+## What is built, as of 2026-08-14
+
+The plugin system works end to end for a plugin that has an `api/router.ts`. Verified against a running
+server, with **no restart at any point**:
+
+```
+/api/example/ping BEFORE install   404
+AFTER install                      200  {"plugin":"example","ok":true}
+AFTER disable                      404
+AFTER enable                       200
+AFTER uninstall                    404
+core routes throughout             200

+### Not wired yet
+
+- **The schema push.** A plugin with `db/schema.ts` installs, but its tables are not created. Marked
+  `[open]` in the router.
+- **The sidecar's PM2 entry.** A plugin with `sidecar/` installs, but no process starts. This is the same
+  hole `app-store/pm2.ts:23-29` documents for the app store, and it is the next thing to build.
+- **Websocket providers.** `server.reload({ routes })` is proven but not called; Bun's route table is
+  still the six hardcoded providers.
+- **Totality across plugin routes.** `PROTECTED_API_PREFIXES` remains the core list, so plugin mounts are
+  not covered by the boot check — and the check is reading the wrong list anyway (see below). The
+  assertion wants moving into `buildHonoApp`, which is now the single place routes are mounted.
+
+### Deliberately not done
+
+**Offscale is not extracted.** The infrastructure is ready for it, but moving it means deleting working
+code across ~50 files, and that should happen with someone watching rather than unattended.

 ## The state of the app store, as found
 
 It **is** the plugin system, roughly 90% built, with one structural hole.
