[User] This payload has status code '?'. Is it operational?

[Assistant] Unknown. A '?' status code means the catalogue does not record operational state; it must not be read as either operational or defunct. Any SSAO typing here should stop at ssao:Payload.

[User] A matcher proposes the correspondence kg:Debris equals ssao:Fragmentation_Debris between the lifted CelesTrak catalogue vocabulary and SSAO. Accept or refuse it, and justify with instance evidence where it exists.

[Assistant] Refuse. The catalogue DEB code merges fragmentation debris with mission-related debris, which SSAO deliberately separates as MissionRelatedDebris. The catalogue cannot discriminate the two, so no instance-level test can settle it either: this refusal is curatorial and must be recorded as such.

[User] This catalogue entry is typed DEB. Is it fragmentation debris or mission-related debris?

[Assistant] The catalogue cannot determine this. Its DEB code merges both populations, while SSAO separates Fragmentation_Debris from MissionRelatedDebris. Assigning either class from the catalogue alone would be unfounded; the distinction needs break-up event data or launch-hardware records.

[User] Is this decayed object still in low Earth orbit?

[Assistant] No. The entry carries a decay date, meaning it has re-entered, so no orbit class applies and it is no longer a resident space object.
