    August 25, 2021
    SELYA, Circuit Judge.          A noted British ethologist once
    observed that "[t]he total amount of suffering per year in the
    natural   world    is   beyond   all    decent   contemplation."        Richard
    Dawkins, River Out of Eden 131-32 (Basic Books 1995).                Some of
    this suffering is unavoidable, but some is caused by those who
    callously place profits over principle.          The facts of this mammoth
    case, as supportably found by the jury, tell a chilling tale of
    suffering that did not need to happen.             It involves a group of
    pharmaceutical executives who chose to shunt medical necessity to
    one side and shamelessly proceeded to exploit the sickest and most
    vulnerable among us — all in an effort to fatten the bottom line
    and pad their own pockets.
    The tale told by this case chronicles the pernicious
    practices employed by a publicly held pharmaceutical firm, Insys
    Therapeutics, Inc. (Insys), with respect to the marketing and sale
    of Subsys, a fentanyl-laced medication approved by the United
    States Food and Drug Administration (FDA) for use in the treatment
    of breakthrough cancer pain. When the government got wind of these
    practices,   it    launched   an   investigation.        That   investigation
    produced evidence that led a federal grand jury to indict seven of
    the company's top executives on charges brought under the Racketeer
    Influenced   and    Corrupt      Organizations     Act   (RICO),   18    U.S.C
    § 1962(d).   Two of the executives eventually entered into plea
    agreements, but the rest stood their ground.             Following a fifty-
    - 4 -
    one-day trial, the jury convicted the five remaining defendants as
    charged (with an exception described below), and the district court
    (again with an exception described below) declined to set aside
    the jury verdicts.        The court then sentenced the defendants to
    prison   terms   of     varying    lengths,    ordered   defendant-specific
    restitution, and directed the forfeiture of certain assets.
    On appeal, the defendants — ably represented — raise a
    gallimaufry of claims.        The government cross-appeals, assigning
    error to the district court's refusal to embrace the whole of the
    jury verdicts and to its computation of the forfeiture amounts.
    After careful consideration of an amplitudinous record, we uphold
    the jury verdicts in full, affirm the defendants' sentences (which
    are unchallenged), vacate the restitution and forfeiture orders,
    and remand for further proceedings consistent with this opinion.
    I
    We begin with a snapshot of the relevant facts drawn
    from the evidence adduced at trial.            We then briefly rehearse the
    travel of the case.
    A
    Insys is a pharmaceutical firm founded by one of the
    defendants, Dr. John Kapoor.          Under the Insys umbrella, Kapoor
    sought to develop sublingual spray drug-delivery formulations.
    The   firm   explored    various    options,    but   soon   concentrated   on
    - 5 -
    developing a sublingual fentanyl spray.      This product came to be
    called "Subsys."
    In early 2012, the FDA approved Subsys for the treatment
    of patients suffering from "breakthrough cancer pain."         The term
    "breakthrough cancer pain" is a term of art:       it refers to brief
    spikes in pain (typically lasting less than one hour) in patients
    with cancer who are already dealing with constant and relatively
    steady pain.   All other uses of Subsys were deemed "off-label."
    When Subsys went on the market, its FDA-approved label
    declared that "[t]he initial dose of Subsys to treat episodes of
    breakthrough cancer pain is always 100 micrograms."      Moreover, the
    label warned that "Subsys contains fentanyl," which is a "Schedule
    II controlled substance with an abuse liability similar to other
    opioid analgesics."    Relatedly, the label carried a limitation on
    who could prescribe the drug:   due to "the risk for misuse, abuse,
    addiction and overdose," Subsys could be prescribed "only through
    a restricted program . . . called 'Risk Evaluation and Mitigation
    Strategy'"   (REMS).    This   program   formed   part   of   the   FDA's
    Transmucosal Immediate Release Fentanyl REMS Access Program, which
    required patients, prescribers, and pharmacists to sign a form
    stating that they understood the risks presented by the prescribed
    drug.
    Subsys made its debut in the marketplace in March of
    2012 (shortly after FDA approval was secured).       At that point in
    - 6 -
    time, Kapoor was serving as Insys's executive chairman, Michael
    Babich was serving as its chief executive officer, Shawn Simon was
    serving as its vice president of sales, and Matthew Napoletano was
    serving as its vice president of marketing.
    Around the time of the Subsys launch, Insys assembled a
    marketing team.    It proceeded to provide its sales force with
    access to data that ranked physicians "based on their history of
    prescribing within the opiate market, in particular, the fentanyl
    market."   The ranking system assigned a number between 1 and 10 to
    each doctor — the higher the number the greater the volume of
    prescriptions written.       Salespeople were instructed to target
    doctors ranked 5 or above and to give their "highest attention" to
    those assigned a 10.     They were also told to employ a "switch
    strategy" aimed at persuading prescribers whose patients already
    had been determined to need a similar fentanyl product to jettison
    the similar product in favor of Subsys. Although the only approved
    use for Subsys was for treatment of breakthrough cancer pain, most
    of the prescribers listed in the database were pain-management
    specialists, not oncologists.
    Notwithstanding    Insys's    strategic   plan,   Kapoor   was
    disappointed with initial sales and revenue figures.            He told
    colleagues that it was "the worst f*****g launch in pharmaceutical
    history he's ever seen."     In Kapoor's view, the "main issue" was
    that the majority of patients who started on Subsys would stay on
    - 7 -
    the drug only for the first month and would not refill their
    prescriptions.      Napoletano   hypothesized   that   patients   were
    electing not to stick with Subsys because insurance companies were
    choosing not to cover it.   Patients, he suggested, did not want to
    pay out of pocket to refill Subsys prescriptions.
    Kapoor, though, had a different take:    he attributed the
    widespread failure to refill Subsys prescriptions to patients
    "starting on too low of a dose."         Because the Subsys label
    specified the initial dose as 100 micrograms, Kapoor expressed
    concern that patients who were used to a higher dose of a competing
    product would not be satisfied with the pain management offered by
    Subsys at that initial dosage.    Consistent with Kapoor's concerns,
    sales data (which Insys executives analyzed daily) showed that the
    lower a patient's starting dose, the higher the "falloff rate."
    By the fall of 2012, Insys had begun to overhaul its
    marketing team.    Shawn Simon was cashiered, and Alec Burlakoff
    (previously a regional manager) replaced him as vice president of
    sales.   Defendant Joseph A. Rowan was promoted into Burlakoff's
    former role.     Defendants Sunrise Lee and Richard M. Simon were
    installed as regional managers, and defendant Michael J. Gurry
    became vice president for managed markets.1
    1 To avoid any confusion between Richard Simon and Shawn
    Simon, we subsequently refer to Richard Simon — and only Richard
    Simon — as "Simon."
    - 8 -
    In addition to these               executive-suite changes, Insys
    revamped its sales and marketing strategy.             That fall, it hosted
    both a national sales meeting and a national sales call to train
    its sales force on a "new plan of attack."             This plan had several
    components:
    •   A new "switch program" allowed patients who were
    transitioning to Subsys from a competing drug to
    receive vouchers to defray the cost of Subsys for
    as long as they needed it or until it was covered
    by their insurance.
    •   A new "super voucher" program offered a means of
    providing free product to patients.
    •   A    specially     crafted    "effective   dose"    message
    informed prescribers that, despite the statements
    on     the    FDA-approved    labelling,   100-    or    200-
    microgram doses were not effective.         To complement
    this         "effective      dose"    messaging,        sales
    representatives were notified "each and every time"
    a prescriber wrote a Subsys prescription for 100-
    or 200-micrograms; and they           were instructed to
    report back within 24 hours both as to the reason
    why the doctor had prescribed the low dose and as
    to how the doctor planned to titrate the patient to
    the "effective dose."
    - 9 -
    •   A revised compensation structure was put in place.
    This structure rewarded sales representatives for
    pushing   doctors    to    prescribe    higher    doses     of
    Subsys.   Under it, larger prescribed doses yielded
    salespeople   larger      bonuses    both   because      bonus
    percentages   were   higher    for     higher    doses    and
    because higher doses were more costly.
    The icing on the cake was Insys's inauguration of a
    speaker program in August of 2012.        The ostensible "objective of
    the program" was to provide "peer-to-peer education."              To that
    end, Insys would invite physicians whom it envisioned as potential
    Subsys prescribers and the speaker (a fellow health-care provider)
    would "present the information [about the drug] to them."             These
    presentations would take place through "online web hosting[s]" or
    at "dinner meetings."     Each sales region was to host a roughly
    equal number of programs.
    In its original incarnation, the speaker program never
    got off the ground.   Instead, Kapoor transmogrified it.           About a
    month after Napoletano announced the inauguration of the program,
    Kapoor "put on hold all speaker programs effective immediately."
    This directive emanated from Kapoor's disagreement with Napoletano
    about what the objective of the program ought to be:             as Kapoor
    saw it, the speaker program "was designed for the speakers," not
    - 10 -
    for the physicians who comprised the audience.      Kapoor "wanted
    every speaker to write" Subsys prescriptions.
    To accomplish this objective, Kapoor asked Napoletano
    for a list of the doctors who served as speakers, along with data
    as to "how many of them were writing [Subsys]" and data as to "what
    percentage of the prescriptions came from them."        Napoletano
    balked, responding that "it's the attendees that you measure" —
    not the speakers.   Kapoor "was not in agreement with that" and
    continued to insist upon a restructuring of the program.
    In September, Kapoor, Burlakoff, Babich, and Napoletano
    met to discuss the direction of the speaker program.    Consistent
    with Kapoor's vision, Burlakoff argued against the original peer-
    to-peer education model.    When Napoletano pointed out that "in
    accordance with pharma code" each event had to have "a minimum of
    two to four people" attend, Burlakoff replied that he "d[idn't]
    care if there are any attendees" and that "he expect[ed] every
    speaker to write" prescriptions.   He said that the speaker program
    should be "about the speaker and getting return from the speaker."
    Although the meeting "was very contentious," Kapoor was satisfied
    that his message had been received and proceeded to lift his "hold"
    on the speaker program.
    Burlakoff then emailed the sales force stating that
    speaker programs are "the number one opportunity to grow [their]
    business."   He predicted that "[t]he hungry, motivated sales
    - 11 -
    representatives will be facilitating as many speaker programs as
    humanly possible."    He also suggested that a successful speaker
    program would require salespersons to seek out speakers who are
    "expert[s] with the utilization of Subsys in [their] clinical
    practice" and who "have at least 20 patients on Subsys."
    Even with this sharp change in direction, Insys's top
    brass disagreed as to how to measure the program's success.       In
    October, Kapoor, Napoletano, Babich, and Burlakoff met regarding
    that issue.    Napoletano wanted to "track [the attendees] moving
    forward to see if the presentation had any impact and if they
    adopted the product in their practice."    Burlakoff disagreed and
    reiterated that "the metric to track is the speaker."   The meeting
    concluded with the issue still up in the air.
    At a subsequent meeting, Kapoor resolved the issue.   He
    stated that he "wanted to make sure every speaker wrote" Subsys
    prescriptions and "wanted a positive ROI" — a shorthand reference
    to return on investment.   The ROI, as Kapoor measured it, would be
    the ratio between net revenue and the amount paid for speaker
    services.     After a heated exchange, Napoletano capitulated and
    agreed to begin preparing reports tracking speakers and their
    corresponding ROIs.     These reports allowed Kapoor to "see how
    successful [the] speakers were and how much product they were
    writing, based on how much money [Insys] had given them so far."
    Once this data became available, any speaker who "did not generate
    - 12 -
    at least two times in revenue what was being paid to them" was
    "flagged" for a "temporary hold on programming."     Refined to bare
    essence, the flagged speakers "wouldn't get programs" and, thus,
    would not receive honorariums.
    This new protocol transformed the speaker programs from
    pedagogical exercises into funding mechanisms for a pay-for-play
    fandango.      It is, therefore, unsurprising that with the new
    protocol in place, Burlakoff sought to identify "whales."         He
    coined the term "whales" to refer to physicians who "ha[d] agreed
    in a very clear and concise manner that they [were] up for the
    deal, which [meant that] they [would] be compensated based on the
    number of prescriptions of Subsys they wr[ote]."      A corollary to
    that deal was that "the more they wr[ote] and the more they
    increase[d] the dose, the more they'[d] get paid to speak."       At
    Burlakoff's urging, regional sales managers were to have a "candid
    conversation" with each potential whale and make clear that if the
    physician was going to receive payments from Insys, he was "going
    to write a significant amount of Subsys prescriptions to new
    patients as well as increase the doses of current patients."
    Burlakoff told sales managers to view speakers as their "business
    partner[s]."
    Burlakoff's whale hunt was fruitful:   he identified many
    whales, including Drs. Mahmood Ahmad, Gavin Awerbuch, Steven Chun,
    Patrick Couch, Paul Madison, Judson Somerville, and Xiulu Ruan.
    - 13 -
    These prescribers were frequently mentioned on the daily 8:30 a.m.
    management calls, in which Kapoor, Babich, Napoletano, Burlakoff,
    and Gurry regularly participated.     All of the whales committed to
    prescribing large quantities of Subsys.      And if a whale failed to
    meet prescription expectations, an Insys representative would put
    pressure on him to get him back on track.
    Without exception, the prescription numbers of these
    physicians increased when they joined the speaker program.      In an
    email, Burlakoff described the doctors as "clueless" because they
    "prescribe strictly based on their relationship with the sales
    manager."    As a result of that relationship and the pressure that
    sales   representatives    exerted,   practitioners   designated   as
    "[s]peakers" generated approximately $4,200,000 in net revenue (60
    percent of Insys's total net revenue) after receiving more than
    $550,000 in speakers' fees.      Pleased with the success of the
    reconstituted speaker program, Kapoor raised the speaker budget in
    subsequent years.
    Insys allocated speaker programs primarily to whales and
    other prolific Subsys prescribers.      These practitioners were paid
    between $1,000 and $3,000 per event, depending on the particular
    practitioner's "résumé or . . . influence."       Speakers' payments
    were routinely sent by mail.   Multiple speaker events featured the
    same practitioner.   Insys initially capped annual speaking fees at
    $100,000 per practitioner but later raised the ceiling to $125,000.
    - 14 -
    At a meeting in January of 2014, Babich, Burlakoff, and Richard
    Simon compiled a list of "doctors that had the highest potential
    to write."      Burlakoff then "mobilized the sales force to go out
    and make sure that these 19 or 20 doctors reached their [fees]
    cap."
    Despite the largess shown to speakers, the speaking
    events themselves had little to no attendance.                Often, only the
    speaker, a friend or family member, and the sales representative
    were on hand.        Even when more people were in attendance, the
    speaker programs were mostly "social outings" or "just a reason to
    gather people and have dinner and pay [the doctor]."                   Although
    sales representatives were required to submit sign-in forms and
    attendee evaluation forms to a third-party compliance firm (Sci
    Medica),      they   frequently      submitted   inaccurate    documentation,
    including sign-in sheets with names and signatures of people who
    were    not   present,   to   give    the   speaking   programs   an   aura   of
    legitimacy.      And when Kapoor replaced Sci Medica with an in-house
    compliance officer, the apocryphal documentation continued to
    flow.
    While the revamped speakers' program drove up the volume
    of Subsys prescriptions, insurance coverage remained a problem.
    Medicare, Medicaid, and private insurance companies covered the
    cost of Subsys prescriptions only if a practitioner obtained prior
    authorization to prescribe the drug. And because of the FDA label,
    - 15 -
    coverage was limited to patients with a current cancer diagnosis
    who both suffered from breakthrough cancer pain and already had
    tried other opioid medication.
    Nor did the coverage limitations stop there.                     As a
    condition precedent to coverage, insurers required that a patient
    had tried a generic fentanyl product that had either failed to
    ameliorate the breakthrough cancer pain or proved difficult to
    ingest.     To seek prior authorization, a practitioner typically
    submitted patient and diagnosis information to the insurer, and
    the insurer relied upon the accuracy of the submitted information
    in its decisionmaking.       When Insys launched Subsys, it processed
    prior authorization requests through a third party and achieved
    only   a   30-35   percent    success    rate     for    prior    authorization
    approvals.
    To enhance the approval rate, Gurry suggested bringing
    the approval process in-house. With Kapoor's blessing, Gurry hired
    Elizabeth    Gurrieri   in    October    of     2012    to   found     the   Insys
    Reimbursement      Center    (IRC),     which    operated        out   of    Insys
    headquarters.      Insys created an opt-in form through which Subsys
    prescribers could authorize the IRC to contact insurers and request
    prior authorizations.        The form listed patient information that
    insurers typically would request during the prior authorization
    process, such as whether the patient had tried certain medications.
    Particular items from the list could be checked off as applying to
    - 16 -
    a specific case. This streamlined the process: a prescriber would
    sign and fax an opt-in form to the IRC; the IRC would call the
    insurer; and if the insurer needed additional information, the IRC
    would reach out to the sales representative who would then follow
    up with the prescriber.        Insys encouraged physicians to use the
    IRC, knowing that if the prior authorization was approved, "[t]he
    sales rep would get paid, Insys would get paid, and the script
    would get paid."   A pilot program achieved an approval rate of 65-
    70 percent.   As a result, Insys quickly transitioned the IRC out
    of its pilot phase and expanded it.            Gurrieri was promoted to
    manager of reimbursement services in March of 2013.
    The IRC proved to be a rousing success.          It owed much of
    its success to the sales representatives.             They interacted with
    the physicians and collected documentation requested by insurers
    during the prior-authorization process.             A sales representative
    would often spend at least one day per week in a physician's
    office, reviewing patient files, assisting with authorizations,
    and completing the opt-in forms.
    Another factor in the IRC's success was the hiring of
    "area business liaison[s]."       These individuals were assigned to
    the physicians who prescribed Subsys in substantial volume.               Each
    area business liaison worked in a physician's office processing
    authorizations,    but   was   paid   by   Insys,    thereby   reducing   the
    physician's overhead.
    - 17 -
    The third, and perhaps most impactful, factor in the
    IRC's success was Insys's decision to begin collecting data on
    each   coverage   decision.      The   IRC    identified    diagnoses   and
    conditions that historically had prompted particular insurers to
    approve Subsys prescriptions. It proceeded to list these diagnoses
    and conditions on the opt-in form, and sales representatives
    encouraged    physicians    to   employ      them   when   seeking   Subsys
    authorizations.    For example, Gurrieri noted success using "the
    terminology 'history of cancer,' which means that they didn't have
    cancer at the time but they had a history of cancer."                   Once
    salespeople heard that use of that phrase could help obtain
    insurance approval, the IRC, "all of a sudden, saw more opt-ins
    having 'history of cancer' on them, which [led] to better approval
    ratings."
    Management regularly discussed the IRC on the daily 8:30
    a.m. calls.    All updates about the IRC were communicated by Gurry
    during those calls.        Although Insys had made great strides in
    upping its approval rate, Kapoor put constant pressure on the IRC
    to achieve a rate of 90 percent or higher.             Striving to attain
    this benchmark, the IRC started to offer training sessions to sales
    representatives on "how to get the drug approved."              Similarly,
    Gurry started to advise sales representatives about what diagnoses
    and conditions should be checked on the opt-in forms.          He famously
    directed IRC employees "to ride the gray line," that is, to "work
    - 18 -
    around   the    insurance    companies"    and    "find    ways    around   their
    questions."         Following     that    direction,      the     IRC   developed
    strategies to mislead insurers into granting prior authorizations
    for   the    use   of   Subsys.    Some    of    these    strategies     included
    misleading the insurer into believing that the caller was calling
    from the physician's office rather than from the IRC; representing
    that a patient had          cancer even if the available information
    reflected only a history of cancer; giving the ICD-9 diagnosis
    code as "338" to obscure the fact that the diagnosis was chronic
    pain (which uses code 338.29 or 338.4) and not cancer pain or
    neoplasm-related pain (which uses code 338.3); listing tried-and-
    failed medications that the patient had never used; and falsely
    stating that patients had dysphagia (difficulty swallowing).
    Insys expected insurance companies to ask whether a
    physician had prescribed Subsys to treat "breakthrough cancer
    pain."      Gurrieri instructed IRC staff to respond with "the spiel,"
    which was pat phrasing designed to obfuscate the purpose of the
    prescription.      The essence of the spiel was that "[t]he physician
    is aware that the medication is intended for the management of
    breakthrough pain in cancer patients, and the physician is treating
    the breakthrough pain."         Phrased in this way, the expectation was
    that "the person on the other end of the phone would be misled to
    think the patient had cancer and approve the prior authorization."
    - 19 -
    The record makes manifest that the IRC, in practice, was
    more interested in transmitting information that would prompt
    favorable coverage determinations than it was in transmitting
    accurate information.           Through the IRC, the insurers were fed a
    steady diet of deceptions, evasions, and half-truths.
    Just as sales representatives were incentivized to push
    physicians to prescribe higher doses of Subsys, IRC staffers were
    incentivized to obtain insurance approvals. Goals known as "gates"
    were set weekly.      If the gate was opened, the staff member (usually
    paid a low hourly wage) would receive a bonus.
    The cocktail that Insys had mixed — including its revised
    marketing and sales strategies, its use of speaker programs as
    vehicles for bribes to physicians, its use of business liaisons,
    and its no-holds-barred tactics within the IRC — proved to be
    lucrative.      Insys     was    able    to   go   public    only   a   year   after
    introducing Subsys to the market.                  Within two years after the
    initial public offering, the company reached a market cap of over
    $3,000,000,000.       And by the end of 2015, Insys's stock price had
    nearly      quadrupled.          Throughout,        the     defendants     received
    substantial salaries, bonuses, and stock options.
    But Insys's meteoric rise appeared too good to be true,
    and   the   company    attracted        unwanted    attention.      When    federal
    authorities began probing the details of how Insys was marketing
    Subsys, the defendants' scheme began to unravel.

