Public and political attention commonly peaks during acute response and then shifts elsewhere while insurance, permitting, reconnection, and rebuilding decisions continue. That decay amplifies inequity and explains why it is under-detected, but unequal recovery can still arise under sustained scrutiny, so Attention is a typical rather than universal constituent.

Recovery inequity typically contains attention decay because scrutiny often recedes during the slow restoration tail when access decisions lock in divergent trajectories.


Differential recovery is not yet inequity without a fairness standard that determines which differences are relevant and unjustified. Equity supplies that normative reference; the domain child fixes its object to allocation of restoration throughput after an incident and diagnoses systematic departure.

Calling restoration inequitable presupposes equity as the context-sensitive fairness standard against which access, timing, and end-state disparities are judged.


Insurance, title, political voice, administrative capacity, and social capital give better-positioned groups earlier access to settlements, contractors, and permits; that early position then compounds while delayed groups lose options. Increasing Returns owns the live cumulative-advantage identity historically called the Matthew effect; the child confines it to a post-incident tail.

Recovery inequity exposes cumulative advantage: better starting position accelerates access to restoration, and early restoration further improves later access within the recovery window.


The pathology is defined only in the bounded restoration tail after an acute disruption, when damaged or displaced systems move toward working endpoints. Recovery supplies that trajectory; the child adds population comparison, uneven access mediators, and a disparity in timing and terminal quality.

Recovery inequity presupposes a post-disruption recovery trajectory whose restoration speed and endpoint can diverge across affected groups.


Irrelevant conclusion supplies the genus: Prove a sound argument for a proposition that is not the one at issue, then treat it as settling the contested claim — a relevance failure caught by restating the question before grading the answer. Red Herring preserves that general structure while adding its differentia: Deflect a discussion by introducing material irrelevant to the open question, so attention and the conversational floor shift to the new topic and the original question is left feeling-addressed-but-unanswered — the test being whether the new material does any work on the claim that was open. The parent can occur without those added commitments, whereas removing the parent structure leaves no basis for classifying the child as this subtype. That asymmetry establishes subsumption rather than mere association.

Red Herring is a specialization of Irrelevant conclusion, retaining the parent's defining structure while adding the child's specific commitments.


Attention supplies an internal constituent: The selective allocation of a fixed processing capacity to some inputs while the rest are filtered out, surfacing scarcity upstream of every decision. Red Herring requires that role within this mechanism: Deflect a discussion by introducing material irrelevant to the open question, so attention and the conversational floor shift to the new topic and the original question is left feeling-addressed-but-unanswered — the test being whether the new material does any work on the claim that was open. Remove the parent-role and the child loses a required internal operation, even though the parent can exist outside the child. The child is therefore built from the parent rather than being a taxonomic kind of it.

Attention is an internal constituent of Red Herring; removing that role breaks part of the child's defining mechanism.


Redistribution is allocation specialized to a state-authorized collection-and-disbursement rule that moves resources along a named inequality axis. Allocation supplies the genus: Assign a limited supply across competing claimants under a feasibility constraint, independent of which criterion fills in the rule. Redistribution preserves that general structure while adding its differentia: The deliberate reallocation of income, wealth, or consumption between groups through state authority — a clearing-house collecting from a source base and paying a recipient base under rules set so the net flow runs from those with more to those with less along a named axis. The parent can occur without those added commitments, whereas removing the parent structure leaves no basis for classifying the child as this subtype. That asymmetry establishes subsumption rather than mere association.


Reference Deviation inherits the observation-versus-declared-reference relation and first-class departure judgment of Baseline Deviation, then specializes it to the four-role assertion architecture used in phenotype and comparable semantic annotations.

Reference deviation is baseline deviation specialized to ontology assertions with explicit bearer, quality, reference-state, and deviation roles.


The artifact externalizes positionality at decision time and binds each stance entry to what it changed in the analysis. Positionality supplies an internal constituent: Treat a knowledge claim as constitutively shaped by the knower's social and institutional location, and declare that standpoint up front so readers can grant partial credit — strong where access opened, silent where it was foreclosed. Reflexive Journal requires that role within this mechanism: A dated, contemporaneous first-person record in which a qualitative researcher externalises the assumptions, commitments, and positional influences shaping each analytic decision — converting an unavoidable observer-effect into a documented variable an auditor can trace to confirmability. Remove the parent-role and the child loses a required internal operation, even though the parent can exist outside the child. The child is therefore built from the parent rather than being a taxonomic kind of it.

A reflexive journal contains positionality as the dedicated record making researcher standpoint, access, occlusion, and methodological consequences inspectable.


Both preserve a contemporaneous parallel reasoning trace because the finished analytic artifact cannot reveal which priors, doubts, and frame shifts produced it. Memoing supplies the genus: Producing a parallel, contemporaneous, durable record of the in-flight reasoning that generates an artifact, so the trajectory survives alongside the artifact. Reflexive Journal preserves that general structure while adding its differentia: A dated, contemporaneous first-person record in which a qualitative researcher externalises the assumptions, commitments, and positional influences shaping each analytic decision — converting an unavoidable observer-effect into a documented variable an auditor can trace to confirmability. The parent can occur without those added commitments, whereas removing the parent structure leaves no basis for classifying the child as this subtype. That asymmetry establishes subsumption rather than mere association.

A reflexive journal is memoing specialized to observer stance, preserving in-flight assumptions and reactions alongside analysis and linking them to the decisions they shaped.


The journal turns the process back on its assumptions and records how self-description changed coding, sampling, questioning, and interpretation. Reflexivity (Self-Reference) supplies an internal constituent: Self-referential systems. Reflexive Journal requires that role within this mechanism: A dated, contemporaneous first-person record in which a qualitative researcher externalises the assumptions, commitments, and positional influences shaping each analytic decision — converting an unavoidable observer-effect into a documented variable an auditor can trace to confirmability. Remove the parent-role and the child loses a required internal operation, even though the parent can exist outside the child. The child is therefore built from the parent rather than being a taxonomic kind of it.

A reflexive journal contains reflexivity by making the observer's stance and its effects on analytic output an explicit input to subsequent analysis and audit.


It inherits the diagnostic trace, hidden design hypothesis, contextual test, predicted consequence, and refactoring probe. The child adds an inheritance edge, Liskov substitutability, refused contractual members, and replacement by delegation or a narrower shared superclass.

Refused Bequest is the code-smell species whose stubs, throws, or ignored inherited members provide defeasible evidence that inheritance was used for reuse despite a broken subtype contract.


The subclass accepts an inheritance edge yet stubs, throws from, or silently violates some inherited operation. That conduct is only diagnosable as refused bequest relative to the supertype-client contract and LSP's requirement that every promised behavior survive substitution.

Refused Bequest presupposes LSP because the smell is precisely a subclass refusing inherited obligations that substitutability requires it to honor.


Interface Mismatch supplies two locally workable sides, a required contract seam, and a gap between offered and required behavior. Refused Bequest inherits that structure and specifies the seam as an inheritance promise: the subclass reuses implementation while stubbing, throwing from, or mishandling members the supertype contract requires.

Refused Bequest is the object-oriented interface mismatch in which a subtype's offered behavior fails the supertype contract clients are entitled to require.


The live regression identity explicitly decomposes an outcome into a systematic function and a stochastic component whose distribution supplies the likelihood or loss interpretation, uncertainty estimates, and residual diagnostics. That probability-family commitment is an internal model constituent, not an external condition and not the kind of method regression is.

Regression contains a distributional assumption as the internal commitment that specifies its stochastic outcome or residual component.


Every live-definition regression commits to a systematic functional form from explanatory-variable vectors to an outcome value or distribution parameter. The surrounding method estimates that mapping from noisy data and adds stochastic residual, loss, validation, and interpretation apparatus. The mapping is therefore a constituent rather than the entire lifted identity.

Regression contains a function mapping as its systematic component from explanatory-variable inputs to an outcome value or distribution parameter.


A live-definition regression supplies a signal model through its systematic functional form, a noise model through its residual distribution, and an estimator-discriminator through its loss. It returns the fitted systematic component and a residual whose structure tests misspecification. Regression adds explanatory variables, coefficient or function estimation, and its three-use discipline to that complete signal-extraction genus.

Regression is signal extraction specialized to recovering a systematic input-output relationship from an outcome entangled with stochastic residual variation.


Every member of the live regression family learns from finite noisy data about an underlying outcome process or future observation under explicit model assumptions. It therefore satisfies statistical inference's sample-to-model-to-uncertain-conclusion genus, then adds a systematic outcome function, an explanatory-variable structure, a fitting loss, residual diagnostics, and the prediction/effect/attribution use discipline.

Regression is statistical inference specialized to estimating a systematic outcome function under an explicit stochastic model and loss.


The live RDD entry explicitly defines a quasi-experimental design that finds as-if-random assignment in an administrative threshold and contrasts this with an experimenter making assignment. It therefore satisfies the full natural-experiment genus in every in-scope case. It adds a continuous running variable, a sharp cutoff, continuity and manipulation diagnostics, the sharp/fuzzy estimand branch, a bandwidth choice, and local-only scope. A deliberately installed researcher cutoff would be a broader literature usage but falls outside this node's stated identity.

Regression discontinuity design is a natural experiment specialized to found as-if-random assignment at a sharp cutoff on a continuous running variable.


