What's Wrong?

I was coding using Claude Terminal with 4 separate terminal sessions open. Each terminal had its own dedicated context provided through separate .md files.

However, after compacting , continuing work from Terminal 1, Claude unexpectedly picked up the context from Terminal 4 instead of using the context associated with Terminal 1. When asked it mentioned its received through compacted data.

What Should Happen?

It should have usd its provided context instead of picking up other context.

Steps to Reproduce

Create 4 terminal claude instace
provide seperate context with sperat md files
check after compacting of one of the terminal session
note: I did not do many experiments, but this is what i found, there has to be some cnteext leak between each terminal session while comapcting
