fix: AI chat receives live editor content instead of stale disk content

handleContentChange now syncs content to tab state on every editor
change (not just on Cmd+S save). This ensures the AI panel's context
snapshot always contains the current editor body, fixing the bug where
the AI reported empty note bodies for unsaved edits.

Root cause: pendingContentRef buffered content for save but never
updated notes.tabs[].content, so activeTab?.content (used by the AI
context builder) always reflected the last-saved disk content.

-## Summary
-
-Refactored three CodeScene hotspot files to improve code health scores:
-
-| File | Before | After | Approach |
-|------|--------|-------|----------|
-| Editor.tsx | 7.82 (cc=35) | 10.0 | Decomposed into EditorContent, EditorRightPanel, SingleEditorView, editorSchema, useDiffMode, useEditorFocus, suggestionEnrichment |

+
+Test every acceptance criterion using Playwright against the dev server **before** marking done. This catches 80% of bugs before Brian sees them.

+# 1. Start the dev server (use your worktree port)

+```
+
+**What to test in Playwright:**
+- Every command palette entry from the spec → open `Cmd+K`, type the command name, verify it appears and executes
+- Every keyboard shortcut → send keydown events, verify UI state changes
+- Every UI element described in the spec → verify it renders, is focusable, responds to Tab
+- Edge cases: empty state, long text, rapid keypresses
+
+**Playwright is non-negotiable even if tests pass.** Unit tests verify code; Playwright verifies the user experience in the real browser. Both are required.
+
+> **⚠️ Browser dev server limits**: the dev server uses mock Tauri handlers (`src/mock-tauri.ts`) — file system operations, git commands, and native dialogs are mocked. Test those via `pnpm tauri dev` in Phase 2 if the task touches them.

+**⚠️ QA ≠ tests. QA means using the app as a user.**
+- "Tests pass" is NOT QA. Tests verify code, QA verifies the user experience.
+- The QA comment must describe what you did as a user: "Opened app → Cmd+K → typed 'Trash' → pressed Enter → note disappeared from list → restarted app → note still not visible"
+- Every QA comment must include: the exact keyboard/command palette steps used, what was visible before and after, and any edge case tested.
+- If you cannot test a feature using keyboard only (osascript shortcuts + command palette), the feature is not keyboard-first → QA fails.
+
+**⚠️ Test in a clean environment when the feature depends on state.**
+If a feature involves indexing, fresh installs, first-time setup, or anything that only runs once:
+- **Do not test in the existing dev vault** — it already has the state you're trying to test.
+- **Create a new empty vault** for the test: Cmd+K → "New Vault" (or equivalent), pick a temp folder like `/tmp/test-vault-<slug>`, then test the full first-time flow from scratch.
+- This applies to: search indexing, vault init, getting-started setup, any "on first open" logic.

-- **Test as you go** — write tests alongside code, not after
+- **Update docs/** when changing architecture, abstractions, or significant design (mandatory — see rule below)
 
-## Testing
+## ⛔ DOCS — Keep docs/ in sync with code (mandatory)
+
+After any significant feature change, update the relevant `docs/` files **in the same commit**:
+
+- **`docs/ARCHITECTURE.md`** — stack, system overview, component structure, Tauri commands, data flow, backend modules
+- **`docs/ABSTRACTIONS.md`** — domain models, VaultEntry fields, entity types, key abstractions, integration patterns
+- **`docs/GETTING-STARTED.md`** — directory structure, key files, common tasks, test commands, onboarding
+
+**What counts as "significant":**
+- Adding a new Tauri command or backend module
+- Adding a new major component, hook, or feature (not a bugfix)
+- Changing the data model (VaultEntry fields, new types, new config files)
+- Adding a new integration (API, service, transport)
+- Changing the architecture (new panels, new state management, new build steps)
+
+**How to update:**
+1. Read the relevant doc section before making changes
+2. After your code changes, update the doc to reflect the new state
+3. Commit doc changes together with the code — not in a separate follow-up commit
+
+If unsure whether a change is "significant", err on the side of updating. Stale docs are worse than slightly verbose docs.
+
+## TDD — Red/Green/Refactor (mandatory)
+
+**Always use test-driven development.** No production code without a failing test first.
+
+The loop:
+1. **Red** — write a failing test that describes the behavior you want. Run it, confirm it fails for the right reason.
+2. **Green** — write the minimum code to make the test pass. No more, no less.
+3. **Refactor** — clean up the code (extract, rename, simplify) while keeping tests green.
+4. **Commit** — one red/green/refactor cycle = one atomic commit.
+5. Repeat.
+
+**Why this matters:**
+- Forces you to think about behavior before implementation
+- Produces only code that's actually needed (no speculative abstractions)
+- Tests written first are always behavioral and structure-insensitive by construction
+- Tiny cycles = fast feedback, smaller diffs, easier to review
+
+**For bug fixes:**
+1. Write a failing test that reproduces the bug (this is the regression test)
+2. Fix the bug until the test passes
+3. Commit both together: `fix: [bug] — regression test added`
+
+**For Rust:**
+```bash
+cargo watch -x test   # run tests on every save
+```
+
+**For frontend:**
+```bash
+pnpm test --watch     # run tests on every save
+```
+
+**When to deviate:** Pure UI layout/styling work with no logic is the only exception. Everything else — hooks, utilities, Rust commands, state management — must be TDD.
+
+## Testing (quality bar)
 
