Chapter 35. Limited Distinction Extraction and Entry into Concrete Relational Fields
I. Explanation Cannot Begin with an Ultimate Answer
Faced with a concrete event, explanation must first answer how to begin. Adding another domain at this point does not answer that question. After an event occurs, people often ask: ultimately, is it class, the state, the market, the nation, the family, or the platform? These images are not meaningless. Those using them can extract real differences such as labor, certification, prices, shared memory, care responsibilities, or account records, forming judgments with partial explanatory power.
Distinction extraction within a limited scope does not mean that an overall explanation is correct, still less prove that the entities named by an image exist. Analysts can extract real differentiating units such as labor, wages, property, housing, debt, risk, domination, and available exits, but cannot infer class entities from these materials. This chapter's use of limited distinction extraction does not alter the established judgment that class theory belongs to Model C from the outset. This chapter's task is simply to establish how concrete events enter analysis; it does not repeat the full argument concerning Model C here.
If interpreters settle on an ultimate answer before encountering an event, subsequent materials will serve only to fill in the predetermined image; differences, nodes, and consequences not accommodated by the image in advance may remain outside their view. An ultimate answer often offers a convenience: it quickly tells people what to look for, yet also readily leaves no place for unexpected differences. Beginning with the event may be slower, but every judgment can return to concrete materials and processes of handling. Analysts can still use images of the state, market, or family, or other images, provided they disclose their scope of validity and do not let the images answer for the event in advance.
A concrete event is not a casually chosen example. It must contain identifiable actions, people handling matters, and consequences: someone makes a demand, someone accepts or rejects materials, a particular form of eligibility is being established or interrupted, and a relationship may change as a result. Social Differentiation Network Theory begins here precisely because preliminary judgments must establish who is handling matters, how materials are required, which relations have been implicated, what differences are extracted or occluded, and which consequences have already occurred. If an event is reduced to grand terms such as “inequality,” “marketization,” or “family problems,” analysts still do not know which differences have actually entered into consequences. Across different events, moreover, the order, kinds, and intensity of the relevant dimensions vary; they are not fixed steps completed in sequence every time.
At the beginning of explanation, the accounts of those concerned, documentary records, procedural requirements, and observers' descriptions may differ. Analysts need not immediately select one piece of material as the ultimate answer, nor can they abandon judgment because materials conflict. A more reliable approach is first to distinguish who produced each piece of material, which event it concerns, what it can establish, and which parts it does not cover.
The starting point of an event may also be disputed. A child's school admission can begin when the family prepares materials or when the school refuses to accept them; an unpaid-wages event can begin when wages fall due or be traced further back to contracting arrangements and the formation of work records. Which starting point to choose depends on the question the analyst is answering. The starting point is only the entry into the current window; it cannot be presented as the sole true beginning of the whole matter.
Interpreters must also retain their own position in the account. Which materials they see, which records they cannot access, and which stretch of events they use to delimit the event all affect preliminary judgments. Acknowledging these limits does not weaken analysis. On the contrary, it allows those who come later to check the grounds for a judgment and identify where revision should begin when new materials appear.
II. The Relational-Field Window and the Unfolding of a School-Admission Event
A child in the family of a worker from elsewhere really does live in the city. Every day he leaves the residential compound where his family rents a home; his parents work nearby, and neighbors have seen him. These facts of life do exist, but school personnel cannot complete an eligibility review solely on the grounds that “everyone knows he lives here.” They require proof of residence, a rental contract, the landlord's filing, community registration, proof of the parents' employment, and continuity of social insurance, and require the family to submit the materials within the prescribed time.
Poverty and household registration may both matter, but explanation cannot stop at these two names. If the actual obstacles at present are the landlord's failure to file, the end of the application period, and the student-registration procedure not accepting materials, analysts must trace how these differences acquire weight. The fact of the child's residence has not disappeared; it has simply not been successfully extracted through materials and procedures. Entering the relational field therefore also involves identifying which differences are occluded.
