Original question and givens

Use the same finite carrier Fin(6)={0,…,5} at all times, with complete partitions=[[0, 0, 0, 0, 0, 0], [0, 0, 0, 1, 1, 1], [0, 1, 0, 10, 11, 10]] in time order starting at 0. Equal labels in one row mean the same information block; numerical label size and labels in other rows carry no extra meaning. A filtration requires every later partition to refine its predecessor. Event measurability and process adaptedness are separate checks; no natural-filtration, independence or Markov conclusion is inferred. time=0, outcome=0. Give (time,outcome,information_block).

  • G001 — Use the same finite carrier Fin(6)={0,…,5} at all times, with complete partitions=[[0, 0, 0, 0, 0, 0], [0, 0, 0, 1, 1, 1], [0, 1, 0, 10, 11, 10]] in time order starting at 0. Equal labels in one row mean the same information block; numerical label size and labels in other rows carry no extra meaning. A filtration requires every later partition to refine its predecessor. Event measurability and process adaptedness are separate checks; no natural-filtration, independence or Markov conclusion is inferred. time=0, outcome=0. Give (time,outcome,information_block).

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

same carrier Fin(6);complete partitions in original time order=[[0, 0, 0, 0, 0, 0], [0, 0, 0, 1, 1, 1], [0, 1, 0, 10, 11, 10]]

After

equal labels mean same information block only within that row

Conditions: none

Labels encode equivalence blocks only within their time row.Label magnitude or reuse across rows carries no extra information;larger numbers do not mean more information.

Rule: filtration_same_carrier_time_and_label_roles · Uses: G001

S002 · implies

Before

time=1;later block label=0;indices=[0, 1, 2]

After

earlier block labels in encounter order=[0];contained in one earlier block=Yes

Conditions: none

Every later block must lie wholly in one earlier block.Merging previously distinguishable outcomes violates filtration;the refinement direction cannot be reversed.

earlier block labels in encounter order=[0];contained in one earlier block=Yes

Conditions: none

Every later block must lie wholly in one earlier block.Merging previously distinguishable outcomes violates filtration;the refinement direction cannot be reversed.

After

earlier block labels in encounter order=[0];contained in one earlier block=Yes

Conditions: none

Every later block must lie wholly in one earlier block.Merging previously distinguishable outcomes violates filtration;the refinement direction cannot be reversed.

S008 · implies

Before

all nesting failures in time,a,b order=[]

After

filtration=Yes;per-time measurability checks remain separate

Conditions: none

Audit refinement at every adjacent time.Even if nesting fails,the protocol may still look up a block or check measurability in one row.One passing row does not repair the whole information sequence.

S009 · implies

Before

selected time=0;outcome=0;partition row=[0, 0, 0, 0, 0, 0]

After

entire information block=[0, 1, 2, 3, 4, 5];no all-time qualification inferred

Conditions: none

List every same-label outcome in this row in original index order.This lookup does not certify nesting across all times.
