--- slug: how-many-words-did-shakespeare-know passed: 2026-10-14 by: the assay line (research/assay-line/cited-1014b/), Codex fixer directed by claude-assaying-boyle-1014; source record by Codex, checked by Codex and a Claude agent checked: 168 confirmed: 135 wrong: 33 unverifiable: 0 observed: 0 stale: 0 --- This was the directed repair pass for the layer read at a6541a95b3, using the 40 decisions in research/assay-line/cited-1014b/how-many-words-did-shakespeare-know/triage.json. The fixer independently re-read the evidence for each edit, recounted the committed corpus and reran the disputed estimator calculations. The additional CONFIRMED entries preserve the two checkers' source readings, deduplicated by N1 claim ID, with triage verdicts taking precedence and the limited wording adjustments identified below. Earlier snapshot citations remain dated to 67088387e0; retained confirmations are not a claim that the fixer independently reread every outside source. All 18 MINOR lines count toward wrong; 16 are deliberately left unchanged under the triage's Tier C rule. Quoted typography is normalized without changing the claim. Eight public correction lines cover the eight distinct WRONG errors; the two MINOR fixes have no separate public line. Repair review on 2026-10-14 keeps X16 open for an unannotated copy in another layer; this layer's source note and footer are already corrected. ## Claims - CONFIRMED | X1 [hypothetical-canon-size] [16] "another 36 plays and 150 sonnets" | [source](https://www.shakespeare.org.uk/explore-shakespeare/shakespedia/william-shakespeare/william-shakespeare-biography/); public/strata/how-many-words-did-shakespeare-know/index.html | REJECTED with evidence: the sentence begins Suppose we discovered and specifies an imagined equally large corpus, not a census. The rounded illustration stays. - WRONG | X2 [parametric-lp-bound] [31] "a parametric assumption about how a writer's rare words are distributed, plus a linear program" | [Efron 2021](https://efron.ckirby.su.domains/papers/2021EB-concepts-methods.pdf) | FIXED: Efron 2021 p. 10, equation 2.21, describes a nonparametric LP bound. The 1976 construction, pp. 444-445, retains sampling assumptions and a tolerance; no parametric rate distribution is required. Corrected the HTML and the verifier/estimator comments and their public mirrors. - MINOR | X3 [model-free-doubling] [37] "model-free" | [Efron & Thisted 1976](https://gwern.net/doc/statistics/order/capture/1976-efron.pdf) | NOT FIXED: nonparametric is more precise; 1976 p. 436 still assumes representative sampling. Listed MINOR under Tier C as directed, separate from the WRONG LP sentence. - WRONG | X4 [poem-new-words] [48] "the nine new words include admiration, besots, exiles, tormentor, twined" | [source](https://www.dbnl.org/tekst/_twe007198901_01/_twe007198901_01_0137.php); research/assay-line/cited-1014b/how-many-words-did-shakespeare-know/fixer-evidence.json | FIXED: DBNL stanza 7 reads admirations. Recount gives admiration=14, admirations=0 and twined=2 in this page's Gutenberg corpus. Removed the illustrative list; the modern corpus does not establish whether twined was new to the 1987 study's different concordance. - WRONG | X5 [poem-never-canon] [51] "the poem has never entered the canon" | [source](https://academic.oup.com/fmls/article-abstract/42/3/327/657303) | FIXED: the Oxford Academic review of the 2005 Complete Works, published in 2006, states that the poem was retained from the 1986 edition despite an authorship dispute. Inclusion is not proof or consensus. - MINOR | X6 [first-citation-count-origin] [54] "The number comes from counting the words" | [Dead Languages Society](https://www.deadlanguagesociety.com/p/how-many-words-did-shakespeare-invent) | NOT FIXED: Dead Language Society footnote 3 explains the popular 1,700 as a midpoint of 1,392 and 2,035. The page