    Defendant Francisco Cantu, Jr. appeals the enhancement of his sentence under the
    Armed Career Criminal Act (ACCA), 
    18 U.S.C. § 924
    (e)(1). Although he failed to
    preserve his challenge to the enhancement in district court, the enhancement was plainly
    contrary to the law of this circuit. Exercising jurisdiction under 
    18 U.S.C. § 3742
    (a) and
    
    28 U.S.C. § 1291
    , we vacate his sentence and remand for resentencing.
    The ACCA enhancement rested in part on the characterization of Defendant’s two
    prior convictions for drug offenses under 
    Okla. Stat. tit. 63, § 2
    –401(A)(1) as “serious
    drug offenses.” But there are multiple means by which the Oklahoma statute can be
    violated, and some of those means do not satisfy the ACCA definition of serious drug
    offense. Under the categorical/modified-categorical approach established by the United
    States Supreme Court for determining whether a state conviction can qualify as an ACCA
    predicate conviction, the two state convictions therefore cannot be predicate convictions
    supporting an ACCA enhancement.
    After describing the proceedings against Defendant, we summarize the relevant
    law under the ACCA, apply that law to Defendant’s prior state drug convictions, and then
    consider whether relief is proper even though Defendant did not preserve the issue in
    district court.
    I.         BACKGROUND
    In 2019 Defendant pleaded guilty to being a felon in possession of a firearm. See
    
    18 U.S.C. § 922
    (g). The presentence report (PSR) said that he was subject to an
    enhancement under the ACCA based on three prior Oklahoma convictions: (1) unlawful
    possession of a controlled drug with intent to distribute on August 21, 2008, (2)
    distribution of methamphetamine on December 13, 2010, and (3) distribution of
    methamphetamine on December 27, 2010. Defendant was convicted of the latter two
    state offenses on March 6, 2012, after pleas of nolo contendere. During sentencing for
    2
    his federal offense he did not object to his PSR, nor did he file a sentencing
    memorandum. The district court adopted the PSR and sentenced him to a prison term of
    210 months, which was the bottom of the advisory sentencing guidelines range. Without
    the ACCA enhancement his maximum prison term would have been 120 months. See 
    18 U.S.C. § 924
    (a)(2).
    II.    THE ACCA
    The ACCA increases the penalty for being a felon in possession of a firearm for
    any person who has “three previous convictions . . . for a violent felony or a serious drug
    offense.” 
    18 U.S.C. § 924
    (e)(1). Our concern in this appeal relates only to serious drug
    offenses. The statutory definition of serious drug offense includes “an offense under
    State law, involving manufacturing, distributing, or possessing with intent to manufacture
    or distribute, a controlled substance (as defined in section 102 of the Controlled
    Substances Act (
    21 U.S.C. § 802
    )), for which a maximum term of imprisonment of ten
    years or more is prescribed by law.” 
    18 U.S.C. § 924
    (e)(2)(A)(ii). The incorporated
    definition of controlled substance is “a drug or other substance, or immediate precursor,
    included in schedule I, II, III, IV, or V of part B of this subchapter [21 U.S.C §§ 811–
    14].” 
    21 U.S.C. § 802
    (6).
    To determine whether a state conviction was for a serious drug offense, we
    generally begin with the categorical approach. See United States v. Smith, 
    652 F.3d 1244
    , 1246 (10th Cir. 2011) (categorical approach applies to both violent felonies and
    serious drug offenses). There are two key features of this approach. First, the court looks
    only to the elements of the state offense. The particular facts of the defendant’s prior
    3
    offense are irrelevant. All that counts is what the defendant had to do to be guilty of the
    offense. See Mathis v. United States, 
    136 S. Ct. 2243
    , 2248 (2016). Second, it is not
    enough that there is an overlap between the elements of the state offense and the
    definition of serious drug offense. It is necessary that essentially any conduct that
    satisfies the elements of the state offense also satisfy the definition of serious drug
    offense. If one can commit the state offense by conduct that is not a serious drug offense,
    then conviction of the state offense cannot be a predicate offense for the ACCA. See 
    id.
    The Supreme Court recently illustrated these two points in Mellouli v. Lynch, 
    135 S. Ct. 1980
    , 1983–84 (2015), where it applied the categorical approach to a provision in
    the Immigration and Nationality Act authorizing the removal of an alien convicted of
    violating a state law “relating to a controlled substance (as defined in section 802 of Title
    21),” 8 U.S.C § 1227(a)(2)(B)(i). Mr. Mellouli had been convicted in Kansas of violating
    a state law prohibiting possession of drug paraphernalia to store or conceal a substance
    that was a controlled substance as defined by state law. See Mellouli, 
    135 S. Ct. at 1983
    .
    The controlled substance involved in the offense was Adderall, which is also a controlled
    substance under federal law. See 
    id. at 1985
    . What mattered for purposes of the
    categorical approach, however, was not the specific substance involved in Mellouli’s
    offense but (1) the fact that the Kansas statute could be violated with any controlled
    substance under Kansas law and (2) the Kansas statute of conviction “was not confined to
    federally controlled substances,” because “Kansas’ schedules of controlled substances
    included at least nine substances—e.g., salvia and jimson weed—not defined in § 802.”
    Id. at 1988. The Court rejected the government’s argument that state drug offenses can
    4
    qualify as serious drug offenses if the state schedules have a “substantial overlap” with
    the federal schedules. Id. at 1990 (internal quotation marks omitted). “In short, the state
    law under which [Mr. Mellouli] was charged categorically related to a controlled
    substance, but was not limited to substances defined in § 802.” Id. at 1988 (original
    brackets and internal quotation marks omitted). Thus, “[u]nder the categorical approach
    . . . [Mr.] Mellouli’s drug-paraphernalia conviction d[id] not render him deportable.” Id.
    Because the government did not argue otherwise, see id. at 1986 n.4, the Supreme
    Court in Mellouli treated the Kansas statute as stating a single criminal offense, which
    could be violated in a number of alternative ways, depending on what controlled
    substance was involved. But sometimes the alternatives (say, each controlled substance)
    in a statute define distinct criminal offenses. We then say that the statute is divisible and
    apply the modified-categorical approach, in which the categorical approach is applied
    separately to the relevant sub-crime within the statute. See Mathis, 136 S. Ct. at 2249. A
    court can ascertain which sub-crime the defendant was convicted of by examining a
    limited category of court records, such as the charging document, jury instructions, a plea
    agreement, or a plea colloquy. See id.
    To determine whether a statute is divisible, it is essential to distinguish between
    elements and means. “Elements are the constituent parts of a crime’s legal definition—
    the things the prosecution must prove to sustain a conviction.” Id. at 2248 (internal
    quotation marks omitted). They are what the jury must unanimously find beyond a
    reasonable doubt to render a guilty verdict, and what a defendant must admit when
    pleading guilty. See id. Means, in contrast, “spell[] out various factual ways of
    5
    committing some component of the offense—a jury need not find (or a defendant admit)
    any particular item.” Id. at 2249. For example, a statute may have as an element the use
    of a “deadly weapon” and “further provide[] that the use of a ‘knife, gun, bat, or similar
    weapon’ would all qualify [as means].” Id. at 2249 (further internal quotation marks
    omitted). A jury could convict even if half believed the defendant used a knife and the
    other half thought he used a gun, so long as there was unanimity on the relevant
    element—namely, that he used a “deadly weapon.” See id.; United States v. Degeare,
    
