    Before HARTZ, McKAY, and MORITZ, Circuit Judges.
    _________________________________
    A jury convicted Leilani Martinez on seven criminal counts: two counts of being a
    felon in possession of a firearm or ammunition, one count of possessing a firearm during
    and in furtherance of a drug-trafficking crime, one count of conspiring to distribute a
    controlled substance, and three counts of knowingly and intentionally distributing a
    controlled substance. She appeals. Finding no reversible error, we affirm.

    This order and judgment isn’t binding precedent, except under the doctrines
    of law of the case, res judicata, and collateral estoppel. But it may be cited for its
    persuasive value. See Fed. R. App. P. 32.1; 10th Cir. R. 32.1.
    Background
    In April 2014, the Pueblo Police Department learned that Leilani and Colter
    Martinez1 were selling drugs from a residence on Agate Street in Pueblo, Colorado. A
    few days later, a confidential informant verified this report. Officers then surveilled
    the residence and observed activity consistent with drug trafficking. These
    observations led Pueblo Detective Michael Sincerbox to set up a controlled drug
    purchase between the informant and Leilani at the residence. During the controlled
    purchase, the informant handed $150 to Colter, who passed the money to Leilani. She
    then weighed some heroin and gave it to the informant.
    Sometime after the controlled buy, Leilani moved to a new residence on James
    Avenue in Pueblo. Officers installed a “covert type camera” on a telephone pole
    nearby. R. vol. 3, 99. This camera captured activity similar to the activity observed at
    the previous residence—i.e., frequent traffic to and from the residence, with those
    who came and went often staying only a short while.
    In June 2014, Sincerbox orchestrated a second controlled drug purchase
    between the informant and Leilani. This transaction occurred in the new residence’s
    northwest bedroom. When the informant entered the bedroom, Leilani grabbed a safe
    from under the bed, handed it to Colter, and instructed him to complete the
    transaction. The informant gave $150 to Colter, who left the bedroom to weigh the

    them by their first names.
    2
    heroin in the kitchen. Colter returned to the bedroom and gave the heroin to the
    informant.
    After this second controlled purchase, Sincerbox secured a search warrant for
    Leilani, her car, and the residence. Pueblo police officers subsequently trailed Leilani
    as she drove from her residence and eventually pulled her over. They then searched
    the residence and Leilani’s car. In the northwest bedroom—the location of the second
    controlled purchase—they found (1) a loaded 12-gauge shotgun between the mattress and
    box spring; (2) a bag containing ammunition on top of the bed; (3) an unlocked safe
    under the bed, which contained about $1,300 in cash, a handgun, heroin, crack cocaine,
    and methamphetamine; and (4) 113 grams of methamphetamine and about 150 grams of
    heroin in several different packages within a larger bag in the bottom drawer of a dresser.
    In addition to the gun, ammunition, and drugs, the officers also found in the northwest
    bedroom (1) women’s clothing; (2) a Western Union receipt bearing Leilani’s name;
    (3) mail listing Leilani’s name and address; (4) a stylized sign on the wall that read
    “Leilani,” R. vol. 3, 122; and (5) medication belonging to Leilani on the nightstand.
    Further, the informant identified this bedroom as Leilani’s room. In the northeast
    bedroom, officers found another shotgun and a black nylon tactical vest in the closet.2
    And in the living room they found a digital scale on a coffee table. In Leilani’s car,
    officers discovered 50 grams of heroin and $938 in cash.
    2
    Although this room is characterized as a bedroom, it did not contain a bed.
    And other than the tactical vest, it contained no clothing. But inside the room,
    officers did find a pink plastic box with the name “Poco” on it. “Poco” is Colter’s
    street name. And the informant identified this bedroom as Colter’s room.
    3
    Based on this evidence, the government charged Leilani with seven criminal
    counts, including being a felon in possession of a firearm and ammunition in
    violation of 18 U.S.C. § 922(g)(1), possessing a firearm in furtherance of a drug-
    trafficking crime in violation of 18 U.S.C. § 924(c)(1)(A), and distributing and
    possessing with the intent to distribute a controlled substance in violation of 21
    U.S.C. § 841(a)(1). A jury convicted Leilani on all counts. She appeals.
    Analysis
    I.       Sufficiency of the Evidence
    Leilani first challenges the sufficiency of the evidence for her convictions under
    § 922(g)(1) and § 924(c)(1)(A). We review Leilani’s claim de novo and apply “the law
    in effect at the time of trial.” United States v. Benford, 
    875 F.3d 1007
    , 1014 (10th Cir.
    2017). “In doing so, we consider both direct and circumstantial evidence, and all
    reasonable inferences therefrom, in the light most favorable to the government.” United
    States v. Weidner, 
    437 F.3d 1023
    , 1032 (10th Cir. 2006). We will find the evidence
    sufficient so long as “a reasonable jury could have found the defendant guilty beyond a
    reasonable doubt.” United States v. Acosta-Gallardo, 
    656 F.3d 1109
    , 1123 (10th Cir.
    2011).
    To sustain a conviction under § 922(g)(1), “the [g]overnment [must] prove
    (1) knowing possession; (2) by a restricted person; (3) of any firearm or ammunition
    that has traveled in or affected interstate commerce.” United States v. Hien Van Tieu,
    
    279 F.3d 917
    , 922 (10th Cir. 2002), abrogated on other grounds by Henderson v.