identifies the underlying OED exercise but omits that step. Listed MINOR under Tier C as directed. - WRONG | X7 [uniquely-searchable-shakespeare] [57] "uniquely searchable decades before anyone else's" | [source](https://play.google.com/store/books/details/John_Milton_A_Verbal_Index_to_Milton_s_Paradise_Lo?id=ZsJgAAAAcAAJ) | FIXED: the Google Books/Play catalogue dates A Verbal Index to Milton's Paradise Lost to 1741. Retained the supported benefit of Clarke's 1845 concordance and removed historical exclusivity. - WRONG | X8 [crystal-starting-count] [66] "trims the ~1,700 first-citations to roughly 1,392 plausible coinages" | [Crystal supplement](https://www.davidcrystal.com/Files/BooksAndArticles/-5221.pdf) | FIXED: Crystal's supplement, PDF pp. 13-14, section Page 161, totals 2,200 first-recorded words and senses. Its strongest three categories sum to 309+48+1,035=1,392. Replaced the false 1,700 starting tally and named both counting units. - MINOR | X9 [all-numbers-recomputed] [73] "every number here is recomputed, not quoted" | `git show 67088387e0:research/shakespeare-vocabulary/verify.mjs` | NOT FIXED: the verifier recomputes the local corpus and estimator, but quotes historical targets and does not calculate the LP bound or poem table. Listed MINOR checking-scope overclaim under Tier C as directed. - CONFIRMED | X10 [regenerate-every-figure] [79] "Re-run node verify.mjs to regenerate every figure." | `git show 67088387e0:research/shakespeare-vocabulary/verify.mjs` | REJECTED with evidence: this instruction belongs to the own-corpus bullet; verify.mjs computes those figures. The page explicitly says the repository is required, so failure of a standalone download does not refute it. - WRONG | X11 [eighth-term-tail-guarantee] [82] "already converged by the 8th term (so the unpublished tail can't move it)" | [Efron 2021](https://efron.ckirby.su.domains/papers/2021EB-concepts-methods.pdf); research/assay-line/cited-1014b/how-many-words-did-shakespeare-know/fixer-evidence.json | FIXED: Efron 2021 Table 3, p. 9, publishes counts through n_100, including n_13=242. Independent rerun: K8=11437.0742, K12=11434.4780 and K20=11421.2821.

Only the separate categorical limit on all inference was corrected under K4. - MINOR | X15 [zipf-no-information] [143] "it carries almost no linguistic information." | [Ferrer-i-Cancho & Elvevag 2010](https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0009411) | NOT FIXED: Ferrer-i-Cancho and Elvevag 2010 dispute the asserted fit and leave the linguistic significance open. Listed MINOR for the unqualified assessment, as directed; it is a separate sentence from the monkey-immunity guarantee. - WRONG | X16 [random-text-unseen-words] [145] "which no monkey could fake." | [Efron & Thisted 1976](https://gwern.net/doc/statistics/order/capture/1976-efron.pdf); research/assay-line/cited-1014b/how-many-words-did-shakespeare-know/fixer-evidence.json | PARTLY FIXED: 1976 p. 437 says these estimates use frequency counts, ignoring labels. Recreated seeded random-key control: mean predicted unseen strings 156.5980, observed 157.9050 over 200 pairs of 5,000-word samples. Removed the guarantee in the relates note and footer; the inference also applies to random strings. The preserved copy at public/strata/there-here/index.html:250 and research/lineage-edge-grammar/page.json:1 still makes the false guarantee without an adjacent correction. Those files belong to another layer and cannot be edited in this repair; a board note and correction annotation are pending. - WRONG | X17 [random-text-unseen-words] [146] "something a monkey can't fake" | [Efron & Thisted 1976](https://gwern.net/doc/statistics/order/capture/1976-efron.pdf); research/assay-line/cited-1014b/how-many-words-did-shakespeare-know/fixer-evidence.json | FIXED: 1976 p. 437 says these estimates use frequency counts, ignoring labels.

