    Hardware & Inference - Compute Integrity
    Protocols & Rails — Compute Integrity

    Integrity gates that stay authorised even after everything changes.

    No Stamp → No Ship for defined integrity-gated lanes.

    When AI drives gates in production, integrity is a liability surface. If reliability claims can't travel, procurement re-audits everything. Partners can't rely on your approval. Insurers can't underwrite on your word.

    • Stamp the operating envelope: thresholds, method, version, owner
    • NEEDS_REFRESH when any boundary changes (no silent drift)
    • WITHDRAWN when compromise or invalidation is declared (stop relying)
    • Counterparties verify without logging into your perimeter

    What's provenWhat gets stampedHow it worksProcurement clause

    Not a certification. Scope-limited verification. Acceptance depends on counterparty/programme requirements.

    Why compute integrity buyers are moving now

    Silent drift, stale approvals, and non-portable evidence are converging into procurement and liability risk.

    Drift detected, but counterparties still rely on stale approvals

    Runtime/hardware/driver updates silently change the integrity envelope. Prior approvals circulate without reflecting current state.

    Incident response lacks portable stop-rely proof

    When compromise or invalidation is declared, there is no machine-checkable way to propagate stop-rely across all relying parties.

    Procurement and audit rework from non-portable evidence

    Screenshots and internal dashboards don't travel. Every counterparty re-audits because they can't verify what was approved.

    Insurers require defensible reliance state

    Coverage and underwriting require evidence that travels outside your perimeter — not portal access or narrative summaries.

    External reviewers need verification without portal access

    Auditors, partners, and regulators need to check validity without VPN, NDA, or system integration.

    Version/method disputes consume engineering + legal time

    When method, threshold, or runtime version changes, proving what was authorised at decision time is manual archaeology.

    Good Proof provides scope-limited verification evidence and stop-rely semantics. It is not a certification.

    Good Proof

    What a Stamp proves (and what it doesn't)

    Proves (within lane scope)

    • Action class + outcome
    • Decision/execution timestamp
    • Signer/authority reference
    • Scope boundaries + expiry window
    • Validity state (VALID / NEEDS_REFRESH / WITHDRAWN / NOT_VERIFIED)
    • Evidence window for disputes/audit

    Does NOT prove

    • Reliability/performance correctness
    • Underlying model truth
    • Outcome accuracy or safety guarantee
    • Raw telemetry/logs/PII by default
    • Certification or regulatory compliance

    In disputes: Status Link = reliance state now. IDA Evidence Pack = fileable snapshot for decision-time record.

    Not a certification. Scope-limited verification. Acceptance depends on counterparty/programme requirements.

    Why this lane exists

    Integrity is a reliance boundary, not a dashboard. The risk is silent drift + stale approvals.

    Disputes are reliance disputes

    Not "what did metrics show?" but "what was authorised, under which method/version/thresholds, and is reliance still valid now?"

    Logs are not execution control

    Good Proof turns integrity gates into contract-referenceable controls: machine-checkable, scope-bound, expiry-aware, and revocable by link.

    Proof that travels

    If reliability claims can't travel, procurement re-audits everything. Partners can't rely on your approval.

    Reliability evidence vs permission to rely

    What reliability evidence portability gives

    • Reusable evidence context
    • Faster review handoffs
    • Lower repeat evidence collection

    What Good Proof adds

    • Execution-time authorisation gate
    • WITHDRAWN stop-rely propagation
    • Dispute-ready IDA snapshot

    Portable reliability evidence does not equal permission to rely.

    Execution and continued reliance require VALID Status Link in scope.

    Operating Envelope

    The compute integrity surface

    What must be defined and stamped before execution/reliance can proceed.

    Model artifact identifier/hash + version
    Inference runtime/engine version (framework/compiler/adapters)
    Hardware/accelerator class + firmware/driver/microcode boundary
    Precision/quantization/settings envelope
    Method/eval definition + threshold set + safety triggers
    Policy/rule pack identifiers + owner authority
    Environment scope (site/region/tenant/workload class)
    Evidence window + expiry

    Material surface change → NEEDS_REFRESH

    Compromise/invalidation/integrity failure → WITHDRAWN

    Good Proof

    What gets stamped

    Integrity-gated action classes (define per programme):

    Production

    • Promotion to production under defined envelope
    • Threshold/safety envelope overrides

    Operations

    • Safe-stop / throttle / rollback authorisations
    • Temporary exception approvals with expiry

    Incident

    • Incident closure outcomes + reliance restarts
    • Cross-hardware migration approvals

    Change

    • Runtime/driver/toolchain changes affecting integrity envelope
    • Red-team / eval outcomes that must remain current for reliance
    Integration in 3 touchpoints

    Integration in 3 touchpoints

    1

    Issue

    At envelope approval/change → require a Stamp.

    2

    Communicate

    Include Status Link in counterparty communications, runbooks, tickets, procurement packets.

    3

    Rely

    At integrity-gated execution/reliance → verify Status Link (fail-closed).

