RCIP 2.0.3 — React starter and discovery

RCIP 2.0.3 makes the existing React capability runtime easier to find, try, and integrate. Runtime behavior, public APIs, and protocol 1.0 are unchanged.

• Standalone React/TypeScript starter with discovery, current-state reads, input validation, confirmed writes, decline, and cancellation. Copy the directory or download the source-only ZIP below.
• Expanded agentic UI, frontend tools, in-app agent, and browser-use metadata and guidance. External browser agents still need an application-selected bridge; MCP/WebMCP adapters and generic discovery remain future work.
• An llms.txt documentation map and a 71-second captioned walkthrough of the deterministic demo.

The starter pins the already verified npm release 2.0.2 so it is reproducible independently of this release's publication. RCIP 2.0.3 has the same runtime/API behavior. The starter is not a separate npm package.

Validation: package/type/build checks, React 18/19 packed consumers, 25 composed browser scenarios, three site checks, and an isolated install/build/browser check of the standalone starter. GitHub CI also checks Node 20, 22, and 24. The release workflow verifies the exact published npm version after upload.

The video shows a local production build of the reference demo at original interaction speed, with explanatory captions. It uses a deterministic adapter and no AI service, external browser-agent integration, or model benchmark. Captions are burned into the MP4 and available separately as WebVTT. The ZIP contains only the starter's source, lockfile, and license; install dependencies with npm ci.

Existing public monitoring keeps its original expiry: 2026-09-24T21:00:04Z.
