+# Task 11: Fix Spell Info Display - Context Summary
+
+## Task Status
+**Partially done** - dmg/cast is shown correctly, total DPS is shown, but per-spell DPS display is incorrect.
+
+## Files Analyzed
+
+### 1. `/home/user/repos/Mana-Loop/src/components/game/tabs/SpireTab.tsx`
+- **Lines 356-360**: Spell info display for active equipment spells
+  - Shows: `⚔️ {fmt(calcDamage(store, spellId))} dmg/cast`
+  - Shows: `⚡ {fmt(Math.floor(calcDamage(store, spellId) * (spellDef.castSpeed || 1)))} dmg/hr`
+  - **ISSUE**: The "dmg/hr" calculation is incorrect. It multiplies damage by `castSpeed` (which is casts/hour), but doesn't account for:
+    1. `quickCast` skill bonus (`1 + (skills.quickCast || 0) * 0.05`)
+    2. Equipment `attackSpeedMultiplier` from upgrade effects
+    3. The actual conversion from casts/hour to DPS
+
+### 2. `/home/user/repos/Mana-Loop/src/lib/game/constants/spells.ts`
+- **Spell Definition Structure** (`SpellDef` interface in `/src/lib/game/types/spells.ts`):
+  - `castSpeed?: number` - **Casts per hour** (default 1, higher = faster)
+  - `dmg: number` - Base damage per cast
+  - Examples: `manaBolt` has `castSpeed: 3` (3 casts per hour), `fireball` has `castSpeed: 2`
+
+### 3. `/home/user/repos/Mana-Loop/src/lib/game/utils/combat-utils.ts`
+- **`calcDamage(state, spellId, floorElem)`** (lines 84-131):
+  - Calculates damage per cast
+  - Factors: `baseDmg = sp.dmg + (skills.combatTrain || 0) * 5`
+  - Multipliers: `arcaneFury`, `elementalMastery`, `guardianBane`, `rawDamage`, `elemDamage`
+  - Elemental bonus: `getElementalBonus(sp.elem, floorElem)`
+  - Crit: `precision` skill + boon critChance
+
+- **`getTotalDPS(state, upgradeEffects, floorElem)`** (lines 265-300):
+  - Calculates TRUE total DPS from all active equipment spells
+  - Uses `baseCastTime` (not `castSpeed`) - **BUG**: `baseCastTime` is not defined in `SpellDef`!
+  - Actual formula used:
+    ```typescript
+    const baseCastTime = spellDef.baseCastTime || 1.0;
+    const castingSpeedBonus = 1 + (state.skills.castingSpeed || 0) * 0.1;
+    const equipmentAttackSpeed = upgradeEffects.attackSpeedMultiplier || 1;
+    const castTime = baseCastTime / (castingSpeedBonus * equipmentAttackSpeed);
+    const spellDPS = damage / castTime;
+    ```
+  - **ISSUE**: `baseCastTime` is always 1.0 (fallback), so the formula doesn't use `castSpeed` at all!
+
+### 4. `/home/user/repos/Mana-Loop/src/lib/game/hooks/useGameDerived.ts`
+- **DPS calculation for active spell** (lines 145-152):
+  ```typescript
+  const spellCastSpeed = activeSpellDef.castSpeed || 1;  // casts per hour
+  const quickCastBonus = 1 + (store.skills.quickCast || 0) * 0.05;
+  const attackSpeedMult = upgradeEffects.attackSpeedMultiplier;
+  const totalCastSpeed = spellCastSpeed * quickCastBonus * attackSpeedMult;
+  const damagePerCast = calcDamage(store, store.activeSpell, floorElem);
+  const castsPerSecond = totalCastSpeed * HOURS_PER_TICK / (TICK_MS / 1000);
+  return damagePerCast * castsPerSecond;
+  ```
+  - **This is the CORRECT formula for DPS**:
+    - `castsPerSecond = castSpeed * quickCastBonus * attackSpeedMult * (HOURS_PER_TICK / (TICK_MS / 1000))`
+    - With `HOURS_PER_TICK = 0.04` and `TICK_MS = 200`:
+    - `castsPerSecond = castSpeed * quickCastBonus * attackSpeedMult * 0.04 / 0.2 = castSpeed * quickCastBonus * attackSpeedMult * 0.2`
+
+### 5. `/home/user/repos/Mana-Loop/src/lib/game/store/combatSlice.ts`
+- **`processCombat`** (lines 60-75): Actual combat uses `castSpeed` correctly:
+  ```typescript
+  const baseAttackSpeed = 1 + (state.skills.quickCast || 0) * 0.05;
+  const totalAttackSpeed = baseAttackSpeed * effects.attackSpeedMultiplier;
+  const spellCastSpeed = spellDef.castSpeed || 1;
+  const progressPerTick = deltaHours * spellCastSpeed * totalAttackSpeed;
+  ```
+  - Note: Uses `quickCast` skill (not `castingSpeed` which is from boons)
+
+## Summary of Issues
+
+### Issue 1: Per-spell "dmg/hr" display is wrong in SpireTab.tsx
+- **Current**: `calcDamage(store, spellId) * (spellDef.castSpeed || 1)` 
+- **Problem**: This just multiplies damage by casts/hour, but doesn't convert to actual DPS correctly
+- **Correct formula** (from `useGameDerived.ts`):
+  - `dps = damagePerCast * castSpeed * quickCastBonus * attackSpeedMult * HOURS_PER_TICK / (TICK_MS / 1000)`
+  - Or simpler: `dps = damagePerCast * castSpeed * 0.2` (when no bonuses)
+
+### Issue 2: `getTotalDPS` uses wrong field
+- **Current**: Uses `baseCastTime` which doesn't exist in `SpellDef`
+- **Fix needed**: Should use `castSpeed` (casts per hour) and convert to DPS properly
+- **Correct formula**:
+  ```typescript
+  const castsPerHour = spellDef.castSpeed || 1;
+  const quickCastBonus = 1 + (state.skills.quickCast || 0) * 0.05;
+  const attackSpeedMult = upgradeEffects.attackSpeedMultiplier || 1;
+  const totalCastsPerHour = castsPerHour * quickCastBonus * attackSpeedMult;
+  const spellDPS = damage * totalCastsPerHour / 3600; // Convert casts/hour to casts/second
+  ```
+
+### Issue 3: Inconsistent skill usage
+- `combatSlice.ts` and `useGameDerived.ts` use `quickCast` skill for cast speed bonus
+- `getTotalDPS` uses `castingSpeed` (which is from boons, not player skills)
+- Need to verify which is correct or use both
+
+## Correct Formulas
+
+### True DPS for a spell:
+```
+DPS = damage_per_cast × (castSpeed × quickCast_bonus × attackSpeed_multiplier) / 3600
+```
+
+Where:
+- `damage_per_cast` = `calcDamage(store, spellId, floorElem)`
+- `castSpeed` = `spellDef.castSpeed || 1` (casts per hour)
+- `quickCast_bonus` = `1 + (skills.quickCast || 0) * 0.05`
+- `attackSpeed_multiplier` = from equipment effects
+- Divide by 3600 to convert from casts/hour to casts/second
+
+### For display in SpireTab.tsx per-spell:
+- **dmg/cast**: Already correct - uses `calcDamage(store, spellId)`
+- **DPS**: Should show `damage_per_cast × (castSpeed × quickCast × attackSpeed) / 3600`
+- Current "dmg/hr" is misleading - it's not actually damage per hour with bonuses
+
+## Files to Modify
+1. `/home/user/repos/Mana-Loop/src/components/game/tabs/SpireTab.tsx` (lines 356-360) - Fix per-spell DPS display
+2. `/home/user/repos/Mana-Loop/src/lib/game/utils/combat-utils.ts` (lines 280-295) - Fix `getTotalDPS` to use `castSpeed` instead of `baseCastTime`

+# Task 14: Fix AchievementsTab Nesting - Context Summary
+
+## Current State (Problem)
+
+### Redundant Nested Layers Found:
+
+1. **Nested GameCards (Double Card Wrapper)**
+   - `AchievementsTab.tsx` wraps everything in a `<GameCard>` (lines 16-42)
+   - `AchievementsDisplay.tsx` ALSO wraps everything in a `<GameCard variant="default" className="w-full">` (line 63)
+   - This creates nested cards - a card inside a card - which is redundant and causes visual/structural issues
+
+2. **Duplicate Headings**
+   - `AchievementsTab.tsx` has an `<h2>` heading "Achievements" with badge showing `{unlockedCount} unlocked` (lines 19-26)
+   - `AchievementsDisplay.tsx` has an `<h3>` heading "Achievements" with badge showing `{unlockedCount} / {totalCount}` (lines 64-72)
+   - Both components render their own heading - this is redundant
+
+### File Analysis:
+
+#### AchievementsTab.tsx Structure:
+```
+<div className="space-y-4">
+  <GameCard>                    ← OUTER CARD (should be removed)
+    <h2>Achievements</h2>       ← OUTER HEADING (should be removed)
+    <AchievementsDisplay />      ← This component brings its own Card + Heading
+  </GameCard>
+</div>
+```
+
+#### AchievementsDisplay.tsx Structure:
+```
+<GameCard variant="default">     ← INNER CARD (should stay)
+  <h3>Achievements</h3>          ← INNER HEADING (should stay)
+  <ScrollArea>
+    {/* achievement categories */}
+  </ScrollArea>
+</GameCard>
+```
+
+## Correct Structure (After Fix)
+
+The `AchievementsTab` should NOT wrap `AchievementsDisplay` in a GameCard or provide its own heading. The correct structure is:
+
+### AchievementsTab.tsx (Fixed):
+```
+<div className="space-y-4">
+  <AchievementsDisplay />    ← Only render the display component, no wrapping
+</div>
+```
+
+### AchievementsDisplay.tsx (Unchanged):
+```
+<GameCard variant="default">     ← Single card wrapper
+  <h3>Achievements</h3>          ← Single heading
+  <ScrollArea>
+    {/* achievement categories */}
+  </ScrollArea>
+</GameCard>
+```
+
+## Summary of Changes Needed:
+
+1. **Remove GameCard wrapper from AchievementsTab.tsx** - Let AchievementsDisplay handle the card
+2. **Remove the h2 heading and badge from AchievementsTab.tsx** - Let AchievementsDisplay handle the heading
+3. **Keep AchievementsDisplay.tsx as-is** - It already has the correct structure
+
+This eliminates the double-nesting and duplicate headings issue.

