    - Tier 2 (advanced): 0.8-1.8 casts/hr (slower, more powerful)
    - Tier 3 (master): 0.5-0.75 casts/hr (slow but devastating)
    - Tier 4 (legendary): 0.4-0.5 casts/hr (very slow, extremely powerful)
  - Added `castProgress` to GameState (tracks progress to next cast, 0-1)
  - Updated combat tick logic:
    - Accumulates cast progress based on spell cast speed and attack speed bonuses
    - When progress >= 1, triggers a spell cast (deducts mana, applies damage)

### Work Summary
**Created Audit Report:** `AUDIT_REPORT.md`

**Key Findings:**

1. **Special Effects Implementation Status:**
   - 32 special effects defined in SPECIAL_EFFECTS constant
   - Only 2 fully implemented (OVERPOWER, BERSERKER)
   - 6 partially implemented (functions exist but not called)
   - 24 not implemented at all

2. **Critical Issue - Dynamic Functions Not Called:**
   - `computeDynamicRegen()` in upgrade-effects.ts exists but is NOT called from store.ts
   - `computeDynamicDamage()` in upgrade-effects.ts exists but is NOT called from store.ts
   - These functions implement Mana Cascade, Mana Torrent, Desperate Wells, Steady Stream, Battle Fury

3. **Enchantment Special Effects:**
   - Spell, bonus, and multiplier effects are properly applied
   - Special effects (spellEcho10, lifesteal5) are tracked in Set but never used in combat logic

4. **Missing Combat Effects:**
   - BATTLE_FURY: Requires consecutiveHits tracking (not in GameState)
   - COMBO_MASTER: Requires hit counter
   - ADRENALINE_RUSH: Should restore 5% mana on kill
   - ARMOR_PIERCE: Floor defense not implemented

5. **Missing Study Effects:**
   - MENTAL_CLARITY: +10% speed when mana > 75%
   - STUDY_RUSH: First hour 2x speed
   - STUDY_REFUND: 25% mana back on completion
   - KNOWLEDGE_ECHO: 10% instant study chance

6. **Missing Loop Effects:**
   - MANA_ECHO: 10% double click mana - not in gatherMana()
   - EMERGENCY_RESERVE: Keep 10% mana on new loop - not in startNewLoop()

7. **Balance Concerns Identified:**
   - manaThreshold upgrade is net negative early game
   - scrollCrafting skill exists but scroll system not implemented
   - fieldRepair skill exists but repair system not implemented
   - Research skills unlock effects that don't work

8. **200+ Special Effects in skill-evolution.ts:**
   - Across 5 tiers of evolution paths
   - Most tier 2-5 effects are not implemented
   - Victory conditions defined but not coded

**Files Analyzed:**
- `src/lib/game/upgrade-effects.ts` - SPECIAL_EFFECTS constant and dynamic functions
- `src/lib/game/data/enchantment-effects.ts` - Enchantment effect definitions
- `src/lib/game/constants.ts` - SKILLS_DEF and skill effects
- `src/lib/game/skill-evolution.ts` - 200+ special effect definitions across tiers
- `src/lib/game/store.ts` - Game tick and action logic
- `src/lib/game/computed-stats.ts` - Computed stat functions
- `src/lib/game/effects.ts` - Unified effects system

**Recommendations Provided:**
- Priority 1: Call dynamic regen/damage functions, implement core effects
- Priority 2: Add hit tracking state, implement combat specials
- Priority 3: Implement study-related effects
- Priority 4: Implement or remove unused skills (scrollCrafting, fieldRepair)

Task ID: 1
Agent: Main
Task: Fix study system and game time freeze issues

Work Log:
- **Fixed git credentials**: Saved credentials to AGENTS.md file for persistence
- **Fixed study system**: Changed from upfront mana cost to per-hour deduction
  - Updated StudyTarget type to include `manaCostPerHour` and `totalCost`
  - Updated study-slice.ts to calculate per-hour cost without deducting upfront
  - Updated store.ts tick function to deduct mana each tick during study
  - Added check for insufficient mana - pauses study and saves progress
- **Fixed game time freeze bug**: `newTotalTicks` was referenced before being defined
  - Moved `newTotalTicks` calculation to before study section
  - Removed duplicate declaration in combat section
- **Fixed mobile UI issues**:
  - Fixed CalendarDisplay component props (was using `currentDay` but passed `day`)
  - Added proper grid layout to calendar for mobile (7 columns) and desktop (14 columns)
  - Fixed tabs layout from `grid-cols-8` to `flex flex-wrap` for mobile responsiveness
  - Made tab triggers smaller on mobile with `text-xs px-2 py-1`
- **Added `lastStudyCost` tracking** for STUDY_REFUND special effect

Stage Summary:
- Study now costs mana per hour instead of all upfront

Task ID: 2
Agent: Main
Task: Comprehensive codebase audit and bug fixes

Work Log:
- **Fixed Critical Syntax Errors**:
  - Missing `[` brackets in `startCraftingEquipment` and `deleteMaterial` in store.ts
  - Same syntax errors in crafting-slice.ts
  - These were causing runtime failures in crafting and material deletion
- **Fixed State Mutation Issues**:
  - Deep cloned `lootInventory` before mutation in tick function
  - Created new objects for `materials`, `essence`, and `blueprints` to prevent state mutation
- **Fixed Race Condition**:
  - Removed mid-tick `set()` call that could cause inconsistent state
  - All state updates now happen in the final `set()` call
- **Fixed Logic Errors**:
  - COMBO_MASTER now uses `totalSpellsCast` instead of `totalTicks` for accurate hit counting
  - `deductSpellCost()` now clamps mana to 0 to prevent negative values
  - `hasSpecial()` now handles undefined/null specials gracefully
- **Set Up Test Framework**:
  - Installed Vitest testing framework
  - Created vitest.config.ts
  - Added 36 tests for computed-stats and upgrade-effects
  - All tests passing

Stage Summary:
- 6 critical bugs fixed
- Test framework established with 36 passing tests
- Code quality improved with null safety checks
- All changes committed and pushed to Gitea

2. `FLOW_SURGE` - Clicks restore 2x regen for 1 hour
3. `MANA_EQUILIBRIUM` - Overflow regen converts to insight
4. `PERFECT_MEMORY` - Never lose study progress on cancel
5. `QUICK_MASTERY` - -20% study time for final 3 levels
6. `PARALLEL_STUDY` - Study 2 things at 50% speed each

- **Fixed Quick Conversion** - Mana conversion is not available to players (no UI button)
  - Replaced with `Elemental Affinity`: Newly unlocked elements start with 10 capacity
- **Fixed Mana Ascension** - "Extra max mana when above 90% mana" didn't make sense
  - Replaced with `Mana Conduit`: Meditation also regenerates 5% max elemental mana per hour
- **Removed all conversion-related upgrades**:
  - `Flow Conversion` (mf_t1_l5) → Replaced with `Mana Overflow`: Raw mana can exceed max by 20%
  - `Efficient Conversion` (ea_t1_l5) → Replaced with `Elemental Surge`: +15% elemental damage
- **Fixed duplicate IDs**:
  - Fixed `ea_t1_l5_expand2` used twice → Renamed second one to `ea_t1_l5_surge`
  - Fixed `ea_t1_l10_surge` duplicate → Renamed to `ea_t1_l10_power`
- **Updated SPECIAL_EFFECTS constant**:
