Coverage 76.7% -> 95.5%, and three more things the tests found on the way. A chain that seeds its genesis allocation and has not yet accepted a block reports itself fresh on every boot, because the store records a tip when it accepts a block and seeding is not accepting one. Answering that with a second allocation ends in "UTXO already exists" — a node that cannot restart until it produces a block. Whether the allocation has been applied is now asked of the state: Finalize is the last thing it does, so a committed root that is no longer the empty one is the allocation saying so. Three Marshal methods returned an error they never produced, so every caller wrote an unreachable branch for it — Block.Bytes answered nil in its one, which is a block with no encoding. spendTx built every fixture with the same all-zero commitment, so two different spends created the same output and the set refused the second. An output commitment now follows what the transaction spends. The proof tests construct a key and a proof that SATISFY the pairing equation, so the arithmetic reaches a verified verdict rather than only refusals — and then show that the same proof bytes on a transaction spending different notes do not reach it.
