# {Title}

## Overview

{What this system/component is, why it exists, how it fits into the architecture.}

---

## Current State

{What is implemented now, what changed since the original design.}

---

## Design

{Technical details: data flow, interfaces, algorithms, constraints.}

---

## Decision References

{Link to relevant D-records and explain how they constrain this design.}

---

## Open Questions

{Anything unresolved. Link to Q-records if filed.}
