    Hiring & Screening — HR

    Hiring decisions that survive scrutiny months later.

    No Stamp → No Ship for high-impact HR decisions.

    Screening flags, adverse actions, and terminations are access, income, and reputation decisions. Defensibility needs both decision-time proof and current reliance state.

    • Gate high-impact actions by Status Link: not VALID → block or escalate (per programme runbooks)
    • Proof that travels outside your perimeter: counterparties verify scope • expiry • signer • status by link
    • Evidence Pack (IDA format) (decision-time snapshot): reusable across audits, tribunals, and partner reviews

    Why nowWhat's provenWho buysHow it worksProcurement clause

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

    Why HR buyers are moving now

    Governance expectations, dispute pressure, and vendor drift are converging.

    AI hiring governance expectations rising

    Regulators and oversight bodies increasingly expect traceability and controllability in AI-assisted employment decisions.

    Dispute, appeal, and tribunal pressure

    Adverse actions, screening rejects, and terminations are challenged months later. Evidence reconstruction costs escalate.

    Adverse-action workflow scrutiny

    Pre-adverse and final adverse action workflows are audited for timing, notice, and decisional defensibility.

    Model/vendor/policy drift risk

    Background check vendors, scoring thresholds, and policy templates change silently. Prior decisions stay trusted unless you revoke.

    Recourse and contestability expectations

    Candidates, employees, and oversight bodies expect decision outcomes to be checkable, challengeable, and correctable.

    Portable proof without exposing internals

    Counterparties need to verify status without access to HRIS, ATS, or internal case files.

    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)

    • Decision class + outcome (reject/hold/escalate; adverse action steps; employment action outcome)
    • Decision-time timestamp
    • Signer/authority reference
    • Scope boundaries + expiry
    • Validity state (VALID / NEEDS_REFRESH / WITHDRAWN / EXPIRED / NOT_VERIFIED)
    • Evidence window for dispute/review

    Does NOT prove

    • Underlying truth of candidate information
    • Outcome correctness
    • Certification / regulatory compliance
    • Candidate PII or HRIS internals by default

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

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

    Integration in 3 touchpoints

    Integration in 3 touchpoints

    1

    Issue

    At decision issuance (screening reject, adverse action, termination) → require a Stamp.

    2

    Notify

    In candidate notices / vendor packets / counsel bundles → include Status Link.

    3

    Rely

    At final action / access removal → verify Status Link (fail-closed).

    High-impact gating only. Everything else runs normally.

    Global Coverage

    Regulatory reality

    What teams are asked for in practice — no compliance claims.

    US flag

    US

    EEOC expectations, FCRA adverse-action workflows, and state/municipal automated employment decision tool rules.

    EU flag

    EU

    GDPR constraints on automated decision-making. Employment-related AI can fall into high-risk categories.

    UK flag

    UK

    ICO guidance on AI and data protection, Equality Act obligations, and employment tribunal expectations.

    Canada flag

    Canada

    Ontario AI-in-hiring disclosure requirement effective Jan 1, 2026. Signals tighter governance expectations.

    Australia flag

    Australia

    Privacy regulator guidance on AI products and personal information handling in employment contexts.

    APAC flag

    APAC

    Governance frameworks emphasise traceability and controllability. Singapore's agentic AI governance signals best-practice.

    Middle East flag

    Middle East

    Public-sector and employment-governance expectations around decision traceability and authority control.

    Africa flag

    Africa

    Scrutiny rising around administrative fairness, records, recourse, and privacy-aware handling of decision workflows.

    Good Proof doesn't certify compliance. It makes outputs verifiable, refreshable, withdrawable by link — so disputes don't collapse into "trust us."

    Jurisdictional Configuration

    Country overlays can be configured per programme

    Examples include programme-specific mapping for UAE, Saudi Arabia, South Africa, Kenya, Nigeria, and other jurisdictions where disclosure, retention, appeal handling, language support, and verifier-access requirements differ.

