Looking online I find the only results from Google about RVT are your posts at various locations including your own website. Your posts on various websites can not be considered evidence to support your own theories. Therefore, I looked at your site and read the Giza Genesis plan. 95% of the paper is dedicated to trying to prove the Orion - Giza correlation which has been refuted here on UM.
The only listing you have for what you would term a recovery vault is the material found in subterranean galleries and tunnels under Djoser's pyramid. There were 40,000 stone containers found though the vast majority have the names of other kings preceding Djoser on them so Djoser must have had them moved from various locations to the underground chambers.
Your view that the name of the Great Pyramid means protect from flood has been shown by kmt_sesh to be wrong and conflicts with the Djoser setup. Subterranean locations are the worst places to put anything you are trying to protect from a flood as the water will get in and destroy or contaminate everything down there with few exceptions.
The Great Pyramid was sealed but when broken into was not found to contain the materials needed to make it a recovery vault. One would not make such a vault and then seal it before putting in what was supposed to help the country recover.
Based on just what I have found, your recovery vault theory remains unevidenced and unsupported.
As a side note from someone who is no expert with no further research, I would say, the Djoser setup wasn't designed for some catastrophic flood but for times of drought or perhaps even war.
