-`obfuscate=`/`hide=` still work as an explicit escape hatch — pass either one (even an
-empty list) and marker scanning is skipped entirely in favor of your own 1-based line
-ranges:
+> [!IMPORTANT]
+> List the **specific** paths your model calls, as above — this is the default-deny posture the
+> tool is built for: everything not named is denied. Avoid broad globs like `jax.*`: they pull in
+> JAX's own host-callback and disk-IO functions (`jax.numpy.save`, `jax.debug.callback`,
+> `jax.experimental.io_callback`, …) that the private region could call to exfiltrate data. If you
+> must use a broad glob, pair it with a `disallow_functions` floor — see
+> [docs/blacklist.md](docs/blacklist.md#optional-disallow_functions).
+
+The private region is designated **only** by `# syft-restrict: ...` comment markers in the
+source; `run()` resolves them and refuses a file that carries none. This is how
+**[examples/gemma_inference.py](examples/gemma_inference.py)** generates its
+obfuscated copy — see [examples/generate.py](examples/generate.py).
+
+Two optional strictness flags, both defaulting to the permissive behavior:
 
 ```python
 result = restrict.run(
     "gemma_inference.py",
-    obfuscate=[[22, 93], [99, 280]],  # 1-based ranges: identifiers renamed, constants blanked
-    hide=[],                          # 1-based ranges: whole line replaced with ■■■■■■■■
-    allow_functions=["jax.*", "flax.linen.*"],
+    allow_functions=[...],  # as above
     allow_operators=["arithmetic", "indexing", "comparison"],
+    allow_local_assignments=True,   # False: a local aliased to a callable can't be called by name
+    allow_base_class_attributes=True,  # False: a never-assigned self.<attr> is not presumed inherited
 )
 ```
 
-This is how **[examples/gemma_inference.py](examples/gemma_inference.py)** generates
-**[examples/gemma_inference.obfuscated.py](examples/gemma_inference.obfuscated.py)** —
-see [examples/generate.py](examples/generate.py).
-
-The same model marked up with comment blocks instead of numeric ranges lives in
-**[examples/gemma_inference_marked.py](examples/gemma_inference_marked.py)** /
-[examples/generate_marked.py](examples/generate_marked.py).
-
 If syft-restrict was successfully executed on the true original file, the obfuscated file can be safely shared without exposing the private section.

+### Imports
+
+Imports happen in the public region but govern what the private region may
+reach:
+
+- **Public imports are unchecked.** Any module may be imported in public code;
+  syft-restrict never restricts or inspects the import itself.
+- **Private imports are banned outright** — an `import` inside the private
+  region is rejected as `banned-construct`.
+- **The private region's _use_ of an import is what's gated.** A private call
+  like `jnp.einsum(...)` resolves through the public import table and must match
+  `allow_functions` (see below); otherwise it fails. So the control point is the
+  private-side call, not the public import.
+
+Star imports (`from jax import *`) are disallowed everywhere, because they make
+it impossible to review the imported names.

-The policy here lists the *exact* lower-level JAX/Flax symbols the private region uses,
-rather than broad globs (`jax.*`). Each call leaf (`jax.numpy.einsum`, …) is enforced
-individually; `jax.lax` / `jax.nn` are included only because the calls are written as
-deep attribute paths (`jax.lax.rsqrt`), so the checker also evaluates those module
-references. `jax.numpy` needs no such entry — it's aliased as `jnp` (a bare name).
-
-OBFUSCATE keeps structure legible (identifiers renamed, constants blanked); HIDE replaces
-whole lines with a ■■■■■■■■ marker. The verified region is their union.
+The model carves out its own private region with `# syft-restrict: ...` comment markers, so
+run() resolves the region straight from the source — this is the supported UX. (The
+generate_ranges.py / gemma_inference_ranges.py variant drives the same model through explicit

+entry point with hand-counted ranges instead, exercising that path.

+The policy here lists the *exact* lower-level JAX/Flax symbols the private region uses,
+rather than broad globs (`jax.*`). Each call leaf (`jax.numpy.einsum`, …) is enforced
+individually; `jax.lax` / `jax.nn` are included only because the calls are written as
+deep attribute paths (`jax.lax.rsqrt`), so the checker also evaluates those module
+references. `jax.numpy` needs no such entry — it's aliased as `jnp` (a bare name).
