fix: resolve #192 — move dead code to docs/reference, fix GENOME.md

- game/npc-logic.js → docs/reference/npc-logic-prototype.js (ES module, never imported)
- scripts/guardrails.js → docs/reference/guardrails-prototype.js (HP/MP validation, wrong game)
- Updated GENOME.md architecture diagram to reflect actual file structure
- Updated DEAD_CODE_AUDIT to mark these as resolved
- Corrected JS line counts (6,033 across 11 files)
- Removed empty game/ directory

The actual CI scripts (guardrails.sh, smoke.mjs) remain active in scripts/.

+> Codebase analysis generated 2026-04-13. Sovereign AI idle game — browser-based.
+
+## Project Overview
+
+The Beacon is a browser-based idle/incremental game inspired by Universal Paperclips, themed around the Timmy Foundation's real journey building sovereign AI. The core divergence from Paperclips: the goal is not maximization — it is faithfulness. "Can you grow powerful without losing your purpose?"
+
+Static HTML/JS — no build step, no dependencies, no framework. Open `index.html` in any browser.
+
+**6,033 lines of JavaScript** across 11 files. **1 HTML file** with embedded CSS (~300 lines). **3 test files** (2 Node.js, 1 Python).
+
+## Architecture

+    +-- docs/reference/guardrails-prototype.js   Stat validation prototype
+```
+
+## Entry Points
+
+### index.html
+The single entry point. Loads all JS files, contains all HTML structure and inline CSS. Open directly in browser — no server required.
+
+### js/main.js — Initialization
+`initGame()` sets initial state, starts the 10Hz tick loop (`setInterval(tick, 100)`), triggers tutorial for new games, loads saved games, starts ambient sound.
+
+### js/engine.js — Game Loop
+The `tick()` function runs every 100ms. Each tick:
+1. Accumulate resources (code, compute, knowledge, users, impact, rescues, ops, trust, creativity, harmony)
+2. Process buildings and their rate multipliers
+3. Check phase transitions (Phase 1→6 based on total code thresholds)
+4. Trigger random events (corruption events, alignment events, wizard events)
+5. Update boosts, debuffs, and cooldowns
+6. Call `render()` to update UI
+
+## Data Flow
+
+```
+User clicks "WRITE CODE" / presses SPACE
+    |
+    v
+G.code += 1 (or more with auto-clickers, combos, boosts)
+    |
+    v
+tick() accumulates all passive rates from buildings
+    |
+    v
+updateRates() recalculates based on:
+  - Building counts × base rates × boost multipliers
+  - Harmony (Timmy's multiplier, Pact drain/gain)
+  - Bilbo randomness (burst/vanish per tick)
+  - Active debuffs
+    |
+    v
+Phase check: totalCode thresholds → unlock new content
+    |
+    v
+Event roll: 2% per tick → corruption/alignment/wizard events
+    |
+    v
+render() updates DOM
+```
+
+## Key Abstractions
+
+### Resources (10 types)
+- **code** — primary resource, generated by clicking and AutoCoders
+- **compute** — powers training and inference
+- **knowledge** — from research, unlocks projects
+- **users** — from API deployment, drives ops and impact
+- **impact** — from users × agents, drives rescues
+- **rescues** — the endgame metric (people helped in crisis)
+- **ops** — operational currency, from users
+- **trust** — hard constraint, earned/lost by decisions
+- **creativity** — from Bilbo and community
+- **harmony** — fleet health, affects Timmy's multiplier
+
+### Buildings (defined in js/data.js as BDEF array)
+Each building has: id, name, description, cost formula, rates, unlock conditions. Buildings include:
+- AutoCode Generator, Home Server, Training Lab, API Endpoint
+- Wizard agents: Bezalel, Allegro, Ezra, Timmy, Fenrir, Bilbo
+- Infrastructure: Lazarus Pit, MemPalace, Forge CI, Mesh Nodes
+
+### Projects (in js/data.js)
+One-time purchases that unlock features, buildings, or multipliers. Organized in phases. Projects require specific resource thresholds and prerequisites.
