Subject: [PATCH 4/6] Add CLI subcommands and comprehensive integration tests
 for issue #199

Implements proper CLI subcommand architecture and integration tests that
demonstrate the three new CloudKit operations (lookupZones, fetchRecordChanges,
uploadAssets) working together in realistic workflows.

New CLI Subcommands:
- upload-asset: Upload binary assets to CloudKit
- lookup-zones: Look up specific zones by name
- fetch-changes: Fetch record changes with incremental sync
- test-integration: Run comprehensive 8-phase integration tests

Integration Test Suite (8 Phases):
1. Zone verification with lookupZones
2. Asset upload with uploadAssets (programmatic PNG generation)
3. Record creation with uploaded assets
4. Initial sync with fetchRecordChanges
5. Record modifications
6. Incremental sync demonstrating sync token usage
7. Final zone verification
8. Automatic cleanup

Infrastructure:
- CloudKitCommand protocol for shared functionality across subcommands
- IntegrationTestRunner orchestrates all test phases
- IntegrationTestData generates test PNG images programmatically
- IntegrationTestError provides typed error handling
- schema.ckdb defines MistKitIntegrationTest record type

Architecture Changes:
- Converted MistDemo from flag-based to subcommand architecture
- Added Commands/ directory for subcommand implementations
- Added Integration/ directory for test infrastructure
- CloudKitCommand protocol resolves API tokens from env or options

Documentation:
- README-INTEGRATION-TESTS.md with complete usage guide
- Schema deployment instructions
- Troubleshooting guide
- Example outputs for all commands

All subcommands support:
- API token from --api-token or CLOUDKIT_API_TOKEN env var
- Container identifier configuration
- Development/production environment selection

Test integration features:
- Configurable record count (--record-count)
- Configurable asset size (--asset-size)
- Verbose mode for detailed output (--verbose)
- Skip cleanup flag for manual inspection (--skip-cleanup)