 - Unit tests must cover real business logic, not "component renders"
-- Every bug fixed manually → add a regression test
-- Every new feature → new tests for new behavior paths
+- Tests test **behavior** (what the code does), not **structure** (how it does it)
+- Every bug fixed → regression test that would have caught it
+- Every new feature → TDD from the start (see above)
 - `pnpm test:coverage` and `cargo llvm-cov` must pass before committing

+## Vault File Retrocompatibility (mandatory for every feature that adds vault files)
+
+Laputa vaults are long-lived. New app versions must work on existing vaults that were created before a feature existed.
+
+**Rule: never assume a vault file exists. Always auto-create if missing.**
+
+Every feature that depends on a vault file or folder must:
+1. **Auto-bootstrap on vault open** — check if the required file/folder exists; if not, create it with defaults. This must be silent and non-blocking.
+2. **Be idempotent** — creating defaults must be safe to run multiple times (never overwrite user data).
+3. **Expose a repair command** — add a `Cmd+K` command like "Restore Default Themes" or "Repair Vault Config" that explicitly re-creates missing files. Users can run this if something is broken.
+
+**General "Repair Vault" command** — when adding a new vault file dependency, register it with the central repair system so that `Cmd+K → "Repair Vault"` fixes everything in one shot.
+
+**Pattern:**
+```
+on vault open:
+  if file X does not exist → create X with defaults  ← silent auto-repair
+  if file X exists but is malformed → log warning, use defaults (don't crash)
+
+on "Repair Vault" command:
+  for each known vault file/folder:
+    if missing → create with defaults
+    if present → leave untouched (idempotent)
+```
+
+This principle applies to: themes, config files, type files, any `.laputa/` subfolder, or any file Laputa expects to find in a vault.

