Summary

• Upgrade Nub to 0.9.6, Vite+ to 1.1.0, Vitest to 5.0.3, React to 19.3, Storybook to 10.6.2, MSW to 3, Panda to 2, and the remaining app, initializer, site, and CI dependencies.
• Migrate Park UI slot recipes, Panda presets, MSW worker setup, and the Kahraman preview addon. Keep the demo and generated template in sync.
• Regenerate and deduplicate both lockfiles. Share the Vite+ engine with a Vite override, unify Storybook renderer peer contexts, and remove unused Panda Studio and its legacy dependency tree.
• Invoke the native TypeScript 7 compiler explicitly for the demo and scaffold, retaining the TypeScript 6 library API for tools that still import it.
• Add a generated-project frozen-lockfile regression test and a changeset for create-karkas.

Validation

Full hosted CI passed on the latest head e35c0ab. Both PR checks passed and GitHub reports the branch mergeable.

• Demo interaction/unit suite: 26 files, 416 tests passed, including both V8 coverage executions in the pipeline.
• Initializer suite: 2 files, 14 tests passed, including the generated-project frozen-lockfile check and nine audit-base regression cases.
• Coverage: 97.35% lines, 86.31% branches, 96.87% functions, 96.29% statements. Existing thresholds are unchanged.
• Frozen installation, APM lock consistency, formatting, lint, TypeScript checks, architecture, Fallow audit/dead-code/duplicates/coverage-aware health, all builds, and translation tree-shaking passed.
• Independently generated scaffold: frozen install, dedupe, prepare, formatting, lint, native TypeScript7 check, and production build passed locally.
• Release-only follow-up e35c0ab passed actionlint and input-schema validation against the exact pinned Changesets action. No publish operation was executed locally.

Earlier local full-suite attempts on a memory-constrained VM hit timeouts and cascading Articles data-shape errors. Multiple complete hosted runs passed. V8 coverage, assertions, test timeouts, and coverage thresholds remain enabled and unchanged. Chromium/Node heap limits bound test resource use.

Independent review

• Codex: identified one P2. Bare fallow audit could compare a pushed feature branch with its own upstream and silently analyze zero changed files.

• Fixed in 4070b2f: select the explicit PR/default-branch base, fail clearly when unavailable, and apply the same wrapper in the generated template. Nine regression cases cover both script copies, pushed-feature branches, custom defaults, overrides, and unavailable refs. The real audit still analyzes 81 changed files after push, rather than zero.

• Claude Opus 5.5, via the Claude provider: independently reviewed the overall PR and follow-up, confirmed the P2 is fixed, reproduced the 81-file audit and all nine regression cases, and found no additional confirmed blockers. Its remaining condition, final-head CI passing, is satisfied; the release-only follow-up also passed full CI.

• CodeRabbit: withdrew its Items popup comment after a controlled Chromium comparison: 47/47 passed unchanged, 9 failures after removing the trigger click, and 47/47 after restoration. The source was kept unchanged and the reviewer resolved the thread.

• Copilot: identified the Changesets v2 release input mismatch. Confirmed against the pinned action and fixed in e35c0ab; the review thread is resolved.

Dependency notes

nub dedupe --check passes for the workspace and an independently generated scaffold. Required incompatible transitive major versions remain separate rather than being forced through unsafe overrides.

Summary by CodeRabbit

• New Features
  • Generated projects now include an optional Fallow audit task that checks changes against an available base branch and reports when no base can be found.
• Updates
  • Refreshed development tools and UI libraries in the demo and generated projects, including React, Storybook, Vitest, Panda, and Vite+.
  • Updated generated UI components and Storybook setup for compatibility with the refreshed tools.
  • Improved item filtering interactions in the demo and clarified truncation for long navigation labels.
• Documentation
  • Updated testing and tooling guidance, including where browser-test failure screenshots are saved.

📝 Walkthrough

The pull request updates the demo, generated scaffold, and repository toolchain. It revises Panda and Storybook/MSW integrations, adds Fallow auditing with base-selection tests, and adjusts browser-test memory limits and artifact paths.

Changes: Scaffold and Toolchain Refresh

Layer / File(s)	Summary
Toolchain dependencies and commands .changeset/*, .config/mise/*, .github/workflows/*, apps/demo/package.json, packages/create-karkas/package.json, packages/create-karkas/mise.toml, packages/create-karkas/template/package.json, site/package.json, package.json, docs/tooling.md, packages/create-karkas/src/scaffold.test.ts	Dependency versions, package-manager pins, compiler commands, and CI action pins change across the repository, demo, site, and scaffold. A scaffold test checks that frozen installation does not change the lockfile.
Fallow changed-base auditing .config/mise/conf.d/tasks-quality.toml, .config/scripts/fallow-audit.sh, .github/workflows/test.yml, packages/create-karkas/template/.config/scripts/fallow-audit.sh, packages/create-karkas/template/mise.toml, packages/create-karkas/template/.github/workflows/test.yml, packages/create-karkas/src/fallowAudit.test.ts, docs/tooling.md	The repository and scaffold add audit tasks and scripts that select and validate a base ref before running Fallow. Tests cover base selection and unavailable refs.
Panda recipes and component contexts apps/demo/panda.config.ts, apps/demo/theme/recipes/*, apps/demo/src/shared/components/ui/*, packages/create-karkas/template/panda.config.ts, packages/create-karkas/template/theme/recipes/*, packages/create-karkas/template/src/shared/components/ui/*	Both projects explicitly load Panda presets, update recipe registration, and use defineRecipe for the input recipe. UI components switch to createSlotRecipeContext; the field root props receive an explicit type.
Storybook and MSW integration apps/demo/.storybook/*, apps/demo/public/mockServiceWorker.js, apps/demo/src/app/mocks/browser.ts, apps/demo/src/shared/test/index.ts, apm.yml, apm.lock.yaml, packages/create-karkas/template/.storybook/*, packages/create-karkas/template/src/app/mocks/browser.ts, packages/create-karkas/template/src/shared/test/index.ts	Storybook previews register the Kahraman addon, and the documentation describes addon-managed diagnostics. MSW options and worker request handling change, including request tracking, passthrough headers, error messages, and streamed navigation responses.
Test execution and generated UI behavior apps/demo/mise.toml, apps/demo/vitest.config.ts, apps/demo/src/pages/items/testing.ts, apps/demo/src/widgets/side-nav/ui/SideNavItemContent.tsx, packages/create-karkas/template/mise.toml, packages/create-karkas/template/vitest.config.ts, packages/create-karkas/template/src/widgets/side-nav/ui/SideNavItemContent.tsx, .gitignore, packages/create-karkas/template/_gitignore, docs/testing.md	Browser and coverage tests receive heap limits, screenshot artifacts use the .vitest location, and that directory is ignored. Item filter helpers retry until the popup closes, and the side-nav label uses explicit truncation styles.

Why abortErrorGuard.ts appears binary

The version on main contains a literal NUL byte in the grouping-key string. The PR replaces it with the TypeScript escape \0, preserving the runtime separator. Both the demo and scaffold copies at the PR head contain zero NUL bytes. A scan of all 502 tracked .ts and .tsx files also found no NUL bytes.

GitHub still classifies the diff as binary because of the old blob. Forcing text diffs through .gitattributes worked locally but did not change GitHub's rendering, so that experiment was reverted.

Here is the demo's text diff. <NUL> below represents the old literal zero byte; it is not source text. The scaffold copy has the same change.

🔵 Needs a closer look

The broad toolchain migration warrants human compatibility review, and the confirmed release-action input mismatch must be fixed.
