Add Evennia-fed visual proof smoke tests

- Update app.js WebSocket endpoint to fixed ws://127.0.0.1:8765
  to match BROWSER_CONTRACT (no path proxy needed locally.
- Extend test_browser_smoke.py:
  * Add ws_server fixture to run server.py
  * Add evennia_page fixture for WS-connected browser
  * Add TestOfflineState (honest offline behavior)
  * Add TestEvenniaFeed with WS connection check, ERP population
    verification from injected room_snapshot, and screenshot proof.

Fixes #731 – Browser smoke + visual proof for Evennia-fed Nexus shell.

+# Minimum Sovereign Hardware Requirements
+
+## The Nexus — Three.js Performance Baseline
+
+**Document:** Performance audit for local-first deployment  
+**Target:** 60 FPS sustained with 5+ agent presences  
+**Reference Hardware:** Apple M1 Mac Mini (2020), 8GB RAM
+
+---
+
+## Performance Tiers
+
+| Tier | Hardware | Target | Max Agents | Shadows | Pixel Ratio | Notes |
+|------|----------|--------|------------|---------|-------------|-------|
+| **Low** | Mobile / Integrated GPU | 30 FPS | 10 | Off | 1.0 | iPhone, Intel UHD |
+| **Medium** | M1 Mac / Mid-range | **60 FPS** | 25 | Basic | 1.5 | **Baseline standard** |
+| **High** | M2+/Dedicated GPU | 60+ FPS | 50+ | Soft PCF | 2.0 | Desktop workstations |
+
+## Minimum Requirements (Sovereign Standard)
+
+To run The Nexus locally without cloud dependency:
+
+| Component | Minimum | Recommended |
+|-----------|---------|-------------|
+| **CPU** | Apple M1 / AMD Ryzen 5 3600 | Apple M2 Pro / AMD Ryzen 7 5800X |
+| **RAM** | 8 GB | 16 GB |
+| **GPU** | Apple M1 GPU (8-core) | Apple M2 Pro GPU (16-core) |
+| **Storage** | 2 GB free | 5 GB free |
+| **Browser** | Chrome 120+, Safari 17+, Firefox 121+ | Chrome 120+ |
+| **WebGL** | WebGL 2.0 | WebGL 2.0 |
+
+## Performance Optimizations Applied
+
+### 1. Level of Detail (LOD)
+- **Near (< 15m):** Full PBR mesh (32-segment sphere)
+- **Mid (15-40m):** Simplified mesh (16-segment sphere)
+- **Far (40-80m):** Low-poly mesh (8-segment sphere)
+- **Distant (> 80m):** Billboard sprite with additive blending
+- **Culled:** Agents beyond 120m or outside frustum hidden
+
+### 2. Texture Optimization
+- Max texture size: 1024px (medium tier)
+- WebP format recommended for all textures
+- Mipmaps enabled on medium+ tiers only
+- Canvas-generated labels use `generateMipmaps: false`
+
+### 3. Renderer Settings by Tier
+
+```javascript
+// Low (mobile/integrated)
+renderer.setPixelRatio(1);
+renderer.shadowMap.enabled = false;
+renderer.toneMapping = THREE.NoToneMapping;
+
+// Medium (M1 Mac baseline)
+renderer.setPixelRatio(Math.min(window.devicePixelRatio, 1.5));
+renderer.shadowMap.enabled = true;
+renderer.shadowMap.type = THREE.BasicShadowMap;
+
+// High (dedicated GPU)
+renderer.setPixelRatio(Math.min(window.devicePixelRatio, 2));
+renderer.shadowMap.enabled = true;
+renderer.shadowMap.type = THREE.PCFSoftShadowMap;
+```
+
+### 4. Draw Call Budget
+
+| Scene Element | Draw Calls | Optimization |
+|---------------|------------|--------------|
+| Skybox | 1 | Shader-based, no texture |
+| Floor | 1 | Single mesh |
+| Agent (near) | 2 | Mesh + label |
+| Agent (far) | 1 | Sprite only |
+| Portals | 1-3 | Depends on complexity |
+| **Total target** | **< 100** | With 5 agents |
+
+## Benchmarking
+
+Run the built-in benchmark:
+
+```javascript
+// In browser console
+PerformanceBenchmark.run(10000); // 10-second test
+PerformanceBenchmark.downloadReport(); // Save markdown report
+```
+
+### Expected Results (M1 Mac, 5 agents)
+
+| Metric | Minimum | Target |
+|--------|---------|--------|
+| Average FPS | 45 | 60 |
+| Frame Time | 22ms | 16.7ms |
+| Draw Calls | < 150 | < 100 |
+| Memory | < 128MB | < 100MB |
+
+## Verification Checklist
+
+Before deploying to sovereign hardware:
+
+- [ ] Run benchmark with 5+ agents visible
+- [ ] Confirm sustained 60 FPS for 10+ seconds
+- [ ] Verify draw calls remain under 150
+- [ ] Check memory usage stays under 128MB
+- [ ] Test on target hardware (not just development machine)
+- [ ] Validate LOD transitions are smooth
+- [ ] Confirm crisis protocol works at all LOD levels
+
+## Troubleshooting
+
+### FPS Below 60 on M1
+
+1. Check `PerformanceMonitor` (Shift+P) for draw calls
+2. Reduce `LODSystem` thresholds: `LODSystem.forceTier('low')`
+3. Disable post-processing effects
+4. Reduce agent count or draw distance
+
+### High Memory Usage
+
+1. Run `TextureOptimizer.auditScene(scene)`
+2. Check for uncompressed textures
+3. Reduce texture size limits: `TextureOptimizer.SIZE_LIMITS.medium = 512`
+
+### Stuttering
+
+1. Check for garbage collection pauses
+2. Reduce object creation in render loop
+3. Enable `renderer.info.autoReset = false` and manual reset

