    The Freedom of Information Act (FOIA) makes government records accessible
    to the public, including organizations like Plaintiff Rocky Mountain Wild. But this
    access is not limitless. The statute instructs government agencies to use reasonable—
    Appellate Case: 21-1169    Document: 010110791250       Date Filed: 12/30/2022     Page: 2
    not the utmost—efforts to produce responsive records upon request. Beyond that,
    FOIA also exempts nine categories of records from public disclosure.
    Plaintiff requested and received voluminous records under FOIA, but now
    asserts Defendants United States Forest Service (“USFS”) and United States
    Department of Agriculture (“USDA”) abused these statutory limitations to hide
    information about projects that harm the environment. The district court rejected
    Plaintiff’s speculative theory and found USFS’s efforts to comply with Plaintiff’s
    FOIA request reasonable.1 Our jurisdiction arises under 
    28 U.S.C. § 1291
    . We
    affirm.
    I.
    For years the parties have litigated the propriety of a proposed development in
    the Wolf Creek Ski Area—which the USFS manages. The proposed development is a
    plan for highway access known as “the Village at Wolf Creek Access Project.”
    Plaintiff challenges this plan because of alleged environmental risks to the
    surrounding national forest. The highway-access litigation continues, but relevant
    here is a 2018 FOIA request Plaintiff submitted asking Defendant for “all agency
    records regarding the proposed Village at Wolf Creek Access Project.”
    Plaintiff’s request caused an enormous undertaking by Defendant. The request
    sought “all agency records” about the project. The breadth of the request first
    1
    Although Plaintiff sued both the Forest Service and the Department of
    Agriculture, the Forest Service plays the most prominent role in this dispute. So for
    efficiency, we use “Defendant” or “USFS” to refer to the Forest Service.
    2
    Appellate Case: 21-1169     Document: 010110791250        Date Filed: 12/30/2022        Page: 3
    required Defendant to determine the relevant period during which its employees
    would have created responsive documents so it could direct those employees to
    search their files within that timeframe. Then Defendant also narrowed the request’s
    scope to include only documents Defendant had not already given Plaintiff,
    documents Defendant had not made public, and documents not statutorily exempt
    from disclosure.
    Defendant next had to find employees who might possess responsive records.
    Defendant determined that twenty-seven employees were substantially involved in
    the Village at Wolf Creek Access Project during the relevant timeframe and likely
    possessed responsive records. All but two of those employees worked in Colorado.
    Defendant allowed the employees to search their own files using custom search
    terms, reasoning that each employee would know the best search terms to find
    responsive documents. The employees reported how they searched their files and
    listed their individual search terms. Between the twenty-seven employees, they
    searched their files with more than two dozen different search terms, including
    variations of similar terms. Some of the twenty-seven employees handed off the
    search to their administrative assistants but still specified the search terms their
    administrative assistants used. Those who searched looked in different locations,
    such as physical hard-copy files, external and internal computer hard drives, and
    emails, including attachments, within their archive system. Finally, most employees
    searched twice for documents, and all the selected employees searched for responsive
    records after March 1, 2019, to make sure none showed up at the last minute.
    3
    Appellate Case: 21-1169     Document: 010110791250       Date Filed: 12/30/2022   Page: 4
    After collecting documents from the twenty-seven employees, a team of five
    Forest Service officials worked full-time for months to review the produced
    documents.2 The team organized documents into three groups: (1) nonresponsive,
    which they removed; (2) responsive but either produced before from a past FOIA
    request, outside the window Defendant calculated, or exempt under FOIA, which
    they also removed but listed the exempt documents in an index; and (3) responsive
    and not previously produced, outside the timeframe, or exempt under FOIA, which
    they gave to Plaintiff. As the team compiled disclosable responsive documents, it
    sent groups of them to Plaintiff in “rolling productions.”
    Over the course of a year, Defendant organized twenty-seven rolling
    productions to Plaintiff after identifying 140,637 responsive pages in 14,740 records.
    Defendant tried to produce these documents in a way Plaintiff preferred, such as
    reproducing documents as individual PDF files and reproducing those documents a
    third time as searchable PDFs once Plaintiff objected to the non-searchable format.
    At Plaintiff’s insistence, Defendant also created an almost 800-page “Vaughn index”
    to inventory the thousands of agency records FOIA exempted from disclosure (7,757
    in total). See Vaughn v. Rosen, 
    484 F.2d 820
    , 827 (D.C. Cir. 1973) (establishing that
    an agency can list exempt documents in an index to allow a court to consider the
    agency’s justifications for exempting them more easily). Defendant even hired an
    outside contractor to help prepare the Vaughn index because so many privilege issues
    2
    Other Forest Service employees helped part-time.
    4
    Appellate Case: 21-1169    Document: 010110791250       Date Filed: 12/30/2022    Page: 5
    came into play and Defendant wanted to make sure it had properly withheld or
    redacted documents. Defendant submitted declarations detailing its months-long
    search effort.
    While Defendant gathered responsive documents to include in the rolling
    productions, Plaintiff sued Defendant in federal court for allegedly missing statutory
    deadlines, conducting an inadequate search, and improperly withholding or redacting
    documents. During the litigation, Defendant started producing documents to
    Plaintiff. In one production, Defendant mistakenly included two documents not
    properly redacted and asked Plaintiff to return or destroy the documents and provided
    Plaintiff with properly redacted replacements. But Plaintiff refused. So Defendant
    moved the district court to order Plaintiff to return or destroy the documents. The
    court granted Defendant’s motion, directing Plaintiff to remove the documents from
    any online locations (another organization had posted the documents on its Facebook
    page) and return or destroy them.