The venture's conclusion and committed operating model depend on a rule remaining stable. When that condition moves, the plan loses viability even if execution and demand remain sound. Model Assumption Failure carries that portable dependency break; dockets, courts, compliance, and monitorability supply the regulatory differentia.

Removing regulatory vocabulary leaves a plan stranded because a load-bearing environmental parameter was modeled as fixed when it was mutable.


Mathematical relations are the data primitive on which the relational model's typed tuples, closed operator algebra, and query rewrites operate. Relation supplies an internal constituent: Describes associations or dependencies. Relational Model requires that role within this mechanism: Organize data as typed sets of tuples queried by a small closed algebra of relation-to-relation operators, so any composition is itself a valid query, rewrites preserve meaning, and the logical schema is separated from physical storage. Remove the parent-role and the child loses a required internal operation, even though the parent can exist outside the child. The child is therefore built from the parent rather than being a taxonomic kind of it.


The worse problem may be real and the comparison sound, yet it establishes a ranking rather than the contested claim that the lesser problem is ineligible for attention. The severity direction and missing exclusivity premise distinguish this subtype from tangential red herrings and other target substitutions.

Relative privation is irrelevant conclusion specialized to a worse same-type problem whose severity rank is treated as a license to drop the lesser concern.


The fallacy's output is not merely an incorrect rank: the invoked worse case captures the audience's finite processing budget and filters out a conceded, addressable concern. The exclusivity audit asks whether that reallocation is actually required, but selective allocation occurs in the fallacious case too.

A scarce selective-processing budget is an internal constituent of the move that drops the lesser concern from a deliberative floor.


The relation compresses a production chain into a responsibility handle for availability, errata, withdrawal, rights, and successor releases. It does not certify that the party remains effective, but its defining semantic claim is the routing and assignment of responsibility.

Removing bibliographic machinery leaves a single addressable party bound to answer for the released form and its downstream governance consequences.


The publisher is not merely a contributor or distributor; the relation records the party whose standing makes the release operative and to whom release-state decisions are routed. A false or stale field may fail empirically, but the role the field purports to encode is release authority.

Removing the metadata field leaves a recognized, scope-bound right to effect and govern one artifact's release.


Presses, repositories, agencies, and registries ordinarily decide whether and in what form an artifact crosses the release boundary. Yet a publisher field can record a purely operational releaser in an automatic or open channel where discretionary selection is absent, so gatekeeping is not universal.

Stewarded publishing typically contains the gatekeeping core of an agent controlling passage through a release threshold into a downstream channel.


The metadata field establishes a checkable association between one released resource and one addressable releasing party. The child adds the release-versus- creation cut, stewardship scope, downstream query routing, and field-governance limits.

Publisher Relation is a directed Relation specialized to a released artifact, the agent responsible for release, and a release-time accountability scope.


Remove Stroop tasks, psychometric vocabulary, and group-versus-individual research aims and the surviving structure is uncertainty partitioned into true variation and observational error, with the ratio limiting usable discrimination. The paradox adds the purpose mismatch created when a design optimized for one variance component is reused for another.

The Reliability Paradox is a measurement-uncertainty failure localized by separating within-unit error from between-unit true-score variance.


Both summarize a relation between changing quantities by a characteristic exponent and distinguish proportional from disproportionate scaling. The child fixes the quantities to male and female size, the unit set to a phylogenetically controlled clade, and the exponent's side of one to the identity of the larger sex.

Rensch's rule is allometry specialized to disproportionate co-scaling of larger- and smaller-sex body size across related animal species.


Male competition or choice and female fecundity selection differentially retain size variants, turning a matched slope of one into the sign-predictable greater-than-one or less-than-one relation the rule names.

Rensch's rule presupposes natural selection because unequal selection gradients on the two sexes drive the allometric slope away from isometry.


Licensing, tariffs, quotas, budget lines, and protected franchises instantiate a named public-choice failure mode. Platform, procurement, prestige, or other non-state allocation systems can exhibit the trap outside the state's catalogue.

A Rent-Seeking Trap is a Government Failure when state rules create and defend the rent, but analogous institutional-allocation traps need not be governmental.


The transferred rent itself nets out between winner and loser. The welfare pathology comes from labor and capital spent on the contest and from the productive-frontier output those resources could otherwise have created.

The Tullock rectangle is the trap's internal deadweight loss: real contest resources consumed without producing an offsetting gain in total surplus.


A one-time dissipative contest is rent seeking but not yet a trap. The trap switch is persistence: winners fund coalitions, relationships, and rules that raise the forward-looking transition cost and manufacture further rents.

The trap contains Lock-In: accumulated rent-defence machinery makes switching to superior productive rules costlier than preserving the inferior regime.


The domain child adds a rule-created economic rent, a Tullock rectangle, productive-frontier counterfactual, and persistent rent-defending coalition. Its portable extraction-over-production core is already exact in the prime.

Removing Tullock accounting and public-choice furniture leaves the live Rent Seeking pattern of spending on allocation rules rather than new value.


Swapping self for other in initiation or completion changes the repair type, its expected sequential path, and the interactional meaning of the move. Conversation systematically affords the trouble-source speaker an earlier opportunity to repair, making self-initiated self-repair, other-initiated self-repair, and other-correction non-interchangeable positions. This directed preference is a constituent asymmetry, not a claim that every deviation is impolite.

Repair sequence contains an agency asymmetry because self- and other-repair positions are not interchangeable and are reached with a stable preference ordering.


Every repair sequence detects trouble in a shared conversational state, interrupts or locally modifies the primary exchange, invokes a meta-communicative move, restores sufficient alignment, and permits the talk to continue. Communication Repair supplies that genus. Repair Sequence adds the human turn-taking substrate, the trouble-source/initiation/completion skeleton, the self-versus-other agency coordinate, the sequential-position coordinate, and the empirically preferred routes through their grid.

A repair sequence is the conversation-analysis species of communication repair, specialized by an agency-by-position grid and a preference for self-repair.


The framework makes conversational trouble tractable by breaking an episode into three functional positions and then holding apart two questions ordinary talk fuses: who notices or repairs, and where in the sequence the move occurs. Those components can be analyzed independently and recombined to locate the episode in a finite grid, so decomposition is internal to the method rather than merely a way an outside analyst may describe it.

Repair sequence contains a decomposition that separates trouble source, initiation, and completion and cross-classifies them by agency and sequential position.


Same-turn repair, transition-space repair, next-turn initiation, and third-position completion have no identity outside a system that allocates a one-at-a-time conversational channel. Even self-repair within one turn is classified against the turn unit and its possible handoff. Turn Taking supplies that sequential interaction substrate; the repair organization diagnoses and resolves trouble within it.

Repair sequence presupposes turn-taking because its positions and agency classes are defined relative to turns, transition spaces, and who holds the conversational floor.


Fasteners, interfaces, manuals, parts horizons, tools, and software pairing are decisions made before failure that determine whether the artifact can be changed later. Repairability is the restoration-after-failure specialization of that lifecycle planning.

Repairability contains lifecycle adaptability because the original design must preserve a feasible path for later diagnosis, access, replacement, and support.


The scored property is valuable because it lowers the time, cost, and failure risk of the maintenance action. The child fixes that action to diagnosis, non-destructive disassembly, part replacement, and reassembly of physical artifacts.

Repairability contains Maintenance as the intervention that restores intended function after degradation or component failure.


Component boundaries and stable interfaces provide the decomposition required for local replacement. The child additionally requires physical access, documentation, tools, parts availability, economic viability, and software support.

Repairability contains Modularity because a failed component must be independently identifiable, removable, replaceable, and reconnectable without replacing the whole artifact.


It inherits predecessor, successor, stable role identity, explicit displacement, time asymmetry, operative-versus-preservation contexts, and a migration path. It adds DCMI replaces/isReplacedBy fields, hard-versus-soft lifecycle governance, and resource-registry traversal.

Replacement Relation is the machine-routable resource-metadata species of Supersession: a distinct successor displaces a predecessor in one role.


Representativeness is attribute substitution specialized to replacing a hard probability, frequency, or category-likelihood target with felt typicality. A hard target attribute is silently replaced by an easier correlated attribute and the proxy value is reported without the judge registering the swap. The substitute is resemblance to a category prototype or expected process pattern, and the characteristic failures appear when priors, sample size, or set inclusion disagree with that resemblance.


Representativeness is a heuristic specialized to using resemblance as a rapid, ecologically contingent rule for probabilistic judgment. Both replace an expensive or unavailable assessment with a tractable shortcut whose accuracy depends on how well its cue correlates with the target. The shortcut is a human typicality judgment and the target is probability, frequency, category likelihood, or generative-process plausibility.


Request maps to first-pair part; method, address, and correlation map to type conditioning; response/error maps to second-pair part and preference asymmetry; timeout maps to noticeable absence; retry/backoff/idempotency maps to repair. Network protocols and failure modes are the domain frame.

Removing network machinery leaves a typed initiating move that projects one causally paired response, makes its absence noticeable, and defines repair.


Natural method semantics or engineered idempotency-key deduplication makes repeated application collapse to the first effect. The edge is not strict: read-only exchanges may be side-effect-free, retries may be disabled, and a deliberately at-most-once call may accept loss instead.

When an effectful request can be retried after an ambiguous timeout, idempotence is the internal property that makes duplicate execution safe.


