    PREFACE
    La Rompe ONU (just "La Rompe" from now on) was one of
    the largest and most violent of Puerto Rico's street gangs.
    Another was La ONU.         Deadly rivals, each wreaked much havoc on
    Puerto Rico through serial drug sales, violent robberies and
    carjackings, and ghastly killing sprees.
    After law enforcement took La Rompe down, La Rompe
    members     Rodríguez-Torres,       Sánchez-Mora,     Rodríguez-Martínez,
    Vigio-Aponte, and Guerrero-Castro (their full names and aliases
    appear above) found themselves indicted, then convicted, and then
    serving serious prison time for committing some or all of the
    following crimes: conspiracy to violate RICO (short for "Racketeer
    Influenced       and   Corrupt   Organizations   Act"),   see   
    18 U.S.C. § 1962
    (d); conspiracy to possess and distribute narcotics, see 
    21 U.S.C. §§ 846
    , 860(a); use and carry of a firearm in relation to
    a drug-trafficking crime, see 
    18 U.S.C. § 924
    (c)(1)(A); and drive-
    by shooting, see 
    18 U.S.C. §§ 36
    (b)(2)(A), 2 (aiding and abetting)
    — to list only a few.            The testimony of several cooperating
    witnesses    —    Luis   Yanyoré-Pizarro,    Oscar   Calviño-Ramos,    Luis
    Delgado-Pabón, and Oscar Calviño-Acevedo (persons indicted with
    our defendants, but who later pled guilty) — helped seal their
    fate.
    - 3 -
    Collectively, our defendants' appeals (now consolidated)
    raise a battery of issues concerning the sufficiency of the
    evidence for the RICO-conspiracy, drug-conspiracy, and firearms
    convictions; the admission of out-of-court statements about a
    murder-by-choking incident; the correctness of the RICO-conspiracy
    jury instructions; and the reasonableness of two of the sentences.1
    We address these subjects in that order, filling in the details
    (like which defendant makes which claims) as we move along.2   But
    for anyone wishing to know our ending up front, when all is said
    and done we affirm.
    1 Rodríguez-Martínez also argues that his trial attorney
    rendered ineffective assistance by failing to object to certain
    jury instructions and to any aspect of the sentencing. He debuts
    the argument here, however.     And the record is not suitably
    developed for deciding that issue now. So we dismiss this claim,
    without prejudice to his raising it (if he wishes) in a timely
    postconviction-relief petition under 
    28 U.S.C. § 2255
    . See, e.g.,
    United States v. Tkhilaishvili, 
    926 F.3d 1
    , 20 (1st Cir. 2019).
    2 We do have a small speed bump to clear first, however.
    Rodríguez-Torres, Sánchez-Mora, and Vigio-Aponte try to join some
    of their coappellants' arguments. There is a mechanism for doing
    this, see Fed. R. App. P. 28(i), though appellants must "connect
    the arguments" they wish to "adopt[] with the specific facts
    pertaining to [them]," see United States v. Bennett, 
    75 F.3d 40
    ,
    49 (1st Cir. 1996) — i.e., they must show "that the arguments"
    really are "transferable" from their coappellants' case to theirs,
    see United States v. Ramírez-Rivera, 
    800 F.3d 1
    , 11 n.1 (1st Cir.
    2015) (quotation marks omitted). We question whether Rodríguez-
    Torres and Sánchez-Mora did enough to satisfy this standard. But
    because the arguments are not difference-makers, "we will assume"
    (without holding) "that each appellant effectively joined in the
    issues that relate to his situation." United States v. Rivera-
    Carrasquillo, 
    933 F.3d 33
    , 39 n.5 (1st Cir. 2019).

    SUFFICIENCY CLAIMS
    Overview
    Rodríguez-Torres, Rodríguez-Martínez, Guerrero-Castro,
    and Sánchez-Mora (but not Vigio-Aponte) claim that the prosecution
    submitted    insufficient     evidence    to   sustain   some   of   their
    convictions:
       Rodríguez-Torres challenges his RICO- and drug-conspiracy
    convictions, plus his firearm conviction;
       Rodríguez-Martínez contests his RICO- and drug-conspiracy
    convictions;
       Guerrero-Castro questions his RICO-conspiracy and firearm
    convictions; and
       Sánchez-Mora (by adopting his codefendants' arguments that
    apply to his situation) disputes his RICO- and drug-
    conspiracy convictions.
    And so they fault the judge for denying their motions for judgments
    of acquittal.    We will turn to the specifics of their arguments
    and the government's counterarguments in a minute.          But like the
    government, we find none of their claims persuasive.
    Analysis
    Standard of Review
    We assess preserved sufficiency claims de novo (with
    fresh eyes, in plain English), reviewing the evidence, and making
    all inferences and credibility choices, in the government's favor
    — reversing only if the defendant shows that no rational factfinder
    - 5 -
    could have found him guilty.        See, e.g., Ramírez-Rivera, 800 F.3d
    at 16; United States v. Casas, 
    356 F.3d 104
    , 126 (1st Cir. 2004).
    For convenience, we'll call this the regular sufficiency standard.
    An unpreserved challenge, contrastingly, requires reversal only if
    the defendant shows — after viewing the evidence the exact same
    government-friendly way — that allowing his conviction to stand
    will work a "clear and gross injustice."         See, e.g., United States
    v. Freitas, 
    904 F.3d 11
    , 23 (1st Cir. 2018); United States v.
    Foley, 
    783 F.3d 7
    , 12-13 (1st Cir. 2015) (calling the clear-and-
    gross   injustice    metric     a   "stringent   standard"    that    is   "a
    particularly exacting variant of plain error review").               For easy
    reference, we'll call this the souped-up sufficiency standard.
    Adopting a scorched-earth approach, the parties fight
    over which standard to apply.       Convinced that they preserved their
    sufficiency     arguments,      Rodríguez-Torres,     Rodríguez-Martínez,
    Guerrero-Castro, and Sánchez-Mora argue that we should use the
    regular sufficiency standard.          Unimpressed by their assertions,
    the government believes that the quartet "waived" aspects of their
    arguments     and   that   we   must   therefore    apply    the   souped-up
    sufficiency standard to those claims.        But rather than spend time
    grappling with the intricacies of this issue, we will assume
    arguendo in their favor that they preserved each sufficiency
    argument.

    RICO-Conspiracy Crime
    RICO makes it a crime "for any person employed by or
    associated with any enterprise engaged in, or the activities of
    which       affect,   interstate   or   foreign   commerce,    to   conduct   or
    participate,      directly    or   indirectly,    in   the   conduct   of   [an]
    enterprise's affairs through a pattern of racketeering activity"
    — or to conspire to do so.         See 
    18 U.S.C. § 1962
    (c), (d).       Broadly
    speaking (we will have more to say on this below), a RICO-
    conspiracy conviction requires proof that the defendant knowingly
    joined the conspiracy, agreeing with one or more coconspirators
    "to further [the] endeavor which, if completed, would satisfy all
    the elements of a substantive [RICO] offense."               Salinas v. United
    States, 
    522 U.S. 52
    , 65 (1997); see also Aetna Cas. Sur. Co. v. P
    & B Autobody, 
    43 F.3d 1546
    , 1562 (1st Cir. 1994).
    Rodríguez-Torres, Rodríguez-Martínez, Guerrero-Castro,
    and Sánchez-Mora offer a litany of reasons why the evidence does
    not support their RICO-conspiracy convictions.                Disagreeing with
    everything they say, the government thinks that the evidence is
    just fine.       We side with the government.3
    3
    A quick heads-up: in a part of our opinion addressing the
    defendants' jury-charge complaints, the parties argue over whether
    the judge properly instructed on the enterprise, interstate-or-
    foreign-commerce, association, participation, and mental-state
    elements. Those arguments are not relevant here, however, given
    how the defendants frame their sufficiency challenges.
    - 7 -
    (i)
    enterprise
    Enterprises under RICO include "any union or group of
    individuals associated in fact although not a legal entity."               See
    United States v. Turkette, 
    452 U.S. 576
    , 578 n.2 (1981); see also
    Ramírez-Rivera, 800 F.3d at 19.           Such so-called association-in-
    fact       enterprises   may   be   "proved   by   evidence   of   an   ongoing
    organization, formal or informal, and by evidence that the various
    associates function as a continuing unit."           See Turkette, 
    452 U.S. at 583
    .       The group need not have some decisionmaking framework or
    mechanism for controlling the members. See Boyle v. United States,
    
    556 U.S. 938
    , 948 (2009) (holding that a RICO enterprise "need not
    have a hierarchical structure or a 'chain of command'; decisions
    may be made on an ad hoc basis and by any number of methods — by
    majority vote, consensus, a show of strength, etc.").              Instead the
    group must have "[1] a purpose, [2] relationships among those
    associated with the enterprise, and [3] longevity sufficient to
    permit these associates to pursue the enterprise's purpose."4               
    Id. at 946
    .
    As to [1] — "purpose" — the group must share the "common
    purpose of engaging in a course of conduct."              
    Id.
          As to [2] —
    "relationship" — there must also be evidence of "interpersonal
    4   We added the bracketed numbers for ease of discussion.
    - 8 -
    relationships" calculated to effect that purpose, i.e., evidence
    that the group members came together to advance "a certain object"
    or "engag[e] in a course of conduct."            
    Id.
     (quotation marks
    omitted).   And as to [3] — "longevity" — the group must associate
    based on its shared purpose for a "sufficient duration to permit
    an association to 'participate' in [the enterprise's affairs]
    through   'a   pattern   of   racketeering    activity,'"   
    id.,
       though
    "nothing in RICO exempts an enterprise whose associates engage in
    spurts of activity punctuated by periods of quiescence," 
    id. at 948
    .   Also and importantly, because RICO's plain terms "encompass
    'any . . . group of individuals associated in fact,' . . . the
    definition has a wide reach," meaning "the very concept of an
    association in fact is expansive."        