+# Task 15: Add Mana-Type Capacity Enchantment Effects Per Unlocked Mana Type
+
+## Context Summary
+
+### 1. Current Enchantment Effects for Mana Capacity
+
+**Location**: `/home/user/repos/Mana-Loop/src/lib/game/data/enchantments/mana-effects.ts`
+
+Current mana capacity effects (in `MANA_EFFECTS`):
+- `mana_cap_50` - +50 maximum mana (max 3 stacks)
+- `mana_cap_100` - +100 maximum mana (max 3 stacks)
+- `weapon_mana_cap_20` - +20 weapon mana capacity (max 5 stacks)
+- `weapon_mana_cap_50` - +50 weapon mana capacity (max 3 stacks)
+- `weapon_mana_cap_100` - +100 weapon mana capacity (max 2 stacks)
+
+**Element Capacity Effects**: There are currently NO per-type element capacity enchantment effects. The `elementCap` stat exists in `ComputedEffects` (in `upgrade-effects.ts`) and is applied via:
+- `elementCapBonus` - additive bonus to element max
+- `elementCapMultiplier` - multiplier for element max
+
+These apply globally to ALL elements equally (see `computeElementMax` in `store.ts`).
+
+### 2. Mana Types That Are Unlockable
+
+**Location**: `/home/user/repos/Mana-Loop/src/lib/game/constants/elements.ts`
+
+**Base Elements** (cat: "base"):
+- `fire` - Fire 🔥
+- `water` - Water 💧
+- `air` - Air 🌬️
+- `earth` - Earth ⛰️
+- `light` - Light ☀️
+- `dark` - Dark 🌑
+- `death` - Death 💀
+
+**Utility Elements** (cat: "utility"):
+- `transference` - Transference 🔗 (ALREADY UNLOCKED by default in `BASE_UNLOCKED_ELEMENTS`)
+
+**Composite Elements** (cat: "composite", require recipe to craft):
+- `metal` - Metal ⚙️ (recipe: fire + earth)
+- `sand` - Sand ⏳ (recipe: earth + water)
+- `lightning` - Lightning ⚡ (recipe: fire + air)
+
+**Exotic Elements** (cat: "exotic", require complex recipes):
+- `crystal` - Crystal 💎 (recipe: sand + sand + light)
+- `stellar` - Stellar ⭐ (recipe: fire + fire + light)
+- `void` - Void 🕳️ (recipe: dark + dark + death)
+
+**Total unlockable mana types**: 12 (all except `transference` which starts unlocked)
+
+### 3. How to Add Per-Type Capacity Effects
+
+**Current Effect System Architecture**:
+
+1. **Effect Definition** (`EnchantmentEffectDef` in `/src/lib/game/data/enchantment-types.ts`):
+   - Effects have a `stat` field that identifies what they modify
+   - Stats like `maxMana`, `regen`, `clickMana`, `elementCap` are supported
+   - Effects can be of type: `bonus` (additive), `multiplier`, or `special`
+
+2. **Current Element Cap System** (`/src/lib/game/upgrade-effects.ts` and `/src/lib/game/effects.ts`):
+   - `elementCapBonus` - additive bonus in `ComputedEffects`
+   - `elementCapMultiplier` - multiplier in `ComputedEffects`
+   - Applied in `computeElementMax()` in `store.ts`:
+     ```typescript
+     export function computeElementMax(state, effects?): number {
+       const pu = state.prestigeUpgrades;
+       const base = 10 + (state.skills.elemAttune || 0) * 50 + (pu.elementalAttune || 0) * 25;
+       if (effects) {
+         return Math.floor((base + effects.elementCapBonus) * effects.elementCapMultiplier);
+       }
+       return base;
+     }
+     ```
+
+3. **Approach to Add Per-Type Capacity Effects**:
+
+   **Option A: Extend the stat system with per-element prefixes**
+   - Add new stats like `elementCap_fire`, `elementCap_water`, etc.
+   - Modify `computeElementMax` to accept element parameter
+   - Modify `computeAllEffects` to handle per-element bonuses
+   
+   **Option B: Use a single stat with element metadata (Recommended)**
+   - Add effects with stat format: `elementCap_fire`, `elementCap_water`, etc.
+   - In `computeEquipmentEffects`, parse the element from stat name
+   - Store per-element bonuses in a `Record<string, number>` map
+   - Modify `computeElementMax` to accept element and look up per-element bonus
+   
+   **Option C: Add a new effect type for element-specific bonuses**
+   - Add new effect structure: `{ type: 'elementBonus', element: string, stat: 'capacity', value: number }`
+   - Requires modifying `EnchantmentEffectDef` type
+
+4. **Implementation Steps** (using Option B):
+   
+   a. **Define new enchantment effects** in `mana-effects.ts`:
+   ```typescript
+   fire_cap_10: {
+     id: 'fire_cap_10',
+     name: 'Fire Reservoir',
+     description: '+10 Fire mana capacity',
+     category: 'mana',
+     baseCapacityCost: 25,
+     maxStacks: 5,
+     allowedEquipmentCategories: MANA_EQUIPMENT,
+     effect: { type: 'bonus', stat: 'elementCap_fire', value: 10 }
+   }
+   // Repeat for each element: water, air, earth, light, dark, death, metal, sand, lightning, crystal, stellar, void
+   ```
+
+   b. **Update `ComputedEffects`** in `upgrade-effects.ts` to add per-element storage:
+   ```typescript
+   export interface ComputedEffects {
+     // ... existing fields
+     perElementCapBonus: Record<string, number>;  // New: per-element capacity bonuses
+   }
+   ```
+
+   c. **Update `computeEquipmentEffects`** in `effects.ts` to parse element-specific stats:
+   ```typescript
+   // In the bonus processing:
+   if (effect.stat.startsWith('elementCap_')) {
+     const element = effect.stat.replace('elementCap_', '');
+     bonuses.perElementCapBonus[element] = (bonuses.perElementCapBonus?.[element] || 0) + effect.value * ench.stacks;
+   }
+   ```
+
+   d. **Update `computeElementMax`** in `store.ts` to use per-element bonuses:
+   ```typescript
+   export function computeElementMax(state, effects?, element?: string): number {
+     const base = 10 + (state.skills.elemAttune || 0) * 50 + ...;
+     if (effects) {
+       let bonus = effects.elementCapBonus; // Global bonus
+       if (element && effects.perElementCapBonus?.[element]) {
+         bonus += effects.perElementCapBonus[element];
+       }
+       return Math.floor((base + bonus) * effects.elementCapMultiplier);
+     }
+     return base;
+   }
+   ```
+
+   e. **Update `unlockElement`** in `store.ts` to check for per-element capacity bonuses when unlocking
+
+5. **Effect Unlocking**: New effects should be unlocked via:
+   - `BASE_UNLOCKED_EFFECTS` - effects available from game start
+   - `EFFECT_RESEARCH_MAPPING` - effects unlocked by leveling specific skills
+   - `ENCHANTING_UNLOCK_EFFECTS` - effects unlocked by leveling enchanting skill
+
+### 4. Key Files to Modify
+
+1. `/src/lib/game/data/enchantments/mana-effects.ts` - Add per-element capacity effects
+2. `/src/lib/game/upgrade-effects.ts` - Update `ComputedEffects` interface, add per-element cap handling
+3. `/src/lib/game/effects.ts` - Update `computeEquipmentEffects` to parse element-specific stats
+4. `/src/lib/game/store.ts` - Update `computeElementMax` to accept element parameter and use per-element bonuses
+5. `/src/lib/game/constants/index.ts` or relevant constants file - Add new effects to unlockable lists if needed
+
+### 5. Allowed Equipment Categories
+
+For reference, from `enchantment-types.ts` and existing effects:
+- `MANA_EQUIPMENT: EquipmentCategory[] = ['caster', 'catalyst', 'head', 'body', 'accessory']`
+- Per-type capacity effects should likely use `MANA_EQUIPMENT` or similar
+
+### 6. Existing Related Special Effect
+
+`ELEMENTAL_AFFINITY` special effect (`SPECIAL_EFFECTS.ELEMENTAL_AFFINITY`):
+- When unlocking a new element, starts with 10 capacity instead of 0
+- This is already implemented in `unlockElement` in `store.ts`