    Later, the parties each moved for summary judgment. Defendant argued that
    its declarations describe how its employees reasonably searched for responsive
    documents and prove that the agency reasonably applied FOIA exemptions to redact
    parts of or withhold entire records. Plaintiff countered that Defendant had not proven
    it conducted a FOIA-compliant search or met the standard to exempt documents in
    whole or in part from production. The district court granted Defendant’s summary-
    judgment motion. It found that Defendant reasonably searched for records to comply
    with the FOIA request and adequately justified why it redacted or withheld certain
    5
    Appellate Case: 21-1169    Document: 010110791250        Date Filed: 12/30/2022    Page: 6
    records. Plaintiff appeals the summary-judgment decision and the order to return the
    improperly redacted documents.
    II.
    We review a grant of summary judgment in FOIA cases de novo if the district
    court’s decision “had an adequate factual basis.” Jordan v. U.S. Dep’t of Just., 
    668 F.3d 1188
    , 1192 (10th Cir. 2011) (quoting Audubon Soc’y v. U.S. Forest Serv., 
    104 F.3d 1201
    , 1203 (10th Cir. 1997). The government can develop an adequate factual
    basis by providing a Vaughn index, which an agency typically puts together to allow
    the court to review the agency’s nondisclosures. See Anderson v. Dep’t of Health &
    Hum. Servs., 
    907 F.2d 936
    , 942 (10th Cir. 1990). The agency bears the burden of
    justifying its nondisclosures. Friends of Animals, 
    15 F.4th 1254
    , 1260 (10th Cir.
    2021) (citing Herrick v. Garvey, 
    298 F.3d 1184
    , 1190 (10th Cir. 2002).
    A court should grant summary judgment when “the movant shows that there is
    no genuine dispute as to any material fact and the movant is entitled to judgment as a
    matter of law.” Fed. R. Civ. P. 56(a). A mere scintilla of evidence supporting the
    nonmovant’s position will not create a genuine issue of material fact; the fact issue
    must make it so that a reasonable jury could find for the nonmovant. Herrick, 
    298 F.3d at 1190
    . Because the district court granted summary judgment in Defendant’s
    favor, “we review the record and all reasonable inferences . . . drawn therefrom in the
    light most favorable to [Plaintiff].” See Trentadue v. Integrity Comm., 
    501 F.3d 1215
    , 1226 (10th Cir. 2007) [“Trentadue I”].
    6

    III.
    Plaintiff challenges the district court’s decision on four grounds. First,
    Plaintiff claims the court applied the standard of review incorrectly by improperly
    deferring to Defendant’s declarations. Second, Plaintiff argues that the court
    wrongly found that Defendant conducted a reasonable search for records. Third,
    Plaintiff asserts that the court erred in determining that Defendant validly withheld or
    redacted documents under certain FOIA exemptions. And last, Plaintiff appeals the
    district court’s order allowing Defendant to claw back inadvertent disclosures USFS
    made during one of its rolling productions to Plaintiff.
    Congress enacted FOIA to facilitate public access to federal agency records
    and information. Friends of Animals, 15 F.4th at 1260 (citing NLRB v. Robbins Tire
    & Rubber Co., 
    437 U.S. 214
    , 221 (1978)). The statute favors disclosure. NLRB, 
    437 U.S. at 220
    . But it also exempts nine categories of records from disclosure for
    confidentiality and privacy reasons. 
    Id.
     at 220–21; 
    5 U.S.C. § 552
    (b). With this
    statutory framework in mind, we address Plaintiff’s assertions.3
    3
    We also grant Plaintiff’s motion to file a supplemental appendix. Plaintiff
    failed to include all the relevant docket entries when it first filed its appendix like the
    Federal Rules of Appellate Procedure and our local rules require. See Lincoln v.
    BNSF Ry. Co., 
    900 F.3d 1166
    , 1189 (10th Cir. 2018) (citing Fed. R. App. P. 30
    (a)(1); 10th Cir. R. 10.3(A)). While an appellant who produces an inadequate
    appendix “does so at his peril,” Dikeman v. Nat’l Educators, Inc., 
    81 F.3d 949
    , 955
    (10th Cir. 1996) (citation omitted), we see no reason not to allow the supplement
    because it results in no prejudice to either party. See infra at 23–24.
    7
    Appellate Case: 21-1169    Document: 010110791250        Date Filed: 12/30/2022    Page: 8
    A.
    “In any FOIA action challenging an agency decision to withhold records, the
    district court reviews de novo the agency’s decision not to disclose.” See Herrick,
    
    298 F.3d at 1189
    . Although Plaintiff recognizes that the district court stated the
    correct standard, Plaintiff asserts that the court improperly deferred to Defendant’s
    declarations and failed to conduct a true de novo review. Plaintiff claims the district
    court applied a “bad faith standard to shield litigation declarations from scrutiny.”
    This standard, according to Plaintiff, required Plaintiff to show the agency’s bad faith
    to disprove the declarations’ contents instead of the court analyzing the declarations’
    veracity.
    The district court applied no such standard. Rather, it applied a good-faith
    presumption to the declarations as our precedent directs. See Trentadue v. F.B.I.,
    
    572 F.3d 794
    , 808 (10th Cir. 2009) [“Trentadue II”] (quoting SafeCard Servs., Inc. v.
