+# CAC Audit Playbook (Third-Party Executable)
+
+## 1. Objective
+
+Provide a repeatable procedure for external auditors to verify CAC compliance with no internal Summit access.
+
+## 2. Required Inputs
+
+- Attestation bundle directory containing:
+  - `cac.json`
+  - `cacert.json`
+  - `sbom.json`
+  - `provenance.json`
+- CAC issuer public key file (PEM/JWK).
+- Applicable policy profile (enterprise/regulatory baseline).
+
+## 3. Auditor Procedure
+
+1. **Intake validation**
+   - Confirm all four required files exist.
+   - Validate each file is valid UTF-8 JSON.
+2. **Schema and structural validation**
+   - Confirm mandatory fields in CAC and CACert.
+   - Confirm provenance includes deterministic digest over bundle.
+3. **Cryptographic verification**
+   - Verify CACert signature with provided public key.
+   - Recompute canonical digest for bundle and compare to recorded digest and `cacert.evidence_hash`.
+4. **Control verification**
+   - Apply control mappings in `docs/cac/control-mapping/*`.
+   - Validate risk-tier sampling obligations.
+5. **Sampling and traceability review**
+   - Sample at least 10 high-risk decisions or 5%, whichever is greater.
+   - For each sample, verify admissibility verdict, evidence references, and certificate linkage.
+6. **Issue classification**
+   - Missing artifact: Major non-conformity.
+   - Hash/signature mismatch: Critical non-conformity.
+   - Missing high-risk CACert: Critical non-conformity.
+
+## 4. Sampling Methodology
+
+- Population definition: all decisions marked `risk_level = high` in scope period.
+- Stratification: by decision type and business domain.
+- Minimum sample size: `max(10, ceil(population * 0.05))`.
+- Reproducibility: record random seed used for sample selection.
+
+## 5. Failure Conditions
+
+Audit fails if any of the following occur:
+
+- Required bundle artifact absent.
+- CACert signature invalid or unverifiable.
+- Deterministic digest mismatch.
+- Any sampled high-risk decision lacks CACert.
+- Control mapping evidence cannot be reproduced externally.
+
+## 6. Auditor Output
+
+Audit report MUST include:
+
+- Scope dates and sampled decision counts.
+- Control-by-control pass/fail matrix.
+- List of missing/invalid evidence with filenames.
+- Final compliance status: `COMPLIANT`, `CONDITIONALLY_COMPLIANT`, or `NON_COMPLIANT`.

+# CAC Reference Implementation Claim
+
+Summit is declared a reference implementation for CAC v1.0 by producing deterministic, portable, independently verifiable admissibility bundles and CACert outputs.
+
+## Reference Scope
+
+- Artifact generation: `packages/attestation/generator.ts`
+- Certification primitive: `packages/cacert/src/cacert.ts`
+- Audit verification CLI: `tools/cac-cli/index.mjs`
+
+## Test Vectors
+
+1. PASS verdict with zero policy failures.
+2. FAIL verdict with multiple policy failures.
+3. Missing artifact bundle (negative control).
+4. Hash mismatch between provenance and evidence files.
+
+## Compliance Validation Process
+
+1. Generate bundle deterministically from source artifacts.
+2. Verify bundle with `cac audit <bundle>`.
+3. Confirm control mapping alignment using documents under `docs/cac/control-mapping/`.
+4. Archive verification output with bundle for third-party review.

+## Conformance Claim Criteria
+
+An implementation MAY claim alignment when all mapped controls are evidenced in an externally reproducible bundle.

+## Independent Verification Notes
+
+- No private service calls are required.
+- Offline verification is supported using only bundle artifacts and public key material.
+- Any missing required artifact results in explicit control failure.

+## Auditor Assertion Template

+2. CACert was independently verifiable against published key material.
+3. Evidence bundle was deterministic and complete for sampled decisions.
+4. Exceptions were recorded as control failures, not omitted artifacts.