Reference Cadence Exceeds Tracking Bandwidth supplies a moving reference, a finite-bandwidth tracker, and persistent error when the reference changes faster than the loop can follow. Requirements Churn inherits that complete control structure and specifies the reference as project requirements and the tracker as the organization consolidating design and implementation.

Requirements Churn is the project-delivery species in which a changing specification outruns the execution loop's tracking bandwidth.


The requirements baseline is the target, engineering incorporation is the tracking process, and churn creates a target velocity that may outrun design, implementation, testing, and documentation. Short iterations and loose coupling reduce tracking lag; they do not make the objective stationary.

Requirements volatility is a non-stationary objective specialized to a software specification changing near or above the team's convergence rate.


The pathology is defined by a designated ready-state marshalling buffer and release function being absent, misplaced, unauthorized, or bypassed. Without that expected check-in, status, readiness, and single-release apparatus there is no specific gap between resources physically present and resources operationally assignable.

Resource staging failure presupposes the Staging Area function that should convert arrived resources into visible, ready, assignable capacity.


The requisition system assigns resources to named classes, but a class hides a capability spread larger than the receiving task can absorb. Classification is an internal constitutive mechanism rather than the failure's genus; the child adds delivery through mutual aid and arrival-time discovery of the task-fit gap.

Resource-typing mismatch contains a capability classification whose categories are too coarse for the task's operational tolerance.


Interface Mismatch supplies a producer, a receiver, a required exchange seam, and a gap between offered and required contracts. Resource-Typing Mismatch inherits that structure and specifies a mutual-aid system that offers a coarse resource label while the incident task requires a narrower capability hidden inside the class.

Resource-Typing Mismatch is the incident-command interface mismatch in which a requisition's offered class label fails the receiving task's capability contract.


With no context transformation there is no before-and-after layout relation to break. The child adds front-end breakpoints, reflow, trained scanning, and display-fidelity consequences to the general dependence of meaning on context.

Responsive-Layout Breakage presupposes context because the defect appears only when a viewport, device, locale, orientation, or assistive setting changes the conditions under which one layout is rendered.


Interface Mismatch supplies two locally workable sides, a required display seam, and a contract gap that breaks their composition. Responsive-Layout Breakage inherits that structure and specifies content that remains available while viewport, device, locale, orientation, or assistive transformation makes its spatial meaning unusable.

Responsive-Layout Breakage is the UI interface mismatch in which a rendered layout's offered spatial contract fails the transformed viewing context's requirements.


Removing viewport and interface vocabulary leaves an element-complete representation whose transformed arrangement no longer preserves task-relevant priority, adjacency, hierarchy, or prominence. After the human_computer_interaction frame is stripped away, the retained structural roles are those of Representational Structure Mismatch: A representation preserves its target's elements but misstates one or more task-relevant relations among them, so content can appear complete while its shape licenses the wrong traversal, inference, or action. Responsive-Layout Breakage adds the local frame and commitments expressed in its identity: Diagnose the silent UI failure where an interface's content survives a viewport, device, or locale transformation but its layout-encoded meaning — priority, adjacency, hierarchy, above-the-fold prominence — is lost, so a passing content-accessibility check actively conceals the defect. The parent pattern remains recognizable without that vocabulary, while the child is the framed realization of it. That preservation test establishes decomposition rather than taxonomic subsumption.


Responsiveness Channel contains Accountability because named respondents, response expectations, and an observable decision history make the maintaining body answerable for whether and how it acts.

Publicly inspectable response performance makes accountability a defining constituent of the pattern.


Responsiveness Channel contains a named, persistent intake surface through which requests enter. Without that Channel there is no addressable path for community input. Channel supplies an internal constituent: A bounded conduit between source and receiver whose capacity, alphabet, and noise profile are constitutive of what can cross it — a fact outside the channel's bandwidth, codebook, or noise floor is structurally inexpressible through it. Responsiveness channel requires that role within this mechanism: Turn vague openness to feedback into auditable accountability by requiring three co-occurring structures — a published intake surface, a documented response discipline, and a public decision log whose latency and rejection-with-reason rate anyone can read. Remove the parent-role and the child loses a required internal operation, even though the parent can exist outside the child. The child is therefore built from the parent rather than being a taxonomic kind of it.

A published intake channel is a defining constituent of a responsiveness channel.


Responsiveness Channel contains Commitment in the declared obligation to acknowledge, triage, decide, and explain requests according to a public discipline. Commitment supplies an internal constituent: An agent binds itself in the present to a future course of action or to the truth of a proposition, creating a new constraint on future behavior that others can rely on. Responsiveness channel requires that role within this mechanism: Turn vague openness to feedback into auditable accountability by requiring three co-occurring structures — a published intake surface, a documented response discipline, and a public decision log whose latency and rejection-with-reason rate anyone can read. Remove the parent-role and the child loses a required internal operation, even though the parent can exist outside the child. The child is therefore built from the parent rather than being a taxonomic kind of it.

A published response discipline turns receptivity into a standing commitment rather than an informal intention.


Responsiveness Channel contains Feedback as the requests, objections, and observations that move from the served community to the maintaining body and receive a documented response.

Feedback from users or contributors is the information flow the responsiveness channel receives and processes.


Responsiveness Channel contains Transparency because its intake surface, handling rules, decisions, reasons, and response latency must remain publicly visible for neglect or selective treatment to be detected.

A public decision log is the transparency constituent that makes channel performance auditable.


The intervention's warrant depends on the historical reference remaining viable under current conditions. A shifted climate, hydrology, sediment budget, or biotic context breaks that load-bearing premise. Model Assumption Failure carries the general dependency break; reference ecosystems and restoration practice supply the frame.

Removing restoration vocabulary leaves a target invalidated because the conditions assumed to sustain it no longer hold.


The target is treated as a fixed property of place rather than a function of changing conditions. That stability premise is the Stationarity constituent whose violation opens the viability gap. Model Assumption Failure records the resulting loss of warrant; neither parent substitutes for the other.

The error contains an assumption that the condition-generating process remains stable enough for the historical reference to stay viable.


Retinotopy is the visual-system specialization of a neighborhood-preserving topographic map with non-uniform magnification. Topographic Map supplies the genus: A source space is laid out on a substrate by a neighbourhood-preserving map with non-uniform magnification, so positions encode relationships and damage to a substrate region predicts a localised source deficit. Retinotopy preserves that general structure while adding its differentia: Preserve the two-dimensional layout of the visual field as a two-dimensional layout on visual cortex — adjacent points in the world projecting to adjacent neurons — an invertible map that lets a lesion predict a scotoma and a rotating stimulus reconstruct the map. The parent can occur without those added commitments, whereas removing the parent structure leaves no basis for classifying the child as this subtype. That asymmetry establishes subsumption rather than mere association.


A retrieval facet assigns resources to governed values along one explicit criterion. After the linguistics_semiotics frame is stripped away, the retained structural roles are those of Classification: Sorting entities into discrete categories by explicit rules, turning unbounded variation into a finite, reusable map for downstream reasoning and action. Retrieval Facet adds the local frame and commitments expressed in its identity: Expose one controlled descriptive dimension as an independently selectable and filterable axis whose values can be combined at query time with values selected on other axes. The parent pattern remains recognizable without that vocabulary, while the child is the framed realization of it. That preservation test establishes decomposition rather than taxonomic subsumption.


Removing catalog machinery leaves alternatives within one slot whose selected value combines horizontally with selections on other slots. After the linguistics_semiotics frame is stripped away, the retained structural roles are those of Paradigmatic vs. Syntagmatic Relations: Any structured system can be decomposed along two orthogonal axes, the vertical set of substitutable alternatives that could fill a slot and the horizontal chain in which selected items are combined. Retrieval Facet adds the local frame and commitments expressed in its identity: Expose one controlled descriptive dimension as an independently selectable and filterable axis whose values can be combined at query time with values selected on other axes. The parent pattern remains recognizable without that vocabulary, while the child is the framed realization of it. That preservation test establishes decomposition rather than taxonomic subsumption.


Independent facet filtering is a constrained information-location mechanism. After the linguistics_semiotics frame is stripped away, the retained structural roles are those of Search and Retrieval: Locate and extract information. Retrieval Facet adds the local frame and commitments expressed in its identity: Expose one controlled descriptive dimension as an independently selectable and filterable axis whose values can be combined at query time with values selected on other axes. The parent pattern remains recognizable without that vocabulary, while the child is the framed realization of it. That preservation test establishes decomposition rather than taxonomic subsumption.


The competitor set is a defining structural role: several cue-bound items have negatively coupled access under a selection event. Unrelated items that do not compete under the cue provide the control and are spared.

Retrieval-induced forgetting contains competition because a shared cue makes related memories rivals for selection and access before one target is retrieved.


Persistent below-baseline impairment on independent testing is the effect's discriminating mechanism, separating active suppression from a temporary output race or generic overlap. The live inhibition prime exactly captures an applied brake on an otherwise available transformation—in this case cue-to-recall access.

Retrieval-induced forgetting contains inhibition because retrieval recruits active control that downregulates the accessibility of related but unretrieved competitors.


Retrieval practice is learning specialized to a durable human-memory update produced by effortful cue-to-target recall rather than passive re-exposure. Learning supplies the genus: Durable, experience-driven update of an agent's internal state that carries forward to alter later behavior or prediction. Retrieval Practice preserves that general structure while adding its differentia: Actively recalling information from memory produces stronger, more durable retention than an equivalent period of re-studying, because the effortful generative act of producing a target from a cue reconstructs and strengthens the memory trace more than passive re-exposure does. The parent can occur without those added commitments, whereas removing the parent structure leaves no basis for classifying the child as this subtype. That asymmetry establishes subsumption rather than mere association.