    Id. at 944
     (emphasis added by
    the Boyle Court).
    Measured against these legal standards, the record —
    visualized most favorably to the government — adequately shows
    that La Rompe operated as an association-in-fact enterprise.
    For starters, the evidence reveals La Rompe's purpose:
    to get filthy rich by selling drugs at La Rompe-controlled housing
    projects, using violence (and deadly violence at that) whenever
    necessary to protect and expand its turf.       As cooperator Delgado-
    Pabón put it, La Rompe's "purpose" was "to make the organization
    bigger" and "stronger" — "to control all of the housing projects
    - 9 -
    in the metro area" so that it would be rolling in money.        On top
    of that, the evidence shows the necessary relationships between La
    Rompe members:    associates named their group "La Rompe ONU,"
    reflecting that they saw themselves as a united, organized group
    of drug traffickers — the "ONU" stands for "Organización de
    Narcotraficantes Unidos" (in English, "Organization of United Drug
    Traffickers"); self-identified as La Rompe "members," flashing a
    hand signal to show their loyalty; got together daily to peddle
    massive amounts of drugs at La Rompe's many drug points; had
    meetings    to   discuss   decisions   that     "[a]ffect[ed]      the
    organization," like whether to kill a traitor or take over a La
    ONU-controlled housing project (La Rompe and La ONU were archfoes,
    don't forget), or how to keep the peace among the members; worked
    together — pooling resources, for example (manpower, guns, and
    cars, etc.) — to boost profits and gain more territory, principally
    through jointly-undertaken activities like robberies, carjackings,
    and murders; and followed La Rompe "rules" like their lives were
    on the line — because they were.   And finally, the evidence shows
    La Rompe continued as a cohesive unit for at least eight years.
    See Ramírez-Rivera, 800 F.3d at 19 (finding similar evidence "more
    than" adequate to prove "a RICO enterprise").
    Though not necessary thanks to Boyle (which remember
    held that a RICO enterprise "need not have a hierarchical structure
    - 10 -
    or a "chain of command'; decisions may be made on an ad hoc basis
    and by any number of methods — by majority vote, consensus, a show
    of strength, etc."), the evidence also shows that La Rompe had
    business-like traits as well.           In addition to its name, meetings,
    and rules, La Rompe had a loose hierarchical structure.                     Josué
    Vázquez-Carrasquillo was La Rompe's "supreme leader," and Vigo-
    Aponte was its "second" leader.           Each La Rompe-controlled housing
    project had a La Rompe-appointed "leader" and drug-point owners,
    the   latter     of    whom   had   responsibility    over    "employees"    like
    enforcers, sellers, runners, and lookouts.                   Also much like a
    business, La Rompe rewarded good performance and loyalty.               In the
    words of cooperator Calviño-Acevedo, "practically all of us, we
    worked    for    the     organization   like    normal    employees,"   growing
    "within the organization" to the point "we'd be given a drug
    point."    One way to advance within La Rompe was by being close to
    the "boss," Vázquez-Carrasquillo.              Another way was by "killing
    people."       And with these extra structural features, the evidence
    here far surpasses what Boyle requires for a RICO enterprise.
    Rodríguez-Torres,      Guerrero-Castro,       and   Sánchez-Mora
    resist this conclusion on several grounds.               The government sees no
    merit in any of them.          Neither do we.
    Despite conceding in their appellate briefs that La
    Rompe    was    indeed    a   "drug   trafficking    organization"    (emphasis
    - 11 -
    ours), the trio argues that La Rompe was not an enterprise because
    (in their telling) the housing-project crews were "independen[t]"
    entities that did not "coordinat[e]" with each other. The evidence
    cuts against them, however.      According to the record, while there
    were "different crews," La Rompe "controlled" the housing-project
    drug points — with "one same boss" (Vázquez-Carrasquillo) at the
    top.   And everyone in the organization — from the supreme leader
    and his second-in-command, to the housing-project leaders, to the
    drug-point owners, to the low-level employees — were La Rompe
    members who (among other things) had to follow the organization's
    rules or else (with the "or else" ranging all the way from a
    beating, to death).      Unsurprisingly then, La Rompe members often
    worked together, regardless of crew affiliation.              One example is
    that La Rompe frequently "call[ed] in several enforcers from
    different   groups"    when   taking   over     La   ONU-controlled   housing
    projects.   Another example is that La Rompe sometimes used members
    from across the organization when carrying out killings.                    See
    generally Ramírez-Rivera, 800 F.3d at 19 (holding that, although
    La ONU came about as a "merging of smaller gangs that still
    operated their existing drug points," it qualified as a RICO
    enterprise because (among other things) the groups combined their
    efforts   "to   sell   drugs,   and    later,    to    also   stomp   out   the
    competition (specifically, La Rompe)").
    - 12 -
    Not so fast, say Rodríguez-Torres, Guerrero-Castro, and
    Sánchez-Mora.   They contend that crews from different housing
    projects did not "share . . . resources for purchase of narcotics
    or firearms," which, they believe, kiboshes any notion that La
    Rompe was a RICO enterprise.     But they ignore Yanyoré-Pizarro's
    testimony that "La Rompe" committed robberies and carjackings to
    (among other things) "get the money to maintain drug points that
    we were acquiring little by little" and to "buy materials, buy
    weapons, buy ammo, bullets."     And they ignore Calviño-Acevedo's
    testimony to the same effect.5
    In a somewhat related vein, Rodríguez-Torres, Guerrero-
    Castro, and Sánchez-Mora insist that La Rompe did not own or have
    "a cache of firearms."   But the testimony shows that La Rompe had
    "pistols, rifles, AR-15s, AK-47s," which, when "not in the hands
    of enforcers," the organization stored in various apartments.
    5 The trio also blasts the government for not producing
    evidence of how La Rompe members communicated with or even knew
    each other.     The gaping hole in this argument is that the
    government can prove a RICO conspiracy without showing that each
    conspirator "knew all the details or the full extent of the
    conspiracy, including the identity and role of every other
    conspirator." Aetna Cas. Sur. Co., 
    43 F.3d at 1562
    . Still, the
    evidence shows that La Rompe members knew each other by nickname
    or identified each other by hand signal. And a rational jury could
    reasonably infer that members developed a level of familiarity
    with each other by, for example, attending organizational meetings
    or committing countless crimes together. "[A]s [you] grew in the
    organization," Calviño-Acevedo told the jury, "you learn[ed] . . .
    who's who and who's not who."
    - 13 -
    Enforcers could own their own guns.      But leaders could take them
    away if the enforcers did "something wrong."       And enforcers also
    had to lend their guns to other La Rompe members when needed.
    Still trying to spin the gun evidence in their favor,
    the trio claims that La Rompe members would "fight over, steal and
    even kill each other to get firearms."          But the episode they
    discuss involved a non-La Rompe member (known as "Colo") who sold
    guns to one La Rompe crew who was having an "internal war" with
    another crew (cooperator Calviño-Acevedo and his colleagues killed
    Colo, but they also killed a four-year-old boy with a stray
    bullet).   Despite the conflict between the crews, Calviño-Acevedo
    testified that both crews were still part of La Rompe.
    Curiously,   Rodríguez-Torres,     Guerrero-Castro,   and
    Sánchez-Mora claim that "La Rompe had no economic activity" or
    "financial      organization"   and   derived     no   "economic   or
    organizational benefit" from its members' drug dealing.       This is
    curious because making money through drug selling was La Rompe's
    raison d'être.     Whether drug sales directly benefited La Rompe is
    irrelevant, because the sales contributed to La Rompe's goal of
    enriching its members.    And the drug dealing did benefit La Rompe
    organizationally, because one of La Rompe's main goals was "to
    control all of the housing projects of the metro area," which
    required tons of cash.     Insofar as the trio means that La Rompe
    - 14 -
    did not have a bank account or balance sheet, these formalities
    are not required for an association-in-fact enterprise. See Boyle,
    
    556 U.S. at 948
    .         Regardless, some La Rompe members did perform
    accounting functions — Rodríguez-Torres, for example, "took care
    of     [Vázquez-Carrasquillo's]       finances"       and    helped    with    Vigo-
    Aponte's "finances" too.
    Taking another tack, the trio claims that La Rompe did
    not pay Yanyoré-Pizarro and Calviño-Acevedo for their work as
    enforcers — which, they contend, shows no enterprise existed.                   But
    Yanyoré-Pizarro      testified      that    some    owners    gave    him   "[c]ars,
    firearms,"    and    sometimes      "cash"    for    contract    killings.       And
    Calviño-Acevedo testified that "the organization" compensated him
    for killings by giving him "[c]ountless drug points."
    As a last gasp, Rodríguez-Torres, Guerrero-Castro, and
    Sánchez-Mora say that we should see the enterprise issue their
    way,    because     no   evidence    shows    that    La     Rompe    had   "colors,
    initiation rites, and a formal hierarchy" or even "trained" its
    members "in the use of weapons and criminal conduct."                           This
    argument is beside the point.                When they exist, such features
    certainly are relevant to the enterprise inquiry.                      But none is
    necessary.     And the absence of any is not determinative.                      See
    Boyle, 
    556 U.S. at 948
    ; see also United States v. Nascimento, 
    491 F.3d 25
    , 33 (1st Cir. 2007).               As explained above, however, the
    - 15 -
    record does show that La Rompe had these or similar features — La
    Rompe members identified themselves with a hand signal, had a rite
    of passage (killing to get a drug point), and a loose hierarchical
    structure.      To this we add that when cooperator Calviño-Acevedo
    joined   La    Rompe,   a    La     Rompe    leader       "explained       to   [him]   how
    everything was," which disposes of their no-training suggestion.