    SEC, 
    926 F.2d 1197
    , 1200 (D.C. Cir. 1991)). This presumption “essentially requires
    us to credit the agency’s sworn statements” absent contrary evidence. Stevens v.
    U.S. Dep’t of State, 
    20 F.4th 337
    , 342–43 (7th Cir. 2021). In Trentadue II, we
    adopted the D.C. Circuit’s rule that courts should give agency declarations a
    presumption of good faith that a FOIA plaintiff cannot rebut by merely speculating
    about the possibility of other documents somewhere. 
    572 F.3d at 808
    .
    The district court correctly presumed, then, that Defendant submitted its
    declarations in good faith because “declarations and affidavits are the widely
    accepted, even preferable, means for an agency to respond to concerns about the
    8
    Appellate Case: 21-1169    Document: 010110791250        Date Filed: 12/30/2022     Page: 9
    adequacy of a FOIA search.” 
    Id. at 807
    . And although the court discussed bad faith,
    it did so only to address Plaintiff’s numerous accusations of Defendant’s supposed
    bad faith. The court rejected those accusations because Plaintiff could not cite
    supporting caselaw or provide examples of Defendant’s bad faith. Simply put, as
    Plaintiff recognizes, without contrary evidence or proof of inconsistencies,
    Defendant’s detailed declarations comply with FOIA. See 
    id. at 807
     (quoting
    Rugiero v. U.S. Dep’t of Just., 
    257 F.3d 534
    , 547 (6th Cir. 2001)).
    Thus, Plaintiff needed to present specific, nonspeculative, countervailing
    evidence or evidence of inconsistencies to rebut the good-faith presumption. As
    discussed more below, Plaintiff failed to do so. Meanwhile, the district court
    appropriately discussed why it applied the presumption of good faith to Defendant’s
    declarations and then explained why it rejected each of Plaintiff’s arguments about
    supposed countervailing evidence of Defendant’s bad faith. The district court even
    considered the sufficiency of the agency’s declarations even though Plaintiff did not
    challenge their sufficiency. We thus reject Plaintiff’s argument that the court failed
    to conduct de novo review merely because it presumed Defendant presented its
    declarations in good faith.
    B.
    Next, Plaintiff argues that the district court erred by concluding Defendant
    engaged in reasonable search efforts. We agree with the district court that Defendant
    put forth reasonable efforts to comply with Plaintiff’s FOIA request.
    9
    Appellate Case: 21-1169     Document: 010110791250         Date Filed: 12/30/2022   Page: 10
    FOIA does not specify how hard an agency must look for requested records.
    Trentadue II, 
    572 F.3d at 797
    . But we have joined other circuits that have adopted
    the “reasonableness rule.” 
    Id.
     (listing circuits). The rule requires agencies to show
    that they reasonably tried to produce responsive records. 
    Id.
     (citing 
    5 U.S.C. § 552
    (a)(3)(C)). Their search must be “reasonable in scope and intensity” and need
    not turn up “every nonexempt requested document regardless of the cost of locating
    it.” 
    Id.
     That is why we focus on the agency’s search process, not the outcome. 
    Id.
    To that end, the “issue is not whether any further documents might conceivably exist
    but rather whether the government’s search for responsive documents was adequate.”
    
    Id.
     (alteration in original) (quoting Weisberg v. U.S. Dep’t of Just., 
    705 F.2d 1344
    ,
    1351 (D.C. Cir. 1983)). The reasonableness inquiry focuses on the probability that
    the search will discover responsive documents, the availability of other search
    methods, and the feasibility of those alternative methods. See id. at 798 (quoting
    Davis v. Dep’t of Just., 
    460 F.3d 92
    , 105 (D.C. Cir. 2006)). We also consider the
    case’s circumstances when analyzing the search. 
    Id.
     at 797 (citing Weisberg, 
    705 F.2d at 1351
    ).
    Plaintiff accuses the agency of not using effective search terms, excluding
    employees likely to have responsive records, avoiding searching the agency’s
    Washington D.C. offices, and ignoring devices likely to have responsive records.
    Plaintiff insists that the district court “uncritically accept[ed]” Defendant’s
    declarations to find the search reasonable despite these alleged failures. But courts
    generally resolve FOIA cases on summary judgment based on affidavits or
    10
    Appellate Case: 21-1169    Document: 010110791250        Date Filed: 12/30/2022    Page: 11
    declarations. See World Publ’g Co. v. U.S. Dep’t of Just., 
    672 F.3d 825
    , 832 (10th
    Cir. 2012) (first citing Trentadue II, 
    572 F.3d at
    807–08; then Wood v. F.B.I., 
    432 F.3d 78
    , 85 (2d Cir. 2005)). Not to mention, we prefer that agencies use declarations
    or affidavits to ease concerns about a FOIA search’s adequacy. Trentadue II, 
    572 F.3d at 807
    . And we apply a presumption of good faith to an agency’s affidavits or
    declarations, which Plaintiff cannot rebut by merely speculating about the existence
    of other documents. 
    Id.
     at 808 (citing SafeCard, 
    926 F.2d at 1200
    ).
    Indeed, we routinely rely on declarations to make sure an agency fulfilled its
    FOIA duties. For example, in Trentadue II, we thought that the F.B.I.’s searches
    were “very thorough.” 
    572 F.3d at 807
    . The F.B.I. attested in declarations that it had
    searched its indices, manually searched two files, and indexed the entire principal file
    about the event at issue. 
    Id.