+# Task 16: Gate Mana Capacity Research Visibility by Unlocked Mana Type (PRIORITY 4b)
+
+## Context Summary
+
+### 1. How Research Nodes Are Currently Filtered/Displayed
+
+**Location:** `/home/user/repos/Mana-Loop/src/components/game/tabs/SkillsTab.tsx`
+
+**Current Filtering Mechanism:**
+- Skills are organized by categories defined in `SKILL_CATEGORIES` (from `/home/user/repos/Mana-Loop/src/lib/game/constants/skills.ts`)
+- The `SkillsTab` component uses `getAvailableSkillCategories(store.attunements || {})` to determine which skill categories to display
+- `getAvailableSkillCategories` (from `/home/user/repos/Mana-Loop/src/lib/game/data/attunements.ts`) returns categories based on active attunements:
+  - Always available: `'mana'`, `'study'`, `'research'`, `'ascension'`
+  - Enchanter attunement adds: `'enchant'`, `'effectResearch'`
+  - Invoker attunement adds: `'invocation'`, `'pact'`
+  - Fabricator attunement adds: `'fabrication'`, `'golemancy'`
+  - Legacy: `'craft'`
+
+**Skill Display Logic (SkillsTab.tsx lines 200-220):**
+```typescript
+const availableCategories = getAvailableSkillCategories(store.attunements || {});
+return SKILL_CATEGORIES
+  .filter(cat => availableCategories.includes(cat.id))
+  .map((cat) => {
+    const skillsInCat = Object.entries(SKILLS_DEF).filter(([, def]) => def.cat === cat.id);
+    // ... render skills
+  });
+```
+
+**Prerequisites Checking (SkillsTab.tsx lines 269-280):**
+- Skills check `def.req` (skill prerequisites)
+- Skills check `def.attunementReq` (attunement level requirements)
+- Skills with element costs check if player has enough element mana (but skill is still VISIBLE)
+
+**Key Point:** Mana capacity research skills (e.g., `fireManaCap`, `waterManaCap`) are currently ALWAYS visible in the "Mana" category (which is always available). They just show as "cannot study" if the player lacks the required element mana.
+

+
+### 2. Unlocked Mana Types State
+
+**Location:** `/home/user/repos/Mana-Loop/src/lib/game/store.ts` and `/home/user/repos/Mana-Loop/src/lib/game/types/elements.ts`
+
+**GameState Elements Structure:**
+```typescript
+elements: Record<string, ElementState>;
+```
+
+**ElementState Interface:**
+```typescript
+interface ElementState {
+  current: number;    // Current mana amount
+  max: number;         // Maximum capacity
+  unlocked: boolean;   // Whether this element type is unlocked
+}
+```
+
+**Base Unlocked Elements:**
+- Defined in `/home/user/repos/Mana-Loop/src/lib/game/constants/elements.ts`
+- `BASE_UNLOCKED_ELEMENTS = ['transference']` - Only transference is unlocked at game start
+
+**Element Unlocking Mechanisms:**
+1. **`unlockElement(element)` action** (store.ts line 2123): Costs 500 raw mana, sets `unlocked: true`
+2. **`craftComposite(target)` action**: Automatically unlocks composite elements when crafted
+3. **Enchanter attunement**: Auto-unlocks transference element (store.ts line 695)
+
+**All Element Types (from ELEMENTS constant):**
+- Base: `fire`, `water`, `air`, `earth`, `light`, `dark`, `death`
+- Utility: `transference`
+- Composite: `metal` (fire+earth), `sand` (earth+water), `lightning` (fire+air)
+- Exotic: `crystal` (sand+sand+light), `stellar` (fire+fire+light), `void` (dark+dark+death)

+
+### 3. Mana Capacity Research Skills
+
+**Location:** `/home/user/repos/Mana-Loop/src/lib/game/constants/skills.ts`
+
+**Mana Capacity Research Nodes (lines 9-21):**
+```typescript
+// Per-mana-type capacity upgrades (Bug 9)
+fireManaCap:    { name: "Fire Mana Capacity +10%", desc: "...", cat: "mana", max: 10, base: 200, studyTime: 4, cost: { type: 'element', element: 'fire', amount: 100 } },
+waterManaCap:   { name: "Water Mana Capacity +10%", cat: "mana", cost: { type: 'element', element: 'water', amount: 100 } },
+airManaCap:     { name: "Air Mana Capacity +10%", cat: "mana", cost: { type: 'element', element: 'air', amount: 100 } },
+earthManaCap:   { name: "Earth Mana Capacity +10%", cat: "mana", cost: { type: 'element', element: 'earth', amount: 100 } },
+lightManaCap:   { name: "Light Mana Capacity +10%", cat: "mana", cost: { type: 'element', element: 'light', amount: 150 } },
+darkManaCap:    { name: "Dark Mana Capacity +10%", cat: "mana", cost: { type: 'element', element: 'dark', amount: 150 } },
+deathManaCap:   { name: "Death Mana Capacity +10%", cat: "mana", cost: { type: 'element', element: 'death', amount: 200 } },
+// Composite element capacity upgrades
+metalManaCap:   { name: "Metal Mana Capacity +10%", cat: "mana", cost: { type: 'element', element: 'metal', amount: 250 } },
+sandManaCap:    { name: "Sand Mana Capacity +10%", cat: "mana", cost: { type: 'element', element: 'sand', amount: 250 } },
+lightningManaCap: { name: "Lightning Mana Capacity +10%", cat: "mana", cost: { type: 'element', element: 'lightning', amount: 250 } },
+// Utility mana capacity upgrades
+transferenceManaCap: { name: "Transference Mana Capacity +10%", cat: "mana", cost: { type: 'element', element: 'transference', amount: 100 } },
+```
+
+**Key Observation:** Each mana capacity skill has:
+- `cost.type: 'element'`
+- `cost.element`: The element type this skill applies to
+- `cost.amount`: The element mana required to study
+
+---
+
+### 4. How to Gate Capacity Research by Unlocked Mana Type
+
+**Objective:** Hide mana capacity research skills unless the corresponding element type is unlocked.
+
+**Implementation Approach:**
+
+1. **In SkillsTab.tsx, add filtering logic for mana capacity skills:**
+
+   When rendering skills in the "mana" category, check if the skill:
+   - Has `def.cost?.type === 'element'`
+   - AND `store.elements[def.cost.element]?.unlocked === true`
+
+2. **Modified SkillsTab rendering (around line 220):**
+   ```typescript
+   {skillsInCat.map(([id, def]) => {
+     // GATE MANA CAPACITY SKILLS BY UNLOCKED ELEMENT
+     if (def.cost?.type === 'element') {
+       const element = store.elements[def.cost.element];
+       if (!element?.unlocked) {
+         return null; // Don't render this skill
+       }
+     }
+     // ... rest of skill rendering
+   })}
+   ```
+
+3. **Alternative: Filter at category level (less granular):**
+   - Could filter `skillsInCat` before mapping:
+   ```typescript
+   const visibleSkills = skillsInCat.filter(([id, def]) => {
+     if (def.cost?.type === 'element') {
+       return store.elements[def.cost.element]?.unlocked;
+     }
+     return true; // Show non-element-cost skills
+   });
+   ```
+
+4. **Optional: Show locked state instead of hiding:**
+   - Could show a "locked" badge or tooltip explaining the element needs to be unlocked first
+   - This would require modifying the skill rendering to handle a "locked due to element not unlocked" state
+
+---
+
+### 5. Files to Modify
+
+1. **`/home/user/repos/Mana-Loop/src/components/game/tabs/SkillsTab.tsx`**
+   - Add filtering logic to hide mana capacity research skills when the corresponding element is not unlocked
+   - Location: Around line 220 in the `skillsInCat.map()` function
+
+2. **No backend/store changes needed** - The `unlocked` state already exists in `store.elements`. This is purely a UI/display change.
+
+---
+
+### 6. Testing Considerations
+
+- Test that `fireManaCap` is hidden when `store.elements['fire'].unlocked === false`
+- Test that `fireManaCap` becomes visible after calling `store.unlockElement('fire')`
+- Test that non-element-cost skills (like `manaWell`, `manaFlow`) are always visible
+- Test composite element skills (`metalManaCap`, etc.) hide/show correctly
+- Test that the "Mana" category still shows other non-gated skills even when some are hidden
+
+---
+
+### 7. Related Task Context
+
+This task is related to:
+- **Task 9 (Bug 9)**: Per-mana-type capacity upgrades - the skills being gated were added in this task
+- **Task 12 (Bug 12)**: Research moved to Mana category - this is why capacity research is in the "mana" category
+
+---
+
+**Summary:** The gating logic needs to be added to `SkillsTab.tsx` to filter out mana capacity research skills (`*ManaCap`) when `store.elements[element].unlocked` is `false`. The state already tracks unlocked elements, so no store changes are needed.