+# MistDemo Integration Tests - Issue #199
+
+This document describes the comprehensive integration test suite for the three new CloudKit operations added in issue #199: `lookupZones`, `fetchRecordChanges`, and `uploadAssets`.
+
+## Overview
+
+MistDemo has been enhanced with a proper CLI subcommand architecture and comprehensive integration tests that demonstrate all three new operations working together in realistic workflows.
+
+## Available Commands
+
+```bash
+# Show all available subcommands
+mistdemo --help
+
+# Get help for a specific command
+mistdemo test-integration --help
+mistdemo upload-asset --help
+mistdemo lookup-zones --help
+mistdemo fetch-changes --help
+```
+
+## Quick Start
+
+### 1. Deploy CloudKit Schema (One-Time Setup)
+
+Before running integration tests, deploy the schema to CloudKit:
+
+```bash
+# Save your CloudKit management token
+xcrun cktool save-token
+
+# Import the schema to development environment
+xcrun cktool import-schema \
+  --team-id YOUR_TEAM_ID \
+  --container-id iCloud.com.brightdigit.MistDemo \
+  --environment development \
+  --file schema.ckdb
+```
+
+### 2. Run Integration Tests
+
+```bash
+# Basic integration test
+swift run mistdemo test-integration --api-token YOUR_TOKEN
+
+# Verbose mode with more records
+swift run mistdemo test-integration \
+  --api-token YOUR_TOKEN \
+  --record-count 20 \
+  --verbose
+
+# Skip cleanup to inspect records in CloudKit Console
+swift run mistdemo test-integration \
+  --api-token YOUR_TOKEN \
+  --skip-cleanup
+```
+
+## Individual Operation Commands
+
+### Upload Asset
+
+Upload a binary file to CloudKit:
+
+```bash
+# Upload a file
+swift run mistdemo upload-asset photo.jpg --api-token YOUR_TOKEN
+
+# Upload and create a record
+swift run mistdemo upload-asset document.pdf \
+  --create-record Document \
+  --api-token YOUR_TOKEN
+```
+
+**Features:**
+- Validates file existence
+- Displays upload progress
+- Returns asset tokens
+- Optionally creates a record with the asset
+
+### Lookup Zones
+
+Fetch detailed information about specific zones:
+
+```bash
+# Lookup default zone
+swift run mistdemo lookup-zones "_defaultZone" --api-token YOUR_TOKEN
+
+# Lookup multiple zones
+swift run mistdemo lookup-zones "Photos,Documents,Articles" --api-token YOUR_TOKEN
+```
+
+**Features:**
+- Supports comma-separated zone names
+- Displays zone capabilities
+- Shows owner information
+
+### Fetch Changes
+
+Fetch record changes with incremental sync:
+
+```bash
+# Initial fetch
+swift run mistdemo fetch-changes --api-token YOUR_TOKEN
+
+# Incremental fetch with sync token
+swift run mistdemo fetch-changes \
+  --sync-token "abc123..." \
+  --api-token YOUR_TOKEN
+
+# Fetch all with automatic pagination
+swift run mistdemo fetch-changes --fetch-all --api-token YOUR_TOKEN
+
+# Custom zone and limit
+swift run mistdemo fetch-changes \
+  --zone MyZone \
+  --limit 50 \
+  --api-token YOUR_TOKEN
+```
+
+**Features:**
+- Supports sync tokens for incremental sync
+- Automatic pagination with `--fetch-all`
+- Displays sync tokens for next fetch
+- Shows `moreComing` flag
+
+## Integration Test Suite
+
+The `test-integration` command runs a comprehensive 8-phase workflow:
+
+### Phase 1: Zone Verification
+- Uses `lookupZones(zoneIDs: [.defaultZone])`
+- Verifies zone exists before testing
+- Displays zone capabilities
+
+### Phase 2: Asset Upload
+- Generates test PNG image programmatically
+- Uploads using `uploadAssets(data:)`
+- Configurable size via `--asset-size` (default: 100 KB)
+
+### Phase 3: Create Records with Assets
+- Creates N test records (default: 10)
+- Each record includes: title, index, image asset, timestamp
+- Uses record type: `MistKitIntegrationTest`
+
+### Phase 4: Initial Sync
+- Fetches all records with `fetchRecordChanges()`
+- Saves sync token
+- Verifies test records are included
+
+### Phase 5: Modify Records
+- Updates first 3 records
+- Adds "modified" boolean field
+- Changes title field
+
+### Phase 6: Incremental Sync
+- Uses saved sync token
+- Fetches only modified records
+- Demonstrates incremental sync efficiency
+
+### Phase 7: Final Zone Verification
+- Re-verifies zone state
+- Ensures operations didn't corrupt zone
+
+### Phase 8: Cleanup
+- Deletes all test records
+- Skip with `--skip-cleanup` flag
+- Partial cleanup on errors
+
+## Command Options
+
+### Common Options
+
+All subcommands support:
+
+```bash
+--api-token <token>          # CloudKit API token (or set CLOUDKIT_API_TOKEN env var)
+--container-identifier <id>  # Container ID (default: iCloud.com.brightdigit.MistDemo)
+--environment <env>          # development or production (default: development)
+```
+
+### Test Integration Options
+
+```bash
+--record-count <N>    # Number of test records (default: 10)
+--asset-size <KB>     # Asset size in KB (default: 100)
+--skip-cleanup        # Leave test records in CloudKit
+--verbose             # Show detailed progress
+```
+
+## CloudKit Schema
+
+The integration tests use a custom record type defined in `schema.ckdb`:
+
+```
+RECORD TYPE MistKitIntegrationTest (
+    "title"      STRING QUERYABLE SORTABLE SEARCHABLE,
+    "index"      INT64 QUERYABLE SORTABLE,
+    "image"      ASSET,
+    "createdAt"  TIMESTAMP QUERYABLE SORTABLE,
+    "modified"   INT64 QUERYABLE,
+
+    GRANT READ, CREATE, WRITE TO "_creator",
+    GRANT READ, CREATE, WRITE TO "_icloud",
+    GRANT READ TO "_world"
+);
+```
+
+**Field Descriptions:**
+- `title` - Test record title
+- `index` - Sequential number for ordering
+- `image` - Uploaded test asset
+- `createdAt` - Record creation timestamp
+- `modified` - Boolean flag (0/1) set during updates
+
+## Example Output

