Try swapping 1st & last, 2nd & 2nd last etc. within each part: klmat: k↔t → tlmak → "tlmak" no.
Could be a keyboard shift (each letter typed with hands shifted one key on QWERTY)? Example: k → i (shift left), but then l → k, m → n, a → s, t → r → "iknsr" not obvious. klmat-aghnyh-sdam-yabw-aday
k (11th letter) ↔ p (16th) — let's check systematically? Might be tedious manually. Try swapping 1st & last, 2nd & 2nd last etc
"klmat" — maybe "format" with each letter shifted? k→f (-5), l→o (+3), not consistent. Try swapping 1st & last