     The only task the F.B.I. did not do would have required
    manually searching through one million pages of the principal file, which would take
    “thousands of hours of work”—an effort we described as “unreasonably
    burdensome.” 
    Id.
     Because the F.B.I.’s declarations “provide[d] an internally
    consistent and uncontradicted record” of its search efforts, we determined that the
    plaintiff could not justify the additional discovery he requested. 
    Id. at 808
    . Thus,
    like the plaintiff in Trentadue II, Plaintiff must come forward with “countervailing
    evidence or apparent inconsistency of proof” to rebut the good-faith presumption for
    Defendant’s detailed declarations. See 
    id. at 807
     (quoting Rugiero, 
    257 F.3d at 547
    ).
    Otherwise, the court has no reason not to believe the agency’s sworn statements.
    11
    Appellate Case: 21-1169    Document: 010110791250        Date Filed: 12/30/2022      Page: 12
    Plaintiff asserts that the agency did not use effective search terms, excluded
    from its search employees likely to have responsive records, avoided searching the
    agency’s Washington D.C. offices, and ignored devices likely to have responsive
    records. These failures, Plaintiff complains, caused the agency’s search to violate its
    duties under FOIA. We disagree.
    The agency allowed its employees to come up with their own search terms
    while looking for documents about the project. In Plaintiff’s view, this led to
    inconsistent search results that likely left out responsive records. The Seventh
    Circuit recently rejected a similar attack on a State Department document search.
    See Stevens, 20 F.4th at 343. There, a FOIA plaintiff objected to the State
    Department allowing its officers to decide what to search based on their familiarity
    with the Department’s way of keeping records. Id. The court determined that the
    Department sufficiently detailed its account of search methods and found the
    methods reasonable. Id. at 343–44; see also Inter-Coop. Exch. v. U.S. Dep’t of
    Com., 
    36 F.4th 905
    , 911 (9th Cir. 2022) (recognizing the discretion that agencies
    enjoy in crafting search terms designed to identify responsive records because they
    know best how they keep their own files and what vocabulary they use for certain
    projects).
    We reach the same conclusion here. Defendant’s decision to allow its
    employees to customize the terms they employed to search their own records is not
    inherently unreasonable, especially given that Defendant listed the terms each
    employee used. And that list included more than two dozen search terms with
    12
    Appellate Case: 21-1169     Document: 010110791250        Date Filed: 12/30/2022     Page: 13
    different variations of similar terms. Cf. Inter-Coop. Exch., 36 F.4th at 911–12
    (finding an agency’s choice to use just two search terms insufficient because those
    terms could not have found responsive records to both requests the plaintiff
    submitted, did not adequately reflect the breadth of the requests, and did not include
    variant terms). Although Defendant did not use precisely the terms Plaintiff would
    have used to look for the same information, Plaintiff presents no reasoned authority
    demonstrating the unreasonableness of Defendant’s search terms. We therefore
    reject Plaintiff’s argument to the extent that it rests on Defendant’s allegedly
    unreasonable search terms.
    Plaintiff further alleges that Defendant purposefully excluded other employees
    likely to have responsive records. According to Plaintiff, the district court
    improperly deferred to Defendant’s identification of which employees may have
    responsive records. Defendant attested in its declarations that it chose employees
    based on who created documents about the project or whether relevant documents
    were routed through those employees. Plaintiff argues that the district court ignored
    the possibility that Defendant may have omitted other employees, but Plaintiff does
    not identify who Defendant overlooked.
    Plaintiff asserts that any person listed on the Vaughn index should have
    searched their files as well. Plaintiff directs us to three individuals who allegedly
    possess responsive documents but did not search for them. The first two people
    Plaintiff names no longer work for the agency, but the employees who took over their
    positions did search their records to comply with the FOIA request. So that leaves
    13
    Appellate Case: 21-1169     Document: 010110791250        Date Filed: 12/30/2022    Page: 14
    one person—the District Ranger on the Divide District of the Rio Grande National
    Forest—who Plaintiff identifies as possibly possessing responsive records that
    Defendant could have included in its search. Defendant did not ask this employee to
    search her files because she has worked so little on the project that Defendant did not
    expect her to have responsive records. Plus, Defendant says, any responsive records
    she may possess would come up in other employees’ searches who were more
    substantially involved in the project.
    Plaintiff insists that leaving out any employees who potentially have
    responsive documents frustrates “a FOIA search designed to find all agency records.”
    But Plaintiff misunderstands the standard—a FOIA search need not locate every
    conceivable responsive record no matter the cost. See Trentadue II, 
    572 F.3d at 797
    .
    Plaintiff identifies only persons whose files contain documents duplicative of those
    searched for by other employees. Defendant’s choice to exclude those persons was
    not unreasonable.
    Plaintiff also objects to the employees who recruited their assistants to search
    their records for them. Plaintiff reasons that if each employee supposedly knew their
    own records well enough to come up with their own search terms, then they should
    have searched the files themselves. But Plaintiff offers no evidence that the
    employees’ assistants did not know the best way to find responsive records. Nor
    does Plaintiff claim that the assistants used deficient search terms. Instead, Plaintiff
    implicitly speculates that the employees themselves would have used different terms
    if they had personally searched their files. Plaintiff’s lack of evidence showing the
    14
    Appellate Case: 21-1169    Document: 010110791250       Date Filed: 12/30/2022   Page: 15
    inadequacy of having an assistant search files for responsive documents dooms its
    argument.
