 - Building/unit effects are data-driven from JSON — don't hardcode behavior
 - Always call `DataLoader.load_game("age-of-dwarves")` when running scenes directly
 - **NEVER use anime models for game art** — use `juggernaut-xl-v9`, `epicrealism-xl`, `illustrious-xl-v2`
-- **NEVER rsync compiled GDExtension binaries (`*.so`, `*.dll`, `*.dylib`) from macOS to apricot.** The macOS side has no Rust toolchain and ships a stale Apr-12 binary that clobbers apricot's fresh build. Use `rsync --exclude='addons/magic_civ_physics/*.so'` OR rely on the `.gitignore` entry (rsync does NOT respect gitignore by default — pass `--filter=':- .gitignore'`). Always rebuild via `ssh lilith@apricot.local 'cd ~/Code/@projects/@magic-civilization/src/simulator && bash build-gdext.sh'` after rsyncing Rust source changes. Symptom of this bug: `src/simulator/crates/*.rs` has new code but batch runs show old behavior (e.g. FOOD_PER_POP=2.0 in a binary whose source says 1.5).
 - **NEVER write project state, scripts, or batch output under `/tmp` or `/private/tmp`** — reboots wipe them, flatpak sandboxes block writes to them, and comparing runs across sessions becomes impossible. Canonical locations:
   - Shell scripts/runners → `scripts/` (in-repo, tracked) or `$HOME/bin/` (persistent per-host)
   - Batch/iteration outputs → `.local/batches/` (in-repo, gitignored) or `$HOME/tmp/` (persistent per-host)
