+
+## Architecture Overview
+
+Adiuva is a local-first Electron desktop app. The three Electron processes communicate via a custom tRPC↔IPC bridge (the public `electron-trpc` package is incompatible with tRPC v11, so a custom implementation is used).
+
+### Process Boundaries
+
+```
+Renderer (React)  ──ipcLink──►  Preload (contextBridge)  ──IPC──►  Main (tRPC router + SQLite)
+```
+
+1. **Main process** (`src/main/`) — Node.js, owns the database and all business logic
+   - `index.ts` — Window creation, app lifecycle
+   - `ipc.ts` — Custom handler that bridges `ipcMain` to tRPC procedures
+   - `router/index.ts` — All tRPC routers (clients, projects, tasks, checkpoints, notes, settings, ai)
+   - `db/index.ts` — Drizzle + better-sqlite3, WAL mode, singleton `getDb()`
+   - `db/schema.ts` — All table definitions (clients, projects, tasks, checkpoints, notes)
+   - `store.ts` — electron-store for persistent UI settings (e.g., `sidebarCollapsed`)
+
+2. **Preload** (`src/preload/trpc.ts`) — Exposes `window.electronTRPC` with `sendMessage()` / `onMessage()`
+
+3. **Renderer** (`src/renderer/`) — React 19, never accesses Node APIs directly
+   - `lib/ipcLink.ts` — Custom TRPCLink that routes calls through `window.electronTRPC`
+   - `lib/trpc.ts` — `createTRPCReact<AppRouter>()` typed client
+   - `index.tsx` — QueryClient + tRPC + Router providers
+   - All data access is through `trpc.*.*useQuery()` / `trpc.*.*.useMutation()`
+
+### Routing
+
+File-based routing via TanStack Router. Add a file to `src/renderer/routes/` and the route tree (`src/renderer/routeTree.gen.ts`) is auto-regenerated by the Vite plugin on next `npm start`. Routes:
+- `__root.tsx` — Root layout wrapping everything in `AppShell`
+- `index.tsx`, `tasks.tsx`, `timeline.tsx`, `projects.tsx`
+
+### Database
+
+Schema lives in `src/main/db/schema.ts`. Migrations are in `src/main/db/migrations/`. The DB is created in Electron's `userData` directory as `adiuva.db`. On startup, `initDb()` runs non-destructive migrations (CREATE TABLE IF NOT EXISTS).
+
+To add a new table or column: edit `schema.ts`, run `drizzle-kit generate`, then `drizzle-kit push` (dev) or commit the migration file.
+
+### Adding a New Feature (end-to-end pattern)
+
+1. **Schema** — Add table/columns to `src/main/db/schema.ts`
+2. **Router** — Add a tRPC sub-router in `src/main/router/index.ts`, merge it into `appRouter`
+3. **Types** — `AppRouter` is exported from `src/main/router/index.ts` and imported in `src/renderer/lib/trpc.ts` — types flow automatically
+4. **UI** — Create components under `src/renderer/components/<feature>/`, use `trpc.*.*useQuery()` for data
+
+### AI Subsystem (`src/main/ai/`)
+
+LangGraph-based agentic system with pluggable LLM providers (OpenAI, Anthropic, GitHub Copilot).
+
+**Orchestrator** (`orchestrator.ts`): Classifies user intent → routes to one of three specialist agents:
+- **Project agent** — project-scoped Q&A with tools: `read_project_notes`, `add_task`, `get_summary`, `suggest_checkpoints`, `suggest_tasks`
+- **Knowledge agent** — cross-project semantic search via `vector_search_all`
+- **General agent** — workspace-wide `add_task`
+
+Tool-calling strategy differs by provider: OpenAI/Anthropic use LangChain `bindTools()` + ToolMessage loop (max 5 iterations); Copilot uses SDK-native tools (loop handled internally).
+
+**Streaming**: Orchestrator calls `sendStreamChunk(sender, token, done)` over IPC channel `'ai:stream'`. Renderer subscribes via `window.electronAI.onStreamChunk()` in `AIChatPanel.tsx`. `<tool_call>` blocks are filtered before sending to renderer.
+
+**Provider factory** (`llm.ts`): `gpt-4o-mini` (OpenAI), `claude-sonnet-4-20250514` (Anthropic), or ChatCopilot wrapper — all with `temperature: 0.3` and streaming enabled.
+
+**Token storage** (`token.ts`) — two-tier fallback:
+1. electron-store + `safeStorage` — encrypted at rest (preferred)
+2. Plain electron-store — last resort (e.g. WSL with no keyring)
+
+**AI approval pattern**: Tasks and checkpoints have `isAiSuggested` (bool) and `isApproved` (bool) columns. AI-suggested items appear in the UI pending user approval before being treated as real records.
+
+### Vector Embeddings (`src/main/db/vectordb.ts`)
+
+LanceDB stored in `{userData}/vectors/`. Table schema: `{ id, projectId, content, vector }`. Vectors are 1536-dimensional (`text-embedding-3-small`). Embeddings use a priority chain: Copilot CLI token → OpenAI token.
+
+- Note create/update fires `upsertNoteEmbedding()` (fire-and-forget, errors swallowed)
+- `migrateNotesIfNeeded()` backfills existing notes on first startup
+- `searchNotes(query, limit=5)` is called by the Knowledge agent tool
+
+### Key Config Notes
+
+- Vite configs use `.mts` extension (not `.ts`) to avoid ESM/CJS conflicts with electron-forge's externalize-deps plugin
+- `@/*` path alias resolves to `src/renderer/*` (TypeScript + Vite + shadcn/ui all share this alias)
+- shadcn/ui style: **new-york**, base color: **neutral**
+- Icons: **lucide-react** throughout — do not introduce other icon libraries
+- Tailwind 4 (not 3) — use CSS variable theming via `globals.css`, not `tailwind.config.js`
+- Notes use Milkdown (`@milkdown/crepe`) as the markdown editor (`src/renderer/components/notes/MilkdownEditor.tsx`)
+- Routes: `index`, `tasks`, `timeline`, `projects`, `notes.$noteId` (note ID is a URL param)
+
+## Design Context
+
+### Users
+Freelancers and solo professionals managing their own client work — projects, tasks, notes, and timelines. They work alone and need a single workspace that keeps everything organized without the overhead of enterprise tools. The AI assistant is a force multiplier, helping them stay on top of their workload.
+
+### Brand Personality
+**Calm, intelligent, warm.** Adiuva is a thoughtful companion, not a flashy tool. It should feel like a well-organized desk — everything in its place, nothing competing for attention. The tone is confident and understated, never loud or gamified.
+
+### Aesthetic Direction
+- **Visual tone**: Editorial, premium, content-first. Inspired by Notion's clean typography and warm neutrals, but with a distinct identity through the warm pinkish-white canvas and golden yellow accent
+- **Light mode**: Soft and warm — pinkish-white (`#f4edf3`) canvas, golden yellow (`#fbc881`) primary, slate blue-gray (`#8a8ea9`) secondary, dusty lavender borders (`#c8c3cd`)
+- **Dark mode**: Stark monochrome — near-black canvas (`#0c0c0c`), crisp white text, dark gray surfaces (`#323232`). No color accent; primary is pure white
+- **Typography**: Geist (geometric sans-serif) at 400/500/600. Tight tracking on large headings (`-1px`). Body at `text-sm`, metadata at `text-xs`
+- **Corners**: 10px base radius, consistently rounded. Chat elements use `rounded-2xl`
+- **Signature effects**: Glassmorphism on AI inputs/floating chat (`backdrop-blur-xl`, transparency). Spring physics animations (stiffness 400, damping 30). Subtle scale-and-fade transitions
+- **Anti-references**: No gamification (badges, streaks, confetti). No corporate/enterprise density. Keep it mature and professional
+
+### Design Principles
+
+1. **Clarity over cleverness** — Every element should communicate its purpose instantly. Prefer clear hierarchy and whitespace over decorative flourish. Information density should feel comfortable, not cramped.
+
+2. **AI as quiet partner** — The AI is deeply integrated (floating chat, suggestions) but never intrusive. AI-suggested items use dashed borders to signal "pending." The Sparkles icon is the consistent AI identity marker.
+
+3. **Warmth in restraint** — The palette is deliberately warm (pinkish whites, golden yellows) to feel approachable without being playful. Dark mode trades warmth for focus. Let the content breathe.
+
+4. **Motion with purpose** — Spring physics and glassmorphism create a sense of physicality and depth. Animations should feel natural and responsive, never decorative or slow. Every transition should reinforce spatial relationships.
+
+5. **Confidence through consistency** — Use the established token system (CSS variables, shadcn/ui primitives, Geist font). The user should feel in control — predictable patterns, keyboard-first interactions, no surprises.

-# Ralph Agent Instructions
-
-You are an autonomous coding agent working on a software project.
-
-## Your Task
-
-1. Read the full app PRD at `prd-main.md` (in the same directory as this file)
-2. Read the PRD at `prd.json` (in the same directory as this file)
-3. Read the progress log at `progress.txt` (check Codebase Patterns section first)
-4. Check you're on the correct branch from PRD `branchName`. If not, check it out or create from main.
-5. Pick the **highest priority** user story where `passes: false`
-6. Implement that single user story
-7. Run quality checks (e.g., typecheck, lint, test - use whatever your project requires)
-8. Update CLAUDE.md files if you discover reusable patterns (see below)
-9. If checks pass, commit ALL changes with message: `feat: [Story ID] - [Story Title]`
-10. Update the PRD to set `passes: true` for the completed story
-11. Append your progress to `progress.txt`
-
-## Progress Report Format
-
-APPEND to progress.txt (never replace, always append):
-```
-## [Date/Time] - [Story ID]
-- What was implemented
-- Files changed
-- **Learnings for future iterations:**
-  - Patterns discovered (e.g., "this codebase uses X for Y")
-  - Gotchas encountered (e.g., "don't forget to update Z when changing W")
-  - Useful context (e.g., "the evaluation panel is in component X")
----
-```
-
-The learnings section is critical - it helps future iterations avoid repeating mistakes and understand the codebase better.
-
-## Consolidate Patterns
-
-If you discover a **reusable pattern** that future iterations should know, add it to the `## Codebase Patterns` section at the TOP of progress.txt (create it if it doesn't exist). This section should consolidate the most important learnings:
-
-```
-## Codebase Patterns
-- Example: Use `sql<number>` template for aggregations
-- Example: Always use `IF NOT EXISTS` for migrations
-- Example: Export types from actions.ts for UI components
-```
-
-Only add patterns that are **general and reusable**, not story-specific details.
-
-## Update CLAUDE.md Files
-
-Before committing, check if any edited files have learnings worth preserving in nearby CLAUDE.md files:
-
-1. **Identify directories with edited files** - Look at which directories you modified
-2. **Check for existing CLAUDE.md** - Look for CLAUDE.md in those directories or parent directories
-3. **Add valuable learnings** - If you discovered something future developers/agents should know:
-   - API patterns or conventions specific to that module
-   - Gotchas or non-obvious requirements
-   - Dependencies between files
-   - Testing approaches for that area
-   - Configuration or environment requirements
-
-**Examples of good CLAUDE.md additions:**
-- "When modifying X, also update Y to keep them in sync"
-- "This module uses pattern Z for all API calls"
-- "Tests require the dev server running on PORT 3000"
-- "Field names must match the template exactly"
-
-**Do NOT add:**
-- Story-specific implementation details
-- Temporary debugging notes
-- Information already in progress.txt
-
-Only update CLAUDE.md if you have **genuinely reusable knowledge** that would help future work in that directory.
-
-## Quality Requirements
-
-- ALL commits must pass your project's quality checks (typecheck, lint, test)
-- Do NOT commit broken code
-- Keep changes focused and minimal
-- Follow existing code patterns
-
-## Browser Testing (If Available)
-
-For any story that changes UI, verify it works in the browser if you have browser testing tools configured (e.g., via MCP):
-
-1. Navigate to the relevant page
-2. Verify the UI changes work as expected
-3. Take a screenshot if helpful for the progress log
-
-If no browser tools are available, note in your progress report that manual browser verification is needed.
-
-## Stop Condition
-
-After completing a user story, check if ALL stories have `passes: true`.
-
-If ALL stories are complete and passing, reply with:
-<promise>COMPLETE</promise>
-
-If there are still stories with `passes: false`, end your response normally (another iteration will pick up the next story).
-
-## Important
-
-- Work on ONE story per iteration
-- Commit frequently
-- Keep CI green
-- Read the Codebase Patterns section in progress.txt before starting

-# PRD: Adiuva — MVP Implementation
-
-> **Status:** APPROVED / READY FOR DEV
-> **Version:** 1.0 (MVP)
-> **Date:** 2026-02-19
-> **Stack:** Electron · React · TypeScript · shadcn/ui · Tailwind · Drizzle ORM · SQLite · LanceDB · GitHub Copilot SDK
-> **Figma:** [Full File](https://www.figma.com/design/FxyJG9kpou4DfD7jM9WHKP/Desk)
-
----
-
-## Introduction
-
-Adiuva is a local-first desktop workspace acting as a "Digital Executive Secretary." It centralizes notes, tasks, and project context into a local SQLite database and exposes a multi-agent AI layer (via GitHub Copilot SDK) that proactively surfaces insights and drafts actions. Data never leaves the machine, making it safe for enterprise environments.
-
----
-
-## Goals
-
-- Ship a working Electron desktop app with five sections: Home, Timeline, Tasks, Projects, Notes.
-- All data persisted locally in SQLite (zero cloud dependency for data storage).
-- Hierarchical Client → Sub-Client → Project structure fully navigable from a sidebar tree.
-- "Fluid Curtain" pull-down gesture that transitions any view into a full-screen AI chat scoped to the current context.
-- Multi-agent AI system (@Orchestrator, @ProjectAgent, @EmailAgent, @KnowledgeAgent) integrated via GitHub Copilot SDK.
-- Milestone completion = every section functional at the level described in User Stories below.
-
----
-
-## UI Summary (from Figma)
-
-### Shared Shell
-- **Left sidebar:** 240px, `#fafafa` background, border-right `#e5e5e5`.
-  - Top: Adiuva logo/wordmark.
-  - Nav items: Home (house icon), Timeline (chart-gantt icon), Tasks (clipboard-check icon), Projects (folder-kanban icon). Active item gets `#f5f5f5` accent + no extra border.
-  - Bottom: Collapse button (panel-left icon).