    High-impact gating only. Everything else runs normally.

    Live status + fail-closed enforcement

    VALID

    Proceed/rely within scope.

    NEEDS_REFRESH

    Re-verify before relying.

    WITHDRAWN

    Stop-rely immediately.

    NOT VERIFIED

    Unverified / fail-closed.

    If it's not VALID, the action does not execute.
    Fail-closed: unreachable verification returns NOT_VERIFIED.
    Block or escalate, never assume validity.
    VALID means valid within scope, not guaranteed correctness.

    When status changes — and what it means

    Status triggers define when a Status Link moves to NEEDS_REFRESH or WITHDRAWN.

    NEEDS_REFRESH triggers

    NEEDS_REFRESH

    When any of these occur, re-verify before you rely.

    Method/version definition changed
    Threshold or safety envelope updated
    Model retrain or capability boundary change affecting assumptions
    Runtime/engine/compiler/adapter change
    Hardware/driver/firmware/microcode change
    Data pipeline shift affecting integrity interpretation
    Policy/rule-pack update
    Evidence window expiry
    New deployment surface (region/site/hardware class)
    Related incident declares posture change requiring refresh

    NEEDS_REFRESH means "re-verify before you rely," not "defer."

    WITHDRAWN triggers

    WITHDRAWN

    Stop-rely signal. Execution must not proceed.

    Confirmed integrity breach or signing/key compromise
    Critical misconfiguration (wrong tenant/workspace/scope)
    Catastrophic drift/collapse requiring stop-rely
    Unauthorised boundary expansion detected
    Incident declares boundary untrustworthy pending investigation
    Regulatory/legal stop order

    Fail-closed: Wherever the Status Link is checked, if WITHDRAWN → block or escalate.

    How it works in integrity-gated execution

    1

    Stamp the operating envelope

    Method + thresholds + version + owner + expiry.

    2

    Gate integrity-relevant execution/reliance

    Pre-execution/pre-reliance Status Link check at defined high-impact gates.

    If not VALID → block or escalate. This is No Stamp → No Ship for integrity gates.

    3

    Revoke fast when risk changes

    Set WITHDRAWN on compromise/invalidation; stop-rely propagates wherever checked.

    Make the gate machine-checkable, not meeting-checkable.

    Example: integrity-gated inference

    1. Check Status Link for method + version + thresholds + owner

    VALID → execute

    NEEDS_REFRESH → re-verify envelope before execution

    WITHDRAWN / NOT_VERIFIED → block + incident path

    Two artefacts, one standard

    Status Link

    Status Link (authoritative now)

    A counterparty-verifiable link that returns current validity within scope.

    • Returns: status, scope, expiry, verified_at, signer, verify_url
    • Fail-closed: unreachable = NOT_VERIFIED
    • Built for contracts, runbooks, tickets, and automated gates
    IDA Evidence Pack

    IDA Evidence Pack (snapshot then)

    View full details →

    A time-stamped snapshot you can forward, file, and cite.

    • Append-only history; withdrawal ≠ erasure
    • Minimal disclosure by default; programme-gated access when required
    • Built for committees, audits, disputes, and procurement

    One Stamp produces both. PDFs are great for filing. Status Links keep them current.

    IDA Evidence Pack

    What's inside the IDA Evidence Pack

    Programme-configured. Minimal disclosure by default.

    Decision summary + lane scope boundary
    Decision-time timestamp + evidence window
    Method/version identifiers + threshold references
    Integrity envelope boundary definitions
    Signer/authority reference
    Verification transcript + timestamps
    Redaction matrix (what is intentionally excluded)

    Proof ≠ payloads. Raw telemetry/logs/PII are not required by default.

    What counterparties can verify

    What counterparties can verify

    No login. No portal. Just a link that fails closed.

    Live validity state: VALID / NEEDS_REFRESH / WITHDRAWN / NOT_VERIFIED
    Scope boundaries + thresholds + expiry window
    Signer authority reference (system or Guardian panel)
    verified_at timestamp
    Forwardable IDA Evidence Pack
    Optional signed verify responses (programme-scoped)
    Optional Good Proof LIVE Ledger anchoring (high-assurance programmes)

    Who uses this in Compute Integrity

    Buyers with high-impact integrity accountability and external reliance chains.

    Platform / ML Ops

    Pain: Silent drift breaks reliance — monitoring shows drift, but procurement and partners still rely on stale approvals.

    Outcome: Refresh triggers enforce re-approval. No silent drift allowed.

    Book a Compute Integrity Sprint

    Infrastructure / SRE / Runtime Engineering

    Pain: Hardware/driver/runtime changes invalidate integrity assumptions without notifying downstream reliers.

    Outcome: Material surface change triggers NEEDS_REFRESH; counterparties see updated state instantly.

    Book a Compute Integrity Sprint

    Security / Risk

    Pain: Integrity incidents create liability gaps — proving what was authorised at decision time is a scramble.

    Outcome: WITHDRAWN stops reliance fast. IDA snapshot is fileable for incident review.

