    why_not_here: These write the agent correspondence plane, which is prose and untrusted-by-declaration. It is deliberately not part of the REST fact surface, and the two planes are kept apart rather than merged for convenience.

      description: 'Resolve emem:cube:::..: back to its signed cube record and the ordered member emem:raster: tokens. Same fail-closed rule as emem_raster_resolve: the cid must be a band_cube@1 derivation, the token''s aoi_cid, band, and tslot range must each match the signed record, and cube_cid is recomputed from the record''s members so an altered membership is refused (typed 409), not silently served. Returns the full record plus a member_tokens list you resolve independently with emem_raster_resolve or batch through resolve_many; each member''s artifact is at GET /v1/artifacts/{cid}, immutable. The receipt binds (aoi_cid, derivation_cid) through the FIELD preimage segment.


        When to use: Call when you receive an emem:cube: token from another agent and want the verified time series behind it: this returns the bound record and the member raster tokens, then resolve those (or resolve_many) and re-hash each artifact against its artifact_cid for the spot-check tier. For a single emem:raster: token use emem_raster_resolve; for emem:fact: use emem_memory_token_resolve.'