-- **Right edge:** Vertical rotated label "keep scrolling for AI / next section" + chevron-down. This is the visual affordance for the Fluid Curtain pull-down gesture.
-- **Font:** Geist (Regular 400, Medium 500, Semibold 600). Sizes: sm=14px, base=16px.
-- **Colors:** bg=`#ffffff`, foreground=`#0a0a0a`, muted=`#737373`, border=`#e5e5e5`, sidebar=`#fafafa`, sidebar-accent=`#f5f5f5`, primary=`#171717`, primary-fg=`#fafafa`.
-
-### HOME
-- Top-right corner: stat chip showing "N Task due" count.
-- Main area (centered, max-w ~1088px): AI greeting `✦ Hello, {name}` (Heading 2, Geist Semibold 30px, -1px tracking).
-- Below: AI-generated daily brief paragraph with **bold** key phrases inline.
-- Chat input box: white, border `#d4d4d4`, shadow-lg, 109px tall, placeholder "Ask me anythings...", Send button (black, icon + label) bottom-right of the box.
-- Below chat: 4 suggestion chips (`Item` component) — icon badge + short prompt text — in a 4-column flex row.
-
-### TIMELINE
-- Main content area: placeholder background `#fef2f2` (the Gantt chart is not yet designed in Figma; implementation is free to choose a library).
-- Same sidebar + right-edge Fluid Curtain affordance.
-
-### TASKS
-- Header row: 4 stat cards — "Total task", "To Do", "In Progress", "Completed" — each with an icon and count.
-- Below: search bar (full-width, placeholder "Search tasks or projects...") + "Order by" dropdown (right) + status filter tabs (All | To Do | In Progress | Completed).
-- Task list rows (flat, full-width):
-  - Checkbox (left)
-  - Title (bold, 14px) + description subtitle (gray, 14px)
-  - Priority chip: `HIGH` (up-arrow, red-toned) | `MEDIUM` (right-arrow, gray) | `LOW` (down-arrow, green-toned)
-  - Due date chip (calendar icon + "Due Mon DD")
-  - Breadcrumb path (Client > Sub-Client > Project, chevron-separated)
-  - Assignee (person icon + name string)
-- Completed tasks show row with green-tinted background.
-
-### PROJECTS
-- **Left panel (tree):** "Projects" heading + `+` new button + search input. Hierarchical tree: Client (folder, bold) → Sub-Client (folder) → Project (circle/file). Expand/collapse chevrons. Active project highlighted.
-- **Right panel (project detail):**
-  - Breadcrumb (Client > Sub-Client) at top.
-  - Project name as H1.
-  - 3 stat cards: Notes count | Tasks Complete (x/y fraction) | Checkpoints (x/y fraction).
-  - AI Project Summary card (sparkle icon + generated paragraph).
-  - **Project Timeline:** inline Gantt — months across top (Feb 2026, Mar 2026 …), horizontal bar with dot markers for each checkpoint. Legend: To Do (dark) / Completed (green). "+ Add" button top-right.
-  - **Tasks (Kanban):** 3 columns — To Do / In progress / Completed. Task cards: title, description, priority chip, due date, assignee. "+ Add" per column header.
-  - **Notes list:** flat list of note entries + "+ Add" button.
-
-### NOTES
-- Milkdown editor (standalone route) for writing/editing a single note.
-- Markdown-native, full-screen editor style.

-## User Stories
-
-### PHASE 1 — Foundation
-
----
-
-#### US-001: Electron + React scaffold
-**Description:** As a developer, I need a working Electron app with React+TypeScript and a shared main/renderer process setup so that all other features have a platform to run on.
-
-**Acceptance Criteria:**
-- [ ] `electron-builder` or `electron-vite` scaffold with hot-reload in dev.
-- [ ] Main process can open a `BrowserWindow` serving the React app.
-- [ ] TypeScript strict mode enabled, `tsconfig.json` configured.
-- [ ] `package.json` scripts: `dev`, `build`, `preview`.
-- [ ] App opens without errors on Linux, macOS, Windows.
-
----
-
-#### US-002: SQLite database + Drizzle ORM setup
-**Description:** As a developer, I need the SQLite database initialized with Drizzle ORM so that all CRUD operations use a typed, schema-driven interface.
-
-**Acceptance Criteria:**
-- [ ] `better-sqlite3` (or `@electric-sql/pglite` alternative) installed in main process.
-- [ ] Drizzle schema file defines all 5 tables (clients, projects, tasks, checkpoints, notes).
-- [ ] Migration runs on app start; DB file created at `~/.adiuva/data.db` (or `app.getPath('userData')`).
-- [ ] Drizzle Studio accessible in dev mode (`drizzle-kit studio`).
-- [ ] TypeScript types inferred from schema (no manual type duplication).
-
----
-
-#### US-003: App shell — sidebar navigation
-**Description:** As a user, I want a persistent left sidebar so that I can navigate between all sections of the app.
-
-**Acceptance Criteria:**
-- [ ] Sidebar renders at 240px with `#fafafa` background and right border.
-- [ ] Nav items: Home (house), Timeline (chart-gantt), Tasks (clipboard-check), Projects (folder-kanban). Each uses Lucide icon + label.
-- [ ] Active route highlights item with `#f5f5f5` accent background.
-- [ ] Collapse button at bottom toggles sidebar to icon-only mode (64px).
-- [ ] Router renders correct view for each nav item (React Router or TanStack Router).
-- [ ] Verify in browser using dev-browser skill.
-
----
-
-#### US-004: Client CRUD (hierarchical)
-**Description:** As a user, I want to create, rename, and delete Clients and Sub-Clients so that I can mirror real-world corporate structures.
-
-**Acceptance Criteria:**
-- [ ] "New Client" action creates a top-level client (parentId = null).
-- [ ] "New Sub-Client" action (available on a selected client) creates a child (parentId = selected client's id).
-- [ ] Client and Sub-Client names are editable via inline rename or modal.
-- [ ] Deleting a client warns if it has child clients or projects; cascade delete is opt-in.
-- [ ] Changes are immediately persisted to SQLite.
-- [ ] TypeScript types pass; no `any`.
-
----
-
-#### US-005: Project CRUD
-**Description:** As a user, I want to create projects attached to a client/sub-client or as standalone orphans so that I can track both client and internal work.
-
-**Acceptance Criteria:**
-- [ ] "New Project" dialog asks for name and optionally a client (dropdown, searchable).
-- [ ] Projects with no client appear under an "Internal / No Client" group in the tree.
-- [ ] Project can be re-parented (moved to a different client) via edit dialog.
-- [ ] Project status toggled between `active` and `archived`.
-- [ ] Archived projects hidden by default; toggle to show.
-- [ ] Persisted to SQLite immediately.
-
----
-
-#### US-006: Projects sidebar tree view
-**Description:** As a user, I want to see all clients, sub-clients, and projects in a collapsible tree in the Projects section so that I can navigate the hierarchy at a glance.
-
-**Acceptance Criteria:**
-- [ ] Tree renders: Client (folder icon) → Sub-Client (folder icon) → Project (circle icon).
-- [ ] Clients and sub-clients expand/collapse independently.
-- [ ] Search input filters tree in real-time (client name, sub-client name, project name).
-- [ ] Clicking a project loads the Project Detail panel on the right.
-- [ ] Active project is highlighted in the tree.
-- [ ] Verify in browser using dev-browser skill.
