Severity: High — large functions are hard to test, reason about, and maintain. Deep nesting obscures control flow.

Findings:

  • page.tsx is 374 LOC with 6 as any casts and deeply nested closures
  • EquipmentCrafter.tsx is 199 LOC with high cyclomatic complexity (>15 branches)
  • GameStateDebug.tsx is 269 LOC
  • Deeply nested closures in 24 files make control flow hard to follow
  • processCraftingTick in crafting-slice.ts has 4 sequential progress processors with nested if/else logic (150+ LOC)

Affected files:

  • src/app/page.tsx
  • src/components/game/crafting/EquipmentCrafter.tsx
  • src/components/game/debug/GameStateDebug.tsx, src/components/game/debug/PactDebug.tsx
  • src/components/game/tabs/GuardianPactsTab.tsx, src/components/game/tabs/PrestigeTab.tsx
  • src/components/game/tabs/SpireCombatPage/SpireCombatPage.tsx, src/components/game/tabs/SpireSummaryTab.tsx
  • src/components/game/tabs/DebugTab/PactDebugSection.tsx, src/components/game/tabs/DebugTab/GameStateDebugSection.tsx
  • src/app/components/LeftPanel.tsx
  • src/lib/game/crafting-slice.ts

Suggested fix: Extract sub-components and helper functions. Use early returns to flatten conditionals. For processCraftingTick, use a pipeline pattern with separate processor functions.

Confidence: High
Dimension: low_level_elegance (score: 62.0%) / design_coherence
