    BARRON, Chief Judge.   Rafael Pina-Nieves challenges his
    2021 convictions in the United States District Court for the
    District of Puerto Rico for, respectively, possessing firearms and
    ammunition as a felon in violation of 
    18 U.S.C. § 922
    (g)(1) and
    possessing a machinegun in violation of 
    18 U.S.C. § 922
    (o).      We
    affirm the former conviction but reverse the latter because it is
    not supported by sufficient evidence.
    I.
    In 2015, Pina-Nieves, a music producer and business
    owner, pleaded guilty in the District of Puerto Rico to one count
    of bank fraud, a felony, in violation of 
    18 U.S.C. §§ 1344
     and 2.
    That conviction made it a federal offense under § 922(g)(1) for
    Pina-Nieves to possess a firearm or ammunition.
    In 2020, the Federal Bureau of Investigation ("FBI"),
    while investigating a money-laundering operation, obtained a court
    order to wiretap phone lines at a gas station in Puerto Rico that
    Pina-Nieves owned.    Through the wiretap, the FBI intercepted a
    telephone call on February 6 of that year between Pina-Nieves and
    one of his employees, Joed Romero-Soler.       The call concerned
    renovating a house that Pina-Nieves owned in Caguas Real, a gated
    community in Caguas, Puerto Rico, so that the house could be rented
    or sold.
    - 3 -
    The following exchange occurred during the call, which
    took place in Spanish, according to the transcript that sets forth
    the official translation:
    Pina-Nieves: And what do we do with the safe,
    motherfucker?
    Romero-Soler: Bro, right. You have that there
    built-in.   A whole ordeal, right? No, man,
    leave it open.
    Pina-Nieves: Man, yes.
    Romero-Soler: You know, and take out whatever
    you have . . . and, if you have anything . . .
    and leave it open behind there so that whoever
    moves in there will use it. You know, tell
    Miguel to reset it. You know, that, look . . .
    Pina-Nieves: Nah, nah, bro, I have money and
    I have all sorts of things in there: my guns,
    rifles, bullets.
    Romero-Soler: Well, exactly, have Miguel take
    out anything he needs to take out. You know
    what you have in there, right?
    Pina-Nieves: Yes, but no, no . . . I'm not
    giving that motherfucker anything.
    Romero-Soler: Well, I don't know . . . and
    . . . and . . . you know, and the guns? Give
    them to Johnny.
    Pina-Nieves: No,   because   all   of   that   is
    [unregistered].
    Romero-Soler: Nah, I'll wait until you get
    here.   I mean, yes, yes, when you get here
    . . . I mean, it's alright.    Anyway. . . .
    Um, yes, when you come, well . . . you know,
    take out whatever you need to take out and all
    that and . . . and that's it.
    - 4 -
    Pina-Nieves: No, but the thing is I can't take
    it out either. That . . . well, yes. . . .
    The thing is I don't have . . . I would have
    to put . . . I would have to put a safe
    somewhere that's not . . . you know, here, in
    this house, it can't be done, because there's
    no space. This is really small.
    FBI agents executed a warrant to search the Caguas Real
    house on April 1, 2020.      The search revealed a hidden door and
    keypad behind a full-length, floor-to-ceiling mirror, estimated to
    be "eight to 10 feet" wide, in the master bedroom.          The door led
    to a hidden room that contained one Smith & Wesson pistol, one
    Glock   pistol,   multiple   boxes   of   ammunition,    various   firearm
    magazines, a bayonet, a holster, a satellite phone, and a safe
    holding more than $135,000 and €10,000 in cash and a certificate
    bearing Pina-Nieves's name.     The Glock pistol had been modified to
    fire fully automatically with a single pull of the trigger.
    A grand jury indicted Pina-Nieves in the District of
    Puerto Rico on August 13, 2020 on two counts.           Count One charged
    Pina-Nieves with violating 
    18 U.S.C. § 922
    (g)(1), which makes it
    "unlawful for any person . . . who has been convicted in any court
    of, a crime punishable by imprisonment for a term exceeding one
    year . . . to . . . possess in or affecting commerce, any firearm
    or ammunition."    Count Two charged him with violating 
    18 U.S.C. § 922
    (o), which makes it "unlawful for any person to transfer or
    possess a machinegun."       A "machinegun" under § 922(o) is "any
    - 5 -
    weapon which shoots, is designed to shoot, or can be readily
    restored to shoot, automatically more than one shot, without manual
    reloading, by a single function of the trigger."          United States v.
    Nieves-Castaño, 
    480 F.3d 597
    , 599 (1st Cir. 2007) (quoting 
    26 U.S.C. § 5845
    (b)).
    Pina-Nieves was convicted on both counts after a brief
    trial and sentenced to 41 months' imprisonment.                 This appeal
    followed.
    II.
    We start with Pina-Nieves's contention that his § 922(o)
    conviction   must   be   reversed    because   it   is   not   supported   by
    sufficient evidence.       To convict Pina-Nieves of the § 922(o)
    charge, the government was required to prove beyond a reasonable
    doubt that: (1) he knowingly possessed a machinegun on or about
    April 1, 2020; and (2) he had knowledge that the firearm had the
    characteristics that brought it within the statutory definition of
    a machinegun under § 922(o) (though not that he knew that those
    characteristics made the weapon a machinegun).             See Staples v.
    United States, 
    511 U.S. 600
    , 602 (1994); Nieves-Castaño, 480 F.3d
    at 599.