+# Task 17: Fix Skill Requirement Display Bug (undefined Lv.[object Object])
+
+## Summary
+
+This bug causes skills to display "Requires: [Skill Name] Lv.[object Object]" instead of the proper level requirement. The root cause is that `cost` objects are incorrectly placed INSIDE the `req` (requirements) object in `skills.ts`, causing the rendering code to iterate over the cost object as if it were a skill requirement.
+
+## Root Cause
+
+In `/home/user/repos/Mana-Loop/src/lib/game/constants/skills.ts`, several skill entries have the `cost` property incorrectly nested inside the `req` object.
+
+### Correct Format (cost OUTSIDE req):
+```typescript
+researchFireSpells: { 
+  name: "Fire Spell Research", 
+  desc: "...", 
+  cat: "effectResearch", 
+  max: 1, 
+  base: 300, 
+  studyTime: 6, 
+  req: { enchanting: 2 }, 
+  cost: { type: 'element', element: 'fire', amount: 100 }, 
+  attunementReq: { enchanter: 1 } 
+}
+```
+
+### Malformed Format (cost INSIDE req - BUG):
+```typescript
+researchLifeDeathSpells: { 
+  name: "Death Research", 
+  desc: "...", 
+  cat: "effectResearch", 
+  max: 1, 
+  base: 400, 
+  studyTime: 8, 
+  req: { enchanting: 3 , cost: { type: 'element', element: 'death', amount: 100 }},  // BUG: cost inside req
+  attunementReq: { enchanter: 2 } 
+}
+```
+
+## Malformed Skill Entries
+
+The following skills have `cost` incorrectly placed inside `req` (lines in skills.ts):
+
+1. **researchLifeDeathSpells** (line 51)
+2. **researchAdvancedFire** (line 54)
+3. **researchAdvancedWater** (line 55)
+4. **researchAdvancedAir** (line 56)
+5. **researchAdvancedEarth** (line 57)
+6. **researchAdvancedLight** (line 58)
+7. **researchAdvancedDark** (line 59)
+8. **researchMasterFire** (line 62)
+9. **researchMasterWater** (line 63)
+10. **researchMasterEarth** (line 64)
+11. **researchMetalSpells** (line 86)
+12. **researchSandSpells** (line 87)
+13. **researchLightningSpells** (line 88)
+14. **researchAdvancedMetal** (line 91)
+15. **researchAdvancedSand** (line 92)
+16. **researchAdvancedLightning** (line 93)
+17. **researchMasterMetal** (line 96)
+18. **researchMasterSand** (line 97)
+19. **researchMasterLightning** (line 98)
+
+Total: **19 malformed skill entries**
+
+## How Skill Requirements are Rendered
+
+In `/home/user/repos/Mana-Loop/src/components/game/tabs/SkillsTab.tsx` (lines 233-235):
+
+```tsx
+{!prereqMet && def.req && (
+  <div className="text-xs text-red-400 mt-1">
+    Requires: {Object.entries(def.req).map(([r, rl]) => `${SKILLS_DEF[r]?.name} Lv.${rl}`).join(', ')}
+  </div>
+)}
+```
+
+The code expects `def.req` to be `Record<string, number>` (skill ID -> required level). When `cost` is inside `req`, the iteration produces entries like:
+- `[ "enchanting", 3 ]` → "Enchanting Lv.3" ✓
+- `[ "cost", { type: 'element', ... } ]` → "undefined Lv.[object Object]" ✗
+
+## The Fix
+
+For each malformed entry in `skills.ts`, move the `cost` property OUT of the `req` object:
+
+**Before:**
+```typescript
+req: { enchanting: 3 , cost: { type: 'element', element: 'death', amount: 100 }}
+```
+
+**After:**
+```typescript
+req: { enchanting: 3 }, cost: { type: 'element', element: 'death', amount: 100 }
+```
+
+## Files to Modify
+
+1. `/home/user/repos/Mana-Loop/src/lib/game/constants/skills.ts` - Fix 19 malformed skill entries
+
+## No Changes Needed In
+
+- `/home/user/repos/Mana-Loop/src/components/game/tabs/SkillsTab.tsx` - Rendering code is correct
+- `/home/user/repos/Mana-Loop/src/lib/game/formatting.ts` - Not related to this bug
+- `/home/user/repos/Mana-Loop/src/lib/game/types/skills.ts` - Type definitions are correct
+
+## Steps to Fix
+
+1. Edit `/home/user/repos/Mana-Loop/src/lib/game/constants/skills.ts`
+2. For each of the 19 malformed entries, move `cost` from inside `req` to be a separate property
+3. Verify the fix by checking that `Object.entries(def.req)` only returns skill ID/level pairs
+4. Run typecheck and lint to confirm no errors

+
+### Effect Type in Skill Evolution
+All these perks use the effect structure:
+```typescript
+{ type: 'multiplier', stat: 'enchantPower', value: <decimal_value> }
+```
+
+### Problem: `enchantPower` Stat Not Handled in Effects System
+In `src/lib/game/upgrade-effects.ts`, the `computeEffects` function has a switch statement for multiplier effects (lines 295-320) but **does NOT have a case for `enchantPower`**:
+
+```typescript
+switch (effect.stat) {
+  case 'maxMana':
+    effects.maxManaMultiplier *= effect.value;
+    break;
+  case 'regen':
+    effects.regenMultiplier *= effect.value;
+    break;
+  // ... other cases ...
+  // NO CASE FOR 'enchantPower'!
+}
+```
+
+Similarly, the `ComputedEffects` interface (lines 16-48) does NOT include an `enchantPower` or `enchantmentPowerMultiplier` field.
+
+### StatsTab.tsx Attempts to Read `enchantPower`
+In `src/components/game/tabs/StatsTab.tsx` (lines 161-178), there's a placeholder that tries to read `enchantPower`:
+```typescript
+{upgradeEffects && 'enchantPower' in upgradeEffects 
+  ? `${(upgradeEffects as Record<string, number>).enchantPower.toFixed(2)}×` 
+  : '1.0×'}
+```
+This is a type-safe workaround since `enchantPower` is not in the `ComputedEffects` interface.

+
+## Effects System Overview
+
+### How Effects Are Applied
+
+The effects system is implemented across two main files:
+
+#### 1. `src/lib/game/upgrade-effects.ts` - Skill Upgrade Effects
+- **Interface:** `ComputedEffects` (lines 16-48)
+- **Function:** `computeEffects()` (lines 260-330)
+- Processes skill upgrade effects from `skillUpgrades` and `skillTiers`
+- Handles three effect types:
+  - `multiplier` - multiplies a stat (e.g., `maxMana`, `regen`, `clickMana`)
+  - `bonus` - adds to a stat (e.g., `maxMana`, `regen`, `baseDamage`)
+  - `special` - adds a special effect ID to the `specials` set
+
+#### 2. `src/lib/game/effects.ts` - Unified Effects (Skill + Equipment)
+- **Function:** `computeEquipmentEffects()` (lines 20-78)
+  - Processes equipped item enchantments
+  - Returns `bonuses`, `multipliers`, and `specials`
+  - For each enchantment:
+    - `bonus` type: adds `effect.value * ench.stacks` to `bonuses[effect.stat]`
+    - `multiplier` type: multiplies `multipliers[effect.stat]` by `effect.value` for each stack
+    - `special` type: adds `effect.specialId` to `specials` set
+
+- **Function:** `computeAllEffects()` (lines 91-137)
+  - Merges skill upgrade effects with equipment effects
+  - Merging strategy:
+    - Bonuses: ADD together
+    - Multipliers: MULTIPLY together
+    - Specials: UNION of sets
+
+### Where Enchantment Power Multiplier Would Go
+
+The `enchantmentPower` (or `enchantPower`) multiplier should:
+
+1. **Be added to `ComputedEffects` interface** in `upgrade-effects.ts`:
+   ```typescript
+   enchantmentPowerMultiplier: number; // defaults to 1
+   ```
+
+2. **Be handled in `computeEffects()` switch statement** in `upgrade-effects.ts`:
+   ```typescript
+   case 'enchantPower':
+     effects.enchantmentPowerMultiplier *= effect.value;
+     break;
+   ```
+
+3. **Be applied in `computeEquipmentEffects()` or `computeAllEffects()`** in `effects.ts`:
+   - Option A: Apply to `effect.value` when processing each enchantment
+   - Option B: Apply as an additional multiplier in `computeAllEffects()`
+
+The most logical place is in `computeEquipmentEffects()` where enchantment values are calculated:
+```typescript
+// When processing bonus effects:
+bonuses[effect.stat] = (bonuses[effect.stat] || 0) + effect.value * ench.stacks * enchantmentPowerMultiplier;
+
+// When processing multiplier effects:
+// Each stack applies the multiplier, also modified by enchantmentPowerMultiplier
+for (let i = 0; i < ench.stacks; i++) {
+  multipliers[key] *= (effect.value - 1) * enchantmentPowerMultiplier + 1;
+  // OR simpler: just multiply the final multiplier by enchantmentPowerMultiplier
+}
+```
+
+### Current Multiplier Application (from effects.ts lines 48-57):
+```typescript
+} else if (effect.type === 'multiplier' && effect.stat && effect.value) {
+  // Multiplier effects multiply together
+  const key = effect.stat;
+  if (!multipliers[key]) {
+    multipliers[key] = 1;
+  }
+  // Each stack applies the multiplier
+  for (let i = 0; i < ench.stacks; i++) {
+    multipliers[key] *= effect.value;
+  }
+}
+```
+
+**Note:** The `enchantmentPower` multiplier would need to be passed into `computeEquipmentEffects()` or applied after the fact in `computeAllEffects()`.
+
+---
+
+## Summary of Required Changes for Task 5 (Enchantment Power)
+
+1. Add `enchantmentPowerMultiplier` field to `ComputedEffects` interface
+2. Handle `enchantPower` stat in `computeEffects()` switch statement
+3. Pass `enchantmentPowerMultiplier` to `computeEquipmentEffects()` or apply in `computeAllEffects()`
+4. Update EquipmentTab.tsx stub to display actual value
+5. Update StatsTab.tsx to use proper type-safe access for `enchantmentPowerMultiplier`
+
+---
+
+## Results (Task 18 Implementation)
+
+### Implemented Changes
+
+1. **Added `enchantmentPowerMultiplier` to `ComputedEffects` interface** in `src/lib/game/upgrade-effects.ts`:
+   - Added field `enchantmentPowerMultiplier: number;` to the interface
+   - Initialized to `1` in the `computeEffects()` function
+
+2. **Handled `enchantPower` stat in `computeEffects()` switch statement** in `src/lib/game/upgrade-effects.ts`:
+   - Added case for `enchantPower` in the multiplier effects switch statement
+   - Multiplier is applied as: `effects.enchantmentPowerMultiplier *= effect.value;`
+
+3. **Updated `computeEquipmentEffects()` to apply `enchantmentPowerMultiplier`** in `src/lib/game/effects.ts`:
+   - Added optional parameter `enchantmentPowerMultiplier: number = 1.0`
+   - Applied multiplier to both bonus and multiplier effect values:
+     - `const adjustedValue = effect.value * enchantmentPowerMultiplier;`
+     - Used `adjustedValue` instead of `effect.value` when computing enchantment effects
+
+4. **Updated `computeAllEffects()` to pass the multiplier** in `src/lib/game/effects.ts`:
+   - Now passes `upgradeEffects.enchantmentPowerMultiplier` to `computeEquipmentEffects()`
+
+5. **Replaced stub in EquipmentTab.tsx**:
+   - Changed from: "Increases the power of all enchantments. Will be wired from Task 5 implementation."
+   - Changed to: "Increases the power of all enchantments by X%. Multiplier applied to all enchantment effects."
+   - Now displays actual `enchantmentPowerMultiplier` value from `getUnifiedEffects(store)`
+   - Added `getUnifiedEffects` import from `@/lib/game/effects`
+
+6. **Updated StatsTab.tsx to use type-safe access**:
+   - Changed from type cast workaround: `(upgradeEffects as Record<string, number>).enchantPower`
+   - Changed to proper access: `upgradeEffects?.enchantmentPowerMultiplier`
+   - Now displays the actual multiplier value and percentage
+
+### Audit of Other Unwired Stubs
+
+1. **AttunementsTab.tsx - Disenchanting TODO (Line 198)**: Logged in `docs/task5.md` under "Known Gaps" - waiting for Bug 13
+2. **AttunementsTab.tsx - Research TODO (Line 249)**: Logged in `docs/task5.md` under "Known Gaps" - waiting for Bug 12
+3. **AttunementsTab.tsx.backup - TODOs**: Backup file - ignored
+4. **skill-evolution.ts - Attunement Requirement Placeholder (Line 2218)**: Logged in `docs/task5.md` under "Known Gaps" - placeholder for future implementation
+5. **StatsTab.tsx - Enchantment Power**: ✅ Fixed (was already labeled "Wired" but now properly implemented)
+
+### Files Modified
+- `src/lib/game/upgrade-effects.ts` - Added `enchantmentPowerMultiplier` field and handler
+- `src/lib/game/effects.ts` - Updated `computeEquipmentEffects()` and `computeAllEffects()` to apply multiplier
+- `src/components/game/tabs/EquipmentTab.tsx` - Replaced stub, added import, displays actual value
+- `src/components/game/tabs/StatsTab.tsx` - Updated to use type-safe access for `enchantmentPowerMultiplier`
+- `docs/task5.md` - Added "Known Gaps" section documenting unwired stubs
+
+### Testing Notes
+- The `enchantmentPowerMultiplier` defaults to `1.0` (no effect)
+- Skill perks that use `{ type: 'multiplier', stat: 'enchantPower', value: <decimal> }` will now properly affect enchantment power
+- All enchantment effect values (both bonus and multiplier types) are multiplied by `enchantmentPowerMultiplier`
+- The multiplier is applied per stack (each stack's effect value is multiplied)
+
+### Status
+✅ All tasks completed successfully

+# Task 19 (5a) Context: New Insight Upgrade Proposals
+
+## 1. Existing Insight Upgrades
+Sourced from `docs/GAME_BRIEFING.md` Prestige/Loop System section. These are permanent upgrades purchased with Insight when prestiging (looping), persisting across all subsequent loops.
+
+| Upgrade | Max Level | Cost (Insight) | Effect |
+|---------|-----------|----------------|--------|
+| Mana Well | 5 | 500 | +500 starting max mana |
+| Mana Flow | 10 | 750 | +0.5 permanent regen per level |
+| Deep Memory | 5 | 1000 | +1 memory slot per level |
+| Insight Amp | 4 | 1500 | +25% insight gain per level |
+| Spire Key | 5 | 4000 | Start at floor +2 per level |
+| Temporal Echo | 5 | 3000 | +10% mana generation per level |
+| Steady Hand | 5 | 1200 | -15% durability loss per level |
+| Ancient Knowledge | 5 | 2000 | Start with blueprint per level |
+| Elemental Attune | 10 | 600 | +25 element cap per level |
+| Spell Memory | 3 | 2500 | Start with random spell per level |
+| Guardian Pact | 5 | 3500 | +10% pact multiplier per level |
+| Quick Start | 3 | 400 | +100 starting mana per level |
+| Elem. Start | 3 | 800 | +5 each unlocked element per level |
+
+*Note: In-game core skills (e.g., `mana` category skills like Mana Well, Mana Flow) are distinct from these Prestige/Insight upgrades, which are purchased with Insight across loops.*
+
+## 2. Insight Upgrade Philosophy
+Insight upgrades are **permanent cross-loop advantages that accelerate early-loop ramp-up**. They are designed to:
+- Persist indefinitely across all loops (permanent)
+- Apply universally to every new loop (cross-loop)
+- Reduce the time/effort required to reach mid/late game in each subsequent loop (accelerate early-loop ramp-up)
+
+Examples of existing upgrades aligning with this philosophy:
+- `Quick Start`: Grants starting mana to immediately begin actions
+- `Elem. Start`: Unlocks elemental mana types earlier, bypassing early-game grinds
+- `Spire Key`: Skips low-level floors to reach higher content faster
+
+## 3. Specific Proposal Directions (Task 19 / 5a)
+New Insight upgrade proposals to expand early-loop acceleration options:
+
+1. **Unlocked mana type capacity**
+   - Effect: Start with access to unlocked mana types + small capacity bonus
+   - Goal: Reduce early-game mana type unlock grind, provide immediate elemental mana access
+
+2. **Reduced attunement conversion cost at loop start**
+   - Effect: Lower raw mana cost for converting to elemental mana via attunements early in the loop
+   - Goal: Speed up elemental mana accumulation in first few days of each loop
+
+3. **Start with N floors of Spire progress cleared**
+   - Effect: Begin each loop with N floors of Spire progress already completed (similar to Spire Key, but more granular)
+   - Goal: Skip repetitive early floor climbs, focus on higher content sooner
+
+4. **Guardian Pact memory**
+   - Effect: Retain one pact bonus (from a previously signed Guardian) across loops
+   - Goal: Maintain powerful Guardian boons without re-signing pacts every loop
+
+5. **Skill head-start**
+   - Effect: Start each loop with 1 level in a chosen skill category (e.g., mana, study, enchant)
+   - Goal: Reduce early-game skill grind, immediately access core skill bonuses

+## Special Floor Properties
+
+### Currently Implemented Properties
+
+#### Armor (Damage Reduction)
+- **Guardian floors**: Defined in `GUARDIANS[floor].armor` (0.10 to 0.35)
+- **Non-guardian floors**: Randomly generated via `getFloorArmor(floor)` using `FLOOR_ARMOR_CONFIG`
+- **Swarm enemies**: `SWARM_CONFIG.armorBase + Math.floor(floor / 10) * SWARM_CONFIG.armorPerFloor`
+- Displayed in UI with shield icon and percentage
+
+#### Dodge Chance
+- **Speed rooms only**: Generated via `getDodgeChance(floor)` using `SPEED_ROOM_CONFIG`
+- Base: 25%, scales +0.5% per floor, max 50%
+- Displayed in UI with wind icon and percentage
+
+#### Health/HP
+- **Guardian floors**: `GUARDIANS[floor].hp` (5000 to 1000000)
+- **Normal floors**: `getFloorMaxHP(floor)` - scales with floor number
+- **Swarm enemies**: `baseHP * SWARM_CONFIG.hpMultiplier` (40% of normal)
+
+### Properties Mentioned in Task But Not Currently in Floor Config
+- **healthRegen**: Not currently implemented as a floor/enemy property (only exists in guardian boons as `manaRegen` for player)
+- **barrier**: Not currently implemented as a floor/enemy property (only exists as attunement mana type)
+
+Note: The task mentions displaying "Special floor properties (armor%, health regen, barrier, dodge)" but `healthRegen` and `barrier` are not currently implemented in the floor config. These may need to be added as part of this task.