    B
    In the wake of the federal investigation, a federal grand
    jury sitting in the District of Massachusetts charged Kapoor, Lee,
    Simon, Gurry, and Rowan with conspiracy to distribute Subsys
    through    a    pattern    of   racketeering   activity.2      See    id.    The
    conspiracy was effected, the indictment said, through acts of mail
    fraud, see id. § 1341; honest-services mail fraud, see id. §§ 1341,
    1346; wire fraud, see id. § 1343; honest-services wire fraud, see
    id. §§ 1343, 1346; and Controlled Substances Act (CSA) violations,
    see   
    21 U.S.C. § 841
    (a)(1).        Following     lengthy    pretrial
    maneuvering, not relevant here, a fifty-one-day trial ensued.
    The jury returned guilty verdicts against all of the
    defendants.       In connection with those verdicts, the jury made a
    series of special findings that all the defendants were guilty of
    committing predicate acts of mail-fraud and wire-fraud, and that
    all the defendants (except Gurry) were guilty of agreeing to
    distribute a controlled substance and to commit honest-services
    mail fraud and honest-services wire fraud.
    The defendants moved for judgments of acquittal and/or
    new trials.      See Fed. R. Crim. P. 29(a), 33(a).       The district court
    granted in part the joint motion for judgments of acquittal filed
    by Kapoor, Lee, Simon, and Rowan, vacating as to them the adverse

    of them entered guilty pleas before trial.

    findings with respect to the CSA and honest-services predicates.
    See United States v. Gurry, 
    427 F. Supp. 3d 166
    , 222 (D. Mass.
    2019). But with respect to all five defendants, the court rejected
    their challenges to the mail- and wire-fraud predicates, rejected
    their efforts to secure judgments of acquittal, and declined to
    order a new trial.     See 
    id.
       The court sentenced the defendants to
    terms of immurement of varying lengths and entered a series of
    restitution and forfeiture orders.3           See United States v. Babich,
    No. 16-CR-10343, 
    2020 WL 1235536
    , at *10 (D. Mass. Mar. 13, 2020).
    All of the defendants appealed, and the government cross-appealed.
    II
    In this venue, we are faced with a kaleidoscopic array
    of claims. Kapoor, Lee, Simon, and Rowan contend that the evidence
    was insufficient to convict on the various mail- and wire-fraud
    predicates, assigning error to the district court's denial of their
    joint motion for judgment of acquittal.          Relatedly, all defendants
    claim    error   in   the   admission    of   patient-harm   testimony   and
    3 The court sentenced Kapoor to a sixty-six-month term of
    immurement, ordered restitution of $59,755,362.45, and directed
    forfeiture of $1,914,771.20. As to Lee, the court imposed a prison
    sentence of a year and a day, ordered restitution of $5,000,000,
    and directed forfeiture of $1,170,274.     As to Simon, the court
    imposed a thirty-three-month term of immurement, ordered
    restitution   of   $5,000,000,    and   directed   forfeiture   of
    $2,338,078.72. Gurry's sentence was identical to Simon's, except
    that he was ordered to forfeit $3,390,472.89. Finally, the court
    sentenced Rowan to serve a twenty-seven-month prison term, ordered
    restitution   of   $5,000,000,    and   directed   forfeiture   of
    $2,078,217.66.

    prejudicial spillover arising out of the government's efforts to
    prove       the     CSA     and    honest-services    predicates       through   that
    testimony.
    Some defendants raise individual claims as well.                    Lee
    challenges the district court's order denying her pretrial motion
    for    severance,          certain    of   the   district    court's     evidentiary
    rulings, and one of the district court's jury instructions.                      Rowan
    claims       that     the     government     unlawfully     withheld     exculpatory
    material, and that the district court erred in denying his mid-
    trial       motion    to     compel    production    of   that    material.        The
    defendants, jointly and severally, offer a plethora of reasons as
    to why they — or some of them — ought to be granted new trials,
    including claims relating to allegedly conflicted counsel, weight
    of    the    evidence,       and    prosecutorial    misconduct    during    closing
    arguments.4          And although the defendants do not challenge their
    4At various points, some of the defendants purport to
    incorporate by reference arguments made by other defendants. See
    Fed. R. App. P. 28(i). For example, a footnote in Rowan's brief
    purports to "adopt[] and incorporate[] the facts and arguments in
    the briefs of co-defendants Dr. John Kapoor, Richard Simon, Michael
    Gurry, and Sunrise Lee, whether or not this brief explicitly
    mentions them." Lee's and Gurry's briefs each contains similar
    statements.
    The   rule   in   this  circuit   is   that   "[a]doption   by
    reference . . . cannot occur in a vacuum; to be meaningful, the
    arguments adopted must be readily transferrable from the
    proponent's case to the adopter's case." United States v. David,
    
    940 F.2d 722
    , 737 (1st Cir. 1991). Given this rule, the shorthand
    adoption by reference attempted by these defendants is partially
    an empty gesture.     And to the extent that the incorporated
    arguments pass through this screen, they fail on the merits (except
    - 23 -
    prison sentences, they do contest the district court's ancillary
    orders awarding restitution and forfeiture.          The government cross-
    appeals, assigning error to the district court's order vacating
    the jury's findings adverse to Kapoor, Lee, Simon, and Rowan on
    the CSA and honest-services predicates.               It also appeals the
    district court's calculation of forfeiture amounts with respect to
    Lee, Simon, Gurry, and Rowan.
    We start our journey with the parties' competing claims
    concerning the sufficiency of the evidence with respect to the CSA
    and honest-services predicates.             From there, we wend our way
    through   the   remaining    sufficiency-of-the-evidence         claims,    the
    admissibility of the patient-harm testimony, questions pertaining
    to evidentiary spillover, and a myriad of other claims of trial
    error. Our journey ends with an appraisal of the parties' opposing
    views regarding issues related to restitution and forfeiture.
    III
    Under RICO, it is a crime "for any person employed by or
    associated with any enterprise engaged in, or the activities of
    which affect, interstate or foreign commerce," to conspire "to
    conduct or participate, directly or indirectly, in the conduct of
    such   enterprise's   affairs    through      a   pattern   of   racketeering
    activity."      See   
    18 U.S.C. § 1962
    (c),    (d).     A    pattern   of
    with respect to certain incorporated arguments, identified in
    Parts XIV and XV, infra, regarding restitution and forfeiture).
    - 24 -
    racketeering activity requires at least two predicate racketeering
    acts within ten years of each other.       See 
    id.
     § 1961(5).       A
    defendant need not have "agree[d] to commit or facilitate each and
    every part of the substantive offense" in order to be found guilty.
    Salinas v. United States, 
    522 U.S. 52
    , 63 (1997).       Nor need such
    a defendant be capable of committing the substantive offense.     See
    
    id.
     Instead, "[a]ll the government need show is that the defendant
    agreed to facilitate a scheme in which a conspirator would commit
    at least two predicate acts, if the substantive crime [had]
    occurred."   United States v. Rodríguez-Torres, 
    939 F.3d 16
    , 29
    (1st Cir. 2019); see Salinas, 
    522 U.S. at 65
     ("A [RICO] conspirator
    must intend to further an endeavor which, if completed, would
    satisfy all of the elements of a substantive criminal offense, but
    it suffices that he adopt the goal of furthering or facilitating
    the criminal endeavor.").
    In this case, the critical questions involve whether —
    as to each defendant — the record sufficiently supports the jury's
    verdict that he or she, directly or through another conspirator,
    committed the charged offenses.     While the jury answered these
    questions in the affirmative (except as to Gurry, who was found
    guilty only with respect to the mail- and wire-fraud predicates),
    the district court found the government's proof of the CSA and
    honest-services   predicates   wanting.   The   court    ruled   that,
    although "it would not have been unreasonable for the jury to infer
    - 25 -
    that the nefarious tacit understanding the Government describes
    existed," it "would have been equally reasonable for the jury to
    infer from the same evidence that no such tacit understanding
    existed."   Gurry, 427 F. Supp. 3d at 186.   Because the proof "gives
    equal or nearly equal circumstantial support to a theory of guilt
    and a theory of innocence," the court vacated the jury findings
    regarding the CSA and honest-services predicates vis-à-vis Kapoor,
    Lee, Simon, and Rowan.   Id. (quoting United States v. Burgos, 
    703 F.3d 1
    , 10 (1st Cir. 2012)).
    The government appeals from this ruling.     Our task is
    familiar. We afford de novo review to the district court's rulings
    on the defendants' joint motion for judgment of acquittal.       See
    United States v. Kilmartin, 
    944 F.3d 315
    , 325 (1st Cir. 2019);
    United States v. Olbres, 
    61 F.3d 967
    , 970 (1st Cir. 1995).   "Where,
    as here, the defendant[s] challenge[] the sufficiency of the
    evidence, all of the proof 'must be perused from the government's
    perspective.'"   Kilmartin, 944 F.3d at 325 (quoting United States
    v. Gomez, 
    255 F.3d 31
    , 35 (1st Cir. 2001)).        This lens demands
    that "we scrutinize the evidence in the light most compatible with
    the verdict, resolve all credibility disputes in the verdict's
    favor, and then reach a judgment about whether a rational jury
    could find guilt beyond a reasonable doubt."      Olbres, 
    61 F.3d at 970
     (quoting United States v. Taylor, 
    54 F.3d 967
    , 974 (1st Cir.
    1995)).
    - 26 -
    In conducting this tamisage, "we must honor the jury's
    evaluative choice among plausible, albeit competing, inferences."
    United States v. Rodríguez-Vélez, 
    597 F.3d 32
    , 40 (1st Cir. 2010).
    When all is said and done, "[t]he court need not be convinced that
    the verdict is correct; it need only be satisfied that the verdict
    is   supported        by    the   record."       Kilmartin,    944    F.3d   at   325.
    Consequently, a "verdict must stand unless the evidence is so scant
    that a rational factfinder could not conclude that the government
    proved all the essential elements of the charged crime beyond a
    reasonable doubt."            Rodríguez-Vélez, 
    597 F.3d at 39
     (emphasis in
    original).
    Our next chore is to elaborate the elements of the CSA
    predicates.       The CSA makes it a crime "for any person knowingly or
    intentionally . . . to manufacture, distribute, or dispense . . . a
    controlled substance."             
    21 U.S.C. § 841
    (a)(1).         Even so, licensed
    health-care practitioners (typically, physicians) registered under
    the CSA are authorized to dispense controlled substances.                    See 
    id.
    § 822(b).        This authorization, though, is not absolute.                     Such
    practitioners face criminal liability "when their activities fall
    outside the usual course of professional practice."                    United States
    v.   Moore,      
    423 U.S. 122
    ,   124   (1975);   see   United     States    v.
    Limberopoulos, 
    26 F.3d 245
    , 249 (1st Cir. 1994) ("[T]he statute
    applies     to    a    pharmacist's        (or     physician's)      drug-dispensing
    activities so long as they fall outside the usual course of
    - 27 -
    professional practice.").      Because a RICO conspiracy conviction
    requires proof that defendants "specifically intended that some
    conspirator commit each element of" the predicate racketeering
    acts, Ocasio v. United States, 
    136 S. Ct. 1423
    , 1432 (2016)
    (emphasis in original), the government had to prove that the
    defendants specifically intended          that   a     licensed practitioner
    would   prescribe   Subsys   "with   no   legitimate      medical   purpose,"
    United States v. Volkman, 
    797 F.3d 377
    , 391 (6th Cir. 2015); see
    United States v. Feingold, 
    454 F.3d 1001
    , 1008 (9th Cir. 2006).
    Against this backdrop, we canvass the proof as to Kapoor,
    Lee, Simon, and Rowan.
    A
    Through his motion for judgment of acquittal, Kapoor
    challenged, inter alia, the jury's finding that he was guilty of
    conspiracy to commit racketeering activities through a pattern of
    racketeering   acts   that   included     the    CSA    and   honest-services
    predicates.    As we have said, the district court set aside the
    jury's findings with respect to those predicates.             The question is
    one of evidentiary sufficiency.
    The record is replete with support for the proposition
    that Kapoor intended physicians to write medically illegitimate
    prescriptions.      Kapoor sought out pill mill doctors (that is,
    doctors who were notorious for their readiness to prescribe drugs
    regardless of medical necessity).          See, e.g., United States v.
    - 28 -
    Iriele, 
    977 F.3d 1155
    , 1161 (11th Cir. 2020) (describing as "pill
    mill" a clinic where people "could get prescriptions for their
    controlled    substances        of    choice    with     few,    if    any,    questions
    asked").     For instance, Burlakoff testified that, to increase
    sales, Kapoor wanted him to do "[w]hatever it took with whomever
    [they] called on, including pill mill doctors."
    Perhaps the best illustration of Kapoor's intent is
    found in the evidence concerning his attitude toward Dr. Madison.
    Kapoor    encouraged      dealings       with     Dr.    Madison       despite    having
    reviewed an email in which a sales representative wrote that "Dr.
    Madison     runs     a   very        shady   pill       mill     and    only     accepts
    cash. . . .    He basically just shows up to sign his name on the
    prescription pad, if he shows up at all."                      Kapoor also knew that
    another sales representative had observed a "shady setup" in Dr.
    Madison's office with "many patients . . . going in and out of
    there . . . just seeking medication."                   As one expert witness put
    it, this prescribing behavior was inconsistent with a doctor's
    duty to carry out "those things that are necessary to reasonably
    diagnose     the    problem,"         such   as     "history      taking,      physical
    examination,       and   the    obtaining       and     evaluation      of    diagnostic
    studies."
    Although on unmistakable notice of the kind of operation
    that Dr. Madison appeared to be running, Kapoor pursued him.
    Babich testified that Kapoor "wanted [Dr. Madison] to write the
    - 29 -
    drug" and awarded him speaker programs (and, thus, kickbacks) "as
    much as once a week."            This was consistent both with Babich's
    description    of     Kapoor's    avowed    "philosophy"    and   with    other
    evidence   reflecting      Kapoor's    appetite   for   whales.     The    jury
    reasonably could have found that Kapoor's decision to continue
    courting     and     compensating     Dr.   Madison,    notwithstanding     his
    knowledge that the doctor was running a notorious pill mill, was
    proof of at least a tacit understanding of Kapoor's culpable role
    in the distribution scheme.          See United States v. King, 
    898 F.3d 797
    , 809 (8th Cir. 2018).
    Kapoor complains that this is a bridge too far.                   He
    laments that he received hundreds of emails a day, that he was
    busy with other business pursuits and charitable endeavors, and
    that Dr. Madison is only one of 13 doctors discussed in the four-
    page email.        It follows, Kapoor suggests, that a reasonable jury
    could not infer that he read the sales representative's description
    of Dr. Madison.
    This suggestion is little more than whistling past the
    graveyard.    It conveniently overlooks that the jury heard evidence
    that Kapoor demanded information on "every [Subsys] script that
    was written" and "every doctor that wrote it."                    He demanded
    spreadsheets to parse doctor-level data and sought to identify
    "whales" — doctors who understood that, in exchange for speaker-
    - 30 -
    program payments, they would prescribe "a significant amount of
    Subsys prescriptions."
    What is more, Babich testified that Kapoor expressed
    great interest in these kinds of sales reports.    Kapoor "want[ed]
    every single rep every Friday to e-mail [Babich] a list of all
    their top physicians and what happened with those top physicians
    that week."   An assistant "print[ed] these out" and put "them on
    [Kapoor's] desk for Monday morning, so he c[ould] review" them.
    Given that level of attention to detail vis-à-vis prescribers, the
    inference that Kapoor read the email about Dr. Madison seems
    compelling.
    Last — but surely not least — Babich confirmed that he
    gave the four-page email directly to Kapoor.      He also testified
    that — several months after he had forwarded that email about Dr.
    Madison to Kapoor — the same sales representative again reiterated
    that Dr. Madison operated a pill mill and added that Dr. Madison
    faced possible legal action.     Babich described this matter as "a
    serious issue" and testified that he personally reviewed this
    information with Kapoor.    Kapoor responded that Dr. Madison "still
    has a medical license.     I don't want him taken off the call list"
    for speaker programs.
    We need not tarry.      The evidence, taken in the light
    most hospitable to the verdict, plainly supports the inference
    that Kapoor knew of Dr. Madison's illegitimate prescribing habits
    - 31 -
    yet took steps to ensure that he would continue prescribing Subsys.
    Indeed, the evidence warrants an inference that Kapoor sought to
    recruit Dr. Madison as a speaker (that is, as a kickback recipient)
    precisely because of these habits. Such an inference is consistent
    with other evidence that pill mill doctors were prized by Kapoor:
    he   tracked   physicians'   prescription    patterns,   gave   favorable
    treatment to the doctors who prescribed Subsys most profligately,
    and — according to Burlakoff — did "whatever it took" to increase
    Subsys sales.    As Burlakoff put it, Kapoor's message to the sales
    force was that "pill mills for [Insys] meant dollar signs."
    The evidence also showed that Kapoor led Insys's effort
    to influence physicians' prescription decisions through "effective
    dose" messaging. The FDA-approved label stated that "[t]he initial
    dose of Subsys to treat episodes of breakthrough cancer pain is
    always 100 micrograms."      Doctors were supposed to "look at one
    patient at a time" and "titrate one patient at a time" to the dose
    of the drug that achieves "the desired effect."             Noting that
    patients on higher doses were more likely to refill their Subsys
    prescriptions, Kapoor sought to ride roughshod over this regime
    and "move patients to higher doses."        His mantra was to "push the
    dose."   To that end, he incorporated into the speaker program
    kickbacks for dosage increases — the greater the increase, the
    greater the payout.     Predictably, Kapoor's campaign to increase
    dosages resulted in the sales force negotiating dosage agreements
    - 32 -
    with doctors.       And Insys closely monitored these agreements:             for
    example, when Dr. Somerville's dosage numbers appeared to be low,
    a sales representative was instructed to "[d]rill into [the medical
    assistant's]    head    that    every   refill   has    to   be    180   to   240
    [micrograms]" because "Dr. Somerville agreed to do this."
    To sum up, the evidence plainly supports a finding that
    Kapoor intended practitioners to prescribe Subsys as much as
    possible, even when there was no medical necessity for the drug or
    the dosage prescribed.        His "effective dose" campaign was designed
    to dissuade doctors from prescribing medically appropriate lower
    dosages and to accelerate dose titration.            A reasonable jury could
    infer that, by taking these actions, Kapoor pushed physicians — in
    Burlakoff's words — to "initiate a new habit" that would transform
    patients     into    repeat    customers,    quite     apart      from   medical
    necessity.    See United States v. Clough, 
    978 F.3d 810
    , 820-21 (1st
    Cir. 2020) (concluding that giving "opioid-dependent patients high
    dosages of this highly-addictive fentanyl drug, even when patients
    had no problems with their existing regimen" supported reasonable
    inference that defendant's "behavior was not reminiscent of a
    physician assistant prescribing based on need, but rather [that]
    of a drug pusher").       And having thrown medical necessity to the
    wind, Kapoor's "push the dose" message effectively directed Insys
    salespersons, who were not health-care professionals, to enforce
    mandatory ranges of dosages.       Following Kapoor's lead, they shaped
    - 33 -
    doctors' prescription decisions without regard to any individual
    patient information by getting the doctors to commit to meeting
    prescription-quantity numbers on a weekly basis.                  Jurors are
    allowed to use common sense and — surveying this unattractive
    tableau — a reasonable jury could have inferred that Kapoor, in
    "push[ing] the dose," intended doctors to increase doses of Subsys
    regardless of who the patient was or what the patient's medical
    needs might be.      See United States v. Guzman, 
    571 F. App'x 356
    ,
    363 (6th Cir. 2014) ("[T]he jury could reasonably infer the
    requisite agreement to distribute controlled substances, as well
    as   knowledge    and     participation"    from   "evidence   showing    that
    [defendants] tried to modify the prescribing practices of another
    nurse practitioner," including by directing a "nurse to prescribe
    short-acting rather than long-acting medications and to prescribe
    prednisone for all customers.").
    So, too, a reasonable jury could conclude that when drug
    wholesalers reported suspicious Subsys ordering patterns to the
    federal Drug Enforcement Administration (DEA), Kapoor sought to
    tamp down any suspicions so that Insys could continue its modus
    operandi while concealing it from outside scrutiny.               Wholesalers
    serve   as    middlemen     between    pharmaceutical   manufacturers      and
    pharmacies and they impose quantity limits on the amount of
    controlled substances that a pharmacy can receive each month. When
    wholesalers      notice     suspicious     ordering   patterns,    they    are
    - 34 -
    obligated to notify the DEA.                 During the relevant time frame,
    several      pharmacies    that   served      Insys   speakers      overshot   their
    monthly quantity limits.              As a result, drug wholesalers froze
    Subsys shipments to those pharmacies.
    Insys executives knew that the reason for the freeze was
    that wholesalers' software algorithms to monitor order patterns
    had flagged Subsys orders as "potentially suspicious." In an email
    to Kapoor, Christopher Homrich, an Insys executive, told him that
    it was "very likely" that the DEA software would flag future orders
    from    those   pharmacies      as    "suspicious"      due    to   the   "material"
    increase in projected Subsys sales. Such freezes would be inimical
    to Insys's strategic aim of getting doctors to prescribe Subsys in
    heavy doses and without regard to medical necessity.                         Because
    "Kapoor      wanted   to   keep      doing   business"    with      the   physicians
    (particularly the whales) associated with the targeted pharmacies,
    he demanded that Insys executives "find an alternative to make
    sure one of our top customers has the product."
    To accomplish this end run around the DEA and to avoid
    the imminent freezes, Kapoor decided to explore a direct-ship
    option.      Such an option would have Insys ship Subsys straight to
    the pharmacy associated with the prescribing doctor.                         Insys's
    distribution manager (Dion Reimer) advised against this setup "at
    least    a   dozen    times."        Given    that    Subsys   was    a   controlled
    substance, "[t]rying to circumvent any of the systems that are out
    - 35 -
    there could raise red flags." Kapoor disregarded Reimer's protests
    and    authorized     sales     representatives           to    negotiate    supply
    commitments and direct-ship agreements with individual doctors.
    At his direction, Insys proceeded down this crooked path.5
    Kapoor insists that the direct-ship agreements were made
    only to "maximize sales of Subsys" and that he was "not trying to
    evade DEA rules."          But something that prowls like a tiger and
    growls like a tiger usually is a tiger — and Reimer's assessment
    of    the    direct-ship    option    as     a    means   of   circumventing     DEA
    guidelines seems spot-on.
    In arguing to the contrary, Kapoor points to Babich's
    testimony recounting how Insys retained "outside attorneys who
    have expertise with the DEA rules" to ensure the direct-ship
    arrangements were done "the right way."                   Babich also testified,
    though, that Insys "did not tell the lawyers who drafted the
    agreement[s]      that     [Insys     was]       providing     kickbacks    to   the
    physicians"      associated    with    these       pharmacies.      According     to
    Babich, that omission was deliberate:               the company feared that the
    bribes      contravened    federal    anti-kickback        law.    Under    certain
    circumstances, a party's retention of counsel may (as Kapoor
    Unscrupulous practitioners apparently welcomed the direct-
    5
    ship option. In one of the weekly sales representative reports,
    Kapoor was informed that Dr. Ahmad had committed to write "more
    scripts than [Insys] can handle . . . once the pharmacy issue is
    resolved." Other practitioners, including Drs. Couch, Ruan, and
    Awerbuch, also benefited from direct-ship agreements.
    - 36 -
    suggests) ground an inference of benevolent motive.                     See United
    States v. Powers, 
    702 F.3d 1
    , 9 (1st Cir. 2012).                But viewing what
    happened here in context, a jury instead could reasonably infer
    that direct-ship agreements were evidence of Kapoor's efforts to
    have doctors continue to prescribe Subsys illegitimately.                    See 
    id.
    (explaining that advice-of-counsel defense "is not available to
    one   who   omits   to    disclose    material      information    to    advisors"
    (quoting Janeiro v. Urological Surgery Prof. Ass'n, 
    457 F.3d 130
    ,
    140 (1st Cir. 2006))).
    Taking the evidence in the light most favorable to the
    verdict, a jury reasonably could conclude — as this jury did —
    that Kapoor relentlessly pursued pill mill doctors, pressured
    health-care    practitioners         to   increase    dosages     regardless      of
    medical     need     (through      financial        incentives     and       upfront
    prescription       commitments),      knew     of    and   encouraged        certain
    physicians'    illegitimate        prescribing       habits,     and     —    facing
    regulatory scrutiny for the burgeoning sales generated through
    these tactics — tried to hide the true state of affairs by cutting
    out the middleman.         Cf. Volkman, 797 F.3d at 391 (holding that
    evidence that defendants "were aware of the reality that the
    prescriptions from their clinic had no legitimate medical purpose"
    and that "[i]nstead of rectifying the . . . issues with [the]
    prescriptions,           [defendants]        exacerbated          the        problem
    by . . . cutting out the middleman" sufficed "for a jury to find
    - 37 -
    that   [defendants]     executed     a    plan      to   unlawfully   distribute
    controlled   substances      with    no    legitimate       medical   purpose").
    Consequently, we are satisfied that the adverse finding against
    Kapoor as to the CSA predicates was supported by the record and,
    therefore, should have been allowed to stand.
    This holding also dictates that we reinstate the jury's
    verdict   against   Kapoor    as    to    the    honest-services      predicates.
    Federal law prohibits a "scheme or artifice to defraud," 
    18 U.S.C. §§ 1341
    , 1343, including "a scheme or artifice to deprive another
    of the intangible right of honest services," 
    id.
     § 1346.                 A person
    contravenes this provision if, "in violation of a fiduciary duty,
    [he] participate[s] in bribery or kickback schemes."                  Skilling v.
    United States, 
    561 U.S. 358
    , 407 (2010).                   Kapoor disputes the
    "fiduciary duty" element and contends that the government failed
    to prove that he specifically intended health-care professionals
    to write medically illegitimate Subsys prescriptions.
    As the district court noted, the "overlap" between the
    CSA and honest-services predicates is striking.                  Gurry, 427 F.
    Supp. 3d at 187-88.       Just as the jury instructions for the CSA
    predicates   required    proof      beyond      a   reasonable   doubt    that   a
    particular defendant agreed that a health-care practitioner would
    prescribe Subsys outside the usual course of medical practice, the
    honest-services predicates required evidence that "the Defendant
    agreed and specifically intended that health-care practitioners
    - 38 -
    would breach their fiduciary duty to their patients by prescribing
    Subsys or a particular dose of Subsys outside the usual course of
    professional    practice    and   not    for   a    legitimate   purpose."
    Accordingly, the evidence supporting the intent element of the CSA
    predicates was "coextensive" with the evidence supporting the
    fiduciary duty element of the honest-services predicates.           Id. at
    188.
    That is game, set, and match.            Because we already have
    concluded that the evidence supports the jury's finding with
    respect to Kapoor's guilt regarding the CSA predicates, we must
    perforce conclude that the evidence supports the findings with
    respect   to    Kapoor's     guilt   regarding       the   honest-services
    predicates.    It follows that we must reverse the district court's
    partial grant of the Rule 29(c) motion in favor of Kapoor and
    reinstate the jury's findings as to him insofar as they pertain to
    both the CSA and honest-services predicates.
    B
    The district court set aside the jury's finding that Lee
    was guilty of conspiracy to commit racketeering activities through
    a pattern of racketeering acts that included the CSA and honest-
    services predicates.       The jury heard evidence, though, that Lee
    supervised the sales representative who reported that Dr. Madison
    had a "shady setup" and that patients at Dr. Madison's office "were
    just seeking medication."      When the sales representative spoke to
    - 39 -
    Lee   about     her    concerns    with    Dr.     Madison's    potential      law-
    enforcement issues, Lee replied that "[i]t was okay." Like Kapoor,
    she appeared unfazed by Dr. Madison's potential criminal liability
    and   "ensured        that   Dr.   Madison       understood    that     he     would
    speak . . . as much as [Insys] can utilize him" — which meant, of
    course, that Dr. Madison would continue to receive kickbacks.                    The
    only condition was that "he would prescribe a significant amount
    of Subsys, more and more as time went on, and increas[e] the dose."
    This condition had nothing to do with medical necessity.
    Lee's hot pursuit of Dr. Madison supports the conclusion
    that getting doctors to write illegitimate prescriptions was not
    merely an unforeseeable risk of her work for Insys but, rather, an
    integral part of the business model that she assiduously followed
    while doing that work.        As Babich explained, Dr. Madison was made
    a   speaker    notwithstanding      that     his   clinic     was   a   pill    mill
    "[b]ecause he was the biggest writer of the type of product in the
    Chicago land area, and getting that revenue was very important to
    [Insys] as a company."         A jury could reasonably infer that Insys
    knowingly counted on revenue from illegitimate prescriptions and
    that Lee (as a regional sales manager who benefitted handsomely
    from greater sales) intended to keep that revenue stream flowing
    even if it meant prescribing Subsys to patients who did not
    legitimately need it.
    - 40 -
    Other evidence corroborated     the conclusion that Lee
    intended prescribing doctors to expand the company's customer base
    to people who did not qualify medically to use Subsys.          The
    regional managers were instructed by Simon "to get a specific
    number of scripts per week that is mutually agreed to and an
    outline of how [the representatives who reported to them] will
    hold [them]selves and [their] customers to this plan."     In other
    words, salespeople were to negotiate prescription quotas with the
    doctors in their territories.       These quotas   had no apparent
    relationship to either medical necessity or patient needs, and the
    jury had an ample basis for inferring that Lee followed Simon's
    instructions.
    Here, too, Lee's experience with Dr. Madison exemplifies
    the point.   As a speaker, Dr. Madison was expected to maintain or
    exceed previous prescription-writing numbers.      When Dr. Madison
    fell short, Lee would order a sales representative "to continue to
    put pressure on [Dr. Madison]" and tell the doctor "that if he's
    going to keep doing these programs, he needs to keep his writing
    up."   There was no medically informed rationale for Dr. Madison's
    quota, and his agreement to abide by such a quota is a surefire
    sign that Lee knew that, under that agreement, Dr. Madison would
    be prescribing Subsys illegitimately. Cf. United States v. Hughes,
    
    895 F.2d 1135
    , 1142 (6th Cir. 1990) (reaching similar conclusion
    regarding quota for blood tests).      Her incessant enforcement of
    - 41 -
    the quota therefore is evidence that she intended for Dr. Madison
    to write those illegitimate prescriptions.      The way that Lee did
    business with Dr. Madison is emblematic of her intent to have
    health-care practitioners forsake medical necessity for financial
    gain.
    We conclude that the adverse finding against Lee as to
    the CSA predicates was supported by the record and, therefore,
    should have been allowed to stand.      And as with Kapoor, see supra
    Part III(A), this holding dictates that we reinstate the jury's
    findings as to the honest-services predicates.     It follows that we
    must reverse the district court's partial grant of the Rule 29(c)
    motion in favor of Lee as it pertains to both the CSA and honest-
    services predicates.
    C
    The district court set aside the jury's finding that
    Simon was guilty of conspiracy to commit racketeering activities
    through a pattern of racketeering acts that included the CSA and
    honest-services predicates.    Once again, we disagree.       On this
    record, a    reasonable jury could conclude that      Simon   (also a
    regional manager)    intended health-care providers     to prescribe
    Subsys outside the usual course of professional practice.
    Simon encouraged the sales force to agree with each
    practitioner on a "specific number of scripts per week" — a quota
    — and to "push the dose."   Relatedly, sales representatives under
    - 42 -
    his   supervision   pressured   health-care   practitioners   to   write
    medically illegitimate prescriptions.       For example, nurse Heather
    Alfonso agreed with her sales representative "to do one to two
    scripts per week."     She later admitted that she "had come to rely
    on th[e] extra money" and had "broke[n her] duty to patients."
    So, too, Dr. Awerbuch was informed, at Simon's behest, that "the
    average of his prescriptions was very low, within the one to 200
    microgram range."    As he recalled it, he then "started prescribing
    [Subsys] to patients who didn't really even need to be on it just
    to increase [his] numbers."
    A reasonable jury could infer from the evidence that
    illegitimate prescriptions were not an unintended consequence of
    Simon's sales techniques but, rather, were a goal.       With an eye on
    revenue, Simon specifically sought to have practitioners prescribe
    Subsys to patients who did not need it. It was Simon, for instance,
    who endeavored to enforce a minimum-dosage agreement with Dr.
    Somerville.    As a result, Dr. Somerville entered into a Faustian
    bargain with Insys that required, in Simon's own words, "every
    refill" to be for at least 180 micrograms.         In facilitating this
    arrangement,   Simon    not   only   knew   that   prescriptions   would
    thereafter be untethered from patients' medical histories but also
    solicited precisely that outcome. As one defense expert explained,
    a doctor "decide[s]" whether the medication is warranted "at the
    moment while [she's] seeing the patient," not "a week in advance."
    - 43 -
    Accordingly, a reasonable jury could find that Simon intended
    doctors to prescribe Subsys outside the course of professional
    practice because his quota arrangements required them to commit
    both to specific numbers of Subsys prescriptions and to specific
    dosages before they had a chance either to examine their patients
    or to assess patients' medical needs.                See Hughes, 
    895 F.2d at 1142
    ; United States v. Mahar, 
    801 F.2d 1477
    , 1487 (6th Cir. 1986)
    ("[T]hat    patients      were   regularly     sold    controlled   substances
    . . . selected by non-physician[s] . . . would further support a
    finding that controlled substances were issued outside the usual
    course     of   medical    practice    and     for    no   legitimate   medical
    purpose.").
    We conclude that the adverse finding against Simon as to
    the CSA predicates was supported by the record and, therefore,
    should have been allowed to stand.             And as with Kapoor, see supra
    Part III(A), this holding dictates that we reinstate the jury's
    findings as to the honest-services predicates.              It follows that we
    must reverse the district court's partial grant of the Rule 29(c)
    motion in favor of Simon as it pertains to both the CSA and honest-
    services predicates.
    D
    As with Kapoor, Lee, and Simon, the district court set
    aside the jury's finding that Rowan was guilty of conspiracy to
    commit racketeering activities through a pattern of racketeering
    - 44 -
    acts that included the CSA and honest-services predicates.            Here,
    too, the evidence supports a finding that Rowan intended doctors
    to write medically illegitimate prescriptions.          Rowan worked hard
    to develop quota agreements.      For example, he was not shy about
    communicating    his   prescription    expectations      to   Dr.   Couch.
    According to one witness, Rowan gave Dr. Couch "a hard time about
    the fact he hadn't been prescribing enough" and threatened to
    "take[] away" the speaking programs (and, thus, the kickback
    payments) if Dr. Couch "wasn't prescribing enough."                 Rowan's
    aggressive enforcement of prescription quotas is evidence that he
    knew that he was soliciting prescriptions that were not medically
    necessary.   See Hughes, 
    895 F.2d at 1135
    .        Given that knowledge,
    the kickbacks that Rowan was arranging constituted incentives for
    prescribers to prescribe Subsys illicitly.        See 
    id.
    The jury also heard evidence that Rowan had reason to
    believe   that   successful   performance   of    his   job   depended   on
    promoting illicit prescription-writing.          His dealings with Dr.
    Ruan illustrate this point.    Rowan spoke directly with Dr. Ruan to
    make clear that Insys would "pay [Dr. Ruan] as much as we possibly
    and humanly can in exchange to write as much Subsys as [Dr. Ruan]
    humanly can." In the same vein, the government introduced evidence
    that Rowan understood that Dr. Ruan would find a way to prescribe
    more as long as the dollars kept flowing.        The facts on the ground
    confirmed Rowan's understanding:      Dr. Ruan ultimately wrote enough
    - 45 -
    Subsys prescriptions to boost Rowan into a position as Insys's top
    sales representative anywhere in the country.                  Moreover, Rowan's
    soaring sales figures exemplified the success of the kickback
    scheme, and he was repeatedly mentioned in the 8:30 a.m. management
    calls as a poster child for the proposition that "if you give these
    [doctors] programs, they're going to write the drug for you."
    There was more.          After the DEA froze opioid shipments to
    the pharmacy that principally filled Dr. Ruan's prescriptions,
    Rowan learned that the pharmacy had access to an "unlimited supply"
    of a competing opioid.          He learned as well that the pharmacy wanted
    not only a similar arrangement for Subsys in order to circumvent
    "limits   on    [Schedule       II    drugs]    in    place   by   [the]   current
    wholesaler" but also "to ensure uninterrupted delivery to patients
    of Dr. [Ruan]."           Although by then Rowan either knew or was
    willfully      ignorant    of    Dr.    Ruan's       pill   mill   tendencies,   he
    nonetheless became involved in negotiating a direct-ship agreement
    for Dr. Ruan.       He (along with Kapoor and Babich) attended the
    dinner meeting with Dr. Ruan at which the direct-ship agreement
    was finalized.
    Taking this proof in the light most favorable to the
    verdict, a reasonable jury could conclude that Rowan intended Drs.
    Couch and Ruan to prescribe Subsys outside the accepted course of
    medical practice.         See Volkman, 797 F.3d at 391.               Because the
    record supports a determination that Rowan agreed to commit CSA
    - 46 -
    violations, the jury's finding to that effect should not have been
    vacated.    See Kilmartin, 944 F.3d at 325.             And as with Kapoor, see
    supra Part III(A), this holding dictates that we reinstate the
    jury's findings as to the honest-services predicates.                     It follows
    that we must reverse the district court's partial grant of the
    Rule 29(c) motion in favor of Rowan as it pertains to both the CSA
    and honest-services predicates.
    E
    We add a coda.         As said, the district court rested its
    vacation    of     certain    predicates       on    the     so-called    equipoise
    principle, holding that because the proof "gives equal or nearly
    equal circumstantial support to a theory of guilt and a theory of
    innocence," Gurry, 427 F. Supp. 3d at 186 (quoting Burgos, 703
    F.3d at 10), those predicate-act findings should be set aside.                    We
    conclude    that    the     equipoise   principle       was    inapposite:       the
    evidence,   viewed     in    the   requisite        light,    was   not   so   evenly
    balanced.    We summarize our reasoning.
    We start with common ground:             we agree with the district
    court that the equipoise principle is entrenched in this circuit's
    jurisprudence.       When "the 'evidence viewed in the light most
    favorable to the verdict gives equal or nearly equal circumstantial
    support to a theory of guilt and a theory of innocence of the crime
    charged,' this court must reverse the conviction."                   United States
    v. Flores-Rivera, 
    56 F.3d 319
    , 323 (1st Cir. 1995) (quoting United
    - 47 -
    States v. Sanchez, 
    961 F.2d 1169
    , 1173 (5th Cir. 1992)).       But "this
    equal-evidence rule takes hold only after [the inquiring court]
    ha[s] drawn all reasonable inferences in favor of the verdict."
    Magraw v. Roden, 
    743 F.3d 1
    , 5 (1st Cir. 2014) (emphasis in
    original).    Here — as we already have explained — the evidence,
    viewed in the light most favorable to the jury verdicts, clearly
    favors a finding that the defendants conspired to distribute Subsys
    even when the drug served no legitimate medical purpose. See supra
    Parts III(A)-(D).     "When the[se] pieces of evidence are layered,
    with inferences taken in the government's favor, this is not a
    case in equipoise."    United States v. Ortiz, 
    447 F.3d 28
    , 34 (1st
    Cir. 2006).    Rather, it is a case in which a jury could find,
    beyond a reasonable doubt, that the four affected defendants
    (Kapoor,   Lee,   Simon,   and   Rowan)   conspired   with   health-care
    practitioners to write Subsys prescriptions outside the course of
    accepted medical practice and without any medical justification.
    We conclude, therefore, that the equipoise principle simply did
    not apply.    To the contrary, this is a case in which the jury
    supportably found that the government had proved the CSA and
    honest-services predicates beyond a reasonable doubt.        It follows,
    then, that the district court erred in vacating those findings.
    IV
    The jury found all five defendants guilty with respect
    to the mail- and wire-fraud predicates.      In their joint Rule 29(c)
    - 48 -
    motion, four of the defendants (Kapoor, Lee, Simon, and Rowan)
    challenge     the    sufficiency      of   the   evidence    underlying    these
    findings.6        As the district court saw it, however, the evidence
    supported those portions of the jury's findings and, thus, left
    them intact.        The four named defendants appeal that ruling.
    The mail-fraud statute prohibits use of the mails in
    connection with a "scheme or artifice to defraud."                    
    18 U.S.C. § 1341
    .      To     establish   the    commission    of     this   offense,   the
    government must show a scheme to defraud using false pretenses,
    the defendant's knowing and willing participation in the scheme
    with the intent to defraud, and the use of the mails in furtherance
    of that scheme.        See United States v. Soto, 
    799 F.3d 68
    , 92 (1st
    Cir. 2015).
    The mail- and wire-fraud offenses share common elements.
    They differ only in that, to prove a violation of the wire-fraud
    statute, the government must establish the use of wires (rather
    than the use of the mails) in furtherance of the alleged scheme.
    See United States v. Arif, 
    897 F.3d 1
    , 9 (1st Cir. 2018).
    A
    We     start   with      Kapoor's     claims     of    evidentiary
    insufficiency with respect to the mail-fraud predicate.                   We can
    make short shrift of them.
    6 Gurry separately challenges these findings in his motion
    for a new trial. See infra Part XII.
    - 49 -
    1
    Kapoor       disputes    the   sufficiency         of    the    evidence   in
    connection with the mail-fraud predicate only with respect to the
    third element:       whether the use of the mails furthered the alleged
    scheme.      To   this   end,   he   argues      that    the      mailed    bribes   to
    practitioners did not further the misrepresentations to insurers
    regarding patients' conditions.              We do not agree.
    The "in furtherance" requirement is to be read broadly.
    United States v. Hebshie, 
    549 F.3d 30
    , 36 (1st Cir. 2008).                     "[T]he
    use of the mails need not be an essential element of the scheme."
    Schmuck v. United States, 
    489 U.S. 705
    , 710 (1989).                      To prove this
    element, the government need only show that the mailing was
    "incident to an essential part of the scheme," 
    id. at 711
     (quoting
    Pereira v. United States, 
    347 U.S. 1
    , 8 (1954)), or "a step in
    [the] plot," 
    id.
     (quoting Badders v. United States, 
    240 U.S. 391
    ,
    394 (1916)).      We therefore parse the record to determine whether
    the evidence shows some "connection or relationship" between the
    mailing and the fraudulent scheme.                 Hebshie, 
    549 F.3d at 36
    (quoting United States v. Pimental, 
    380 F.3d 575
    , 587 n.5 (1st
    Cir. 2004)).
    We find that the record shows a sufficient connection.
    The mailed bribes generated prescriptions, which were fraudulently
    processed through the IRC's authorization scheme.                   And in order to
    facilitate     the    fraudulent     processing         of     prior-authorization
    - 50 -
    requests, Insys offered business liaisons to whales (prolific
    prescribers) who received bribes through the mail.            Such bribe
    recipients included Drs. Awerbuch, Chun, and Ahmad.
    "The relevant question at all times is whether the
    mailing is part of the execution of the scheme."             Schmuck, 
    489 U.S. at 715
    .     Because the scheme alleged here involved mailing
    bribes for writing medically illegitimate Subsys prescriptions and
    then obtaining insurance payments for those prescriptions, we
    conclude that a jury reasonably could answer this question in the
    affirmative.
    Kapoor resists this conclusion.      He argues that because
    the   IRC   processed   all   the     prescriptions   that   it   received
    (regardless of whether the prescribing doctor was bribed), the
    scheme to defraud insurers did not "depend" on the bribes mailed
    to doctors.    In support, Kapoor notes that the bribed doctors were
    only a "small fraction" of the doctors whose prescriptions were
    fraudulently processed through the IRC.
    This argument misses the mark:      the government need not
    show that the fraudulent scheme would have petered out without the
    bribes.     The mail-fraud statute does "not require[] a 'but-for'
    link between a mailing and the fraudulent scheme."           Hebshie, 
    549 F.3d at 36
     (quoting Pimental, 
    380 F.3d at 587
    ).         It requires only
    a connection between the two, and the record, read in the light
    most favorable to the government, supports an inference that the
    - 51 -
    bribes, in increasing the volume of prescriptions, facilitated the
    scheme.     No more is exigible to uphold the jury's mail-fraud
    finding.
    2
    As a fallback, Kapoor essays a constructive amendment
    claim.    In mounting this claim, he says that the mail-fraud scheme
    described by the district court differed from that charged in the
    indictment.    The government, he adds, failed to adduce sufficient
    proof of the latter scheme.
    Specifically, he calls our attention to paragraph 31 of
    the indictment, in which the grand jury alleged that "[h]ad the
    insurers known that the defendants gave bribes and kickbacks to
    the targeted practitioners, the insurers would not have authorized
    payment for Subsys."        Because the government did not show that
    Kapoor    "intended   for   the   IRC       to   affirmatively   misrepresent"
    Insys's bribes to practitioners, his thesis runs, it failed to
    substantiate the scheme it alleged.               Although Kapoor gets high
    marks for ingenuity, his claim fails the constructive-amendment
    test.
    "A constructive amendment            'occurs when the charging
    terms of the indictment are altered, either literally or in effect,
    by prosecution or court after the grand jury has last passed upon
    them.'" United States v. Dunn, 
    758 F.2d 30
    , 35 (1st Cir. 1985)
    (quoting Gaither v. United States, 
    413 F.2d 1061
    , 1071-72 (D.C.
    - 52 -
    Cir. 1969)).      "[O]ur practice has been to look to statutory
    elements in response to claims by defendants that 'the crime
    charged' has been changed."      United States v. Mubayyid, 
    658 F.3d 35
    , 51 (1st Cir. 2011).      Therefore, "[s]o long as the statutory
    violation remains the same, the jury can convict even if the facts
    found are somewhat different than those charged."       
    Id.
     (quoting
    United States v. Twitty, 
    72 F.3d 228
    , 231 (1st Cir. 1995)); see
    United States v. Dowdell, 
    595 F.3d 50
    , 68 (1st Cir. 2010).
    In this case, the putative amendment occurred after
    trial (when the court denied the defendants' joint Rule 29(c)
    motion).   Thus, Kapoor had no realistic opportunity to assert his
    constructive amendment claim below.       Consequently, this claim of
    error engenders de novo review.      See United States v. Rodriguez,
    
    919 F.3d 629
    , 635 (1st Cir. 2019); United States v. Hernández, 
    490 F.3d 81
    , 83 (1st Cir. 2007).
    We discern nothing resembling a constructive amendment
    here.   The crime charged was not altered because the language in
    paragraph 31 did not implicate the statutory elements of the RICO
    conspiracy.     To prove a RICO conspiracy, "it is enough to prove
    that a defendant agreed with one or more others that two predicate
    offenses be committed."     Aetna Cas. Sur. Co. v. P & B Autobody, 
    43 F.3d 1546
    , 1562 (1st Cir. 1994) (emphasis in original).           The
    predicate offenses themselves, however, are not elements required
    to be proved.    See 
    id.
       Since Kapoor was not "convicted of a crime
    - 53 -
    other    than    that    charged   in    the   indictment,"    no   constructive
    amendment occurred.7        United States v. Day, 
    700 F.3d 713
    , 720 (4th
    Cir. 2012) (quoting United States v. Randall, 
    171 F.3d 195
    , 203
    (4th Cir. 1999)).
    "[T]he rule against constructive amendments . . . is
    focused not on particular theories of liability but on the offenses
    charged in an indictment."              Id. at 720 (emphasis in original).
    Although    the    district    court's     order   "eliminated      a   theory    of
    liability" alleged in paragraph 31, United States v. Celestin, 
    612 F.3d 14
    , 25 (1st Cir. 2010), "the statutory violation remain[ed]
    the same," Mubayyid, 
    658 F.3d at 51
     (quoting Twitty, 
    72 F.3d at 231
    ).      For    that   reason,   the    district   court's    order     did    not
    constructively amend the indictment in any forbidden way.                        See
    Celestin, 
    612 F.3d at 25
    ; United States v. Miller, 
    471 U.S. 130
    ,
    145 (1985); cf. United States v. Mueffelman,

    Cir. 2006) (distinguishing forbidden constructive amendment from
    7 For the sake of completeness, we note that the challenged
    language tracked one of the government's earlier theories of fraud
    liability. The government originally alleged that each time Insys
    submitted a Subsys authorization request on behalf of a bribed
    doctor, the defendants committed fraud just by omitting
    information about the bribe.     The district court rejected this
    theory, ruling from the bench that not "every prescription is bogus
    just because there was a kickback behind it." Hence, the court
    said, there was "[no] obligation to disclose [the kickback]." From
    that point forward, the government elected to pursue only the
    remaining mail-fraud allegations in the indictment.

    one alleging "a scheme similar to but somewhat narrower in breadth
    and malignity than that charged in the indictment").
    B
    Lee's    challenge    to    the     sufficiency    of    the     evidence
    underlying the mail- and wire-fraud predicates need not detain us.
    We previously have limned the elements of those offenses.                        Lee
    disputes only the second element of each offense — her knowing and
    willing participation in the scheme with the intent to defraud —
    and claims that the government failed to show that she had the
    requisite knowledge of, or involvement in, the scheme.                The record
    belies her protestations.
    Wire     transmission       of      authorization       requests       and
    approvals was essential to the operation of the IRC, and the
    government's proof showed that Lee had both extensive interactions
    with the IRC and a working knowledge of the approval process.                     A
    few examples will suffice to hammer home the point:
    •     During the IRC's pilot phase, Gurrieri communicated
    directly     with        Lee    about      Dr.      Awerbuch's
    prescriptions.       Lee received a list of over one
    hundred prescriptions that the IRC was attempting
    to process on Dr. Awerbuch's behalf.
    •     Lee supervised the representative assigned to Dr.
    Awerbuch,    who    helped     process    the    authorization
    requests;    she    also    arranged     the    hiring    of   Dr.
    - 55 -
    Awerbuch's niece as a business liaison to "fill out
    the forms," "get the prescriptions pushed through,"
    and "work[] with th[e] IRC."
    •   Lee    was    "very    close"   to   an   IRC   authorization
    specialist and lobbied for her promotion.
    •   Lee tried very hard to maximize the authorization
    rate because she understood that Insys got paid
    (and    her    own    compensation    increased)     only    if
    insurers approved the drug.
    We add, moreover, that the record supports an inference
    that Lee pushed for prior authorizations with knowledge that the
    information that the IRC relayed to insurers was inaccurate.                   She
    worked closely with Drs. Madison and Awerbuch, who were two of the
    most prolific prescribers of Subsys in the country.                  The record
    likewise supports an inference that Lee knew that these prescribers
    were writing medically illegitimate prescriptions.                 Because these
    prescriptions would not get insurance approval organically, sales
    representatives had to be "coach[ed]" on the misleading diagnosis
    codes to be provided to insurers, and Lee was aware of this
    coaching because she was copied in emails that discussed it.
    On this record, a jury unquestionably could conclude
    that Lee knew that the IRC was processing medically illegitimate
    prescriptions      by     deliberately      providing    insurers     misleading
    information.       The jury also could conclude that Lee agreed to
    - 56 -
    facilitate the fraudulent scheme by generating more prescriptions
    for the IRC to process through mailed bribes and by streamlining
    Dr.   Madison's         and     Dr.    Awerbuch's     insurance-authorization
    processes.     The district court, therefore, did not err in denying
    Lee's motion for judgment of acquittal on the mail- and wire-fraud
    predicates.
    C
    Simon's evidentiary insufficiency claim with respect to
    the mail- and wire-fraud predicates is easily dispatched.                         Like
    Lee, Simon disclaims knowledge of or involvement in the insurance-
    fraud scheme.       See Soto, 799 F.3d at 92; Arif, 897 F.3d at 9.                 The
    record, however, tells a different tale:                  it supports the jury's
    findings as to both predicates.
    The evidence shows that Simon understood, assisted, and
    furthered     the       IRC's     fraudulent      activities.         The     sales
    representatives who reported to him informed him whenever a doctor
    granted     the   IRC    permission      to     contact    an   insurer     for     an
    authorization, and he was copied on emails reporting denials by
    insurers.     To convey this information to senior management, Simon
    created "charts in progress" reports which documented the IRC's
    efforts to obtain authorization for each Subsys prescription.                       In
    addition, it was Simon who created the business liaison program.
    A   jury   reasonably         could   envision    these     efforts   as    knowing
    facilitation of the IRC's corrupt authorization processes.
    - 57 -
    The record also supports an inference that Simon sought
    to maximize the IRC's success despite knowing that the information
    the authorization specialists supplied to insurers was misleading
    and/or false.    He was an occasional participant in the 8:30 a.m.
    daily management calls, during which Kapoor and other senior
    executives    regularly   discussed   the   IRC   and   strategies   for
    obtaining insurer authorizations.        Such strategies included the
    use of misleading words, phrases, and diagnosis codes, as well as
    the "spiel."    What is more, the government introduced evidence
    that Simon saw these strategies in action when he visited the IRC
    and listened to calls during which employees contacted insurers
    and requested Subsys authorizations.        From this evidence, a jury
    reasonably could find that Simon had knowledge of the IRC's
    fraudulent activities, yet chose to feed the IRC more prescriptions
    by bribing doctors through the mail.      It follows that the district
    court did not err in denying Simon's motion for judgment of
    acquittal on the mail- and wire-fraud predicates.
    D
    Rowan's claim of error with respect to the sufficiency
    of the evidence underlying the mail- and wire-fraud predicates is
    bootless.    He, too, challenges only the intent element of the
    jury's adverse findings on the mail- and wire-fraud predicates.8
    8 The government asserts that Rowan failed to preserve this
    claim of error and that, therefore, review is only "for clear and
    - 58 -
    See Soto, 799 F.3d at 92; Arif, 897 F.3d at 9.                          Our review
    discloses, however, that the record is shot full of evidence that
    Rowan    monitored,     facilitated,       and       participated     in     the   IRC
    authorization process.          For instance, he personally arranged a
    liaison for Dr. Chun and he instructed his subordinate (a sales
    representative) to have the "[prior authorization] form filled out
    every day with update to [Gurry]" and "to do whatever we could to
    help and assist in getting that insurance pull-through."                      Various
    of his subordinates reported to Rowan to confirm that doctors had
    completed      IRC   opt-in    forms    and     to    alert    him    when    doctors
    encountered difficulty obtaining insurance approvals.                         A jury
    reasonably could conclude that these were deliberate efforts to
    support the corrupt IRC authorization procedure.
    To cinch the matter, a jury reasonably could conclude
    that Rowan undertook these efforts notwithstanding his knowledge
    that the IRC was deliberately misleading insurers. Rowan had every
    reason    to    believe       that   Dr.   Ruan       was     prescribing      Subsys
    illegitimately, and a reasonable jury could infer that Rowan knew
    that the IRC's efforts to get prior authorization for many of Dr.
    Ruan's prescriptions were likewise illegitimate.                     His attendance
    at an IRC training session corroborates such an inference.                         At
    gross injustice."   United States v. Foley, 
    783 F.3d 7
    , 12 (1st
    Cir. 2015).    We assume, without deciding, that the claim was
    preserved and, therefore, engenders de novo review. See Kilmartin,
    944 F.3d at 325.

    that session, Rowan heard about the IRC's "history of cancer"
    practice, including an explicit instruction to the authorization
    specialists to include a reference to cancer even if "that's not
    what we're seeing them for" because such a reference meant a "sure
    approval" from insurers.       So, too, Rowan learned that the IRC
    maintained a list of drugs for authorization specialists to include
    as tried-and-failed medications — a list that was to be used
    liberally   even   if   particular   patients   had   not   furnished   any
    information about prior medications.       It thus seems nose-on-the-
    face plain that, after this session, Rowan knew that the IRC was
    defrauding insurers both because it cited bogus medical rationales
    in support of prescriptions and because it provided apocryphal
    lists of tried-and-failed medications.       Yet, he continued to work
    hand-in-glove with the IRC.
    We do not gainsay that the jury was free to conclude, as
    Rowan argues, that the IRC training session was innocuous.              But
    there were two sides to this particular story, and "it [was] within
    the   jury's    purview   to   evaluate   [these]     competing   factual
    inferences."    United States v. Ridolfi, 
    768 F.3d 57
    , 61 (1st Cir.
    2014).   Rowan's efforts to bribe doctors through the mail and to
    push through Dr. Ruan's prescriptions despite Rowan's knowledge of
    what was going on supports the conclusion that he knowingly and
    willingly participated in the scheme with the intent to defraud
    insurers.      It follows that the district court did not err in
    - 60 -
    denying Rowan's motion for judgment of acquittal on the mail- and
    wire-fraud predicates.
    V
    The district court admitted at trial testimony of nine
    patients who had received Subsys prescriptions from doctors who
    participated in the kickback scheme.                   All    of the       defendants
    challenge the admission of their testimony as irrelevant and unduly
    prejudicial.     Some stage-setting is needed.
    The    defendants         had       anticipated       the    government's
    presentation of evidence that patients had suffered harm from
    taking Subsys.        Prior to the trial, they moved to exclude such
    evidence in its totality.          The district court granted their motion
    in part, leaving the government free to present testimony about
    "the   medical   care    that      patients     received     from      co-conspirator
    physicians" and their "medical status."              This evidence was allowed
    for the purpose of showing "that prescribing was not medically
    necessary or was in excess of what was medically necessary, or
    that a patient's medical status was different from what was
    represented      to     insurers      in       furtherance       of      claims    for
    reimbursement."         The   court    also     allowed    the    introduction      of
    evidence showing "that a patient became addicted to Subsys, the
    medical   consequences        of   that    addiction,      and    whether    and   how
    prescribing practices changed thereafter."                 Striving to strike a
    balance, though, the court prohibited "evidence concerning the
    - 61 -
    social consequences to the patient of wrongful prescribing or
    addiction,    such    as    loss    of    employment,          erosion    of    familial
    relationships, and the like."
    At the final pretrial conference, the defendants renewed
    their objections to patient-harm evidence.                 The government argued
    that it should be allowed to elicit testimony as to patients'
    medical histories (e.g., whether a patient had cancer) "because
    the IRC, which is run by Insys, is telling the pharmacy benefit
    managers and other insurers that patients have cancer when the
    patient doesn't have cancer." This testimony, the government said,
    was    intended   "primarily       to    prove    the    fraud."         So,    too,    the
    government wanted to adduce testimony about the effects that Subsys
    had on patients — that they "couldn't function[,] [t]hey slept all
    day[,] [t]hey became addicted."
    The district court essentially reaffirmed its earlier
    ruling.    The court noted that the charged conspiracy involved "not
    just      defrauding        the         insurance        company,"            but      also
    "overprescri[ption]         and    increase       [in]     prescriptions."               It
    therefore concluded that the government should be "allowed to put
    that evidence on to show that [the defendants] succeeded in their
    objective,    which    is   evidence       of    the    fact    that     it    was   their
    objective."
    During trial, the defendants objected for a third time
    to evidence of patient harm.               In response, the district court
    - 62 -
    reiterated that it would not broadly preclude such testimony. When
    the defendants renewed their objections yet again, the court
    reiterated that testimony regarding addiction was "fair game."
    All    in   all,     nine     patients   testified   about   the
    debilitating effects of addiction that they experienced while
    ingesting Subsys.     We offer a representative sampling of this
    testimony:
    •   Cathy Avers testified that, as a result of taking
    Subsys, she "bec[a]me an addict" such that "[n]o
    matter how much [she] took, eventually it just
    wasn't enough."       She testified to side effects such
    as "having a hard time functioning, standing up,
    going to sleep.        It was such an impact on [her]
    being able to get up, out of bed, get dressed, and
    do anything."        She confirmed that the information
    Insys had provided to her insurer — that she had a
    current cancer diagnosis, was taking morphine and
    hydromorphone, and was using a fentanyl patch — was
    apocryphal.
    •   Paul Lara testified that, while taking Subsys, he
    wound up "not finding [his] way home in a town
    [he'd] lived in all [his] life" and having "to call
    [his] wife to get directions home."       He repeatedly
    hallucinated and "thought [he] was going crazy."
    - 63 -
    He could not follow what customers were saying to
    him at work and once "literally three or four" of
    his teeth "[fell] out right there [while] talking
    to a customer."       He also confirmed that Insys's
    representations      to   his   insurer   that   he    had   a
    current diagnosis of cancer were spurious.
    •   Sara Dawes testified that, while taking Subsys, she
    was "unable to function" and spent "most of [her]
    time in bed."     When she stopped taking Subsys, she
    "was very, very, very sick and mentally couldn't
    hold it together" to the point that she had "a
    breakdown" and "drove off and left [her] kids on
    Christmas." She also testified that, contrary to
    what Insys had told her insurer, she never had
    cancer, never had taken methadone, and did not have
    difficulty ingesting generic fentanyl products.
    •   Betty Carrera testified that, while taking Subsys,
    she began having such phantasmagoric hallucinations
    that the police had to be called several times.
    She could not function and spent her days sleeping.
    She said that, when withdrawing from Subsys, she
    had nightmares and hallucinations, and she would
    "[wake]   up    at   night      screaming."      She    also
    - 64 -
    contradicted Insys's representations to her insurer
    and testified that she never had issues swallowing.
    •   Woodrow Chestang described "slobber . . . just
    run[ning] down [his] mouth," watching the clock,
    and craving more Subsys between doses.                   When he was
    unable    to    get     Subsys,     he     experienced         delirium
    tremens, nausea, and inability to eat or drink.                     He
    sometimes       curled     "into     a     fetal    position"      and
    realized that he was "burn[ing] up with fever."                     He
    added that, contrary to the information that Insys
    had given to his insurer, he neither had a history
    of    cancer    nor     had    previously         been     prescribed
    generic opioid containing fentanyl.
    •   Scott    Byrd     testified         that    Subsys       was    "life-
    changing" because "[i]t put [him] into an addiction
    state    that    [he]      almost    couldn't       come    out    of."
    Because he used more than the quantity that his
    doctor    had    prescribed,         he     ran    out     early   and
    experienced major withdrawal.                He also swore that
    the   signature       on      the   opt-in        form   purportedly
    authorizing Insys to contact his insurer on his
    behalf was not his and, in fact, misspelled his
    name.
    - 65 -
    •   Kendra Skalnican testified that she developed an
    addiction     after    starting    on    Subsys,       and,    as    a
    result, began to take more of the medication than
    had   been    prescribed.         When    she    ran    out,    she
    experienced severe withdrawal, sweating, vomiting,
    diarrhea, and pain all over her body.                 She told the
    jury that Subsys "made [her] addicted" and "[she]
    slept a lot of [her] life away." She also testified
    — contrary to information provided by Insys to her
    insurer — that she never had issue swallowing pills
    and never had tried other fentanyl products.
    •   Michelle     DiLisio    (previously       Kamzyuk)      testified
    that,   while    taking    Subsys,       she    was    lethargic,
    fatigued, dizzy, and felt "out of it." She reported
    that she suffered from severe withdrawal symptoms
    after she stopped taking the medication.                  And she
    made clear that the information that Insys had
    furnished to her insurer was false: she never had
    "any cancer ever" and, specifically, she never had
    ovarian cancer (indeed, she had undergone ovary-
    removal      surgery   years     before    Subsys       had    been
    prescribed for her).
    •   Alicia Hinesley testified that Subsys made her
    "extremely      sleepy"    and     led    to    difficulty          in
    - 66 -
    thinking.        Sometimes she would sit or sleep all
    day.      Belying     Insys's   statements      that       she   was
    experiencing breakthrough cancer pain, she flatly
    denied that she ever had cancer.
    After       the   jury    verdicts      had    been    returned,         the
    defendants moved for a new trial.            They argued that the admission
    of the patient-harm testimony constituted reversible error.                          The
    district court thought not:               it concluded that "[t]he patient
    testimony at trial conformed to the Court's motion in limine ruling
    in which it allowed only limited use of patient testimony and
    carved    out    most      inflammatory     aspects,       such   as     the    social
    consequences of addiction."            Gurry, 427 F. Supp. 3d at 203.                The
    testimony, the court said, "was relevant to show the medical care
    that     patients     received    from     co-conspirator         prescribers,        to
    demonstrate      that      certain     prescriptions       were    not     medically
    necessary or were excessive, and to support claims that a patient's
    medical    status     was     different    from     what    was    represented       to
    insurers."      Id.
    It hardly bears repeating that a trial court enjoys
    considerable discretion with respect to its evidentiary rulings.
    See United States v. Zaccaria, 
    240 F.3d 75
    , 78 (1st Cir. 2001).
    We review the rulings that the defendants challenge here only for
    abuse of that discretion.            See Iacobucci v. Boulter, 
    193 F.3d 14
    ,
    20 (1st Cir. 1999).
    - 67 -
    A
    We start with the defendants' claim that the challenged
    testimony was irrelevant.      The standard for relevancy is not
    exacting.    See United States v. Rivera Calderón, 
    578 F.3d 78
    , 97
    (1st Cir. 2009).   The patient-harm testimony is relevant if it has
    the "tendency to make the existence of any fact that is of
    consequence to the determination of the action more probable or
    less probable than it would be without the evidence." 
    Id.
     (quoting
    Fed. R. Evid. 401).
    The district court appropriately found that the patient-
    harm testimony was relevant.     To prove the CSA predicates, the
    government had to show that the defendants agreed that a health-
    care practitioner would prescribe Subsys outside the usual course
    of medical practice and without any legitimate medical purpose.
    See Volkman, 797 F.3d at 391.         The evidence of the patients'
    altered behavior, addiction, and withdrawal symptoms was plainly
    relevant to show that the doctors' treatment was outside the course
    of professional practice.     This is particularly true where, as
    here, each doctor continued to prescribe Subsys to his or her
    patient despite knowing of the patient's addiction.        Taking a
    practical view of what had transpired, the jury reasonably could
    have regarded the patient-harm testimony as powerful proof both
    that the coconspirator doctors prescribed Subsys in the absence of
    any medical necessity and that they failed to minimize the risk of
    - 68 -
    adverse effects when setting dosages.          In fine, the patient-harm
    testimony was relevant to show that the doctors contravened their
    professional obligations.         See United States v. Singh, 
    54 F.3d 1182
    , 1187 (4th Cir. 1995).       And we think it obvious that evidence
    that the doctors prescribed Subsys outside the usual course of
    professional     practice   while     receiving     kickbacks    constitutes
    evidence relevant to show that the defendants had entered into an
    agreement to bring about exactly that result.            See United States
    v. Rivera-Santiago, 
    872 F.2d 1073
    , 1079 (1st Cir. 1989) (explaining
    that "[t]he actions, as well as the words of the [coconspirators],
    are evidence of the existence and scope of a conspiracy").                 On
    this record, evidence about the exploitation of addiction was
    relevant to show that all of the coconspirators, including the
    defendants, viewed addiction less as a societal problem and more
    as a pathway to predatory profits.
    On the same basis, we dismiss Gurry's contention that he
    "had no connection to prescribers' medical decision-making."              The
    patient-harm testimony is relevant as to Gurry because it helped
    establish the scope of the conspiracy.             See 
    id.
        "The fact that
    [Gurry] participated in one retail link of the distribution chain,
    knowing   that    it   extended     beyond   his    individual    role,   was
    sufficient" to establish relevancy as to him.           
    Id.
    The defendants erect a straw man.           They submit that the
    patient-harm testimony "said nothing about what [they], who had no
    - 69 -
    contact with any of these patients and no knowledge of [what] they
    were affected by Subsys, specifically intended." But as we already
    have discussed, a core component of the conspiracy to distribute
    Subsys was influencing doctors to "push the dose."                 The most
    logical reason for the defendants' unremitting efforts to increase
    dosages was their knowledge that patients on higher doses would
    refill their Subsys prescriptions while patients on lower doses
    would not.    The patient-harm testimony showed vividly just how the
    "effective dose" messaging furthered the scheme.
    At the risk of carting coal to Newcastle, we add that
    the   patient-harm    testimony   also     helped   to   explain   how   the
    defendants could expect doctors to fulfill their commitments to
    Insys representatives, that is, to meet quotas obligating them to
    prescribe inordinately high amounts of Subsys.               The patients
    trusted the doctors; the doctors provided a limited explanation of
    the drug to the patients; and by the time the patients realized
    they were addicted, they were powerless to refrain from seeking
    more and more Subsys.
    To say more about relevancy would be to paint the lily.
    Because the patient-harm testimony tended to show the ins and outs
    of the defendants' scheme, it was within the district court's
    discretion to deem this evidence relevant.          See United States v.
    Hale, 
    857 F.3d 158
    , 171 (4th Cir. 2017).
    - 70 -
    B
    The   defendants     next       argue   that   the   patient-harm
    testimony,   even   if   relevant,    was    unfairly    prejudicial.     In
    examining this claim, we       begin with evidentiary bedrock.             A
    district court may exclude relevant evidence if an objecting party
    can show that "its probative value is substantially outweighed by
    a danger of . . . unfair prejudice." Fed. R. Evid. 403. But under
    Rule 403, one size does not fit all.         Thus, we afford the district
    court "considerable latitude in steadying the balance which Rule
    403 demands."   United States v. Cadden, 
    965 F.3d 1
    , 22 (1st Cir.
    2020) (quoting United States v. Rodriguez-Estrada, 
    877 F.2d 153
    ,
    156 (1st Cir. 1989).
    Through serial rulings, the court below exercised care
    in weighing the considerations affecting the Rule 403 balance.
    From the beginning, the court precluded evidence concerning the
    social consequences of addiction and — in its own words — took
    pains to "carve[] out most inflammatory aspects" of the testimony.
    Gurry, 427 F. Supp. 3d at 203.        Even so, the defendants complain
    that the court did not carve out a sufficiently wide exclusionary
    swath.
    The   defendants'    argument       relies     primarily   on   our
    decision in Kilmartin, 944 F.3d at 315.           Kilmartin, though, is a
    horse of a different hue.     There, the government prosecuted — for
    fraud-related crimes — a defendant who advertised cyanide to
    - 71 -
    suicidal individuals, collected their money, and sent them Epsom
    salts instead.       See id. at 323-24.           At trial, the government
    offered as "anecdotal background evidence" testimony from victims
    (other than those named in the charged counts) who had tried to
    purchase cyanide from the defendant.            Id. at 333.       This testimony
    "went into excruciating detail about the . . . victims' personal
    lives, medical issues, histories of depression, earlier suicide
    attempts, suicidal motivations, and the like."                   Id. at 335.      We
    later described the testimony as "copious," "emotionally charged,"
    and as having "virtually no probative value."             Id. at 337.      Because
    the inordinate potential for prejudice "substantially outweighed"
    the dubious probative value of the anecdotal evidence, we held
    that the district court abused its discretion in admitting that
    evidence.    Id. at 338.
    This case is a world apart from Kilmartin.                 The patient-
    harm testimony here was relatively brief and squarely probative,
    established   that    the     patients   became       addicted    to    Subsys   and
    suffered    withdrawal      symptoms,    shed     a    bright     light    on    the
    prescribing   habits     of   the   coconspirator       physicians,       tied   the
    "effective dose" messaging into the scheme, and catalogued (in
    checklist fashion) many of the ways in which the IRC misrepresented
    patient information.        Perhaps most importantly, the patient-harm
    testimony explained how the charged conspiracy was able to function
    and how it generated product demand.            And, finally, the testimony
    - 72 -
    was concise:    no testifying patient was permitted to dwell unduly
    on the harm that he or she suffered.          Viewed in this perspective,
    the patient-harm testimony was less like the challenged testimony
    in Kilmartin and more like the victim testimony in Cadden, 965
    F.3d at 22 — the admission of which we approved because it was
    relatively    brief   and   the   trial    court   precluded     more     graphic
    details.
    To be sure, the patient-harm testimony packed a punch.
    Nevertheless, the issue is not prejudice simpliciter but, rather,
    whether particular evidence crosses the line into the forbidden
    realm of unfair prejudice.9       See United States v. Pitrone, 
    115 F.3d 1
    , 8 (1st Cir. 1997) ("[I]t is only unfair prejudice against which
    the   law   protects."   (emphasis    in    original)).        The     fact   that
    addiction is ugly does not bar the government from offering
    evidence about it when — as in this case — the defendants' scheme
    has made addiction relevant and probative.                 See, e.g., United
    States v. Morales-Aldahondo, 
    524 F.3d 115
    , 120 (1st Cir. 2008)
    (holding    that,   although   admitted     images   of    child      pornography
    "undoubtedly had an emotional impact on jurors," district court
    "properly    balanced    the   competing    concerns      of   Rule    403"   when
    evidence was probative and court "limit[ed] the number of images

    prejudicial." Rodriguez-Estrada, 
    877 F.2d at 156
    . If it was not
    intended to influence the jury in one way or another, it is
    unlikely that any party would seek to introduce it.
    - 73 -
    presented").     In the last analysis, a "court is not required to
    scrub the trial clean of all evidence that may have an emotional
    impact, where the evidence is part of the Government's narrative."
    Id. at 120 (internal quotation omitted).
    We are aware that the defendants offered to stipulate
    that none of the testifying patients had cancer.                 But such a
    stipulation    was   not   an   acceptable   proxy   for   the    patients'
    testimony.     The scope of the       proffered   stipulation was much
    narrower than the scope of the testimony, and the government was
    entitled to show (for example) other misrepresentations made by
    the IRC. We consistently have rejected parties' attempts to insist
    that district courts accept stipulations that are not commensurate
    substitutes for live proof, see, e.g., Cadden, 965 F.3d at 22, and
    we do so here.
    To sum up, we discern no abuse of discretion in the
    court's construction of the Rule 403 balance.          The patient-harm
    testimony bore on the government's theory of the case in salient
    ways, and the court took prudent steps to soften the emotional
    impact of the testimony. We have stated before that "[o]nly rarely
    — and in extraordinarily compelling circumstances — will we, from
    the vista of a cold appellate record, reverse a district court's
    on-the-spot judgment concerning the relative weighing of probative
    value and unfair effect."       United States v. Mehanna, 
    735 F.3d 32
    ,
    59 (1st Cir. 2013) (quoting Freeman v. Package Mach. Co., 865 F.2d
    - 74 -
    1331, 1340 (1st Cir. 1988)).          This is not so rare an instance, and
    the district court acted within the encincture of its discretion
    under Rule 403 in allowing the challenged testimony.
    C
    The defendants' challenge to the admissibility of the
    patient-harm testimony incorporates one last point.            They contend
    that the patient-harm testimony was cumulative of other proof.
    They note, for example,          that Dr. Awerbuch and Nurse Alfonso
    testified     that   their   Subsys    prescriptions   were   not   medically
    necessary and that Gurrieri and other IRC staffers testified that
    they lied to insurers about patients' conditions.                   Since the
    defendants did not raise this objection below, plain error review
    obtains.      See Taylor, 
    54 F.3d at 972-73
    ; United States v. Nivica,
    
    887 F.2d 1110
    , 1116 (1st Cir. 1989).
    "The plain error hurdle is high," United States v.
    Hunnewell, 
    891 F.2d 955
    , 956 (1st Cir. 1989), and a purported error
    must (among other things) be "clear or obvious" in order to be
    "plain."    United States v. Duarte, 
    246 F.3d 56
    , 60 (1st Cir. 2001).
    Cumulativeness is almost always a matter of degree, and the
    defendants' claim of cumulativeness — if it suggests an error at
    all — at most suggests an error that is neither clear nor obvious.
    See United States v. Sepulveda, 
    15 F.3d 1161
    , 1185 (1st Cir. 1993)
    ("We   have    routinely     found    cumulative   evidence   impotent   when
    - 75 -
    accidentally uncorked.").         Plain error is, therefore, plainly
    absent.
    VI
    Gurry — whom the jury acquitted with respect to the CSA
    and   honest-services    predicates         —   contends   that     the   evidence
    admitted with respect to those predicates unfairly influenced the
    jury's     findings   against    him      on     the   mail-   and    wire-fraud
    predicates.10
    This is,    for all intents and purposes,                a claim of
    prejudicial spillover.       As relevant here, prejudicial spillover
    occurs when the evidence admitted to prove a charge as to which
    the defendant was acquitted "was so extensive, inflammatory, and
    prejudicial that it necessarily spilled over into the jury's
    consideration of [his] guilt on other charges."                   Mubayyid, 
    658 F.3d at 72
    .
    To   determine      whether         an   unacceptable     threat   of
    prejudicial spillover materialized, we must evaluate whether the
    record evinces "a 'serious risk' that the joinder of offenses
    compromised a specific trial right or 'prevent[ed] the jury from
    10Although the other four defendants advanced similar
    contentions in their briefs, those contentions have been rendered
    moot by our vacatur of the district court's partial grant of their
    Rule 29(c) motions. See supra Part III (A)-(D); see also Mubayyid,
    
    658 F.3d at 73
     (holding claim of prejudicial spillover without
    merit after appellate court reinstated the previously vacated
    conviction).
    - 76 -
    making a reliable judgment about guilt or innocence.'"                     
    Id.
    (quoting United States v. Houle, 
    237 F.3d 71
    , 75-76 (1st Cir.
    2001)).   The devoir of persuasion rests with the defendant to show
    "prejudice so pervasive that a miscarriage of justice looms."
    United States v. Trainor, 
    477 F.3d 24
    , 36 (1st Cir. 2007) (quoting
    United States v. Levy-Cordero, 
    67 F.3d 1002
    , 1008 (1st Cir. 1995)).
    In the court below, Gurry argued that the government's
    "accusation" that he and the other defendants intended to coax
    doctors   to    prescribe    Subsys    illegitimately,   coupled   with    the
    patient-harm testimony, tainted the jury's findings against him on
    other matters.       The district court rejected this argument and
    refused to order a new trial on this ground.                See Gurry, 427
    F. Supp. 3d at 196-97.        It found that the patient-harm testimony
    was properly admitted as to all the defendants and all the charged
    predicates and observed that its jury instructions had been custom
    tailored to guard against prejudicial spillover.            See id.
    We review the district court's denial of a new trial
    based   on     allegations   of   prejudicial   spillover    for   abuse   of
    discretion.      See United States v. Neal, 
    36 F.3d 1190
    , 1205 (1st
    Cir. 1994).      We discern none.
    At the outset, it bears mentioning that Gurry's argument
    repastinates much of the same ground covered in our discussion of
    the admissibility of the patient-harm testimony.            See supra Part
    V.   He was charged as a coconspirator and, thus, almost all of the
    - 77 -
    evidence     properly    admitted    against   other   coconspirators    was
    relevant to and independently admissible against him.           See United
    States v. O'Bryant, 
    998 F.2d 21
    , 26 (1st Cir. 1993).           And because
    the patient-harm testimony was independently admissible against
    Gurry, he hardly can be heard to complain about an untoward
    spillover effect.        See 
    id.
         Simply put, the government's case
    against Gurry would have comprised essentially the same evidence
    even if the government had not seen fit to charge him with the
    acquitted predicates.
    We add that Gurry's argument that patient-harm testimony
    likely "incited [the jury's] ire" is severely wounded by his
    acquittal with respect to the CSA and honest-services predicates.
    That   the   jury's     findings    distinguished   among   defendants   and
    differentiated among proposed predicates is strong evidence that
    no spillover prejudice occurred.          See United States v. Williams,
    
    809 F.2d 75
    , 88 (1st Cir. 1986); cf. United States v. Natanel, 
    938 F.2d 302
    , 308 (1st Cir. 1991) ("The introduction of evidence
    against other defendants cannot realistically be viewed as having
    jeopardized [the defendant's] chances on [one count] when the jury
    proved willing to treat the case against [him] on its own merits
    by acquitting him on the other counts.").              Here, moreover, the
    jury differentiated not only between counts but among defendants
    — and that selectivity is "strong evidence" that the jury was not
    blinded by raw emotion but, rather, properly compartmentalized and
    - 78 -
    applied the law to the facts.       United States v. Bailey, 
    405 F.3d 102
    , 112 (1st Cir. 2005); see United States v. Dworken, 
    855 F.2d 12
    , 29 (1st Cir. 1988) (giving credence to "jury's ability to
    segregate the evidence and carefully weigh against which defendant
    it was applicable" (quoting United States v. Richman, 
    600 F.2d 286
    , 299-300 (1st Cir. 1979)).
    Much of the credit for the jury's discernment must go to
    the district court.        The court excluded the most inflammatory
    evidence about the effects of Subsys and prudently instructed the
    jury both to treat each defendant individually and to weigh
    separately the evidence as to each defendant.            As a general rule,
    "instructing the jury to consider each charged offense, and any
    evidence   relating   to    it,   separately   as   to    each   defendant"
    constitutes an "adequate measure[] to guard against spillover
    prejudice."   United States v. Casas, 
    425 F.3d 23
    , 50 (1st Cir.
    2005); see, e.g., United States v. Figueroa, 
    976 F.2d 1446
    , 1454
    (1st Cir. 1992) (holding that "district court minimized any danger
    from prejudicial spillover through its repeated instructions that
    the jury was to give separate consideration to each charge against
    each defendant").     Gurry has not pointed to anything that would
    take this case out of the general rule.
    Little more need be said.       The jury acquitted Gurry with
    respect to the CSA and honest-services predicates while at the
    same time finding the       four other     defendants guilty of those
    - 79 -
    charges.        This result constituted "an uncommonly convincing 'ex
    post validation' of the jury instructions."               Figueroa, 
    976 F.2d at 1454
    .      In    the   circumstances    of    this   case,   Gurry's    claim    of
    prejudicial spillover lacks force, and the district court acted
    well within the ambit of its discretion in refusing to grant him
    a new trial on that ground.
    VII
    During pretrial proceedings, Lee moved for a severance
    of the charges against her.             See Fed. R. Crim. P. 14(a).             The
    district court denied her motion.             Lee assigns error.
    A
    In support of severance, Lee argued below that the
    government charged two distinct conspiracies: one to bribe doctors
    who would prescribe Subsys indiscriminately and another to defraud
    insurers to pay for those prescriptions. From this starting point,
    she asserted that a joint trial would prejudice her because she
    was not personally involved in the second of these conspiracies.
    The district court denied her motion, concluding that Lee had
    failed   to     make   a   sufficient   showing      of   potential    prejudice.
    Specifically, the court found that Lee had "fail[ed] to identify
    any evidence or argument that would not be admissible against her
    in a separate trial" and that her allegations of prejudice were
    wholly conclusory.
    - 80 -
    On appeal, Lee traverses the same terrain.                   Her case
    should have been severed, she submits, because she was a stranger
    to the IRC portion of the wrongdoing.                We review the district
    court's denial of her motion for abuse of discretion.                 See United
    States v. Azor, 
    881 F.3d 1
    , 12 (1st Cir. 2017).
    When — as in this case — an indictment charges a criminal
    conspiracy among multiple defendants, the government enjoys the
    benefit   of    a    rebuttable    presumption     that   a   joint     trial   is
    appropriate.        See United States v. Soto-Beníquez, 
    356 F.3d 1
    , 29
    (1st Cir. 2003) (explaining that "the general rule is that those
    indicted together are tried together"); see also Zafiro v. United
    States,   
    506 U.S. 534
    ,   537     (1993)   (noting    Supreme    Court's
    "repeated[] . . . approv[al] of joint trials" for coconspirators).
    And in cases where joinder is proper, "[w]e must affirm the
    district court's denial of a motion to sever unless the defendant
    makes a strong and convincing showing of prejudice." United States
    v. Richardson, 
    515 F.3d 74
    , 81 (1st Cir. 2008) (internal citations
    omitted); see Azor, 881 F.3d at 12.
    Here, we uphold the district court's refusal to sever
    for two reasons.       First, the record contains substantial evidence
    showing Lee's involvement with the IRC (for instance, evidence
    showing that Lee sought to maximize the number of opt-in forms to
    be transmitted to the IRC and evidence showing that she supervised
    some of Insys's IRC authorization specialists).                Second, because
    - 81 -
    the government charged and proved a single conspiracy and because
    Lee was charged and convicted as a coconspirator, virtually all of
    the   evidence   properly   admitted    against   the   other   defendants
    (including evidence showing that the IRC was an integral part of
    the single conspiracy) was also admissible against Lee.                See
    O'Bryant, 
    998 F.2d at 26
    ; see also Richardson, 
    515 F.3d at 82
    ("[T]his Court has repeatedly refused to overrule a denial of
    severance if substantially the same evidence would have been
    admitted in separate trials.").
    Straining to show that she did not belong in the case,
    Lee identifies 34 witnesses who — she speculates — would not have
    been called to testify had she been tried alone.        But the unadorned
    fact that additional witnesses will be called in a joint trial is
    not a cognizable basis for severance.         The right to a severance
    necessarily entails a showing of prejudice, and Lee offers no
    explanation as to why the testimony of these witnesses (who, in
    her brief's words, "had nothing relevant or incriminating to say
    about Lee") prejudiced her in any way.
    B
    Lee plucks out of thin air a new assault on the denial
    of her motion for a severance.         She contends, for the first time
    on appeal, that joinder was improper under Federal Rule of Criminal
    Procedure 8(b).   This misjoinder, she says, independently demanded
    severance.   Although we normally review the propriety of joinder
    - 82 -
    de novo, see Azor, 881 F.3d at 12, Lee's unpreserved contention
    engenders — at most — plain error review,11 see United States v.
    Greenleaf, 
    692 F.2d 182
    , 187 n.4 (1st Cir. 1982); see also United
    States v. Ackerly, 
    981 F.3d 70
    , 74 (1st Cir. 2020).
    Whatever the standard of review, a claim of misjoinder
    "requires   reversal   only   if    the   misjoinder   results   in   actual
    prejudice."    United States v. Lane, 
    474 U.S. 438
    , 449 (1986); see
    United States v. Bruck, 
    152 F.3d 40
    , 44 (1st Cir. 1998).                 The
    movant must show that her joinder had a "substantial and injurious
    effect or influence in determining the jury's verdict."               Bruck,
    
    152 F.3d at 44
     (quoting Kotteakos v. United States, 
    328 U.S. 750
    ,
    776 (1946)).    Lee's feeble effort to show that her joinder was
    prejudicial falls far short.
    Lee starts with the uncontroversial proposition that
    prejudicial joinder may entitle a defendant to a severance.              See
    Natanel, 
    938 F.2d at 306
    .          Lee has very little to say, though,
    about why her joinder was prejudicial.        Her only argument seems to
    rest on her self-serving conclusion that "the Government misled
    the Court into believing that Lee 'dealt extensively' with the
    11 In all likelihood, the claim of misjoinder — which was
    available before trial but not raised by any pretrial motion — was
    waived. See Fed. R. Crim. P. 12(b)(3)(B)(iv). Here, however, the
    government has not suggested waiver, and we assume for argument's
    sake that the misjoinder claim is subject to appellate review
    (albeit only for plain error).
    - 83 -
    IRC."   This conclusion, in turn, circles back to her protest that
    she had "no criminal association" with the IRC side of the venture.
    As we already have explained, this protest is at odds
    with the record.   In certain cases, evidence at trial may "serv[e]
    as an ex post assurance that joinder was a step founded on a
    reasonable, good faith basis in fact."     
    Id. at 307
    .   So it is here,
    and we hold unhesitatingly that Lee's joinder was appropriate.
    VIII
    Lee's    employment    history     was   unusual     for    a
    pharmaceutical executive:   her most relevant prior work experience
    seems to have been as an exotic dancer at a Chicago-area strip
    club.   Before trial, the government sought leave to introduce
    evidence about Lee's past work and her unorthodox professional
    behavior with Dr. Madison (the notorious pill mill operator).        The
    district court ruled, over Lee's objection, that the proffered
    evidence was "not admissible to prove the Defendants' character,
    but such evidence may be admissible for other purposes, including
    to establish the nature of the relationships between the co-
    conspirators, duress, or relevant corporate culture."        Along the
    same lines, the court ruled that Lee's employment history "[was]
    not admissible to prove [her] character," but "may be intrinsic to
    aspects of the charged offense" and, to that extent, might be
    admissible.   In the end, the court temporized, stating that the
    - 84 -
    proffered evidence "will be admitted if it is otherwise admissible"
    under the federal rules of evidence.
    At    trial,      the   government      offered   evidence    of    Lee's
    employment history.          Burlakoff testified that he first met Lee
    while she was working at a strip club, that he invited her to apply
    for a sales manager position at Insys, and that he sent her résumé
    to Babich.      In order to bolster its theory that Kapoor knew of
    Lee's lack of credentials in either management or pharmaceutical
    sales,   the    government     discussed      at   sidebar    its    intention   to
    introduce an email that suggested that Lee had run an escort
    service.       The   court    refused    to   admit    the   email    but   allowed
    testimony about whether portions of Lee's résumé were incomplete.
    In front of the jury, the prosecutor asked Burlakoff
    whether someone had provided Insys with information that Lee was
    "running an escort service."          The court sustained an objection and
    struck the question.         But that was not the end of the matter.           When
    the parties returned to sidebar, the district court ruled that the
    email    contained     "relevant        information,"        but    directed     the
    prosecutor "to keep the salacious aspect to an absolute minimum."
    Acceding to a defense request for an instruction that the contents
    of the email were not being admitted for the truth of the matter
    asserted, the court told the jurors that they would "hear testimony
    . . . that the company got some information about Ms. Lee that
    suggested that she might not be qualified for the job."                     Because
    - 85 -
    "the    letter    that    [Insys]    received   is   anonymized,"   the   court
    cautioned:
    The letter does not — and I cannot emphasize
    this strongly enough — does not come in for
    the truth of the matter asserted. . . . [T]he
    person that wrote . . . the letter . . . is
    certainly not here. They're not testifying.
    There may be issues of bias. We don't have
    any way to know if what they're saying is true
    or not. You're to consider this information
    only to the effect that [it] had on the company
    and what they did in response to receiving
    this information.
    Burlakoff then testified that Babich had received an
    email about Lee from an "ex-fiancé . . . who had a bone to pick
    with her."      According to Burlakoff, the email questioned why Insys
    would    hire    someone    with    Lee's   background   and   listed   several
    websites.       He checked the websites and found topless photos of
    Lee.    After he informed Babich, Babich consulted with Kapoor, who
    "s[aw] no issue with it" but asked that "those pictures come down
    immediately."      Burlakoff relayed Kapoor's wishes to Lee, who took
    the topless photos down.
    Separately, two sales representatives testified that
    they went to a Chicago nightclub with Lee and Dr. Madison after a
    speaker event.           One testified that Lee "was sitting on [Dr.
    Madison's] lap, kind of bouncing around, and he had his hand sort
    of inappropriately all over her on her chest."                 The other sales
    representative testified that he observed "[v]ery inappropriate
    contact" between Lee and Dr. Madison, such as Dr. Madison placing
    - 86 -
    "[h]is hands . . . all over her, her front and her pants, in her
    shirt" and "heavily kissing" Lee.
    Lee objected to all of this testimony and moved for a
    mistrial, which the district court denied.                She argues that the
    court erred in admitting this evidence because it constituted
    "salacious propensity evidence" that should have been excluded
    under Federal Rule of Evidence 404(b).             She suggests that because
    "the jury heard questions that gave an inference that if Lee worked
    as an escort or operated an escort service for financial gain in
    the past and had topless photos on the internet, it is more likely
    that she committed the charged offense for financial gain."                     In
    the alternative, she suggests that the evidence should have been
    excluded under Rule 403.
    We    review   the    district       court's    admission     of    the
    challenged evidence for abuse of discretion.               See Iacobucci, 
    193 F.3d at 20
    .      We start with Lee's Rule 404(b) challenge.                   Rule
    404(b)'s   propensity     bar    "excludes      only    extrinsic    evidence    —
    'evidence of other crimes, wrongs, or acts' — whose probative value
    exclusively     depends   upon    a    forbidden       inference    of   criminal
    propensity."    United States v. Manning, 
    79 F.3d 212
    , 218 (1st Cir.
    1996) (quoting United States v. Hadfield, 
    918 F.2d 987
    , 994 n.5
    (1st Cir. 1990)).     Evidence intrinsic to the crime charged is not
    precluded under Rule 404(b).          See 
    id.
    - 87 -
    Following     these    guideposts,      we   conclude     that   Rule
    404(b)'s proscription of propensity evidence is inapposite here.
    The probative value of the challenged evidence does not depend
    exclusively on a forbidden inference of propensity but, rather, is
    intrinsic to the crime charged.          Burlakoff's testimony about Lee's
    qualifications (or lack of them) tends to show that neither Kapoor
    nor Lee could reasonably think that Lee was hired as a sales
    manager due to either her executive excellence or her marketing
    skill set.     Instead, the evidence suggests that the defendants'
    scheme to bribe doctors into prescribing Subsys indiscriminately
    offered doctors both money (through the speaker programs) and
    sexual favors.
    So, too, the sales representatives' testimony about
    Lee's   physical    interactions     with    Dr.    Madison    has   independent
    probative value:        that testimony confirms Lee's willingness to
    influence      doctors'     prescription           habits     through    sexual
    interactions.      As Burlakoff made clear, the doctors "prescribe[d]
    strictly based on their relationship with the sales manager."
    Here, the challenged evidence was relevant because it explained
    the background and development of the relationship between two of
    the coconspirators (Lee and Dr. Madison) inasmuch as it showed
    Lee's tactics for getting Dr. Madison "to keep his writing up" and
    because   it   revealed     some    of   the   unprofessional        motivations
    underlying Dr. Madison's prescription habits.                 See United States
    - 88 -
    v. Escobar-de-Jesus, 
    187 F.3d 148
    , 169 (1st Cir. 1999).                    As the
    district court noted, the evidence is "illustrative of [Lee's]
    relationship with [Dr. Madison] and how she's interacting with
    him" to motivate the doctor to prescribe more and more Subsys.
    We   also   reject     Lee's     contention      that   the     jury
    necessarily inferred that she was likely to have committed a crime
    from evidence that she ran an escort service and that topless
    photos of her floated on the internet.              The record contains no
    indication of the evidence being offered or used for that purpose.
    Perhaps more importantly, the district court carefully limited the
    ways in which the jury could put that information to use.                     The
    email came in only to show "the effect that [it] had on the company
    and   what    [the    company]    did   in    response   to   receiving      this
    information."        We long have held that courts may presume that
    jurors will follow the judge's instructions, United States v.
    Spencer, 
    873 F.3d 1
    , 16 (1st Cir. 2017), and Lee has provided no
    reason for us to deviate from that norm.
    Nor did the district court abuse its discretion in
    concluding that the probative value of the challenged evidence was
    not substantially outweighed by its unfairly prejudicial effects.
    We afford district courts appreciable discretion in striking the
    balance that Rule 403 demands.               See Mehanna, 735 F.3d at 59;
    Freeman, 865 F.2d at 1340.              The evidence challenged here was
    probative of one of the ways in which Lee and her superiors
    - 89 -
    attempted to influence prescribers, and it was also probative of
    the defendants' intent to downplay traditional sales strategies
    that focus on patients' needs.         Here, moreover, the district court
    was sensitive to the potential for prejudice, cautioning the
    government to "tone it down" and to avoid the specific details of
    Lee's encounter with Dr. Madison.          In the same spirit, the court
    made certain that the information derived from the email was
    presented to the jury as suspect:          it told the jurors that there
    was no way to find out if the information in the email was true
    and instructed them not to take it for the truth of the matter.12
    We conclude, therefore, that the district court held the Rule 403
    balance   steady   and   true,   and    that   Lee's   claim   of   error   is
    impuissant.
    Lee's appeal from the denial of her motion for a mistrial
    is equally unavailing.      "Declaring a mistrial is a last resort,
    only to be implemented if the taint is ineradicable, that is, only
    if the trial judge believes that the jury's exposure to the
    evidence is likely to prove beyond realistic hope of repair."
    Sepulveda, 
    15 F.3d at 1184
    .      We review the district court's denial
    12Lee argues in passing that the "[a]dmission" of the email
    "would offend" the Confrontation Clause. See U.S. Const. amend.
    VI. This argument collapses of its own weight: the email was
    never admitted into evidence and, in any event, the court told the
    jury that it could not consider the contents of the email for the
    truth of the matter asserted.        Consequently, the right to
    confrontation was not implicated. See United States v. Cabrera-
    Rivera, 
    583 F.3d 26
    , 33 (1st Cir. 2009).
    - 90 -
    of a mistrial for abuse of discretion.                   See United States v.
    Chisholm, 
    940 F.3d 119
    , 126 (1st Cir. 2019).
    In the case at hand, the district court supportably found
    that a mistrial was not required.            Its clear limiting instructions
    and   prompt   striking   of    extraneous      matter,    combined       with   the
    presumption that juries follow the trial court's instructions,
    leads inexorably to a conclusion that the district court did not
    abuse its discretion.
    IX
    Lee    requested    a     jury     instruction       on     supervisory
    condonation.      She asked that the jury be instructed that while
    "Burlikoff [sic] and Babich's knowledge or condoning of activities
    does not by itself constitute a defense or an excuse," evidence of
    their "actions or omissions, or evidence of deficiencies in the
    manner in which they implemented or enforced [Insys's] policies
    and procedures, may be considered . . . to the extent that such
    evidence bears on the issue of whether or not defendant Lee formed
    the required intent to commit the crimes with which [s]he is
    charged."      The   district       court    did   not    give    the    requested
    instruction.      Lee preserved her objection and now assigns error.
    Our review of the district court's eschewal of this
    proposed instruction is for abuse of discretion. See United States
    v. De La Cruz, 
    514 F.3d 121
    , 139 (1st Cir. 2008).                A district court
    is, of course, under no obligation to honor a party's word choices
    - 91 -
    or to parrot proposed language when delivering jury instructions.
    See United States v. DeStefano, 
    59 F.3d 1
    , 2-3 (1st Cir. 1995).
    As a result, we will not second-guess the trial court's rejection
    of a proposed instruction unless the proposed instruction is itself
    substantively correct, was not covered (at least in substance) in
    the charge as given, and touched upon a salient point (such that
    the refusal so to instruct seriously undercut the proponent's
    ability   to   mount   a   particular   claim   or   defense   and   caused
    substantial prejudice).      See 
    id.
    Lee's proposed instruction fails under the second and
    third prongs of this formulation.       The district court's charge, as
    rendered, contained a good-faith instruction, which informed the
    jury that "[t]he 'good faith' of a Defendant is a complete defense
    to the charge in the indictment because good faith on the part of
    the Defendant is, simply, inconsistent with both knowingly and
    willfully agreeing to become a member of the alleged conspiracy
    and specifically intending that a member of the alleged conspiracy
    would commit criminal conduct."        The court added that "[a]n honest
    mistake in judgment or an honest error in management does not rise
    to the level of criminal conduct."        So, the court said, "[i]f the
    evidence in the case leaves . . . a reasonable doubt as to whether
    a Defendant acted with criminal intent or in good faith," the jury
    should "find the Defendant not guilty."
    - 92 -
    This instruction fully permitted Lee to present her
    supervisory      condonation         defense     and,     thus,      forestalled      any
    cognizable claim of prejudice.               Lee demurs, maintaining that the
    court's good-faith instruction did not accommodate her two-pronged
    argument that she "was lawfully following the instructions of her
    employer" and that "Insys condoned her conduct."
    Lee's    claim   of    error     depends     on   an    unrealistically
    cramped reading of the court's good-faith instruction.                        Under this
    instruction, Lee was free to argue that she acted in good faith
    because she subjectively believed that her conduct was lawful and
    that    she    based    that    belief     on     her    employer's         orders,   its
    condonation of her conduct, or both.                    Because of her employer's
    guidance and approval, she might say, her mistake was an honest
    one.   The court's good-faith instruction focused the jury on Lee's
    "actual, subjective beliefs," so the "charge basically did what
    [Lee] wanted it to do."          United States v. Denson, 
    689 F.3d 21
    , 26
    (1st    Cir.    2012).         Because     the    instruction         actually     given
    accommodated both prongs of Lee's argument, the district court's
    refusal   to    use    Lee's    proposed       language     was      well    within   its
    discretion.
    X
    Rowan assigns error to the district court's denial of
    his    mid-trial      motion    to    compel     the    disclosure      of    allegedly
    exculpatory information.              See Brady v. Maryland, 
    373 U.S. 83
    - 93 -
    (1963).   This claim of error harks back to a prosecutor's comment
    to Rowan's counsel, allegedly made during a break in Gurrieri's
    testimony, supposedly mentioning that the government had discussed
    a recording used as an IRC training tool with Gurrieri.           Asserting
    that this recording was a critical piece of evidence in the
    government's case against him, Rowan moved to compel the government
    to produce all communications between Gurrieri and the government
    concerning the recording.
    In response, the government vouchsafed that it "has
    consistently met and exceeded its ethical and legal discovery
    obligations in this case."       There were no further communications
    that were subject to production, the government said, because it
    had   "fully   complied   with   all   of   its   obligations,"   including
    disclosure of all of its interview reports and rough notes.             The
    government added that "[i]f [it] was aware of any exculpatory or
    Brady information in any form, it would have disclosed that
    information in a report, in agent notes, verbally, via email, or
    in some other form."
    The district court denied Rowan's motion "[b]ased on the
    government[']s representations" and its own "understanding of the
    issues in the case as a result of a lengthy trial."               The court
    took the opportunity, though, to remind the government "that its
    [Brady] obligations continue through sentencing."          Rowan moved for
    reconsideration, but to no avail.
    - 94 -
    We review the district court's denial of a motion to
    compel discovery for abuse of discretion.          See United States v.
    Flete-Garcia, 
    925 F.3d 17
    , 33 (1st Cir.), cert. denied, 
    140 S. Ct. 388
     (2019).   This standard of review is not one-dimensional.          See
    Akebia Therapeutics, Inc. v. Azar, 
    976 F.3d 86
    , 92 (1st Cir. 2020);
    United States v. Lewis, 
    517 F.3d 20
    , 24 (1st Cir. 2008).            Within
    it, we review for clear error the district court's factual finding
    that no further document subject to production existed. See United
    States v. Padilla-Galarza, 
    990 F.3d 60
    , 79-80 (1st Cir. 2021).
    Under Brady, the government is obligated "to disclose
    evidence in its possession that is favorable to the accused and
    material to guilt or punishment."        United States v. Prochilo, 
    629 F.3d 264
    , 268 (1st Cir. 2011) (citing, inter alia, Brady, 
    373 U.S. at 87
    ).   Where, as here, a claim of Brady error is advanced, the
    defendant bears the burden of showing "a likelihood of prejudice
    stemming from the government's nondisclosure."          Flete-Garcia, 925
    F.3d at 33.   To make such a showing, he must "articulate with some
    specificity what evidence he hopes to find in the requested
    materials, why he thinks the materials contain this evidence, and,
    finally, why this evidence would be both favorable to him and
    material."    Id. (quoting Prochilo, 
    629 F.3d at 269
    ).              And in
    determining   whether   the   evidence    sought   is   material,   "[t]he
    question is not whether the defendant would more likely than not
    have received a different verdict with the evidence, but whether
    - 95 -
    in its absence he received a fair trial, understood as a trial
    resulting in a verdict worthy of confidence." United States v.
    Josleyn, 
    206 F.3d 144
    , 152 (1st Cir. 2000) (quoting Strickler v.
    Greene, 
    527 U.S. 263
     (1999)).
    Rowan has utterly failed to make the requisite showing.
    The most prominent fly in the ointment is that he has failed to
    establish that the evidence he seeks actually exists.                   Although
    Rowan conclusorily asserts that "such communications must have
    occurred," all three prosecutors (including the prosecutor whom
    the    defense   identified     as   having   mentioned      the    government's
    purported discussion with Gurrieri) signed the pleading in which
    the government insisted that it had "withheld nothing."                Given the
    unequivocal nature of the government's representations and the
    experience gleaned by the court in              presiding over        this case
    (including protracted pretrial proceedings, discovery disputes,
    and a lengthy trial), we decry no clear error in the court's
    determination     that    the   claimed     evidence   did    not    exist.    A
    defendant's naked assertion that a particular communication "must
    have    occurred,"   no     matter    how     vociferously     expressed,     is
    insufficient to undermine a reasoned judicial determination that
    no such communication actually exists. See United States v. Duval,
    
