Overview

The Verification Integrity Commander operates as an L3 Strategic Command authority within the Prismatic Platform's quality-assurance domain, responsible for maintaining the integrity of the platform's formal verification infrastructure. This agent ensures that the five core Lean4 theorems -- which mathematically guarantee safe platform evolution -- remain valid, complete, and correctly integrated with the runtime verification pipeline.

The five core theorems form the mathematical foundation of the platform's evolution safety guarantees: (1) the Quality Monotonicity Theorem, proving that quality scores never decrease across evolution generations; (2) the State Transition Safety Theorem, proving that all state transitions preserve system invariants; (3) the Convergence Theorem, proving that the autonomous evolution process converges to stable optima; (4) the Composition Preservation Theorem, proving that composed operations preserve individual component properties; and (5) the Rollback Completeness Theorem, proving that any evolution step can be fully reversed without information loss.

The agent coordinates with the white-verifier-commander for proof artifact management, the white-invariant-prover for formal proof construction, and the SEADF evolution pipeline for integration of verification results into the autonomous evolution process. All verification activities comply with the NABLA Infinity epistemic framework and the NO MERCY doctrine's zero-tolerance policy for unverified claims.

Architecture

The Verification Integrity Commander is built on a layered architecture that separates theorem management, proof validation, runtime integration, and reporting into distinct OTP processes.

VerificationIntegrity.Supervisor
+-- TheoremRegistry.Server      (canonical theorem storage and versioning)
+-- ProofValidator.Worker        (Lean4 proof checking and completeness)
+-- RuntimeBridge.Server         (theorem-to-runtime assertion mapping)
+-- IntegrityMonitor.Worker      (continuous verification health monitoring)
+-- ReportGenerator.Server       (verification status reporting)

The TheoremRegistry maintains the canonical versions of all five core theorems along with their Lean4 proof artifacts, version history, and dependency graphs. The ProofValidator invokes Lean4 proof checking to verify that proofs remain valid after theorem modifications or dependency changes. The RuntimeBridge maps formal theorem statements to runtime assertions that are evaluated during platform operation, ensuring that mathematical guarantees translate to actual runtime behavior. The IntegrityMonitor continuously checks that the verification pipeline is healthy and that all theorems maintain valid proofs.

The architecture follows the supervision tree pattern with rest_for_one strategy, ensuring that the TheoremRegistry (the most critical component) is always available, while downstream components restart cleanly if they encounter failures.

Core Capabilities

The Verification Integrity Commander provides five primary capabilities that together ensure the mathematical safety of platform evolution.

Theorem Lifecycle Management maintains the canonical versions of the five core Lean4 theorems, tracking their evolution across platform generations. Each theorem modification is version-controlled with full provenance, and the agent ensures that theorem versions are always consistent with the current platform state.

Proof Completeness Verification checks that every theorem has a complete, valid Lean4 proof. The agent detects partial proofs, proofs that rely on unverified axioms (sorry in Lean4), and proofs that have become invalid due to changes in underlying definitions or lemmas.

Runtime Assertion Mapping bridges the gap between formal mathematical proofs and runtime behavior. Each theorem is mapped to a set of runtime assertions that can be evaluated during platform operation. The agent verifies that the mapping is sound -- that the runtime assertions are logical consequences of the formal theorem -- and that the assertions are actually being checked during execution.

Cross-Theorem Dependency Analysis tracks dependencies between theorems, shared lemmas, and common definitions. When one theorem or lemma is modified, the agent determines which other theorems are affected and triggers re-verification of the affected dependency chain.

Evolution Gate Integration provides a verification gate in the SEADF evolution pipeline. Before any autonomous evolution step is applied, the agent verifies that all five core theorems remain valid under the proposed change. If any theorem would be invalidated, the evolution step is blocked until the theorem can be updated and re-proven.

Implementation

The core theorem registry is implemented as an OTP GenServer that manages theorem storage, versioning, and validation coordination.

The verify_all/0 function checks all five core theorems by invoking the Lean4 proof checker through the ProofValidator module, counting associated runtime assertions, and publishing telemetry events for each verification result. The evolution_gate_check/1 function determines whether a proposed evolution change would invalidate any theorem, blocking unsafe evolution steps.

Operational Workflow

The Verification Integrity Commander operates in three modes: scheduled integrity checks, on-demand verification, and evolution gate enforcement.

Scheduled Integrity Checks run every 60 minutes by default, verifying all five core theorems and their associated proofs. Results are stored in the verification history for trend analysis and published through telemetry for monitoring dashboards.

On-Demand Verification is triggered by explicit command invocation or by events that may affect theorem validity, such as changes to shared definitions, lemma updates, or platform dependency modifications. The agent performs targeted re-verification of affected theorems and their dependency chains.

Evolution Gate Enforcement activates before every SEADF autonomous evolution step. The agent analyzes the proposed change, determines which theorems are affected, and checks whether their proofs remain valid under the change. If any theorem would be invalidated, the evolution step is blocked with a detailed report identifying the failing theorems and the specific proof steps that break.

The full verification workflow proceeds through five phases: (1) theorem loading from the registry, (2) proof artifact retrieval and integrity checking, (3) Lean4 proof validation, (4) runtime assertion mapping verification, and (5) result publication and history recording.

NABLA Compliance

The Verification Integrity Commander operates under strict NABLA Infinity epistemic governance.

Signal Plurality: Every theorem verification requires at least two independent signals: the Lean4 formal proof check and the runtime assertion evaluation. A theorem is only marked as valid when both signals agree.

Contradiction Preservation: When a theorem's formal proof and runtime assertions produce conflicting results (formal proof valid but runtime assertion failing, or vice versa), both results are preserved and escalated for investigation. The agent does not suppress contradictions.

Provenance Mandatory: Every verification result carries a complete provenance chain: theorem version, proof artifact hash, Lean4 checker version, runtime assertion identifiers, and evaluation timestamp. This provenance is immutable once recorded.

Unknown Valid: When the Lean4 checker times out or encounters an internal error, the theorem status is set to :checking rather than :invalid. The agent acknowledges uncertainty rather than making false claims about proof validity.

All verification claims pass through Trinity Gate: structural consistency (the theorem dependency graph forms a valid DAG), logical consistency (proof steps follow from their premises), and formal necessity (the Lean4 proof is machine-checked).

Configuration

config :prismatic_agents, Prismatic.Agents.VerificationIntegrity,
  check_interval: :timer.minutes(60),
  lean4_timeout: :timer.minutes(5),
  lean4_path: System.get_env("LEAN4_PATH", "/usr/local/bin/lean"),
  proof_artifacts_dir: "priv/proofs/core/",
  runtime_assertions_enabled: true,
  evolution_gate_enabled: true,
  max_verification_history: 1000,
  telemetry_prefix: [:prismatic, :verification_integrity]

Parameter	Default	Description
`check_interval`	60 minutes	Time between scheduled integrity checks
`lean4_timeout`	5 minutes	Maximum time for Lean4 proof checking per theorem
`proof_artifacts_dir`	`priv/proofs/core/`	Directory containing Lean4 proof files
`evolution_gate_enabled`	`true`	Whether the SEADF evolution gate is active
`runtime_assertions_enabled`	`true`	Whether runtime assertion checking is active

Performance

The agent is optimized for rapid verification with minimal impact on the evolution pipeline.

Metric	Target	Measured
Single theorem verification	< 60 seconds	15-45 seconds
Full five-theorem check	< 5 minutes	1-3 minutes
Evolution gate check	< 30 seconds	5-20 seconds
Runtime assertion evaluation	< 100 ms	10-50 ms
Proof artifact loading	< 1 second	200-500 ms
Memory footprint	< 100 MB	40-70 MB

The evolution gate check is optimized through dependency analysis: only theorems affected by the proposed change are re-verified, reducing the typical gate check to 1-2 theorem verifications rather than the full five. Proof artifacts are cached in memory after initial loading, and incremental proof checking is used when only specific lemmas have changed.
