Original question and givens

Elementary outcomes are Fin(1)={0,…,0}, with recording=[0] in original index order. Give (increasing distinct recording codes, aligned original-index fiber lists), sorting each fiber increasingly.

  • G001 — Elementary outcomes are Fin(1)={0,…,0}, with recording=[0] in original index order. Give (increasing distinct recording codes, aligned original-index fiber lists), sorting each fiber increasingly.

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

explicit finite possible-outcome protocol

After

no probability law,equiprobability or independence inferred

Conditions: none

These tasks list possible outcomes,recordings or event membership without assigning probabilities.All combinations being possible does not imply equiprobability or independence.

Step identifiers and dependencies

Rule: possible_outcomes_not_probabilities · Uses: G001

S002 · implies

Before

original outcome index=0∈[0]

After

recorded code=0

Conditions: none

Each original outcome has one code;different outcomes may share a code.Codes do not redefine original indices.

Step identifiers and dependencies

Rule: recording_total_mapping_row · Uses: G001, S001

S003 · implies

Before

recorded code=0

After

[0]

Conditions: none

List all original indices mapping to this code and align fibers with the sorted code list.

Step identifiers and dependencies

Rule: recording_preimage_fiber · Uses: G001, S002

Reverse checks

  • S003 · premise_and_result_audit — Check against the original data and this step's premises; a one-way implication is not an equivalence.
  • 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

([0], [[0]])

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