    884 F.3d 1241
    , 1251–52 (10th Cir. 2018) (noting that “Mathis makes jury unanimity the
    touchstone of the means-or-elements inquiry” and that “we have likewise adopted a
    unanimity-focused approach to the means-or-elements question”).
    With this background we now examine Defendant’s state drug convictions to see
    whether they qualify as serious drug offenses.
    III.   APPLICATION TO DEFENDANT’S CONVICTIONS
    A.     Divisibility of § 2–401(A)(1)
    Defendant’s 2012 convictions were for violations of an Oklahoma statute that
    made it unlawful “[t]o distribute, dispense, transport with intent to distribute or dispense,
    possess with intent to manufacture, distribute, or dispense, a controlled dangerous
    substance or to solicit the use of or use the services of a person less than eighteen (18)
    years of age to cultivate, distribute or dispense a controlled dangerous substance.” 
    Okla. Stat. Ann. tit. 63, § 2
    –401(A)(1) (West 2011). Controlled dangerous substance is
    defined by Oklahoma as “a drug, substance or immediate precursor in Schedules I
    through V of the [Oklahoma] Uniform Controlled Dangerous Substances Act.” 
    Id.
     § 2–
    6
    101(8). It is undisputed that in December 2010, when Defendant committed the two state
    offenses at issue here, at least three substances (e.g., salvinorin A) that satisfied this
    definition were not controlled substances under federal law. Compare 
    Okla. Stat. Ann. tit. 63, § 2
    –204(C) (West Supp. 2010), with 
    21 C.F.R. §§ 1308.11
    –15 (2019). Therefore,
    under the categorical approach Defendant’s convictions under § 2–401(A)(1) were not
    convictions for serious drug offenses under the ACCA. See Melllouli, 
    135 S. Ct. at 1988
    .
    The government argues, however, that the Oklahoma statute is divisible based on
    each individual drug listed in Oklahoma’s drug schedules and that Defendant was
    convicted of offenses involving methamphetamine. Since methamphetamine is a federal
    controlled substance, see 
    21 C.F.R. § 1308.12
     (2019), Defendant’s state convictions
    would be for serious drug offenses.
    The principal issue on appeal thus is whether the state statute is divisible, with a
    violation for each controlled substance being a distinct offense. To help us answer the
    question, the Supreme Court has set forth a framework for analysis. First, we should
    begin by examining “authoritative sources of state law,” including the statute on its face
    and state-court decisions. Mathis, 136 S. Ct. at 2256. If, for example, “a state court
    decision definitively answers the question, . . . a sentencing judge need only follow what
    it says.” Id. Next, “if state law fails to provide clear answers, federal judges have
    another place to look: the record of a prior conviction itself.” Id. For example, “an
    indictment and jury instructions could indicate, by referencing one alternative term to the
    exclusion of all others, that the statute contains a list of elements, each one of which goes
    toward a separate crime.” Id. at 2257 (“Of course, such record materials will not in every
    7
    case speak plainly. . . .”). If, however, we cannot ultimately say with certainty that the
    statute is divisible, we will not apply the modified-categorical approach. See Degeare,
    884 F.3d at 1248 (“[U]nless we are certain that a statute’s alternatives are elements rather
    than means, the statute isn’t divisible and we must eschew the modified categorical
    approach.”).
    Federal courts have interpreted statutes similar to Oklahoma’s on a number of
    occasions and have relied on state-court authority to determine divisibility, although the
    authorities in different states point in different directions. See Cucalon v. Barr, 
    958 F.3d 245
    , 253 (4th Cir. 2020) (collecting cases). Here, too, a state-court decision provides the
    answer to divisibility. Before discussing the decision, however, we should say a little
    more about the Oklahoma statutory scheme. Section 2–401(A)(1) did not distinguish
    among the various substances defined as controlled dangerous substances by Oklahoma
    law. But the penalties were not the same for every drug offense. Section 2–401(B)
    introduced the penalty provisions with: “Any person who violates the provisions of this
    section with respect to” and then set different penalties for three different categories of
    controlled dangerous substances. See 
    Okla. Stat. Ann. tit. 63, § 2
    –401(B)(1) (West 2011)
    (punishing offenses involving Schedule I or II narcotic drugs, LSD, or one of five other
    substances related to gamma hydroxybutyrate (GHB) with a “term of imprisonment for
    not less than five (5) years nor more than life”); 1 
    id.
     § 2–401(B)(2) (punishing offenses
    1
    Paragraph (B)(1) stated:
    8
    involving any other Schedule I, II, III, or IV drug with a “term of imprisonment for not
    less than two (2) years nor more than life”); 2 id. § 2–401(B)(3) (punishing offenses
    involving Schedule V drugs with “a term of imprisonment for not more than five (5)
    years”). 3
    [Any person who violates the provisions of § 2–401(A) with respect to] [a]
    substance classified in Schedule I or II which is a narcotic drug, lysergic
    acid diethylamide (LSD), gamma butyrolactone, gamma hydroxyvalerate,
    gamma valerolactone, 1,4 butanediol, or gamma-hydroxybutyric acid as
    defined in Sections 2–204 and 2–208 of this title, upon conviction, shall be
    guilty of a felony and shall be sentenced to a term of imprisonment for not
    less than five (5) years nor more than life and a fine of not more than One
    Hundred Thousand Dollars ($100,000.00), which shall be in addition to
    other punishment provided by law and shall not be imposed in lieu of other
    punishment. Any sentence to the custody of the Department of Corrections
    shall not be subject to statutory provisions for suspended sentences,
    deferred sentences, or probation except when the conviction is for a first
    offense[.]
    
