    * Of the United States Court of International Trade, sitting
    by designation.
    SELYA,      Circuit Judge.           Plaintiff-appellant Wanda E.
    Daumont-Colón       (Daumont)    asserts      that    she    was   fired      from   her
    position as a branch manager for defendant-appellee Cooperativa de
    Ahorro y Crédito de Caguas (the Credit Union) because of her age.
    The Credit Union demurs, asserting that Daumont was discharged
    because of a material breach of its rules of conduct.                   A jury trial
    ensued and, at the close of Daumont's evidence, the district court
    granted the Credit Union's motion for judgment as a matter of law.
    See Fed. R. Civ. P. 50(a).         On appeal, Daumont challenges what she
    characterizes as the district court's misapplication of the law of
    the case doctrine, its exclusion of evidence as to the discipline
    meted out to other employees, and its determination that she failed
    to   present   facts      sufficient     to   take     her    case     to    the   jury.
    Concluding,    as    we   do,    that   Daumont      is     foraging    in    an   empty
    cupboard, we affirm.
    I. BACKGROUND
    Many of the facts are uncontroverted and were stipulated
    by   the   parties.         We    supplement         that    account        with   other
    uncontroversial facts, mindful that the nub of the parties' dispute
    is not on the raw facts, but on what those facts signify.
    The Credit Union is located in Caguas, Puerto Rico, and
    offers financial services to its members.                      In March of 2015,
    Daumont — then sixty years of age — was serving as the branch
    manager for one of the Credit Union's branches.                        Irma Hilerio-
    - 2 -
    Arroyo (Hilerio) was the Credit Union's chief executive officer
    (with the title of "Executive President").1
    The events leading up to Daumont's dismissal can be
    succinctly summarized.           On February 20, 2015, Daumont was at work
    when she received a telephone call from her husband, José Tirado,
    who was a long-time member of the Credit Union.                       Tirado asked
    Daumont to withdraw eighty dollars from his line of credit at the
    Credit Union and deposit it into his checking account.                     Daumont
    proceeded to fill out a withdrawal slip and, on the line provided
    for the member's signature, signed Tirado's name.                     Daumont then
    gave       the   withdrawal     slip   to    a   teller,   Norberto   Santos,   and
    instructed him to obtain the necessary authorization for the
    transaction.
    At trial, Santos testified that he could not recall
    whether      he    tried   to   obtain      authorization    from   his   immediate
    supervisor, Joanny Torres.               What is clear, though, is that the
    transaction was never properly authorized. And once Torres learned
    of the transaction, she brought it to the attention of Ramon
    Adorno, vice president of operations.                  At a later meeting with
    Adorno, Daumont admitted that she had signed Tirado's name to the
    withdrawal slip. She added that she had signed for Tirado on prior
    1
    Daumont's suit named both the Credit Union and Hilerio as
    defendants. On appeal, Daumont does not press any particularized
    claims against Hilerio. For ease in exposition, then, we refer
    throughout to the Credit Union as if it were the sole defendant.
    - 3 -
    occasions and represented that she was on file with the Credit
    Union as an "authorized signature" for Tirado's line of credit.
    On March 10, 2015, Daumont was discharged by the Credit
    Union.   In a letter from Hilerio, she was told that her dismissal
    stemmed from signing Tirado's name to withdrawal slips, which
    violated (among other things) the Credit Union's rules against
    offering false information on official documents.      Pertinently,
    Hilerio's letter noted that those rules called for an employee's
    firing after a single offense of this genre and that, in all
    events, the Credit Union's investigation had revealed that Daumont
    was not an authorized signatory on Tirado's line of credit.
    Daumont did not go quietly.    Instead, she brought suit
    in the federal district court pursuant to the Age Discrimination
    in Employment Act (ADEA), 
    29 U.S.C. § 623
    (a)(1), which prohibits
    adverse employment actions against any individual when carried out
    "because of such individual's age."     Her complaint also set forth
    a medley of supplemental claims under Puerto Rico law. The parties
    consented to proceed before a magistrate judge.       See 
    28 U.S.C. § 636
    (c); Fed. R. Civ. P. 73.    After the close of discovery, the
    Credit Union moved for summary judgment.    See Fed. R. Civ. P. 56.
    The district court jettisoned two of Daumont's claims (neither of
    which is implicated on appeal) but otherwise denied the motion.
    See Daumont-Colón v. Cooperativa de Ahorro y Crédito de Caguas,
    No. 15-3120, 
    2018 WL 10741870
    , at *4-6 (D.P.R. May 9, 2018).
    - 4 -
    The   Credit    Union   subsequently     moved    in   limine   to
    exclude,   among   other      things,   Daumont's    proffered       evidence
    concerning the Credit Union's allegedly disparate treatment of
    younger employees who had engaged in misconduct.               The district
    court denied this motion without prejudice.         See Daumont-Colón v.
    Cooperativa de Ahorro y Crédito de Caguas (Daumont I), No. 15-
    3120, 
    2019 WL 8808083
    , at *1 n.1 (D.P.R. June 12, 2019).
