    SELYA, Circuit Judge.   A voicemail message, containing
    a crude and highly charged racial slur, sparked a controversy that
    rocked the tony town of Brookline, Massachusetts (the Town).    On
    December 1, 2015, the controversy spilled over into the federal
    district court:   plaintiff-appellant Gerald Alston, the recipient
    of the voicemail message, filed this civil rights action alleging
    violations of 
    42 U.S.C. §§ 1981
    , 1983, and 1985.     The operative
    complaint named a long list of defendants, including (as relevant
    here) the Town, the Brookline Board of Selectmen (the Board), the
    Town's counsel and human resources director, and select members of
    the Board (Nancy Daly, Betsy DeWitt, Ben Franco, Kenneth Goldstein,
    Bernard Greene, Nancy Heller, Jesse Mermell, and Neil Wishinsky).1
    All of the individual defendants were sued in both their personal
    and official capacities.
    1 Alston also named Stanley Spiegel, a Town Meeting member,
    and Local 950, International Association of Firefighters (the
    Union) as defendants.    The district court dismissed the claims
    against Spiegel with prejudice. See Alston v. Town of Brookline,
    No. 15-13987, 
    2017 WL 1536213
    , at *1 (D. Mass. Apr. 26, 2017).
    The court later entered summary judgment in favor of the Union.
    Alston v. Town of Brookline, No. 15-13987, 
    2020 WL 1615408
    , at *5
    (D. Mass. Apr. 2, 2020).
    Alston appealed both of these orders. We recently affirmed
    the order of dismissal as to Spiegel. See Alston v. Spiegel, 
    988 F.3d 564
    , 569 (1st Cir. 2021) [No. 20-1434, slip op. at 3].
    Alston's claims against the Union, which raise a distinct set of
    issues, will be resolved in a separate and subsequent opinion.
    See, e.g., United States v. Santiago-Rivera, 
    744 F.3d 229
    , 231 n.1
    (1st Cir. 2014).
    - 3 -
    The    defendants   denied    liability   and   —    following
    discovery, the dismissal of the claims against Mermell, and other
    pretrial skirmishing — moved for summary judgment.          The district
    court granted their motions.     See Alston v. Town of Brookline, No.
    15-13987, 
    2020 WL 1649915
    , at *5 (D. Mass. Apr. 2, 2020).             This
    timely appeal ensued.
    We previously noted that, due to the complexity of
    Alston's appeal, we would resolve it in a series of separate
    opinions.   See Alston v. Spiegel, 
    988 F.3d 566
    , 569 n.1 (1st Cir.
    2021).   In this opinion, we address the appeal only insofar as it
    relates to the district court's grant of summary judgment in favor
    of the above-enumerated defendants.         For the reasons discussed
    below, we affirm in part, vacate in part, and remand for further
    proceedings.      Withal, we retain appellate jurisdiction over those
    aspects of the appeal not yet adjudicated.
    I. BACKGROUND
    We draw a representative sampling of the facts from the
    amplitudinous summary judgment record.       Alston, a black man, began
    working for the Brookline Fire Department (the Department) in 2002
    as a firefighter.     During the spring of 2010, he sustained a work-
    related injury that temporarily put him out of work.            On May 30,
    2010, Paul Pender, then a lieutenant in the Department and Alston's
    supervisor, called Alston to check on his well-being.           When Alston
    did not pick up the telephone, Pender left a voicemail, which
    - 4 -
    concluded with Pender using a racial slur ("f.....g n....r"),
    apparently in reference to Alston.
    Unsure about how to proceed, Alston sought the advice of
    senior   firefighters.    He   also   played   the   voicemail   for   the
    Department's chief of operations, Michael O'Reilly.        O'Reilly did
    not report the incident to the then-Chief of the Department (Peter
    Skerry) but instead agreed with Alston that Alston would speak
    with Pender directly.
    Before Alston could reach out to Pender, Pender learned
    through another firefighter that Alston had told O'Reilly about
    the voicemail.    On July 8, 2010, Pender called Alston and assured
    him that the racial slur was not intended for Alston.        Rather, it
    was intended for "a young black gang-banger" who had cut off Pender
    in traffic.      Offended by Pender's explanation, Alston abruptly
    ended the call.
    The next time Alston spoke to Pender was on July 10,
    2010.    Pender again tried to explain the context in which he had
    uttered the racist comment.    He added that reporting the voicemail
    to O'Reilly "was the stupidest thing [Alston] could have ever
    done."   He then asked Alston, "Are you after my job or something?"
    Alston filed a written complaint with Chief Skerry on
    July 28, 2010.     At a meeting two days later attended by Alston,
    his wife, Skerry, O'Reilly, and then-Town counsel Jennifer Depazo,
    Alston played the voicemail.    In response, Skerry determined that
    - 5 -
    Pender's language constituted a fireable offense and informed
    Alston that he would advocate for Pender's termination.      Alston
    replied that he did not want Pender to lose his job.     Later that
    day, Skerry transferred Pender to another station.
    In August of 2010, the Board met to discuss possible
    disciplinary action vis-à-vis Pender.       Chief Skerry initially
    recommended a suspension of four tours of duty for Pender, but the
    Board rejected that recommendation and imposed a negotiated two-
    tour suspension.    This decision took into account Pender's prior
    record at the Department and his expression of remorse.       Along
    with the suspension, Pender made certain other concessions:      he
    waived his right of appeal, committed to undergo anger management
    and diversity training and mediation with Alston, and consented to
    permanently transfer out of the station where Alston worked.
    Alston was not called as a witness before the Board.
    Roughly two weeks after the effective date of Pender's
    suspension, the Town promoted Pender to temporary fire captain.
    In doing so, the Town used Pender's greater seniority to break a
    tie with another firefighter, citing past practice.
    On September 17, 2010 (in anticipation of Alston's post-
    injury return to work), Chief Skerry met with the Department's
    officers.    He reminded them that the Town has zero tolerance for
    either discrimination or retaliation.
    - 6 -
    A week after that meeting, Pender was given a medal at
    the White House for his heroism in connection with a 2008 fire.
    Two days after Alston's return to work, Joe Canney, a fellow
    firefighter, wrote (on a password-protected union blog to which
    only union members had access) about a "faceless coward" who was
    marring Pender's receipt of the award.   Inferring that Canney was
    speaking about him, Alston complained to Skerry, who said that he
    would request deletion of the post.      The post was subsequently
    deleted.
    In October of 2010, Alston told Skerry that he was
    disappointed with the Town's coddling of Pender.      In response,
    Skerry wrote to Alston, suggesting that he seek mental health
    counseling.   On October 14, Alston began seeing a counselor, and
    he was subsequently excused from work for days at a time for
    evaluation and treatment of workplace stress.     On November 24,
    Alston became agitated at work as a result of a "routine scheduling
    decision."    Taken to a local hospital, he tested positive for
    cocaine.
    Alston has presented evidence showing that, in February
    of 2011, Pender again berated him for reporting the voicemail.
    Pender allegedly told Alston that he had "destroyed [Pender's]
    life and ruined [Pender's] career."
    Chief Skerry retired later that year, and the Board
    appointed Paul Ford as the new Chief.     In early 2012, Ford met
    - 7 -
    with Alston to talk about how things were between Alston and
    Pender.     Alston told Ford that he wanted to move on from the
    voicemail incident but that Pender refused even to shake his hand.
    Alston was injured in a motor vehicle accident in May of
    2012.     That month, Alston filed a discrimination charge with the
    Massachusetts      Commission     Against       Discrimination    (MCAD).      In
    November of 2012, he amended the charge to incorporate a claim for
    retaliation.      Specifically, he alleged that he had been "shunned,
    isolated, and mocked by his fellow firefighters at the direction
    and instruction of his superiors," that these conditions had been
    worsening over the past three years, and that he had repeatedly
    complained       about   his    plight     without       any   intervention   by
    management.      Spurred by Alston's charge, the Town human resources
    director, Sandra DeBow, launched an investigation and concluded
    that Alston's allegations were without merit.
    On    May    1,    2013,    Chief     Ford   recommended    Pender's
    permanent    promotion.        The     Board    acquiesced,    making   permanent
    Pender's promotion to captain.             By the time of this promotion,
    Alston had noticed that firefighters were shunning him, ignoring
    him, leaving the common areas as soon as he entered, and leaving
    him out of family social events (to which he previously had been
    invited).     Alston has also presented evidence showing that Pender
    used his new position to tell recruits that Alston's lawsuit was
    "a bunch of lies."        Pender's account is different:           he testified
    - 8 -
    that he talked with five recruits "who were all minorities" and
    that all of them were "shocked . . . that something so benign is
    going on seven and a half years later."
    On June 17, 2013, Alston filed suit on his MCAD charge
    in the state superior court.         Two days later, a Town human
    resources official, Leslea Noble, notified Alston that she wished
    to interview him about complaints that he had voiced to coworkers.
    Alston did not respond.       When Alston's state-court suit became
    public, the Town's counsel, Joslin Murphy, reminded Pender of his
    non-retaliation obligations.
    In September of 2013, one of the selectwomen, Nancy Daly,
    circulated a letter from a retired black firefighter.        The letter
    criticized Alston and asserted that it was insulting to all
    firefighters for Alston to claim that he could not count on fellow
    firefighters to save him in a life-threatening situation.
    It   is    undisputed   that    Alston   and   Pender   had   a
    conversation on October 31, 2013.         Viewing that incident in the
    light most favorable to Alston, see Houlton Citizens' Coal. v.
    Town of Houlton, 
    175 F.3d 178
    , 184 (1st Cir. 1999), he approached
    Pender, saying that his lawsuit was not personal and had nothing
    to do with Pender.       The lawsuit, he said, was about the Town
    respecting him.     Pender again apologized for the voicemail message
    but then admonished Alston, stating that the lawsuit was dragging
    his name through the mud and causing pain to his family.          Pender
    - 9 -
    also repeatedly declared that the allegations in the complaint
    were lies.
    At the end of his shift on December 19, 2013, Alston
    found the word "Leave" written in the dust on the door next to the
    seat on the firetruck to which he had been assigned.                He called
    this display to the attention of two coworkers, Ryan Monahan and
    Cormac Dowling.      Chief Ford was informed of the incident, and he
    reported it to both DeBow and Murphy.            Three days later, Alston
    referred to the incident in front of coworkers and stated that,
    "people go postal over matters like this."                  That night, Ford
    interviewed Alston about his statement and — concerned about
    Alston's    mental   state   —   placed   him   on   paid   leave   pending   a
    psychiatric evaluation.          From that point forward, Alston never
    resumed work as a firefighter.
