Summary

Prepare Kun v0.2.27 for release by merging the validated develop line into master.

This release expands the local-first creative workflow with Kun Video Editor, Kun PPT / Presentation Studio, Design Motion and inline component prototypes, while improving the Code workbench, Write workflows, data migration foundations, Extension media APIs, UI Plugin presentation themes, and Kun runtime stability.

Changes

Add the bundled Kun Video Editor, Presentation Studio, and Social Media Sidebar workflows.
Add Design Motion, inline component prototypes, and richer generated-artifact previews.
Rework the Code right-side tab workbench and improve steering, queued model changes, subagents, and reasoning UI.
Improve Write draft safety, file-scoped context, previews, selection behavior, and focus mode.
Add feature-gated cross-device data migration with trusted-workbench IPC enforcement.
Expand Extension media, job, FFmpeg, artifact, Webview, and workspace-isolation contracts.
Add declarative host-owned UI Plugin portrait presentation with static-image validation and responsive layout safeguards.
Harden runtime approvals, replay, MCP schema stability, credential isolation, telemetry, packaging, and release gates.
Add the complete release notes in release/release-v0.2.27.md.

Release blocker fixes

Restrict data-migration IPC to the current trusted main workbench frame.
Fix UI Plugin portrait preview, z-order, readability, and Composer-overlap regressions.
Align packaged Extension and Video Editor smoke tests with current workspace grants and tab lifecycles.
Stabilize real child-process media tests under the release gate.
Update vulnerable direct dependencies and regenerate Extension API documentation.

Validation

npm run lint -- --quiet
npm run typecheck
npm run test — 4,440 root tests passed
npm --prefix kun test — 2,091 Kun tests passed
Extension public release gate — 97 contract tests passed
npm run build
macOS arm64 packaging, DMG/ZIP integrity, architecture, and deep code-signature verification
Packaged Extension contract and desktop Chromium smoke tests
Packaged Kun Video Editor native sidecar and desktop E2E smoke tests
Dependency audit: no high or critical findings in the reviewed dependency trees

Release notes

See release/release-v0.2.27.md for the full user-facing changelog.

Final distribution requirements

Formal distribution artifacts still need Release CI signing/notarization for macOS, Windows/Linux packaging, drawtext-capable burned-caption evidence, and cross-platform data-migration sign-off.
