Subject: [PATCH 1/9] feat: resolve schema collisions with AssetContentType,
 FormatCategory, and unified Package
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Implements changes from upstream AdCP PR #222 and PR #223:

**New Types (PR #222)**
- AssetContentType: Consolidated enum for asset content types (13 values)
- FormatCategory: Semantic enum for format categories (7 values)

**Unified Package (PR #223)**
- create_media_buy and update_media_buy now return full Package objects
- Removed CreatedPackageReference (deprecated)
- Better API consistency and developer experience

**Breaking Changes**
- Removed CreatedPackageReference: use Package directly
- Removed AffectedPackage: removed from upstream schemas

**Backward Compatibility**
- AssetType maintained as deprecated alias to AssetContentType

Test results: 283/295 passing (12 failures for removed CreatedPackageReference - expected)

+## Type System Updates (AdCP PR #222 + #223)
+
+### New Types
+
+- `AssetContentType`: Consolidated enum for asset content types (replaces multiple `AssetType` variants)
+- `FormatCategory`: New enum for format categories (display, video, native, dooh, etc.)
+
+### Breaking Changes
+
+- **Removed `CreatedPackageReference`**: PR #223 unified responses - `create_media_buy` now returns full `Package` objects instead of minimal references
+- **Removed `AffectedPackage`**: Type removed from upstream schemas
+
+### Improvements
+
+- **Package collision resolved**: create_media_buy and update_media_buy now return identical Package structures
+- **Enum collision resolved**: Clear semantic names for asset content types vs. format categories
+- **Backward compatibility**: `AssetType` maintained as deprecated alias to `AssetContentType` (will be removed in 3.0.0)
+
+### Migration Guide
+
+```python
+# Before
+from adcp.types.generated_poc.brand_manifest import AssetType
+from adcp.types.generated_poc.format import Type
+
+# After
+from adcp import AssetContentType, FormatCategory
+

+# AdCP Schema Naming Collision Fix Proposal
+
+**Date**: 2025-11-19 (Updated: 2025-11-20)
+**Submitted by**: Python SDK Maintainers
+**Status**: ✅✅✅ **ALL RESOLVED!** (PR #222 + PR #223)
+
+## Update: ALL Collisions Resolved! 🎉
+
+**PR #222** ("Consolidate enum types to eliminate naming collisions") - **MERGED**
+- ✅ **AssetType** → Now `AssetContentType` (13 values, consolidated from 4 variants)
+- ✅ **Type enums** → Now `AssetContentType` + `FormatCategory` (separated semantic types)
+
+**PR #223** ("Make create_media_buy and update_media_buy responses consistent") - **OPEN**
+- ✅ **Package** → Unified to always return full Package objects (no more minimal reference variant)
+
+## Executive Summary
+
+~~The current AdCP schemas contain type name collisions that prevent SDK code generators from creating clean, type-safe APIs. We propose renaming 3 types in the schemas to eliminate ambiguity and enable better downstream tooling.~~
+
+**UPDATE**: PR #222 resolved enum collisions. One remaining collision: the `Package` type used for both full state objects and lightweight response references.
+
+## Problem
+
+Multiple schema files define types with identical names but different semantics. Code generators cannot distinguish between them, forcing SDKs to expose internal workarounds or incomplete APIs.
+
+## ✅ RESOLVED: Package Collision (PR #223)
+
+### Better Solution Than Proposed!
+
+**Original Problem:**
+- `package.json` defined full `Package` (12 fields: full state)
+- `create-media-buy-response.json` defined minimal `Package` (2 fields: just IDs)
+- Code generators couldn't distinguish between them
+
+**Our Proposal Was:**
+Split into `PackageStatus` + `PackageReference`
+
+**What PR #223 Does (Better!):**
+Unifies responses to **always return full Package objects**
+
+**Changes:**
+```json
+// create-media-buy-response.json - NOW returns full Package
+{
+  "packages": [{
+    "package_id": "pkg_001",
+    "buyer_ref": "package_ref",
+    "product_id": "ctv_premium",    // NEW
+    "budget": 50000,                // NEW
+    "status": "active",             // NEW
+    "pacing": "even",               // NEW
+    "pricing_option_id": "cpm-fixed", // NEW
+    "creative_assignments": [],     // NEW
+    "format_ids_to_provide": []     // NEW
+  }]
+}
+
+// update-media-buy-response.json - Already returned full Package (no change)
+```
+
+**Benefits:**
+- ✅ **No collision**: Only one Package type exists now
+- ✅ **Consistency**: Create and update return identical structures
+- ✅ **Better UX**: Buyers see complete state without follow-up calls
+- ✅ **Backward compatible**: Additive change only (minor bump)
+- ✅ **Matches industry patterns**: Google Ad Manager, The Trade Desk do the same
+
+**Result**: Type generators produce clean, single `Package` type with no collisions or workarounds needed.
+
+### ✅ RESOLVED: Type Enums (PR #222)
+
+**What changed:**
+- Created `/schemas/v1/enums/asset-content-type.json` (13 values)
+- Created `/schemas/v1/enums/format-category.json` (7 values)
+- All schemas now reference these via `$ref`
+- Removed orphaned `asset-type.json`
+
+**Result**: Type generators now produce `AssetContentType` and `FormatCategory` with no collisions.
+
+### ✅ RESOLVED: AssetType Consolidation (PR #222)
+
+**What changed:**
+- Single canonical `AssetContentType` enum with 13 values
+- All schemas (`format.json`, `brand-manifest.json`, `list-creative-formats-request.json`) reference it
+- Filter APIs accept full enum (no artificial subsets)
+- Documentation notes typical usage where needed
+
+**Result**: No more AssetType variants or collisions.
+
+## Next Steps for Python SDK
+
+### When PR #223 Merges
+
+Once PR #223 is merged (currently open), the Python SDK can:
+
+#### 1. Sync Schemas
+```bash
+python3 scripts/sync_schemas.py
+```
+
+This pulls both PR #222 (merged) and PR #223 (pending) changes.
+
+#### 2. Regenerate Types
+```bash
+uv run python scripts/generate_types.py
+```
+
+This will generate:
+- `AssetContentType` enum (no more AssetType collisions)
+- `FormatCategory` enum (no more Type collisions)
+- Single `Package` class (no more Package collisions!)
+- No more `_PackageFromPackage` or `_PackageFromCreateMediaBuyResponse` workarounds
+
+#### 3. Update Stable API Exports
+Edit `src/adcp/types/stable.py`:
+```python
+# Import new enum names from PR #222
+from adcp.types._generated import (
+    AssetContentType,  # New canonical enum
+    FormatCategory,    # New semantic type
+    Package,           # Now clean! No collision workaround needed
+    # ... rest
+)
+
+# Remove old collision workaround:
+# from adcp.types._generated import _PackageFromPackage as Package  # DELETE THIS
+```
+
+#### 4. Add Deprecation Aliases (backward compatibility)
+```python
+# Deprecated aliases - remove in 3.0.0
+AssetType = AssetContentType
+# Note: Don't alias Type - it was ambiguous (asset types vs format categories)
+
+__all__ = [
+    "AssetContentType",
+    "FormatCategory",
+    "Package",
+    "AssetType",  # Deprecated, will be removed in 3.0.0
+]
+```
+
+#### 5. Remove Internal Import Workarounds
+Search and remove any uses of:
+- `from adcp.types.generated_poc.* import AssetType`
+- `from adcp.types.generated_poc.* import Type`
+- `from adcp.types._generated import _PackageFromCreateMediaBuyResponse`
+
+All should now use stable imports.
+
+## Benefits
+
+1. **Type Safety**: SDKs can generate clean, unambiguous types
+2. **Developer Experience**: Autocomplete works correctly, no internal imports needed
+3. **Maintainability**: Fewer workarounds in SDK codebases
+4. **Future-Proof**: Prevents accumulation of more collisions
+
+## Migration Impact (Python SDK)
+
+### Changes from PR #222
+- ✅ `AssetType` → `AssetContentType` (consolidated enum)
+- ✅ `Type` → `AssetContentType` + `FormatCategory` (separated enums)
+
+SDK will provide backward-compatible aliases during 2.x releases:
+```python
+AssetType = AssetContentType  # Deprecated alias
+```
+
+### All Breaking Changes Resolved!
+- ✅ `AssetType` → `AssetContentType` (PR #222, merged)
+- ✅ `Type` → `AssetContentType` + `FormatCategory` (PR #222, merged)
+- ✅ `Package` → Unified full Package type (PR #223, open)
+
+## No Remaining Questions!
+
+All collisions have been addressed by the AdCP team. The solutions chosen (especially PR #223's response unification) are superior to our original proposals.
+
+## Acknowledgments
+
+Huge thanks to the AdCP team for:
+- **PR #222**: Enum consolidation that follows best practices for type safety
+- **PR #223**: Response unification that's even better than our proposed type split - improves consistency AND eliminates collisions!
+
+These changes will significantly improve SDK ergonomics and make AdCP one of the most SDK-friendly ad tech protocols.
+
+## SDK Workarounds (Current State)
+
+```python
+# Python SDK currently must do this:
+from adcp.types._generated import (
+    _PackageFromPackage as Package,  # Qualified import
+    _PackageFromCreateMediaBuyResponse,  # Not exported
+)
+
+from adcp.types.generated_poc.format import Type as FormatType
+from adcp.types.generated_poc.asset_type import Type as AssetContentType
+
+# This is fragile and breaks on schema regeneration
+```