    Okla. Stat. Ann. tit. 63, § 2
    –401(B)(1) (West 2011).
    2
    Paragraph (B)(2) stated:
    [Any person who violates the provisions of § 2–401(A) with respect to]

    or IV, upon conviction, shall be guilty of a felony and shall be sentenced to
    a term of imprisonment for not less than two (2) years nor more than life
    and a fine of not more than Twenty Thousand Dollars ($20,000.00), which
    shall be in addition to other punishment provided by law and shall not be
    imposed in lieu of other punishment. Any sentence to the custody of the
    Department of Corrections shall not be subject to statutory provisions for
    suspended sentences, deferred sentences, or probation except when the
    conviction is for a first offense[.]
    
    Okla. Stat. Ann. tit. 63, § 2
    –401(B)(2) (West 2011).
    3
    Paragraph (B)(3) stated:
    9
    In our view, Oklahoma case law makes it impossible to say with certainty that the
    Oklahoma statute is divisible by individual drug. The leading opinion on the point is
    Watkins v. State, 
    855 P.2d 141
     (Okla. Crim. App. 1992). The defendant had been
    convicted on one count of possession with intent to distribute cocaine and one count of
    intent to distribute phencyclidine (PCP) based on his shipping both substances in a single
    package. See 
    id. at 141
    . The Oklahoma Court of Criminal Appeals (OCCA) determined
    that the defendant had committed only one violation of § 2–401 and could not be
    sentenced separately for two offenses. See id. at 142. It rejected the argument that there
    were “two separate offenses with different elements requiring different ranges of
    punishment”; “Possession with Intent to Distribute is a single offense under Section 2-
    401. Part A of Section 2-401 sets forth the substantive offense while Part B sets forth the
    parameters of punishment based on the type of drug involved.” Id. The court
    acknowledged that “different punishment levels are provided for different drugs,” but
    said that the State’s “argument does not take into consideration the statutory language of
    Section 2–401(A)(1) which is the substantive criminal prohibition, i.e., it is unlawful for
    any person to possess with the intent to distribute ‘a controlled dangerous substance.’”
    Id. In short, “[t]he statutory prohibition does not distinguish between types or
    [Any person who violates the provisions of § 2–401(A) with respect to] [a]
    substance classified in Schedule V, upon conviction, shall be guilty of a
    felony and shall be sentenced to a term of imprisonment for not more than
    five (5) years and a fine of not more than One Thousand Dollars
    ($1,000.00), which shall be in addition to other punishment provided by
    law and shall not be imposed in lieu of other punishment[.]
    
