Corresponding source and provenance

The corresponding source for Helper Tools 0.2.0 will be published at:

https://git.add-ideas.de/lotobo/helper-tools/src/tag/v0.2.0

Before that tag exists, the main branch in the same public repository is the preferred source under active review. Build the release with Node.js 22 and the exact dependency graph in package-lock.json:

npm ci
npm run release:artifact

The JavaScript/CSS bundles, npm tarball and generated declarations are outputs, not the preferred form for modification. No runtime code is loaded from a CDN.

Implementation provenance

• The helpers and interface are original TypeScript and React project code.
• Toolbox manifest, shell and artifact checks use the shared Toolbox SDK 0.3.0.
• Encoding formats, IP notation, JSON, CSV, SI/IEC units, Unicode, ISO 8601, checksum and digest algorithms were implemented from public specifications and established interoperable formats; no source from an online calculator is bundled.
• Cryptographic digests and secure randomness use the browser Web Crypto API. The seeded generator is deliberately labelled non-cryptographic.
