Public lens
A public dataset or disclosure channel that records a bounded aspect of grid, market, contractual, declared, metered, geographic, or institutional activity. A lens is not the full physical system.
Definitions with boundaries
Public grid evidence lexicon
Each term names a specific observable relation. The definition includes what the term does not establish.
Public duty profile
The time-structured external footprint assembled from public accepted actions, metering, declarations, contracts, outages, registries, and context. It does not reveal internal asset state by itself.
Accepted-action cadence
The frequency, spacing, duration, direction, and switching pattern of publicly visible accepted balancing actions. It is not total cycling or a fatigue measure.
B1610 metered trace
A settlement-period public record of metered energy volume. It can establish public physical activity at its reporting grain, but cannot reveal sub-period control actions or internal battery response.
Declared capability
The maximum export or import level declared through MEL or MIL records. It records a declared operational boundary, not a direct health measurement.
Support diversity
A descriptive concentration measure derived from visible accepted BM participation, reported here as an effective number using inverse HHI. It is not electrical network redundancy.
Maturity horizon
The earliest as-of time at which a source can reasonably be compared with other sources after publication lag, revision, and settlement effects. Different lenses do not mature simultaneously.
Source correction
A change in interpretation produced when an independent lens exposes the blind spot of another. For example, metering may correct the inference that BM absence means physical inactivity.
Targeted evidence request
A specific request for owner-held records designed to resolve an observed public inconsistency or unusual role. It is a review question, not a risk conclusion.