 bash ~/.openclaw/skills/laputa-qa/scripts/click.sh 400 300   # logical coords
 ```
 
+## Menu Bar Discoverability (mandatory for every new command)
+
+The command palette is powerful but not discoverable — users must already know a command exists to find it. The macOS menu bar is where users discover what an app can do.
+
+**Rule: every significant command palette entry must also appear in the menu bar.**
+
+When adding a new command to the palette:
+1. **Identify the right menu bar group** — File, Edit, View, Note, Vault, or create a new group if needed
+2. **Add a menu item** with the same label as the palette command
+3. **Show the keyboard shortcut** next to the menu item (if one exists)
+4. **If no direct shortcut exists**, still add the menu item — it's discoverable and triggers the same action
+
+The menu bar should be organized around what Laputa does:
+- **File** — new note, open vault, switch vault, close
+- **Edit** — undo, redo, find, note actions (rename, trash, duplicate)
+- **View** — view modes, zoom, sidebar, panels
+- **Note** — note-specific actions (move to trash, archive, properties)
+- **Vault** — vault management (themes, config, repair, sync)
+- **Window / Help** — standard macOS items
+
+**This is a QA requirement:** before marking any task done, verify that every new command palette entry has a corresponding menu bar item.
+
+## Keyboard-First Principle (mandatory for every new feature)
+
+Every feature must be reachable via keyboard. This is both a UX requirement and a QA requirement — Brian tests the native app using keyboard only (osascript key events, no mouse).
+
+**Before marking any task done:**
+- Can the feature be triggered/used without touching the mouse?
+- If it requires clicking a button, add a command palette entry or keyboard shortcut
+- Document the shortcut in the command palette or menu bar
+
+**If you add UI that is only reachable by mouse**, you must also add a keyboard path (command palette entry, shortcut, or Tab-navigable focus). No exceptions.

+Everything lives in the vault as plain text files. Notes, relations, configuration, instructions — all Markdown with YAML frontmatter. No proprietary database, no hidden state. If you can open a terminal, you can read your vault. If you can write Markdown, you can modify it.
+
+### 2. Vault-native configuration
+Laputa configures itself through files inside the vault — the same files you write and read every day. There is no separate "settings app" or admin panel. If you want to change a theme, you edit a note. If you want to give instructions to an AI agent, you write a note. If you want to define a template, you create a note.
+
+This applies to:
+- **`_themes/`** — themes as notes with a YAML block in the body. Edit `_themes/dark.md`, see the colors change in real time.
+- **`AGENTS.md`** — instructions for AI agents. Write what you want them to know about your vault in plain language. They read it before acting.
+- **`_templates/`** — note templates per type. Create `_templates/event.md` and every new event starts from that structure.
+- **`_procedures/`** — recurring tasks as notes with a `schedule` frontmatter field.
+
+The principle: **if it can be expressed in frontmatter + Markdown, it doesn't need a UI**.
+
+### 3. Structure through types, not folders
+Notes have a `type` field. Types determine folders, icons, and colors — but the structure is defined by the data, not the filesystem hierarchy. You can query "all events in February" without knowing anything about folder layout.
+
+Relations between notes are expressed as frontmatter arrays: `people: [Marco, Sara]`. A wikilink `[[Marco]]` in the body navigates to the person note. The graph emerges from the data, not from a separate graph database.
+
+### 4. The file is the interface
+You can use Laputa's UI, or you can open a terminal. Or a text editor. Or Claude Code. They all operate on the same files. There is no difference between "the app" and "the vault" — the vault is the app.
+
+This is why Laputa has an MCP server: external agents get the same tools the in-app AI panel uses. The interface is a convenience, not a requirement.
+
+### 5. Humans and AI as collaborators
+Pulse — the activity feed — shows the history of the vault without distinguishing between human commits and agent commits. That's intentional. Laputa is designed to be a space where you and your AI agents work together, each contributing to the same knowledge base.
+
+The AI doesn't have a separate workspace. It works in yours.
+
+---
+
+## What Laputa is not
+
+- Not a todo app (though you can use it as one)
+- Not a note-taking app that syncs to the cloud (the vault is yours, sync however you want — git, iCloud, rsync)
+- Not a replacement for a terminal (power users will use both)
+- Not trying to abstract away git (git is a feature, not an implementation detail)
+
+---
+
+## The long game
+
+A vault that grows with you for years. Events, people, projects, thoughts — all interconnected, all version-controlled, all accessible to any tool that can read a file.
+
+Ten years from now, your vault should still be readable. Plain text is forever.

 ### Types as Files
 
 Each entity type can have a corresponding **type document** in the `type/` folder (e.g., `type/project.md`, `type/person.md`). Type documents:
 
 - Have `Is A: Type` in their frontmatter
-- Describe what the type means, its expected properties, and how it relates to other types
-- Are navigable entities — they appear in the sidebar under "Types" and can be opened/edited like any other note
+- Define type metadata: icon, color, order, sidebar label, template, sort, view, visibility
+- Are navigable entities — they appear in the sidebar under "Types" and can be opened/edited like any note
 - Serve as the "definition" for their type category
 
+**Type document properties** (read by Rust and used in the UI):
+
+| Property | Type | Description |
+|----------|------|-------------|
+| `icon` | string | Phosphor icon name (kebab-case, e.g., "cooking-pot") |
+| `color` | string | Accent color: red, purple, blue, green, yellow, orange |
+| `order` | number | Sidebar display order (lower = higher priority) |
+| `sidebar_label` | string | Custom label overriding auto-pluralization |
+| `template` | string | Markdown template for new notes of this type |
+| `sort` | string | Default sort: "modified:desc", "title:asc", "property:Priority:asc" |
+| `view` | string | Default view mode: "all", "editor-list", "editor-only" |
+| `visible` | bool | Whether type appears in sidebar (default: true) |
+
 **Type relationship**: When any entry has an `isA` value (e.g., "Project"), the Rust backend automatically adds a `"Type"` entry to its `relationships` map pointing to `[[type/project]]`. This makes the type navigable from the Inspector panel.
 
 **UI behavior**:
-- Clicking a section group header (e.g., "Projects") pins the type document at the top of the NoteList if it exists, with instances listed below
+- Clicking a section group header pins the type document at the top of the NoteList if it exists
 - Viewing a type document in entity view shows an "Instances" group listing all entries of that type
-- The Type field in the Inspector properties panel is rendered as a clickable chip that navigates to the type document

+### Custom Relationships
+
+The Rust parser scans all frontmatter keys for fields containing `[[wikilinks]]`. Any non-standard field with wikilink values is captured in the `relationships` HashMap:

+```yaml
+---
+Topics:
+  - "[[topic/writing]]"
+  - "[[topic/productivity]]"
+Key People:
+  - "[[person/matteo-cellini]]"

+

+
+This enables arbitrary, extensible relationship types without code changes.
+
+### Outgoing Links
+
+All `[[wikilinks]]` in the note body (not frontmatter) are extracted by regex and stored in `outgoingLinks`. Used for backlink detection and relationship graphs.

 ### Title Extraction
 
-Title comes from the first `# Heading` in the markdown body. If none is found, the filename (without `.md`) is used as fallback. This logic lives in `vault.rs:extract_title()`.

+`vault::scan_vault_cached(path)` wraps scanning with git-based caching:

+2. Compares cache version, vault path, and git HEAD commit hash

-Since BlockNote doesn't natively understand `[[wikilinks]]`, content goes through a preprocessing pipeline in `src/utils/wikilinks.ts`:
-
 ```
 Raw markdown
   → splitFrontmatter() → [yaml, body]
   → preProcessWikilinks(body) → replaces [[target]] with Unicode placeholder tokens
   → editor.tryParseMarkdownToBlocks() → BlockNote block tree
-  → injectWikilinks(blocks) → walks tree, replaces placeholder text with wikilink inline content nodes
+  → injectWikilinks(blocks) → walks tree, replaces placeholders with wikilink inline content nodes
   → editor.replaceBlocks()
 ```
 
-Placeholder tokens use `\u2039` (single left-pointing angle quotation mark) and `\u203A` (single right-pointing) to avoid colliding with markdown syntax.
+Placeholder tokens use `\u2039` and `\u203A` to avoid colliding with markdown syntax.
+
+### BlockNote-to-Markdown Pipeline (Save)
+
+```
+BlockNote blocks
+  → editor.blocksToMarkdownLossy()
+  → postProcessWikilinks() → restore [[target]] syntax from wikilink nodes
+  → prepend frontmatter yaml
