# Antigravity Context Ring

> Native inline context window telemetry & 256K physical truncation monitor for Google Antigravity Desktop App.

## Overview
Antigravity Context Ring provides real-time token telemetry for the Google Antigravity Desktop App. It reads directly from local Language Server Connect-RPC snapshots, displaying context consumption against the client's 256K auto-compaction threshold via a non-invasive 19px inline ring widget.

## Key Technical Specifications
- Ground-Truth Telemetry: Connect-RPC modelUsage parsing including input, output, and cache read/creation tokens without character approximations.
- Truncation Baseline: Aligned with the 256K physical auto-compaction boundary of the desktop client.
- Integration Method: Chrome DevTools Protocol (CDP) injection; zero modification to binary or resources/app.asar.
- Concurrency & Isolation: Pane-level React Fiber binding prevents cross-talk across Split View composers; UI-selected model solely determines denominator capacity.
- Overhead: Constant ~18MB Node.js process memory footprint, near-zero idle CPU.