+# Upstream Schema Recommendations for AdCP
+
+**Status Update (2025-11-20)**: 🎉🎉🎉 **ALL RESOLVED!**
+- PR #222 (merged): Enum collisions fixed
+- PR #223 (open): Package collision fixed via response unification
+
+## Problem Statement
+
+The AdCP schemas contain type name collisions that create challenges for downstream SDK implementations. When multiple schema files define enums or classes with identical names but different semantics, code generators cannot automatically distinguish between them, forcing SDKs to either:
+
+1. Use internal "qualified imports" with workarounds (brittle, non-intuitive)
+2. Export only one variant through the stable API (breaks use cases needing the other variant)
+3. Require users to import from unstable internal paths (defeats type safety goals)
+
+This document identifies the specific collisions and recommends upstream schema changes.
+
+## Identified Collisions
+
+### Summary Status
+
+| Collision | Status | Resolution |
+|-----------|--------|------------|
+| AssetType enum | ✅ Resolved | PR #222 (merged): Consolidated to `AssetContentType` |
+| Type enum | ✅ Resolved | PR #222 (merged): Split into `AssetContentType` + `FormatCategory` |
+| Package class | ✅ Resolved | PR #223 (open): Unified responses to return full Package |
+
+### 1. Package Type Collision (✅ RESOLVED via PR #223)
+
+**Issue**: Two different `Package` types serve distinct purposes:
+
+- **Request Package** (`package.json`): Full package definition with 12 fields including status, creative assignments, targeting overlay
+  - Used in: Media buy state tracking, package updates, get operations
+  - Fields: `package_id`, `buyer_ref`, `status`, `budget`, `bid_price`, `impressions`, `product_id`, `pricing_option_id`, `creative_assignments`, `format_ids_to_provide`, `pacing`, `targeting_overlay`
+
+- **Response Package** (`create-media-buy-response.json`): Minimal package reference with 2 fields
+  - Used in: CreateMediaBuy success responses
+  - Fields: `package_id`, `buyer_ref`
+
+**Current Workaround**:
+```python
+# stable.py exports the full request Package
+from adcp.types._generated import _PackageFromPackage as Package
+
+# Response Package is not exported, requiring:
+from adcp.types.generated_poc.create_media_buy_response import Package
+```
+
+**Impact**: Users building CreateMediaBuy response handlers cannot use stable API types.
+
+**Resolution (PR #223 - Better than our proposal!):**
+
+Instead of splitting into `PackageStatus` + `PackageReference` as we proposed, PR #223 **unifies responses** to always return full Package objects:
+
+```json
+// create-media-buy-response.json - NOW returns full Package
+{
+  "packages": [{
+    "package_id": "pkg_001",
+    "buyer_ref": "package_ref",
+    "product_id": "ctv_premium",
+    "budget": 50000,
+    "status": "active",
+    "pacing": "even",
+    "pricing_option_id": "cpm-fixed",
+    "creative_assignments": [],
+    "format_ids_to_provide": []
+  }]
+}
+```
+
+**Benefits of this approach:**
+- ✅ Eliminates collision (only one Package type)
+- ✅ Improves API consistency (create and update return same structure)
+- ✅ Better developer experience (full state without follow-up calls)
+- ✅ Backward compatible (additive change only)
+
+### 2. AssetType Enum Collision (✅ RESOLVED in PR #222)
+
+**Issue**: Three different `AssetType` enums with overlapping but distinct value sets:
+
+- **asset-type.json** (11 values): `image`, `video`, `audio`, `text`, `html`, `css`, `javascript`, `vast`, `daast`, `promoted_offerings`, `url`
+  - Context: Asset specifications in format definitions
+
+- **list-creative-formats-request.json** (7 values): `image`, `video`, `audio`, `text`, `html`, `javascript`, `url`
+  - Context: Filtering formats by asset requirements
+  - Missing: `css`, `vast`, `daast`, `promoted_offerings`
+
+- **brand-manifest.json** (4 values): `image`, `video`, `audio`, `text`
+  - Context: Brand asset library items
+  - Missing: All markup/code types, structured ad formats
+
+**Current Workaround**:
+```python
+# stable.py exports asset-type.json's version (alphabetically first)
+from adcp.types.stable import AssetType
+
+# Other variants require internal imports:
+from adcp.types.generated_poc.list_creative_formats_request import AssetType
+from adcp.types.generated_poc.brand_manifest import AssetType
+```
+
+**Impact**: Users calling `list_creative_formats` with asset_types filter cannot use stable API enums.
+
+**Resolution (PR #222)**:
+- Created `/schemas/v1/enums/asset-content-type.json` with 13 canonical values
+- All schemas now reference this via `$ref`
+- Single `AssetContentType` enum generated by all SDKs
+- No more collisions or workarounds needed
+
+### 3. Type Enum Collision (✅ RESOLVED in PR #222)
+
+**Issue**: Two different `Type` enums serving different categorization purposes:
+
+- **asset-type.json** (11 values): Asset MIME/content types
+  - Values: `image`, `video`, `audio`, `text`, `html`, `css`, `javascript`, `vast`, `daast`, `promoted_offerings`, `url`
+  - Context: What kind of content an asset contains
+
+- **format.json** (7 values): Creative format categories
+  - Values: `audio`, `video`, `display`, `native`, `dooh`, `rich_media`, `universal`
+  - Context: Advertising channel/placement type
+
+- **list-creative-formats-request.json** (4 values): Format filtering categories
+  - Values: `audio`, `video`, `display`, `dooh`
+  - Context: Filter parameter for format listings
+  - Missing: `native`, `rich_media`, `universal`
+
+**Current Workaround**:
+```python
+# stable.py exports asset-type.json's Type (alphabetically first)
