To improve it in order to ask next better question or supply better answer etc., is there a repository of such items for recycling/re-harvesting ? for back dated references?
Those items that may have been closed/deleted/ mis-posted and so on for whatever reason may still provoke subsequent ( after " thoughts in progress" stage ) remedial thoughts by the asker/answerer/commenter etc. A small part of what is "junked" may still be lucky for revival to become useful subsequently.
Not an answer, but a screen shot of what the moderator tools landing page looks like, depending on the tab selected there. Below is the contents of the current Delete tab. One can check for span of time over which to view posts, up to 30 days, and the downarrows allow one to expand to a larger list of posts in that time frame. One can also access "recently reopened" and "recently undeleted".
To access the mod tools, click on the upper right hand (background black) icon of a list with a checkmark (review queues). When you do that, users over 10k in rep will see something like:
Note the grey box in the upper right of the page: "Tools"
Click on the button to get to a page like the one you see above.
