Computed convergence asks how much each agent's step-title list changes between consecutive rounds. It does not score the quality of its response or compare every pair of agents within a round.
| Element | Meaning |
|---|---|
| Coloured line / legendReviewed A 0.1.4 · R 0.1.16 | One series per agent slot, labelled with its ID/model and settings where shown. |
| Horizontal axisReviewed A 0.1.4 · R 0.1.16 | Refinement rounds 1 onward; there is no preceding proposal for round 0. |
| Vertical axisReviewed A 0.1.4 · R 0.1.16 | Number of changed steps, defined as added plus removed in a one-to-one title comparison with that slot's previous version. |
| Dashed meanReviewed A 0.1.4 · R 0.1.16 | Arithmetic mean of changed counts among proposals present in that round, rounded to one decimal. Missing agents are not added as zero-valued observations. |
| Point / popoverReviewed A 0.1.4 · R 0.1.16 | The round, changed count and underlying kept, added, removed and current size values. Hover/focus or click to pin. |
| Steps kept, added and removed tableReviewed A 0.1.4 · R 0.1.16 | The same per-agent/per-round figures in text, including current number of steps. |
| No proposalReviewed A 0.1.4 · R 0.1.16 | That agent has no stored proposal in that round. It is not evidence of full stability. |
Match each current step to one still-available preceding step with title similarity at least 0.6. Each preceding step can be used at most once. Then:
kept = number of matched pairs
added = unmatched current steps
removed = unmatched previous steps
changed = added + removed
size = kept + added
For a previous proposal of 20 steps and a new one of 22, suppose 18 match. The chart shows 4 added, 2 removed, 6 changed, 18 kept and size 22. A changed count can exceed the current size because removals also count.
If the same slot has no previous proposal, all its current steps count as added and none as removed. If no refinement data exists, there is no convergence series to draw.
A falling line indicates fewer title additions/removals. Zero means all titles could be paired at the threshold; descriptions, metrics and dependencies may still have changed substantially. High change can mean useful correction, superficial rewriting or deterioration.
This chart differs from the yellow converging/diverging badge, which is the analyst's view of the round. It also differs from the influence matrix's diagonal because that matrix assigns exclusive sources with an own-step preference, while convergence uses one-to-one matching only against the slot's previous version.
Use the chart to identify where to investigate diminishing returns. To claim that additional rounds no longer help, examine substantive changes and independent outcome criteria across repeated runs, alongside costs. Textual stability alone is not a stopping guarantee.
