 ## Code
 
-- `media-scrape/slopbot/` holds the bot core: client lifecycle, the `ScrapeBackend` implementation,
-  and the invite helper.
-- discord.js is a dependency of the daemon package (`poc/package.json`), the same way the MCP SDK
-  is. The code stays in `media-scrape/`; the daemon only mounts it.

+- discord.js lives in `media-scrape/package.json`; the folder is its own pnpm workspace root.
+- The mapping is duck-typed, so the tests run without a token. The live Discord shapes were checked
+  against the discord.js 14 typings, but a real login is still owed at C8.
 - The Bot tab shows connection state, the guilds slopbot is in, the active scrape, and the queue.
   It also renders the invite URL from the client ID.

 ## Status
 
-Design approved 2026-09-16. Scaffold added 2026-09-16: `media-scrape/slopbot/` (config loader and
-invite helper) and the discord.js dependency in `media-scrape/package.json`. Unused until
-checkpoint C4 in [CURRENT.md](../CURRENT.md).
+Backend implemented 2026-09-16 (C4): mapping, paging, and client lifecycle, tested with a fake
+fetcher. Not wired into the daemon yet; that is C5. A live login with a real token is owed at C8.
+Checkpoints: [CURRENT.md](../CURRENT.md).