    The   bottom    line     is     that    the       government      presented
    sufficient     evidence      that    La     Rompe    was       an   association-in-fact
    enterprise, despite what the trio thinks.
    (ii)
    effect on interstate or foreign commerce
    Prosecutors     had     to    show     La    Rompe's      interstate-      or
    foreign-commerce effects. Insisting that "La Rompe did not operate
    outside of Puerto Rico" and that the "violent actions imputed to
    La Rompe occurred in Puerto Rico," Rodríguez-Torres, Guerrero-
    Castro, and Sánchez-Mora contend that "no evidence" shows that La
    Rompe    impacted    "interstate          commerce"       in    a   RICO   sense.       The
    government disagrees.         And so do we.
    La Rompe need only have had a "de minimis" effect on
    interstate or foreign commerce, see Ramírez-Rivera, 800 F.3d at 19
    — which is a fancy way of saying that "RICO requires no more than
    a slight effect upon interstate commerce," see United States v.
    Doherty, 
    867 F.2d 47
    , 68 (1st Cir. 1989).                  And viewed in the proper
    light — afresh and in a way most pleasing to the prosecution — the
    - 16 -
    record shows that La Rompe's many drug points ran daily (some on
    a   24-hour,   7-day-a-week        basis),     selling   endless   amounts   of
    cocaine, heroin, and marijuana, to name just some of the narcotics
    dealt there. A government expert testified that cocaine and heroin
    are not produced in Puerto Rico, and so must be imported from South
    American countries like Colombia. He also testified that marijuana
    is not produced in Puerto Rico (except for the hydroponic form,
    which is "very limited"), and so must be imported from states like
    Arizona,    California,      and    Texas.       Cooperator   Yanyoré-Pizarro
    testified    that   a   La    Rompe    leader     called   "Pekeko"   imported
    "marijuana pounds" from Texas.               And cooperator Calviño-Acevedo
    testified that he supplied La Rompe with "pounds of marijuana"
    that he got "through the mail."
    All of this evidence shows that La Rompe's activities
    affected not only foreign commerce, but also interstate commerce.
    See Ramírez-Rivera, 800 F.3d at 19-20.
    (iii)
    participation
    Prosecutors also had to prove that the defendants had
    "some part in directing" La Rompe's affairs — i.e., that they
    participated in the "operation or management" of the enterprise
    itself.    See id. at 20 (relying in part on Reves v. Ernst & Young,
    
    507 U.S. 170
    , 179, 183 (1993), in assessing the evidentiary
    sufficiency of the government's RICO-conspiracy case); see also
    - 17 -
    Reves, 
    507 U.S. at 184-85
     (explaining that persons who participate
    in the operation or management of the enterprise's affairs will,
    of course, necessarily meet the RICO statute's requirement that he
    be "associated with" the enterprise). "An enterprise is 'operated'
    not just by upper management but also by lower rung participants
    in the enterprise who are under the direction of upper management."
    Reves, 
    507 U.S. at 184
    .
    Calling   the   government's   participation   evidence   too
    skimpy,   Rodríguez-Torres,    Rodríguez-Martínez,   Guerrero-Castro,
    and Sánchez-Mora variously argue that "there was no testimony"
    that they were "leader[s]" or that they "participated in decision
    making events" — in their view of things, they were "merely
    present" when key events went down.       As the government notes, we
    must take all evidence and draw all reasonable inferences in the
    prosecution's favor — not theirs.         And having done so, we see
    plenty of evidence pegging them as drug-point owners:       Rodríguez-
    Torres owned a marijuana drug point in the La Rompe-controlled
    housing project of Covadonga; Rodríguez-Martínez owned a heroin
    drug point in the La Rompe-controlled housing project of Monte
    Hatillo; Guerrero-Castro owned a marijuana drug point in the La
    Rompe-controlled housing project of Los Laureles; and Sánchez-Mora
    owned a heroin drug point in the La Rompe-controlled housing
    project of Covadonga. Which is important because drug-point owners
    - 18 -
    played   a    critical   role   in   achieving    La   Rompe's   goal   of
    "control[ling] all of the housing projects of the metro area" to
    generate "more money" so La Rompe could "grow and have more power."
    As in Ramírez-Rivera, these facts easily satisfy the
    participation element.      See 800 F.3d at 20 (holding that drug-
    point ownership met the operation-or-management test).6
    (iv)
    pattern of racketeering
    A pattern of racketeering activity requires at least two
    predicate acts of racketeering within ten years of each other.
    See 
    18 U.S.C. § 1961
    (5); United States v. Tavares, 
    844 F.3d 46
    , 54
    (1st Cir. 2016).     Predicate acts include murder and drug dealing,
    as well as aiding and abetting such acts.        See Ramírez-Rivera, 800
    6 Citing out-of-circuit law — United States v. Wilson, 
    605 F.3d 985
     (D.C. Cir. 2010), and Smith v. Berg, 
    247 F.3d 532
     (3d
    Cir. 2001) — the government suggests (first quoting Wilson, then
    quoting Smith, adding its own emphasis) that "[l]iability for a
    RICO-conspiracy offense . . . requires only that the defendant has
    'knowingly agree[d] to facilitate a scheme which includes the
    operation or management of a RICO enterprise'" and that under the
    RICO-conspiracy statute, "the defendant need not 'himself
    participate in the operation or management of an enterprise.'"
    The evidence in our Ramírez-Rivera case showed that the challenging
    defendants actually played a part in directing the enterprise's
    affairs, given their drug-point-owner status — which necessarily
    showed that they agreed to a scheme that included such
    participation.   So too here.    Which is why we need not decide
    whether to adopt the Wilson/Smith approach in this case, thus
    leaving that issue for another day. See generally PDK Labs., Inc.
    v. DEA, 
    362 F.3d 786
    , 799 (D.C. Cir. 2004) (Roberts, J., concurring
    in part and concurring in the judgment) (noting that "if it is
    not necessary to decide more, it is necessary not to decide more").
    - 19 -
    F.3d at 20 (citing 
    18 U.S.C. § 1961
    (1)). The acts must be "related"
    and "amount to or pose a threat of continued criminal activity."
    H.J. Inc. v. Nw. Bell Tel. Co., 
    492 U.S. 229
    , 239 (1989).       A RICO-
    conspiracy defendant, however, need not have personally committed
    — or even agreed to personally commit — the predicates.             See
    Salinas, 
    522 U.S. at 63
    ; United States v. Cianci, 
    378 F.3d 71
    , 90
    (1st Cir. 2004).      All the government need show is that the
    defendant agreed to facilitate a scheme in which a conspirator
    would commit at least two predicate acts, if the substantive crime
    occurred.   See, e.g., Salinas, 
    522 U.S. at 64-65
    ; Cianci, 
    378 F.3d at 90
    .
    Without   citing    to   the   record,   Rodríguez-Torres,
    Guerrero-Castro, and Sánchez-Mora claim that cooperators offered
    "discredit[able]" testimony because they (the cooperators) "could
    not" provide dates and times for some events — and thus, the thesis
    runs, the government did not prove the pattern-of-racketeering
    element.    But again, and as the government stresses, we must
    inspect the record in the light most flattering to the government's
    theory of the case, resolving all credibility issues and drawing
    all justifiable inferences in favor of the jury's guilty verdicts
    — which undercuts any credibility-based argument.
    Rodríguez-Torres,    Guerrero-Castro,    and   Sánchez-Mora
    also suggest that "while the first predicate act may be the drug
    - 20 -
    trafficking imputed to [them], there is simply no additional
    evidence to establish another predicate act as required by the
    RICO statute."       To the extent they suggest that the two predicate
    acts must be of different types, they are wrong.              See generally
    Boyle, 
    556 U.S. at 948
     (noting that "a group that does nothing but
    engage in extortion through old-fashioned, unsophisticated, and
    brutal means may fall squarely within [RICO's] reach"); Fleet
    Credit Corp. v. Sion, 
    893 F.2d 441
    , 444-48 (1st Cir. 1990) (holding
    that multiple acts of "mail fraud" can satisfy the pattern-of-
    racketeering requirement, provided they amount to — or constitute
    a threat of — continuing criminal activity).          Nevertheless, and as
    the government is quick to point out, the evidence shows that La
    Rompe members — including drug-point owners (which all three were)
    —   committed   or    aided   and   abetted   scads   of   drug   deals   (the
    government estimated that La Rompe sold thousands of kilograms
    each of marijuana, cocaine, crack cocaine, and heroin), plus scores
    of murders (drug-point owners, for instance, used "enforcers" to
    "kill[] people").7       These acts were related to each other (they
    7Sticking with murder for just a bit, we note that cooperator
    Yanyoré-Pizarro fingered Rodríguez-Torres as a participant in the
    drive-by killing of a La Rompe leader who had "turned" on the
    organization (a killing we discuss in the sentencing section of
    this opinion). And cooperator Calviño-Acevedo said that Guerrero-
    Castro "kill[ed] people" for La Rompe too.
    - 21 -
    were La Rompe's business, after all), occurred over a lengthy
    period (at least eight years) and, at a minimum, threatened to
    keep on going (the trio makes no convincing argument to the
    contrary).
    All in all, the government offered enough evidence of a
    racketeering pattern.
    (v)
    knowingly joined
    Each    RICO-conspiracy       defendant    must       have    knowingly
    joined the conspiracy.            See, e.g., Aetna Cas. Sur. Co., 
    43 F.3d at 1562
    .     And "[a]ll that is necessary to prove" this RICO-conspiracy
    element is to show "that the defendant agreed with one or more co-
    conspirators to participate in the conspiracy."                      See Ramírez-
    Rivera, 800 F.3d at 18 n.11 (quotation marks omitted).                    Rodríguez-
    Torres,     Rodríguez-Martínez,         Guerrero-Castro,       and    Sánchez-Mora
    think that the government's evidence falls short of satisfying
    that element, because, the argument goes, they were at most merely
    present     (which    is    all      they'll    cop   to)     at   the    scene   of
    conspiratorial deeds.             But we agree with the government that a
    rational jury could infer their knowing agreement to conspire from
    their actual participation as drug-point owners.                   See id.    Making
    money through drug dealing was a key object of the conspiracy.