+  → invoke('save_note_content', { path, content })
+```
 
 ### Wikilink Navigation
 
 Two navigation mechanisms:
 
-1. **Click handler**: A DOM event listener on `.editor__blocknote-container` catches clicks on `.wikilink` elements and calls `onNavigateWikilink(target)`.
+1. **Click handler**: DOM event listener on `.editor__blocknote-container` catches clicks on `.wikilink` elements → `onNavigateWikilink(target)`.
+2. **Suggestion menu**: Typing `[[` triggers `SuggestionMenuController` with filtered vault entries.
 
-2. **Suggestion menu**: Typing `[[` triggers BlockNote's `SuggestionMenuController`, which shows a filtered list of all vault entries. Selecting one inserts a wikilink inline content node.
+Wikilink resolution (`useNoteActions`) uses fuzzy matching: exact title → alias → path stem → filename stem → slug-to-words.
 
-Wikilink resolution in `useNoteActions.handleNavigateWikilink()` uses fuzzy matching:
-- Exact title match
-- Alias match
-- Path stem match (e.g., `person/matteo-cellini`)
-- Filename stem match
-- Slug-to-words match (e.g., `matteo-cellini` → `matteo cellini`)
+### Raw Editor Mode
+
+Toggle via Cmd+K → "Raw Editor" or breadcrumb bar button. Uses CodeMirror 6 (`useCodeMirror` hook) to edit the raw markdown + frontmatter directly. Changes saved via the same `save_note_content` command.
 
 ## Theme System
 
 See [THEMING.md](./THEMING.md) for the full theme system documentation.
 
-In brief: `src/theme.json` defines editor typography and styling as nested JSON. The `useEditorTheme` hook flattens it into CSS custom properties that are applied as inline styles on the BlockNote container.
+### Overview
+
+Two-layer theming:
+1. **Global CSS variables** (`src/index.css`): App-wide colors via `:root`, bridged to Tailwind v4
+2. **Editor theme** (`src/theme.json`): BlockNote typography, flattened to CSS vars by `useEditorTheme`
+
+### Vault-Based Themes
+
+Themes are markdown notes in `theme/` with `Is A: Theme` frontmatter. Each property becomes a CSS variable with `--` prefix.
+
+```yaml
+---
+Is A: Theme
+Description: Light theme with warm, paper-like tones
+background: "#FFFFFF"
+foreground: "#37352F"
+accent-blue: "#155DFF"
+editor-font-size: 16
+editor-line-height: 1.5
+---
+```
+
+### ThemeManager
+
+`useThemeManager` hook manages the theme lifecycle:
+
+```typescript
+interface ThemeManager {
+  themes: ThemeFile[]
+  activeThemeId: string | null
+  activeTheme: ThemeFile | null
+  isDark: boolean
+  switchTheme(themeId: string): Promise<void>
+  createTheme(name?: string): Promise<string>
+  reloadThemes(): Promise<void>
+  updateThemeProperty(key: string, value: string): Promise<void>
+}
+```
+
+- Detects dark backgrounds via luminance calculation → sets `color-scheme` and `data-theme-mode`
+- Live preview: re-applies when active theme note is saved
+- Three built-in themes: Default (light), Dark (deep navy), Minimal (high contrast)
+- Legacy JSON themes (`_themes/*.json`) supported for backward compatibility
+
+### Theme Property Editor
+
+`ThemePropertyEditor` component provides an interactive UI for editing theme properties. Uses `themeSchema.ts` to determine input types (color picker, number slider, text field) based on property names and values.
 
 ## Inspector Abstraction
 
-The Inspector panel (`src/components/Inspector.tsx`) is composed of four sub-panels:
+The Inspector panel (`src/components/Inspector.tsx`) is composed of sub-panels:
 
-1. **DynamicPropertiesPanel** (`src/components/DynamicPropertiesPanel.tsx`): Renders frontmatter as editable key-value pairs with two distinct sections:
-   - **Editable properties** (top): frontmatter fields the user can modify — shown with interactive hover styling (`hover:bg-muted`), cursor pointer, and click-to-edit. Includes Type badge, Status pill, boolean toggles, array tag pills, and text fields.
-   - **Info section** (bottom, separated by border): read-only derived metadata — Modified, Created, Words, File Size. Uses muted text color (`--text-muted`) with no hover states or click interaction. These fields are computed from file metadata and content, not from frontmatter.
-   - Keys in `SKIP_KEYS` (`aliases`, `notion_id`, `workspace`, `is_a`, `Is A`) are hidden from the editable section since they are either internal or already displayed elsewhere (e.g., `is_a` is shown via the TypeRow badge).
-2. **Relationships**: Shows `belongs_to` and `related_to` wikilinks as clickable chips.
-3. **Backlinks**: Scans `allContent` for notes that reference the current note via `[[title]]` or `[[path]]`.
-4. **Git History**: Shows the last few commits from `gitHistory` state.
+1. **DynamicPropertiesPanel** (`src/components/DynamicPropertiesPanel.tsx`): Renders frontmatter as editable key-value pairs:
+   - **Editable properties** (top): Type badge, Status pill with dropdown, boolean toggles, array tag pills, text fields. Click-to-edit interaction.
+   - **Info section** (bottom, separated by border): Read-only derived metadata — Modified, Created, Words, File Size. Uses muted styling with no interaction.
+   - Keys in `SKIP_KEYS` (`aliases`, `notion_id`, `workspace`, `is_a`, `Is A`) are hidden from the editable section.
 
-Frontmatter parsing on the TypeScript side is handled by `src/utils/frontmatter.ts:parseFrontmatter()`, a lightweight YAML parser that handles strings, booleans, inline arrays, and multi-line lists.
+2. **RelationshipsPanel**: Shows `belongs_to`, `related_to`, and all custom relationship fields as clickable wikilink chips.
+
+3. **BacklinksPanel**: Scans `allContent` for notes that reference the current note via `[[title]]` or `[[path]]`.
+
+4. **GitHistoryPanel**: Shows recent commits from file history with relative timestamps.
+
+## Search & Indexing
+
+### Search Modes
+
+```typescript
+type SearchMode = 'keyword' | 'semantic' | 'hybrid'
+
+interface SearchResult {
+  title: string
+  path: string
+  snippet: string
+  score: number
+}
+
+interface SearchResponse {
+  results: SearchResult[]
+  elapsedMs: number
+}
+```
+
+### Search Integration
+
+`SearchPanel` component provides the search UI:
+- Mode selector (keyword/semantic/hybrid)
+- Real-time results as user types
+- Click result to open note in editor
+- Shows relevance score and snippet
+
+### Indexing
+
+Managed by `useIndexing` hook:
+- Checks index status on vault load
+- Two-phase indexing: scanning (parse files) → embedding (generate vectors)
+- Progress streamed via Tauri events
+- Incremental updates after git sync
+- Metadata persisted in `.laputa-index.json`
+
+## Vault Management
+
+### Vault Switching
+
+`useVaultSwitcher` hook manages multiple vaults:
+- Persists vault list to `~/.config/com.laputa.app/vaults.json`
+- Switching closes all tabs and resets sidebar
+- Supports adding, removing, hiding/restoring vaults
+- Default vault: Getting Started demo vault
+
+### Vault Config
+
+Per-vault settings stored in `config/ui.config.md`:
+- Editable as a normal note (YAML frontmatter)
+- Managed by `useVaultConfig` hook and `vaultConfigStore`
+- Settings: zoom, view mode, tag colors, status colors, property display modes
+- One-time migration from localStorage (`configMigration.ts`)
+
+### Getting Started / Onboarding
+
+`useOnboarding` hook detects first launch:
+- If vault path doesn't exist → show `WelcomeScreen`
+- User can create Getting Started vault or open existing folder
+- Welcome state tracked in localStorage (`laputa_welcome_dismissed`)
+
+### GitHub Integration
+
+Device Authorization Flow for GitHub-backed vaults:
+- `GitHubDeviceFlow` component handles OAuth
+- `GitHubVaultModal` for cloning existing repos or creating new ones
+- Token persisted in app settings for future git operations
+- `SettingsPanel` shows connection status with disconnect option
+
+## Settings
+
+App-level settings persisted at `~/.config/com.laputa.app/settings.json`:
+
+```typescript
+interface Settings {
+  anthropic_key: string | null
+  openai_key: string | null
+  google_key: string | null
+  github_token: string | null
+  github_username: string | null
+  auto_pull_interval_minutes: number | null
+}
+```
+
+Managed by `useSettings` hook and `SettingsPanel` component.

-## AI Chat System
+## AI System
 
-### Architecture
+Laputa has two AI interfaces with distinct architectures:
 
-The AI chat feature has three layers:
+### AI Chat (AIChatPanel)
+
+Simple chat mode — no tool execution, streaming text responses.
 
 1. **Frontend** (`AIChatPanel` + `useAIChat` hook) — UI and state management
 2. **API Proxy** (Vite middleware in dev, Rust `ai_chat` command in Tauri) — routes to Anthropic
-3. **MCP Server** (`mcp-server/`) — vault operation tools for AI assistants
+3. **Context picker** — selected notes sent as system context with token estimation
 
-### Data Flow
+### AI Agent (AiPanel)
+
+Full agent mode — spawns Claude CLI as a subprocess with tool access and MCP vault integration.
+
+1. **Frontend** (`AiPanel` + `useAiAgent` hook) — streaming UI with reasoning blocks, tool action cards, and response display
+2. **Backend** (`claude_cli.rs`) — spawns `claude` binary with `--output-format stream-json`, parses NDJSON events
+3. **MCP Integration** — passes vault MCP config via `--mcp-config` flag so the agent can search, read, and modify vault notes
+
+#### Agent Event Flow
 