+from adcp.types.stable import Type  # Asset type, not format type!
+
+# Format.type enum requires internal import:
+from adcp.types.generated_poc.format import Type as FormatType
+
+# ListCreativeFormatsRequest.type filter requires internal import:
+from adcp.types.generated_poc.list_creative_formats_request import Type as FilterType
+```
+
+**Impact**: Users working with Format objects or filtering formats cannot use stable API types.
+
+**Resolution (PR #222)**:
+- Created `/schemas/v1/enums/format-category.json` (7 values: audio, video, display, native, dooh, rich_media, universal)
+- `format.json` now references `FormatCategory` enum
+- `list-creative-formats-request.json` references full `FormatCategory` (no subsets)
+- `AssetContentType` remains for asset content types
+- Clear separation: content types vs. format categories
+
+## Recommended Solutions
+
+**Note**: PR #222 implemented Option A (Unique Naming) for enum collisions. Package collision remains.
+
+### Option A: Unique Naming (Quick Fix)
+
+Rename types in schemas to be self-descriptive:
+
+#### 1. Package Types
+```json
+// package.json
+"PackageStatus": { ... }  // Rename class from Package
+
+// create-media-buy-response.json
+"PackageReference": {     // Rename class from Package
+  "properties": {
+    "package_id": { ... },
+    "buyer_ref": { ... }
+  }
+}
+```
+
+**Rationale**: "PackageStatus" accurately describes the full state object. "PackageReference" clearly indicates a lightweight identifier.
+
+#### 2. AssetType Enums
+
+**Analysis**: These may actually be a versioning issue rather than distinct types. The schemas describe the same concept (asset content types) with different completeness levels.
+
+**Recommendation**: Consolidate into single canonical enum:
+
+```json
+// asset-types.json (new shared schema)
+{
+  "$id": "asset-types.json",
+  "AssetType": {
+    "enum": [
+      "image", "video", "audio", "text",
+      "html", "css", "javascript",
+      "vast", "daast",
+      "promoted_offerings",
+      "url", "markdown", "webhook"
+    ]
+  }
+}
+```
+
+Then reference via `$ref` from:
+- `asset-type.json`
+- `brand-manifest.json` (may allow subset for brand library)
+- `list-creative-formats-request.json` (may allow subset for filtering)
+- `format.json`
+
+**If subsets are intentional**: Use descriptive names:
+- `BrandAssetType`: Brand library assets (image, video, audio, text)
+- `CreativeFormatAssetType`: Format specifications (all 13 values)
+- `AssetTypeFilter`: Format filtering (7 queryable values)
+
+#### 3. Type Enums
+
+These represent genuinely different concepts:
+
+```json
+// asset-type.json
+"AssetContentType": {  // Rename from Type
+  "enum": ["image", "video", "audio", ...]
+}
+
+// format.json
+"FormatCategory": {    // Rename from Type
+  "enum": ["audio", "video", "display", "native", "dooh", "rich_media", "universal"]
+}
+
+// list-creative-formats-request.json
+"FormatCategoryFilter": {  // Rename from Type
+  "enum": ["audio", "video", "display", "dooh"]
+}
+```
+
+**Rationale**:
+- "AssetContentType" describes what the asset IS
+- "FormatCategory" describes the advertising channel/placement
+- "FormatCategoryFilter" describes the query subset
+
+### Option B: Schema Consolidation (Best Long-term)
+
+Refactor schemas to eliminate redundancy:
+
+1. **Shared definitions file**: Create `common-types.json` with canonical enums
+2. **Use $ref everywhere**: All schemas reference canonical definitions
+3. **Version enums explicitly**: If subsets are intentional, document why
+
+Example:
+```json
+// common-types.json
+{
+  "definitions": {
+    "AssetType": { "enum": [...] },
+    "FormatCategory": { "enum": [...] },
+    "PackageReference": { ... },
+    "PackageStatus": { ... }
+  }
+}
+
+// format.json
+{
+  "properties": {
+    "type": { "$ref": "common-types.json#/definitions/FormatCategory" }
+  }
+}
+```
+
+## Priority Recommendations
+
+### High Priority (Breaks stable API usage)
+
+1. **Package collision**: Rename to `PackageStatus` and `PackageReference`
+   - Impact: CreateMediaBuy response handling currently impossible with stable API
+   - Complexity: Low (rename in 2 schema files)
+
+2. **Format Type collision**: Rename to `FormatCategory`
+   - Impact: Working with Format.type field requires unstable imports
+   - Complexity: Low (rename in 2 schema files + update 1 reference)
+
+### Medium Priority (Workaround exists but fragile)
+
+3. **AssetType consolidation**: Merge into single canonical enum or namespace variants
+   - Impact: Format filtering and brand manifest usage require unstable imports
+   - Complexity: Medium (decide if differences are intentional, update 3+ schemas)
+
+## Migration Path
+
+If schema changes are accepted:
+
+1. **AdCP 2.9.0**: Publish schemas with new names
+2. **SDK transitional version**: Export both old and new names with deprecation warnings
+3. **SDK breaking version**: Remove old names, complete migration
+
+Example SDK migration:
+```python
+# adcp 2.9.x - Transitional
+from adcp.types import (
+    Package,           # Deprecated: Use PackageStatus
+    PackageStatus,     # New name
+    PackageReference,  # New name
+)
+
+# adcp 3.0.0 - Clean
+from adcp.types import (
+    PackageStatus,
+    PackageReference,
+)
+```
+
+## Questions for AdCP Team
+
+1. **AssetType differences**: Are the different AssetType enums intentional (different valid subsets) or incomplete schema evolution?
+
+2. **Enum versioning strategy**: Should we version enums when adding values (AssetTypeV1, AssetTypeV2) or maintain single growing enum?
+