    Ford immediately arranged to meet with DeBow and Murphy,
    relating that Alston had spoken to him about the incident in a
    "cordial and calm manner."         In his view, Alston was not a threat
    to his coworkers.      He therefore opposed the issuance of a "stay-
    away order" against Alston.        Consistent with Ford's position, both
    Monahan and Dowling said that they did not feel threatened by
    Alston's comment.     Another firefighter recalled Alston saying that
    he was not the type of person who would carry out a workplace
    shooting.
    - 10 -
    Yet, Chief Ford did not have the last word:            on December
    27, acting at the direction of the Town's hierarchs, he ordered
    Alston to stay off the Town's property due to the "going postal"
    comment.    Alston's later attempt to make clear that he had never
    made a comment about shooting the men in the station fell on deaf
    ears.
    The Town soon circulated a flyer to its police officers.
    The flyer included a color photograph of Alston and the type of
    car he drove, listing his name, address, date of birth, and height.
    It claimed that Alston had "made statements referring to 'going
    postal,' obtaining a firearm and returning to a firehouse to cause
    harm."     There is no evidence in the record to substantiate the
    allegations in the flyer beyond the "going postal" comment.
    On January 6, 2014, Alston was examined by a psychiatrist
    chosen by the Town (Dr. Andrew Brown).           Dr. Brown lost little time
    in communicating to Chief Ford and DeBow that Alston did not pose
    a threat to himself or others.
    On    January   13,    DeBow   notified    Alston   that    she   was
    investigating both the "Leave" incident and the "going postal"
    comment    as    possible   violations     of   Town   policies.       She    also
    confirmed that he had been placed on paid leave pending completion
    of those investigations.          She requested that Alston contact her to
    arrange an interview, but Alston did not respond.                  At the same
    time, DeBow requested additional pictures of the "Leave" message
    - 11 -
    because the picture Alston had submitted reflected glare that
    "obscured       some    of    the   letters"    and,    thus,    complicated      any
    handwriting analysis.            Alston did not comply and — on May 14 —
    DeBow reported that she could not conclude that the "Leave" message
    was discriminatory or retaliatory because the Town's handwriting
    expert could not identify the author.                 DeBow also speculated that
    a nearby fraternity might have written the message; although "there
    [was] no evidence to establish that this [fraternity] scenario"
    occurred, the "possibility [could not] be discounted."
    That same day, the Town nonetheless suspended Alston for
    two tours for violating its workplace safety policy.                          It also
    removed him from paid administrative leave and placed him on paid
    sick leave. Alston's placement on sick leave stemmed from concerns
    about    his    mental       health.    Both    Dr.    Brown    and   Alston's    own
    psychiatrist (Dr. Michael Kahn) worried that Alston might not be
    mentally fit to perform his firefighter duties.                       In the end,
    Alston's eventual return to work was conditioned on receipt of
    appropriate mental health treatment, reevaluation by the Town's
    psychiatrist, and random drug testing.
    On October 23, the Town notified Alston that he had
    exhausted      his     available    leave.2     Alston    was    asked   to    resume
    2 Meanwhile, on July 8, the state superior court entered
    judgment for the Town on Alston's discrimination and retaliation
    claims, resting its decision on procedural grounds.
    - 12 -
    contributing his share of his municipal health insurance premiums.
    Although Alston did not respond to this request, the Town continued
    to cover Alston's share and his health insurance remained in force.
    The   Town   and   the   Department   attempted   to   schedule
    meetings with Alston to explore whether he could return to work
    with reasonable accommodations.        Alston failed to appear for a
    planned November 10 meeting.       When he insisted on bringing members
    of the public to a November 24 meeting, Ford and DeBow refused to
    hold the meeting with Alston's guests present.        DeBow then wrote
    to Alston, notifying him of a scheduled reevaluation appointment
    with Dr. Brown.   Alston's counsel replied that Alston would not
    attend.
    Alston then formally asked the Board to review his claims
    of discrimination and retaliation.          The Board's chair (Kenneth
    Goldstein) replied in December that "[w]e are . . . informed that
    the supervisor who uttered those words to you and was formally
    disciplined for the incident offered his apology to you, and has
    since repeatedly expressed remorse and regret for his conduct."
    The following month, Alston contacted Goldstein, complaining about
    an incident involving Stanley Spiegel, a Town Meeting member.         See
    supra note 1.   An investigation commissioned by the Town revealed
    that Spiegel had told an Alston supporter that "he was a Town
    Meeting member and he knew things the public didn't know [because]
    Alston won't allow [his personnel file] to be released to the
    - 13 -
    public."   The Town sought input about this incident from Alston's
    counsel but received no response.         Eventually, the Town concluded
    that Spiegel had not violated the Town's anti-discrimination/anti-
    retaliation policy.
    On January 13, 2015, Goldstein and Murphy met with Alston
    and his counsel.        They again requested that Alston submit to a
    reevaluation by Dr. Brown.         Alston refused and continued to press
    for paid leave. A brouhaha erupted over a statement that Goldstein
    construed as a threat and that Alston maintained was benign.             The
    meeting ended without any progress having been made.
    In    February,    Alston     sat     for   a   fitness-for-duty
    examination by Dr. Marilyn Price, a Town-retained psychiatrist
    (designated as such after Alston had demanded that the Town replace
    Dr. Brown).      The next day, Alston was placed on paid leave
    (apparently as a reward for his cooperation).          Dr. Price concluded
    that Alston could return to work so long as he committed to
    appropriate     treatment    and   the   Town    implemented   satisfactory
    stress-reducing accommodations.          She recommended three specific
    conditions:      that    Alston    receive     appropriate   mental   health
    treatment; that Alston undergo random drug screens; and that the
    Town work with Alston to identify accommodations to reduce his
    level of stress.     Even so, Alston and the Town failed to agree on
    a return-to-work plan.
    - 14 -
    In June of 2015, Alston wrote to the new Board chair
    (Neil Wishinsky), requesting a one-on-one meeting to discuss the
    "stalemate."      He stated that, although he had "always been willing
    to play by the rules," the Town was "not agreeing to make changes
    that will make the fire house safe for [him]."            Alston referenced
    the seminal 2010 voicemail, arguing that the promotion of Pender
    undermined the Town's professed "zero tolerance" policy toward
    racism.    He concluded by asking for an opportunity to be heard.
    Murphy — the Town's counsel — responded that she had advised
    Wishinsky against such a meeting.              Alston did not respond to
    Murphy.    Instead, Alston acknowledged receipt of Murphy's message
    in a letter to the Board.             In his letter, Alston declined the
    Town's    back-to-work     conditions    and   again   requested     a   hearing
    before     the     Board   on   his     discrimination     and     retaliation
    allegations.       Once again, it was Murphy who responded to Alston's
    request. She went on to emphasize the public safety considerations
    underlying Dr. Price's conditions and asked Alston to provide
    specific    reasons    for   disregarding      those   conditions.       Murphy
    received no reply to her letter.           In August and September, Chief
    Ford sought information from Alston about his current mental health
    treatment.       Alston did not respond to either inquiry.
    In November, a Town consultant released the results of
    a "racial climate" review.       The review found no significant areas
    of concern.
    - 15 -
    In February of 2016, Murphy requested proof of mental
    health treatment and instructed Alston to appear for a drug test.
    Alston neither acknowledged Murphy's request nor appeared for the
    scheduled drug test.     On February 16, the Board met and terminated
    Alston's paid leave for his failure to cooperate with return-to-
    work conditions.
    In March and April, the Town informed Alston that it had
    retained Charles Walker, a former MCAD chair, to hear Alston's
    concerns in front of the Board.        Alston refused to participate.
    On May 5, Murphy informed Alston's counsel that Chief Ford was
    available     to   discuss    reasonable    accommodations    and   sought
    information    about   Alston's   availability.     Once   again,   Murphy
    received no response.        In late May, Alston exhausted his accrued
    leave credits.
    In June of 2016, Acting Chief Robert Ward recommended
    Pender for a temporary promotion to deputy fire chief.              Pender
    appeared before the Board, and the Board decided to accept Ward's
    recommendation, noting that Pender had served out his discipline
    related to the voicemail incident.
    Alston did not respond to a July 21, 2016 letter from
    DeBow regarding possible modified duty, and he also did not appear
    for a drug test scheduled for the following August.          At the end of
    August, an outside hearing officer held a pre-termination hearing.
    Alston chose not to testify, not to call witnesses, and not to
    - 16 -
    submit any exhibits.          The hearing officer found just cause for
    termination of Alston's employment, and the Board voted to adopt
    the recommendation and to terminate Alston's employment.                      Alston
    appealed   his   termination         to   the     Massachusetts      Civil    Service
    Commission     (the   Commission),        which    denied   his      appeal   without
    holding an evidentiary hearing.                 In April of 2018, though, the
    state    superior     court    vacated      the    Commission's       decision    and
    remanded the matter for an evidentiary hearing.                   Following a ten-
    day evidentiary hearing, the Commission reversed Alston's ouster
    in February of 2019 and ordered him reinstated with back pay.                      In
    its decision and findings (the D&F), the Commission concluded that
    the Town's "own actions and inactions were the reasons that made
    it impossible for Firefighter Alston to return to work, which
    formed   the   basis    of    [the     Town's]     decision     to   terminate    his
    employment."     The superior court subsequently denied the Town's
    motion to stay the Commission's order pending the Town's appeal.
    And in August of 2019, the superior court affirmed the Commission's
    decision to reinstate Alston.             The Town's appeal was rejected by
    the Massachusetts Supreme Judicial Court on April 27, 2021.                       See
    Town of Brookline v. Alston, No. SJC-12974, 
    2021 WL 1619958
    , at *1
    (Mass. Apr. 27, 2021).
    During      the    latter      stages    of   this   jousting,     Alston
    repaired to the federal district court.                  He brought this suit in
    December of 2015, and it culminated (as relevant here) in the entry
    - 17 -
    of the summary judgment order that is now before us.                See Alston,
    
