Original question and givens

Use ordered integer pairs in the same orthogonal directed xy frame. The origin lies on both axes; axis points are not in quadrants. P=[-5, 8], candidate=[9, -6], expected=(P.y,P.x). Give (expected list, candidate−expected component pair, is the candidate the true swap?, does P itself equal expected?).

  • G001 — Use ordered integer pairs in the same orthogonal directed xy frame. The origin lies on both axes; axis points are not in quadrants. P=[-5, 8], candidate=[9, -6], expected=(P.y,P.x). Give (expected list, candidate−expected component pair, is the candidate the true swap?, does P itself equal expected?).

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-density15-coordinate-swap-candidate-audit, density15_coordinate_swap_candidate_audit, finite_ordered_coordinate_protocol]

After

derived = [[expected_swap, candidate_minus_expected, candidate_matches, P_fixed]]

Conditions: none

density14/15 use FULL-prefix underscores;density17 uses LOCAL hyphens.The coordinate and circle frames differ.Retain THIS family ordered answer roles/types and all original bilingual JSON/status.

Step identifiers and dependencies

Rule: R60_EXACT_perbank_operation_domain_FRAME_and_output_roles · Uses: G001

S002 · calculation

Before

Coordinate swap candidate minus expected ORIGINAL P minus Q coordinate0 := sub(9, 8)

After

Coordinate swap candidate minus expected ORIGINAL P minus Q coordinate0 = 1

Conditions: none

Use ORIGINAL operands for exact integer/rational arithmetic.Only RAW inputs use SAFE or the explicit family bounds;derived values do not inherit those caps or use floating approximations.

Step identifiers and dependencies

Rule: exact_rational_arithmetic · Uses: G001, S001

S003 · calculation

Before

Coordinate swap candidate minus expected ORIGINAL P minus Q coordinate1 := sub(-6, -5)

After

Coordinate swap candidate minus expected ORIGINAL P minus Q coordinate1 = -1

Conditions: none

Use ORIGINAL operands for exact integer/rational arithmetic.Only RAW inputs use SAFE or the explicit family bounds;derived values do not inherit those caps or use floating approximations.

Step identifiers and dependencies

Rule: exact_rational_arithmetic · Uses: G001, S002

S004 · implies

Before

source roles = [Coordinate swap candidate minus expected, [9, -6], [8, -5]]

After

derived = [[1, -1]]

Conditions: none

THIS coordinate protocol retains both signs of ORIGINAL P-Q,OPPOSITE the length bank Q-P.A component difference is not distance or rendered size;derived values may exceed SAFE.

Step identifiers and dependencies

Rule: Coordinate_SOURCE_direction_PminusQ_not_length_QminusP · Uses: G001, S003

S005 · implies

Before

source roles = [[-5, 8], [9, -6]]

After

derived = [[8, -5], [1, -1], No, No]

Conditions: none

Expected is the ORIGINAL field swap(y,x),with residual candidate-expected.Candidate agreement and whether ORIGINAL P is a fixed point are SEPARATE flags.This data-field operation is not a formal reflection bridge.

Rule: Coordinate_SWAP_candidate_match_AND_ORIGINAL_fixedpoint_separate · Uses: G001, S004

Reverse checks

  • S005 · premise_and_result_audit — Reverse-check using the ORIGINAL data,types,indices and premises.Consistency auditing does not claim the conclusion uniquely determines its inputs.Keep finite candidates,independent review,formal proof and publication separate.
  • S004 · premise_and_result_audit — Reverse-check using the ORIGINAL data,types,indices and premises.Consistency auditing does not claim the conclusion uniquely determines its inputs.Keep finite candidates,independent review,formal proof and publication separate.
  • S003 · premise_and_result_audit — Recompute Coordinate swap candidate minus expected ORIGINAL P minus Q coordinate1 with exact rational arithmetic, not rounded decimals.
  • S002 · premise_and_result_audit — Recompute Coordinate swap candidate minus expected ORIGINAL P minus Q coordinate0 with exact rational arithmetic, not rounded decimals.
  • S001 · premise_and_result_audit — Reverse-check using the ORIGINAL data,types,indices and premises.Consistency auditing does not claim the conclusion uniquely determines its inputs.Keep finite candidates,independent review,formal proof and publication separate.

Result

([8, -5], [1, -1], No, No)

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