    During the trial, Daumont admitted that she had signed
    withdrawal slips in Tirado's name not only on February 20, 2015,
    but also on seven previous occasions.         Tirado confirmed that he
    had verbally authorized the transactions, and Santos testified as
    to his role in effectuating the February 20 withdrawal.                    By
    agreement, the Credit Union's rules of conduct were introduced as
    an   exhibit.    But   when   Daumont   attempted    to     adduce   evidence
    concerning discipline meted out to other employees for different
    kinds of infractions, the Credit Union renewed its objection to
    the introduction of the challenged evidence.                This time, the
    district court — first ruling ore sponte and then elaborating its
    reasoning in a written rescript filed in connection with Daumont's
    motion for reconsideration — excluded the comparator evidence,
    primarily because the other employees were not similarly situated
    to Daumont in material respects.        See 
    id. at *2
    .
    Once Daumont rested, the Credit Union moved for judgment
    as a matter of law.    See Fed. R. Civ. P. 50(a).      The district court
    - 5 -
    granted the motion.    See Daumont-Colón v. Cooperativa de Ahorro y
    Crédito de Caguas (Daumont II), No. 15-1320, 
    2019 WL 8809765
    , at
    *1 (D.P.R. June 14, 2019).           The effect of this ruling was to
    dismiss with prejudice all of Daumont's remaining claims under
    both the ADEA and Puerto Rico law.           See 
    id. at *5
    .       This timely
    appeal followed.
    II. ANALYSIS
    Daumont's asseverational array begins with a claim that
    the district court contradicted the law of the case doctrine when
    — after denying the Credit Union's pretrial motions in limine and
    for   summary   judgment   —    it   excluded   her   proffered    comparator
    evidence at trial and eventually granted the Credit Union's Rule
    50(a) motion.     Next, Daumont challenges those latter rulings on
    their merits.    We consider these claims of error sequentially.
    A.   Law of the Case.
    Daumont insists that when the district court ruled in
    her favor on the Credit Union's motion in limine and its motion
    for summary judgment, those decisions became binding as the "law
    of the case."      Because none of the "exceptional circumstances"
    permitting a court to deviate from the law of the case doctrine
    was in play, United States v. Matthews, 
    643 F.3d 9
    , 14 (1st Cir.
    2011), the district court (in her view) was not at liberty either
    to exclude her comparator evidence at trial or to grant the Credit
    Union's Rule 50(a) motion.       We do not agree.
    - 6 -
    The essence of the law of the case doctrine is the notion
    that "when a court decides upon a rule of law, that decision should
    continue to govern the same issues in subsequent stages in the
    same case."   Arizona v. California, 
    460 U.S. 605
    , 618 (1983).        In
    practice, though, the doctrine has two separate branches.            See
    United States v. Moran, 
    393 F.3d 1
    , 7 (1st Cir. 2004).        The first
    branch, known as the mandate rule, constrains trial courts in the
    aftermath of appellate rulings.         See 
    id.
         That branch is not
    implicated here.
    "The second branch contemplates that a legal decision
    made at one stage of a criminal or civil proceeding should remain
    the law of that case throughout the litigation, unless and until
    the decision is modified or overruled by a higher court."             
    Id.
    This aspect of the doctrine is "prudential" and, thus, "more
    flexible" than the mandate rule. 
    Id.
     Especially because the Civil
    Rules authorize district courts to revise their own orders and
    decisions at any time before entering final judgment, see Fed. R.
    Civ. P. 54(b), such interlocutory rulings ordinarily "do not
    constitute the law of the case," Harlow v. Children's Hosp., 
    432 F.3d 50
    , 55 (1st Cir. 2005) (quoting Pérez-Ruiz v. Crespo-Guillén,
    
    25 F.3d 40
    , 42 (1st Cir. 1994)).         At least in the absence of
    extraordinary   circumstances   (and    no   such   circumstances   exist
    here), the law of the case doctrine is inherently discretionary
    insofar as it affects a trial court's power to revisit its prior
    - 7 -
    interlocutory orders.          See 
    id. at 55-56
    .         Against this backdrop,
    we have said that a trial court's decision to revisit its earlier
    rulings is reviewable only for "particularly egregious" abuses of
    discretion.       
    Id. at 56
    .
    Seen in this light, Daumont's argument is hopeless.               The
    record in this case reflects nothing more than a routine exercise
    of the district court's discretion. Take, for example, the court's
    decision to grant judgment as a matter of law after previously
    denying the same party's motion for summary judgment. As a general
    matter, it is unremarkable to grant a party's motion for judgment
    as a matter of law after having denied that party's motion for
    summary judgment.          See, e.g., Delgado v. Pawtucket Police Dep't,
    
    668 F.3d 42
    , 44-45 (1st Cir. 2012); Wilson v. Moreau, 
    492 F.3d 50
    ,
    52 (1st Cir. 2007); cf. Flibotte v. Pa. Truck Lines, Inc., 
    131 F.3d 21
    ,    25    (1st    Cir.    1997)   (characterizing      as    "perfectly
    appropriate" granting of judgment notwithstanding the verdict
    after court earlier had denied motion for directed verdict).