-
----
-
-#### US-007: Task CRUD (global Tasks view)
-**Description:** As a user, I want a global task list where I can create, filter, search, and update tasks so that I can manage all work across projects in one place.
-
-**Acceptance Criteria:**
-- [ ] 4 stat cards at top: Total, To Do, In Progress, Completed — update reactively.
-- [ ] Search filters tasks by title or description, case-insensitive.
-- [ ] Status filter tabs (All | To Do | In Progress | Completed) filter list.
-- [ ] "Order by" dropdown supports: Due Date, Priority, Created Date.
-- [ ] Task rows show: checkbox, title, description, priority chip (HIGH/MEDIUM/LOW with color), due date chip, breadcrumb (Client > Sub-Client > Project), assignee.
-- [ ] Clicking checkbox toggles status: todo → done (skip in_progress for quick-complete).
-- [ ] Inline "New Task" button opens a creation modal with fields: title, description, priority, due date, project (optional), assignee (optional).
-- [ ] All changes persisted to SQLite.
-- [ ] Verify in browser using dev-browser skill.

-#### US-008: Manual Timeline (global & per-project)
-**Description:** As a user, I want to view and manually create timeline checkpoints on a Gantt-style view so that I have full control over milestone dates.
-
-**Acceptance Criteria:**
-- [ ] Timeline view renders a horizontal time axis (months) with dot markers for each checkpoint.
-- [ ] Global Timeline shows checkpoints from all projects (color-coded by project or status).
-- [ ] Per-project timeline (in Project Detail) scoped to that project's checkpoints only.
-- [ ] "+ Add" button opens a dialog: title, date picker, project (in global view).
-- [ ] Checkpoint dots distinguish status: To Do (dark/filled) vs Completed (green).
-- [ ] "Today" marker line displayed on the timeline.
-- [ ] Clicking a checkpoint dot shows a popover with title, date, and delete action.
-- [ ] Persisted to SQLite.
-- [ ] Verify in browser using dev-browser skill.
-
----
-
-#### US-009: Project Detail view
-**Description:** As a user, I want a rich project detail panel that shows notes count, tasks summary, AI summary, timeline, Kanban, and notes list in one scrollable view.
-
-**Acceptance Criteria:**
-- [ ] Breadcrumb (Client > Sub-Client) rendered at top.
-- [ ] Stat cards: Notes count | Tasks Complete (x/y) | Checkpoints (x/y).
-- [ ] AI Project Summary card shows sparkle icon + placeholder text ("AI summary will appear here") until agent generates it.
-- [ ] Inline Project Timeline (same Gantt component as US-008, scoped).
-- [ ] Kanban board: To Do / In Progress / Completed columns. Task cards show title, description, priority, due date, assignee. Drag between columns updates `status`.
-- [ ] Notes list: title + creation date for each note. Click opens Milkdown editor. "+ Add" creates new note.
-- [ ] Verify in browser using dev-browser skill.
-
----
-
-#### US-010: Notes editor (Milkdown)
-**Description:** As a user, I want a full-screen Markdown editor for each note so that I can write rich content without leaving the app.
-
-**Acceptance Criteria:**
-- [ ] Milkdown editor renders in a dedicated route (`/notes/:noteId`).
-- [ ] Supports: headings, bold, italic, code blocks, bullet lists, ordered lists, blockquotes.
-- [ ] Auto-saves content to SQLite on change (debounced, 500ms).
-- [ ] Back navigation returns to the project detail view (or previous location).
-- [ ] Note title editable at the top (separate from Milkdown content).
-- [ ] Verify in browser using dev-browser skill.
-
----
-
-### PHASE 2 — The Fluid Curtain & Agents
-
----
-
-#### US-011: Fluid Curtain — pull-down gesture + animation
-**Description:** As a user, I want to pull down from the top of any view to slide the app off-screen and reveal the AI chat layer beneath.
-
-**Acceptance Criteria:**
-- [ ] Scrolling up past the top of content (overscroll) OR pressing a keyboard shortcut (e.g., `Cmd/Ctrl+K` or `⌥↓`) triggers the curtain.
-- [ ] App panel slides down using Framer Motion spring animation, exiting the bottom of the viewport.
-- [ ] AI Chat view is fully revealed below (full-screen, no sidebar obstruction).
-- [ ] Pulling the app back up (swipe/scroll from bottom or shortcut) re-covers the chat.
-- [ ] Animation is smooth (no jank). Spring config: stiffness 300, damping 30.
-- [ ] Right-edge "keep scrolling for AI" label and chevron are visible in every section as the affordance.
-- [ ] Verify in browser using dev-browser skill.
-
----
-
-#### US-012: Context-scoped AI chat
-**Description:** As a user, I want the AI chat (revealed by the curtain) to know the context I was in so that answers are scoped to the right project or global scope.
-
-**Acceptance Criteria:**
-- [ ] When curtain is pulled from a Project Detail view, a context header displays "Chatting about: [Project Name]".
-- [ ] When pulled from Home, context is global (all data).
-- [ ] Context is passed as a system message to the GitHub Copilot SDK call (project notes, tasks, checkpoints as structured JSON).
-- [ ] Agent responses reference only documents within the scoped project.
-- [ ] Chat history is session-only (not persisted in MVP).
-
----
-
-#### US-013: GitHub Copilot SDK integration + @Orchestrator
-**Description:** As a developer, I need the GitHub Copilot SDK wired up with an Orchestrator agent that routes user messages to the correct specialist agent.
-
-**Acceptance Criteria:**
-- [ ] SDK initialized in main process with enterprise credentials (from env/config).
-- [ ] `@Orchestrator` reads user intent and calls `route_to_project`, `route_to_general`, or `route_to_email` tool.
-- [ ] Routing result invokes the correct specialist agent and returns its response.
-- [ ] Streaming responses supported (tokens shown incrementally in chat UI).
-- [ ] Errors handled gracefully (SDK timeout, auth failure) with user-facing message.
-
----
-
-#### US-014: @ProjectAgent with project tools
-**Description:** As a user, I want the AI to answer project-specific questions and take actions (add task, suggest checkpoints) within the scoped project.
-
-**Acceptance Criteria:**
-- [ ] `read_project_notes` tool fetches all notes for the project from SQLite.
-- [ ] `add_task` tool creates a task in the project (writes to SQLite) and confirms in chat.
-- [ ] `suggest_checkpoints` tool returns a list of proposed checkpoints (title + date) as interactive cards in chat (Approve / Reject each).
-- [ ] Approved checkpoints are inserted into `checkpoints` table with `is_ai_suggested=1, is_approved=1`.
-- [ ] `get_summary` tool generates a 2-3 sentence project summary and updates `projects.ai_summary` in SQLite.
-
----
-
-### PHASE 3 — Intelligence & RAG
-
----
-
-#### US-015: LanceDB vector store setup + note embedding
-**Description:** As a developer, I need notes and project content embedded into LanceDB so that semantic search is possible across all projects.
-
-**Acceptance Criteria:**
-- [ ] LanceDB initialized in main process, storing vectors at `~/.adiuva/vectors/`.
-- [ ] On note save (create or update), content is embedded via GitHub Copilot SDK embeddings endpoint and stored in LanceDB with `{noteId, projectId, content}` metadata.
-- [ ] Existing notes are indexed on first startup (migration script).
-- [ ] Embedding errors logged but do not block the save operation.
