+# Attribute GC — TriliumNext Maintenance Tool
+
+A garbage collector for TriliumNext attributes. Scans all notes to find broken relations, unused labels, rare attributes, and near-duplicate names. Lets you preview and safely delete them — either individually or in batch.
+
+## Features
+
+- **Full scan** — Reads all notes via `froca` (TriliumNext frontend cache) or `api.runOnBackend` (classic Trilium). Classifies every label and relation by usage count and health.
+- **Broken relation detection** — Finds relations pointing to deleted or missing target notes.
+- **Rare attribute flagging** — Highlights attributes used ≤2 times, plus temp/draft/test patterns.
+- **Semantic duplicate finder** — Uses Levenshtein distance to surface near-identical names (`pipeline` vs `pipelne`, `autor` vs `autores`).
+- **Dry run mode** — Toggle on to preview what would be deleted without making changes.
+- **Batch operations** — Auto-select all problematic attributes, then delete them in one click.
+- **Scoped CSS** — All styles are prefixed under `#attrgc-root` so nothing leaks into the Trilium UI.

+
+## 🌐 Language / Idioma
+
+**Note on language:** Since I am from Brazil, the interface and text within this tool are currently in **Brazilian Portuguese (PT-BR)**. 
+However, you can easily translate them to English or your preferred language by simply opening the code files inside Trilium and replacing the text strings.
+
+---
+
+## How it works
+
+### Scan (read)
+
+```
+glob.getActiveContextNote() → froca → froca.notes / froca.attributes
+```
+
+The note accesses TriliumNext's frontend object cache directly. All notes and their attributes are already in memory — no backend calls needed.
+
+### Delete (write)
+
+```
+note.getOwnedAttributes(type, name) → attr.update({ isDeleted: true })
+```
+
+Finds attribute objects on each note via the standard prototype method, then marks them deleted through the entity's own `update()` method. The change syncs to the backend automatically.
+
+For **relations**, only broken instances (target note missing or deleted) are removed. For **labels**, all instances of that name are removed.
+
+### Classic Trilium fallback
+
+If `api.runOnBackend` is available (classic Trilium), the tool uses SQL for scanning and `removeLabel` / `removeRelation` for deletion.
+
+## Installation
+
+1. In TriliumNext, import the .zip file (the plugin) into any root note of your choice (e.g., Tools, Plugins, or Add-ons).
+
+2. The import contains two notes: a Render note and an HTML code note. Simply click on the Render note to view the panel.
+
+## Usage
+
+1. Click **Escanear** — the tool reads all notes and shows a dashboard of attribute stats.
+2. Use the filter tabs (**Quebrados**, **Raros**, **Sem uso**, **Sistema**) and search bar to narrow down.
+3. Click **Auto-selecionar problemáticos** to check all non-system problematic attributes, or tick individual checkboxes.
+4. **Toggle Dry Run OFF** (the yellow banner disappears).
+5. Click **Executar limpeza** → confirm the dialog. The tool removes the selected attributes.
+6. A green banner flashes briefly, and a re-scan runs to confirm the new counts.
+
+The individual **remover** button on each row works the same way — skips the batch dialog.
+
+## Protected attributes
+
+These system/internal attributes are locked and cannot be deleted:
+
+`template`, `workspace`, `iconClass`, `cssClass`, `run`, `runOnInstance`, `runAtStartup`, `shareAlias`, `shareHiddenFromTree`, `archived`, `pinned`, `bookmarked`, `weight`, `color`, `renderNote`, `child`, `runOnNoteCreation`, `noteType`, `mime`, `shareCss`, `shareJs`, `shareRaw`, `shareDisallowRobotIndexing`, `keyboardShortcut`, `label`, `relation`, `promoted`, `multiplicity`, `labelDefinition`, `relationDefinition`, `toc`, `readOnly`, `excludeFromExport`, `appCss`, `appTheme`, `sorted`, `sortDirection`, `sortFoldersFirst`, `top`, `hide`, `hidePromotedAttributes`, `disableVersioning`, `calendarRoot`, `dateNote`, `datePattern`, `inbox`, `sqlConsole`, `searchHome`, `hoistedNote`, `similarNotes`, `versioningLimit`, `mapRootNoteId`, `system`, `root`
+
+## Compatibility
+
+| Environment | Scan | Delete |
+|---|---|---|
+| **TriliumNext** | `froca.notes` | `attr.update({ isDeleted: true })` |
+| **Classic Trilium** | `api.sql.getRows` | `note.removeLabel` / `note.removeRelation` |
+| **Browser (demo)** | Mock data | Simulated (noop) |
+
+## Technical notes
+
+- The tool renders as a **Render Note** in TriliumNext — no build step, no dependencies.
+- All CSS is scoped under `#attrgc-root` to prevent style conflicts with the Trilium UI.
+- The delete path uses `getOwnedAttributes(type, name)` (prototype method on `FNote`) to retrieve attribute objects, then calls `update({ isDeleted: true })`. No raw SQL modifications — all changes go through the entity lifecycle.
+- Broken relations are detected by building a `Set` of all valid `noteId`s and checking whether a relation's target exists in that set.
