Induction proves,
from the subset {k:A(k)} of all j such that A(j)
being any inductive subset,
that the subset {k:A(k)} of all j such that A(j)
is the only.inductive subset.
That is something which induction can only prove
about a set which HAS an only.inductive subset.
ℕ has an only.inductive subset ℕ
If Z is inductive, then
⋂𝒫ⁱⁿᵈ(Z) has an only.inductive subset ⋂𝒫ⁱⁿᵈ(Z)
Being covered by induction is
being in the only.inductive.subset.

Consider the set {F} of all FISONs
and the set {F:A(F)} of all FISONs F′ such that A(F′)
Suppose we prove
/ first.{F} ∈ {F:A(F)}
\ if F′ ∈ {F:A(F)} then F′+1 ∈ {F:A(F)}
{F:A(F)} is one of the inductive subsets of {F}
{F} has only one inductive subset: {F}
We have proved {F:A(F)} = {F}
As a consequence of {F:A(F)} = {F}
∀F′ ∈ {F}: A(F′)
That is here the set of all FISONs.
{F} is not.in the only.inductive subset of {F}
Induction proves ∀F′ ∈ {F}: A(F′)
Induction doesn't prove A({F})
Each FISON is.
Some sets are and some sets aren't.

Which set do you have in mind?
{F} is a set of omissible FISONs.
{F} isn't an omissible set of FISONs.
Without the leap, there is no conflict.

No.

You (WM) imagine a last finite step,

However,
stepping.from the finite
