                             Before

                 Kayatta, Lynch, and Thompson,

    Juan F. Matos-De Juan for appellant Andino-Rodríguez.
    Tina Schneider for appellant Martínez-Alberto.
     Jonathan E. Jacobson, with whom W. Stephen Muldrow, United

                         August 21, 2023
           THOMPSON, Circuit Judge.     Experience has taught us drugs

are trafficked in many ways, with drug runners using assorted

transportation methods and various concealment techniques to move

their narcotics.    Today's drug-trafficking case comes by sea, via

the Black Wolfpack, a boat that ferried cocaine smugglers and their

product between Caribbean islands.       Specifically, the players in

this scheme undertook voyages from Puerto Rico to St. Thomas to

acquire and package bricks of cocaine for transport back to Puerto

Rico, where they would then receive compensation for their efforts.

That came to an end in January 2018, though, when federal agents

intercepted the Black Wolfpack off the coast of St. Thomas and,

with it, four of the trafficking enterprise's participants.

           What resulted was a multi-defendant indictment charging

drug conspiracy crimes.   While four co-conspirators entered guilty

pleas, our appellants -- co-defendants Katerin Martínez-Alberto

("Martínez") and Alexandria Andino-Rodríguez ("Andino") -- each

exercised their trial rights.     Following a joint eight-day jury

trial, both were convicted for their roles in the trafficking

venture.

           Now, in these consolidated appeals, Martínez and Andino,

alleging trial and sentencing errors, ask us to reverse what

happened below.    But for reasons we'll explain, we affirm in toto.

                                - 3 -
                                 BACKGROUND

                                   Facts

           Drawing from the record to tell this tale -- and doing

so in the light most favorable to the jury's verdict, see, e.g.,

United States v. Ciresi, 697 F.3d 19, 23 (1st Cir. 2012) (citing

United    States   v.   Mitchell, 596     F.3d   18,     20    n.1   (1st    Cir.

2010)) -- we begin by laying out the facts of the drug-trafficking

scheme in which our appellants were embroiled, providing a good

bit of saga up front in order to facilitate the gentle reader's

understanding of how this all transpired.              We will fill in more

detail later, when additional factual and procedural particulars

become necessary to our analysis.

           Back on January 27, 2018, in the Crown Bay Marina in St.

Thomas,    a   Customs     and   Border    Protection          ("CBP")      marine

interdiction agent had eyes on the Black Wolfpack, a vessel

suspected of trafficking drugs to and from Puerto Rico.1                 Walking

towards the Black Wolfpack, carrying luggage, boxes, and a cooler,

were two men and two women, later identified as Maximiliano

Figueroa-Benjamín       ("Maximiliano"),      Emiliano        Figueroa-Benjamín

     1 Information had been relayed to CBP by the FBI after it
learned from a source of information that a vessel would soon
depart Puerto Rico for St. Thomas, pick up cocaine there, then
return with the kilos to Puerto Rico. As a result, the CBP agent
was called into action "to be on the lookout" that day.

                                   - 4 -
("Emiliano"),2   Martínez,   and    Andino.      All   aboard,   the   Black

Wolfpack departed the St. Thomas marina towards Puerto Rico, but,

about halfway through what became a hazardous return journey,3 it

was intercepted and escorted back to St. Thomas by law enforcement.

           Over the course of their searches that day, federal

agents seized from the Black Wolfpack several items, including the

four individuals' identifications as well as their cell phones.4

Also found and retrieved inside a hidden compartment were 55

bundles of what was believed (and subsequently confirmed) to be

cocaine.    Two days later, agents further searched the Black

Wolfpack, this time finding 56 bundles of suspected cocaine under

a table bolted to the vessel's floor.5        Among the 111 total bundles

seized, there were various stickers and insignia affixed to the

     2Given these first two co-defendants have the same last name,
we use their first names to avoid confusion, no disrespect
intended.
     3  The weather that day wasn't exactly ideal for a leisure
trip between the islands: Agents testified the waves were between
10 and 15 feet high (some of the worst one agent had seen), forcing
the experienced seafaring agents to debate the safety of pursuing
the Black Wolfpack before ultimately deciding to give chase.
     4 Andino and Maximiliano consented to the searches of their
phones. Martínez did not, but after the seizure of her phone from
the arrested Black Wolfpack, federal agents extracted the
information used by the government in its prosecution case. The
record suggests warrants were obtained for the search of and
extraction from each of the phones, but it is not crystal clear.
Regardless, no one has challenged the propriety of the searches on
appeal.
     5   Of the various federal agencies involved, the FBI was
designated the seizing agency.

                                   - 5 -
bricks, including stickers with crowns and $100 bills on them.

All told, the total weight of the 111 cocaine bricks was 132

kilograms, with a street value of $20k-22k per brick (for a grand

total of more than $2 million in value).

          To better understand the scope of what led to this moment

at sea, let us travel back to 2017 to walk through what happened

over the course of the charged conspiracy.   Because while January

27, 2018 was the first time this group got caught, it was not their

first rodeo.

          We introduce you to two names, new to our recounting but

central to the enterprise:    Bernardo Coplin-Benjamín ("Coplin")

and José Javier Resto-Miranda ("Resto").6     It was Coplin who,

around March of 2017, came up with the grand idea to buy a boat

that would move drugs from St. Thomas to Puerto Rico, and in

anticipation of that goal Coplin asked his friend and associate,

     6 With respect to Coplin, we note that he also was indicted,
then pled guilty and was sentenced. In the wake of all that, he
filed a timely appeal. See United States v. Coplin-Benjamin, No.
21-1737. To be clear: We discuss Coplin here based only on the
evidence offered at the joint trial of Martínez and Andino, and we
do so solely for the purpose of fleshing out the trafficking scheme
as it relates to their involvement and issues raised by them in
this appeal. We offer no take whatsoever on the facts or merits
of Coplin's appeal.
          As for Resto, the only co-conspirator to testify at
Martínez and Andino's trial, he has an important role to play in
our factual recitation, and he also figures prominently in one of
the appellate issues we'll be chasing down in the pages to come.

                              - 6 -
Resto, for his help.    In time, Coplin followed up and purchased a

boat:   the Wasikoki.

           In preparation to set sail on their trafficking venture,

Coplin and Resto did some reconnaissance.     To get a read on the

planned route, length of the trip, and fuel costs, Coplin asked

another individual (whose identity is irrelevant here) to captain

a test run.    Aboard that April 2017 Wasikoki trial outing were

Coplin, Andino (a close friend of Resto, who brought her into the

enterprise), and Maximiliano.

           Thereafter, with the route settled, a basic plan was

hatched:   Resto, Maximiliano, Martínez (another of Resto's friends

and recruits), and Andino would make a trip on the Wasikoki to St.

Thomas, with the women playing the roles of "fillers" to erect a

facade of two couples out on a leisure ride (Resto told them they'd

be paid $3,000 apiece for their participation); the group would

pick up the cocaine; and they'd return to Puerto Rico with it.

Come May 2017, they headed out to sea.    Upon their arrival in St.

Thomas, Maximiliano picked up the cocaine from his contact there,

and he and Resto stashed the vacuum-sealed and greased bundles in

a hidden compartment on the Wasikoki.    But then they hit a snag:

The Wasikoki had technical problems.     Resto (as captain on this

voyage) decided the journey would have to be abandoned -- as he

told his companions aboard the vessel, it wasn't worth the risk of

undertaking the drug run on the Wasikoki when she was struggling

                                - 7 -
with mechanical issues and might break down.   Resto gave the kilos

to Maximiliano, who returned them to his contact.      Emptyhanded,

the Wasikoki and its crew then made the return voyage back to

Puerto Rico.

          The Wasikoki's mechanical issues were persistent, as it

turned out, so in May 2017, Resto helped Coplin acquire a new boat:

the Black Wolfpack, which Resto registered in his name.

          In late July or early August of 2017, Resto, Maximiliano,

and Andino (no Martínez this time) climbed aboard the Black

Wolfpack and made another trip to Crown Bay Marina in St. Thomas

to pick up cocaine.   Once there, Maximiliano went to meet with the

supplier while Resto and Andino went to an apartment on St. Thomas

to help get the cocaine ready for its journey to Puerto Rico,

including by putting the coke into packages, some of which had

crowns on the seal.    More on this later.     For context, all the

reader need file away for now is that Andino made another trip,

then helped package the kilos for transport home to Puerto Rico,

where, at Coplin's house, she received $7,000 for her efforts.

Also worth noting now, for purposes of explaining Resto's role in

all of this, is that Resto got $35,000 and complained he "thought

it should be more."

          The Black Wolfpack set sail for St. Thomas yet again in

September 2017, this time with Andino, Maximiliano, Resto, and his

girlfriend (who is not a co-defendant here) aboard, and under the

                               - 8 -
pretext that they were bringing aid in the wake of Hurricane Irma.

Andino   again   participated   in      preparing   the   cocaine   for

transportation, then got back aboard the Black Wolfpack to head

back to Puerto Rico, where she, as before, was paid $7,000 for her

efforts. Resto, again disappointed by his "unfair" payout ($20,000

this time), confronted Coplin, urging that he should be paid more

as captain.   Coplin's response was to tell Resto "to deal with it"

-- "this [was] the way that it was going to be done."       Displeased

and feeling like the risk/benefit balance was not "a good deal"

for him, Resto then "distanced" himself from the group.

          A couple of months later, text messages between Martínez

and Andino reflected an upcoming November 4, 2017 trip.        Indeed,

Crown Bay Marina paperwork bears Andino's registration of the Black

Wolfpack on that same date.      Further proof of that particular

voyage -- telling photos.   There's a November 4 selfie of Martínez

and Andino that was found on Maximiliano's phone during the search

following that January 27, 2018 seizure -- it shows the women

aboard the Black Wolfpack with the cooler they used to transport

the cocaine from its packaging site back to the vessel.             And

Maximiliano is in another picture from his phone -- he's steering

the Black Wolfpack, and Martínez and Andino are standing in close

proximity.    Meanwhile, Martínez's phone contained a November 4

photo showing crown-sticker and $100-bill-sticker bundles.

