    Commonwealth.
    LOWY, J.    A jury in the Superior Court convicted the
    defendant, Nicholas Desiderio, of one count of armed home
    invasion and three counts of armed robbery while masked.      The
    indictments were based on a theory of joint venture.      The jury,
    2
    however, were not instructed that, to convict the defendant of
    those charges on a joint venture theory, the Commonwealth was
    required to prove that the defendant knew that at least one
    coventurer was armed (for the count of armed home invasion), and
    that at least one coventurer was both armed and masked (for the
    counts of armed robbery while masked).   Those instructions were
    required.   See Commonwealth v. Bolling, 
    462 Mass. 440
    , 450
    (2012).
    The issue in this appeal is whether the failure to instruct
    the jury of these requirements created a substantial risk of a
    miscarriage of justice.   To decide whether an error creates a
    substantial risk of a miscarriage justice, we must determine "if
    we have a serious doubt whether the result of the trial might
    have been different had the error not been made."   Commonwealth
    v. Azar, 
    435 Mass. 675
    , 687 (2002), S.C., 
    444 Mass. 72
     (2005),
    quoting Commonwealth v. LeFave, 
    430 Mass. 169
    , 174 (1999).      In
    making this determination, we consider four factors, where
    applicable:   "[(1)] the strength of the Commonwealth's case,
    [(2)] the nature of the error, [(3)] the significance of the
    error in the context of the trial, and [(4)] the possibility
    that the absence of an objection was the result of a reasonable
    tactical decision."   Azar, supra.
    Although we recently have analyzed the question of
    substantial risk of a miscarriage of justice where an element of
    3
    a crime has been omitted from the jury instructions by
    determining whether "the evidence was 'so overwhelming' that
    'there is no likelihood that the omitted instruction materially
    influenced the jury's verdict[],'" Commonwealth v. Silvelo, 
    486 Mass. 13
    , 17-18 (2020), quoting Commonwealth v. Lutskov, 
    480 Mass. 575
    , 581 (2018), we now recognize that this formulation
    confuses rather than accurately reflects the necessary
    considerations of the substantial risk analysis in this context.
    As in all contexts, where an element of the crime charged
    has been omitted from the jury instructions, the factors for
    determining whether there was a substantial risk of a
    miscarriage of justice remain the focus of the analysis.     The
    factors applicable to circumstances where an element has been
    omitted in particular, however, and the manner in which they
    should be considered, are captured in the standard we
    articulated in Azar:   whether the presence of the omitted
    element was an ineluctable inference from the evidence at trial.
    See Azar, 
    435 Mass. at 687
    .   This standard, although undoubtedly
    high, is best understood as an explanation of the applicable
    substantial risk factors, and not a deviation from their
    application.   Where an element of a crime is omitted from the
    instructions, the jury are erroneously excused from applying the
    facts, as they find them, to that element.   This creates a risk
    of conviction in circumstances where the Commonwealth failed to
    4
    meet its burden of proof beyond a reasonable doubt as to the
    missing element.   Our substantial risk of a miscarriage of
    justice analysis in these circumstances thus must be
    correspondingly exacting.
    Because, in this case, the defendant's knowledge that the
    coventurers were armed or masked cannot be ineluctably inferred
    from the evidence at trial, the instructional error leaves us
    with a serious doubt whether the result of the trial might have
    been different had the jury been correctly instructed.     We
    therefore conclude that the error created a substantial risk of
    a miscarriage of justice.   As a result, we reduce the
    defendant's convictions of armed robbery while masked to unarmed
    robbery, and we vacate the judgment on the conviction of armed
    home invasion and set aside the verdict.
    Background.   We recite the relevant facts adduced at trial
    to establish the defendant's guilt as a coventurer.
    1.   The home invasion.   On the evening of January 5, 2014,
    the homeowner, his daughter, and her boyfriend, who was visiting
    for the evening, were all in the home.     The homeowner (victim)1
    went to bed at approximately 9 P.M., as he did most nights,
    after all the doors to his home were locked.     Not long after
    1 We recognize that the daughter and her boyfriend were also
    victims, but we refer to them by their relational titles to
    avoid confusion.