    496 F.3d 64
    , 75 (1st Cir. 2007); cf. Padilla-Galarza, 990 F.3d at
    80 (holding, in Jencks Act context, that "the government cannot be
    - 96 -
    expected to produce that which has never existed").    We therefore
    reject Rowan's claim of Brady error.13
    XI
    Following the adverse jury verdicts, Simon — represented
    by successor counsel — moved for a new trial.    See Fed. R. Crim.
    P. 33.    Among the grounds asserted in support of this motion, he
    averred that his trial counsel had been handicapped by a conflict
    of interest.    Specifically, he averred that his trial counsel,
    Steven Tyrrell, was conflicted because the law firm in which
    Tyrrell was a principal — Weil Gotshal & Manges LLP (Weil) — was
    representing Insys in a bankruptcy restructuring at the same time
    that Tyrrell was representing Simon in this case.     The district
    court disagreed and refused to order a new trial.     Simon appeals
    that ruling.
    Simon's conflict-of-interest claim has its roots in an
    internal investigation that Insys conducted some three years prior
    13 We add that Rowan's explanations for why the alleged
    evidence would be exculpatory and material are unconvincing: they
    are woven with nothing more than wispy threads of speculation and
    surmise.    Mere conjecture that certain communications "might
    contain exculpatory evidence" without "any supporting evidence or
    arguments to indicate this was, in fact, the case," is inadequate
    to ground a claimed Brady violation. United States v. Brandon, 
    17 F.3d 409
    , 456 (1st Cir. 1994); see Flete-Garcia, 925 F.3d at 34
    (concluding that "district court's refusal to compel production of
    requested information is not an abuse of discretion" when "theory
    of materiality is based entirely on conjecture"); Prochilo, 
    629 F.3d at 269
     (explaining that defendant's Brady showing "cannot
    consist of mere speculation").
    - 97 -
    to the start of Tyrrell's representation of Simon.             In December of
    2013, Insys received a subpoena from the Department of Justice.
    Insys immediately retained Skadden, Arps, Slate, Meagher & Flom
    LLP (Skadden) to serve as its outside investigations and compliance
    counsel.    Skadden conducted a thorough investigation, interviewed
    numerous    Insys      employees,   reviewed   a    wide   range    of   company
    practices, and offered advice to Insys's board of directors.
    Years passed and — in 2017 — Simon retained Tyrrell to
    represent him in the case at hand.                The following year, Insys
    turned     to   Weil    in    connection   with    anticipated      chapter    11
    proceedings.      When Tyrrell became aware of his firm's potential
    representation of Insys, he discussed the matter with Simon.
    Tyrrell informed Simon that — should his representation of Simon
    continue — he would be "walled off" from the Weil team handling
    Insys's    bankruptcy        reorganization.       Simon   assented      to   this
    arrangement.
    In due course, Weil signed an engagement letter with
    Insys, which explicitly permitted Tyrrell to act adversely to Insys
    in connection with his representation of Simon.                    Weil quickly
    instituted screens to prohibit the two teams from reviewing,
    discussing, or sharing information.
    We fast-forward to June of 2019. After the jury returned
    its verdicts, Simon queried Tyrrell about Weil "representing Insys
    in its bankruptcy case."         Tyrrell reminded Simon of their earlier
    - 98 -
    conversation, described the "wall" that was in place, and assured
    Simon that "there is no sharing of information or interaction."
    Simon renewed his queries the following month, calling Tyrrell's
    attention specifically to the internal investigation that Skadden
    had overseen.    Tyrrell responded that the internal investigation
    had ended before the criminal case began and reiterated that Weil's
    representation    of     Insys    in     the    bankruptcy    proceedings      was
    unrelated to the criminal case.
    Unassuaged, Simon retained fresh counsel and moved for
    a new trial on the ground that Tyrrell had been laboring under a
    conflict of interest.       He alleged that Weil's representation of
    Insys had inhibited Tyrrell and prevented him from seeking to
    obtain the findings of Insys's internal investigation into the
    marketing and sale of Subsys.             Although Insys had consistently
    asserted that those materials were shielded by the attorney-client
    privilege, Simon argued that a different (conflict-free) attorney
    could have pierced the privilege.                The government opposed the
    motion.   The district court denied relief, concluding that Simon's
    proffered alternative strategy was not plausible.               See Gurry, 427
    F. Supp. 3d at 217.
    We   review    the    district       court's   factual   findings    in
    connection with the conflict-of-interest claim for clear error but
    afford de novo review to the court's ultimate conclusion.                      See
    Reyes-Vejerano v. United States, 
    276 F.3d 94
    , 97 (1st Cir. 2002).
    - 99 -
    Under the Sixth Amendment, a defendant has a right to conflict-
    free counsel.       See United States v. Ponzo, 
    853 F.3d 558
    , 574 (1st
    Cir. 2017); U.S. Const. amend. VI.           That right, though, does not
    protect a defendant from an attorney's "mere theoretical division
    of loyalties."       
    Id. at 575
     (quoting Mickens v. Taylor, 
    535 U.S. 162
    , 171 (2002)).       To prevail on a conflict-of-interest claim, a
    defendant    must    show   that   "'a   conflict   of   interest   actually
    affected' the lawyer's 'performance.'"          
    Id.
     (quoting Mickens, 
    535 U.S. at 171
    ).       Such a showing requires a demonstration "that (1)
    the lawyer could have pursued a plausible alternative defense
    strategy or tactic and (2) the alternative strategy or tactic was
    inherently in conflict with or not undertaken due to the attorney's
    other interests or loyalties."           
    Id.
     (quoting United States v.
    Colón-Torres, 
    382 F.3d 76
    , 88 (1st Cir. 2004)).
    We conclude — as did the court below, see Gurry, 427 F.
    Supp. 3d at 217-19 — that no actual conflict of interest existed
    because   piercing     attorney-client     privilege     to   lay   bare   the
    findings of Skadden's internal investigation was not a plausible
    defense strategy. According to Simon, this proposed strategy would
    have offered "material from Skadden's internal investigation to
    substantiate a good-faith defense."           This must be so, he muses,
    because Skadden "apparently . . . did not advise Insys to shut
    down the ISP, to close the IRC, or to fire or discipline Mr.
    Simon."     Building on this rickety foundation, Simon argues that
    - 100 -
    the seeming absence of such advice must mean that Skadden concluded
    that Insys's operations were beyond reproach.                      So, Simon's thesis
    runs,   Skadden's          internal    investigatory        materials    "would    have
    revealed      the    evidentiary        basis    —    facts,      documents,    witness
    testimony — underlying Skadden's findings and advice, which [his]
    defense counsel could have marshaled to use at trial."
    This    proposed        strategy       is    both   substantively        and
    strategically bankrupt.               First and foremost, Simon's allegation
    that    the   findings       reached     during      the    investigation       must   be
    favorable     to     him    is   anchored   on       abject    speculation.       Simon
    consistently has acknowledged that he has never been "privy to the
    details of [outside counsel's] findings and advice."                           Skadden's
    findings are, he confesses, "unknown to [him]."                         Knowledge is
    essential to the making of value judgments, and saying that
    something is "unknown" is tantamount to an admission that its
    favorability cannot be ascertained.
    Despite this void, Simon self-servingly surmises that
    the materials generated during the investigation must bolster his
    defense because Skadden interviewed him and — subsequent to that
    interview and the completion of Skadden's investigation — "nobody
    ever counseled [him] to modify his own practices or imposed any
    discipline or punishment on him for wrongdoing."                          Simon also
    suggests that since the IRC did not shut down, an inference is
    warranted that Skadden did not advise Insys to cease operations.
    - 101 -
    Piling inference upon inference, he then suggests that Skadden
    must have refrained from giving such advice because it found
    Insys's business practices aboveboard.   In other words, Simon asks
    us to assume that the materials would be exculpatory simply because
    the internal investigation neither "resulted in [any] adverse
    employment action against [him]" nor brought about any changes in
    day-to-day IRC operations.    Arriving at that assumption, though,
    elevates hope over reason. Given the complicity of so many company
    hierarchs in the scheme, the unknown time span covered by the
    internal investigation, and the lack of congruity between that
    time span and the life of the conspiracy, Insys's failure to either
    take adverse action against Simon or to modify the IRC's modus
    operandi may well have other more compelling explanations.
    In all events, the district court had ample reason to
    infer that the findings of the internal investigation were likely
    detrimental to Simon's defense.   The government and the defendants
    engaged in considerable pretrial skirmishing as to whether the
    government could elicit testimony from an Insys compliance officer
    who coordinated the investigation.   See id. at 218.   Her testimony
    would have focused on her conclusion that the IRC was engaging in
    insurance fraud, id. — a conclusion that Simon would just as soon
    have the jury not hear.      So, too, other evidence in the record
    makes it likely that the evidence Simon seeks would not have been
    exculpatory.   As we already have pointed out, see supra Part
    - 102 -
    III(C),   the    record    includes      substantial     evidence      of   Simon's
    knowledge of illegitimate Subsys prescriptions and his attempts to
    increase their volume, his knowledge of the IRC's fraudulent
    representations to insurers, and the like.               Viewing the record in
    its entirety, Simon's notion that Insys permitted him to continue
    working because his work was legitimate seems far less plausible
    than the notion that he was kept in place because his work
    furthered the ongoing criminal scheme.                 Cf. Gurry, 427 F. Supp.
    3d. at 220 ("The evidence at trial indicated that although Insys
    hired compliance personnel and a general counsel after receiving
    the subpoena in December 2013, these individuals were largely
    viewed as obstacles to the success of the sales force and the
    company.").     Considering the improbability of Simon's assumption,
    his afterthought defense strategy cannot be said to possess even
    a patina of plausibility and, thus, cannot be considered a viable
    strategy.     See United States v. Cardona-Vicenty, 
    842 F.3d 766
    , 773
    (1st   Cir.    2016);   see     also   Ponzo,    853    F.3d   at   577     ("[M]ere
    speculation      does     not   suffice     to    show    a    Sixth      Amendment
    infraction.")
    To complete the picture, we note that the proffered
    strategy was not only implausible but also entailed significant
    strategic risks.        It is hornbook law that forgoing "a strategy
    that could inculpate the defendant does not constitute an actual
    - 103 -
    conflict."   Ponzo, 853 F.3d at 576.      That is precisely the sort of
    strategy that Simon now embraces.      We explain briefly.
    It is luminously clear that piercing the attorney-client
    privilege would have been fraught with peril.           Success in that
    endeavor would have opened the floodgates for damaging testimony
    from Insys's compliance officer, in-house counsel, and others
    involved in the internal investigation.            The potentially dire
    consequences of such a strategy explain why the other defendants
    — even though most of them would have had at least as good a chance
    as Simon to benefit from the allegedly exculpatory evidence —
    chose, through independent and highly skilled counsel, not to buck
    Insys's attorney-client privilege.      Instead, they banded together
    and asked the district court, in their own words, to "preclude the
    government   from   eliciting   at   trial   any   testimony   regarding
    privileged communications between Insys or its Board of Directors
    . . . and the company's in-house or outside counsel."          To put it
    bluntly, they all went to the mat to block the government from
    introducing the findings of the internal investigation.         The fact
    that no other defendant sought to pierce Insys's attorney-client
    privilege is a telling indication that this strategy was neither
    likely to be helpful to the defendants nor free from significant
    risks of further inculpating them.        Cf. Brien v. United States,
    
    695 F.2d 10
    , 16 (1st Cir. 1982) (giving weight to "the fact that
    none of [defendant's] other co-defendants, even though they had
    - 104 -
    independent counsel," sought the particular evidence).            This is
    far removed from the kind of alternative defense strategy that can
    undergird a Sixth Amendment claim.        See Ponzo, 853 F.3d at 576.
    If more were needed — and we do not think that it is —
    Simon also has failed to establish a meaningful relationship
    between   the    findings   of   the   internal   investigation   and   his
    proffered good-faith defense.          Such a defense asks the jury to
    determine what the defendant's "actual, subjective beliefs" may
    have been.      Denson, 689 F.3d at 26.     Because Simon has never been
    privy to the findings of the investigation, those findings could
    not have informed his subjective beliefs.14         See United States v.
    Zayyad, 
    741 F.3d 452
    , 461 (4th Cir. 2014); United States v.
    Dynalectric Co., 
    859 F.2d 1559
    , 1574 n.19 (11th Cir. 1988).
    14At trial, attorney Tyrrell did press a condonation defense
    on Simon's behalf:    he argued that "when [Simon] started, the
    actions that he took were in line with the strategies that were
    mapped out by the company's leaders and communicated to the entire
    sales force, and there's no evidence that [he] knew or understood
    that any aspect of those strategies was illegal." Because this
    defense substantially covered the defense that Simon now says was
    impaired and because the findings of the internal investigation
    remain largely shrouded in mystery, it is apparent to us that Simon
    has failed to articulate any benefit that his proposed strategy
    plausibly might have achieved. Thus, there is no basis to conclude
    that Tyrrell's choice to refrain from trying to pierce the
    attorney-client privilege "actually affected the adequacy of
    [Simon's] representation." Familia-Consoro v. United States, 
    160 F.3d 761
    , 764 (1st Cir. 1998) (quoting Cuyler v. Sullivan, 
    446 U.S. 335
    , 349 (1980)); cf. Brien, 
    695 F.2d at 15
     (finding no actual
    conflict of interest when "the tactics [defendant] suggests that
    his attorney could have pursued appear to be merely hypothetical
    choices that in reality could not have benefited [him]").
    - 105 -
    That ends this aspect of the matter.              To prevail on a
    Sixth Amendment conflict-of-interest claim, "the conflict must be
    real."   Brien, 
    695 F.2d at 15
    .        The conflict of interest that Simon
    ascribes to his trial counsel is purely theoretical and, thus,
    does not      come close to supporting           a claim of      constitutional
    dimension.      See 
    id.
           We are not in the business of granting
    "undeserved windfall[s]" to defendants who merely point to any
    course   of    action   not   taken    by    their   attorney    and   cry   foul.
    Cardona-Vicenty, 842 F.3d at 774 (internal quotation omitted).                  It
    is exactly that kind of windfall that Simon is seeking.                His quest
    goes begging because the district court was on solid ground in
    denying his conflict-of-interest claim.
    XII
    Gurry contends that the district court blundered in
    denying his motion for a new trial.             He argues that the evidence
    against him was "remarkably thin" and that the government's case
    turned on the "uncorroborated" word of one cooperating witness —
    Gurrieri.
    Where, as here, a new trial motion is based upon the
    weight of the evidence, a district court should not grant a new
    trial "unless it is quite clear that the jury has reached a
    seriously erroneous result."          United States v. Rothrock, 
    806 F.2d 318
    , 322 (1st Cir. 1986) (quoting Borras v. Sea-Land Serv., Inc.,
    
