Bug Report: Agent Chat History Not Displaying Despite .pb Files Being Present

Platform: macOS Monterey | MacBookPro12,1 (Early 2015)
Antigravity Version: Latest (prerelease track)
Account Status: Logged in, authenticated

Summary

The Agent chat history panel is completely empty despite 93 conversation .pb files being confirmed present on disk at the expected location (~/.gemini/antigravity/conversations/). The UI is not indexing or displaying any previous conversations.

Steps to Reproduce

  1. Open Antigravity IDE
  2. Open the Agent panel
  3. Chat history sidebar shows no conversations
  4. Confirmed via Terminal: 93 .pb files exist at ~/.gemini/antigravity/conversations/
  5. state.vscdb in globalStorage shows: chat.ChatSessionStore.index | {“version”:1,“entries”:{}}

What I Have Tried

  1. Deleted state.vscdb and workspaceStorage to force re-index — resulted in onboarding loop, no history restored
  2. Used Agent Manager ‘+ Open Workspace’ to re-link project folder — sidebar remained blank
  3. Cleared Service Worker/CacheStorage and Antigravity/Cache — UI cleared but history still missing
  4. Killed and relaunched Antigravity pointing directly at project folder via Terminal
  5. Confirmed Git path fixed (git.path: /usr/local/bin/git), Go extension disabled
  6. Confirmed authentication is active — not showing ‘Authentication Required’

Current State

  • .pb files: 93 files present, file sizes range from ~300KB to ~9.7MB (indicating real conversation data)
  • state.vscdb entries: empty {}
  • Agent panel: open, authenticated, zero history displayed
  • The .pb files appear to be in protobuf binary format and cannot be read manually

Expected Behavior

The Agent panel should scan ~/.gemini/antigravity/conversations/ on launch and display all previous conversations with titles and timestamps.

Actual Behavior

The panel loads successfully but shows zero conversation history despite the files existing on disk.

Request

Please advise on:

  1. How to force the UI to re-index existing .pb conversation files
  2. Whether there is a separate manifest or index file that maps .pb UUIDs to conversation titles
  3. Whether this is a known regression in a recent update

Thank you.