    5
    9 P.M., two masked men entered the home:   a shorter, heavy-set
    man with "Hispanic, African-American kind of complexion" and a
    tall, Caucasian man.2   The taller man carried a gun, and the
    shorter, heavier-set man carried a ten to twelve inch crowbar.
    It is undisputed that neither man was the defendant.
    The two men first entered the daughter's bedroom, where the
    daughter and her boyfriend were watching television.    The men
    carried two zip ties.   They tied the boyfriend's hands behind
    his back with one of the zip ties, and then whispered to each
    other.   The daughter heard one say, "Just go duct tape her," and
    the men proceeded to tie the daughter's hands behind her back
    with duct tape.   The men also placed duct tape over the mouths
    of the daughter and her boyfriend.   The men forced both to lie
    on the floor and placed a blanket over their heads.    They asked
    the daughter where her father was, but they did not ask about
    her mother, who was deceased.
    The men next went to the victim's bedroom.   The heavier-set
    man jostled the victim awake and flipped him over in bed.    He
    tied the victim's hands behind his back with the second zip tie.
    The men pulled the victim out of bed and pushed him down the
    hallway toward the living room where there was a stone chimney.
    2 The man with the darker complexion did not have his face
    fully covered by the mask, and while the lighter-complexioned
    man had a "full-fledged mask" on, the skin under his eyes was
    visible.
    6
    A picture that ordinarily hung on the chimney to hide a safe
    that was installed there had already been removed.    The safe was
    exposed.    At the taller gunman's insistence, the victim provided
    the men with the combination to unlock the safe.    Unable to open
    the safe, the men freed the victim's hands so that he could
    input the combination.    Once the safe was unlocked, the heavier-
    set man with the crowbar again bound the victim's hands, this
    time using duct tape.    Meanwhile, the taller man filled a
    pillowcase with the safe's contents, which included $50,000 in
    cash in one hundred dollar bills, and numerous pieces of jewelry
    belonging to the victim, his daughters, and his deceased wife.
    The men also took "a couple hundred" dollars from the victim's
    wallet, as well as the victim's father's Purple Heart and other
    military medals from a chest inside the victim's bedroom.
    After emptying the safe, the men led the victim to his
    daughter's bedroom, where the daughter and her boyfriend
    remained hand-bound on the floor.    The men forced the victim to
    get on the floor, and they put the blanket over his head as
    well.   The men asked if there was any more money or drugs in the
    house, and "ransack[ed]" the room, checking drawers and the
    mattress.    They then left with the cell phones of all three.
    After hearing the men leave, the boyfriend slipped his right
    hand loose from the zip tie and freed the victim.    The boyfriend
    next went to the window and saw the two men get into the front
    7
    and rear passenger seats of a waiting vehicle.     The vehicle was
    driven away, and the boyfriend found a telephone and dialed 911.
    Police were dispatched to the house at 9:52 P.M.     When police
    arrived, no signs of forced entry were detected.
    2.   Evidence connecting the defendant.     The defendant and
    the victim met around 2009, while the defendant was dating the
    daughter of the victim's cousin.    The defendant began to work
    for the victim's home construction business, and he did so for
    approximately three years until the victim scaled back his
    business in 2012 due to health issues.    During that time, the
    defendant was "like a family member" to the victim and often
    frequented the victim's home.    Indeed, the defendant became
    "very familiar" with the victim's home.    The defendant knew that
    the victim had a safe inside the stone chimney hidden behind a
    framed picture and that the victim kept large amounts of cash in
    this safe.   Further, the defendant knew that the victim's wife
    was deceased and that he lived with one of his daughters.
    After the defendant had left the victim's employ, the
    victim's health improved, and he purchased a two-family house to
    remodel and sell.   The victim learned that the defendant was
    displeased with his living situation, and he offered to allow
    the defendant to live in the second-story apartment of the two-
    family house in exchange for the defendant's assistance with
    remodeling and maintenance.     The defendant agreed.   The
    8
    relationship, however, broke down in the summer of 2013 when the
    victim sold the house and informed the defendant that he needed
    to find another place to live.   The defendant refused to leave
    and "threatened" the victim by stating, "If you weren't such an
    old, you know, SOB, I'd kick the shit out of you."   The victim
    retained counsel and paid the defendant a sum of money, after
    which the defendant agreed to vacate the premises.   The victim
    and the defendant had minimal contact following that dispute.