    586 F.2d 881
    , 887 (1st Cir. 1978)).             In a nutshell, such a remedy
    - 106 -
    should    be     granted       sparingly     and     only    when    the     evidence
    preponderates heavily against the jury's verdict or a miscarriage
    of justice otherwise looms.               See United States v. Merlino, 
    592 F.3d 22
    , 32 (1st Cir. 2010).            We review a district court's denial
    of such a motion solely for abuse of discretion.                 See United States
    v. Ruiz, 
    105 F.3d 1492
    , 1501 (1st Cir. 1997).
    The record comfortably supports Gurry's convictions on
    the mail- and wire-fraud predicates. He advised employees to "ride
    the gray line" with insurers and use the "spiel" to obscure the
    patients'      lack   of   a   cancer     diagnosis.        In   addition,       he   led
    strategic planning for the IRC, attended the daily 8:30 a.m.
    management calls as the IRC's "mouthpiece," listened to accounts
    of the IRC's deceptive practices during those daily calls, directly
    supervised Gurrieri (who instructed employees to report false
    medical rationales for prescriptions and bogus lists of tried-and-
    failed medications), approved spurious patient-specific reports of
    difficulty swallowing,           and enforced IRC authorization quotas.
    This     evidence     supports      the     jury's     conclusion         that    Gurry
    deliberately participated in Insys's defrauding of insurers — a
    scheme    that   involved       bribing    doctors     (through     the    mails)      to
    generate prescriptions and misrepresenting (through the wires)
    patients' medical histories and needs.
    In resisting this conclusion, Gurry focuses                          single-
    mindedly on Gurrieri's credibility.                Without that testimony, he
    - 107 -
    suggests, the evidence against him would be weakened to a point
    where the adverse jury verdict would topple.
    Gurry's    single-minded    focus    means    that   he    has   left
    himself with a steep uphill climb:               "the district court must
    generally    defer    to   a   jury's   credibility       assessments"       when
    evaluating a motion for a new trial.           Merlino, 
    592 F.3d at 32
    .        On
    appeal, we may not "second guess the [district] judge's refusal of
    a new trial and the jury's willingness to accept the essentials of
    [a government witness's] account of the events."            United States v.
    Pitocchelli, 
    830 F.2d 401
    , 403 (1st Cir. 1987) (affirming denial
    of new trial when trial court elected to leave "to the jury the
    ultimate decision as to whether it believed" disputed testimony).
    Even if we set to one side the steepness of this slope,
    Gurry has not shown that the jury's verdict was seriously flawed.
    He offers nothing that is sufficient to discredit the inference
    that he purposefully bought into the IRC's tactics.                   We briefly
    inspect his main contention — that Gurrieri was not to be believed
    — and explain why we find that contention wanting.
    First, Gurry emphasizes Gurrieri's decision to testify
    as a cooperating witness.       He rates this as a reason to disbelieve
    her testimony.       But Gurry's rating system is out of kilter:               he
    fails to take into account the jury's prerogatives.               The district
    court   appropriately      instructed    the     jury    that    Gurrieri     was
    cooperating with the government and that her testimony therefore
    - 108 -
    ought to be considered "with particular care and caution."       Given
    this cautionary instruction, it was within the jury's province to
    choose whether to believe or disbelieve Gurrieri's testimony.        See
    United States v. Appolon, 
    695 F.3d 44
    , 55 (1st Cir. 2012).
    Next,   Gurry   declares   that   Gurrieri's   testimony   was
    "uncorroborated."   This declaration is specious.15 Other witnesses
    and documents substantiated the inference that Gurry both knew of
    and supported the IRC's corrupt tactics.        For instance, a sales
    manager testified that she toured the IRC with Gurry, and that
    they listened as an employee used deceptive tactics to obtain
    Subsys authorization from an insurer over the telephone.         Then,
    too, Babich testified that Gurry was part of the "primary group"
    of senior executives who participated in the daily 8:30 a.m.
    management calls, that Gurry was in charge of communicating to
    that group "any highlights both positive and negative that they're
    seeing in the IRC," that those highlights were informed by Gurry's
    communications with Gurrieri, and that those daily calls discussed
    the IRC's deceptive tactics (including the promiscuous use of
    15We do not mean to imply that corroboration was a sine que
    non to a conviction. It was not. See United States v. Martínez-
    Medina, 
    279 F.3d 105
    , 115 (1st Cir. 2002) (holding that the
    "uncorroborated testimony of a government informant is . . . enough
    to convict" because "the law of this circuit . . . leaves in the
    hands of the jury decisions about credibility of witnesses 'so
    long as the testimony is not incredible or insubstantial on its
    face'" (quoting United States v. Andujar, 
    49 F.3d 16
    , 21 (1st Cir.
    1995))).
    - 109 -
    "dysphagia" references and the "spiel").            Babich also testified
    that the dysphagia gambit was discussed by Gurrieri in front of a
    group that included Gurry.
    There was also documentary corroboration.      More than one
    piece   of    this   corroboration   originated    with   Gurry,      who   (for
    example) sent himself an email reminder about employee training on
    the difference between breakthrough cancer pain and breakthrough
    pain.     Similarly, he sent a detailed email to sales managers
    enumerating strategies that were crafted to prompt unwarranted
    insurer      approvals.    Additionally,   he     was   copied   on    several
    inculpatory emails, including emails about "the issue that arose
    with Dr. Chun's pharmacy" and the direct shipments of Subsys to
    Dr. Ruan's pharmacy for the purpose of ensuring "uninterrupted
    delivery to patients."       Corroboration may come in various forms
    and shapes, and we find significant corroboration for Gurrieri's
    testimony in this record.
    Gurry presses his attack on Gurrieri's credibility in
    other ways as well.       For instance, he makes a frontal assault on
    Gurrieri's testimony that he maintained an office near hers at the
    IRC.      In this regard, he notes that two witnesses testified
    otherwise.     That may be so, but it is up to the jury to decide who
    to believe — and that is especially true when witnesses offer
    inconsistent versions of the facts.         See United States v. Patel,
    
    370 F.3d 108
    , 112 (1st Cir. 2004).         And to tie a bow on it, even
    - 110 -
    if we assume, for argument's sake, that Gurrieri's recollection
    was inaccurate on this one point, the jury was still entitled to
    credit other aspects of her testimony that were unfavorable to
    Gurry.   Because a witness's testimony is not a monolith, it was
    within the jury's purview to "credit some parts of [Gurrieri's]
    testimony and disregard other potentially contradictory portions."
    United States v. Sabean, 
    885 F.3d 27
    , 37 (1st Cir. 2018) (quoting
    United States v. Alicea, 
    205 F.3d 480
    , 483 (1st Cir. 2000)).
    Gurry also posits that Gurrieri's testimony that she was
    following Gurry's directions is contradicted by her "eagerness to
    take credit for the IRC's success" in the moment. Gurry's argument
    rests on a kernel of truth:     Gurrieri did claim credit for the
    "creat[ion] [of] the IRC."   But nothing about that claim undercuts
    her testimony that she consulted with Gurry on key decisions, that
    he sanctioned the IRC's deceptive tactics, and that he directed
    her to undertake specific acts of fraud (including the submission
    of authorization requests containing fictious medication lists).
    Gurry has one last shot in his sling.   He complains that
    only Gurrieri characterized him as dishonest.   Other witnesses, he
    says, described him as disciplined, quiet, polite, respectful,
    supportive, and stiff. These traits, he tells us, are inconsistent
    with the government's attempted depiction of him as a racketeer.
    - 111 -
    We are not so sanguine.       A quiet, polite, and respectful
    demeanor is simply not a warranty of good behavior.16               Choir boys
    and curmudgeons alike can commit conspicuously corrupt crimes.              It
    was the jury's task to weigh the salience, if any, of Gurry's
    positive traits against the specific evidence of his less-than-
    savory actions.      Given the deference that we afford juries in
    regard to credibility calls, we cannot say that the jury in this
    case    either   misweighed    the    evidence   or   reached   a    seriously
    erroneous result.
    This door is shut.         The jury was entitled to credit
    Gurrieri's testimony, and the district court did not err in denying
    Gurry's motion for a new trial.
    XIII
    The defendants sought a new trial on the ground that
    prosecutorial     misconduct     infected      the    government's     closing
    argument.   The district court denied their motion, and all of them
    — Gurry directly, and the rest by adoption — now appeal.
    We set the stage.        During the rebuttal portion of his
    closing argument, the prosecutor sought to establish that the
    defendants specifically intended physicians to prescribe Subsys
    This verity has been part and parcel of the human experience
    16
    from time immemorial. Over four centuries ago, the Bard of Avon
    famously wrote "To beguile the time, look like the time — bear
    welcome in your eye, your hand, your tongue.         Look like the
    innocent flower, but be the serpent under't." William Shakespeare,
    Macbeth, act 1, sc. 5 (circa 1606).
    - 112 -
    outside the usual course of professional practice.                      He told the
    jury:
    People intend [the] reasonably foreseeable
    consequences of their actions.      It is as
    though, if I took a gun and fired it into the
    audience, which I'm not going to do, I don't
    intend to shoot any particular individual, but
    I know somebody's going to get hit. And when
    the defendants arm these doctors with all
    these bribes and all these incentives, they
    were creating a loaded gun.
    None of the defendants interposed a contemporaneous objection.
    In the same phase of his closing argument, the prosecutor
    referred   to    evidence    that    defendants   had    hired      a    compliance
    officer.    He    noted     that    the   defendants    "had   no       interest   in
    compliance prior to that" and that the compliance officer "told
    you, when she was hired in April of 2014, that she was being
    frustrated in her efforts." The prosecutor then stated, "regarding
    Mr. Gurry, who was running the IRC, who is responsible for the
    IRC, that's his job.           As a corporate officer, he bears the
    responsibility."     This time, the defendants objected.
    The prosecutor also stated:
    After nine weeks of trial, there should be no
    doubt, in anybody's mind here, that there was
    a massive insurance fraud here, happened
    every day, day in and day out. And there was
    a massive bribery scheme involved. I think
    the defendants concede as much, but what they
    want to sit here and say to you is that these
    men and women who ran this company, who were
    the managers, had no idea what was going on.
    Sort of like that scene from Casablanca, I'm
    - 113 -
    shocked to find out there's illegal gambling
    in this place.
    Along this same line, the prosecutor argued that the defendants
    "incentivized these doctors" to prescribe Subsys frequently and at
    high doses, "and they can't sit here and tell you, now, that they
    didn't   intend   for    that    to    happen."     The   defendants     did   not
    contemporaneously object to either of these comments.
    At the conclusion of the government's rebuttal, the
    district court gave a curative instruction in response to the
    objection relating to Gurry's corporate-officer status.                  It told
    the jury that "the corporation, Insys, is not on trial here.                   The
    individuals are on trial and your verdict must turn on your
    assessment of the culpability of them as individuals and not as
    corporate officers."          Neither side objected to this instruction.
    Several days later — but before jury deliberations began
    — the defendants sought additional curative instructions or in the
    alternative, a mistrial.              In support, they identified several
    instances of alleged prosecutorial misconduct:
    •    They    alluded       to   the    comment      about   Gurry's
    corporate-officer status and argued that they could
    not    be    held    criminally    liable     merely   for   the
    wrongdoing of subordinates.
    •    They    calumnized      the     prosecutor's    "loaded      gun"
    analogy      and    asserted     that   the   statement      that
    - 114 -
    "[p]eople     intend    [the]   reasonably        foreseeable
    consequences of their actions" deviated materially
    from    the   specific-intent         element     of     a     RICO
    conspiracy charge.
    •   Observing that none of them had elected to testify,
    the    defendants      raised   the     specter        that    the
    prosecutor's rebuttal argument had "made veiled
    reference to the fact that Defendants had pressed
    various factual arguments at trial without taking
    the witness stand."
    The district court responded with an offer to give additional
    curative   instructions.         The     court   then     circulated           draft
    instructions; defense counsel proposed revisions; and the court
    accepted all but one of the proposed revisions.17            The court read
    its prepared charge to the jury and followed up by reading the
    supplemental instructions.       In pertinent part, the supplemental
    instructions admonished:
    At least some of the defendants were at
    relevant times corporate officers or managers
    with responsibility for their departments
    and/or subordinates.      The fact that a
    defendant had an executive or managerial
    position at Insys is not alone enough to
    convict the defendant of the RICO conspiracy
    charge in the indictment.
    17 Rowan requested that the court tell the jury that the
    challenged comment "was not a correct statement of the law." The
    court declined that request.
    - 115 -
    A healthcare company executive's or manager's
    failure to correct or prevent misconduct at
    the company does not alone constitute a
    violation of the RICO statute.       In other
    words, even if you think that a defendant
    should have known about certain conduct,
    should have done more to correct or prevent
    such conduct or should be responsible for the
    conduct of company employees, you cannot
    convict the defendant on this basis.
    As I already told you bribes and kickbacks
    alone are insufficient to convict in this
    case. For you to find an agreement regarding
    the racketeering act of illegal distribution
    of a controlled substance, honest services
    mail fraud or honest services wire fraud, you
    must find that defendants agreed to and
    specifically    intended     for     healthcare
    practitioners to write Subsys prescriptions
    outside of the usual course of professional
    practice and without legitimate medical
    purpose.     Under the law, knowledge of
    foreseeable consequences without more is not
    enough to establish that someone specifically
    intended certain conduct.         Rather, the
    government must prove that the defendant acted
    with a bad purpose or with the object of
    committing a prohibited act, here, for the
    controlled substance and honest services
    predicates, having healthcare practitioners
    prescribe Subsys outside of the usual course
    of   professional    practice    and    without
    legitimate medical purpose.
    . . .
    Finally, you should not interpret anything
    that was said in this case as a comment on the
    fact that defendants chose not to testify. As
    I've already instructed you, defendants have
    an absolute constitutional right not to
    testify.   And you cannot draw any inference
    from the fact that they exercised their
    rights.    You cannot consider or discuss
    defendants' choices not to testify during your
    deliberations.
    - 116 -
    After giving these supplemental instructions, the district court
    asked if any party wanted to be heard at sidebar.               Receiving no
    affirmative response, the court instructed the jury to start its
    deliberations.
    Following the adverse jury verdicts, the                  defendants
    renewed their prosecutorial misconduct claims in their new-trial
    motions.   Those motions were uniformly denied.           See Gurry, 427 F.
    Supp. 3d at 201.
    Although we review the district court's order denying a
    new trial for abuse of discretion, see Merlino, 
    592 F.3d at
    32
    n.5, we evaluate de novo their claims of error involving the
    propriety of the government's closing argument, see United States
    v. Kuljko, 
    1 F.4th 87
    , 94 (1st Cir. 2021); United States v.
    Carpenter, 
    736 F.3d 619
    , 626 (1st Cir. 2013).            We start with the
    claims of error arising out of the government's comments about
    Gurry's corporate-officer status and the alleged allusions to the
    defendants' failure to testify.           Those claims of error share a
    common characteristic:        the defendants do not assert that the
    challenged comments were so toxic that no cautionary instructions
    could   have   saved   the   day   but,   rather,    assert   only    that   the
    cautionary     instructions    given      by   the   district    court       were
    insufficient.
    - 117 -
    The architecture of the defendants' assertions shapes
    the contours of our inquiry.            This architecture places waiver
    principles front and center.        We have explained that "when the
    'subject matter [is] unmistakably on the table, and the defense's
    silence is reasonably understood only as signifying agreement that
    there was nothing objectionable,' the issue is waived on appeal."
    Soto, 799 F.3d at 96 (quoting United States v. Christi, 
    682 F.3d 138
    , 142 (1st Cir. 2012)).        One application of this rule occurs
    when "the district court informed the [parties] exactly how it was
    planning to instruct the jury" and "sought their feedback," with
    the result that a party's counsel "affirmatively stated there was
    no objection" or "remained silent."           Soto, 799 F.3d at 96.      In
    that circumstance, an appellate court is free to consider the
    instructions approved by that party.          See id.   Any claim that the
    instructions are inadequate is deemed waived.           See id.
    With respect to the corporate-officer comment and the
    alleged references to the defendants' failure to testify, this is
    such   a   case.     The    defendants    sought    curative   instructions
    addressing    specific     components    of   the   government's   rebuttal
    argument and the district court obliged by circulating proposed
    instructions.      The court invited edits and — in so far as the
    proposed instructions pertained to the corporate-officer comment
    and the comments allegedly touching upon the defendants' failure
    to testify — accepted all the proposed edits.           The court then read
    - 118 -
    the edited instructions to the jury.                  After doing so, the court
    invited counsel to approach sidebar, yet counsel declined the
    invitation.     That declination unambiguously signified approval of
    the supplemental instructions as given and constituted a waiver of
    the defendants' arguments on those points.                 See id.
    To   be    sure,    the    defendants        now    argue   that    waiver
    principles apply only to "the court's instruction-in-chief, [but]
    not to curative instructions."          This is so, they say, because only
    the former "result[s] from an iterative process of give and take
    between the parties and the court."              Here, however, the transcript
    shows beyond hope of contradiction that such an iterative process
    took place with respect to the curative instructions. In addition,
    we   previously    have   found      that   waiver      principles     apply       with
    undiminished      force   to    claims      of     error       targeting    curative
    instructions.      See, e.g., United States v. Charriez-Rolón, 
    923 F.3d 45
    , 53 (1st Cir. 2019).                 We hold, therefore, that the
    defendants'     claims    of   error     regarding       the     corporate-officer
    comment and the alleged comments on the defendants' failure to
    testify are unavailing.
    This      leaves    the   claim       of    error     relating     to   the
    prosecutor's use of the "loaded gun" metaphor.                     The government
    concedes that this metaphor was inconsistent with the specific-
    intent element of a RICO conspiracy offense and, thus, improper.
    Given this concession, we are left to determine whether the
    - 119 -
    impropriety was harmless.      For that purpose, "[t]he bottom-line
    question is whether the impropriety 'so poisoned the well that the
    trial's outcome was likely affected.'"               Kuljko, 1 F.4th at 94
    (quoting United States v. Mejia-Lozano, 
    829 F.2d 268
    , 274 (1st
    Cir. 1987)).
    "In    this   context,    harmless    error    review     takes   into
    account a multiplicity of factors."            
    Id.
        Those factors include
    "the severity of the impropriety, the nature of the impropriety
    (that is, whether or not it was deliberate, whether or not it was
    isolated, and the like), the strength of the government's case
    against the defendant, and how the district court responded to the
    impropriety (especially the timing, nature, and force of any
    curative instructions)."     
    Id.
        The district court, looking at the
    "loaded gun" metaphor through this prism, concluded that each of
    the pertinent factors "counsel[ed] against a finding that the
    Government's misstatement 'so poisoned the well' as to warrant a
    new trial."     Gurry, 427 F. Supp. 3d at 201.          We agree.
    This inquiry is, of course, case-specific. As we already
    have explained, see supra Parts III(A)-(D), the evidence of the
    defendants' guilt was copious. The unseemly metaphor itself played
    only a bit part in the case:       the prosecutor used it only once in
    a rebuttal that lasted around thirty minutes and in a trial that
    lasted for over seven weeks.       Importantly, the prosecutor made no
    attempt to weave the metaphor into other portions of either his
    - 120 -
    closing argument or the trial as a whole.             Considering that the
    "loaded gun" imagery occupies only a few lines in a compendious
    transcript, the infelicitous comment can fairly be described as
    "isolated."      United States v. Alcantara, 
    837 F.3d 102
    , 110 (1st
    Cir. 2016).
    The    defendants      disagree.       They   argue    that   the
    prosecutor's improper metaphor was a deliberate effort to portray
    them "as indiscriminate drug dealers."           In support, they rely on
    United States v. Carpenter, 
    494 F.3d 13
     (1st Cir. 2007) — a case
    in which the defendant was convicted of defrauding investors by
    misrepresenting his investment strategy, 
    id. at 16
    . The prosecutor
    used   "some   permutation     of   the   word   'gamble'"   in   "eighteen
    instances"     during   closing     argument,    as   well   as   "numerous
    references to other gambling terms" like "cashing in chips,"
    "doubling down," and "river boat gambler."               
    Id. at 23
    .      The
    district court granted the defendant a new trial, concluding that
    these persistent references reflected a deliberate (and ultimately
    successful) attempt to inflame the jury, and we affirmed.           See 
    id. at 22
    .
    Except, perhaps, to the extent that it illustrates the
    wide margins of the district court's discretion with respect to
    the granting of a new trial based on an out-of-bounds closing
    argument, Carpenter is not a fair congener.           That case involved a
    series of improper references and a pattern of abuse. In contrast,
    - 121 -
    the prosecutor in this case used the "loaded gun" metaphor once,
    and the district court supportably found that it was an isolated
    instance and not a continuing theme.            Moreover, the district court
    in    Carpenter     found    that    the    prosecutor's     misconduct       was
    prejudicial, whereas in this case the district court found that
    the   misconduct,    in     light   of   the    curative   instructions,      was
    harmless.    Given these significant discrepancies, comparing this
    case to Carpenter is like comparing cabbages to cantaloupes.
    Here,     moreover,      the       district    court's      curative
    instructions were carefully crafted and went to the heart of the
    matter.     The content and timing of those instructions                  argue
    persuasively against a finding that the government's misstatement
    irretrievably poisoned the well.               Importantly, the instructions
    unambiguously     debunked    the   prosecutor's      mistaken   view    of   the
    specific-intent element of the charged offense.               The prosecutor
    had told the jury that people intend the reasonably foreseeable
    consequences of their actions.           To ensure that the jurors did not
    get the wrong impression, the court told them that this proposition
    had nothing to do with the case at hand.              Furthermore, the court
    told them in no uncertain terms that "knowledge of foreseeable
    consequences without more is not enough to establish that someone
    specifically      intended      certain        conduct."      These     pointed
    instructions cleared the air and kept the jurors focused on the
    real issues in the case.
    - 122 -
    Grasping at straws, the defendants say that the curative
    instructions were insufficient because they failed to tell the
    jury that the prosecutor's argument was improper.      But a trial
    court is not required to use magic words in framing curative
    instructions:   it is only required to convey, in clear language,
    a message adequate to redress the perceived harm.       See United
    States v. Riccio, 
    529 F.3d 40
    , 45 (1st Cir. 2008) ("This court has
    repeatedly held that a strong, explicit and thorough curative
    instruction to disregard improper comments by the prosecutor is
    sufficient to cure any prejudice from prosecutorial misconduct.").
    The curative instructions given by the court below satisfied this
    standard, and the court — exercising its discretion — determined
    that adding a specific indictment of the prosecutor's misstatement
    was unnecessary.   The substantial deference that we afford trial
    courts in matters of this sort reflects an awareness that the
    "trial judge . . . listened to the tone of the argument as it was
    delivered," had an opportunity to "observe[] the apparent reaction
    of the jurors," and was "more conversant with the factors relevant
    to the determination."   Carpenter, 
    494 F.3d at 24
    .   We think that
    the district court's determination that its curative instructions
    would set the jury straight, without any need to place a scarlet
    letter on the prosecutor, was within the broad compass of its
    discretion.
    - 123 -
    One further observation should be made.         Although the
    district court's curative instructions are adequate on their face,
    the record also offers an external validation of their efficacy.
    As the district court noted, the "loaded gun" metaphor "related
    primarily" to the intent element of the CSA and honest-services
    predicates.       Gurry, 427 F. Supp. 3d at 199 n.94.       Thus, Gurry's
    acquittal on these two predicates lends considerable credence to
    the conclusion that the district court's curative instructions
    ensured that any damage done by the prosecutor's improper metaphor
    did not affect the outcome of the trial.          See Kuljko, 1 F.4th at
    95.
    We summarize succinctly.       In view of the isolated nature
    of the gun metaphor, the timely and effective curative instructions
    given by the district court, the government's independently strong
    case against the defendants, and the jury's acquittal of Gurry on
    the   CSA   and    honest-services    predicates,    we   hold   that   the
    prosecutor's comment, though unacceptable, was harmless.                See
    Kuljko, 1 F.4th at 95.
    XIV
    The penultimate leg of our odyssey brings us to the
    defendants' challenges to the district court's restitution orders.
    They argue that the district court's calculation of the restitution
    amounts reflected only "a kind of rough justice," unsupported by
    - 124 -
    the    record.      The    government   defends       the   district    court's
    calculations.
    We paint the backdrop. In the wake of the jury verdicts,
    the government sought $306,000,000 in restitution.               This figure
    reflected the value of all Subsys prescriptions written during the
    racketeering      period   (2012-2015).         The    defendants      objected,
    challenging the government's method of computation and asserting
    that the government's suggested price tag was exorbitant.                    The
    district court found a middle ground, ordering restitution in
    lesser amounts.       See United States v. Babich, No. 16-CR-10343,
    
    2020 WL 759380
    , at *6 (D. Mass. Feb. 14, 2020); see also supra
    note 3 (listing inter alia per-defendant restitution amounts).
    En route the court made five specific rulings.               First,
    the court awarded restitution to six patient victims.               See Babich,
    
    2020 WL 759380
    ,   at    *3-4.     Second,    the    court   declined     the
    government's invitation to base restitution on the totality of
    Subsys prescriptions written during the life of the conspiracy.
    See 
    id. at *6
    .      Even so, the court acknowledged that sifting the
    legitimate prescriptions from the fraudulent ones would "be too
    complicated and unduly prolong and burden the sentencing process."
    
