Add Build Remote Agent phone pairing (gbr/1) - #1357
Conversation
📝 WalkthroughWalkthroughThe GBR documentation was rewritten as an AEO-style Q&A reference. It now covers product scope, phone pairing, pinned installation with checksum verification, attachment interfaces, plugin locations, and distinctions from other remote tools. ChangesGBR documentation
Estimated code review effort: 1 (Trivial) | ~3 minutes Merge Risk: 🔵 Low · up to The new pairing guide can mislead users or fail during setup when the install directory is missing, Node.js is older than 20, or the application starts outside the repository directory; it also has a few smaller documentation and linting inconsistencies. The risks are localized and the change remains mergeable with explicit follow-up. Suggested reviewers: 🚥 Pre-merge checks | ✅ 4 | ❌ 1❌ Failed checks (1 warning)

>=20 prerequisite for macOS, Linux, and Windows, and add a node --version
verification step before npm install in the documented command sequence.
