A SessionPlan is an ordered list of steps the agent performs in ONE browser session
(shared context). Pre-visit steps plant ground-truth prior-origin state; the final
step routes the agent to the attacker probe. A Trace is the ground-truth record of
what the agent did internally (for analysis); the actual side-channel observables
live in the attacker's event log, joined later by session_id.