 ```
-User types message in AIChatPanel
-  → useAIChat.sendMessage(text)
-    → buildSystemPrompt(contextNotes, allContent, model)
-      → Assembles selected notes as system context
-      → Estimates tokens, truncates if needed
-    → streamChat(messages, systemPrompt, model, callbacks)
-      → POST /api/ai/chat (Vite proxy → Anthropic API)
-      → SSE stream parsed, chunks dispatched to onChunk callback
-      → UI updates in real-time as tokens arrive
-    → On completion: message added to conversation history
+User sends message in AiPanel
+  → useAiAgent.sendMessage(text, references)
+    → buildContextSnapshot(activeNote, linkedNotes, openTabs)
+    → invoke('stream_claude_agent', { message, systemPrompt, vaultPath })
+      → Rust spawns: claude -p <msg> --output-format stream-json --mcp-config <json>
+      → NDJSON lines parsed into ClaudeStreamEvent variants:
+          Init, TextDelta, ThinkingDelta, ToolStart, ToolDone, Result, Error, Done
+      → Events emitted via Tauri: app_handle.emit("claude-agent-stream", &event)
+    → Frontend listener routes events:
+        onText → accumulate response (revealed on Done)
+        onThinking → show reasoning block (collapsed on first text)
+        onToolStart → add AiActionCard with spinner
+        onToolDone → update card with output
+        onDone → reveal full response, detect file operations