The pathology is not the well-designed discipline and therefore is not its subtype. It arises when the receive, inspect-and-grade, route, and settle needs of that reverse flow are forced through infrastructure optimized for known-condition forward batches.

Returns friction presupposes the reverse-logistics problem object: a backward physical-goods flow whose constraints invert those of the forward chain.


Myerson and Harris-Townsend index the equivalence to interim best responses under the common prior. The broader Revelation Principle also has a dominant-strategy formulation, so this constituent is conditional on the Bayesian branch.

The Bayesian formulation contains Bayesian Nash equilibrium as the solution notion whose outcomes are preserved by the direct truthful construction.


Gibbard-Satterthwaite preserve dominant-strategy implementability when constructing the direct mechanism. The Bayesian formulation relaxes this to expected optimality under a prior, so dominance is conditional on this branch.

The dominant-strategy formulation contains truthful reporting as optimal for every profile of other agents' reports.


Outcome equivalence defines the safe transformation class, and analytical tractability selects the direct representation. Deployment qualities need not be preserved, matching the prime's separation of invariant semantics from operational cost.

The theorem rewrites an indirect mechanism into an operationally different direct truthful form while preserving its equilibrium outcome under an explicit equivalence.


The theorem's search-space reduction is precisely from arbitrary mechanisms to outcome rules satisfying truth-telling inequalities. Without that condition, the direct construction does not reproduce the original equilibrium outcome.

The Revelation Principle contains incentive compatibility as the constraint that makes truthful reporting an equilibrium in the constructed direct mechanism.


The theorem compares formats only after holding constant who receives the item as a function of type. Changing that rule, for example with a reserve price, moves outside the equivalence class and can change revenue.

Revenue Equivalence contains a fixed allocation rule as the invariant outcome mapping that pins expected payments across auction formats.


The property preserved is expected revenue; the transformation family is the set of auction formats sharing allocation and lowest-type rent; the theorem's risk-neutral independent-private-values conditions delimit the invariant regime.

Revenue Equivalence is invariance specialized to expected seller revenue under auction-format transformations satisfying fixed scope conditions.


It inherits a backward channel distinct from the throughput-optimized forward pipeline and the inversion of its design constraints. The child fixes the returned items as physical goods and adds receive, inspect-and-grade, recovery- route, and settlement stages under unknown condition and volume.

Reverse logistics is the physical-goods specialization of a separately designed return path whose constraints invert the forward channel's.


Evaluation is the inner criterion-bearing operation that maps a bounded object and relevant observations to a verdict, score, rank, or judgment. Review crystallizes that evaluation into a persisted four-slot artifact by binding it to an identified evaluator and warrant. Removing Evaluation leaves a record with no evaluative act or verdict to document; removing the review packaging can leave a complete but transient or private Evaluation.

A Review strictly contains an Evaluation and adds attribution, warrant, persistence, addressability, and documentary affordances around it.


Interpretation supplies meaning recovery from a representational substrate under a framework that makes some readings available and others unavailable. Rhetorical Listening specializes that operation to live discourse, seals parsing before rebuttal, and requires identification, difference, and accountability passes whose result constrains the eventual response.

Rhetorical Listening is the discourse-interpretation species that parses another's stakes, remaining difference, and the listener's own filter before response.


Remove the self-directed accountability pass and the method becomes ordinary other-directed listening. Reflexivity supplies the loop in which the listener models how their own investments shape what is audible and uses that model to regulate the response; the child adds the cross-difference discourse setting and three-parse sequence.

Rhetorical Listening contains reflexivity because its accountability parse turns the listener's own position and interpretive filter into an input to the hearing and reply.


It inherits the separation of locutionary form, illocutionary act, and perlocutionary audience effect. The child fixes interrogative locution, assertive or hortatory force, internal answer retrieval, and the inversion failure produced by a mistaken audience model.

A rhetorical question is the indirect speech-act species whose interrogative form performs an assertion or exhortation and leaves the audience to supply the answer.


Remove the partition and the apparatus loses its coordinate system and element-by-element failure diagnosis. Decomposition supplies the whole-to-parts move; the child fixes its slots to an exigence recognized as addressable, a mediating audience, and constraints that enable and limit discourse.

The rhetorical-situation apparatus contains a three-part decomposition of the occasion into exigence, audience, and constraints so that misfit localizes to a named slot.


The child populates every parent role with an announced debt-financed tax switch, households that foresee the intertemporal government constraint, private saving as their lever, self-interested tax preparation, and an engineered demand effect reduced by the offset. The child adds fiscal institutions, present-value tax arithmetic, strong enabling conditions, and empirical partial-offset diagnostics.

Ricardian equivalence is the prime's fiscal canonical case: forward-looking households anticipate the deferred tax and save the current windfall, offsetting the financing intervention.


The generic wrapper proof turns a supposed semantic-property decider into a halting decider. The theorem is not a subtype of the halting question; it requires that exact earlier impossibility and extends its consequence from termination to arbitrary non-trivial input-output behavior.

Rice's theorem presupposes halting undecidability as the reduction basis that generalizes the limit to every non-trivial semantic program property.


Universal computation, semantic non-triviality, and a total exact decider cannot coexist. The halting reduction proves that closure and forces static analysis to become incomplete, unsound, restricted, or annotation-assisted rather than universally exact.

Rice's theorem is axiomatic incompatibility specialized to total decision of non-trivial semantic properties of partial computable functions.


The incumbent and entrant initially overlap, the incumbent cedes speed, reach, or scale where the entrant is stronger, and it narrows toward depth, permanence, ceremony, privacy, or physicality. The law adds the contested inter-versus-intra-medium boundary and its status as a defeasible historical heuristic.

Riepl's Law is the media-history specialization of Competitive Niche Differentiation in which an older medium survives by consolidating around functions a new medium serves poorly.


Without hanging-wall-down normal-fault arrays, half-grabens, border faults, extensional focal mechanisms, and the diagnostic brittle expression of rifting disappear. Normal Fault supplies an internal constituent: A fracture in the crust where the hanging wall has dropped relative to the footwall along a plane dipping near 60°, whose hanging-wall-down dip-slip geometry is the diagnostic signature of horizontal extension in the crust. Rift Zone requires that role within this mechanism: A region of lithosphere under extensional stress, where the crust thins by ductile flow and normal faulting and subsides as support is removed — a staged progression from doming through grabens to breakup whose maturity is captured by the McKenzie β-factor. Remove the parent-role and the child loses a required internal operation, even though the parent can exist outside the child. The child is therefore built from the parent rather than being a taxonomic kind of it.

A rift zone contains arrays of normal faults as its brittle upper-crust deformation component.


A rift zone is the lithospheric-extensional specialization of strain localisation, focusing distributed deformation onto a narrowing axis that may break through. Both require initially distributed deformation, a focusing instability, narrowing of the active zone, and a possible breakthrough endpoint. The child fixes the material to layered lithosphere, the load to far-field extension, and the diagnostics to normal faults, grabens, beta-factor thinning, heat flow, and continental breakup.


Without syn-rift lowering and thermal-sag subsidence, the beta-factor cannot predict accommodation history and the rift loses a defining response to removed lithospheric support. Subsidence supplies an internal constituent: Explain the downward descent of the ground surface as loss or rearrangement of subsurface support, routed through one channel — a change in the Terzaghi effective-stress state — so any driver's cause and reversibility read off a single ledger. Rift Zone requires that role within this mechanism: A region of lithosphere under extensional stress, where the crust thins by ductile flow and normal faulting and subsides as support is removed — a staged progression from doming through grabens to breakup whose maturity is captured by the McKenzie β-factor. Remove the parent-role and the child loses a required internal operation, even though the parent can exist outside the child. The child is therefore built from the parent rather than being a taxonomic kind of it.

A rift zone contains subsidence caused by crustal thinning and post-rift thermal contraction.


Removing melt generation, dike transport, and eruption from a magmatic rift removes its heat-flow and volcanic co-signature but leaves amagmatic rifts intact. Volcanism supplies an internal constituent: Explain how internally generated magma ascends and releases at a planetary surface by placing every eruption in a two-parameter space of silica (viscosity) and volatile content (explosivity), with melt generated by three solidus-crossing routes bound to tectonic setting. Rift Zone requires that role within this mechanism: A region of lithosphere under extensional stress, where the crust thins by ductile flow and normal faulting and subsides as support is removed — a staged progression from doming through grabens to breakup whose maturity is captured by the McKenzie β-factor. Remove the parent-role and the child loses a required internal operation, even though the parent can exist outside the child. The child is therefore built from the parent rather than being a taxonomic kind of it. The typical qualifier limits the claim to the characteristic route, not a constitutive requirement of every instance; exceptions must retain the child's identity through another mechanism.

Magmatic rifts contain volcanism as dike intrusion and decompression-melt release along the rift axis.


The ring is not taxonomically a one-operation group. It contains an abelian additive group, an associative multiplication, and the distributive coupling that generates ideals, quotients, and the ring-specific axiom tier.

A Ring strictly contains a Group as its additive structure, with zero as identity and every element carrying an additive inverse.