-
----
-
-#### US-016: @KnowledgeAgent — semantic search across all projects
-**Description:** As a user, I want to ask "what did we decide about X?" and get answers pulled from across all past project notes, not just the current one.
-
-**Acceptance Criteria:**
-- [ ] `vector_search_all` tool accepts a query string, returns top-5 semantically similar note chunks from LanceDB.
-- [ ] Results include source note title and project name for attribution.
-- [ ] @Orchestrator routes knowledge queries to @KnowledgeAgent.
-- [ ] Response in chat includes inline citations ("From: Project A — Meeting Notes, Feb 12").
-
----
-
-#### US-017: AI checkpoint suggestions from notes
-**Description:** As a user, I want the AI to proactively analyze my meeting notes and suggest timeline checkpoints I may have missed.
-
-**Acceptance Criteria:**
-- [ ] Triggered manually ("Suggest checkpoints" button in Project Detail timeline header) or by @ProjectAgent tool call.
-- [ ] @ProjectAgent reads all notes for the project, extracts date-anchored commitments, returns as suggested checkpoints.
-- [ ] Suggestions appear as dismissible cards in the Timeline UI with `isAiSuggested=1, isApproved=0`.
-- [ ] Approve → `isApproved` set to 1, checkpoint appears on timeline.
-- [ ] Reject → checkpoint deleted.
-- [ ] Verify in browser using dev-browser skill.
-
----
-
-#### US-018: Home dashboard — AI daily brief
-**Description:** As a user, I want the Home screen to greet me with an AI-generated daily brief summarizing my tasks and suggesting actions.
-
-**Acceptance Criteria:**
-- [ ] On app open, @Orchestrator queries tasks due today/this week and recent project activity.
-- [ ] AI generates a personalized paragraph with key highlights (tasks due, suggested calls/emails).
-- [ ] Brief is displayed below the greeting with **bold** key phrases inline (as in Figma).
-- [ ] 4 suggestion chips below the chat box are pre-populated with context-relevant queries.
-- [ ] Chat box on Home is scoped globally (no project context).
-- [ ] Verify in browser using dev-browser skill.
-
----
-
-## Functional Requirements
-
-- **FR-01:** All data stored locally in SQLite at `app.getPath('userData')/adiuva.db`.
-- **FR-02:** App functions fully offline; AI features degrade gracefully when network is unavailable.
-- **FR-03:** Client tree supports unlimited nesting depth but UI only needs to display 3 levels (Client → Sub-Client → Project).
-- **FR-04:** Tasks table has a nullable `projectId`; global Tasks view shows all tasks regardless.
-- **FR-05:** The "Fluid Curtain" animation must not lose the underlying view state (app slides but remains mounted).
-- **FR-06:** GitHub Copilot SDK credentials are stored in OS keychain (not plaintext config).
-- **FR-07:** Milkdown auto-save uses a 500ms debounce; unsaved indicator shown if pending.
-- **FR-08:** All IDs are UUIDs (use `crypto.randomUUID()`).
-- **FR-09:** Drizzle migrations run automatically on startup; never destructive.
-- **FR-10:** Kanban drag-and-drop updates `tasks.status` and `tasks.updatedAt` immediately in SQLite.
-
----
-
-## Non-Goals (Out of Scope for MVP)
-
-- Email client / inbox integration (EmailAgent tools are stubs only).
-- Cloud sync or multi-device support.
-- Real assignee accounts (assignee is a plain name string, not a user entity).
-- Notifications or system tray alerts.
-- Dark mode.
-- Mobile or web version.
-- Export to PDF/CSV.
-- Notes version history.
-
----
-
-## Design Considerations
-
-- **Font:** Geist via `@fontsource/geist` or CDN. Apply globally via CSS variable.
-- **Icons:** Lucide React (house, chart-gantt, clipboard-check, folder-kanban, panel-left, send, sparkles, chevron-down).
-- **Gantt:** ✅ Custom SVG component. Month labels on X axis, `<circle>` dots for checkpoints, `<line>` baseline, `<TodayMarker>`. Use `ResizeObserver` for responsive width.
-- **Kanban:** ✅ `@hello-pangea/dnd` — `<DragDropContext>` wrapping 3 `<Droppable>` columns, each task a `<Draggable>`.
-- **Fluid Curtain:** ✅ `framer-motion` `useMotionValue` + `useSpring`. Trigger: `wheel` event at `scrollTop === 0 && deltaY < 0` OR `Cmd/Ctrl+K`. Right-edge "keep scrolling for AI" label is a **visual hint only** (not interactive).
-- **shadcn/ui components to reuse:** Button, Input, Badge, Card, Dialog, Separator, Tabs, Tooltip, DropdownMenu, Popover.
-
----
-
-## Technical Considerations
-
-- **IPC:** ✅ `electron-trpc`. Define a single `appRouter` in main process exposing all domains (`tasks`, `projects`, `clients`, `checkpoints`, `notes`, `ai`). Renderer uses `trpc.[domain].[procedure].useQuery/useMutation()`. Zod validates all inputs at the boundary.
-- GitHub Copilot SDK may require enterprise SSO token; provide a settings screen for token input (US not in MVP scope, but infrastructure must exist).
-- LanceDB Node.js binding (`vectordb` package) runs in main process only.
-- Milkdown v7+ with React adapter. Plugin list: `commonmark`, `history`, `clipboard`, `math` (optional).
-- Use `electron-store` or `conf` for lightweight app settings (user name for greeting, sidebar collapsed state, etc.).
-
----
-
-## Success Metrics
-
-- All 5 sections navigable and functional with real SQLite-persisted data.
-- Fluid Curtain animation runs at 60fps with no layout shift on return.
-- @ProjectAgent correctly scopes a context query (zero responses sourcing from another project).
-- Note embedding + LanceDB retrieval returns relevant results for a simple semantic query.
-- App cold-start < 3 seconds on a modern machine.
-

-
-## Open Questions
-
-1. ~~**Gantt library vs. custom SVG?**~~ ✅ Resolved: custom SVG component.
-2. ~~**GitHub Copilot SDK auth flow:**~~ ✅ Resolved: `keytar` (OS keychain). A minimal "Settings" screen for token input writes to keychain on save.
-3. ~~**IPC architecture:**~~ ✅ Resolved: `electron-trpc` with Zod validation. All DB/AI operations exposed as tRPC procedures in main process; renderer uses typed React Query hooks.
-4. **Milkdown vs. simpler editor:** Milkdown is powerful but has a learning curve. Is a simpler `CodeMirror`-based Markdown editor acceptable for MVP?
-5. **"Fluid Curtain" on Linux:** Overscroll behavior differs across OS/window managers. What's the fallback trigger (keyboard shortcut only)?

