Your name is Aöuieue Űai, you've embraced transcendence of the gender binary since a very early age, and thanks to your grandfather's crimes and the terrible labour policies of the Confederation's central government, you have been conscripted to work as a Relic Investigator, Tenth Class on the Delta Nine Reliquary.
Based on deep analysis of your social media accounts – yes, despite them being friends-locked and heavily encrypted, apparently the Ministry of Labour is allowed to backdoor people's devices – the system has concluded that your principal interest is in relics which are older than the universe. You can't say it's actually wrong; you'd always thought that nothing could possibly pre-date Event Zero, but apparently it's not bullshit, there's hard evidence that the achronal voids some relics were recovered from are that old.
After a week of being poked, prodded, scanned, fitted with a brain implant that stops you trying to get out of doing your job by killing yourself (you never knew they took draft-dodging that seriously, and you're faintly horrified that it's not illegal), and given pieces of paper to sign acknowledging that you are a conscript, that your residual after-tax salary is ten times what you were making as a tour guide back home, that your little sister is your oldest surviving relative descended from your grandfather, that you are entitled to free room and board for your entire contract term, and so forth, you are sitting at a workbench.

The relic in front of you is a matte beige box of a material that feels like a synthetic polymer, but clearly can't be if it's as old as it's supposed to be. On one of the large square faces of the box, there are ten circles of crosshatched engraving arranged as a 3x3 grid with one number below. The previous investigator – your grandfather – has put self-adhesive labels numbered 0-9 on the buttons. Three metal rods with rounded ends stick out of the 7/8/9 edge of the box, running in line with the 1-4-7, 0-2-5-8, and 3-6-9 columns of numbers.
There's a list of combinations written in your grandfather's notes. Many sequences just result in a clicking sound. Pressing all the "buttons" in a single column seems to make the matching rod glow for a few seconds, after which the box makes a clicking sound. An annotation in different writing, following your grandfather's last note, reports that at the end of his final session with the relic, your grandfather pressed the '9' button ten times in a row, all three rods glowed for five seconds, and your grandfather pressed them to his forehead while they were glowing.
You realize nobody has actually told you how your grandfather died.
You have a relic. You are expected to investigate it.
[X] Corroborate some of your grandfather's notes. (But definitely not the bit from the other investigator's notes about spamming '9'.)
[X] Press all the buttons in numerical order. (Apparently your grandfather never tried this, or if he did, he didn't write down what happened.)
[X] Try seeing if the rods will unscrew.
[X] Requisition some inert test materials and press the rods against them while they're glowing.