    Pina-Nieves's sufficiency challenge focuses solely on
    what the record shows regarding whether he knew the machinegun
    that he was convicted of possessing at the relevant time -- namely,
    the modified Glock pistol that the FBI agents found on April 1,
    - 6 -
    2020 in the hidden room of his Caguas Real house's master bedroom
    --   had   the    characteristics      that    made    it     a    machinegun     under
    § 922(o).        To succeed on this challenge, Pina-Nieves must show
    that no rational juror could find beyond a reasonable doubt that
    Pina-Nieves       knew   that   the    modified       Glock       pistol   had    those
    characteristics.         Jackson v. Virginia, 
    443 U.S. 307
    , 318 (1979)
    ("[T]he critical inquiry on review of the sufficiency of the
    evidence to support a criminal conviction must be not simply to
    determine    whether      the   jury   was     properly       instructed,        but   to
    determine whether the record evidence could reasonably support a
    finding of guilt beyond a reasonable doubt.").                     Our review is de
    novo, although we must review the evidence in the light most
    favorable to the verdict.        United States v. Kanodia, 
    943 F.3d 499
    ,
    505 (1st Cir. 2019).
    A.
    Pina-Nieves contends that the record shows that the
    evidence was not sufficient because the government failed to
    present any direct or circumstantial evidence that could support
    a reasonable inference that Pina-Nieves had "ever set eyes on the
    [modified Glock pistol], much less examined it or fired it."                           He
    notes, for example, that the government did not introduce evidence
    that his fingerprints were found on the gun.                       He adds that the
    record contains no evidence that he was the one who purchased the
    gun, which the record shows was bought in 2016 in Ohio.                     He notes,
    - 7 -
    too, that the record contains no evidence to indicate that the gun
    had been modified to make it a machinegun at the time that it was
    purchased.
    Pina-Nieves goes on to contend that these features of
    the record take on particular significance due to the absence of
    any evidence that, although Pina-Nieves owned the Caguas Real house
    "on or about April 1, 2020," he lived at that residence during
    that time.   Indeed, he notes, there is substantial evidence to
    show that he was living at that time either elsewhere in Puerto
    Rico or in Florida, as well as evidence that others had access to
    both the house and the area where the gun in question was found
    during the search on April 1, 2020.        Moreover, Pina-Nieves points
    out, there is no direct evidence in the record of his having been
    present in the Caguas Real house at any time after the Glock pistol
    was purchased in Ohio in 2016.
    Pina-Nieves   winds   up   his    sufficiency   challenge   by
    emphasizing that there is no evidence in the record -- direct or
    circumstantial -- as to when, from the time of the weapon's
    purchase in Ohio in 2016 to its discovery in his Caguas Real house
    on April 1, 2020, it had been modified to be a machinegun.            In
    consequence, although Pina-Nieves does not dispute that the gun in
    question is a machinegun under § 922(o) or that it was found in
    his Caguas Real house on April 1, 2020, he contends that, given
    that there is no evidence to indicate that he was at that house on
    - 8 -
    that date, the mere presence of that gun in that house on that
    date cannot suffice to permit the reasonable inference that he
    knew that the gun had the characteristics of being able to fire
    automatically.
    B.
    To   counter     Pina-Nieves's   argument,     the   government
    emphasizes that it may make its case about his knowledge of the
    characteristics of the weapon in question based on circumstantial
    evidence.    See United States v. Ridolfi, 
    768 F.3d 57
    , 61 (1st Cir.
    2014).     It then contends that the record suffices to show that
    Pina-Nieves constructively possessed the firearms found in his
    Caguas Real house on April 1, 2020, that one of those guns was a
    modified    Glock   pistol    that   qualifies   as   a   machinegun   under
    § 922(o), that the external modification that made the Glock pistol
    fully automatic was visible, that Pina-Nieves was acquainted with
    a range of weapons and firearms, and that the machinegun in
    question was found not just in a house that Pina-Nieves owned but
    in a hidden room attached to the master bedroom in that house.
    Moreover, the government points to what Pina-Nieves was
    heard saying during the intercepted February 6 call.              Here the
    government notes that, in addition to what Pina-Nieves concedes in
    his briefing to us was his reference to "pistols" during that call,
    the transcript of the phone call shows that he referred on it to
    "my guns" being "unregistered."         The government contends that the
    - 9 -
    description   of   the   guns    being     "unregistered"   is   significant
    because machineguns cannot be registered under federal law.             Thus,
    the government argues, that description provides support for the
    inference, when the evidence is considered as a whole,                      that
    Pina-Nieves knew that one of the guns to which he was referring at
    that time had the characteristics of a machinegun.
    C.
    The evidence certainly suffices to tie Pina-Nieves to
    the modified Glock pistol found in his house on April 1, 2020.               In
    fact, Pina-Nieves does not dispute on appeal that the evidence
    suffices to show that he was in constructive possession of that
    firearm as of that date.        But, we have made clear that a juror may
    not reasonably infer merely from the fact that one constructively
    possesses a machinegun that the defendant knows what he must under
    § 922(o)   about   the    characteristics       of   that    weapon.        See
    Nieves-Castaño, 480 F.3d at 599-600.