    United States, 
    135 S. Ct. 1780
    (2015). Similarly, as pertinent here, to sustain a
    4
    conviction under § 924(c)(1)(A), the government must prove the defendant possessed
    “a firearm in furtherance of a drug[-]trafficking crime.” United States v. Villa, 
    589 F.3d 1334
    , 1341 (10th Cir. 2009). Because Leilani argues only that the government
    failed to prove she possessed the shotgun and ammunition, we focus solely on that
    element in evaluating the sufficiency of the evidence. Similarly, because the
    government presented no evidence that Leilani actually possessed these items, we
    analyze only whether it presented sufficient evidence to prove that Leilani
    constructively possessed them. See United States v. Lott, 
    310 F.3d 1231
    , 1247 (10th
    Cir. 2002) (stating possession can be actual or constructive).
    A person has constructive possession of a firearm or ammunition if, inter alia,
    he or she has dominion and control over the object. United States v. Ledford, 
    443 F.3d 702
    , 713 (10th Cir. 2005), abrogated by Henderson, 
    135 S. Ct. 1780
    .
    “Dominion, control, and knowledge, in most cases, may be inferred if a defendant
    had exclusive possession of the premises [where the firearm or ammunition was
    found]; however joint occupancy alone cannot sustain such an inference.” United
    States v. Mills, 
    29 F.3d 545
    , 549 (10th Cir. 1994). Instead, when multiple individuals
    jointly occupy the premises, as we will assume was the case here,3 the government
    must “show some connection or nexus between the defendant and the firearm [or
    3
    The government argues that Leilani exclusively occupied the northwest
    bedroom, and therefore the jury could have inferred that she had knowledge of the
    firearm and ammunition. Leilani disagrees, asserting that the evidence showed she
    and Colter jointly occupied the bedroom. We need not resolve this disagreement
    because even assuming Leilani and Colter jointly occupied the bedroom, we conclude
    the government presented sufficient evidence for a reasonable jury to find that she
    knew about the shotgun and ammunition.
    5
    ammunition].” 
    Id. In other
    words, convictions for constructive possession in joint-
    occupancy cases require “some evidence supporting at least a plausible inference that
    the defendant had knowledge of and access to the weapon [or ammunition].” 
    Id. at 550
    (quoting United States v. Mergerson, 
    4 F.3d 337
    , 349 (5th Cir. 1993)).
    Additionally, the individual must have intended to exercise dominion or control over
    the firearm or ammunition.4 See 
    Henderson, 135 S. Ct. at 1784
    . Here, Leilani
    contends that no reasonable jury could find beyond a reasonable doubt that she either
    (1) knew about or (2) intended to exercise control over the shotgun and ammunition.
    A.     Knowledge
    Leilani first argues the evidence was insufficient to prove she knew about the
    shotgun and ammunition because (1) the shotgun was hidden from plain sight, (2) she
    never spoke about the shotgun, (3) no one saw her with the shotgun, and (4) neither
    her fingerprints nor DNA were found on the shotgun. According to Leilani, the only
    4
    As we discuss below, see infra Part II.B., the parties agree the district court
    erred in failing to instruct the jury that constructive possession requires proof of
    intent. And because the district court failed to instruct the jury on this element of
    constructive possession, the jury didn’t necessarily find it beyond a reasonable doubt.
    But for purposes of this appeal, that doesn’t alter our approach to Leilani’s
    sufficiency argument, under which we ask only whether a reasonable jury could have
    found that she intended to exercise dominion or control over the firearm and
    ammunition. See 
    Acosta-Gallardo, 656 F.3d at 1123
    ; cf. Musacchio v. United States,
    
    136 S. Ct. 709
    , 715 (2016) (explaining that “a sufficiency challenge should be
    assessed against the elements of the charged crime” and that “[a] reviewing court’s
    limited determination on sufficiency review thus does not rest on how the jury was
    instructed”; instead, “[t]he reviewing court considers only the ‘legal’ question
    ‘whether, after viewing the evidence in the light most favorable to the prosecution,
    any rational trier of fact could have found the essential elements of the crime beyond
    a reasonable doubt’” (quoting Jackson v. Virginia, 
    443 U.S. 307
    , 319 (1979))).
    6
    evidence of her knowledge was the fact that police found the shotgun and
    ammunition in “a bedroom she and Colter shared.” Aplt. Br. 27.
    We disagree. To begin, the evidence overwhelmingly connects Leilani to the
    bedroom. Specifically, the bedroom contained (1) women’s clothing—which the jury
    could have reasonably inferred belonged to Leilani; (2) mail bearing Leilani’s name
    and address; (3) a receipt with Leilani’s name on it; (4) medication belonging to
    Leilani; and (5) a stylized sign of Leilani’s name. This evidence demonstrates Leilani
    “occupied th[e] room and had knowledge of its contents.” United States v. Mendez,
    
    514 F.3d 1035
    , 1042 (10th Cir. 2008), abrogated on other grounds by Henderson,
    
    135 S. Ct. 1780
    ; see also Hien Van 
    Tieu, 279 F.3d at 922
    & n.3 (finding that
    defendant had knowledge of firearm in jointly occupied room, in part because
    defendant “used the room to store his personal effects”); United States v. Boykin, 
    986 F.2d 270
    , 274 (8th Cir. 1993) (explaining that finding defendant’s “personal
    belongings” in same room as firearms contributed to proof of defendant’s knowledge
    of firearms in that room). The informant also testified at trial that the bedroom
    belonged to Leilani. See 
    Boykin, 986 F.2d at 274
    (explaining that witness’
    confirmation that defendant resided in jointly occupied room supported finding of
    defendant’s knowledge of firearm in that room). Thus, a reasonable jury could have
    inferred that Leilani had knowledge of the shotgun. Indeed, this conclusion is
    particularly reasonable here, where a finding that the bedroom belonged at least
    partially to Leilani would give rise to a concomitant finding that she slept in the only
    7
    bed located in that room—the same bed where officers found the shotgun sandwiched
    between the mattress and box spring.
