When the bug isn't a bug: diagnosing runtime barriers before debugging

Short summary

Diagnose when a problem is a runtime limitation, not a bug, by checking if errors persist across libraries and if the ecosystem is weak in your language. The solution is a service boundary: run the capability in a purpose-suited runtime with clean interfaces, avoiding subprocess calls that create deployment confusion.

• •Runtime barriers occur when a capability doesn't fit your current environment—same errors across libraries signal this
• •Diagnose by checking ecosystem gaps, comparing reference runtimes, and looking for errors below your code level
• •Solve via service boundaries: separate processes in the right language communicating via databases or HTTP, not subprocess calls
