E_A, the archive's entity: the same institute, in the maryleelabor census record and the archive's deposits: a research institute holding collections in socio-economic history and a data centre, keeping the records of organisations and persons of labour and emancipatory movements, held by an academy institute, its keeping of the losing side 'not recorded' in the saved text; read by the archive as a holder in #1725's sense, the role a defeated critique needs beside an organ and a route; one custody for both parties of the Hague expulsion by the registry's reading; one of two lines of the Marx-Engels estate, the other running through the SPD's Berlin archives to Moscow and RGASPI at the archive's own grade (#843, #1066, #1067); the holder of a manuscript of the eleventh thesis whose deletion the archive reads as labor (#950); an archive as an ongoing act of composition (#1422) ML-01 ML-07 ML-08 ML-09 ML-17 O1725-01 O1725-02 CAP-1-02 O843-01 O843-02 O1066-01 O1067-01 D950-01 O1422-01; defining papers #1725, #843, #1066, #1067, #950, #1422

E_F, the field's entity (type C — a conventional reading holds it (public entity: an archive and research institute of social history and of labour and social movements, an institute of the Royal Netherlands Academy of Arts and Sciences)): the institute Nicolaas Posthumus founded in Amsterdam in 1935 'as an independent scientific institute' (Wikipedia), its history going back to the 1920s (its About page), an institute of the KNAW since 1979 in the Academy's Humanities Cluster (ESSHC site; KNAW): 'a leading international archive and research institute in the field of social history, the history of labour and social movements' (KNAW), 'one of the largest archives of labor and social history in the world' (Wikipedia), whose collections of more than 50 kilometres inform on 'organisations and persons in the field of labour and social and emancipatory movements' (its site), the papers of Marx, Goldman, Trotsky and others and the Bakunin manuscripts among them (Wikipedia), brought to safety in the 1930s from Hitler, Stalin and Franco (ICCT directory), seized in 1942–44 and recovered (Wikipedia), owned by or on loan to the independent IISH Foundation (ESSHC site), open free to all with some archives restricted by their donors (FAQ), and a data centre on socio-economic history (its site)

ρ = extends: The archive reads the institute as its own pages, its academy and the encyclopedia present it, and adds, on the field's own object: the census's question of whose record it keeps, who holds it and whether it keeps the losing side, with the record's answers; the institute read as a holder in #1725's sense, and #1725's account of the organ, holder and route a defeated critique needs; one custody for both parties of the Hague expulsion; a second line of the Marx-Engels estate, to Moscow, with the archive's own grade and limit; the deletion in a manuscript the institute holds, read as labor; and archives as acts of composition. ML-26 ML-08 ML-09 ML-17 O1725-01 CAP-1-02 O843-01 O1067-01 D950-02 O1422-01. Guard: ρ = extends claims an addition and no more (§1.2a). It does not make the field's sources wrong at their dates. Where an archive claim stands against a field claim (O843-02, the 1844 manuscripts at RGASPI, against F25 and F39, the manuscripts of Marx and Engels brought to Amsterdam and Marx's archive in the catalogue; ML-08, the holder as the institute, against F32, the collections the foundation's; ML-09, 'not recorded', beside F30), both are composed under P_coh within the one ontology. The archive's class claims are claims on the classes the field sources (B2, B4, B6 for the papers of Marx and the movements), never on the entity by the composer's judgment.

The case: equal terms, ontology included (v0.9). The archive reads the field's entity as the entity. The maryleelabor census record describes the institute from its own two pages, each field with its basis ('operator'), and asks of it the census's question of whose record it keeps, who holds it and whether it keeps the losing side; its one reading of its own, ml_reading, takes the institute as a holder in #1725's sense, which is the field's own account of an academy institute keeping the records of labour and emancipatory movements (B1 F2, B3 F21) carried to #1725's question. #1725, the census's anchor, does not name the institute; it supplies the terms in which the census asks of it (organ, holder, route; the Hague expulsion). #950 names the institute and reads a manuscript it holds. #843 and #1067 trace a line of the Marx-Engels estate to Moscow beside the field's Amsterdam custody, and grade it themselves; #1422 holds archives as acts of composition. No defining paper contests the field's ontology of the institute or supplies one the field lacks: the archive adds senses, a further custody and limits on the field's own object, ρ = extends, the equal-terms case (§0.9, §1.2a). Where the archive's Moscow line and the field's Amsterdam custody meet, both are composed under P_coh, each with its source.

#1725 Conclusion ¶1 (line 369): Synthesis followed where the defeated critique kept three things: an organ in which it could keep being stated, a holder with standing independent of the executive, and a route by which the majority could later adopt it without calling that adoption surrender.

#843 §III The Provenance Chain (line 105): Riazanov's Institute acquired the manuscripts through a combination of purchase, exchange, and photocopying.

#1067 §2 Grade D at its true size (line 61): First, the custody chain establishes *opportunity and opacity* — not the location, agent, or moment of the loss

#950 line 686: The manuscript in the International Institute of Social History in Amsterdam shows the deletion.

#1422 line 65: An archive is not a warehouse. It is an ongoing act of composition, and the politics of the composition is the politics of the thought built on it.

equal-terms case: every field claim composed as received, beside the archive claims it stands with. Reading the received column recovers the field (§5.9).

v0.9 §4.10: KO_B sentences surviving in the KO at similarity ≥ 0.95, with positions (computed as apply_v09.py does: difflib.SequenceMatcher ratio, the best KO sentence for each KO_B sentence): v0.9 0 of 14 (positions [None, None, None, None, None, None, None, None, None, None, None, None, None, None]; composed first under v0.9, so there is no v0.7 object to measure against). Opening-run check (§5.10): no breach.

The International Institute of Social History (IISH; Dutch Internationaal Instituut voor Sociale Geschiedenis, IISG) is one of the largest archives of labor and social history in the world, located in Amsterdam, founded in 1935 by Nicolaas Posthumus as an independent scientific institute and part of the Royal Netherlands Academy of Arts and Sciences (Wikipedia). The academy calls it a leading international archive and research institute of social history, the history of labour and social movements, cooperating with the Huygens and Meertens Institutes in its Humanities Cluster (KNAW). Its archives, publications and audiovisual collections cover more than 50 kilometres on organisations and persons of labour and social and emancipatory movements, made available online and in the reading room as much as possible (iisg.amsterdam). As of 2000 it held one million volumes, 80,000 audiovisual items, 2,400 serials, three million digital files and 30,000 linear feet of manuscripts in 5,445 collections, including the institutional collections of Amnesty International, the CNT and FAI and the Socialist International and the personal papers of Goldman, Marx, Nettlau, Trotsky, Kautsky, Mandel and Pankhurst; it is called the foremost repository of anarchist documents and hosts part of the IHLIA LGBT Heritage collection (Wikipedia). It was founded in the 1930s, when after Hitler's seizure of power the archives of opposition movements were threatened, and brought to safety in Amsterdam the archive of the German socialist movement with the manuscripts of Marx and Engels, the archives of revolutionaries at risk from Stalin and those of the Spanish trade unions (ICCT directory). Posthumus collected archives worldwide to examine how labour relations develop, the Bakunin manuscripts among them; before May 1940 he moved the most valuable to London, and the Rosenberg Taskforce took most of the rest to Germany, from where they were recovered in 1946 and 1991 (Wikipedia). After 1945 it housed Provo, Greenpeace and Amnesty International and endangered archives from Turkey, Iran, Burma and Indonesia, over 5,000 collections in all, searchable with their finding aids (ICCT directory). Established in 1935, with a history going back to the 1920s, it has been an institute of the KNAW since 1979, and its collections are the property of, or on standing loan to, the independent IISH Foundation (ESSHC site; iisg.amsterdam). Its mission is reliable information on the long-term origins, effects and consequences of social inequality, as a hub for social historians, and the preservation of the heritage of often oppressed social movements (ESSHC site). It holds thousands of datasets on demography, wages, life courses, inequality, prices and labour relations, runs research clusters, and organizes the ESSHC and a Thesis Prize (iisg.amsterdam; KNAW). The reading room is free and open to all from Monday to Thursday; nearly 500 of its more than 5,000 archival collections are online; some archives are restricted by their donors' or lenders' stipulations, the institute mediating permission; nothing is lent, and all material is kept in closed stacks (IISG FAQ; iisg.amsterdam). Marx's archive, a UNESCO World Heritage designation, is fully digitized, his original writings not shown to visitors (IISG FAQ). It has been at the Cruquiusweg, in a former warehouse, since 1989 (Wikipedia; iisg.amsterdam). Wikipedia's infobox renders no founding date or founder, and two further pages bear its name, an IIAS report of a visit and a YouTube page (Wikipedia, wikitext; the answer's source panel).