    And   a   reasonable       jury    could   conclude    that    their      drug-point
    ownership was intended to — and actually did — accomplish that
    - 22 -
    object.   See id. (finding the knowledge element met by similar
    evidence).
    So   the    government    presented   ample     evidence      on    this
    element as well.
    Drug-Conspiracy Crime
    Moving on from the RICO-conspiracy crime, Rodríguez-
    Torres, Rodríguez-Martínez, and Sánchez-Mora protest that the
    government provided insufficient evidence that they knowingly
    joined the drug conspiracy.           Not so, says the government.             As for
    us, we agree with the government that their challenges necessarily
    fizzle because (as just indicated) adequate evidence showed that
    they knowingly joined the RICO conspiracy, of which the drug
    conspiracy was an integral part.
    Firearms Crime
    Federal law punishes persons for using or carrying a gun
    "during and in relation to any . . . drug trafficking crime" or
    possessing a gun "in furtherance of any such crime."                      
    18 U.S.C. § 924
    (c)(1)(A); see also United States v. Gonsalves, 
    859 F.3d 95
    ,
    111 (1st Cir. 2017) (explaining that to secure a conviction under
    the   statute,     the    government     must    show   that       the    defendant
    "(1) possessed      a    firearm   (2)   in    furtherance    of    (3)    a    drug-
    trafficking crime").        To satisfy the in-furtherance requirement,
    the government must establish "a sufficient nexus between the
    - 23 -
    firearm and the drug crime such that the firearm advances or
    promotes the drug crime."           United States v. Gurka, 
    605 F.3d 40
    , 44
    (1st Cir. 2010) (quotation marks omitted).
    Rodríguez-Torres and Guerrero-Castro insist that the
    prosecution put forward no evidence showing that they used or
    carried a firearm in furtherance of drug trafficking.                   Ergo, their
    argument continues, the judge should have entered verdicts of
    acquittal on the firearm charge.                The government, for its part,
    believes the opposite is true.             And we, for our part, again side
    with the government.
    Cooperator    Delgado-Pabón         testified     that        Rodríguez-
    Torres   owned      drug   points    in   housing    projects     that       La    Rompe
    controlled.      He testified too that Rodríguez-Torres served as an
    armed enforcer, carrying a .10 caliber Glock — among other duties,
    an   enforcer       "intimidat[ed]"       and    "kill[ed]"     people       for     the
    organization.         Anyway,    cooperator       Calviño-Acevedo       added       that
    Rodríguez-Torres supplied guns to La Rompe and kept a .40 caliber
    Glock    at   his    (Rodríguez-Torres's)         house,    where      he    "decked"
    marijuana     ("decked"     is   slang    for    prepared   for     distribution).
    Shifting from Rodríguez-Torres, Delgado-Pabón testified that he
    saw an always-armed Guerrero-Castro at a La Rompe-controlled drug
    point, pretty much daily at one point.                 Add to this the large
    amount of evidence showing that La Rompe's aim was to defend its
    - 24 -
    drug turf, with violence if necessary, and we conclude that a
    rational jury could easily find that the guns Rodríguez-Torres and
    Calviño-Acevedo carried, and the guns Rodríguez-Torres gave to La
    Rompe,    "advance[d]        or    promote[d]"    their     own    and   their
    coconspirators' drug-dealing business.           See Gurka, 
    605 F.3d at 44
    ;
    see also Ramírez-Rivera, 800 F.3d at 23 (reaching a similar
    conclusion in a similar case involving similar evidence).
    Rodríguez-Torres's and Guerrero-Castro's counterarguments do
    not do the trick either.          Rodríguez-Torres, for example, seemingly
    questions       Delgado-Pabón's      and   Calviño-Acevedo's      credibility,
    calling        their     testimony     occasionally    contradictory        and
    uncorroborated.          What he overlooks is that we must draw all
    inferences — including inferences about credibility — in favor of
    the jury's verdict.         So to the extent that his counterargument
    turns    on    showing    Delgado-Pabón    and   Calviño-Acevedo     were   not
    credible — an issue the jury resolved against them — it fails.
    Also damaging to him is that our sufficiency cases say that
    "[t]estimony from just one witness can support a conviction."
    United States v. Negrón-Sostre, 
    790 F.3d 295
    , 307 (1st Cir. 2015)
    (quotation marks omitted).           As for Guerrero-Castro, he contends
    that Delgado-Pabón did not describe "the type" of gun he (Guerrero-
    Castro) carried at the drug points.              But no such evidence was
    needed.       See Ramírez-Rivera, 800 F.3d at 23.         Still searching for
    - 25 -
    a   game-changing   theory,   he    speculates    that    maybe    he   had   a
    "[r]eplica" gun.     A problem for him is that he approaches the
    record the wrong way — for after drawing all plausible inferences
    in favor of the verdict (something he does not do), we think a
    reasonable jury could infer from the evidence (e.g., that he was
    an "always armed" drug-point owner who "would kill") that he
    possessed a firearm as defined in the criminal code. See 18 U.S.C.
    921(a)(3) (explaining that "firearm" in § 924(c) means a weapon
    "which will or is designed to or may readily be converted to expel
    a projectile by the action of an explosive").8
    Wrap Up
    Sufficiency challenges are notoriously difficult to win,
    given the standard of review.         See, e.g., United States v. Tum,
    
    707 F.3d 68
    , 69 (1st Cir. 2013).             And having spied no winning
    argument here, we press on.
    OUT-OF-COURT-STATEMENTS CLAIMS
    Overview
    Guerrero-Castro    argues     that    the     judge    slipped     by
    admitting two out-of-court statements allegedly made by him — one
    8The indictment also charged the duo with aiding and abetting
    the possession of a firearm in relation to a drug-trafficking
    conspiracy. And Rodríguez-Torres claims the evidence inadequately
    supported that theory.     But because the evidence sufficed to
    convict him as a principal, we need not address that facet of his
    sufficiency claim.
    - 26 -
    to cooperator Calviño-Ramos, the other to cooperator Calviño-
    Acevedo.          Both   statements    indicated   that   Guerrero-Castro     had
    choked a La ONU member to death.             As he sees it, the government
    violated federal Criminal Rule 12 by not notifying him of its plan
    to use these statements at trial.9              Disagreeing, the government
    asserts that Guerrero-Castro "waived" any problem he had with the
    admission of Calviño-Ramos's testimony by not raising it below.
    Waiver aside, the government sees no error because Guerrero-Castro
    made       that   statement   before   Calviño-Ramos      became   a   government
    cooperator and so was not discoverable under Rule 12.                  As for the
    statement to Calviño-Acevedo, the government relevantly contends
    that Guerrero-Castro cannot show prejudice, because the jury had
    already heard Calviño-Ramos's testimony. In the pages that follow,
    9   Rule 12(b)(4)(B) provides that
    [a]t   the  arraignment   or  as   soon  afterward   as
    practicable, the defendant may, in order to have an
    opportunity to move to suppress evidence under Rule
    12(b)(3)(C), request notice of the government's intent
    to use (in its evidence-in-chief at trial) any evidence
    that the defendant may be entitled to discover under
    Rule 16.
    And federal Criminal Rule 16(a)(1)(A) says that
    [u]pon a defendant's request, the government must
    disclose to the defendant the substance of any relevant
    oral statement made by the defendant, before or after
    arrest, in response to interrogation by a person the
    defendant knew was a government agent if the government
    intends to use the statement at trial.
    - 27 -
    we explain why the government has the better of the argument — but
    first, some context.
    A couple of weeks before trial, Guerrero-Castro asked
    the judge to have prosecutors disclose pretrial all statements he
    was entitled to under federal Criminal Rule 16(a)(1)(A) — a
    provision (we note again) that makes discoverable "the substance
    of any relevant oral statement made by the defendant, before or
    after       arrest,   in   response   to    interrogation      by   a   person   the
    defendant knew was a government agent if the government intends to
    use the statement at trial."               Guerrero-Castro wanted to know if
    prosecutors planned to "rely on any such statements" so he could
    decide if he should move to suppress them.                  The judge issued a
    minute order granting Guerrero-Castro's "Rule 16" motion.                    A few
    days    later,    complying    with   a     previous   order    requiring    early
    disclosure of witness statements covered by the Jencks Act, 
    18 U.S.C. § 3500
    , the government handed the defense "4,000 pages" of
    materials relating to cooperators Yanyoré-Pizarro, Delgado-Pabón,
    Calviño-Ramos, and Calviño-Acevedo.10
    At trial, Calviño-Ramos testified that Guerrero-Castro
    got a drug point at "Los Laureles" by "kill[ing]" for La Rompe.
    10
    The Jencks Act is named after Jencks v. United States, 
    353 U.S. 657
     (1957). See United States v. Acosta-Colón, 
    741 F.3d 179
    ,
    189 n.1 (1st Cir. 2013).
    - 28 -
    Asked how he knew this, Calviño-Ramos testified (over leading-
    question and asked-and-answered objections by the defense) that
    Guerrero-Castro, "Bin La[den]," "Bryan Naris," and "Kiki Naranja"
    told him in "Los Laureles" that Guerrero-Castro had choked a La
    ONU member to death.         At a bench conference after Calviño-Ramos's
    testimony, Guerrero-Castro's counsel raised a "Jencks" concern,
    saying he needed any Jencks statements about the choking incident
    for cross-examination purposes.           No such statements existed, the
    prosecutor    told     the   judge.      The   prosecutor   added     that    the
    government had disclosed in pretrial plea negotiations that it
    would put on evidence that Guerrero-Castro had committed a choking
    murder.   And after the judge said "[l]et's proceed with cross,"
    Guerrero-Castro's lawyer said that he had "no issue then."
