The Event Stream Is the Agent Runtime's HTTP
The durable abstraction seam for multi-agent runtimes is the event protocol, not the tool API or the storage layer; teams that push virtualization only to tool and storage boundaries will still rebuild agent logic every time their session mechanics change.
AngleArchitecture argument that traces the abstraction boundary from tools and storage down to events, and shows what a stable event contract buys in portability and what an event schema costs in maintenance.

Once a coordinator can self-reference, replicate itself, spawn sub-sessions as tool calls, and trigger grader retries, the meaningful design artifact stops being the role diagram and becomes the budget and termination graph; architectures that look clean on paper can be sub-linear in value and exponential in cost.
AngleTreat orchestration primitives (dispatch, self-spawn, retry) as cost multipliers and argue for depth limits, budget caps, and recursion accounting as first-class review artifacts.
Source video ↗Verification Is a Role, Not an Instruction
Telling a producer agent to double-check itself is not a quality control stage; rubric contracts evaluated by a separate grading agent with a retry path are, and the worth of that stage hinges entirely on grader independence from the producer.
AngleArgue for factoring verification into a dedicated agent with an explicit pass/fail contract, then interrogate the failure mode where grader and worker share model, context, or memory.

Sharing a memory store across sessions is easy and dangerous; the valued engineering work moves to what may be written, under whose provenance, and how bad facts are invalidated once they are shared.
AngleContrast per-session isolation with desk-level sharing and specify the provenance, confidence, and invalidation controls a shared store needs before it compounds anything.
