A cognitive orchestration platform that choreographs AI model pipelines through recursive verification layers — the next evolution of Plan-Execute-Verify thinking, repurposed for distributed agent swarms.

Imagine a blueprint that doesn't just sit on paper — it breathes. NeuroStack Architect is a self-validating orchestration harness designed for developers who build with large language models at scale. Inspired by the Plan-Execute-Verify paradigm, this repository reimagines the three-phase pipeline as a living architecture where every plan is questioned, every execution is observed, and every verification seeds the next iteration.

Think of it as a conductor for AI symphonies — where each instrument (agent, model, or tool) plays its part, but the conductor listens, corrects, and rewrites the score in real time.

Unlike traditional coding harnesses that treat verification as a final gate, NeuroStack Architect embeds hook-driven verification at every decision node. The harness doesn't just check output — it audits the intent, process, and result across three distinct cognitive layers:

If you're stitching together LLM chains, agent networks, or multi-model workflows, you've likely encountered the silent drift problem — where pipelines produce plausible but wrong outputs. NeuroStack Architect solves this by introducing verification contracts that every execution unit must satisfy before the next phase begins.

The verification engine speaks the language of your data. Whether your prompts are in English, Mandarin, Arabic, or Spanish, the hook system adapts its validation grammar to the linguistic context of the request. This isn't translation — it's semantic mirroring.

Every hook in the pipeline can be toggled, tuned, or replaced without restarting the orchestration layer. This hot-swappable architecture means your 24/7 workflows never sleep — and your verification logic can evolve while the system hums.

• Intent Decomposition Engine — breaks high-level goals into atomic, verifiable micro-tasks
• Constraint Propagation — ensures every sub-plan inherits global boundaries
• Conflict Detection — identifies contradiction between plan steps before execution begins

• Deterministic Snapshots — every execution branch is captured as an immutable state object
• Graceful Degradation — when a step fails, the harness reroutes instead of crashing
• Parallel Path Awareness — multiple execution threads are tracked and synchronized at verification gates

• Recursive Verification Hooks — each verification can spawn sub-verifications for complex outputs
• Semantic Equivalence Checking — goes beyond string matching to verify meaning preservation
• Bias and Drift Detection — automated scanning for output patterns that deviate from intended distribution

• Plugin Architecture — attach custom verifiers, executors, or planners without modifying core
• Event Logging — every hook fires structured logs suitable for downstream analysis
• Adapter Layer — connect to any model provider, vector store, or external API through a unified interface

The harness is organized around three concentric circles:

1. Core Engine — the Plan-Execute-Verify loop with hook injection points
2. Plugin Registry — where custom planners, executors, and verifiers are registered
3. Workspace — the configuration, state storage, and output directory

Each component communicates through typed event channels, meaning you can observe, intercept, or replay any message in the system.

NeuroStack Architect embraces convention over configuration — but convention is just a starting point. Every phase can be tuned through a single configuration document that reads like a specification:

{
  "plan": {
    "depth": 5,                     // Maximum decomposition depth
    "conflictThreshold": "strict",  // Reject on any conflict
    "language": "auto"              // Auto-detect from input
  },
  "execute": {
    "maxRetries": 3,
    "snapshotInterval": "everyStep",
    "parallelism": "bounded"
  },
  "verify": {
    "recursive": true,
    "semanticModel": "default",
    "driftWindow": 100              // Compare against last 100 verifications
  }
}

Every verification hook undergoes its own validation suite before integration. This meta-verification ensures that the harness's ability to catch errors doesn't itself become a source of error. The result is a system where trust is earned, not assumed.

NeuroStack Architect is a structural tool for improving the reliability of AI-generated outputs. No verification system can guarantee 100% accuracy, completeness, or safety of model outputs. Users are encouraged to implement human-in-the-loop oversight for high-stakes applications. The authors assume no liability for decisions made based on outputs processed through this harness.

This repository is the seed. The forest is what you build around it. Contributions that extend the verification vocabulary, introduce new planner strategies, or improve the semantic checking engine are welcome. The hook system is designed to be extended, not replaced.

Current release: Beta 2026.1
Focus areas for upcoming iterations:

• Real-time verification visualization dashboard
• Cross-model verification contracts (compare outputs across providers)
• Temporal drift analysis across extended workflow runs

Built with the conviction that verification isn't a step — it's a culture.