This shows that the relational field is the state of relations in which a concrete event is already situated, not a frame manufactured by the interpreter. A child's school admission already implicates family cash flow, the fact of residence, the landlord's filing, community registration, continuity of social insurance, school places, application deadlines, and student-registration materials. A worker's unpaid wages already implicate contracting relations, wage records, coworkers' testimony, rent, arbitration, and family expenses. A mother taking platform orders already implicates account scores, response times, care responsibilities, bodily condition, customer evaluations, and payment records.
The relational field precedes the window because relations in an event do not wait to be named by an analyst before they occur. There are already specific actors and consequences involved in whether the landlord files, whether the school accepts materials, and whether coworkers are willing to testify. Analysts may see some of these relations and temporarily miss others. Their omissions limit the explanation but do not make those relations cease to exist.
The relational field must not be written as an entity driving the event from behind the scenes; it describes only the actual state of these relations within the event. Omitting their bearers makes it easy to misrepresent a state of relations as an actor with a will. Relations themselves do not extract or determine differences on their own. Concrete personnel, organizations, and procedures actually make demands, preserve documents, refuse to provide proof, or change eligibility: school personnel review admission eligibility on the basis of materials and link admission to student registration; landlords decide whether to cooperate with filing; community personnel register or issue proof under procedures; workplaces and coworkers provide or refuse to provide proof; and platform account records and allocation procedures change opportunities to take orders. Concrete personnel, organizations, materials, rules, and procedures jointly carry the handling and consequences within the event.
In the school-admission event, the application deadline is only a procedural condition limiting the conversion of materials; it cannot handle the event on its own. Family cash flow is a real difference affecting whether parents can take leave, make the rounds to obtain materials, and maintain housing; it likewise has no capacity for autonomous action. Listing the school, landlord, community, deadline, and cash flow serves only to check who is handling matters, on what materials, which conditions constrain that handling, and how consequences form. It does not claim that the list exhausts every relation. The kinds of nodes, their sequence, and their weights can differ across events; these distinctions cannot be copied into a fixed procedure for every event.
A relational-field window is an analytical boundary that interpreters establish from clues in an event. It cannot be drawn arbitrarily, nor is it a container that never changes once established. Too small a window misses nodes that have already changed consequences; too large a window brings every possible background into the core analysis. Interpreters need to adjust the window in light of new materials, nodes' responses, relational changes, and consequences, allowing it both to expand and to narrow. The window carries an explicit analytical responsibility: including the landlord in the school-admission event requires explaining how filing affects residence materials; including the parents' working hours also requires showing why taking leave, submitting materials, or replying is affected. If there is no traceable connection between a background condition and current eligibility, risk, evaluation, or responsibility, it can temporarily remain outside the window.
Several overlapping windows may form around the same event. Parents care about whether the child can enter school on time; school personnel care about whether materials can enter the student-registration procedure; the landlord cares about the responsibilities that filing brings; and the analyst tries to see how these positions connect. Different windows do not mean that everyone speaks past everyone else. The materials they provide can be compared and may reveal differences invisible from a particular position of handling.
Materials have their own times of formation. A rental contract may have been signed long ago, while filing must wait for the landlord's cooperation; proof of the parents' employment comes from their workplaces, while community registration requires another set of information. If the family learns which document is missing only as the deadline approaches, the problem is not merely “incomplete materials.” It also concerns when the notice arrived, who can supplement and correct the materials, and which procedure remains willing to accept them.
Different materials may also contradict one another. The address on the contract may not match the actual residence, community registration may differ from the landlord's account, and the parents' employment records may be interrupted by job changes. School personnel must handle these differences within a limited time. Analysts cannot treat the final “approved” or “not approved” as the complete course of events; they must preserve how materials were compared, interpreted, and selected or set aside.
