Original question and givens

Use original bounded integer n=-1. Give (n, ordinary_positive_form_claim, sign_unit, absolute_prime_multiset, boundary).

  • G001 — Use original bounded integer n=-1. Give (n, ordinary_positive_form_claim, sign_unit, absolute_prime_multiset, boundary).

Definition and scope

Use the original question domain, assumptions and cited MKO definitions. This item has second-context mathematical and bilingual review, with the model, answer and every arithmetic step independently recomputed from the original parameters; the source question remains a candidate.

Step-by-step derivation

S001 · implies

Before

source operation=upf-unit-sign-boundary;original snapshot and mathematics retained

After

explicit ordered source output fields=[n, ordinary_positive_form_claim, sign_unit, absolute_prime_multiset, boundary]

Conditions: none

Retain the historical interface marker while listing ordered output fields without JavaScript.Fields and tags are not extra mathematical evidence;fixed No markers retain their claim scope.

Step identifiers and dependencies

Rule: source_ordered_interface_explicit_without_javascript · Uses: G001

S002 · implies

Before

ORIGINAL signed integer=-1;actual sign=-1;positive prime multiset=[]

After

ordinary_positive_form_claim fixed No;zero has no finite prime product;units use empty product1;nonzero sign is separated from |n| prime factors

Conditions: none

Zero is not a finite prime product;±1 are units with an empty prime multiset.Other nonzero integers separate sign from positive factors.The fixed No is not a positivity test or a denial of factorization for a positive integer.

Step identifiers and dependencies

Rule: upf_zero_units_sign_nonclaim_not_positive_test · Uses: G001, S001

Reverse checks

  • S002 · premise_and_result_audit — Check against the original data and this step's premises; a one-way implication is not an equivalence.
  • S001 · premise_and_result_audit — Check against the original data and this step's premises; a one-way implication is not an equivalence.

Result

(-1, No, -1, [], units_have_empty_prime_multiset)

The full substitutions and premise checks give the original answer; source identity,format and status are unchanged.
