+
+## Project Overview
+
+Mission Control (MC) is an ADHD-centric personal productivity hub built with Tauri + React. It unifies GitLab activity (via gitlore) and beads task tracking into a single native interface.
+
+**Core principle:** Surface THE ONE THING you should be doing right now.
+
+## Key Documents
+
+- `PLAN.md` — Complete implementation plan with architecture, ACs, and reasoning
+
+## Tech Stack
+
+- **Shell:** Tauri 2.0 (Rust backend)
+- **Frontend:** React 19 + Vite + Tailwind + shadcn/ui
+- **State:** Zustand + TanStack Query
+- **Animations:** Framer Motion
+
+## External Dependencies
+
+MC shells out to these CLIs (does NOT import them as libraries):
+
+- `lore --robot` — GitLab data (issues, MRs, activity)
+- `br` — Beads task management (create, close, list)
+- `bv --robot-*` — Beads triage recommendations
+
+## Local State
+
+All MC-specific state lives in `~/.local/share/mc/`:
+
+| File | Purpose |
+|------|---------|
+| `gitlab_bead_map.json` | Maps GitLab events to bead IDs (deduplication) |
+| `decision_log.jsonl` | Append-only log of all user decisions with context |
+| `state.json` | Current focus, queue order, UI state |
+| `settings.json` | User preferences |
+
+## Key Architectural Decisions
+
+1. **Beads are the universal task graph** — GitLab items auto-create beads via MC's bridge
+2. **Manual priority first** — User sets THE ONE THING, MC logs decisions to learn patterns
+3. **CLI integration over library imports** — Clean boundaries, no schema coupling
+4. **Rich decision logging** — Every action logged with context and optional reasoning
+
+## Development Commands
+
+```bash
+# Frontend dev
+npm run dev
+
+# Tauri dev (frontend + backend)
+npm run tauri dev
+
+# Build
+npm run tauri build
+```
+
+## Code Quality
+
+- Run `cargo clippy -- -D warnings` before committing Rust changes
+- Run `npm run lint` before committing frontend changes
+- Follow existing patterns in the codebase