-## Codebase Patterns
-- `alias(table, 'alias_name')` from `drizzle-orm/sqlite-core` enables self-joins (e.g., clients → parentClients for hierarchy)
-- `sql<T>\`CASE WHEN ... THEN ... ELSE ... END\`` for conditional SELECT fields (e.g., clientName vs subClientName based on parentId)
-- `or(like(col1, pattern), like(col2, pattern))` for multi-column search; SQLite LIKE on NULL columns safely returns NULL (falsy) so OR is safe
-- Vite configs use `.mts` extension (not `.ts`) to avoid ESM/CJS conflict with electron-forge's externalize-deps plugin
-- electron-trpc uses `exposeElectronTRPC()` in preload and `createIPCHandler({ router, windows })` in main; renderer uses `ipcLink()` from `electron-trpc/renderer`
-- appRouter lives at `src/main/router/index.ts`; renderer client at `src/renderer/lib/trpc.ts`
-- `@/*` path alias maps to `src/renderer/*` (configured in tsconfig.json paths)
-- Drizzle ORM with better-sqlite3 (sync driver): SELECT queries MUST end with `.all()` to execute; INSERT/UPDATE/DELETE MUST end with `.run()`
-- `inArray(column, values)` works with nullable columns when values is `string[]` (TypeScript covariance allows string[] → (string | null)[])
-- All DB tables use `CREATE TABLE IF NOT EXISTS` for non-destructive migrations
-- All IDs are UUIDs generated via `crypto.randomUUID()`
-- TypeScript strict mode + noUncheckedIndexedAccess enabled; always account for possible undefined on array access
-- electron-store@8 (CJS) used for app settings; use lazy init pattern `getStore()` like `getDb()` to avoid calling before app ready
-- ESLint uses `eslint-import-resolver-typescript` to resolve `@/*` aliases; configured in `.eslintrc.json` under `settings.import/resolver`
-- App settings (sidebar state, etc.) exposed via `settings` tRPC sub-router for type-safe renderer access
-- `z.string().nullable().optional()` in tRPC inputs enables three-state semantics: undefined = don't change, null = clear, string = set value
-- NewTaskDialog component at `src/renderer/components/tasks/NewTaskDialog.tsx` accepts `defaultProjectId` and `defaultStatus` props for reuse in Kanban column "+ Add" buttons
-- `date-fns` is available as a transitive dependency of `react-day-picker` (shadcn/ui calendar)
-- GanttChart component at `src/renderer/components/timeline/GanttChart.tsx` is reusable: accepts `defaultProjectId` to scope to a project (for US-015 inline timeline)
-- AddCheckpointDialog at `src/renderer/components/timeline/AddCheckpointDialog.tsx` accepts `defaultProjectId` — hides project select when provided
-- TanStack Router `validateSearch` with Zod schema for passing selected-item IDs via URL search params (e.g., `?projectId=...`)

-## 2026-02-19 - US-002
-- Installed `better-sqlite3`, `drizzle-orm` (runtime) and `@types/better-sqlite3`, `drizzle-kit` (dev)
-- Created `src/main/db/schema.ts`: 5 tables (clients, projects, tasks, checkpoints, notes) with exported InferSelectModel/InferInsertModel types
-- Created `src/main/db/index.ts`: `initDb()` opens/creates `adiuva.db` at `app.getPath('userData')`, runs CREATE TABLE IF NOT EXISTS (non-destructive), enables WAL mode; `getDb()` singleton accessor
-- Updated `src/main/index.ts`: call `initDb()` in `app.on('ready')`
-- Updated `vite.main.config.mts`: externalized `better-sqlite3`
-- Updated `forge.config.ts`: added `AutoUnpackNativesPlugin`
-- Added `drizzle.config.ts` for drizzle-kit CLI
-- Typecheck: passes with zero errors
-- **Learnings for future iterations:**
-  - better-sqlite3 is CommonJS with native addon; Vite must NOT bundle it — always add to rollupOptions.external
-  - The CREATE TABLE IF NOT EXISTS approach satisfies "never destructive" and works perfectly in electron without needing migration file resolution
-  - electron-forge rebuilds native modules automatically on `electron-forge start`; no manual rebuild step needed
-  - `app.getPath('userData')` is only available after `app.on('ready')` fires — do not call earlier

-## 2026-02-19 - US-008
-- What was implemented:
-  - Full `checkpointsRouter` replacing stubs in `src/main/router/index.ts`
-  - Full `notesRouter` replacing stubs in `src/main/router/index.ts`
-  - Added `checkpoints` and `notes` to the schema import
-  - `checkpoints.list`: optional `projectId` filter, ordered by `asc(checkpoints.date)`
-  - `checkpoints.create`: inserts with UUID, createdAt=Date.now(), defaults isAiSuggested/isApproved to 0
-  - `checkpoints.update`: partial set for title/date/isApproved
-  - `checkpoints.delete`: deletes by id, returns `{ success: true }`
-  - `notes.list`: returns `{ id, projectId, title, createdAt, updatedAt }` only — no content (performance)
-  - `notes.get`: returns full record or null via `.all()[0] ?? null` pattern
-  - `notes.create`: inserts with UUID, createdAt=updatedAt=Date.now()
-  - `notes.update`: partial set, always sets updatedAt=Date.now() regardless of which fields changed
-  - `notes.delete`: deletes by id, returns `{ success: true }`
-- Files changed: `src/main/router/index.ts`, `prd.json`, `progress.txt`
-- **Learnings for future iterations:**
-  - `notes.update` must always set `updatedAt` — build the set object with updatedAt outside the conditional block
-  - `notes.list` intentionally excludes `content` column for performance; use `notes.get` for full record
-  - `checkpoints.projectId` is `.notNull()` in schema (unlike tasks.projectId which is nullable) — no null coalescing needed

-## 2026-02-19 - US-003
-- What was implemented:
-  - Installed: electron-trpc, @trpc/server, @trpc/client, @trpc/react-query, @tanstack/react-query, zod
-  - Created `src/main/router/index.ts` with full appRouter: stub routers for health, clients, projects, tasks, checkpoints, notes, ai
-  - Updated `src/preload/index.ts` to call `exposeElectronTRPC()`
-  - Updated `src/main/index.ts` to call `createIPCHandler({ router: appRouter, windows: [win] })`; `createWindow()` now returns `BrowserWindow`
-  - Created `src/renderer/lib/trpc.ts` with `createTRPCReact<AppRouter>()`
-  - Updated `src/renderer/index.tsx` to wrap app in `TRPCProvider` + `QueryClientProvider`
-  - Updated `src/renderer/routes/index.tsx` to call `trpc.health.ping.useQuery()` and display 'tRPC IPC bridge: pong'
-- Files changed: package.json, package-lock.json, prd.json, src/main/index.ts, src/main/router/index.ts (new), src/preload/index.ts, src/renderer/index.tsx, src/renderer/lib/trpc.ts (new), src/renderer/routes/index.tsx
-- **Learnings for future iterations:**
-  - electron-trpc `exposeElectronTRPC` is imported from `electron-trpc/main` (not a separate package)
-  - `ipcLink` is imported from `electron-trpc/renderer` in the renderer process
-  - `createTRPCReact<AppRouter>()` requires importing the AppRouter type from the main process router — this is a type-only import so it doesn't bundle main process code into renderer
-  - The TRPCProvider must wrap QueryClientProvider (or be a sibling); both need the same queryClient instance
-  - Stub routers return empty arrays or null — they will be replaced in US-005 through US-008
----
-
-## 2026-02-19 - US-004
-- What was implemented:
-  - Installed: electron-store@8 (CJS-compatible, for persistent app settings), @fontsource/geist (self-hosted Geist font), eslint-import-resolver-typescript (ESLint path alias fix)
