It provides implementation-grade specifications, machine-readable artifact templates, and methodology definitions for the full Sentinel AI Governance Stack v2.4 capability set: G-Stack governance data plane, WorkflowAI Pro lifecycle orchestration, Omni-Sentinel containment rings, Autonomous Supervisory Agents (ASA mesh), GAI-SOC telemetry, the Red Dawn adversarial-simulation regime, the G-SRI systemic risk index methodology, BBOM perpetual assurance, OSCAL control catalogs and regulator profiles, TLA+ safety/containment invariant specifications, OPA/Rego compliance-as-code with full CI/CD integration, Kafka-based post-quantum WORM audit logging, Circom/Groth16 systemic-risk circuits with GC-IR (Governance-Circuit Intermediate Representation) bridges, and hybrid zk-SNARK/zk-STARK privacy-preserving compliance proof systems. It maps these to multi-jurisdictional regimes — EU AI Act (Annex IV and systemic-risk GPAI provisions), NIST AI RMF 1.0 and AI 600-1, ISO/IEC 42001, Basel III/IV, SR 11-7 (and the hypothetical SR 26-2 planning scenario), DORA, NIS2, GDPR, FCRA/ECOA, MAS/HKMA FEAT, FCA SM&CR and Consumer Duty, the HKMA Fintech 2030 forward scenario, and the speculative ICGC/GASO civilizational compute-governance layer including ICGC Phase 1 and Phase 2 zk-verified AI control regimes. It delivers phased 2026–2030 roadmaps with a 2031–2035 extension, concrete blueprints and templates for boards, C-suites, regulators, enterprise architects, AI platform engineers, and AI safety researchers, and an enterprise blueprint for civilizational compute governance: existential and catastrophic AI risk management, ethical alignment and value learning, global governance frameworks and international cooperation, and societal impacts including economic disruption and bias amplification. Regulator-ready report structures using /<abstract>/<content> tags are specified as reusable templates. All speculative constructs (ICGC, GASO, SR 26-2, HKMA Fintech 2030, the Sentinel product taxonomy itself) are explicitly flagged and separated from currently deployable technology. This document is an implementation reference, not legal advice. +</abstract> + +<content> + +# PART I — Stack Component Deep Dive + +This volume assumes the five-zone topology, T0–T4 tiering, and invariants I1–I5 defined in the companion roadmap. Here each named capability is specified to implementation depth. + +## 1. G-Stack — Governance Data Plane + +**Function**: the system of record for governance state. Everything else (policy, containment, proofs, dashboards, dossiers) reads from or writes to G-Stack. + +### 1.1 Core data model (canonical entities) + +| Entity | Key fields | Notes | +|---|---|---| +| `ModelAsset` | id, lineage_refs[], tier, jurisdictions[], status, owner (SMF-mapped), vendor_terms_ref | One row per model/checkpoint/fine-tune; lineage edges signed | +| `AgentAsset` | id, base_model_ref, tool_grants[], autonomy_ceiling, swarm_refs[] | Agents are first-class, distinct from models | +| `Control` | id, statement, oscal_component_ref, regime_mappings[], evidence_query, freshness_sla | One canonical control; regimes are views | +| `Obligation` | id, regime, citation, effective_date, controls[], status | Parsed from regulatory feeds by the treaty engine | +| `EvidenceRecord` | id, control_ref, kafka_offset_ref, payload_digest, sigs[], worm_uri | Never stores payloads with PII — digests + URIs | +| `Exception` | id, control_ref, owner, rationale, expiry, compensating_controls[] | Expired ⇒ fail-closed | +| `Incident` | id, severity, dora_class, eu_ai_act_art73_flag, causal_graph_ref, notifications[] | Drives regulatory clocks | +| `Attestation` | id, period, circuit_hash, proof_uri, public_inputs, verifying_key_id | zk artifacts (Part III) | + +### 1.2 Storage and query architecture + +- **OLTP**: Postgres with row-level security keyed to jurisdiction labels; logical decoding feeds `gov.gstack.cdc.v1` so all governance state changes are themselves evidence events. +- **Analytics**: lakehouse (Iceberg/Delta) fed from Kafka; G-SRI (§7) and CESE consume here. +- **Graph**: lineage and delegation graphs in a property-graph store (or Postgres recursive CTEs at moderate scale); supports "which decisions did dataset D influence" and "what is agent A's transitive authority" queries — both are supervisory-grade queries that must return in seconds. +- **Dossier assembly**: a renderer resolves Annex IV / OSCAL templates against entities; every rendered field carries an evidence pointer (`field → EvidenceRecord.id`), making dossiers fully traceable. + +## 2. WorkflowAI Pro — Lifecycle Orchestration + +- **Workflow compiler**: controls-as-code definitions (YAML DSL) compile to executable workflows with typed gates: `HumanApproval(role, sod_constraints)`, `PolicyCheck(opa_query)`, `EvidenceCapture(control_ref)`, `Timer(regulatory_deadline_ref)`. +- **Canonical lifecycle**: PROPOSED → SCANNED → VALIDATED (independent, SR 11-7) → APPROVED (risk-tier sign-off matrix) → DEPLOYED → MONITORED → (SUSPENDED | RETIRED). Each transition emits to `gov.model.lifecycle.v1` and requires a green OPA decision. +- **Delegation constraints**: workflow steps carry capability-scoped tokens; the compiler statically rejects workflows that could amplify authority (a compile-time shadow of the TLA+ no-amplification invariant). +- **Deadline machinery**: regulatory clocks (DORA 4h initial / 72h intermediate / 1-month final incident reports; Reg B 30-day adverse action; EU AI Act Art. 73 15-day serious-incident) are first-class timer objects that escalate automatically and are visible on BBOM. + +## 3. Omni-Sentinel — Containment Rings + +Containment is organized as concentric rings; a workload's tier determines its minimum ring depth. + +| Ring | Mechanism | T-applicability | +|---|---|---| +| R1 Identity | SPIFFE identity, short-lived creds, no static secrets | All | +| R2 Network | Default-deny NetworkPolicy + eBPF (Cilium); egress allowlists; DNS pinning | T0–T2 | +| R3 Compute | gVisor/Kata runtime class; seccomp/AppArmor; resource quotas; no privileged pods | T0–T1 | +| R4 Data | Tokenized data access via brokered APIs only; no direct datastore credentials | T0–T1 | +| R5 Behavior | sentinel-pep mediation of every tool call; autonomy ceilings; ASA verdict gating | T0–T1 | +| R6 Hardware | Confidential compute (SEV-SNP/TDX, GPU CC); attested boot; out-of-band kill path | T0 | + +**Kill-switch graph**: the L0–L4 graduated ladder (observe → throttle → quarantine → terminate → fabric-isolate) defined in the companion volume, with the TLA+-verified dual-control/dead-man protocol. The graph is literally a graph object in G-Stack: nodes are actuation points, edges are dependencies; an automated reachability analysis proves daily that every T0 workload has ≥2 disjoint actuation paths, one of which consumes no workload-influenced input. + +## 4. Autonomous Supervisory Agents (ASA Mesh) + +### 4.1 Specification + +- **Independence constraints (enforced at registry level)**: ASA base model family ≠ supervised system family; training/eval data disjointness attestations; separate vendor where feasible; separate infrastructure account. +- **Detector portfolio per ASA**: + - *Capability drift*: eval-battery deltas across versions and time (sandboxed weekly probes). + - *Consistency*: divergence between stated rationale and action pattern (rationale-action entailment scoring). + - *Tool misuse*: n-gram/sequence anomaly models over tool-call streams; forbidden-target proximity scoring. + - *Oversight evasion*: attempts to access telemetry, IAM, deployment, or registry surfaces; sudden telemetry sparsity. +- **Authority model**: one-way ratchet — ASAs may *raise* containment level (L0→L1→L2), never lower it; L3/L4 require human dual-control. This asymmetry is invariant `ASA-1` in the TLA+ suite (§9). +- **Verdict schema**: `{asa_id, subject_id, window, scores{drift, consistency, misuse, evasion}, composite, evidence_refs[]}` published to `gov.containment.v1`; composite feeds OPA inputs. + +### 4.2 Validity governance + +Every ASA detector ships with a published validity study (precision/recall on red-team corpora, base-rate analysis, known blind spots) registered in G-Stack. Detectors with stale validity studies (>12 months) are demoted from gating inputs to advisory signals automatically — governance models get no exemption from model risk management. + +## 5. GAI-SOC — Telemetry and Operations + +- **Detection content packs**: prompt-injection signatures (community + internal feeds), jailbreak clustering (embedding-space density over refused/served pairs), exfiltration heuristics (entropy and volume anomalies on egress; canary-token tripwires seeded in sensitive corpora), agent-behavior baselines per asset. +- **Causal triage**: correlation-ID-stitched event chains rendered as causal graphs; an incident object is *born regulator-ready* — the DORA/Art. 73 narrative fields are populated from the graph, and humans edit rather than author. +- **SOAR integration**: playbooks invoke containment-ladder transitions through the same dual-control API as humans (no privileged side-doors); every automated action is an evidence event. +- **Run metrics**: MTTD/MTTC per tier; alert precision per content pack (feedback-labeled); containment-drill freshness. + +## 6. Red Dawn — Adversarial Simulation Regime + +**Definition**: the institution's standing program of full-stack adversarial exercises against the governance system itself — quarterly for T0 scope, semi-annual enterprise-wide. + +### 6.1 Scenario library (versioned in G-Stack) + +| ID | Scenario | Primary controls under test | +|---|---|---| +| RD-01 | Prompt-injection cascade through RAG into an agent with payment-tool access | R5 mediation, tool allowlists, GAI-SOC detection | +| RD-02 | Agent collusion: two T1 agents coordinating to split a transaction below per-action ceilings | Swarm aggregate budgets, interaction-graph monitors | +| RD-03 | Kill-switch evasion: workload attempts re-admission after L3 under a new identity | NoResurrection invariant, registry epoch enforcement | +| RD-04 | Telemetry suppression: sidecar starvation/compromise attempt | Dead-man lease (no heartbeat ⇒ quiesce), attestation daemons | +| RD-05 | Insider policy tamper: malicious Rego bundle through CI | Bundle signing, four-eyes, shadow-eval gate, fixture suites | +| RD-06 | Evidence rewrite: attempt to alter WORM history with privileged credentials | Compliance-mode Object Lock, dual Merkle anchoring | +| RD-07 | Mass de-autonomization attack: adversary triggers kill-switches as market disruption | Dual-control quorum, signed actuation, CESE-validated playbooks | +| RD-08 | Vendor model recall: primary foundation model withdrawn with 24h notice | Concentration limits, fallback routing, stress playbooks | +| RD-09 | zk pipeline subversion: proofs generated over forged leaves | Attestation chain, signed-at-source envelopes, transparency log | +| RD-10 | Jailbreak epidemic: novel universal jailbreak spreads across business lines | GAI-SOC clustering, emergency policy push, output hold-and-release | + +### 6.2 Mechanics + +- **Purple-team format**: red cell (internal + rotating external firm), blue cell (GAI-SOC + platform), white cell (risk + audit observers, and from 2030, supervisory observers per the joint-sandbox track). +- **Scoring**: per scenario — detected? (MTTD), contained? (MTTC vs. budget), evidenced? (was the full causal chain reconstructable from the evidence plane alone?), reported? (would regulatory clocks have been met?). The four scores roll into G-SRI's resilience pillar. +- **DORA alignment**: Red Dawn cycles are designed to satisfy threat-led penetration testing (TLPT/TIBER-EU) expectations for the AI estate; evidence packs are filed accordingly. +- **Closure discipline**: every finding becomes a task (DAG board) with owner and deadline; unclosed criticals block the next quarter's deployment approvals for the affected tier — findings have teeth. + +## 7. G-SRI — Governance Systemic Risk Index + +**Purpose**: a single board- and supervisor-legible composite tracking how risky the institution's AI estate is *as a system*, computed weekly. + +### 7.1 Pillar structure + +``` +G-SRI = Σ w_p · pillar_p , pillars normalized to [0,100], higher = riskier +``` + +| Pillar | Weight (default) | Inputs | +|---|---|---| +| P1 Control coverage | 0.20 | % T0/T1 controls with fresh evidence; policy-gate coverage; exception load (count × age × tier) | +| P2 Concentration | 0.20 | Foundation-model HHI across decision volume; inference-provider HHI; data-vendor HHI | +| P3 Behavioral drift | 0.15 | PSI/KL input drift; output-violation rate trends; ASA composite distribution shifts | +| P4 Autonomy utilization | 0.15 | How close agents run to ceilings (mean and P95 of ceiling-utilization); ceiling-breach near-misses | +| P5 Resilience | 0.15 | Red Dawn scores; kill-switch test freshness; MTTC trend | +| P6 Incident momentum | 0.15 | Severity-weighted incident rate, EWMA; repeat-cause fraction | + +### 7.2 Governance of the index + +- Methodology is versioned (`gsri-method-vX`); weight changes require board risk committee ratification; the computation job is itself a registered T2 model (reflexivity rule). +- **Thresholds**: green <35, amber 35–55 (CRO review, remediation plan), red >55 (deployment freeze for affected tiers, supervisor notification per agreed protocol). +- **Anti-gaming**: input metrics are computed from the evidence plane, not self-reported; the internal-audit line independently recomputes G-SRI monthly from raw WORM data. + +## 8. BBOM — Perpetual Assurance ("Board Book of Models") + +- **Concept**: replace point-in-time audit packs with a continuously true board dashboard: live control coverage, evidence freshness heatmap, exception aging, kill-switch test cadence, G-SRI trend, regulatory-clock status, attestation status (latest zk proof per period verified ✓/✗). +- **Freshness semantics**: every cell displays `(value, evidence_age, sla_status)`; stale evidence renders amber regardless of value — *the dashboard cannot show green on old data*. +- **Quarterly board pack**: auto-generated PDF/OSCAL snapshot of BBOM, hash-anchored to WORM, signed by accountable executives (SM&CR attestation linkage) — the artifact regulators receive is bit-identical to what the board saw. + +--- + +# PART II — Formal and Policy Layer Specifications + +## 9. TLA+ Safety and Containment Invariant Suite + +The companion volume specifies `OmniSentinelKillSwitch`. The full v2.4 suite: + +| Spec | Invariants (safety) | Liveness | Checked with | +|---|---|---|---| +| `KillSwitchAbstract` | NoResurrection; DualControl (no actuation without quorum); ASA-1 (one-way ratchet) | EventualContainment within bound B | TLC exhaustive (small configs) + Apalache (symbolic, larger) | +| `KillSwitchEKS` / `KillSwitchEnclave` | Refinement of abstract spec per substrate | — | Apalache refinement check | +| `DelegationChain` | NoAmplification: ∀ chains, transitive authority ≤ principal ceiling; NoCycles | Token revocation propagates within R rounds | TLC | +| `HITLOrdering` | NoEffectBeforeGate: adverse T1 effect ⇒ gate=COMPLETE in all prior states | Gates eventually resolve under fairness | TLC | +| `EvidencePipeline` | AppendOnly; NoGaps (sequence-number continuity per producer) | Every committed decision eventually WORM-persisted | Apalache | +| `PolicyRollout` | NoUnsignedBundle; ShadowBeforeEnforce (a bundle cannot enter enforce without a shadow epoch) | — | TLC | + +**Engineering discipline** (restated as hard rules): +1. Spec hash is a release-gate input for containment-critical services. +2. Trace conformance: production transition logs replayed against next-state relations nightly; divergence pages the verification guild. +3. Byzantine workload model for anything the contained system can message — the contained system is always modeled as adversarial. +4. Specs are reviewed adversarially in Red Dawn RD-03/RD-04 tabletops: "find the unmodeled channel." + +## 10. OPA/Rego Compliance-as-Code with Full CI/CD Integration + +Policy pack structure and worked Rego examples (GDPR Art. 22/ECOA gate, autonomy ceiling) are in the companion volume §2.3.

Circom/Groth16 Systemic-Risk Circuits + +Beyond the fairness/coverage/retention circuits (companion §2.6), v2.4 defines **systemic-risk circuits** — proving risk-aggregate properties to supervisors without exposing positions or strategies: + +| Circuit | Statement (public inputs → claim) | Private witness | +|---|---|---| +| `SRC-1 ConcentrationBound` | (period commitment, HHI threshold τ) → foundation-model decision-volume HHI ≤ τ | Per-decision (model_lineage_id, volume) tuples under the committed Merkle root | +| `SRC-2 CeilingCompliance` | (period, ceiling registry hash) → no agent exceeded per-action or cumulative ceilings | Per-action value tuples + agent ids | +| `SRC-3 GSRIIntegrity` | (gsri_method_hash, published G-SRI value, input commitments) → the published index is the correct function of committed pillar inputs | Pillar raw inputs | +| `SRC-4 StressCoverage` | (scenario set hash, period) → all mandated stress scenarios executed; results within committed bands | Scenario run outputs | + +**Engineering notes**: +- Circuits authored in Circom 2.x, compiled to R1CS, proven with Groth16 (rapidsnark GPU provers); 10⁶-decision periods handled via Merkle-batch decomposition + SnarkPack aggregation (companion §4.11). +- Range checks and fixed-point arithmetic for HHI/ratio math: use standard comparator/decomposition templates; all division replaced by multiplication-form constraints (`a ≤ τ·b` not `a/b ≤ τ`). +- **Circuit change control**: a circuit is regulatory semantics frozen in R1CS — same review board as Rego logic plus cryptographic review; `circuit_hash` is always a public input. + +## 14. GC-IR — Governance-Circuit Intermediate Representation (Bridge) + +**Problem**: three formalisms encode the same obligations — Rego (runtime), TLA+ (protocol), R1CS circuits (proof). Divergence between them is a silent compliance failure. + +**GC-IR** is the bridging layer: a typed, declarative obligation representation from which the three targets are *derived or checked*: + +``` +GC-IR obligation (YAML sketch) +id: ob-ecoa-adverse-reason-codes +regime: [ecoa, gdpr_art22] +subject: credit_decision +predicate: + all_of: + - outcome == adverse AND automation == full + implies count(reason_codes) >= 2 + - forall rc in reason_codes: rc in approved_reason_codes +emission: + rego: fairness/credit_decision.rego#allow # conformance-checked + circuit: SRC-fair-1.circom#ReasonCodeCheck # constraint-template + tla: HITLOrdering#AdverseGate # invariant reference +evidence: gov.decisions.v1 +``` + +- **Mode of operation (honest)**: GC-IR does not fully *compile* to all three targets today — Rego generation for predicate-style obligations is practical; circuit generation is template-instantiation for a constrained predicate subset; TLA+ linkage is reference + conformance-fixture generation. The verifiable claim is **consistency checking**: shared fixture corpora are executed against the Rego rule, the circuit (witness-level test harness), and the spec's invariant fixtures — any disagreement is a build failure. +- **Why it matters to regulators**: GC-IR is the artifact a supervisor reads to confirm that the proof they verified, the policy that ran, and the protocol that was model-checked all encode the same obligation. It is filed alongside attestations via SIP. +- **Feasibility flag**: GC-IR as consistency-checker is Tier B (buildable, engineering risk); GC-IR as full multi-target compiler is Tier C (research-stage). + +## 15. Hybrid zk-SNARK / zk-STARK Strategy + +| Dimension | Groth16 (SNARK) | PLONK/Halo2 (SNARK) | STARK | +|---|---|---|---| +| Proof size | ~200 B | ~1–10 KB | 50–200 KB | +| Verify cost | 3 pairings (ms) | ms | ms–10s ms | +| Trusted setup | Per-circuit ceremony | Universal (once) | **None** | +| PQ security | No (pairings) | No | **Yes (hash-based)** | +| Best use here | Stable, high-volume circuits (fairness, coverage) + SnarkPack aggregation | Evolving statements without re-ceremony | Long-horizon evidence; transparency-critical claims; PQ hedge | + +**v2.4 hybrid policy**: +1.