    Several     days   later,    Calviño-Acevedo       testified    that
    Guerrero-Castro "is known as a person who grabs people by the neck
    and chokes them."        Asked how he knew this, Calviño-Acevedo said
    that Guerrero-Castro "confessed . . . one time" when "we were at
    MDC"   Guaynabo,     a   federal      prison   in   Guaynabo,    Puerto     Rico.
    Guerrero-Castro's counsel objected.            And another bench conference
    took place.    Guerrero-Castro's lawyer noted that "[t]he government
    informed me of the statement that you heard."               But he said that
    the government had not given "written notice" that it intended to
    introduce the statement as "a confession." Responding to questions
    - 29 -
    from the judge, the prosecutor said that Guerrero-Castro's counsel
    knew from "several proffer sessions that evidence would come out
    that his client would choke people, that our cooperating witnesses
    would say in open court under oath that his client would choke
    people, so he knew this was coming."             Asked by the judge if the
    government had told the defense that "this evidence was coming out
    today?"   the     prosecutor   responded       (without   contradiction    from
    defense counsel) that he had.             The prosecutor also said that
    Calviño-Acevedo's comment involved the same choking incident that
    Calviño-Ramos had testified to.           Finding that the government had
    given the defense "plenty of notice" and that Calviño-Acevedo would
    simply    be    "confirming    what   [Calviño-Ramos]      said,"   the   judge
    overruled the objection.
    Now on to our take.
    Analysis
    Standard of Review
    Abuse-of-discretion review applies to preserved claims
    that the judge should not have admitted evidence because the
    government infracted Rule 12. See, e.g., United States v. Marrero-
    Ortiz, 
    160 F.3d 768
    , 774 (1st Cir. 1998).             The parties, however,
    disagree on whether Guerrero-Castro properly preserved all his
    arguments here.      Guerrero-Castro says he did.         The government says
    he is only half right, insisting that he waived or forfeited his
    - 30 -
    arguments about Calviño-Ramos's testimony but agreeing that he
    preserved his arguments about Calviño-Acevedo's testimony.                        We
    bypass    any   concerns     about   waiver     or   forfeiture,      because   his
    challenge fails regardless.
    Statement to Calviño-Ramos
    Rule     12(b)(4)(B)       applies       to    evidence      that     is
    "discoverable under Rule 16." United States v. de la Cruz-Paulino,
    
    61 F.3d 986
    , 993 (1st Cir. 1995).              To be discoverable under Rule
    16, the statement had to have been made to a government agent.
    Fed. R. Crim. P. 16(a)(1)(A).          But Guerrero-Castro offers no Rule
    16-based argument — i.e., that he made the statement "in response
    to interrogation by a person [he] knew was a government agent."
    And that is probably because — as the government notes, without
    being    contradicted       (Guerrero-Castro     filed     no   reply    brief)   —
    Guerrero-Castro      made     the    statement       to   Calviño-Ramos     before
    Calviño-Ramos      became    a   government     cooperator.       See    generally
    United States v. Taylor, 
    417 F.3d 1176
    , 1181 (11th Cir. 2005)
    (spying    no   abused      discretion   "in     admitting"     the     challenged
    testimony because the defendant "made . . . voluntary statements
    to an individual who was not a government agent" — thus "the
    statements are . . . not discoverable under" Rule 16(a)(1)(A)).
    - 31 -
    Statement to Calviño-Acevedo
    We   can    also   make    quick    work    of   Guerrero-Castro's
    challenge to Calviño-Acevedo's testimony.            That is because even if
    Guerrero-Castro could show a Rule 12 violation (and we intimate no
    hint of a suggestion that he could), he cannot show prejudice,
    because the jury had already heard Calviño-Ramos's testimony to
    the same effect.     See generally de la Cruz-Paulino, 
    61 F.3d at 993
    (noting that to get a reversal for a Rule 12 violation, "[a]
    defendant must prove that the alleged violation prejudiced his
    case" (quotation marks omitted and brackets in original)).               And
    despite hearing both Calviño-Ramos and Calviño-Acevedo testify
    about the choking admission, the jury found Guerrero-Castro not
    guilty of two murder counts — this fact is significant, because a
    "discriminating verdict . . . tends to" undercut an "assertion of
    prejudice."    United States v. Tashjian, 
    660 F.2d 829
    , 836 (1st
    Cir. 1981); accord United States v. Boylan, 
    898 F.2d 230
    , 246 (1st
    Cir. 1990).
    Wrap Up
    Guerrero-Castro's Rule 12 complaint is not the stuff of
    reversible error.

    JURY-INSTRUCTION CLAIMS
    Overview
    Each defendant challenges various parts of the judge's
    general RICO-conspiracy instructions.11       Here is what you need to
    know.
    After the government concluded its case-in-chief, the
    judge excused the jury and handed counsel a "draft" of the proposed
    jury instructions so that they could "take [the draft] with" them
    that night.    The judge warned them to "be prepared to do closings"
    the following day.
    The next morning, the judge discussed with counsel a few
    tweaks he made to the draft instructions (adding, for example,
    conspiracy-withdrawal and multiple-conspiracy instructions).        The
    defendants     completed   their    cases   that   morning   (Rodríguez-
    Martínez's mother took the stand, for instance) and then rested.
    Before breaking for lunch at 12:45 p.m., the judge distributed the
    revised instructions.
    11
    To save the reader from having to flip back a few pages,
    we repeat that RICO forbids "person[s] employed by or associated
    with any enterprise engaged in, or the activities of which affect,
    interstate or foreign commerce, to conduct or participate,
    directly or indirectly, in the conduct of [that] enterprise's
    affairs through a pattern of racketeering activity" — or to
    conspire to do so. See 
    18 U.S.C. § 1962
    (c), (d).
    - 33 -
    At around 2:00 p.m., the court came back into session.
    The   government,     Guerrero-Castro,       and    Vigio-Aponte       gave   their
    closing arguments.        And Rodríguez-Martínez started his.                 After
    excusing the jury for the evening, the judge asked counsel if they
    had "[a]ny questions about the instructions."                    Speaking first,
    Guerrero-Castro's lawyer said that he had "reviewed" the draft
    instructions, "checked some cases," and made written "notes" about
    "questions or suggestions." He then asked for a couple of changes.
    But concerning the RICO instructions, he only objected to what the
    parties (and we) call the "essence of a RICO conspiracy" charge
    (representing the judge's summary of RICO law), arguing that "it's
    repetitive, because the elements have been discussed in detail in
    the prior instructions" and that it unduly "simplifie[s] . . . the
    elements that have to be proven beyond a reasonable doubt."
    Sánchez-Mora's counsel joined in that objection.                      Counsel for
    Rodríguez-Torres, Rodríguez-Martínez, and Vigio-Aponte raised no
    objections    to    the   RICO-conspiracy         instructions.        The    judge
    declined to eliminate the essence-of-a-RICO-conspiracy charge.
    The   following       day,   after   the    remaining    defendants'
    closing arguments and the government's rebuttal, the judge charged
    the jury.     On the RICO-conspiracy count, the judge said that to
    establish guilt, "the government must prove that each defendant
    knowingly    agreed    that    a    conspirator,        which   may   include   the
    - 34 -
    defendant himself, would commit a violation of . . . 18 U.S.[C. §]
    1962(c), which is commonly referred to as the substantive RICO
    [s]tatute."     After quoting § 1962(c), the judge stated (emphasis
    ours) that the government must prove five elements beyond a
    reasonable doubt:
    First, that an enterprise existed or that [an]
    enterprise would exist. Second, that the enterprise was
    or would be engaged in or its activities [a]ffected or
    would [a]ffect interstate or foreign commerce. . . .
    Third, that a conspirator was or would be employed or
    associated with the enterprise.        Fourth, that a
    conspirator did or would conduct or participate in —
    either directly or indirectly — the conduct of the
    affairs of the enterprise.        And, fifth, that a
    conspirator did or would knowingly participate in the
    conduct of the affairs of the enterprise through a
    pattern of racketeering activity as described in the
    Indictment. That is, a conspirator did or would commit
    at least two acts of racketeering activity.
    The judge then said a little bit about each element.              For example,
    and   as   relevant   here,    the   judge     said   (emphasis    ours)   that
    "racketeering    activity"     includes       "drug   trafficking,   robbery,
    murder,    carjacking,   and   illegal    use    of   firearms,    among   many
    others."   And then the judge gave the essence-of-a-RICO-conspiracy
    charge (again, emphasis ours):
    [B]ecause the essence of a RICO conspiracy offense is
    the agreement to commit a substantive RICO offense, the
    government need only prove beyond a reasonable doubt
    that if the conspiracy offense was completed as
    contemplated, the enterprise would exist, that this
    enterprise would engage in or its activities would
    [a]ffect interstate or foreign commerce[,] [a]nd that a
    conspirator, who could be but need not be the defendant
    himself, would have been employed by or associated with
    - 35 -
    the enterprise   through    a    pattern   of   racketeering
    activity.
    The government is not required to prove that the
    alleged enterprise was actually established; that the
    defendant was actually employed by or associated with
    the enterprise; or that the enterprise was actually
    engaged in or its activities actually [a]ffected
    interstate or foreign commerce.
    Wrapping up, the judge explained what the government had to
    establish to show that a defendant "entered into the required
    conspiratorial agreement" — namely, "that the conspiracy existed
    and that the defendant knowingly participated in the conspiracy
    with the intent to accomplish [its] objectives or assist other
    conspirators in accomplishing [its] objectives," with knowingly
    "mean[ing] that something was done voluntarily and intentionally,
    and not because of a mistake, accident or other innocent reason."