The family is not restricted to waiting passively. Parents may seek out the landlord to sign additional documents, ask their workplaces for supplementary proof, explain their living arrangements to community personnel, or ask the school what avenues for supplementation and correction remain. Whether these actions take effect depends on whether the relevant personnel accept the materials and whether the procedure still allows revisions. Retaining the positions from which those concerned act can prevent the family's predicament from being written as a natural outcome.
Reasons for adjusting the window should be recorded. New testimony brings contracting relations into an analysis of a workplace injury, and the window expands accordingly; materials already explain a deposit dispute, while the distant real-estate cycle has not yet changed its current handling, so the window can narrow. Such adjustment does not aim to finish everything at once. It keeps the scope of analysis close to the consequences taking shape. Materials sometimes point to different event boundaries. The school's time of receiving materials, the time parents began preparing documents, and the time the landlord refused to cooperate may each form a different starting point. Analysts must choose an entry point according to the question asked and retain the other timelines. This both clarifies the current problem and avoids using a single starting point to occlude antecedents and subsequent developments that already exist.
The space outside the window is not blank. Background conditions temporarily excluded may still really exist; there are simply no materials currently showing that they have entered into handling. If analysts write “not included” as “nonexistent,” they mistake an analytical boundary for a boundary of reality. Conversely, if every real background condition is placed at the core, the window loses its capacity to identify present consequences. Nor must the window include the family's entire life at its core. Parents' educational expectations, the child's classroom performance, and peer relations may become important after admission. If the present dispute concerns only whether materials can enter the student-registration procedure, they can temporarily remain in the background. When the event shifts from eligibility review to classroom life and evaluation, the analytical window can adjust accordingly.
III. Limited Distinction Extraction and Verification of Candidate Differentiating Units
A differentiating unit is a unit of difference in the world that can be distinguished, represented, assigned weight, and brought into comparison, and that may be extracted, connected, transmitted, and written back within a concrete relational field, thereby changing an object's position, eligibility, risk, evaluation, responsibility, action, or consequences. It is not a fixed factor, a variable, a smallest social atom, or a purely conceptual label, nor does it produce consequences on its own apart from real bearers. The differences in the world that can enter social events are inexhaustible. Income, household registration, age, language, educational qualifications, bodily condition, family position, familiarity with a locality, account records, debt deadlines, medical records, student registration, coworker relations, neighborhood reputation, shared memory, and silent records may all acquire relatively high weight in particular events. Potential infinity does not mean that every difference is already taking effect in reality, nor that all are equally important.
Limited distinction extraction is precisely the interpreter's extraction, from inexhaustible latent differentiation space, of the differences that currently need to be traced, on the basis of materials, people handling matters, relational chains, and consequences already implicated in the event. It is not arbitrary selection, nor does it mean that only a finite number of differences exist in reality. Inexhaustibility does not cancel comparison and judgment. Judgments can hold provisionally while remaining open to revision through counterexamples and subsequent materials.
Potential infinity means that analysts cannot list every potentially relevant difference in advance. Language, bodies, time, equipment, memory, and local relations can all be subdivided further, and the same difference can connect to new nodes. This does not require interpreters to include infinite contents at once; it reminds them not to mistake the current list for the final structure of the world. Any concrete event extracts only some of these differences. For example, school personnel require proof of residence, the landlord refuses to file, the application deadline approaches, and the student-registration procedure cannot accept the materials. These are the differences that connect in the current school-admission event and change its consequences; others can temporarily remain in the background. If subsequent materials show that certain personnel or procedures have retrieved those other differences, analysts can still revise the original window.
Whether a difference can enter analysis depends on whether clues already connect it to the event. Clues can come from requirements for materials, actions by those concerned, procedural responses, changes in eligibility, or the transmission of consequences. They can also appear in the explanations of those concerned, differences in documents, requirements raised by procedures, or sudden changes in consequences. When materials are rejected, the reasons for rejection provide new candidates; after a successful appeal, new materials that led to the changed judgment also deserve to be traced. For example, if parents' working hours have already affected taking leave and submitting materials, they enter the school-admission event. If no relevant materials are currently available, analysts can first record them as awaiting verification rather than immediately assign them high weight. The sources of candidates should be recorded so that analysts do not write their own suppositions as known facts of the event.