    In arguing otherwise, Leilani relies on the Fifth Circuit’s decision in
    Mergerson, 
    4 F.3d 337
    . There, the defendant was convicted of being a felon in
    possession of a firearm after officers found a handgun beneath the mattress and box
    spring in a bedroom that the defendant shared with his girlfriend. 
    Id. at 348.
    On
    appeal, the defendant argued that the evidence was insufficient to prove he
    constructively possessed the firearm. 
    Id. The Fifth
    Circuit agreed, noting that the
    weapon was hidden from plain view and “there were no other circumstantial indicia
    that established” the defendant’s knowledge of the weapon. 
    Id. at 349.
    In fact, the
    circumstantial evidence in that case pointed in the other direction—the evidence
    included a pawn-shop receipt that showed the defendant’s girlfriend bought the
    handgun well before the defendant moved into the room with her. 
    Id. at 348–49.
    Here, Leilani doesn’t point to any similarly exculpatory evidence that might
    indicate Colter purchased the shotgun. And unlike the handgun in Mergerson, which
    officers found underneath both the mattress and box spring, officers found the
    shotgun at issue in this case underneath the mattress alone, making it less likely that
    Leilani failed to notice the shotgun’s contours as she slept. Cf. Daniel L. Graham,
    Statutory Marksmanship: Enacting Laws That Reduce Gun-Related Crime and
    Accidents, 4 Phx. L. Rev. 461, 468 (2010) (“[H]andguns are much smaller and lighter
    than . . . shotguns and are therefore easier to . . . conceal.”). As such, the jury could
    have plausibly inferred that Leilani slept on the bed, and in turn knew about the shotgun
    8
    between the mattress and box spring. See 
    Mendez, 514 F.3d at 1042
    (holding that
    defendant knew about shotgun under mattress in jointly occupied room, in part
    because defendant slept on bed, which showed defendant “occupied th[e] room and
    had knowledge of its contents”); Hien Van 
    Tieu, 279 F.3d at 919
    , 922 & n.3
    (concluding that defendant knew about handgun in jointly occupied room under
    mattress on which he slept).
    Evidence that Leilani knew there were drugs in the bedroom further
    establishes her knowledge of the shotgun. The informant testified that he purchased
    drugs from Leilani in the bedroom. And during the transaction, he saw Leilani reach
    under the bed, hand a safe to Colter, and instruct Colter to weigh the drugs in the
    kitchen. On the day of the search, officers found the safe under the bed and recovered
    drugs, money, and a handgun from inside the safe. Because the evidence showed
    Leilani knew there were concealed drugs in her bedroom, a reasonable jury could
    have inferred that she also knew about the shotgun sandwiched between the mattress
    and box spring. See 
    Mendez, 514 F.3d at 1041
    –42 (finding that where evidence
    indicated defendant knew of drug ledger hidden under mattress in jointly occupied
    bedroom, defendant’s awareness of ledger supported jury’s finding that defendant
    was also aware of firearm found under same mattress); United States v. Finney, No.
    93-5190, 
    1994 WL 263678
    , at *4 (10th Cir. June 16, 1994) (unpublished) (holding
    that there was sufficient evidence of defendant’s knowledge of firearm in jointly
    occupied bedroom because defendant “rented the house, occupied the bedroom, and
    used the house as a base of operations for drug trafficking”).
    9
    Moreover, the evidence was likewise sufficient to establish Leilani’s
    knowledge of the ammunition. Officers found the ammunition in a bag in plain view on
    top of the bed. And on the day of the search, no one entered or exited the residence from
    the time Leilani left the residence until the time the officers searched it. Under these
    circumstances, a jury could have plausibly inferred that Leilani knew about the
    ammunition on top of the bed.
    Viewing the evidence in the light most favorable to the government, we conclude
    that a reasonable jury could find Leilani was aware of both the shotgun and the
    ammunition.
    B.         Intent
    Next, Leilani argues there was insufficient evidence of her intent to exercise
    control over the shotgun and ammunition because (1) there was no evidence she owned
    the shotgun; (2) there was no evidence she spoke of, used, or saw the shotgun; (3) there
    was no evidence she exercised control over the shotgun; and (4) the shotgun wasn’t found
    in plain sight.
    But Leilani ignores the overwhelming evidence of drug trafficking in the bedroom.
    See United States v. Johnson, 
    26 F.3d 669
    , 685 (7th Cir. 1994) (noting that court “will
    find that a defendant intended to use the firearm in facilitation of a drug[-]related crime
    ‘if it [is] strategically located so as to be quickly and easily available for use during
    a drug transaction’” (second alteration in original) (quoting United States v. Wilson, 
    938 F.2d 785
    , 791 (7th Cir. 1991))); cf. United States v. Gambino-Zavala, 
    539 F.3d 1221
    ,
    1230 (10th Cir. 2008) (stating that it’s reasonable for jury to conclude firearms assist
    10
    drug dealers). Testimony established that Leilani was a high-level drug dealer who sold
    drugs to the informant in the bedroom. The evidence also showed the bedroom contained
    133 grams of methamphetamine, 150 grams of heroin, $1,300 in cash, and distribution
    packaging. Further, witnesses identified the shotgun as a “tactical type shotgun”—as
    opposed to a shotgun that’s used for sport—and testified that drug traffickers possess
    firearms to protect themselves, their products, and their proceeds. R. vol. 3, 334.