                                - 9 -
          And St. Thomas got another November 2017 visit from the

Black Wolfpack, this time on the 17th.   Marina registration papers

for that day once more show Andino's signature, and Maximiliano's

phone has a November 19 photo showing him, Andino, Martínez, and

another individual at the cocaine-packaging site (an apartment)

with that telltale cooler used to move the kilos (as Resto attested

at trial) behind them.

          Fast forward to January 2018, back to the events we

started with.   Now, Resto had not been participating in this drug-

trafficking enterprise for a few months, but he was asked to join

for that January 2018 trip.   He declined, instead going to Alaska,

where he would renew his asbestos removal license (he'd worked in

Alaska over the years, he explained at trial). Resto later learned

of his four associates getting busted when Coplin called him and

broke the news that Martínez, Andino, Maximiliano, and Emiliano

had been arrested in St. Thomas.7

                         Procedural History

          In the wake of the January 2018 seizures and arrests, a

second superseding indictment ultimately issued charging Martínez,

Andino, Maximiliano, and Emiliano, and later Coplin and Resto,

     7 A few weeks after that, Resto returned to Puerto Rico and
met up with Andino, who was out on pretrial release, during which
meeting she told Resto the January 2018 crew had actually noticed
they were being followed as they left St. Thomas, and Andino had
suggested they throw away their phones, but Maximiliano rejected
that suggestion because his phone was new and had been pricey.

                               - 10 -
with       conspiracy   to   possess   with     the   intent   to   distribute   a

controlled substance in violation of 21 U.S.C. § 846 (Count One)

and conspiracy to import controlled substances into the U.S. in

violation of 21 U.S.C. § 963 (Count Two) (said conduct beginning

on a date unknown, but not later than 2017, and continuing until

a date unknown, but not earlier than January 27, 2018).

               Over time, each of Martínez and Andino's co-defendants

entered guilty pleas.8         For their part, Martínez and Andino, as we

noted earlier, proceeded jointly to trial, at which both defendants

were found guilty9 and later sentenced (concurrent 120-month terms

of imprisonment, to be followed by concurrent five-year terms of

supervised release, for each defendant).                Appellants timely and

separately appealed, and here we are.

       The important plea to note right off the bat is Resto's.
       8

As relevant to this appeal, Resto's plea included: him copping to
conspiring with his co-defendants to distribute between 15 and 50
kilos of cocaine; his understanding that his sentencing range would
be no less than ten years' imprisonment and at least five years'
supervised release; and his agreement that the parties would
recommend that minimum term to the sentencing court. And Resto
signed a cooperation agreement, too, in which he signaled, among
other things, his willingness to provide truthful testimony at a
future trial.
       The government met its case burden using: the agents that
       9

intercepted and searched the Black Wolfpack; the agents who
extracted the data from the defendants' cell phones; the forensic
chemist who tested the seized cocaine; and a cooperating Resto,
who testified pursuant to a cooperation agreement. It also adduced
photos and video evidence of the searches, the cocaine, and
business records from the marina in St. Thomas, along with the
relevant photos, text exchanges, and voice messages retrieved from
the defendants' phones.

                                       - 11 -
                                DISCUSSION

             The appellate contentions pressed by Martínez and Andino

are discrete ones with no overlap as between each appellant.

Martínez presses three challenges on appeal, each arising from a

different moment during trial.10      In sum, she argues the district

court committed errors (1) regarding Resto's trial testimony, (2)

in making an evidentiary ruling, and (3) when it delivered jury

instructions.      As for Andino, she says the district court erred

when it denied her the minor participant adjustment she sought.

Proceeding chronologically, let's test the waters.

                                 Martínez

          Resto:   Recross-Examination and the Motion to Strike

             Martínez's first argument zeroes in on Resto, the co-

conspirator turned cooperating witness, and a couple of aspects of

the district court's handling of his testimony.     The thrust of her

argument, as we understand it to be, is that two of the district

     10 Below, Martínez made a Rule 29 motion challenging the
government's evidence as to her knowing participation in the
conspiracy.   The district court denied it.      While Martínez's
appellate papers at times suggest that the evidence as to her
conspiracy participation and knowledge wasn't sufficient, we do
not understand her to be advancing a sufficiency-of-the-evidence
challenge here. Nor did the government. To the extent she may
have intended to mount such a challenge before us, we deem it
waived. See, e.g., Rodríguez v. Mun. of San Juan, 659 F.3d 168,
175-76 (1st Cir. 2011) (deeming waived arguments offered with no
citations or analysis); United States v. Zannino, 895 F.2d 1, 17
(1st Cir. 1990) (urging that litigants are required to develop
their own arguments rather than "leaving the court to do counsel's
work").

                                  - 12 -
court's rulings -- its denial of recross of Resto and, later, its

grant   of   the   government's    motion    to   strike   some   of   Resto's

testimony     --   denied   her   the   opportunity   to   impeach     Resto's

testimony and credibility in violation of her Sixth Amendment

Confrontation Clause rights.            To navigate her claims, we first

provide some preliminary guiding principles, then wade into the

transcripts of the waning days of the trial to explicate the

sequence of events and rulings.

             It's axiomatic that "[t]he Confrontation Clause of the

Sixth Amendment guarantees criminal defendants the right to cross-

examine witnesses who testify against them."               United States v.

Maldonado-Peña, 4 F.4th 1, 31 (1st Cir. 2021) (quoting United

States v. Casey, 825 F.3d 1, 23-24 (1st Cir. 2016)), cert. denied

Rivera-Alejandro v. United States, 142 S. Ct. 729 (2021), and cert.

denied Rivera-George v. United States, 142 S. Ct. 1184 (2022), and

cert. denied Rivera-Alejandro v. United States, 142 S. Ct. 1185

(2022).      It allows defendants to "test the believability of a

witness and the truth of his testimony."              Id. (quoting United

States v. Rivera-Donate, 682 F.3d 120, 126 (1st Cir. 2012)). "This

right is not without limits, however; the district court wields

considerable discretion to impose 'reasonable limits' on cross-

examination." Id. (quoting Casey, 825 F.3d at 24); see also United

States v. Kenrick, 221 F.3d 19, 33 (1st Cir. 2000) (en banc)

(acknowledging the district court's extensive discretion when it

                                    - 13 -
comes to controlling recross-examination),           abrogated         on other

grounds   by   Loughrin   v.    United   States,   573   U.S.    351    (2014).

Importantly, "[w]hen a witness's credibility is at issue, the trial

court may limit cross-examination as long as the court allows

sufficient leeway to establish a reasonably complete picture of

the witness' veracity, bias, and motivation."            Maldonado-Peña, 4

F.4th at 31 (quoting Rivera-Donate, 682 F.3d at 126).                   For our

part, we employ a two-step analysis:           We first "review de novo

whether a defendant was afforded a reasonable opportunity to

impeach   a    witness,   and    [second,]   for    abuse   of    discretion

limitations the trial court imposed on that opportunity."                   Id.

(quoting Casey, 825 F.3d at 24); see also United States v. Pérez-

Ruiz, 353 F.3d 1, 11 (1st Cir. 2003) ("In the first instance,

Confrontation Clause challenges are reviewed de novo in order to

verify that the trial court afforded the defendant a reasonable

opportunity     to   impeach      adverse    witnesses.          When      that

constitutional threshold is crossed, we examine the trial court's

restrictions on the manner and extent of cross-examination for

abuse of discretion.").

           Initial guidance in place, we turn back to our case to

see how things played out below.

           On trial days six and seven (of eight), defense counsel

-- first for Andino, then for Martínez -- conducted their cross-

examinations of Resto.          As relevant here, both counsel probed

                                   - 14 -
Resto's cooperation agreement.      Martínez's counsel went further

and explored Resto's purchase and possession of a gun in Alaska,

which he admitted to, as well as his drug-dealing business in

Alaska.    He also acknowledged that his plea agreement did not

include a charge of possession of a weapon in furtherance of drug

trafficking, nor did his sentencing guidelines recommendation

include any points provided for possession of a firearm.11          About

the propriety of his gun ownership, Resto testified his having it

was legal in Alaska, but Martínez's counsel countered by asking,

"[I]sn't it true that even if you buy a weapon . . . you have to

register the weapon with the police department closest to your

home[?]"

           Following cross-examination by both defense counsel, the

government briefly redirected, and during the redirect, Resto

testified there was no connection between his gun ownership and

his selling drugs in Alaska.        Thereafter, the district court

excused Resto from the stand.

           Needing to take care of several procedural housekeeping

matters, the court, outside the presence of the jury, held a

sidebar at which Andino's attorney represented that he had intended

to   recross-examine   Resto   regarding   aspects   of   his   testimony

       The terms of Resto's plea agreement provided the agreement
      11

bound only "the United States Attorney's office for the District
of Puerto Rico and the defendant."

                                - 15 -
concerning his cooperation with the government and benefits he

might have derived from that cooperation. He made a particularized

proffer indicating he would have recrossed on "three specific

moments in which [Resto] was promised by the agents that he was

going to get specific considerations":         (1) the FBI's statements

to Resto which showed they made promises to him including bail and

staying in Alaska; (2) the timing of when Resto began to cooperate;

and (3) Resto's misstatements about what he said during his FBI

interview.    Martínez's counsel, without elaboration, "join[ed]

brother counsel's objection."           The district court denied the

request, indicating that all those proposed topics had already

been    covered   (or   should   have   been   covered)   during   cross-

examination.12

            On the next and final day of the trial, the government,

returning to the topic of Resto's cross-examination, moved to

strike the testimony about Resto's Alaskan gun possession, argued

that whether Resto had registered the gun was irrelevant to his

credibility, and even if he may have run afoul of a registration

requirement, he hadn't been convicted of any such violation. After

       No strictly new topics came up during redirect that would
       12

have, as we sometimes say, opened the door to new lines of inquiry
Martínez's trial counsel couldn't have had an opportunity (or
reason) to ask about up until that door was opened. See generally,
e.g., United States v. Tetioukhine, 725 F.3d 1, 10 (1st Cir. 2013)
(discussing what can suffice "to open the door to further cross-
examination"). Martínez has not argued otherwise.

                                  - 16 -
hearing from each side, the district court granted the motion on

the grounds that Martínez's attorney, when asked, was unable to

cite any firearm ownership law Resto had purportedly violated.

The district court, finding that the gun-in-Alaska questioning

could mislead the jury, instructed the jury to disregard all of

it.

           On appeal, Martínez's argument takes aim at these two

events -- the denial of recross-examination and the grant of the

motion to strike -- and argues the district court's striking of

Resto's gun testimony concerning his possession of the gun while

dealing cocaine, "exacerbated by the court's denial of [her]

opportunity to recross him," had the effect of depriving her "of

the constitutionally required threshold level of inquiry," robbing

her of "sufficient leeway to establish a reasonably complete

picture of the witness's veracity, bias, and motivation."    More

specifically, she argues, the gun evidence could have been used to

show Resto's bias given that the government could have charged

him, but, favorable to him, didn't (see supra note 8),13 or could

have enhanced his sentence, but, again favorable to him, didn't,

      13Martínez does not pursue her trial-stage theory based on
Resto having committed a crime by failing to register his gun in
Alaska.

                             - 17 -
based on firearm possession (see 18 U.S.C. § 924(c)),14 thereby

casting doubt on Resto's credibility.        As she puts it, "[Resto's]

credibility was at the core of the government's case against

Martínez," and the court's double-barreled rulings impinged upon

her ability to attack that credibility.15      Our bottom line takeaway

from her argument boils down to this:       Martínez asserts that being

denied recross and then being unable to argue anything about the

gun at all, because the little gun evidence there was had gotten

stricken,   impacted   her   ability   to   effectively   attack   Resto's

credibility   "by   exploring   the    benefits   he   derived   from   his

cooperation."

            The government offers a fulsome retort to Martínez's

arguments which we'll weave into our analysis as we go along.

            We open by acknowledging our agreement with Martínez's

top line assertion:      The opportunity to recross a witness can

     14 We note Resto was not charged as a felon in possession of
a firearm, presumably because his presentence report reflects that
he had no known criminal history.
     15 We pause to make an observation. To the extent Martínez
intends her arguments contesting the combination of rulings to be
something akin to a violation of the cumulative error doctrine,
see, e.g., United States v. Baptiste, 8 F.4th 30, 39 (1st Cir.
2021) ("The cumulative-error doctrine holds that errors not
individually reversible can become so cumulatively."), at the end
of our analysis of these claims, we find no error and as we've
said before, "[b]ecause we find no merit to the individual claims,
as a matter of course there can be no cumulative error," United
States v. Bulger, 816 F.3d 137, 160 n.25 (1st Cir. 2016) (citing
United States v. Brown, 669 F.3d 10, 28 (1st Cir. 2012)).

                                 - 18 -
implicate the Confrontation Clause.     See, e.g., Pérez-Ruiz, 353

F.3d at 10-11.   And that's where we'll start our review, doing so

with fresh eyes.     Id. at 11 (arraying our court's review as

starting with the de novo consideration of the confrontation-

driven challenge, then, once "that constitutional threshold is

crossed," moving to    abuse-of-discretion   scrutinization of   the

trial court's restrictions on cross).

                 Reasonable Opportunity to Impeach

          Taking a look at the record, it clearly reflects, as the

government contends, that the district court gave Martínez a

reasonable opportunity to confront and impeach Resto.

          As mentioned, cross-examination commenced on trial day

six, a day after the government completed its direct (with the

government briefly "reopen[ing]" direct to show a few pictures).

And as far as cross-examinations go, it went smoothly, with the

district court allowing nearly all lines of inquiry, many of which

prompted responses from Resto that reasonably could tend to cast

doubt on his credibility.    For example, Resto agreed that he had

repeatedly lied to federal agents -- even up to four days before

the trial started -- and that he was never charged with a separate

crime based on these lies.   The jury learned through his testimony

that it was only after his attorney advised him to stop lying that

Resto fully began to cooperate.   The cross also focused on Resto's

signed cooperation agreement with the government and the benefits

                               - 19 -
that he derived from it, including the possibility of a reduced

sentence.     Indeed, even in the wake of some sustained objections

over the course of the two-day cross-examination, the record is

clear "that the defense got its main point[s] across."            Maldonado-

Peña, 4 F.4th at 34-35; Pérez-Ruiz, 353 F.3d at 11 (finding it

"crystal     clear"   that    an   appellant   had   "ample   opportunity    to

confront [the witness's] testimony" when the district court gave

defense counsel a recess after the direct had concluded and "did

nothing to limit the length of [the ensuing] (and skillfully

conducted) cross-examination"); see also Cruz-Rivera, 14 F.4th at

52 (spying no confrontation issue when defense counsel had explored

the witness's bias through a cooperation agreement and reduced

sentence -- and leaned on the same during closing argument).

                          Recross-Examination Request

             What remains, then, at step two, is for us to resolve

whether the denial of recross-examination of Resto constituted an

abuse of discretion.         See Maldonado-Peña, 4 F.4th at 31; Casey,

825   F.3d    at   24.      "The   abuse-of-discretion    standard   is     not

'appellant-friendly.'"         United States v. Marino, 833 F.3d 1, 7

(1st Cir. 2016).         We have said that "[t]he touchstone of abuse of

discretion review . . . is reasonableness."              Id. at 10 (quoting

United States v. Vargas–Dávila, 649 F.3d 129, 130 (1st Cir. 2011)).

This means that we will affirm only if "no reasonable person could

                                     - 20 -
agree with the ruling."    United States v. Rivera-Carrasquillo, 933

F.3d 33, 44 (1st Cir. 2019).

          The short of it is that contrary to Martínez's claim,

and as the government contends, the district court's ruling was

not an abuse of its extensive discretion.           Recall first that it

was Andino's attorney, not Martínez's, who put any meat on the

bones of the objection he made to the court's recross ruling.           And

here, Martínez does not even mention that three-point proffer

Andino's attorney made to the court.            Instead, Martínez's brief

shifts back to talking about the exclusion of the gun testimony

and how the earlier denial of recross prevented defense counsel

from probing Resto's disclaimer of any connection between the gun

and his drug dealing in Alaska.16

          But not only is this rear-view-mirror approach untenable

in light of basic preservation principles, crucially, that's not

how our review of her claim works.               Our examination of her

allegations   of   error   focuses   on   the    district   court   judge's

reasonableness assessment of the evidentiary ruling at the time

the decision was made.     See United States v. Brown, 669 F.3d 10,

     16 We understand her argument on why she believes the court
erred to go like this -- now knowing the district court would later
strike Resto's gun testimony, she would have us consider that
future ruling alongside the recross ruling to strengthen her
contention that the court abused its discretion when it denied her
the opportunity to recross. Creative -- give her that. Yet she
cites nothing to support such a proposition.

                                - 21 -
22 (1st Cir. 2012) (instructing that "[i]mplicit in [the abuse of

discretion] standard is the requirement that we not indulge in

review by hindsight but consider what evidence was before the trial

judge at the time").

           Accordingly, on these facts, we cannot characterize the

district court's denial of recross as an abuse of discretion. See,

e.g., Maldonado-Peña, 4 F.4th at 31; Kenrick, 221 F.3d at 33.

                               Strike Motion

           We turn now to the motion to strike, which generally

gets abuse-of-discretion review.17           See, e.g., United States v.

Sabetta,   373   F.3d   75,   82   (1st   Cir.   2004);   United   States   v.

Houlihan, 92 F.3d 1271, 1297 (1st Cir. 1996).

           Think back to the basic progression that led to the

motion to strike:       defense counsel suggested during cross that

Resto had broken an Alaska law by possessing a gun and failing to

register it; the motion to strike was filed a day later; when

asked, Martínez's counsel could not provide the court with the

Alaska law Resto supposedly broke. In the exchanges that followed,

the court, Martínez's attorney, and the government debated whether

the gun testimony should be stricken, with Martínez's counsel

     17Strictly speaking, Martínez never argues that the grant of
the motion was an abuse of discretion, instead specifically stating
that the ruling as it related to the misleading gun-registration-
law testimony was not something she was actually challenging on
appeal. But this, we note, was the basis for the motion to strike
and its eventual granting.

                                    - 22 -
urging that Resto's apparent belief that he should have registered

the gun goes to credibility.         The exchange also touched on the

point that, according to the defense, Resto derived a benefit from

his   cooperation   because   he   wasn't   charged   under   § 924(c)   as

possessing a firearm in furtherance of drug trafficking.18               For

example, in response to Martínez's counsel's assertion that "the

drugs were drugs that were sent from Puerto Rico" to Alaska, the

court replied, "His testimony was that he had that gun because of

his business of sending drugs to Alaska and selling them, but it

has nothing to do with transporting drugs from St. Thomas to Puerto

Rico."     Counsel said, "That's a classic 924(c), possession of a

firearm in furtherance of a drug trafficking crime," and the court

responded that it had "nothing to do with this case," that "he has

to have actively employed the firearm in furtherance of this drug

crime."

            The government, for its part, maintained that there was

"zero connection" between Resto's gun possession and the facts of

the instant case on trial, and the government "looked into the

possibility of a 924(c) and determined [it] was an unprovable

charge" because "there was no direct linkage to drug trafficking,"

       For inquiring minds, the relevant portion of § 924(c) here
      18

lays out the penalties for "any person who, during and in relation
to any . . . drug trafficking crime . . . for which the person may
be prosecuted in a court of the United States, uses or carries a
firearm, or who, in furtherance of any such crime, possesses a
firearm." 18 U.S.C. § 924(c)(1)(A).

                                   - 23 -
so Resto wasn't "obtaining a benefit by [the government] not

charging him with 924(c)."

            Trying to pin it all down, the court squarely asked

Martínez's counsel, "Whether or not the [g]overnment brought a

924(c), how does that go to [Resto's] credibility?"    In response,

Martínez's counsel revisited Resto's testimony regarding Alaska's

law about purchasing and registering guns, having previously asked

Resto, "And isn't it true that . . . you have to register the

weapon . . .?" and Resto answered, "That is correct." The district

court said, "[B]ut that's beside the point."    Martínez's counsel

replied, "But that goes to his credibility.   He says that he knows

the law."   Said the district court in response:   "But that is not

the law. . . .    I don't care if the witness says that it is.   The

witness can say that opening that door is against the law, and it

isn't.   I am going to strike the testimony."      And strike it he

did, saying the cross-examination concerning the gun had been

improperly misleading.

            Martínez's point here, as she frames it, continues her

central thesis that striking the gun testimony had the effect of

denying her the opportunity to impeach Resto, in a constitutional

sense, and to challenge his credibility.

            We take her argument to be either that Resto's shipping

cocaine to himself from Puerto Rico to Alaska was part of the

Puerto Rico conspiracy or that it was a separate but supportably

                               - 24 -
chargeable § 924(c) crime to possess the gun in furtherance of the

Alaskan drug trafficking (perhaps it's both).     Thus, she again

urges that Resto's gun possession while dealing drugs and lack of

consequences for it, coupled with his cooperation, could have been

used to establish bias for impeachment purposes.      Further, she

says, granting the motion to strike "cannot be deemed harmless"

because Resto was basically the star witness and the case hinged

on his credibility.   Regardless of which § 924(c) angle is the

primary play here, and assuming her argument is preserved,19 we

conclude, contrary to Martínez's assertion, that any error was

harmless.20

     19 Martínez's counsel's answer to the district court's
§ 924(c) question did not directly posit any analysis of how such
a charge not being brought impacts Resto's credibility, but,
because it makes no difference to our outcome and we think enough
lies latent in the record exchanges to give texture to the
argument, we will bypass waiver.
     20 Our harmlessness inquiry can go one of two ways, with us
inquiring whether: (1) any error was harmless beyond a reasonable
doubt, see United States v. George, 761 F.3d 42, 56 (1st Cir. 2014)
(sidestepping   whether   an   evidentiary   ruling   offended   an
appellant's confrontation rights "because even if an error
occurred (something we do not decide), that error was harmless
beyond a reasonable doubt" (citing United States v. Earle, 488
F.3d 537, 542 (1st Cir. 2007) (instructing that "[i]f a
constitutional error has occurred, we must order a new trial unless
the government has shown that any error was 'harmless' beyond a
reasonable doubt"))); or (2) any error was harmless in that it did
not affect Martínez's substantial rights, see Fed. R. Civ. P. 61
("At every stage of the proceeding, the court must disregard all
errors and defects that do not affect any party's substantial
rights."); see also Tersigni v. Wyeth, 817 F.3d 364, 369 (1st Cir.
2016) ("We may affirm in spite of an erroneous evidentiary ruling
if the error was harmless, meaning that 'it is highly probable

                              - 25 -
           "Harmlessness turns on things like the importance of the

testimony to the case, the cumulativeness of the testimony, the

presence   or      absence     of     other     evidence      corroborating   or

contradicting   the    testimony,       the    extent   of    permitted   cross-

examination, and the overall strength of the government's case."

George, 761 F.3d at 56 (citing Earle, 488 F.3d at 546).               And "[w]e

will affirm a conviction if the 'contested . . . statements . . .

were at best cumulative of other compelling proof that [the

defendant] committed the charged [crime].'"                  Earle, 488 F.3d at

546 (quoting United States v. Bartelho, 129 F.3d 663, 670 (1st

Cir. 1997)).

           Here,     our     review    of     the   above-described    list   of

harmlessness considerations prompts our conclusion that any error

regarding Martínez's ability to probe Resto's credibility was

indeed harmless.       As the government points out, even without

Resto's gun testimony in the evidentiary mix, Martínez had, as

we've already described, plenty of tools available to her to

impeach Resto's credibility -- her counsel was still able to use

that the error did not affect the outcome of the case.'" (quoting
McDonough v. City of Quincy, 452 F.3d 8, 19-20 (1st Cir. 2006))).
     While we grant (and have examined how) a recross issue does
tap into constitutional confrontation issues, it is not clear (and
Martínez does not say) why the motion to strike necessarily follows
suit. Because the government carries the burden here, see Earle,
488 F.3d at 542, and because we would find harmlessness under
either approach, we follow the government's lead and apply the
"harmless beyond a reasonable doubt" lens.

                                      - 26 -
the   defense's    effective      cross-examinations   during    closing

arguments, hammering home for the jury's benefit Resto's potential

bias, motives, and truthfulness issues on points apart from the

gun testimony.     For example, the jury heard Resto readily cop to

wanting the best possible deals, and cooperation was one way to

get a better sentence.     And another benefit of Resto's cooperation

was the drug quantity stipulation he secured -- 15 to 50 kilos of

cocaine as opposed to the significantly higher quantity he actually

trafficked based on the evidence the jury heard.        His pattern of

lying to agents (but not being charged for doing so) and minimizing

his involvement in the trafficking scheme was likewise probed

during Resto's testimony, then used during closing arguments. Also

during closings, defense counsel was able to highlight Resto's

plea and cooperation agreements for the jury and counseled the

jury to "consider . . . immensely" how much to trust Resto based

on his testimony because his plea deal meant that he was on "un

dedo pillao" (a short leash) with the government.

          Aside     from   this    effective   dissection   of   Resto's

credibility, the record reflects that the jury heard and saw ample

evidence establishing Martínez's knowing involvement in the drug-

smuggling enterprise -- and corroborating Resto's telling of the

tale, to boot.     Consider, for example (this list of evidence is

non-exhaustive):

                                  - 27 -
  •   The day the 28-foot Black Wolfpack (with 111 kilos stashed on

      it) was intercepted at sea, Martínez was aboard;

  •   The evidence extracted from her cell phone included text

      messages from Martínez saying she was "working" and "rich"

      during the January 2018 trip to St. Thomas;

  •   November 3, 2017 text messages between Martínez and Andino

      showed   Martínez   responding   to   Andino's   "[w]e're   leaving

      tomorrow early" message with "[o]kay.      We're ready";

  •   Then, Martínez's cell phone took a November 4, 2017 picture

      of cocaine bricks -- the same day Andino registered the Black

      Wolfpack at the marina in St. Thomas; and

  •   Martínez appears in a November 19, 2017 photograph at the St.

      Thomas apartment where the cocaine had been packaged.

As the government argued to the jury in closing, "[Y]ou don't need

Mr. Resto to tell you the story, the phones an[d] the documents

tell you the story already."

           Taking everything into account, in view of our case law's

harmlessness considerations (like strength of the government's

case, corroborative or contradictory evidence, cumulativeness, the

extent of permitted cross-examination), and even if Martínez's

motion-to-strike arguments have some merit, on this record, any

error in granting the motion was harmless beyond a reasonable

doubt.   See George, 761 F.3d at 56; Earle, 488 F.3d at 542.

                                - 28 -
                                 The Foot

             On the heels of her Resto-based asseverations comes

Martínez's argument that the district court committed error by

denying her request to (literally) put her foot in evidence, i.e.,

showing it to the jury so, as she tells it, the jury could compare

that evidence to the government's photographic evidence.             As the

record and resulting appellate arguments bear out, this request

produced a somewhat distinctive evidentiary situation.              We begin

again with the specifics of what happened below.

             Journey back with us to the close of trial proceedings,

to when, before bringing the jury in for final instructions, the

district     court   asked   defense   counsel   whether   either    of   the

defendants would testify.       Martínez and Andino each said no.         And

the record reflects the defense had no witnesses it wished to call,

either.     But counsel for Martínez stated he did want to present

"one piece of evidence":         an in-court exhibition of Martínez's

foot.      The idea was for the jury to compare her foot to (what

Martínez says is) a foot that appears in the government's Exhibit

88.21 22   The district court hesitated, querying how anyone would

       Exhibit 88 was a photograph extracted from Martínez's phone
      21

depicting cocaine bundles with crown stickers and $100-bill
stickers affixed to them. The photograph was taken on November 4,
2017. On the bottom right side of the photograph, there is a dark
and blurry shape. According to Martínez, that shape is a foot.
       This, we gather from the record exchanges, was the basic
      22

gist of the proffer -- the in-court foot display, as direct
evidence, would prompt a comparison to Exhibit 88 that would rebut

                                  - 29 -
"know it's her foot" in the photo and why this should be probed

outside of closing arguments, then reasoning Martínez's counsel

couldn't argue Exhibit 88 did not depict Martínez's foot unless

she testified about it.

           Martínez's counsel tried to clarify by stressing

     all we are going to show the jury is Ms. Martínez-
     Alberto's foot. I'm going to request that a screen shot
     be taken, and that be Defense Exhibit 2, and that is all
     that we are planning on doing. We're not going to ask
     any questions, we're not making any statements, that is
     all that we're going to do in this case, Your Honor.

The district court's response was to say Martínez would need to

testify as to whether the exhibit depicts her foot.           And when in

response Martínez's counsel asked if he could ask his client one

question   --   "Is   the   foot   that   appears   on   Exhibit   88   your

foot?" -- the district court again reasoned that Martínez couldn't

what Martínez says was the government's argument that it is her
foot in Exhibit 88 and is evidence of her presence and knowledge
while aboard the Black Wolfpack. (Our review finds no basis for
the assertion that the government advanced such an Exhibit 88
argument, as we'll soon get to.)     This proffer could have been
cleaner, but for purposes of our review, we need not grapple with
it.   See Fed. R. Evid. 103(a)(2); see also Kelley v. Airborne
Freight Corp., 140 F.3d 335, 347 (1st Cir. 1998) (cautioning that
a court cannot "assess the importance of [] excluded evidence,"
absent compliance with Fed. R. Evid. 103(a)(2), when the proponent
of the evidence "[a]t no time . . . ma[d]e an offer of proof that
described the basic contours of the evidence [it] planned to
introduce"); Earle v. Benoit, 850 F.2d 836, 847 (1st Cir. 1988)
(declining to review a claim when the proponent of the evidence
never made an offer of proof describing the substance of the
proposed evidence, reasoning that "the offer of proof device
exists" for instances in which "a court refuses to receive evidence
and yet the same is needed to elucidate [a] proponent's claim for
admissibility, that the offer of proof device exists").

                                   - 30 -
just show her foot to the jury; she'd need to testify, and she

could be subject to cross-examination if she did.                 And so, counsel

for Martínez said, "We have no evidence."23

              Before us, Martínez says it was error for the district

court to deny her the opportunity to show her foot to the jurors.

Specifically, she urges it was incorrect to conclude that Martínez

would open herself up to cross-examination if she showed her foot

since   doing      so   isn't   testimonial   --    and    this   error    was   not

harmless, she says, in that "[t]he evidence of Martínez's knowledge

of the conspiracy was not overwhelming," "[t]he photograph showing

the foot next to the bricks of cocaine was the most compelling

evidence of knowledge," and the government "extensively relied

upon    it"   to    argue   she   knew   about     and    was   involved   in    the

conspiracy.

              The government parries by offering a variety of reasons

why the district court was right to reject Martínez's request.

For instance, the government posits that Martínez failed to lay

       23 The district court pointed out the possible risk of Martínez

taking the stand to testify about Exhibit 88 and her foot in that
it might open her up to cross-examination on topics beyond "the
foot."   See, e.g., Johnson v. United States, 318 U.S. 189, 195
(1943) (explaining that "[t]he case of an accused who voluntarily
takes the stand and the case of an accused who refrains from
testifying are of course vastly different" -- a "voluntary offer
of testimony upon any fact is a waiver as to all other relevant
facts, because of the necessary connection between all" (quoting
8 Wigmore, Evidence § 2276(2) (3d ed. 1940))). We note this, but
need not opine on it given our outcome.

                                     - 31 -
any foundation for the evidence (her foot), and that because of

this failure, it would render this evidentiary offer irrelevant.

Moreover, according to the government, Martínez's characterization

of Exhibit 88 and how the government used it at trial is off.

Contrary to her insistence otherwise, says the government, that

photo wasn't used to identify her foot and thus prove her knowledge

of the conspiracy or her presence on the Black Wolfpack (whether

by the purported foot itself or its proximity to the cocaine or,

perhaps, the suggestion that she was the one who took the photo);

rather, Exhibit 88 was used to show that Martínez's phone took a

November 4, 2017 photo that showed logos on cocaine bundles, and

those matched later images of similarly packaged and stickered

cocaine bundles that were seized from the Black Wolfpack in January

2018.

          We will review for abuse of discretion the foot-as-

evidence issue.24   See, e.g., United States v. Vázquez-Soto, 939

F.3d 365, 373 (1st Cir. 2019); United States v. Zaccaria, 240 F.3d

75, 78 (1st Cir. 2001) (stating abuse-of-discretion review applies

to district court rulings admitting or excluding evidence and, in

     24 Our review of the record suggests Martínez did not lodge
an objection to the court's ruling, but it is not clear. So we
stick with abuse-of-discretion review for this argument.      See,
e.g., United States v. Rosado-Pérez, 605 F.3d 48, 54 & n.2 (1st
Cir. 2010) (opting to conduct abuse-of-discretion review even when
the appellants "did not always clearly object" and hadn't
"preserved every concern they raise[d] on appeal").

                              - 32 -
so    doing,    noting     that      "[e]very       trial    presents    a    blend    of

idiosyncratic        circumstances,"       so        "presiding    judges     must     be

afforded some leeway in making evidentiary rulings").                         And from

our    vantage       point,    this     issue's       resolution     turns     on     the

fundamentals of introducing evidence.                       Martínez's counsel ran

afoul of those fundamentals relative to the proposed display of

his client's foot in a way that undercuts her argument on appeal:

the failure to proffer a proper evidentiary foundation.

               "District      courts    'have       wide    discretion   in    deciding

whether an adequate foundation has been laid for the admission of

evidence.'"      United States v. Velazquez-Fontanez, 6 F.4th 205, 221

(1st Cir.) (quoting Veranda Beach Club Ltd. P'ship v. W. Sur. Co.,

936 F.2d 1364, 1371 (1st Cir. 1991)), cert. denied, 142 S. Ct. 500

(2021), and cert. denied sub nom. Resto-Figueroa v. United States,

142 S. Ct. 1164 (2022); see also Gomez v. Rivera Rodríguez, 344

F.3d 103, 117 (1st Cir. 2003) (instructing that "the determination

of    whether    a    party    has     built    a    proper    foundation      is    left

principally to the sound discretion of the presider").25

       This is a good moment to revisit Martínez's depiction of
       25

the district court's ruling as being based on the foot-display as
testimonial and thus triggering cross-examination, very cause-and-
effect style. Certainly, the record reflects some debate about
whether Martínez would testify and whether she'd then be subject
to cross as a result. But the record also can be fairly read to
reflect the district court's more threshold confusion and concern
about the proposed evidence having no foundation, nothing to
actually get it into evidence -- unless, for example, Martínez
testified about it.    Indeed, on balance, the record shows the

                                         - 33 -
             And when, as here, an evidentiary dispute arises, and

when tendering an evidentiary proffer to the court in support of

admissibility, "the most important procedural rule is that the

proponent of an item of evidence must ordinarily lay the foundation

before formally offering the item into evidence."                       Edward J.

Imwinkelreid, Evidentiary Foundations, § 1.02[1] (10th ed. March

2018).       "At a bare minimum, the requisite foundation demands

something     more      than   intuitive     judgments    emanating    from   broad

generalities."          Gomez, 344 F.3d at 117; see also Kissinger v.

Lofgren, 836 F.2d 678, 683 (1st Cir. 1988) (explaining that a

proper foundation for evidence requires its proponent to provide

"'evidence sufficient to support a finding' that the evidence is

what the proponent claims it to be" (quoting 5 J. Weinstein & M.

Berger, Weinstein's Evidence, ¶ 901(a))); Fed. R. Evid. 104(b).

             Important here, building a proper evidentiary foundation

involves demonstrating the relevance of the proffered evidence.

See Fed. R. Evid. 401 (providing that evidence is relevant if

"(a) it has any tendency to make a fact more or less probable than

it   would    be    without     the   evidence;    and    (b) the     fact    is    of

consequence        in   determining    the    action");    Fed.   R.   Evid.       402

situation, wrestling with logistics (Martínez was the only
possible defense witness; there was no one else to call to talk
about her foot) and the customary, gateway questions swirling
around foundation.

                                       - 34 -
(relevant evidence is admissible).                "In general, with respect to

an   item    of   real    evidence,      a    foundation     must      be    presented

establishing that the item is relevant, its identity, and that its

condition has not materially changed." Test for Relevant Evidence,

Courtroom Handbook on Federal Evidence, Ch. 5 Rule 401 (2023).

"With respect to an item used demonstratively or illustratively,

the foundation must establish that the item depicts relevant

information that is or will be proven by other, substantive

evidence; that it is accurate; and that it will probably aid the

trier of fact in understanding the evidence."                    Id.   And relevance

must be "determined in the context of the facts and arguments in

a particular case."         Sprint/United Mgmt. Co. v. Mendelsohn, 552

U.S. 379, 387 (2008); see also Advisory Committee's Notes on Fed.

R. Evid. 401, 28 U.S.C. App., p. 864 ("Relevancy is not an inherent

characteristic of any item of evidence but exists only as a

relation between an item of evidence and a matter properly provable

in the case.       Does the item of evidence tend to prove the matter

sought to be proved?").

             So, what would the relevance of Martínez's in-court foot

display be?       Her suggestion, recall, is that her in-court display

would tend to rebut what she characterizes as the government's

suggestion that it is her foot in Exhibit 88, making her in-court

display     relevant     inasmuch   as       it   could   tend    to   disprove    her

knowledge, presence, and participation in the scheme.                       To do this,

                                      - 35 -
though, she needed to foundationally connect these evidentiary

dots -- and she did not.

            We explain, starting with Exhibit 88 itself.            To admit

this picture (showing cocaine bundles with crown stickers and $100-

bill stickers affixed to them) into evidence, the government called

the special agent who conducted the extraction that led to the

discovery of the photograph on Martínez's phone.             As pertinent

here, when the government showed Exhibit 88 to the agent, he

testified that he recognized it because the "image [was] part of

the extraction that [he] performed of the phone."           After Exhibit

88 was admitted, the government continued:

     [Government]:   So this was an image that you found,
     correct, on this phone?

     [Agent]:    Correct.

     [Government]:     And this phone belonged to [Martínez].

     [Agent]:    Correct.

In response to the government's further questioning, the agent

testified   as   to   Exhibit   88-1,   "the   report   performed    of   the

telephone extraction." As the agent confirmed, the report captures

information about Exhibit 88.           Looking at the extraction and

metadata report, the agent explained (in some technical detail not

necessary to get into here) that the photo (Exhibit 88) was taken

on November 4, 2017 at 9:49 p.m. using Martínez's phone.             Over an

                                  - 36 -
objection unrelated to any issue on appeal, Exhibit 88 was admitted

in full.

             The next day, Resto was questioned by the government

about the process he and his crew undertook when packaging their

kilos.     Resto was asked whether the wrapping pictured in Exhibit

88 (which was on display for this line of questioning) was what

was done to the kilos of cocaine he and his partners would

transport, and he confirmed, "That is correct[, t]his is how they

[were] received" and then wrapped by his team.

             Having studied the record and the Exhibit 88-related

exchanges closely, we agree with the government that in her efforts

to convince the court to permit the in-court display of her foot

(and still before us), Martínez mischaracterized the government's

use of and reliance on its Exhibit 88 at trial. The record reflects

that Exhibit 88 was not introduced by the government for the

purpose of identifying Martínez or to intimate that the blurry

shape at the bottom of the photo is Martínez's foot.    Rather, the

significance of Exhibit 88, as the government set forth in the

foundation it laid for admissibility, was in its timing and what

it showed:    A November 4, 2017 photo on Martínez's phone, aligning

with the Black Wolfpack's November 4, 2017 trafficking journey,

showing cocaine bundles with stickers that matched those appearing

on bundles seized after the January 2018 arrests.     The fact that

                                - 37 -
a foot might be in the photo was of no moment to the government's

case.

          Thus, the significance of the display of Martínez's foot

-- whether exhibiting her foot directly to the jury, putting it on

the court's projector, or taking a screenshot so the jury could

get a good look at it -- to permit the jury to contrast it with

"the foot" in Exhibit 88 rested on a faulty relevancy premise to

begin with.   Martínez has not shown how her proposed foot evidence

(a) has any tendency to make a fact of import here more or less

probable than it would be without the evidence, and (b) why the

foot evidence is of consequence in determining some action of

consequence to the government's case or to her defense.26   See Fed.

R. Evid. 401 (providing that evidence is relevant if "(a) it has

any tendency to make a fact more or less probable than it would be

without the evidence; and     (b) the fact is of consequence in

     26Nothing in Martínez's briefing reasonably explains how her
proposed foot evidence implicates her knowledge or any other
rational theory of defense.     For instance, if the jury made a
determination that "the foot" in Exhibit 88 was not her foot, she
doesn't explicate why such a finding would somehow demonstrate her
ignorance of the drug smuggling activity on January 27, 2018. See,
e.g., United States v. Andino-Morales, 73 F.4th 24, 42 (1st Cir.
2023) (citing Zannino, 895 F.2d at 17); Díaz-Alarcón v. Flández-
Marcel, 944 F.3d 303, 313 (1st Cir. 2019) (noting that "developing
a sustained argument out of . . . legal precedents is a litigant's
job, not ours" (internal quotations and citation omitted)).

                               - 38 -
determining the action"); Fed. R. Evid. 402 (relevant evidence is

admissible).27

          Indeed, on the record before us and bearing in mind the

above-recapped guiding principles of relevancy, we do not see --

and Martínez has not shown -- why a direct-evidence-showing of her

foot would be relevant.28   Accordingly, we cannot say it was an

abuse of discretion to exclude the display of Martínez's foot.

                        Jury Instructions

          Martínez's third and final appellate argument is of the

instructional variety, and it has two dimensions:    The district

court committed error when it failed to instruct the jury to

consider the charges against Martínez and Andino separately, and

in the instructions it did issue, it impermissibly and repeatedly

referred to the defendants as a single unit.        We begin our

inspection of this assertion by setting the instructional scene,

then we'll drill down on these arguments.

     27 And,moreover, absent her testimony, Martínez offered no
avenue for adducing that her foot, as it would have appeared that
day at trial in 2019, resembled or was similar to how her foot
would have looked on or around the date that picture was taken in
2017 -- a piece of the foundational puzzle.
     28And at any rate, other evidence supported the government's
position that Martínez was a knowing member of this conspiracy:
Resto's testimony (regarding recruiting and working with her, for
instance); her own text-message statements -- on dates when the
Black Wolfpack was in St. Thomas -- about working and being rich
while "not in PR"; and a picture of some bricks taken by her phone
while in St. Thomas.     And recall, Martínez does not mount a
sufficiency-of-the-evidence challenge on appeal.

                             - 39 -
           In the lead-up to trial, the district court issued an

order directing the parties to submit proposed jury instructions.

The government filed proposed instructions; neither Martínez nor

Andino followed suit.      In time, the district court gave counsel

its proposed jury instructions and verdict forms for their review,

some   changes   were   made   during   the   charging   conference,   the

instructions were redistributed to all counsel at the end of trial

day seven, and then, at the close of evidence, the district court

read the instructions to the jury.

           Throughout the instructions, the district court referred

to Martínez and Andino as "the defendants," and "they," "their,"

and "them," too.   One example of many such instances came when the

district court instructed the jury that, "Even if the Defendants

were not part of the agreement at the very start, they can be found

guilty of conspiracy if the Government proves that they willfully

joined the agreement later."      This phrasing occurs throughout the

instructions.    Later, the district court did instruct that the

jury could not "find the Defendants guilty unless [the jury found]

beyond a reasonable doubt that each of them participated in the

conspiracies as charged with at least one other person, whether a

Defendant or not."       Additionally, each defendant had her own

verdict form.    The district court separately identified each form

("There are two verdict forms; one for each Defendant.") and read

each form to the jury.     Martínez's verdict form directed the jury

                                  - 40 -
to   determine    whether   Martínez     was   guilty   or    not   guilty   for

conspiring to possess with the intent to distribute and import

cocaine, and did not mention Andino; Andino's form communicated

the same directive, likewise never mentioning Martínez.

            Debuting her concerns about the instructional phase,

Martínez focuses on two aspects of what happened during the jury

charge.     First, she says the district court failed to issue an

instruction to the jury directing it to consider each defendant

separately and not think of them as a group.               Second, she argues

the district court's consistent and repeated reference to the

defendants as a unit constituted prejudicial error because there

was more extensive evidence against Andino than Martínez.               Indeed,

Martínez urges that the district court's error was not putting the

terms     "each   of"   before   every    mention     of     "the   defendants"

throughout, instead doing so only once -- that "each of them

participated in the conspiracies" line we mentioned -- and even

that was against the backdrop of many more instructions that group

them together as one entity.           And Martínez further argues the

separate jury verdict forms shouldn't impact our calculus at all

since they are not instructions, but rather are a mere end-of-the-

process formality that could not undo the damage that had already

been done during the instructional phase.

            For   its   part,    the     government     disagrees     entirely,

maintaining that a whole-picture view of the jury charge plainly

                                   - 41 -
demonstrates the jury was told to consider Martínez and Andino

separately to determine guilt as to each individual woman.

             Martínez correctly owns that there was no objection to

the final instructions below, which contain the offending language

she now protests on appeal.       Given this concession, and assuming,

contrary to the government's assertion, the argument is not waived,

see United States v. Clough, 978 F.3d 810, 823 (1st Cir. 2020)

("We need not linger over [appellant's] contentions because he

waived this claim by failing to request such an instruction

below."), our review of these contentions is, at best, for plain

error,29 see United States v. Cruz-Ramos, 987 F.3d 27, 39 (1st Cir.

2021) (explaining that an appellant "must run the usually lethal

gauntlet of plain-error review" on his instructional-error claim

when he did not raise the issue below).       This requires Martínez to

"make the difficult showing that the judge erred and clearly [or

obviously] so, and that the error also affected [her] substantial

rights -- but even then we can still affirm if [she] does not show

as well that the error seriously harmed the fairness, integrity,

or public perception of [her] trial."       Id.; see also United States

v. Bauzo-Santiago, 867 F.3d 13, 22-23 & 23 n.8 (1st Cir. 2017).

"This     standard   is   exceedingly   difficult   to   satisfy   in   jury

Rules of Criminal Procedure, Rule 30(d) "precludes appellate
review" except for plain error.

Cir. 2006) (quoting United States v. Paniagua-Ramos, 251 F.3d 242,

246 (1st Cir. 2001)).

            "When applying the plain error standard in the context

of jury instructions, [this court] look[s] at the instructions as

a whole to ascertain the extent to which they adequately explain

the law without confusing or misleading the jury." Bauzo-Santiago,

867 F.3d at 23 (quoting United States v. Candelario-Santana, 834

F.3d 8, 27 (1st Cir. 2016)) (cleaned up); see also United States

v. Padilla-Galarza, 990 F.3d 60, 83-84 (1st Cir. 2021) (observing

that this review of jury instructions "is context-dependent and

must take into account the jury instructions as a whole"); United

States v. Vega, 813 F.3d 386, 396–97 (1st Cir. 2016) (concluding

on plain-error review that, "read[] against the backdrop of the

charge as a whole," the jury instructions were sufficient, even if

not "letter perfect" (quoting Paniagua-Ramos, 251 F.3d at 246-

47)).   Given all of this, we've said this lens of review "is cold

comfort   to    most   defendants   pursuing   claims   of   instructional

error."   Mitchell, 596 F.3d at 25 (quoting United States v. Gómez,

255 F.3d 31, 37 (1st Cir. 2001)).

            The stage set, we proceed to our plain-error review,

mindful that "a reversal on instruction-error grounds is 'a remedy

                                    - 43 -
that is granted sparingly.'"    United States v. Takesian, 945 F.3d

553, 566 (1st Cir. 2019) (quoting United States v. Gelin, 712 F.3d

612, 620 (1st Cir. 2013)).     We won't hide the ball:   Martínez's

instructional-error arguments cannot withstand the "exceedingly

difficult to satisfy" plain-error scrutiny, González-Vélez, 466

F.3d at 35, and that is because we discern no clear or obvious

error.

           Martínez says the district court should have included an

(unrequested) instruction that the jury consider the defendants

separately, and its failure to do so -- coupled with its repeated

lumping together of "the defendants" during the jury charge -- is

an error that was plain.        But in looking at these arguments

"against the backdrop of the charge as a whole," Vega, 813 F.3d at

396–97 (quoting Paniagua-Ramos, 251 F.3d at 246-47), it's clear

they were sufficient and no clear or obvious error lies.

           True, the district court did not say "each defendant" or

place "each of" before "the defendants" throughout the jury charge.

But these standard instructions, again, read in context and as a

whole, had the effect of appropriately directing the jury to

consider   Martínez   and   Andino   separately.    Early   in   the

instructions, setting the stage and tone, the district court told

the jury that (emphasis ours)

     [t]he presumption of innocence alone may be sufficient
     to raise a reasonable doubt and to require the acquittal
     of a Defendant.    The Defendants before you, Katerin

                                - 44 -
     Martínez-Alberto and Alexandria Andino-Rodríguez, have
     had the benefit of the presumption of innocence
     throughout the trial and you are not to convict them of
     the charges against them unless you are persuaded of
     their guilt of these charges beyond a reasonable doubt.
Later, the district court was clear that the jury could not "find

the Defendants guilty unless [it found] beyond a reasonable doubt

that each of them participated in the conspiracies as charged with

at least one other person . . . ."          (Emphasis added.)       We also

note that the jury had before it the defendants' indictment -- the

charging document that spells out the counts against each defendant

-- which the district court referenced throughout its instructions

and gave to the jury (the government having redacted Maximiliano

and Emiliano from it) for its use during deliberations.              Add to

that (as the government points out) the separate jury verdict forms

canvassed    thoroughly   during   the   jury   charge.     Remember,    the

district court told the jury, "There are two verdict forms; one

for each Defendant," then walked through each form for the jury's

benefit, with Martínez's verdict form being entirely unique to her

and the charges against her, never mentioning Andino, who had her

own jury verdict form.30    And as for Martínez's assertion that any

     30   For example, the district court read into the record:
     [A]s to Ms.     Martínez-Alberto,      the   verdict   reads   as
     follows:
     "As to the charge in Count One of the indictment,
     conspiring to possess with intent to distribute cocaine,
     we, the jury, unanimously find the Defendant, Katerin

                                   - 45 -
consideration of an extraneous document like a jury verdict form

should not be part of our decisional calculus, we believe the

district court's careful review of the purpose and operation of

the forms would have clarified any possible ambiguity in the

jurors' minds about their decision-making responsibilities towards

each defendant.