    Moreover,     although    Pina-Nieves     does   concede    in   his
    briefing to us that he referred on the February 6, 2020 call to
    "pistols," this limited description of those weapons is not direct
    evidence that he knew that either weapon had the characteristics
    of a machinegun.    In addition, his reference on that call to "my
    guns" being "unregistered" fails to assist the government in
    fending off the sufficiency challenge, because his prior felony
    conviction equally could explain why he could not register a
    - 10 -
    firearm.   Indeed, we note that the April 1, 2020 search that turned
    up the modified Glock pistol at Pina-Nieves's Caguas Real house
    discovered two pistols, not one, and yet only one of them qualified
    as a machinegun under § 922(o).
    Of course, we cannot look at each piece of evidence in
    isolation.   United States v. Ortiz, 
    966 F.2d 707
    , 711 (1st Cir.
    1992).   But, even when we consider the evidence as a whole, we are
    persuaded by Pina-Nieves's argument that the government's theory
    of   sufficiency    impermissibly       depends    either    on    speculative
    inferential leaps or the stacking of inference upon inference.
    See United States v. Guzman-Ortiz, 
    975 F.3d 43
    , 52-56 (1st Cir.
    2020).
    To conclude that Pina-Nieves not only was in possession
    of a machinegun "on or about April 1, 2020" but also knew that the
    machinegun could fire fully automatically, a juror would have to
    infer that Pina-Nieves had either seen it for long enough to become
    familiar with the characteristics of it that made it a machinegun
    or had been told at some point that it had those characteristics
    even though he had never seen it.
    But, as we have explained, there is no evidence in the
    record that shows when the Glock pistol was modified, reports
    anyone   having    told   Pina-Nieves    that     the   weapon    had    been   so
    modified, or places Pina-Nieves at his Caguas Real house at any
    time after the Glock pistol's 2016 purchase in Ohio.                    Moreover,
    - 11 -
    there is evidence that he was living elsewhere from at least 2010
    on, as well as evidence that others were in the house during that
    time with access to the area where the gun was found.   Thus, while
    Pina-Nieves does not dispute that the evidence suffices to show
    that he constructively possessed the weapon within the relevant
    time frame and that it was found in a house that he owned during
    that same time frame, we do not see how a rational juror could
    make the requisite inference that Pina-Nieves knew that this weapon
    had the characteristics of a machinegun other than by engaging in
    just the kind of speculation or inference-stacking that cannot
    suffice to support a conviction.
    D.
    The government does contend that our precedent requires
    that we conclude otherwise by pointing to our decisions in United
    States v. Laureano-Pérez, 
    797 F.3d 45
     (1st Cir. 2015), United
    States v. Shaw, 
    670 F.3d 360
     (1st Cir. 2012), and United States v.
    Giambro, 
    544 F.3d 26
     (1st Cir. 2008).   But, we do not agree.
    In Shaw, the government presented evidence that the
    defendant had recently handled the gun in question.     
    670 F.3d at 364
     (the defendant fired the modified gun and "deftly" unloaded
    it).   And, in Giambro, the government presented evidence that the
    defendant had seen the gun and was therefore familiar with the
    obvious "external indications signaling the nature of the weapon."
    - 12 -
    
    544 F.3d at 30-31
     (quoting Nieves-Castaño, 480 F.3d at 601). There
    is no such evidence in the record here.
    Moreover, the record in Laureano-Pérez also is not like
    the record here.                   In that case, one of the defendants, Jeffrey
    Cummings-Ávila, argued that the evidence did not suffice to support
    his § 922(o) conviction because the evidence did not suffice to
    establish beyond a reasonable doubt that he knew that the pistols
    that had been found in a closed red and black bag during a search
    of his apartment had the characteristics of a machinegun -- even
    though the evidence did suffice to show that each of the pistols
    found        in     that      bag     did        have    those     characteristics.             See
    Laureano-Pérez, 
    797 F.3d at 74
    .                         The defendant contended that was
    so    because               "the     government          provided        no     evidence       that
    [Cummings-Ávila] opened up the bag or was told what the bag
    contained."             
    Id. at 75
    .
    We     held,       however,       that    "the     cumulation"         of    four
    different strands of "circumstantial evidence" present in the
    record in that case was "just enough to sustain" the conviction.
    
    Id. at 76
    .             First, we pointed to the evidence that Cummings-Ávila
    "often stored guns and drugs" for a large, armed drug organization.
    
    Id. at 75
    .         Second,       we     explained       that       the   evidence    of
    Cummings-Ávila's role in the organization indicated that he was
    "trusted           by       his     co-conspirators,"            which        mattered    because
    "positions             of    trust     often       come     with     increased       access     to
    - 13 -
    information."       
    Id.
          Third,      we   pointed       to   the   evidence   that
    Cummings-Ávila was "close" to the organization's leader, as we
    concluded that a rational juror could conclude from this evidence
    of   their   closeness      that   the    leader       "would    have    confided   in
    [Cummings-Ávila] regarding the details of the bag" that was found
    in his apartment that contained the machineguns.                        
    Id. at 75-76
    .
    Finally,     we   pointed    to    testimony      of    a    witness     having   seen
    Cummings-Ávila firing .40- or .45-caliber pistols that had been
    modified to fire automatically shortly before Cummings-Ávila was
    given the bag in question.          
    Id. at 74, 76
    .
