I had been trying to get Swirling Circuitry, but upgraded the coat of strange circuitry further instead:
You queue up a batch for Ancient Vault containing Offboard Command and Manual Search.
You move through the hall gingerly, neither stirring dust nor attracting attention from its keepers.
You command the vault to open and walk its halls.
You look over the data… so much of it has to do with your coat. It's not all obvious at first, but… yes and there are… yes and… aha!
The eyes peer into your programs as though judging you for the Secured Search you have not yet used.
The system takes note of your actions, increasing the Alert by 2.
You upgraded your equipped shirt to coat of defensive circuitry.
Possibly it upgraded because the command I used was offboard command. Also, this was at the Remote Pyramid site.