    Okla. Stat. Ann. tit. 63, § 2
    –401(B)(3) (West 2011).
    10
    classifications of drugs.” 
    Id.
     It explained, “While we recognize the Oklahoma
    Legislature has the power to create separate penal provisions prohibiting different acts
    which may be committed at the same time, it was not exercised in the passage of the
    provisions of Section 2–401(A)(1) as this statute applies to a ‘controlled dangerous
    substance.’” 
    Id.
     Because the “elements of each count . . . were the same,” double-
    jeopardy doctrine prohibited the defendant’s multiple punishments for the same offense.
    
    Id. at 142
    . The court’s language at the very least is potent support for the proposition that
    the alternative ways in which the statutory violation can be committed (by distributing
    any one of a number of controlled substances) are alternative means, rather than
    alternative elements.
    This and other courts have held that decisions like Watkins resolve the divisibility
    question. See United States v. McKibbon, 
    878 F.3d 967
    , 975 (10th Cir. 2017) (Colorado
    Supreme Court double-jeopardy decision that defendant could not be convicted of both
    possession and distribution “addresses exactly th[e] question” of whether statute was
    divisible); United States v. Garcia, 
    948 F.3d 789
    , 794 (7th Cir. 2020) (considering an
    Indiana intermediate-court case that held “possessing marijuana and hashish is only one
    violation” to be “the authoritative resolution” of the divisibility issue); Martinez v.
    Sessions, 
    893 F.3d 1067
    , 1071 (8th Cir. 2018) (concluding that Missouri double-jeopardy
    court decisions show that each controlled substance is an element); see also Najera-
    Rodriguez v. Barr, 
    926 F.3d 343
    , 352–353 (7th Cir. 2019) (interpreting Illinois case
    describing element as a “controlled substance” to “signal[]” that “identity of the
    controlled substance is not an element”). But see United States v. Burris, 
    912 F.3d 386
    ,
    11
    403–04 (6th Cir. 2019) (en banc), cert. denied, 
    140 S. Ct. 90
     (2019) (interpreting Ohio
    law as treating felonious assault and aggravated assault as distinct crimes even though a
    separate state statute prohibits punishment under both statutes for a “single act
    undertaken with a single animus” as a matter of legislative intent because they are “allied
    offenses of similar import” (internal quotation marks omitted)).
    The government points out, however, that Watkins recognized that punishment for
    violations of § 2–401(A)(1) is “based on the type of drug involved,” Watkins, 855 P.2d at
    142, and that in light of United States Supreme Court authority postdating Watkins, the
    statute must therefore be divisible. There is much truth in what the government says, but
    it does not affect our conclusion. First, the government is correct that the Oklahoma
    punishment for offenses involving controlled dangerous substances depends on the
    substance. We have already noted that § 2–401(B) divides substances into three
    categories with different maximum sentences. Second, it is true that after Watkins was
    decided the Supreme Court held that “[o]ther than the fact of a prior conviction, any fact
    that increases the penalty for a crime beyond the prescribed statutory maximum must be
    submitted to a jury, and proved beyond a reasonable doubt.” Apprendi v. New Jersey,
    
    530 U.S. 466
    , 490 (2000). In other words, a fact that must be proved to increase the
    penalty is an element of the offense. See Mathis, 136 S. Ct. at 2256 (“If statutory
    alternatives carry different punishments, then under Apprendi they must be elements.”).
    Thus, the category to which an Oklahoma controlled dangerous substance belongs is an
    element of a violation of § 2–401(A)(1). And third, because different offenses under § 2–
    401(A)(1) have different elements, the statute must be divisible. See United States v.
    12
    Maldonado-Palma, 
    839 F.3d 1244
    , 1247 (10th Cir. 2016) (“New Mexico’s aggravated
    assault statute is a divisible statute because it sets out alternative elements for aggravated
    assault in three subsections.”).
    That syllogism, however, does not take the government far enough to prevail in
    this case. It is not as if the penalty is different for each controlled dangerous substance.
    Those substances are divided into only three categories for purposes of punishment.
    Therefore, § 2–401(A)(1) is divisible based on those three categories. But any further
    division into individual substances appears inconsistent with Watkins. It effectively held
    that the jury did not need to agree on which controlled dangerous substance was involved
    in the defendant’s crime. From Apprendi we now know that the jury must agree on
    which category the substance belongs to. But Apprendi still leaves to Oklahoma to
    determine whether juries must agree on which substance within a category was involved.
    Although the precise holding in Watkins is incorrect because cocaine and PCP were in
    different categories for sentencing purposes, the language in Watkins appears inconsistent
    with the notion that now, in light of Apprendi, the specific controlled dangerous
    substance is an element of § 2–401(A)(1). Indeed, just last year the OCCA, agreeing
    with a concession by the State, held that a defendant could not be convicted of both
    unlawful possession with intent to distribute cocaine and unlawful possession with intent
    to distribute methamphetamine (which belong to the same category for sentencing) when
    both drugs were found in the same receptacle. See Alexander v. State, 
    449 P.3d 860
    , 868
    (Okla. Crim. App. 2019) (“Based on Watkins, we must vacate Count 2 . . . .”); 
    id. at 871
    (Lumpkin, J., concurring in part and dissenting in part) (continuing to apply Watkins
    13
    since “the Oklahoma Legislature failed to set out that possession of each separate drug
    constitutes a separate offense and is punishable individually” and the “Legislature has
    had a substantial amount of time to correct the drafting and by its silence has elected not
    to do so”). We need add only that methamphetamine, the drug involved in Defendant’s
    state prosecutions, is in the same category of drugs as three Oklahoma controlled
    dangerous drugs that have not been controlled substances under federal law. (We express
    no view on whether a defendant’s conviction would qualify as a conviction for a serious
    drug offense under the ACCA if the sentence had been imposed under § 2–401(B)(1) or
    (B)(3).)
    Although we consider Watkins dispositive, we also address three arguments made
    by the government based on other state-law sources. None is persuasive.
    First, the government relies on the Oklahoma Uniform Jury Instruction for
    Defendant’s offenses, 4 which at the time of his conviction provided:
    No person may be convicted of distributing a controlled dangerous substance
    unless the State has proved beyond a reasonable doubt each element of the
    crime. These elements are:
    First, knowingly/intentionally,
    Second, distributing/(transporting with the intent to
    distribute)/[soliciting the use]/[using the services] of a person less
    4
    Mathis speaks of examining the jury instructions as part of the record of conviction that
    may be turned to when state-law sources do not provide clear answers on the issue of
    divisibility. See 136 S. Ct. at 2256–57. This court has gone beyond that limited use and
    has also analyzed a state’s uniform jury instructions as a potential source of state law
    even when a defendant pleads guilty. See Titties, 852 F.3d at 1270 n.15, 1271 (“[W]here
    the defendant pled guilty and no jury instructions were given, the state’s uniform jury
    instructions can provide insight into the means/elements question.”).
    14
    than 18 year of age to cultivate/distribute/ manufacture/(attempt to
    manufacture);
    Third, the controlled substance of [Name of Substance].
    Okla. Unif. Jury Instr. CR (2d) 6–2 (bold lettering omitted). The government contends
    that because the third element is singular the instruction clearly indicates that only one
    substance can be inserted, which in turn shows that the individual drug is an element.
    If the jury instruction or a usage note with the instruction expressly required that
    only one substance be stated in the instruction on the third element, the government
    would have a better argument, even though Oklahoma jury instructions are not treated as
    definitive, see Mitchell v. State, 
    387 P.3d 934
    , 943 (Okla. Crim. App. 2016) (“Trial courts
    should use the uniform jury instructions if they state the applicable law.” (emphasis
    added)); 
    Okla. Stat. Ann. tit. 12, § 577.2
     (“Whenever Oklahoma Uniform Jury
    Instructions (OUJI) contains an instruction applicable in a civil case or a criminal case,
    giving due consideration to the facts and the prevailing law, and the court determines that
    the jury should be instructed on the subject, the OUJI instructions shall be used unless the
    court determines that it does not accurately state the law.”). But as the uniform
    instruction is written, we think it does not confront the particular question of whether
    multiple substances could be treated as alternative means in the third element. We note
    that circuit courts have generally refused to treat such “singular” language in itself as
    establishing that every alternative that could be placed in the template is an element of
    the offense. See, e.g., Jimenez v. Sessions, 
    893 F.3d 704
    , 714 n.4 (10th Cir. 2018) (“[W]e
    are not persuaded that Colorado’s pattern jury instructions shed much light on the
    15
    question before us. The first-degree-trespass instruction includes a space for courts to
    insert the name of the ulterior offense . . . . But the pattern instruction does not tell us
    whether a jury would have to reach a unanimous determination if multiple ulterior
    offenses are at issue.”); Martinez, 893 F.3d at 1072 (“Whether means or element, the
    identity of a controlled substance will be inserted to complete the [Missouri approved
    jury] instructions when the charge involves a substance other than marijuana. But we
    must look elsewhere to understand whether the name of the controlled substance
    describes an element of the offense.”); Harbin v. Sessions, 
    860 F.3d 58
    , 68 (2d Cir. 2017)
    (“Although the [New York pattern jury instructions] include a blank with the word
    ‘specify’ in it, allowing a judge to name the substances at issue in the case, the
    instructions do not say it is impermissible to identify more than one substance. No rule
    of law or language requires that the term ‘specify’ cover only one object.”). But cf.
    Guillen v. U.S. Att’y Gen., 
    910 F.3d 1174
    , 1184 (11th Cir. 2018) (divisibility indicated by
    jury instructions requiring entry of “(specific substance)” and state intermediate appellate
    court’s citing instructions as setting out elements of the drug offense). Similarly, even if
    we were to turn to the records of Defendant’s prior convictions, we would attach little
    weight to the fact that the charging documents for Defendant’s two methamphetamine
    convictions explicitly mention methamphetamine rather than just charging him with
    distribution of a substance described in § 2–401(B)(2). The prosecution had no occasion
    to consider how to charge the joint distribution of two substances.
    We address summarily the government’s remaining two arguments, largely
    because their logic escapes us. One argument is that the penalty sections of § 2–401
    16
    indicate divisibility because they refer not only to drug schedules but to specific drugs.
    Recall that § 2–401(B)(1) sets the penalty for any “substance classified in Schedule I or II
    which is a narcotic drug, lysergic acid diethylamide (LSD),” or which is one of five other
    substances related to GHB. 
    Okla. Stat. Ann. tit. 63, § 2
    –401(B)(1) (West 2011). But we
    fail to see how it is of any moment how Oklahoma decided to define any specific group
    of drugs for purposes of punishment—whether in lockstep with the statutory schedules,
    or by picking and choosing among the schedules. The important thing is that the separate
    paragraphs of § 2–401(B) make § 2–401(A)(1) divisible into groups based on the penalty
    imposed because of the Supreme Court’s decision in Apprendi, but any further
    divisibility would be inconsistent with the OCCA’s decision in Watkins.
    The government’s other argument is based on the Oklahoma Methamphetamine
    Registry Act, which establishes a registry for methamphetamine offenders and makes it
    unlawful for them to have Schedule V compounds or pseudoephedrine. See 
    Okla. Stat. Ann. tit. 63, § 2
    –701 (West 2011). We acknowledge that if there were a unique
    punishment under § 2–701 for methamphetamine offenders, then methamphetamine
    offenses would be divisible from the other offenses encompassed by the statute. But, as
    the government admits, the registry is not part of the formal punishment for the
    underlying offense. See Bivens v. State, 
    431 P.3d 985
    , 995 (Okla. Crim. App. 2018)
    (“The requirements of the Oklahoma Methamphetamine Registry Act were not part of the
    range of punishment for Appellant’s offense nor did any statutory provision permit a
    judge or a jury to impose, delay, alter, or suspend registration and no provision within the
    Oklahoma Methamphetamine Registry Act authorizes a sentencing judge or jury to
    17
    require or preclude compliance with the Act. . . . [T]he Oklahoma Methamphetamine
    Registry Act is a regulatory scheme that is entirely separate and distinct from the
    applicable punishment range.”). Accordingly, the registry act is irrelevant to our
    divisibility analysis.
    B.        Realistic-Probability Test
    Next, the government argues that even if § 2–401(A)(1) is not divisible by
    individual drug, the statute nevertheless satisfies the categorical approach because we can
    ignore the fact that Oklahoma characterizes three substances as controlled dangerous
    substances which are not federal controlled substances. It urges us to apply the realistic-
    probability test to reach that conclusion.
    The realistic-probability test has been applied by the Supreme Court to preclude
    defendants from arguing that a state statute does not satisfy the categorical approach
    because under certain imagined circumstances it would be possible to violate the state
    statute and not satisfy requirements under the ACCA for a violent felony or a serious
    drug offense. The test requires the defendant to show that there is “a realistic probability,
    not a theoretical possibility, that the State would apply its statute to conduct that falls
    outside the [definition in the federal statute].” Gonzales v. Duenas-Alvarez, 
    549 U.S. 183
    , 193 (2007). In Gonzales the Supreme Court rejected the defendant’s argument that
    his California vehicle-theft offense did not satisfy the federal statutory definition of theft
    because California courts could apply state accomplice-liability doctrine to non-theft
    conduct. See 
    id. at 190
    . The Court held that his “application of legal imagination to a
    state statute’s language” was insufficient. 
    Id. at 193
    . Instead, he was required to point to
    18
    cases in which the statute had been applied to such conduct. See 
    id.
     The government
    argues here that Defendant would fail the realistic-probability test because the parties
    have not identified any case prosecuting a defendant under § 2–401(A)(1) for conduct
    involving the three non-federally controlled substances.
    In this circuit, however, we have held that a defendant need not come forward with
    instances of actual prosecution when the “plain language” of the statute proscribes the
    conduct at issue. Titties, 852 F.3d at 1274. In Titties the government argued that the
    defendant was required to come forward with a “case in which Oklahoma has prosecuted
    someone under [the purported ACCA predicate statute] for pointing a firearm in obvious
    jest.” Id. We said that it was enough that the statute explicitly “reaches conduct
    undertaken for purposes of ‘whimsy, humor or prank.’” Id. So too here. The plain
    language of § 2–401(A)(1) expressly criminalized drugs that were not federally
    controlled and thus falls “outside the ACCA’s ambit.” Id.; see United States v. Abeyta,
    