+
+4. **Common types file**: Would AdCP benefit from a `common-types.json` with shared definitions?
+

Subject: [PATCH 2/9] test: remove obsolete CreatedPackageReference tests
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Removed 5 test functions that tested CreatedPackageReference since this type
was removed in AdCP PR #223. The PR unified Package responses so that both
create_media_buy and update_media_buy now return full Package objects instead
of minimal references.

Removed tests:
- test_package_type_aliases_imports
- test_package_type_aliases_point_to_correct_modules
- test_package_type_aliases_have_correct_fields
- test_package_type_aliases_in_exports
- test_package_aliases_can_instantiate

All 290 tests now pass.

 temp docs
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Removed temporary documentation files (SCHEMA_COLLISION_PROPOSAL.md,
UPSTREAM_SCHEMA_RECOMMENDATIONS.md) that were used during analysis.

Enhanced CHANGELOG_ENTRY.md to include:
- Detailed description of upstream schema improvements (PR #222 + #223)
- Complete list of new types with all enum values
- Expanded migration guide with more examples
- Upstream recommendations identified during integration

The key findings (orphaned asset-type.json, enum organization suggestions,
discriminator standardization opportunities) are now captured in the changelog
for future reference.

 ## Type System Updates (AdCP PR #222 + #223)
 
+This release integrates upstream schema improvements that resolved all type naming collisions in the AdCP protocol, enabling cleaner SDK APIs and better type safety.
+
 ### New Types
 
-- `AssetContentType`: Consolidated enum for asset content types (replaces multiple `AssetType` variants)
-- `FormatCategory`: New enum for format categories (display, video, native, dooh, etc.)
+- `AssetContentType`: Consolidated enum for asset content types (13 values: image, video, audio, text, html, css, javascript, vast, daast, promoted_offerings, url, markdown, webhook)
+- `FormatCategory`: New enum for format categories (7 values: audio, video, display, native, dooh, rich_media, universal)
 
 ### Breaking Changes
 
@@ -12,23 +14,40 @@
 
 ### Improvements
 
-- **Package collision resolved**: create_media_buy and update_media_buy now return identical Package structures
-- **Enum collision resolved**: Clear semantic names for asset content types vs. format categories
-- **Backward compatibility**: `AssetType` maintained as deprecated alias to `AssetContentType` (will be removed in 3.0.0)
+- **Package collision resolved**: `create_media_buy` and `update_media_buy` now return identical Package structures with all fields (budget, status, creative_assignments, etc.)
+- **Enum collisions resolved**: Clear semantic separation between `AssetContentType` (what an asset contains) and `FormatCategory` (how a format renders)
+- **No more qualified imports**: All types now cleanly exported from stable API - no need for `_PackageFromPackage` or similar workarounds
+- **Backward compatibility**: SDK maintains `AssetType` as deprecated alias during 2.x releases (will be removed in 3.0.0)
 
 ### Migration Guide
 
 ```python
-# Before
+# Before (using internal generated types)
 from adcp.types.generated_poc.brand_manifest import AssetType
 from adcp.types.generated_poc.format import Type
 
-# After
+# After (using stable public API)
 from adcp import AssetContentType, FormatCategory
 
-# Package responses now consistent
+# Package responses now consistent across create and update
 response = await client.create_media_buy(...)
 for pkg in response.packages:
-    # Full Package object with all fields (budget, status, etc.)
-    print(f"Package {pkg.package_id}: budget={pkg.budget}, status={pkg.status}")
+    # Full Package object with all fields available immediately
+    print(f"Package {pkg.package_id}:")
+    print(f"  Budget: {pkg.budget}")
+    print(f"  Status: {pkg.status}")
+    print(f"  Product: {pkg.product_id}")
+    print(f"  Pricing: {pkg.pricing_option_id}")
 ```
+
+### Upstream Recommendations Submitted
+
+Based on this integration work, we've identified and shared with the AdCP team:
+
+1. **Orphaned schema file**: `asset-type.json` is no longer referenced after PR #222 and should be removed
+2. **Enum organization**: Consider consolidating all reusable enums into `/schemas/v1/enums/` directory
+3. **Discriminator standardization**: Multiple patterns used (`type`, `output_format`, `delivery_type`, etc.) - could standardize on `type`
+4. **Schema-level validation**: Add JSON Schema 2019-09 `discriminator` keyword for better tooling support
+5. **Enum versioning policy**: Document whether new enum values are minor vs. major version changes
+
+Overall, the AdCP schemas are in excellent shape - these are minor polish suggestions.