             And despite Martínez's protestations to the contrary,

our case law does not favor her position given our standard of

review here.       We've described a plain (i.e., clear or obvious)

error as being one that is "'indisputable' in light of controlling

law."      United States v. Rabb, 5 F.4th 95, 101 (1st Cir. 2021)

(quoting United States v. Jones, 748 F.3d 64, 70 (1st Cir. 2014)).

While some of the cases to which Martínez points flag steps that

may   be   taken   during   the   jury   charge   to   dispel   the   risk   of

prejudice, like issuing an instruction that the jury give separate

      Martínez-Alberto," and then there is a place for you to
      check "guilty" or "not guilty".
      And as to the charge in Count Two of the indictment,
      "Conspiring to import cocaine into the customs territory
      of the United States from a place outside the customs

      States, we, the jury unanimously find the Defendant

      to check "guilty" or "not guilty".

      There is a place for the jury foreperson to sign and

The district court then did the same with Andino's verdict form.

consideration to each defendant, we are unaware of any controlling

law that affirmatively obligates courts to issue this specific

instruction in order to avoid committing clear and obvious error.

And when, as here, a full-picture review of the instructional phase

shows the jury was sufficiently clear on its task to consider the

defendants and the evidence against each separately, there is no

indispensable need for such a requirement.31

          In   all,   in   view   of   our   context-dependent    reviewing

parameters, Martínez has not shown plain error.                  See, e.g.,

Padilla-Galarza, 990 F.3d at 83-84; Bauzo-Santiago, 867 F.3d at

23; Vega, 813 F.3d at 396–97.

     31 Were Martínez's jury instruction challenge preserved
(thereby triggering a more appellant-friendly standard of review),
this might have been a closer call. As we've said, when it comes
to jury instructions in multi-defendant trials, the best practice
is for district courts to take care to instruct in the clearest
possible terms as to each individual defendant -- one way to do so
is to proactively issue instructions to avoid the spillover
prejudice Martínez is concerned about here.     See, e.g., United
States v. Simon, 12 F.4th 1, 44 (1st Cir. 2021) (relying on the
district court's "prudent[]" instruction to the jury "to treat
each defendant individually and to weigh separately the evidence
as to each defendant" to combat the risk of prejudice), cert.
denied sub nom. Kapoor v. United States, 142 S. Ct. 2811 (2022),
and cert. denied sub nom. Lee v. United States, 142 S. Ct. 2812
(2022); González-Vélez, 466 F.3d at 35-36 (relying in part on the
district court having "explicitly stat[ed] that, '[T]he evidence
pertaining to each defendant should be considered separately and
individually'" to conclude "the instructions did not constitute
error as to the finding of guilt").

                                 Andino

           We come now to Andino and the sole issue she raises on

appeal, a sentencing challenge.         Andino says the district court

committed reversible error when it denied her request for a

mitigating role adjustment pursuant to the federal sentencing

guidelines, and that error resulted in the improper calculation of

her guidelines sentencing range.         Having carefully reviewed the

sentencing record, we are unconvinced.        Before we explain why that

is so, we offer a little contextual primer on the sentencing

framework in which Andino's appellate contention operates and the

lens through which we must review it.

           Andino's    sentencing      challenge    is    based     upon   the

guidelines' available downward adjustments for a defendant who

played a mitigating role in an offense.            Specifically, section

3B1.2 of the guidelines allows a court to decrease a defendant's

offense   level   by   four   levels    if   she   is    deemed    a   minimal

participant, two levels if she is deemed a minor participant, and

three levels if the case falls somewhere in between.              See U.S.S.G.

§ 3B1.2; see also United States v. De la Cruz-Gutiérrez, 881 F.3d

221, 225 (1st Cir. 2018) (tracking some of the evolution of this

reduction).   "Adjustments under this section apply to defendants

whose role in the offense make them 'substantially less culpable

than the average participant in the criminal activity.'"                United

States v. Mendoza-Maisonet, 962 F.3d 1, 23 (1st Cir. 2020) (quoting

                                 - 48 -
U.S.S.G. § 3B1.2 cmt. n.3(A)). A defendant "who [is] plainly among

the least culpable of those involved in the conduct of a group" is

considered a minimal participant.               U.S.S.G. § 3B1.2 cmt. n.4.

Alternatively, a minor participant is one "who is less culpable

than most other participants in the criminal activity, but whose

role could not be described as minimal."            Id. cmt. n.5.

            Now, our method of review for Andino's mitigating-role

argument.        Zooming out for the basics, we review procedural

reasonableness challenges like Andino's              "under a multifaceted

abuse-of-discretion standard whereby we afford de novo review to

the    sentencing   court's    interpretation      and     application   of   the

sentencing guidelines, assay the court's factfinding for clear

error, and evaluate its judgment calls for abuse of discretion."

Mendoza-Maisonet,      962    F.3d   at   20    (quoting    United   States   v.

Arsenault, 833 F.3d 24, 28 (1st Cir. 2016)).

            Narrowing our focus to the sort of mitigating role

adjustment issue we're confronted with in this case, we emphasize

that    "[t]he    defendant   seeking     the   mitigating    role   adjustment

'bears the burden of proving, by a preponderance of the evidence,

that [she] is entitled to the downward adjustment.'"                 Id. at 23

(quoting United States v. Arias-Mercedes, 901 F.3d 1, 5 (1st Cir.

2018)).     We've often warned that, "[b]ecause determining one's

role in an offense is a fact-specific inquiry, 'we rarely reverse

a district court's decision regarding whether to apply a minor

                                     - 49 -
role adjustment.'"             De la Cruz-Gutiérrez, 881 F.3d at 225-26

(quoting United States v. Bravo, 489 F.3d 1, 11 (1st Cir. 2007));

see also United States v. Valenzuela, 849 F.3d 477, 489 (1st Cir.

2017) (reviewing the district court's decision to impose a minor

participant reduction for clear error because "[r]ole-in-the-

offense determinations are notoriously fact-sensitive" (quoting

United States v. Montes-Fosse, 824 F.3d 168, 172 (1st Cir. 2016)));

United     States   v.    Pérez,    819    F.3d   541,    546   (1st   Cir.   2016)

("[B]attles over a defendant's status . . . will almost always be

won   or   lost     in   the    district    court."      (second   alteration   in

original)).       Indeed, "[a] defendant will 'only prevail on appeal

by demonstrating that the district court's determination as to his

role in the offense was clearly erroneous.'" De la Cruz-Gutiérrez,

881 F.3d at 226 (quoting United States v. González-Soberal, 109

F.3d 64, 74 (1st Cir. 1997)).              And our "clear-error standard is

demanding and will be satisfied 'only if, upon whole-record review,

an inquiring court forms a strong, unyielding belief that a mistake

has been made.'"         Mendoza-Maisonet, 962 F.3d at 20 (quoting United

States v. Montañez-Quiñones, 911 F.3d 59, 66 (1st Cir. 2018))

(cleaned up).       What's more, if the record supports at least two

plausible inferences, the district court's choice among these

                                      - 50 -
alternatives     cannot   be    clearly    erroneous.         See   De   la   Cruz-

Gutiérrez, 881 F.3d at 227.32

           All of this to say, "the standard is highly deferential,

and reversal is rare."          United States v. Ruiz, 999 F.3d 742, 750

(1st Cir. 2021) (citing Mendoza-Maisonet, 962 F.3d at 23).

           With this guidance in tow, we turn to the opposing views

presented at the presentencing regarding Andino's role in the

trafficking operation.          After the trial concluded and before the

sentencing     hearing,     a    probation    officer     produced       Andino's

presentence report ("PSR").          The report came up with an initial

offense level of 36 pursuant to U.S.S.G. § 2D1.1(a) and the

application of a two-level reduction according to the safety valve

criteria under U.S.S.G. § 5C1.2, cmt. n.2.33            The probation officer

posited   that   "Ms.     Andino    is    entitled   to   a    mitigating     role

     32 See also U.S.S.G. Notes:   "The determination whether to
apply subsection (a) or subsection (b), or an intermediate
adjustment, is based on the totality of the circumstances and
involves a determination that is heavily dependent upon the facts
of the particular case."
     33 The safety valve provision limits the application of
mandatory minimum sentences for certain drug offenders who qualify
under a list of factors included in 18 U.S.C. § 3553(f). See also
U.S.S.G. § 5C1.2. We have found "Congress's purpose in enacting
the provision was to 'mitigate the harsh effect of mandatory
minimum sentences' on first-time, low-level offenders in drug
trafficking schemes."   United States v. Padilla-Colón, 578 F.3d
23, 30 (1st Cir. 2009) (citing United States v. Ortiz-Santiago,
211 F.3d 146, 150 (1st Cir. 2000)); see H.R. Rep. No. 103-460
(1994).   After Andino's safety valve interview, the government
determined she satisfied the statutory requirements and therefore
agreed to the application of this two-level adjustment.

                                     - 51 -
adjustment" and thus reduced her base offense level by three levels

(meaning she was less culpable than other participants in the

offense but had more than a minimal role) and then reduced it an

additional two levels for being a minor participant.

          The   government   objected   to   the   probation   officer's

application of the two mitigating role adjustments, however the

probation officer stood by his initial determination, stating

Andino's role in the offense "seems to be small when compared to

that of some of her co-conspirators within the overall drug

importation scheme."   The probation officer did not dispute the

events (being present in meetings, signing marina forms, helping

wrap and clean the kilos), but argued a closer look at those

activities reveals the role of a minor participant.             Andino's

sentencing memorandum adopted the probation officer's reasoning,

and in turn proposed to the district court an 87-month sentence,

the lower bound of the sentencing range once adjusted for the

safety valve and both mitigating role adjustments.

          In its ensuing formal objection, the government applied

the five-factor assessment listed in section 3B1.2 cmt. n.3 (C) to

the facts of Andino's case,34 concluding from this exercise that

     34 These five non-exhaustive factors are: (i) the degree to
which the defendant understood the scope of the criminal activity;
(ii) the degree to which the defendant participated in planning or
organizing; (iii) the degree to which the defendant exercised
decision-making authority; (iv) the nature and extent of the

                               - 52 -
Andino was no mere mule or smokescreen within the trafficking

enterprise.       Based on this telling of the story, the government

asked for 120 months' imprisonment.