    After completing the charge, the judge gave the lawyers
    a chance to object at sidebar.       Only Guerrero-Castro's attorney
    objected to the RICO-conspiracy instructions, repeating his claim
    that the essence-of-a-RICO-conspiracy charge "oversimplifies the
    elements of the offense."
    With this background in place, we flesh out the parties'
    claims.
    Our defendants argue — in various combinations — that
    the judge gave improper and confusing RICO-conspiracy instructions
    - 36 -
    (in delivering both the long version and the essence-of-a-RICO-
    conspiracy charge) by
    (1)   not requiring findings that (a) the enterprise actually
    existed; (b)the enterprise actually affected interstate
    or foreign commerce; (c) the defendant actually was
    employed or associated with the enterprise; and (d) the
    defendant actually participated in the conduct of the
    enterprise's affairs;
    (2)   not saying that a defendant must have "knowingly joined"
    the RICO conspiracy; and
    (3)   stating that a firearms crime constitutes racketeering
    activity.
    For ease of reference, we will call these — perhaps somewhat
    unimaginatively — argument (1), argument (2), and argument (3).
    Anyhow, their argument (1) theory is that the judge's
    repeated use of "would" — that "the enterprise would exist," that
    the enterprise's "activities would [a]ffect interstate or foreign
    commerce," etc. (emphasis ours) — clashes with Ramírez-Rivera,
    where we said that a RICO-conspiracy conviction requires that the
    government establish
    the existence of an enterprise affecting interstate [or
    foreign] commerce[;] . . . that the defendant knowingly
    joined the conspiracy to participate in the conduct of
    the affairs of the enterprise[;] . . . that the defendant
    participated in the conduct of the affairs of the
    enterprise[;] and . . . that the defendant did so through
    a pattern of racketeering activity by agreeing to
    commit, or in fact committing, two or more predicate
    offenses.
    800 F.3d at 18 (alteration in original) (quoting United States v.
    Shifman,   
    124 F.3d 31
    ,   35   (1st   Cir.   1997)).   Their   argument
    - 37 -
    (2) claim is that given cases like Ramírez-Rivera, the judge had
    to — but did not — tell jurors that to convict on a RICO-conspiracy
    charge, they must find that each defendant knowingly joined the
    conspiracy.      And their argument (3) contention relies on United
    States v. Latorre-Cacho, where we held that a judge erred by
    instructing the jury that "'firearms' constitute 'racketeering
    activity'" — the rationale being that "the commission of firearms
    offenses, or even the involvement with firearms," is not included
    in the statutory definition of "racketeering activity."                 
    874 F.3d 299
    , 301, 302 (1st Cir. 2017).
    Responding to argument (1), the government claims that
    the   judge    correctly     and   clearly    instructed   the   jury    on   the
    enterprise, interstate-commerce, association, and participation
    elements of the RICO-conspiracy crime.            "[T]his [c]ourt," writes
    the   government,     "has     not   decided    whether"    RICO   conspiracy
    "requires proof of an existing enterprise; and the Supreme Court,
    though describing the nature of a RICO conspiracy in terms that
    foreclose such a requirement, has not explicitly decided the
    question" either — "[t]he same is true" of the other contested
    elements, the government adds.         So in the government's view (based
    mainly on its reading of the tea leaves in the United States
    Report), the prosecution can satisfy "its burden by proving that
    the conspirators agreed to           form    an enterprise" — which, the
    - 38 -
    government argues, undercuts the defendants' "interstate-commerce,
    association, and participation" arguments as well. As for Ramírez-
    Rivera,    the   government    calls   the   passage   excerpted   above   —
    requiring "the existence of an enterprise," for instance — "dicta,"
    because prosecutors there, "like th[e] one[s]" here, "relied on
    evidence    of   an   actual   racketeering    enterprise    to   prove   the
    agreement that one would be established, and no argument was raised
    [there] that the existence of an enterprise was not a necessary
    element" of a RICO-conspiracy offense.
    As for argument (2), the government insists that the
    judge's instructions — e.g., "that the conspiracy existed and that
    the defendant knowingly participated in the conspiracy with the
    intent to accomplish [its] objectives or assist other conspirators
    in accomplishing [its] objectives" — made clear that the defendants
    had to have knowingly joined the conspiracy.           Which means that the
    government believes the judge gave error-free instructions on
    these matters — though the government does argue that even if the
    judge did err, the defendants still lose, because they cannot show
    "prejudice" or "a miscarriage of justice."
    Moving to argument (3), the government admits that,
    given Latorre-Cacho, the judge did err in telling the jury that a
    firearms crime is a racketeering activity for RICO-conspiracy
    purposes.    But, the government assures us, we need not reverse on
    - 39 -
    this issue, because no challenging defendant can show "prejudice
    []or a miscarriage of justice," given the "strength of the . . .
    evidence of more than two qualifying predicate acts."
    Time for us to explain why no reversal is called for
    here.
    Analysis
    Standard of Review
    Conceding    that     they   did   not   preserve   their    jury-
    instruction arguments, Rodríguez-Torres, Sánchez-Mora, Rodríguez-
    Martínez, and Vigio-Aponte admit that they now must satisfy the
    demanding plain-error standard, showing not just error but error
    that is obvious, that is prejudicial (meaning it affected the
    proceeding's outcome), and that if not fixed by us (exercising our
    discretion) would cause a miscarriage of justice or undermine
    confidence       in   the    judicial       system.      See,   e.g.,      Rivera-
    Carrasquillo, 933 F.3d at 48 n.14.
    Desperate to escape plain-error review, Guerrero-Castro
    says    that    he    did   object    to    the   judge's   essence-of-a-RICO-
    conspiracy charge.          True, but that does not help him.                 His
    arguments below (that the essence charge was repetitive of the
    previous instructions that stated "the elements" and was also too
    simplified to boot) are different from his arguments here (that
    the instructions did not accurately define the RICO elements, for
    - 40 -
    the reasons described in arguments (1) and (2), above — a/k/a, the
    "would"-related-instruction          and      the       knowledge-instruction
    claims).   And our caselaw says that a timely objection on one
    ground does not preserve an objection on a different ground.                 See
    United States v. Glenn, 
    828 F.2d 855
    , 862 (1st Cir. 1987).
    Undaunted, Guerrero-Castro claims that he should get a
    pass because the judge conferenced with counsel on the instructions
    after the first day of closing arguments, which (supposedly) gave
    his attorney "no time to properly prepare and provide the [judge]
    more detailed objections."     Call us unconvinced.             Not only does he
    cite us no authority to support his free-pass proposition, but the
    record refutes his no-time assertion.           The judge gave counsel the
    proposed instructions two days before he charged the jury; over
    those two days, the judge had several discussions with counsel
    about the instructions, including one in which Guerrero-Castro's
    lawyer   acknowledged   that   he    had     reviewed     and   researched   the
    instructions and asked for some changes; and the judge held a
    sidebar with counsel after delivering the charge, during which
    Guerrero-Castro's   counsel    objected        to   the    essence-of-a-RICO-
    conspiracy charge, but, again, not on the grounds raised here.
    See United States v. Henry, 
    848 F.3d 1
    , 13-14 (1st Cir. 2017)
    (finding an instructional claim not preserved because counsel did
    not raise it at the post-charge sidebar).
    - 41 -
    The net result is that we apply plain-error review to
    these challenges, knowing too that unpreserved claims of error
    like these "rare[ly]" survive plain-error analysis.          See Henderson
    v. Kibbe, 
    431 U.S. 145
    , 154 (1977) (emphasis added); accord United
    States v. Gómez, 
    255 F.3d 31
    , 37 (1st Cir. 2001) (stressing that
    "the plain-error exception is cold comfort to most defendants
    pursuing   claims    of   instructional   error");    United    States   v.
    Paniagua-Ramos, 
    251 F.3d 242
    , 246 (1st Cir. 2001) (noting that
    "the plain error hurdle, high in all events, nowhere looms larger
    than in the context of alleged instructional errors").
    Argument (1)
    Even     assuming   (without   deciding)   that     the   judge's
    "would"-related instructions — that "the enterprise would exist,"
    that the enterprise's "activities would [a]ffect interstate or
    foreign commerce," etc. (emphasis added) — amount to an error that
    is also obvious (and to be perfectly clear, we intimate no judgment
    on those questions), we conclude that the defendants fail to
    establish prejudice or a miscarriage of justice.12
    If an instruction leaves out an offense element, that
    "alone is insufficient to demonstrate prejudice."            United States
    12This is as good a place as any to say a few words about the
    parties' views on Ramírez-Rivera. As noted, the defendants read
    Ramírez-Rivera as holding that prosecutors in a RICO-conspiracy
    case must prove that the enterprise actually existed, that the
    defendant was actually employed by or associated with the
    - 42 -
    v. Hebshie, 
    549 F.3d 30
    , 44 (1st Cir. 2008) (emphasis added).13
    Rather, a defendant "must satisfy the difficult standard of showing
    a likely effect on the outcome or verdict."         
    Id.
     (quotation marks
    omitted).   And this our defendants have not done.
    The   government   charged    an   actual   enterprise.    And
    prosecutors presented that theory to the jury in its opening
    statement, closing summation, and rebuttal argument.              "Power,
    money, control," the prosecution's opening statement began.           "The
    means[:]    drug trafficking, robberies, carjackings, shootings,
    violence, murder" — "[t]hat was the business of La Rompe . . .,
    and that is what this case is about."              In its closing, the
    enterprise, that the enterprise's activities actually affected
    interstate or foreign commerce, and that the defendant actually
    participated in the enterprise's affairs. But as the government
    correctly states, Ramírez-Rivera did not have to confront that
    issue, because prosecutors there relied on evidence of the
    enterprise's actual existence, the defendant's actual employment
    or association with the enterprise, etc., to prove the RICO-
    conspiracy charge. See 800 F.3d at 18-21. As the government also
    correctly states, no binding precedent exists on this issue. And
    we need not stake out a position on these points today, because
    (as we explain in the text) the defendants lose on plain-error
    review even if their view is correct (and we, of course, whisper
    no hint that it is). See generally United States v. Caraballo-
    Rodríguez, 
    480 F.3d 62
    , 70 (1st Cir. 2007) (explaining that a
    holding that a party "has not met his burden of showing there was
    an error which was plain" is not a "ruling on the merits").