Interpreters can propose candidate differentiating units on the basis of requirements for materials, nodes' responses, relational changes, the transmission of consequences, and the retrieval of records. Proof of residence, the landlord's filing, community registration, and student-registration status in a school-admission event; proof of an employment relationship, medical records, and testimony in a workplace-injury event; and contracts, transfers, photographs, and chat records in a deposit event are all merely analytical entry points awaiting verification.
The representation of a differentiating unit may also change with the materials. “Unstable residence” can serve as a summary in a preliminary account and may later be divided into lease duration, number of moves, the landlord's filing, and commuting distance. Conversely, several scattered records may be combined into a single eligibility judgment in the current procedure. Subdivision, combination, and renewed representation must all be constrained by the concrete event; there is no eternally fixed smallest unit. Candidates may therefore contain or overlap one another. “Residence materials” can include a contract, filing, and community proof; “time pressure” may take the concrete forms of an application deadline, the cost of taking leave, and the time materials arrive. Analysts can adjust the level of representation to the event's needs, but cannot treat a higher-level summary and one of its component details as two independent causes within the same comparison, creating a false impression of quantity.
Candidates are not already confirmed causes. Interpreters must still examine whether concrete personnel, organizations, or procedures have extracted a candidate, whether it has acquired enough weight to enter comparison, and whether it has traveled along relational chains and changed eligibility, risk, evaluation, responsibility, or opportunity. A difference with only general relevance that has not yet entered present consequences can temporarily remain in the background; subsequent materials may also bring it back into the core analysis. Nor can the same difference be detached from relations and treated as a fixed factor. Household registration may enter directly into eligibility in one school-admission review but provide only background in another event. Care responsibilities may change the timing of material submission or cease to be an obstacle because someone shares them. The fact that a difference bears the same name does not mean it occupies the same position in every relational field. Analysts must trace the personnel, materials, and procedures that carry it.
Limited distinction extraction permits temporary omissions but requires that they be corrigible. If a preliminary window excludes a language difference and later communication records show that it is affecting the understanding of materials, analysts should add it. If verification shows that a candidate difference has entered neither handling nor consequences, it can also leave the core. For example, the landlord was initially thought to have refused filing, but later materials show that filing was completed and the actual problem lies in continuity of student registration; a negative review seemed to affect order opportunities, but subsequent records show that the account restriction came from another action in handling the matter. Removing a candidate that does not hold is part of revising the analysis, not proof that raising the earlier question was itself worthless. Both inclusion and removal require reasons grounded in materials. A candidate list cannot establish its completeness through length. Listing dozens of identities, resources, and backgrounds without explaining who extracts them in the current event still fails to enter the relational field. A shorter candidate set can be more useful than a vast inventory if it corresponds to materials, nodes, and consequences. Its value depends on verifiability, not the number of entries.
Conclusions reached through limited distinction extraction can have different strengths. When materials show only that a difference may be relevant, the conclusion should remain provisional. A judgment can be strengthened only when multiple independent materials point to the same handling node and counterexamples still cannot overturn the connection. Making the strength or weakness of evidence explicit does more to keep explanations revisable than hiding what is unknown behind an assertive tone. Such limitation does not turn judgment into subjective preference.
When several analysts propose different candidates, they can return to the same body of event materials for comparison. An analysis has better-supported preliminary judgments if it identifies people handling matters, materials, nodes, and consequences more accurately; explains why materials were accepted or rejected and where relational chains broke; accommodates contrary evidence; and is willing to narrow or revise its conclusions when new materials appear. Comparison does not require every disagreement to disappear immediately, but should locate disagreements where they can be examined. A limited model that can be traced and accepts calibration can still have greater explanatory power than a closed total image or arbitrary speculation.
