 ### Phase 6: Effect Normalization
 
-- parse symbolic affix lines into normalized effects
-- populate `critical_effect`
-- gradually enrich prose-derived effects over time
+Phase 6 is complete for symbol-driven affixes.
+
+Phase-6 notes:
+
+- footer legends are parsed into table-specific affix metadata before effect normalization
+- symbolic affix lines are normalized into `critical_effect` rows for both base results and conditional branches
+- the normalized pass currently covers direct hits, must-parry, no-parry, stun, bleed, foe penalties, attacker bonuses, and `Mana` power-point modifiers
+- result and branch `parsed_json` payloads now store the normalized symbol effects
+- the web critical lookup now returns and renders parsed affix effects alongside the raw affix text
+- prose-derived effects remain future work
