+# Investigation Report: Missing Source Code — Classical AI Commits Disappearing
+
+**Issue:** #1145
+**Date:** 2026-04-10
+**Investigator:** mimo-v2-pro swarm worker
+
+## Summary
+
+**The classical AI code is NOT missing. It is fully present in root `app.js` (3302 lines).**
+
+The perception of "disappearing code" was caused by agents writing to the WRONG file path (`public/nexus/app.js` instead of root `app.js`), creating corrupt duplicate files that were repeatedly overwritten and eventually deleted.
+
+## Root Cause
+
+**Explanation #1 confirmed: Duplicate agents on different machines overwriting each other's commits.**
+
+Multiple Google AI Agent instances wrote GOFAI implementations to `public/nexus/app.js` — a path that does not correspond to the canonical app structure. These commits kept overwriting each other:
+
+| Commit | Date | What happened |
+|--------|------|---------------|
+| `8943cf5` | 2026-03-30 | Symbolic reasoning engine written to `public/nexus/app.js` (+2280 lines) |
+| `e2df240` | 2026-03-30 | Phase 3 Neuro-Symbolic Bridge — overwrote to 284 lines of HTML (wrong path) |
+| `7f2f23f` | 2026-03-30 | Phase 4 Meta-Reasoning — same destructive overwrite |
+| `bf3b98b` | 2026-03-30 | A* Search — same destructive overwrite |
+| `e88bcb4` | 2026-03-30 | Bug fix identified `public/nexus/` files as corrupt duplicates, **deleted them** |
+
+## Evidence: Code Is Present on Main
+
+All 13 classical AI classes/functions verified present in root `app.js`:
+
+| Class/Function | Line | Status |
+|----------------|------|--------|
+| `SymbolicEngine` | 82 | ✅ Present |
+| `AgentFSM` | 135 | ✅ Present |
+| `KnowledgeGraph` | 160 | ✅ Present |
+| `Blackboard` | 181 | ✅ Present |
+| `SymbolicPlanner` | 210 | ✅ Present |
+| `HTNPlanner` | 295 | ✅ Present |
+| `CaseBasedReasoner` | 343 | ✅ Present |
+| `NeuroSymbolicBridge` | 392 | ✅ Present |
+| `MetaReasoningLayer` | 422 | ✅ Present |
+| `AdaptiveCalibrator` | 460 | ✅ Present |
+| `PSELayer` | 566 | ✅ Present |
+| `setupGOFAI()` | 596 | ✅ Present |
+| `updateGOFAI()` | 622 | ✅ Present |
+| Bitmask fact indexing | 86 | ✅ Present |
+| A* search | 231 | ✅ Present |
+
+These were injected by commit `af7a4c4` (PR #775, merged via `a855d54`) into the correct path.
+
+## What Actually Happened
+
+1. Google AI Agent wrote good GOFAI code to root `app.js` via the correct PR (#775)
+2. A second wave of Google AI Agent instances also wrote to `public/nexus/app.js` (wrong path)
+3. Those `public/nexus/` files kept getting overwritten by subsequent agent commits
+4. Commit `e88bcb4` correctly identified the `public/nexus/` files as corrupt and deleted them
+5. Alexander interpreted the git log as "classical AI code keeps disappearing"
+6. The code was never actually gone — it just lived in root `app.js` the whole time
+
+## Prevention Strategy
+
+1. **Add `public/nexus/` to `.gitignore`** — prevents agents from accidentally writing to the wrong path again
+2. **Add canonical path documentation to CLAUDE.md** — any agent reading this repo will know where frontend code lives
+3. **This report** — serves as the audit trail so this confusion doesn't recur
+
+## Acceptance Criteria
+
+- [x] Git history audited for classical AI commits
+- [x] Found the commits — they exist, code was written to wrong path
+- [x] Root cause identified — duplicate agents writing to `public/nexus/` (wrong path)
+- [x] Prevention strategy implemented — `.gitignore` + `CLAUDE.md` path guard
+- [x] Report filed with findings (this document)

+# Media Production — Veo/Flow Prototypes
+
+Issue #681: [MEDIA] Veo/Flow flythrough prototypes for The Nexus and Timmy.