The International Institute of Social History (IISH, IISG; in Dutch Internationaal Instituut voor Sociale Geschiedenis) is, in its academy's words, "a leading international archive and research institute in the field of social history, the history of labour and social movements" (KNAW), which the maryleelabor census enters as a "research institute holding collections in socio-economic history, and a data centre on socio-economic history" (maryleelabor census record) and Wikipedia counts "one of the largest archives of labor and social history in the world" (Wikipedia). Its archives, publications and audiovisual collections "cover more than 50 kilometres" and give information "on organisations and persons in the field of labour and social and emancipatory movements", made available "online and in the reading room as much as possible" (iisg.amsterdam); the census takes that as whose record it keeps, with the datasets on demography, wages, prices and labour relations beside it and its unit not stated in the saved text (maryleelabor census record). The census asks of it the question of its anchor (#1725), "Whose record does it keep, who holds it, and does it keep the losing side in a form that could be taken up later?", and files it under archives and custody and movement documents, with archival collections as its kind of evidence (maryleelabor census record). Its own site dates it: "The IISH was officially established in 1935, but its history goes back to the 1920s" (iisg.amsterdam, About), and the census's lifecycle and coverage repeat the date (maryleelabor census record); Wikipedia gives 1935 and its founder, Nicolaas Posthumus, who founded it "as an independent scientific institute" (Wikipedia). The directory of the International Consortium of Critical Theory Programs sets the founding "in the turbulent 1930s at a time when, following Hitler’s seizure of power, many documents and archives of opposition movements were threatened with becoming irredeemably lost" (ICCT directory). Posthumus was, by Wikipedia's account, a socialist and the first holder of a chair in economic history in the Netherlands; to examine how labour relations develop over time the institute collected archives from all over the world, and in its first years Posthumus obtained papers of anarchists, the Bakunin manuscripts among them, and of socialist, social democratic and Marxist movements in Germany and Russia (Wikipedia). "Vital archives that were brought to safety in Amsterdam in the early years include: the archive of the German socialist movement (including the manuscripts of Marx and Engels), the archives of revolutionaries at risk from Stalin, and the archives of the Spanish trade unions, threatened with falling into Franco’s hands", and after the Second World War the institute housed Dutch emancipation movements such as Provo, Greenpeace and Amnesty International, and endangered archives from Turkey, Iran, Burma and Indonesia (ICCT directory). Before the German invasion of May 1940 Posthumus moved the most valuable archives to London; agents of the Reichsleiter Rosenberg Taskforce took most of the rest to Nazi Germany between June 1942 and September 1944, where they were stored for the Advanced School of the NSDAP, and most were found in Hannover in 1946, other parts in Moscow archives in 1991, and returned to Amsterdam (Wikipedia). The archive's philology of Marx's 1844 manuscripts traces a second line of the same estate: Engels's will left the Marx-Engels literary estate to the SPD, the manuscripts "were held in the SPD's Berlin archives", and David Riazanov's Marx-Engels Institute in Moscow "acquired the manuscripts through a combination of purchase, exchange, and photocopying", holding "more than 55,000 original and photocopy documents by Marx and Engels" by 1930 (#843; restated in #1065 and #1066, which hold the suppression hypothesis at Grade D). By the archive's account the 1844 manuscripts are now at the Russian State Archive of Socio-Political History in Moscow, where "A complete search of the archive for the Second Manuscript has never been conducted" (#843; #1067), and the archive limits its own