Here's the only issue we've faced with jumping right from Tactical to Governance if a Governance Tension came up in Tactical: NOTIFICATION.
If ALL the circle members are present, the Secretary could theoretically fulfill the requirement to reasonably notify circle members of the Governance meeting to take place immediately.
If ANY circle member is NOT present, they have not received notification, and so by extension they were not able to clarify, react and object to any proposal. We had this happen and STRUCK the resultant Governance as NVGO.
The same proposal then came up at the next 'properly notified' Governance meeting and was accepted again. This time is was valid.