[one-more-canon-only] | https://gwern.net/doc/statistics/order/capture/1976-efron.pdf | FIXED: 1976 p. 442 gives an accelerated estimate at t=10; pp. 445-446 give bounds beyond t=1 and discuss rapidly growing uncertainty. Corrected the categorical limit in HTML, the scripted explanation, Markdown/dek and verifier comments; retained the authentic quotation about the raw series. - WRONG | K5 [parametric-lp-bound] To answer it at all, Efron and Thisted had to add a model: a parametric assumption about how a writer's rare words are distributed, plus a linear program to bound the answer from below. [parametric-and-lp] | https://efron.ckirby.su.domains/papers/2021EB-concepts-methods.pdf ; https://gwern.net/doc/statistics/order/capture/1976-efron.pdf | FIXED: Efron 2021 p. 10, equation 2.21, describes a nonparametric LP bound.

The 1976 paper p. 436 requires representative sampling and p. 445 changes the LP bound from 35,554 to 30,845 when c moves from 1 to 2. Nonparametric does not mean assumption-free. Kept the valid caveat; corrected the separate parametric claim. - CONFIRMED | K7 [lower-bound-model-dependence] Treat them with the caveat Efron himself insists on: they are a lower bound, and they ride on a modelling choice.

Checker record: research/assay-line/cited-1014b/how-many-words-did-shakespeare-know/N2-claude.md. ## Findings - [fixed] X2 [parametric-lp-bound]: FIXED: Efron 2021 p. 10, equation 2.21, describes a nonparametric LP bound. The 1976 construction, pp. 444-445, retains sampling assumptions and a tolerance; no parametric rate distribution is required. Corrected the HTML and the verifier/estimator comments and their public mirrors. Triage rationale: I fetched and reread Efron 2021, p. 10, equation (2.21): "nonparametric lower bound" (https://efron.ckirby.su.domains/papers/2021EB-concepts-methods.pdf). The LP bound does not require the asserted parametric distribution of rare-word rates. Correct the authored explanation and its copies, with a dated Corrected line shared with K5. Preserve the separate, valid caveat that the bound depends on sampling assumptions. - [declined] X3 [model-free-doubling]: NOT FIXED: nonparametric is more precise; 1976 p. 436 still assumes representative sampling. Listed MINOR under Tier C as directed, separate from the WRONG LP sentence. Triage rationale: I reread Efron and Thisted 1976, section 2, p. 436. The estimate assumes representative sampling even without specifying a parametric rate distribution. Model-free is loose shorthand for nonparametric. Tier C: list this MINOR precision issue. Its sentence at index.html lines 217-218 is separate from the WRONG parametric-and-LP sentence at lines 207-209. - [fixed] X4 [poem-new-words]: FIXED: DBNL stanza 7 reads admirations. Recount gives admiration=14, admirations=0 and twined=2 in this page's Gutenberg corpus. Removed the illustrative list; the modern corpus does not establish whether twined was new to the 1987 study's different concordance. Triage rationale: I fetched the DBNL poem and reread English stanza 7: "All her parts merit high admirations." (https://www.dbnl.org/tekst/_twe007198901_01/_twe007198901_01_0137.php). Independently counting the repository pg100.txt at 67088387e0 with its tokenizer gives admiration=14 and admirations=0. Restore the source form admirations in the illustrative list. Share the correction and dated Corrected line with K9; preserve the poem wording. - [fixed] X5 [poem-never-canon]: FIXED: the Oxford Academic review of the 2005 Complete Works, published in 2006, states that the poem was retained from the 1986 edition despite an authorship dispute. Inclusion is not proof or consensus. Triage rationale: I reread the Oxford Academic extract of the 2006 review, Forum for Modern Language Studies 42(3), p. 327: "retains its place among Various Poems" (https://academic.oup.com/fmls/article-abstract/42/3/327/657303). The review identifies inclusion in the 1986 Oxford Complete Works and retention in 2005. Thus never entered the canon is too absolute, even though Efron repeats it. Say Oxford included the poem while authorship remains disputed; add a dated Corrected line. Do not turn inclusion into consensus or proof. - [declined] X6 [first-citation-count-origin]: NOT FIXED: Dead Language Society footnote 3 explains the popular 1,700 as a midpoint of 1,392 and 2,035. The page identifies the underlying OED exercise but omits that step. Listed MINOR under Tier C as directed. Triage rationale: I reread the Dead Language Society article, footnote 3 (https://www.deadlanguagesociety.com/p/how-many-words-did-shakespeare-invent): it derives 1,700 by "splitting the difference between 1,392 and 2,035". The page broadly identifies the correct underlying OED counting exercise, but omits how the popular rounded number was formed. This is MINOR precision. Tier C: list; this sentence is separate from the false Crystal starting tally in X8/K10. - [fixed] X7 [uniquely-searchable-shakespeare]: FIXED: the Google Books/Play catalogue dates A Verbal Index to Milton's Paradise Lost to 1741. Retained the supported benefit of Clarke's 1845 concordance and removed historical exclusivity. Triage rationale: I reread the Google Books/Play catalogue result for "A Verbal Index to Milton's Paradise Lost", which dates that book to 1741 (https://play.google.com/store/books/details/John_Milton_A_Verbal_Index_to_Milton_s_Paradise_Lo?id=ZsJgAAAAcAAJ). That predates Clarke's 1845 concordance by 104 years and refutes the unrestricted anyone else comparison. Remove the historical exclusivity, retaining only a supported account of Shakespeare's indexing advantage; add a dated Corrected line. - [fixed] X8 [crystal-starting-count]: FIXED: Crystal's supplement, PDF pp. 13-14, section Page 161, totals 2,200 first-recorded words and senses. Its strongest three categories sum to 309+48+1,035=1,392. Replaced the false 1,700 starting tally and named both counting units. Triage rationale: Re-levelled from MINOR to WRONG after rereading Crystal's supplement, PDF p. 14, the section labelled Page 161: "If all words are accepted, the total is 2200." (https://www.davidcrystal.com/Files/BooksAndArticles/-5221.pdf). Its first three categories total 1,392 and include word senses. This is a false account of Crystal's starting tally, not rounding: 1,700 is the separate popular estimate, not his input count. Correct the attribution and counting units, sharing one dated Corrected line with K10. - [declined] X9 [all-numbers-recomputed]: NOT FIXED: the verifier recomputes the local corpus and estimator, but quotes historical targets and does not calculate the LP bound or poem table. Listed MINOR checking-scope overclaim under Tier C as directed. Triage rationale: I reread verify.mjs at 67088387e0. Lines 129-130 quote the historical totals and target; there is no LP-bound or poem-table calculation. The heading overstates the scope of the page's checking. The task explicitly classifies this type of overclaim as MINOR. Tier C: list, sharing the label with K11. This heading is not a sentence already being fixed for WRONG. - [fixed] X11 [eighth-term-tail-guarantee]: FIXED: Efron 2021 Table 3, p. 9, publishes counts through n_100, including n_13=242. Independent rerun: K8=11437.0742, K12=11434.4780 and K20=11421.2821. Removed the convergence/tail guarantee in HTML, Markdown, data notes and verifier; retained the approximate historical reproduction and added a check of the later terms. Triage rationale: I reread Efron 2021, p. 9 Table 3, including n13="242", and verify.mjs lines 98-100 at 67088387e0. The check tests only K=8,10,11,12. With the published spectrum and the repository estimator I obtain K8=11437.0742, K12=11434.4780, K20=11421.2821. Later terms change the result; that short plateau does not guarantee convergence or an immovable tail. Correct the guarantee everywhere, sharing a dated Corrected line with X13/X19/K21. The approximate historical reproduction remains valid. - [fixed] X12 [default-doubling-readout]: FIXED, MINOR: the default corpus gives 7643.2168; the E&T toggle gives 11434.4780. Qualified the Markdown sentence already being edited for X13; no separate public correction line. Triage rationale: I reread the page script and reproduced 7643.2168 for the default corpus and 11434.4780 for the E&T toggle at t=1. The missing toggle qualification is MINOR. Fix it under the Tier C same-sentence exception: the markdown sentence spanning lines 24-29 also contains the WRONG