    2020 WL 1649915

    II. ANALYSIS
    Alston assigns error to the district court's entry of
    summary judgment in favor of the Town, the Board, and a cadre of
    Town officials sued both in their personal and official capacities.
    He argues that the record, properly configured, raises triable
    issues of fact as to the discriminatory and retaliatory nature of
    the defendants' actions.         Alston also challenges the district
    court's denial of his motion to void — on public policy grounds —
    settlement agreements that purport to forbid certain individuals
    from cooperating in the prosecution of Alston's case.
    We review a district court's entry of summary judgment
    de novo.   See Houlton Citizens' Coal., 
    175 F.3d at 184
    .               In that
    process,   we   evaluate   the   facts   of    record   in   the    light   most
    flattering to the nonmovant (here, Alston) and draw all reasonable
    inferences in that party's favor.          See 
    id.
          Summary judgment is
    appropriate only when the record, read as required, demonstrates
    that there is no genuine issue as to any material fact and that
    the moving party is entitled to judgment as a matter of law.                 See
    Fed. R. Civ. P. 56(a); Morelli v. Webster, 
    552 F.3d 12
    , 18 (1st
    Cir. 2009).      The denial of Alston's motion to void the non-
    cooperation     clauses     presents       a     question      of     contract
    - 18 -
    enforceability, which engenders de novo review.                       See S. Bay Bos.
    Mgmt. v. Unite Here, Local 26, 
    587 F.3d 35
    , 40 (1st Cir. 2009).
    A.    Claim Preclusion.
    At the outset, we think it necessary to clarify the scope
    of the record.         Specifically, the defendants contend that the
    relevant time frame from which we can pluck facts is limited to
    the period after the state court's 2014 judgment.                       Alston demurs,
    maintaining    that       earlier-occurring         facts      may   be    employed   to
    support his claims.            Because the resolution of this temporal
    dispute will shape our subsequent analysis, we tackle it first.
    1.        The    District       Court's    Treatment        of    State-Court
    Proceedings.    On July 8, 2014, the state superior court dismissed
    with prejudice Alston's 2013 lawsuit "as a sanction for Alston's
    failure to comply with discovery obligations."                        Alston, 
    2020 WL 1649915
    , at *1.       Four years later, the district court was tasked
    with evaluating how — if at all — that state-court judgment
    affected Alston's federal-court claims.                     See Alston v. Town of
    Brookline,    
    308 F. Supp. 3d 509
    ,    516   (D.    Mass.      2018).     The
    defendants invoked the doctrine of claim preclusion and "ask[ed]
    the court to excise the facts alleged in the first case from the
    present case."       
    Id. at 552
    .         Alston objected.
    The       district      court    sided    with     the     defendants:      it
    concluded "that the doctrine of claim preclusion does apply,
    because the claims at issue could have or should have been brought
    - 19 -
    in the prior action."        
    Id. at 517
    .      The court then went beyond
    what the defendants had requested, ruling that Alston could assert
    only "claims that post-date the final judgment" in the state-court
    suit.    
    Id.
    Alston moved for reconsideration, arguing (among other
    things) that because his state-court suit named only the Town as
    a defendant, his claims against the individual defendants could
    not be precluded.        See Alston v. Town of Brookline, No. 15-cv-
    13987, 
    2018 WL 3302995
    , at *1 (D. Mass. July 5, 2018). The district
    court denied Alston's motion, holding that "Alston may only assert
    claims against the defendants — both Town and individual — that
    have arisen after the date of the final judgment of the [state-
    court] case."       
    Id. at *2
    .
    The effect of these orders on Alston's claims is not
    entirely clear.        On the one hand, the district court did not
    explicitly expunge events prior to the 2014 judgment from the
    record (as requested by the defendants) but, rather, focused its
    order on "claims" that "could have or should have been brought."
    Alston, 308 F. Supp. 3d at 517.       Under this framework, mixed claims
    (that is, claims anchored both in facts occurring prior to the
    2014 cutoff date and in facts occurring thereafter) arguably could
    not have been brought in the state-court action and, thus, may
    have    survived.      On   the   other   hand,   the   district   court   did
    explicitly "[sustain] the defendant's objection" — an objection
    - 20 -
    that requested the court to bar all claims "alleg[ing] facts that
    pre-date the termination" of the state-court suit.               Id. at 516-
    17. Strengthening this implication, the district court later wrote
    that because "Alston was foreclosed from asserting in this case
    claims that were or were available to be asserted in the prior
    case," he could not "assert any claim arising from" incidents that
    occurred before the state court disposed of his original suit.
    Alston, 
    2020 WL 1649915
    , at *4 n.5.         Illustrating this point, the
    district court noted that the "Leave" incident had occurred in
    2013 and, thus, could not be relied upon in the federal-court
    action.    See 
    id.
    Claim    preclusion   is   strong   medicine   and   should   not
    casually be dispensed.      Although the district court suggested in
    dictum that its disposition of the case would not be different
    even if its claim preclusion ruling "was erroneous," 
    id.,
     we are
    not so sanguine.       The scope and validity of this ruling plainly
    affects the contours of the summary judgment record.               Thus, we
    train the lens of our inquiry on that ruling, reviewing it de novo.
    See Silva v. City of New Bedford, 
    660 F.3d 76
    , 78 (1st Cir. 2011).
    2. Why the District Court Erred. We apply Massachusetts
    law to determine the preclusive effect of the state-court judgment.
    See Torromeo v. Town of Fremont, 
    438 F.3d 113
    , 115-16 (1st Cir.
    2006).    In Massachusetts, "[c]laim preclusion makes a valid, final
    judgment conclusive on the parties and their privies, and prevents
    - 21 -
    relitigation    of    all   matters     that   were   or   could   have   been
    adjudicated in the action."       Kobrin v. Bd. of Regist. in Med., 
    832 N.E.2d 628
    , 634 (Mass. 2005) (quoting O'Neill v. City Manager of
    Cambridge, 
    700 N.E.2d 530
    , 532 (Mass. 1998)). In the circumstances
    at hand, claims based entirely on events preceding the state-court
    judgment could have been adjudicated in state court and                    are
    therefore barred. See id.; see also Heacock v. Heacock, 
    520 N.E.2d 151
    , 153 (Mass. 1988).       For claim preclusion to attach as to mixed
    claims, the defendants must establish that the prior judgment is
    one on the merits, that the parties to the prior and present suits
    are the same or in privity, and that the causes of action stated
    in the prior and present suits are the same.                See Kobrin, 832
    N.E.2d at 634.
    It cannot be gainsaid that the defendants have satisfied
    the first element.      The state court's dismissal with prejudice of
    Alston's suit operated as a final adjudication on the merits.              See
    Dep't of Revenue v. LaFratta, 
    562 N.E.2d 1352
    , 1355 (Mass. 1990)
    (explaining    that   "a    dismissal   with   prejudice    'constitutes    an
    adjudication on the merits as fully and completely as if the order
    had been entered after trial'" (quoting Boyd v. Jamaica Plain Coop.
    Bank, 
    386 N.E.2d 775
    , 778 n.8 (Mass. App. Ct. 1979))); see also
    Mass. R. Civ. P. 41(b)(2)-(3) ("On motion of the defendant,
    . . . the court may, in its discretion, dismiss any action for
    failure of the plaintiff to prosecute or to comply with these rules
    - 22 -
    or any order of court. . . . [Such] a dismissal . . . operates as
    an adjudication upon the merits.").
    The defendants' smooth sailing stops there.                For one
    thing, they encounter rough seas when the identity-of-parties
    element is inspected.            In the state court, Alston sued the Town
    alone.     By contrast, Alston's federal-court suit is directed not
    only against the Town but also against a bevy of individual
    defendants affiliated with the Town (who are named in both their
    individual      and        official   capacities).      As     official-capacity
    defendants,         these     individuals    present    no     barrier   to    the
    application of claim preclusion:                 we have held that "a public
    official, sued only in his official capacity, is a proxy for the
    government entity that employs him and is in privity with that
    entity."      Goldstein v. Galvin, 
    719 F.3d 16
    , 23 (1st Cir. 2013).
    For   claim    preclusion        purposes,   then,   the     identity-of-parties
    element is satisfied as to the claims against the Town and the
    individual defendants in their official capacities.
    But     as     individual-capacity     defendants,    these     Town
    officials stand on a different footing.              Because "[b]y definition,
    such a suit takes aim at the individual," those individual-capacity
    defendants are "not considered to be in privity with the government
    entity" with which they are affiliated (here, the Town).                      
    Id.
    Building on this foundation, we held in Goldstein that "a person
    who is sued in one capacity (whether official or individual) cannot
    - 23 -
    assert a defense of claim preclusion in a later action in which he
    is sued in a different capacity."           
    Id.
        Thus, "a person who has
    defended a suit brought against him in his official capacity is
    not protected by principles of claim preclusion from a subsequent
    suit brought against him by the same plaintiff[] in his individual
    capacity."     
    Id.
        It follows that none of Alston's claims against
    persons sued in their individual capacities are subject to claim
    preclusion,     and    the   district    court's     contrary      ruling   was
    incorrect.
    The defendants challenge this conclusion arguing that
    the "operative holding" in Goldstein was too narrow to be helpful.
    As they read it, Goldstein stands only for the proposition that
    "when a federal court considers the preclusive effect of an earlier
    state-court    judgment,     it   must   apply    that   state's    preclusion
    principles."     And in Massachusetts, they say, those principles
    demand a finding of claim preclusion.
    The defendants read Goldstein too grudgingly.            There, we
    assessed the preclusive effect of a state-court judgment when the
    state-court suit was against an individual in his official capacity
    and the subsequent federal suit named him only in his individual
    capacity.     See 
    id. at 22-23
    .      We concluded "that an official who
    has litigated [a claim] in his official capacity is not precluded
    from relitigation [of that claim] in his personal capacity."                
    Id. at 23
     (internal quotations omitted).             This conclusion is the law
    - 24 -
    of this circuit and, as such, it is binding upon us.          See United
    States v. Barbosa, 
    896 F.3d 60
    , 74 (1st Cir. 2018); Nevor v.
    Moneypenny Holdings, LLC, 
    842 F.3d 113
    , 125 (1st Cir. 2016).
    The individual defendants also suggest that Goldstein
    misconstrued Massachusetts law.        Even if that question were open
    to us — and it is not — the defendants do not argue that the wall
    that   Goldstein   erected   between     a   defendant's   official   and
    individual capacities does not exist.          Instead, they argue, in
    effect, that our conclusion in Goldstein was erroneous because,
    under Massachusetts preclusion principles, state courts do not
    require a showing of the identity of the parties.          Massachusetts
    courts, the defendants assert, apply the doctrine of non-mutual
    claim preclusion, which permits a person who was not a party in a
    prior suit to raise the defense of claim preclusion in a subsequent
    suit (such that litigation of a claim in one capacity may preclude
    relitigation in another capacity).
    The cases that the defendants cite for this suggestion
    are not in point.    Some of them do not apply Massachusetts law.
    See, e.g., Fidler v. E.M. Parker Co., 
    476 N.E.2d 595
    , 599-600
    (Mass. 1985) (determining preclusive effect of earlier federal-
    court judgment under federal claim-preclusion principles); Mancuso
    v. Kinchla, 
    806 N.E.2d 427
    , 434 (Mass. App. Ct. 2004) (same).
    Others turn on issue preclusion, not claim preclusion, see, e.g.,
    Martin v. Ring, 
    514 N.E.2d 663
    , 664 (Mass. 1987); Maher v. General
    - 25 -
    Motors Corp., 
    346 N.E.2d 833
    , 835 (Mass. 1976); Home Owners Fed.
    Sav. & Loan Ass'n v. Nw. Fire & Marine Ins. Co., 
    238 N.E.2d 55
    , 59
    (Mass. 1968), and this distinction makes a dispositive difference,
    see TLT Constr. Corp. v. A. Anthony Tappe & Assocs., Inc., 
    716 N.E.2d 1044
    , 1049 (Mass. App. Ct. 1999) ("Claim preclusion has as
    a prerequisite that there be an identity or privity of the parties
    to the present and prior actions, while issue preclusion requires
    [only] that the party against whom issue preclusion is asserted in
    the present action was a party or in privity with a party to the
    prior adjudication.").      The rest of the cases that the defendants
    cite    describe   claim   preclusion   generally    but   wholly   fail   to
    establish that, under Massachusetts law, a defendant who was
    neither a party nor in privity with a party in the earlier suit
    may invoke claim preclusion against a plaintiff.                See, e.g.,
    O'Neill, 700 N.E.2d at 532; Heacock, 520 N.E.2d at 152-53.
    We need not paint the lily.       Consistent with Goldstein,
    we hold that for a claim to be precluded by a previous state-court
    judgment, Massachusetts law requires the identity of parties.              See
    Korbin, 832 N.E.2d at 634.      The defendants sued in this action in
    their   individual   capacities   were     neither   parties   to   Alston's
    state-court suit nor in privity with such parties.             Accordingly,
    Alston's claims against those individual-capacity defendants are
    not subject to claim preclusion.
    - 26 -
    This leaves the possibility of claim preclusion against
    the   Town    and   the   individual       defendants    in    their   official
    capacities.     That possibility hinges on the third element of the
    claim preclusion framework:          the identity of the claims.       We bring
    that element front and center.
    Under Massachusetts law, "[a] claim is the same for
    [claim   preclusion]      purposes    if   it   is   derived   from    the   same
    transaction or series of connected transactions."               Saint Louis v.
    Baystate Med. Ctr., Inc., 
    568 N.E.2d 1181
    , 1185 (Mass. App. Ct.
    1991).   Several of the events important to Alston's federal-court
    claims undergirded Alston's state-court claims.                 In the state-
    court suit, Alston pleaded discrimination and retaliation claims
    and supported those claims with descriptions of the 2010 voicemail
    incident, Pender's subsequent promotions, and allegations that the
    Department's brass and the Town not only failed to take corrective
    action but also participated in further violations of his rights.
    Those allegations focused on the Town's actions aimed at isolating
    Alston from fellow firefighters.           Alston says that the Town mocked
    him by calling discrimination trainings "Alston trainings" or
    "Gerald trainings," by instructing other firefighters to "stay
    away from Alston" lest they risk being sued or fired, and by foot-
    dragging with respect to injured-on-duty benefits after Alston had
    been hurt at work.          According to Alston, the Town's actions
    resulted in firefighters shunning and ridiculing him.
    - 27 -
    Alston's allegations in federal court sweep much more
    broadly than his allegations in state court.         As an example, they
    go well beyond his relationship with his fellow firefighters.
    Alston alleges that the Town spoke to outside sources in order to
    discredit him, that the selectmen engaged Alston in bad faith after
    they placed him on paid administrative leave in February of 2015,
    and that the selectmen's insincere efforts to ensure that Alston
    would feel safe at work culminated in the termination of Alston's
    paid leave in February of 2016. As another example, Alston alleges
    in his federal-court suit that he was fired for discriminatory
    and/or retaliatory reasons — but that firing did not take place
    until well after 2014, and Alston's federal-court allegations are
    considerably more extensive than his state-court allegations of
    workplace disruption.         Where, as here, subsequent conduct is
    materially more extensive than the conduct underlying an earlier
    suit,   claim   preclusion    will    not   lie.   See    Walsh   v.   Int'l
    Longshoremen's Ass'n, Local 799, 
    630 F.2d 864
    , 873 (1st Cir. 1980).
    The sockdolager is that many of the allegations in
    Alston's    federal-court     complaint     post-date     the   state-court
    judgment.    For instance, the operative version of the federal-
    court   complaint   alleges    that   the   state-court   judgment     itself
    triggered further retaliation by the defendants because the state-
    court suit was (in their view) Alston's "last protection against
    termination."    Thereafter, Alston alleges, the Town ignored him,
    - 28 -
    cut off his pay, spoke negatively about him in public, and then
    cashiered him.     None of these allegations could conceivably have
    been included in the state-court suit because they refer to events
    that   had   not   then   happened.   Put   another   way,   the   present
    allegations "involve subsequent conduct, and thus lack sufficient
    identicality of causes of action with the earlier suit." González-
    Piña v. Rodríguez, 
    407 F.3d 425
    , 430 (1st Cir. 2005) (finding that
    claim preclusion did not apply where employee who returned to work
    after first suit was subjected to new conduct) (internal quotations
    omitted).
    The bottom line is that Alston's suspension without pay
    and his subsequent firing go significantly beyond the nucleus of
    operative facts alleged in the state-court case, both in time and
    scope.   And because suspension without pay and firing are alleged
    to be retaliatory consequences that were not — and could not have
    been — set out in the state-court complaint, the suit before us
    does not "seek[] redress for the same wrong[s]."             TLT Constr.
    Corp., 716 N.E.2d at 1051 (quoting Mackintosh v. Chambers, 
    190 N.E. 38
    , 39 (Mass. 1934)).      Therefore, the claims involved in the
    two suits are not identical.
    Against this backdrop, we hold that Alston's present
    claims against the Town and the official capacity defendants are
    - 29 -
    not precluded by the state-court judgment.            To the extent that the
    district court held to the contrary, its holding was in error.3
    3.    Some Final Words.         The doctrine of claim preclusion
    sieves claims, not facts. See Whole Woman's Health v. Hellerstedt,
    
