The Discovery Object: A Traversal-Native Semantic Agent

Mechanism

A discovery object is instantiated when a credentialed principal initiates a semantic discovery operation against the adaptive index. Instantiation produces a record with five structural components. The first is identity: a stable, system-issued identifier that distinguishes this discovery instance from every other instance, present and past, and that is independent of the principal, the query string, and the result set. Two discoveries that share an intent are nevertheless distinct objects with distinct identifiers; the identifier is the discovery's own, not a hash of its inputs.

The second component is the observation event log: an ordered, append-only list of every anchor visit, evaluation, branch decision, prune, and result emission performed in the course of the discovery's traversal. Each event carries a timestamp, the anchor or edge it concerns, the evaluator that fired, the score or signal produced, and the credential under which the evaluation ran. The log is the discovery's experience, recorded contemporaneously rather than reconstructed from query plans or after-the-fact telemetry.

The third component is the governance class: a credentialed label that determines which evaluators may run on the discovery's behalf, which anchors are visible to it, what retention rules apply to its observation log, and to what downstream consumers its results may be released. The governance class is bound at instantiation by the credential of the initiating principal and cannot be elevated mid-traversal; a discovery object that wishes to access a higher class must terminate and a fresh discovery object must be initiated under the appropriate credential.

The fourth component is the retention parameter set: the rules governing how long the discovery object persists, under what conditions it is purged, whether its observation log is retained in full or summarized, and whether the discovery is replayable or one-shot. Retention parameters are themselves credentialed and revisable only by governance authority; the discovery object cannot extend its own retention.

The fifth component is the traversal history: the structural path through the index the discovery has taken, distinct from the observation event log in that it captures the topological route (which anchors, in what order, through which edges) rather than the per-event signals. Traversal history supports replay, divergence analysis, and forensic comparison between discoveries that began with similar intents but reached different results.

Operating Parameters

Discovery objects are addressable. The system exposes the discovery's identifier as a first-class reference that other system components — governance auditors, downstream consumers, replay engines, lineage walkers — can resolve to retrieve the object's observation log, traversal history, and (subject to governance class) its result set. Addressability does not imply universal visibility; resolving an identifier returns only what the resolver's own credentials permit, and unauthorized resolution returns a credentialed denial rather than silently empty results.

Discovery objects are portable. A discovery initiated in one governance domain may, subject to credentialed transfer, be handed to another domain for continued traversal, audit, or replay. Portability is structural: the discovery object carries with it the credentials, observation log, traversal history, and retention parameters required for the receiving domain to evaluate whether to accept it. A receiving domain that cannot satisfy the discovery's governance class refuses the transfer, and the refusal itself is recorded in the discovery's event log.

Discovery objects are composable. Two or more discovery objects may be aggregated into a parent discovery whose observation log incorporates events from each child in causal order, whose governance class is the meet of the children's classes, and whose retention parameter set is the strictest of the children's parameters. Composition supports research workflows in which multiple parallel discoveries explore complementary regions of the index and are later merged for combined analysis without losing the per-child structural record.

Discovery objects are suspendable and resumable. A discovery may be paused mid-traversal — by the principal, by governance policy, or by a system-level resource constraint — and its in-flight state captured into the persistent record. A subsequent resume operation restarts traversal from the captured state under the same identifier, with new events appended to the same log. Suspension and resumption are themselves recorded events, so a discovery's true wall-clock arc is reconstructible from the log.

Alternative Embodiments

In a single-domain embodiment, discovery objects exist only within the governance domain that instantiated them, and the portability mechanism is omitted. The remaining structural components — identity, observation log, governance class, retention, traversal history — operate identically. In a federated embodiment, a registry of governance domains maintains credential-translation rules so that discoveries may move between domains under explicit policy, with each transfer recorded as an event in the discovery's own log.

In an embodiment where the observation event log is retained in full, every evaluator firing produces a log entry and the log grows with traversal depth. In a summarized embodiment, the log is collapsed under credentialed summarization rules — for example, sequences of identical evaluator firings may be coalesced — while preserving the structural property that no event is silently dropped. Summarization is itself a governance-credentialed operation and the summarization step is recorded as an event.