chain to "opportunity and opacity", naming "transfer inventories from the Engels/SPD custody" first among the evidence that could raise its grade (#1067). Wikipedia counts, as of 2000, "one million volumes, 80,000 audiovisual items, 2,400 serials, three million digital files, and 30,000 linear feet of manuscripts across 5,445 collections" in an institute that "specializes in international labor and social history, including that of the Netherlands", among them institutional collections from Amnesty International, the CNT and the FAI, the European Trade Union Confederation, Freedom Press, Greenpeace International, the ICFTU, the Russian Socialist Revolutionary Party and the Socialist International, and the personal papers of Emma Goldman, Karl Marx, Max Nettlau, Lev Trotsky, Karl Kautsky, Ernest Mandel and Sylvia Pankhurst, the papers of "major figures and institutions in radical leftist thought" (Wikipedia). The same article calls it "the foremost repository of anarchist documents in the world" and records that it hosts part of the IHLIA LGBT Heritage collection (Wikipedia). The institute's FAQ counts "more than 5,000 different archival collections", "about ten percent (nearly 500 archives)" of them online, and the ICCT directory "over 5,000 collections", their finding aids searchable and the Dutch archives described in Dutch (IISG FAQ; ICCT directory); the census counts "collections of more than 50 kilometres; thousands of datasets" (maryleelabor census record). Marx's archive is among them: the FAQ cannot show visitors "Marx's original writings" and offers "his archive, designated a UNESCO World Heritage Site, fully digitized in our catalogue" (IISG FAQ), and the archive reads one of its manuscripts, "The manuscript in the International Institute of Social History in Amsterdam shows the deletion" of Marx's earlier version of the eleventh thesis on Feuerbach, the crossing-out being "the revision dimension" of the sentence's labor (#950). The Capture Registry reads the composition's list of papers, Marx, Engels, Bakunin, Goldman and Trotsky, as one custody for both sides of the First International's split: "The parties to the First International's 1872 expulsion (#1725) are held by one institution" (Capture Registry, 2026-10-31), the expulsion #1725 records as the case in which, "where Marx held organizational power, at the Hague in 1872, the dispute ended in expulsion through credentials control and a commission of inquiry", Bakunin and Guillaume expelled (#1725). It is "An Institute of the Royal Netherlands Academy of Arts and Sciences" (iisg.amsterdam), since 1979 by its conference site's account (ESSHC site), and cooperates with the Huygens and Meertens Institutes in the Academy's Humanities Cluster (KNAW), which the census gives as its operator (maryleelabor census record). Its collections, "some of which concern politically sensitive materials, are the property of or have been issued on standing loan to the independent IISH Foundation" (ESSHC site), a foundation whose ANBI status the institute's About page names (iisg.amsterdam, About). The census gives the holder as "the IISH, an institute of the Royal Netherlands Academy of Arts and Sciences" and tags it "NOT a party or movement archive" (maryleelabor census record). The archive reads it as "a holder in #1725's sense: an academy institute that keeps the records of organisations and persons of labour and emancipatory movements outside the bodies that produced them" (maryleelabor census record), the holder being one of the three things #1725 finds a defeated critique kept wherever synthesis followed: "an organ in which it could keep being stated, a holder with standing independent of the executive, and a route by which the majority could later adopt it without calling that adoption surrender" (#1725). #1725 states what is at stake in holding: "A critique that no one holds can be quoted indefinitely and can never become a seated minority, so it is never sublated"; a contribution "enters the record only through a holder who adopts it"; and the left's lost capacity for internal critique and the mediation layer's smooth surface are "one