    136 S. Ct. 2292
    , 2305 (2016).               Nor are we aware of any other
    authority that would bar the consideration of facts that occurred
    before the state-court judgment.             See 
    id.
     (citing Restatement of
    Judgments for proposition that materially changed circumstances
    post-judgment, "taken in conjunction with the antecedent facts,"
    may form the nucleus of a second action, Restatement (Second) of
    Judgments § 24, cmt. f (1980)).         In this suit, Alston complains of
    conduct that transpired over many years.              We conclude that he is
    not precluded either from bringing the present claims or from
    supporting those claims with facts that pre-date the state-court
    judgment.        To   the   extent   that    the   district   court's   rulings
    contravened these principles, those rulings were incorrect.
    3 There is one exception. Alston's claims against Selectwoman
    Mermell did not make it to the summary judgment stage.         The
    district court dismissed those claims because Mermell left the
    Board in 2013 and, as a result, no claim against her rested on
    facts that post-dated the state court's 2014 judgment. See Alston,
    
    2018 WL 3302995
    , at *2 n.1. Mermell is not listed on the docket
    as an appellee, and Alston offers no arguments against her on
    appeal.    What is more, when listing "the town officials who
    condoned and participated in the discrimination and retaliation"
    against him, he includes each of the individual defendants except
    Mermell. Accordingly, the district court's decision to dismiss
    the claims against her has not been challenged, and we need not
    consider it.
    - 30 -
    These errors have significant ramifications for this
    appeal.       The appropriateness of summary judgment depends, of
    course, on the existence vel non of genuine issues of material
    fact.     The district court's erroneous view of claim preclusion
    artificially        constrained   the    sources   that    it   was   willing   to
    consider in determining whether genuine issues of material fact
    existed.       We    must   proceed,     therefore,   to    evaluate    Alston's
    remaining claims of error against the full summary judgment record
    — a tableau that includes facts that occurred prior to the entry
    of the 2014 state-court judgment.            We turn next to that task.
    B.   Claims Against the Town and the Board (count 1).4
    Alston alleges that the Town and the Board are liable
    for racial discrimination against him in violation of the Equal
    Protection Clause.          See U.S. Const. amend. XIV, § 1.             He also
    alleges that the Town retaliated against him for protesting this
    discriminatory treatment, thereby abridging his First Amendment
    right to free speech.        See U.S. Const. amend. I.          These wrongs, he
    says, entitle him to recover damages under 
    42 U.S.C. §§ 1981
     and
    1983.    We examine his claims sequentially.
    4 Count 1 also contains allegations against Murphy and DeBow,
    but nearly identical allegations are contained in count 2. With
    respect to Murphy and DeBow, Alston's briefing does not distinguish
    between counts 1 and 2 but, instead, refers generally to those
    counts as his "discrimination and retaliation claims." For ease
    in exposition, we examine all of his claims against Murphy and
    DeBow in our subsequent discussion of count 2.