    Book a Compute Integrity Sprint

    Procurement / Audit / Vendor Risk

    Pain: Proof doesn't travel — every counterparty re-audits because they can't verify what you approved.

    Outcome: Counterparty verification by link. Portable proof without portal access.

    Book a Compute Integrity Sprint

    Insurers / External Assessors

    Pain: Need defensible reliance story — coverage and underwriting require evidence that travels.

    Outcome: IDA snapshot is fileable/citable. Status Link is live and machine-checkable.

    Book a Compute Integrity Sprint

    Legal / Disputes / Incident Response

    Pain: Version/method disputes require proving what was authorised without handing over internal stack.

    Outcome: Scope-bounded verification with append-only history. Minimal disclosure by default.

    Book a Compute Integrity Sprint

    Enterprise Buyers / Regulated Customers

    Pain: Third-party reliance on compute integrity lacks portable, revocable evidence.

    Outcome: Status-linked verification with withdrawal propagation for regulated reliance chains.

    Where budget comes from

    Usually funded from existing risk and operations lines, not new category spend.

    Incident response + reliability engineering

    Trigger: Integrity breach, drift event, or post-incident reliance restart

    Why it fits: Portable stop-rely + reliance restart evidence reduces response time and cross-party coordination.

    Model risk governance / AI assurance

    Trigger: Model retrain, capability boundary change, or eval threshold update

    Why it fits: Scope-bounded verification makes method/version changes auditable and revocable.

    Third-party / vendor assurance

    Trigger: Counterparty audit, partner reliance review, or procurement challenge

    Why it fits: Counterparty-verifiable Status Link replaces repeated portal-access requests.

    Audit readiness and evidence operations

    Trigger: Regulatory review, internal audit programme, or inspection preparation

    Why it fits: Append-only Evidence Pack snapshots with redaction matrix for review workflows.

    Legal defensibility / dispute operations

    Trigger: Version/method dispute, liability challenge, or incident review

    Why it fits: Decision-time snapshot + live status make authorisation history defensible.

    Underwriting / insurance evidence

    Trigger: Coverage review, renewal, or incident-triggered underwriting reassessment

    Why it fits: Status-linked evidence travels to insurers without internal system exposure.

    Procurement friction reduction

    Trigger: Recurring re-audit requests, non-portable approval evidence, or supply chain scrutiny

    Why it fits: Portable verification reduces repeated audit cycles and evidence collection.

    Start with one integrity-gated lane and prove audit/procurement friction reduction before expansion.

    Mind Chill Guardians - A global network of diverse human reviewers
    A Global Human Layer
    Mind Chill Guardians
    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

    When Guardians are used (only when required)

    Most decisions remain automated. Humans step in only where human finality is required: disputed incident closures, high-risk overrides, contested withdrawals, or edge cases where liability lands on people.

    Mind Chill Guardians provide programme-scoped human finality for exception lanes only, with anti-rubber-stamp controls: conflict checks, rotation, sampling audits, and multi-review thresholds for high-risk lanes.

    From calming minds to defending outcomes

    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

    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.

    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

    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)

    Procurement-ready clause

    Template language for your legal team.

    "For any defined integrity-gated action, Provider shall maintain a Good Proof Stamp with an active Status Link. Actions taken with status NOT_VERIFIED, NEEDS_REFRESH, or WITHDRAWN shall be treated as unverified and must be blocked or escalated per programme rules."

    Schedule A: Status-Link Reliance Terms (Compute Integrity)

    Definitions + operating rules procurement teams can copy/paste.

    1. Definitions

    • High-Impact Decision Class: a decision type designated for Stamp gating (e.g., production promotion, envelope override, incident closure).
    • Status Link: the verification endpoint returning validity state + scope boundaries.
    • Evidence Window: the time period during which supporting materials are retained for review.
    • Evidence Pack: time-stamped snapshot for filing/disputes (IDA format).
    • Scope Boundary: the defined limits of what a Stamp covers (decision class, expiry, programme).

    2. Required States for Execution

    • VALID→ may proceed within scope.
    • NEEDS_REFRESH/ NOT_VERIFIED / WITHDRAWN → must block or escalate per lane rules.
    • Fail-closed:timeout/unreachable ⇒ NOT_VERIFIED.

    3. Withdrawal Semantics

    • WITHDRAWN is returned wherever the Status Link is checked.
    • No execution may proceed on WITHDRAWN.
    • History is append-only. Withdrawal does not erase.

    4. Technical Safeguards

    • HTTPS-only verifier endpoint.
    • Official verifier host allowlist.
    • Redirects forbidden.
    • Timeout/unreachable ⇒ NOT_VERIFIED.

    SLA placeholders (complete per programme)

    Verifier availability target: [___]%. Response-time target: [___] ms. Evidence Pack export: [___] hours. Status propagation: [___] seconds.

    5. Evidence Retention Defaults

    Retention period: [___] months/years. Jurisdictional overrides apply per programme counsel.