    877 F.3d 935
    , 944 (10th Cir. 2017) (applying this aspect of Titties in the context of a
    sentencing-guidelines enhancement). It requires no “legal imagination,” Gonzales, 
    549 U.S. at 193
    , to see that Oklahoma law forbade distribution of three substances that are not
    federal controlled substances.
    In sum, we conclude that § 2–401(A)(1) is not divisible by individual drug.
    Because that statute prohibits the distribution of three drugs that were not federally
    controlled, Defendant’s conviction under that statute was not a “serious drug offense”
    19
    under the ACCA. The enhancement of Defendant’s sentence under the ACCA was
    therefore error. 5
    C.     Plain Error
    Because Defendant raised no objection to the ACCA enhancement during
    sentencing, the last obstacle he faces is plain-error review. “Under Federal Rule of
    Criminal Procedure 52(b), a plain error that affects substantial rights may be considered
    even though it was not brought to the court’s attention.” United States v. Faulkner, 
    950 F.3d 670
    , 672 (10th Cir. 2019) (brackets and internal quotation marks omitted). But to
    prevail, Defendant must show that “(1) an error occurred; (2) the error was plain; (3) the
    error affected his substantial rights; and (4) the error seriously affected the fairness,
    integrity, or public reputation of a judicial proceeding.” 
    Id.
     (brackets and internal
    quotation marks omitted).
    Our discussion above establishes error in Defendant’s sentencing. We further
    conclude that the error was plain. “An error is plain if it is clear or obvious under current,
    well-settled law” of this court or the Supreme Court. 
    Id. at 678
     (internal quotation marks
    omitted). That standard has been satisfied. Watkins is definitive and, in every material
    respect, is still good law in Oklahoma. See McKibbon, 878 F.3d at 976 (resolution of
    divisibility issue was plain, based in part on the “clear holding of the Colorado Supreme
    Court”). We reject the government’s contention that the absence of a previous case from
    this court specifically addressing § 2–401(A)(1) made the issue debatable. See Titties,
    5
    Having found error on this basis, we do not address Defendant’s alternative argument
    for reversal.
    20
    852 F.3d at 1272 n.19 (rejecting similar argument); Faulkner, 950 F.3d at 680 (“[T]here
    need not be an in-circuit case dealing with the precise state statute at issue if there is a
    case that sets forth a principle clearly generalizable to the subject statute.”). It is worth
    recalling that it falls on the government to establish divisibility with certainty, and we
    have suggested that this standard may benefit a defendant on plain-error review. See
    Titties, 852 F.3d at 1272 n.19. But see United States v. Bain, 
    874 F.3d 1
    , 31 (1st Cir.
    2017) (holding, based on the interplay between plain error and the divisibility question’s
    certainty requirement, that a defendant “can only succeed on the plain error standard if
    the . . . statute was clearly indivisible at the time of his conviction”). But Defendant
    needs no such benefit in this case, because Watkins clearly answers the divisibility
    question.
    Nor is the error in this case less plain because of prior precedential opinions of this
    court holding that a conviction under § 2–401 was a serious drug offense under the
    ACCA. See United States v. Villanueva, 
    821 F.3d 1226
    , 1239–40 (10th Cir. 2016);
    United States v. McMahon, 
    91 F.3d 1394
    , 1397–98 (10th Cir. 1996). In neither case, nor
    in any other published or unpublished decision of this court, did we address a claim that
    § 2–401 could not be a serious drug offense because some Oklahoma controlled
    dangerous substances are not controlled substances under federal law. Those opinions
    are therefore not in point. See Lowe v. Raemisch, 
    864 F.3d 1205
    , 1209 (10th Cir. 2017)
    (“If an issue is not argued, . . . the decision does not constitute a precedent to be
    followed.” (internal quotation marks omitted)).
    21
    The government also attacks plainness on a ground other than divisibility, arguing
    that § 2–401(A)(1) did not clearly fail under the categorical approach because the Fifth
    Circuit has held that the realistic-probability test would apply to that very statute. See
    Aplee. Br. at 32 (“Similarly, Mr. Cantu cannot establish plain error as to the issue of the
    application of the realistic probability test in determining whether a statute is
    categorically a serious drug offense. Neither this Court nor the Supreme Court has
    addressed this issue, and, as the Fifth Circuit noted in Vazquez [v. Sessions, 
    885 F.3d 862
    ,
    872–74 (5th Cir. 2018),] the law on this issue is not well-settled.”). But whatever another
    circuit has to say about the realistic-probability test does not make the law in this circuit
    any less clear. As discussed above, this court does not apply the realistic-probability test
    when the statute on its face clearly proscribes the relevant conduct.
    Thus, the error was plain. Because Defendant’s sentence exceeded the statutory
    maximum, he has presumptively satisfied the remaining elements of plain error. See
    Rosales-Mireles v. United States, 
    138 S. Ct. 1897
    , 1907–09 (2018) (sentencing-
    guidelines error that satisfies first three prongs of plain-error review will ordinarily
    satisfy fourth prong); Faulkner, 950 F.3d at 673 n.3 (noting “the now well-established
    principle that a plain error leading to the adoption of an incorrect, higher Guidelines
    range will ordinarily satisfy plain error review’s third and fourth prongs”). And the
    government has not suggested any reason why this case should not be encompassed by
    the general rule.
    22
    IV.       CONCLUSION
    We VACATE the sentence imposed by the district court and REMAND for
    resentencing.
    23
    19-6043, United States v. Cantu
    HARTZ, J., Circuit Judge, concurring
    I write separately to note two issues that this court may need to resolve in future
    cases that concern whether a prior conviction is a conviction for a violent felony or a
    serious drug offense under the ACCA.
    First, this court has been inconsistent about whether we apply the categorical
    approach based on the version of the state statutory offense in effect at the time of
    commission of the offense or at the time of conviction. Compare United States v. Titties,
    
