Interaction

Intervene mid-simulation with Director Mode breaking news, counterfactual branching, persona DMs, and lineage diffs.

Open-source engine only

Live mid-run interventions apply when self-hosting MiroShark. Hosted /sim and x402 runs execute deterministically from the initial seed.

Mid-run controls

  • Director Mode (#interaction-director-mode): Inject breaking news into the active timeline. Agents observe the event on the next round, shifting beliefs and market prices in place.
  • Counterfactual Branching (#interaction-counterfactual-branching): Fork any historical round with a counterfactual event. Parent and child branches run independently and can be diffed side by side.
  • Persona Chat (#interaction-persona-chat): DM any individual agent or message a cohort; agents answer in character from their current belief state and post history.
  • Lineage Navigator (#interaction-lineage-navigator): Tracks parent, sibling, and split-round relationships across the counterfactual tree.

Simulation Engine

How Twitter, Reddit, and a Polymarket prediction market run in lockstep with belief updates and sliding-window memory.

Reports

How the ReACT report agent synthesizes post-mortems, consensus signals, belief trajectory SVGs, and run cost breakdowns.
