Applications Maintained by Dynamic Harness-Driven Development

A general operating model for collecting runtime evidence, planning repairs, and keeping AI-assisted products stable

This application is maintained through dynamic harness-driven development. The method treats harness results as operational evidence, converts failures into bounded repair plans, and preserves learning without exposing internal implementation details.

動的ハーネス駆動開発により保守されるアプリケーション

Runtime evidenceを収集し、改修計画へ変換し、AI支援プロダクトを安定運用するための汎用モデル

このアプリは動的ハーネス駆動開発により保守されています。Harness結果を運用証跡として扱い、失敗を境界付きの改修計画へ変換し、内部実装の詳細を公開せずに学習を残す方法です。

Harness-Driven Development: Building Agentic Systems from Runtime Evidence Backward

A development method where scenarios, gates, scorecards, and repair boundaries are designed before implementation

Harness-driven development treats the dynamic harness as the primary specification. Instead of writing agent code first and testing it later, teams define runtime episodes, failure taxonomies, gates, and evidence contracts first, then let implementation converge toward measurable behavior.

ハーネス駆動開発:Runtime Evidenceから逆算してAgentic Systemを作る

実装より先にscenario、gate、scorecard、repair boundaryを設計する開発方法論

ハーネス駆動開発では、dynamic harnessをテスト補助ではなく主仕様として扱う。promptやtoolを書く前に、runtime episode、failure taxonomy、scorecard、authority boundaryを定義し、実装を測定可能な振る舞いへ収束させる。

Governed Auto-Implementation: How a Dynamic Harness Turns Research Intent into Code

From design note to implementation plan, patch, replay, and approval-gated merge

Automatic implementation becomes useful only when the system can prove what changed, why it changed, which runtime episodes improved, and which authority boundaries were touched. This article defines the governed auto-implementation loop inside a dynamic harness.

ガバナンス付き自動実装:Dynamic Harnessが研究意図をコードへ変換する仕組み

設計メモから実装計画、パッチ、再現実行、承認ゲート付きマージまで

自動実装が有用になるのは、何がなぜ変わり、どのruntime episodeが改善し、どのauthority boundaryに触れたかを証明できる時だけである。本稿はdynamic harness内部のgoverned auto-implementation loopを定義する。

Autonomous Repair Harness: Turning Runtime Failures into Safe, Reviewable System Improvements

Failure episodes, repair proposals, rollback envelopes, and approval boundaries for self-healing agentic systems

Automatic repair is the next step after automatic implementation. A dynamic harness can observe runtime failures, classify drift, draft repairs, replay evidence, and route patches through rollback and approval boundaries without allowing agents to rewrite their own constitution.

自動改修ハーネス:Runtime Failureを安全でReview可能な改善へ変換する

Failure episode、repair proposal、rollback envelope、approval boundaryによるself-healing agentic system

自動改修は自動実装の次段階である。Dynamic harnessはruntime failureを観測し、driftを分類し、repairを下書きし、evidenceをreplayし、rollbackとapproval boundaryを通してpatchをrouteできる。ただしagentが自分自身の憲法を書き換えることは許さない。

Dynamic Harness and Phase-Space Control: From virtual-talent to MARIA OS

Reframing runtime episodes, failure taxonomies, dynamic scorecards, repair proposals, and controlled self-healing as phase control for agentic society

The central question for agentic systems is shifting from model intelligence to runtime phase control. This article defines the Dynamic Harness as a Runtime Governance Layer that observes, evaluates, and controls the phase space of an agent runtime, connecting MARIA OS research with implementation lessons from bonginkan/virtual-talent.

動的ハーネスと位相空間制御:virtual-talentからMARIA OSへ

runtime episode、failure taxonomy、dynamic scorecard、repair proposal、controlled self-healingを、Agentic Society Runtimeの位相制御として再定義する

AI Agentの時代における本質的な問いは、モデルがどれほど賢いかではなく、知能がどの位相に入り、どの位相から戻れなくなるかである。本稿は、bonginkan/virtual-talentのProducer AIで進むDynamic Harness実装を踏まえ、MARIA OSにおけるハーネスをRuntime Governance Layer、さらにAgent runtimeの位相空間を制御する層として定義する。runtime episode、failure taxonomy、dynamic scorecard、repair proposal、controlled self-healingを軸に、静的テストから動的制御へ移行する設計原理を整理し、企業OSとAgentic Societyへ拡張する研究課題を示す。