Weil's companion anomaly is defined by what the natural repair of the Mehra–Prescott miss does to a second empirical target. Without the first puzzle's demand for a much larger equity premium, there is no reason to turn the shared risk-aversion parameter high enough to generate this distinctive rate-level failure. The domain-to-domain edge preserves that sequence and avoids flattening both puzzles directly under the same generic calibration node.

The Risk-Free Rate Puzzle arises when raising CRRA risk aversion to repair the Equity Premium Puzzle drives the same model's risk-free-rate prediction implausibly high.


Risk Transfer Without Reduction is the climate-adaptation specialization of risk migration, adding a voiceless destination and a maladaptation verdict to an unreduced displaced hazard. Risk Migration supplies the genus: An intervention that blocks a hazard at one site without absorbing the generative pressure behind it does not eliminate the hazard but relocates it across a permeable boundary to a less-monitored region, often where controls are weaker and measurement does not follow. Risk Transfer Without Reduction preserves that general structure while adding its differentia: The maladaptation pattern in which an adaptation or defence lowers risk at a protected site by displacing the unchanged hazard onto a voiceless neighbour, catchment, or future generation — because it acts on one node's exposure rather than the generative pressure. The parent can occur without those added commitments, whereas removing the parent structure leaves no basis for classifying the child as this subtype. That asymmetry establishes subsumption rather than mere association.


Without an explicit or recoverable assumption there is no RAT target. The method inventories propositions, estimates their uncertainty and consequence, and selects one for testing. Assumption is therefore an internal constituent rather than merely the subject matter surrounding the test.

The objects ranked and tested are propositions the plan treats as true and on which downstream work depends.


The method does not merely identify risk; it imposes an execution order over tests using consequence, uncertainty, upstream position, and test cost. Prioritization is the ranking constituent, while Value of Information explains why that ordering can reduce expected downstream waste.

RAT ranks competing assumptions by a rule so scarce testing effort goes to the highest-value question first.


The three-term risk ranking and cheapest-credible-test heuristic approximate the decision-theoretic comparison between acting now and acting after evidence. Value of Information carries that portable skeleton; the named RAT workflow and venture dependency graph supply the applied frame.

Removing lean-startup vocabulary leaves the rule of buying the evidence expected to improve downstream decisions most relative to its cost.


The intervention concretely reassigns finite right-of-way rather than merely closing capacity. Allocation supplies an internal constituent: Assign a limited supply across competing claimants under a feasibility constraint, independent of which criterion fills in the rule. Road Diet requires that role within this mechanism: Intentionally reduce a street's vehicle capacity and reallocate the recovered right-of-way to other uses — the classic four-to-three-lane conversion — because the throughput-maximising configuration sits below the joint optimum across safety, retail, and pedestrian function. Remove the parent-role and the child loses a required internal operation, even though the parent can exist outside the child. The child is therefore built from the parent rather than being a taxonomic kind of it.

A road diet contains allocation because it removes vehicle-capacity share and assigns recovered width to turn lanes, bikeways, sidewalks, parking, or public space.


The child fixes the valued dimensions and engineering gate while the prime supplies feasible-set and substitution structure. Trade-offs supplies an internal constituent: Balancing competing priorities. Road Diet requires that role within this mechanism: Intentionally reduce a street's vehicle capacity and reallocate the recovered right-of-way to other uses — the classic four-to-three-lane conversion — because the throughput-maximising configuration sits below the joint optimum across safety, retail, and pedestrian function. Remove the parent-role and the child loses a required internal operation, even though the parent can exist outside the child. The child is therefore built from the parent rather than being a taxonomic kind of it.

A road diet contains a trade-off because it exchanges vehicle-capacity performance for safety, pedestrian, cycling, retail, and public-realm value on a constrained frontier.


Removing WCAG, ARIA, HTML, and screen-reader vocabulary leaves independently implemented producers and consumers cooperating through an explicit stable specification. The domain child fixes that contract to the accessibility tree and requires programmatically determinable name, role, state, and value.

Robust Accessibility is interoperability specialized to semantic markup that current and future assistive technologies consume through a shared accessibility contract.


It preserves Musical Form's sections, identities, return/contrast relations, conventional template, expectation arc, and whole-work compression, then fixes the schemas ABACA/ABACABA and the refrain's orienting function.

Rondo is the Musical Form species whose sectional plan alternates a tonic refrain with contrasting episodes through periodic return.


The refrain's repeated reappearance, not mere similarity among episodes, constitutes Rondo. Musical Form captures its domain genus; Recurrence captures the separate portable return mechanism that makes A the form's memory.

Removing musical form leaves one identifiable state deliberately reappearing at measurable lags, each return interpreted through prior occurrences.


Rules-of-engagement ambiguity contains bounded operator latitude as the mechanism that temporarily fills a coarse rule's missing distinctions and fragments behavior when exhausted. Discretion supplies an internal constituent: Latitude granted to an agent to decide within bounded limits. Rules-of-Engagement Ambiguity requires that role within this mechanism: Diagnose frontline breakdown under time pressure as a grain mismatch — decision rules written coarser than the environment generates choice points — paid out of a finite discretion budget, relocating the fix from the operator's judgment to the rule, escalation path, and pre-positioned authority. Remove the parent-role and the child loses a required internal operation, even though the parent can exist outside the child. The child is therefore built from the parent rather than being a taxonomic kind of it.

A finite discretion budget is the constituent resource consumed when operators must bridge unresolved rule-to-situation gaps.


Doctrine grain and choice-point grain instantiate Resolution Matching exactly: a coarser rule collapses cases that require different actions, while the domain frame adds use-of-force authority, escalation, and operational legitimacy.

Stripped of military doctrine, the failure is a resolver whose grain is coarser than the smallest consequential distinction the task presents.


The pathology exists only where an advance-issued conditional permission structure governs autonomous action under time pressure; it is a defect in that rule's resolving grain, not a standalone decision failure.

The ambiguity failure presupposes a rules-of-engagement instrument whose permission boundary must answer frontline choice points.


Sales, operations, finance, and supply chain each maintain an internally defensible plan for the same future; their conflict remains latent until the execution layer consumes the plans together. The child adds firm functions, planning cadence, decision authority, and execution costs.

S&OP Disconnect is the multi-function operations-planning instance of subsystems persisting with incompatible models of one shared external state.


A headline size scalar reports adequate protection while location, composition, accessibility, or fit fails; this record-state gap is internal to the larger weakest-margin illusion. Record-Reality Divergence supplies an internal constituent: An authoritative record of an external state drifts from the reality it describes while remaining the basis for downstream decisions. Safety-Stock Illusion requires that role within this mechanism: Recognize that a buffer reported as adequate protection can be useless when disruption arrives, because effective protection is the weakest of five margins — size, location, composition, accessibility, and fit to the realised disruption — not the reported size alone. Remove the parent-role and the child loses a required internal operation, even though the parent can exist outside the child. The child is therefore built from the parent rather than being a taxonomic kind of it.

Safety-stock illusion contains a report-to-operating-reality divergence in which nominal coverage remains authoritative while effective protection has collapsed.


The held surplus is the object whose size, location, composition, accessibility, and disruption fit are jointly audited; without it the case is simple underprovisioning. Reserve supplies an internal constituent: Deliberately maintained surplus held beyond expected need so the system can absorb variation, uncertainty, or shock without failing. Safety-Stock Illusion requires that role within this mechanism: Recognize that a buffer reported as adequate protection can be useless when disruption arrives, because effective protection is the weakest of five margins — size, location, composition, accessibility, and fit to the realised disruption — not the reported size alone. Remove the parent-role and the child loses a required internal operation, even though the parent can exist outside the child. The child is therefore built from the parent rather than being a taxonomic kind of it.

Safety-stock illusion contains a deliberately maintained surplus whose nominal size is adequate but whose effective readiness is defeated by another margin.


Each forward step consumes prior state or output and advances a business operation through a sequence. The child adds service-owned commits, forward compensations, reverse-order recovery, irreversible-last ordering, and durable orchestration or choreography.

A saga is a pipeline specialized to ordered local transactions with a compensating reverse path for partial failure.


Every forward saga step commits atomically at one service boundary before the next proceeds, and each compensation is itself a forward local transaction. This part relation preserves the entry's crucial distinction between true local atomicity and semantic whole-operation recovery.

Local transactions are internal constituents of a saga even though the cross-service operation is not one global ACID transaction.


In the triple-network account, the other endpoint of the controlled handoff is the central executive network. Remove that endpoint and the network no longer performs the goal-directed side of its defining switch.

The salience network's switching role presupposes the central executive network as the externally directed content configuration it recruits or disengages.


In the triple-network account, one endpoint of the controlled handoff is the default mode network. Remove that endpoint and the claimed mediation between internally and externally directed cognition is no longer the same mechanism.

The salience network's switching role presupposes the default mode network as the internally directed content configuration it suppresses or recruits.


Detecting relevance alone does not define this network. Its characteristic operation includes disengaging one content network and engaging another as behavioral context changes, so mode switching is inside the mechanism.

Contextual mode switching is a required constituent of the salience network's control role between internally and externally directed cognitive configurations.


Remove the connected-node organization and only a list of brain regions remains; the large-scale functional unit is therefore literally a neural instance of the substrate-general Network abstraction.

A salience network is a distributed network whose function arises from coordinated interactions among connected neural hubs.