    Id.
        With that in mind, the court made its third ruling, limiting
    restitution to losses traceable to prescriptions written solely by
    thirteen    bribed     coconspirator      doctors      identified       by   the
    government.      See 
    id.
    - 125 -
    Fourth, the court awarded as restitution 100 percent of
    the insurers' paid claims for Subsys prescriptions written by those
    thirteen coconspirator-prescribers.          See 
    id.
         In making these
    awards, the court refused to apply two reductions urged by the
    defendants.   See 
    id.
         One requested reduction was "to account for
    only those claims that passed through the IRC."              
    Id.
       The other
    was "to account for only those prescriptions made for non-cancer
    patients."    
    Id.
       Figures reported by the government for these two
    categories, the defendants argued, should be deemed a cap for
    permissible restitution.18        The district court rejected this two-
    pronged argument, stating that "[a]lthough the Court finds the
    amount of restitution owed beyond the thirteen co-conspirator
    doctors to be too complicated to calculate, it is clear that the
    amount that would be owed is at least equal to the total value of
    prescriptions written by the bribed doctors."          
    Id.
    Fifth,    the   court    apportioned   restitution.       It   held
    Kapoor fully responsible for the total amount of restitution owed
    — $59,755,362.45 — and capped the restitution obligations of the
    18 According to a government expert, "approximately 80.9% of
    all Subsys prescriptions" were processed by the IRC. And according
    to a second government expert, prescriptions written for non-
    cancer patients accounted for approximately 73 percent of Subsys
    prescriptions written by the thirteen coconspirator-prescribers.
    - 126 -
    other defendants at lesser levels.19             See Babich, 
    2020 WL 1235536
    ,
    at *10.
    The central restitution-related issue on appeal revolves
    around the district court's decision to award insurers 100 percent
    of paid claims for Subsys prescriptions written by the thirteen
    coconspirator-prescribers.           "We review restitution          orders for
    abuse of discretion, examining the court's subsidiary factual
    findings    for    clear   error    and   its    answers    to   abstract   legal
    questions de novo."        United States v. Chiaradio, 
    684 F.3d 265
    , 283
    (1st Cir. 2012); see Padilla-Galarza, 990 F.3d at 92.
    A     defendant     convicted       of   certain     federal    crimes
    (including,     as   relevant    here,     crimes    "committed    by   fraud   or
    deceit," 18 U.S.C. § 3663A(c)(1)(A)(ii), "must make restitution to
    victims commensurate with the victims' actual losses," United
    States     v.   Naphaeng,     
    906 F.3d 173
    ,     179   (1st    Cir.    2018).
    "[R]estitution is designed to compensate the victim, not to punish
    the offender."       
    Id.
       In awarding restitution, the court's goal is
    "to make the victim whole again."           United States v. Innarelli, 
    524 F.3d 286
    , 293 (1st Cir. 2008).            Thus, a restitution order should
    19Of course, liability for restitution under federal law may
    be joint and several and may be apportioned by the court among the
    responsible parties. See 
    18 U.S.C. § 3664
    (h). In this instance,
    the court apportioned that liability among the defendants who went
    to trial and those that pleaded guilty before trial (Burlakoff and
    Babich).
    - 127 -
    "not confer a windfall upon [the] victim."     Naphaeng, 906 F.3d at
    179.
    For the purpose of calculating restitution, actual loss
    is the beacon by which federal courts must steer.         See id.     In
    this context, actual loss is "limited to [the] pecuniary harm that
    would not have occurred but for the defendant's criminal activity."
    Id. (quoting United States v. Alphas, 
    785 F.3d 775
    , 786 (1st Cir.
    2015)).   This standard obligates the government to show both that
    the particular loss would not have occurred but for the conduct
    undergirding the offense of conviction and that a causal nexus
    exists between the loss and the conduct — a nexus that is neither
    too remote factually nor too remote temporally.      See United States
    v. Cutter, 
    313 F.3d 1
    , 7 (1st Cir. 2002).
    Restitution   is   serious    business,   but   hearings   to
    quantify restitution amounts should not be allowed to spawn mini-
    trials.   As we previously have explained, we do not expect a
    sentencing court to "undertake a full-blown trial" in order to
    arrive at an appropriate restitution amount.        Naphaeng, 906 F.3d
    at 179.    Nor do we hold a sentencing court to a standard of
    "absolute precision" when fashioning restitution orders.             Id.
    (quoting United States v. Mahone, 
    453 F.3d 68
    , 74 (1st Cir. 2006));
    see United States v. Sánchez-Maldonado, 
    737 F.3d 826
    , 828 (1st
    Cir. 2013).    In the end, we will uphold a sentencing court's
    restitution award "[a]s long as the court's order reasonably
    - 128 -
    responds to some reliable evidence."         Sánchez-Maldonado, 737 F.3d
    at 828; see Naphaeng, 906 F.3d at 179 ("[A] restitution award
    requires only 'a modicum of reliable evidence.'" (quoting United
    States v. Vaknin, 
    112 F.3d 579
    , 587 (1st Cir. 1997))).
    Although    this    standard    is        "relatively   modest   in
    application," Padilla-Galarza, 
    990 F.3d 60
     at 92, it has some
    teeth.   A sentencing court's "[m]ere guesswork will not suffice."
    Naphaeng, 906 F.3d at 179; see Vaknin, 
    112 F.3d at 587
    .             Similarly,
    "rough      approximation[s]"       that         do      not    "sufficiently
    reflect[] . . . the losses" of the victims are not appropriate
    grist for the restitution mill.       Innarelli, 
    524 F.3d at 294
    .            The
    court must resolve any genuine and material disputes about "the
    fact, cause, or amount of the loss" by a preponderance of the
    evidence.    Vaknin, 
    112 F.3d at 582-83
    ; see 
    18 U.S.C. § 3664
    (d).
    Given this framework, we conclude that the district
    court's determination to award as restitution 100 percent of Subsys
    claims   linked   to     the   thirteen    coconspirator-prescribers          is
    insupportable.    To be specific, the court's determination that all
    of the claims traceable to the thirteen coconspirator-prescribers
    constituted actual losses caused by the defendants' fraudulent
    conduct was not borne out by the preponderance of the evidence.
    For one thing, no party offered evidence that supported the 100-
    percent figure.        In fact, a government expert opined, without
    contradiction, that "approximately 80.9% percent of all Subsys
    - 129 -
    prescriptions passed through the IRC."            80.9 percent is not 100
    percent, and the government represented to the court that the
    expert's figure was "a fair and consistent, reasonable approach
    for the court to use."          According this figure due weight, it is
    evident that the government did not establish but-for causation
    for all of the claims traceable to the thirteen coconspirator-
    prescribers.     Indeed, the government's steadfast reliance on the
    expert's calculations is functionally equivalent to an admission
    that   not   every    Subsys    prescription    written   by   these   doctors
    received prior authorization as a result of IRC fraud.
    For another thing, the district court appears to have
    taken a shortcut to compensate for the difficulty of calculating
    restitution    with    respect    to   Subsys   prescriptions    written    by
    unbribed physicians.           See Babich, 
    2020 WL 759380
    , at *6.          In
    justifying     its    finding     of   actual    loss     generated    through
    coconspirator-prescribers, the district court pointedly referred
    to the incalculable losses caused by non-bribed doctors.               See 
    id.
    This reference, though, was out of step with the court's earlier
    determination that restitution would take account only of the
    losses caused by the coconspirator-prescribers.             See 
    id.
        To this
    extent, then, the court's award was internally inconsistent:                on
    the one hand, the court appears to have found that the losses
    generated by non-bribed doctors were incalculable but, on the other
    - 130 -
    hand, to have found that those losses nonetheless justified more
    munificent restitution awards.
    These infirmities doom the restitution orders.             Every
    loss that factors into the restitutionary amount must "have an
    adequate   causal   link   to   the   defendant[s']    criminal    conduct."
    Alphas, 785 F.3d at 786.        The blending of two distinct sets of
    losses, one of which was         incalculable,      fails to satisfy the
    causality requirement.      Consequently, the challenged restitution
    orders must be vacated.         On remand, the district court should
    recalculate the amounts of restitution consistent with its earlier
    determination that restitution should be limited to prescriptions
    written by the coconspirator-prescribers.          What remains is for the
    court to "tak[e] into account the extent (if at all) to which the
    [coconspirator-prescribers']          claims     encompassed      legitimate
    losses" not processed through the IRC, id., and to refashion the
    restitution orders accordingly.            Although the court's "reasoning
    and the calculations leading to the amounts ordered" must be clear,
    Innarelli, 
    524 F.3d at 295
    , its bottom-line determination need
    only amount to a reasonable response to reliable evidence in the
    record, see Sánchez-Maldonado, 737 F.3d at 828.
    XV
    The finish line is in sight.         The district court ordered
    monetary forfeitures in varying amounts, see supra note 3, and the
    affected parties (including the government) ask us to resolve
    - 131 -
    dueling claims of error pertaining to these forfeiture orders.         In
    evaluating    forfeiture   orders,    we   assay    the   court's   legal
    conclusions de novo and examine its factual findings for clear
    error.    See United States v. George, 
    886 F.3d 31
    , 39 (1st Cir.
    2018).
    The baseline rule is uncontroversial.          A defendant who
    has been convicted of RICO conspiracy is liable to forfeit "any
    property constituting, or derived from, any proceeds which the
    person    obtained,   directly   or   indirectly,    from    racketeering
    activity."    
    18 U.S.C. § 1963
    (a)(3).       Following the defendants'
    convictions, the government sought forfeitures equaling the gross
    proceeds obtained by Lee, Simon, Gurry, and Rowan, respectively,
    during the racketeering period. Ruling that "any proceeds obtained
    from Insys during the time of the conspiracy are forfeitable," the
    district court obliged.    Babich, 
    2020 WL 1235536
    , at *5.      The court
    went on to hold that "the Defendants' salaries and exercised stock
    options constitute 'proceeds' that were obtained 'directly or
    indirectly' from the RICO conspiracy."20 
    Id.
     As an offset, though,
    the court held that the income taxes that each defendant had paid
    were not "proceeds" under section 1963(a)(3) because those amounts
    never "ended up in the Defendants' pockets for them to spend in
    20 Insofar as the forfeiture orders are based upon               the
    monetization of exercised stock options, neither side                 has
    challenged the district court's calculations.
    - 132 -
    the way in which they wanted."      
    Id. at *7
     (alterations omitted).
    Accordingly, the court — in shaping its forfeiture orders as to
    Lee, Simon, Gurry, and Rowan — deducted from their respective gross
    incomes "the amount of the tax withheld" during the racketeering
    period.   
    Id.
    Gurry lands the first blow.          He   contends that the
    district court erred as a matter of law because "it declined to
    determine what portion of [his] income was tainted by racketeering
    activity."    The government counterpunches.    In a cross-appeal, it
    contends that the tax offsets were erroneous as a matter of law.21
    We deal with each contention in turn.
    A
    A defendant's proceeds from racketeering activity are
    "subject to a rule of proportionality."        Cadden, 965 F.3d at 37
    (quoting United States v. Angiulo, 
    897 F.2d 1169
    , 1211 (1st Cir.
    1990)).      This guardrail ensures that proceeds are subject to
    forfeiture only to "the extent they are tainted by the racketeering
    activity."      
    Id.
     (quoting Angiulo, 
    897 F.2d at 1212
    ).   It follows
    that a district court's forfeiture order must determine "the
    portion of [the defendant's] earnings . . . over the relevant time
    21 Due to his unique compensation package, Kapoor neither
    sought nor received a tax offset. See Babich, 
    2020 WL 1235536
    , at
    *6 n.6.    As a result, the government's cross-appeal does not
    implicate his forfeiture order.
    - 133 -
    period that were tainted by the racketeering activity and therefore
    subject to forfeiture."        
    Id. at 38
    .
    Gurry   advances    three    arguments   as   to   why   certain
    portions of his work at Insys cannot be linked to the racketeering
    activity and as to why, as a result, the forfeiture of his entire
    salary was in error.      Lee, Simon, and Rowan adopt these arguments.
    Gurry first notes that although he was an Insys employee
    until 2016, his work at the IRC ended in May of 2014.                Because
    "[t]here is no evidence that his job responsibilities after May
    2014     included   any   racketeering      activity,"    he   posits,   any
    subsequent proceeds are not subject to forfeiture.             This is too
    crabbed a view of the facts:             Gurry's relinquishment of the
    responsibility for supervising the IRC did not end his furtherance
    of, participation in, and profiting from the racketeering scheme.
    By 2014, Gurry had negotiated with insurance companies to add
    Subsys to their compendia of approved drugs.         Those efforts helped
    the IRC to continue its fraudulent scheme and garner additional
    revenue for Insys even after Gurry's responsibilities changed.            To
    the extent that Gurry's racketeering activities on behalf of the
    IRC generated profits for him after his departure from the IRC,
    that revenue constitutes proceeds "obtained from the racketeering
    activity . . . that formed the basis of [his] convictions."              
    Id. at 37
    .    Those proceeds were, therefore, forfeitable.         See 
    id.
       And
    in any event, "[m]ere cessation of activity in furtherance of the
    - 134 -
    conspiracy does not constitute withdrawal" from the conspiracy.
    United States v. Leoner-Aguirre, 
    939 F.3d 310
    , 319 (1st Cir. 2019)
    (quoting United States v. Ciresi, 
    697 F.3d 19
    , 27 (1st Cir. 2012)).
    Next, Gurry maintains that his work for the IRC comprised
    only 20 percent of his job responsibilities.       But he cites no
    authority to support a reduction in his forfeiture amount based on
    the percentage of his time devoted to the scheme.       It would be
    perverse to provide an incentive for racketeering efficiency, and
    we do not think that a racketeer can limit his forfeiture liability
    by the simple expedient of devoting some of his time to legitimate
    work.     Forfeiture calculations depend on the proceeds gained
    directly or indirectly from racketeering activity, see 
    18 U.S.C. § 1963
    (a)(3), not on the percentage of a defendant's time devoted
    to the conspiracy.22
    Gurry also contends that his forfeiture order should
    reflect only the percentage of fraudulent Subsys sales during the
    racketeering period, not all Subsys sales during that period.   The
    government confesses error and agrees that a remand on this ground
    is appropriate.   That confession is premised upon our opinion in
    22 At any rate, Gurry has not established whether the 80
    percent of his work allegedly unrelated to the racketeering
    activity generated earnings for him that were independent of
    fraudulent Subsys sales. What counts is that the record supports
    the conclusion that Gurry knowingly joined and furthered the
    insurance-fraud scheme and that his earnings during that time for
    the "non-IRC work" flowed at least indirectly from his IRC efforts.
    - 135 -
    Cadden, 965 F.3d at 37-38, which was decided while these appeals
    were pending.    There, we vacated a forfeiture order because "the
    government failed to prove that all [drug] sales over the period
    in question were generated by fraud."            Id.    Profits from non-
    fraudulent sales, we said, are not proceeds obtained (directly or
    indirectly) from the racketeering activity.            See id.       at 37-38.
    We ordered the district court, on remand, "to assess . . . the
    portion of [the defendant's] earnings . . . that were tainted by
    racketeering activity."       Id. at 38.
    The same instruction is warranted here.            As a matter of
    law, any Subsys prescription processed independently of the IRC
    falls outside the scope of the fraudulent scheme.             And since the
    IRC did not seek prior authorization for every Subsys prescription,
    the district court must determine the percentage of Subsys prior
    authorizations that were successful through the IRC's efforts.
    Forfeiture of the whole of Gurry's earnings was, therefore, in
    error.   The forfeiture orders pertaining to Lee, Simon, and Rowan
    suffer   from   the   same   defect,   and   those   orders   also    must   be
    revisited.
    Gurry is barking up the wrong tree, however, when he
    tries to convince us that "the IRC did not lie about every
    prescription it processed."       The defendants agreed below that 73
    percent of the IRC's authorizations involved prescriptions for
    non-cancer patients and the district court found that the IRC
    - 136 -
    "misled insurers in a number of ways," even when the patients had
    cancer.     Babich, 
    2020 WL 1235536
    , at *6.            The IRC's deceptions
    included    dissembling     about     patients   experiencing     breakthrough
    cancer pain, having a history of cancer, having tried-and-failed
    other medications, and having difficulty swallowing.                    See 
    id.
    These tactics were systematically employed by the IRC and did not
    become honest or accurate by virtue of a patient having cancer.
    See 
    id.
         Mendacity was a hallmark of the IRC's operations — a
    hallmark that permeated its prior authorization efforts.
    We agree with the district court that "the fact that a
    prescription was requested for a cancer patient is insufficient to
    establish    that   it    was   not   fraudulent."     
    Id.
          Based   on   the
    overwhelming evidence that these sleazy tactics were business as
    usual at the IRC, we find that the district court's determination
    that each prescription processed by the IRC during the racketeering
    period was tainted by fraud is grounded upon reasonable inferences
    drawn from adequately established facts.              The district court's
    determination was not clearly erroneous.
    B
    We turn next to the government's cross-appeal.                    We
    conclude    that    the   district     court's   decision    to   offset     the
    defendants' forfeiture obligations based on the income taxes they
    paid on those earnings constituted error.            Two recent cases inform
    this conclusion.
    - 137 -
    In Cadden, the defendant argued that "the District Court
    erred in calculating the forfeiture amount without deducting the
    amount in taxes that he paid on those proceeds."                 965 F.3d at 38.
    We disagreed, holding that "the word 'proceeds' in the forfeiture
    statute refers to gross proceeds, not net profits."                 Id. (quoting
    United States v. Hurley, 
    63 F.3d 1
    , 21 (1st Cir. 1995)).                 Because
    the defendant "clearly 'obtained' the amount of funds subject to
    forfeiture before they were subject to taxation," that amount was
    "subject to forfeiture, even though the amount he obtained was
    itself taxable."     
    Id.
    Our decision in United States v. Chin, 
    965 F.3d 41
     (1st
    Cir. 2020), is to like effect.         There, we concluded that "the fact
    that the offender is required to pay a certain portion of his
    salary to the federal government as taxes does not affect the fact
    that he 'obtained' that portion," 
    id. at 57
    .                 Taken together,
    Cadden and Chin resolve the issue.              The defendants in this case
    were taxed on the proceeds subject to forfeiture precisely because
    they had "obtained" those proceeds.
    C
    Consistent with these rulings, we vacate the district
    court's forfeiture orders as to Lee, Simon, Gurry, and Rowan.                  The
    district   court    must    assess    what     percentage   of     Subsys   prior
    authorizations     were    successful       independently   of    the   IRC,   and
    reduce the forfeiture amounts of each defendant by that percentage.
    - 138 -
    See Cadden, 965 F.3d at 38.              It should not, however, apply any tax
    offset.          We   remand     for   the     purpose    of   recalculating     these
    forfeiture amounts.
    XVI
    We need go no further.23               Insys and Kapoor deserve great
    credit for developing Subsys — a medication which, appropriately
    dispensed,       would    have    been    an    important      weapon   in   society's
    continuing battle to alleviate breakthrough cancer pain.                           But
    Subsys was not appropriately dispensed.                    Instead, the defendants
    — driven by unalloyed greed — marketed the medication through a
    pattern of racketeering activity and conspired to ensure that it
    would be dispensed outside the usual course of medical practice
    and without a legitimate medical purpose. "Pill mills for us meant
    dollar signs" and — from the defendants' coign of vantage — Subsys
    prescriptions, like snake oil on the frontier, became above all
    else a means of generating revenue.                       In taking this cynical
    approach, the defendants turned what should have been a blessing
    into a curse.
    The jury, after a protracted trial presided over with
    great     care    and    circumspection        by    a   no-nonsense    judge,   heard
    23To the extent, if at all, that particular defendants have
    alluded to other potential claims of error in their extensive
    briefing, those claims are either insufficiently developed or
    patently meritless.    Thus, we reject them without further
    elaboration.
    - 139 -
    detailed   evidence   with   respect   to    the   defendants'     pernicious
    practices regarding the marketing of Subsys.             The jury found the
    evidence   sufficient   to   hold   the     defendants    guilty    beyond    a
    reasonable doubt on virtually all of the charges lodged in the
    indictment.   The jury's findings and verdicts are, we think, fully
    supportable, and the defendants' multifaceted challenges to them,
    though skillfully presented, are without force.               We conclude,
    therefore, that the findings and verdicts must stand.
    We reach a different result with respect to certain
    monetary awards made by the district court ancillary to sentencing.
    Although the defendants do not challenge their sentences as such
    (and those sentences must remain intact), the restitution and
    forfeiture orders are attacked (some by the defendants, some by
    the government, and some by both).          We find that the challenged
    amounts were not properly calculated in certain respects.              Thus,
    certain restitution and forfeiture orders, identified above, must
    be vacated, and the case must be remanded for further proceedings
    consistent with this opinion.
    To summarize, we set aside the district court's vacation
    of certain of the jury's special findings regarding the guilt of
    Kapoor, Lee, Simon, and Rowan vis-à-vis the CSA and honest-services
    predicates and order reinstatement of those findings.              We affirm
    the jury's special findings and verdicts as to all defendants.               We
    also affirm the district court's denial of the defendants' sundry
    - 140 -
    motions for judgments of acquittal and/or new trials.               So, too, we
    affirm the district court's orders with respect to challenged
    pretrial and mid-trial rulings. Finally, we affirm the defendants'
    sentences,24    but     vacate   the    district   court's    restitution   and
    forfeiture     orders    (except   for    the    forfeiture   order   regarding
    Kapoor)   and     remand     for   recalculation       of     the   appropriate
    restitution and forfeiture amounts.
    Affirmed in part, reversed in part, vacated in part, and remanded.
    24The government has not requested that, upon reinstatement
    of the special findings concerning the CSA and honest-services
    predicate, see supra Part III, we remand for resentencing of the
    four affected defendants (Kapoor, Lee, Simon, and Rowan). In the
    absence of such a request, we see no need to do so.