+
+## Troubleshooting
+
+### Schema Not Found
+
+If you see errors about `MistKitIntegrationTest` not existing:
+
+1. Verify schema was deployed: Check CloudKit Console → Schema
+2. Re-import schema using `cktool import-schema`
+3. Ensure you're using the correct environment (`--environment development`)
+
+### Authentication Failed
+
+If you see authentication errors:
+
+1. Verify your API token: https://icloud.developer.apple.com/dashboard/
+2. Check token has permissions for the container
+3. Ensure token hasn't expired
+4. Try setting `CLOUDKIT_API_TOKEN` environment variable
+
+### No Records Found
+
+If integration tests report no records found:
+
+1. Records may not be immediately available after creation
+2. Try running the test again
+3. Use `--skip-cleanup` and check CloudKit Console
+4. Verify you're using the correct database (public vs private)

+```
+
+### CloudKitCommand Protocol
+
+All subcommands conform to the `CloudKitCommand` protocol:
+
+```swift
+protocol CloudKitCommand {
+    var containerIdentifier: String { get }
+    var apiToken: String { get }
+    var environment: String { get }
+}
+
+extension CloudKitCommand {
+    func resolvedApiToken() -> String
+    func cloudKitEnvironment() -> MistKit.Environment
+}
+```
+
+## Testing with Live CloudKit
+
+To test against your own CloudKit container:
+
+1. Create a container at https://icloud.developer.apple.com/
+2. Generate an API token
+3. Deploy the schema to your container
+4. Update the default container ID or use `--container-identifier`
+5. Run tests:
+
+```bash
+swift run mistdemo test-integration \
+  --container-identifier iCloud.com.yourcompany.YourApp \
+  --api-token YOUR_TOKEN \
+  --environment development
+```
+
+## Future Enhancements
+
+Documented in the plan:
+
+1. **Custom Zone Support** - Add `modifyZones` wrapper to test multi-zone scenarios
+2. **Pagination Testing** - Create 50+ records to trigger pagination
+3. **Error Scenario Testing** - Test invalid zones, corrupted tokens, oversized assets
+4. **Concurrent Operations** - Test parallel uploads and modifications
+5. **Performance Metrics** - Track timing for each phase
+6. **JSON Output** - Machine-readable results for CI/CD integration
+
+## Contributing
+
+When adding new CloudKit operations:
+
+1. Create a subcommand in `Commands/`
+2. Implement the `CloudKitCommand` protocol
+3. Add to the `MistDemo.configuration.subcommands` array
+4. Update integration tests if needed
+5. Document usage in this README

Subject: [PATCH 5/6] feat: implement private database support and web
 authentication for new CloudKit APIs
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Add private database support to integration tests with AdaptiveTokenManager
- Implement web authentication server with CloudKit.js integration
- Add web auth token options to CLI commands (--web-auth-token)
- Support CLOUDKIT_WEBAUTH_TOKEN environment variable
- Update integration test runner to handle both public/private databases
- Add comprehensive CloudKit.js authentication flow with multiple token extraction methods
- Create browser-based authentication interface with proper error handling
- Document testing status and next steps in TESTING_STATUS.md

New CLI options:
- test-integration --database [public|private] --web-auth-token TOKEN
- All commands now support web authentication for private database access

Authentication flow:
1. swift run mistdemo auth (starts web server)
2. Browser-based Apple ID sign-in with CloudKit.js
3. Automatic web auth token extraction and display
4. Use token with integration tests and individual operations

Ready to test lookupZones, fetchRecordChanges, and uploadAssets APIs
once web authentication token extraction is working correctly.

