Original question and givens

Use mode=moving_spike, positive integer scale=9, and the full sequence/domain description in the result. Give (mode, scale, sequence_description, scope_or_obstruction, theorem_application_claim).

  • G001 — Use mode=moving_spike, positive integer scale=9, and the full sequence/domain description in the result. Give (mode, scale, sequence_description, scope_or_obstruction, theorem_application_claim).

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 = [uniform-limit-boundary]

After

derived = [[mode, scale, sequence_description, scope_or_obstruction, theorem_application_claim]]

Conditions: none

List the complete source field order and mode-specific roles without JavaScript or answer-shape inference;No,undefined and infinity retain their distinct meanings.

Step identifiers and dependencies

Rule: source_ordered_fields_without_JS · Uses: G001

S002 · implies

Before

source roles = [moving_spike, 9]

After

derived = [moving_spike, 9, f_n(x)=max(0,1-(n+9)*abs(x-1/(n+9)))_on_[0,1], continuous_pointwise_to_zero_but_sup_norm_one, No]

Conditions: none

Powers tend to0 for x<1 but equal1 at x=1,so convergence is only pointwise.A constant step sequence is uniform but its terms are discontinuous.A finite grid can miss a unit bump between points.A moving spike is continuous,attains1 at its moving peak and eventually vanishes at each fixed x,so its sup error stays1.No rejects the theorem premises/method,not every underlying convergence claim or a performed formal proof.

Step identifiers and dependencies

Rule: Uniform_original_WHOLE_boundary_premise_obstruction · Uses: G001, S001

Reverse checks

  • S002 · premise_and_result_audit — Reverse-check the complete original data,step operands and premises;finite checks,conditional named-theorem use and general formal proof remain distinct.
  • S001 · premise_and_result_audit — Reverse-check the complete original data,step operands and premises;finite checks,conditional named-theorem use and general formal proof remain distinct.

Result

(moving_spike, 9, f_n(x)=max(0,1-(n+9)*abs(x-1/(n+9)))_on_[0,1], continuous_pointwise_to_zero_but_sup_norm_one, No)

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