 ## Validation
 
 Run actionlint for workflow changes and test a pinned workflow from a consumer.
+
+## Code Review Rules
+
+### Shared policy and ownership
+
+- Flag shared policy that fixes a package-specific version, platform window or
+  toolchain outside the owning package. Safe path: derive variable values from
+  caller configuration and state only the shared invariant here.
+
+### Workflow compatibility
+
+- Flag a reusable workflow interface change without a compatible caller path
+  and consuming-repository evidence. Safe path: validate the pinned workflow
+  in a caller and document the adoption requirements.
+
+### Claims and release integrity
+
+- Flag an acceptance or release claim without evidence for the identified
+  source, or instructions that could replace an immutable published identity.
+  Safe path: report the actual validation state and follow `VERSIONING.md`.

+# Organization avatar sources

+[DESIGN.md](../../DESIGN.md#iconography) owns the background, layer order,
+and material settings. `Bird.svg` and `Dots.svg` are flat source layers for
+Icon Composer; native effects and masks are applied during generation.
+
+The Swift bird is supplied brand artwork from
+[Swift.org](https://www.swift.org/assets/images/swift.svg), positioned on a
+transparent canvas. Swift and the Swift logo are trademarks of Apple Inc.
+The dot field, native material treatment, and organization palette belong
+to this avatar composition. This artwork is not used as a package glyph or
+as a generic icon skill example.
+
+Generate the `swift-library` app entry with `apple-app-icon-design`, review
+all native appearances and the web set, and verify drift before replacing
+delivered assets. Repository README and documentation logos use the separate
+framework-style entry in the same design document.