+# MistKit Branch 199 Testing Status
+
+## Current State
+
+We're on branch `199-cloudkit-api-coverage` testing three new CloudKit operations:
+- `lookupZones` - Look up specific zones by ID
+- `fetchRecordChanges` - Get record changes with sync tokens  
+- `uploadAssets` - Upload binary assets to CloudKit
+
+## What's Been Completed ✅
+
+### 1. Code Implementation
+- ✅ All three new API operations are implemented in MistKit
+- ✅ Integration test suite created in `Examples/MistDemo`
+- ✅ CLI commands created: `lookup-zones`, `fetch-changes`, `upload-asset`, `test-integration`
+- ✅ Modified integration tests to use private database with web authentication
+- ✅ Built successfully without compilation errors
+
+### 2. Authentication Infrastructure 
+- ✅ Updated integration tests to support both API token + web auth token
+- ✅ Created `AdaptiveTokenManager` setup for private database access
+- ✅ Added environment variable support for `CLOUDKIT_WEBAUTH_TOKEN`
+- ✅ Implemented web authentication server in `auth` command
+
+## Current Blocker ❌
+
+### Web Authentication Not Working
+The CloudKit.js web authentication flow is failing to extract web auth tokens:
+
+**Error**: `container.requestApplicationPermission is not a function`
+
+**Attempted Fixes**:
+- ✅ Updated to use `setUpAuth()` and `signInWithAppleID()` instead
+- ✅ Added multiple token extraction methods
+- ✅ Enhanced debugging and error handling
+- ❌ **Still not successfully capturing web auth tokens**
+
+## CloudKit Authentication Requirements
+
+| Database | Operation | Auth Method Required |
+|----------|-----------|---------------------|
+| Public | Read | API Token OR Server-to-Server |
+| Public | Write | API Token + Web Auth Token OR Server-to-Server |
+| Private | Any | API Token + Web Auth Token (user must sign in) |
+
+## Next Steps to Consider
+
+### Option A: Fix Web Authentication (Recommended)
+1. **Research CloudKit.js v2 API** - The current implementation may be using outdated methods
+2. **Check Apple's latest CloudKit Web Services docs** for correct authentication flow
+3. **Test with minimal CloudKit.js example** outside of our app
+4. **Consider using CloudKit Dashboard's token generator** as alternative
+
+### Option B: Use Server-to-Server Authentication  
+1. **Generate server-to-server certificate** for the container
+2. **Upload public key to CloudKit Dashboard**
+3. **Test with public database only** (server-to-server can't access private)
+4. **Modify integration tests** to use server-to-server keys
+
+### Option C: Manual Token Extraction
+1. **Use browser developer tools** to manually extract web auth token
+2. **Inspect CloudKit Dashboard network requests** for token format
+3. **Use captured token directly** in CLI commands for testing
+
+## Test Commands Ready to Use
+
+Once we have a working web auth token:
+
+```bash
+# Test integration suite
+swift run mistdemo test-integration \
+  --api-token dbc855f4034e6f4ff0c71bd4b59f251f0f21b4aff213a446f8c76ee70b670193 \
+  --web-auth-token YOUR_TOKEN \
+  --database private
+
+# Test individual operations
+swift run mistdemo lookup-zones --web-auth-token YOUR_TOKEN
+swift run mistdemo fetch-changes --web-auth-token YOUR_TOKEN  
+swift run mistdemo upload-asset file.jpg --web-auth-token YOUR_TOKEN
+```
+
+## Files Modified
+
+### Core Implementation
+- `Sources/MistKit/Service/CloudKitService+Operations.swift` - New API operations
+- `Sources/MistKit/Service/CloudKitService+WriteOperations.swift` - Asset upload
+
+### Test Infrastructure  
+- `Examples/MistDemo/Sources/MistDemo/Commands/TestIntegration.swift` - Updated for private DB
+- `Examples/MistDemo/Sources/MistDemo/Integration/IntegrationTestRunner.swift` - Web auth support
+- `Examples/MistDemo/Sources/MistDemo/MistDemo.swift` - Web authentication server
+
+### New Commands
+- `Examples/MistDemo/Sources/MistDemo/Commands/LookupZones.swift`
+- `Examples/MistDemo/Sources/MistDemo/Commands/FetchChanges.swift`
+- `Examples/MistDemo/Sources/MistDemo/Commands/UploadAsset.swift`
+
+## Container Configuration
+
+- **Container ID**: `iCloud.com.brightdigit.MistDemo`
+- **API Token**: `dbc855f4034e6f4ff0c71bd4b59f251f0f21b4aff213a446f8c76ee70b670193`
+- **Environment**: `development`
+- **Schema**: `schema.ckdb` (needs to be deployed)
+
+## Priority
+
+**HIGH**: Get web authentication working to test the new APIs with private database access, which is the most realistic use case for these operations.