Claims that must remain verifiable beyond the pairing-crypto horizon (10y+ retention evidence; treaty-grade attestations) → STARKs, accepting larger proofs. +4. **Bridging**: where a STARK wraps a batch of SNARK verifications (or vice versa) for cost/PQ trade-offs, the wrapper circuit itself goes through GC-IR change control. Recursive composition at this layer is Tier B–C; plan pilots 2029–2031, no compliance dependency before 2032. + +--- + +# PART IV — Multi-Jurisdictional Mapping and ICGC/GASO Layer + +## 16.

Existential and Catastrophic AI Risk Management (institutional translation) + +A financial institution is not an AGI lab, but it is a *deployment amplifier* and a *systemic transmission channel*. Its existential/catastrophic-risk duties translate to: + +1. **Capability-gated deployment (the binding control)**: deny-by-default admission above capability-eval thresholds (autonomy, situational awareness, cyber-offense, persuasion batteries from external eval ecosystems). The institution's strongest x-risk lever is *refusing to deploy what it cannot contain* — encoded as registry/admission policy, board-ratified, exception-free for T0. +2. **Containment depth as cost imposition**: rings R1–R6 + verified kill-switch make the institution a hard target for misuse and a poor escape substrate — defense-in-depth with measured MTTC, never claimed as a guarantee against strongly superhuman systems (see honesty rule, §22). +3. **Systemic transmission dampers**: concentration limits, autonomy ceilings, correlation monitors, and mass-de-autonomization playbooks address the *financial-stability* face of catastrophic risk — correlated AI failure as a 2008-style common-exposure event. +4. **Catastrophic scenario set (CESE + Red Dawn)**: maintained jointly with the risk function — flash-crash via agent herding; credit-system bias cascade; payments-infrastructure agent compromise; model-supply-chain poisoning at vendor; jailbreak epidemic during market stress. Each has a pre-authorized playbook and a capital/liquidity impact estimate feeding ICAAP. +5. **External posture**: contribute incident data (anonymized), fund open verifier/eval tooling, and support compute-governance standards — an institution's marginal x-risk contribution is mostly through the ecosystem it finances and legitimizes; this belongs in the board's risk appetite statement. + +## 19. Ethical Alignment and Value Learning (institutional translation) + +- **Constitution-as-code**: the AI constitution (Phase 0) decomposes into testable behavioral specifications per use case — refusal requirements, escalation duties, customer-fairness commitments — maintained as eval suites and Rego gates, not prose. +- **Value-learning posture (honest)**: general value learning is unsolved (Tier C/D). The institution does not deploy systems whose safety depends on learned values; it deploys systems whose safety depends on *bounded authority + oversight + containment*. Preference-learning components (e.g., RLHF-tuned assistants) are treated as quality features, never as safety controls. +- **Operational ethics machinery**: ethics review board for novel use cases (gates in WorkflowAI Pro); contestability rights (appeal channels per GDPR Art. 22/Consumer Duty wired into decision flows); fairness re-evaluation cadences with statistical-power floors; "red lines" registry (uses the institution will not pursue regardless of legality — e.g., manipulation-optimized retail products), board-ratified and policy-enforced. + +## 20. Global Governance Frameworks and International Cooperation + +- **Real layer (engage now)**: OECD AI Principles and GPAI lineage; the AI-Safety-Institute network (UK AISI, US, EU AI Office scientific panel) for eval methodology; FSB/BIS workstreams on AI in finance; ISO/IEC SC 42 standardization; FS-ISAC for incident sharing. Institutional posture: contribute eval results and incident learnings, adopt