    Accordingly, the jury could have reasonably inferred that (1) Leilani placed the
    shotgun and ammunition in the bedroom for the purpose of protecting herself and her
    drug supply during drug sales, and (2) she therefore intended, for purposes of
    § 924(c)(1)(A), to possess the shotgun. And it necessarily follows that the jury had
    sufficient evidence to find Leilani intended to possess the shotgun and ammunition under
    § 922(g)(1), as well. See United States v. Rogers, 
    556 F.3d 1130
    , 1140 n.5 (10th Cir.
    2009).
    Thus, we conclude the jury had sufficient evidence to find Leilani constructively
    possessed the shotgun under both statutes and the ammunition under § 922(g)(1).
    II.      The Jury Instruction
    Leilani next challenges the jury instruction on constructive possession. The
    instruction applied to three of the seven charges at issue: (1) being a felon in
    possession of a firearm under § 922(g)(1); (2) being a felon in possession of
    ammunition under § 922(g)(1); and (3) possessing a firearm in furtherance of a drug-
    trafficking crime under § 924(c)(1)(A). Specifically, Leilani argues that the district
    court erred in failing to instruct the jury that in order to convict her of constructively
    11
    possessing the shotgun and ammunition, it had to find that she intended to exercise
    control over them.
    A.     Invited Error
    Before reaching the merits of this argument, we note that Leilani didn’t object to
    this instruction below. As a result, she argues in her opening brief that we should review
    this argument for plain error. See United States v. Wolfname, 
    835 F.3d 1214
    , 1217 (10th
    Cir. 2016) (explaining that when litigant merely fails to object to jury instruction below,
    we will nevertheless review that instruction on appeal, albeit under our rigorous plain-
    error test). The government disagrees. It points out that Leilani didn’t simply fail to
    object to this instruction; rather, she stipulated to a proposed jury instruction that was
    identical to the one the district court ultimately provided. Thus, the government contends
    in its response brief, the invited-error doctrine precludes us from reviewing Leilani’s
    challenge to that instruction on appeal at all—even for plain error. Compare 
    id., with United
    States v. Jereb, 
    882 F.3d 1325
    , 1338 (10th Cir. 2018) (explaining that invited-
    error doctrine “prevents a party who induces an erroneous ruling from being able to have
    it set aside on appeal” (quoting United States v. Morrison, 
    771 F.3d 687
    , 694 (10th Cir.
    2014))), and United States v. Deberry, 
    430 F.3d 1294
    , 1302 (10th Cir. 2005) (noting that
    “invited-error doctrine precludes a party from arguing that the district court erred in
    adopting a proposition that the party . . . urged the district court to adopt”).
    In her reply brief, Leilani doesn’t dispute that she stipulated to the instruction. Nor
    does she dispute that such a stipulation would normally trigger the invited-error doctrine.
    But she nevertheless urges us to apply an exception to the invited-error rule: she points
    12
    out that if a party relied on settled law in advancing a particular position below, the party
    can advance a contrary position on appeal based on an intervening change in that settled
    law. See United States v. Titties, 
    852 F.3d 1257
    , 1264 n.5 (10th Cir. 2017) (“[T]he
    invited-error doctrine does not apply when a party relied [below] on settled law that
    changed while the case was on appeal.”). And according to Leilani, our decision in
    United States v. Little, 
    829 F.3d 1177
    (10th Cir. 2016), constituted just such an
    intervening change.
    In support, Leilani asserts that before we decided Little, the government didn’t
    have to prove a defendant intended to exercise control over a particular object to prove
    that he or she constructively possessed it. Compare 
    Little, 829 F.3d at 1182
    (“[C]onstructive possession exists when a person not in actual possession knowingly has
    the power and intent at a given time to exercise dominion or control over an object.”),
    with United States v. Colonna, 
    360 F.3d 1169
    , 1178–79 (10th Cir. 2004) (concluding that
    intent to exercise control over contraband isn’t required to prove constructive
    possession), abrogated by 
    Henderson, 135 S. Ct. at 1784
    . Moreover, Leilani points out,
    this court decided Little on July 19, 2016—five months after her February 2016 trial.
    Thus, she insists, our decision in Little constitutes an intervening change in the law and
    the invited-error doctrine doesn’t apply. Cf. 
    Titties, 852 F.3d at 1264
    n.5.
    But as the government pointed out at oral argument, the law of constructive
    possession didn’t change with our July 19, 2016 decision in Little. Instead, contrary to
    Leilani’s assertion, the law changed more than a year before that, when the Supreme
    Court decided Henderson on May 18, 2015. See 
    Henderson, 135 S. Ct. at 1784
    (holding
    13
    that an individual constructively possesses a firearm when he or she, “though lacking . . .
    physical custody, still has the power and intent to exercise control over the [firearm]”
    (emphasis added)). In other words, Little—which we decided five months after Leilani’s
    trial—merely recognized that Henderson—which the Supreme Court decided nine
    months before Leilani’s trial—“change[d] the law of constructive possession.” 
    Little, 829 F.3d at 1182
    ; see also 
    Titties, 852 F.3d at 1269
    (establishing that Mathis v. United States,
    
    136 S. Ct. 2243
    (2016), changed the law despite lack of Tenth Circuit case recognizing
    Mathis).5 And because it has been settled since May 18, 2015, that intent is an element of
    constructive possession, Leilani didn’t rely on settled law when she stipulated on
    February 22, 2016, to an instruction that erroneously omitted any reference to that
    element. See 
    Henderson, 135 S. Ct. at 1784
    . Accordingly, we hold that the invited-error
    doctrine bars Leilani’s challenge to the constructive-possession jury instruction.
