Then she remembered: Andrwyd . Not a typo for Android. It was the name of a dead drop — an old weather station near the Arctic circle, decommissioned in 2015. And 2.3.6 were the coordinates: 2 km east, 3 km north, depth 6 meters. thmyl fysbwk layt andrwyd 2.3.6
A common assumption is that each word might be shifted by a certain number in the alphabet (Caesar cipher) or encoded with a simple substitution.
— meaning a short creative writing piece based on that string as a prompt. On the back, handwritten: "Thmyl fysbwk layt" —
But if it's Atbash (A↔Z, B↔Y, etc.): t (20) ↔ g (7), h (8) ↔ s (19), m (13) ↔ n (14), y (25) ↔ b (2), l (12) ↔ o (15) → gsnbo — no. Given the puzzle-like nature and the numbers 2.3.6 , it might be a book cipher — page 2, line 3, word 6 of some text. Or a software version "Andrwyd 2.3.6" (Android misspelled?).
Actually — I notice "thmyl" if each letter is shifted one forward in alphabet: t→u , h→i , m→n , y→z , l→m → uinzm — nonsense. Not a typo for Android
So here it is:
