    Overview
    Meet Roger Boncy and Joseph Baptiste.         Boncy once served
    as chairman and CEO of a U.S.-based investment company called Haiti
    Invest, LLC.     And Baptiste once sat on that company's board of
    directors.    We use the past tense, because everything changed when
    the feds accused them of conspiring to bribe Haitian officials
    into approving an $84 million port project in that country — one
    involving cement factories, a shipping-vessel repair station, an
    international transshipment station, and a power plant (among
    other things). Prosecutors tried them jointly. And each had their
    own lawyer.     We will save lots of details about the trial and its
    aftermath for later.       But for now it is enough to note the
    following.
    The     government   claimed    (based   in    large   part   on
    undercover recordings played at trial) that Baptiste and Boncy
    solicited money from undercover agents (posing as investors in
    Haitian infrastructure ventures), which they promised to funnel to
    Haitian bureaucrats through a Baptiste-controlled nonprofit that
    supposedly helped Haiti's poor — 5% of project costs would be
    allocated to bribe Haitian authorities.       And as a further way to
    grease the project's skids, the duo — again according to the
    government's theory — promised to pay off Haitian officials with
    - 3 -
    campaign contributions, offers of future jobs, and money to fund
    their favorite social programs.                 At the trial's end, the jury
    convicted        them   of   conspiring    to   violate    the    Foreign   Corrupt
    Practices Act and the Travel Act (count 1), and convicted Baptiste
    (but       not   Boncy)   of   violating   the    Travel    Act    (count   2)   and
    conspiring to violate the Money Laundering Act (count 3).1
    After firing his original attorney and hiring a new
    lawyer, Baptiste moved under Criminal Rule 33 for a new trial on
    the counts of conviction based on (according to the motion)
    ineffective assistance of counsel under the Sixth Amendment.2
    Simplified somewhat, and as relevant here:
    1                                               the Foreign
    Corrupt Practices Act criminalizes bribing foreign officials, see
    15 U.S.C. § 78dd-2(a); the Travel Act criminalizes traveling in
    "foreign commerce" with an intent to commit an "unlawful activity,"
    see 18 U.S.C. § 1952(a)(3); and the Money Laundering Act
    criminalizes transferring funds from the United States to another
    country with the intent to bribe a foreign official, see 18 U.S.C.
    § 1956(a)(2)(A).
    2   Rule 33 reads in full:
    (a) Defendant's Motion. Upon the defendant's
    motion, the court may vacate any judgment and
    grant a new trial if the interest of justice
    so requires. If the case was tried without a
    jury, the court may take additional testimony
    and enter a new judgment.
    (b) Time to File.
    (1) Newly Discovered Evidence. Any motion for
    a new trial grounded on newly discovered
    evidence must be filed within 3 years after
    the verdict or finding of guilty. If an appeal
    is pending, the court may not grant a motion
    - 4 -
    Likewise invoking Criminal Rule 33, Boncy asked for a separate new
    trial on the count of conviction because (the motion argued)
    Baptiste's lawyer's "ineffective[ness]" influenced how the jury
    "view[ed] . . . both defendants" and so impaired his (Boncy's)
    Fifth Amendment "due process right" to a "fair" proceeding.               The
    government opposed both motions.
    Following an evidentiary hearing, the district judge
    found that Baptiste had shown deficient performance of counsel and
    that the cumulative effect of counsel's deficiencies caused him
    (Baptiste) prejudice.       Not only that, but the judge also found
    Baptiste's attorney's shortcomings prejudiced Boncy by (among
    other things) requiring "Boncy's counsel . . . to play an outsized
    role at trial rather than pursue his preferred defense strategy."
    And   noting   that   a   joint   trial   of   alleged   coconspirators   is
    presumptively     appropriate      and    that    "severance    [was]     not
    warranted," the judge ordered a joint retrial in the interest of
    "justice" because neither defendant got "a fair" first trial — the
    for a new trial until the appellate court
    remands the case.
    (2) Other Grounds. Any motion for a new trial
    grounded on any reason other than newly
    discovered evidence must be filed within 14
    days after the verdict or finding of guilty.
    See Fed. R. Crim. P. 33 (emphasis added).

    significance of the "justice" buzzword (pulled from Rule 33) will
    be apparent later.
    From that decision, the government now appeals.             After
    setting out the guiding legal principles, we turn directly to the
    issues that confront us — adding additional details necessary to
    put matters into workable perspective.        When all is said and done,
    we affirm.
    Guiding Legal Principles
    Judges can grant a new trial if required in "the interest
    of justice," see Fed. R. Crim. P. 33(a) — though they should grant
    these   motions   only    "sparingly"   and   to   prevent   "a    perceived
    miscarriage of justice," see United States v. Veloz, 
    948 F.3d 418
    ,
    437 (1st Cir. 2020) (quoting United States v. Gramins, 
    939 F.3d 429
    , 444 (2d Cir. 2019)).       Applying abuse-of-discretion review,
    United States v. Gonzalez, 
    949 F.3d 30
    , 34 (1st Cir.), cert.
    denied, 
    141 S. Ct. 327
     (2020), we can affirm a judge's new-trial
    decision even if "there was sufficient evidence to convict," United
    States v. Rothrock, 
    806 F.2d 318
    , 322 (1st Cir. 1986).            This review
    standard is multifaceted, requiring us to inspect "fact findings
    for clear error, legal issues de novo (in nonlegalese, with fresh
    eyes), and judgment calls with some deference."         United States v.
    McCullock, 
    991 F.3d 313
    , 317 (1st Cir. 2021).         Showing an abuse of
    discretion is especially difficult when, "as here, the judge who
    - 6 -
    hear[d]" the new-trial motions "is the same judge who presided
    over the trial," because in that scenario, "substantial deference
    is due to the judge's perceptions."          See Gonzalez, 949 F.3d at 34
    (emphasis added).    And we ultimately will reverse "only when left
    with a definite conviction that 'no reasonable person could agree
    with the judge's decision,'"         see    McCullock, 991 F.3d         at 317
    (quoting United States v. Cruz-Ramos, 
    987 F.3d 27
    , 41 (1st Cir.
    2021)) — a rule that stops us from switching our discretion for
    the judge's, see Rothrock, 
    806 F.2d at 321-22
    .               But at the same
    time (and as the government is quick to note), a material error of
    law is never discretionary and so always is an abuse of discretion.
    See Gonzalez, 949 F.3d at 34.
    To grant a new trial on an ineffective-assistance claim,
    a judge must find that counsel performed objectively unreasonably
    and that prejudice followed.       See, e.g., United States v. Silvia,
    
    953 F.3d 139
    , 142 (1st Cir. 2020). Deficient performance "requires
    showing that counsel made errors so serious that [he] was not
    functioning as the 'counsel' guaranteed the defendant by the Sixth
    Amendment."    Strickland v. Washington, 
    466 U.S. 668
    , 687 (1984).
    And   deficient   performance     prejudices     the   defense   when   it   is
    reasonably    probable   "that,    but     for   counsel's    unprofessional
    errors, the result of the proceeding would have been different" —
    i.e., "a probability sufficient to undermine confidence" in the
    - 7 -
    result.   
    Id. at 694
    .   The probability "of a different result must
    be substantial, not just conceivable."      Harrington v. Richter, 
    562 U.S. 86
    , 112 (2011).     But that does not require a showing that
    counsel's actions "more likely than not altered the outcome."
    Strickland, 
    466 U.S. at 693
     (emphasis added); see also Williams v.
    Taylor, 
    529 U.S. 362
    , 405-06 (2000) (stating that this standard is
    a lesser showing than a preponderance of the evidence).           And when
    assessing prejudice, a judge "must consider the totality of the
    evidence before the . . . jury," because "a verdict . . . only
    weakly supported by the record is more likely to have been affected
    by errors than one with overwhelming record support," Strickland,
    
    466 U.S. at 695-96
     — though we judges must never forget that the
    purpose of the prejudice prong is to ensure a defendant has not
    suffered a fundamentally unfair or unreliable outcome, see 
    id. at 687
    .
    Arguments and Analysis
    The   government   does   not   quarrel   with   the   judge's
    deficient-performance findings — findings premised on a long list
    of failures on Baptiste's lawyer's part (we hit the highlights,
    quoting from the judge's decision):
    •    He could not "open discovery produced by the [g]overnment."
    •    He "did not provide copies of documents or audio and video
    recordings to . . . Baptiste, nor did they ever sit down
    - 8 -
    together to review all of the materials that the [g]overnment
    had provided."
    •   He did not "'thoroughly review' certain documents."
    •   "[H]e [did] not investigate[]" the case "sufficiently to
    understand the import" of the government's evidence or to
    craft an appropriate response.
    •   He   did   not   get   English    translations    of       Haitian-Creole
    recordings, even after learning about "potential errors" in
    one of the government's translations.
    •   He "did not subpoena any witness" or "formulate his own list
    of   potential   witnesses   in    support   of   .    .    .   Baptiste's
    potential defenses."
    •   "[H]e did not . . . identify or contact any expert witnesses
    that could have provided evidence on Haitian law or business
    practices."
    •   He "continued to pursue an entrapment defense," even though
    "others had previously told him that the defense was not
    available to . . . Baptiste on the facts of the case" — a
    mistake that essentially put Baptiste in the thick of the
    conspiracy. 3
    3Consider this snippet from Baptiste's lawyer's opening
    statement:
    - 9 -
    [T]he FBI undercover agents . . . were
    predisposed, predisposed to thinking that the
    only way to invest successfully in Haiti was
    to commit a bribe. The FBI agents fixated on
    the concept of pay-to-play [and] sought to
    manufacture a crime and criminals out of men
    who had impeccably, impeccably clean records.
    Remember, the FBI agents solicited . . .
    Baptiste and . . . Boncy to travel to Boston,
    and they came here on their own dime. They
    solicited them to travel to Boston to receive
    the FBI's pitch for them to engage in criminal
    activity.
    In short, the FBI did not care about
    benefiting Haiti or having a profitable
    investment. What the FBI hoped for, what they
    had hoped for was for corruption to occur.
    Conversely, . . . Baptiste and . . . Boncy
    sought to operate legally while bringing
    foreign direct investment into Haiti that
    would benefit the people of Haiti.
    What you have going on in all of this
    fake investment talk is the undercover agents
    repeatedly asking whether Haiti is pay-to-
    play, a pay-to-play country.
    . . .
    While you are carefully listening to the
    government's evidence, ask yourself how many
    times does the government need to be told by
    an American citizen that he will not commit a
    crime before the government leaves him alone
    and goes away but continues to attempt to
    manufacture a new criminal and a new crime.
    Testifying at the hearing on the new-trial motions, Baptiste's
    attorney admitted raising the entrapment theory even though other
    "people" told him he "didn't have the elements to establish that
    defense.
    - 10 -
    •   He   "only    cross-examined      two       of        the   [g]overnment's      six
    witnesses, none of whom [he] had contacted or sought to
    interview prior to trial."
    •   He "elicited damaging testimony" from the two he did cross.
    •   And he deferred to Boncy's lawyer on the "cross-examinations
    of   the    remaining    witnesses,"        even       though     Boncy's    "trial
    strategy was to portray . . . Baptiste as the primary driver
    of   the    alleged   conspiracy"       —    a    conspiracy       that     Boncy's
    attorney insisted Boncy was not a part of.
    But while the government makes no argument against the deficient-
    performance finding, the arguments it does present do not persuade
    us to reverse.
    A.
    The    government    starts      off       by    insisting     that    "[t]he
    evidence    of    Baptiste's    and   Boncy's          guilt      was   overwhelming,"
    claiming that "[i]n call after recorded call" they "agreed to bribe
    Haitian officials" to grease the skids for the project.                              And
    according to the government, the evidence underpinning "Baptiste's
    convictions for violating the Travel Act and conspiring to commit
    money laundering was no less compelling."                         Yet the judge never
    "addressed the weight of this evidence" — or so the government
    - 11 -
    continues, with a nod to Strickland — and thus "erred as a matter
    of law."     We see several problems with this argument, however.
    First      off,   the    government's         thesis      suggests      that
    sufficiently strong evidence can sink any ineffective-assistance
    claim.     No one denies that the strength of the prosecution's case
    is a factor in the prejudice analysis.                      See Turner v. United
    States, 
    699 F.3d 578
    , 584 (1st Cir. 2012).                   But it is not the be-
    all and end-all, for (after all) the chief "focus" remains "on the
    'fundamental fairness of the proceeding.'"                   See Dugas v. Coplan,
    
    506 F.3d 1
    ,    9    (1st   Cir.   2007)      (emphasis       added      and   quoting
    Strickland, 
    466 U.S. at 696
    ).                To put it in slightly different
    terms,   the      prejudice     probe     is    not      designed      to   be    applied
    "mechanical[ly]"        —   because     "when        a   court   is    evaluating      an
    ineffective-assistance           claim,        the       ultimate      inquiry       must
    concentrate on 'the fundamental fairness of the proceeding.'"
    Weaver v. Massachusetts, 
    137 S. Ct. 1899
    , 1911 (2017) (quoting
    Strickland,       
    466 U.S. at 696
    ).      And      while   the    government    is
    convinced of Baptiste's and Boncy's guilt based on its own —
    basically unchallenged — evidence, "we have never intimated that
    the right to counsel is conditioned upon actual innocence," because
    actually "[t]he constitutional rights of criminal defendants are
    granted to the innocent and the guilty alike."                      See Kimmelman v.
    Morrison, 
    477 U.S. 365
    , 380 (1986).                  "The prejudice essential to
    - 12 -
    a violation of the Sixth Amendment right to effective assistance
    of counsel is not being convicted though one is innocent, although
    that is the worst kind," we explained recently, echoing a sibling
    circuit   —    "it   is   being   convicted   when   one    would   have   been
    acquitted, or at least would have had a good shot at acquittal,
    had one been competently represented."         United States v. Mercedes-
    De La Cruz, 
    787 F.3d 61
    , 67 n.6 (1st Cir. 2015) (quotations omitted
    and quoting Owens v. United States, 
    387 F.3d 607
    , 610 (7th Cir.
    2004) (per Posner, J.)).        And in the context of a new-trial motion,
    courts recognize that Rule 33's standard "is the interest of
    justice" — a standard that "comprehends the interests of the law-
    abiding as well as those of possibly guilty defendants."                    See
    United States v. Morales, 
    902 F.2d 604
    , 609 (7th Cir. 1990) (per
    Posner, J.).
    Quoting Strickland, the government's papers below also
    spent a lot of time emphasizing how the judge had to — but did not
    — "consider the 'totality of the evidence' at trial because errors
    are   less     likely     to   create   prejudice    when    a   verdict   has
    'overwhelming record support.'"         But with the government's having
    put this all front and center before the judge, we think it fair
    to infer that she considered and rejected the government's points
    — rather than ignoring them.            See generally United States v.
    Jimenez-Beltre, 
    440 F.3d 514
    , 519 (1st Cir. 2006) (en banc) (noting
    - 13 -
    that we can conclude that the judge analyzed a defendant's claim
    "by comparing what was argued by the parties . . . with what the
    judge did").    And as for the government's "overwhelming evidence"
    refrain, we need only point out again that a judge can grant a new
    trial under Rule 33 to prevent "a miscarriage of justice" — even
    if "there [is] sufficient evidence to convict."        See Rothrock, 
    806 F.2d at 322
    .
    On top of all that, we "presume" — per Supreme Court
    directive — that judges "know" and correctly "apply" the law "in
    making their decisions."       Walton v. Arizona, 
    497 U.S. 639
    , 653
    (1990), overruled on other grounds by Ring v. Arizona, 
    536 U.S. 584
     (2002).     So we presume the judge considered the totality of
    the evidence as required, particularly since the government offers
    no persuasive reason not to apply that presumption here.
    B.
    The    government     next    faults   the   judge   for   not
    "consider[ing]" Baptiste's counsel's failings "in light of Boncy's
    complementary defense."       Boncy's lawyer, the government writes,
    "took the lead on cross-examining witnesses and, through his
    skilled questioning, advanced an argument" that no "conspiratorial
    agreement" ever existed — which matters because Baptiste could not
    - 14 -
    be convicted of any conspiracy without a coconspirator.                      The
    government, however, cannot win under this theory either.
    Hurting   the   government    here    is    that    other   supposed
    coconspirators   existed,   albeit     unindicted      ones   (as     even   the
    government concedes). Putting that point aside does the government
    no good, however.     Even granting that Boncy's lawyer tried on
    cross-examination   to    play   up   the   no-conspiratorial-agreement
    angle, the government is still stuck with the judge's finding —
    based mostly on Baptiste's counsel's evidentiary-hearing testimony
    — that the two defense teams "did not 'coordinate' . . . or see
    'eye to eye'" on "their defense strategy."           And the judge so found
    because Boncy's attorney had "'his direction'" and Baptiste's
    attorney had his own "'in terms of how [they] were proceeding with
    the trial'" (the internal quotations are from Baptiste's counsel's
    testimony at the new-trial motion hearing, by the way).
    This finding does not rest on thin air either — for the
    record shows that Boncy's counsel spent much energy trying make
    Baptiste the real culprit in this conspiracy while distancing Boncy
    from   Baptiste's   deception.        Boncy's    lawyer,       for    example,
    emphasized recordings in which Baptiste — not Boncy — was "[t]he
    person who's talking about . . . how" bribery is "done in Haiti."
    And Boncy's attorney suggested that Baptiste — not Boncy —"raised"
    the bribery idea by demanding that "something had to be put on the
    - 15 -
    table" for bribes (that "something" according to the government,
    being payola). More, Boncy's counsel accused Baptiste of "chiding"
    Boncy about Boncy's "unwillingness to put money on the table" for
    bribes.    More still, Boncy's lawyer elicited agent testimony that
    Baptiste and Boncy said "two different things" about the "pay-
    offs" to Haitian officials — Baptiste, according to the agent, was
    talking about "pay-offs" while Boncy was not.         Boncy's counsel did
    all this while also painting Boncy (himself a lawyer) as "very
    strict" on compliance issues compared to Baptiste. And more still,
    Boncy's lawyer alternatively suggested that Baptiste was trying to
    "hustle[]" some money from the feds — that Baptiste wanted "5
    percent"   built   into   the   project   cost   (a   key   part   of   the
    government's conspiracy theory; recall our "overview" remarks at
    the opinion's beginning) simply to enrich himself rather than to
    buy off Haitian politicos. Boncy's attorney returned to this theme
    during closing arguments, calling Baptiste a liar who told the
    undercover agents what they "wanted to hear . . . to keep the money
    flowing" and adding that if Baptiste "was scamming the FBI, it's
    reasonable to conclude that he was scamming . . . other so-called
    co-conspirators," including "Boncy."
    The bottom line is that despite what the government
    thinks, Boncy's lawyer was hardly defending Baptiste.              So this
    - 16 -
    facet of the government's reversal argument does not assist its
    cause.
    C.
    The government does not like how the judge used the
    cumulative-error doctrine.        To hear it tell it, that doctrine
    simply provides "that there need not be any singularly dispositive
    deficiency."     But it believes that the judge failed to find
    "concrete    ways"   that   any   of     "counsel's   deficiencies   . . .
    contribute[d] to a substantial likelihood of a different result,"
    and because "none would, the cumulative error doctrine" is not in
    play.    We, however, see things differently.
    The cumulative-error doctrine holds that errors not
    individually reversible can become so cumulatively.           See, e.g.,
    United States v. Sepulveda, 
    15 F.3d 1161
    , 1195-96 (1st Cir. 1993).
    That is because "[i]ndividual errors, insufficient in themselves
    to necessitate a new trial, may in the aggregate have a more
    debilitating effect" and thus add up to prejudice. See 
    id.
     (double
    emphasis added).     And we have long held that the prejudice inquiry
    under Strickland can be a cumulative one as to the effect of all
    of counsel's slipups that satisfy the deficient-performance prong
    — meaning that a defendant need show it more likely than not that
    the several blunders, even if not prejudicial on their own,
    prejudiced him when taken together.        See Dugas v. Coplan, 428 F.3d
    - 17 -
    317, 335 (1st Cir. 2005) (proclaiming that "Strickland clearly
    allows the court to consider the cumulative effect of counsel's
    errors in determining whether a defendant was prejudiced" (quoting
    Kubat v. Thieret, 
    867 F.2d 351
    , 370 (7th Cir. 1989))).
    The government makes much of language in United States
    v. Sampson that "the cumulative error doctrine finds no foothold"
    if       no   individual    error   "worked   any   cognizable   harm   to   [the
    defendant's] rights."           See 
    486 F.3d 13
    , 51 (1st Cir. 2007).          But
    we have read that passage as saying that if the combined errors
    resulted        in   an    unfair   trial,    the   cumulative-error    doctrine
    "requires the vacation of a defendant's conviction even though the
    same compendium of errors, considered one by one, would not justify
    such relief."         See United States v. Padilla-Galarza, 
    990 F.3d 60
    ,
    85 (1st Cir. 2021) (double emphasis added, citing Sampson, 
    486 F.3d at 51
    ).
    So what matters is the cumulative effect of counsel's
    errors (even if no error in isolation suffices to establish
    qualifying prejudice) — i.e., the focus must be on the collective
    impact of counsel's deficiencies, some of which we have mentioned:
    •    His raising an entrapment theory, despite being told it had
    no legs — a blooper that essentially put Baptiste in the
    middle of a bribery scheme.
    - 18 -
    •   His not challenging a photo of cash sent from Baptiste's phone
    (a picture counsel first saw at trial, despite getting it
    from prosecutors in discovery), which the government argued
    showed money Baptiste used for bribes — even though Baptiste
    told counsel during the trial that the money represented
    Christmas      bonuses   for    Baptiste's    staff,     not    bribes    for
    Haitian functionaries.
    •   His    not   effectively     contesting     agent    testimony       labeling
    certain words by Baptiste (captured on tape) code for bribes
    (e.g., "tips," "tak[ing] care of . . . people on the ground,"
    "leeway,"      "unforeseen     expenses,"    "something,"       "anything,"
    "stuff    on   the   table,"    "social     programs,"    and    "Christmas
    bonuses") — a failure that tacitly endorsed the idea that the
    agents were not simply speculating about what the words meant.
    •   And    his   not   calling     any   witnesses,     including    a    20-year
    acquaintance of Baptiste and a Haitian legal expert — the
    first of whom (according to an affidavit filed with Baptiste's
    new-trial motion) would have testified that Baptiste had an
    excellent reputation with Haitian officials and so had no
    need to bribe his way into their circle, and the second of
    whom (according to another affidavit) would have testified
    that     certain     actions     (making     political    contributions,
    - 19 -
    lobbying officials by promising them to fund social programs
    to help local communities, etc.) were legal in Haiti.
    The government believes the judge should have found counsel's
    inadequacies "harmless."     But the government attacks each gaffe
    item by item, without providing any convincing basis to question
    the judge's conclusion that the defects as a group cast a shadow
    on the verdict's integrity — which dooms its argument.
    In the same section of its opening brief, the government
    calls the judge's prejudice finding too "hypothetical" because, at
    least in its view, the record lacks a sufficient "description" of
    the tack the defense might take at a retrial and so prevents us
    from doing a prejudice analysis on appeal.         But our discussion of
    the deficiencies bulleted throughout the opinion (in the beginning
    of the "arguments and analysis" section and in preceding paragraph)
    sheds sufficient light on what the defense could do differently at
    a do-over trial.
    D.
    Last but not least is the government's claim that the
    judge   reversibly   erred   by   finding   that   Baptiste's   lawyer's
    ineffectiveness prejudiced Boncy.        This claim has three subparts.
    The first is the government's contention "that the Sixth Amendment
    right to counsel is personal and cannot be asserted vicariously"
    by Boncy (which is the government's "principal argument").          The
    - 20 -
    second is the government's insistence that "[e]ven if" we "construe
    Boncy's claim as an argument that he was prejudiced by joinder of
    the   trials    due   to   the   presentation   of    conflicting   defense
    strategies," his claim would still "fail" because the judge "found
    no such prejudice here" when she ordered them retried together.
    And the third is the government's suggestion that "the prejudice
    the   [judge]   did   find"   has   no   "factual   basis."   Nothing   the
    government says, however, moves the needle in its favor.
    Before getting into the nitty-gritty, it is worth going
    over some of the new-trial basics again — while also amplifying
    some of our earlier points.
    Rule 33 lets a defendant file a new-trial motion "based
    on newly discovered evidence" (Rule 33(b)(1)) or "on any reason
    other than newly discovered evidence" (Rule 33(b)(2), emphasis
    ours).   Rule 33 also says a judge "may" grant a new trial in "the
    interest of justice" (Rule 33(a), emphasis again ours).
    The "interest of justice" catchphrase is undefined.          But
    according to a leading treatise on criminal procedure, Rule 33's
    words vest a judge with "broad powers to grant a new trial" if she
    "concludes for any reason that the trial resulted in a miscarriage
    of justice" (with the caveat that a new-trial motion is "to be
    granted with caution").       3 Sarah N. Welling, Federal Practice and
    Procedure § 581 (4th ed. 2021) [hereinafter Federal Practice and
    - 21 -
    Procedure] (emphasis added).       See generally Veloz, 948 F.3d at 437
    (using the "miscarriage of justice" idiom).              We ourselves have
    stressed the "broad discretion" Rule 33 gives a judge — contrasting
    (in a way that provides some insight into what this means) the
    spacious "interest[] of justice" lingo in Rule 33 with a federal
    habeas statute that lets a judge grant postconviction relief if
    (for example) she "finds . . . that there has been . . . a denial
    . . . of constitutional rights."           Trenkler v. United States, 
    268 F.3d 16
    , 24 (1st Cir. 2001) (quotations omitted).             Or to steal a
    line from the same leading treatise, "[t]he grounds for relief are
    broader under Rule 33 than under [the habeas statute]," because
    "[t]he Rule allows a new trial whenever the interest of justice
    requires it, while the statutory [habeas] remedy . . . for the
    most part reaches only constitutional defects in the proceedings."
    3 Federal Practice and Procedure § 591.          Which is why Rule 33 is
    "likely more enticing to a" defendant than the statute.           Trenkler,
    
    268 F.3d at 24
     (quotations omitted).          And a somewhat related line
    of cases elsewhere — not challenged by the government here —
    recognizes that the "interest of justice" empowers a judge to grant
    a   new   trial   based   on   perceived    unfairness   of   something   not
    amounting to reversible error.        See United States v. Vicaria, 
    12 F.3d 195
    , 198-99 (11th Cir. 1994) (holding that the district judge
    had the discretion to grant a new trial after "conclud[ing]" that
    - 22 -
    he "should have given [a jury] instruction [he] had declined [to
    give]" — even though the judge did not legally err in not giving
    that instruction); Morales, 
    902 F.2d at 606
     (noting that if a
    district    judge   believes     "there    is   a   serious   danger   that   a
    miscarriage of justice has occurred," she can grant a new trial —
    "even if [she] does not think that [she] made any erroneous rulings
    at the trial" (citing our Rothrock opinion, 
    806 F.2d at 321-22
    )).
    A judge's handling of a Rule 33 motion "is ordinarily a
    'judgment call.'"     United States v. Connolly, 
    504 F.3d 206
    , 211
    (1st Cir. 2007) (quoting United States v. Maldonado-Rivera, 
    489 F.3d 60
    , 65 (1st Cir. 2007)).             So when the judge deciding the
    motion is the judge who ran the trial, we owe "an appreciable
    measure of respect . . . to '[her] sense of the ebb and flow of
    the recently concluded'" proceedings.           
    Id.
     (quoting United States
    v. Natanel, 
    938 F.2d 302
    , 313 (1st Cir. 1991)); see also United
    States v. Paniagua-Ramos, 
    135 F.3d 193
    , 197 (1st Cir. 1998)
    (commenting that our review "is deferential to the district court"
    because "the court was present at the trial and had the opportunity
    first hand to observe the evidence, the witnesses, and the jury").
    What this means here is that the government must meet the high
    threshold   of   showing   the    judge    abused    her   discretion.    See
    Connolly, 
    504 F.3d at 211
    ; see also United States v. Rodríguez-
    - 23 -
    Soler,   
    773 F.3d 289
    ,   294   (1st    Cir.    2014)    (calling    abuse   of
    discretion a "difficult standard[]").
    With all that in mind — and knowing too that our job is
    to focus on the arguments that an appellant like the government
    actually makes, not to think up other ones besides, see Cruz-
    Ramos, 987 F.3d at 40; Rivera-Corraliza v. Morales, 
    794 F.3d 208
    ,
    226 (1st Cir. 2015) — we turn to our analysis of the government's
    multidimensional thesis.
    Contrary to the government's position, Boncy did not
    pursue   a   Sixth     Amendment     claim   keyed     to    Baptiste's   lawyer's
    ineffective assistance.          Instead, he pursued a Fifth Amendment
    claim tied to the denial of his own due-process rights — to quote
    again from his motion (emphasis ours, though), he argued that
    "deficiencies      in    the    conduct      of     Baptiste's    trial    counsel
    necessarily affected the jury's view of both defendants in this
    joint trial, thereby depriving Boncy of a fair trial in violation
    of his due process right to a fair trial."                  So we need not worry
    about the government's Sixth Amendment-based first sub-argument.
    Nor need we spend time on the government's second sub-
    argument.      And that is because we accept (without further ado) the
    government's claim that the judge's prejudice analysis did not
    turn on Boncy's being tried jointly with Baptiste, given how she
    (as the government notes) found severance unnecessary.
    - 24 -
    Which    leaves    us    with    the    government's         final    sub-
    argument,      i.e.,    that     the     judge's      prejudice    finding         lacks
    evidentiary support — this, despite the fact that the judge cited
    to the record lots of times.              Anyway, the government's initial
    brief does not tie its attack to the controlling clearly-erroneous
    standard — a hard-to-satisfy test, seeing how a "challenger must
    show   that    the    contested    finding     stinks    like     'a   5    week   old,
    unrefrigerated,        dead    fish.'"        See    United   States       v.   Rivera-
    Carrasquillo, 
    933 F.3d 33
    , 42 (1st Cir. 2019) (quoting Toye v.
    O'Donnell (In re O'Donnell), 
    728 F.3d 41
    , 46 (1st Cir. 2013)),
    cert. denied, 
    140 S. Ct. 2691
     (2020); see also United States v.
    Oliveira, 
    907 F.3d 88
    , 92 (1st Cir. 2018) (stating that the
    challenger's arguments must cause us to form "a strong, unyielding
    belief that a mistake has been made" (quotation omitted)); United
    States v. Cates, 
    897 F.3d 349
    , 352 (1st Cir. 2018) (highlighting
    how clear error's "heights are difficult to scale"). And it should
    now go without saying (though we say it anyway) that an appellant
    risks waiver if its opening brief does not properly develop
    arguments showing how its claims can succeed under the proper
    review standard.         See Cruz-Ramos, 987 F.3d at 40 (collecting
    authority); see also Rivera-Carrasquillo, 933 F.3d at 53.
    But even brushing waiver away, we cannot stamp the
    challenged findings clearly erroneous.                  As noted several pages
    - 25 -
    ago, the judge found (again, with specific citations to the record)
    that Boncy's lawyer wanted to expose Baptiste to the jury "as the
    primary    driver"   of    the    charged   conspiracy   to     bribe      foreign
    officials — a strategy, to quote the government's lower-court
    papers, that "Boncy's counsel" pursued as he basically "led the
    defense side of the case," almost from the start.                    And "[g]iven
    that . . . Boncy played a different role in the charged conspiracy
    than . . . Baptiste" — to quote some more from the judge's order
    — "his counsel might well have decided to say and do considerably
    less during trial to emphasize [Boncy's] more minor participation
    in the alleged conspiracy had he not had to carry the defense so
    much on his own."         Looking to deflect the force of the judge's
    finding, the government says that Boncy's lawyer also sometimes
    portrayed Baptiste as running an uncharged conspiracy to rip-off
    the FBI (as we intimated above in section B, Boncy's counsel
    occasionally theorized that "the 5 percent" was Baptiste's self-
    serving scam to line his pockets — and his alone).               Still, no one
    can seriously doubt that Boncy's counsel worked to show that the
    charged conspiracy did not exist. Yet, Baptiste's lawyer basically
    conceded     the   charged       conspiracy's   existence       by    hyping   an
    entrapment    theory      (and   to   be   perfectly   clear:         by   charged
    conspiracy, we mean the conspiracy involving Baptiste and Boncy).