    1.      Equal Protection.          Alston invokes section 1983,
    asserting      that     the    defendants     violated      his    equal   protection
    rights.5      See Gagliardi v. Sullivan, 
    513 F.3d 301
    , 306 (1st Cir.
    2008) ("Section 1983 is a vehicle through which individuals may
    sue    certain       persons   for   depriving       them   of    federally   assured
    rights.").          To succeed on an equal protection claim, Alston must
    establish that, compared with others similarly situated, he was
    treated selectively and in a subpar manner based on impermissible
    considerations (such as race).              See Rubinovitz v. Rogato, 
    60 F.3d 906
    ,       909-10     (1st    Cir.   1995);    see    also       Ayala-Sepúlveda    v.
    Municipality of San Germán, 
    671 F.3d 24
    , 32 (1st. Cir. 2012) ("Some
    evidence       of     actual     disparate     treatment          is   a   'threshold
    requirement' of a valid equal protection claim" (quoting Est. of
    Bennett v. Wainwright, 
    548 F.3d 155
    , 167 (1st Cir. 2008).).                        "To
    5At the motion-to-dismiss stage, the district court
    considered whether the allegations in the operative complaint
    sufficed to establish municipal liability under section 1983. See
    Alston, 308 F. Supp. 3d at 532-34; see also Monell v. Dep't of
    Soc. Servs. of City of N.Y., 
    436 U.S. 658
    , 690 (1978). At that
    time, the Town and the Board conceded that the Board members were
    the final policymakers for purposes of liability anent Alston's
    employment. Alston, 308 F. Supp. 3d at 534. For that reason, the
    district court concluded that the allegations that the Board
    members' conduct "deprived Alston of constitutional rights is an
    acceptable method of establishing municipal liability under
    § 1983." Id.; see also Welch v. Ciampa, 
    542 F.3d 927
    , 942 (1st
    Cir. 2008) ("[A] single decision by a final policymaker can result
    in municipal liability.").     On appeal, the defendants do not
    dispute that Alston's allegations, if proven, would suffice to
    establish municipal liability. Accordingly, no Monell issue is
    before us.
    - 32 -
    put flesh upon the bare bones of this theory," a plaintiff's task
    is   "to   identify   and    relate      specific    instances     where   persons
    situated     similarly      'in   all     relevant    aspects'     were    treated
    differently."    Dartmouth Rev. v. Dartmouth Coll., 
    889 F.2d 13
    , 19
    (1st Cir. 1989) (quoting Smith v. Monsanto Chem. Co., 
    770 F.2d 719
    , 723 (8th Cir. 1985)).              Such relevant aspects include job
    "performance,       qualifications         and      conduct,     'without      such
    differentiating       or      mitigating         circumstances      that      would
    distinguish' their situations."            Smith v. Stratus Computer, Inc.,
    
    40 F.3d 11
    , 17 (1st Cir. 1994) (quoting Mitchell v. Toledo Hosp.,
    
    964 F.2d 577
    , 583 (6th Cir. 1992)).
    Alston has failed to satisfy this obligation. He neither
    alleges nor points to facts that identify non-black firefighters
    similarly situated to him, who did not experience the negative
    treatment and adverse employment actions to which he was subjected.
    Cf. Ayala-Sepúlveda, 671 F.3d at 32 (granting summary judgment
    when   plaintiff,     a    homosexual      man,     "present[ed]    no     evidence
    regarding, for example, instances in which heterosexual employees
    with similar rank and qualifications were not transferred").                    In
    his briefing, Alston does not make the slightest effort to identify
    any facts in the record that might show such a disparity in
    treatment.     We have warned before — and today reaffirm — that "a
    litigant has an obligation 'to spell out [his] arguments squarely
    and distinctly,' or else forever hold [his] peace."                 Rivera-Gomez
    - 33 -
    v. de Castro, 
    843 F.2d 631
    , 635 (1st Cir. 1988) (quoting Paterson-
    Leitch Co. v. Mass. Mun. Wholesale Elec. Co., 
    840 F.2d 985
    , 990
    (1st Cir. 1988)).    So it is here.   Consequently, we hold that the
    district court's grant of summary judgment on Alston's equal
    protection claim was unimpugnable.6      See Ayala-Sepúlveda, 671 F.3d
    at 32.
    2.    Section 1981.   We turn next to Alston's claims under
    
    42 U.S.C. § 1981
    .    The "exclusive federal remedy for violation of
    the rights guaranteed in § 1981 by state governmental units" is
    section 1983.    Buntin v. City of Boston, 
    857 F.3d 69
    , 70-71 (1st
    Cir. 2017) (quoting Jett v. Dallas ISD, 
    491 U.S. 701
    , 733 (1989)).
    Thus, a plaintiff "may not bring claims for damages under 
    42 U.S.C. § 1981
     against state actors."     
    Id. at 70
    .
    6 Alston's claims against the individual defendants include
    claims under 
    42 U.S.C. § 1983
    . As we noted in Spiegel, 988 F.3d
    at 574, the operative complaint does not explicitly invoke any
    particular constitutional provision in relation to the individual
    defendants.   The operative complaint does, however, invoke the
    Equal Protection Clause, see U.S. Const. amend. XIV, § 1, with
    respect to Alston's parallel allegations concerning the Town and
    the Board's allegedly discriminatory conduct. We therefore assume
    that his allegations of race discrimination against the individual
    defendants likewise arise under the Equal Protection Clause. See
    Spiegel, 988 F.3d at 574. So viewed, those claims suffer from the
    same evidentiary deficiency that dooms his counterpart equal
    protection claims against the Town and the Board: they lack any
    predicate showing of similarly situated firefighters who were
    spared the same sort of negative treatment and adverse employment
    actions of which Alston complains. Thus, we affirm the entry of
    summary judgment in favor of the individual defendants on these
    claims.
    - 34 -
    We are bound by Buntin as the law of the circuit, and
    Alston does not articulate any legal theory that would suffice to
    circumvent the Buntin limitation.            Accordingly, we affirm the
    district court's entry of summary judgment in favor of the Town
    and the Board with respect to Alston's section 1981 claims.                    By
    the same token, we affirm the district court's order granting
    summary judgment in favor of the individual defendants, in both
    their individual and official capacities, on those claims.                  See
    id. at 70, 76.    After all, those defendants are also state actors
    and they are alleged to have acted only within the realm of their
    official duties.    See id.      It follows that Alston's section 1981
    claims against them are barred.
    3. Section 1983 Retaliation. This brings us to Alston's
    claims for retaliation under 
    42 U.S.C. § 1983
    .                The gravamen of
    his claims is the contention that the defendants — the Town and
    the Board — retaliated against him for his exercise of his First
    Amendment rights.       To prevail, Alston — as a public employee —
    must establish that his expression involved matters of public
    concern,   that   his   interest    in    commenting   upon    those    matters
    outweighed the Town's interests in the efficient performance of
    its   public   services,   and     that    his   protected     speech    was   a
    substantial or motivating factor in the adverse employment actions
    that were visited upon him.        See Lewis v. City of Boston, 
    321 F.3d 207
    , 218 (1st Cir. 2003).     If Alston can make a prima facie showing
    - 35 -
    to this effect, the burden shifts to the defendants to demonstrate
    that they would have taken the same action regardless of Alston's
    speech.   See Collazo-Rosado v. Univ. of P.R., 
    765 F.3d 86
    , 95 (1st
    Cir. 2014).
    The affected defendants concede that Alston has made out
    a prima facie case of retaliation.          They insist, though, that they
    cooperated with Alston to facilitate his return to work and relied
    on Dr. Price's report in deciding to terminate Alston's employment.
    These actions, they say, make it pellucid that their decision to
    fire Alston was not anchored in a retaliatory rationale but,
    rather, that Alston's unfitness for duty was an independent reason
    for terminating his employment.
    In arguing that this explanation is a sham, Alston points
    primarily     to   the     D&F   (the    decision   and   findings    of    the
    Massachusetts      Civil    Service     Commission).      In   the   D&F,   the
    Commission found the defendants' proffered reasons for firing
    Alston to be pretextual.           Alston submits that if a jury were
    presented with the D&F — which rested on evidence that is largely
    included within the summary judgment record — it could reasonably
    conclude that the defendants acted in a retaliatory manner.                 The
    D&F should have been treated as admissible evidence in this case,
    - 36 -
    Alston insists, under Federal Rule of Evidence 803(8) and First
    Circuit precedent interpreting that rule.7
    Rule 803(8) crafts an exception to the hearsay rule, in
    certain      circumstances    and    subject    to   certain     conditions,    for
    "factual findings from a legally authorized investigation" by a
    governmental entity.        Fed. R. Evid. 803(8)(A)(iii).          Alston argues
    that       the   D&F   satisfies    these     criteria   and    that   comparable
    administrative         findings,    reached    (as   here)     after   adversarial
    hearings, have been admitted into evidence in other cases.                     See,
    e.g., Davignon v. Hodgson, 
    524 F.3d 91
    , 113 (1st Cir. 2008) ("The
    Supreme Court has interpreted [the] 'public records' exception to
    the hearsay rule broadly to include both conclusions and opinions
    of public offices and agencies" (quoting Patterson v. Mills, 64 F.
    App'x. 457, 462 (6th Cir. 2003).)); see also Beech Aircraft Corp.
    v. Rainey, 
    488 U.S. 153
    , 162 (1988).
    The defendants' initial objection is that Alston failed
    to advance this argument below.             Specifically, they contend that
    Alston "did not mention Fed. R. Evid. 803(8) and First Circuit
    precedent construing it" in the district court and, thus, waived
    any argument premised on those authorities.               The record, however,
    tells a different tale.
    Although the amici argued in their brief that the D&F should
    7
    be accorded preclusive effect, Alston expressly disavows that
    argument.
    - 37 -
    It is true that Alston did not make mention of either
    Rule 803(8) or First Circuit precedent interpreting it. But Alston
    justified his reliance on the D&F by citing case law for the
    proposition that the court could take judicial notice of it as a
    record and report of an administrative body.              In addition, Alston
    argued below that the D&F itself constituted evidence sufficient
    to   convince   a     reasonable     jury   to   find   that   the   defendants'
    explanation     was    a   pretext   for    discriminatory     and   retaliatory
    conduct.   He pointed out that, because the D&F was itself a product
    of an extensive evidentiary hearing and because that rational trier
    of fact found in his favor, a reasonable jury presented with
    essentially the same information could also find in Alston's favor.
    And in his opposition to the motion for summary judgment, Alston
    submitted that "[t]he facts presented at the civil service hearing,
    and the inferences drawn from those facts, were plainly sufficient
    to permit a reasonable fact finder — the chair of the Commission
    — to reject the Town's claim to have terminated Alston in good
    faith and for non-discriminatory and non-retaliatory reasons."
    Alston then suggested that "[i]t is not a leap to conclude that a
    reasonable jury, with the benefit of a full trial, could reject
    the same defenses proffered by the Defendants in this case.                   A
    jury would also be permitted to find, as did the Commission, that
    Alston's termination was retaliatory . . . on the basis of race."
    - 38 -
    There was more.   In that same opposition, Alston again
    argued that "after hearing all the evidence and making appropriate
    assessments of credibility, the Commission unequivocally rejected
    the Defendants' version of reality and sided with Alston.     It is
    simply not credible, therefore, for the Defendants to claim that
    a reasonable jury would somehow be compelled to find in the
    Defendants' favor on the same set of facts."
    The bottom line is that the defendants were clearly on
    notice of Alston's argument during the district court proceedings.
    In their rejoinder to Alston's opposition to summary judgment,
    they presented essentially the same arguments that they now make
    as to the admissibility vel non of the D&F.    Given these back-and-
    forth volleys, we think it is evident that Alston presented the
    D&F as a source of material facts for summary judgment purposes.
    That is essentially the same argument that he is making to us.
    Whether or not an issue is preserved in the trial court
    does not depend on what authorities the arguing party cites to
    that court.   See Metavante Corp. v. Emigrant Sav. Bank, 
    619 F.3d 748
    , 773 n.20 (7th Cir. 2010) (finding issue preserved because it
    was raised below and noting that "litigant may cite new authority
    on appeal"); United States v. Rapone, 
    131 F.3d 188
    , 196 (D.C. Cir.
    1997) (distinguishing between raising new issue and citing new
    authority on appeal).   Rather, preservation of the issue depends
    on whether the issue itself was presented face up and squarely in
    - 39 -
    the trial court.     See B & T Masonry Constr. Co. v. Pub. Serv. Mut.
    Ins. Co., 
    382 F.3d 36
    , 40 (1st Cir. 2004); Teamsters, Chauffeurs,
    Warehousemen & Helpers Union, Local No. 59 v. Superline Transp.
    Co., 
    953 F.2d 17
    , 21 (1st Cir. 1992).            Consistent with these
    principles, we hold that Alston adequately preserved the issue of
    whether the D&F should be considered as part of the summary
    judgment record.
    We turn next to the question of how the district court
    treated the D&F.      Although the court did not explicitly decide
    whether the D&F was specific and competent evidence, it ruled more
    globally that Alston "fail[ed] to cite competent, non-conclusory
    evidence in support of his objections to the defendants' cited
    factual evidence."     Alston, 
    2020 WL 1649915
    , at *3.      Later on, the
    court stated that Alston had not "pointed to admissible evidence
    that would support a factfinder's conclusion that the Town was
    punishing him in retaliation for his expressions of criticism."
    
    Id. at *5
    .    The only plausible reading of the district court's
    rescript is that the court must have decided, sub silentio, to
    exclude the D&F from the summary judgment record.           We review the
    district   court's    decision   to   exclude   the   D&F   for   abuse   of
    discretion.   See Udemba v. Nicoli, 
    237 F.3d 8
    , 14 (1st Cir. 2001).
    "Abuse-of-discretion review is respectful but appellate
    deference is not unbridled."      Corp. Techs., Inc. v. Harnett, 
    731 F.3d 6
    , 10 (1st Cir. 2013).      For example, a material error of law
    - 40 -
    categorically    constitutes   an   abuse   of   the   district   court's
    discretion.     See 
    id.
       Similarly, an abuse of discretion "occurs
    when a material factor deserving significant weight is ignored,
    when an improper factor is relied upon, or when . . . the court
    makes a serious mistake in weighing [the relevant factors]."          
    Id.
    (quoting Indep. Oil and Chem. Workers of Quincy, Inc. v. Procter
    & Gamble Mfg. Co., 
    864 F.2d 927
    , 929 (1st Cir. 1988)).
    We think that the court below abused its discretion in
    effectively excluding the D&F.         The defendants' argument, in
    essence, posits that Federal Rule of Civil Procedure 56(c)(1)
    requires parties to dispute facts in particular ways and that
    Alston did not refer to the D&F in such a way.            Although this
    argument makes clear that Alston did not dispute many of the
    statements of fact put forth by the defendants, nothing in Rule
    56(c)(1) informs a court about the admissibility of a particular
    piece of evidence.    Indeed, the rule itself contemplates proof of
    facts through, inter alia, "other materials."8
    8   Rule 56(c)(1) provides in pertinent part that
    A party asserting that a fact cannot be or is
    genuinely disputed must support the assertion
    by: citing to particular parts of materials
    in   the   record,   including   depositions,
    documents, electronically stored information,
    affidavits   or  declarations,   stipulations
    (including those made for purposes of the
    motion   only),   admissions,   interrogatory
    answers, or other materials . . . .
    Fed. R. Civ. P. 56(c)(1)(A).
    - 41 -
    Here, the most logical conclusion that can be drawn from
    a murky record is that the district court failed to give any weight
    to a proper factor in the decisional calculus:                       the D&F.     The
    court's only reference to the D&F was its conclusion that the D&F
    did not work any issue preclusion.               See Alston, 
    2020 WL 1649915
    ,
    at *3 n.2.       This conclusion, though, sheds no light on the
    admissibility     of    the     D&F.        An   agency's     findings     are    not
    inadmissible simply because they have no preclusive effect.                       Cf.
    Davignon, 
    524 F.3d at 113
     (upholding admission of agency decision
    under Rule 803(8) even though decision "involved a different issue
    and was not binding on the jury").
    To be sure, the Town and the Board argue in their
    appellate brief that the D&F is shot full of hearsay and is
    otherwise unreliable. These arguments are in service to an attempt
    to lay a foundation for the exclusion of the D&F as untrustworthy
    under Rule 803(8).           The fly in this particular ointment is that
    the    defendants      did    not   make     any   of     these      objections   to
    admissibility below.          Because the issue of whether the D&F should
    be excluded on this basis was not properly before the district
    court, we do not decide this issue.              "If any principle is settled
    in    this   circuit,   it     is   that,    absent     the   most    extraordinary
    circumstances, legal theories not raised squarely in the lower
    court cannot be broached for the first time on appeal."                   Superline

    Transp., 
    953 F.2d at 21
    .    For purposes of this appeal, then, any
    such objections are by the boards.9
    We hold that the district court abused its discretion in
    erroneously excluding the D&F at summary judgment because (the
    court thought) it lacked preclusive effect.   Even so, this holding
    does not end our inquiry.   It remains for us to determine whether
    a jury, armed with the D&F, reasonably could conclude that the
    defendants' stated reasons for terminating Alston's employment
    were pretextual.
    In conducting this appraisal, we remain mindful that
    there is no "mechanical formula" for establishing pretext.   Che v.
    Mass. Bay Transp. Auth., 
    342 F.3d 31
    , 39 (1st Cir. 2003).      One
    size does not fit all, and the inquiry into pretext is the kind of
    inquiry in which "everything depends on the individual facts."

    district court to exclude all or some of the D&F under Rule 803(8).

    New Eng. Tel. & Tel. Co., 
    909 F.2d 28
    , 34 (1st Cir. 1990) ("This
    court has consistently held that determinations of motive and
    intent, particularly in discrimination cases, are questions better
    suited for the jury, as proof is generally based on inferences
    that must be drawn, rather than on the proverbial 'smoking gun.'"
    (citation and quotation marks omitted)).
    Here, the record — properly constituted — contains an
    agency decision (the D&F) finding the defendants' reasons for
    firing Alston to be pretextual.       That agency decision tips the
    summary judgment scales and leads us to conclude that there was
    sufficient evidence from which a rational jury could find that the
    defendants' stated reason for firing Alston was only a pretext for
    discrimination.
    In reaching this conclusion, we take note that there are
    a number of routes through which a plaintiff can demonstrate
    pretext.     One such route is "by showing that the employer's
    proffered   explanation   is   unworthy   of   credence."   Reeves   v.
    Sanderson Plumbing Prods., Inc., 
    530 U.S. 133
    , 143 (2000) (quoting
    Texas Dep't of Cmty. Affs. v. Burdine, 
    450 U.S. 248
    , 256 (1981)).
    Another route allows a plaintiff to demonstrate pretext by showing
    "weaknesses, implausibilities, inconsistencies, incoherencies, or
    contradictions in the employer's proffered legitimate reasons"
    such that a factfinder could "infer that the employer did not act
    - 44 -
    for the asserted non-discriminatory reasons."        Hodgens, 
    144 F.3d at 168
    .   As we explain below, Alston's case travels down these
    routes.
    The defendants submit that Alston was fired because he
    was not fit for duty and because his non-cooperation and refusal
    to comply with the drug-testing condition rendered him unfit to
    return to work.     Alston says that these reasons were convenient
    fictions, and several facts (taken in the light most favorable to
    Alston) combine to support an inference that they were bogus.
    To    begin,     the   Commission   considered   whether   the
    defendants' proffered reasons for the adverse employment action
    were a "'mere pretext or device to get rid of' [Alston]."            It
    concluded that they were.        The D&F described how the conditions
    that triggered Alston's mental health issues — issues that the
    Town then used to question Alston's fitness for duty — were caused
    by the defendants.       According to the Commission, the Town "chose
    not to impose meaningful discipline" on Pender, elected to overlook
    the shunning and ignoring of Alston by other firefighters, and
    "promoted a false narrative that painted [Alston] as a paranoid
    employee who simply couldn't 'move on.'"
    The     conclusion     that   the   defendants   created   the
    conditions that left Alston unfit for duty is not plucked out of
    thin air but, rather, is bulwarked by other facts in the record.
    For instance, the information in the flyer describing Alston's
    - 45 -
    "going postal" comment was exaggerated, and Chief Skerry could not
    identify the source of the added information.           Moreover, Pender's
    statement describing new firefighters' surprise at how "something
    so benign" could be ongoing seven years later, could well suggest
    to a jury that the defendants have allowed a mischaracterization
    of the 2010 incident to flourish.
    The record facts could also suggest that the defendants
    were quick to minimize Alston's concerns with workplace hostility
    — concerns that he communicated to the Town as his reasons for not
    participating in the scheduled drug-testing.           As an example, DeBow
    was easily dissuaded, without a shred of proof, from the logical
    conclusion that the "Leave" message was rooted in discrimination
    or retaliation.        In marked contrast, she could not dismiss the
    "possibility" that the message was spawned by a fraternity despite
    there being absolutely no evidence to that effect.            And, finally,
    after Mermell left the Board in 2013, she posted a public apology
    to Alston, in which she lamented voting in favor of Pender's two-
    week suspension, called his punishment "inadequate," and admitted
    that she "accepted what [she] was told as fact" and that she failed
    "to   assert    that    a   bare-bones    punishment   fell   short   of   an
    appropriate response in the face of one of the most vile slurs."
    Mermell added that her failure to object to Pender's temporary
    promotion      was   "yet   another    message   regarding    the   lack   of
    seriousness and full understanding with which the Town leadership
    - 46 -
    was approaching this matter." All of these events took place prior
    to Dr. Price's 2015 report and could suggest to a jury that the
    defendants    were    unwilling       from    the   very    beginning     to    credit
    Alston's     complaints      of     race     discrimination        and    hostility,
    regardless    of     Alston's     fitness     to    perform     his    duties     as   a
    firefighter.
    Last — but surely not least — a jury reasonably could
    conclude on this record that the defendants' real motives were
    discriminatory       or   retaliatory.        Although      the    relevant     events
    spanned many years, the key fact is that the sequence of events
    was precipitated by a supervisor uttering a vicious racial slur.
    As the Fourth Circuit observed, "[p]erhaps no single act can more
    quickly alter the conditions of employment and create an abusive
    working environment than the use of an unambiguously racial epithet
    such as [the 'n-word'] by a supervisor in the presence of his
    subordinates."       Spriggs v. Diamond Auto Glass, 
    242 F.3d 179
    , 185
    (4th Cir. 2001) (quoting Rodgers v. W.-S. Life Ins. Co., 
    12 F.3d 668
    , 675 (7th Cir. 1993)).              So, too, "[n]o other word in the
    English language so powerfully or instantly calls to mind our
    country's    long     and    brutal    struggle        to   overcome     racism    and
    discrimination against African-Americans."                  Ayissi-Etoh v. Fannie
    Mae,   
    712 F.3d 572
    ,    580     (D.C.     Cir.    2013)     (Kavanaugh,      J.,
    concurring).       The record facts, taken in the light most conducive
    to Alston's claims, support serial conclusions:                   that the two-week
    - 47 -
    suspension of Pender was incommensurate with the repugnancy of
    Pender's   language;    that      Pender's   subsequent    promotions   were
    inconsistent   with    the   defendants'     professed    "zero   tolerance"
    policy toward racism; and that, for many years after the seminal
    incident, the defendants labored to protect — albeit clumsily —
    the supervisor who was in the wrong by nurturing the narrative
    that Alston was paranoid while Pender was remorseful.             Given the
    supportability of these conclusions, a jury reasonably could find
    that when the defendants realized that Alston would not budge,
    they chose to look for reasons to terminate his employment instead
    of taking action against Pender.
    Drawing all reasonable inferences in favor of Alston, we
    conclude that a jury could find that Alston's unfitness for duty
    was not the true reason for his firing.            Instead, a jury could
    find that the true reason for the firing was as a reprisal for
    Alston's    complaints       of     discrimination       and   retaliation.
    Accordingly, we vacate the district court's grant of summary
    judgment in favor of the Town and the Board on Alston's retaliation
    claims under section 1983 and remand those claims for further
    proceedings.
    C.   Remaining Claims Against Individual Defendants (count 2).
    We now reach Alston's remaining claims. The record makes
    manifest that even though all of the individual defendants may not
    have been involved in every significant event, each of them was
    - 48 -
    involved in at least one significant incident — investigating the
    voicemail fiasco, disciplining Pender, his subsequent promotions,
    the   inquiry   into   the   "Leave"   incident,   or    Alston's   firing.
    Alston's claims against them, brought pursuant to sections 1981
    and 1983, allege race-based discrimination and retaliation.10            We
    already have disposed of Alston's section 1981 claims and his
    section 1983 equal protection claims against these defendants, see
    supra Part II(B)(2) and note 6, and we need not repastinate that
    well-plowed ground.
    This   leaves     only   Alston's   section   1983   retaliation
    claims against certain Town officials (Nancy Daly, Sandra DeBow,
    Betsy DeWitt, Ben Franco, Kenneth Goldstein, Bernard Greene, Nancy
    Heller, Joslin Murphy, and Neil Wishinsky) in both their individual
    and official capacities.       With respect to these claims, the Town
    officials rely heavily on the district court's decision to consider
    only facts arising after the state-court judgment.              Because the
    district court's temporal limitation was in error, see supra Part
    10Alston also brought a claim against these defendants for
    conspiracy to deprive him of the equal protection of the laws.
    See 
    42 U.S.C. § 1985
    . The district court entered summary judgment
    against Alston on this claim. Alston, 
    2020 WL 1649915
    , at *5. In
    his appellate briefing, Alston makes no substantive reference to
    that ruling.   Consequently, we deem any claim of error waived.
    See United States v. Zannino, 
    895 F.2d 1
    , 17 (1st Cir. 1990)
    ("[T]he settled appellate rule [is] that issues adverted to in a
    perfunctory manner, unaccompanied by some effort at developed
    argumentation, are deemed waived.").    It follows that only his
    section 1983 retaliation claims remain for our review.
    - 49 -
    II(A), the wind has been taken out of the sails of many of the
    Town officials' arguments.         We consider what remains of their
    asseverational array.11
    The   Town   officials    primarily   argue    that   Alston   has
    failed to raise a genuine issue of material fact as to any of the
    elements of his section 1983 First Amendment retaliation claims.
    See Lewis, 
    321 F.3d at 218
    .     They first argue that Alston has not
    spoken on an issue of public concern.       See 
    id.
         Specifically, they
    assert that after the state-court judgment, Alston was on sick
    leave, pending psychiatric clearance.           In their view, Alston's
    grievances from and after that time focused on the outcome of the
    prior litigation — not a matter of public concern.
    This is little more than gaslighting. The Town officials
    concede that Alston previously protested racial discrimination.
    Relatedly, they concede that the right to protest discrimination
    is "inherently" a matter of public concern.        See Connick v. Myers,
    
    461 U.S. 138
    , 148 n.8 (1983).      It follows inexorably that once the
    district court's erroneous temporal limitation has been corrected,
    Alston's speech satisfies the "public concern" element of his
    section 1983 retaliation claims.
    11The individual defendants raise several arguments that are
    duplicative of those raised by the Town and the Board, including
    arguments in support of affording claim-preclusive effect to the
    state-court judgment and arguments in support of excluding the D&F
    from the summary judgment record. For the reasons discussed above,
    see supra Part II(A), we find those arguments unpersuasive.
    - 50 -
    Next, the Town officials contend that Alston's interest
    in his speech was outweighed by the Town's interests in the
    efficient performance of its public services.       See Lewis, 
    321 F.3d at 218
    .    This contention, too, rests on a mischaracterization of
    Alston's speech as speech "about previously litigated and adjudged
    claims."    As we have pointed out, Alston's speech can fairly be
    found to be speech against racial discrimination; so the question
    for us is whether Alston's interest in speaking against racial
    discrimination in the Department is outweighed by the Town's
    interests in the efficient discharge of public services.
    In balancing these interests, we are committed to the
    proposition that "[s]o long as employees are speaking as citizens
    on matters of public concern, they must face only those speech
    restrictions that are necessary for their employers to operate
    efficiently and effectively."       Garcetti v. Ceballos, 
    547 U.S. 410
    ,
    419 (2006).   Such balancing "requires a hard look at the facts of
    the case, including the nature of the employment and the context
    in which the employee spoke."        Decotiis v. Whittemore, 
    635 F.3d 22
    , 35 (1st Cir. 2011) (quoting Davignon, 
    524 F.3d at 104
    ).           We
    proceed to take that "hard look," viewing the facts (as the summary
    judgment standard demands) in the light most favorable to Alston.
    See O'Connor v. Steeves, 
    994 F.2d 905
    , 917 (1st Cir. 1993).
    After   Alston   first    became   concerned   about   racial
    discrimination in the Department, he spoke behind closed doors
    - 51 -
    with   senior     firefighters.      He   then    spoke      directly    with   his
    supervisors.      After Pender was promoted, Alston continued to voice
    his    objections    to     the   defendants'     allegedly         discriminatory
    conduct.     It was only after Alston reasonably perceived that the
    Department had fumbled the ball that he began to speak more
    publicly    (with   other    firefighters      and    with    outside    parties).
    Alston's quiet contacts with his supervisors adequately evinces
    that reporting discrimination in the Department does not per se
    disrupt     the   Department's     delivery      of    its     important      public
    services.    Given these facts, it strains credulity to insist that
    muzzling     employees      who   wish    to     speak       out    against     race
    discrimination is essential for the efficient operation of the
    Department.       See Garcetti, 
    547 U.S. at 418-19
    .                It follows that
    Alston has satisfied the second element of his                       section 1983
    retaliation claims.
    As to the third and last element, four of the Town
    officials — DeBow, Murphy, DeWitt, and Goldstein — argue that they
    did not engage in conduct that can be said to constitute an adverse
    employment action under section 1983.            See Lewis, 
    321 F.3d at 218
    .
    "[T]he 'adverse employment action' inquiry in the section 1983
    context focuses on whether an employer's acts, viewed objectively,
    place substantial pressure on the employee's political views."
    Barton v. Clancy, 
    632 F.3d 9
    , 29 (1st Cir. 2011) (quoting Bergeron
    v. Cabral, 
    560 F.3d 1
    , 8 (1st Cir. 2009)).                   In undertaking this
    - 52 -
    tamisage, we look to "whether the defendants' acts would have a
    chilling effect on the employee's exercise of First Amendment
    rights."   
    Id.
       As such, the "pertinent question" is whether the
    actions of these four defendants comprise the kind of actions that
    "would deter 'a reasonably hardy individual[]' from exercising his
    constitutional      rights."      
    Id.
       (quoting    Agosto-de-Feliciano     v.
    Aponte-Roque, 
    889 F.2d 1209
    , 1217 (1st Cir. 1989) (en banc)).
    Alston contends that these four defendants are liable
    because they "allowed Alston's pay to terminate in 2014."                  But
    Alston elsewhere asserts that his pay ended in October of 2014
    because "he had exhausted all of his available leave."               In this
    respect, Alston is hoist by his own petard — especially since the
    record   contains    no   facts   sufficient   to    cast   doubt   upon   his
    "exhaustion" assertion.        Nor does anything in the record suggest
    that one or more of these four defendants had the slightest effect
    on the cessation of Alston's paid leave. Because Alston has failed
    to provide any factual plinth for a finding that DeBow, Murphy,
    DeWitt, or Goldstein engaged in an adverse employment action within
    the purview of section 1983, we affirm the district court's entry
    of summary judgment in favor of these four defendants, in both
    their official and individual capacities, on the section 1983
    retaliation claims.
    The remaining Town officials            (Daly, Franco, Greene,
    Heller, and Wishinsky) argue that, although their firing of Alston
    - 53 -
    constitutes an adverse employment action, they did not vote to
    cashier him in retaliation for his protected speech.    See Lewis,
    
