Account and runs
Run the Python reference engine on the LunarHaul service, keep every run with the exact code, data and seeds that produced it, re-run it to check that it replicates, and publish it to the gallery. You can start runs without signing in; an account keeps them together and lets you publish. Nothing else on the site needs an account.

What a run record holds
The engine version and git commit (and whether the code had uncommitted changes), the Python and platform, the scenario and its hash, the seeds, the hashes of every data file the engine read (landing-outcome tables, driving tables, terrain), and the hash of the output. Replicating re-runs the stored inputs and compares output hashes, so “replicated ✓” means the same bytes came out. Only runs of a clean, tagged release rank on the leaderboard.
