# ProductPhase {X.Y} — Architecture Story for {project}

## Abstract

This document tells the architecture story of **{project}** in **ProductPhase {X.Y}**.
It explains why the system exists, which architectural requirements (ASRs) and
decisions (ADRs) shape it, how those decisions manifest as feature Specs and
interface Contracts (when used), and how the A2C workflow was used to implement
and evolve the product in this phase.

It is intended as a narrative overview for engineers, architects, and
stakeholders who want a coherent, end-to-end understanding of this phase
without reading each ASR/ADR/spec/contract file individually.

**Canonical form:** Markdown in the repository (typically under `docs/architecture/`).
PDF, slides, or other exports are optional presentation artifacts for human
discussion — not a substitute for the Markdown source.
