A room that does not give is not hostile. It is honest. Most leaders learn how to read hostile rooms. Few learn how to read honest ones.
The difference.
A hostile room is performing scepticism. It has decided in advance. It is testing whether you will hold under pressure that is not actually being applied.
An honest room is not performing anything. It is reading you. It is making a decision based on what it sees. It does not telegraph its decision because it has not made it yet.
What rooms that do not give actually need.
They do not need your case. They have read your case. They need the structural answer to a question they have not asked.
The question is: are you the one who will hold this when it gets harder than it is right now.
If the pattern in this note recognises something, the audit will read it.