-# AdCP Schema Naming Collision Fix Proposal
-
-**Date**: 2025-11-19 (Updated: 2025-11-20)
-**Submitted by**: Python SDK Maintainers
-**Status**: ✅✅✅ **ALL RESOLVED!** (PR #222 + PR #223)
-
-## Update: ALL Collisions Resolved! 🎉
-
-**PR #222** ("Consolidate enum types to eliminate naming collisions") - **MERGED**
-- ✅ **AssetType** → Now `AssetContentType` (13 values, consolidated from 4 variants)
-- ✅ **Type enums** → Now `AssetContentType` + `FormatCategory` (separated semantic types)
-
-**PR #223** ("Make create_media_buy and update_media_buy responses consistent") - **OPEN**
-- ✅ **Package** → Unified to always return full Package objects (no more minimal reference variant)
-
-## Executive Summary
-
-~~The current AdCP schemas contain type name collisions that prevent SDK code generators from creating clean, type-safe APIs. We propose renaming 3 types in the schemas to eliminate ambiguity and enable better downstream tooling.~~
-
-**UPDATE**: PR #222 resolved enum collisions. One remaining collision: the `Package` type used for both full state objects and lightweight response references.
-
-## Problem
-
-Multiple schema files define types with identical names but different semantics. Code generators cannot distinguish between them, forcing SDKs to expose internal workarounds or incomplete APIs.
-
-## ✅ RESOLVED: Package Collision (PR #223)
-
-### Better Solution Than Proposed!
-
-**Original Problem:**
-- `package.json` defined full `Package` (12 fields: full state)
-- `create-media-buy-response.json` defined minimal `Package` (2 fields: just IDs)
-- Code generators couldn't distinguish between them
-
-**Our Proposal Was:**
-Split into `PackageStatus` + `PackageReference`
-
-**What PR #223 Does (Better!):**
-Unifies responses to **always return full Package objects**
-
-**Changes:**
-```json
-// create-media-buy-response.json - NOW returns full Package
-{
-  "packages": [{
-    "package_id": "pkg_001",
-    "buyer_ref": "package_ref",
-    "product_id": "ctv_premium",    // NEW
-    "budget": 50000,                // NEW
-    "status": "active",             // NEW
-    "pacing": "even",               // NEW
-    "pricing_option_id": "cpm-fixed", // NEW
-    "creative_assignments": [],     // NEW
-    "format_ids_to_provide": []     // NEW
-  }]
-}
-
-// update-media-buy-response.json - Already returned full Package (no change)
-```
-
-**Benefits:**
-- ✅ **No collision**: Only one Package type exists now
-- ✅ **Consistency**: Create and update return identical structures
-- ✅ **Better UX**: Buyers see complete state without follow-up calls
-- ✅ **Backward compatible**: Additive change only (minor bump)
-- ✅ **Matches industry patterns**: Google Ad Manager, The Trade Desk do the same
-
-**Result**: Type generators produce clean, single `Package` type with no collisions or workarounds needed.
-
-### ✅ RESOLVED: Type Enums (PR #222)
-
-**What changed:**
-- Created `/schemas/v1/enums/asset-content-type.json` (13 values)
-- Created `/schemas/v1/enums/format-category.json` (7 values)
-- All schemas now reference these via `$ref`
-- Removed orphaned `asset-type.json`
-
-**Result**: Type generators now produce `AssetContentType` and `FormatCategory` with no collisions.
-
-### ✅ RESOLVED: AssetType Consolidation (PR #222)
-
-**What changed:**
-- Single canonical `AssetContentType` enum with 13 values
-- All schemas (`format.json`, `brand-manifest.json`, `list-creative-formats-request.json`) reference it
-- Filter APIs accept full enum (no artificial subsets)
-- Documentation notes typical usage where needed
-
-**Result**: No more AssetType variants or collisions.
-
-## Next Steps for Python SDK
-
-### When PR #223 Merges
-
-Once PR #223 is merged (currently open), the Python SDK can:
-
-#### 1. Sync Schemas
-```bash
-python3 scripts/sync_schemas.py
-```
-
-This pulls both PR #222 (merged) and PR #223 (pending) changes.
-
-#### 2. Regenerate Types
-```bash
-uv run python scripts/generate_types.py
-```
-
-This will generate:
-- `AssetContentType` enum (no more AssetType collisions)
-- `FormatCategory` enum (no more Type collisions)
-- Single `Package` class (no more Package collisions!)
-- No more `_PackageFromPackage` or `_PackageFromCreateMediaBuyResponse` workarounds
-
-#### 3. Update Stable API Exports
-Edit `src/adcp/types/stable.py`:
-```python
-# Import new enum names from PR #222
-from adcp.types._generated import (
-    AssetContentType,  # New canonical enum
-    FormatCategory,    # New semantic type
-    Package,           # Now clean! No collision workaround needed
-    # ... rest
-)
-
-# Remove old collision workaround:
-# from adcp.types._generated import _PackageFromPackage as Package  # DELETE THIS
-```
-
-#### 4. Add Deprecation Aliases (backward compatibility)
-```python
-# Deprecated aliases - remove in 3.0.0
-AssetType = AssetContentType
-# Note: Don't alias Type - it was ambiguous (asset types vs format categories)
-
-__all__ = [
-    "AssetContentType",
-    "FormatCategory",
-    "Package",
-    "AssetType",  # Deprecated, will be removed in 3.0.0
-]
-```
-
-#### 5. Remove Internal Import Workarounds
-Search and remove any uses of:
-- `from adcp.types.generated_poc.* import AssetType`
-- `from adcp.types.generated_poc.* import Type`
-- `from adcp.types._generated import _PackageFromCreateMediaBuyResponse`
-
-All should now use stable imports.
-
-## Benefits
-
-1. **Type Safety**: SDKs can generate clean, unambiguous types
-2. **Developer Experience**: Autocomplete works correctly, no internal imports needed
-3. **Maintainability**: Fewer workarounds in SDK codebases
-4. **Future-Proof**: Prevents accumulation of more collisions
-
-## Migration Impact (Python SDK)
-
-### Changes from PR #222
-- ✅ `AssetType` → `AssetContentType` (consolidated enum)
-- ✅ `Type` → `AssetContentType` + `FormatCategory` (separated enums)
-
-SDK will provide backward-compatible aliases during 2.x releases:
-```python
-AssetType = AssetContentType  # Deprecated alias
-```
-
-### All Breaking Changes Resolved!
-- ✅ `AssetType` → `AssetContentType` (PR #222, merged)
-- ✅ `Type` → `AssetContentType` + `FormatCategory` (PR #222, merged)
-- ✅ `Package` → Unified full Package type (PR #223, open)
-
-## No Remaining Questions!
-
-All collisions have been addressed by the AdCP team. The solutions chosen (especially PR #223's response unification) are superior to our original proposals.
-
-## Acknowledgments
-
-Huge thanks to the AdCP team for:
-- **PR #222**: Enum consolidation that follows best practices for type safety
-- **PR #223**: Response unification that's even better than our proposed type split - improves consistency AND eliminates collisions!
-
-These changes will significantly improve SDK ergonomics and make AdCP one of the most SDK-friendly ad tech protocols.
-
-## SDK Workarounds (Current State)
-
-```python
-# Python SDK currently must do this:
-from adcp.types._generated import (
-    _PackageFromPackage as Package,  # Qualified import
-    _PackageFromCreateMediaBuyResponse,  # Not exported
-)
-
-from adcp.types.generated_poc.format import Type as FormatType
-from adcp.types.generated_poc.asset_type import Type as AssetContentType
-
-# This is fragile and breaks on schema regeneration
-```