It preserves the live stock-flow unit distinction, temporal integration, memory, inertia, and lag between a positive net flow and visible stock-level failure. Accumulation supplies the genus: A stock grows or shrinks as the time-integral of its net inflow minus outflow, so stocks and flows live on different objects and cannot be equated. Salinization preserves that general structure while adding its differentia: The process by which dissolved salts accumulate in soil, water, or an aquifer until they exceed tolerance thresholds — a salt-budget failure (input minus output over time) whose pathway sets the remediation and whose reversibility is asymmetric. The parent can occur without those added commitments, whereas removing the parent structure leaves no basis for classifying the child as this subtype. That asymmetry establishes subsumption rather than mere association.

Salinization is the salt-in-soil-or-water specialization of accumulation, with concentration as a stock integrating salt input minus flushing, drainage, or leaching output.


Prevention-versus-remediation timing is load-bearing precisely because reversal cost and feasibility are asymmetric across the pathway typology. Reversibility and Irreversibility supplies an internal constituent: Actions or transitions may or may not be undone or reverted. Salinization requires that role within this mechanism: The process by which dissolved salts accumulate in soil, water, or an aquifer until they exceed tolerance thresholds — a salt-budget failure (input minus output over time) whose pathway sets the remediation and whose reversibility is asymmetric. Remove the parent-role and the child loses a required internal operation, even though the parent can exist outside the child. The child is therefore built from the parent rather than being a taxonomic kind of it.

Salinization contains a reversibility partition because pathway and scale determine whether drainage or flushing can restore the prior state or whether intrusion and meromixis are effectively one-way.


The visible collapse can be abrupt relative to the slow accumulation horizon, making the distance from the concentration threshold an essential diagnostic variable. Threshold supplies an internal constituent: Safe vs harmful levels. Salinization requires that role within this mechanism: The process by which dissolved salts accumulate in soil, water, or an aquifer until they exceed tolerance thresholds — a salt-budget failure (input minus output over time) whose pathway sets the remediation and whose reversibility is asymmetric. Remove the parent-role and the child loses a required internal operation, even though the parent can exist outside the child. The child is therefore built from the parent rather than being a taxonomic kind of it.

Salinization contains a threshold because a named salt concentration separates tolerated sub-response conditions from crop, biotic, or use failure.


A salt wedge is the estuarine saline specialization of a density current, with dense seawater propagating beneath lighter river water along a gravity-set interface. Both require a density contrast, gravity-driven underflow, a moving intrusion front, an interface with a lighter ambient flow, and mixing or friction that controls extent. The child fixes the dense fluid to seawater, the ambient to river freshwater, the geometry to an estuarine channel, and the opposing controls to discharge and tidal mixing.


It preserves the two-layer counterflow and closing salt balance while narrowing the forcing ratio to weak tidal mixing and a stable wedge geometry. Estuarine Circulation supplies the genus: The density-driven two-layer counterflow where a river meets the sea — light fresh water flows seaward on top while dense salt water intrudes landward along the bed, its regime set by the ratio of river buoyancy to tidal stirring. Salt Wedge preserves that general structure while adding its differentia: The wedge-shaped intrusion of dense saline water beneath a lighter freshwater outflow at an estuary mouth, whose sharp density interface tapers to a thin up-channel tip that migrates as an index of the river-versus-ocean force balance. The parent can occur without those added commitments, whereas removing the parent structure leaves no basis for classifying the child as this subtype. That asymmetry establishes subsumption rather than mere association.

A salt wedge is the sharply stratified, river-dominated specialization of estuarine circulation in which landward dense intrusion and seaward fresh outflow remain separated by a thin halocline.


The sharp halocline and resistance to tidal mixing are constitutive rather than incidental visual features. Stratification supplies an internal constituent: Layered separation of a system. Salt Wedge requires that role within this mechanism: The wedge-shaped intrusion of dense saline water beneath a lighter freshwater outflow at an estuary mouth, whose sharp density interface tapers to a thin up-channel tip that migrates as an index of the river-versus-ocean force balance. Remove the parent-role and the child loses a required internal operation, even though the parent can exist outside the child. The child is therefore built from the parent rather than being a taxonomic kind of it.

A salt wedge contains stratification because dense saline water remains layered beneath lighter freshwater across a persistent vertical salinity-density interface.


The child cannot state supply-funds-demand without the accounting map from output to factor income to consumption or saving and investment. Circular flow alone remains neutral about whether the loop closes behaviorally in a particular regime. Say's Law adds flexible clearing prices, no permanent hoarding, reliable loanable-funds conversion, and impossibility of a persistent general glut.

Say's Law presupposes the circular-flow identity that production generates equal income, then adds the contestable behavioral claim that every leakage returns as expenditure at full employment.


The law reduces macroeconomics to supply only after assuming all relative markets and loanable funds reach a balanced, full-employment state. The price mechanism is the adjustment process; equilibrium is the balanced state whose binding rules out a general glut. These are distinct roles, and the child adds the circular-flow premise and its monetary assumptions.

Say's Law presupposes economy-wide market-clearing equilibrium because its no-general-glut conclusion is the claim that aggregate excess supply cannot persist.


The authored law depends load-bearingly on prices, including the interest rate, moving without delay to eliminate excess supply and to make loanable funds absorb intended saving. Without that allocation-and-clearing mechanism, circular-flow accounting supplies no behavioral guarantee against hoarding or a general glut. The child adds the aggregate classical claim and its other assumptions.

Say's Law contains the price mechanism as the flexible price-and-interest adjustment that clears relative markets and routes saving into investment.


Early cohorts and tightly supported deployments often function as a curated pilot whose evidence may not estimate repeatable demand at scale. The relation is typical rather than strict because a venture can commit to premature scale without ever running a formally bounded pilot.

Scale-Before-Fit usually treats small, subsidized, or founder-led evidence as if it had already crossed the pilot-to-scale evidence boundary.


Validation and growth commitment are precedence-constrained stages. Sequencing supplies the dependency-sensitive order; the child names the venture failure produced when substantial scaling is placed before evidence of repeatable, unsubsidized demand.

Scale-Before-Fit's identity is an ordering violation in which commitment precedes the evidence that should license it.


The pathology is more than testing demand early: it commits hiring, facilities, inventory, acquisition spend, or other durable cost before repeatability is demonstrated. Sunk Cost and Irreversible Commitment supplies the lock-in that makes the ordering error consequential.

Scale-Before-Fit requires a substantial growth commitment whose fixed costs and obligations cannot be costlessly reversed after weak demand appears.


exact/close/broad/narrow/related is the cross-scheme fidelity species of a governed relation vocabulary, with inference limits and traversal action per grade. The five admitted mapping types form a closed governed vocabulary and every type stipulates symmetry or direction plus a safe consumer action. The child bridges independently governed schemes and specializes actions to exact substitution, loss warning, hierarchy climb or descent, and related browsing.


A broadMatch or narrowMatch is not merely low-fidelity sameness: it declares which mapped concept is above the other in specificity and forbids the reverse inference. Exact, close, and related mappings do not contain that level order.

Broad and narrow mapping grades contain a Hierarchy relation that licenses climbing or descending across schemes in exactly one direction.


The source reasons over mapping hops, route fidelity, one-to-many structure, and a gap inventory across the whole mapping set. Those are graph-topological properties independent of whether the nodes are thesaurus concepts, clinical codes, data fields, or regulatory categories.

Removing vocabulary semantics leaves a typed cross-scheme graph whose paths, weakest-link grades, reachability, and unmapped nodes remain first-class.


Every instance names source and target concepts and supplies a decidable association rule through exact, close, broader, narrower, or related mapping. The child adds independently governed schemes, versioned declaration records, weakest-link composition, gap inventory, and an executable fidelity contract.

Schema Mapping Relation is a binary Relation specialized by cross-scheme endpoints, a governed five-grade vocabulary, and per-grade inference limits.


The mapping keeps both source and target frameworks sovereign and records what can safely cross between them instead of merging either framework. SKOS grades, curatorial workflow, and gap ledgers are the knowledge-organization frame; the surviving cross-framework meaning conversion is conceptual bridging.

Removing controlled-vocabulary standards leaves a maintained bridge that carries concepts between incommensurable frameworks while naming fidelity loss.


The mapping set has a lifecycle separate from either scheme and must preserve the state under which a grade licensed downstream inferences. A close match may be upgraded, an exact match revoked, and old inferences audited against the declaration version that authorized them.

Versioning is a strict constituent of the governed mapping artifact: every bridge is assertable, reviewable, revocable, replaceable, and historically queryable.


Scope neglect is the observable failure of valuation to respond adequately to changes in magnitude. Its live identity explains that failure through an internal attribute-substitution operation: the hard scope-weighted value is silently replaced by affect toward a prototype case. The mechanism occurs inside the broader valuation phenomenon and produces its flat-response signature; a coefficient or symptom is not a taxonomic species of the cognitive operation that generates it.

Scope neglect contains attribute substitution as its defining internal judgment operation: scope-weighted value is silently replaced by prototype affect, producing the flat magnitude response.


It inherits parallel presentation and semantic layers, a meaning-bearing distinction encoded only in presentation, a model-bound consumer, and silent divergence. The child fixes the layers to a visual UI and accessibility tree and adds ARIA, platform APIs, WCAG, and assistive-technology diagnostics.