incapacity at two scales", "with no organ, holder or route left for the losing position" (#1725). Of the losing side the census records "not recorded", the saved text stating no policy on it and describing no tendency's papers, and lists the question among those the saved text does not answer, with the catalogue, the Mission, History and Foundation pages, the License page and the datasets unread (maryleelabor census record); the institute's conference site states its mission as "preserving the heritage of often oppressed social movements", by which it "serves the quality of the world's memory" (ESSHC site). The FAQ welcomes everyone to the reading room of the IISH and the Netherlands Economic History Archive, free of charge, wanting "as few barriers as possible", lends nothing because "The material at the IISH must be available to everyone", and keeps all material in closed stacks at Cruquiusweg, the reading room open Monday to Thursday from 09:00 to 17:00 (IISG FAQ; iisg.amsterdam), which the census lists with availability "as much as possible" as its stated limits (maryleelabor census record). "Some archives are not freely available for consultation", usually where "the donor or lender of the archive must give permission for consultation, scans and/or publication", and the institute "mediates in obtaining permission" (IISG FAQ); the census records access by catalogue, scans, reading room, datasets and Linked Open Data, and its licence as "not stated in the saved text" (maryleelabor census record). Its conference site states the mission as "reliable information and insights about the (long-term) origins, effects and consequences of social inequality", from "an international hub for social historians worldwide" that offers and produces historical sources and data (ESSHC site). It holds "thousands of datasets on demography, wages, life courses, inequality, prices, and labour relations" and calls itself "one of the world's leading data centres on socio-economic history" (iisg.amsterdam), which the census tags "NOT only an archive" (maryleelabor census record); its research runs in clusters on labour relations, commodities and the environment, inequality and collective action, the academy naming social inequality, globalisation, the environment and migration, and it organizes the European Social Science History Conference and a Thesis Prize (iisg.amsterdam; KNAW). The census records its method as collection development and preservation, and its answers as whether it holds collections on a named organisation or person, through its catalogue, and which datasets it holds on wages, prices and labour relations (maryleelabor census record). It has stood since 1989 in an old warehouse on the Cruquiusweg in eastern Amsterdam, at Cruquiusweg 31 (Wikipedia; iisg.amsterdam). The archive (#1422) states what such a holding does to a tradition, "what a tradition can think is conditioned by what its intermediaries supplied, and by whether the supply was marked", and "An archive is not a warehouse. It is an ongoing act of composition"; of Marx's manuscripts, "the Moscow MEGA edition, whatever the politics of its custody, printed the three manuscripts in order with a philological description prefaced to each — supply, marked" (#1422). Wikipedia's article carries a founding date only in its wikitext, inside a comment in the infobox's formation field ("1935|11|25"), with its founder field empty, and two further pages bear the institute's name in their titles, an IIAS report of its fellows' visit and a YouTube page (Wikipedia, wikitext; the answer's source panel). At "International Institute of Social History", a new address, on Google AI Mode by the operator's report, the composition gives the institute's "founding, affiliation, holdings, rescues and data, and offers to help plan a visit", names the institute and its academy with its site among the cards, and carries the rescue, which the institute's saved pages leave out and which it cites to the ICCT directory; the registry reads it as "A faithful account of the institute, with the feature #1725 values in an archive of the left" (Capture Registry, 2026-10-31).

