trust us" into "check it."
Authoritative now
A Status Link that updates when conditions change.
Fileable then
An IDA Evidence Pack for procurement and disputes.
Human when required
Mind Chill Guardians for edge cases.
"We built products used by millions, then watched 'trust us' fail when decisions were challenged."

The ProblemWhy automations fail in the real world
AI fails when workflows are vague and oversized. Good Proof breaks high-impact autonomy into defined decision classes.
01
Context
Scope boundaries. Evidence windows.
02
Logic
Refresh rules. Withdraw triggers.
03
Duty-of-care
Human finality when required.
Honest by design
What Good Proof does not claim
Good Proof does not claim an AI action is perfectly true, permanently safe, or impossible to manipulate. AI models change. Prompts drift. Tools fail. Context can be incomplete. Prompt injection can manipulate agents. Evidence can become stale. Good Proof exists because of that.
Verifiable
Cryptographically anchored. Independently checkable.
Scope-stated
Bound to a defined action class and programme scope.
Time-bound
Expiry-aware, refresh-aware, revocable on change.
Good Proof proves whether a high-impact action was authorised, scoped, evidenced, current, revocable, and safe enough to rely on at the point of consequence.
A Status Link you can actually rely on.
Most governance fails when proof needs to travel. A Good Proof Stamp gives you a single Status Link that survives:
Disputes
A defensible audit trail.
Procurement
Proof that travels outside your perimeter.
Agentic Security
Structural constraints beat prompts.
Stamp ID
A reference your contracts, tickets, and UIs can cite.
Status Link
The authoritative, auditable source of current validity within scope.
Refresh / Withdrawal
Append-only versioning. When conditions change, status changes—history remains.

How it works
Stamp → Status Link → Verify.That's the whole standard.
Define high-impact action classes
Hardship, eligibility, irreversible actions, overrides, high-value transfers. Material-change triggers + evidence windows.
Require a Stamp
No Stamp (or NOT VERIFIED / NEEDS REFRESH) → block or escalate. Fail-closed by design.
Counterparties verify by link
They check status + scope + expiry without needing your internal systems. Signed responses available.
Guardians step in when required
Edge cases, exceptions, disputes—scoped human finality with anti-rubber-stamp controls.
You don't buy another dashboard. You buy a contract-ready gate that makes high-impact autonomy shippable.

VALID

VALID = valid within scope under lane rules. Not a guarantee of outcome correctness.

Interoperability
Works with runtime accountability engines.
Works without them too.
Good Proof can run as your primary verification layer or ingest evidence from external runtime engines. We normalize evidence into procurement-ready reliance.
Common Evidence Schema
Normalized fields for status, scope, signer, evidence window, and trace references.
Adapter Interface
Integrate external engines through a stable adapter contract.
Conformance Tests
Verify consistency before relying on integrated evidence.
Portability and Customer Control
Exportable records and verifier portability reduce lock-in risk.
Federated Trust
Independent witnesses and quorum by risk lane
High-risk reliance should not depend on a single party. Good Proof supports independent witness models and quorum policies.
Independent Witnesses
Multiple verifiers can attest to the same evidence, removing single-party dependency.
Quorum by Risk Class
Higher-risk lanes can require multiple confirmations before reliance proceeds.
Conflict Handling
When witnesses disagree, escalation rules determine resolution path.
Tamper-Evident Event Trail
Every attestation, withdrawal, and status change is logged immutably.
Good Proof is scope-limited verification, not blanket certification.
Verify API
Verify Stamps at scale: status lookups, webhooks, access requests, signed responses (programme-scoped).

Why Mind Chill exists
AI is learning from clicks. Good Proof forces decisions to prove what they're based on, without dumping sensitive data.
AGI won't save us.
It knows what we click on, not what we care about.
Jamie, Mind Chill
Large models absorbed the open internet: genius and grief, but also scams, outrage, and performance. When the inputs get synthetic, the outputs don't just get wrong — they get confidently wrong.
What we do about it: scope-bound verification + fail-closed gates for high-impact actions.
Good Proof is the gate. Mind Chill is the human layer behind it: lived experience that makes the standard real.
One standard gate. Every sector.
High-impact action classes defined by lane. Material-change triggers + evidence windows.
Hardship / Duty of Care
Life-impact decisions with evidence windows
Irreversible Actions
Closures, bans, disconnects, denials—appealable by link
Insurance / Disputes
Evidence that survives hostile review
Incident Closure
Board / insurer / regulator scrutiny with audit trail
Procurement Claims
Vendor assurance without oversharing. Minimal disclosure.
Agent Permissions
Scope-bound authority. Short-lived. Revocable.

A Global Human Layer
Our Mind Chill Guardian Story
A global human layer that software can't fake.
When liability lands on a person, the sign-off should too.
Conflict-checked · Rotation-based · Audit-traceable · Programme-scoped
From calming minds to defending outcomes
Mind Chill began in 2017 as immersive art built to reduce anxiety and create calm at scale. Then the same feeds that buried calm and rewarded outrage started training the systems that now make real decisions. We didn't want more rhetoric. We wanted receipts.
The moment it clicked
A message arrived: someone's child felt safer because of what they experienced. Around the same time, lived experience inside our own community made one thing obvious: the nuance that matters in high-impact decisions can't be reliably reduced to a prompt. So we designed a human layer for the edge cases—structured, scope-bound, and auditable.
Guardians are not a "panel." They're a network.
Mind Chill Guardians come from different countries, backgrounds, and lived realities. That diversity is not branding—it's risk reduction. It makes decisions harder to game, easier to challenge, and more credible under scrutiny. Guardians do not "run the system." They review only what the lane requires humans to own.
Receipts over rhetoric
Operational Guardians plug into Good Proof lanes as a controlled finality mechanism: conflict checks, rotation, multi-review where required, and an audit trace tied to a Status Link. Minimal disclosure by default. If a decision is appealed months later, you can show what happened, within scope, without dumping sensitive payloads.
Why buyers choose Guardians
Lived experience at the edge cases (not a generic helpdesk)
Conflict-checked + rotation-based (anti-rubber-stamp by design)
Multi-review on high-risk lanes (when the programme requires it)
Audit-traceable outcomes (defensible in disputes, audits, procurement)
Minimal disclosure by default (proof, not payloads)
Not a certification. Scope-limited verification. Acceptance depends on counterparty/programme requirements.

Better AI Will Create Better Mistakes. That Is Good News for Good Proof.
Claude Opus 4.7 is not bad news for Good Proof. It is the market admitting the real problem has moved. Once models get good enough to act with confidence, the expensive part is no longer generating the answer. It is defending the outcome, handling the dispute, containing the blast radius, and avoiding weeks of rework when the machine was confidently wrong. That is where Good Proof starts.

The Boardroom Trap in AI Governance | Good Proof™
The EU AI Act is not a distant compliance story. Its staged rollout is already changing what boards need to know, prove, and control. By August 2026, the winners will not be the companies with the best AI principles slide. They will be the ones that can show evidence of control.

The EU DSA turned bans and restrictions into regulator-readable artifacts through Statements of Reasons and the DSA Transparency Database. That makes enforcement a proof problem: who authorised it, what was in scope, what was true then, and whether reliance should still stand today
