# Antigravity Recovery Report

Date: 2026-03-18

## Scope

This document reconstructs usable work history from `~/.gemini/antigravity`.
The `.pb` files under `conversations/` and `implicit/` are not directly readable session text in practice.
For recovery, the reliable source is the matching `brain/<uuid>/` folder that stores Markdown artifacts, metadata, and media.

## Recovery Rule

For each conversation UUID:

1. Use `~/.gemini/antigravity/conversations/<uuid>.pb` only as the session index.
2. Recover content from `~/.gemini/antigravity/brain/<uuid>/`.
3. Prioritize these files when present:
   - `task.md`
   - `implementation_plan.md`
   - `walkthrough.md`
   - `PROJECT_STRATEGY.md`
   - `vla_problem_analysis_professor.md`
   - `directory_audit_20260301.md`
   - `REORGANIZATION_SUMMARY.md`
   - `disk_usage_analysis.md`

## Inventory

- `conversations/*.pb`: 66
- `implicit/*.pb`: 38
- `brain/*` directories: 69

## Other Recoverable Sessions Worth Inspecting

These are older but still contain directly readable source material:

- `4052610b-28d9-4f37-ab61-a0f34e5fbef6`
  - hierarchical VLM + MPC + MCP plan
- `b91ff0ca-0bba-4d8b-a8cf-f111e30bb13e`
  - Korean vs English instruction mismatch fix
- `bba23562-8187-4f86-85de-0f6057205b55`
  - RoboVLMs transfer-learning and instruction-grounding analysis
- `d7c5776d-e3a9-4088-a4d3-b3fcd77b2771`
  - action chunking comparison against RoboVLMs defaults

## Practical Conclusion

For actual recovery work, the recommended order is:

1. Recover Antigravity-only artifacts not present in the repo.
   - `disk_usage_analysis.md`
   - `vla_problem_analysis_professor.md`
   - `directory_audit_20260301.md`
   - `REORGANIZATION_SUMMARY.md`
2. Keep already-reflected sessions as references only.
   - MCP integration plan
   - dataset v3 redesign and timing-memorization analysis
3. Treat `.pb` files as opaque indices, not as the primary recovery format.
