Anchor Semantic Neighborhood Publication

Mechanism

Each anchor in the adaptive index maintains a structured semantic neighborhood description as first-class governed metadata. The description is a tuple of (i) a set of semantic tags that classify the content domains the anchor governs, (ii) a set of operation classifications enumerating the traversal moves and content actions the anchor will admit, (iii) a governance specification declaring the credentials, depth profiles, and admissibility predicates a visiting discovery object must satisfy, and (iv) a connectivity manifest enumerating adjacent anchors with the type and weight of each edge. The neighborhood is not the content itself; it is a compact, structurally bounded summary that allows external evaluation without speculative traversal.

Discovery proceeds as a sequence of credentialed traversal steps. A discovery object resident at an anchor enumerates the connectivity manifest, retrieves the neighborhood publications of each reachable anchor, and scores each candidate against its cognitive state. The score combines a semantic alignment term, derived from the overlap between the anchor's neighborhood tags and the object's intent vector, with a governance admissibility term, derived from whether the object's credentials satisfy the candidate anchor's governance specification. Only candidates with both positive alignment and full admissibility are eligible for traversal. The selected candidate receives the discovery object, which then re-enters the same evaluation loop from its new position. Traversal records are written to the discovery lineage, capturing the anchor visited, the neighborhood description that justified the visit, and the credentials presented at admission.

Neighborhoods are recomputed whenever the anchor's governed content materially changes. The architecture distinguishes structural mutations, which require neighborhood republication, from content edits that fall within the existing tag set and require no republication. Republication is itself a governed operation, signed by the anchor's governance authority and timestamped against the lineage. Visitors that arrive holding stale neighborhood descriptions are reconciled at admission: the anchor presents its current neighborhood, the visitor either re-evaluates or aborts the traversal, and the lineage records the reconciliation.

The credentialed traversal protocol enforces a separation between description, evaluation, and admission. Description is the act by which an anchor publishes its neighborhood; it is unilateral and does not depend on any specific visitor. Evaluation is the act by which a discovery object scores published descriptions against its own intent; it is local to the discovery object and does not commit any state at the anchor. Admission is the bilateral act by which the anchor accepts the discovery object after verifying credentials; it is the only step that mutates lineage. This separation means that neighborhood publications can be cached, indexed, and broadcast without exposing the anchor to speculative traversal load, while admission remains a tightly controlled boundary at which governance is enforced.

Operating Parameters

The neighborhood description has a bounded representational size. The tag vocabulary is drawn from a registered semantic ontology whose cardinality is on the order of thousands of distinct tags; an individual neighborhood typically declares between three and twenty active tags. The operation classification set is similarly bounded by the architecture's enumerated operation types. The connectivity manifest scales with the anchor's structural degree, which in practice is bounded by deployment policy to keep evaluation cost predictable. The total serialized neighborhood description for a typical anchor falls within a few kilobytes, allowing a discovery object to retrieve dozens of candidate descriptions in a single round trip.

The scoring function is parameterized by weights on semantic alignment, governance admissibility margin, traversal cost, and recency. Deployments tune these weights to favor exploration, exploitation, or strict policy adherence. The admissibility term is gated rather than weighted: a discovery object whose credentials fail the anchor's governance specification scores the candidate at negative infinity regardless of semantic alignment, ensuring that governance is not tradable against relevance. Refresh cadence for neighborhood publications is parameterized per anchor; high-mutation anchors republish more frequently, while stable anchors republish only on structural change.

Discovery objects carry their own bounded parameters. Each object has a maximum traversal depth, a hop budget that decrements with each admitted traversal, and a credential set whose membership is fixed at object instantiation and may not be expanded mid-traversal. Intent vectors are typically updated as the object accumulates context, but updates are governed: an intent shift that would expand the object's effective scope beyond the credentials it holds is rejected. The combination of fixed credentials and bounded hop budgets makes individual discovery objects predictable in their resource consumption and limits the blast radius of any compromised object. Neighborhood publications additionally carry a freshness epoch; objects that consume publications older than a deployment-specified staleness threshold are required to refresh before scoring, ensuring that admission decisions are not based on materially outdated state.

