"An offering the king gives to Osiris, foremost of the westerners, lord of Djedu, a voice offering [of bread and beer] for him at every festival and every day..."
and then it cuts off. I'd expect the inscription to continue stating that these offerings are for the spirit of the tomb's owner, along with a list of some of his offices. I spot similar offerings to Anubis. I spot the epithet "venerable", indicating that the tomb owner had a funerary cult.
Regarding the meaning of objects found I want to share this humorous story in which future archaeologists find a motel room and they believe to have found a great tomb similar to that of Tutankhamun:
"Motel of the Mysteries"