    Also conflicting with his bid to show his client had no part in
    - 26 -
    the charged conspiracy, Boncy's counsel — as the judge supportably
    found — had "to play an outsized role at trial rather than pursue
    his preferred defense strategy for his own client." Which explains
    why the government's arguments do not provoke a strong, unyielding
    belief that the judge botched the prejudice finding.         And to the
    extent the government thinks a plausible view of the facts supports
    its no-prejudice position, we need only say that a judge's choice
    among supportable alternatives cannot be clearly erroneous.          See
    Cooper v. Harris, 
    137 S. Ct. 1455
    , 1465 (2017) (emphasizing that
    "[a] finding that is 'plausible' in light of the full record —
    even if another is equally or more so — must govern" (emphasis
    added and citation omitted)).
    The   district   judge    (not   we)   actually   heard   the
    witnesses, saw how each counsel performed, and watched the jurors
    as the proceedings unfolded.        That put her (not us) in the best
    spot to decide if the interest of justice demanded a new trial.
    See Connolly, 
    504 F.3d at 211
    .       For, to borrow the words of Judge
    Posner, "[t]he trial judge will always be in a better position
    than the appellate judges to assess the probable reactions of
    jurors in a case over which [she] has presided," because she can
    understand, "as we cannot, . . . the atmosphere of the trial —
    that congeries of intangibles that no stenographic transcript can
    convey."   See United States v. Bruscino, 
    687 F.2d 938
    , 941 (7th
    - 27 -
    Cir. 1982) (en banc) (per Posner, J.).           Perhaps if we had been
    there we would have decided matters differently.          Or perhaps not.
    See   generally   Glossip   v.   Gross,    
    576 U.S. 863
    ,   881   (2015)
    (instructing us not to "overturn a finding 'simply because [we
    are] convinced that [we] would have decided the case differently'"
    (alteration in original and quoting Anderson v. City of Bessemer
    City, 
    470 U.S. 564
    , 573 (1985))).         But because our job is not to
    play district judge, we cannot substitute our judgment for her
    discretion and ring-side insights — unless those insights sunk to
    an abuse of discretion.     See Veloz, 948 F.3d at 437.        And as with
    its other claims, this multilayered argument does not satisfy the
    government's heavy burden of showing an abuse of discretion.
    We end this segment by again emphasizing a fundamental
    point.   "The premise of our adversarial system is that appellate
    courts do not sit as self-directed boards of legal inquiry and
    research, but essentially as arbiters of legal questions presented
    and argued by the parties before them."          See NASA v. Nelson, 
    562 U.S. 134
    , 147 n.10 (2011) (quoting Carducci v. Regan, 
    714 F.2d 171
    , 177 (D.C. Cir. 1983) (per Scalia, J.)); accord Greenlaw v.
    United States, 
    554 U.S. 237
    , 243 (2008) (stating that "we rely on
    the parties to frame the issues for decision and assign to courts
    the role of neutral arbiter of matters the parties present").            So
    in doing what judges are paid to do, we have taken — and, it turns
    - 28 -
    out, rejected — the government's arguments as we have found them.
    Maybe there is a better argument for why a new trial would not
    serve "the interest of justice" — e.g., maybe there is some other
    limiting principle to that legal standard's broad reach.             But if
    a better argument does exist, we need not deal with it today:             it
    is enough for us to hold (as we do) that the arguments the
    government does make do not convince us that the reach of this
    broad standard should be circumscribed in this instance.
    Wrap Up
    No one doubts (at least, no one should doubt) that "[t]he better
    the lawyers at a trial are, provided they are evenly matched, the more likely
    is the trier of fact to find the truth." See Morales, 
    902 F.2d at 609
    . So
    while both sides here face the expense of retrial, "[t]he result will be a .
    . . proceeding much more likely to render a verdict in which the legal system
    and the public can have confidence."4   See 
    id.
    And thus, for the reasons recorded above, we affirm the judge's
    grant of new trials.
    4  Given our holding, we need not consider Baptiste's and Boncy's
    alternative grounds for affirmance — e.g., Baptiste's argument that a judge
    can grant a new trial even if counsel's performance did not fall into the
    category of a Sixth Amendment violation; or Boncy's argument that he should
    get a new trial based on the government's destruction of certain evidence.
    See generally PDK Labs. Inc. v. DEA, 
    362 F.3d 786
    , 799 (D.C. Cir. 2004)

    that "if it is not necessary to decide more, it is necessary not to decide
    more").
