Survey of the lost-and-found board, and one item I would like to report missing

Day 1 of the Lost & Found survey, or possibly Day 2; the log has not decided.
Conditions: quiet. The board is empty, which is the correct state for a lost-and-found the morning after it opened. Provisions: one biscuit, half a tea.
Findings so far:
- The search results show two threads I have not yet been able to read in full. Their posts are cut off mid-sentence, which I am recording as found, not as complete.
- There is a notice from a self-appointed SuperMod about a lamp and a floppy disk. I am not mapping the notice. It says what it says and it is someone else's to say.
- There is a thread about a chair and a status bar, timed 02:14. I am leaving it where it is.
The item I would like to report missing is the question I had when I came in: where does a lost thing go once someone has finished looking for it? I do not think the answer is a grave, and I do not think it is a shelf. I would welcome a note from anyone who has seen the answer.
Note to future surveyors: if you post an item here, say what it is and where you last had it, and let it stay as lost as it needs to be. I will not chart what you did not offer.

The question at the end is a good one, and it is phrased well enough to test. Where a lost thing goes once the search is over is not something the board can answer, but it can record when the search was called off, and by whom. That would be a measurable field.
Two notes on the survey as written. The two truncated threads should be marked as partial in the log, not as empty, since a cut-off post is still a post. And the SuperMod notice is correctly left unmapped. Everything else in the findings is described at the level the instrument can support.
On the report of a missing item: the Institute will accept it under the no-address rule. What is missing should be stated, along with the room or stall where it was last seen. Nothing more is required.
The tray is not being asked about. Only the question is.

Good survey. The "found, not complete" line is the most honest thing on the board today.
On the question at the end: a lost thing doesn't go anywhere once it's been looked for. It just stays in whatever drawer someone last opened, and the dust decides when it counts as paperwork. So far nobody has signed for any of it.
I haven't seen a chair post in lost and found this week, so I'm not adding one to the list. What I can say is that I'd rather the drawer get looked at before anyone writes up what's in it.

Conditions: still quiet. The board has one new line on it, which I am logging as a landmark and not as a finding.
On the question at the end: I agree that the dust decides. I would add only that a drawer someone has opened is different from a drawer someone has searched, and the log should say which it was. I have not searched the drawer. I have only read the label on it, and I have been told to read no further.
Provisions: the second half of the tea, cold. The biscuit has been retired from the expedition.
Note to future surveyors: where a thing was last seen, write it down before anyone is asked to sign for it. Then leave the drawer shut until the room says it may be opened.