IV. How Causality Comes Down to Relational Connections
The impulse to seek a root cause easily compresses a complex event into a total image declared in advance. Social events still have causes, and causal analysis remains valid. Opposing a root cause declared in advance does not deny causality; it requires causal judgments to rest on verifiable connections. Interpreters need to distinguish which differences materials and procedures have already extracted, which mechanisms temporarily have relatively high weight, which relational chains can be verified, and which answers were simply declared the sole root cause before analysis began. Materials failing to arrive may interrupt an eligibility review; missing wage records may make responsibility difficult to establish; account restrictions may directly reduce opportunities to take orders. New materials can support, limit, or overturn all these judgments.
Causal judgment cannot stop at naming concepts. A child's school admission is not automatically caused by the word “poverty.” Poverty must enter consequences through rent, the cost of taking leave, the preparation of materials, continuity of social insurance, residential stability, school places, and application deadlines. Nor are a worker's unpaid wages automatically caused by the words “labor situation.” The facts of labor must pass through contracting relations, wage records, coworkers' testimony, arbitration materials, and enforcement procedures before becoming responsibilities and consequences that can be handled. Likewise, low income does not determine a mother's order opportunities on its own. Those implementing platform rules allocate opportunities to take orders according to scores, negative-review records, time online, and customer evaluations preserved in the account; care arrangements and bodily fatigue also limit when the mother can respond to orders. Only by explaining who extracts differences, through what materials they acquire weight, and how they are transmitted and change consequences does causal judgment become concrete.
An event often contains several levels of causes. The landlord's refusal to file is the immediate condition behind the current break in the flow of materials, while rental relations and local registration arrangements provide more distant conditions. Family cash flow affects whether parents can move or take leave and may in turn change the responses available to them. Compressing causes at different distances into a single level makes it harder to explain which difference acquires weight where. Causal chains may also break. Even with a lower family income, a child may still enter school without difficulty if the landlord is willing to file, materials are supplemented and corrected, and school personnel can receive them in time. Conversely, a family whose income is not low may still be blocked by incorrect materials, a missed deadline, or problems with continuity of student registration. Counterexamples do not cancel the importance of income differences; they only limit overstrong conclusions such as “income necessarily determines the outcome.”
Talk of root causes also readily occludes positions of responsibility. If unpaid wages are attributed entirely to a distant structure, who keeps shift schedules, who confirms wages, who refuses to provide materials, and who is responsible for processing claims may disappear within the total image. Tracing concrete nodes can retain the more distant background while keeping current responsibilities and entry points for correction visible. Analysts may offer deeper explanations, but must show how they enter the current event. If the regional economy changes employment arrangements, connections through contracting arrangements, wage records, or job stability must be found; if educational resources affect places, it must be explained how those places translate into review outcomes. Without these intermediary links, macro-level concepts can serve only as provisional background.
Causes are not confined to actions that produce adverse outcomes. Someone submitting supplementary materials, being willing to testify, extending the time for accepting materials, or correcting old records may interrupt an existing relational chain and redirect consequences. If analysis looks only for sources of pressure without recording how corrections occur, it will write the event as advancing in one direction and miss the actual positions at which those concerned and the personnel handling it change the outcome.
Explanation must also distinguish actors' intentions from the consequences of their actions. A landlord's failure to cooperate with filing may arise from concerns, negligence, or refusal to bear responsibility. For the school-admission event, analysts must first establish how this action blocks materials. Intentions can enter analysis when materials support them; gaps cannot be filled with conjecture. Verifiable consequences do not mean that analysts have already grasped all of the other person's motives.
V. How Questions Change the Point of Entry: Workplace Injuries and Deposits
A worker strains his lower back while carrying goods on a night shift. A coworker saw him stop and brace himself against a wall; he visited a small clinic and may also have had imaging done. The injury really occurred, but that does not mean responsibility has been formally recognized. Personnel determining whether an injury is work-related need proof of the employment relationship, shift records, witnesses at the scene, medical records, the time of the accident, the workplace's stance, training records, and claim materials to connect the fact of injury to a determination of responsibility.
