What's New

Introduces remote Antigravity OAuth helper and CCR retrieval improvements.

New Features

  • Remote Antigravity login via local helper with paste-credentials support.
  • Graceful cert-install fallback for containers and headless environments.
  • CCR retrieval with range, grep, and stats methods for compression engines.
  • TOON best-of-N candidate encoder for compression.
  • Automated ratchet shrink-banking in CI pipelines.

Improvements

  • Safer, more granular access methods for compression engine retrieval.
  • Improved reliability of Agent Bridge in Docker/headless environments.
  • Enhanced OAuth flow specifically for remote VPS deployments.

Bug Fixes

  • Resolves Antigravity OAuth hanging issues on remote VPS deployments.
  • Fixes certificate installation failures in read-only or headless trust stores.

Upgrade Notes

Existing Antigravity OAuth setups on VPSs must switch to the new CLI helper or dashboard paste-credentials field. Compression engine configurations should verify that CCR retrieval methods are compatible with the new range/grep/stats capabilities.
