Chapter 13. Nodes: How Differences Are Preserved, Given Definite Form, Extracted, and Passed On
Nodes include more than medical records, records of wedding and funeral exchanges, and archives. Bodies, language, genealogies, school disciplinary sanctions, platform accounts, local reputation, religious rituals, work-injury records, proof of residence, and kinship terms can all perform relay functions through which differences are preserved, certified, extracted, and passed on. This does not mean abstract dots on a network diagram, nor does it mean subsuming every phenomenon under some unified organization. If a person, institution, record, object, bodily trace, or relational position allows a difference to remain in a certain form and gives it a chance to be raised, identified, recognized, or passed on later, it may perform the function of a node within concrete relations.
I. Differences Do Not Preserve Themselves
That some differences have not entered into consequences at present does not mean they have disappeared. A worker has endured a bout of pain after a lower-back injury; someone has been absent from a wedding or funeral; an exchange between relatives has not been clearly explained. If these matters can still be raised later, saying only that "someone remembers" cannot explain this. Memory is only one form of preservation; bodily traces, medical records, receipts, past relations, and local reputation also leave different kinds of evidence. For a difference to exert an effect again in the future, it must first be preserved at some node.
But being preserved does not mean having already taken effect. Bodily pain can remain in the person's sensations, medical personnel can enter diagnoses and expenses into medical records, and relatives may remember an exchange at a wedding or funeral. Whether these differences can later enter judgments concerning borrowing money, leave requests, compensation, care, or courtship and marriage still depends on who raises them, who recognizes them, and the relational conditions at the time.
Preservation begins when specific people and procedures leave certain experiences, materials, or traces where they can be accessed again later, rather than depositing them in a static warehouse. If preserved differences are to enter later relations, someone must also continue to keep and interpret them, or bring them up when needed. Without these concrete relational processes, traces may exist yet still be unable to enter later judgments about eligibility, responsibilities, or mutual aid.
Different forms of preservation lead to different ways of raising differences later; how differences are preserved also affects what can be asked about them afterward. Bodily traces can remind a person of continuing pain without necessarily explaining how the injury occurred. A diagnostic certificate can explain a particular examination and judgment without necessarily covering care, interrupted income, and pressure from relatives. Relatives' memories can retain everyday exchanges, yet their emphases may vary with the narrator. Preservation therefore comprises a series of actions through which experiences, borne by different carriers, acquire conditions under which they can still be accessed later.
II. What Is a Node?
A node is a social relay position at which differentiating units can be preserved, given definite form, and filtered, their extraction can be authorized, and they can be passed on.
A node is first of all a social relay position, not the equivalent of an actor with clear boundaries and a unified will. The node granularity used in an analysis must be determined by the research question, actual acts of handling, differences in authority, and the need to trace responsibility. If the question is simply whether material can move from a school into another educational procedure, the school can provisionally be treated as a broadly defined node. If the question turns to who refuses the supplementation of materials, who can correct records, or who has authority to certify them, the analysis must break the node down into specific staff, rules, materials, and procedural positions.
Readers must also be able to check the actual choice of node granularity against the materials. Analysts should explain why they initially treat a particular institution as a broadly defined node, and which question of causation or responsibility leads them to break it down into personnel, rules, materials, authority, and procedures. If different ways of breaking it down lead to different judgments about consequences, the coarser node cannot be treated as the sole natural unit. Differences between levels should be retained, and the reasons for stopping further subdivision explained.
Nor can nodes be subdivided without limit. If an internal division of labor does not change how materials are extracted, passed on, judged, or connected to consequences, and does not affect authority or responsibility, further subdivision may add no explanatory power. Conversely, whenever different positions within the same institution have different authority over information, capacities for review, scopes of implementation, or responsibilities for correction, merging them into a single point will occlude causal linkage. Where subdivision stops must be determined by actual differences within the event, not by organizational names or the analyst's preferences.
People can perform node functions within relations. Relatives remember who borrowed money without repaying it; teachers record disciplinary sanctions or comments under school rules; village elders preserve past relations through wedding and funeral exchanges. Memory, standing, rules, and relational positions together enable differences to remain; individuals do not act out of nothing. Families, schools, hospitals, workplaces, courts, local police stations, neighborhoods, villages, and clans can likewise become nodes. These are not entities of the same kind: some handle materials through formal procedures, some preserve relations through long-term exchanges, and some accommodate several practices at once. Calling them all nodes means that they can allow differences to remain within relations, be identified, and possibly proceed into consequences, while specific staff within institutions handle materials and relations according to their responsibilities.