Subject: [PATCH 6/6] feat: enhance CloudKit.js web auth token extraction and
 update testing status

MAJOR IMPROVEMENTS:
- Enhanced postMessage listener with origin verification (icloud.com, apple-cloudkit.com)
- Added network request interception (fetch/XHR) as fallback token capture method
- Extended timeout from 5s to 10s for token arrival
- Added browser debugging helpers (mistKitDebug.*)
- Simplified handleAuthentication() removing 160+ lines of non-working detection code

IMPLEMENTATION DETAILS:
Phase 1: Enhanced postMessage capture
  - Origin validation for security
  - Support for multiple token formats (plain string `158__54__...`, object properties)
  - Global token storage in window.cloudKitWebAuthToken

Phase 2: Network interception fallback
  - Intercepts fetch() and XMLHttpRequest
  - Captures tokens from CloudKit API responses
  - Logs all CloudKit requests for debugging

Phase 3: Simplified authentication flow
  - Removed localStorage, cookies, property access strategies (didn't work)
  - Clean token promise with 10s timeout
  - Manual extraction instructions on failure

Phase 5: Debugging helpers
  - mistKitDebug.container() - Get CloudKit container
  - mistKitDebug.token() - Get current token
  - mistKitDebug.setToken(tok) - Manually set token
  - mistKitDebug.sendToServer() - Send token to server
  - mistKitDebug.inspectContainer() - Inspect container for token

TESTING STATUS UPDATE:
- Web auth token successfully extracted manually (158__54__... format verified)
- Implementation complete and ready for testing
- Blocked on CloudKit container configuration (421 Misdirected Request)
- Need to verify container setup at icloud.developer.apple.com/dashboard

