• Hero.java - search() method (lines 666-710)
• GameScene.java - Calls hero.search(true) for intentional search (line 707)
• Toolbar.java - Search button handler (line 67)
• RingOfDetection.java - Triggers search on equip (line 16)
• BuffFactory.java - RING_OF_DETECTION constant (line 100)

• Intentional Search: Player-initiated search (toolbar button) - uses full awareness formula
• Passive Search: Automatic search each turn - uses reduced awareness formula
• Ring of Detection: Increases search distance by buff level when equipped

``` search(boolean intentional):

distance = 1 + buffLevel(RING_OF_DETECTION)

if intentional:
  searchLevel = 2 * awareness - awareness^2
else:
  searchLevel = awareness

if distance <= 0:
  searchLevel /= 2 - distance
  distance = 1

For each cell in radius 'distance':
  if cell is visible:
    if intentional: add CheckedCell visual effect
    if intentional OR Random.Float() < searchLevel:
      if cell has secret (trap/secret door):
        reveal secret
        return true

```

• Base awareness depends on hero class and level
• Awareness increases with hero level
• Ring of Detection buff level adds to search distance