+
+### Phases (6 total)
+1. The First Line (click → autocoder)
+2. Local Inference (server → training → first agent)
+3. Deployment (API → users → trust mechanic)
+4. The Network (open source → community)
+5. Sovereign Intelligence (self-improvement → The Pact)
+6. The Beacon (mesh → rescues → endings)
+
+### Events (corruption, alignment, wizard)
+Random events at 2% per tick. Include:
+- CI Runner Stuck, Ezra Offline, Unreviewed Merge
+- The Drift (alignment events offering shortcuts)
+- Bilbo Vanished, Community Drama
+- Boss encounters (combat.js)
+
+### Endings (4 types)
+- The Empty Room (high impact, low trust, no Pact)
+- The Platform (high impact, medium trust, no Pact)
+- The Beacon (high rescues, high trust, Pact active, harmony > 50)
+- The Drift (too many shortcuts accepted)
+
+## API Surface
+
+### Save/Load (localStorage)
+- `saveGame()` — serializes G state to localStorage
+- `loadGame()` — deserializes from localStorage
+- `exportGame()` — JSON download of save state
+- `importGame()` — JSON upload to restore state
+
+### No external APIs
+The game is entirely client-side. No network calls, no analytics, no tracking.
+
+### Audio (Web Audio API)
+- `Sound.startAmbient()` — oscillator-based ambient drone
+- `Sound.updateAmbientPhase(phase)` — frequency shifts with game phase
+- Sound effects for clicks, upgrades, events
+
+## Test Coverage
+
+### Existing Tests
+- `tests/test_reckoning_projects.py` (148 lines) — Python test for reckoning project data validation
+- `tests/dismantle.test.cjs` — Node.js test for dismantle sequence
+
+### Coverage Gaps
+- **No tests for core engine logic** (tick, resource accumulation, rate calculation)
+- **No tests for event system** (event triggers, probability, effects)
+- **No tests for phase transitions** (threshold checks, unlock conditions)
+- **No tests for save/load** (serialization roundtrip, corruption handling)
+- **No tests for building cost scaling** (exponential cost formulas)
+- **No tests for harmony/drift mechanics** (the core gameplay differentiator)
+- **No tests for endings** (condition checks, state transitions)
+
+### Critical paths that need tests:
+1. **Resource accumulation**: tick() correctly multiplies rates by building counts and boosts
+2. **Phase transitions**: totalCode thresholds unlock correct content
+3. **Save/load roundtrip**: localStorage serialization preserves full game state
+4. **Event probability**: 2% per tick produces expected distribution
+5. **Harmony calculation**: wizard drain vs. Pact/NightlyWatch/MemPalace gains
+6. **Ending conditions**: each ending triggers on correct state
+
+## Security Considerations
+
+- **No authentication**: game is fully client-side, no user accounts
+- **localStorage manipulation**: players can edit save data to cheat (acceptable for single-player idle game)
+- **No XSS risk**: all DOM updates use textContent or innerHTML with game-controlled data only
+- **No external dependencies**: zero attack surface from third-party code
+- **Web Audio autoplay policy**: sound starts on first user interaction (compliant)
+
+## Design Decisions
+
+- **No build step**: intentional. Open index.html, play. No npm, no webpack, no framework.
+- **10Hz tick rate**: 100ms interval balances responsiveness with CPU usage
+- **Global state object (G)**: mirrors Paperclips' pattern. Simple, flat, serializable.
+- **Inline CSS in HTML**: keeps the project to 2 files minimum (index.html + JS)
+- **Progressive phase unlocks**: prevents information overload, teaches mechanics gradually

-### Potentially Unimported Files
+### Dead Code — Resolved (2026-04-15, Issue #192)
 
-The following files were added by recent PRs but may not be imported
-by the main game runtime (`js/main.js` → `js/engine.js`):
+The following files were confirmed dead code — never imported by any runtime module.
+They have been moved to `docs/reference/` as prototype reference code.
 
-| File | Added By | Lines | Status |
-|------|----------|-------|--------|
-| `game/npc-logic.js` | PR #79 (GOFAI NPC State Machine) | ~150 | **Verify import** |
-| `scripts/guardrails.js` | PR #80 (GOFAI Symbolic Guardrails) | ~120 | **Verify import** |
-
-**Action:** Check if `js/main.js` or `js/engine.js` imports from `game/` or `scripts/`.