IOUs, contracts, records of wedding and funeral exchanges, household registration booklets, medical records, disciplinary notices, award certificates, chat logs, genealogies, stone inscriptions, and land deeds can likewise carry node functions. Documents, databases, accounts, and objects allow materials to be preserved, formatted, and retrieved later, but they are not acting subjects that can judge, authorize, refuse, or bear responsibility on their own. They carry differences already written down, registered, kept, or repeatedly used by people, and provide a form when someone retrieves them through the relevant authority or relations. Where causation and responsibility are involved, analysis must still identify who creates the records, who sets or enforces the rules, who has authority to access information, and who passes it on and handles it. Only by using the concept of the node in this way can analysis retain the organizational dimension at a general level without mistaking an organization, database, or document for a unified acting subject.
The relational field determines which differences are currently extracted, assigned weight, and connected; nodes concern the forms in which these differences are preserved, who may raise them under what authority or relations, and whether they can be passed on. The two must not be conflated. Bodies can retain injury, pain, and limitations on action; language can maintain differences through repeated forms of address; records and objects can carry relations already written into them. Yet when these carriers are seen, how they are interpreted, and whether they suffice to connect to consequences must still be traced back to the people, rules, and relations through which they are used. People can remember, raise matters, and interpret; documents and objects only carry traces already inscribed in them.
Thus, treating the node as a relay position does not merge people, institutions, language, and objects into one kind of actor; it serves to trace how differences are relayed. The name of a node merely marks a relay position that needs to be investigated. It cannot replace a concrete account of recorders, custodians, procedures, materials, and participants in relations. Only by separating these elements can we avoid mistaking functional shorthand for action by the node itself.
III. What Nodes Preserve Is Not Materials, but Conditions for Consequences
A medical record lists a name, a medical condition, examinations, medication, and expenses. Viewed only on paper, it looks like a piece of material; in leave requests, reimbursement, determinations of work-related injury, family care, and the allocation of expenses, however, people raise the bodily differences it contains as grounds for judgment. What it leaves is a condition that may later enter judgments within relations, rather than the sheet of paper itself. Records of wedding and funeral exchanges work in the same way. The names and amounts are more than sums of money: they may also allow people to ask later who came, who did not, who gave more, who gave less, and who should give a gift in return. The record reaches no conclusion on anyone's behalf, but provides a form through which specific participants in relations can interpret past exchanges again.
Household registration, residence permits, social insurance records, and rental registration turn part of the facts of lived experience into materials available for judgments of eligibility. An IOU, in turn, fixes part of a debt relation as evidence that relatives, mediators, or court personnel can examine. The consequences to which different forms of preservation can connect are not the same. What nodes preserve is differentiating units that can change future judgments within relations, not static materials.
Preservation does not guarantee that something will exert an effect again in the future. The material may not be raised at all; once raised, it may not be recognized; or it may be effective only within a particular relation. Preserving a difference merely leaves conditions for its possible entry into later judgments; it does not predetermine the result. The conditions retained through preservation may also weaken, be occluded, or fail to connect to a procedure because the material is incomplete. Whether the difference can continue to exert an effect depends on whether the later relational field needs it and whether the people concerned can raise and recognize it. To judge whether material performs a node function, one cannot ask only whether it exists; one must also ask who created it, where it is kept, who can access it, and in what relations it will be invoked. The same medical record, IOU, or other record may remain silent in one relational field and become an important basis for judgment in another.
Conditions for consequences are not consequences themselves. They are only a traceable basis on which later judgments may become possible. The same experience may also leave bodily traces, formal records, and memories within relations at the same time. These cannot replace one another, but may supplement one another on different occasions. Those who later grant recognition must still judge according to the materials, authority, and relations at that time.
IV. Giving Definite Form and Filtering: Reshaping the Forms of Recognition
Preservation never transfers reality unchanged into a record. When a worker says their lower back hurts, this is first a bodily sensation: when it began, where it hurts, whether an old injury has flared up, and what goods they have carried. These sensations do not automatically become social materials. Through consultation, examination, diagnosis, medication, and billing procedures, medical personnel turn part of them into entries in medical records, examination results, diagnostic labels, treatment records, and expense receipts.