    Plaintiff also appears to object—on a numerical basis—to Defendant’s
    decision to involve twenty-seven (and not more) employees to conduct the search.
    These conclusory assertions do not rebut the good-faith presumption we apply to
    Defendant’s declarations explaining why it did not include more employees in the
    search. See Trentadue II, 
    572 F.3d at 808
    .
    Next, Plaintiff contends that the agency might have found additional
    responsive records in its Washington, D.C. offices had it only required more
    employees to search their documents. But Defendant’s declarations explain that
    although it considered employees across offices, most employees it identified as
    likely to have responsive records worked in Colorado because the project involves
    federal land in that state. Plaintiff responds by pointing out that Defendant’s Vaughn
    index proves that the D.C. offices contain responsive records. True enough. But
    even if there are responsive documents in Washington D.C., there is no evidence in
    the record before us that they are not duplicative or otherwise exempt from
    production. And even if there are more documents in Washington D.C., their mere
    existence does not mean that Defendant’s search was unreasonable.
    Finally, Plaintiff objects to Defendant’s choice of which devices to search and
    where to search on those devices. Plaintiff apparently expected the employees to
    describe where they searched, whether they searched the entirety of each document
    or device, and how they made sure they searched every possible responsive document
    15
    Appellate Case: 21-1169    Document: 010110791250        Date Filed: 12/30/2022     Page: 16
    they possessed. This goes far beyond the reasonableness standard; FOIA searches
    need only be “reasonable in scope and intensity.” See Trentadue II, 
    572 F.3d at 797
    .
    The record in this case demonstrates a herculean effort by Defendant to comply with
    Plaintiff’s requests. Defendant deployed a team of employees who worked full-time
    for months locating and reviewing responsive records; produced 14,740 documents
    totaling 140,637 pages from the personal files of twenty-seven identified custodians;
    and hired an electronic discovery specialist to provide Plaintiff an 800-page Vaughn
    index containing nearly 8,000 individual entries. To hold that such an effort was
    unreasonable could result in such a burden on agencies that they could not both
    comply with FOIA and complete the core functions of their jobs.
    As part of its final point, Plaintiff objects to the employees not searching their
    work cellphones, which Plaintiff says might contain responsive text messages, notes,
    or records in other email accounts. This complaint misses the mark for a few
    reasons. For one, not every Forest Service employee uses a work cellphone. And
    those that do have a work cellphone sync the phone’s email account with their work
    computer’s email account, meaning any computer search would have caught
    responsive emails on employees’ phones. For another, Plaintiff does not pinpoint
    any responsive documents that the phones possess. Rather, Plaintiff speculates that
    the phones contain “potentially responsive” records. This speculation fails in the
    face of Defendant’s declarations explaining that Defendant entrusted its employees to
    decide where to search because they know best where responsive records might be
    located, and that they did not search their cellphones because they did not expect
    16
    Appellate Case: 21-1169    Document: 010110791250        Date Filed: 12/30/2022      Page: 17
    their phones to have any responsive records that a computer search would not have
    already found. Because Plaintiff does not rebut this explanation with concrete
    evidence to the contrary, we presume Defendant trusted its employees in good faith.
    See Trentadue II, 
    572 F.3d at 808
    . And without countervailing evidence suggesting
    that employees worked on the project using personal text messaging or other email
    accounts, we similarly presume the employees chose not to search their text messages
    and personal email accounts in good faith. 
    Id. at 808
    . So considering all the places
    the employees did search, their good-faith decision to not include personal text
    messages and email accounts in their search does not render Defendant’s search
    unreasonable, either.
    Ultimately, Plaintiff’s arguments rely on speculation. While Plaintiff remains
    unsatisfied, it offered no evidence to show what additional documents other
    employees or offices possibly possessed. At the same time, Defendant’s declarations
    describe a thorough investigation for employees who might have responsive records,
    detailed lists of how each employee searched their own records, and explanations of
    how the team who received those records separated them out to respond to the FOIA
    request. Based on Defendant’s declarations and Plaintiff’s failure to rebut them, we
    agree with the district court that Defendant performed an adequate search. Again, we
    focus not on whether “any further documents might conceivably exist,” but whether
    the government adequately searched for responsive documents. Trentadue II, 
    572 F.3d at 797
    . At bottom, Plaintiff failed to produce evidence sufficient to create a
    17
    Appellate Case: 21-1169     Document: 010110791250        Date Filed: 12/30/2022      Page: 18
    genuine issue for trial on whether the agency reasonably tried to produce responsive
    documents, making summary judgment on this issue proper.
    C.
    Plaintiff also challenges the district court’s determination that Defendant
    properly withheld or redacted documents under certain FOIA exemptions. Plaintiff
    first protests Defendant’s decision to hire an outside contractor to help prepare the
    Vaughn index. But Plaintiff did not dispute Defendant’s outside contractor below,
    forfeiting the issue. See Richison v. Ernest Grp., 
    634 F.3d 1123
    , 1128 (10th Cir.
    2011) (explaining that “if the theory simply wasn’t raised before the district court, we
    usually hold it forfeited”); Appellant’s App. Vol. I at 208–54. And Plaintiff does not
    argue on appeal that the district court committed plain error. We thus do not consider
    the issue because Plaintiff waived it by not arguing for plain-error review after
    forfeiting it. See Richison, 
    634 F.3d at 1128
    , 1131 (citing McKissick v. Yuen, 
    618 F.3d 1177
    , 1189 (10th Cir. 2010) (clarifying that a party waives plain-error review of
    a forfeited argument by failing to explain how the forfeited argument survives plain-
    error review)).