-If not, these files are dead code and should either be:
-1. Imported and wired into the game loop, or
-2. Moved to `docs/` as reference implementations
+| File | Original | Resolution |
+|------|----------|------------|
+| `game/npc-logic.js` | PR #79 (GOFAI NPC State Machine) | **Moved to `docs/reference/npc-logic-prototype.js`** — ES module using `export default`, incompatible with the global-script loading pattern. Concept (NPC state machine) is sound but not wired into any game system. |
+| `scripts/guardrails.js` | PR #80 (GOFAI Symbolic Guardrails) | **Moved to `docs/reference/guardrails-prototype.js`** — validates HP/MP/stats concepts that don't exist in The Beacon's resource system. The `scripts/guardrails.sh` (bash CI script) remains active. |

+## CRITICAL BUGS
+
+### BUG-01: Duplicate `const` declarations across data.js and engine.js
+**Severity:** CRITICAL (game-breaking)
+**Files:** `js/data.js`, `js/engine.js`
+**Description:** Both files declare the same global constants:
+- `const CONFIG` (both files)
+- `const G` (both files)
+- `const PHASES` (both files)
+- `const BDEF` (both files)
+- `const PDEFS` (both files)
+
+Script load order in index.html: data.js loads first, then engine.js.
+Since both use `const`, the browser will throw `SyntaxError: redeclaration of const CONFIG` (Firefox) or `Identifier 'CONFIG' has already been declared` (Chrome) when engine.js loads. **The game cannot start.**
+
+**Fix:** Remove these declarations from one of the two files. Recommend keeping definitions in `data.js` and having `engine.js` only contain logic functions (tick, updateRates, etc.).
+
+### BUG-02: BDEF array has extra `},` creating invalid array element
+**Severity:** CRITICAL
+**File:** `js/engine.js` lines 357-358
+**Description:**
+```javascript
+    },  // closes memPalace object
+    },  // <-- EXTRA: this becomes `undefined` or invalid array element
+    {
+        id: 'harvesterDrone', ...
+```
+The `},` on line 358 is a stray empty element. After `memPalace`'s closing `},` there is another `},` which creates an invalid or empty slot in the BDEF array. This breaks the drone buildings that follow (harvesterDrone, wireDrone, droneFactory).
+
+**Fix:** Remove the extra `},` on line 358.
+
+### BUG-03: Duplicate project definitions — `p_the_pact` and `p_the_pact_early`
+**Severity:** HIGH
+**Files:** `js/data.js` lines 612-619, lines 756-770
+**Description:** Two Pact projects exist:
+1. `p_the_pact` — costs 100 trust, triggers at totalImpact >= 10000, trust >= 75. Grants `impactBoost *= 3`.
+2. `p_the_pact_early` — costs 10 trust, triggers at deployFlag === 1, trust >= 5. Grants `codeBoost *= 0.8, computeBoost *= 0.8, userBoost *= 0.9, impactBoost *= 1.5`.
+
+Both set `G.pactFlag = 1`. If the player buys the early version, the late-game version's trigger (`G.pactFlag !== 1`) is never met, so it never appears. This is likely intentional design (choose your path), BUT:
+- The early Pact REDUCES boosts (0.8x code/compute) as a tradeoff. A new player may not understand this penalty.
+- If the player somehow buys BOTH (race condition or save manipulation), `pactFlag` is set twice and `impactBoost` is multiplied by 3 AND the early penalties apply.
+
+**Fix:** Add a guard in `p_the_pact` trigger: `&& G.pactFlag !== 1`.
+
+---
+
+## FUNCTIONAL BUGS
+
+### BUG-04: Resource key mismatch — `user` vs `users`
+**Severity:** MEDIUM
+**File:** `js/engine.js` lines 15, `js/data.js` building definitions
+**Description:** The game state uses `G.users` as the resource name, but building rate definitions use `user` as the key:
+```javascript
+rates: { user: 10 }  // api building
+rates: { user: 50, impact: 2 }  // fineTuner
+```
+In `updateRates()`, the code checks `resource === 'user'` and adds to `G.userRate`. This works for rate calculation, but the naming mismatch is confusing and could cause bugs if someone tries to reference `G.user` (which is `undefined`).
+
+**Fix:** Standardize on one key name. Either rename the resource to `user` everywhere or change building rate keys to `users`.
+
+### BUG-05: Bilbo randomness recalculated every tick (10Hz)
+**Severity:** MEDIUM
+**File:** `js/engine.js` lines 81-87
+**Description:**
+```javascript
+if (G.buildings.bilbo > 0 && Math.random() < CONFIG.BILBO_BURST_CHANCE) {
+    G.creativityRate += 50 * G.buildings.bilbo;
+}
+if (G.buildings.bilbo > 0 && Math.random() < CONFIG.BILBO_VANISH_CHANCE) {
+    G.creativityRate = 0;
+}
+```
+`updateRates()` is called every tick via the render loop. Each tick, Bilbo has independent 10% burst and 5% vanish chances. Over 10 seconds (100 ticks):
+- Probability of at least one burst: `1 - 0.9^100 = 99.997%`
+- Probability of at least one vanish: `1 - 0.95^100 = 99.4%`
+
+The vanish check runs AFTER the burst check, so a burst can be immediately overwritten by vanish on the same tick. Effectively, Bilbo's "wildcard" behavior is almost guaranteed every second, making it predictable rather than surprising.
