+# Changelog
+
+All notable changes are documented in this file. Gridnote follows [Semantic Versioning](https://semver.org/) for public releases where practical.
+
+## [0.1.0] - 2026-07-13
+
+### Added
+
+- Local TXT and non-DRM EPUB import, parsing, search, bookmarks, and persistent reading locations.
+- Original office-style phone-rental data workspace with formula-bar reading presentation.
+- Floating reader, Super Stealth mode, configurable appearance, progress indicator, and menu-bar controls.
+- Default shortcut profile: `F7` previous, `F8` next, and `F9` show or hide the floating reader.
+- Per-book aliases, local workbook titles, dense synthetic office templates, and privacy shielding when the app loses focus.
+- Source-available non-commercial license and commercial-licensing path.
+
+### Changed
+
+- Office formula-bar navigation and the floating reader now synchronize reading progress in both directions.
+- The office workspace uses an original presentation and does not expose book text inside spreadsheet cells.
+
+### Known Limitations
+
+- PDF, cloud sync, network features, accounts, DRM handling, XLSX compatibility, notarization, and global shortcuts are not included.
+
+[0.1.0]: https://github.com/ZOB2077/Gridnote/releases/tag/v0.1.0

+- Protect private reading material, personal data, and security-sensitive details.
+
+## Unacceptable Behavior
+
+- Harassment, hateful conduct, intimidation, or unwanted sexual attention.
+- Publishing private information without permission.
+- Submitting malicious code, pirated material, DRM-circumvention tools, or content intended to bypass platform protections.
+
+## Enforcement

+# Contributing To Gridnote
+
+Thank you for improving Gridnote. Contributions are reviewed for product fit, privacy impact, maintenance cost, and compatibility with the source-available license.
+
+## Before You Start
+
+- Read [PRODUCT_SPEC.md](PRODUCT_SPEC.md), [ARCHITECTURE.md](ARCHITECTURE.md), and [AGENTS.md](AGENTS.md).
+- Search existing issues and pull requests before opening a new one.
+- Discuss substantial features in an issue before implementation. Keep pull requests narrowly scoped.
+- Do not add networking, analytics, DRM handling, private APIs, or office-suite trademark assets.
+- Use synthetic fixtures only. Never commit real business data, private books, customer records, or screenshots containing them.
+
+## Development Setup
+
+1. Fork and clone the repository.
+2. Open `Gridnote.xcodeproj` in Xcode 27 beta.
+3. Select the `Gridnote` scheme and run it on macOS.
+4. Run the unit-test command from the README before submitting a pull request.
+
+## Pull Request Expectations
+
+- Describe the user-visible behavior and technical approach.
+- Add or update unit tests for changed business logic.
+- Keep parser, persistence, and UI responsibilities separate.
+- Update documentation when behavior, shortcuts, support boundaries, or release status change.
+- Do not include build products, DerivedData, local test fixtures containing private material, or unrelated formatting churn.
+
+## Commit Style
+
+Use concise imperative subjects, such as `Synchronize office and floating reader progress`. Prefer one logical change per commit when practical.
+
+## Contributor License Grant
+
+By submitting a contribution, you confirm that you have the right to submit it and agree to the contribution terms in [LICENSE](LICENSE), including the copyright holder's right to use and commercialize accepted contributions as part of Gridnote.
+
+## Reporting Problems
+
+Use the bug-report template for reproducible defects. Do not include book contents, personally identifiable information, or private source files in public issues. Security-sensitive reports must follow [SECURITY.md](SECURITY.md).

-# Gridnote Codex Starter Pack
+# Gridnote
 
-This package is the implementation baseline for `Gridnote`, a source-available, local-first macOS novel reader with an office-style spreadsheet disguise. It contains the product and architecture contract plus the initial Xcode project skeleton for Codex-driven implementation.
+[![macOS CI](https://github.com/ZOB2077/Gridnote/actions/workflows/ci.yml/badge.svg)](https://github.com/ZOB2077/Gridnote/actions/workflows/ci.yml)
+![Platform](https://img.shields.io/badge/platform-macOS%2026%2B-111111)

+![License](https://img.shields.io/badge/license-source--available%20non--commercial-2F855A)
 
-The package is deliberately narrow:
+> A local-first macOS reader with an original office-workspace presentation and a privacy-focused floating reader.
 
-- Personal Mac use only.
-- Local files only.
-- Supported input formats in MVP: `TXT` and `EPUB`.
-- Implementation baseline: `Swift 6`, `SwiftUI`, `SwiftData`, and `AppKit` only where macOS-specific behavior requires it.
-- No networking, cloud sync, telemetry, DRM handling, online bookstores, or full spreadsheet compatibility in MVP.
+Gridnote keeps books, reading progress, aliases, bookmarks, and settings on the Mac. Its primary workspace resembles a compact data workbook populated exclusively with synthetic demo records, while the floating reader provides a minimal, resizable reading surface for short sessions. It is designed for personal reading, not as an Excel replacement or a content distribution service.
 
-## Included Files
+**Status:** `v0.1.0` personal-Mac preview. The application is functional, but distribution signing and notarization are not complete.

