+# DataFog Core repository rules
+
+## Correctness
+
+- Detection changes require positive and negative tests that prove the changed behavior.
+- Do not silently discard fallible results.
+- Avoid panic paths for user-controlled input.
+- Preserve documented entity offset semantics across the Rust core and all bindings.
+
+## Structure
+
+- Add files only for distinct logical components.
+- Do not introduce abstractions without a demonstrated need in the current codebase.
+- Keep bindings thin: PII detection semantics belong in `crates/core`.
+- Do not duplicate detector logic in Python, Node, or WASM bindings.
+- Do not perform unrelated refactoring while implementing a scoped change.
+
+## Code
+
+- Comments document public behavior or explain non-obvious reasoning; do not narrate syntax.
+- Prefer descriptive names over abbreviations.
+- New third-party dependencies require a concrete need that cannot be met reasonably with the standard library or existing dependencies.
+
+## Changes
+
+- Keep each pull request focused on one behavior or maintenance goal.
+- Run `cargo fmt --all --check`, `cargo clippy --workspace --all-targets --all-features -- -D warnings`, and `cargo test --workspace --all-features` before merging Rust changes.