    Configure scope boundaries, evidence windows, redaction matrix, and verifier checklist per jurisdiction.

    Not legal advice. Final legal mapping is owned by programme counsel.

    Why now

    Governance expectations rising

    AI hiring governance and transparency expectations rising (audits, records, contestability).

    Dispute pressure increasing

    Litigation + dispute pressure increasing; evidence reconstruction costs explode.

    Silent drift risk

    Vendor/model/policy change creates silent drift unless you gate and revoke reliance.

    Good Proof doesn't decide outcomes; it makes governance verifiable at the moment it mattered — and reliance withdrawable when conditions change.

    Good Proof

    What gets stamped in this lane

    High-impact action classes (examples—define per programme):

    Screening & progression gates

    • Reject/hold/escalate outcomes driven by screening flags
    • Ranking cutoffs used to decide interviews (programme scoped)
    • Eligibility gates (right-to-work, minimum requirements, regulated role checks)

    Adverse action & background checks

    • Pre-adverse action trigger + workflow completion (programme scoped)
    • Final adverse action decision tied to report outcome
    • Dispute outcomes when a background report is challenged

    Employment actions

    • Termination / suspension / access removal decisions (programme scoped)
    • Policy breach classifications that trigger irreversible action
    • Probation failure decisions (programme scoped)

    Accommodations & exceptions

    • Accommodation approvals/denials (scope-bound, minimal disclosure)
    • Leave eligibility decisions (where duty-of-care liability applies)
    • Policy exception approvals with signer authority

    Vendor + model changes

    • Background check vendor / dataset changes affecting outcomes
    • Score threshold or screening logic updates
    • Model retrain / rule pack updates that alter behaviour

    What you get (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
    • Works in ATS/HRIS gates and ticket workflows
    IDA Evidence Pack

    IDA Evidence Pack (snapshot then)

    View full details →

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

    • Built for audits, tribunals, disputes, and procurement
    • Minimal disclosure by default (proof ≠ payloads)
    • Append-only history; withdrawal does not erase

    PDFs are great for filing. Status Links keep them current.

    Good Proof Logo

    Live Status States

    (what your systems can gate on)

    VALID

    Decision stands.

    Rely on it within scope.

    NEEDS REFRESH

    Policy/evidence changed.

    Re-verify before relying.

    WITHDRAWN

    Stop relying immediately.

    Returned wherever checked.

    NOT VERIFIED

    No proof exists.

    Block or escalate.

    VALID = valid within scope (not a guarantee of outcome correctness).

    When status changes — and what it means

    Status triggers define when a Status Link moves to NEEDS_REFRESH or WITHDRAWN. Understanding these ensures fail-closed enforcement at execution time.

    NEEDS_REFRESH triggers

    NEEDS_REFRESH

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

    Model retrain / rule pack update / threshold change

    scoring cutoffs, screening logic, risk label definitions

    Policy update

    adverse action workflow, templates, ban-the-box timing

    Background check vendor change or dataset refresh

    new provider, data source update, matching rule changes

    Job requirement change

    location, clearance, license, safety requirements

    Candidate dispute evidence received or correction event

    identity correction, right-to-work update (programme scoped)

    Approval authority changes

    who can sign what, and under which limits

    NEEDS_REFRESH means "re-verify before you rely," not "schedule a meeting."

    WITHDRAWN triggers

    WITHDRAWN

    Stop-rely signal. Execution must not proceed.

    Court, tribunal, ombuds, or oversight-directed pause for the affected decision class
    Confirmed configuration or policy-mapping defect with material impact on in-scope outcomes
    Integrity failure in upstream registry/feed relied on for issuance
    Authority boundary breach in delegated workflow (invalid signer or exceeded limits)
    Confirmed dependency compromise where current reliance can no longer be defended

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

    IDA Evidence Pack

    What's inside the IDA Evidence Pack

    Decision-time snapshot for disputes, audits, and filing.