    13 As the government explains, the assumed errors here are
    perhaps better described as "misdescription[s] of . . . element[s]"
    rather than omissions.    See Johnson v. United States, 
    520 U.S. 461
    , 469 (1997). But the defendants offer no reason (and we see
    none) for why this distinction should matter for our analysis.

    prosecution stressed that "La Rompe was a violent gang that
    controlled the drug trafficking activities in more than 18 areas,
    including housing projects and wards within the Municipalit[ies]
    of San Juan, Carolina, and Trujillo Alto," with its "enem[y]" being
    "La ONU."    The prosecution also called La Rompe "[a]n organization
    that killed" in its rebuttal — "[a]n organization that [killed] to
    become more powerful[,] [f]or control, power, money."
    And   the     government      presented   overwhelming     evidence
    (which we spotlighted pages ago) to back up its theory.                     For
    example, the evidence showed that La Rompe actually existed as an
    enterprise, given how associates:               self-identified as La Rompe
    members; had meetings to discuss matters that affected La Rompe;
    shared resources, including manpower, guns, and cars; got together
    every day to peddle monstrous amounts of drugs at La Rompe's many
    drug points; committed robberies, carjackings, and murder in La
    Rompe's name; and had to follow strict rules of conduct, on pain
    of death.    The evidence also showed that La Rompe's actions had at
    least a de minimis effect on interstate or foreign commerce, seeing
    how (among other things) La Rompe imported cocaine and heroin from
    South America.     As for participation, the evidence showed that the
    defendants    owned      drug     points   in   La   Rompe-controlled   housing
    projects.      And    on    the    pattern-of-racketeering     question,    the
    evidence showed that La Rompe members — leaders, drug-point owners,
    - 44 -
    runners, and sellers, etc. — actually committed (or aided and
    abetted the commission of) countless drug sales and scores of
    murders, all to advance the enterprise's ghastly business.
    In their presentations to the jury, even defense counsel
    did not dispute that La Rompe existed, affected interstate or
    foreign    commerce,    and     conducted     its     affairs    through    drug-
    trafficking     and   murder.     For   example,      Vigio-Aponte's       counsel
    predicted in her opening statement that the evidence would show
    that   some    of   Yanyoré-Pizarro's       murders    were     (emphasis   ours)
    "related to the La Rompe . . . organization."                    In his closing
    argument, Guerrero-Castro's attorney called La Rompe "a clan of
    killers" that operated through "a whole bunch of leaders . . .[,]
    runners, and sellers, and drug point owners." Vigo-Aponte's lawyer
    admitted in her closing that La Rompe had "area[s]."                 Rodríguez-
    Martínez's attorney conceded in his closing that his client's
    cousin was a La Rompe member (implicitly acknowledging that La
    Rompe does exist).       And summarizing — without contesting — the
    cooperators' testimony about how La Rompe's drug operation worked,
    Sánchez-Mora's counsel noted in his closing that
    [t]here are leaders in different housing projects, and
    . . . these leaders appoint people to become drug point
    owner[s]. . . . [T]he person that becomes a drug point
    owner has basically proven [his] worth to the
    organization, and that's by killing someone. The person
    that kills on behalf of the organization, proves . . .
    [his] loyalty.
    - 45 -
    No surprise, then, that defendants cannot show that the
    "would"-related instructions — that "the enterprise would exist,"
    that the enterprise's "activities would [a]ffect interstate or
    foreign commerce," etc. (emphasis added, and apologies for the
    repetition) — prejudiced them or caused a miscarriage of justice.
    See Hebshie, 
    549 F.3d at
    44-45 & n.14 (holding that (a) the
    defendant   did   not     show   prejudice    from   an   instruction   that
    "eliminated an element of the crime," because the government
    provided "strong" evidence of the omitted element and defense
    counsel failed to contest that evidence; and that (b) even if the
    defendant had shown prejudice, the omission did not cause a
    miscarriage of justice, "[b]ecause the evidence was not closely
    contested and [was] sufficient to support [his] conviction").
    Rodríguez-Torres,       Sánchez-Mora,   and    Vigio-Aponte    claim    that
    "insofar    as"   their   "conviction[s]"     are    "based   on   erroneous
    elements," that in itself is enough to show prejudice and a
    miscarriage of justice.      But this argument conflicts with settled
    law.   See 
    id. at 44
     (explaining that "[t]he mere fact that an
    erroneous instruction resulted in the omission of an element of
    the offense is not alone sufficient to demonstrate a prejudicial
    [e]ffect on the outcome of the trial"); see also Johnson, 
    520 U.S. at 470
     (noting that (a) if an instruction omitting an offense
    element did not affect the judgment, it "would be the reversal of
    - 46 -
    [such] a conviction" that would seriously affect the fairness,
    integrity, and public reputation of judicial proceedings, thereby
    causing a miscarriage of justice; and that (b) "[r]eversal of
    error,    regardless      of   its     effect   on    the   judgment,      encourages
    litigants to abuse the judicial process and bestirs the public to
    ridicule     it"    (emphasis        added   and     internal       quotation    marks
    omitted)). Rodríguez-Martínez makes no effort to show prejudice.14
    And he wrongly argues that a misinstruction automatically causes
    a miscarriage of justice.              As for Guerrero-Castro, he makes no
    attempt to show either prejudice or a miscarriage of justice.                       All
    of   which    devastate        their     plain-error        bids.      See      Rivera-
    Carrasquillo, 933 F.3d at 49; see also United States v. Gordon,
    
    875 F.3d 26
    , 30 (1st Cir. 2017) (stressing that "[t]he party
    asserting    that    an   error was       plain      must   carry    the   burden   of
    establishing that the claimed error satisfies each element of this
    standard"); United States v. Ponzo, 
    853 F.3d 558
    , 586 (1st Cir.
    2017) (deeming an argument waived because defendant made no effort
    to meet each part of the plain-error test).15
    14 To the extent Rodríguez-Martínez tries to fix this by
    mentioning prejudice and miscarriage of justice in his reply brief,
    his effort comes too late. See, e.g., United States v. Marino,
    
    833 F.3d 1
    , 6 n.3 (1st Cir. 2016) (stressing that an argument
    introduced in a reply brief is waived).
    15Rodríguez-Torres, Sánchez-Mora, and Vigio-Aponte label the
    instructions generally confusing. But they offer no miscarriage-
    - 47 -
    Argument (2)
    We shift then to argument (2), involving the knowledge-
    instruction claim.       Recall that the judge (among other things)
    told the jury that the government had to prove that "the defendant
    knowingly    participated    in    the     conspiracy   with    the   intent   to
    accomplish    [its]    objectives     or    assist   other     conspirators    in
    accomplishing [its] objectives," with knowingly "mean[ing] that
    something was done voluntarily and intentionally, and not because
    of a mistake, accident or other innocent reason."                We need not —
    and thus do not — decide whether the judge committed an error that
    is plain here, because even if defendants could show error and
    plainness (and we do not suggest that they can), they have not
    shown prejudice or a miscarriage of justice.            Each defendant owned
    a drug point.         And because "drug-point ownership was a vital
    component" of the "conspiracy, given that the whole point of the
    enterprise was to maintain control of as many drug points as
    possible to earn more money," we easily conclude that "the jury
    had abundant evidence to find that the [d]efendants were integral
    parts of the enterprise's activities," see Ramírez-Rivera, 800
    F.3d at 20 — evidence that satisfies the "knowledge" element too,
    see id. at 18 n.11.      So the supposed instructional error could not
    of-justice argument — which dashes their hopes for a reversal on
    that basis. See, e.g., Ponzo, 853 F.3d at 586.
    - 48 -
    have changed the outcome.    See United States v. O'Brien, 
    435 F.3d 36
    , 40 (1st Cir. 2006) (explaining that "it is enough to sustain
    the conviction that the result would quite likely have been the
    same" despite the off-target instruction).
    Apparently    forgetting    about   Johnson    and   Hebshie,
    Rodríguez-Torres, Sánchez-Mora, and Vigio-Aponte try to head off
    this conclusion by again wrongly asserting that misinstruction
    necessarily prejudices a defendant.        Rodríguez-Torres, Sánchez-
    Mora, and Guerrero-Castro also call the evidence of their knowingly
    joining the conspiracy "weak" — an assertion we have already
    disposed of.
    But even if they could show prejudice (which, again,
    they cannot), they have not shown that their convictions caused a
    miscarriage of justice.      That is so because they rely on the
    already-rejected argument that a verdict based on an instructional
    error automatically constitutes a miscarriage of justice.
    Argument (3)
    Given    Latorre-Cacho,    Rodríguez-Torres,   Sánchez-Mora,
    Vigio-Aponte, and Guerrero-Castro have shown that the instruction
    about a firearms crime being a RICO predicate is both error and
    obviously so.16   But even if we assume (without granting) that they
    16Latorre-Cacho came down years after our defendants' trial.
    But plain error's "error and plainness" requirements "are judged
    - 49 -
    can also show prejudice, they still must prove a miscarriage of
    justice.    And unfortunately for them, they have not.
