No document for this exists in the corpus yet. Dead end means "not yet ingested and navigable" — never "hidden."
There is no county appropriation. Middlesex County government was abolished on July 11, 1997; its functions passed to the Commonwealth of Massachusetts. Here a dead end means the thing itself no longer exists at the county level — the honest answer, not a gap in our records.
Reconstructed — and the trail stops here. To see who this money actually reached, someone has to pull records, minutes, or a check register. It often stays dark.
There's another way. If the county paid this line from a transparent, line-attributed account, it would publish its own itemized transactions — payee, amount, date — the moment each payment cleared. No request required; the dead end becomes a list. That's the idea behind receipts by rails, filed as a solution to the transparency question — read it and weigh in.
