+
+## No “magic strings” in Rust UI or save logic
+
+This repo intentionally avoids sprinkling important string literals throughout the Rust code, because typos like `"publicOpinon"` won’t fail at compile time.
+
+### Use `tise2/src/statics.rs` for constants
+
+- **UI strings** go in `tise2/src/statics.rs` with an `EN_` prefix.
+  - Example: `EN_BTN_OPEN`, `EN_WINDOW_ABOUT`, `EN_PUBLIC_OPINION_HELPER`.
+  - In code, use `statics::EN_*` rather than inline `"Open…"`, `"About"`, etc.
+
+- **Terra Invicta save-structure keys** go in `tise2/src/statics.rs` with a `TI_` prefix.
+  - Example: `TI_PROP_PUBLIC_OPINION`, `TI_PUBLIC_OPINION_UNDECIDED`, `TI_GAMESTATES`, `TI_REF_FIELD_VALUE`, `TI_REF_FIELD_TYPE`.
+  - In code, use `statics::TI_*` rather than inline `"publicOpinion"`, `"Undecided"`, `"gamestates"`, `"value"`, `"$type"`, etc.
+
+### What to do when adding/editing features
+
+- If you need a new UI label/heading/button text: **add an `EN_*` const** in `tise2/src/statics.rs`, then reference it from the UI.
+- If you need a new key/property name for parsing/formatting TI saves: **add a `TI_*` const** in `tise2/src/statics.rs`, then reference it everywhere.
+- Prefer compile-time string reuse over retyping literals in `gui.rs`, `save.rs`, `value.rs`, tests, etc.
+
+### Validation expectations
+
+- Keep changes minimal and consistent with existing style.
+- Before considering work “done”, run:
+  - `cargo fmt --all`
+  - `cargo clippy --all-targets -- -D warnings`
+  - `cargo test`