    Around the time of the home invasion on January 5, 2014,
    the defendant and Timothy Lavin shared three telephone calls and
    one text message.   At the time, the defendant and Lavin had
    known each other for twelve to thirteen years.   There was
    considerable testimony at trial that Lavin matched the
    description of the tall, Caucasian gunman involved in the
    invasion.   The first call was placed from Lavin's cell phone at
    9:08 P.M.   It connected to the defendant's cell phone at
    9:09 P.M., and it lasted fifteen seconds on the defendant's cell
    phone.3   The second call was placed at 9:15 P.M., and it lasted
    twenty-two seconds on the defendant's cell phone.    At 9:33 P.M.,
    Lavin sent a text message to the defendant that went unanswered.
    The third call was placed at 9:48 P.M., and it lasted seven
    3 There was some discrepancy between the length of the
    telephone calls registered to Lavin's and the defendant's cell
    phones due to the time it took to connect to the defendant's
    cell phone and for the defendant to answer.
    9
    seconds on the defendant's cell phone.   Each of the three calls
    connected to a cell tower that was less than one mile from the
    victim's home.
    On January 22, just over two weeks after the home invasion,
    Lavin, who had a suspended license, was observed by police
    driving a BMW motor vehicle.4   Lavin was known to have an
    inconsistent work history and money issues, and investigation by
    police revealed that he had purchased the BMW six days earlier,
    on January 16, for $3,700 in cash.   The BMW was registered to
    Lavin's longtime friend, Gerald Bates.   Lavin was arrested that
    day for operating a motor vehicle with a suspended license, and
    his bail was set for an amount between $1,500 and $2,000.    Lavin
    paid most of his bail with a "bundle of hundred dollar bills"
    that he had on his person.   The defendant and his girlfriend
    drove to the police station, and his girlfriend went inside and
    paid the remaining amount while the defendant waited in the car.
    Eight days later, police executed a search warrant at
    Lavin's residence.   Inside the residence, police discovered a
    mask, a firearm, and two locked safes.   One of the safes
    contained $2,700 in cash, and inside the other, multiple pieces
    of jewelry were found.   Among the jewelry recovered, the victim
    and his daughter identified the victim's high school class ring,
    4 Lavin stipulated at trial that his license was suspended
    on that date and that he had notice of the suspension.
    10
    the victim's wedding ring, the victim's deceased wife's watch
    and rings, and a necklace given to the daughter by her
    grandparents for graduating high school.
    3.     Procedural history.   A grand jury indicted the
    defendant on one count of armed home invasion and three counts
    of armed robbery while masked.5     The defendant's cases were
    joined with Lavin's for trial.6     At trial, the Commonwealth
    proceeded against the defendant under a theory of joint venture,
    contending that the defendant provided the coventurers with the
    necessary information to execute the home invasion and robbery
    and that he acted as the getaway driver.
    During the main jury charge, in accordance with
    Commonwealth v. Zanetti, 
    454 Mass. 449
    , 466 (2009), the judge
    instructed the jury that, to find the defendant guilty beyond a
    reasonable doubt of the crimes charged under a theory of joint
    venture, the Commonwealth was required to prove that the
    defendant knowingly participated in the commission of the
    offenses and shared or had the requisite intent for the
    offenses.    However, the judge did not instruct the jury that, to
    prove that the defendant shared the intent required for those

    conspiracy, which was dismissed at the Commonwealth's request.
    6 The shorter, heavy-set man involved in the home invasion
    was never identified or charged.