    There is no circumstantial evidence of the requisite
    knowledge in the record before us here that is like the evidence
    that we held was sufficient in Laureano-Pérez, a case that we
    deemed to be "close," 
    id. at 75
    .              For example, there is no witness
    testimony that Pina-Nieves had at any time (let alone in close
    proximity to the period from February 6, 2020 to April 1, 2020)
    handled a pistol that had been modified to be a machinegun or
    learned that a weapon that was his had been so modified.                    Moreover,
    there is no evidence that Pina-Nieves often stored guns for a
    criminal organization, much less evidence that he was sufficiently
    close to the leader of such an organization that he would have
    been informed of the details of the weapons he stored.
    And, while the record shows a machinegun was found in a
    house Pina-Nieves owned, no evidence places him in that house at
    - 14 -
    a time when the machinegun was known to have been in its modified
    state.     In fact, as we have noted, substantial evidence indicates
    that Pina-Nieves was not living there in the years leading up to
    the weapon's discovery in that house and that others had access to
    it in full.
    Our conclusion that the evidence is not sufficient also
    aligns with the out-of-circuit precedent that the defendant cites.
    See United States v. Rogers, 
    94 F.3d 1519
    , 1521-23 (11th Cir. 1996)
    (reversing the defendant's § 922(o) conviction                    "[b]ecause the
    Government     did   not     introduce   any    evidence     showing    that    [the
    defendant] was aware that [the modified pistol in question] had
    been altered to operate as a fully automatic weapon," even though
    the pistol was discovered in a black bag beneath the driver's side
    seat of the defendant's truck, the defendant had been driving the
    truck at the time, the defendant "correctly identified" the pistol
    during an interview with a special agent from the Bureau of
    Alcohol,      Tobacco,       and   Firearms,    and    the   pistol     had     been
    manufactured as a semi-automatic weapon); United States v. Michel,
    
    446 F.3d 1122
    , 1130-32 (10th Cir. 2006) (reversing the defendant's
    conviction for possession of an unregistered sawed-off firearm
    that   also    lacked    a    serial   number   in    violation    of   
    26 U.S.C. § 5861
    (d) and 5861(i) because "the government presented absolutely
    no evidence that [the defendant] ever observed or handled" the gun
    in question and thus could not support the "inferential leap"
    - 15 -
    required for the jury to find that he had knowledge of the gun's
    characteristics).
    In fact, the government does not attempt to address
    Rogers and contends that Michel's reasoning has no application to
    this case for reasons that we find unpersuasive.                  The government
    contends that Michel has little bearing here because it establishes
    merely that a "fleeting encounter was not enough to establish the
    defendant's familiarity with the gun and its characteristics."
    But,    Michel    focused   on   the    brief     nature   of    the   defendant's
    encounter with the weapon there to explain why there was not
    sufficient evidence to prove beyond a reasonable doubt that the
    defendant was familiar with the characteristics of that weapon
    that made it a sawed-off firearm.               See Michel, 
    446 F.3d at
    1130-
    32.     And here, given all the evidentiary gaps that we have
    described, a juror could no more reasonably infer from the nature
    of Pina-Nieves's tie to the weapon in question that it was beyond
    a reasonable doubt that he had seen the modifications that had
    transformed it into a machinegun than a juror could have in Michel.
    E.
    In sum, even though the government has sufficiently
    proved Pina-Nieves's constructive possession of the modified Glock
    pistol on or about April 1, 2020, based on the circumstantial
    evidence that is in the record, the government was required to
    prove   more     to   secure   this    conviction.         And   Pina-Nieves   has
    - 16 -
    persuasively made the case that the government failed to do so
    because it failed to identify any evidence in the record that could
    support a finding beyond a reasonable doubt that he knew as of the
    relevant time that the modified Glock pistol found had been so
    modified.   See Nieves-Castaño, 480 F.3d at 602.   Thus, we conclude
    that Pina-Nieves's § 922(o) conviction must be reversed.
    III.
    Pina-Nieves separately contends that both his § 922(o)
    conviction and his § 922(g)(1) conviction must be vacated due to
    trial errors.     The first claimed error concerns the District
    Court's decision to admit certain evidence pursuant to Federal
    Rule of Evidence 801(d)(2)(C) and (D).    The second claimed error
    concerns the District Court's decision to exclude certain evidence
    on relevancy grounds pursuant to Federal Rule of Evidence 401.
    We need not address Pina-Nieves's contention that his
    § 922(o) conviction must be vacated due to these asserted trial
    errors because it must be reversed on sufficiency grounds.    We do,
    however, need to address his contention that these claimed trial
    errors require that we vacate his § 922(g)(1) conviction.        Our
    review is for abuse of discretion because Pina-Nieves asserted
    each error below. See United States v. Velazquez-Fontanez, 
    6 F.4th 205
    , 219 (1st Cir. 2021).   But, although we are persuaded that the
    District Court did make the two asserted errors, they do not
    require that we overturn the conviction because we agree with the
    - 17 -
    government that the errors were harmless as to that conviction.
    See United States v. Piper, 
    298 F.3d 47
    , 56 (1st Cir. 2002).                 And
    that is so, we add, even if we were to consider their cumulative
    effect.
    A.
    We begin with the claimed error that implicates Rule
    801.   We will first set forth the relevant facts.                 We will then
    explain why we conclude that there was error.
    1.
    Three days before the first day of trial, Pina-Nieves
    filed a motion to dismiss the indictment.                 Pina-Nieves's trial
    counsel, Francisco Rebollo-Casalduc, signed and filed the motion.
    The   motion     argued   that     the   government   had    violated
    Pina-Nieves's Sixth Amendment right to counsel by engaging in
    prosecutorial misconduct, including by placing an informant in the
    defense camp who reported to the government "the content and
    substance    of     the     confidential       communications      between   Mr.