+# Support Swift Testing Framework Detection for WASM Builds
+
+## Problem Description
+
+When running WASM tests with `swift-build`, tests using the Swift Testing framework (`import Testing`) are not being discovered and executed, resulting in "0 tests" output:
+
+```
+Searching for Wasm test binaries...
+Found test binaries:
+.build/wasm32-unknown-wasip1/debug/MistKitPackageTests.xctest
+
+Running tests with WasmKit: .build/wasm32-unknown-wasip1/debug/MistKitPackageTests.xctest
+Test Suite 'All tests' started at 1970-01-01 00:03:45.952
+Test Suite 'debug.xctest' started at 1970-01-01 00:03:46.013
+Test Suite 'debug.xctest' passed at 1970-01-01 00:03:46.014
+     Executed 0 tests, with 0 failures (0 unexpected) in 0.0 (0.0) seconds
+```
+
+## Root Cause
+
+The action currently runs WASM test binaries without specifying the testing library:
+
+```bash
+wasmkit run MistKitPackageTests.xctest
+```
+
+However, Swift Testing tests on WASM require an explicit flag:
+
+```bash
+wasmkit run MistKitPackageTests.xctest -- --testing-library swift-testing
+```
+
+When this flag is provided, tests execute correctly:
+
+```
+◇ Test run started.
+↳ Testing Library Version: 6.2.3 (48a471ab313e858)
+↳ Target Platform: wasm32-unknown-wasip
+◇ Suite "Token Manager - Authentication Method" started.
+✔ Test "AuthenticationMethod computed properties" passed after 0.016 seconds.
+...
+Test run with 487 tests passed after 28.891 seconds.
+```
+
+## Background: WASM Testing Requirements
+
+Unlike native platforms where Swift Package Manager auto-detects the testing framework, WASM requires explicit specification:
+
+- **Swift Testing tests** (`@Test`, `@Suite`): Require `--testing-library swift-testing`
+- **XCTest tests** (`XCTestCase` subclasses): Run without flag or with `--testing-library xctest`
+- **Mixed tests**: Currently problematic on WASM (would require multiple test runs)
+
+Reference: [Swift Testing WASI Documentation](https://github.com/swiftlang/swift-testing/blob/main/Documentation/WASI.md)
+
+## Proposed Solution
+
+Add automatic testing framework detection with an optional override parameter.
+
+### New Action Parameters
+
+```yaml
+inputs:
+  wasm-testing-library:
+    description: 'Testing framework for WASM tests (auto, swift-testing, xctest, both)'
+    required: false
+    default: 'auto'
+
+  wasm-swift-test-flags:
+    description: 'Additional flags to pass to WASM test runner'
+    required: false
+```
+
+### Detection Algorithm
+
+When `wasm-testing-library: 'auto'` (default):
+
+1. **Scan test sources** for imports:
+   ```bash
+   # Check for Swift Testing
+   grep -r "import Testing" Tests/ --include="*.swift" -q
+   HAS_SWIFT_TESTING=$?
+
+   # Check for XCTest
+   grep -r "import XCTest" Tests/ --include="*.swift" -q
+   HAS_XCTEST=$?
+   ```
+
+2. **Determine testing library**:
+   - If only Swift Testing found → Use `--testing-library swift-testing`
+   - If only XCTest found → Use `--testing-library xctest` (or no flag)
+   - If both found → Use `both` mode (run twice)
+   - If neither found → Use `--testing-library swift-testing` (Swift 6+ default)
+
+3. **Execute tests accordingly**:
+   ```bash
+   case $TESTING_LIBRARY in
+     swift-testing)
+       wasmkit run $TEST_BINARY -- --testing-library swift-testing
+       ;;
+     xctest)
+       wasmkit run $TEST_BINARY -- --testing-library xctest
+       ;;
+     both)
+       echo "Running Swift Testing tests..."
+       wasmkit run $TEST_BINARY -- --testing-library swift-testing
+       echo "Running XCTest tests..."
+       wasmkit run $TEST_BINARY -- --testing-library xctest
+       ;;
+   esac
+   ```
+
+### Manual Override Examples
+
+For projects that know their testing framework:
+
+```yaml
+# Force Swift Testing
+- uses: brightdigit/swift-build@1.5.0-beta.2
+  with:
+    type: wasm
+    wasm-testing-library: swift-testing
+
+# Force XCTest
+- uses: brightdigit/swift-build@1.5.0-beta.2
+  with:
+    type: wasm
+    wasm-testing-library: xctest
+
+# Force both (run twice)
+- uses: brightdigit/swift-build@1.5.0-beta.2
+  with:
+    type: wasm
+    wasm-testing-library: both
+
+# Pass additional test flags
+- uses: brightdigit/swift-build@1.5.0-beta.2
+  with:
+    type: wasm
+    wasm-swift-test-flags: --filter "TestSuiteName"
+```
+
+## Alternative Approach: Package Manifest Detection
+
+Instead of scanning sources, parse `Package.swift` for test target dependencies:
+
+```swift
+.testTarget(
+  name: "MyTests",
+  dependencies: ["MyPackage", "Testing"]  // Swift Testing
+)
+
+.testTarget(
+  name: "MyTests",
+  dependencies: ["MyPackage", "XCTest"]   // XCTest
+)
+```
+
+This approach is more reliable but requires parsing Swift code or running SPM commands.
+
+## Benefits
+
+1. **Backward compatible**: Default `auto` mode works for existing projects
+2. **Zero configuration**: Automatically detects and uses correct framework
+3. **Future-proof**: Supports mixed testing scenarios
+4. **Performance**: Can skip tests with explicit `wasm-testing-library: none`
+5. **Flexibility**: Manual override for edge cases
+
+## Implementation Checklist
+
+- [ ] Add new input parameters to `action.yml`
+- [ ] Implement testing framework detection logic
+- [ ] Update WASM test execution script to pass appropriate flags
+- [ ] Add tests for auto-detection (Swift Testing, XCTest, mixed, none)
+- [ ] Update README with new parameters and examples
+- [ ] Add migration guide for existing users
+- [ ] Consider adding warning when mixed tests detected
+
+## Related Issues
+
+- #72: Swap Wasmtime for WasmKit (completed)
+- #30: Add WASM Support (foundation)
+- #68: WASM code coverage is not supported (separate concern)
+
+## Testing
+
+This issue was discovered while testing [MistKit](https://github.com/brightdigit/MistKit) which uses Swift Testing exclusively. The tests work correctly when run manually with:
+
+```bash
+swift build --swift-sdk swift-6.2.3-RELEASE_wasm --build-tests \
+  -Xcc -D_WASI_EMULATED_SIGNAL \
+  -Xcc -D_WASI_EMULATED_MMAN \
+  -Xlinker -lwasi-emulated-signal \
+  -Xlinker -lwasi-emulated-mman
+
+wasmkit run .build/wasm32-unknown-wasip1/debug/MistKitPackageTests.xctest -- --testing-library swift-testing
+```
+
+Result: All 487 tests pass successfully.
+
+## Additional Context
+
+- Swift Testing became the default testing framework in Swift 6.0
+- Many modern projects are migrating from XCTest to Swift Testing
+- WASM support is critical for cross-platform Swift development
+- This issue affects any project using Swift Testing with WASM builds
+
+## Questions for Maintainers
+
+1. Is source scanning an acceptable approach, or would you prefer Package.swift parsing?
+2. Should the default be `auto` or require explicit configuration?
+3. For mixed tests, should we run both or fail with an error message?
+4. Should we emit a GitHub Actions warning when mixed tests are detected?