    11
    crimes, the Commonwealth needed to prove that the defendant knew
    that at least one coventurer was armed, for the charge of armed
    home invasion, and that at least one coventurer was armed and
    masked, for the charges of armed robbery while masked.   See
    Commonwealth v. Buth, 
    480 Mass. 113
    , 116, cert. denied, 
    139 S. Ct. 607 (2018)
     (under joint venture theory, "[w]here . . . an
    element of the offense is that the perpetrator is armed, the
    Commonwealth must prove that the defendant knew that at least
    one coventurer was armed"); Commonwealth v. Quinones, 
    78 Mass. App. Ct. 215
    , 219 (2010) ("To support a conviction on the charge
    of armed robbery while masked, the Commonwealth, proceeding on a
    joint venture theory of the defendant's guilt, had the burden of
    proving that the defendant knew that the principal perpetrators
    of the robbery . . . would be both armed and masked").   The
    defendant did not object to the jury instructions.   The jury
    convicted him of all four counts.
    The defendant appealed.   The Appeals Court, in a divided
    opinion, concluded that the failure to instruct the jury that
    the Commonwealth was required to prove that the defendant knew
    that his coventurers were armed and masked created a substantial
    risk of a miscarriage of justice because, pursuant to the
    standard we articulated in Silvelo, 486 Mass. at 18, "the
    evidence . . . was not 'so overwhelming' that 'there is no
    likelihood that the omitted instruction materially influenced
    12
    the jury's verdict[].'"7   Commonwealth v. Lavin, 
    101 Mass. App. Ct. 278
    , 279 (2022).    We allowed the Commonwealth's application
    for further appellate review, limited to the issue whether the
    failure to instruct the jury on the Commonwealth's burden to
    prove that the defendant knew that one of the coventurers was
    armed and masked created a substantial risk of a miscarriage of
    justice.
    Discussion.   1.   Standard of review.   Because the defendant
    did not object to the erroneous jury instructions, we review the
    case to determine whether the instructional error created a
    substantial risk of a miscarriage of justice.    See Bolling, 
    462 Mass. at 452
    .   "The substantial risk standard requires us to
    determine 'if we have a serious doubt whether the result of the
    trial might have been different had the error not been made.'"
    Azar, 
    435 Mass. at 687
    , quoting LeFave, 
    430 Mass. at 174
    .     In
    conducting this analysis, we are guided by four factors:     "[w]e
    consider [(1)] the strength of the Commonwealth's case, [(2)]
    the nature of the error, [(3)] the significance of the error in
    the context of the trial, and [(4)] the possibility that the
    7 The Appeals Court, at the Commonwealth's request, reduced
    the defendant's convictions of armed robbery while masked to
    unarmed robbery and remanded for resentencing of those charges,
    but vacated the defendant's conviction of armed home invasion,
    leaving to the Commonwealth the decision whether to retry the
    defendant on that charge. See Commonwealth v. Lavin, 
    101 Mass. App. Ct. 278
    , 301 (2022).
    13
    absence of an objection was the result of a reasonable tactical
    decision."   Azar, supra.   See Commonwealth v. Alphas, 
    430 Mass. 8
    , 13 (1999) (setting forth factors applicable to standard of
    review for unpreserved errors in noncapital cases).    See also
    Commonwealth v. Randolph, 
    438 Mass. 290
    , 298 (2002)
    (articulating formulation as series of questions).
    We previously have addressed the particular suitability of
    the substantial risk of a miscarriage of justice standard to
    situations where the elements of a crime are stated erroneously
    or are omitted from the jury instructions.    See Silvelo, 486
    Mass. at 17 n.7, quoting Azar, 
    435 Mass. at 687
    .    In Azar, where
    the judge provided an erroneous definition of the "so-called
    third prong of malice" in a murder trial, which lowered the
    Commonwealth's burden of proof, we surveyed cases where the same
    error had or had not required reversal.    See Azar, supra at 682,
    687-688, and cases cited.   We deduced from those cases that a
    new trial is not required where the evidence at trial did not
    permit a finding of lesser proof than what is required under the
    third prong of malice -- the erroneously stated element.    Id. at
    687-688.   We therefore stated that the proper question in such
    circumstances is "whether the evidence required the jurors to
    find [the omitted or erroneously stated element, had it been
    correctly stated]."   Id. at 688.   In other words, where the
    presence of the omitted or erroneously stated element, "as it is
    14
    correctly understood, can be 'ineluctably inferred' from the
    evidence," a new trial is not necessary.   Id., quoting
    Commonwealth v. Vizcarrondo, 
    427 Mass. 392
    , 397 (1998), S.C.,
    
    431 Mass. 360
     (2000).