Screen-Reader Ambiguity is Presentational–Semantic Mismatch specialized to visual interface structure missing or wrong in the accessibility tree consumed by assistive technology.


Gap-filling is one of the process's three simultaneous outputs and is diagnostic evidence of which script was loaded. The exact live pattern-completion operation captures this inferential constituent without treating generic sequencing or social role as the process's genus.

Script activation contains pattern completion because the loaded script supplies unstated steps, roles, props, and default fillers from a partial cue.


The process cannot occur without a pre-existing script whose recognition conditions the cue matches. The script remains a representation rather than an internal activation step, so the relation is prerequisite rather than part-of or is-a.

Script activation presupposes a stored script because activation is the cue-triggered transition that loads that ordered role-bound representation from dormant knowledge into working memory.


Seamount Effect inherits Topographic Forcing's fixed-relief plus incident-flow mechanism: the obstacle deflects and lifts the current, creates wakes or trapped circulation, and localizes mixing and flux. It adds the stratified rotating ocean, the activation conditions for a seamount, nutrient delivery, biological aggregation, and fishery vulnerability.

The seamount effect is the submarine-relief specialization of a fixed boundary geometry reorganizing a passing flow.


It has explicit inputs, effective expansion steps, correctness and termination semantics, outputs, and time and space profiles. It adds an initial state, successor function, goal test, frontier-ordering policy, heuristic admissibility, and completeness and optimality guarantees.

A search algorithm is an algorithm specialized to exploring a generated state space by a frontier strategy until a goal or stopping report is reached.


It locates a goal state, path, or satisfying configuration in a larger possibility space under an explicit goal test and cost profile. The child narrows the broad activity to graph or tree exploration with named uninformed, informed, and local strategies and formal guarantees.

A search algorithm is search and retrieval specialized to machine- represented state spaces, generated successors, and frontier ordering.


Without a governed public form there is no display authority from which a variant can be withheld, no index-wider-than-display asymmetry, and no way to distinguish input-only acceptance from an ordinary alias or uncontrolled term.

Hidden status requires a separate sanctioned Preferred Label that the result displays after the hidden string has performed only its recognition role.


The hidden inventory remains recorded and searchable, each string resolves to the canonical concept, and no hidden form becomes its own identity. The child adds a retrieval/display split, silent-update privilege, and a non-endorsement tier for typos, retired, or disavowed strings.

Hidden Label is Alias-to-Authority Mapping specialized so a variant is accepted by the resolution layer but withheld from every public name surface.


Copy proliferation is dangerous because each carrier confers a scoped right to act. Delegation supplies the issuer, granted scope, holder, and recall relation; Revocation Closure independently supplies the global bounded-recall property that proliferation destroys.

Secret Sprawl presupposes delegated authority because the credential is a copyable carrier through which an issuer lets holders exercise access rights on its behalf.


The failure is diagnosed only against the lifecycle requirement that an issuer be able to invalidate every active credential manifestation within bounded time. Unknown copies and relying sites create the closure gap; the endpoint, secret, rotation, broker, and access-control machinery supply the domain accent.

Secret Sprawl is the credential-copy failure in which the actual live effect set outruns the issuer's invalidation paths and Revocation Closure collapses.


When the reachable real rate remains above the rate clearing desired saving and investment, expenditure rather than price adjustment gives way. The child adds the secular driver bundle, sub-zero natural rate, nominal floor, chronicity, and fiscal-over-monetary remedy.

Secular stagnation contains deficient aggregate demand as the quantity that absorbs the unclosed saving-investment and interest-rate wedge.


The diagnosis has three load-bearing legs: structural excess saving, depressed investment, and an institutional nominal floor. Removing the bound lets the rate clear the market and prevents the wedge from being absorbed as persistent deficient demand.

Secular stagnation contains the effective nominal-rate floor that blocks the central bank before it reaches the sub-zero market-clearing real rate.


A Sediment Budget is accumulation specialized to a bounded littoral or fluvial cell whose sediment stock integrates enumerated source and sink fluxes. Accumulation supplies the genus: A stock grows or shrinks as the time-integral of its net inflow minus outflow, so stocks and flows live on different objects and cannot be equated. Sediment Budget preserves that general structure while adding its differentia: Account for sediment as a mass-balance ledger of sources and sinks over a bounded coastal or fluvial cell, so the running balance — not the last storm — tells whether the shoreline is accreting, stable, or eroding. The parent can occur without those added commitments, whereas removing the parent structure leaves no basis for classifying the child as this subtype. That asymmetry establishes subsumption rather than mere association.


The child explicitly consists of entrainment, carriage, and deposition; the parent supplies the exact capacity-drop emplacement mechanism rather than a loose outcome label. Deposition supplies an internal constituent: The process by which material carried by a transporting medium is laid down where the medium's carrying capacity falls below its load — coarsest and densest first — so the deposit's geometry records the energy history of the transport that ended there. Sediment Transport requires that role within this mechanism: Loose grains are entrained by a moving fluid once shear exceeds their threshold of motion, carried in a mode set by the ratio of shear to settling velocity, and deposited as the carrier loses energy — sorting coarse-to-fine along the gradient into a graded deposit that records the flow. Remove the parent-role and the child loses a required internal operation, even though the parent can exist outside the child. The child is therefore built from the parent rather than being a taxonomic kind of it.

Sediment transport contains deposition as its terminating load-shedding stage when carrier competence falls below what the transported load requires.


Water, wind, ice, and density current change the force laws but not the dependency on a directed carrier movement from source toward sink. Flow supplies the prerequisite condition: Structured movement of energy, matter, or information. Sediment Transport operates against that background: Loose grains are entrained by a moving fluid once shear exceeds their threshold of motion, carried in a mode set by the ratio of shear to settling velocity, and deposited as the carrier loses energy — sorting coarse-to-fine along the gradient into a graded deposit that records the flow. If the parent condition is removed, the child relation becomes undefined or loses the mechanism asserted by this edge; the parent can obtain independently, so the relation is presupposition rather than subsumption.

Sediment transport presupposes flow because a moving carrier with rate, direction, field, and continuity supplies the shear that entrains and conveys the load.


Sediment transport is the granular-fluid specialization in which size, density, and settling response control continued mobility and therefore sort the transported population coarse-to-fine along the energy gradient. The mixed sediment load shares one carrier while per-grain transport properties govern retention in motion or dropout, changing downstream grain-size composition. The child fixes the carrier to water, wind, ice, or density current and the selection rule to Shields-Rouse entrainment, competence, and settling mechanics.


Shields and Rouse relations operationalize the regime boundary; the child is not merely continuous movement at a varying rate. Threshold supplies an internal constituent: Safe vs harmful levels. Sediment Transport requires that role within this mechanism: Loose grains are entrained by a moving fluid once shear exceeds their threshold of motion, carried in a mode set by the ratio of shear to settling velocity, and deposited as the carrier loses energy — sorting coarse-to-fine along the gradient into a graded deposit that records the flow. Remove the parent-role and the child loses a required internal operation, even though the parent can exist outside the child. The child is therefore built from the parent rather than being a taxonomic kind of it.

Sediment transport contains thresholds because grain motion begins only when shear exceeds a size-specific critical value and deposition begins when carrying capacity falls below load.


Without a fault divided into candidate segments, there is no spatial unit to label quiet, compare with neighbors, or rank by time since rupture. Fault supplies the prerequisite condition: A frictionally-controlled discontinuity in rock across which the two sides slip under tectonic loading — decomposed into discontinuity, stress field, and friction law, from which the friction regime selects quiet creep versus locked stick-slip rupture, and geometry fixes earthquake style and size. Seismic Gap operates against that background: Read prolonged silence on a fault segment as accumulated strain rather than safety — a renewal-process inference that ranks segments overdue against their recurrence interval as highest-hazard, valid only where segmentation and characteristic-recurrence hold. If the parent condition is removed, the child relation becomes undefined or loses the mechanism asserted by this edge; the parent can obtain independently, so the relation is presupposition rather than subsumption.

A seismic gap presupposes a segmented fault on which rupture history and locking can be assigned.


Both infer positive evidence from the non-occurrence of an event that a stated model expected. The child fixes locked plate-boundary segments, elapsed time relative to recurrence, elastic strain loading, and a contested increasing-hazard inference.

A seismic gap is absence-as-information specialized to an overdue fault rupture.


Seismic gap is the fault-segment specialization of an aging renewal inference, valid only where segmentation and characteristic recurrence hold. The parent supplies the genus and can occur without the child; the child preserves it while adding commitments the parent does not require.


Without continuous loading, stored strain, a frictional failure boundary, and abrupt release, elapsed silence cannot stand in for an outstanding strain budget. Stress and Rupture supplies the prerequisite condition: Accumulated tension leads to break. Seismic Gap operates against that background: Read prolonged silence on a fault segment as accumulated strain rather than safety — a renewal-process inference that ranks segments overdue against their recurrence interval as highest-hazard, valid only where segmentation and characteristic-recurrence hold. If the parent condition is removed, the child relation becomes undefined or loses the mechanism asserted by this edge; the parent can obtain independently, so the relation is presupposition rather than subsumption.

Seismic-gap reasoning presupposes elastic stress accumulation and eventual rupture on a locked segment.


Remove the practice of identifying a causal effect from observational data and the statement becomes an unused conditional-independence proposition, losing its role as an identification assumption with adjustment remedies. It is one premise used by several estimators, not the broader inferential enterprise or itself a method for estimating an effect.