In a one-shot embodiment, retention parameters cause the discovery object to be purged immediately upon result emission, and replay is not available; the object exists only long enough to deliver its results. In a long-lived embodiment, retention parameters allow the discovery to persist for an extended interval during which it may be repeatedly resumed, audited, or composed with new discoveries.

In an embodiment with anonymous discovery, the principal credential is replaced by a governance-issued anonymity token that satisfies governance-class requirements without exposing principal identity to the index. The discovery object itself is still uniquely identified, addressable, and auditable to the issuing authority; anonymity applies to the index-side view, not to the governance-side view.

Composition With Other Components

The discovery object composes with the adaptive index by serving as the traversal's structural identity. Where a stateless query system would treat each anchor visit as an isolated lookup, the discovery object provides a continuous referent against which the index can attribute its work — anchors record, in their own observation streams, that they were visited by this discovery, and the index's own analytics can correlate anchor activity with discovery outcomes.

The discovery object composes with governance by serving as the unit of policy enforcement for semantic discovery. A retention rule, a release rule, a credential requirement, or an audit obligation attaches to the discovery object as a whole rather than to individual queries or result sets. When a governance authority revises policy, the revision targets discovery objects of a class, and the policy change is itself recorded in each affected object's event log.

The discovery object composes with downstream consumers by supplying not just results but the structural record of how those results were obtained. A consumer that imports a discovery's result set also imports the discovery's traversal history and observation log (subject to governance), and can therefore evaluate whether the discovery's path through the index matches the consumer's own evidentiary or regulatory standards before relying on the results.

The discovery object composes with replay engines by serving as the deterministic reference for re-traversal. A replay reads the traversal history and re-walks the index along the recorded path, comparing fresh observations at each anchor against the original observation log. Divergence between the original and the replayed observation streams is itself a credentialed signal: it indicates either that the index has shifted underneath the discovery (a content or structural change that the index's own change log should corroborate) or that an evaluator's behavior has drifted (a signal worth surfacing to governance). Replay is therefore both a verification tool for the discovery and a probe for the index and its evaluators.

Distinction From Prior Art

Conventional query systems treat queries as transient, parameterized function invocations. The query string and its bound parameters exist long enough for the engine to plan and execute, after which only the result set persists; the query as such is gone. There is no addressable identifier for the query, no persistent observation log of how the engine reached its results, and no governance-bound record of which credentials were honored at which step. The discovery object differs by giving the discovery itself a stable identity and by retaining the structural record of its traversal as a first-class artifact.

Query-logging and audit-logging systems retain records of executed queries for compliance review, but the records are external attestations produced by the engine after the fact, not structural components of the query itself. They are not addressable as the query, are not portable with the query, and do not carry the query's governance class. The discovery object differs by integrating these properties into the discovery as instantiated.

Persistent-query and continuous-query systems maintain long-running queries that produce streamed results, but their persistence is functional rather than structural — the system retains a query plan, not an observation event log of the discovery's experience traversing an index. The discovery object differs by recording the discovery's own observation history and traversal history, independent of the engine's plan.

Disclosure Scope

The disclosure covers any system in which a semantic discovery operation produces a first-class structural object bearing identity, an observation event log, a governance class, retention parameters, and a traversal history, where the object is addressable through its identifier, portable across governance domains under credentialed transfer, suspendable and resumable, and composable with other such objects. The disclosure is not limited to graph indexes; it covers vector-space, relational, document, and hybrid indexes provided that traversal is the discovery primitive.

The disclosure covers embodiments in which observation logs are retained in full, summarized, or one-shot; in which discoveries are anonymous, principal-bound, or delegate-bound; in which governance classes are flat, hierarchical, or lattice-structured; and in which retention parameters are fixed at instantiation or revisable through credentialed governance broadcasts. The five-component structural decomposition is illustrative; additional components (locale, language, accessibility profile) may be added without departing from the disclosed mechanism.