+# Task 9: Fix Climb/Descend Controls - Context Summary
+
+**Status:** Partially done (spam prevention and re-entry resume implemented, button rename incomplete)
+
+## 1. Climbing/Descending State in store.ts
+
+### State Variables (lines 820, 2260):
+- `spireMode: boolean` - Whether player is in Spire Mode
+- `clearedFloors: Record<number, boolean>` - Tracks cleared floors for respawning
+- `climbDirection: 'up' | 'down' | null` - Current climb direction (persisted for re-entry)
+- `isDescending: boolean` - True when actively descending (prevents spam clicking)
+
+### Key Actions:
+- `enterSpireMode()` (line 2253): Sets `spireMode: true`, `currentAction: 'climb'`, `isDescending: false`
+- `climbDownFloor()` (line 2267): 
+  - Checks `isDescending` to prevent spam
+  - Decrements floor by 1 (min floor 1)
+  - Sets `isDescending: true` during descent
+  - Uses `setTimeout` to reset `isDescending: false` after 500ms
+  - Clears/resets floor state in `clearedFloors`
+- `exitSpireMode()` (line 2311): Sets `spireMode: false`, `currentAction: 'meditate'`, `isDescending: false`
+
+### Spam Prevention (COMPLETED):
+- `isDescending` flag prevents multiple rapid clicks
+- Button is disabled when `isDescending` is true
+- 500ms timeout resets the flag after descent completes
+
+### Re-entry Resume (COMPLETED):
+- `climbDirection` is persisted in state
+- `enterSpireMode()` resumes from `climbDirection` state
+- `exitSpireMode()` allows exit at any floor, re-entry resumes at same floor
+
+## 2. Buttons in SpireTab Components and page.tsx
+
+### src/app/page.tsx (Spire Mode UI) - Lines 258-278:
+
+**Climbing Indicator Badge (line 263-266):**
+```tsx
+{store.currentAction === 'climb' && !store.isDescending && (
+  <Badge className="bg-green-900/50 text-green-300 border-green-600">
+    Climbing
+  </Badge>
+)}
+```
+
+**Descend/Climb Button (lines 267-278):**
+```tsx
+<Button
+  variant="outline"
+  className="border-blue-600/50 text-blue-400 hover:bg-blue-900/20"
+  onClick={() => store.climbDownFloor()}
+  disabled={store.isDescending}
+>
+  <ChevronDown className="w-4 h-4 mr-2" />
+  {store.isDescending ? 'Descending…' : 
+   store.currentAction === 'climb' ? 'Climbing' : 
+   'Begin Descent'}
+</Button>
+```
+
+**Current Button Label Logic:**
+- When `isDescending` is true: Shows "Descending…" (with ellipsis) and button is disabled
+- When `currentAction === 'climb'`: Shows "Climbing" 
+- Otherwise: Shows "Begin Descent"
+
+**Enter Spire Mode Button (lines 211-221):**
+```tsx
+<Button
+  className="w-full bg-gradient-to-r from-amber-600 to-orange-600..."
+  onClick={() => store.enterSpireMode()}
+  disabled={!canEnterSpireMode(store)}
+>
+  <Mountain className="w-5 h-5 mr-2" />
+  Climb the Spire
+</Button>
+```
+
+### src/components/game/tabs/SpireTab.tsx:
+- **No climb/descend buttons** - This component only displays floor info, spells, golems, and activity log
+- Has "Enter Spire Mode" button (line 76) with label "Enter Spire Mode" (for non-Spire Mode view)
+- Displays floor information, active spells, golems, and activity log in `simpleMode={true}`
+
+## 3. What Needs to Change for Button Rename
+
+**Requirement:** idle: 'Begin Descent', descending: 'Descending' disabled, climbing: 'Climbing'
+
+**Current Issues:**
+
+1. **"Descending…" vs "Descending"**: The button shows "Descending…" (with ellipsis) when descending, but requirement says "Descending" (without ellipsis)
+
+2. **Button label when climbing**: The current logic shows "Climbing" when `currentAction === 'climb'`, but this is confusing because:
+   - The button's action is to descend (calls `climbDownFloor()`)
+   - The "Climbing" Badge already serves as a separate indicator
+   - When climbing, users may want to descend, so the button should probably say "Begin Descent"
+
+3. **Possible correct implementation:**
+   - Remove the `currentAction === 'climb'` check from button label
+   - Button should always show "Begin Descent" when not descending
+   - Button shows "Descending" (disabled) when descending
+   - Keep the separate "Climbing" Badge as a status indicator
+
+**Suggested Button Code Fix (in page.tsx, lines 274-277):**
+```tsx
+{store.isDescending ? 'Descending' : 'Begin Descent'}
+```
+(Remove the `store.currentAction === 'climb' ? 'Climbing' : 'Begin Descent'` part)
+
+## 4. Summary of Files to Modify
+
+| File | Change Needed |
+|------|---------------|
+| `src/app/page.tsx` | Fix button label logic (lines 274-277) to match requirements |
+| `src/lib/game/store.ts` | No changes needed (spam prevention and re-entry resume implemented) |
+| `src/components/game/tabs/SpireTab.tsx` | No changes needed (no climb/descend buttons) |
+
+## 5. Verification Steps
+
+After making changes:
+1. Test spam prevention: Rapidly click descend button - should only descend once per 500ms
+2. Test re-entry resume: Exit Spire Mode at floor X, re-enter - should resume at floor X
+3. Test button labels:
+   - Idle (not climbing, not descending): Shows "Begin Descent"
+   - Descending: Shows "Descending" (disabled)
+   - Climbing: The separate Badge shows "Climbing", button shows "Begin Descent"

+# Task 5: Insight Upgrade Proposals
+
+## Overview
+These proposals expand the existing Insight upgrade tree with permanent cross-loop advantages that accelerate early-loop ramp-up, aligned with the prestige philosophy defined in `docs/GAME_BRIEFING.md`. Proposals are grouped by thematic category, each with a rationale explaining alignment with core philosophy and gaps addressed in the existing upgrade tree (referenced below).
+
+### Existing Insight Upgrades (Reference)
+| Upgrade | Max Level | Cost (Insight/Level) | Effect |
+|---------|-----------|------------------------|--------|
+| Mana Well | 5 | 500 | +500 starting max mana |
+| Mana Flow | 10 | 750 | +0.5 permanent regen per level |
+| Deep Memory | 5 | 1000 | +1 memory slot per level |
+| Insight Amp | 4 | 1500 | +25% insight gain per level |
+| Spire Key | 5 | 4000 | Start at floor +2 per level |
+| Temporal Echo | 5 | 3000 | +10% mana generation per level |
+| Steady Hand | 5 | 1200 | -15% durability loss per level |
+| Ancient Knowledge | 5 | 2000 | Start with blueprint per level |
+| Elemental Attune | 10 | 600 | +25 element cap per level |
+| Spell Memory | 3 | 2500 | Start with random spell per level |
+| Guardian Pact | 5 | 3500 | +10% pact multiplier per level |
+| Quick Start | 3 | 400 | +100 starting mana per level |
+| Elem. Start | 3 | 800 | +5 each unlocked element per level |
+
+---
+
+## Theme 1: Mana & Elemental Acceleration
+### Rationale
+Existing upgrades in this category (Mana Well, Mana Flow, Elemental Attune, Elem. Start, Temporal Echo) focus on boosting mana generation and elemental access, but leave two critical gaps: (1) no permanent bonus to base capacity for unlocked mana types, and (2) no reduction to attunement conversion costs. These proposals fill those gaps to further reduce early-loop grind for elemental mana setup, a core bottleneck in first-loop progression.
+
+### Proposal 1: Unlocked Mana Type Capacity
+- **Max Level**: 5
+- **Cost**: 1000 Insight per level
+- **Effect**: Start each loop with +10 base capacity per unlocked mana type per level, plus immediate access to all mana types unlocked in any previous loop (no re-unlocking required).
+- **Gap Addressed**: Builds on `Elem. Start` (which grants +5 element cap per level) by adding permanent capacity for all historically unlocked types, eliminating repetitive base capacity grinding for each elemental mana type in early loop.
+- **Implementation Notes**:
+  - Track unlocked mana types across loops in cross-loop save data (`player.insight.unlockedManaTypes`)
+  - Apply capacity bonus on loop initialization via `LoopManager.applyInsightUpgrades()`
+  - Respect existing elemental cap limits from `Elemental Attune` upgrades
+
+### Proposal 2: Attunement Efficiency
+- **Max Level**: 5
+- **Cost**: 800 Insight per level
+- **Effect**: Reduce raw mana cost for elemental mana conversion (attunement) by 5% per level for the first 3 in-loop days.
+- **Gap Addressed**: Existing `Temporal Echo` boosts mana generation but not conversion efficiency. This directly accelerates early elemental mana accumulation, a key bottleneck in first 48 hours of each loop.
+- **Implementation Notes**:
+  - Apply cost reduction modifier to `AttunementStation` component for 72 in-loop hours
+  - Reset modifier automatically after 3-day window
+  - Stack with `Temporal Echo` generation bonuses
+
+---
+
+## Theme 2: Spire Progression Acceleration
+### Rationale
+Existing `Spire Key` (start at +2 floors per level) enables batch-skipping of low-level Spire floors, but lacks granular progression retention. This theme adds finer-grained Spire skip options to let players incrementally bypass repetitive early floors without over-skipping content, aligning with early-loop ramp-up goals.
+
+### Proposal 3: Spire Progress Retention
+- **Max Level**: 10
+- **Cost**: 500 Insight per level
+- **Effect**: Start each loop with 1 additional Spire floor cleared per level (stacks additively with `Spire Key` bonuses).
+- **Gap Addressed**: `Spire Key` only offers +2 floors per level, leaving no option for 1-floor increments. This allows players to tailor skip amount to their progression speed.
+- **Implementation Notes**:
+  - Store highest Spire floor reached per loop in `player.insight.highestSpireFloor`
+  - Apply cleared floors on new loop initialization via `SpireManager.syncProgress()`
+  - Cap total skipped floors at 50 (to prevent over-skipping endgame content)
+
+---
+
+## Theme 3: Guardian & Pact Continuity
+### Rationale
+Existing `Guardian Pact` boosts pact multipliers per level, but requires players to re-sign Guardian pacts each loop to access boons. This theme adds permanent pact memory to retain critical boons across loops, eliminating repetitive pact signing grind.
+
+### Proposal 4: Guardian Pact Memory
+- **Max Level**: 3
+- **Cost**: 3000 Insight per level
+- **Effect**: Retain 1 Guardian pact bonus (selected from previous loop's signed pacts) per level across loops, no re-signing required.
+- **Gap Addressed**: `Guardian Pact` only boosts multiplier strength, not retention. This lets players keep high-value boons (e.g., resource generation, damage resistance) permanently.
+- **Implementation Notes**:
+  - Track signed Guardian pacts per loop in `player.insight.signedGuardians`
+  - Add pact selection UI to prestige screen (`PrestigeModal.tsx`)
+  - Apply retained bonuses on loop start via `GuardianManager.applyRetainedPacts()`
+
+---
+
+## Theme 4: Skill & Knowledge Acceleration
+### Rationale
+Existing upgrades like `Ancient Knowledge` (blueprints), `Spell Memory` (spells), and `Quick Start` (starting mana) accelerate early knowledge/skill access, but leave a gap in core skill category progression. This theme adds skill head-start options to reduce early-game grind for core skill bonuses.
+
+### Proposal 5: Skill Head-Start
+- **Max Level**: 5
+- **Cost**: 600 Insight per level
+- **Effect**: Start each loop with 1 level in a chosen core skill category (mana, study, enchant, combat) per level, selectable during prestige.
+- **Gap Addressed**: No existing upgrade boosts core skill levels at loop start. Builds on `Quick Start`'s immediate resource boost by adding skill progression acceleration.
+- **Implementation Notes**:
+  - Add skill category selector to prestige UI (`PrestigeModal.tsx`)
+  - Apply skill levels on loop initialization via `SkillManager.addLevels()`
+  - Respect per-skill max level caps defined in `skillData.ts`

