Code Review for PR #1596: Catches PortValue unknown decoding errors

Summary

This PR adds error handling for unknown decoding errors when parsing PortValue data in the Stitch AI layer derivation logic.

✅ Strengths

• Good defensive programming: Adding a catch-all case for DecodingError improves robustness
• Proper error propagation: The error is correctly wrapped in the existing error type hierarchy
• Consistent error handling pattern: Follows the existing pattern of catching specific error types

⚠️ Issues & Suggestions

1. Typo in log message

In deriveLayer.swift:503, there is a typo: "unkonwn" should be "unknown"

log("SyntaxViewName.deriveLayerData unkonwn decoding error: \(error)")

2. Missing enum case in description

The new .unknown case added to StitchAIParsingError (line 122) needs a corresponding case in the CustomStringConvertible extension (lines 130-151). Add this after line 148:

case .unknown(let string):
    return "Unknown decoding error: \(string)"

3. Consider more specific error information

Instead of using error.localizedDescription, consider extracting more specific information from the DecodingError to aid debugging:

• typeMismatch: Include the expected type and context
• valueNotFound: Include the missing value type
• keyNotFound: Include the missing key name
• dataCorrupted: Include corruption context

This would provide more actionable error messages for debugging.

🔒 Security Considerations

No security concerns identified. The error handling does not expose sensitive information.

🚀 Performance Considerations

No performance impact - this is purely error handling code that only executes in failure cases.

🧪 Test Coverage

Consider adding unit tests for the new error case to ensure:

1. DecodingErrors are properly caught and wrapped
2. The error message is correctly formatted
3. Silent errors are properly collected

Recommendation

Approve with minor changes - Fix the typo and add the missing description case. The more detailed error extraction is optional but would improve debugging capabilities.