    Although the district court's task is much the same at both stages,
    the evidence that it may properly consider is not:                    motions for
    summary judgment are decided based on affidavits and other pretrial
    filings, whereas motions for judgment as a matter of law are
    "decided     on    the   evidence    that   has   been    admitted"    at   trial.
    Anderson v. Liberty Lobby, Inc., 
    477 U.S. 242
    , 251 (1986) (quoting
    Bill Johnson's Rests., Inc. v. NLRB, 
    461 U.S. 731
    , 745 n.11
    - 8 -
    (1983)).     Those bodies of evidence may be similar, but in the
    typical case — as here — they are not identical.      See Thorpe v.
    Mut. of Omaha Ins. Co., 
    984 F.2d 541
    , 545 (1st Cir. 1993).
    Much the same reasoning applies to the district court's
    revisiting of the Credit Union's objections to the comparator
    evidence.    The district court explained that it originally denied
    the Credit Union's motion in limine mainly because it considered
    exclusion "to be premature" at that juncture.    Daumont I, 
    2019 WL 8808083
    , at *1 n.1; cf. Fusco v. Gen. Motors Corp., 
    11 F.3d 259
    ,
    263 (1st Cir. 1993) (acknowledging that courts hesitate to exclude
    evidence before trial because "many issues are best resolved in
    context and only when finally necessary").      By not definitively
    excluding the evidence through a pretrial ruling, the district
    court gave Daumont an opportunity to put her best foot forward and
    establish, in the setting of the trial, why the proffered evidence
    satisfied applicable standards of relevance and probative value.
    At the same time, the court gave itself "a chance to reconsider
    the ruling with the concrete evidence presented" at trial.   Fusco,
    
    11 F.3d at 262
    .       Even if Daumont's proffer at trial remained
    substantially identical to her proffer at the motion-in-limine
    stage, the district court remained "free, in the exercise of sound
    judicial discretion, to alter [its] previous in limine ruling."
    Luce v. United States, 
    469 U.S. 38
    , 41-42 (1984) (emphasis in
    original).     It follows that the law of the case doctrine did not
    - 9 -
    foreclose the district court's reappraisal of the admissibility of
    the proffered comparator evidence.
    B.    Exclusion of Comparator Evidence at Trial.
    Daumont   contends    that   even   if    the   district   court's
    denial of the Credit Union's motion in limine did not constitute
    the law of the case, the court nonetheless erred in refusing to
    admit her proffered comparator evidence at trial.           This evidence,
    she says, would have shown disparate treatment and, thus, would
    have given the jury a basis for finding that the Credit Union's
    stated ground for her discharge was pretextual.
    On appeal, "[w]e review rulings admitting or excluding
    evidence for abuse of discretion." Downey v. Bob's Disc. Furniture
    Holdings, Inc., 
    633 F.3d 1
    , 8 (1st Cir. 2011).                  Under this
    deferential standard, "we may overturn a challenged evidentiary
    ruling only if it plainly appears that the court committed an error
    of law or a clear mistake of judgment."         Torres-Arroyo v. Rullán,
    
    436 F.3d 1
    , 7 (1st Cir. 2006).
    To   support   an    inference   of      discriminatory    animus,
    evidence that an employer has engaged in disparate treatment "must
    rest on proof that the proposed analogue is similarly situated in
    material respects."   Vélez v. Thermo King de P.R., Inc., 
    585 F.3d 441
    , 451 (1st Cir. 2009) (quoting Perkins v. Brigham & Women's
    Hosp., 
    78 F.3d 747
    , 751 (1st Cir. 1996)). "[W]hile the plaintiff's
    case and the comparison cases that [she] advances need not be
    - 10 -
    perfect replicas, they must closely resemble one another in respect
    to relevant facts and circumstances."           Conward v. Cambridge Sch.
    Comm., 
    171 F.3d 12
    , 20 (1st Cir. 1999).
    Here, Daumont avers that the district court applied the
    wrong   legal   standard,    requiring    her   to    show   that   the   other
    employees' circumstances were "almost identical" to her own.                She
    also avers that the court's determination that the proffered
    evidence lacked probative value usurped what should have been a
    question of fact for the jury.            And, finally, she argues that
    because the Credit Union's policies state that its disciplinary
    procedures are to be applied uniformly to all employees, the court
    abused its discretion in not weighing the other employees' actions
    against her own to gauge their "comparative seriousness."
    In our view, the district court did not abuse its
    discretion in excluding Daumont's proffered comparator evidence.
    To begin, Daumont's contention that the district court applied an
    overly stringent "almost identical" standard to her comparator
    evidence appears to derive from language used by the court at
    sidebar in a discussion of the use of comparator evidence.                But as
    virtually everyone experienced in trial practice knows, judges'
    extemporaneous    comments    at   sidebar      are   sometimes     imprecise.
    Unless there is good reason to believe that such an imprecise
    statement affected a party's substantial rights, it should not be
    accorded decretory significance.         See, e.g., Lenn v. Portland Sch.
    - 11 -
    Comm., 
    998 F.2d 1083
    , 1087-88 (1st Cir. 1993) (concluding that,
    given   totality    of   circumstances,     an   "infelicitous   choice    of
    phrase" does not indicate that trial court deviated from "proper
    rule of decision"); cf. Loja-Tene v. Barr, 
    975 F.3d 58
    , 61 n.2
    (1st Cir. 2020) (treating isolated misstatement of legal standard
    by Board of Immigration Appeals as "lapsus linguae" and refusing
    to accord it "dispositive weight"). In this instance, the critical
    datum is that the district court, in making its exclusionary
    ruling, faithfully recited and applied the correct legal standard.
    See Daumont I, 
    2019 WL 8808083
    , at *2; see also Perkins, 
    78 F.3d at 751
     (explicating "similarly situated in material respects"
    standard).    We therefore reject Daumont's claim of error.
    This   brings   us   to    Daumont's   contention   that     the
    determination of whether the employees to whom the comparator
    evidence related were similarly situated to her was a question of
    fact for the jury.       It is true, of course, that juries serve as
    factfinders and, in that capacity, are entitled to weigh properly
    admitted evidence and to draw reasonable inferences therefrom.
    See, e.g., Blake v. Pellegrino, 
    329 F.3d 43
    , 47 (1st Cir. 2003).
    But the Federal Rules of Evidence entrust district courts with
    threshold issues as to the admissibility of evidence, including
    issues of relevance and the balancing of probative value and
    unfairly prejudicial effects.          See Fed. R. Evid. 401, 403.      Such
    issues must be determined on a case-by-case basis, in light of
    - 12 -
    both the particular factual context and the applicable law.              See,
    e.g., Franchina v. City of Providence, 
    881 F.3d 32
    , 49 (1st Cir.
    2018); United States v. Mehanna, 
    735 F.3d 32
    , 61 (1st Cir. 2013).
    Our   case     law   teaches    that     an   employer's   relative
    leniency   toward   one    employee   is     only   persuasive    evidence   of
    discrimination with respect to disciplinary action taken against
    a plaintiff-employee if the factfinder may reasonably infer from
    material similarities between the circumstances of the two that
    the   discrepancy   was    likely     correlated     with   the   plaintiff's
    protected characteristic.       See Dartmouth Rev. v. Dartmouth Coll.,
    
    889 F.2d 13
    , 19 (1st Cir. 1989) ("Much as in the lawyer's art of
    distinguishing cases, the 'relevant aspects' are those factual
    elements which determine whether reasoned analogy supports, or
    demands, a like result.").       Material distinctions between the two
    sets of circumstances increase the danger that any such inference
    would amount to no more than mere speculation, and the district
    court bears the responsibility of separating the wheat from the
    chaff.   See Morales Feliciano v. Rullán, 
    378 F.3d 42
    , 58 (1st Cir.
    2004); Conward, 
    171 F.3d at 20-21
    .
    Here, we discern no abuse of discretion in the district
    court's application of these tenets.          Cf. Freeman v. Package Mach.
    Co., 
    865 F.2d 1331
    , 1340 (1st Cir. 1988) ("Only rarely — and in
    extraordinarily compelling circumstances — will we, from the vista
    of a cold appellate record, reverse a district court's on-the-spot
    - 13 -
    judgment concerning the relative weighing of probative value and
    unfair effect.").         Although the Credit Union's motion in limine
    sought to exclude evidence regarding seven possible comparators,
    its objection at trial came in response to Daumont's attempt to
    introduce evidence regarding Dalitza Caez, a teller-supervisor.
    After banning the introduction of evidence as to Caez, the district
    court indicated that it would exclude evidence of the other
    proposed comparators on essentially the same grounds.                See Daumont
    I, 
    2019 WL 8808083
    , at *1.               Even so, the only other specific
    comparator evidence that Daumont later offered at trial concerned
    Carlos Vazquez, a branch manager.
    In     this    venue,   Daumont     focuses      exclusively    on   the
    exclusion of evidence relating to Caez and Vazquez.                       She has,
    therefore, waived any argument that the district court should have
    allowed her to adduce evidence as to comparators other than Caez
    and Vasquez.      See United States v. Zannino, 
    895 F.2d 1
    , 17 (1st
    Cir.   1990)     ("[I]ssues     adverted      to   in   a   perfunctory    manner,
    unaccompanied     by     some   effort   at    developed     argumentation,     are
    deemed waived.").
    In     excluding      testimony     regarding      Caez   —    who   was
    suspended for thirty days and demoted to teller after an incident
    in which she cashed a check for her mother — the court highlighted
    two    primary    distinctions      between        Caez's    circumstances      and
    Daumont's circumstances.           First, Caez did not hold a "senior
    - 14 -
    position" comparable to Daumont's position as a branch manager.