    More recently, in Silvelo, 486 Mass. at 17, where the judge
    omitted from the jury instructions an essential element of the
    crime of possession of a loaded firearm, and the defendant
    failed to object, we similarly applied the substantial risk of a
    miscarriage of justice standard.   There, we stated that our
    consideration in this context was "to determine whether the
    evidence was 'so overwhelming' that 'there is no likelihood that
    the omitted instruction materially influenced the jury's
    verdict[].'"   Id. at 17-18, quoting Lutskov, 
    480 Mass. at 581
    .
    In so stating, we specifically acknowledged that "this
    formulation diverge[d] from Azar, 
    435 Mass. at 688
    , under which
    we analyzed whether the 'evidence required the jury to [have
    found]' or to have 'ineluctably inferred' that the Commonwealth
    carried its burden of proving the omitted element beyond a
    reasonable doubt."   Silvelo, supra at 18 n.9.   We nevertheless
    emphasized that, in using this particular formulation, we did
    not "intend this semantic difference in language to change the
    stringency of the standard announced in Azar."   Id.   We meant
    it.
    15
    The reason the substantial risk of a miscarriage of justice
    standard is stringent in this context is not because we apply a
    different test to this type of error from the one we apply to
    others.    In all noncapital cases,8 where a defendant has waived a
    claim of error, our review is limited to the substantial risk of
    a miscarriage of justice standard, which "calls for us to decide
    if we have a serious doubt whether the result of the trial might
    have been different had the error not been made."9    LeFave, 430
    Mass. at 174-175 & n.6.    However, in making this determination,
    we must consider the relevant factors applicable to the
    substantial risk analysis, including the nature of the error and
    its significance in the context of the evidence presented at
    trial.    See Alphas, 
    430 Mass. at 13
    .   Omitting an element from
    the jury instructions is an error of constitutional dimension,
    see Neder v. United States, 
    527 U.S. 1
    , 12-14 (1999), that poses
    a significant risk that the jury will convict the defendant on
    8 In capital cases, we review claims of unpreserved error
    for a substantial likelihood of a miscarriage of justice.
    Commonwealth v. Duke, 
    489 Mass. 649
    , 659 (2022).
    9 We also have said that "[a]n error creates a substantial
    risk of a miscarriage of justice unless we are persuaded that it
    did not 'materially influence[]' the guilty verdict." Alphas,
    
    430 Mass. at 13
    , quoting Commonwealth v. Freeman, 
    352 Mass. 556
    ,
    564 (1967). The two explanations produce the same result: "An
    error may be said to have materially influenced the verdict only
    if we are left with 'a serious doubt [as to] whether the result
    of the trial might have been different had the error not been
    made'" (citation omitted). Commonwealth v. Horne, 
    476 Mass. 222
    , 228 (2017).
    16
    proof less than what is required for the crime charged.     See
    Azar, 
    435 Mass. at 688-689
    .    And on appeal, "our role is not to
    sit as a second jury."    
    Id. at 689
    .   Thus, in order for us not
    to have serious doubt that the defendant's guilt has been fairly
    adjudicated, such that the error did not create a substantial
    risk of miscarriage of justice, we must analyze the evidence
    pertaining to that element with an exacting lens.     See 
    id. at 687-688
    .
    This substantial risk analysis contemplates whether the
    evidence addressing the omitted or erroneously stated element
    was overwhelming or uncontested at trial.     Compare Lutskov, 
    480 Mass. at 581
     (omitted instruction on Commonwealth's burden to
    prove defendant's age created no substantial risk of miscarriage
    of justice where evidence of age was "so overwhelming that [it]
    was not a contested issue at trial"), with Bolling, 
    462 Mass. at 450-452
     (omitted instruction on Commonwealth's burden to prove
    defendant knew coventurer was armed created substantial risk of
    miscarriage of justice where evidence of defendant's knowledge
    that one coventurer was armed "was not overwhelming" and was
    contested at trial).     Cf. Johnson v. United States, 
    520 U.S. 461
    , 470 (1997) (unpreserved error of omitted instruction on
    materiality in perjury prosecution created no "miscarriage of
    justice" where "evidence supporting materiality was
    17
    'overwhelming,'" and "[m]ateriality was essentially
    uncontroverted at trial" [citation omitted]).
    Thus, in providing another articulation of how we analyze
    substantial risk of a miscarriage of justice in the omitted
    element context in Silvelo, 486 Mass. at 17-18, we asked
    "whether the evidence was 'so overwhelming' that 'there is no
    likelihood that the omitted instruction materially influenced
    the jury's verdict[]'" (citation omitted).   We now acknowledge
    that this articulation of the standard is flawed.     It is so, in
    part, because it mirrors our prior explanation of the standard
    for analyzing harmless error -- the standard applicable to
    preserved constitutional error.   See Commonwealth v. Castano,
    
    478 Mass. 75
    , 82 (2017), quoting Commonwealth v. Dagraca, 
    447 Mass. 546
    , 555 (2006) ("an error may be harmless beyond a
    reasonable doubt where the Commonwealth's evidence is so
    'overwhelming' that it 'nullif[ies] any effect the erroneously
    admitted [evidence] might have had on the jury or the
    verdict'").   But more so, this formulation poses a question
    that, in most cases, is extremely difficult to answer:     whether,
    because the evidence was "so overwhelming," there is no
    likelihood, theoretical or otherwise, that the error materially
    influenced the verdict.   Silvelo, supra.
    Our review of unpreserved errors is not whether there is
    any risk of a miscarriage of justice, but rather, it is whether
    18
    that risk is a substantial one.   See Azar, 
    435 Mass. at 676
    ,
    quoting LeFave, 
    430 Mass. at 175
     ("society's justified interest
    in finality . . . has long been implicit, and sometimes
    explicit, in our announcements that any late-arriving issue will
    prevail only if the issue presents a substantial risk of a
    miscarriage of justice").   See also Commonwealth v. Russell, 
    439 Mass. 340
    , 351 (2003) ("As the terminology implies, a
    'substantial risk of a miscarriage of justice' refers to a risk
    that has some genuine substance to it.   That standard does not
    encompass an abstract, theoretical possibility of a miscarriage
    of justice, utterly divorced from the case as it was
    tried. . . .   [If] the only risk identified is one that is
    totally removed from or at odds with that 'context,' we may rest
    assured that the error did not give rise to a substantial risk
    of a miscarriage of justice").
    To be sure, whether the Commonwealth's evidence is
    "overwhelming," let alone "so overwhelming," is certainly a
    consideration in the substantial risk calculus as a general
    matter.   It is, however, one part of that analysis.   See Alphas,
    
    430 Mass. at 13
    .   The analysis of substantial risk of a
    miscarriage of justice must consider the four factors as they
    apply to the individual circumstances of each case.     But not all
    of the factors will be applicable in every case, and the way
    that they apply may vary depending on the particular
    19
    circumstances.   Where the nature of the error is omitting an
    element from the jury instructions, specifically, our assessment
    of the strength of the Commonwealth's evidence must focus on the
    evidence addressing the element that was stated erroneously or
    omitted from the jury instructions.
    In this case, notably, the Commonwealth does not argue that
    the fourth factor -- whether it can be inferred that the
    defendant's failure to object to the erroneous jury instructions
    was a reasonable tactical decision -- is applicable.   See
    Alphas, 
    430 Mass. at 13
    .   Nor can we now contemplate a case
    where the failure to object to jury instructions relieving the
    Commonwealth of its burden to prove a necessary element beyond a
    reasonable doubt would be the result of a reasonable tactical
    decision.10   See Bolling, 
    462 Mass. at 452
     ("it seems unlikely
    that the failure to request the instruction was a reasonable
    10We note that the circumstances here are distinguishable
    from those where a defendant strategically declines to request
    an instruction on the elements of a lesser included offense.