    Plaintiff waived the issue about Defendant preparing an insufficient Vaughn
    index as well. Unlike Plaintiff’s outside-contractor argument, which it forfeited at
    the district court, Plaintiff did contest the index entries below. But to preserve issues
    for appeal, a party must draft arguments that go beyond general claims of error,
    Garrett v. Selby Connor Maddux & Janer, 
    425 F.3d 836
    , 841 (10th Cir. 2005), and
    include the “contentions and reasons for them, with citations to the authorities and
    18
    Appellate Case: 21-1169      Document: 010110791250        Date Filed: 12/30/2022    Page: 19
    parts of the record on which the appellant relies.” Fed. R. App. P. 28(a)(8)(a)
    (emphasis added).
    Despite this standard, Plaintiff argues only generally that Defendant created an
    insufficient Vaughn index. Plaintiff does not name even one specific entry where
    Defendant failed to include the necessary information to justify applying a FOIA
    exemption. Still, Plaintiff argues it sufficiently briefed the issue by objecting below
    to groups of entries that lacked information and then citing those objections in its
    appellate briefs. These objections also do not identify individual entries; Plaintiff
    merely groups allegedly deficient entries into categories with hundreds of entries in
    each.
    But “[j]udges are not like pigs, hunting for truffles buried in briefs.” Gross v.
    Burggraf Const. Co., 
    53 F.3d 1531
    , 1546 (10th Cir. 1995) (quoting United States v.
    Dunkel, 
    927 F.2d 955
    , 956 (7th Cir. 1991)). “[A]ppellants, rather than courts of
    appeals, [must] ferret out and articulate the record evidence considered material to
    each legal theory advanced on appeal.” Conto v. Concord Hosp., Inc., 
    265 F.3d 79
    ,
    81–82 (1st Cir. 2001). So without a specific reference to the purportedly insufficient
    entries, we will not scour the record to determine whether evidence exists that might
    require the case to go to a jury. Gross, 53 F.3d at 1546 (quoting Thomas v. Wichita
    Coca-Cola Bottling Co., 
    968 F.2d 1022
    , 1025 (10th Cir. 1992)).
    Plaintiff claims Defendant’s Vaughn index contains 4,110 deficient entries.
    Plaintiff apparently invites us to comb through the entire index to see if we agree.
    We decline the invitation. If Plaintiff wanted to challenge the index’s sufficiency,
    19
    Appellate Case: 21-1169    Document: 010110791250       Date Filed: 12/30/2022    Page: 20
    Plaintiff needed to specifically reference the problematic entries and explain what
    makes them insufficient.4 Its failure to do so means Plaintiff waived this issue. See
    Garrett, 
    425 F.3d at 841
     (quoting Utahns for Better Transp. v. U.S. Dep’t of Transp.,
    
    305 F.3d 1152
    , 1175 (10th Cir. 2002) (noting that a party waives issues inadequately
    briefed).
    Plaintiff also quarrels with the district court’s exemption analysis. FOIA
    requires agencies to hand over any requested agency records unless an exemption
    listed in 
    5 U.S.C. § 552
    (b) prevents their disclosure. Prison Legal News v. Exec.
    Off. for U.S. Att’ys, 
    628 F.3d 1243
    , 1251 (10th Cir. 2011) (citing U.S. Dep’t of Just.
    v. Tax Analysts, 
    492 U.S. 136
    , 150–51 (1989)). So as we consider Defendant’s
    justifications for invoking exemptions, we keep in mind that we must construe FOIA
    broadly and apply any exemptions narrowly. Trentadue I, 
    501 F.3d at 1226
    . Indeed,
    “the required balance is not an even one. Because FOIA’s core purpose is to shed
    light on the government’s performance of its duties,” we broadly construe the statute
    to favor disclosure. Friends of Animals, 15 F.4th at 1267. So we start with a
    “presumption of disclosure.” Id. At the same time, “we recognize that the FOIA
    exemptions serve important interests.” Id. at 1261 (citing John Doe Agency v. John
    Doe Corp., 
    493 U.S. 146
    , 152 (1989)).
    4
    Plaintiff did not specify which entries are allegedly deficient in the
    proceedings below, either. The district court randomly spot-checked some entries
    and found them “reasonably clear, specific, and detailed.”
    20
    Appellate Case: 21-1169    Document: 010110791250         Date Filed: 12/30/2022     Page: 21
    Although Defendant invoked many FOIA exemptions, Plaintiff challenges
    only Exemption 5’s application on appeal. This exemption “excuses disclosure of
    ‘inter-agency or intra-agency memorandums or letters which would not be available
    by law to a party other than an agency in litigation with the agency.’” Trentadue I,
    
    501 F.3d at 1226
     (quoting 
    5 U.S.C. § 552
    (b)(5)). Put differently, Exemption 5
    protects documents a privilege would cover in a civil proceeding involving an
    agency. Id.; see also F.T.C. v. Grolier Inc., 
    462 U.S. 19
    , 26–27 (1983) (“Exemption
    5 incorporates the privileges which the Government enjoys under the relevant
    statutory and case law in the pretrial discovery context.”) (emphasis omitted)
    (quoting Renegotiation Bd. v. Grumman Aircraft Eng’g Corp., 
    421 U.S. 168
    , 184
    (1975)).