    Pina-Nieves and his attorneys."              The motion further argued that
    the    information        reported    included       Pina-Nieves's      "personal
    evaluation of plea offers and counter offers and [Pina-Nieves's]
    thoughts on potential defense trial strategies."                And, the motion
    contended,    the     government's       alleged      misconduct     prejudiced
    Pina-Nieves because the information that the government received
    - 18 -
    had caused federal prosecutors to harden their plea-bargaining
    position such that the "bottom line . . . involved time in prison."
    At one point, the motion stated the following:
    As Exhibit 1 reflects, on October 2, 2020, the
    government informant, whose name is blacked
    out in the report, informed case agent Justin
    Turner that "Pina had a meeting with his
    attorneys, after having received evidence form
    [sic] the U.S. Attorney's Office associated
    with his pending charges and trial.        As a
    result,   Pina   gathered    his   family   and
    associates on his new yacht to discuss the
    case. Pina was advised by his attorneys he
    will most likely have to spend time in prison,
    as a result of the charges. Pina's attorneys
    will reach out to the U.S. Attorney's Office
    in the near future to broker a plea agreement.
    During the meeting on the yacht, Pina prepared
    his family and associates for the likelihood
    of his serving time in prison and handed down
    his responsibilities to his associates on how
    to run the business in his absence." Just the
    fact that the government learned that the
    defendant was resigned to the fact that he
    would have to spend time in prison is a
    tremendous   advantage    to   have   in   plea
    negotiations.     Indeed, the clients the
    undersigned   counsel   represents    typically
    would not accept a plea offer involving a
    prison sentence under any circumstances, and
    that is a tremendous advantage to have in plea
    negotiations. Here, Mr. Pina-Nieves lost that
    advantage, and any upper hand or leverage, in
    his plea negotiations, on account of the
    government's violation of his sacred right to
    confidential attorney-client communications.
    With this advantage, the government could
    adjust its negotiation strategy, knowing it
    could always maintain a string [sic] hand and
    a bottom line which involved time in prison.
    This makes the plea negotiations which have
    taken place to date, and any that could have
    taken place in the future, a complete sham.
    - 19 -
    (Emphasis added).
    The government opposed the motion.              But, in doing so,
    the government notified Pina-Nieves that it intended to admit into
    evidence pursuant to Rule 801(d)(2)(C) and Rule 801(d)(2)(D) the
    sentence from the motion's above-quoted passage that we have
    underlined: "Just the fact that the government learned that the
    defendant was resigned to the fact that he would have to spend
    time   in   prison    is   a   tremendous      advantage    to   have    in   plea
    negotiations."
    Rule     801(d)(2)    provides      in   relevant    part     that    a
    statement is not hearsay if it is "offered against an opposing
    party and: . . . (C) was made by a person whom the party authorized
    to make a statement on the subject; [or] (D) was made by the
    party's agent or employee on a matter within the scope of that
    relationship   and     while     it   existed."      Rule   801(a)      defines   a
    "statement" as "a person's oral assertion, written assertion, or
    nonverbal conduct, if the person intended it as an assertion."
    Pina-Nieves opposed the admission into evidence of the
    sentence in question on the ground that it did not fall within
    either Rule 801(d)(2)(C) or Rule 801(d)(2)(D) and was not otherwise
    admissible.    The District Court disagreed after concluding that,
    "[a]s defense counsel, Rebollo is authorized to represent Pina
    before the Court.      Rebollo's statements are, thus, attributable to
    - 20 -
    Pina."   United States v. Pina-Nieves, 
    575 F. Supp. 3d 270
    , 275
    (D.P.R. 2021).
    Pina-Nieves   continued   to   object   at   trial   to   the
    admission of the sentence in question on the ground that it did
    not fall within either Rule 801(d)(2)(C) or Rule 801(d)(2)(D), but
    to no avail. In addition, Pina-Nieves objected to the government's
    request on the first day of trial that the District Court take
    "judicial notice" of the sentence in the motion to dismiss.         The
    District Court nonetheless instructed the jury, prior to the
    calling of any witnesses, as follows:
    Judicial notice is taken that on December 11,
    2021, counsel for Defendant Rafael Pina-Nieves
    made the following statement in a motion filed
    in the Electronic Docket and Case Management
    System in this court, at Entry Number 168, as
    follows: Quote:
    Just the fact that the government learned that
    the defendant was resigned to the fact that he
    would have to spend time in prison is a
    tremendous   advantage   to   have   in   plea
    negotiations.
    This judicially-noticed fact can be so
    accurately and readily determined that it
    cannot be reasonably disputed.   You may,
    therefore, reasonably treat this fact as
    proven, even though no evidence has been
    presented on this point.
    As with any fact, however, the final decision
    whether to -- whether or not to accept it is
    for you to make. You are not required to agree
    with me.
    - 21 -
    At    the     close   of    evidence,       and    over    Pina-Nieves's
    objection, the District Court repeated this instruction almost
    verbatim.        The government then began its closing argument by
    quoting the sentence at issue and arguing that it was "evidence of
    consciousness of guilt." The government also included the sentence
    in large text in a PowerPoint presentation it used during closing
    argument    and    rebuttal.       During      its    rebuttal,       the   government
    revisited    the    sentence      at    issue,       calling   it     "incriminating
    evidence coming also from the defense camp."                   Then, after quoting
    the sentence once more, the government stated: "That wasn't a
    witness that we brought to testify something the defendant told
    that witness.       No.    No.    No.    That was the defense attorneys in
    black and white, in a motion.              Two words come to mind from our
    behalf: Thank you.         More evidence of guilt."