    321 F.3d at 218
    .   In support, they insist that the real reason for
    Alston's firing was his unfitness for duty.      But as we already
    have indicated, the record discloses a genuine issue of material
    fact as to whether that proffered reason for Alston's firing was
    pretextual.   See supra Part II(B)(2).       As a result, summary
    judgment cannot rest on this ground.
    Alternatively, the remaining Town officials submit that
    they are entitled to qualified immunity with respect to Alston's
    individual-capacity claims.    To determine if a public official is
    entitled to qualified immunity, an inquiring court engages in a
    "two-step pavane."    Alfano v. Lynch, 
    847 F.3d 71
    , 75 (1st Cir.
    2017).   At the first step, the court must determine "whether the
    plaintiff's version of the facts makes out a violation of a
    protected right."     
    Id.
         At the second step, the court must
    determine "whether the right at issue was 'clearly established' at
    the time of defendant's alleged misconduct."   
    Id.
     (quoting Matalon
    v. Hynnes, 
    806 F.3d 627
    , 633 (1st Cir. 2015)).   Because qualified
    immunity is an affirmative defense to liability, the burden is on
    the defendants to prove the existence of circumstances sufficient
    to bring the defense into play.    See DiMarco-Zappa v. Cabanillas,
    
    238 F.3d 25
    , 35 (1st Cir. 2001).
    - 54 -
    Here, however, we must address the qualified immunity
    issue within the limits of the arguments presented to us on appeal.
    In their appellate argument, the remaining Town officials (Daly,
    Greene, Heller, Franco, and Wishinsky) do not clearly separate out
    either the first prong of the inquiry or the various components of
    the second prong.        Nor do they attempt to analyze either prong
    with respect to each defendant (individually). Instead, they argue
    generally that they did not violate Alston's First Amendment rights
    without pausing to distinguish between and delineate the two
    prongs.
    Given this superficial presentation, we cannot at this
    juncture conclude that the remaining Town officials are entitled
    to qualified immunity.       The limitations of the record and of the
    defendants' arguments stand in the way.         It follows that we must
    vacate the district court's entry of summary judgment on the claims
    against the remaining Town officials.
    We   add   a   coda.    To   the   extent   the   remaining   Town
    officials focus on the first prong of qualified immunity in their
    appellate brief, that reliance is mislaid.            They have made, at
    most, generalized and non-specific arguments with respect to each
    individual defendant.      Since we already have held that Alston has
    survived summary judgment on the merits of his First Amendment
    retaliation claims, see supra Part II(C), such arguments are
    insufficient to ground a conclusion that Alston's version of the
    - 55 -
    facts falls short of working a violation of his constitutional
    rights.     See Alfano, 847 F.3d at 75.
    We also think it useful to comment upon the second prong
    of the qualified immunity inquiry.          In their appellate brief, the
    Town officials cite that prong and state that "the law must have
    been sufficiently clear that 'any reasonable official in the
    defendant's position would have known that the challenged conduct
    is   illegal   "in   the    particular   circumstances   that   he   or   she
    faced."'"      They also discuss the         Pickering balancing of       the
    interests, see Pickering v. Bd. of Educ. of Twp. High Sch. Dist.
    205, 
    391 U.S. 563
    , 568 (1968), and their claimed justifications
    for the termination of Alston's employment.              But they do not
    explain why these elements of Alston's First Amendment retaliation
    claims fail one or more components of the second prong.          Given the
    lack of clarity as to the arguments actually being made, we cannot
    now conclude that the remaining Town officials are entitled to
    qualified immunity.        The entry of summary judgment in their favor
    on Alston's section 1983 free-speech retaliation claims, in both
    their individual and official capacities, must, therefore, be
    vacated.
    This does not mean, of course, that the district court
    cannot explore the qualified immunity issue in all its aspects on
    remand.    For instance, the district court may entertain successive
    motions for summary judgment, see FDIC v. Kooyomjian, 
    220 F.3d 10
    ,
    - 56 -
    16 (1st Cir. 2000), or address the issue at a subsequent stage of
    the litigation, see Guzmán-Rivera v. Rivera-Cruz, 
    98 F.3d 664
    , 669
    (1st Cir. 1996) (noting that even though defendants had waived
    defense of qualified immunity at summary judgment stage, defense
    remained available for subsequent stage of litigation).             We leave
    these matters to the district court's informed discretion, and we
    take no view of the future disposition of the issue.
    D.    Non-Cooperation Agreements.
    There is one loose end.          After Alston commenced this
    action, the Town entered into settlement agreements with three
    black men who had asserted claims against it.12                 Each of the
    agreements contained a similarly worded non-cooperation clause,
    which     barred   the    claimant   from   "voluntarily    cooperat[ing]   or
    assist[ing] any person or entity . . . in the prosecution of any
    claims against the defendants."         One of the agreements went so far
    as to prohibit cooperation with "Gerald Alston in connection with
    the pending federal court complaint."            The prohibition contained
    in the agreements, however, was not absolute:              the agreements did
    not prohibit the claimants "from testifying truthfully under oath
    12  Alston's first amended complaint (FAC) added seven
    plaintiffs to this action, but the district court severed the added
    plaintiffs. Although the added plaintiffs are not parties to this
    appeal, it should be noted that two of the black men with whom the
    Town settled were named as plaintiffs in the FAC. The Town also
    settled with another black man who sought to sue separately for
    assault and battery.
    - 57 -
    if compelled to do so via subpoena or court order in a legal
    proceeding" or from "cooperating with any federal or state agency
    investigation not initiated by a Party."
    When Alston learned of the agreements, he moved for an
    order voiding the clauses prohibiting voluntary cooperation with
    a party in his position as against public policy.             The district
    court denied the motion, and Alston assigns error.
    Alston's principal plaint is that the non-cooperation
    clauses are against public policy. In support, he relies primarily
    on our decision in EEOC v. Astra USA, Inc., 
    94 F.3d 738
     (1st Cir.
    1996).      There,    we    concluded   that   agreements   that    prohibit
    cooperation with government agencies are void on public policy
    grounds.    See 
    id. at 745
    .       This case, however, is a horse of a
    different   hue:      the    clauses    at   issue   explicitly    allow   the
    signatories to cooperate with agency investigations and to provide
    information pursuant to subpoenas or court orders.                 Astra is,
    therefore, inapposite.
    In a final attack on these agreements, Alston argues
    that, in pursuing his civil rights claims, he is acting as a
    private attorney general.        As a result, he suggests, his claims
    "implicate[] the public interest in safeguarding civil rights."
    Alston's reasoning is flawed. It would essentially ban commonplace
    non-disclosure clauses from settlement agreements in all civil
    rights actions.      Such a broad proscription finds no support in the
    - 58 -
    case    law.      To   the   contrary,     "public    policy    strongly   favors
    encouraging      voluntary    settlement     of    employment    discrimination
    claims."       
    Id. at 744
    .
    We will "rarely" invalidate settlement agreements on
    public policy grounds.        Bandera v. City of Quincy, 
    344 F.3d 47
    , 52
    (1st Cir. 2003).        This case falls within the general rule, not
    within the long-odds exception to it.                 The Town's use of non-
    cooperation       clauses     as    a    bargaining     chip     in   settlement
    negotiations may be controversial, but we are not prepared to break
    new ground and hold that a municipality's use of such clauses is
    against public policy.         We therefore affirm the district court's
    denial of Alston's motion to void the non-cooperation clauses.
    III. CONCLUSION
    We need go no further.        Just as large oaks from single
    acorns grow, so too — as this case illustrates — sprawling lawsuits
    can grow from a single, highly charged racial slur.               And this suit
    is not yet at an end.              For the reasons elucidated above, the
    judgment of the district court is affirmed in part and vacated in
    part.      Specifically, we vacate the district court's grant of
    summary judgment as to Alston's retaliation claims under section
    1983 against the Town and the Board.              We also vacate the district
    court's judgment as to Alston's section 1983 retaliation claims
    against Daly, Greene, Heller, Franco, and Wishinsky, in their
    personal and official capacities. The case is remanded for further
    - 59 -
    proceedings consistent with this opinion.   All parties shall bear
    their own costs.
    So Ordered.
