-## Extracted Crates
+## Internal Shared Sources
 
-Safety logic lives in `crates/ironclaw_safety/`. The `src/safety/mod.rs` shim re-exports everything for backward compatibility, but **new code should import from `ironclaw_safety` directly** (e.g. `use ironclaw_safety::SafetyLayer`). When touching a file that still uses `crate::safety::*`, migrate its imports to `ironclaw_safety::*`.
+The main `ironclaw` crate owns its shared event types and safety layer under `src/common/` and `src/safety/`. The unpublished `ironclaw_common` and `ironclaw_safety` helper crates are internal wrappers around those same source files for workspace-only uses such as fuzzing.
+
+When working inside the main crate, import from the in-crate modules:
+- use `crate::common::{AppEvent, ToolDecisionDto, truncate_preview}`
+- use `crate::safety::*` (for example `use crate::safety::SafetyLayer`)
+
+The standalone helper crates remain for internal workspace uses such as fuzzing, not as the primary import path for the main crate.
