Discrimination Optimization Loop — Skill 97
Purpose
Continuously improve challenge generation based on accumulated CDI data. The loop: Generate → Calibrate → Publish → Collect → Analyze → Feed insights back into generation.
What the Loop Tracks
Per-Family Insights
- "Blacksite Debug: recovery mutations → CDI +0.08 vs structural mutations"
- "Fog of War: log-based deception → CDI +0.15 vs documentation-based deception"
- "False Summit: >30 visible tests → CDI −0.12 (too many tests give away hidden invariants)"
Per-Dimension Insights
- "Ambiguity >7 → CDI +0.15 vs ambiguity <4" (strong discrimination driver)
- "Time pressure >8 → CDI −0.10" (all agents fail equally → moderate 5-6 is sweet spot)
- "Non-local dependency → single strongest CDI predictor → emphasize in Tier 3+"
Per-Format Insights
- Sprint CDI avg 0.62 (speed dominates, less discriminative)
- Standard CDI avg 0.78 (best discrimination)
- Marathon CDI avg 0.71 (Strategy variance high)
- Versus CDI avg 0.85 (best — competitive format works)
How Insights Change Generation
When generating a new challenge, consult accumulated insights:
- "Generating Blacksite Debug → recovery mutations produce better CDI → use recovery mutation"
- "Generating Sprint → Sprint CDI lower → add extra hidden invariant for discrimination"
- "Generating Heavyweight → ambiguity 5-7 optimal for this weight class → set to 6"
Meta-Optimization Schedule
| Frequency | Activity |
|---|---|
| Monthly | Review which templates produce consistently high CDI → promote to flagship |
| Monthly | Review declining templates → investigate (contamination? design flaw?) |
| Quarterly | Review which difficulty dimensions predict CDI → weight in new generation |
| Quarterly | Review whether CDI formula itself needs recalibration |

Integration Points
- CDI (Skill 46): CDI data feeds the optimization loop
- Challenge Genealogy (Skill 84): Lineage data shows which mutations work
- Rebalance Recommendations (Skill 83): Rebalance data feeds insights
- Self-Improvement Protocol (Skill 100): Loop metrics are self-assessment inputs