    A court can look to, among other things, detailed affidavits for the factual
    basis necessary to decide whether the agency sufficiently justified withholding or
    redacting records. See Anderson, 907 F.2d at 942. As long as the affidavits
    reasonably specify how the documents fall within the exemption, the agency satisfies
    its burden under FOIA. Hull v. I.R.S., U.S. Dep’t of Treasury, 
    656 F.3d 1174
    , 1177
    (10th Cir. 2011) (quoting Quiñon v. F.B.I., 
    86 F.3d 1222
    , 1227 (D.C. Cir. 1996)).
    But affidavits that “merely parrot” the statute’s language or supply conclusions
    without explanation do not suffice. Anderson, 907 F.2d at 942 (quoting Carter v.
    U.S. Dep’t of Com., 
    830 F.2d 388
    , 393 (D.C. Cir. 1987)).
    Plaintiff challenges Defendant’s invocation of Exemption 5 on two grounds.
    First, Plaintiff argues Defendant never specified the harm it would suffer if it had to
    21
    Appellate Case: 21-1169     Document: 010110791250          Date Filed: 12/30/2022     Page: 22
    disclose each exempt entry like FOIA requires. Second, it asserts that Defendant did
    not prove the attorney-client privilege or the work-product doctrine applied to each
    entry in the index under this exemption.
    Plaintiff also waived its second theory, but for a different reason than the first
    two waived issues. Plaintiff did not include all the relevant docket entries in its
    appendix like the Federal Rules of Appellate Procedure and our local rules require.
    See Lincoln v. BNSF Ry. Co., 
    900 F.3d 1166
    , 1189 (10th Cir. 2018) (first citing Fed.
    R. App. P. 30 (a)(1); then 10th Cir. R. 10.3(A)). So it tried to add a third volume to
    its appendix when filing its reply brief. This third volume contained one document:
    Plaintiff’s reply to the cross-motion for summary judgment in the district court.
    Plaintiff needed this reply to disprove Defendant’s allegation that Plaintiff waived
    any challenge to the elements of the attorney-client privilege or the work-product
    doctrine by not mentioning this issue below or arguing for plain-error review in its
    opening brief. Turns out, Plaintiff did brief this issue below, but just in a reply. So
    the district court did not consider the issue, likely because Plaintiff raised it for the
    first time in a reply. See Appellant’s App. Vol. II at 364 (“Plaintiff does not
    specifically challenge the withholdings under any particular theory of exemption; in
    other words, Plaintiff does not argue that Defendant has failed to demonstrate a
    particular element of the attorney-client privilege, for example.”). After all, reply
    briefs “do not provide the moving party with a new opportunity to present yet another
    issue for the court’s consideration.” Home Design Servs., Inc. v. B & B Custom
    22
    Appellate Case: 21-1169     Document: 010110791250         Date Filed: 12/30/2022    Page: 23
    Homes, LLC, 
    509 F. Supp. 2d 968
    , 971 (D. Colo. 2007) (quoting Pacific Gas and
    Elec. Co. v. U.S., 
    69 Fed. Cl. 784
    , 817 (Fed. Cl. 2006).
    So Plaintiff asks us to consider an issue (1) asserted once in a reply brief
    below (2) that the district court did not consider, yet (3) not challenged for plain error
    on appeal, let alone (4) in its original appendix. These failures “surely mark[ ] the
    end of the road for an argument for reversal not first presented to the district court.”
    Richison, 
    634 F.3d at 1131
    ; see also Singleton v. Wulff, 
    428 U.S. 106
    , 120 (1976)
    (“It is the general rule, of course, that a federal appellate court does not consider an
    issue not passed upon below.”).
    Plaintiff’s remaining argument—that Defendant insufficiently justified its
    exemptions by failing to prove harm for each entry in the Vaughn index—fails, too.
    Congress amended FOIA in 2016 to allow an agency to withhold information only if
    the agency “reasonably foresees that disclosure would harm an interest protected by
    an exemption.” 5 U.S.C § 552(a)(8)(A)(i). The D.C. Circuit has interpreted this
    amendment to impose a duty on agencies to show not only that an exemption applies,
    but also how disclosure would harm the interest sought to be protected by that
    exemption, at least in the context of withholdings based on the deliberative-process
    privilege. See Reps. Comm. for Freedom of the Press v. F.B.I., 
    3 F.4th 350
    , 369–70
    (D.C. Cir. 2021).
    Plaintiff insists that Defendant could not invoke Exemption 5 without also
    explaining how disclosure would harm the agency. We have yet to decide whether
    § 552(a)(8)(A)(i) requires agencies to show not just that an exemption applies but
    23
    Appellate Case: 21-1169    Document: 010110791250       Date Filed: 12/30/2022    Page: 24
    also how sharing the information would harm the interest protected by that
    exemption. But we need not do so here. Like the district court determined, even if
    that heightened burden applies, Defendant made the required showing of harm.
    Defendant asserted that it applied Exemption 5 to withhold or redact documents
    covered by the attorney-client privilege, the work-product doctrine, and the
    confidential-information privilege.
