 - [x] 10.7 System signatures updated — `playerInputSystem`, `aiSystem`, `creatureProjectileSystem` accept optional multiplier params
 - [x] Unit tests — 24 new tests (511 total): school data, unlock conditions (cumulative, multi-school, persistence), bonuses per school
 
+### Phase 11: Great Cycle ✅
+- [x] 11.1 GreatCycleState types — CycleTheme enum, RunTrace, GreatCycleState, CycleWorldModifiers (`src/run/types.ts`)
+- [x] 11.2 Great Cycle engine — cycle tracking, theme resolution, trace recording, renewal, world modifiers (`src/run/cycle.ts`)
+- [x] 11.3 MetaState extended — `greatCycle` field, persistence updated, RunState extended with biomeId/worldSeed/deathPosition
+- [x] 11.4 Run trace recording — death position, school, biome, discoveries saved per run via `applyRunResults`
+- [x] 11.5 World trace placement — WorldTrace ECS component, death site markers (dark red), discovery markers (blue), glow animation (`src/world/traces.ts`)
+- [x] 11.6 Cycle narrative data — 6 themes with Russian lore fragments, cradle quotes, renewal messages (`src/data/cycle-narrative.json`)
+- [x] 11.7 RenewalScene — special scene between great cycles: Mycelium particles, staged text reveals, cycle transition, lore, maturation display (`src/scenes/RenewalScene.ts`)
+- [x] 11.8 Mycelium maturation — strengthens all nodes on renewal, caps at 1.0, cumulative across cycles
+- [x] 11.9 CradleScene integration — "Великий Цикл N: Тема | Ран X/7", narrative quote per theme
+- [x] 11.10 UIScene integration — cycle info bar + run phase display below health
+- [x] 11.11 GameScene integration — world trace spawning, trace glow rendering, death position recording, cycle info to registry
+- [x] 11.12 Scene flow extended — Fractal → RenewalScene (on 7th run) → Cradle, or Fractal → Cradle (normal)
+- [x] Unit tests — 51 new tests (562 total): cycle init, themes, traces, advancement, renewal, world modifiers, narrative data, full integration