    2.
    The government contends that the "just the fact that"
    sentence is a "written assertion," see Rule 801(a), and so a
    "statement"       within    the    meaning       of     Rule    801(d)(2)(C)       and
    801(d)(2)(D).       That is so, the government contends, because the
    sentence makes a legal argument about why the government's alleged
    misconduct would be prejudicial that has "embedded" within it an
    assertion of fact about Pina-Nieves's state of mind.
    The government goes on to contend that the sentence
    qualifies as an admissible statement under those subsections of
    - 22 -
    Rule 801(d)(2).       That is so, according to the government, because
    the assertion of fact that the sentence makes about Pina-Nieves's
    state of mind is attributable to Pina-Nieves himself, given that
    Pina-Nieves's counsel, Rebollo-Casalduc, filed the motion that
    contains the sentence.
    But, the introductory phrase "just the fact that" in the
    sentence    at    issue   is   most    naturally   read   to   be   merely   the
    colloquial means by which the beginning of the sentence conveys
    the consequence that is then spelled out in the remainder of that
    sentence.        So understood, the sentence is most naturally read
    merely to be making a legal argument about the prejudice that would
    follow if the government had             "learned"   a certain fact      about
    Pina-Nieves's state of mind through alleged misconduct, rather
    than to be making such a legal argument while also asserting that
    the government had learned of any fact about Pina-Nieves's state
    of mind.
    The government does point out that the motion to dismiss
    the indictment argues that the government's misconduct prejudiced
    Pina-Nieves      by   enabling   the    government   to   obtain    access   to
    information about Pina-Nieves's state of mind and that this access
    to that information in turn gave the government an "extra advantage
    in plea negotiations."         The government goes on to contend that it
    could have obtained that "extra advantage" only if Pina-Nieves
    was, in fact, resigned to spend time in prison.                      Thus, the
    - 23 -
    government argues, the sentence in question, when read in the
    context of the motion as a whole, must be read to be impliedly
    making the factual assertion that Pina-Nieves was so resigned and
    not merely to be making the legal argument that the government's
    misconduct would be prejudicial if the government had learned that
    Pina-Nieves had that state of mind.
    We must focus, however, on what the sentence that was
    admitted into evidence pursuant to Rule 801 itself says.             It is
    that sentence -- and that sentence alone -- that was deemed to
    qualify as a "statement" admissible under Rule 801.             Yet, with
    that focus in mind, we conclude that the government's "reading is
    not compelled by the language of the [sentence]," Harrington v.
    City of Nashua, 
    610 F.3d 24
    , 31 (1st Cir. 2010).
    True, the sentence appears as part of the motion's
    broader argument about how the government's asserted misconduct is
    prejudicial.    But, the sentence does not make an assertion about
    what Pina-Nieves's state of mind was or even a representation that
    the government had learned of his state of mind.         It explains how
    prejudice could flow from the government having "learned" such a
    "fact" without thereby itself asserting that the government had
    learned any such fact.
    Nor   need   the   sentence    have   made   any   such   factual
    assertion to have advanced the broader prejudice argument that the
    motion to dismiss the indictment makes.         In context, the sentence
    - 24 -
    served the useful function of spelling out how the government's
    knowledge of a fact about Pina-Nieves's state of mind with respect
    to   being   resigned      to   spend    time       in   prison   could     have    hurt
    Pina-Nieves in plea negotiations insofar as the government had
    such knowledge.
    Thus,   the    government     fails         to   demonstrate    that    the
    sentence     in   question      included       an    assertion      of    fact     about
    Pina-Nieves's state of mind within the legal argument that it was
    making about prejudice.           See 
    id.
               Accordingly, we agree with
    Pina-Nieves that the District Court abused its discretion in
    admitting the sentence in question pursuant to Rule 801.                     See Gill
    v. Maciejewski, 
    546 F.3d 557
    , 563 (8th Cir. 2008) (counsel's
    statements during a criminal trial not admissible under Fed. R.
    Evid. 801(d)(2)(C) or (D) where opposing party took "unwarranted
    liberties with the context of the statement"); United States v.
    Blood, 
    806 F.2d 1218
    , 1221 (4th Cir. 1986).
    B.
    We now turn to the claimed error by the District Court
    that implicates Rule 401.               It concerns           the District Court's
    exclusion of the testimony of Pina-Nieves's realtor in Miami,
    Florida, Jordan Millman.          We first lay out the pertinent facts.
    We then explain why we conclude that there was error.
    - 25 -
    1.
    On the sixth day of trial, Millman testified that he met
    Pina-Nieves at the end of 2010, when Pina-Nieves was looking at
    apartments in Miami, and that Millman had personal knowledge of
    Pina-Nieves living in Miami in 2010 because Millman lived in the
    same   building.    The   government    then   objected   to   Millman's
    testimony, pursuant to Federal Rule of Evidence 401, which provides
    that "[e]vidence is relevant if: (a) it has any tendency to make
    a fact more or less probable than it would be without the evidence;
    and (b) the fact is of consequence in determining the action."