    5
    Although the parties don’t mention it, we note that we have previously
    suggested, albeit in dicta, that Little changed the law of constructive possession in this
    circuit. See United States v. Simpson, 
    845 F.3d 1039
    , 1060 (10th Cir. 2017) (“During this
    appeal, the law changed when our court held that constructive possession contains an
    additional element: intent.” (emphasis added)).
    This distinction didn’t matter in Simpson because both Henderson and Little
    postdated the Simpson verdict. Thus, the Simpson court had no reason to resolve
    whether it was Henderson or Little that changed the law of constructive possession in
    this circuit; either way, the law “changed while the case was on appeal.” 
    Titties, 852 F.3d at 1264
    n.5. Accordingly, we aren’t bound by Simpson’s pronouncement that it
    was Little, as opposed to Henderson, that changed the law. Compare White v. Chafin,
    
    862 F.3d 1065
    , 1066 (10th Cir. 2017) (“[W]e cannot overrule published opinions by
    other Tenth Circuit panels.”), with Bates v. Dep’t of Corr., 
    81 F.3d 1008
    , 1011 (10th
    Cir. 1996) (“[A] panel of this [c]ourt is bound by a holding of a prior panel of this
    [c]ourt but is not bound by a prior panel’s dicta.”).
    14
    Alternatively, even if we agreed with Leilani that the invited-error doctrine doesn’t
    apply, we would treat her instructional challenge as forfeited and review it only for plain
    error. See 
    Jereb, 882 F.3d at 1335
    . And because Leilani’s challenge can’t—for reasons
    we discuss below—“successfully run the gauntlet created by our rigorous plain-error
    standard of review,” we would reject it on the merits. United States v. Rosales-Miranda,
    
    755 F.3d 1253
    , 1258 (10th Cir. 2014) (quoting United States v. Bader, 
    678 F.3d 858
    , 894
    n.24 (10th Cir. 2012)).
    B.     Plain Error
    To succeed under plain-error review, Leilani must establish (1) an error;
    (2) that the error is plain; (3) that the error affected her substantial rights; and (4) that
    the error “seriously affect[ed] the fairness, integrity, or public reputation of judicial
    proceedings.” United States v. Dazey, 
    403 F.3d 1147
    , 1174 (10th Cir. 2005). But “[w]e
    apply plain error ‘less rigidly when reviewing a potential constitutional error,’ which is
    the case here because ‘an improper instruction on an element of the offense violates the
    Sixth Amendment’s jury[-]trial guarantee.’” 
    Benford, 875 F.3d at 1016
    –17 (citation
    omitted) (first quoting United States v. James, 
    257 F.3d 1173
    , 1182 (10th Cir. 2001); then
    quoting Neder v. United States, 
    527 U.S. 1
    , 12 (1999)).
    The government doesn’t dispute that the district court erred in failing to instruct
    the jury that intent is an element of constructive possession. See United States v. Kalu,
    
    791 F.3d 1194
    , 1204 (10th Cir. 2015) (stating that failure to include element of offense in
    jury instruction is error). Nor does the government dispute that the district court’s error
    was plain. See United States v. Taylor, 
    514 F.3d 1092
    , 1100 (10th Cir. 2008) (explaining
    15
    that error is plain if it is “contrary to well-settled law”). Instead, the government argues
    that the error didn’t affect Leilani’s substantial rights.
    To demonstrate that the instructional error affected her substantial rights, Leilani
    must “‘show a reasonable probability that, but for the error,’ the outcome of the
    proceeding would have been different.” Molina-Martinez v. United States, 
    136 S. Ct. 1338
    , 1343 (2016) (quoting United States v. Dominguez Benitez, 
    542 U.S. 74
    , 76 (2004));
    see also 
    Benford, 875 F.3d at 1017
    (explaining that “[a] reasonable probability is a
    probability sufficient to undermine confidence in the outcome” (alteration in original)
    (quoting 
    Wolfname, 835 F.3d at 1222
    )). Here, Leilani argues that the district court’s
    failure to instruct the jury on intent as an element of constructive possession affected the
    outcome of her trial because the evidence supporting that element “was weak at best.”
    Rep. Br. 16. Thus, she asserts, we “cannot have confidence that the jury would have
    found this thin evidence sufficient to prove intent beyond a reasonable doubt” had the
    district court properly instructed it. 
    Id. We recently
    rejected a similar argument in Little, 
    829 F.3d 1177
    . There, we held
    that the district court’s failure to instruct the jury on intent as an element of constructive
    possession constituted harmless error because the evidence supporting that element was
    so “substantial” that any “reasonable jury would be compelled to conclude” the defendant
    “intended to exercise control over the weapons” at issue. 
    Id. at 1183–84.
    In reaching that conclusion, we pointed out that (1) officers found ammunition and
    two stolen firearms—one in a duffle bag on a bed and one under the bed—in a six-by-
    eight structure that the defendant rented; (2) officers discovered the firearms and
    16
    ammunition only seven and a half minutes after the defendant exited the structure; (3) the
    ammunition was in plain sight; (4) the owner of the structure testified that the defendant
    had placed a lock on the structure’s door around the time the firearms were stolen; and
    (5) when the defendant learned the officers had discovered the two firearms, he asked,
    “They only found two?” 
    Id. at 1183.
