	Cerebro - Mythic+ Module
	
	PURPOSE:
	Tracks Mythic+ dungeon completions and awards Readiness EP based on keystone level
	and guild group composition. This module provides an alternative EP source outside
	of raid progression, subject to weekly caps enforced by the EPGP module.
	
	RESPONSIBILITIES:
	1. Challenge Mode Detection - Listen for M+ start/complete events
	2. Group Snapshotting - Capture party composition and guild member count
	3. EP Calculation - Award based on level and guild participation
	4. Weekly Cap Delegation - Defer to EPGP:AwardReadinessEP for cap enforcement
	5. Run History - Archive completed runs for analytics
	
	CONTRACTS (Code-Derived + Behavior Change):
	
	# CHALLENGE_MODE_START Event Handler
	  - Snapshots party composition via UnitExists("player"/"party1-4")
	  - Counts guild members (UnitIsInMyGuild check)
	  - Stores activeRun state with startTime, level, group, guildCount
	  
	# CHALLENGE_MODE_COMPLETED Event Handler
	  - Validates activeRun exists
	  - Generates unique run ID: "mplus_" + timestamp
	  - Uses completionInfo.time (server-authoritative) for duration
	  - Archives to db.global.mplusRuns
	  - Calculates and awards EP to all guild members in group
	  - Clears activeRun state
	  
	# CalculateEPAward(level, guildCount) -> totalEP, baseEP, levelEP, bonusEP
	  - Formula: (Base + EffectiveLevelBonus * PerLevel) + (GuildBonus * min(max(0, GuildCount - 1), 4))
	  - EffectiveLevelBonus = min(max(0, level - 2), MaxLevel) -- Level scaling starts at +3
	  - GuildCount is total guild members including player; player is EXCLUDED from bonus calculation
	  - No penalty for untimed runs (onTime not used in calculation)
	  - Returns: Total EP, Base EP, Level Bonus EP, Guild Bonus EP (for breakdown display)
	  
	AWARD FORMULA (Behavior Change Applied):
	```
	TotalEP = (Base + min(max(0, Level - 2), MaxLevel) * PerLevel) + (GuildBonus * min(max(0, GuildCount - 1), 4))
	```
	
	Example (defaults: Base=20, PerLevel=5, MaxLevel=10, GuildBonus=10):
	- Solo (+2 key, 1 guildie/player only): 20 + (0*5) + (10*0) = 20 EP
	- Trio (+2 key, 3 guildies total): 20 + (0*5) + (10*2) = 40 EP
	- Trio (+3 key, 3 guildies total): 20 + (1*5) + (10*2) = 45 EP
	- Full guild (+10 key, 5 guildies): 20 + (8*5) + (10*4) = 100 EP
	
	INVARIANTS:
	1. Run IDs must be unique (enforced via timestamp-based generation)
	2. Guild count is capped at 4 for bonus calculation
	3. Keystone level is capped at MaxLevel for EP calculation
	4. Timed and untimed runs award identical EP (no penalty)
	5. Awards delegated to EPGP:AwardReadinessEP (weekly cap enforcement)
	
	DESIGN DECISIONS:
	- Guild bonus scales 0-4 (removed hard gate that required >= 4 members)
	- No untimed penalty (previous 50% penalty removed per behavior change)
	- Weekly cap handled by EPGP module (readinessCap config)
	- Run history preserved for analytics (not used for idempotency)
	
	SECURITY MODEL:
	This module does not enforce authorization for EP awards. It trusts that
	the WoW client event system is authoritative (CHALLENGE_MODE_COMPLETED only
	fires for actual completions). Configuration changes (mplusBase, etc.) are
	protected by officer checks in UI/Config.lua.
	
	EXTERNAL DEPENDENCIES:
	- Modules/EPGP.lua (AwardReadinessEP for weekly cap enforcement)
	- Database.lua (config.epgp.mplus* settings)
	- Utilities.lua (GetFullPlayerName)
	- WoW API: C_ChallengeMode, UnitExists, UnitName, UnitClass, UnitIsInMyGuild
	
	TEST COVERAGE:
	- TEST-MPLUS-001: Run state management, ID generation
	- TEST-MPLUS-002: EP calculation with level/guild scaling
	- TEST-MPLUS-003: Guild count gating and bonus scaling