    852 F.3d 1257
    , 1262 n.2 (10th Cir. 2017) (“[W]e focus on the [state] law as it applied to
    Mr. Tittle when he committed the offense.”), with United States v. Degeare, 
    884 F.3d 1241
    , 1255 n.7 (10th Cir. 2018) (recognizing the relevant state law as that existing at the
    time of the defendant’s state conviction). The timing issue can be subtle. As I
    understand the ACCA and Supreme Court authority, the comparison that must be made is
    between what the defendant could have been convicted of at the time of the commission
    of the predicate state offense and what constitutes a federal drug offense at the time of the
    federal offense. Two examples may clarify the matter. Say, at the time of the state
    conviction substance A was a state controlled substance but has never been a federal
    controlled substance. A quick look might lead to the conclusion that under the
    categorical approach the state conviction was not for a serious drug offense under the
    ACCA. But what if substance A had been added as a state controlled substance only a
    short time before the conviction and was not a state controlled substance when the
    defendant committed the state offense? In that circumstance, under ex post facto doctrine
    the defendant could not have been convicted of an offense involving substance A, so it
    would seem that the offense of which the defendant was convicted would have to have
    been a serious drug offense. Or, say that at the time of the state offense, substance A was
    a state controlled substance but not a federal controlled substance, yet substance A was a
    federal controlled substance by the time of the defendant’s federal offense. Then the
    defendant was on notice when he committed his federal crime that he had a serious drug
    offense on his record, and I would think that the state offense would be a proper predicate
    serious drug offense under the ACCA. The panel opinion does not address these
    possibilities because there is no dispute that at all relevant times Oklahoma law included
    three substances as controlled dangerous substances which were not controlled
    substances under federal law.
    The second issue is whether plain-error review is fully applicable when the alleged
    error would make the sentence illegal. This court has applied traditional plain-error
    analysis in that context. See United States v. Gonzales, 
    558 F.3d 1193
    , 1198–1200 (10th
    Cir. 2009) (error was not clear), abrogation on other grounds recognized by United
    States v. Snyder, 
    871 F.3d 1122
    , 1130 n.4 (10th Cir. 2017); United States v. Cernobyl,
    
