Use coordinate bounds lower=[-6, -7, -8],upper=[7, 8, 9], start=[-5, -6, -7],end=[6, 7, 8]. Give (lower, upper, start, end, coordinate_formulas, range_certificate, certificate).
G001 — Use coordinate bounds lower=[-6, -7, -8],upper=[7, 8, 9], start=[-5, -6, -7],end=[6, 7, 8]. Give (lower, upper, start, end, coordinate_formulas, range_certificate, certificate).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
source roles = [path-box-linear]
After
derived = [[lower, upper, start, end, formulas, continuous_path, certificate]]
Conditions: none
List this operation/mode exact source field order without JavaScript.Keep Boolean,string and null roles distinct;do not pad fields or infer the interface from answer shape.
Rule: source_ordered_fields_without_JS · Uses: G001
Before
source roles = [[-6, -7, -8], [7, 8, 9], [-5, -6, -7], [6, 7, 8]]
After
derived = [3, Yes]
Conditions: none
Check both endpoints against each coordinate interval with matching dimensions.Degenerate coordinates and reverse orientation are allowed.
Rule: Path_ALL_coordinate_endpoint_premises · Uses: G001, S001
Before
Path coordinate0 ORIGINAL end minus start := sub(6, -5)
After
Path coordinate0 ORIGINAL end minus start = 11
Conditions: none
Substitute the original roles exactly,retaining symbolic operations;no floating approximation or extra source-domain restriction.
Rule: exact_rational_arithmetic · Uses: G001, S002
Before
source roles = [0, -6, 7, -5, 6, 11]
After
derived = [gamma_i(t)=(1-t)*start_i+t*end_i, 0<=t<=1, -6, 7, -5, 6]
Conditions: none
For every t in[0,1],weights(1-t),t are nonnegative and sum to1.Thus this coordinate lies between its endpoints and within its bounds;the affine coordinate is continuous,not merely endpoint-checked.
Rule: Path_WHOLE_coordinate_convex_range_and_continuity · Uses: G001, S003
Before
Path coordinate1 ORIGINAL end minus start := sub(7, -6)
After
Path coordinate1 ORIGINAL end minus start = 13
Conditions: none
Substitute the original roles exactly,retaining symbolic operations;no floating approximation or extra source-domain restriction.
Rule: exact_rational_arithmetic · Uses: G001, S004
Before
source roles = [1, -7, 8, -6, 7, 13]
After
derived = [gamma_i(t)=(1-t)*start_i+t*end_i, 0<=t<=1, -7, 8, -6, 7]
Conditions: none
For every t in[0,1],weights(1-t),t are nonnegative and sum to1.Thus this coordinate lies between its endpoints and within its bounds;the affine coordinate is continuous,not merely endpoint-checked.

Before
Path coordinate2 ORIGINAL end minus start := sub(8, -7)
After
Path coordinate2 ORIGINAL end minus start = 15
Conditions: none
Substitute the original roles exactly,retaining symbolic operations;no floating approximation or extra source-domain restriction.
Rule: exact_rational_arithmetic · Uses: G001, S006

Conditions: none
For every t in[0,1],weights(1-t),t are nonnegative and sum to1.Thus this coordinate lies between its endpoints and within its bounds;the affine coordinate is continuous,not merely endpoint-checked.
