Original question and givens
Use the whole real sequence a_n=L+c/(n+shift) for every n≥0, with L=13/14, positive c=13 and positive integer shift=2. The denominator shift is distinct from the theorem's supremum/infimum bound. The entire symbolic family, not a displayed finite prefix, supplies monotonicity and the corresponding bound. Give (direction, limit, coefficient, shift, first_three_terms, symbolic_certificate, certificate).

Step-by-step derivation
S001 · implies
Before
source operation=monoseq-decreasing-limit-certificate;original snapshot and mathematics retained
After
explicit ordered source output fields=[direction, limit, coefficient, shift, first_three_terms, symbolic_certificate, certificate]
Conditions: none
Retain the historical interface marker while listing ordered output fields without JavaScript.Fields and tags are not extra mathematical evidence;fixed No markers retain their claim scope.

S002 · implies
Before
ORIGINAL direction=decreasing,L=13/14,c=13>0,shift=2>=1;WHOLE a_n=L+(1)c/(n+shift) for ALL n>=0
After
for EVERY n>=0,a_(n+1)-a_n=(-1)*(13)/((n+2)*(n+1+2));positive denominator;all a_n strictly above L=13/14
Conditions: none
Subtract adjacent symbolic terms using a common denominator.Positivity fixes the sign and gives upper bound L in the increasing case or lower bound L in the decreasing case.This holds for all n,allows negative L,and is not a three-term sample proof.

S003 · implies
Before
WHOLE decreasing law with ORIGINAL L=13/14,c=13,shift=2
After
for ANY epsilon>0 choose natural N with N+2>13/epsilon;ALL n>=N have |a_n-L|<epsilon;L is infimum but NOT attained because c/(n+shift)>0
Conditions: none
The Archimedean choice controls every later term.Any smaller upper bound or larger lower bound is broken by a term sufficiently close to L,so L is the sup/inf.In the general monotone theorem,sup−epsilon is not an upper bound,which supplies a term;monotonicity then traps the tail.The decreasing proof is dual.
