Ports 8080 and 23456 now explicitly forbidden in sandbox expose list
BreakingBreaking change
This is a breaking change — integrations that rely on the affected behaviour will need updates before the change rolls out.
What changed
The not constraint on sandbox exposed port numbers has been tightened to explicitly exclude ports 8080 and 23456. Previously, "not": {} was an empty schema (which never matched anything, effectively a no-op), so any port in the valid range was accepted. Now "not": {"enum": [8080, 23456]} actively rejects those two specific values — clients currently passing 8080 or 23456 in the ports array will receive validation errors.
