Abstract
We propose to build dpm trace, an open-source DPM plugin for inspecting and debugging Canton transactions. A developer should be able to start from an already committed update id, run a single CLI command, and get a readable transaction trace. From there, the tool adds interactive inspection and source-aware debugging workflows. To make that reliable, we also propose compiler-generated debug metadata so transaction traces and debugger steps can link back to Daml source.