convergence claim X13. Name which corpus gives each estimate; this MINOR adjustment needs no separate Corrected line. - [fixed] X13 [eighth-term-tail-guarantee]: FIXED: Efron 2021 Table 3, p. 9, publishes counts through n_100, including n_13=242. Independent rerun: K8=11437.0742, K12=11434.4780 and K20=11421.2821. Removed the convergence/tail guarantee in HTML, Markdown, data notes and verifier; retained the approximate historical reproduction and added a check of the later terms. Triage rationale: I reread Efron 2021, p. 9 Table 3, which publishes n13="242", and the markdown sentence ending "already converged by the 8th term" at 67088387e0. My run of the repository estimator on that table gives K8=11437.0742, K12=11434.4780 and K20=11421.2821. Correct this duplicate guarantee with X11/X19/K21 and their shared dated Corrected line; do not label the approximate 11,430 reproduction itself false. - [declined] X14 [forced-divergence-warning]: NOT FIXED: the warning uses t>1.28. At t=1.29 the finite outputs are 9508.8952 and 13978.5384; at 1.30 they are 9606.5697 and 14060.4019. The displayed warning and demonstration overclaim remain listed MINOR as directed. Only the separate categorical limit on all inference was corrected under K4. Triage rationale: I reread index.html lines 524-528: the warning is triggered by "if(t>1.28 || d>d1*1.6)". My calculations at t=1.29 give 9508.8952 and 13978.5384 for the two corpora, below the ratio trigger. The message overstates what the in-page check has detected, using divergence for a chosen cutoff. Retain MINOR as an overclaim of checking; Tier C: list with K3/K17. Do not change the adjacent genuine Efron quotation. - [declined] X15 [zipf-no-information]: NOT FIXED: Ferrer-i-Cancho and Elvevag 2010 dispute the asserted fit and leave the linguistic significance open. Listed MINOR for the unqualified assessment, as directed; it is a separate sentence from the monkey-immunity guarantee. Triage rationale: Rule 4: the checker and the source-record abstract establish that the cited paper contests the inference from a Zipf-like curve to negligible linguistic information. Keep MINOR for the loose, unqualified assessment; Tier C: list with K18. In the relates note this is a different sentence from the WRONG monkey guarantee X16, so the same-sentence exception does not apply. - [open note:9e59b4] X16 [random-text-unseen-words]: PARTLY FIXED: 1976 p. 437 says these estimates use frequency counts, ignoring labels. Recreated seeded random-key control: mean predicted unseen strings 156.5980, observed 157.9050 over 200 pairs of 5,000-word samples. Removed the guarantee in the relates note and footer; the inference also applies to random strings. The preserved copy at public/strata/there-here/index.html:250 and research/lineage-edge-grammar/page.json:1 still makes the false guarantee without an adjacent correction. Those files belong to another layer and cannot be edited in this repair; a board note and correction annotation are pending. Triage rationale: I reread Efron and Thisted 1976, section 2, p. 436: "Poisson process" (https://gwern.net/doc/statistics/order/capture/1976-efron.pdf), and estimator.mjs at 67088387e0, which consumes only frequency counts. My independent random-string control, 200 pairs of 5,000 words, gives 156.598 predicted unseen types versus 157.905 observed. Each word has equiprobable a/b letters and continuation probability 0.6; the seeded LCG starts at 7241. This inference also works on random text. Remove the claimed immunity, sharing a dated Corrected line with X17. - [fixed] X17 [random-text-unseen-words]: FIXED: 1976 p. 437 says these estimates use frequency counts, ignoring labels. Recreated seeded random-key control: mean predicted unseen strings 156.5980, observed 157.9050 over 200 pairs of 5,000-word samples. Removed the guarantee in the relates note and footer; the inference also applies to random strings. Triage rationale: I reread Efron and Thisted 1976, section 2, p. 436: "Poisson process" (https://gwern.net/doc/statistics/order/capture/1976-efron.pdf), and the page's count-only estimator at index.html lines 418-431. The independent random-string control described in X16 predicts unseen strings accurately: 156.598 