+# Enterprise Policy Template — Cognitive Admissibility Controls
+
+## 1. Policy Statement
+
+All decision-support and automated decision systems MUST produce admissible decision artifacts for each in-scope decision.
+
+## 2. Mandatory Requirements
+
+1. Systems MUST emit a CAC admissibility record (`cac.json`) for every high-risk decision.
+2. Systems MUST attach a verifiable CACert (`cacert.json`) for high-risk decisions before production action.
+3. Evidence bundles MUST be deterministic, portable, and independently verifiable.
+4. Missing or invalid CAC artifacts MUST trigger a deployment or execution block.
+
+## 3. Control Enforcement
+
+- Enforcing authority: Internal Risk + Compliance.
+- Technical enforcement: CI/CD gate plus periodic offline bundle audits.
+- Exception process: Time-bounded governed exception with documented risk owner approval.
+
+## 4. Audit Clause
+
+Business units MUST retain CAC evidence bundles and verification logs for no less than policy-defined retention periods (minimum 24 months).
+
+## 5. Non-Compliance Consequences
+
+- Immediate classification as policy breach.
+- Required corrective action plan within 10 business days.
+- Repeat violations escalate to executive risk committee.

+# Regulatory Language Draft — Cognitive Admissibility
+
+## Proposed Neutral Language
+
+1. Covered systems MUST produce admissible decision artifacts for materially impactful and high-risk decisions.
+2. Admissibility artifacts MUST include machine-verifiable evidence of policy evaluation outcomes.
+3. High-risk decisions MUST be accompanied by a cryptographically verifiable certificate of admissibility (CACert or equivalent).
+4. Regulated entities MUST maintain portable evidence bundles sufficient for independent third-party verification.
+5. Failure to produce verifiable admissibility evidence SHALL constitute a control deficiency.
+
+## Enforcement Clauses
+
+- Supervisory reviews MAY request randomly sampled admissibility bundles for independent verification.
+- Material discrepancies (signature failure, missing evidence, or hash mismatch) SHOULD be treated as significant control failures.
+- Persistent non-conformance MAY trigger corrective action directives, heightened reporting, or remediation mandates.
+
+## Implementation Neutrality
+
+This language is technology-neutral and does not require any specific vendor platform, runtime, or hosting environment.

+# CAC RFC Draft (Standards-Ready)
+
+## Abstract
+
+Cognitive Admissibility Certification (CAC) defines interoperable requirements for AI-assisted decision systems to emit verifiable admissibility outcomes and portable evidence bundles.
+
+## Normative Requirements
+
+- Implementations MUST emit deterministic admissibility artifacts.
+- Implementations MUST support independent verification of certificate signatures and evidence hashes.
+- High-risk decision pathways MUST require certificate-backed admissibility before action.
+
+## Interoperability
+
+Conforming implementations MUST expose artifacts as JSON and support offline verification with public key material.
+
+## Security Considerations
+
+Threats addressed include artifact tampering, unverifiable policy bypass, and unverifiable decision provenance.

+# CAC Governance Charter
+
+## Purpose
+
+Maintain an open, neutral, and auditable governance process for CAC evolution and conformance validation.
+
+## Principles
+
+- Neutrality: No vendor-specific dependencies in normative requirements.
+- Verifiability: All conformance claims must be reproducible from shared artifacts.
+- Reversibility: Certification and control decisions must support documented revocation.
+
+## Roles
+
+- Maintainers: curate specification and schema updates.
+- Auditors: independently validate implementation claims.
+- Implementers: generate conformant artifacts and maintain verification interfaces.
+
+## Change Management
+
+- Proposed changes published as public drafts.
+- Backward compatibility impact documented for each version.
+- Major changes require published migration guidance and test vectors.

+3. Deterministic hash algorithm declaration.
+4. No volatile timestamps inside signed evidence scope.
