description	Iterative convergence to a single answer through Classic Delphi, Modified Delphi, or Nominal Group Technique rounds.
dependencies	{"tactics":["iterative-convergence-round"],"sops":["consensus-synthesis"]}

Convergence Distillation

Purpose: Drive multiple independent perspectives toward a single shared answer through iterative anonymous feedback rounds. Each round narrows the distribution of judgments until consensus threshold is met or stability is reached.

When to use:

• Need a single definitive answer from diverse experts
• Establishing guidelines, thresholds, or standards
• Quantitative estimates requiring group calibration
• Situations where social pressure would bias face-to-face discussion

Budget

Parameter	Constraint
Rounds	2–4 (stop at consensus or stability)
Perspectives	≥4 independent
Consensus threshold	≥70% agreement or IQR ≤ 1

State Ledger

Key	Type	Description
question	string	The focal question being converged
perspectives	array	List of perspective descriptions
rounds	array	History of all round results
current_round	integer	Current round number
consensus_score	float	Latest consensus measurement
stability	boolean	Whether scores stopped changing

Available Tactics

• iterative-convergence-round — Core loop: collect → feedback → revise → measure → decide

Available SOPs

• judgment-collection
• feedback-distribution
• consensus-measurement
• round-decision
• consensus-synthesis

Execution Guidance

1. Frame the question clearly with response format (Likert, numeric, ranking)
2. Run iterative-convergence-round until round-decision returns "stop"
3. If max rounds reached without consensus, document dissent
4. Run consensus-synthesis to produce final report

Output Format

consensus_reached: true/false
final_answer: <aggregated result>
consensus_score: <float>
rounds_completed: <int>
dissent_record: <items that did not converge>

Available Tactics

Optional, no fixed order; the final leaf is always a sop.

Tactic	When to use
iterative-convergence-round	Execute one full Delphi round — collect judgments, distribute anonymous feedback, measure consensus, decide whether to continue.

Available SOPs

Optional, no fixed order; the final leaf is always a sop.

SOP	When to use
consensus-synthesis	Synthesize all rounds into a final consensus report documenting agreements, dissent, and process.
