perf(#873 ): implement Three.js LOD and texture optimization

- Agent orbs: THREE.LOD with 3 detail levels (32/16/8 segments) - Halo geometry: reduced from 64 to 24 segments - Particle systems: LOD-aware counts (500-1500 based on tier) - Agent label texture cache: reuse textures across agents - Stats.js integration for performance monitoring - Document minimum sovereign hardware requirements Refs #873

+# Three.js LOD and Texture Audit — Issue #873
+
+## Audit Summary
+
+**Date:** 2026-04-13
+**Issue:** #873 — Three.js LOD and Texture Audit for Local Hardware
+**Target:** 60fps on base M1 Mac (8-core CPU, 7-core GPU, 8GB RAM)
+
+## Changes Made
+
+### 1. Agent LOD Implementation
+
+**Before:** All agent orbs used `SphereGeometry(0.4, 32, 32)` regardless of distance.
+**After:** Implemented `THREE.LOD` with three detail levels:
+
+| Distance | Geometry | Segments | Triangles |
+|----------|----------|----------|-----------|
+| 0-15 units | High | 32x32 | ~2,048 |
+| 15-30 units | Medium | 16x16 | ~512 |
+| 30+ units | Low | 8x8 | ~128 |
+
+**Impact:** ~75% triangle reduction for distant agents (4 agents × 3 levels).
+
+### 2. Halo Geometry Optimization
+
+**Before:** `TorusGeometry(0.6, 0.02, 16, 64)` — 64 segments
+**After:** Reduced to 24 segments (12 on low-tier)
+
+**Impact:** ~62% vertex reduction per halo.
+
+### 3. Agent Label Texture Cache
+
+**Before:** Each agent created its own CanvasTexture.
+**After:** Implemented texture cache keyed by `name_color`. Reuses textures for agents with same name/color.
+
+**Impact:** Reduced texture memory and GPU uploads.
+
+### 4. Particle System LOD
+
+| Tier | Main Particles | Dust Particles | Total |
+|------|----------------|----------------|-------|
+| High | 1,500 | 500 | 2,000 |
+| Medium | 1,000 | 300 | 1,300 |
+| Low | 500 | 150 | 650 |
+
+**Impact:** 67% particle reduction on low-tier hardware.
+
+### 5. Post-Processing Tiering
+
+| Setting | High | Medium | Low |
+|---------|------|--------|-----|
+| Bloom Strength | 0.6 | 0.35 | 0.35 |
+| Shadow Map | 2048px | 1024px | 512px |
+| Pixel Ratio | 2x | devicePR | 1x |
+
+### 6. Stats.js Integration
+
+Added `three/addons/libs/stats.module.js` for real-time performance monitoring.
+
+**Access:** `window.stats` in browser console. Shows FPS, render time, and draw calls.
+
+## Minimum Sovereign Hardware Requirements
+
+### Tier: Low (Target: 30fps)
+- **CPU:** 4+ cores (Intel i5 / Apple M1 / AMD Ryzen 3)
+- **GPU:** Integrated (Intel UHD 630 / Apple M1)
+- **RAM:** 4GB
+- **Browser:** Chrome 90+, Firefox 88+, Safari 15+
+
+### Tier: Medium (Target: 45fps)
+- **CPU:** 6+ cores (Intel i7 / Apple M1 Pro / AMD Ryzen 5)
+- **GPU:** Entry discrete (GTX 1050 / Apple M1 Pro 14-core)
+- **RAM:** 8GB
+- **Browser:** Latest versions
+
+### Tier: High (Target: 60fps)
+- **CPU:** 8+ cores (Intel i9 / Apple M1 Max / AMD Ryzen 7)
+- **GPU:** Mid-range discrete (RTX 3060 / Apple M1 Max 24-core)
+- **RAM:** 16GB
+- **Browser:** Latest versions
+
+## Performance Validation Checklist
+
+- [ ] Stats.js overlay showing 60fps with 5+ agents
+- [ ] Draw calls < 100 per frame
+- [ ] Triangle count < 500k per frame
+- [ ] Texture memory < 256MB
+- [ ] No frame spikes > 16.6ms (60fps budget)
+
+## Future Optimizations
+
+1. **Instanced Rendering:** Use `InstancedMesh` for repeated geometries (portals, runestones)
+2. **Texture Atlasing:** Combine agent label textures into single atlas
+3. **Basis/KTX2:** Compress textures with Basis Universal
+4. **WebGL2 Compute:** Offload particle updates to compute shaders
+5. **Occlusion Culling:** Implement for interior spaces

+- a local-first training ground for Timmy
+- a wizardly visualization surface for the living system

 ## Current Truth

-Current `main` does **not** ship a browser 3D world. A clean checkout contains:
+As of current `main`, this repo does **not** ship a browser 3D world.
+In plain language: current `main` does not ship a browser 3D world.

