This repo is a small, stream-friendly demo for one idea:
Same model, same task, different harness, different result.
If you are handing this repo to someone who just needs to run the demo in the right order, start here:
stream/harness_playing/RUN_THIS.md
If they want the slightly more detailed operator version, use:
stream/harness_playing/MATT_RUNBOOK.md
That file is the operator guide with exact setup, exact commands, what should be on screen, and what each step is proving.