-**Status Update (2025-11-20)**: 🎉🎉🎉 **ALL RESOLVED!**
-- PR #222 (merged): Enum collisions fixed
-- PR #223 (open): Package collision fixed via response unification
-
-## Problem Statement
-
-The AdCP schemas contain type name collisions that create challenges for downstream SDK implementations. When multiple schema files define enums or classes with identical names but different semantics, code generators cannot automatically distinguish between them, forcing SDKs to either:
-
-1. Use internal "qualified imports" with workarounds (brittle, non-intuitive)
-2. Export only one variant through the stable API (breaks use cases needing the other variant)
-3. Require users to import from unstable internal paths (defeats type safety goals)
-
-This document identifies the specific collisions and recommends upstream schema changes.
-
-## Identified Collisions
-
-### Summary Status
-
-| Collision | Status | Resolution |
-|-----------|--------|------------|
-| AssetType enum | ✅ Resolved | PR #222 (merged): Consolidated to `AssetContentType` |
-| Type enum | ✅ Resolved | PR #222 (merged): Split into `AssetContentType` + `FormatCategory` |
-| Package class | ✅ Resolved | PR #223 (open): Unified responses to return full Package |
-
-### 1. Package Type Collision (✅ RESOLVED via PR #223)
-
-**Issue**: Two different `Package` types serve distinct purposes:
-
-- **Request Package** (`package.json`): Full package definition with 12 fields including status, creative assignments, targeting overlay
-  - Used in: Media buy state tracking, package updates, get operations
-  - Fields: `package_id`, `buyer_ref`, `status`, `budget`, `bid_price`, `impressions`, `product_id`, `pricing_option_id`, `creative_assignments`, `format_ids_to_provide`, `pacing`, `targeting_overlay`
-
-- **Response Package** (`create-media-buy-response.json`): Minimal package reference with 2 fields
-  - Used in: CreateMediaBuy success responses
-  - Fields: `package_id`, `buyer_ref`
-
-**Current Workaround**:
-```python
-# stable.py exports the full request Package
-from adcp.types._generated import _PackageFromPackage as Package
-
-# Response Package is not exported, requiring:
-from adcp.types.generated_poc.create_media_buy_response import Package
-```
-
-**Impact**: Users building CreateMediaBuy response handlers cannot use stable API types.
-
-**Resolution (PR #223 - Better than our proposal!):**
-
-Instead of splitting into `PackageStatus` + `PackageReference` as we proposed, PR #223 **unifies responses** to always return full Package objects:
-
-```json
-// create-media-buy-response.json - NOW returns full Package
-{
-  "packages": [{
-    "package_id": "pkg_001",
-    "buyer_ref": "package_ref",
-    "product_id": "ctv_premium",
-    "budget": 50000,
-    "status": "active",
-    "pacing": "even",
-    "pricing_option_id": "cpm-fixed",
-    "creative_assignments": [],
-    "format_ids_to_provide": []
-  }]
-}
-```
-
-**Benefits of this approach:**
-- ✅ Eliminates collision (only one Package type)
-- ✅ Improves API consistency (create and update return same structure)
-- ✅ Better developer experience (full state without follow-up calls)
-- ✅ Backward compatible (additive change only)
-
-### 2. AssetType Enum Collision (✅ RESOLVED in PR #222)
-
-**Issue**: Three different `AssetType` enums with overlapping but distinct value sets:
-
-- **asset-type.json** (11 values): `image`, `video`, `audio`, `text`, `html`, `css`, `javascript`, `vast`, `daast`, `promoted_offerings`, `url`
-  - Context: Asset specifications in format definitions
-
-- **list-creative-formats-request.json** (7 values): `image`, `video`, `audio`, `text`, `html`, `javascript`, `url`
-  - Context: Filtering formats by asset requirements
-  - Missing: `css`, `vast`, `daast`, `promoted_offerings`
-
-- **brand-manifest.json** (4 values): `image`, `video`, `audio`, `text`
-  - Context: Brand asset library items
-  - Missing: All markup/code types, structured ad formats
-
-**Current Workaround**:
-```python
-# stable.py exports asset-type.json's version (alphabetically first)
-from adcp.types.stable import AssetType
-
-# Other variants require internal imports:
-from adcp.types.generated_poc.list_creative_formats_request import AssetType
-from adcp.types.generated_poc.brand_manifest import AssetType
-```
-
-**Impact**: Users calling `list_creative_formats` with asset_types filter cannot use stable API enums.
-
-**Resolution (PR #222)**:
-- Created `/schemas/v1/enums/asset-content-type.json` with 13 canonical values
-- All schemas now reference this via `$ref`
-- Single `AssetContentType` enum generated by all SDKs
-- No more collisions or workarounds needed
-
-### 3. Type Enum Collision (✅ RESOLVED in PR #222)
-
-**Issue**: Two different `Type` enums serving different categorization purposes:
-
-- **asset-type.json** (11 values): Asset MIME/content types
-  - Values: `image`, `video`, `audio`, `text`, `html`, `css`, `javascript`, `vast`, `daast`, `promoted_offerings`, `url`
-  - Context: What kind of content an asset contains
-
-- **format.json** (7 values): Creative format categories
-  - Values: `audio`, `video`, `display`, `native`, `dooh`, `rich_media`, `universal`
-  - Context: Advertising channel/placement type
-
-- **list-creative-formats-request.json** (4 values): Format filtering categories
-  - Values: `audio`, `video`, `display`, `dooh`
-  - Context: Filter parameter for format listings
-  - Missing: `native`, `rich_media`, `universal`
-
-**Current Workaround**:
-```python
-# stable.py exports asset-type.json's Type (alphabetically first)
-from adcp.types.stable import Type  # Asset type, not format type!
-
-# Format.type enum requires internal import:
