+**NEVER Modify Generated Files Directly**
+
+Files in `src/adcp/types/generated_poc/` are auto-generated by `scripts/generate_types.py`. Any manual edits will be lost on regeneration.
+
+**Post-Generation Fix System:**
+
+We use `scripts/post_generate_fixes.py` which runs automatically after type generation to apply necessary modifications that can't be generated.
+
+**Type Name Collisions:**
+
+The upstream AdCP schemas define multiple types with the same name (e.g., `Contact`, `Asset`, `Status`) in different schema files. These are **genuinely different types** with different fields, not duplicates.
+
+When consolidating exports in `generated.py`, we use a "first wins" strategy (alphabetical by module name) and warn about collisions. Users can still access all versions via module-qualified imports:
+
+```python
+# Access the "winning" version
+from adcp.types.generated import Asset
+
+# Access specific versions
+from adcp.types.generated_poc.brand_manifest import Asset as BrandAsset
+from adcp.types.generated_poc.format import Asset as FormatAsset
+```
+
+**Upstream Issue:** This should ideally be fixed in the AdCP schema definitions by either:
+- Using unique names (e.g., `BrandAsset` vs `FormatAsset`)
+- Sharing common types via `$ref`
+- Using discriminated unions where appropriate
+
+**Current fixes applied:**
+1. **Model validators** - Injects `@model_validator` decorators into:
+   - `PublisherProperty.validate_mutual_exclusivity()` - enforces property_ids/property_tags mutual exclusivity
+   - `Product.validate_publisher_properties_items()` - validates all publisher_properties items
+
+2. **Self-referential types** - Fixes `preview_render.py` if it contains module-qualified self-references
+
+3. **Forward references** - Fixes BrandManifest imports in:
+   - `promoted_offerings.py`
+   - `create_media_buy_request.py`
+   - `get_products_request.py`
+
+**To add new post-generation fixes:**
+Edit `scripts/post_generate_fixes.py` and add a new function. The script:
+- Runs automatically via `generate_types.py`
+- Is idempotent (safe to run multiple times)
+- Validates fixes were successfully applied
+- Fails loudly if schema changes break the fix patterns
+
 **Type Checking Best Practices**
 - Use `TYPE_CHECKING` for optional dependencies to avoid runtime import errors
 - Use `cast()` for JSON deserialization to satisfy mypy's `no-any-return` checks