    Daumont I, 
    2019 WL 8808083
    , at *2.       Second, Caez did not commit
    misconduct as serious as signing another person's name to an
    official Credit Union document.      See 
    id.
       Moreover, Daumont was
    (by her own admission) seven times a repeat offender, while Caez
    was not shown to have engaged in more than one isolated act of
    misconduct.    Last — but far from least — the rule of conduct that
    Daumont violated specified dismissal as the penalty for a first
    offense; in contrast, Caez violated a rule that called only for
    progressive discipline, starting with warnings.
    These differences are consequential and, taken together,
    undercut Daumont's argument that comparator evidence concerning
    Caez's   troubles    should   have   been   allowed   into   evidence.
    Distinctions as to an employee's position and as to the severity
    or frequency of her misconduct are proper factors in determining
    that a plaintiff and a proposed comparator are not similarly
    situated.    See, e.g., Murray v. Kindred Nursing Ctrs. W. LLC, 
    789 F.3d 20
    , 27 (1st Cir. 2015); Woodward v. Emulex Corp., 
    714 F.3d 632
    , 636 (1st Cir. 2013).
    In an effort to blunt the force of this reasoning,
    Daumont argues that the Credit Union's stated policy of applying
    its disciplinary rules uniformly to all employees renders their
    relative job classifications irrelevant. We agree with the premise
    of Daumont's argument:    an employer's policies can be germane to
    - 15 -
    the analysis of comparator evidence.            See Murray, 789 F.3d at 28.
    We disagree, though, with the conclusion that Daumont would have
    us draw.          She has cited no authority for the much different
    proposition that the Credit Union's policy somehow compelled the
    court       to   disregard   employees'     roles   and   responsibilities   in
    determining if those employees were similarly situated "in all
    relevant aspects."           Dartmouth Rev., 
    889 F.2d at 19
    .            In the
    circumstances of this case, we think it well within the district
    court's discretion to have considered the differences between
    Daumont's position and the comparators' positions.                 See, e.g.,
    Cardona Jiménez v. Bancomercio de P.R., 
    174 F.3d 36
    , 42 & n.4 (1st
    Cir. 1999).
    Daumont's   attempt   to   introduce     comparator   evidence
    concerning Vazquez fares no better.             At trial, the district court
    rejected this proffer, finding that Daumont did not establish that
    Vazquez had engaged in comparable misconduct.                   On its face,
    Vasquez's misconduct appears to be a far cry from Daumont's:                 he
    abandoned his post at one Credit Union branch and traveled to
    another branch, where he instructed a security guard, without rhyme
    or reason, to forbid the public from entering.2                  Although the
    Credit Union's disciplinary letter informed Vasquez that he could
    2
    This bizarre incident apparently occurred in connection with
    a larger dispute over the internal governance of the Credit Union.
    The details of that larger dispute are lost in the mists of time.
    - 16 -
    have been terminated (and would be if his behavior was repeated),
    he was only suspended for one week.
    Excluding this evidence was within the district court's
    discretion. Although the Credit Union's rules of conduct delineate
    a   scheme    of    progressive   discipline,      they   prescribe     immediate
    termination for particularly serious infractions.              Whereas Daumont
    had violated the Credit Union's rules relating to the provision of
    false information on official documents (the stated penalty for
    which   was    dismissal,     even    for   a    first    offense),     Vasquez's
    transgressions (such as exhibiting a lack of courtesy and inducing
    misconduct on the part of other employees) were first offenses for
    which the rules specified either verbal or written warnings.                   In
    sum, the probative value of this evidence was slight and was
    outweighed by the likelihood that it would sow the seeds for
    conjecture.        See Freeman, 
    865 F.2d at 1340
    .
    We add a coda.      While Daumont complains that, overall,
    the district court failed to weigh the "comparative seriousness"
    of other employees' misconduct against her own, we have held that
    "[n]o valid comparison can be drawn between two incidents for the
    purpose of proving disparate treatment if 'differentiating or
    mitigating      circumstances'       distinguish     either    the     employee's
    conduct or the employer's response to it."               Murray, 789 F.3d at 27
    (quoting Conward, 
    171 F.3d at 21
    ).              So it is here:       the district
    court supportably concluded that the Credit Union was interpreting
    - 17 -
    its own policy according to the tenor of that policy.           See Daumont
    I, 
    2019 WL 8808083
    , at *2.     The burden was on Daumont to establish
    the   material   equivalence   of    the     comparators'   misconduct,   see
    Perkins, 
    78 F.3d at 751
    , and she failed to carry that burden.3
    The bottom line is that "[a] district court is accorded
    a wide discretion in determining the admissibility of evidence."