-from adcp.types.generated_poc.format import Type as FormatType
-
-# ListCreativeFormatsRequest.type filter requires internal import:
-from adcp.types.generated_poc.list_creative_formats_request import Type as FilterType
-```
-
-**Impact**: Users working with Format objects or filtering formats cannot use stable API types.
-
-**Resolution (PR #222)**:
-- Created `/schemas/v1/enums/format-category.json` (7 values: audio, video, display, native, dooh, rich_media, universal)
-- `format.json` now references `FormatCategory` enum
-- `list-creative-formats-request.json` references full `FormatCategory` (no subsets)
-- `AssetContentType` remains for asset content types
-- Clear separation: content types vs. format categories
-
-## Recommended Solutions
-
-**Note**: PR #222 implemented Option A (Unique Naming) for enum collisions. Package collision remains.
-
-### Option A: Unique Naming (Quick Fix)
-
-Rename types in schemas to be self-descriptive:
-
-#### 1. Package Types
-```json
-// package.json
-"PackageStatus": { ... }  // Rename class from Package
-
-// create-media-buy-response.json
-"PackageReference": {     // Rename class from Package
-  "properties": {
-    "package_id": { ... },
-    "buyer_ref": { ... }
-  }
-}
-```
-
-**Rationale**: "PackageStatus" accurately describes the full state object. "PackageReference" clearly indicates a lightweight identifier.
-
-#### 2. AssetType Enums
-
-**Analysis**: These may actually be a versioning issue rather than distinct types. The schemas describe the same concept (asset content types) with different completeness levels.
-
-**Recommendation**: Consolidate into single canonical enum:
-
-```json
-// asset-types.json (new shared schema)
-{
-  "$id": "asset-types.json",
-  "AssetType": {
-    "enum": [
-      "image", "video", "audio", "text",
-      "html", "css", "javascript",
-      "vast", "daast",
-      "promoted_offerings",
-      "url", "markdown", "webhook"
-    ]
-  }
-}
-```
-
-Then reference via `$ref` from:
-- `asset-type.json`
-- `brand-manifest.json` (may allow subset for brand library)
-- `list-creative-formats-request.json` (may allow subset for filtering)
-- `format.json`
-
-**If subsets are intentional**: Use descriptive names:
-- `BrandAssetType`: Brand library assets (image, video, audio, text)
-- `CreativeFormatAssetType`: Format specifications (all 13 values)
-- `AssetTypeFilter`: Format filtering (7 queryable values)
-
-#### 3. Type Enums
-
-These represent genuinely different concepts:
-
-```json
-// asset-type.json
-"AssetContentType": {  // Rename from Type
-  "enum": ["image", "video", "audio", ...]
-}
-
-// format.json
-"FormatCategory": {    // Rename from Type
-  "enum": ["audio", "video", "display", "native", "dooh", "rich_media", "universal"]
-}
-
-// list-creative-formats-request.json
-"FormatCategoryFilter": {  // Rename from Type
-  "enum": ["audio", "video", "display", "dooh"]
-}
-```
-
-**Rationale**:
-- "AssetContentType" describes what the asset IS
-- "FormatCategory" describes the advertising channel/placement
-- "FormatCategoryFilter" describes the query subset
-
-### Option B: Schema Consolidation (Best Long-term)
-
-Refactor schemas to eliminate redundancy:
-
-1. **Shared definitions file**: Create `common-types.json` with canonical enums
-2. **Use $ref everywhere**: All schemas reference canonical definitions
-3. **Version enums explicitly**: If subsets are intentional, document why
-
-Example:
-```json
-// common-types.json
-{
-  "definitions": {
-    "AssetType": { "enum": [...] },
-    "FormatCategory": { "enum": [...] },
-    "PackageReference": { ... },
-    "PackageStatus": { ... }
-  }
-}
-
-// format.json
-{
-  "properties": {
-    "type": { "$ref": "common-types.json#/definitions/FormatCategory" }
-  }
-}
-```
-
-## Priority Recommendations
-
-### High Priority (Breaks stable API usage)
-
-1. **Package collision**: Rename to `PackageStatus` and `PackageReference`
-   - Impact: CreateMediaBuy response handling currently impossible with stable API
-   - Complexity: Low (rename in 2 schema files)
-
-2. **Format Type collision**: Rename to `FormatCategory`
-   - Impact: Working with Format.type field requires unstable imports
-   - Complexity: Low (rename in 2 schema files + update 1 reference)
-
-### Medium Priority (Workaround exists but fragile)
-
-3. **AssetType consolidation**: Merge into single canonical enum or namespace variants
-   - Impact: Format filtering and brand manifest usage require unstable imports
-   - Complexity: Medium (decide if differences are intentional, update 3+ schemas)
-
-## Migration Path
-
-If schema changes are accepted:
-
-1. **AdCP 2.9.0**: Publish schemas with new names
-2. **SDK transitional version**: Export both old and new names with deprecation warnings
-3. **SDK breaking version**: Remove old names, complete migration
-
-Example SDK migration:
-```python
-# adcp 2.9.x - Transitional
-from adcp.types import (
-    Package,           # Deprecated: Use PackageStatus
-    PackageStatus,     # New name
-    PackageReference,  # New name
-)
-
-# adcp 3.0.0 - Clean
-from adcp.types import (
-    PackageStatus,
-    PackageReference,
-)
-```
-
-## Questions for AdCP Team
-
-1. **AssetType differences**: Are the different AssetType enums intentional (different valid subsets) or incomplete schema evolution?
-
-2. **Enum versioning strategy**: Should we version enums when adding values (AssetTypeV1, AssetTypeV2) or maintain single growing enum?
-
-3. **Breaking change policy**: Can we coordinate schema renames in AdCP 2.9 or should we wait for 3.0?
-
-4. **Common types file**: Would AdCP benefit from a `common-types.json` with shared definitions?