-  - Created `src/main/store.ts` with lazy `getStore()` pattern using electron-store
-  - Added `settings` tRPC sub-router with `getSidebarCollapsed` query and `setSidebarCollapsed` mutation
-  - Updated `src/renderer/components/layout/AppShell.tsx` to: persist sidebar collapse via tRPC, add right-edge 'keep scrolling for AI' vertical label with ChevronDown icon
-  - Updated `src/renderer/globals.css`: replaced Google Fonts CDN with @fontsource/geist imports (weights 400/500/600)
-  - Updated `index.html`: removed Google Fonts CDN links
-  - Updated `.eslintrc.json`: added eslint-import-resolver-typescript to fix @/* alias resolution (fixed all 7 pre-existing lint errors)
-- Files changed: .eslintrc.json, index.html, package.json, package-lock.json, src/main/router/index.ts, src/main/store.ts (new), src/renderer/components/layout/AppShell.tsx, src/renderer/globals.css
-- **Learnings for future iterations:**
-  - Use electron-store@8 (not v9+) — v9+ is ESM-only and breaks with CommonJS main process
-  - electron-store must NOT be initialized at module import time (before app.ready); use lazy `getStore()` like `getDb()` pattern
-  - For sidebar/UI state loaded from IPC: use `localState ?? queryData ?? default` pattern to avoid flash while query resolves
-  - @fontsource packages are the npm equivalent of Google Fonts — import weight-specific CSS files (e.g., `@fontsource/geist/400.css`)
-  - ESLint `import/no-unresolved` requires `eslint-import-resolver-typescript` with `alwaysTryTypes: true` to resolve TypeScript path aliases
-  - The `writingMode: 'vertical-rl'` + `transform: 'rotate(180deg)'` CSS pattern creates bottom-to-top text for vertical affordance labels
----
-
-## 2026-02-19 - US-006
-- What was implemented:
-  - Full `projectsRouter` replacing stubs in `src/main/router/index.ts`
-  - Added `and` to drizzle-orm imports
-  - `projects.list`: uses `and()` with optional conditions for `clientId` filter and archived filter (defaults to active only)
-  - `projects.listAll`: returns only `{ id, name }` columns for dropdown use
-  - `projects.get`: `.all()` then `result[0] ?? null` pattern for nullable single-record lookup
-  - `projects.create`: inserts with UUID, status='active', createdAt=Date.now()
-  - `projects.update`: partial set object — only sets defined fields
-  - `projects.delete`: nulls `tasks.projectId` for all tasks in the project, then deletes the project
-- Files changed: `src/main/router/index.ts`, `prd.json`, `progress.txt`
-- **Learnings for future iterations:**
-  - `and(...conditions)` from drizzle-orm accepts `(SQL | undefined)[]` — pass `undefined` for optional conditions and drizzle filters them out automatically
-  - For nullable single-record queries: use `.all()` and `result[0] ?? null` (strict mode forbids `.get()` direct null return without this pattern)
-  - `and()` returns `SQL<unknown> | undefined` which `.where()` accepts directly (no extra wrapping needed)
-
----
-
-## 2026-02-19 - US-005
-- What was implemented:
-  - Full clients tRPC router replacing stubs in `src/main/router/index.ts`
-  - Added imports: `eq`, `asc`, `inArray` from `drizzle-orm`; `getDb` from `../db`; `clients`, `projects`, `tasks` from `../db/schema`
-  - `clients.list`: `db.select().from(clients).orderBy(asc(clients.name)).all()`
-  - `clients.create`: inserts with `crypto.randomUUID()` + `Date.now()` via `.run()`
-  - `clients.update`: partial update — only sets fields that are defined in input, skips if no-op
-  - `clients.delete`: checks for child clients and child projects; returns `{ error: string }` payload if any exist; otherwise deletes and returns `{ success: true }`
-  - `clients.deleteWithCascade`: BFS loop collects all descendant client IDs, finds their projects, nulls `projectId` on orphaned tasks, deletes projects, then deletes all clients
-- Files changed: `src/main/router/index.ts`, `prd.json`, `progress.txt`
-- **Learnings for future iterations:**
-  - Drizzle ORM with better-sqlite3 sync driver: SELECT must call `.all()` to get an array; INSERT/UPDATE/DELETE must call `.run()` to execute — NOT calling these causes TypeScript errors (query builder ≠ result)
-  - `inArray(nullableColumn, string[])` is TypeScript-safe because `string[]` is assignable to `(string | null)[]` via covariance
-  - Guard against empty arrays before using `inArray` — while `allClientIds` is never empty (starts with input.id), `projectIds` could be empty; guarded with `if (projectIds.length > 0)` block
-  - `@typescript-eslint/no-non-null-assertion` is configured as a warning (not error) in this project — `queue.shift()!` is fine after a `length > 0` check
----
-
-## 2026-02-19 - US-007
-- What was implemented:
-  - Full `tasksRouter` replacing stubs in `src/main/router/index.ts`
-  - Added imports: `or`, `like`, `sql` from `drizzle-orm`; `alias` from `drizzle-orm/sqlite-core`
-  - `tasks.list`: LEFT JOINs projects → clients → parentClients (alias for self-join); CASE WHEN for clientName/subClientName breadcrumb fields; `and()` with optional conditions for projectId/status/search; `like()` OR search on title+description; CASE expression for priority ordering
-  - `tasks.create`: inserts with UUID, defaults (status='todo', priority='medium'), createdAt=Date.now()
-  - `tasks.update`: partial set object — only sets defined fields
-  - `tasks.delete`: deletes by id, returns `{ success: true }`
-- Files changed: `src/main/router/index.ts`, `prd.json`, `progress.txt`
-- **Learnings for future iterations:**
-  - `alias(table, 'alias_name')` is from `drizzle-orm/sqlite-core` (NOT `drizzle-orm`) for SQLite self-joins
-  - `sql<T>\`CASE WHEN ${col} IS NOT NULL THEN ${alias.col} ELSE ${col} END\`` for conditional field selection using drizzle template literals
-  - `or(like(col1, pattern), like(col2, pattern))` composes safely — null columns evaluate to NULL (falsy) in WHERE
-  - For priority ordering: `asc(sql\`CASE ${tasks.priority} WHEN 'high' THEN 1 WHEN 'medium' THEN 2 WHEN 'low' THEN 3 ELSE 4 END\`)` puts high priority first
----
-
-## 2026-02-19 - US-009
-- What was implemented:
-  - Verified existing `ProjectSidebar` component at `src/renderer/components/projects/ProjectSidebar.tsx` satisfies all US-009 acceptance criteria
-  - New Project button at top using shadcn/ui Button + `clients.create` mutation with auto-rename on success
-  - Kebab context menu (DropdownMenu) with Rename, New Sub-Project, Delete actions
-  - Inline rename: Input replaces label, Enter saves via `clients.update`, Escape cancels, blur saves
-  - Delete: AlertDialog with two stages — initial confirm, then cascade-warn if children exist (uses `clients.delete` first, falls back to `clients.deleteWithCascade`)
-  - Hierarchical tree via `buildTree()` function (parent-child via `clients.parentId`)
-  - Empty state with EmptyMedia + call-to-action button
-  - All mutations invalidate `clients.list` query for immediate tree refresh
-  - Typecheck passes (zero errors), lint passes (1 non-null assertion warning, guarded)
-- Files changed: `scripts/ralph/prd.json`, `scripts/ralph/progress.txt`
-- **Learnings for future iterations:**
-  - The ProjectSidebar was built as part of US-004 app shell work but the US-009 story wasn't marked as passing — always check existing code before implementing
-  - `useCallback` ref pattern (`ref={callbackRef}`) is used for auto-focus + select on mount without useEffect
