+## Extracted Crates
+
+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::*`.

+# ironclaw_safety Fuzz Targets
+
+Fuzz testing for the `ironclaw_safety` crate using [cargo-fuzz](https://github.com/rust-fuzz/cargo-fuzz) (libFuzzer).
+
+## Targets
+
+| Target | What it exercises |
+|--------|-------------------|
+| `fuzz_safety_sanitizer` | Prompt injection pattern detection (Aho-Corasick + regex) |
+| `fuzz_safety_validator` | Input validation (length, encoding, forbidden patterns) |
+| `fuzz_leak_detector` | Secret leak detection (API keys, tokens, credentials) |
+| `fuzz_credential_detect` | HTTP request credential detection |
+| `fuzz_config_env` | SafetyLayer end-to-end (sanitize, validate, policy check) |
+
+## Setup
+
+```bash
+cargo install cargo-fuzz
+rustup install nightly
+```
+
+## Running
+
+```bash
+cd crates/ironclaw_safety
+
+# Run a specific target (runs until stopped or crash found)
+cargo +nightly fuzz run fuzz_safety_sanitizer
+
+# Run with a time limit (5 minutes)
+cargo +nightly fuzz run fuzz_leak_detector -- -max_total_time=300
+
+# Run all targets for 60 seconds each
+for target in fuzz_safety_sanitizer fuzz_safety_validator fuzz_leak_detector fuzz_credential_detect fuzz_config_env; do
+    echo "==> $target"
+    cargo +nightly fuzz run "$target" -- -max_total_time=60
+done
+```
+
+## Seed Corpus
+
+Each target has a seed corpus in `corpus/<target>/` with representative inputs covering the major pattern families. The fuzzer uses these as starting points for mutation.

 ## Targets
 
 | Target | What it exercises |
 |--------|-------------------|
-| `fuzz_safety_sanitizer` | Prompt injection pattern detection (Aho-Corasick + regex) |
-| `fuzz_safety_validator` | Input validation (length, encoding, forbidden patterns) |
-| `fuzz_leak_detector` | Secret leak detection (API keys, tokens, credentials) |
 | `fuzz_tool_params` | Tool parameter and schema JSON validation |
-| `fuzz_config_env` | SafetyLayer end-to-end (sanitize, validate, policy check) |