    The District Court struck the testimony from Millman
    that he had already provided and barred the remainder. Pina-Nieves
    subsequently made the following offer of proof to no avail:
    [Millman] would have testified that in 2010,
    he assisted Mr. Pina in renting an apartment
    at the Epic, that he lived in that apartment
    through 2013.   That in 2013, that apartment
    was sold, and he moved to Aventura, and that
    in 2016, he assisted Mr. Pina in starting to
    -- towards the end of 2016, in starting to
    look for properties to buy, that he purchased
    an apartment in 2019.        He has personal
    knowledge that he lived there, and that he
    sold that apartment in 2021 and bought a house
    in north Miami.
    2.
    Our standard of review for a Rule 401 ruling by a
    district court is quite deferential, given the trial judge's
    closeness to the record.    See Bielunas v. F/V Misty Dawn, Inc.,
    - 26 -
    
    621 F.3d 72
    , 76 (1st Cir. 2010).            Nonetheless, "[r]elevancy is a
    very low threshold . . . . And 'the evidence need not definitively
    resolve a key issue in the case,' but rather 'need only move the
    inquiry forward to some degree.'"            United States v. Cruz-Ramos,
    
    987 F.3d 27
    , 42 (1st Cir. 2021) (quoting Bielunas, 
    621 F.3d at 76
    ).
    Pina-Nieves    no     doubt     could    have      been   clearer     in
    explaining to the District Court how the testimony from his realtor
    would have advanced his defense.            Nonetheless, we are persuaded
    that the excluded Millman testimony crossed the low threshold for
    relevance that Rule 401 establishes.
    According to Pina-Nieves's proffer, Millman would have
    testified   that   he   had     "personal    knowledge"        that   Pina-Nieves
    "lived" in the Miami apartment that he purchased in 2019 and that
    he did not sell that apartment until 2021.                    That testimony was
    relevant to Pina-Nieves's contention that he was so distant from
    the Caguas Real house that he could not have either intended to
    exercise dominion and control over the weapons in question or known
    of the characteristics of the modified Glock pistol that made it
    a machinegun.
    Millman's testimony also provided support for finding
    that Pina-Nieves had residences outside of Puerto Rico from prior
    to the time that the modified Glock pistol had first been purchased
    in   Ohio   in   2016   through    the    time      he   is    alleged   to     have
    - 27 -
    constructively possessed the weapon.    In that respect, too, then,
    Millman's testimony would have "move[d] the inquiry forward to
    some degree" by bolstering Pina-Nieves's contention that he was
    sufficiently removed from the goings-on at the Caguas Real property
    on or about April 1, 2020 that he lacked both the intent to exercise
    dominion and control over the weapons found there at that time and
    the knowledge of the characteristics of the modified Glock pistol
    that made it a machinegun.
    C.
    We turn, then, to the government's arguments that each
    of the errors was harmless. And, that is, the government contends,
    even if we account for their cumulative effect.   See United States
    v. Sepulveda, 
    15 F.3d 1161
    , 1195-96 (1st Cir. 1993).        For the
    reasons we will next explain, we agree with the government.
    To prove that Pina-Nieves was guilty of the § 922(g)(1)
    charge, the government was required to prove beyond a reasonable
    doubt that Pina-Nieves was a felon who possessed firearms or
    ammunition on or about April 1, 2020.   Pina-Nieves stipulated that
    he became a felon in 2015.   Thus, the only element in dispute is
    the possession element, which the government contends is satisfied
    solely due to the evidence in the record that it contends shows
    that Pina-Nieves constructively possessed firearms or ammunition
    at the time specified in the underlying charge.
    - 28 -
    To show such constructive possession, the government was
    required to prove beyond a reasonable doubt that, on or about April
    1, 2020, Pina-Nieves knowingly had the power and intention of
    exercising dominion and control over firearms or ammunition.          See
    United States v. Tanco-Baez, 
    942 F.3d 7
    , 25 (1st Cir. 2019).          And
    to so prove, the record, as a whole, "must contain evidence of
    'some action, some word, or some conduct that links the individual
    to the [firearm] and indicates that he had some stake in it, some
    power over it.'"   Ridolfi, 
    768 F.3d at 62
     (alteration in original)
    (quoting United States v. McLean, 
    409 F.3d 492
    , 501 (1st Cir.
    2005)).
    The   wrongly   admitted   Rule   801   evidence   was   plainly
    highly prejudicial with respect to any disputed element and thus
    with respect to the possession element.           See United States v.
    Canty, 
    37 F.4th 775
    , 792 (1st Cir. 2022).         Indeed, the government
    emphasized that evidence in its closing argument and rebuttal and
    described it as "incriminating," while also stating that it came
    from the "defense camp."
    In addition, the Millman testimony was relevant to the
    question of Pina-Nieves's constructive possession of the firearms
    and ammunition in question as of the date set forth in the
    underlying charge.    And, while the government contends that the
    Millman testimony was merely cumulative of other evidence that
    showed that "Pina resided during the pertinent time period in
    - 29 -
    places other than the Caguas Real house," it would have added,
    with respect to Pina-Nieves's connection to the Miami apartment,
    Millman's "personal knowledge that [Pina-Nieves] lived there" from
    2010 through 2021.      That testimony also would have provided, as
    Pina-Nieves     contends,       details    about    "Pina's       more   recent
    acquisitions of property, and residence in, Miami" while the
    "development of Millman's relationship with Pina over time would
    have provided important background regarding how Millman and Pina
    became sufficiently close friends that Millman was in a position
    to have personal knowledge of how much time Pina spent in Miami."