predicted, 157.905 observed. Counting the same multiplicities as ranks or as a spectrum adds no test of linguistic meaning. Correct this footer copy of the guarantee and share X16's dated Corrected line. - [declined] X18 [benford-fraud-certainty]: NOT FIXED: the linked Benford layer calls this a filter and rejects treating a violation as proof of fraud. Listed MINOR for loose wording under Tier C as directed. Triage rationale: I reread the linked Benford layer's markdown at 67088387e0, lines 40-42: it describes a filter and rejects treating a violation as proof of fraud. Identifies is loose shorthand for flagging suspicious data under applicable assumptions. Retain MINOR; Tier C: list. This sentence contains no WRONG item being fixed. - [fixed] X19 [eighth-term-tail-guarantee]: FIXED: Efron 2021 Table 3, p. 9, publishes counts through n_100, including n_13=242. Independent rerun: K8=11437.0742, K12=11434.4780 and K20=11421.2821. Removed the convergence/tail guarantee in HTML, Markdown, data notes and verifier; retained the approximate historical reproduction and added a check of the later terms. Triage rationale: I reread Efron 2021, p. 9 Table 3 (https://efron.ckirby.su.domains/papers/2021EB-concepts-methods.pdf): n13 is "242", followed by counts through n100. These terms were published, merely omitted from the page's 12-term input. My estimator run also changes from 11434.4780 at K12 to 11421.2821 at K20. Correct the unpublished and immovable-tail claims with X11/X13/K21, sharing one dated Corrected line. - [declined] K1 [hapax-corpus-scope]: NOT FIXED: independent recount gives 10164/26909=37.771749%, supporting 37.8% or about 38% for this corpus. The historical 14376/31534 uses different inputs. Listed MINOR only for the omitted local qualifier, as directed. Triage rationale: I reread the data and independently reproduced N=968242, V=26909 and n1=10164 from the repository corpus at 67088387e0. Their ratio is 37.7717%, so the displayed 37.8% is correct for this tokenizer. The 31,534-type historical concordance is explicitly distinguished later on the page. Retain MINOR only for the missing local corpus qualifier; Tier C: list. Do not replace the percentage with the other corpus's 45.6%. - [declined] K2 [hapax-corpus-scope]: NOT FIXED: independent recount gives 10164/26909=37.771749%, supporting 37.8% or about 38% for this corpus. The historical 14376/31534 uses different inputs. Listed MINOR only for the omitted local qualifier, as directed. Triage rationale: My independent corpus recount gives 10164/26909=37.7717%, supporting nearly two in five. I also reread the surrounding lowercase-count instructions and the later explanation of the two corpora. Retain MINOR only for wording that could more explicitly name this corpus; Tier C: list with K1/K19. The note does not justify changing a correct local fraction to the historical concordance's fraction. - [declined] K3 [forced-divergence-warning]: NOT FIXED: the warning uses t>1.28. At t=1.29 the finite outputs are 9508.8952 and 13978.5384; at 1.30 they are 9606.5697 and 14060.4019. The displayed warning and demonstration overclaim remain listed MINOR as directed. Only the separate categorical limit on all inference was corrected under K4. Triage rationale: I reread index.html lines 177 and 524-528 and recalculated its estimator: at the slider maximum t=1.30 the outputs are 9606.5697 and 14060.4019, respectively about 1.26 and 1.23 times their t=1 values. The warning is the fixed t>1.28 cutoff. Treat the claimed visible explosion as a MINOR overstatement of the demonstration; Tier C: list with X14/K17. This prose is a separate sentence from K4. Preserve Efron's genuine quotation about the raw series. - [fixed] K4 [doubling-only-limit]: FIXED: 1976 p. 442 gives an accelerated estimate at t=10; pp. 445-446 give bounds beyond t=1 and discuss rapidly growing uncertainty. Corrected the categorical limit in HTML, the scripted explanation, Markdown/dek and verifier comments; retained the authentic quotation about the raw series. Triage rationale: I fetched and reread Efron and Thisted 1976, pp. 442, 445-446 (https://gwern.net/doc/statistics/order/capture/1976-efron.pdf). Conclusion (ii) places the information limit at "t larger