 ## Commit & Pull Request Guidelines
 Write commits in imperative mood (`Add turbine moisture separator model`). Squash small WIP commits before review. Pull requests must describe the scenario, attach log excerpts (`snapshots.json` diff) or plots for novel behavior, and link to any tracking issues. Include validation notes: commands run, expected trends (e.g., outlet temperature increase), and outstanding risks.
+- Agents should automatically create a commit immediately after code/config/text changes are finished; use a clear imperative subject and avoid piling multiple logical changes into one commit unless the task explicitly says otherwise.

Sensitive experiments (e.g., beyond design basis) should default to disabled flags so scripted studies remain safe by default.