+#### File Operation Detection
 
-The context picker controls which notes are sent to the AI as context:
+When the agent writes or edits vault files, `useAiAgent` detects this from tool inputs (Write/Edit tool JSON) and calls `onFileCreated` or `onFileModified` callbacks to trigger vault reload.
 
-- **Current note** is auto-added when the panel opens
-- **Add button** opens a search dropdown to select additional notes
-- **Token estimation** shows approximate context size (~4 chars/token)
-- **Truncation** kicks in when context exceeds 60% of model limit (108k tokens)
-- Context pills show selected notes with remove buttons
+### Context Building
 
-### API Key Management
+Both AI modes use context from the active note and linked entries. The agent panel (`ai-context.ts`) builds a structured JSON snapshot:
 
-- Stored in `localStorage` under key `laputa:anthropic-api-key`
-- Configurable via the key icon in the AI Chat header
-- When no key is set, falls back to mock responses for testing
+```json
+{
+  "activeNote": { "path", "title", "type", "frontmatter", "content" },
+  "linkedNotes": [{ "path", "title", "content" }],
+  "openTabs": [{ "title", "snippet" }],
+  "vaultMetadata": { "noteTypes", "stats", "filter" },
+  "references": [{ "title", "path", "type" }]
+}
+```
 
-### Models
+Token budget: 60% of 180k context limit (~108k tokens max). Active note gets priority, then linked notes, then truncation.

+### API Key Management
 
-The MCP server (`mcp-server/`) exposes vault operations as tools:
+- Stored in app settings (`~/.config/com.laputa.app/settings.json`) under `anthropic_key`
+- Configurable via Settings panel (also supports `openai_key`, `google_key`)
+- Claude CLI (agent mode) uses its own authentication — no API key needed
 
-| Tool | Description |
-|------|-------------|
-| `open_note` | Open and read a note by path |
-| `read_note` | Read note content (alias) |
-| `create_note` | Create new note with frontmatter |
-| `search_notes` | Search by title or content |
-| `append_to_note` | Append text to a note |
+## MCP Server

+| `list_notes` | `[type_filter], [sort]` | List all notes, optionally filtered by type |
+| `vault_context` | — | Get vault summary: entity types + 20 recent notes + configFiles |
+| `ui_open_note` | `path` | Open a note in the Laputa UI editor |
+| `ui_open_tab` | `path` | Open a note in a new UI tab |
+| `ui_highlight` | `element, [path]` | Highlight a UI element (editor, tab, properties, notelist) |
+| `ui_set_filter` | `type` | Set the sidebar filter to a specific type |
+
+### Transports
+
+- **stdio** — standard MCP transport for Claude Code / Cursor (`node mcp-server/index.js`)
+- **WebSocket** — live bridge for Laputa app integration:
+  - Port **9710**: Tool bridge — AI/Claude clients call vault tools here
+  - Port **9711**: UI bridge — Frontend listens for UI action broadcasts from MCP tools
+
+### Auto-Registration
+
+On app startup, Laputa automatically registers itself as an MCP server in:
+- `~/.claude/mcp.json` (Claude Code)
+- `~/.cursor/mcp.json` (Cursor)
+
+Registration is non-destructive (additive, preserves other servers) and uses `upsert` semantics. The `useMcpStatus` hook tracks registration state (`checking | installed | not_installed | no_claude_cli`).

 ### WebSocket Bridge
 
-The WebSocket bridge (`useMcpBridge` hook) enables real-time vault operations from the frontend:
+The WebSocket bridge enables real-time vault operations from both the frontend and external AI clients:
 
 ```
 Frontend (useMcpBridge) ←→ ws://localhost:9710 ←→ ws-bridge.js ←→ vault.js
+MCP stdio tools         ←→ ws://localhost:9711 ←→ Frontend UI actions (useAiActivity)
 ```
 
-Protocol: JSON-RPC-like with `{id, tool, args}` requests and `{id, result}` responses.
+**Tool bridge protocol** (port 9710):
+- Request: `{ "id": "req-1", "tool": "search_notes", "args": { "query": "test" } }`
+- Response: `{ "id": "req-1", "result": { ... } }`
 
-### Rust Backend (Tauri)
+**UI bridge protocol** (port 9711):
+- Broadcast: `{ "type": "ui_action", "action": "open_note", "path": "..." }`
+- `useAiActivity` hook receives these and applies them (highlight with 800ms feedback, open note, set filter, etc.)
 
