Ticket 102 (splitting the engine into reader/primary/profile actors)
was a single multi-thousand-line ticket covering a new actor
topology, an EngineHandle API redesign, a query fan-out layer, moving
alerts, and a full test-harness rewrite, with some design decisions
deliberately left open. Splitting it into six sequenced tickets
(profile actor skeleton + signaling, move metric computation, move
alert evaluation, split the handle API, query fan-out, test harness
rework) lets each land as its own reviewable commit instead of one
large speculative rewrite.
