Agent pattern lineage

Engineering ancestors of Agent design patterns.

Agent patterns look new because the model is new. Architecturally, many of them inherit older software ideas: caches, queues, pipes, workflow engines, event logs, RBAC, sagas, bulkheads, observability and MapReduce. Hover over a pattern to see the bridge.

Pattern → engineering ancestor → original engineering problem

The two LSEG workshop tables are merged here into one lookup sheet. Start with the table when you need orientation; use the hover cards below when you want the design intuition.

This is the larger vocabulary behind the hover cards. The point is not to claim one-to-one inheritance. The point is to help an Agent architect ask: which old engineering problem is this new Agent problem secretly replaying?
