I saw scanning the comments and saw you mentioned CRDT. Just wanted to mention that I implemented a CRDT-flavoured sync engine for the product I'm working on a while ago, I think it was with Opus 4.6 if I'm not mistaken (or earlier) so it's not something new to Fable 5, just fyi.

*Problem it solves*: During development, we often need to update auth tokens, API keys, and other headers manually. This extension + companion app creates a live bridge between your local development environment and browser requests.

*How it works*: The browser extension intercepts requests to specified domains and injects custom headers. The standalone desktop app (Electron) provides the dynamic values through WebSockets, watching for changes in source files, environment variables, or handling API requests.

*Technical features*: - JSON path filtering to extract specific values from API responses - TOTP generation for time-based auth tokens - File watching across platforms (macOS/Windows/Linux) - Secure WebSocket communication (WSS for Firefox, WS for Chrome/Edge) - Cross-browser support via browser-specific manifest handling

*Stack*: JavaScript/TypeScript, React, Electron, WebSockets

Looking for feedback/contributors. Happy to answer any questions about implementation details.