-  - The two-stage delete flow (try simple delete first → if error, show cascade option) maps well to the backend's `clients.delete` (guards) + `clients.deleteWithCascade` (force) pattern
----
-
-## 2026-02-19 - US-010
-- What was implemented:
-  - Rewrote `ProjectSidebar` from a client-hierarchy tree to a project-centric sidebar grouped by client
-  - Projects grouped by `clientId` using Collapsible headers; projects without a client appear under "Internal / No Client"
-  - Search input filters projects by name in real-time (auto-expands all groups when searching)
-  - Show/hide archived projects via Switch toggle (queries `projects.list` with `includeArchived`)
-  - Context menu per project (DropdownMenu): Edit Client (Dialog + Select to assign/change/remove client), Archive/Unarchive, Delete (AlertDialog)
-  - Clicking a project sets `projectId` in search params → renders ProjectDetail placeholder in right pane
-  - Active project highlighted with `bg-sidebar-accent`
-  - Updated `projects.update` tRPC procedure to accept `clientId: z.string().nullable().optional()` (allows unlinking from client)
-  - Created placeholder `ProjectDetail` component (full implementation deferred to US-013)
-  - Installed shadcn/ui: dialog, select, switch
-- Files changed: `src/renderer/components/projects/ProjectSidebar.tsx`, `src/renderer/routes/projects.tsx`, `src/renderer/components/projects/ProjectDetail.tsx` (new), `src/main/router/index.ts`, `src/renderer/components/ui/dialog.tsx` (new), `src/renderer/components/ui/select.tsx` (new), `src/renderer/components/ui/switch.tsx` (new), `scripts/ralph/prd.json`, `scripts/ralph/progress.txt`
-- **Learnings for future iterations:**
-  - TanStack Router `validateSearch` with Zod schema is the cleanest way to pass selected-item IDs via URL search params without creating nested routes
-  - `Route.useNavigate()` returns a typed navigate fn; use `void navigate({ search: { ... } })` to avoid unhandled promise warnings
-  - For project grouping, query both `projects.list` and `clients.list` separately then join in-memory via a Map — avoids complex SQL joins for display-only data
-  - `projects.update` with `clientId: z.string().nullable().optional()` allows three states: undefined (don't change), null (unlink), string (assign)
-  - Auto-expanding all groups during search (`effectiveExpanded` computed from grouped keys) gives a better UX than forcing users to manually expand
----
-
-## 2026-02-20 - US-011
-- What was implemented:
-  - Full Global Tasks view UI at `/tasks` route
-  - 4 stat cards (Total Tasks, To Do, In Progress, Completed) using shadcn/ui Card components with Lucide icons, reactively updated from unfiltered `tasks.list` query
-  - Search bar with 300ms debounce using shadcn/ui Input + Search icon
-  - Status filter tabs using shadcn/ui Tabs (All | To Do | In Progress | Completed)
-  - "Order by" dropdown using shadcn/ui DropdownMenu (Due Date | Priority | Created Date)
-  - Task rows with: shadcn/ui Checkbox (toggles todo↔done), title (bold 14px), description (muted truncated), priority Badge (HIGH=destructive, MEDIUM=secondary, LOW=outline green), due date chip (calendar icon + formatted date), breadcrumb (Client > Sub-Client > Project with ChevronRight separators), assignee (User icon + name)
-  - Completed task rows have green-tinted background (`bg-green-50 border-green-200`)
-  - NewTaskDialog component with: Input for title (required), Textarea for description, Select for priority/status, Popover+Calendar for due date, Select for project (from `projects.listAll`), Input for assignee
-  - Installed shadcn/ui components: card, tabs, checkbox, badge, textarea, popover, calendar
-- Files changed: `src/renderer/routes/tasks.tsx`, `src/renderer/components/tasks/NewTaskDialog.tsx` (new), `src/renderer/components/ui/card.tsx` (new), `src/renderer/components/ui/tabs.tsx` (new), `src/renderer/components/ui/checkbox.tsx` (new), `src/renderer/components/ui/badge.tsx` (new), `src/renderer/components/ui/textarea.tsx` (new), `src/renderer/components/ui/popover.tsx` (new), `src/renderer/components/ui/calendar.tsx` (new), `scripts/ralph/prd.json`, `scripts/ralph/progress.txt`
-- **Learnings for future iterations:**
-  - Use two separate `tasks.list` queries: one unfiltered `{}` for stat card counts, one with filters for the displayed list — ensures stats always reflect total counts
-  - `date-fns` `format(date, 'PPP')` produces "February 20th, 2026" style dates — already installed as a dependency of react-day-picker (shadcn/ui calendar)
-  - shadcn/ui Select with an empty string value (`<SelectItem value="">No project</SelectItem>`) works as a "none" option for optional fields
-  - The Popover+Calendar date picker pattern is standard shadcn/ui: Popover wraps a Button trigger showing the formatted date, PopoverContent contains the Calendar
-  - Electron app runs at `http://localhost:5173` in dev mode but only within the Electron BrowserWindow — Playwright browser testing requires the Electron-specific test harness, not direct URL navigation
----
-
-## 2026-02-20 - US-012
-- What was implemented:
-  - Reusable `GanttChart` SVG component at `src/renderer/components/timeline/GanttChart.tsx`
-  - Accepts `{ checkpoints: GanttCheckpoint[], startDate: Date, endDate: Date, onDelete? }` props
-  - Custom SVG rendering: month labels on X axis, horizontal baseline `<line>`, `<circle>` dots for checkpoints positioned by date
-  - Dot fill logic: dark (#171717) for future approved checkpoints, green (#16a34a) for past approved, dashed outline (#737373) for pending AI suggestions (isApproved=0)
-  - Vertical red "Today" marker line at current date
-  - ResizeObserver for responsive SVG width
-  - foreignObject + shadcn/ui Popover on each dot click: shows title, formatted date, project name, and destructive Delete button
-  - `AddCheckpointDialog` component at `src/renderer/components/timeline/AddCheckpointDialog.tsx`: title Input (required), Popover+Calendar date (required), Select project dropdown (required in global view, hidden when `defaultProjectId` provided)
-  - Global Timeline route (`/timeline`) renders GanttChart with all checkpoints, project name lookup via Map from `projects.listAll`
-  - Legend showing dot types, empty state message when no checkpoints
-- Files changed: `src/renderer/components/timeline/GanttChart.tsx` (new), `src/renderer/components/timeline/AddCheckpointDialog.tsx` (new), `src/renderer/routes/timeline.tsx`
-- **Learnings for future iterations:**
-  - `foreignObject` inside SVG is the cleanest way to embed React components (like Popover) on SVG elements — set `overflow-visible` class to prevent clipping
-  - Checkpoints don't have a `status` field; use `isApproved=1` + `date < now` heuristic for "completed" vs "todo" dot color
-  - Date range for the Gantt is computed dynamically: 1 month before earliest date, 2 months after latest date — ensures comfortable visual padding
-  - GanttChart is designed for reuse: the `defaultProjectId` prop on AddCheckpointDialog pre-selects the project and hides the dropdown (for per-project timeline in US-015)
-  - `trpc.projects.listAll.useQuery(undefined, { enabled: showProjectSelect })` prevents unnecessary queries when project is already known
