Original question and givens

A process has 5 first-stage choices, but the number of second-stage options depends on the first choice and can be 5 or 6. May one fixed product be used unconditionally?

  • G001 — A process has 5 first-stage choices, but the number of second-stage options depends on the first choice and can be 5 or 6. May one fixed product be used unconditionally?

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 roles = [qf-basic-counting-principle, [branch_counts, conditional_stage_witness, mode, overlap_witness, stages]]

After

derived = [counting, null, null]

Conditions: none

Use THIS bank’s actual fields,operation/domain and types.BASE retains permissible extra metadata.Do not import LDL SAFE/set limits or a different bank’s deduplication rules.

Step identifiers and dependencies

Rule: R70_SOURCE_bank_specific_interface · Uses: G001

S002 · implies

Before

source roles = [5, 5, 6]

After

derived = [cannot multiply unconditionally]

Conditions: none

Two GIVEN conditional continuation counts differ,u≠v,so there is no common fixed b for an unconditional a·b total.A full total requires every first choice’s continuation count and summation.Unused stage metadata is not an extra premise.

Step identifiers and dependencies

Rule: Counting_CONDITIONAL_different_continuations_no_fixed_product · Uses: G001, S001

Reverse checks

  • S002 · premise_and_result_audit — Reverse-audit THIS question’s original operands,roles and necessary premises;reconstruct the next step,without reversing a one-way implication.Numerical/finite-table checking is not formal proof of an arbitrary theorem.Original Q,bilingual sources,MKO,AST,status and history remain preserved.
  • S001 · premise_and_result_audit — Reverse-audit THIS question’s original operands,roles and necessary premises;reconstruct the next step,without reversing a one-way implication.Numerical/finite-table checking is not formal proof of an arbitrary theorem.Original Q,bilingual sources,MKO,AST,status and history remain preserved.

Result

Cannot multiply unconditionally

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