## Summary  
The paper introduces the **Agentic Posture Vulnerability (APV)** as a task‑conditioned abstraction that captures persistent gaps between an AI coding agent’s mandate and its authority, extending beyond event‑driven CVEs. By linking invariant postures to their runtime manifestations across components, APV provides a durable record of exposure until the gap is closed by narrowing authority or adding controls. This framework operationalizes existing weaknesses such as excessive agency, weak task‑bound authorization, and inadequate control composition, offering a systematic way to manage ongoing vulnerabilities in deployed agents.

## Key Contributions  
- **Introduces APV** as a durable record for composed agent‑control exposure that remains open until authority is narrowed, a missing control is added, risk is accepted, or closure is verified.  
- **Distinguishes APVs from traditional CVEs and OWASP Excessive Agency**, clarifying their scope as task‑conditioned posture exposures rather than product defects.  
- **Provides a control‑and‑closure matrix** along with tooling implications, enabling concrete operational steps for vulnerability lifecycle management.

## Methodology  
The authors begin by reviewing existing security frameworks that address agency, authorization, and control composition, then synthesize these into the APV concept. They employ a field vignette to illustrate how an AI coding agent’s posture can manifest differently across tasks, using a thresholded definition to enumerate six recurring exposure patterns. This analytical approach yields a structured vulnerability lifecycle and a minimum record template for tracking APVs.

## Results  
The study identifies six recurring APV patterns that recur when postures outlive their intended scope. A detailed vulnerability lifecycle is defined, including opening, risk acceptance, closure verification, and re‑opening triggers. The control‑and‑closure matrix maps each posture to specific authority reductions or added controls required for closure. Tooling implications suggest integration with CI/CD pipelines and runtime observability platforms.

## Significance  
APV shifts the focus from reactive CVE tracking to proactive management of persistent agency gaps, aligning security programs with long‑term deployment realities. By providing a reusable abstraction and actionable matrix, it helps organizations maintain control over AI coding agents across evolving tasks and components.
