Phase F: Fidelity Completion

[DeveshParagiri]

Summary

Completes Phase F fidelity tier implementation.

Bug fix:

• Fixed peer opinions fidelity gating: was hardcoded to 5, now 5/5/10 for low/medium/high

New features:

• Most impactful conversations: Ranks conversations by state change magnitude (sentiment + conviction deltas)
• Elaborations CSV export: Flattened CSV with agent demographics + outcomes for DS workflows

Changes

• extropy/simulation/engine.py - Fix peer limit, add exports
• extropy/simulation/aggregation.py - Add compute_most_impactful_conversations(), export_elaborations_csv()
• docs/capabilities.md - Document conviction self-awareness, repetition detection

Output Files

After simulation, you'll now get:

• elaborations.csv - One row per agent with demographics and all outcomes
• meta.json includes most_impactful_conversations array (top 10 by impact score)
