## Overview

Vault is a distributed, S3-compatible object store. S3 clients authenticate and enter through the HTTP API, whose router delegates requests to the application and storage layers; storage encodes objects across drives and maintains metadata. Background scanning, healing, lifecycle, and replication extend that data path, while IAM, encryption, cluster RPC, notifications, audit, and administration provide governance and operations. The README documents several links for subsystems whose source was not sampled; those documented links are included, while uncertain internal wiring is omitted.

Main entry points: [`vault/storage_core/storage_facade.py`](https://github.com/dheer46/vault_promptathon/blob/main/vault/storage_core/storage_facade.py) (Storage Facade), [`vault/app_facade/facade.py`](https://github.com/dheer46/vault_promptathon/blob/main/vault/app_facade/facade.py) (Application Facade), [`vault/api_surface/server.py`](https://github.com/dheer46/vault_promptathon/blob/main/vault/api_surface/server.py) (API Surface), [`vault/ops/replication.py`](https://github.com/dheer46/vault_promptathon/blob/main/vault/ops/replication.py) (Bucket Replication)
