I tried the following tests and they all pass:

// $ExpectType { a: boolean; }
S.evolve({ a: 1 }, {
  a: (
    n // $ExpectType number
  ) => n > 0
})

// $ExpectType { a: boolean; }
pipe(
  { a: 1 },
  S.evolve({
    a: (
      n // $ExpectType number
    ) => n > 0
  })
)

// $ExpectType { a: number; b: number; }
S.evolve(
  { a: "a", b: 1 },
  {
    a: (
      s // $ExpectType string
    ) => s.length
  }
)

// $ExpectType { a: number; b: number; }
pipe(
  { a: "a", b: 1 },
  S.evolve({
    a: (
      s // $ExpectType string
    ) => s.length
  })
)

// @ts-expect-error
S.evolve({ a: "a", b: 1 }, { a: (n: number) => n })

// @ts-expect-error
S.evolve(hole<{ a: "a"; b: 1 }>(), hole<Record<string, string>>())

// @ts-expect-error
S.evolve(hole<{ a: "a"; b: 1 }>(), hole<Record<string, (s: string) => null>>())

// @ts-expect-error
pipe({ a: "a", b: 1 }, S.evolve({ a: (n: number) => n }))

// @ts-expect-error
pipe(hole<{ a: "a"; b: 1 }>(), S.evolve(hole<Record<string, string>>()))

// @ts-expect-error
pipe(hole<{ a: "a"; b: 1 }>(), S.evolve(hole<Record<string, (s: string) => null>>()))

for me, it's ok
