What's Wrong?

I was in the middle of a coding session. Claude had generated code for 3 or 4 of the 5 steps it outlined. I hit my limit and upgraded to Pro, but the session is nowhere to be found.

What Should Happen?

Claude shouldn't lose a coding session when a user upgrades to a Pro plan.

Error Messages/Logs

Used ccd_session_mgmt: search session transcripts
Unfortunately the session isn't in the system at all — it wasn't preserved through the upgrade. This is a real bug and you should report it at github.com/anthropics/claude-code/issues.

The good news: based on the three filenames you remember (geo_connect.py, point_confi.py, rl_environment.py), this looks like a reinforcement learning project with geographic/point cloud components. I can regenerate all four files if you can tell me:

What the project does at a high level
Anything you remember about the fourth file (its purpose, even roughly)
Any specific details or decisions we had made (libraries, APIs, data formats, etc.)
Even a rough description will get us back close to where we were.

Steps to Reproduce

1. Start a coding session with the free plan
2. Hit the limit and upgrade to the Pro plan
3. Lose the session