    Sprint/United Mgmt. Co. v. Mendelsohn, 
    552 U.S. 379
    , 384 (2008)
    (quoting United States v. Abel, 
    469 U.S. 45
    , 54 (1984)).              Here,
    the court acted within the compass of that discretion in concluding
    that "[a]pples and apples [were] not being compared."            Daumont I,
    
    2019 WL 8808083
    , at *2.
    C.   Judgment as a Matter of Law.
    We next examine Daumont's substantive assignments of
    error regarding the district court's entry of judgment as a matter
    of law.     Even without the excluded comparator evidence, Daumont
    says, the district court should have allowed her claims to go to
    the jury.    The challenged ruling engenders de novo review.              See
    Downey, 
    633 F.3d at 9
    .     Such review requires us to take the facts
    "and the inferences reasonably extractable therefrom in the light
    most hospitable to the nonmovant."            Martínez-Serrano v. Quality
    3We note — as did the district court, Daumont I, 
    2019 WL 8808083
    , at *1 & n.2 — that Daumont's opposition to the Credit
    Union's motion in limine was virtually bereft of factually specific
    arguments as to how "each of the proposed employees' circumstances"
    compared to her own, leaving evidentiary gaps that she did not
    fill when the Credit Union objected to her proffers at trial.

    In performing this tamisage, we cannot "pass upon the credibility
    of the witnesses, resolve evidentiary conflicts, or engage in a
    comparative weighing of the proof."          
    Id. at 285
    .    When all is said
    and done, judgment as a matter of law is appropriate only when the
    record dictates "a result as to which reasonable minds could not
    differ."   
    Id.
    On appeal, Daumont submits that the court below should
    have allowed three distinct causes of action to go to the jury.
    We examine those three causes of action in sequence.
    1.   The ADEA Claim.     To prevail on a claim of wrongful
    discharge under the ADEA, an employee must carry the burden of
    proving "that [she] would not have been fired but for [her] age."
    Dávila v. Corporación de P.R. Para La Difusión Pública, 
    498 F.3d 9
    , 15 (1st Cir. 2007) (quoting Mesnick v. Gen. Elec. Co., 
    950 F.2d 816
    , 823 (1st Cir. 1991)).      In the absence of direct evidence of
    discriminatory animus — and none has been tendered here — an
    employer's    discriminatory   motive        may   be   established   through
    circumstantial evidence.     See Acevedo-Parrilla v. Novartis Ex-Lax,
    Inc., 
    696 F.3d 128
    , 138 (1st Cir. 2012).                 Taking that route
    requires resort to the McDonnell Douglas framework.            See McDonnell
    Douglas Corp. v. Green, 
    411 U.S. 792
    , 802-05 (1973); see also Soto-
    Feliciano v. Villa Cofresí Hotels, Inc., 
    779 F.3d 19
    , 22-23 (1st
    Cir. 2015); Mesnick, 
    950 F.2d at 823
    .
    - 19 -
    At the first stage of the framework, the plaintiff must
    set forth her prima facie case.       See Mesnick, 
    950 F.2d at 823
    .          In
    this instance, that required Daumont to show "1) [she] was at least
    40 years old at the time [she] was fired; 2) [she] was qualified
    for the position [she] had held; 3) [she] was fired, and 4) the
    employer    subsequently    filled    the    position,      demonstrating     a
    continuing need for the plaintiff's services."             Vélez, 
    585 F.3d at 447
    .   Even though this is a "modest" showing, 
    id.
     (quoting Rathbun
    v. Autozone, Inc., 
    361 F.3d 62
    , 71 (1st Cir. 2004)), it suffices
    to create a rebuttable presumption that the adverse employment
    action was motivated by age-based discrimination.
    To   rebut   this   presumption,      the    employer   must   then
    proffer a legitimate, nondiscriminatory rationale for having taken
    the adverse employment action.             See Dávila, 
    498 F.3d at 16
    ;
    Mesnick, 
    950 F.2d at 823
    .       This stage of the analysis is not meant
    to shift the burden of proof but, rather, is intended merely to
    impose a burden of production.        See Sanchez v. P.R. Oil Co., 
    37 F.3d 712
    , 720 (1st Cir. 1994).
    At the third and final stage of the McDonnell Douglas
    framework, the employee must "prove by a preponderance of the
    evidence that the legitimate reason[] offered" in the employer's
    defense was "not its true reason[], but w[as] a pretext for
    discrimination."     Vélez, 
    585 F.3d at 447-48
     (quoting Reeves v.
    Sanderson   Plumbing     Prods.,   Inc.,    
    530 U.S. 133
    ,   143   (2000)).
    - 20 -
    Because the presumption of discrimination has vanished at this
    stage, see Dávila, 
    498 F.3d at 16
    , the employee "must 'elucidate
    specific facts which would enable a jury to find that the reason
    given is not only a sham, but a sham intended to cover up the
    employer's real motive:         age discrimination,'" Soto-Feliciano, 779
    F.3d at 25 (quoting Mesnick, 
    950 F.2d at 824
    ).