    Citing the defendant’s “exclusive control” over the small structure and “the seven
    and a half minutes he indisputably spent in it” immediately before the officers discovered
    the firearms and ammunition, some of which was in plain view, we noted that “it would
    be unreasonable to conclude that” the defendant was unaware of their presence. 
    Id. And based
    on this finding, we held there was no reasonable probability that, but for the district
    court’s failure to properly instruct the jury, it “would have found that [the defendant] had
    knowledge of the weapons at issue but lacked intent to exercise control over them.” 
    Id. We recognize
    that the facts in Little differ from the facts before us. Most
    importantly, the defendant in Little exclusively occupied the structure at issue, whereas
    we assume Leilani and Colter jointly occupied both the residence and the bedroom where
    officers discovered the firearm and ammunition. But this distinction doesn’t require us to
    reach a different conclusion. Like the jury in Little, the jury here found that Leilani knew
    about the shotgun and ammunition. And for the reasons we discuss above, 
    see supra
    Part
    I.A., we find ample support for that finding.
    Further, the evidence supporting the omitted intent element is even stronger here
    than it was in Little. Specifically, unlike the jury in Little, the jury in this case had before
    it overwhelming evidence of drug trafficking in the bedroom where the firearm and
    17
    ammunition were found. The government presented evidence that Leilani—a high-level
    drug dealer—sold drugs in the bedroom. The informant also testified that when he
    purchased drugs from Leilani in the bedroom, she reached under the bed and grabbed a
    safe. And on the day of the search, officers found a safe under the bed and drugs, money,
    and a handgun inside the safe. Further, officers located a loaded shotgun, ammunition,
    cash, drug-packaging materials, and large quantities of drugs in the bedroom. And the
    jury heard testimony that drug dealers use firearms for protection. This evidence points to
    the inescapable conclusion that Leilani intended to possess the shotgun and ammunition
    to facilitate her drug distribution. See 
    Johnson, 26 F.3d at 685
    .
    In light of this significant evidence, we conclude there’s no reasonability
    probability that but for the district court’s instructional error, the jury would have
    concluded that Leilani didn’t intend to exercise control over the shotgun and ammunition.
    Thus, because Leilani fails to establish that the instructional error affected her substantial
    rights, she likewise fails to establish plain error. Accordingly, even if we reached
    Leilani’s instructional challenge—which we conclude she waived under the invited-error
    doctrine—we would reject that challenge on the merits.
    III.   Evidentiary Issues
    Next, Leilani raises three evidentiary issues. She asserts that (1) the district
    court erred in admitting certain expert testimony; (2) the district court erred in
    admitting other-acts evidence under Federal Rule of Evidence 404(b); and (3) the
    district court committed additional errors that, although individually harmless,
    require reversal under the cumulative-error doctrine.
    18
    We review for abuse of discretion a district court’s rulings on the admissibility
    of evidence. United States v. Apperson, 
    441 F.3d 1162
    , 1194 (10th Cir. 2006). A
    district court abuses its discretion if its ruling is “arbitrary, capricious, whimsical[,]
    or manifestly unreasonable.” Norris v. Baxter Healthcare Corp., 
    397 F.3d 878
    , 883
    (10th Cir. 2005) (quoting Dodge v. Cotter Corp., 
    328 F.3d 1212
    , 1223 (10th Cir.
    2003)).
    A.     Expert Testimony
    Leilani alleges the district court erred in admitting Detective Brian Roman’s
    expert testimony, in which Roman explained the hierarchy within the drug-trafficking
    world, how drug traffickers use the identities of reputable people to protect product
    or assets, and what “throw phones” are and why drug traffickers use them. R. vol. 3,
    668. Leilani argues (1) Roman’s testimony wasn’t helpful under Federal Rule of
    Evidence 702 and (2) the testimony was unfairly prejudicial under Federal Rule of
    Evidence 403. We reject both arguments.
    1.     Helpfulness to the Jury
    Under Rule 702, an expert’s testimony must help the jury to “understand the
    evidence or to determine a fact in issue.” Fed. R. Evid. 702(a). In determining
    whether testimony is helpful, we employ “a common-sense inquiry” that asks
    “whether a juror would be able to understand the evidence without specialized
    knowledge concerning the subject.” United States v. McDonald, 
    933 F.2d 1519
    , 1522
    (10th Cir. 1991).
    19
    Leilani first argues that Roman’s testimony wasn’t helpful because the jury
    could have understood the evidence before it without specialized knowledge or
    training. But “we have long recognized that police officers can testify as experts
    based on their experience ‘[b]ecause the average juror is often innocent of the ways
    of the criminal underworld.’” United States v. Kamahele, 
    748 F.3d 984
    , 998 (10th
    Cir. 2014) (alteration in original) (quoting United States v. Garcia, 
    635 F.3d 472
    , 477
    (10th Cir. 2011)). Thus, Roman’s testimony aided the jury in understanding the
    intricacies of drug trafficking and in contextualizing the evidence already before it.
    Leilani also contends Roman’s testimony wasn’t helpful because he failed to
    specifically identify the firearm at issue and tie that firearm to drug trafficking. The
    record belies this argument. Roman described the features of the shotgun, including
    its “pistol grip” and “extended tube.” R., vol. 3, 670. And after discussing the
    differences between firearms designed for tactical use and those used for sport,
    Roman testified that the shotgun at issue here is “clear[ly a] tactical firearm” because
    of the pistol grip and extended tube. 
    Id. Thus, Roman’s
    testimony helped the jury
    differentiate between various types of firearms and infer that the shotgun in this case
    wasn’t used for sport. The jury could further extrapolate that Leilani used the shotgun
    in furtherance of drug trafficking.
    Next, Leilani argues that Roman’s testimony wasn’t probative of any fact of
    consequence in this case. Specifically, she asserts that Roman testified only about
    generalities of the drug trade—e.g., tools of the drug trade—without connecting any
    of these generalities to the facts in this case. Therefore, according to Leilani,
    20
    Roman’s testimony would not have helped the jury decide whether she sold drugs.
    We think otherwise.
    Whether Leilani sold drugs is a fact of consequence in this case. And even
    though Roman’s testimony didn’t expressly link Leilani to drug trafficking, his
    testimony contextualized the evidence already presented in a manner that allowed the
    jury to infer that Leilani was a drug trafficker. See United States v. Medina-Copete,
    
    757 F.3d 1092
    , 1106 (10th Cir. 2014) (finding expert testimony relevant because it
    “contextualized the evidence that the jury had already seen”). For example, evidence
    at trial showed that investigators found a digital scale in the living room, and Roman
    testified that drug dealers often use digital scales to weigh specific quantities of
    drugs.
    Because Roman’s testimony was probative and helpful, the district court didn’t
    abuse its discretion in admitting that testimony under Rule 702.
    2.     Unfair Prejudice
    Leilani also challenges Roman’s testimony under Rule 403, which permits a
    district court to “exclude relevant evidence if its probative value is substantially
    outweighed by a danger of . . . unfair prejudice.” Fed. R. Evid. 403.
    Leilani’s argument on this point is unclear. She asserts that Roman’s testimony
    “created an emotional reaction [among the jurors] that [she] was a mid-level drug
    dealer,” Aplt. Br. 42, but she fails to provide any support or explanation for this
    assertion. Likewise, she fails to explain how such an “emotional reaction” might have
    been so unfairly prejudicial as to outweigh the probative value of Roman’s testimony.
    21
    
    Id. And we
    don’t see how it would have been. We therefore conclude the district
    court acted within its broad discretion in admitting Roman’s expert testimony under
    Rule 403. See United States v. Cherry, 
    433 F.3d 698
    , 702 (10th Cir. 2005) (“We
    afford district courts ‘broad discretion in making rulings under Rule 403.’” (quoting
    United States v. Ramirez, 
    63 F.3d 937
    , 943 (10th Cir. 1995))).
    B.     Other-Acts Evidence
    Next, Leilani argues that the district court erred by admitting other-acts
    evidence. Evidence of other acts is inadmissible “to prove a person’s character in order
    to show that on a particular occasion the person acted in accordance with the character.”
    Fed. R. Evid. 404(b)(1). But such evidence may be offered for a proper purpose,
    including showing knowledge, opportunity, intent, or absence of mistake. 
    Id. 404(b)(2). In
    addition to being offered for a proper purpose, the evidence must be relevant and the
    danger of unfair prejudice must not substantially outweigh the evidence’s probative
    value. See Huddleston v. United States, 
    485 U.S. 681
    , 691 (1988). Finally, “the [district]
    court shall, upon request, instruct the jury that the [other-]acts evidence is to be
    considered only for the proper purpose for which it was admitted”. 
    Id. at 691–92.
    Here, the government introduced evidence of Leilani’s drug-related activity
    through the testimony of Detective Sincerbox and the informant. The evidence included
    testimony about (1) the first controlled purchase between the informant and Leilani; (2) a
    suspected hand-to-hand drug transaction between Leilani and a third party, which
    Sincerbox observed within three months of the search warrant’s execution; and
    (3) several individuals whom Sincerbox observed entering Leilani’s residence and
    22
    leaving within a short period of time, fewer than 72 hours before the second controlled
    purchase.
    The government offered the prior-purchase evidence to show Leilani’s knowledge
    of drug trafficking and that she purposely sold drugs. And it offered the other evidence to
    show her knowledge of drug trafficking and her opportunities to sell drugs. The district
    court admitted the evidence but issued a limiting instruction at Leilani’s request. On
    appeal, Leilani contends the evidence was irrelevant and the danger of unfair prejudice
    substantially outweighed its minimal probative value. This argument fails for two
    reasons.
    First, the other-acts evidence was relevant. The government charged Leilani with
    distributing and possessing with the intent to distribute a controlled substance. See
    § 841(a)(1). Under these circumstances, the government was required to prove beyond a
    reasonable doubt that Leilani knowingly and intentionally distributed or possessed with
    the intent to distribute a controlled substance. See 
    id. (stating that
    it’s “unlawful for any
    person [to] knowingly or intentionally . . . distribute, or dispense, or possess with intent to
    manufacture, distribute, or dispense, a controlled substance”) (emphasis added); United
    States v. Carter, 
    130 F.3d 1432
    , 1440 (10th Cir. 1997) (explaining that § 841(a)(1)
    requires government to prove “(1) the defendant knowingly possessed the illegal drug;
    and (2) the defendant possessed the drug with the specific intent to distribute it”
    (quoting United States v. Reece, 
    86 F.3d 994
    , 996 (10th Cir. 1996))). And under Rule
    404(b), other-acts evidence is relevant to show a person’s knowledge and intent if the
    other acts are similar and temporally proximate to the crimes charged. See United States
    23
    v. Cardinas Garcia, 
    596 F.3d 788
    , 797–98 (10th Cir. 2010) (explaining that “[t]o
    determine relevance under Rule 404(b), we must examine factors such as the similarity of
    the uncharged act to the charged conduct and the temporal proximity of the two acts”);
    United States v. Watson, 
    766 F.3d 1219
    , 1239 (10th Cir. 2014) (stating “that prior
    narcotics involvement is relevant when that conduct is close in time, highly probative,
    and similar to the activity with which the defendant is charged” (quoting United States v.