Selection on Observables presupposes the Causal Inference activity whose observational treatment-effect conclusion depends on conditional exchangeability.


The statement that treatment assignment is independent of potential outcomes conditional on a named covariate set cannot be demonstrated from the analyzed data because one potential outcome is missing for every unit. It is nevertheless held as true to load the causal effect estimate. The child specializes assumption by fixing the proposition, inferential activity, failure mode, indirect probes, and conditioning discipline.

Selection on observables is an assumption specialized to treating conditional exchangeability as true so an observational causal conclusion can proceed.


The assumption is A independent of Y(0),Y(1) conditional on C. Only one of those outcomes is observed for a unit; the other is the contrary-to-fact result under the treatment state not received. Without those actual-versus- alternative outcomes, exchangeability has no causal estimand to identify and reduces to an ordinary association among observed variables.

Selection on observables presupposes counterfactuals because its independence statement ranges over each unit's mutually exclusive potential outcomes.


Ignorability asserts A is independent of the pair of potential outcomes given C. Within each covariate stratum, the joint distribution factors and treatment status carries no residual information about the untreated or treated outcome. Potential-outcomes variables, treatment labels, the identification guarantee, and adjustment toolkit are the causal-inference frame placed on the live prime's conditional factorization.

Removing the potential-outcomes frame leaves a conditional statistical- independence claim: knowing assignment adds no information once covariates are fixed.


Relating material to the self binds it to biographical, trait, goal, and affective associations, multiplying later retrieval routes. The child adds the self as the orienting referent, the self-versus-semantic recall contrast, and content-specific distortions; equally rich non-self schemas instantiate the parent instead.

Self-Reference Effect contains Elaborative Encoding specialized to the self-schema, normally the learner's densest and most extensively connected knowledge structure.


It is a strict Bias species because the attribution procedure has a known sign rather than random error: own success is shifted toward internal causes and own failure toward external causes. The child adds self-involvement, outcome valence, the internal/external cause loci, and self-image protection.

Self-Serving Bias is a stable ego-protective directional offset in causal accounts of one's own successes and failures.


Removing the child’s frame leaves the reusable structure named by Motivated Reasoning. The child’s frame can be removed while the parent roles remain, so the edge records portable structural cargo rather than taxonomic identity.


Responsibility Attribution supplies the underlying outcome-to-source assignment, including the control-relevant internal/external cause loci. The child is a directional corruption of that operation, not a kind of neutral attribution: ego protection moves success credit inward and failure blame outward.

Self-Serving Bias distorts the operation that assigns causal credit or blame for an evaluable outcome to the self, circumstances, or other agents.


Semantic narrowing and widening is a specialization of semantic shift: it names two directional sub-types of meaning-change identified within Bréal's broader typology. It inherits semantic shift's four-part structure — the lexical item, the diachronic trajectory, the typology of mechanisms, the social-pragmatic-cognitive forces — and particularizes it to the scope-change axis. Narrowing is the specialization-direction sub-type; widening is the generalization-direction sub-type; both are species of the broader shift category.

Semantic narrowing and widening is a kind of semantic shift in which a word's reference set contracts or expands over time.


Without a socially maintained form-to-meaning binding there is no stable form whose interpretation can drift, no earlier and later signified to compare, and therefore no semantic-shift identity.

Semantic shift presupposes a conventional binding between a stable signifier and a signified whose community-governed meaning can change over time.


The domain abstraction scores feature overlap between temporal neighbours and predicts confusion when their difference is insufficient. The cognitive window, encoding competition, recall tests, and buffering interventions are its domain accent; generic sequencing is not attached because the live sequencing prime means deliberate precedence-constrained optimization rather than mere order.

Removing the working-memory and recall frame from sequential clarity leaves emphasized difference between adjacent units in an ordered field.


Remove requester and target roles, persuasion, compliance, social mediators, and experimental procedure. What remains is a deliberate choice over temporal ordering in which the first step changes the conditions under which a later step operates, and rearranging the same elements changes the objective outcome. The domain node adds the paired-request repertoire and human influence mechanisms.

Sequential Compliance Technique is the persuasion-domain form of Sequencing: the requester chooses an order because the same target request produces a different outcome after a state-changing precursor.


The U-shaped recall curve is explicitly composite. Its elevated first positions are produced by extra rehearsal and durable storage, and this limb survives a filled delay even when the recency limb disappears.

The serial-position effect contains the primacy effect as its durable beginning-of-sequence limb.


The U-shaped recall curve's elevated final positions arise from transient-buffer residence and temporal distinctiveness. A filled delay selectively removes this limb, demonstrating that it is a separable constituent rather than another name for the whole curve.

The serial-position effect contains the recency effect as its delay-sensitive end-of-sequence limb.


The server is authorized to reach internal metadata, loopback, or protected services; the caller is not. Accepting the caller's URL without preserving intent provenance makes the server issue the request on its own standing, composing outsider intent with deputy authority by union rather than intersection.

SSRF is the web-request form of a confused deputy: an outsider supplies intent while a trusted server supplies network position and credentials.


It binds future fulfillment behavior for a relying party and narrows commitment by stochastic-demand metric, percentile threshold, measurement window, and operational breach trigger. Commitment supplies the genus: An agent binds itself in the present to a future course of action or to the truth of a proposition, creating a new constraint on future behavior that others can rely on. Service Level preserves that general structure while adding its differentia: Commit in advance to fulfilling a stated quantile of stochastic demand — not its average — within a stated window with a breach consequence, and size the system's buffer against that tail, so each additional nine costs disproportionately more reserve. The parent can occur without those added commitments, whereas removing the parent structure leaves no basis for classifying the child as this subtype. That asymmetry establishes subsumption rather than mere association.

A service level is a commitment specialized to a measured fulfillment quantile, time window, and predeclared consequence for breach.


The post-failure expectation supplies a lowered comparison point and the remedy can sharply exceed it, increasing satisfaction. Yet the paradox's stronger claim—loyalty above the no-failure baseline—also depends on what the recovery reveals and on its moderators, so positive disconfirmation explains an important pathway without exhausting or strictly defining every case.

Expectancy Disconfirmation is a typical constituent of Service Recovery Paradox because failure lowers the immediate reference and an exceptional remedy produces a large positive performance-minus-expectation gap.


A strong terminal recovery commonly improves the remembered episode out of proportion to its duration, but the service-recovery effect is empirically conditional and can also be carried by diagnostic signaling and expectation disconfirmation. Peak-end weighting is therefore a supported riding mechanism, not a strict requirement of every observed above-baseline recovery.

Peak-End Rule is a typical constituent of Service Recovery Paradox because an exceptional recovery can become the overweighted positive ending in the customer's retrospective evaluation.


The paradox is not merely that a bad event is followed by a good one. Its defining explanation is diagnostic: an isolated failure creates an occasion on which a rapid and generous response can reveal otherwise hidden type. Signaling supplies that costly-action inference, while the child fixes it to a provider-customer failure-and-recovery episode and an above-baseline loyalty outcome.

Service Recovery Paradox contains Signaling because an unusually costly, observable remedy supplies credible evidence of provider competence and care that a smooth baseline cannot.


The construct relates material placed at one point in an authored account to a later event that activates it for an audience. Without an emplotted sequence of events there is no earlier plant, later return, retrospective earnedness, or distinction between unused preparation and arbitrary resolution.

Setup and Payoff presupposes a narrative whose ordered events can make an early element relevant to a later development.


Remove characters, props, plot, audience satisfaction, and craft judgment. The surviving relation is an ordered pair under dependency: the first element establishes information, capability, or constraint that the second uses, and reversing the order destroys that enabling relation. That is Sequencing specialized by narrative earnedness and retrospective interpretation.

Stripping the storytelling frame leaves a precedence-constrained sequence in which an enabling or expectation-bearing element must occur before the event that activates it.


Shannon-Hartley is the Gaussian continuous-channel specialization that computes the channel-capacity bound from bandwidth and signal-to-noise. Channel Capacity supplies the genus: Any information-bearing medium has a hard upper bound on reliable throughput that effort cannot exceed. Shannon–Hartley Theorem preserves that general structure while adding its differentia: Compute a noisy channel's maximum error-free bit rate as C = B·log₂(1 + S/N), a bound that is at once a wall no code can beat and a target codes can approach, linear in bandwidth but only logarithmic in signal-to-noise. The parent can occur without those added commitments, whereas removing the parent structure leaves no basis for classifying the child as this subtype. That asymmetry establishes subsumption rather than mere association.


It inherits subordination to one named decisive outcome, indirect value, priority flow toward the main effort, and the risk of orphaning when that effort changes; it adds an external field-state target, mediating model, lead-time, and reversion window.

A Shaping Operation is the field-conditioning species of Supporting Effort: its value reaches the decisive outcome through another operation rather than by achieving that outcome directly.


Shaping Operation is a strict specialization of Preparatory Field Conditioning. The parent supplies the genus and can occur without the child; the child preserves it while adding commitments the parent does not require.


Both contain a response that rises to an interior optimum and falls as the same driver increases further. The child fixes the response to organismal performance, the driver to an environmental factor, and the two declining arms to stress shoulders terminating at lethal limits.

Shelford's law is the organismal environmental-factor specialization of an inverted-U response with an optimum between harmful deficiency and excess.
