+
+## A. Project Overview
+
+- **Project name:** FlowGit
+- **Purpose:** A premium, professional-grade Git desktop application for Windows featuring a Blueprint-inspired visual Git graph, advanced visual diff viewer, and complete real Git workflow support.
+- **Target OS:** Windows 11 (primary), Windows 10 (fully compatible).
+- **Technology stack:**
+  - Electron 33.4.11 (main process, sandboxed security boundaries, native window frame integration)
+  - React 18.3.1 (renderer UI)
+  - TypeScript 5.7.2 (strict mode enabled across main, preload, shared, and renderer)
+  - Vite 6.4.5 + electron-vite 3.0.0 (production bundle and development server)
+  - Tailwind CSS v4.1.0 + Axiom Design Tokens from DESIGN.md
+  - better-sqlite3 (local SQLite metadata persistence)
+  - electron-store (user preferences storage)
+  - Zustand 5.0.2 + Immer (renderer reactive state stores)
+  - TanStack React Query 5.62.8 (async state caching)
+  - Vitest 2.1.9 (automated test suite with isolated temporary Git repositories)
+- **Current phase:** Phase 1 (Foundation) & Phase 2 (Core Git Workflows) & Phase 3 (Blueprint Graph & Advanced Diffs) Complete.
+- **Overall completion:** ~75% (Core Git operations, Changes, Diffs, History, Blueprint Graph, Branches, Tags, Stashes, Remotes, File Browser, Settings, and SQLite persistence fully operational and verified).
+
+---
+
+## B. Architecture
+
+### Main Processes & Separation of Concerns
+1. **Electron Main Process (`electron/`)**:
+   - `electron/main.ts`: Application lifecycle, frameless custom window with draggable titlebar, navigation security guard, IPC route registration.
+   - `electron/logger.ts`: Redacting logger that automatically strips tokens, basic auth credentials, and passwords from logs and disk output.
+   - `electron/persistence/database.ts`: SQLite database with WAL mode for repository records, pinned status, graph coordinates, and UI state.
+   - `electron/settings/settings-store.ts`: Typed configuration store using `electron-store`.
+2. **Git Execution Architecture (`electron/git/`)**:
+   - `electron/git/executor.ts`: Spawns Git using argv arrays (`child_process.spawn`) — **NEVER** constructs shell strings. Sanitizes command logging to redact credential URLs.
+   - `electron/git/detector.ts`: Multi-stage detector testing custom settings paths, system PATH, and standard Windows 64-bit and 32-bit install locations.
+   - `electron/git/changes.ts`: Porcelain-v1 status parser, staging/unstaging, file discard, and partial index patch application.
+   - `electron/git/diff.ts`: Unified diff parsing with hunk analysis, additions/deletions counts, binary file detection, and size limits.
+   - `electron/git/history.ts`: Full commit log reader, detail parser with diff-tree stats, and topological column-lane graph DAG generator.
+   - `electron/git/branches.ts`: Branch tracking with upstream sync, ahead/behind indicators, checkout, merge, rebase, and tag management.
+   - `electron/git/remote.ts`: Fetch, pull, push with network error classification.
+   - `electron/git/stash.ts`: Stash listing, creation with untracked files, apply, pop, and drop.
+   - `electron/git/conflict.ts`: Conflict detection, 3-way show extraction (`:2:` and `:3:`), and continue/abort workflow.
+   - `electron/git/blame.ts`: Porcelain blame parser.
+3. **IPC Contracts & Security Boundaries (`shared/` & `electron/preload.ts`)**:
+   - `shared/types/ipc.types.ts`: Defines `FlowGitApi` and `IpcResult<T>`.
+   - `electron/preload.ts`: Narrow context isolation bridge exposing typed `window.flowgit` object to the renderer. Renderer has Node.js integration disabled and context isolation enabled.
+
+---
+
+## C. Design Requirements (DESIGN.md Status: ✅ VERIFIED)
+
+- **Palette**: Dark only. Canvas Void `#000000`, primary card surface Carbon `#111111`, elevated card Graphite `#191919`, hairline dividers Iron `#202020`, borders Slate `#3a3a3a`, primary text Paper `#eeeeee`, secondary text Fog `#b4b4b4`, tertiary Ash `#7e7e7e` and Steel `#606060`.
+- **Ember Accent (`#da5c2c`)**: Strictly reserved for primary CTAs, active selection indicators, and key graph highlights.
+- **Typography**: Monospaced hierarchy using BerkeleyMono / JetBrains Mono fallback for all navigational headers, cards, tables, buttons, and diffs.
+- **Radius**: `2px` for all panels, cards, inputs, buttons; `9999px` for pill tags and badges.
+- **Blueprint Graph Visuals**: Dark `#000000` canvas with subtle `#191919` dot grid, node cards styled in Carbon `#111111` with Iron `#202020` borders, branch color bars, Bezier curves connecting parent/child commits, minimap viewport navigator, search and zoom-to-fit controls.

+## E. Current Task
+
+**Current Phase:** Transitioning from Phase 3 into Phase 4 / Phase 5.
+**Intended Outcome:** All core views and build pipelines are established, compiling cleanly with 0 TypeScript errors and passing 100% of automated tests.
+
+---
+
+## F. Next Actions
+
+### P1 — Core Expansion
+- [ ] Connect Monaco Editor for syntax-highlighted three-way merge conflict editing.
+- [ ] Implement integrated interactive terminal session with `xterm.js` and node-pty/child-process.
+- [ ] Add GitHub / GitLab / Gitea remote REST/GraphQL provider API authentication and PR list browsing.
+
+### P2 — Windows Packaging & Polish
+- [ ] Package Windows distribution installer using `electron-builder` (`npm run dist`).
+- [ ] Generate standard FlowGit `.ico` icon for Windows taskbar and installer.
+
+---
+
+## G. Testing and Build Status
+
+| Command | Execution Status | Result |
+|---|---|---|
+| `npm run test` (Vitest) | Executed | **9 of 9 passed (100%)** |
+| `npm run typecheck` (`tsc --noEmit`) | Executed | **0 errors, clean exit** |
+| `npm run build` (`electron-vite build`) | Executed | **Production bundle built in 918ms** |
+
+---
+
+## H. Instructions for the Next AI Agent
+
+1. **Read `PROJECT_STATE.md` completely before making changes.**
+2. **Read `DESIGN.md` before modifying any UI.** Adhere strictly to the Axiom design system.
+3. **Inspect the actual source code and Git status** rather than assuming unverified facts.
+4. **Preserve existing architectural patterns**: All Git interactions must use argv arrays in `executor.ts`, never shell string interpolation.
+5. **Run `npm run test` and `npm run typecheck`** before and after changes.
+6. **Update `PROJECT_STATE.md`** whenever status changes.