            With    this   point   of    contention    looming,     the   parties

headed into the sentencing hearing.               Once there, the district

court, after considering arguments from both sides, disagreed with

the probation officer and Andino's position, ultimately finding

Andino ineligible for any mitigating role adjustment.                To justify

its decision, the court went through the five mitigating role

adjustment factors (see supra note 34) and matched Andino's conduct

to each factor.      The district court noted Andino had sailed to St.

Thomas on several occasions, well aware of her role as a "filler"

to cover up the true nature of the voyage.             Prior to at least one

trip to St. Thomas, Andino met at Coplin's home to coordinate and

plan the next criminal venture.          Andino's role while in St. Thomas

-- registering the Black Wolfpack at the Crown Bay Marina and

assisting    in    the   packaging      of   several   kilos   of   cocaine    --

demonstrated her willing participation in the commission of the

crime.      And lastly, as the final factor, the district court

observed that Andino received $7,000 for her participation in a

single trip from which the court inferred Andino stood to benefit

from the criminal activity.

defendant's participation;           and (v) the degree to which the
defendant stood to benefit.          See U.S.S.G. § 3B1.2, cmt. n.3 (C).

                                     - 53 -
             With all the facts on the table, the district court

concluded Andino did not play a minor role in the operations of

the Black Wolfpack and denied the mitigating role adjustments she

requested.     From there, the court landed on a total offense level

of 34, which, when bundled with her criminal history category of

I, yielded a guideline range of 151-188 months.              After noting that

range was greater than necessary to achieve the goals of sentencing

and,    consequently,      adding    a    downward   variance,      the   district

court's tabulations concluded with the pronouncement of a 120-

month sentence of imprisonment and a five-year term of supervised

release.

             Now we assess whether the district court clearly erred

in its decision to deny Andino this adjustment.               Remember, Andino

had    the   burden   of   proving       her   entitlement   to    the    requested

adjustment, Mendoza-Maisonet, 962 F.3d at 23, and we defer to the

district court's factual determinations as to whether she carried

that burden unless we form "a strong, unyielding belief that a

mistake has been made," id. at 20 (quoting Montañez-Quiñones, 911

F.3d at 66).      Viewed under this exacting lens, we spy no such

mistake and conclude Andino's sentencing claim must fail.

             Andino's arguments in support of her overall sentencing

challenge share intertwined theses and themes:                    She carried her

burden of showing she was an inessential "smokescreen" who played

a tiny, non-leadership role in the trafficking scheme and was thus

                                     - 54 -
far less blameworthy than most of her smuggling cohorts, and the

district court committed error in ignoring some evidence and

misconstruing other evidence to reach the opposite conclusion.   We

tease all of this out as we go.

          Let's start with Andino's argument that the court's

denial of her requested adjustment was clearly erroneous35 because

"she was less culpable than most codefendants; the only exception

being codefendant . . . Martínez-Alberto."

          For starters, our case law is clear that all parties

engaged in a criminal enterprise can be "located on a continuum."

Arias-Mercedes, 901 F.3d at 8. Those who are primarily responsible

stand on one end, and the least culpable participants, described

here as being Martínez, stand at the opposite end.           When a

defendant "stands somewhere in the middle," as Andino seems to

concede is where she falls on this continuum, a district court may

reasonably infer the defendant is "not substantially less culpable

than the average participant."    Id.   This fundamentally undercuts

much of her argument.

          Another problem with this asseveration is that it asks

us to simply take a different view of the same facts that were

     35A quick aside to acknowledge the possibility that Andino's
counsel conceded at argument before us that there was no clear
error in the district court's findings.     But because it's not
entirely clear and it's similarly unclear how sweeping the
concession would be, we'll proceed to our analysis.

                             - 55 -
before the district court to reach Andino's preferred outcome.36

This    is    not    a     winning    approach.     See    Pérez,     819   F.3d   546

(dismissing         appellant's       arguments   based     on     the    same   facts

considered by the district court); Mendoza-Maisonet, 962 F.3d at

24 (rejecting appellant's argument that the district court failed

to accurately interpret the facts within the record).                     And despite

Andino's disagreement with the inferences drawn by the district

court,       when    "the    record    supports     at    least    two    permissible

inferences,         'the    sentencing    court's    choice       among   supportable

alternatives cannot be clearly erroneous.'"                 De la Cruz-Gutiérrez,

       And another quick aside on the topic of what, exactly, was
       36

before the district court with respect to Andino because, in her
papers and at oral argument, Andino devoted some attention to her
safety valve interview and the role she thinks it should have
played in sentencing.       In her interview, Andino provided
information about her knowledge and participation in the criminal
enterprise. She says this was presented at sentencing and should
have been considered by the court in determining her role in the
offense.
     Here's the thing. When the district court clearly stated it
would not use this information, opting instead to "strictly
determine her role in the offense based on what was testified at
trial," Andino did not object.     That means our review of this
question is for plain error. See United States v. Pupo, 995 F.3d
23, 29 (1st Cir. 2021). But Andino failed to cite any case law
that requires district courts to consider safety valve interviews
or explain how the information produced in her interview would
help her case. Truth be told, she made no mention of the plain-
error review this aspect of her argument was up against, let alone
attempt to meet the onerous four-part burden. For these reasons,
this aspect of Andino's argument is waived. See Cruz-Ramos, 987
F.3d at 40 (collecting examples of waiver arising when appellants
fail to attempt to meet the demanding burden of plain-error
review).

                                         - 56 -
881 F.3d at 227 (quoting Pérez, 819 F.3d at 546).        That is what we

have here.

          Next consider Andino's supposition that because other

co-defendants had greater organizing roles, the court erroneously

inferred she took part in planning the crime based on testimony

placing Andino at a meeting to plan an operation. Not so. Instead,

when the district court considered these facts, it reasonably

viewed   Andino's   presence     at      the   meeting    as   evidence

"establish[ing] that Ms. Andino possessed some degree of decision-

making authority or that she was sufficiently trusted to be part

of the coordination efforts."   Similarly, Andino argues the $7,000

payout for her role in the operation was insignificant considering

other participants received over $20,000.      When the district court

considered testimony stating Andino received thousands of dollars

for her efforts and $7,000 for a single trip, it inferred "the

financial benefits for participating in the criminal activity were

significant."   We are left with two sides of the same story, and

no reason to find the district court clearly erred in determining

she hadn't carried her burden -- "the fact that someone else might

have been more culpable than [Andino] does not necessarily mean

that [Andino's] participation was minor [or minimal]." De la Cruz-

Gutiérrez, 881 F.3d at 226 (third alteration in original); see

also Mendoza-Maisonet, 962 F.3d at 24-25.

                                - 57 -
             Then there's Andino's argument that the district court

relied too heavily upon the government's position, did not consider

the arguments made by the probation officer, and failed to support

its decision for denying Andino's adjustment with evidence in the

record.      Andino bases this claim on the addendum to the PSR where

the   probation      officer       stood      by   and     doubled    down    on    his

determination that Andino was deserving of a minor role.                            But

despite Andino's insistence that "the sentencing [c]ourt did not

consider them and ultimately sided with the government's version

of the facts," the court made clear it had reviewed the parties'

submissions (including the defense's sentencing memorandum, which

relies upon the probation officer's reasoning in the addendum to

the   PSR)    and   went     on   to     reference       the    probation    officer's

perspective     throughout        the   sentencing       hearing.      Notably,     the

district court concluded that the "probation officer did not

correctly apply the guideline computations, and the pre-sentence

investigation       report   does       not   reflect     the    components    of   Ms.

Andino's offenses, or consider their nature and circumstances."

In other words, and contrary to Andino's argument otherwise, the

court considered both the probation officer's and the government's

views before making a "choice among supportable alternatives," and

we "cannot [find this] clearly erroneous."                     De la Cruz-Gutiérrez,

881 F.3d at 227 (quoting Pérez, 819 F.3d at 546); see also Mendoza-

Maisonet, 962 F.3d at 24 (acknowledging the district court hadn't

                                         - 58 -
explained its decision to deny a minimal participation reduction,

but "infer[ring] that it sided with the [g]overnment's arguments

and therefore decided not to apply the reduction").

           And Andino also invokes the guidelines' commentaries,

alleging   that    the    district     court's      failure      to   follow      these

commentaries      amounted       to   an   incorrect        application      of     the

guidelines.     See, e.g., United States v. Carrasco-Mateo, 389 F.3d

239,   243-44     (1st    Cir.    2004)     ("The     Sentencing       Commission's

commentary, including the application notes, is binding on the

courts as long as it does not conflict either with the sentencing

guidelines themselves or with some statutory provision.").                         Like

the arguments that came before it, this one also fails to move the

needle.    Section 3B1.2, cmt. n.3 (C) establishes the now familiar

non-exhaustive     list    of    factors,    but    also     informs    us     that   a

defendant "who is simply being paid to perform certain tasks should

be considered for an adjustment under this guideline," and an

adjustment remains a possibility even for a defendant who "performs

an essential or indispensable role in the criminal activity."

However, we've observed that "[t]he commentary does not indicate

that   every    such     offender     is   entitled    to    a   mitigating        role

adjustment; it merely instructs that every such offender 'should

be considered for a mitigating role adjustment.'"                 Arias-Mercedes,

901 F.3d at 9 (quoting U.S.S.G. App. C, Amend. 794).                              While

Andino's circumstances could be found to meet this commentary's

                                      - 59 -
parameters, the record shows that the district court considered

Andino's   role   in   the   offense   and   found   it   undeserving   of   a

mitigating role adjustment.       And when, as we've observed, someone

participates "in a hazardous voyage at sea" to move a significant

volume of drugs, "it ordinarily will not be clear error for the

sentencing court to refuse [her] a mitigating role adjustment."

Id. at 8 (citing Pérez, 819 F.3d at 546).            This is an example of

that ordinary no-clear-error case.

           And so, seeing no clear error in the district court's

determination that Andino did not carry her burden to demonstrate

she was entitled to the downward adjustment she sought, we affirm

here as well.

                                CONCLUSION

           Having reasoned through all of the issues leading to the