    Nonetheless, the question we must answer in assessing
    harmless error is not merely whether the two errors, either alone
    or in combination, had some prejudicial effect as to the possession
    element,   as   they   surely    did.      The   question    is    whether   the
    government has met its burden to show that it is "highly probable"
    that the errors, even if considered in combination, did not affect
    the guilty verdict on the § 922(g)(1) charge.          See Piper, 
    298 F.3d at 56
    ; Sepulveda, 
    15 F.3d at 1195-96
    .              And, in answering that
    question, we cannot ignore the strength of the evidence of guilt
    with respect to the conviction at issue, see Sepulveda, 
    15 F.3d at 1196
    ,   which   we   conclude    is    overwhelming   as    to    Pina-Nieves's
    constructive possession.
    Pina-Nieves does argue -- based on the "outsized stress"
    that the government placed on the wrongly admitted "just the fact
    - 30 -
    that" sentence -- that the Rule 801 error was not harmless because
    "the government knew full well the devastating impact the evidence
    would have upon the jury's ability to fairly weigh the evidence
    against Pina."    Pina-Nieves nowhere disputes in his briefing to
    us, however, the government's contention that he could be convicted
    on   the   charged   § 922(g)(1)   offense   based   on   his   having
    constructively possessed firearms or ammunition on February 6,
    2020.   And that is significant because, as Pina-Nieves admits, the
    transcript of the February 6 phone call shows that he referred in
    that call, which concerned what was in the Caguas Real house, to
    "my guns" -- or, as he concedes in his briefing, "pistols" -- as
    well as ammunition being there.
    To be sure, Pina-Nieves contends that the transcript
    does not show -- let alone overwhelmingly -- that he had the intent
    to exercise dominion and control over any such weapons.     He argues
    that the transcript shows, in fact, the opposite, as he contends
    that it shows that he "declin[ed] to exercise dominion and control"
    over the guns and bullets to which he referred on the phone call
    and "even indicat[ed] that he cannot exercise dominion and control
    over them."   Thus, on his telling, the transcript of the February
    6 call shows him "rejecting every suggestion of what might be done
    with the weapons and ammunition and deferring any decision until
    he returned to Puerto Rico at some unspecified time in the future."

    But, the transcript of the February 6 phone call shows
    that the call took place in the context of Pina-Nieves deciding
    how to prepare the Caguas Real house that he owned to be rented or
    sold by deciding what items he intended to store in a warehouse,
    what items he intended to give away, what items he intended to
    keep with the Caguas Real house, and what items he intended to
    keep for himself either at the Caguas Real house or his second
    house in Puerto Rico, where all parties agree that Pina-Nieves
    actually   lived   when   in   Puerto    Rico.     And,   according   to    the
    transcript, Pina-Nieves not only first raised the issue of the
    "safe" and later told the other party to the call, Romero-Soler,
    what the "safe" contained but also left no doubt it contained guns
    and   bullets   that   were    his,   as   he    described   the   "safe"    as
    containing: "my guns, rifles, bullets" (emphasis added).
    Moreover, and crucially, the transcript does not just
    show that Pina-Nieves understood the weapons and ammunition to
    which he referred      to be his own.            It also shows     that when
    Romero-Soler suggested that Pina-Nieves "have Miguel take out
    anything he needs to take out," then "reset [the keypad on the
    hidden room's door]" and "leave [the door] open behind there so
    that whoever moves in there will use it," Pina-Nieves responded
    emphatically in the negative.           Because prohibiting action is as
    much an exercise of dominion and control as allowing action, the
    transcript therefore shows that Pina-Nieves claimed on February 6,
    - 32 -
    2020 that guns and ammunition that were located in a private area
    of the house that he owned were his own, that on that date an
    associate of his had sought out his direction about what to do
    with those guns and that ammunition, and that he had responded to
    that associate's request for that direction by giving it in no
    uncertain terms.
    We thus do not see how the transcript may be read other
    than to show that Pina-Nieves had "some stake in" the firearms and
    ammunition he called "my" guns and bullets as of February 6, 2020,
    see Ridolfi, 
    768 F.3d at 62
    , a date that Pina-Nieves does not
    dispute   is   "on   or   about   April   1,   2020."   Accordingly,   the
    government has met its burden to show harmless error because the
    overwhelming nature of the evidence of Pina-Nieves's constructive
    possession of weapons and ammunition "on or about April 1, 2020"
    makes it "highly probable" that the evidentiary errors did not
    affect the verdict of guilt on the § 922(g)(1) charge.        See Piper,
    
    298 F.3d at
    56–58.1
    1 Pina-Nieves does argue that the exclusion of the Millman
    evidence deprived him under the U.S. Constitution of his Fifth and
    Sixth Amendment rights to mount a defense and that the admission
    of the "just the fact that" sentence from his motion to dismiss
    deprived him under the U.S. Constitution of his Sixth Amendment
    right to conflict-free counsel. But, we need not address those
    challenges in any detail because each fails for the same reasons
    that we conclude that the Rule 801 and Rule 401 errors are
    harmless: the evidence of guilt concerning the only disputed
    element of this conviction is overwhelming. See United States v.
    Cardona-Vicenty, 
    842 F.3d 766
    , 772 (1st Cir. 2016); United States
    v. Pizarro, 
    772 F.3d 284
    , 287 (1st Cir. 2014).
