🧠 Logic: Implement more granular resource errors

[coderabbitai]

This issue tracks the implementation of more granular errors for resources, such as context_absent or context_not_found, as discussed in PR #564 (#564) and the related comment chain (#564 (comment)).

The need for more specific error types was highlighted to improve error handling and debugging. Implementing errors like context_absent or context_not_found would provide clearer insights into the nature of the error, especially in scenarios where resource errors are unlikely but possible.

@ccamel has suggested this enhancement for future consideration.