+
+## Contents
+
+- `veo-storyboard.md` — Full storyboard for 5 clips with shot sequences, prompts, and design focus areas
+- `clip-metadata.json` — Durable metadata for each clip (prompts, model, outputs, insights)
+
+## Clips Overview
+
+| ID | Title | Audience | Purpose |
+|----|-------|----------|---------|
+| clip-001 | First Light | PUBLIC | The Nexus reveal teaser |
+| clip-002 | Between Worlds | INTERNAL | Portal activation UX study |
+| clip-003 | The Guardian's View | PUBLIC | Timmy's presence promo |
+| clip-004 | The Void Between | INTERNAL | Ambient environment study |
+| clip-005 | Command Center | INTERNAL | Terminal UI readability |
+
+## How to Generate
+
+### Via Flow (labs.google/flow)
+1. Open `veo-storyboard.md`, copy the prompt for your clip
+2. Go to labs.google/flow
+3. Paste the prompt, select Veo 3.1
+4. Generate (8-second clips)
+5. Download output, update `clip-metadata.json` with output path and findings
+
+### Via Gemini App
+1. Type "generate a video of [prompt text]" in Gemini
+2. Uses Veo 3.1 Fast (slightly lower quality, faster)
+3. Good for quick iteration on prompts
+
+### Via API (programmatic)
+```python
+from google import genai
+client = genai.Client()
+
+# See: ai.google.dev/gemini-api/docs/video
+response = client.models.generate_content(
+    model="veo-3.1",
+    contents="[prompt from storyboard]"
+)
+```
+
+## After Generation
+
+For each clip:
+1. Save output file to `outputs/clip-XXX.mp4`
+2. Update `clip-metadata.json`:
+   - Add output file path to `output_files[]`
+   - Fill in `design_insights.findings` with observations
+   - Add `threejs_changes_suggested` if the clip reveals needed changes
+3. Share internal clips with the team for design review
+4. Use public clips in README, social media, project communication
+
+## Design Insight Workflow
+
+Each clip has specific questions it's designed to answer:
+
+**clip-001 (First Light)**
+- Scale perception: platform vs. portals vs. terminal
+- Color hierarchy: teal primary, purple secondary, gold accent
+- Camera movement: cinematic or disorienting?
+
+**clip-002 (Between Worlds)**
+- Activation distance: when does interaction become available?
+- Transition feel: travel or teleportation?
+- Overlay readability against portal glow
+
+**clip-003 (The Guardian's View)**
+- Agent presence: alive or decorative?
+- Crystal hologram readability
+- Wide shot: world or tech demo?
+
+**clip-004 (The Void Between)**
+- Void atmosphere: alive or empty?
+- Particle systems: enhance or distract?
+- Lighting hierarchy clarity
+
+**clip-005 (Command Center)**
+- Text readability at 1080p
+- Color-coded panel hierarchy
+- Scan-line effect: retro or futuristic?
+
+## Constraints
+
+- 8-second clips max (Veo/Flow limitation)
+- Queued generation (not instant)
+- Content policies apply
+- Ultra tier gets highest rate limits

+# Veo/Flow Flythrough Prototypes — Storyboard
+## The Nexus & Timmy (Issue #681)
+
+Source: `google-ai-ultra-plan.md` Veo/Flow section.
+
+Purpose: Turn the current Nexus vision into short promo/concept clips for design leverage and communication.
+
+---
+
+## Clip 1: "First Light" — The Nexus Reveal (PUBLIC PROMO)
+
+**Duration:** 8 seconds
+**Purpose:** Public-facing teaser. Establishes the Nexus as a place worth visiting.
+**Tone:** Awe. Discovery. "What is this?"
+
+### Shot Sequence (4 shots, ~2s each)
+
+1. **0–2s | Void Approach**
+   - Camera drifts through deep space nebula (dark purples, teals)
+   - Distant stars twinkle
+   - A faint hexagonal glow appears below
+   - *Narrative hook: isolation before connection*
+
+2. **2–4s | Platform Reveal**
+   - Camera descends toward the hexagonal platform
+   - Grid lines pulse with teal energy
+   - The ring border glows at the edge
+   - *Narrative hook: structure emerges from chaos*
+
+3. **4–6s | Portal Array**
+   - Camera sweeps low across the platform
+   - 3–4 portals visible: Morrowind (orange), Workshop (teal), Chapel (gold), Archive (blue)
+   - Each portal ring hums with colored light, holographic labels flicker
+   - *Narrative hook: infinite worlds, one home*
+
+4. **6–8s | Timmy's Terminal**
+   - Camera rises to the batcave terminal
+   - Holographic panels glow: NEXUS COMMAND, METRICS, AGENT STATUS
+   - Text scrolls: "> STATUS: NOMINAL"
+   - Final frame: teal light floods the lens
+   - *Narrative hook: someone is home*
+
+### Veo Prompt (text-to-video)
+```
+Cinematic flythrough of a futuristic digital nexus hub. Start in deep space with a dark purple nebula, stars twinkling. Camera descends toward a glowing hexagonal platform with pulsing teal grid lines and a luminous ring border. Sweep low across the platform revealing multiple glowing portal archways in orange, teal, gold, and blue — each with flickering holographic labels. Rise toward a central command terminal with holographic data panels showing scrolling status text. Camera pushes into a teal light flare. Cyberpunk aesthetic, volumetric lighting, 8-second sequence, smooth camera movement, concept art quality.