    Decision summary + lane scope boundary
    Decision-time timestamp + evidence window
    Policy/criteria identifiers + version references
    Workflow/tool surface identifiers + version references
    Authority reference (signer/system)
    Verification transcript + timestamps
    Redaction matrix (what is intentionally excluded)

    Proof ≠ payloads. Raw CVs/PII/background reports are not required by default. Programme-gated access when required.

    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 and expiry window
    Signer authority reference (system or Guardian panel)
    Verification route and SLA

    Optional: tamper-evident anchoring to Good Proof LIVE Ledger for high-assurance programmes.

    Where budget comes from

    Usually funded from existing risk, legal, and compliance lines — not new category spend.

    Legal / dispute cost containment

    Trigger: Tribunal filing, adverse-action dispute, or settlement escalation

    Why it fits: Portable evidence + fail-closed reliance reduce reconstruction effort and dispute exposure.

    Audit / remediation readiness

    Trigger: Internal audit finding, regulator inquiry, or post-incident review

    Why it fits: Append-only verification history with Evidence Pack snapshots for review workflows.

    HR transformation / digital controls

    Trigger: New ATS/HRIS rollout, process change, or AI-tool adoption

    Why it fits: Lane-scoped integration at gate points; minimal validation footprint.

    AI governance / model risk controls

    Trigger: AI governance mandate, model retrain, or vendor-change risk assessment

    Why it fits: Material change triggers NEEDS_REFRESH; status controls model/vendor drift.

    Adverse-action workflow defensibility

    Trigger: FCRA/EEOC scrutiny, adverse-action timing audit, or candidate dispute spike

    Why it fits: Decision-time snapshot + live status make workflow checkpoints defensible.

    Incident response / stop-rely governance

    Trigger: Data breach, integrity failure, or vendor compromise affecting in-scope decisions

    Why it fits: WITHDRAWN propagates wherever Status Link is checked — no stale reliance.

    Start with one high-impact lane and prove dispute/audit 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: exception approvals, disputes, high-risk overrides, or post-incident outcomes with human liability.

    Mind Chill Guardians provide programme-scoped human finality for exception lanes only, minimizing sensitive payload handling, 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 audits, tribunals, procurement)
    Minimal disclosure by default (proof, not payloads)
    Add Guardian Desk to a Stamp SprintSee how escalation works

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

    How it works (simple)

    1

    Define the high-impact decision class

    Scope boundaries, evidence window, and what triggers refresh or withdrawal.

    2

    Require a Stamp

    No Stamp, NOT_VERIFIED, or NEEDS_REFRESH → block or escalate (per programme runbooks).

    3

    Ship portable proof

    Issue the Status Link and generate the Evidence Pack automatically.

    4

    Humans step in only when required

    Guardians handle exceptions and disputes inside defined scope, with anti-rubber-stamp controls.

    Procurement-ready clause

    Template language for your legal team.

    "For [High-Impact Decision Classes], Supplier shall issue a Good Proof Stamp prior to action. Buyer may verify status via the Status Link. Stamps returning NOT_VERIFIED, NEEDS_REFRESH, or WITHDRAWN shall block or escalate per programme runbooks."

    Schedule A: Status-Link Reliance Terms (HR)

    Definitions + operating rules procurement teams can copy/paste.

    1. Definitions

    • High-Impact Decision Class: A defined action category requiring verification (e.g., adverse action, termination, screening reject).
    • Status Link: The verification endpoint returning validity state + scope boundaries.
    • Evidence Window: Programme-defined period during which evidence is considered current.
    • Evidence Pack: Time-stamped snapshot for filing/disputes (IDA format).
    • Scope Boundary: Limits defining what the verification covers (and what it doesn't).

    2. Required states

    • 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 / stop-rely semantics

    • WITHDRAWN is returned wherever the Status Link is checked.
    • No execution may proceed on WITHDRAWN.
    • Optional: programme hooks/notifications for stop-rely distribution.

    SLA placeholders (complete per programme)
