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.

ORIGINAL mode=finite_prefix_only;displayed prefix length=14;prefix_or_length=14
After
ONLY prefix length given;NO infinite continuation specified;all three flags WITHHOLD certificates,not classify unknown continuations
Conditions: none
Distinguish a whole-sequence formula from a finite length.In the first two cases,monotonicity,bounds and divergence follow from the declared infinite law and explicit witnesses,not the displayed prefix.
ORIGINAL boundary mode=finite_prefix_only;actual certificate flags=(No, No, No)
After
monotone convergence theorem not certified here;convergence in GENERAL does NOT imply monotonicity;unknown continuation not declared divergent
Conditions: none
Monotonicity and the matching bound are sufficient for this theorem,not necessary for every convergent sequence.A finite-prefix No does not make all extensions divergent;the specified alternating example has its own even/odd divergence witness.
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
(finite_prefix_only, 14, No, No, No, finite_prefix_not_universal_monotone_bounded_certificate)
The full substitutions and premise checks give the original answer; source identity,format and status are unchanged.