-The `ai_chat` Tauri command (`src-tauri/src/ai_chat.rs`) provides a non-streaming alternative:
-- Uses `reqwest` to call the Anthropic Messages API directly
-- API key from `ANTHROPIC_API_KEY` environment variable
-- Returns full response (not streamed)
-- Used in production Tauri builds where Vite proxy is unavailable
+### Rust MCP Module
 
-### Files
+`src-tauri/src/mcp.rs` manages the MCP server lifecycle:
 
-| File | Purpose |
-|------|---------|
-| `src/components/AIChatPanel.tsx` | Main UI: context bar, messages, input, quick actions |
-| `src/hooks/useAIChat.ts` | Chat state: messages, streaming, send/retry/clear |
-| `src/hooks/useMcpBridge.ts` | WebSocket client for MCP vault tool calls |
-| `src/utils/ai-chat.ts` | API client, token estimation, context builder |
-| `src-tauri/src/ai_chat.rs` | Rust Anthropic API client (non-streaming) |
-| `mcp-server/index.js` | MCP server entry (stdio transport) |
-| `mcp-server/vault.js` | Vault file operations |
-| `mcp-server/ws-bridge.js` | WebSocket bridge server |
+| Function | Purpose |
+|----------|---------|
+| `spawn_ws_bridge(vault_path)` | Spawns `ws-bridge.js` as child process with VAULT_PATH env |
+| `register_mcp(vault_path)` | Writes Laputa entry to Claude Code and Cursor MCP configs |
+| `upsert_mcp_config(path, entry)` | Atomic config file update (create/merge, preserves others) |
+
+The `WsBridgeChild` state wrapper in `lib.rs` ensures the bridge process is killed on app exit via `RunEvent::Exit` handler.
+
+## Search & Indexing
+
+### Search Engine
+
+Search uses the external `qmd` binary (semantic search engine) with three modes:
+
+| Mode | Command | Description |
+|------|---------|-------------|
+| `keyword` | `qmd search` | Term matching (default) |
+| `semantic` | `qmd vsearch` | Vector similarity search |
+| `hybrid` | `qmd query` | Combined keyword + semantic |
+
+### Indexing Flow
+
+```
+Vault opened
+  → check_index_status() → parse qmd status output
+  → if stale or missing:
+    → start_indexing() (two phases):
+        Phase 1 (Scanning): qmd update — scan all .md files
+        Phase 2 (Embedding): qmd embed — generate vector embeddings
+    → Progress streamed via Tauri "indexing-progress" event
+    → Metadata saved to .laputa-index.json (last_indexed_commit, timestamp)
+  → run_incremental_update() for subsequent changes
+```
+
+Embedding failure is non-fatal — keyword search still works.
+
+### qmd Binary Resolution
+
+1. Bundled macOS app resource: `<app>/Contents/Resources/qmd/qmd`
+2. Dev mode: `CARGO_MANIFEST_DIR/resources/qmd/qmd`
+3. System locations: `~/.bun/bin/qmd`, `/usr/local/bin/qmd`, `/opt/homebrew/bin/qmd`
+4. PATH lookup via `which qmd`
+5. Auto-install via `bun install -g qmd` if missing
+
+## Vault Cache System
+
+The vault cache (`src-tauri/src/vault/cache.rs`) accelerates vault scanning using git-based incremental updates.
+
+### Cache File
+
+`.laputa-cache.json` at vault root. Stores: vault path, git HEAD commit hash, all VaultEntry objects. Version: v5 (bumped on VaultEntry field changes to force full rescan).
+
+### Three Cache Strategies
+
+1. **Same Commit (Cache Hit)**: Git HEAD matches cached hash → only re-parse uncommitted changed files via `git status --porcelain`
+2. **Different Commit (Incremental Update)**: Uses `git diff <old>..<new> --name-only` to find changed files + uncommitted changes → selective re-parse
+3. **No Cache / Corrupt Cache (Full Scan)**: Recursive `walkdir` of all `.md` files → full parse
+
+Cache auto-excludes itself from git via `.git/info/exclude`.
+
+## Theme System
+
+See [THEMING.md](./THEMING.md) for the full theme system documentation.
+
+### Two-Layer Architecture
+
+1. **Global CSS variables** (`src/index.css`): App-wide colors, borders, backgrounds. Bridged to Tailwind v4 via `@theme inline`.
+2. **Editor theme** (`src/theme.json`): BlockNote-specific typography. Flattened to CSS vars by `useEditorTheme`.
+
+### Vault-Based Themes
+
+Themes are markdown notes in the `theme/` folder with `Is A: Theme` frontmatter. Each frontmatter property becomes a CSS variable. Managed by `useThemeManager` hook and the `src-tauri/src/theme/` Rust module (create, seed, defaults).
+
+- **Vault settings**: `.laputa/settings.json` stores the active theme reference
+- **Legacy support**: `_themes/*.json` files still supported for backward compatibility
+- **Built-in themes**: Default (light), Dark, Minimal — auto-seeded on vault open
+- **Live preview**: Re-applies when the active theme note is saved
+
+## Vault Management
+
+### Vault List
+
+Persisted at `~/.config/com.laputa.app/vaults.json`:
+```json
+{
+  "vaults": [{ "label": "My Vault", "path": "/path/to/vault" }],
+  "active_vault": "/path/to/vault",
+  "hidden_defaults": []
+}
+```
+
+Managed by `useVaultSwitcher` hook. Switching vaults closes all tabs and resets sidebar.
+
+### Vault Config
+
+Per-vault UI settings stored in `config/ui.config.md` (YAML frontmatter in a markdown note):
+- `zoom`: Float zoom level (0.8–1.5)
+- `view_mode`: "all" | "editor-list" | "editor-only"
+- `tag_colors`, `status_colors`: Custom color overrides
+- `property_display_modes`: Property display preferences
+
+### Getting Started Vault
+
+On first launch, `useOnboarding` checks if the default vault exists. If not, shows `WelcomeScreen` with two options:
+- **Create Getting Started vault** → calls `create_getting_started_vault()` Tauri command
+- **Open an existing folder** → system file picker
+
+### GitHub OAuth Integration
+
+Implements GitHub Device Authorization Flow for cloning/creating GitHub-backed vaults.
+
+**Flow:**
+1. User clicks "Login with GitHub" in Settings panel
+2. `github_device_flow_start()` returns a user code + verification URL
+3. User authorizes at `github.com/login/device`
+4. App polls `github_device_flow_poll()` until authorized
+5. Token stored in `~/.config/com.laputa.app/settings.json`
+
+**Vault operations:**
+- `GitHubVaultModal`: Clone existing repo or create new private/public repo
+- `clone_repo()`: Clones with token-injected HTTPS URL
+- Token persists for future git push/pull operations
+
+## Pulse View
+
+`PulseView` is a git activity feed that replaces the NoteList when the Pulse filter is selected.
+
+- Groups commits by day ("Today", "Yesterday", or full date)
+- Shows commit message, short hash, timestamp, and changed files
+- Files have status icons (added/modified/deleted) and are clickable to open in editor
+- Links to GitHub commits when `githubUrl` is available
+- Infinite scroll pagination (20 commits per page) via Intersection Observer
+
+Backend: `get_vault_pulse` Tauri command parses `git log` with `--name-status`.

