Took me a bit longer to get this one but still quite simple overall.
Spent quite some time on getting to know the try and assert operators better.

Run with example input here

# Get the indices matching the ascending/
# descending criteria
CheckAsc ← ≡°□⍚(⍣(⊞⍀.≍⍆.)⍣(⊞⍀.≍⇌⍆.)0)
# Get the indices matching the distance criteria
CheckDist ← ≡°□⍚(⍣(⊞⍀.≠1∈:0)0×⊓≄≀1,3⌔⧈-)
Split     ← ⊙(▜≠1)â–œ,,

PartOne ← (
  &rs ∞ &fo "input-2.txt"
  ⊜(□⊜⋕≠@ .)≠@\n.
  CheckAsc.
  ▜
  CheckDist
  ⧻⊚
)

PartTwo ← (
  &rs ∞ &fo "input-2.txt"
  ⊜(□⊜⋕≠@ .)≠@\n.
  CheckAsc.
  Split
  CheckDist.
  Split
  ⊙(⊂)
  ⧻
  :
  ⍚(≡(â–œ:°⊟)⍜€⊞⊟:≠1⊞=.⇥⧻.)
  ≡(⧻⊚CheckDistâ–œCheckAsc.°□)
  +⧻◎⊚
)
