Ordered second-stage branch counts=[], n=0; candidate common width h=7. Give (actual total, assumed n*h total, does every branch equal h?, n*h−actual total).
G001 — Ordered second-stage branch counts=[], n=0; candidate common width h=7. Give (actual total, assumed n*h total, does every branch equal h?, n*h−actual total).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.
Before
declared finite tagged choices or full-product protocol
After
combinatorial counts,not probabilities or independence
Conditions: none
Addition uses disjoint tags and multiplication uses the declared full cross-stage protocol;neither is a probability-independence assumption.
Rule: finite_counting_protocol_scope · Uses: G001
Before
actual branch total := sum()
After
actual branch total = 0
Conditions: none
Add the actual widths of the conditional branches.
Rule: exact_rational_arithmetic · Uses: G001, S001
Before
assumed common-width total := mul(0, 7)
After
assumed common-width total = 0
Conditions: none
Separately compute n times candidate width h without yet asserting equal branch widths.
Rule: exact_rational_arithmetic · Uses: G001, S002
Before
assumed minus actual total := sub(0, 0)
After
assumed minus actual total = 0
Conditions: none
The signed defect is assumed n·h minus the actual total.
Rule: exact_rational_arithmetic · Uses: G001, S003
Before
branch comparisons=[]
After
all equal h=Yes
Conditions: none
With no first-stage branches,the width universal is vacuously true but the actual count is0;this differs from a zero-stage full product's single empty sequence.
Rule: uniform_width_not_aggregate_equality · Uses: G001, S004
S005 · premise_and_result_audit — Check against the original data and this step's premises; a one-way implication is not an equivalence.S004 · premise_and_result_audit — Recompute assumed minus actual total with exact rational arithmetic, not rounded decimals.S003 · premise_and_result_audit — Recompute assumed common-width total with exact rational arithmetic, not rounded decimals.S002 · premise_and_result_audit — Recompute actual branch total with exact rational arithmetic, not rounded decimals.S001 · premise_and_result_audit — Check against the original data and this step's premises; a one-way implication is not an equivalence.(0, 0, Yes, 0)
The full substitutions and premise checks give the original answer; source identity,format and status are unchanged.
