 All fields except `id` and `name` are optional. Plugins can have any combination of frontend (screen/script), backend (routes), and settings.
 
+`nav.screen` and `nav.icon` are **not consumed anywhere** — the plugin loader's nav dropdown builder always derives the screen id as `"plugin-" + plugin.id` (`static/js/plugin-loader.js`), regardless of what a manifest declares. Don't set either field; they have no effect.

 `version` and `private` are advisory metadata — the plugin loader does not currently consume them, but plugins commonly include them for publishing/tooling purposes.
 
 `description`, `category`, and `icon` are **optional, additive v3 Pedalboard metadata** (surfaced in `/api/plugins`, consumed by the v3 Plugins page `static/v3/plugins-page.js`). `description` is a short one-sentence summary shown under the pedal name. `category` (`audio | creation | practice | game | tools`, free-form; unknown/absent → curated default → `"other"`) picks which pedalboard the plugin sits on. `icon` is an assets-relative thumbnail path (e.g. `"assets/thumb.png"`, ~square ~256×256, same containment rule as `styles`, served via `/api/plugins/<id>/assets/...`); if omitted the loader auto-detects `assets/thumb.png`, and plugins with no thumbnail get a default pedal graphic. All three are backward-compatible — omit them and the plugin still loads. See [docs/plugin-v3-ui.md](docs/plugin-v3-ui.md).

 ### 9. Plugin id must be consistent everywhere
 The plugin id (`folder_library`) must match in:
-- `plugin.json` → `"id"` and `"nav.screen"`
+- `plugin.json` → `"id"`
 - `screen.js` → `PLUGIN_ID` constant and `API` constant (`/api/plugins/folder_library`)