This handling gives pain a form that can be retrieved later. Workplace staff, insurance personnel, staff determining work-related injury, court personnel, or family members may raise different questions on this basis within their respective procedures and relations. Giving definite form does not mean that the original sensations were unreal; it means that the form available for their later recognition has changed. Yet preserving some parts also excludes others. A hospital's records of diagnoses, examinations, medication, and expenses may not record who requested leave to stay at the bedside, who borrowed money to pay the bills, or who lost work opportunities because of caregiving. Medical records may bring pain into institutional judgment, but pressure from family care need not thereby acquire the same position. This also affects how rebuttals can be made: what has not been written down often requires other witnesses, supplementary materials, or explanation through other relations. Categories already recorded may also be reviewed, corrected, or set alongside other records.
The same applies to wedding and funeral exchanges. The occasion may involve hardship, embarrassment, silence, late arrivals, gifts sent through others, and explanations afterward. If a recorder writes down names and amounts, complex exchanges are compressed into a portion that can be entered in accounts, compared, and used to pursue reciprocation. The record is not false, but it cannot preserve the full thickness of the occasion. Records of wedding and funeral exchanges usually record attendance and amounts, but may not preserve why someone could not afford a gift, could not attend, or could only send a gift through someone else. The consequences of filtering also change with relations. Accounts of hardships not explained in the record may still be supplemented through concrete explanations.
Household registration and residence materials are also formed through concrete processes of registration, verification, and safekeeping. Someone has lived in a city for a long time, is known to neighbors, has children attending school, and has stable work. When these facts of life enter institutional judgments, they often have to pass through forms such as household registration, residence permits, rental registration, social insurance contributions, or supporting materials. Institutional personnel's recognition of these forms under rules does not amount to recognition of life in its entirety.
The same holds in other institutional settings. School staff record grades, attendance, sanctions, and comments under rules, yet may not be able to record all of a student's fear, family hardship, exclusion by peers, and silence. When courts handle contracts, evidence, amounts, deadlines, and responsibilities, they too may be unable to incorporate emotional debts, shame, and long-term mutual aid into the same form.
Filtering is more than technical deletion. Who records, under what categories, which materials are retained, and what standards of proof are used all affect who will later recognize differences, how they will do so, and what consequences the differences can enter. Recording personnel, institutional procedures, classification rules, and interpretive authority within relations jointly determine which differences can remain and which experiences will lack a place in future judgments. Giving definite form also makes experiences comparable: names, times, amounts, diagnostic labels, categories, and requirements of proof allow experiences otherwise difficult to set alongside one another to be compared within a procedure, while also downweighting the parts that cannot be entered in these formats. Giving definite form makes it possible to raise differences, but does not mean fully reproducing experiences as records. It enables later comparison while leaving room for supplementation, explanation, or dispute. It concerns the forms of recognition, rather than a final verdict on reality.
A node is not a neutral place of preservation. It both preserves social facts and changes the forms in which social facts can be recognized. Filtering produces unequal conditions of recognition. The fact that something is excluded does not mean it never happened; it is harder to identify in subsequent procedures and may be difficult to bring into a form that can later be recognized. Loss of a voice refers to insufficient conditions for recognition, not to facts never having occurred, still less to their being erased from reality. For example, sons and daughters who have provided long-term care for elders without leaving documents, witnesses, or recognition within the family may struggle to raise that care when family property is divided. Workers who have worked with injuries over a long period without medical records, coworkers' testimony, or work-injury materials may also struggle to bring bodily differences into compensation judgments. Pressure from care that medical records do not record may still be remembered among family members; conversely, categories that have been recorded may be questioned, supplemented, or understood anew. What is retained at different places of preservation can be mutually supplementary, but can also conflict.
V. Institutions and Relations: Formal and Informal Nodes
While a worker is moving goods, their lower-back injury worsens. The worker endures it for several days, then goes to the hospital because of the pain. Through consultation, examination, diagnosis, and billing, medical personnel enter part of this bodily experience into medical records and the system. It is the records left by treatment that make it possible for different people later to raise these materials under their respective procedures. Workplace staff may use the diagnostic certificate as a basis for leave requests or job assignments, while personnel involved in insurance relations may use the medical history for risk judgments. Staff determining work-related injury may address questions of responsibility using medical records, records of old injuries, accounts of the scene, and witness materials together. Family members may discuss care and how to share the burden on the basis of expenses and treatment records. These acts of handling are not one and the same judgment, nor do they necessarily lead to the same consequence.