+
+**Fix:** Move Bilbo's random effects to a separate timer-based system (e.g., roll once per 10-30 seconds) or use a tick counter.
+
+### BUG-06: Memory leak toast says "trust draining" but resolves with code
+**Severity:** LOW (cosmetic/misleading)
+**File:** `js/engine.js` line 660
+**Description:**
+```javascript
+showToast('Memory Leak — trust draining', 'event');
+```
+But the actual resolve cost is:
+```javascript
+resolveCost: { resource: 'ops', amount: 100 }
+```
+The toast says "trust draining" but the event drains compute (70% reduction) and ops, and costs 100 ops to resolve. The toast message is misleading.
+
+**Fix:** Change toast to `'Memory Leak — compute draining'`.
+
+### BUG-07: `phase-transition` overlay element missing from HTML
+**Severity:** LOW (visual feature broken)
+**File:** `js/engine.js` line 237, `index.html`
+**Description:** `showPhaseTransition()` looks for `document.getElementById('phase-transition')` but this element does not exist in `index.html`. Phase transitions will silently fail — no celebratory overlay appears.
+
+**Fix:** Add the phase-transition overlay div to index.html or create it dynamically in `showPhaseTransition()`.
+
+### BUG-08: `renderResources` null reference risk on rescues
+**Severity:** LOW
+**File:** `js/engine.js` line 954
+**Description:**
+```javascript
+const rescuesRes = document.getElementById('r-rescues');
+if (rescuesRes) {
+    rescuesRes.closest('.res').style.display = ...
+```
+If the rescues `.res` container is missing or the DOM structure is different, `closest('.res')` could return `null` and throw. In practice the HTML structure supports this, but no null check on `closest()`.
+
+**Fix:** Add null check: `const container = rescuesRes.closest('.res'); if (container) container.style.display = ...`
+
+---
+
+## ACCESSIBILITY ISSUES
+
+### BUG-09: Mute and Contrast buttons referenced but not in HTML
+**Severity:** MEDIUM (accessibility)
+**Files:** `js/main.js` lines 76-93, `index.html`
+**Description:** `toggleMute()` looks for `#mute-btn` and `toggleContrast()` looks for `#contrast-btn`. Neither button exists in `index.html`. The keyboard shortcuts M (mute) and C (contrast) will silently do nothing.
+
+**Fix:** Add mute and contrast buttons to the HTML header or action panel.
+
+### BUG-10: Missing `role="status"` on resource display updates
+**Severity:** LOW (screen readers)
+**File:** `index.html` line 117
+**Description:** The resources div has `aria-live="polite"` which is good, but rapid updates (10Hz) will flood screen readers with announcements. Consider throttling aria-live updates to once per second.
+
+### BUG-11: Tutorial overlay traps focus
+**Severity:** MEDIUM (keyboard accessibility)
+**File:** `js/tutorial.js`
+**Description:** The tutorial overlay doesn't implement focus trapping. Screen reader users can tab behind the overlay. Also, the overlay doesn't set `role="dialog"` or `aria-modal="true"`.
+
+**Fix:** Add `role="dialog"`, `aria-modal="true"` to the tutorial overlay, and implement focus trapping.
+
+---
+
+## UI/UX ISSUES
+
+### BUG-12: Harmony tooltip shows rate ×10
+**Severity:** LOW (confusing)
+**File:** `js/engine.js` line 972
+**Description:
+```javascript
+lines.push(`${b.label}: ${b.value >= 0 ? '+' : ''}${(b.value * 10).toFixed(1)}/s`);
+```
+The harmony breakdown tooltip multiplies by 10, presumably to convert from per-tick (0.1s) to per-second. But `b.value` is already the per-second rate (set from `CONFIG.HARMONY_DRAIN_PER_WIZARD` etc. which are per-second values used in `G.harmonyRate`). The ×10 multiplication makes the tooltip display 10× the actual rate.
+
+**Fix:** Remove the `* 10` multiplier: `b.value.toFixed(1)` instead of `(b.value * 10).toFixed(1)`.
