   1. Work in your own worktree on a branch, with your own `CARGO_TARGET_DIR`. While you work:
      `cargo check` and the tests of the crates you touch (`cargo test -p <crate>`). Commit after
      each working step (a layer that compiles with its tests passing), not one big commit per PR.
+     Every commit lands on `main` as it is, so each one must build and pass its tests and say

   2. When the change is done: review it once with `/simplify`, then `cargo fmt --all` and
      `cargo clippy -p <crate> --all-targets -- -D warnings` for each crate you touched, once.
      Regenerate what your change affects: `docs/features.md` when commands change
      (`cargo run -p modelcraft-cli -- features > docs/features.md`), `docs/oracle.md` when
      oracle cases or solver numerics change (`cargo xtask oracle`).