    In granting the Credit Union's motion for judgment as a
    matter of law, the district court determined that "[a]bsolutely no
    evidence (neither direct or circumstantial) was presented that
    would    enable    a     jury   to   conclude   or    reasonably   infer   that
    Defendants’ actions were carried out because of [Daumont]’s age."
    Daumont   II,     
    2019 WL 8809765
    ,   at   *2.     Elaborating   on   this
    conclusion, the court noted that Daumont had stipulated to signing
    Tirado's name to withdrawal slips on at least eight occasions;
    that those actions clearly violated the Credit Union's rules of
    conduct; that the rules of conduct prescribed termination of
    employment as the penalty for even a single infraction; and that
    Daumont had introduced no evidence from which a reasonable jury
    could conclude that the Credit Union's response to Daumont's
    misconduct was either unreasonable or at odds with its usual
    practice.   See 
    id. at *3
    .
    Before us, Daumont complains that the district court
    failed to draw reasonable inferences from the evidence in her
    favor.    The record, though, belies this plaint.              It shows with
    - 21 -
    conspicuous    clarity   that    the    court    correctly    focused    on   the
    ultimate issue of age discrimination.             See 
    id. at *2-4
    .      Daumont
    bore the burden of establishing that age discrimination was the
    but-for cause of her discharge.            See Gross v. FBL Fin. Servs.,
    Inc., 
    557 U.S. 167
    , 177 (2009).            She attempted to satisfy this
    burden by showing that the Credit Union's stated reason for
    cashiering her was pretextual, but a demonstration of pretext
    demands something more than existential doubt or an error of
    judgment on the employer's part.               See Murray, 789 F.3d at 27;
    Mesnick, 
    950 F.2d at 825
    .        And none of the evidence in this record
    was capable of grounding a reasonable inference that the Credit
    Union did not believe Daumont had violated its rules and terminated
    her for that reason.
    To illustrate, Lourdes Rodriguez, the Credit Union's
    human    resources   director,    testified      that   an   employee    signing
    another person's name on a withdrawal slip was unacceptable to the
    Credit Union and that such conduct violated the rule prohibiting
    the falsification of official documents.                She also pointed out
    that the rules prescribed termination of employment as the penalty
    for even a first offense.          Tellingly, Rodriguez's testimony in
    these particulars was both uncontradicted and unimpeached.
    Daumont tries to parry this thrust by pointing to the
    Credit    Union's    treatment   of    Santos    (the   teller   who    actually
    effectuated the February 20 withdrawal).           Santos testified that he
    - 22 -
    received only a written reprimand for his role in the incident.
    Even so, Daumont's claim of disparate treatment is more cry than
    wool:    given Santos's subordinate relationship to Daumont, the
    fact that he did not sign Tirado's name on the slip, and the fact
    that    Daumont   had   signed     Tirado's    name   on    several   previous
    occasions, he and Daumont were not fair congeners.                 See, e.g.,
    Cardona Jiménez, 
    174 F.3d at 42
    ; Dartmouth Rev., 
    889 F.2d at 20
    .
    It follows that the evidence as to the manner in which the Credit
    Union disciplined Santos cannot support a reasonable inference of
    discrimination vis-à-vis Daumont.
    By the same token, the record does not contain any basis
    for a claim in the nature of an estoppel.             Contrary to Daumont's
    insinuations, there is simply no evidence to suggest that either
    Adorno or Hilerio authorized the earlier transactions in which
    Daumont signed Tirado's name.           Indeed, nothing in the record
    supports an inference that Daumont's superiors were aware of the
    provenance of those transactions at any time before the Credit
    Union    commenced      its    investigation     into      the   February   20
    transaction.
    Finally, Daumont argues that the cause of her firing
    could not have been the February 20 transaction, since both Tirado
    and Santos testified that the Credit Union did not speak to them
    about the transaction before Hilerio made the decision to terminate
    Daumont's employment.         But Daumont is aiming at the wrong target:
    - 23 -
    she identifies no new facts that either of these individuals could
    have   contributed,      which     might      have    changed     the    decisional
    calculus.         Importantly,     the     Credit     Union     never    challenged
    Daumont's statement that Tirado had verbally authorized her to
    make the withdrawals; instead, it based her discharge on the fact
    — stipulated to by Daumont — that Daumont signed another person's
    (Tirado's) name to an official document.
    The short of it is that Daumont — in order to survive
    summary judgment — needed to adduce "minimally sufficient evidence
    to permit a reasonable [jury] to conclude that [she] was fired
    because of [her] age."            Dávila, 
    498 F.3d at 16
    .           Although she
    attempted    to    do   so   by    suggesting        that   the   Credit    Union's
    explanation for her discharge was pretextual, "[m]ere questions
    regarding the employer's business judgment are insufficient to
    raise a triable issue as to pretext."                Acevedo-Parrilla, 696 F.3d
    at 140.     As we have said, "[w]hether a termination decision was
    wise or done in haste is irrelevant, so long as the decision was
    not made with discriminatory animus."                   Rivera–Aponte v. Rest.