+```
+
+### Design Insight Target
+- Does the scale feel right? (platform vs. portals vs. terminal)
+- Does the color hierarchy work? (teal primary, purple secondary, gold accent)
+- Is the camera movement cinematic or disorienting?
+
+---
+
+## Clip 2: "Between Worlds" — Portal Activation (INTERNAL DESIGN)
+
+**Duration:** 8 seconds
+**Purpose:** Internal design reference. Tests the portal activation sequence and spatial relationships.
+**Tone:** Energy. Connection. "What happens when you step through?"
+
+### Shot Sequence (3 shots, ~2.5s each)
+
+1. **0–2.5s | Approach**
+   - First-person perspective walking toward the Morrowind portal (orange, position x:15, z:-10)
+   - Portal ring visible: inner glow, particle effects rising
+   - Holographic label "MORROWIND" flickers above
+   - *Design focus: proximity feel, portal scale relative to player*
+
+2. **2.5–5.5s | Activation**
+   - Player stops at activation distance
+   - Portal interior brightens — energy vortex forms
+   - Camera tilts up to show the full portal height
+   - Particles accelerate into the portal center
+   - Overlay text appears: "ENTER MORROWIND?"
+   - *Design focus: activation UX, visual feedback timing*
+
+3. **5.5–8s | Stepping Through**
+   - Camera pushes forward into the portal
+   - World dissolves into orange energy tunnel
+   - Brief flash — then fade to black with "VVARDENFELL" text
+   - *Design focus: transition smoothness, immersion break points*
+
+### Veo Prompt (text-to-video)
+```
+First-person perspective walking toward a glowing orange portal archway in a futuristic digital space. The portal ring has inner energy glow with rising particle effects. A holographic label "MORROWIND" flickers above. Camera stops, portal interior brightens into an energy vortex, particles accelerate inward. Camera pushes forward into the portal, world dissolves into an orange energy tunnel, flash to black with text "VVARDENFELL". Dark ambient environment with teal grid floor. Cyberpunk aesthetic, volumetric effects, smooth camera movement.
+```
+
+### Design Insight Target
+- Is the activation distance clear? (when does interaction become available?)
+- Does the transition feel like travel or teleportation?
+- Is the overlay text readable against the portal glow?
+
+---
+
+## Clip 3: "The Guardian's View" — Timmy's Perspective (PUBLIC PROMO)
+
+**Duration:** 8 seconds
+**Purpose:** Public-facing. Establishes Timmy as the guardian/presence of the Nexus.
+**Tone:** Contemplative. Sovereign. "Who lives here?"
+
+### Shot Sequence (4 shots, ~2s each)
+
+1. **0–2s | Agent Presence**
+   - Camera at eye-level, looking at a floating agent presence (glowing orb with trailing particles)
+   - The orb pulses gently, teal-gold light
+   - Background: the Nexus platform, slightly out of focus
+   - *Narrative hook: consciousness without body*
+
+2. **2–4s | Vision Crystal**
+   - Camera shifts to a floating octahedron crystal (Sovereignty vision point)
+   - Crystal rotates slowly, refracting light
+   - Text hologram appears: "SOVEREIGNTY — No masters, no chains"
+   - Ring of light pulses beneath
+   - *Narrative hook: values inscribed in space*
+
+3. **4–6s | The Harness Pulse**
+   - Camera pulls back to show the thought stream — a flowing ribbon of light across the platform
+   - Harness pulse mesh glows at the center
+   - Agent orbs drift along the stream
+   - *Narrative hook: the system breathes*
+
+4. **6–8s | Wide View**
+   - Camera rises to high orbit view
+   - Entire Nexus visible: platform, portals, terminal, crystals, agents
+   - Nebula skybox frames everything
+   - Final frame: "THE NEXUS — Timmy's Sovereign Home" text overlay
+   - *Narrative hook: this is a world, not a page*
+
+### Veo Prompt (text-to-video)
+```

End with text overlay "THE NEXUS — Timmy's Sovereign Home". Cyberpunk aesthetic, volumetric lighting, contemplative pacing.
