+# The Dismantle Sequence (The Unbuilding) — Implementation Status
+
+**Status:** ✅ **COMPLETE**  
+**Last Updated:** 2026-04-14  
+**Related Issues:** #16, #133, #145  
+**Implementation:** `js/dismantle.js` (570 lines)  
+**Tests:** `tests/dismantle.test.cjs` (10/10 passing)
+

+
+## Overview
+
+The Dismantle Sequence (The Unbuilding) is the emotional endgame of The Beacon. Inspired by the Paperclips REJECT path, it strips away UI panels one by one until only a single golden beacon remains — "That is enough."
+
+## Implementation Status
+
+| Component | Status | Notes |
+|-----------|--------|-------|
+| 8-stage dismantle sequence | ✅ Complete | Stages 1-8 + final |
+| Save/load persistence | ✅ Complete | Full state restoration |
+| Defer mechanism | ✅ Complete | "NOT YET" button with cooldown |
+| Final overlay | ✅ Complete | Golden beacon dot + stats |
+| Resource dissolution | ✅ Complete | Quantum chips pattern |
+| Animations | ✅ Complete | Smooth fade-outs |
+| Tests | ✅ Complete | 10/10 passing |
+
+## Stages
+
+### Stage 1: Hide Research Projects Panel
+Hides the `#project-panel` element with fade-out animation.
+
+### Stage 2: Hide Buildings List
+Hides the `#buildings` section and its header.
+
+### Stage 3: Hide Strategy Engine + Combat
+Hides both `#strategy-panel` and `#combat-panel`.
+
+### Stage 4: Hide Education Panel
+Hides the `#edu-panel` element.
+
+### Stage 5: Resource Dissolution
+Resources disappear one by one using the quantum chips pattern:
+- Harmony → Creativity → Trust → Operations → Rescues → Impact → Users → Knowledge → Compute → Code
+- Timed at specific tick marks within the stage
+
+### Stage 6: Hide Action Buttons
+Hides ops buttons, sprint container, and save/reset buttons.
+
+### Stage 7: Hide Phase Bar
+Hides the `#phase-bar` element.
+
+### Stage 8: Hide System Log
+Hides the `#log` panel.
+
+### Final: "That is enough"
+- Golden beacon dot with glow animation
+- "THAT IS ENOUGH" text
+- Stats summary (total code, buildings, projects, rescues, clicks, time played)
+- "PLAY AGAIN" button
+
+## Features
+
+### Defer Mechanism
+- Player can choose "NOT YET" to defer the Unbuilding
+- 5-second cooldown before the prompt reappears
+- Cooldown persists across save/load
+
+### Save/Load Persistence
+- All dismantle state is saved to localStorage
+- Partial progress (e.g., mid-stage-5) restores correctly
+- Defer cooldown survives save/load
+
+### Resource Dissolution (Quantum Chips Pattern)
+Resources disappear at specific tick marks within stage 5:
+```javascript
+RESOURCE_TICKS: [1.0, 2.0, 3.0, 4.0, 5.0, 5.5, 5.8, 5.95, 6.05, 6.12]
+```
+This creates a dramatic acceleration effect as resources dissolve faster and faster.
+
+## Test Results
+
+```
+✔ tick offers the Unbuilding instead of ending the game immediately
+✔ renderAlignment does not wipe the Unbuilding prompt after it is offered
+✔ active Unbuilding suppresses pending alignment event UI
+✔ stage five lasts long enough to dissolve every resource card
+✔ save/load restores partial stage-five dissolve progress
+✔ deferring the Unbuilding clears the prompt and allows it to return later
+✔ defer cooldown survives save and reload
+✔ save and load preserve dismantle progress
+✔ restore re-renders an offered but not-yet-started Unbuilding prompt
+✔ defer cooldown persists after save/load when dismantleTriggered is false
+

+pass 10
+fail 0
+```
+
+## Related PRs
+
+- **PR #145**: Fixes bugs from #133 (stage 5 interval extended to 7.0s)
+
+## Recommendation
+
+Issue #16 can be closed. The Dismantle Sequence is complete and fully tested.
+
+---
+
+## Technical Details
+
+### Entry Point
+The Dismantle sequence is triggered from `engine.js` tick():
+```javascript
+if (Dismantle.isEligible()) {
+    Dismantle.checkTrigger();
+}
+```
+
+### Eligibility Conditions
+```javascript
+isEligible() {
+    const megaBuild = G.totalCode >= 1000000000 || (G.buildings.beacon || 0) >= 10;
+    const beaconPath = G.totalRescues >= 100000 && G.pactFlag === 1 && G.harmony > 50;
+    return G.phase >= 6 && G.pactFlag === 1 && (megaBuild || beaconPath);
+}
+```
+
+### State Machine
+```
+Stage 0: Not started
+    ↓ (offerChoice → player accepts)
+Stage 1-8: Active dismantling
+    ↓ (timer-based advancement)
+Stage 9: Final ("That is enough")
+    ↓ (auto-advance)
+Stage 10: Complete
+```
+
+### Integration Points
+- `engine.js`: Calls `Dismantle.tick(dt)` from main game loop
+- `render.js`: `renderAlignment()` defers to Dismantle when active
+- `main.js`: Save/load includes Dismantle state