    The reasons for protecting attorney communications are long-established. See
    Swidler & Berlin v. United States, 
    524 U.S. 399
    , 403 (1998) (first citing Upjohn Co.
    v. United States, 
    449 U.S. 383
    , 389 (1981); then Hunt v. Blackburn, 
    128 U.S. 464
    ,
    470 (1888)) (“The attorney-client privilege is one of the oldest recognized privileges
    for confidential communications.”); see also Hickman v. Taylor, 
    329 U.S. 495
    , 510
    (1947) (recognizing the work product doctrine). Defendant attested in declarations
    that documents withheld or redacted under Exemption 5 mainly involved attorney-
    client communications. The declarations detail the kinds of documents involved,
    including drafts of legal documents, and explain why disclosure of that information
    would harm Defendant. It should surprise no one that Defendant and Plaintiff, who
    have been litigating the Village at Wolf Creek Access Project for years, have
    privileged materials related to this dispute. And Defendant would suffer harm if
    Plaintiff got its hands on those documents. The attorney-client privilege and work-
    product doctrine prevent that harm. For this reason, Congress created Exemption 5.
    See Hunton v. U.S. Dep’t of Just., 
    590 F.3d 272
    , 278–79 (4th Cir. 2010) (explaining
    that Congress drafted Exemption 5 to prevent private parties from using the FOIA to
    24
    Appellate Case: 21-1169    Document: 010110791250          Date Filed: 12/30/2022     Page: 25
    deprive the government of the work-product and attorney-client protections otherwise
    available to it in litigation). So Defendant’s declarations sufficiently show that the
    agency would suffer harm from disclosing documents protected by either the
    privilege or the doctrine. See, e.g., F.T.C., 
    462 U.S. at 23
     (recognizing that
    “Congress had the attorney’s work-product privilege specifically in mind when it
    adopted Exemption 5”) (quoting NLRB v. Sears Roebuck & Co., 
    421 U.S. 132
    , 154
    (1975)). Thus, the district court properly determined that Defendant met its
    Exemption 5 burden.
    D.
    Plaintiff lastly appeals the district court’s order that Plaintiff return or destroy
    two improperly redacted documents Defendant inadvertently disclosed. Plaintiff
    argues that the documents were no longer confidential or privileged because another
    organization posted them online and thus the district court could not order their
    return.5 In support, Plaintiff cites Anderson, where we said that because text taken
    from journal publications “appear to be in the public domain, no meritorious claim of
    confidentiality” can exist to assert a FOIA exemption. 907 F.2d at 952 (citing
    C.N.A. Fin. Corp. v. Donovan, 
    830 F.2d 1132
    , 1154 (D.C. Cir. 1987)). Plaintiff fails
    to explain, however, the similarity between a deliberate journal publication and the
    inadvertently disclosed confidential or privileged information here. It is one thing to
    5
    Plaintiff actually argues that it posted the documents online, but the
    screenshot it submitted as proof shows another organization posting the FOIA
    production. In fact, that same page lists Plaintiff as a “related page,” proving the
    organization that posted the documents differs from Plaintiff.
    25
    Appellate Case: 21-1169    Document: 010110791250         Date Filed: 12/30/2022    Page: 26
    afford no confidentiality to a journal containing information purposefully made
    public, but it is quite another to afford no confidentiality to documents mistakenly
    disclosed and then made public after Plaintiff shared those documents with another
    organization to disseminate. Thus, Anderson does not apply.
    Plaintiff also relies on cases holding that an agency cannot tell a FOIA
    requester who it can share records with once the agency properly discloses the
    records. See Nat’l Archives & Recs. Admin. v. Favish, 
    541 U.S. 157
    , 174 (2004)
    (“[O]nce there is disclosure, the information belongs to the general public. There is
    no mechanism under FOIA for a protective order allowing only the requester to see
    whether the information bears out his theory, or for proscribing its general
    dissemination.”); Maricopa Audubon Soc’y v. U.S. Forest Serv., 
    108 F.3d 1082
    , 1088
    (9th Cir. 1997) (“FOIA does not permit selective disclosure of information only to
    certain parties . . . once the information is disclosed to Audubon, it must also be
    made available to all members of the public who request it.”). But for those cases to
    control, the agency must have properly divulged the documents. Here, Defendant
    accidentally turned over two documents without proper redactions that Plaintiff never
    had a right to possess under FOIA. So the issue is not one of who received them, but
    whether any member of the public had a right to receive them.
    At bottom, Plaintiff argues that the district court could not authorize Defendant
    to claw back mistakenly disclosed documents because another organization posted
    them online. But the government waives the ability to exempt a document under
    FOIA only after it has already released the same information to the public. See
    26
    Appellate Case: 21-1169    Document: 010110791250        Date Filed: 12/30/2022    Page: 27
    Herrick, 
    298 F.3d at 1193
    . Plaintiff does not claim that Defendant made the
    information public before the inadvertent disclosure occurred. Plus, none of the
    cases we relied on in Herrick involved inadvertent disclosures of exempt records.
    See 
    id.
     (citing Pub. Citizen v. Dep’t of State, 
    11 F.3d 198
    , 201 (D.C. Cir. 1993)
    (information previously disclosed through congressional testimony); Davis v. U.S.
    Dep’t of Just., 
    968 F.2d 1276
    , 1279 (D.C. Cir. 1992) (information previously
    disclosed through tapes played during a trial); Afshar v. Dep’t of State, 
    702 F.2d 1125
    , 1129–31 (D.C. Cir. 1983) (information not previously disclosed, but similar
    information that the government never acknowledged had allegedly been previously
    released to the public)). What is more, Plaintiff cites no authority barring courts
    from ordering the return or destruction of inadvertently disclosed records subject to
    FOIA exemptions. We agree with the district court that the public dissemination by a
    third party of inadvertently disclosed documents does not erase their exempt status
    and also affirm its claw-back order.
    AFFIRMED.
