East Asian Calligraphy Workbench v0.7.1

v0.7.1 — Japanese Kanji coverage

This release adds Klee One Regular as an independent modern Japanese handwriting candidate and a small, Japanese-only Source Han Serif JP derived subset as a visibly labelled coverage fallback. Yuji remains the primary calligraphy source; historical CODH samples remain a separate category. Strict Japanese mode never silently substitutes Chinese glyphs.

The reproducible coverage benchmark measures JIS X 0213 Kanji cmap coverage at 6,745/10,051 with Yuji alone and 10,051/10,051 with the combined Japanese library. Jōyō, Jinmeiyō, JIS X 0208 Kanji and the reviewed project corpus are also complete in the combined benchmark. These figures do not claim complete Japanese typography, historical coverage, IVS support or aesthetic correctness.

The fonts are redistributed under SIL OFL 1.1. Their upstream versions, checksums, licences, provenance and reproducible fallback subset recipe are recorded in the source manifests and offline package notices. Existing v0.7.0 projects remain readable; the project schema remains version 2.

Downloads include the Windows x64 installer and portable build, offline Web ZIP, production-signed Android APK, SHA256SUMS.txt and build/signing receipts. All packages come from the same tagged commit. The Windows binaries remain unsigned and may prompt SmartScreen. The Android APK is signed with the persistent release identity; its certificate fingerprint is in the signing receipt and recovery guidance.

Automated browser, API, Windows native renderer, Android build/signature, package and licence checks passed. Physical Android storage/share/lifecycle testing and the Windows installer wizard, shortcuts, upgrade/uninstall and visible IME acceptance remain manual validation gaps.

East Asian Calligraphy Workbench v0.7.0

v0.7.0 — East Asian Calligraphy Workbench

Chinese calligraphy remains supported. Japanese is the first expansion beyond Chinese; other East Asian traditions are not shipped in this release.

• Separate Unicode semantic identity from visual glyph variants and cultural provenance.
• Add five Yuji 3.002 fonts under OFL 1.1, including explicit Akari/Akebono hentaigana variants. Fonts are not historical manuscripts.
• Add HarfBuzz Japanese shaping, mixed kanji/kana and glyph-cell horizontal/vertical composition.
• Add 20 CODH v2 historical crops and attributed ink-mask derivatives under CC BY-SA 4.0; preserve source occurrences and unknown cultural facts. Full corpus remains an optional verified local import.
• Keep Chinese/Japanese candidate traditions isolated by default; cross-tradition exploration is explicit.
• Preserve licence, rights, attribution, Unicode/variant identity and checksums in project and artwork exports.
• Migrate project/database schema v1 → v2; permanent fixtures test semantic and rights integrity across save/reload/export. Back up SQLite/projects before upgrading; downgrade by restoring backups.
• Packages share a canonical asset/third-party manifest, offline licence viewer, version checks and build provenance. No cloud account is required.

Security and release status

Production web/desktop npm and resolved API dependency audits are clean in the recorded audit. Starlette/FastAPI runtime updates fix six unique API advisories; narrow global-agent, PostCSS parser and source-map updates fix additional toolchain findings. Five development dependency findings trace to the unpatched braces stack-exhaustion advisory in Tailwind 3 tooling; they are retained, scoped and documented in docs/DEPENDENCY_AUDIT_0.7.0.md. No vulnerable tooling enters renderer bundles or packaged application dependencies. This does not mean the entire development tree has zero vulnerabilities.

This release publishes the Windows x64 installer, Windows x64 portable executable and offline Web ZIP, with SHA256SUMS.txt, build provenance and signing receipts. Windows binaries are unsigned and may trigger SmartScreen or organisational restrictions.

No Android APK is published for v0.7.0. The Android build and package checks pass locally, but only debug preview signing is available. Production signing and physical Android storage/share/lifecycle acceptance remain outstanding. The automated Windows checks launch the actual unpacked and portable applications; installer wizard, shortcuts, upgrade/uninstall and visible IME acceptance remain unverified. These limitations are disclosed rather than treated as passed.

Conditional signing and verification are documented in signing guidance. A production APK is accepted only with complete private signing configuration and successful signature validation; missing credentials omit Android, and partial credentials fail the release.

Known limitations

Japanese composition is per glyph cell. Full kinsoku shori, advanced punctuation/orientation rules, connected-kana continuity, tate-chū-yoko, arbitrary IVS and comprehensive historical orthography are not implemented. The sample is not complete kuzushiji coverage or proof of historical authenticity. Download resume restarts the download; local import checkpoints are repeatable. Large export ZIPs assemble in browser memory. Canvas/FreeType antialiasing can vary across platforms.

See docs/MIGRATIONS.md, docs/RELEASE_SMOKE_TEST_0.7.0.md and the release-readiness section of docs/IMPLEMENTATION_REPORT_0.7.0.md for exact executed checks, remaining manual tests, package sizes and signing status.

验证

数值测试覆盖特征、骨架、距离变换、拓扑、H0、OT、1000 字边界、分页、beam search、重复变化及取消。生产网页回归覆盖现有工作台，以及 1031 字长卷、缺字留位、ZIP 完整性、实际墨迹与手机布局。

本机 Edge 开发模式测量：1000 个不同汉字排版约 13.43 s，首次特征分析约 3.91 s，缓存复用生成 1001 字长卷约 1.90 s。耗时随设备和字库变化，不是跨设备保证。

使用边界与升级

• 协调度是原始字形与上下文的相近度，不是审美评分，未纳入手动变形与墨色。
• 实验 OT 为投影 1D 距离；持久性为 H0，未实现完整 2D OT 或 H1。
• 长卷结果仅保留在当前会话，刷新前请导出 ZIP；工作台草稿仅存于本机，建议升级前导出 JSON。
• 每字最多分析 8 个候选，beam search 不保证全局最优。大型 ZIP 在内存中组装，实际容量取决于设备。
• Windows 未使用商业代码签名；Android 使用 debug 预览签名，物理设备分享未验证。若 Android 升级遇到签名冲突，先备份后卸载旧版。
• 字库和许可证随包分发，MCCD 等受限数据不包含在发行包中。
