Release summaries

fresh-toes-build
Pass Bun transpile paths through production JSX mode so published browser bundles stop emitting the dev runtime.
maintainer
Shared Bun transpile paths now force production JSX mode, and the affected published browser bundles were rebuilt against that fix.
integrator
Browser-facing Contractspec packages no longer publish `react/jsx-dev-runtime` imports in their production JS artifacts.
customer
Production React bundles built from the affected Contractspec packages stop depending on the development JSX runtime.
native-publish-closure
Harden published cross-platform UI packages around precise public subpath imports and closed native dist graphs.
maintainer
Native builds now include generic shared entries in dist/native so native public exports have a resolvable helper closure.
integrator
Cross-package UI imports should use precise public subpaths instead of root design-system imports when published packages may be consumed through platform conditions.
platform-suffix-bun-build
Support ios, android, native, and web platform suffixes in the shared Bun build tool and Metro presentation helper.
maintainer
contractspec-bun-build now treats ios and android as native-family platform variants while keeping web and native export behavior stable.
integrator
Packages can publish .ios, .android, .native, and .web source variants with matching conditional exports and build outputs.
customer
Cross-platform UI packages can resolve platform-specific variants more reliably in Expo, React Native, and Next.js projects.

Migration guide

Upgrade to the rebuilt package versions
Pull the patch releases for the affected Contractspec React/browser packages.
When: When a downstream Next or React production bundle was failing on `jsxDEV` paths from published Contractspec packages.
1. Upgrade the affected Contractspec package versions after this release is published.
2. Rebuild the downstream production bundle so it picks up the republished artifacts.
Prefer precise design-system subpaths for published UI packages
Required
Replace root design-system imports in published UI modules with exact public component subpaths.
Regenerate package exports for platform variants
Required
Run contractspec-bun-build prebuild in packages that add or rename .ios, .android, .native, or .web source entries.

Upgrade steps

Verify production bundles no longer import the dev JSX runtime
manual
Check released JS artifacts for `react/jsx-dev-runtime` imports or `jsxDEV(` call sites.
Packages: @contractspec/tool.bun, @contractspec/bundle.marketing, @contractspec/lib.accessibility, @contractspec/lib.contracts-runtime-client-react, @contractspec/lib.design-system, @contractspec/lib.example-shared-ui, @contractspec/lib.presentation-runtime-react, @contractspec/lib.surface-runtime, @contractspec/lib.ui-kit, @contractspec/lib.ui-kit-web, @contractspec/lib.ui-link, @contractspec/lib.video-gen, @contractspec/module.builder-workbench, @contractspec/module.examples, @contractspec/module.execution-console, @contractspec/module.mobile-review
1. Rebuild the affected package set with the updated `@contractspec/tool.bun`.
2. Scan `dist/` output for `react/jsx-dev-runtime` imports and `jsxDEV(` call sites before publishing.
Rebuild packages with native-family entries
manual
Run contractspec-bun-build prebuild and build so dist/native includes shared generic helper files.
Packages: @contractspec/tool.bun, @contractspec/lib.design-system, @contractspec/module.ai-chat
1. Rebuild packages that publish .native, .ios, or .android source variants.
2. Restart Metro after upgrading packages with changed native publish artifacts.
Restart Metro after platform export changes
manual
Metro may cache previous package export maps and should be restarted after upgrading packages that add platform variant exports.
Packages: @contractspec/tool.bun, @contractspec/lib.presentation-runtime-core
1. Stop the Expo or React Native dev server.
2. Restart Metro after package exports have been regenerated and rebuilt.