Hospitals, schools, courts, local police stations, neighborhoods, workplaces, and state registration systems can perform formal node functions because their personnel, rules, procedures, and documents can convert certain facts of life into forms that institutions can handle. Once grades, sanctions, judgments, attendance, proof of residence, and public security records enter these procedures, they are usually easier to raise in matters of progression to the next level of schooling, compensation, punishment, welfare, job assignments, and judgments of eligibility.
But formal forms are not inherently more truthful. A worker saying they are in pain does not mean the relevant procedure will necessarily recognize a work-related injury. Someone who has lived in a city for many years may still be unable to enter channels for school admission, medical care, or welfare if their materials are incomplete. Formal nodes handle only differences that rules can identify; they do not encompass all the facts of life. Their efficacy comes from traceable duties and procedures and still requires personnel to operate them, interpret rules, and verify materials. Whether materials are complete and how procedures work both change the outcome of recognition. Traceability and reproducibility make formal materials easier to use across relations between strangers, but do not thereby negate the reality of experiences outside procedures, nor can they guarantee that every item of formal material suffices to determine a result.
Outside formal procedures, differences also continue to be retained and recalled. Wedding and funeral exchanges are often not one-off events. Who came, who was absent, who sent a gift through someone else, and who still showed up despite hardship may be remembered by family members, relatives, and neighbors, or written into records of exchanges. Years later, when borrowing, partnership, courtship and marriage, or elder care are at issue, people may raise these past relations again and interpret them differently. Relatives' memories of care, household division, borrowing, weddings, and funerals may not enter formal archives, yet may be raised again in family allocations, mediation, and everyday cooperation. Neighborhood reputation does not preserve itself or judge on its own either. It continues through people's recounting, confirmation, questioning, and circulation of accounts over repeated exchanges, affecting whether others are willing to lend money, enter a partnership, or introduce a prospective spouse. Even requests for help, quarrels, rumors, screenshots, and public statements in group chats may be retained, forwarded, or brought up again by group members. Whether they are effective depends on who preserves them, who raises them, who believes them, and what relations recognize them, not on any inherent evidential force in the records themselves.
Informal nodes need not pass through institutional procedures to produce consequences, but neither are they necessarily truthful or effective. In societies of acquaintances, local communities, and everyday cooperation, they may command strong recognition; they may also be questioned, forgotten, or rejected by formal procedures. The same memory of a relation may elicit opposite judgments among different participants. Whether it can enter into consequences depends on which concrete people raise it, on what occasion, whether anyone responds, and how past relations affect trust. Informal preservation may retain processes of interaction, care, personal bonds, and past explanations that official forms could not accommodate. That is its advantage. Its limits are equally clear: memories may be dispersed, reputation may be disputed, and accounts may carry unequal efficacy depending on relational position. It must not be romanticized as truth untainted by institutions, nor dismissed as ineffective because it lacks a formal format.
VI. Objects and Documents as Relay Carriers
Objects and documents are often seen as passive materials, yet they can carry differences already inscribed in them and leave relay positions for later retrieval. An IOU fixes the amount, relation, and agreement involved in a loan as evidence. Only when someone brings it before relatives or submits it to a court can it become part of later judgment. A contract is concluded by participants, and specific clauses set out responsibilities, rights, times for performance, and the consequences of breach. A contract is not text that enforces accountability by itself. Only when parties, mediators, institutional staff, or court personnel invoke it according to procedure can a relation enter handling in a particular form. Medical records retain diagnoses and the course of treatment; records of wedding and funeral exchanges retain attendance, absence, and ceremonial cash-gift amounts. They can make it easier for later participants to raise past differences, but cannot replace interpretation, recognition, and judgments about consequences.
Household registration booklets, residence permits, social insurance records, and rental registration fix some of people's relations to places, institutions, and eligibility. Genealogies, stone inscriptions, land deeds, and place names may also retain relations across generations and community memory. Objects and documents carry differences; they are not acting subjects capable of judging, preserving, authorizing, or passing things on by themselves. Through them, specific people can also extend the traceability of relations. A loan, an episode of diagnosis and treatment, or an instance of attendance might otherwise become difficult to raise again once the event has ended. Through writing, safekeeping, and repeated use, part of it can be brought into new settings later. Documents and objects can be preserved, copied, carried, and displayed. Only through such uses do specific people carry differences beyond the time and place of the original event and connect them to new relations and procedures. These uses carry forward differences that have already been handled; objects and documents do not interpret or decide on people's behalf.