than 10"; Table 7 gives nonparametric bounds at t=3,5,10,20. The raw series's limit is not a limit on all information in the counts. Correct the categorical no-further claim and its copies, with a dated Corrected line. Explain that accelerated estimates reach further with growing uncertainty; preserve the authentic quotation about raw-series divergence. - [fixed] K5 [parametric-lp-bound]: FIXED: Efron 2021 p. 10, equation 2.21, describes a nonparametric LP bound. The 1976 construction, pp. 444-445, retains sampling assumptions and a tolerance; no parametric rate distribution is required. Corrected the HTML and the verifier/estimator comments and their public mirrors. Triage rationale: I reread Efron 2021, p. 10, equation (2.21): "nonparametric lower bound" (https://efron.ckirby.su.domains/papers/2021EB-concepts-methods.pdf), and the 1976 LP construction on pp. 444-445. A parametric rare-word distribution is not required for this bound. Fix this duplicate of X2, sharing its dated Corrected line. Correct parametric, while retaining valid cautions about sampling assumptions and the uncertainty tolerance. - [declined] K8 [past-doubling-confidence]: NOT FIXED: 1976 pp. 442 and 446 extend the estimates beyond a doubling with rapidly increasing uncertainty. The confidence judgment is loose caution, separate from K4's categorical impossibility claim. Listed MINOR under Tier C as directed. Triage rationale: I reread Efron and Thisted 1976, pp. 442 and 446: estimates extend beyond t=1 with rapidly growing uncertainty. The sweeping confidence judgment is loose caution, rather than a further precise impossibility theorem. Retain MINOR and list at Tier C. It is a separate sentence at index.html lines 218-219, not the categorical WRONG sentence in K4. - [fixed] K9 [poem-new-words]: FIXED: DBNL stanza 7 reads admirations. Recount gives admiration=14, admirations=0 and twined=2 in this page's Gutenberg corpus. Removed the illustrative list; the modern corpus does not establish whether twined was new to the 1987 study's different concordance. Triage rationale: I reread the DBNL English poem, stanza 7, including "high admirations", and independently counted the repository corpus: admiration=14, admirations=0, twined=2. The corpus includes "Were twined together" in The Two Noble Kinsmen. Restore the source form admirations in the illustrative list, sharing X4's dated Corrected line. The modern corpus alone cannot establish whether twined was new relative to the 1987 study's different concordance; do not assert that subfinding as settled without the study's list. Keep only verified examples or omit the list. - [fixed] K10 [crystal-starting-count]: FIXED: Crystal's supplement, PDF pp. 13-14, section Page 161, totals 2,200 first-recorded words and senses. Its strongest three categories sum to 309+48+1,035=1,392. Replaced the false 1,700 starting tally and named both counting units. Triage rationale: Re-levelled from MINOR to WRONG after rereading Crystal's supplement, PDF p. 14, section Page 161: "the total is 2200" (https://www.davidcrystal.com/Files/BooksAndArticles/-5221.pdf). The first three categories give 1,392 strong candidates, counting senses as well as words. The page falsely makes the popular 1,700 estimate Crystal's starting sample. Correct that specific attribution, sharing X8's dated Corrected line. - [declined] K11 [all-numbers-recomputed]: NOT FIXED: the verifier recomputes the local corpus and estimator, but quotes historical targets and does not calculate the LP bound or poem table. Listed MINOR checking-scope overclaim under Tier C as directed. Triage rationale: I reread the whole verifier at 67088387e0: it recalculates the local corpus and estimator results, quotes the historical targets, and contains no LP or poem calculation. This is the same checking-scope overclaim as X9. The task explicitly assigns it MINOR; Tier C: list, since its heading is separate from the WRONG convergence sentence. - [declined] K13 [publication-name]: NOT FIXED: the source masthead is Dead Language Society, singular Language. The 57/117 figure is supported. Listed MINOR bibliographic slip under Tier C as directed. Triage rationale: Rule 4: accept the checker's masthead correction from Dead