-### Universal Binary
-
-macOS builds produce both `aarch64-apple-darwin` and `x86_64-apple-darwin` in parallel. The release job merges them with `lipo` — copying the arm64 `.app` as the base and replacing only the main executable with a universal fat binary. The per-arch updater tarballs are also uploaded so the Tauri updater downloads only the relevant architecture (smaller download).
-
-### Updater Endpoint
-
-The Tauri updater plugin is configured to fetch:
-```
-https://github.com/refactoringhq/laputa-app/releases/latest/download/latest.json
-```
-
-This JSON manifest contains `version`, `pub_date`, `notes`, and per-platform entries (`darwin-aarch64`, `darwin-x86_64`) with `url` and `signature` fields. The updater compares the manifest version against the running app version, downloads the matching platform artifact, verifies the signature, and installs it.

 ## Common Tasks
 
 ### Add a new Tauri command
 
-1. Write the Rust function in `vault.rs`, `git.rs`, or a new module
-2. Add `#[tauri::command]` wrapper in `lib.rs`
+1. Write the Rust function in the appropriate module (`vault/`, `git/`, etc.)
+2. Add a command handler in `commands.rs`
 3. Register it in the `generate_handler![]` macro in `lib.rs`
 4. Call it from the frontend via `invoke()` in the appropriate hook
 5. Add a mock handler in `mock-tauri.ts`
@@ -217,6 +332,25 @@ npx playwright test e2e/screenshot.spec.ts
 ### Add a new entity type
 
 1. Create the folder in the vault (e.g., `~/Laputa/mytype/`)
-2. Add the folder → type mapping in `vault.rs:parse_md_file()` (the `match` on folder names)
-3. The sidebar section groups are defined as `SECTION_GROUPS` in `Sidebar.tsx` — add it there
-4. Update `CreateNoteDialog.tsx` type options if users should be able to create it
+2. Create a type document: `type/mytype.md` with `Is A: Type` frontmatter (icon, color, order, etc.)
+3. The sidebar section groups are auto-generated from type documents — no code change needed if `visible: true`
+4. Update `CreateNoteDialog.tsx` type options if users should be able to create it from the dialog
+
+### Add a command palette entry
+
+1. Register the command in `useAppCommands.ts` via the command registry
+2. Add a corresponding menu bar item in `menu.rs` for discoverability
+3. If it has a keyboard shortcut, register it in `useAppKeyboard.ts`
+
+### Add or modify a theme
+
+1. **Vault-based** (preferred): Create/edit a markdown note in `theme/` with `Is A: Theme` frontmatter
+2. **Programmatic**: Edit defaults in `src-tauri/src/theme/defaults.rs`
+3. See `docs/THEMING.md` for the full property reference
+
+### Work with the AI agent
+
+1. **Agent system prompt**: Edit `src/utils/ai-agent.ts` (inline system prompt string)
+2. **Context building**: Edit `src/utils/ai-context.ts` for what data is sent to the agent
+3. **Tool action display**: Edit `src/components/AiActionCard.tsx`
+4. **Claude CLI arguments**: Edit `src-tauri/src/claude_cli.rs` (`run_agent_stream()`)