VII. Authority to Extract Differences at Nodes: Who Can Make the Past Take Effect Again?
Preserving differences does not mean that anyone can retrieve them at any time. Consider medical records kept by a medical institution. Different people raise relevant contents for purposes of treatment, insurance, leave requests, compensation, or care, under their respective authority and within the corresponding procedures and relations. Who may access which materials, who is qualified to cite them, and who can bring them into judgment are distinct questions. Likewise, even if records of wedding and funeral exchanges are kept within a family or clan, this does not mean everyone can bring them out at will. Raising them while preparing a wedding or funeral may serve to arrange exchanges; raising them when borrowing money may serve to judge relations; raising them when dividing property may turn the issue into one of weighing past contributions and shortfalls. Whose account can be heard still depends on family and local relations and the specific conditions of recognition at that time.
Relevant personnel may retrieve records of school disciplinary sanctions when evaluating candidates for honors, considering progression to the next level of schooling, arranging transfers between schools, or meeting with parents. Memories among relatives may also be raised anew when property is divided, elder care arranged, or money borrowed. These cases show that authority, procedures, relational position, and interpretive authority always stand between the existence of material or memory and its gaining recognition. The power of nodes therefore lies not only in preserving differences, but also in determining just who can make differences take effect again.
Saying that nodes determine who can make differences take effect is, in essence, functional shorthand. In fact, institutions that keep materials, staff who retrieve documents under their authority, family members who can raise past relations, and personnel qualified to recognize or refuse materials jointly produce an uneven distribution of authority to extract differences. Preservation and authorization to extract must be clearly separated: a preserved difference is not one that everyone has authority to raise, still less one guaranteed recognition once raised. This uneven authority to extract differences also means that the past is not equally available to everyone in reality. Even when they know the past facts, people who lack channels for safekeeping, standing to provide proof, or relational support may struggle to make those facts part of public judgment.
Authority to extract differences is also constrained by rules of custody, privacy restrictions, family authority, institutional duties, and requirements of proof. Knowing about a difference does not automatically entitle someone to disclose or invoke it; being able to raise it does not mean being able to decide its meaning. Only by distinguishing each step—accessing materials, retrieving them, presenting them publicly, and bringing them into judgment—and distinguishing who bears the consequences can we avoid compressing preservation, retrieval, recognition, and consequences into a single automatic process. Different procedures allocate these steps to different people. Memories that seem easier to raise within family relations may require other forms of proof in formal procedures.
VIII. The Recasting of the Same Difference at Different Nodes
The same difference may be given different meanings when it enters different nodes. At a hospital, medical personnel handle a medical history as material for treatment. In some matters of insurance, leave requests, or job assignments, if specific rules permit or require it, that history may be examined alongside other materials. Within a family, it may be connected to care and the allocation of expenses; in courtship and marriage, it may be interpreted as a future risk. Both the authority to extract differences and the consequences vary from node to node.
Similarly, an old debt may mean a demand for repayment to a creditor, an evaluation of reliability within kin relations, material concerning responsibility in court proceedings, or reputation in local exchanges. An accent may bring closeness among people from the same home region, be marked as a risk in an exclusionary environment, become a difference mocked at school, or carry belonging within a national community. The meaning of a difference does not change on its own. Different institutional personnel, participants in relations, classification rules, and recognition procedures each extract different parts of a difference and connect them to different consequences. Nor is the meaning of a preserved difference fixed: which node it enters, who raises it, and on what grounds all affect the direction of consequences.
Different forms of preservation may also conflict. Pain not entered into medical records may be difficult for staff determining work-related injury to recognize on that basis. Relatives may remember care, yet if legal materials are insufficient, that care may struggle to acquire the same efficacy when property is divided. Local reputation may retain an absence without retaining its reason, and the person's explanation may be downweighted. What is called strength or weakness is not the result of nodes themselves contending with one another or adjudicating. Personnel, institutions, rules, and recognition relations in the current relational field give certain forms of preservation greater efficacy. In institutional procedures, medical records, contracts, household registration, judgments, and school enrollment records are usually more readily recognized. In societies of acquaintances, relatives' past relations, records of wedding and funeral exchanges, and local reputation may also affect borrowing, courtship and marriage, cooperation, and the division of elder-care responsibilities.
