Topology #9 — independent_analysis → iterate(critique, until: ...) → chair.

Members analyse independently, then critique each other's outputs iteratively until a convergence callback returns true or max_iterations is reached. The chair synthesizes the final iteration's outputs.

Options

• :members — list of {id, module, opts} tuples (required)
• :chair — {module, opts} tuple (required)

• :until — (prev_round_result | nil, current_round_result -> boolean) (default: always false)

• :max_iterations — positive integer, default 3
• :as — module name for the created council module (optional)

Usage (module-form)

council =
  CouncilEx.Councils.Consensus.new(
    as: MyApp.ConsensusCouncil,
    members: [
      {:m1, MyApp.Members.Analyst, [provider: :openai, model: "gpt-4o-mini"]},
      {:m2, MyApp.Members.Analyst, [provider: :openai, model: "gpt-4o-mini"]}
    ],
    chair: {MyApp.Members.Synth, [provider: :openai, model: "gpt-4o"]},
    max_iterations: 3
  )

Usage (dynamic / data-only form)

new_dynamic/1 returns a %CouncilEx.DynamicCouncil{} with the same topology. The :until callback (when provided) MUST be a remote function capture — &MyMod.converged?/2 — not an inline fn, because dynamic councils are designed to be JSON-serializable. Inline fn works at runtime but won't survive to_json/from_json. Omit :until to rely solely on :max_iterations.