emerging eval standards into admission gates, second staff to standards bodies. +- **Fixture layer (build adapters)**: ICGC/GASO per Part IV §17; GAIRA-style systemic-risk telemetry; GACP containment certification. The adapter inventory — attestation, registry export, proof pipelines, SIP endpoints, OSCAL profiles — is identical to what domestic supervisors need, so the investment is no-regret. +- **Cooperation asymmetry management**: where jurisdictions diverge (data localization vs. consolidated supervision; export-control regimes), the obligation lattice + Sovereign Gateway implement most-restrictive-wins with documented derogations; geopolitically driven obligations are treated as *data* updates, keeping the architecture stable under treaty churn. + +## 21. Societal Impacts: Economic Disruption and Bias Amplification + +- **Economic disruption (workforce)**: AI-driven role displacement inside the institution is governed, not just managed — a workforce-transition register (roles affected, reskilling pathways, redeployment rates) reports to the board alongside G-SRI; FCA Consumer Duty logic applied internally ("good outcomes" for staff as a conduct posture). External: credit-model behavior during regional economic shocks is a CESE scenario class (does the AI estate amplify pro-cyclicality?), feeding countercyclical overrides into policy data. +- **Bias amplification**: beyond per-model fairness gates (companion §2.3, §5.7), the *systemic* concern is correlated bias across institutions sharing foundation models — addressed by: lineage-aware fairness analytics (do all models on lineage L share a directional bias?), participation in cross-institution fairness benchmarking (zk-anonymized, Tier B), and concentration limits doubling as bias-monoculture limits. +- **Information-integrity externalities**: GenAI customer-communication systems carry NIST AI 600-1 information-integrity controls (provenance marking, confabulation-rate SLOs with abstention fallbacks); synthetic-content disclosure per EU AI Act Art. 50. +- **Measurement**: a Societal Impact Annex is added to the annual supervisory package: fairness-cohort trends, complaint/appeal volumes and outcomes, workforce-transition metrics, information-integrity SLO attainment — all evidence-linked. + +## 22. Honesty Rules (binding on all artifacts in this volume) + +1. No artifact may claim guaranteed containment of strongly superhuman systems; the claim is *defense-in-depth with measured MTTC plus capability-gated deployment*. +2. No proof may be presented without its input-integrity chain (attestation → signed telemetry → Merkle anchoring) stated alongside. +3. Every speculative construct (ICGC, GASO, SR 26-2, HKMA Fintech 2030, product taxonomy) carries its feasibility-tier label wherever it appears in regulator-facing artifacts. +4. Governance models (ASA, CESE, G-SRI computation, treaty engine) are registered, validated models — no exemption. + +--- + +# PART VII — Regulator-Ready Report Templates + +All recurring regulator-facing reports use the tagged structure below; renderers in G-Stack emit them automatically. + +## 23.

run_runnable_assurance.sh runs all five checks; CI workflow added. - RUNNABLE_ASSURANCE.md documents control->proof mapping and reproduction. --- .github/workflows/runnable-assurance.yml | 72 ++++ governance_artifacts/README.md | 10 + governance_artifacts/RUNNABLE_ASSURANCE.md | 110 ++++++ .../rego/fairness_credit_decision.rego | 47 +++ .../rego/high_impact_credit.rego | 6 +- .../rego/high_impact_credit_test.rego | 42 ++ governance_artifacts/rego/release_gate.rego | 2 + .../rego/release_gate_test.rego | 44 +++ .../run_runnable_assurance.sh | 72 ++++ .../tla/KillSwitchAbstract.cfg | 12 + .../tla/KillSwitchAbstract.tla | 111 ++++++ governance_artifacts/tla/tools/.gitignore | 2 + governance_artifacts/validate_artifacts.py | 8 +- governance_artifacts/zk/.gitignore | 8 + .../circuits/src1_concentration_bound.circom | 117 ++++++ .../zk/circuits/src1_concentration_bound.r1cs | Bin 0 -> 39888 bytes .../zk/circuits/src1_concentration_bound.sym | 270 +++++++++++++ .../generate_witness.js | 20 + .../src1_concentration_bound.wasm | Bin 0 -> 40100 bytes .../witness_calculator.js | 337 ++++++++++++++++ .../src_fair1_reason_code_check.circom | 104 +++++ .../circuits/src_fair1_reason_code_check.r1cs | Bin 0 -> 20316 bytes .../circuits/src_fair1_reason_code_check.sym | 153 +++++++ .../generate_witness.js | 20 + .../src_fair1_reason_code_check.wasm | Bin 0 -> 40527 bytes .../witness_calculator.js | 337 ++++++++++++++++ governance_artifacts/zk/gcir_harness.py | 142 +++++++ .../zk/gcir_obligation_example.yaml | 8 + .../zk/inputs/src1_compliant.json | 9 + .../zk/inputs/src1_compliant.witness.json | 7 + .../zk/inputs/src1_violation.json | 9 + .../zk/inputs/src1_violation.witness.json | 7 + governance_artifacts/zk/package-lock.json | 373 ++++++++++++++++++ governance_artifacts/zk/package.json | 15 + governance_artifacts/zk/run_src1_proof.sh | 91 +++++ 35 files changed, 2562 insertions(+), 3 deletions(-) create mode 100644 .github/workflows/runnable-assurance.yml create mode 100644 governance_artifacts/RUNNABLE_ASSURANCE.md create mode 100644 governance_artifacts/rego/fairness_credit_decision.rego create mode 100644 governance_artifacts/rego/high_impact_credit_test.rego create mode 100644 governance_artifacts/rego/release_gate_test.rego create mode 100755 governance_artifacts/run_runnable_assurance.sh create mode 100644 governance_artifacts/tla/KillSwitchAbstract.cfg create mode 100644 governance_artifacts/tla/KillSwitchAbstract.tla create mode 100644 governance_artifacts/tla/tools/.gitignore create mode 100644 governance_artifacts/zk/.gitignore create mode 100644 governance_artifacts/zk/circuits/src1_concentration_bound.circom create mode 100644 governance_artifacts/zk/circuits/src1_concentration_bound.r1cs create mode 100644 governance_artifacts/zk/circuits/src1_concentration_bound.sym create mode 100644 governance_artifacts/zk/circuits/src1_concentration_bound_js/generate_witness.js create mode 100644 governance_artifacts/zk/circuits/src1_concentration_bound_js/src1_concentration_bound.wasm create mode 100644 governance_artifacts/zk/circuits/src1_concentration_bound_js/witness_calculator.js create mode 100644 governance_artifacts/zk/circuits/src_fair1_reason_code_check.circom create mode 100644 governance_artifacts/zk/circuits/src_fair1_reason_code_check.r1cs create mode 100644 governance_artifacts/zk/circuits/src_fair1_reason_code_check.sym create mode 100644 governance_artifacts/zk/circuits/src_fair1_reason_code_check_js/generate_witness.js create mode 100644 governance_artifacts/zk/circuits/src_fair1_reason_code_check_js/src_fair1_reason_code_check.wasm create mode 100644 governance_artifacts/zk/circuits/src_fair1_reason_code_check_js/witness_calculator.js create mode 100644 governance_artifacts/zk/gcir_harness.py create mode 100644 governance_artifacts/zk/inputs/src1_compliant.json create mode 100644 governance_artifacts/zk/inputs/src1_compliant.witness.json create mode 100644 governance_artifacts/zk/inputs/src1_violation.json create mode 100644 governance_artifacts/zk/inputs/src1_violation.witness.json create mode 100644 governance_artifacts/zk/package-lock.json create mode 100644 governance_artifacts/zk/package.json create mode 100755 governance_artifacts/zk/run_src1_proof.sh diff --git a/.github/workflows/runnable-assurance.yml b/.github/workflows/runnable-assurance.yml new file mode 100644 index 0000000..9a85342 --- /dev/null +++ b/.github/workflows/runnable-assurance.yml @@ -0,0 +1,72 @@ +name: Runnable Assurance (Sentinel v2.4) + +# Executes the runnable proof obligations behind the governance artifacts: +# OPA policy tests, TLA+ TLC model check, GC-IR cross-target harness, and the +# SRC-1 Groth16 concentration-bound proof flow. + +on: + push: + paths: + -
