Capability Genealogy Tracking

Mechanism

Capability genealogy tracking is the mechanism by which the system maintains, for each execution substrate, a historical record of how that substrate's capability envelope has changed over time. The capability envelope is the structured description of a substrate's present structural affordances along its defined dimensions: compute class, memory architecture, model access, locality, execution guarantees, and sensor and actuator interfaces. Because the envelope is a living object that is updated whenever hardware is provisioned or deprovisioned, models are loaded or unloaded, network conditions change, or other agents consume or release shared resources, its value at any single moment is only a snapshot. The capability genealogy is the accumulated history of those snapshots: a per-substrate record of when capabilities were added, removed, or modified, and how long each configuration persisted.

The genealogy is not a derivation tree relating capabilities to one another, and it does not compute inheritance between capabilities. It is a temporal record about a single substrate: the sequence of capability-envelope changes that substrate has undergone. Each entry captures a change to the envelope together with the event that triggered it and the duration of the configuration that preceded the change.

What Each Genealogy Records

For a given substrate, the capability genealogy captures three classes of information. First, it captures the capability changes themselves: which dimensions of the capability envelope were added, removed, or modified at each point in time. Second, it captures the triggering event for each change, drawn from the operational events that alter a substrate's affordances: hardware provisioning, model deployment, resource exhaustion, maintenance, and failure. Third, it captures the duration for which each capability configuration persisted, so that the record describes not only that a configuration existed but for how long it held before the next change.

Taken together, these three classes let the genealogy answer, for any past moment, what the substrate's capability envelope was at that moment and why it subsequently changed. This is the property that makes the record useful to the routing, forecasting, and audit subsystems that consult it.

Trend Analysis for Predictive Planning

The first function the genealogy enables is trend analysis for predictive capability planning. By examining the historical pattern of a substrate's capability changes, the system forecasts future capability changes. The temporal executability forecasting subsystem projects each dimension of a substrate's capability envelope forward in time based on known scheduled events, observed trends, and declared constraints; the capability genealogy supplies the observed-trend component of that projection by recording how the substrate's dimensions have actually evolved. A substrate whose history shows a recurring pattern of capability change provides the basis for projecting when comparable changes are likely to recur.

Anomaly Detection

The second function is anomaly detection. Because the genealogy records both the capability change and the event that triggered it, the system can flag capability changes that occur without a corresponding event. The disclosure gives the example of a substrate losing a capability without a corresponding scheduled event: such an unexplained change is flagged for investigation. The genealogy thus provides a reference against which current substrate behavior can be checked, distinguishing expected capability transitions, which are tied to known triggering events, from unexpected ones that warrant scrutiny.

Forensic Analysis of Execution Failures

The third function is forensic analysis of capability-related execution failures. When an objective dispatched to a substrate fails, the genealogy reveals whether the substrate's capability was adequate at the time the objective was dispatched and, if not, when and why the capability changed. This is the same concern that the system's broader robustness mechanisms address when they detect misreported capability or partial failure: the genealogy provides the historical evidence needed to reconstruct, after the fact, whether a substrate's advertised affordances actually matched its behavior at the moment of dispatch, and to locate the change event that introduced any discrepancy.

Storage and Integrity

The capability genealogy is stored as a structured append-only log. It is subject to the same cryptographic integrity protections that apply to the agent's lineage, so that historical capability records cannot be retroactively altered. Because the log is append-only, capability configurations are never overwritten or deleted; each change is recorded as a new entry, preserving the complete history. The integrity protection ensures that the record relied upon for trend analysis, anomaly detection, and forensic analysis is itself trustworthy, and that a substrate's past capability state cannot be rewritten to conceal an unexplained change or to misrepresent the conditions under which a prior objective was dispatched.

Relation to Capability Determination

Capability genealogy tracking sits alongside the capability-determination pipeline rather than inside it. The capability determination evaluates, at the moment an objective is presented, whether an executable form of the objective can exist on a candidate substrate, producing a structured capability determination record that is persisted in the agent's lineage. The genealogy is the complementary historical view: where the determination record describes a single evaluation event, the genealogy describes the substrate's capability envelope as it has evolved across many such events. The determination consults the present envelope; the genealogy preserves the sequence of past envelopes and the events that produced them. This separation lets the system make present routing decisions from current capability state while retaining the historical record needed to forecast, detect anomalies in, and audit that state over time.

Disclosure Scope

Capability genealogy tracking, comprising the per-substrate historical record of capability-envelope changes over time, the recording of each capability addition, removal, or modification together with its triggering event and the duration of each configuration, and the three functions the record enables, trend analysis for predictive capability planning, anomaly detection of capability changes lacking a corresponding event, and forensic analysis of capability-related execution failures, together with storage of the record as a structured append-only log subject to the same cryptographic integrity protections that apply to the agent's lineage, is disclosed in the cognition filing (U.S. Application No. 19/647,395 and its international counterpart). This article describes that disclosed mechanism. The scope extends to the triggering-event classes enumerated, including hardware provisioning, model deployment, resource exhaustion, maintenance, and failure, and to deployments in which the genealogy supplies the observed-trend basis for temporal executability forecasting, provided the record remains a per-substrate, append-only history of capability-envelope change.