+
+### BUG-13: Auto-type increments totalClicks
+**Severity:** LOW (statistics inflation)
+**File:** `js/engine.js` line 783
+**Description:**
+```javascript
+function autoType() {
+    G.code += amount;
+    G.totalCode += amount;
+    G.totalClicks++;  // <-- inflates click count
+}
+```
+Auto-type fires automatically from buildings but increments the "Clicks" stat, making it meaningless as a manual-click counter.
+
+**Fix:** Remove `G.totalClicks++` from `autoType()`.
+
+### BUG-14: Spelling: "AutoCod" missing 'e'
+**Severity:** TRIVIAL (typo)
+**File:** `js/data.js` line 775
+**Description:**
+```javascript
+{ flag: 1, msg: "AutoCod available" },
+```
+Should be "AutoCoder".
+
+**Fix:** Change to `"AutoCoder available"`.
+
+### BUG-15: No negative resource protection
+**Severity:** LOW
+**Files:** `js/engine.js`, `js/utils.js`
+**Description:** Resources can go negative in several scenarios:
+- `ops` can go negative from Fenrir buildings (`ops: -1` rate)
+- Spending resources doesn't check for negative results (only checks affordability before spending)
+- Negative resources display with a minus sign via `fmt()` but can trigger weird behavior in threshold checks
+
+**Fix:** Add `G.ops = Math.max(0, G.ops)` in the tick function, or clamp all resources after production.
+
+---
+
+## BALANCE ISSUES
+
+### BAL-01: Drone buildings have absurdly high rates
+**Severity:** MEDIUM
+**File:** `js/engine.js` lines 362-382
+**Description:** The three drone buildings have rates in the millions/billions:
+- harvesterDrone: `code: 26,180,339` (≈26M per drone per second)
+- wireDrone: `compute: 16,180,339` (≈16M per drone per second)
+- droneFactory: `code: 161,803,398`, `compute: 100,000,000`
+
+These appear to use golden ratio values as literal rates. One harvester drone produces more code per second than all other buildings combined by several orders of magnitude. This completely breaks game balance once unlocked.
+
+**Fix:** Scale down by ~10000x or redesign to use golden ratio as a multiplier rather than absolute rate.
+
+### BAL-02: Community building costs 25,000 trust
+**Severity:** MEDIUM
+**File:** `js/data.js` line 243
+**Description:**
+```javascript
+baseCost: { trust: 25000 }, costMult: 1.15,
+```
+Trust generation is slow (typically 0.5-10/sec). Accumulating 25,000 trust would take 40+ minutes of dedicated trust-building. Meanwhile the building produces code (100/s) and users (30/s), which is modest compared to the trust investment.
+
+**Fix:** Reduce trust cost to 2,500 or increase the building's output significantly.
+
+### BAL-03: "Request More Compute" repeatable project can drain trust
+**Severity:** LOW
+**File:** `js/data.js` lines 376-387
+**Description:** `p_wire_budget` costs 1 trust and also subtracts 1 trust in its effect:
+```javascript
+cost: { trust: 1 },
+effect: () => { G.trust -= 1; G.compute += 100 + ...; }
+```
+This means each use costs 2 trust total. The trigger (`G.compute < 1`) fires whenever compute is depleted. If a player has no compute generation and clicks this repeatedly, they can drain trust to 0 or negative.
+
+**Fix:** Change the effect to not double-count trust. Either remove from cost or from effect.
+
+---
+
+## SAVE/LOAD ISSUES
+
+### SAV-01: Debuffs re-apply effects on load, then updateRates applies again
+**Severity:** MEDIUM
+**File:** `js/render.js` (loadGame function) lines 281-292
+**Description:** When loading a save with active debuffs, the code re-fires `evDef.effect()` which pushes a debuff with an `applyFn`. Then `updateRates()` is called, which runs each debuff's `applyFn`. Some debuffs apply permanent rate modifications in their `applyFn` (e.g., `G.codeRate *= 0.5`). If `updateRates()` was already called before debuff restoration, the rates are correct. But the order matters and could lead to double-application.
+
+Looking at the actual load sequence: `updateRates()` is NOT called before debuff restoration. Debuffs are restored, THEN `updateRates()` is called. The `applyFn`s run inside `updateRates()`, so the sequence is actually correct. However, the debuff `effect()` function also logs messages and shows toasts during load, which may confuse the player.
+
+**Fix:** Suppress logging/toasts during debuff restoration by checking `G.isLoading` (which is set to true during load).