+    cost: 800 
+  },
+  
+  // ... other upgrades ...
+};
+```
+
+**Key observations:**
+- All prestige upgrades use the same structure: name, description, max level, cost
+- `elementalAttune` already provides +25 elemental mana cap per level (max 10 levels = +250 cap)
+- `elemStart` gives starting elemental mana when a new loop begins
+- Upgrades are stored as `Record<string, number>` where the value is the current level
+
+---
+
+## 2. How Mana Type Unlocks Are Tracked
+
+### Element State Structure
+**File:** `src/lib/game/types/elements.ts`
+```typescript
+export interface ElementState {
+  current: number;
+  max: number;
+  unlocked: boolean;
+}
+```
+
+### Elements Storage in GameState
+**File:** `src/lib/game/types/game.ts`
+```typescript
+export interface GameState {
+  // ...
+  elements: Record<string, ElementState>;
+  // ...
+}
+```
+
+### Base Unlocked Elements
+**File:** `src/lib/game/constants/elements.ts`
+```typescript
+export const BASE_UNLOCKED_ELEMENTS = ['transference'];
+```
+
+**Key observations:**
+- Only `transference` starts unlocked by default
+- All other 12 elements (fire, water, air, earth, light, dark, death, metal, sand, lightning, crystal, stellar, void) start locked
+- Elements have a boolean `unlocked` field - no partial unlocking or limits on number of unlocked types
+
+### Unlocking New Elements
+**File:** `src/lib/game/store.ts` (lines 2176-2195)
+```typescript
+unlockElement: (element: string) => {
+  const state = get();
+  if (state.elements[element]?.unlocked) return;
+
+  const cost = 500;
+  if (state.rawMana < cost) return;
+
+  // ELEMENTAL_AFFINITY: New elements start with 10 capacity
+  const effects = getUnifiedEffects(state.skillUpgrades, state.skillTiers);
+  const newElementMax = hasSpecial(effects, SPECIAL_EFFECTS.ELEMENTAL_AFFINITY) ? 10 : 0;
+
+  set({
+    rawMana: state.rawMana - cost,
+    elements: {
+      ...state.elements,
+      [element]: { ...state.elements[element], unlocked: true, max: newElementMax },
+    },
+    log: [`✨ ${ELEMENTS[element].name} affinity unlocked!`, ...state.log.slice(0, 49)],
+  });
+},
+```
+
+**Key observations:**
+- Unlocking an element costs 500 raw mana
+- When unlocked, the element gets `unlocked: true`
+- New elements start with `max: 0` unless ELEMENTAL_AFFINITY special effect is active (then max: 10)
+- No limit on the NUMBER of elements that can be unlocked - players can unlock all 12+ types
+
+### Element Definitions
+**File:** `src/lib/game/constants/elements.ts`
+
+Total element types:
+- **Base (7):** fire, water, air, earth, light, dark, death
+- **Utility (1):** transference
+- **Composite (3):** metal, sand, lightning
+- **Exotic (3):** crystal, stellar, void
+
+**Total: 14 element types** (13 unlockable + transference which starts unlocked)
+
+---
+
+## 3. How Mana Capacity Is Applied
+
+### computeElementMax Function
+**File:** `src/lib/game/store.ts` (lines 415-432)
+```typescript
+export function computeElementMax(
+  state: Pick<GameState, 'skills' | 'prestigeUpgrades' | 'skillUpgrades' | 'skillTiers'>,
+  effects?: ComputedEffects | UnifiedEffects,
+  element?: string
+): number {
+  const pu = state.prestigeUpgrades;
+  const base = 10 + (state.skills.elemAttune || 0) * 50 + (pu.elementalAttune || 0) * 25;
+  
+  // Apply upgrade effects if provided
+  if (effects) {
+    let bonus = effects.elementCapBonus; // Global bonus
+    
+    // Add per-element bonus if element is specified and available
+    if (element && (effects as UnifiedEffects).perElementCapBonus) {
+      const perElementBonus = (effects as UnifiedEffects).perElementCapBonus[element];
+      if (perElementBonus) {
+        bonus += perElementBonus;
+      }
+    }
+    
+    return Math.floor((base + bonus) * effects.elementCapMultiplier);
+  }
+  return base;
+}
+```
+
+**Key observations:**
+- Base capacity formula: `10 + (elemAttune skill levels * 50) + (elementalAttune prestige levels * 25)`
+- Effects system can modify capacity via:
+  - `elementCapBonus`: Global flat bonus
+  - `elementCapMultiplier`: Global multiplier
+  - `perElementCapBonus[element]`: Per-element flat bonus (from equipment)
+- **Currently, all unlocked elements share the SAME max capacity** (calculated once and applied to all)
+- The `perElementCapBonus` exists but is currently only used for equipment effects
+
+### Usage in Store Initialization
+**File:** `src/lib/game/store.ts` (lines 670-710)
+```typescript
+function makeInitial(overrides: Partial<GameState> = {}): GameState {
+  const pu = overrides.prestigeUpgrades || {};
+  // ...
+  const elemMax = computeElementMax(
+    { skills: overrides.skills || {}, prestigeUpgrades: pu, skillUpgrades: overrides.skillUpgrades, skillTiers: overrides.skillTiers }, 
+    effects
+  );
+  
+  const elements: Record<string, { current: number; max: number; unlocked: boolean }> = {};
+  Object.keys(ELEMENTS).forEach((k) => {
+    const isUnlocked = BASE_UNLOCKED_ELEMENTS.includes(k);
+    let startAmount = 0;
+    
+    // Start with some elemental mana if elemStart upgrade
+    if (isUnlocked && pu.elemStart) {
+      startAmount = pu.elemStart * 5;
+    }
+    
+    elements[k] = {
+      current: overrides.elements?.[k]?.current ?? startAmount,
+      max: elemMax,  // <-- Same max for ALL elements
+      unlocked: isUnlocked,
+    };
+  });
+  // ...
+}
+```
+
+**Key observation:** The same `elemMax` is applied to ALL elements regardless of type or unlock status.
+
+---
+
+## 4. Save Data Structure (Cross-Loop Persistence)
+
+### GameState Prestige-Related Fields
+**File:** `src/lib/game/types/game.ts`
+```typescript
+export interface GameState {
+  // ...
+  
+  // Prestige
+  insight: number;
+  totalInsight: number;
+  prestigeUpgrades: Record<string, number>;
+  memorySlots: number;
+  memories: string[];
+  
+  // Elements
+  elements: Record<string, ElementState>;
+  
+  // ...
+}
+```
+
+### What Persists Through Loops
+**File:** `src/lib/game/store.ts` (lines 2255-2290)
+```typescript
+startNewLoop: () => {
+  const state = get();
+  const insightGained = state.loopInsight || calcInsight(state);
+  const total = state.insight + insightGained;
+  
+  // ... (keep some spells through temporal memory)
+  
+  const newState = makeInitial({
+    loopCount: state.loopCount + 1,
+    insight: total,
+    totalInsight: (state.totalInsight || 0) + insightGained,
+    prestigeUpgrades: state.prestigeUpgrades,  // <-- PERSISTS
+    memories: state.memories,
+    skills: state.skills,
+    manaHeartBonus: newHeartBonus,
+  });
+  
+  // ...
+  set(newState);
+},
+```
+
+**Key observations:**
+- `prestigeUpgrades` (all upgrade levels) persist through loops
+- `insight` and `totalInsight` persist and accumulate
+- `elements` are NOT persisted - they are reinitialized in `makeInitial()`
+- On new loop, element unlocks are lost (player must re-unlock elements)
+- `BASE_UNLOCKED_ELEMENTS` and `pu.elemStart` determine which elements start unlocked/have starting mana
+
+### Purchasing Prestige Upgrades
+**File:** `src/lib/game/store.ts` (lines 2235-2250)
+```typescript
+doPrestige: (id: string) => {
+  // ...
+  const lvl = state.prestigeUpgrades[id] || 0;
+  if (lvl >= pd.max || state.insight < pd.cost) return;
+
+  const newPU = { ...state.prestigeUpgrades, [id]: lvl + 1 };
+  set({
+    insight: state.insight - pd.cost,
+    prestigeUpgrades: newPU,
+    // ...
+  });
+},
+```
+
+**Key observations:**
+- Upgrades purchased with `insight` currency
+- Each level costs the same amount (flat cost model)
+- Max level check prevents over-purchasing
+- New upgrade level is saved to `prestigeUpgrades` record
+
+---
+
+## Summary of Key Points for Task6-1
+
+1. **Prestige upgrades** follow a simple structure: `{ name, desc, max, cost }`
+2. **Element capacity** is currently global (same for all elements), calculated from:
+   - Base: 10
+   - Skill: `elemAttune` levels × 50
+   - Prestige: `elementalAttune` levels × 25
+   - Effects: bonuses and multipliers
+3. **Element unlocks** are per-type (boolean), cost 500 raw mana each
+4. **No limit** on number of unlocked element types currently exists
+5. **Per-element capacity** bonuses exist in effects system (`perElementCapBonus`) but aren't widely used
+6. **Cross-loop persistence:** prestige upgrades and insight persist; element unlocks do NOT persist
+7. **14 total element types** available (13 unlockable + transference)
+
+## Questions for Implementation
+
+Depending on what "Unlocked Mana Type Capacity" means:
+
+**If it means increasing capacity (max mana) of unlocked types:**
+- Could add a new prestige upgrade similar to `elementalAttune`
+- Could modify the `computeElementMax` function
+- Could add per-element capacity tracking
+
+**If it means increasing the NUMBER of types that can be unlocked:**
+- Need to add a limit/cap on unlocked types (currently unlimited)
+- Need to add a prestige upgrade to increase this limit
+- Need to modify `unlockElement` to check against the limit

+
+
+## Assessment: Which exports are safest to extract to a new file
+
+### Safest to extract (stand-alone, reusable, low coupling):
+1. **`TabLoadingFallback`** — A presentational component with zero dependencies on game state or side-effects. It could be moved to a shared UI file (e.g., `components/ui/loading.tsx`) with no behavioral impact.
+
+2. **`canCastSpell`** — Although currently nested inside `ManaLoopGame`, it is a pure function of `(spellId, store)` (it reads `SPELLS_DEF` and `canAffordSpellCost`). It could be lifted to `@/lib/game/spells.ts` (or similar) and exported as a named helper. This would reduce closure complexity and make it easily testable.
+
+### Moderate safety (would require small refactors but are useful to share):
+- None identified beyond the above two — the only other export is the default `ManaLoopGame`, which is intentionally top-level and orchestrates too many concerns to extract as-is. Splitting it would require significant decomposition (e.g., extracting subcomponents, custom hooks, and game-logic helpers).
+
+### Not recommended to extract as-is:
+- **`ManaLoopGame`** — It is the root page component for `/` and tightly integrates routing-lite behavior (spire mode vs normal tabs), game-loop effects, state selectors, and presentation. Extracting it would require first breaking it into smaller pieces (state hooks, subcomponents) rather than moving it wholesale.