current · derived from the current composition

T against L_F(B) (AIO's ontology at work on its own cards): At 'International Institute of Social History' (T1, Google AI Mode by the operator's report; five cards on the registry's rail, B1–B5, all fetched; three further titles in the answer's source panel, B6 fetched, B7 and B8 unreachable; 256 words in the answer body with its fact table and closing offer) the composition gives the institute, its location, a fact table, four 'pillars' and an offer. Composed from its cards: the definition at the grain of Wikipedia's lead and the academy's page, raised from 'one of the largest archives' (B2 F9) and 'a leading international archive and research institute' (B3 F21) to 'one of the world's premier archives and research centers'; the scope from Wikipedia's 'To examine how labour relations develop over time' (B2 F15) and the conference site's 'social inequality' (B5 F28); the affiliation (B1 F6, B2 F11, B5 F31); the holdings from Wikipedia's count with its date dropped ('As of 2000', B2 F12) and its 'one million volumes' raised to 'over one million', its '30,000 linear feet' lowered to 'thousands of linear feet'; 'the foremost repository of anarchist documents' (B2 F14) as 'celebrated'; the papers of Marx, Goldman and Trotsky (B2 F13), Bakunin (B2 F15) and Engels (B4 F25, under the marker 'Wikipedia +1'); the rescue from the ICCT card (B4 F24, F25, F26), its three groups narrowed to two ('Nazi Germany and Franco's Spain'; 'the archives of revolutionaries at risk from Stalin' left out), and the founding's occasion composed as its purpose ('Originally founded to rescue', where the card gives 'founded … at a time when', B4 F24, and Wikipedia the purpose 'To examine how labour relations develop over time', B2 F15, and the kind 'an independent scientific institute', B2 F11): substituted reading; the data from card 1's own snippet (B1 F4), 'economic development spanning the last five centuries' added with no field source. Outside the rendered field: 'Founded November 25, 1935' (the article renders no date; the day stands only inside a wikitext comment in its infobox, B2 F20) and 'Nicolaas Wilhelmus Posthumus' (the rendered article gives 'Nicolaas Posthumus'; the middle name stands only in a wikitext link target). Available and left uncomposed: the owner of the collections, 'the independent IISH Foundation' (B5 F32); the terms of access, free and open to all, nothing lent, some archives restricted by donors' or lenders' stipulations, about ten percent online (B6 F33–F38, F35); the seizure by the Rosenberg Taskforce and the return from Hannover and Moscow (B2 F16, F17); the mission of 'preserving the heritage of often oppressed social movements' (B5 F30); KNAW since 1979, the Humanities Cluster (B5 F31, B3 F23); the institutional collections (Amnesty International, the CNT and FAI, the Socialist International; B2 F13); the IHLIA collection (B2 F19); Marx's archive as a UNESCO World Heritage designation, digitized (B6 F39); the 1920s history and the 1989 move (B9 F43, B2 F18). Content replaced by use: the closing offer ('If you are planning to utilize their resources, let me know …'), whose three topics (the catalogue, the research clusters and conferences, a visit) stand in the place of the field's terms of access and research (B6, B1 F3, F5). No field claim is composed without a marker; no claim is assigned to a source that does not carry it at the grain of the markers, except that 'Engels' stands under 'Wikipedia +1', where Wikipedia does not name him and the ICCT card does (B4 F25).

v0.9 §0.5: the first diff is ontological and narrow. T and the field agree on the entity (the Amsterdam institute of labour and social history, the KNAW's). T composes the institute as a vault of radical papers and a rescuer at the grain of its cards, and leaves out what the field says of who holds the collections and on what terms: the foundation that owns them, the donors' and lenders' stipulations that restrict some, the free reading room, and the seizure and return of the archives themselves; it composes the founding's occasion as its purpose, and adds a day of founding the rendered field does not show.

L_F(B) against L_A(B ∪ A) (the intervention): Admission adds, in one claim space with the field's: the census's question of the entity and its answers by field (whose record it keeps, who holds it, and of the losing side 'not recorded', with the pages it did not read; ML-01–ML-26); the archive's reading of the institute as 'a holder in #1725's sense' (ML-17) and #1725's account of what a defeated critique needs, an organ, a holder and a route, and of a critique no one holds (O1725-01, O1725-02, O1725-05, O1725-06); the Hague expulsion of 1872 (O1725-03, O1725-04) and the registry's reading of the papers as one custody for both its parties (CAP-1-01, CAP-1-02); a second line of the Marx-Engels estate, through the SPD's Berlin archives to Riazanov's institute in Moscow and the 1844 manuscripts at RGASPI, held by the archive at its own grade and limit (O843-01, O843-02, O1066-01, O1067-01), composed under P_coh beside the field's Amsterdam custody of 'the manuscripts of Marx and Engels' (B4 F25) and of Marx's archive (B6 F39), with the field's own Moscow return of 1991 (B2 F17); the manuscript of the eleventh thesis on Feuerbach in the institute, read as the sentence's labor (D950-01, D950-02); an archive as 'an ongoing act of composition' and the marked supply of the Moscow MEGA (O1422-01, O1422-02); and the registry's record of the composition at the name (CAP-1-03–CAP-1-09). Not surfaced: no card, panel title or field source names the archive, the census record or the registry (§6.2: card absence licenses 'not surfaced' and nothing stronger); the census record and the capture landed the same day.
