Summary

Upgrade all six applications maintained in this repository to Meteor 3.6-rc.1 and Rspack 2:

• Complex Todos (Svelte)
• NFT Marketplace
• Notes Offline
• Parties
• Task Manager
• Tic-Tac-Toe

Each app selects the published Meteor release and its corresponding package versions. The npm manifests and lockfiles use @meteorjs/rspack 3.0.0-rc.2, with dependency floors matching the release: Rspack core/CLI 2.2.7, dev server 2.2.1, and SWC 1.16.2. React examples also use the required React Refresh versions. Normal startup supports Meteor's automatic build-dependency installation.

The root and application READMEs, Svelte About screen, and generated examples catalog reflect the RC. External examples retain their independently maintained versions.

Compatibility updates

• Use native Meteor TypeScript declarations in Complex Todos, Task Manager and Tic-Tac-Toe, with a typecheck command for each. Notes Offline uses native declarations for JavaScript editor support.
• Update Svelte and its application types and bindings for the current Skeleton and build toolchain.
• Update Notes Offline's Lingui SWC plugin for the compiler used by Rspack 2.
• Include the Task Manager meteor-rpc compatibility patch and type assertions for the native declarations.

Validation

Executed locally with the published Meteor 3.6-rc.1 release, Node.js 26.12.1 and npm 11.20.0:

• meteor update --release 3.6-rc.1 and npm dependency installation passed for all six apps.
• meteor npm run typecheck passed for Complex Todos, Task Manager and Tic-Tac-Toe. Svelte reported zero errors and zero warnings.
• All 51 existing browser tests passed: Tic-Tac-Toe 6, Notes Offline 13, Parties 8, Task Manager 9, and Complex Todos 15. Browser retries were disabled, and the existing test sources were unchanged.
• NFT Marketplace: compiled its Solidity contracts, built a production bundle, started it with a temporary local MongoDB, and verified that its wallet-installation screen renders without browser errors.
• The generated examples catalog is synchronized, and git diff --check passes.

Browser validation used SockJS because this host cannot load the Node 26 uWebSockets binary requiring GLIBC_2.38. Polling was enabled to work around the host's exhausted file-watcher limit. These verification overrides were kept outside the committed application settings. NFT wallet transactions and external blockchain/IPFS integrations were not exercised.

The existing paused CI jobs remain unchanged; the checks above were run locally.