    See, e.g., Commonwealth v. Glover, 
    459 Mass. 836
    , 844 (2011)
    (reasonable strategic decision not to request instruction on
    voluntary manslaughter so as to proceed solely on theory of
    self-defense). But see 
    id.
     at 843 n.8 ("However, where defense
    counsel's strategic decision not to request an instruction on a
    lesser included offense . . . is manifestly unreasonable, a
    judge may need to exercise the inherent authority to give the
    instruction sua sponte to protect the case from the risk of
    reversal on appeal"). We also note that a judge may always
    provide an instruction on a lesser included offense that is
    warranted from the evidence, regardless of whether the defendant
    or the Commonwealth objects. See Commonwealth v. Russell, 
    470 Mass. 464
    , 480 (2015).
    20
    tactical decision because requiring the jury to make an
    additional finding about the defendant's state of mind before
    convicting him could not have prejudiced his case"); Azar, 
    435 Mass. at 689
     ("there is no reasonable tactical basis for a
    failure to object to a mistaken and unfavorable [to the
    defendant] definition of an element of the crime").
    Accordingly, where an element that the Commonwealth is
    required to prove beyond a reasonable doubt is omitted from the
    jury instructions, our analysis of substantial risk of a
    miscarriage of justice is limited to considering the three
    remaining factors, which focus on the strength of the
    Commonwealth's evidence in light of the nature of the error and
    its significance in the context of the trial.     These factors are
    all captured by the standard articulated in Azar, 
    435 Mass. at 688
    .    We therefore clarify today that, to determine whether a
    substantial risk of a miscarriage of justice is created by the
    omission of a required element from the jury instructions, the
    question is, as we said in Azar, supra, whether the presence of
    the omitted element was an ineluctable, or inescapable,
    inference from the evidence presented at trial.    In light of the
    nature and significance of this type of error, only when the
    answer to that question is "yes," in this context, will the
    error not create a substantial risk of a miscarriage of justice.
    In other contexts, of course, the substantial risk determination
    21
    will depend on the circumstances of each case, considering the
    applicable factors.   See Alphas, 
    430 Mass. at 13
    .
    2.   Application.   To prove beyond a reasonable doubt that
    the defendant was guilty of armed home invasion and armed
    robbery while masked under a theory of joint venture, the
    Commonwealth was respectively required to prove that the
    defendant knew that one coventurer was armed, and that one
    coventurer was both armed and masked.   We therefore must
    determine whether the presence of these elements was an
    ineluctable inference from the evidence at trial.11    Because, as
    to either element, we conclude it was not, we are left with a
    serious doubt whether the result of the trial might have been
    different had the instructional error not been made.
    There was no direct evidence that the defendant knew that
    the coventurers were armed or masked.   This is "not
    determinative," however, because a defendant's knowledge that a
    coventurer is armed or masked may be proved by circumstantial
    11The Commonwealth's argument that this standard should not
    apply in this case because the requirements of joint venture are
    not elements of the underlying crimes is unavailing. While
    "joint venture is neither a crime nor an element of a crime,"
    Commonwealth v. Fluellen, 
    456 Mass. 517
    , 522 (2010), the
    perpetrator being armed is an element of both underlying crimes
    in this case. See G. L. c. 265, §§ 17, 18C. Thus, to convict
    the defendant of those crimes under a joint venture theory, the
    Commonwealth needed to prove that the defendant knew that one
    coventurer was armed. See Buth, 
    480 Mass. at 116
    . The same is
    true of the preparator being masked for the charge of armed
    robbery while masked. See Quinones, 78 Mass. App. Ct. at 219.
    22
    evidence.   See Commonwealth v. Ellis, 
    432 Mass. 746
    , 762 (2000).
    The Commonwealth directs our attention to nine pieces of
    circumstantial evidence that it asserts should leave us with no
    serious doubt that the defendant's guilt as a coventurer was
    fairly adjudicated.
