Bug-out Shelter #2 - First clues

Mission

Once you have identified the GPS coordinates, you set about checking what this location corresponds to. The shelter's digital archives, fragmented and incomplete, still contain a few reports on military infrastructure from before the fall. You search extensively, cross-referencing files, technical reports, and old strategic plans.

Gradually, a certainty emerges: the coordinates refer to a major military station, the central point of a vast post-nuclear survival program. This base would have been used to supervise the construction of shelters and maintain a form of administrative oversight.

As you explore further, you come across an encrypted register, presumably taken from this station. The characters are scrambled and incomplete, but the organization into lines suggests a list of names. To understand its contents, you need to decipher this register and compare it carefully with the official registers of the Prometheus shelter.

Rules

You have two variables at your disposal:

• message: contains the encrypted log to be analyzed
• log: contains an extract from the Prometheus shelter log

You must return the (decrypted) first names of the inhabitants found in the log. In the order in which they appear in the message.