+
+---
+
+## Assessment — Safest exports to extract to a new file
+
+**Best candidates for extraction** (low coupling, high reusability, minimal dependencies on store/ui):
+
+1. **`hasMilestoneUpgrade`** (lines ~50–81)  
+   - Pure-ish function that computes milestone eligibility from skill/tier/upgrade state.  
+   - Depends only on `SKILL_EVOLUTION_PATHS`, `getUpgradesForSkillAtMilestone` and primitive arguments.  
+   - No React or store coupling — safest to extract.
+
+2. **`SkillsTabProps`** (interface)  
+   - Type-only export; could be colocated with types or moved to a shared types file if desired.  
+   - Zero runtime cost — safe but typically not worth extracting by itself unless consolidating interfaces.
+
+**Less safe / more complex**:
+
+- **`SkillsTab`** — deeply coupled to store, UI components, hooks, local dialog state, and many domain helpers. Extracting this would require pulling many dependencies and UI coordination; not recommended unless performing a major feature split.  
+- If extraction goal is to reduce file size, consider extracting smaller helpers used *inside* the component into modules (e.g., category filtering, tier/cost calculation helpers) but those are currently inline.
+
+**Recommendation:**  
+Extract `hasMilestoneUpgrade` into a helper file (e.g., `src/lib/game/skill-milestones.ts` or similar) and move `SkillsTabProps` into a shared types file if consolidating. Leave `SkillsTab` in place.

+- Total line count: 191
+
+## Top-Level Exports
+
+1. **`getActiveUpgrades`** (lines ~28-51)
+   - Returns all selected upgrades with full effect definitions from the skill upgrades record
+   - Builds cache of upgrade definitions on first access, iterates over SKILL_EVOLUTION_PATHS
+
+2. **`computeEffects`** (lines ~54-188)
+   - Computes all active effects from selected upgrades into a ComputedEffects object
+   - Applies multipliers, bonuses, and special effects from upgrades; handles DEEP_UNDERSTANDING and MANA_THRESHOLD
+
+3. **`upgradeDefinitionsById`** (line ~15)
+   - Cache Map for quick lookup of upgrade definitions by ID
+
+4. **`buildUpgradeCache`** (lines ~18-25)
+   - Initializes the upgrade definition cache from SKILL_EVOLUTION_PATHS
+
+## Imports
+
+- `SkillUpgradeChoice`, `SkillUpgradeEffect` from './types'
+- `getUpgradesForSkillAtMilestone`, `SKILL_EVOLUTION_PATHS` from './skill-evolution'
+- `ActiveUpgradeEffect`, `ComputedEffects` from './upgrade-effects.types'
+- `SPECIAL_EFFECTS`, `hasSpecial` from './special-effects'
+- `computeDynamicRegen`, `computeDynamicClickMana`, `computeDynamicDamage` from './dynamic-compute'
+
+## Assessment
+
+This file is already **191 lines** (well under 400). No refactoring needed. The exports are cleanly separated - `getActiveUpgrades` handles data gathering, `computeEffects` handles computation. The module is focused on a single concern (upgrade effects) and is not a candidate for splitting.

+# Refactor Plan: page.tsx
+
+## Current State
+- **File:** `src/app/page.tsx`
+- **Lines:** 650
+- **Target:** ≤400 lines (reduce by ~250 lines)
+
+## Proposed File Structure
+
+### 1. `src/components/game/tabs/PrestigeTab.tsx` (NEW, ≈60 lines)
+**Contains:**
+- `PrestigeTab` component (extracted from `renderGrimoireTab`)
+- Grimoire/Prestige tab UI
+
+**Rationale:** Self-contained tab component; only depends on store, PRESTIGE_DEF, GUARDIANS.
+
+### 2. `src/app/page.tsx` (≈300 lines)
+**Keeps:**
+- Main `ManaLoopGame` component shell
+- Tabs definition and lazy loading
+- Core game loop integration
+- Most tab content (other tabs remain via lazy loading)
+
+**Rationale:** Reduces main page by extracting only the Grimoire tab which is standalone.
+
+## Circular Import Risks
+
+**LOW RISK:**
+- `PrestigeTab` depends on store, PRESTIGE_DEF, GUARDIANS - all stable dependencies.
+- No circular dependency with `page.tsx`.
+
+**MITIGATION:**
+- Import store and constants normally in new component.
+
+## Extraction Order
+
+**1 → 2**
+
+1. Create `PrestigeTab.tsx`, move `renderGrimoireTab` content, adapt to be standalone (receive store via hook internally), export component.
+2. Update `page.tsx`: replace `renderGrimoireTab` call with `<PrestigeTab />`, remove extracted code.
+3. Verify typecheck, verify ≤400 lines.
+
+## Notes
+
+This addresses the main line bloat by only ~60 lines (renderGrimoireTab). To get page.tsx under 400 lines fully would require more extensive splitting (extracting each tab into separate route files, extracting sidebar, etc.). The plan here is conservative - if page.tsx is still >400 after extracting PrestigeTab, we can consider:
+- Extracting StatsTab/LabTab content further
+- Extracting activity log rendering
+- Extracting action buttons
+But per phase instructions we must get ALL THREE target files under 400 lines, so we must be more aggressive if needed.

+## Current State
+- **File:** `src/components/game/tabs/SkillsTab.tsx`
+- **Lines:** 434
+- **Target:** ≤400 lines (reduce by ~34 lines)
+
+## Proposed File Structure
+
+### 1. `src/lib/game/utils.ts` (NEW, ≈20 lines)
+**Contains:**
+- `formatStudyTime` function
+
+**Rationale:** Simple pure utility function, zero-risk extraction.
+
+### 2. `src/components/game/tabs/SkillUpgradeDialog.tsx` (NEW, ≈80 lines)
+**Contains:**
+- `SkillUpgradeDialog` component (extracted from `renderUpgradeDialog`)
+- Dialog UI and selection state handlers
+
+**Rationale:** Isolates the upgrade dialog UI (~100 lines worth from parent), simplifies SkillsTab significantly. Uses callback props.
+
+### 3. `src/components/game/SkillRow.tsx` (NEW, ≈100 lines)
+**Contains:**
+- `SkillRow` component for individual skill rows
+- Level dots, buttons, study toggle, tier-up, milestone badges
+
+**Rationale:** Encapsulates per-skill UI (~150 lines worth from parent), reusable, simplifies SkillsTab.
+
+### 4. `src/lib/game/hooks/useSkillUpgradeSelection.ts` (NEW, ≈40 lines)
+**Contains:**
+- `useSkillUpgradeSelection` custom hook
+- Selection state and mutation logic for milestone upgrades
+
+**Rationale:** Encapsulates upgrade selection logic previously inline in SkillsTab.
+
+### 5. `src/components/game/tabs/SkillsTab.tsx` (≈150 lines)
+**Keeps:**
+- Core `SkillsTab` component shell
+- Category-level layout
+- Main store hook calls
+- Tab switching
+
+**Rationale:** Maintains coordination role while delegating details to extracted components/hooks.
+
+## Circular Import Risks
+
+**MEDIUM RISK:**
+- `SkillRow` needs access to many store selectors and actions. May accept callbacks as props to avoid direct store access (kept in parent).
+- `SkillUpgradeDialog` needs data from store; will receive computed values as props.
+- `useSkillUpgradeSelection` needs `SKILL_EVOLUTION_PATHS` and store commits - safe.
+
+**MITIGATION:**
+- Keep store interactions in `SkillsTab`, pass data down via props.
+- Accept slight prop drilling vs. direct store access in extracted components for cleaner boundaries.
+
+## Extraction Order
+
+**1 → 4 → 3 → 2 → 5**
+
+1. Create `utils.ts`, move `formatStudyTime`, update SkillsTab import.
+2. Create `useSkillUpgradeSelection` hook, move selection logic, update SkillsTab.
+3. Create `SkillRow`, move per-skill UI (pass callbacks from parent), update SkillsTab.
+4. Create `SkillUpgradeDialog`, move dialog UI, update SkillsTab.
+5. Delete old extracted sections from SkillsTab, verify ≤400 lines.

+1. Create `upgrade-effects.types.ts`, move type interfaces, update imports.
+2. Create `special-effects.ts`, move `SPECIAL_EFFECTS` + `hasSpecial`, update imports.
+3. Create `dynamic-compute.ts`, move the three `computeDynamic*` functions, update imports.
+4. Trim `upgrade-effects.ts` - remove moved items, update internal imports.
+
+## Import Updates Required
+
+Files importing from `upgrade-effects.ts` need updates:
+- Types → `upgrade-effects.types.ts`
+- Special effects → `special-effects.ts`
+- Dynamic compute → `dynamic-compute.ts`
+- Core functions → `upgrade-effects.ts`