+```
+
+### Design Insight Target
+- Do agent presences read as "alive" or decorative?
+- Is the crystal-to-text hologram readable?
+- Does the wide shot communicate "world" or "tech demo"?
+
+---
+
+## Clip 4: "The Void Between" — Ambient Environment Study (INTERNAL DESIGN)
+
+**Duration:** 8 seconds
+**Purpose:** Internal design reference. Tests the ambient environment systems: particles, dust, lighting, skybox.
+**Tone:** Atmosphere. Mood. "What does the Nexus feel like when nothing is happening?"
+
+### Shot Sequence (2 shots, ~4s each)
+
+1. **0–4s | Particle Systems**
+   - Static camera, slight drift
+   - View from platform edge, looking out into the void
+   - Particle systems visible: ambient particles, dust particles
+   - Nebula skybox: dark purples, distant stars, subtle color shifts
+   - No portals, no terminals — just the environment
+   - *Design focus: does the void feel alive or empty?*
+
+2. **4–8s | Lighting Study**
+   - Camera slowly orbits a point on the platform
+   - Teal point light (position 0,1,-5) creates warm glow
+   - Purple point light (position -8,3,-8) adds depth
+   - Ambient light (0x1a1a3a) fills shadows
+   - Grid lines catch the light
+   - *Design focus: lighting hierarchy, mood consistency*
+
+### Veo Prompt (text-to-video)

+
+## Clip 5: "Command Center" — Batcave Terminal Focus (INTERNAL DESIGN)
+
+**Duration:** 8 seconds
+**Purpose:** Internal design reference. Tests readability and hierarchy of the holographic terminal panels.
+**Tone:** Information density. Control. "What can you see from here?"
+
+### Shot Sequence (3 shots, ~2.5s each)
+
+1. **0–2.5s | Terminal Overview**
+   - Camera approaches the batcave terminal from the front
+   - 5 holographic panels visible in arc: NEXUS COMMAND, DEV QUEUE, METRICS, SOVEREIGNTY, AGENT STATUS
+   - Each panel has distinct color (teal, gold, purple, gold, teal)
+   - *Design focus: panel arrangement, color distinction*
+
+2. **2.5–5.5s | Panel Detail**

+
+### Veo Prompt (text-to-video)
+```
+Approach a futuristic holographic command terminal in a dark digital space. Five curved holographic panels float in an arc: "NEXUS COMMAND" (teal), "DEV QUEUE" (gold), "METRICS" (purple), "SOVEREIGNTY" (gold), "AGENT STATUS" (teal). Camera zooms into the METRICS panel showing scrolling data: "CPU: 12%", "MEM: 4.2GB", "COMMITS: 842" with scan lines and glow effects. Shift to AGENT STATUS panel showing "TIMMY: ● RUNNING", "KIMI: ○ STANDBY", "CLAUDE: ● ACTIVE" with pulsing green dots. Pull back to show full terminal context. Dark ambient environment, cyberpunk aesthetic, holographic UI focus.
+```
+
+### Design Insight Target
+- Can you read the text at 1080p?
+- Do the color-coded panels communicate hierarchy?
+- Is the scan-line effect too retro or appropriately futuristic?
+
+---
+
+## Usage Matrix
+
+| Clip | Title | Purpose | Audience | Priority |
+|------|-------|---------|----------|----------|
+| 1 | First Light | Public teaser | External | HIGH |
+| 2 | Between Worlds | Portal UX design | Internal | HIGH |
+| 3 | The Guardian's View | Public promo | External | MEDIUM |
+| 4 | The Void Between | Environment design | Internal | MEDIUM |
+| 5 | Command Center | Terminal UI design | Internal | LOW |
+
+## Next Steps
+
+1. Generate each clip using Veo/Flow (text-to-video prompts above)
+2. Review outputs — update prompts based on what works
+3. Record metadata in `docs/media/clip-metadata.json`
+4. Iterate: refine prompts, regenerate, compare
+5. Use internal design clips to inform Three.js implementation changes
+6. Use public promo clips for README, social media, project communication