    This circumstantial evidence includes (1) evidence
    suggesting that the defendant told the coventurers intimate
    details about the victim's home, such as the location of the
    safe, indicated by the removal of the picture from the chimney;
    (2) evidence suggesting that the defendant knew and told the
    coventurers that the victim kept large amounts of cash in the
    safe; (3) evidence suggesting that the defendant told the
    coventurers that only two people would be in the home, such as
    them having brought only two zip ties; (4) evidence suggesting
    that the defendant told the coventurers that the victim's wife
    was deceased, such as the coventurers not asking the daughter
    where her mother was; (5) evidence that the defendant had a
    motive to seek revenge and steal money from the victim due to
    their animosity arising out of the defendant's living
    arrangement in the summer of 2013; (6) evidence that the
    defendant and Lavin communicated via cell phone on the night of
    the home invasion; (7) historical cell site location information
    (CSLI) evidence placing the defendant in the vicinity of the
    home invasion at the time it occurred; (8) evidence that the
    23
    defendant and his girlfriend drove to the police station to pay
    Lavin's bail, but the defendant stayed in the car, inferably to
    avoid police connecting him with Lavin; and (9) evidence that
    the defendant and Lavin had a close relationship.
    There is no question that the coalescence of this
    circumstantial evidence told a powerful and persuasive story
    that the defendant was substantially involved in the home
    invasion and subsequent robbery.    It did not, however, require
    the jury to find that the defendant knew that his coventurers
    were armed and masked during the commission of those crimes.
    See Azar, 
    435 Mass. at 688
    .   While the evidence suggesting that
    the defendant assisted with orchestrating the crimes and acted
    as the getaway driver may have been sufficient for the jury to
    infer that the defendant possessed the requisite knowledge, see
    Commonwealth v. Netto, 
    438 Mass. 686
    , 703 (2003), such
    inferences were hardly ineluctable.12
    At trial, there was no evidence -- direct or circumstantial
    -- that one of the coventurers conspicuously possessed a weapon
    or a mask around the defendant.    The most forceful evidence that
    the defendant knew that the coventurers were armed and masked
    was the evidence that placed him in the vicinity of the home on
    12For sufficiency purposes, "[i]nferences must be
    reasonable, but they do not have to be inescapable." Netto, 
    438 Mass. at 703
    . The same is not true of our calculus here.
    24
    the night in question and suggested that he drove the getaway
    vehicle.   However, as the Commonwealth has acknowledged, to
    adjudicate the defendant guilty as a coventurer, the jury were
    not required to find that the defendant participated in the
    crimes by driving the getaway vehicle.   Given the other evidence
    of his participation, and the defendant's vehement challenges to
    the accuracy of the CSLI evidence placing him near the victim's
    home that night,13 it is not readily apparent that the jury did
    so find.   Even if the jury did find that the defendant was the
    getaway driver, although it would have been permissible for them
    to infer the defendant's knowledge from this fact, see
    Commonwealth v. Cannon, 
    449 Mass. 462
    , 470-471 (2007), the
    absence of evidence that the coventurers exhibited weapons or
    masks when leaving or entering the vehicle could also have led
    the jury to reach the opposite inference.
    In short, while the evidence that the defendant knew that
    the coventurers were armed and masked during the home invasion
    13Specifically, on cross-examination of the State police
    trooper who testified for the Commonwealth about the defendant's
    CSLI, the defendant elicited testimony that historical CSLI such
    as that used in this case is the least accurate method to
    identify the location of a cell phone. The trooper further
    testified on cross-examination that a cell site tower may have a
    range of five or more miles, and that cell phones do not always
    connect to the cell tower to which they are physically closest.
    In closing, the defendant relied heavily on this testimony to
    undermine the Commonwealth's position that the defendant's CSLI
    placed him in the vicinity of the victim's home at the time of
    the crimes.
    25
    and robbery was certainly sufficient, and from that evidence the
    jury were more than entitled to draw those inferences, we cannot
    say that the inferences were ineluctable.   Without proper
    instruction informing the jury that the Commonwealth was
    required to prove the defendant's knowledge of those two
    particulars beyond a reasonable doubt, we are left with a
    serious doubt whether the outcome of the trial would have been
    different had the instructional error not been made.     The error
    therefore created a substantial risk of a miscarriage of
    justice.
    Conclusion.   Consistent with the Commonwealth's request in
    the Appeals Court, the defendant's convictions of armed robbery
    while masked are reduced to unarmed robbery, and the matter is
    remanded to the Superior Court for resentencing of those
    offenses.   The judgment on the defendant's conviction of armed
    home invasion is vacated and the verdict is set aside.
    So ordered.