    Becker, 
    230 F.3d 1224
    , 1232 (10th Cir. 2000))).
    Here, the other-acts evidence wasn’t too remote because all the prior drug-related
    activity occurred within three months of Leilani’s arrest. See, e.g., United States v.
    Mares, 
    441 F.3d 1152
    , 1159 (10th Cir. 2006) (finding that evidence demonstrating
    defendant engaged in similar conduct one year before charged conduct was relevant).
    And the other-acts evidence concerned the same conduct and types of drugs as those
    charged in the indictment, making it highly probative of the fact that Leilani knew she
    was selling drugs and intended to do so. See 
    Watson, 766 F.3d at 1237
    . Thus, we find this
    other-acts evidence relevant to show that when Leilani sold drugs to the informant during
    the second controlled purchase, she did so knowingly and intentionally.
    Next, the evidence’s probative value wasn’t substantially outweighed by the
    danger of unfair prejudice. Leilani argues that the evidence portrayed her as a person with
    the character of a drug dealer who—the jury could have concluded—acted in conformity
    with that character by distributing heroin. And she contends that the district court’s
    limiting instruction failed to explicitly prohibit the jury from using the evidence to prove
    she had a propensity to distribute drugs.
    24
    The district court informed the jury,
    You may consider this [other-acts] evidence only as it bears on [Leilani’s]
    knowledge, or lack of knowledge of the drug[-]trafficking business,
    whether she had the opportunity to sell drugs or lack of mistake and for no
    other purpose. Of course the fact that [Leilani] is alleged to have
    committed an act that is not charged in the [i]ndictment does not mean that
    she necessarily committed the acts charged in this case.
    R. vol. 3, 755 (emphasis added). Although the district court’s limiting instruction
    isn’t an exercise in precision, it did very clearly limit the purposes for which the jury
    could consider the other-acts evidence. Thus, we conclude the probative value of the
    other-acts evidence wasn’t substantially outweighed by any risk of unfair prejudice
    and the district court didn’t abuse its discretion in admitting the other-acts evidence
    under Rule 404(b).
    C.     Cumulative Error
    In addition to the evidentiary errors alleged above, Leilani argues that the
    government engaged in impermissible witness vouching and that the district court
    incorrectly admitted testimony that amounted to impermissible hearsay. She concedes
    that these errors were individually harmless, but she maintains that their cumulative
    effect requires reversal. See United States v. Rivera, 
    900 F.2d 1462
    , 1470 (10th Cir.
    1990) (“A cumulative-error analysis . . . aggregates all the errors that individually
    have been found to be harmless, and therefore not reversible, and it analyzes whether
    their cumulative effect on the outcome of the trial is such that collectively they can
    no longer be determined to be harmless.”).
    25
    Leilani argues that Sincerbox improperly vouched for the informant’s
    credibility in violation of Federal Rule of Evidence 608(a). But she didn’t raise this
    objection below and doesn’t argue for plain-error review in her opening brief.
    Therefore, the government contends that Leilani has waived this specific challenge.
    See Richison v. Ernest Grp., Inc., 
    634 F.3d 1123
    , 1131 (10th Cir. 2011) (“[T]he
    failure to argue for plain error and its application on appeal . . . marks the end of the
    road for an argument for reversal not first presented to the district court.”).
    Notably, Leilani doesn’t respond to the government’s waiver assertion in her
    reply brief. Nor does she advance a plain-error argument there. Thus, we find her
    vouching challenge waived and decline to consider it. See In re FCC 11–161, 
    753 F.3d 1015
    , 1100–01 (10th Cir. 2014) (rejecting appellant’s argument because
    appellant “ma[d]e no attempt” in reply brief “to rebut” appellee’s response to that
    argument); cf. Hardy v. City Optical Inc., 
    39 F.3d 765
    , 771 (7th Cir. 1994) (noting
    that “[w]hen an appellee advances an alternative ground for upholding a ruling by the
    district judge, and the appellant does not respond in his reply brief or at argument,”
    appellant “waives, as a practical matter anyway, any objections not obvious to the
    court to specific points urged by the appellee”). And because Leilani has waived any
    challenge to the alleged vouching error, we refrain from undertaking a cumulative-
    error analysis; Leilani only alleges one additional evidentiary error, which she
    concedes is harmless on its own. See United States v. Franklin-El, 
    555 F.3d 1115
    ,
    1128 (10th Cir. 2009) (refraining from engaging in a cumulative-error analysis
    because defendant didn’t establish multiple errors).
    26
    Conclusion
    We conclude the government presented sufficient evidence to support Leilani’s
    convictions for possessing the shotgun and ammunition under § 922(g)(1) and for
    possessing the shotgun in furtherance of a drug-trafficking crime under
    § 924(c)(1)(A). And although we agree with Leilani that the district court erred in
    failing to instruct the jury on intent as an element of construction possession, we
    decline to reverse on this basis because Leilani invited the instructional error below.
    Further, even if we overlooked this affirmative waiver, the instructional error doesn’t
    survive plain-error review.
    Additionally, we hold that the district court didn’t abuse its discretion by
    admitting Roman’s expert testimony or the other-acts evidence. And we determine
    that we are precluded from conducting a cumulative-error analysis. Finally, we deny
    as moot the government’s motion to supplement the record on appeal because the
    supplementary materials don’t affect our analysis. See United States v. Rivas-Macias,
    
    537 F.3d 1271
    , 1282 n.16 (10th Cir. 2008).