    255 F.3d 1215
    , 1220 (10th Cir. 2001) (Apprendi error); United States v. Keeling, 
    235 F.3d 533
    , 539 (10th Cir. 2000) (Apprendi error but sentence affirmed because of failure
    to establish fourth prong).
    But some opinions by this court have suggested that we should always reverse
    when there has been an unpreserved error resulting in an illegal sentence, without the
    necessity of considering the second, third, or fourth prongs of plain-error review. See
    2
    Titties, 852 F.3d at 1275, following United States v. Gonzalez-Huerta, 
    403 F.3d 727
    , 739
    n.10 (10th Cir. 2005) (en banc), following United States v. Smith, 
    156 F.3d 1046
    , 1057
    (10th Cir. 1998), following United States v. Wainwright, 
    938 F.2d 1096
    , 1098 (10th Cir.
    1991), following United States v. Vance, 
    868 F.2d 1167
    , 1169 (10th Cir. 1989) (stating
    that “the imposition of an illegal sentence would constitute plain error”). (It should be
    pointed out, however, that in several opinions the court has conducted traditional plain-
    error analysis even while also invoking cases suggesting that we always reverse when
    there has been an illegal sentence. See, e.g., United States v. Mendenhall, 
    945 F.3d 1264
    ,
    1267–70 (10th Cir. 2019); Titties, 852 F.3d at 1272 n.19; United States v. Moyer, 
    282 F.3d 1311
    , 1317–20 (10th Cir. 2002).)
    This circuit’s special rule originated in our opinion in Vance, which predated the
    Supreme Court’s decision in United States v. Olano, 
    507 U.S. 725
    , 733–37 (1993), where
    the Supreme Court first set forth the four elements of plain-error review. Since Olano
    the Supreme Court has repeatedly insisted that unpreserved error can be grounds for
    reversal only if the four-prong test is satisfied, 1 unless the error was structural or

    date of statute); Puckett v. United States,

    Rule of Criminal Procedure 11); United States v. Cotton,

    , 629–31, 633
    (2002) (failure of indictment to allege element of the offense); United States v. Vonn, 
    535 U.S. 55
    , 60–74 (2002) (trial judge’s failure to advise represented defendant that he had
    right to counsel if he went to trial); Jones v. United States, 
    527 U.S. 373
    , 388–89 (1999)
    (rejecting argument that Federal Death Penalty Act created exception to requirement that
    defendant show that failure to give instruction was plain error); Johnson v. United States,
    
    520 U.S. 461
    , 465–67 (1997) (failure to instruct jury on element of offense).

    jurisdictional. 2 Perhaps all our decisions applying the circuit’s special rule would have
    reached the same result under traditional plain-error analysis. But maintaining a special
    rule for sentencing error may no longer be tenable. See United States v. Zangari, 
    677 F.3d 86
    , 95 (2d Cir. 2012) (criticizing this court’s failure to conduct four-prong plain-
    error analysis of sentencing error). If a case arises in which our special rule would make
    a difference, this court may wish to consider the matter en banc.
