The agency layer
The alphabet is a network,
not a list.
RCMP. CSIS. CSE. CBSA. CAF. DND. ITAC. IRCC. The acronyms imply separate boxes; joint teams, statutory disclosures, shared systems, and coordinated operations connect them.
The distinctions still matter. Intelligence is not evidence. Border authority is not police authority. Military command is not civilian law enforcement. Foreign intelligence is not domestic policing. The research task is to preserve those differences while tracing what moves between them.

Private vendors—including cloud and platform companies—remain part of the infrastructure layer. They are suppliers and data custodians to be mapped, not what “alphabet” means in this research frame.