Formal and informal forms are not inherently more or less truthful than one another. Whether a form of preservation acquires efficacy depends on who handles it in the current relational field, what the rules recognize, what participants believe, and whether it can corroborate and be corroborated by other materials. Formal materials may not be valued among acquaintances, while informal memories may be supplemented and heard under particular circumstances. When recognition relations change, the efficacy of the same form of preservation changes too. Recognition on one occasion cannot justify the conclusion that it is effective everywhere, still less can nonrecognition on one occasion be understood to mean that the difference can never be raised again. Giving the same difference new definite forms at different nodes may produce tensions in its consequences: medical records may emphasize diagnosis, family discussion care, workplace arrangements job assignments, and local reputation reliability. Different participants handle differences according to different relational requirements; this is not simply a repetition of the same fact. Analyzing differences in relaying by setting them side by side is not equivalent to tracing a complete relational chain.
IX. Node Failure: How Differences That Are Not Preserved Lose Their Voice
Nodes can preserve differences, and missing links in preservation also produce consequences. A worker who has worked with an injury for a long time but has no medical records, witnesses, or work-injury materials may struggle to raise bodily differences in compensation procedures. The worker felt pain, endured it, and kept working; these facts have not disappeared, but lack a stable form through which to enter institutional recognition. Likewise, sons and daughters who have provided long-term care for elders without records or recognition from family members may struggle to explain their contributions when property is divided. People from elsewhere who have lived in a city for years but have incomplete materials may still face eligibility barriers to school admission, medical care, and welfare. Help given to relatives that no one remembers may also be difficult to turn into credit within relations when borrowing later. Differences not preserved at a node first of all lack a basis on which they can be preserved, retrieved, or raised, and can very easily lose their voice in future judgments.
Yet having a form of preservation does not guarantee efficacy. Nodes not recognized by the current relational field may likewise leave differences without a voice. Relatives remembering care does not mean court personnel will recognize it in the same way; patients saying they are in pain does not mean their workplace will recognize a work-related injury; neighbors knowing about long-term residence does not mean school procedures will recognize eligibility for admission; records of wedding and funeral exchanges preserving interactions does not mean institutions will recognize rights on that basis. Node failure may also arise from a mismatch between a form of preservation and current requirements: material has been retained but does not meet a procedure's format; witnesses exist but do not appear when needed; family members know about an experience but lack a sufficient relational position to secure a hearing for it.
These two situations must not be conflated as the same kind of loss of voice. If no form has been left that can be accessed later, the problem is a lack of a basis for preservation, retrieval, or presentation. If a form exists but cannot connect to current conditions of recognition, the material may fail to meet procedural requirements, or the person raising it may lack the authority or relational position needed to secure a hearing. Although both make it temporarily difficult for differences to produce consequences, a failure of recognition may arise either from the failure to preserve a difference or from preserved forms, authority, or relations failing to connect to current judgments.
Loss of a voice must not be understood to mean that something never happened, still less described as permanent ineffectiveness. It means that at a certain time, within a particular relation and set of conditions of recognition, a difference failed to enter into consequences in a sufficient form. When conditions change, materials are supplemented, witnesses appear, or relations are reorganized, differences previously difficult to raise may still be seen again. Remedying loss of voice therefore cannot rely on indiscriminately entering all experiences into a single kind of record. It must address separately the conditions for preservation, form, and obtaining a hearing, examining what materials, testimony, explanations of relations, or procedural supplements can give previously downweighted differences another chance to be heard.
X. From Nodes to Relational Chains
Nodes preserve differences, but cannot keep them in their original places forever. Workplace personnel may use bodily differences in medical records to arrange leave, while personnel involved in insurance relations may use them as risk materials. Household registration materials may be raised in different procedures at schools and hospitals. Records of wedding and funeral exchanges may be reinterpreted in borrowing or courtship and marriage. Once a difference retained at one node is brought into another, subsequent participants handle it anew in light of new relations, rules, and materials.
When a lower-back injury moves from medical records into leave arrangements, then into attendance, performance, income, debts, or relatives' evaluations, the difference no longer remains only at the hospital. When wedding and funeral exchanges move from records into judgments about borrowing, then into credit and family evaluations, new relational consequences also occur. Nodes are starting points for preservation and extraction, not containers that complete subsequent processes in advance. Someone carrying materials, memories, or traces from one node to another does not automatically constitute a complete relational chain. It means, first, that differences have left their original place of preservation and entered a new setting for handling.