+A clean checkout of `Timmy_Foundation/the-nexus` on `main` currently contains:
 - Python heartbeat / cognition files under `nexus/`
- `server.py` — local websocket bridge
- Protocol, report, and deployment docs
- JSON config files (`portals.json`, `vision.json`)
+- `server.py`
+- protocol, report, and deployment docs
+- JSON configuration files like `portals.json` and `vision.json`

-It does **not** currently contain an active root frontend (`index.html`, `app.js`, `style.css`).
+It does **not** currently contain an active root frontend such as:
+- `index.html`
+- `app.js`
+- `style.css`
+- `package.json`
+
+Serving the repo root today shows a directory listing, not a rendered world.

 ## One Canonical 3D Repo

-`Timmy_Foundation/the-nexus` is the **only** canonical 3D repo.
+`Timmy_Foundation/the-nexus` is the only canonical 3D repo.
+In plain language: Timmy_Foundation/the-nexus is the only canonical 3D repo.

-The legacy browser app at `/Users/apayne/the-matrix` is source material for migration, not a second repo to keep evolving in parallel. Useful work from it must be audited and migrated here.
+The old local browser app at:
+- `/Users/apayne/the-matrix`

-See `LEGACY_MATRIX_AUDIT.md`.
+is legacy source material, not a second repo to keep evolving in parallel.
+Useful work from it must be audited and migrated here.

-## Why This Matters
+See:
+- `LEGACY_MATRIX_AUDIT.md`

-We do not want to lose real quality work. We also do not want to keep two drifting 3D repos alive by accident.
+## Why this matters

-The rule:
- Rescue good work from legacy Matrix
- Rebuild inside `the-nexus`
- Keep telemetry and durable truth flowing through the Hermes harness
+We do not want to lose real quality work.
+We also do not want to keep two drifting 3D repos alive by accident.

-## Active Migration Backlog
+The rule is:
+- rescue good work from legacy Matrix
+- rebuild inside `the-nexus`
+- keep telemetry and durable truth flowing through the Hermes harness
+- Hermes is the sole harness — no external gateway dependencies

-| Issue | Work |
-|-------|------|
-| #684 | Sync docs to repo truth |
-| #685 | Preserve legacy Matrix quality work |
-| #686 | Rebuild browser smoke / visual validation |
-| #687 | Restore wizardly local-first visual shell |
-| #672 | Rebuild portal stack (Timmy → Reflex → Pilot) |
-| #673 | Deterministic Morrowind pilot loop |
-| #674 | Reflex tactical layer + trajectory logging |
-| #675 | Deterministic context compaction |
+## Verified historical browser-world snapshot
+
+The commit the user pointed at:
+- `0518a1c3ae3c1d0afeb24dea9772102f5a3d9a66`
+
+still contains the old root browser files (`index.html`, `app.js`, `style.css`, `package.json`, tests/), so it is a useful in-repo reference point for what existed before the later deletions.
+
+## Active migration backlog
+
+- `#684` sync docs to repo truth
+- `#685` preserve legacy Matrix quality work before rewrite
+- `#686` rebuild browser smoke / visual validation for the real Nexus repo
+- `#687` restore a wizardly local-first visual shell from audited Matrix components
+- `#672` rebuild the portal stack as Timmy → Reflex → Pilot
+- `#673` deterministic Morrowind pilot loop with world-state proof
+- `#674` reflex tactical layer and semantic trajectory logging
+- `#675` deterministic context compaction for long local sessions
+
+## What gets preserved from legacy Matrix
+
+High-value candidates include:
+- visitor movement / embodiment
+- chat, bark, and presence systems
+- transcript logging
+- ambient / visual atmosphere systems
+- economy / satflow visualizations
+- smoke and browser validation discipline
+
+Those pieces should be carried forward only if they serve the mission and are re-tethered to real local system state.

 ## Running Locally

-There is no root browser app on current `main`. Do not static-serve the repo root expecting a world.
+### Current repo truth

-You can run:
- `python3 server.py` — local websocket bridge
- Python modules under `nexus/` — heartbeat / cognition work
+There is no root browser app on current `main`.
+Do not tell people to static-serve the repo root and expect a world.

-The browser-facing Nexus must be rebuilt through the migration backlog using audited Matrix components.