    Metropol No. 3, Inc., 
    338 F.3d 9
    , 11 (1st Cir. 2003).                    Without any
    evidence that the Credit Union did not believe in good faith that
    Daumont's act of signing Tirado's name to a withdrawal slip
    constituted    falsification        of   an    official       document    and   thus
    warranted termination — and there is no such evidence in this
    record — "it is not our province to second-guess [its] decision."
    - 24 -
    Dávila, 
    498 F.3d at 17
    .     Consequently, the district court did not
    err in granting the Credit Union's motion for judgment as a matter
    of law on Daumont's ADEA claim.
    2.   The Law 100 Claim.       Daumont also pursued an age
    discrimination claim under Puerto Rico's employment discrimination
    statute, colloquially known as "Law 100."       See 
    P.R. Laws Ann. tit. 29, § 146
    . On this claim, too, the district court granted judgment
    as a matter of law in favor of the Credit Union.       See Daumont II,
    
    2019 WL 8809765
    , at *4.
    We need not tarry.       Although Law 100 brings to bear a
    burden-shifting framework different from that applicable to the
    ADEA, the two statutes are coextensive with respect to the ultimate
    question of discrimination.      See Rivera-Rivera v. Medina & Medina,
    Inc., 
    898 F.3d 77
    , 97 (1st Cir. 2018); Dávila, 
    498 F.3d at 18
    .
    Because we already have determined that Daumont did not adduce
    evidence from which a jury could reasonably infer that she was
    discharged because of her age, see supra Part II(C)(1), her appeal
    of the adverse judgment on her Law 100 claim necessarily fails.
    3.   The Law 80 Claim.    This leaves Daumont's claim under
    Puerto Rico's wrongful discharge statute, colloquially known as
    "Law 80."   See P.R. Laws Ann. tit. 29, § 185a.     The district court
    disposed of this claim by granting judgment as a matter of law in
    the Credit Union's favor, see Daumont II, 
    2019 WL 8809765
    , at *5,
    and Daumont assigns error.
    - 25 -
    Law   80   provides   for    damages      when   an   employee   is
    discharged without "just cause," which is defined as "such reasons
    that affect the proper and regular operations of an establishment."
    P.R. Laws Ann. tit. 29, § 185b.              Helpfully, the statute lists
    several   specific    examples   of   just    cause,   including   "repeated
    violations of the reasonable rules and regulations established for
    the operation of the establishment."4          Id.
    Under Law 80's burden-shifting framework, an employee
    must allege not only that her employment was terminated but also
    that the termination was unjustified.          See Pérez v. Horizon Lines,
    Inc., 
    804 F.3d 1
    , 9 (1st Cir. 2015).            In response, the employer
    bears the burden of showing "that it had a reasonable basis to
    believe that an employee has engaged in one of those actions that
    the law identifies as establishing [just] cause."            
    Id.
       To prevail
    at that juncture, the employee must rebut the showing of just cause
    with "probative evidence that [the employer] did not genuinely
    believe in or did not in fact terminate [the employee] for the
    reason given."   
    Id. at 11
    .
    4 This exemplar is coupled with a proviso designed to ensure
    that the employee was on notice of the rules of conduct.        See
    § 185b.   Here, however, the record reflects no genuine issue
    regarding Daumont's awareness of the Credit Union's rules. Indeed,
    the Credit Union introduced into evidence a 2012 letter, which
    indicated that Daumont not only knew of the rules but that she had
    been reprimanded under them for her role in a transaction involving
    her daughter and put on notice of the potential consequences of
    future misconduct.

    In the case at hand, the record makes manifest that the
    Credit Union had a sound basis to believe that Daumont had engaged
    in misconduct sufficient, on its face, to establish just cause.
    After all, Daumont was discharged because she admittedly (and
    repeatedly)    engaged    in   conduct      that    directly   violated    the
    employer's rules.      So, too, the record is pellucid that, under the
    rules, even a first offense for such a violation was a fireable
    offense.    To cinch the matter, Daumont offered nothing in the way
    of probative evidence adequate to show that the Credit Union did
    not discharge her based on her misconduct.               On these facts, we
    agree with the district court that a reasonable jury could only
    conclude that the Credit Union had established just cause for
    terminating Daumont's employment. See Daumont II, 
    2019 WL 8809765
    ,
    at *5; see also Pérez, 804 F.3d at 10 (explaining that, under Law
    80,   a   "perceived   violation   suffices        to   establish   that   [the
    employer] did not terminate [the employee] on a whim, but rather
    for a sensible business-related reason" (emphasis and alterations
    in original) (quoting Hoyos v. Telecorp Commc'ns, Inc., 
    488 F.3d 1
    , 10 (1st Cir. 2007))). We conclude, therefore, that the district
    court appropriately granted judgment as a matter of law in favor
    of the Credit Union on Daumont's Law 80 claim.

    III. CONCLUSION
    We need go no further. For the reasons elucidated above,
    the judgment of the district court is
    Affirmed.