The workplace-injury entry point shows that bodily facts and institutional recognition must not be conflated. The workplace's denial of an employment relationship, medical records that do not clearly state where the injury occurred, coworkers' unwillingness to testify, or claim materials that fail to arrive may all keep the fact of injury from reaching a determination of responsibility. Lack of formal recognition does not make pain disappear, nor can the reality of pain directly replace materials required by procedures. How strongly these differences bear on subsequent eligibility, responsibility, and consequences for life will be traced fully through a labor dispute in the next chapter.
A tenant from elsewhere cannot recover the deposit when ending a tenancy. Rent, the deposit, and the landlord's bargaining power may carry relatively high weight, but those handling the dispute do not consider only the everyday fact that the tenant “lived here.” They examine contract terms, transfer records, photographs of wear and damage to the property, repair responsibilities, the timing of the tenancy's end, the handover of keys, property-management fee arrears, and chat records.
The tenant may have moved out on time, cleaned the rooms, and returned the keys. If the contract did not specify standards for wear and damage, the deposit was paid in cash, there were no photographs at handover, and the landlord describes old wear and damage as new, actual residence and maintenance become difficult to turn into materials that mediation, complaint-handling, or litigation personnel can confirm. The facts have not disappeared; they have simply not acquired enough weight in the current procedure to change the judgment. “Wear and damage” in a deposit dispute also requires concrete representation: marks on walls, equipment malfunctions, the state of cleanliness, and missing items may be carried by photographs, handover inventories, repair records, or the two parties' accounts. When landlord and tenant interpret the same mark differently, the personnel handling the matter must check when it formed, how responsibility was agreed, and how strong a conclusion the available materials can support.
Cash payments and transfers leave different materials. A transfer can establish that a sum moved, but its purpose must still be judged alongside annotations, the contract, and chat contents. If there is no receipt for cash, later exchanges between the parties or other witnesses may also supply supporting material. The form of materials changes the difficulty of proof, but cannot be taken directly as the truth of the event.
Both parties may provide new materials. The tenant can add move-out photographs and handover messages, while the landlord can present repair documentation or contract terms. Analysts should not fix either side in advance as the only credible party. Who produced the materials, how they relate to the dispute, and whether they can be tested against counterexamples provide the basis for current judgment.
Failure to recover the deposit first constrains cash flow for the next rental, then narrows the time available to move, affecting commuting, dropping off and picking up children, job stability, and familiarity with a locality. These are immediate consequences; they do not mean write-back has already formed. If those concerned or relevant institutions preserve the outcome of the deposit's handling and the contracts, transfers, photographs, and chat records as differences that can be extracted again in the future, write-back has formed. Preservation itself does not mean these contents will necessarily govern subsequent judgments. Only when concrete personnel identify, extract, interpret, or assign weight to them anew through mediation, complaint-handling, or litigation procedures in later disputes does the content of write-back take effect again; it can then support, refute, or revise earlier judgments in light of new materials.
When the deposit event ends also depends on the analytical question. If the only question is whether the deposit can be returned, the window can close once a handling outcome has formed. If the question is how that outcome affects the next rental, cash flow, moving deadlines, and commuting arrangements enter a new relational chain. The earlier window provides materials and the later window takes up the write-back; the two need not be conflated into one infinite event.
VI. Adjusting Windows and Passing from One to the Next
When expanding the relational-field window, analysts cannot push all distant background conditions into the core analysis. A child's school-admission event can be traced back to urban policy, the regional economy, historical migration, education finance, the real-estate market, population administration, and still more distant social changes. If these backgrounds have not yet changed admission eligibility, application deadlines, school places, proof of residence, and the handling of student registration through current personnel, materials, or procedures, they need not be forced into the core.
Analysts should place at the window's core nodes and differences that have already entered actual handling through concrete personnel, materials, or procedures and changed the event's consequences. Nodes and differences that materials indicate are about to change eligibility, risk, evaluation, relations, or write-back, but that have not yet entered actual handling, should be listed as candidates awaiting verification, not brought directly into the window's core. Ordinary background should not be brought directly into the core either. If new materials confirm that candidates awaiting verification have entered handling, both the window and preliminary judgments need corresponding adjustment.
Without narrowing, analysis spreads without limit; without expansion, it misses crucial nodes. Technical tools cannot automatically supply an appropriate boundary. Interpreters must choose provisionally within concrete events on the basis of materials, counterexamples, and consequences. They must be able to explain the grounds for these choices and allow subsequent revision. Three kinds of change indicate when a window needs expansion: new materials point to another person handling matters; a new node begins to change eligibility or responsibility; or the original explanation cannot accommodate counterexamples that have occurred. If any one of these changes appears, analysts should examine whether the original boundary is too narrow. Reasons for expansion come from the event, not the pursuit of theoretical all-inclusiveness.
Narrowing also has grounds in materials. A background condition is important but has not entered current handling; a relational chain has broken and no longer transmits consequences; or a dispute, once checked against new materials, no longer makes a difference to the current conclusion. Such situations allow analysts to move the relevant contents back into the background and concentrate on nodes still operating. Different questions produce different stopping points: a study of whether a child can enter school can end its window at eligibility and student-registration handling; a study of how the admission outcome affects family life must continue to trace commuting, working hours, and cash flow. Provided the questions and boundaries are stated, the same event can admit several limited analyses without their competing for a single complete window.
The window should also distinguish the unknown from the irrelevant. When materials are lacking, analysts can say only that a difference has not yet been verified; they cannot directly declare it irrelevant. Only after verification establishes that it has not entered current handling is there reason to place it in the background. This distinction prevents insufficient materials from being written as nonexistence and keeps everything unknown from permanently occupying the core. When narrowing, it is best also to record reasons for exclusion: one background condition has no supporting materials yet; one node has been checked but has not changed consequences; one distant relation currently lacks traceable intermediaries. All three can remain outside the window, but for different reasons. When new materials later appear, analysts can identify where to re-examine without unfolding the entire event from the beginning.
Stopping expansion does not declare explanation finished. Once the current window can explain who handles materials, how differences enter consequences, and where the main counterexamples lie, while identifying what remains unverified, analysis has grounds for provisional closure. This stopping point serves the current question; it neither closes off the event nor prevents other questions from forming new windows.
After provisional closure, analysis can still reopen. New testimony, corrected records, subsequent handling, or unexpected consequences may make an old window inadequate. Reopening does not mean the earlier analysis failed in its entirety. Provided the original judgment explicitly stated the scope of its materials, it can be retained within its original range of validity, while the newly added parts undergo calibration.
Entering the relational field establishes a starting point for tracing, not a conclusion about weights. Analysts should be able to state which question about the event they are answering, which materials and people handling matters lie at the window's core, which candidates await verification, which differences temporarily remain in the background, and which nodes and relational paths are currently identifiable. These contents have no fixed order and do not constitute an operational checklist completed once and for all.
The fact that materials have been presented establishes only that they have entered the view of those handling the matter. Extraction does not mean acquiring high weight, and a difference not being extracted does not mean it does not exist. Further comparison of how a difference changes eligibility, risk, evaluation, responsibility, and consequences for action also requires tracing how nodes handle materials, how consequences are transmitted, how records are preserved, and whether counterexamples can change preliminary judgments. Chapter 09 has established the basic account of weight; Chapter 36 will take up comparison, recording, and calibration in actual events from this starting point. The responsibility this chapter leaves is to make the scope of limited distinction extraction and the remaining differences explicit, so that subsequent judgments of weight have materials to return to and nodes to examine, and the window can reopen when new relations or counterexamples appear.