    Noting that only two predicates are needed to support a
    RICO-conspiracy conviction, the government sees no miscarriage of
    justice.    According to the government, "because it was undisputed
    that the La Rompe conspiracy comprised" many instances of "drug-
    trafficking and murder, the jury necessarily would have found those
    predicates."     For their part, and as the government also notes,
    the   challenging      defendants    base     their     miscarriage-of-justice
    argument    entirely    on   the    false    premise    that   a   jury's   being
    "misinstructed    as    to   an    element   of   the    offense"    necessarily
    "cast[s] doubt [on] the integrity and fairness of a judicial
    process."    We say "false" because, as we have been at pains to
    explain, Johnson and Hebshie reject that premise.17                And by failing
    as of the time of appeal." United States v. Torres-Rosario, 
    658 F.3d 110
    , 116 (1st Cir. 2011).
    17Latorre-Cacho does not help their miscarriage-of-justice
    theory either. Because the evidence of the proper predicates there
    — drug trafficking, robbery, and carjacking — was not
    "overwhelming"   (for   example,   the   Latorre-Cacho   defendant
    testified, contesting any ties to the alleged predicate acts), we
    could "not see how [the miscarriage-of-justice] prong of the plain
    error standard precludes [him] from demonstrating plain error,"
    especially since prosecutors waived any argument that might have
    refuted his miscarriage-of-justice theory. See 874 F.3d at 311.
    Two things distinguish Latorre-Cacho from our case. Here, unlike
    there, the evidence of the proper predicates — drug selling and
    murder (discussed in addressing argument (1), which recaps info
    discussed in addressing the sufficiency claims) — was overwhelming
    (or at least our defendants make no effort to show a lack of
    - 50 -
    on the miscarriage-of-justice front, defendants' argument (3)
    contentions come to naught.         See, e.g., Ponzo, 853 F.3d at 586.
    Wrap Up
    Having reviewed defendants' instructional-error claims
    with care, we find that none strike home, because they failed to
    satisfy all facets of the plain-error inquiry.
    SENTENCING CLAIMS
    Overview
    Rodríguez-Torres    and   Rodríguez-Martínez      attack     their
    concurrent,       within-guidelines      sentences     as    procedurally      and
    substantively      unreasonable.         The   pertinent     background   is   as
    follows (fyi, given the issues in play, there's no need to get
    into all the sentencing math behind their terms).
    The judge assigned Rodríguez-Torres an offense level of
    43   and   a    criminal-history    category      of   II,   which   yielded     a
    guidelines-sentencing range of life in prison.                  But the judge
    varied downward, sentencing him to concurrent 405-month terms on
    the RICO-conspiracy count, the drug-conspiracy count, and a drive-
    by-shooting count.      The judge later assigned Rodríguez-Martínez an
    offense level of 31 and a criminal-history category of III, which
    overwhelming evidence in pushing their miscarriage-of-justice
    plea). And here, unlike there, prosecutors waived no miscarriage-
    of-justice argument.
    - 51 -
    resulted in a sentencing range of 135-168 months.              And the judge
    sentenced him to concurrent 168-month terms on the RICO-conspiracy
    count and the drug-conspiracy count.
    On the procedural front, Rodríguez-Torres — repeating
    arguments that he made and lost below — insists that the judge
    doubly erred.   He first argues that the judge stumbled by applying
    a   first-degree       murder    cross-reference        specified    in    USSG
    § 2D1.1(d)(1) — a provision that jacks up a defendant's penalty
    range if a person is killed during an offense under circumstances
    that would constitute murder under federal law.              As he tells it,
    the cross-reference should not apply because he lacked the mens
    rea ("guilty mind," in nonlegalese) for first-degree murder, since
    his only involvement in a drive-by shooting (the relevant count of
    conviction here) was to drive the car whose passengers shot and
    killed several persons.              He then argues that the judge also
    blundered by applying a manager/supervisor penalty enhancement
    under USSG § 3B1.1, because — in his view — no evidence showed
    that he actually "supervised any other defendant []or that he had
    sellers, runners, lookouts or any other type of supervision over
    anyone   serving   a    role    in    the   alleged   conspiracy."    As   for
    Rodríguez-Martínez, he contends for the first time that the judge
    procedurally erred by attributing too much marijuana to him, by
    wrongly concluding that his drug activities qualified him for a
    - 52 -
    manager/supervisor penalty enhancement, and by miscalculating his
    criminal history points.18
    Responding to the procedural-reasonableness arguments,
    the government insists that the evidence showed that Rodríguez-
    Torres aided and abetted the premediated killings.    The government
    then says that role-in-the-offense enhancement had no effect on
    his offense level, because his offense level was already at 43 —
    which is the highest offense level allowable under the sentencing
    guidelines.     And the government thinks that Rodríguez-Martínez
    waived his procedural-reasonableness claim by not objecting to the
    calculations in the presentencing report.
    Rodríguez-Torres and Rodríguez-Martínez then argue in
    unison that these procedural flubs caused them to get excessive
    sentences.    To which the government replies that because they are
    merely recycling their failed procedural-reasonableness theories,
    their substantive-reasonableness claims go nowhere too.
    Our reaction is basically the same as the government's.
    18 He also says in a single sentence in his brief that the
    judge "ignored the individualized sentencing required by 
    18 U.S.C. § 3553
    (a)."    But we deem that suggestion waived for lack of
    development. See, e.g., United States v. Zannino, 
    895 F.2d 1
    , 17
    (1st Cir. 1990).
    - 53 -
    Analysis
    Standard of Review
    The standard of review is not without nuance. See, e.g.,
    United States v. Severino-Pacheco, 
    911 F.3d 14
    , 21 (1st Cir. 2018);
    United States v. Pérez, 
    819 F.3d 541
    , 545 (1st Cir. 2016).           But
    for today we need only say that preserved claims of sentencing
    error trigger abuse-of-discretion review.         See, e.g., Pérez, 819
    F.3d at 545.
    Procedural Reasonableness
    Up first is Rodríguez-Torres's mens rea attack on the
    judge's application of the first-degree-murder cross-reference.
    Federal law defines first-degree murder as "the unlawful killing
    of   a   human    being   with     malice     aforethought,"   including
    "premeditated murder."    
    18 U.S.C. § 1111
    (a).       Even a brief moment
    of premeditation suffices.       See United States v. Catalán–Román,
    
    585 F.3d 453
    , 474 (1st Cir. 2009).          Federal law also says that a
    person who aids or abets the commission of a federal crime "is
    punishable as a principal."        
    18 U.S.C. § 2
    .       And for current
    purposes it is enough to say that a person is liable for aiding
    and abetting if he "'consciously shared the principal's knowledge
    of the underlying criminal act, and intended to help the principal'
    accomplish it."   United States v. Iwuala, 
    789 F.3d 1
    , 12 (1st Cir.
    - 54 -
    2015) (quoting United States v. Taylor, 
    54 F.3d 967
    , 975 (1st Cir.
    1995)).
    The evidence here easily proves that Rodríguez-Torres
    aided and abetted the premediated killing of Santos Díaz-Camacho
    (a La Rompe leader who had "turned" on the organization) and his
    escorts.   Rodríguez-Torres drove one of the cars used to carry out
    the drive-by killings.   And it is reasonable to infer that he knew
    about the plan to commit the killings and intended by his actions
    to help make the plan succeed.    We say this because the evidence
    revealed that Rodríguez-Torres arrived at a prearranged meeting
    with Vázquez-Carrasquillo (La Rompe's top leader, who had ordered
    Díaz-Camacho's killing) and a group of armed La Rompe enforcers.
    He then went off with them to "hunt down" Díaz-Camacho.     And he
    helped them at each step, taking some of the posse to Díaz-
    Camacho's housing complex; waiting with them for hours; tailing
    Díaz-Camacho and his escorts to a different location; pulling up
    his car so others could shoot and kill them; and then ditching his
    (Rodríguez-Torres's) car.    Cinching our conclusion is the fact
    that Rodríguez-Torres drove a person who communicated with a La
    Rompe leader to coordinate the group's actions and pass along
    Vázquez-Carrasquillo's orders — so Rodríguez-Torres could have no
    doubt about the group's murderous intentions.
    - 55 -
    Very little need be said about the manager/supervisor
    enhancement, for the simple reason that this enhancement had no
    effect on Rodríguez-Torres's offense level.
    As for Rodríguez-Martínez's procedural-reasonableness
    arguments, we also spend no time on them.      And that is because he
    abandoned them at sentencing, given how his counsel told the judge
    that he agreed with the relevant calculations as the judge reviewed
    them.    See United States v. Ramírez-Negrón, 
    751 F.3d 42
    , 52 (1st
    Cir. 2014) (finding waiver in a similar situation).
    Substantive Reasonableness
    A sentence flunks the substantive-reasonableness test
    only if it falls beyond the expansive "universe of reasonable
    sentencing outcomes."    See United States v. Bermúdez-Meléndez, 
    827 F.3d 160
    , 167 (1st Cir. 2016); see also United States v. Tanco-
    Pizarro, 
    892 F.3d 472
    , 483 (1st Cir. 2018) (noting that "a sentence
    is substantively reasonable if the court's reasoning is plausible
    and the result is defensible").      Rodríguez-Torres and Rodríguez-
    Martínez believe that the judge's procedural errors led him to
    impose    overly-harsh     sentences,    amounting     to    substantive
    unreasonability.     But    having   shown   that    their   procedural-
    reasonableness theories lack oomph, we cannot say that the judge
    acted outside the realm of his broad discretion in handing out the
    within-guidelines sentences.    So their substantive-reasonableness
    - 56 -
    claims are no-gos.   See, e.g., United States v. Madera-Ortiz, 
    637 F.3d 26
    , 30 (1st Cir. 2011).
    Wrap Up
    Concluding,   as   we    do,     that   Rodríguez-Torres's   and
    Rodríguez-Martínez's sentencing challenges lack force, we leave
    their prison terms undisturbed.
    ENDING
    All that is left to say is:         Affirmed.
