## [1.0.0] — 2026-03-09

### 🎉 First Stable Release

Graph Notes reaches 1.0 — a local-first, graph-based note-taking app built with Tauri, React, and Rust.

### Hardened
- **Atomic writes** — all file saves use write→fsync→rename→fsync-parent to prevent corruption on crash/power loss
- **Path validation** — `safe_vault_path()` applied to all 20 file-access commands, preventing directory traversal
- **Filename sanitization** — `safe_name()` rejects path separators in workspace, canvas, and attachment names
- **Note-switch save race** — debounced save now captures note path at call time, preventing old content from being written to wrong note
- **Save pipeline consistency** — slash command insert and image paste now route through the standard debounced save with `domToMarkdown()`
- **Git error handling** — `git_status`, `git_commit`, `git_init` now check exit codes and surface stderr on failure
- **Silent error swallowing** — fixed 2 `let _ = fs::write()` sites to propagate errors
- **Panic prevention** — replaced `unwrap()` with `unwrap_or_default()` on fallible `file_name()` calls
- **Export safety** — `export_vault_zip` skips in-progress `~tmp` atomic write files
- **Regex performance** — all 10 per-call `Regex::new()` migrated to `LazyLock` statics

### Fixed
- **Rust compilation** — resolved duplicate `dirs_config_path()` definition and removed reference to unlinked `dirs` crate
- **Content Security Policy** — replaced `null` CSP with a proper baseline policy allowing local resources and Google Fonts
- **Canvas dependency** — updated `@blinksgg/canvas` to correct local file path

### Removed
- **Dead code** — removed unused `cache.rs` module (196 lines) that was never compiled (no `mod cache;` declaration, missing `notify` crate dependency)

### Changed
- **README** — replaced Vite template boilerplate with comprehensive project documentation
- **.gitignore** — added `src-tauri/target/` and `vault/` exclusions
- **Version** — bumped from 0.9.0 → 1.0.0 across `package.json`, `Cargo.toml`, and `tauri.conf.json`