+## Highlights
 
-## How To Use
+- Local TXT and non-DRM EPUB import. TXT decoding supports UTF-8, UTF-16, GB18030, and common fallback encodings.
+- Persistent reading location, full-text search, bookmarks, chapter navigation, and per-book aliases.
+- A dense, original office workspace containing synthetic demo data, with novel excerpts shown in the formula bar rather than the grid.
+- Floating reader with page-based layout, transparency controls, reading-progress indicator, edge snapping, and an optional borderless Super Stealth mode.
+- Bidirectional progress sync: navigating in the office formula bar or floating reader continues from the same location.
+- Configurable shortcut profile. Defaults are `F7` previous, `F8` next, and `F9` show or hide the floating reader.
+- No accounts, networking, analytics, cloud sync, DRM removal, or online catalog.
 
-1. Treat `AGENTS.md` as the standing instruction file that Codex reads before every task.
-2. Treat `PRODUCT_SPEC.md` as the source of truth for user-facing behavior.
-3. Treat `ARCHITECTURE.md` and `DECISIONS/0001-architecture.md` as the source of truth for code structure and technical boundaries.
-4. Execute tasks in `TASKS.md` in order unless a later document explicitly permits parallel work.
-5. Open `Gridnote.xcodeproj` in Xcode and continue with the next incomplete task after verifying the current baseline.
+## Requirements
 
-The project targets macOS `26.0`, uses Swift `6.0`, and is configured against the locally available macOS `27.0` SDK. The current implementation covers local TXT/EPUB import and reading, progress restoration, a searchable library, a lightweight spreadsheet-style office shell, and a menu-bar-controlled floating reader. PDF is intentionally unsupported.
+- macOS 26 or later.
+- Apple Silicon is the currently packaged release architecture.
+- Xcode 26 or later. Local release verification currently uses Xcode 27 beta.
 
-## Implementation Status
+## Install
 
-Tasks 001 through 012 are complete. The MVP includes local TXT and EPUB reading, progress restore, an alias-first library, a lightweight office disguise, workspace switching, a transparent floating reader, menu bar controls, settings, offline release fixtures, and release-readiness documentation.
+Download the latest `Gridnote-macOS.dmg` or `Gridnote-macOS.zip` from [Releases](https://github.com/ZOB2077/Gridnote/releases). Move `Gridnote.app` to Applications and open it.
 
-Manual visual verification was completed on macOS 27 after Task 009. The visible hierarchy reads as a credible office data sheet at normal window size, and no Microsoft trademarks or proprietary assets are used.
+The preview build is ad-hoc signed, not notarized. If macOS blocks the first launch, use Finder's **Open** action or allow the app in **System Settings > Privacy & Security**. Do not bypass Gatekeeper for builds from untrusted sources.
 
-Task 010 manual and UI verification confirmed focused shortcut switching, office return behavior, reading-position continuity, and the generic `Operations Dashboard.xlsx` window title.
+## Use
 
-Final verification includes 33 passing unit tests and 9 macOS UI automation tests. UI tests explicitly terminate every launched app instance so settings, reader, floating-reader, and relaunch flows do not leave the test runner waiting on a stale application.
+1. Launch Gridnote. The default surface is the office-style data workspace.
+2. Select the library icon and import a TXT or EPUB file.
+3. Open the floating reader from the toolbar or use `F9`.
+4. Navigate with `F7` and `F8`. When the floating reader is hidden, the same shortcuts move the formula-bar excerpt while Gridnote is focused.
+5. Enable Super Stealth mode in settings when only text should be visible. Its display width and height can be adjusted down to a single line.
 
-## Recommended Working Order
+The office workspace is intentionally limited to presentation and lightweight cell editing. It does not claim XLSX compatibility or implement Excel formulas, macros, or import/export.
 
-1. Bootstrap the macOS project and test targets.
-2. Establish domain models and persistence.
-3. Implement file import and bookmark-based file access.
-4. Implement the canonical text pipeline for `TXT` and `EPUB`.
-5. Add the standard reading experience.
-6. Add the office shell and disguise-specific reading presentation.
-7. Finish hardening, tests, and packaging.
+## Build From Source
 
-## Repo Discipline
+```bash
+git clone https://github.com/ZOB2077/Gridnote.git
+cd Gridnote
+open Gridnote.xcodeproj
+```
 
-- Do not widen scope during implementation.
-- Do not add third-party dependencies in MVP without an explicit architecture decision.
-- Do not copy Microsoft trademarks, icons, or proprietary visual assets.
-- Do not build a fake "Excel clone". Build a credible original office-like shell with limited editing.
+Or build from Terminal with the configured Xcode:
 
-## License And Commercial Use
+```bash
+DEVELOPER_DIR=/Applications/Xcode-beta.app/Contents/Developer \
+xcodebuild -project Gridnote.xcodeproj -scheme Gridnote \
+  -destination 'platform=macOS,arch=arm64' build
+```
+
+Run the unit test suite:
+
+```bash
+DEVELOPER_DIR=/Applications/Xcode-beta.app/Contents/Developer \
+xcodebuild -project Gridnote.xcodeproj -scheme Gridnote \
+  -destination 'platform=macOS' -parallel-testing-enabled NO \
+  -skip-testing:GridnoteUITests test
+```
+
+UI automation is intentionally excluded from the default command because macOS can request local permissions during test launches. See [TEST_PLAN.md](TEST_PLAN.md) for manual verification guidance.