Alternative Embodiments

In a first embodiment, neighborhood publications are dense vector embeddings computed from the anchor's content corpus, paired with a discrete governance specification. Scoring uses cosine similarity in the embedding space combined with a hard admissibility check. In a second embodiment, neighborhoods are symbolic predicates over a registered ontology, and scoring uses logical entailment between the discovery object's intent predicates and the anchor's neighborhood predicates. In a third embodiment, neighborhoods are hybrid: a symbolic core for governance and operation classification combined with an embedded surface for similarity-based exploration.

Connectivity manifests admit further variation. A first variant publishes only direct neighbors; a second publishes neighbors within a bounded hop radius, allowing the discovery object to plan multi-step traversals from a single retrieval; a third publishes neighbor summaries weighted by historical traversal frequency, allowing high-utility paths to be surfaced even when they are not nearest in the structural graph. Republication may be event-driven, time-driven, or hybrid, and the discovery object's reconciliation behavior may be strict (abort on stale) or permissive (re-evaluate and proceed).

Composition with Credentialed Traversal

Semantic neighborhoods compose with the credentialed traversal layer of the Cognition architecture in a strict, non-bypassable order. The neighborhood publication establishes the governance specification; the discovery object's credentials are evaluated against that specification before any semantic scoring is given decision authority; semantic alignment is consulted only among the admissible subset. This ordering means that semantic relevance cannot promote a discovery object past a governance boundary it does not satisfy. The neighborhood publication is, in effect, both an advertisement and a gate: it tells visitors what the anchor offers and what they must present to receive it.

Composition with the lineage system records every traversal as a tuple of (visiting object identity, source anchor, target anchor, neighborhood description hash, credentials presented, scoring outcome, admission decision). Auditors can later replay any discovery path against the historical neighborhood publications to confirm that each step was admissible at the time it occurred. The neighborhood description hash is the canonical reference; because publications are signed and timestamped, the lineage is reproducible without requiring the live anchor state. Composition with the depth profile mechanism allows a single anchor to expose different neighborhoods to different credential classes, so that a privileged visitor sees an enriched neighborhood description while an unprivileged visitor sees only the public projection.

Composition with the broader Cognition discovery infrastructure further constrains how neighborhoods are consumed. A discovery session is itself a governed object that aggregates the lineage of its constituent traversals; sessions admit only those traversal candidates whose neighborhood credentials are compatible with the session's overall governance scope, even when a particular discovery object holds individually sufficient credentials. This protects against scope creep within a session, where a sequence of individually admissible steps might otherwise compose into an aggregate trajectory that no single anchor would have authorized. The neighborhood description, in this composite view, is the contract between an anchor and the session: a declaration of what the anchor will admit, what it will surface, and what it will record, evaluated not only at the moment of traversal but in the context of the session's accumulated governance state.

Prior-Art Distinction

Hyperlink-based web navigation publishes anchor descriptions in the form of titles, snippets, and link text, but these descriptions are advisory only and carry no admissibility semantics. Vector search systems publish embeddings that support similarity ranking but do not gate access on governance credentials. Federated knowledge graphs publish schemas and predicates but typically lack the explicit traversal-time admissibility evaluation. The disclosed mechanism differs in three respects: the neighborhood description is a first-class governed object with its own publication lineage; admissibility is non-tradable with relevance; and the traversal record composes into a reproducible discovery lineage. None of the surveyed prior systems combine these properties.

Capability-based access systems associate credentials with operations but do not pair credentials with semantic descriptions of the resources to be operated on, leaving discovery to occur outside the capability framework. Robots-exclusion-style protocols publish access advisories but do not enforce them at the resource boundary. Policy-decision-point architectures separate policy evaluation from resource description and rely on a coordinating component to reconcile the two; the disclosed architecture instead binds description and policy into a single signed neighborhood object, eliminating the reconciliation step and the class of failures it introduces. The neighborhood publication thus occupies a position not previously realized: an advertisement that is simultaneously a contract, evaluated by visitors before commitment and enforced by anchors at admission.

Disclosure Scope

This disclosure covers the publication of structured semantic neighborhood descriptions by anchors in an adaptive index, the credentialed traversal protocol that consumes those descriptions, the scoring and admissibility composition rules, the republication and reconciliation behaviors, and the lineage recording of traversal decisions. The disclosure extends to any embodiment in which a discovery agent evaluates a published, governance-bearing neighborhood description before committing to a traversal step, regardless of whether the description is symbolic, embedded, or hybrid, and regardless of the specific scoring function employed, provided that governance admissibility is evaluated as a non-tradable gate before semantic relevance is given decision authority over the traversal outcome.
