// autonomous engineering control plane & verification ledger

HowlPlane ハウルプレーン // 2026

Name: HowlPlane
Author: William Elias

Engineered by William Elias, HowlPlane is a structured control plane for multi-agent software engineering. It combines deterministic routing, adversarial falsification reviews, deterministic verification, and explicit human authority boundaries.

AXIOM // ORCHESTRATION WITHOUT ARBITRARY DRIFT. Agents propose implementations; deterministic reviewers falsify assumptions; verification suites test live evidence before humans approve changes.

TOPOLOGY // TASK SPEC → ROUTING → ADVERSARIAL AUDIT → HUMAN GATE STATUS: LIVE

Deterministic Router

Classifies TaskSpecs by risk, domain, and required skills without LLM variance.

[DETERMINISTIC]

Multi-Agent Execution

Specialized worker agents implement code in isolated worktree branches.

[ISOLATED]

Adversarial Review

Independent falsifiers seek defects, security gaps, and ungrounded claims.

[ADVERSARIAL]

Human Authority

Evidence ledger presents reconciled facts for human approval sign-off.

[HUMAN GATE]

SECTION // 01 System Overview

HP-MOD-OVERVIEW

HowlPlane coordinates complex multi-agent engineering workflows. Rather than letting agents operate as unstructured chat loops, HowlPlane decomposes work into canonical TaskSpecs, validates changes with deterministic verification suites, and enforces strict human authority gates before mutations are applied.

SECTION // 04 HowlFrame Integration

HP-MOD-HOWLFRAME

HowlPlane integrates closely with HowlFrame for capability-checked execution policies. While HowlPlane manages agent orchestration and workflow state, HowlFrame compiles and executes deterministic policy bytecode that guards dangerous runtime capabilities.

SECTION // 04B Control Plane Architecture & Questions

HP-MOD-QA

What does an AI engineering control plane do?

Direct Answer: An AI engineering control plane orchestrates autonomous coding agents through deterministic lifecycle stages rather than unconstrained prompt loops. HowlPlane classifies tasks, assigns bounded roles, dispatches work, manages execution timeouts, enforces adversarial falsification gates, and verifies test evidence before requesting human sign-off.

How do persistent coding agents run continuously across sessions?

Direct Answer: Persistent operation requires decoupling runtime state from transient LLM context windows. HowlPlane coordinates multi-agent workflows with supervisory state tracking, failover policies across provider pools, and integrates with HowlRelay for durable trajectory journals and resumable handoff packages.

How does HowlPlane prevent arbitrary agent drift?

Direct Answer: Through adversarial verification and independent reviewer gates. Before any proposed patch is considered, HowlPlane routes the change to independent falsification reviewers whose sole objective is to discover edge cases, regressions, or spec violations. The change cannot proceed to human approval without verifiable test evidence and automated gate passage.

SECTION // 05 Ecosystem Governance

HP-MOD-GOV

HowlPlane operates as the orchestration layer within the broader Howl Ecosystem alongside HowlFrame (Compiler & VM), HowlChangeOps (Release Authority), HowlNotes (Knowledge Notebook), and HowlBoard (Evaluation Telemetry).
