The SharePoint resource mounts Microsoft SharePoint Online at some prefix such
as `/sharepoint/`. Unlike the single-drive OneDrive resource, it exposes the
full enterprise topology: many sites, each with many document libraries. Site
and drive names are resolved to Microsoft Graph ids automatically, so you mount
once and browse everything you have access to. All operations involve network
I/O to Microsoft Graph. Files are served as raw bytes (no Office filetype
conversion). Uses aiohttp for async Graph access.

For credential setup (tokens, app vs delegated auth, permissions), see the
[SharePoint Setup](/home/setup/sharepoint) guide.

## Config

```python
import os

from mirage import MountMode, Workspace
from mirage.resource.sharepoint import SharePointResource, SharePointConfig

config = SharePointConfig(
    access_token=os.environ["MS_GRAPH_DRIVE_TOKEN"],
    # Optional:
    # tenant_host="contoso.sharepoint.com",  # restrict to one tenant host
    # site_filter="Engineering",             # narrow the site search
    # site="Engineering",                    # mount one site
    # drive="Documents",                     # mount one library
    # key_prefix="team/reports",             # mount one folder subtree
    # timeout=30,
    # max_retries=5,
)

resource = SharePointResource(config)
ws = Workspace({"/sharepoint": resource}, mode=MountMode.WRITE)
```

`SharePointResource(config)` takes a `SharePointConfig` object with a Microsoft
Graph bearer token. No drive id is required: the resource discovers sites and
drives for you. Both `READ` and `WRITE` modes are supported.

### Config Reference

| Field          | Required | Description                                                       |
| -------------- | -------- | ----------------------------------------------------------------- |
| `access_token` | Yes      | Microsoft Graph OAuth2 bearer token (string or callable provider) |
| `tenant_host`  | No       | Restrict resolution to a single SharePoint host                   |
| `site_filter`  | No       | Search term passed to `/sites?search=` to narrow discovery        |
| `site`         | No       | Scope the mount to one site; use together with `drive`            |
| `drive`        | No       | Scope the mount to one document library; use together with `site` |
| `key_prefix`   | No       | Folder path exposed as the mount root in a scoped library         |
| `timeout`      | No       | Request timeout in seconds (default `30`)                          |
| `max_retries`  | No       | Max retries on `429`/`5xx` with backoff (default `5`)             |

`access_token` accepts either a static string or a `Callable[[], str]` provider.
With a callable, the resource refreshes the token on `401`, so long-running
mounts survive token expiry.

## Filesystem Layout

SharePoint paths follow the structure `/{site}/{library}/{path}`. The first two
levels are virtual (sites and drives), and everything below is a real Graph
driveItem.

- **Level 0** (`/sharepoint/`): lists all accessible sites
- **Level 1** (`/sharepoint/{site}/`): lists document libraries (drives) in that site
- **Level 2+** (`/sharepoint/{site}/{library}/...`): lists files and folders

For example:

```text
/sharepoint/
  Engineering/
    Documents/
      spec.md
      deck.pptx
    Reports/
      q1.csv
  Marketing/
    Shared Documents/
      brand.pdf
```

Path mapping: virtual `/sharepoint/Engineering/Documents/spec.md` resolves the
site `Engineering` to a site id, the library `Documents` to a drive id, then
reads the driveItem at `/root:/spec.md`.

When `site` and `drive` are configured, those two namespace levels disappear.
Adding `key_prefix="team/reports"` makes that folder the mount root, so virtual
`/sharepoint/q1.csv` resolves to the driveItem at
`/root:/team/reports/q1.csv`.

## Versioning and Snapshots

SharePoint keeps per-file version history. The resource exposes it the same way
the OneDrive and S3 backends do:

- **Fingerprint** is the driveItem `cTag`, so normal reads and `stat` reflect
  the current content without extra Graph calls.
- **Snapshots** pin each path to a Graph driveItem version id. Replaying a
  snapshot reads `/versions/{id}/content`, giving time-travel to the exact bytes
  captured at snapshot time.
- **Restore** writes a previous version back as the current one.

This makes the SharePoint resource `SUPPORTS_SNAPSHOT = True`.

## Cache

The SharePoint resource caches site, drive, and directory listings via
`IndexCacheStore` to reduce repeated Graph calls during traversal.

## Example

```python
import asyncio
import os

from mirage import MountMode, Workspace
from mirage.resource.sharepoint import SharePointResource, SharePointConfig

config = SharePointConfig(access_token=os.environ["MS_GRAPH_DRIVE_TOKEN"])
resource = SharePointResource(config)


async def main() -> None:
    ws = Workspace({"/sharepoint/": resource}, mode=MountMode.WRITE)

    # list sites, then drives in the first site
    r = await ws.execute("ls /sharepoint/")
    print(await r.stdout_str())

    r = await ws.execute("ls /sharepoint/Engineering/")
    print(await r.stdout_str())

    await ws.execute(
        "echo 'hello from mirage' > /sharepoint/Engineering/Documents/note.txt")

    r = await ws.execute("cat /sharepoint/Engineering/Documents/note.txt")
    print(await r.stdout_str())

    r = await ws.execute("tree /sharepoint/Engineering/Documents/")
    print(await r.stdout_str())


if __name__ == "__main__":
    asyncio.run(main())
```

Runnable versions live at `examples/python/sharepoint/sharepoint.py` (command
matrix) and `examples/python/sharepoint/sharepoint_vfs.py` (FUSE mount).

## Shell Commands

The SharePoint resource supports the full set of shell commands since it
operates on real file content (text, binary, JSON, CSV, etc.). Large files
benefit from range reads to avoid downloading entire items.

### Read Commands

| `touch` | Create empty file or update timestamp |
| `tee`   | Write stdin to file and stdout        |

### Path Utilities

| Command    | Notes                     |
| ---------- | ------------------------- |

## Use Cases

- **AI agents accessing org documents**: Mount enterprise SharePoint for agents to read and process files across many sites
- **Multi-site discovery**: Browse every accessible site and library from a single mount, no drive ids to manage
- **Versioned document workflows**: Snapshot and replay exact file states over time
- **FUSE mounting**: Expose SharePoint through a virtual FUSE mount for external tools

## SharePoint vs OneDrive

Both backends talk to Microsoft Graph driveItems and behave identically below
the drive level. Choose by topology:

- Use **[OneDrive](/python/resource/onedrive)** for a single drive (personal
  OneDrive, OneDrive for Business, or one targeted SharePoint library via
  `drive_id` / `site_id`).
- Use **SharePoint** for enterprise scenarios with many sites and libraries that
  you want to discover and traverse without knowing drive ids up front.
