learned-encounter-data.md

Real data from session reports and persisted memory files. Nektulos Forest, 233 defeats across multiple sessions. Shows session grade progression B -> A -> A, auto-tuned parameters drifting from defaults, and fight duration improving for the same mob type over time. Character name redacted.

Persisted auto-tuning (drifted from defaults)

// data/memory/nektulos_tuning.json
{ "v": 1, "roam_radius_mult": 1.2999999999999998, "social_add_limit": 5, "mana_conserve_level": 0 }

Defaults: roam_radius_mult=1.0, social_add_limit=3, mana_conserve_level=0. High defeat rate + survival triggers the relaxation path in evaluate_and_tune(): search radius expanded 30%, social pull aggression increased from 3 to 5.

Fight duration: same mob type, first session vs latest

// data/memory/nektulos.json (233 defeats, 500 sightings)
{"x":607,"y":71,"name":"a_tree_snake003","level":5,"fight_s":23.9,"_context":"first session defeat"}
{"x":694,"y":-6,"name":"a_tree_snake013","level":4,"fight_s":9.0,"_context":"latest session defeat"}

Scorecard weights (how the grade is computed)

# From brain/scorecard.py -- weighted average, each category 0-100
weights = {"defeat_rate": 25, "survival": 20, "pull_success": 15,
           "uptime": 15, "pathing": 10, "mana_efficiency": 10, "targeting": 5}