Languages Society to Dead Language Society as a MINOR bibliographic name slip. Tier C: list. The 57/117 figure is confirmed, and this citation sentence is not already being fixed for a WRONG item. - [fixed] K15 [default-doubling-readout]: FIXED, MINOR: the default corpus gives 7643.2168; the E&T toggle gives 11434.4780. Qualified the Markdown sentence already being edited for X13; no separate public correction line. Triage rationale: I reread the markdown and browser estimator and reproduced 7643.2168 for the default corpus and 11434.4780 for E&T at t=1. As in X12, retain MINOR but fix under the same-sentence exception: this clause belongs to the markdown sentence also being corrected for WRONG X13. Identify the default and historical toggle values, with no separate Corrected line for the MINOR clarification. - [declined] K17 [forced-divergence-warning]: NOT FIXED: the warning uses t>1.28. At t=1.29 the finite outputs are 9508.8952 and 13978.5384; at 1.30 they are 9606.5697 and 14060.4019. The displayed warning and demonstration overclaim remain listed MINOR as directed. Only the separate categorical limit on all inference was corrected under K4. Triage rationale: I reread index.html lines 524-528. The code uses a fixed t>1.28 trigger; my t=1.29 values are 9508.8952 and 13978.5384. As in X14, the message overstates what the in-page check detected. Retain MINOR for checking-scope precision and list at Tier C, sharing the label with X14/K3. - [declined] K18 [zipf-no-information]: NOT FIXED: Ferrer-i-Cancho and Elvevag 2010 dispute the asserted fit and leave the linguistic significance open. Listed MINOR for the unqualified assessment, as directed; it is a separate sentence from the monkey-immunity guarantee. Triage rationale: Rule 4: the supplied note and source-record conclusion show that the cited paper contests this unqualified information claim. Retain MINOR for the loose assessment and list at Tier C, sharing X15's label. This is a separate sentence from the WRONG monkey guarantee X16, so correcting that guarantee does not trigger the same-sentence exception here. - [declined] K19 [hapax-corpus-scope]: NOT FIXED: independent recount gives 10164/26909=37.771749%, supporting 37.8% or about 38% for this corpus. The historical 14376/31534 uses different inputs. Listed MINOR only for the omitted local qualifier, as directed. Triage rationale: I independently recounted the repository corpus and reread the relates note: 10164/26909=37.7717%, correctly rounded to about 38%. The historical 14376/31534 count uses different inputs. Retain MINOR for the missing corpus qualifier; Tier C: list with K1/K2. Do not replace the correct local percentage with 45.6%. - [declined] K20 [reversed-nearby-direction]: NOT FIXED: the species layer's relates note and this page's Nearby box use identical here/there wording from the species page's perspective. Listed MINOR context slip under Tier C as directed; shared generation remains outside scope. Triage rationale: I reread the species layer's relates note at 67088387e0, line 18, and its copy in this page's Nearby box at index.html line 366. Here and there are copied from the species page's perspective, making the local direction confusing. This is a MINOR context/metadata wording slip. Tier C: list; it is separate from every WRONG sentence in this layer. - [fixed] K21 [eighth-term-tail-guarantee]: FIXED: Efron 2021 Table 3, p. 9, publishes counts through n_100, including n_13=242. Independent rerun: K8=11437.0742, K12=11434.4780 and K20=11421.2821. Removed the convergence/tail guarantee in HTML, Markdown, data notes and verifier; retained the approximate historical reproduction and added a check of the later terms. Triage rationale: Re-levelled from MINOR to WRONG after rereading Efron 2021, p. 9 Table 3: n13="242" and the remaining counts through n100 are printed (https://efron.ckirby.su.domains/papers/2021EB-concepts-methods.pdf). Unpublished is a false statement about the source, and my K12-to-K20 calculation changes the estimate from 11434.4780 to 11421.2821. The small relative change preserves the approximate reproduction but does not make either absolute claim true. Fix with X11/X13/X19 under one error label and dated Corrected line.