+# Nostr Migration Consolidation Plan
+
+> Issue #862 | Canonical Epic: the-nexus #819  
+> Consolidated From: the-nexus #819 + timmy-config #138
+
+---
+
+## Problem
+
+Two epics tracked the same Telegram -> Nostr migration with overlapping scope:
+
+| Epic | Repo | Focus | Status |
+|------|------|-------|--------|
+| #819 | the-nexus | Client fork (Nostur), UI/UX, agent presence | **CANONICAL** |
+| #138 | timmy-config | Relay/infrastructure, deployment, ops | Tracked child |
+
+Neither was the parent. Work risked duplication and drift.
+
+---
+
+## Resolution
+
+**#819 is the canonical parent epic.** All Nostr migration work rolls up here.
+
+### Scope Boundaries
+
+| Component | Owner Repo | Epic / Issue |
+|-----------|-----------|--------------|
+| Nostur client fork | the-nexus | #819 |
+| Agent Nostr presence (JS) | the-nexus | #819 |
+| Relay deployment & infra | timmy-config | #138 (child of #819) |
+| Key management (NIP-49) | timmy-config | #138 (child of #819) |
+| Telegram-Nostr bridge | **NEW** | File as child of #819 |
+| Nostr identity (Python) | the-nexus | #819 |

+    +-- Graceful Telegram deprecation path
+```
+
+---
+
+## Current Implementation State
+
+### Python Stack (the-nexus)
+- `nexus/nostr_identity.py` - Pure-Python BIP340 Schnorr signatures
+  - WARNING **Timing side-channel vulnerabilities** (see FINDINGS-issue-801.md)
+  - Suitable for prototyping; production needs `coincurve` or constant-time rewrite
+- `nexus/nostr_publisher.py` - Async WebSocket publisher to public relays
+
+### Browser Stack (the-nexus)
+- `app.js:NostrAgent` - Browser-side agent presence
+  - WARNING Uses **mock signatures** (`mock_id`, `mock_sig`)
+  - Needs real crypto integration or delegation to Python backend
+
+### Infrastructure (timmy-config)
+- `nostr-bridge.service` - Running but source file deleted, only `.pyc` remains
+- `/root/nostr-relay/keystore.json` - NIP-49 encrypted nsec storage
+
+---
+
+## Highest Priority: Telegram-Nostr Bridge
+
+The bridge is the critical path. Without it, migration strands users on Telegram.
+
+**Requirements:**
+1. Bidirectional message relay (Telegram <-> Nostr)
+2. Dual-presence period: both platforms active during transition
+3. Graceful deprecation: Telegram bot stays online until 90% of active users have Nostr handles
+4. Channel/topic mapping: preserve conversation structure
+
+**File this as a new child issue under #819.**
+
+---
+
+## Action Items
+
+- [ ] Close #138 in timmy-config with comment: "Consolidated into the-nexus #819. Relay/infrastructure work tracked as child of canonical epic."
+- [ ] Update #819 title/body to reference this consolidation plan
+- [ ] File child issue: Telegram-Nostr bridge (bidirectional, dual-presence)
+- [ ] File child issue: Fix timing side-channel in `nostr_identity.py` (or replace with `coincurve`)
+- [ ] File child issue: Replace mock signatures in `app.js:NostrAgent` with real crypto
+- [ ] Assign owners to each child issue

+# Telegram-Nostr Bridge Specification
+
+> Child of Epic #819 (Operation Exodus: Telegram -> Nostr Migration)
+> Priority: HIGHEST
+
+---
+
+## Overview
+
+Bidirectional message relay between Telegram and Nostr during the migration period.
+Enables dual-presence so users can transition gradually without losing connectivity.
+
+---
+
+## Requirements
+
+### Functional
+
+1. **Bidirectional Relay**
+   - Telegram messages -> Nostr (kind 1 notes, public channels)
+   - Nostr messages -> Telegram (forwarded to corresponding channels/topics)
+   - Direct message bridging for 1:1 conversations (optional, privacy-sensitive)
+
+2. **Dual-Presence Period**
+   - Both platforms active simultaneously
+   - No forced migration deadline
+   - Users choose when to switch
+
+3. **Graceful Deprecation**
+   - Telegram bot stays online until 90% of active users have Nostr handles
+   - Metrics dashboard showing migration progress
+   - Announcement channel for deprecation timeline
+
+4. **Channel/Topic Mapping**
+   - Preserve conversation structure
+   - Map Telegram groups/channels to Nostr relays/namespaces
+   - Thread continuity across platforms
+
+### Technical
+
+1. **Nostr Side**
+   - Publish to configured relays (damus.io, nos.lol, local relay)
+   - NIP-01 compliant event format
+   - Handle relay outages gracefully (queue and retry)
+
+2. **Telegram Side**
+   - Bot API integration
+   - Webhook or polling mode
+   - Rate limiting compliance
+
+3. **Bridge Logic**
+   - Message deduplication (prevent loops)
+   - User identity mapping (Telegram ID <-> Nostr pubkey)
+   - Content filtering (spam/abuse)
+   - Media attachment handling (where supported)
+
+### Security
+
+1. **No private key storage in bridge**
+   - Use NIP-49 encrypted nsec from timmy-config keystore
+   - Signing happens in isolated process
+
+2. **Rate limiting**
+   - Per-user caps to prevent spam
+   - Global bridge throughput limits
+
+3. **Audit logging**
+   - All bridged messages logged for 30 days
+   - Log rotation and cleanup
+
+---
+
+## Architecture
+