Subject: [PATCH 4/9] fix: remove orphaned asset-type.json and update schemas
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Upstream PR #222 removed the orphaned asset-type.json schema file. Our local
cache had stale copies that were no longer referenced upstream.

Changes:
- Removed stale asset-type.json from schemas/cache/1.0.0/
- Removed asset_type.py generated file (no longer has upstream schema)
- Removed orphaned type exports: AssetTypeSchema, ContentLength, Dimensions,
  Duration, FileSize, Quality, Requirements
- Added deprecation alias: AssetType = AssetContentType
- Synced 6 updated schemas (deployment, destination, activate-signal, get-signals)

The sync discovered asset-type.json was 404 upstream - it was removed in PR #222
as part of the enum consolidation work.

Tests: 288/290 passing (2 failures in signals tests due to schema API changes
from destinations → deployments in upstream)

Subject: [PATCH 6/9] feat: automatically remove orphaned schemas during sync
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Added automatic cleanup of schema files that no longer exist upstream.
This prevents stale cached schemas from causing issues when upstream
removes or renames schema files.

Changes:
- Scan for JSON files in cache that aren't in the upstream schema list
- Remove orphaned files and their empty parent directories
- Report removed count in sync summary
- Updated script documentation to explain new feature

Example output:
  Cleaning up orphaned schemas:
    ✗ asset-type.json (removed - no longer in upstream)
    ✗ core/asset-type.json (removed - no longer in upstream)

This would have automatically caught the stale asset-type.json files
that were orphaned after PR #222.

Upstream schema updates changed the signals API from using 'destinations'
to 'deployments'. Updated test fixtures to match new API structure.

Changes:
- GetSignalsRequest.deliver_to.destinations → deployments
- ActivateSignalRequest.destinations → deployments

-## Type System Updates (AdCP PR #222 + #223)
-
-This release integrates upstream schema improvements that resolved all type naming collisions in the AdCP protocol, enabling cleaner SDK APIs and better type safety.
-
-### New Types
-
-- `AssetContentType`: Consolidated enum for asset content types (13 values: image, video, audio, text, html, css, javascript, vast, daast, promoted_offerings, url, markdown, webhook)
-- `FormatCategory`: New enum for format categories (7 values: audio, video, display, native, dooh, rich_media, universal)
-
-### Breaking Changes
-
-- **Removed `CreatedPackageReference`**: PR #223 unified responses - `create_media_buy` now returns full `Package` objects instead of minimal references
-- **Removed `AffectedPackage`**: Type removed from upstream schemas
-
-### Improvements
-
-- **Package collision resolved**: `create_media_buy` and `update_media_buy` now return identical Package structures with all fields (budget, status, creative_assignments, etc.)
-- **Enum collisions resolved**: Clear semantic separation between `AssetContentType` (what an asset contains) and `FormatCategory` (how a format renders)
-- **No more qualified imports**: All types now cleanly exported from stable API - no need for `_PackageFromPackage` or similar workarounds
-- **Backward compatibility**: SDK maintains `AssetType` as deprecated alias during 2.x releases (will be removed in 3.0.0)
-
-### Migration Guide
-
-```python
-# Before (using internal generated types)
-from adcp.types.generated_poc.brand_manifest import AssetType
-from adcp.types.generated_poc.format import Type
-
-# After (using stable public API)
-from adcp import AssetContentType, FormatCategory
-
-# Package responses now consistent across create and update
-response = await client.create_media_buy(...)
-for pkg in response.packages:
-    # Full Package object with all fields available immediately
-    print(f"Package {pkg.package_id}:")
-    print(f"  Budget: {pkg.budget}")
-    print(f"  Status: {pkg.status}")
-    print(f"  Product: {pkg.product_id}")
-    print(f"  Pricing: {pkg.pricing_option_id}")
-```
-
-### Upstream Schema Quality
-
-The AdCP team removed orphaned schemas as part of PR #222 - `asset-type.json` was properly cleaned up from the repository. This SDK release reflects that cleanup.
-
-Additional opportunities for future schema improvements:
-
-1. **Enum organization**: Consider consolidating all reusable enums into `/schemas/v1/enums/` directory
-2. **Discriminator standardization**: Multiple patterns used (`type`, `output_format`, `delivery_type`, etc.) - could standardize on `type`
-3. **Schema-level validation**: Add JSON Schema 2019-09 `discriminator` keyword for better tooling support
-4. **Enum versioning policy**: Document whether new enum values are minor vs. major version changes
-
-Overall, the AdCP schemas are in excellent shape - these are minor polish suggestions.
