fix: [UI] Add first Nexus operator panel for Evennia room snapshot (closes #728)

- New component: nexus/components/evennia-room-panel.js (IIFE module)
- Renders room title + description, exits, objects, occupants
- Handles three honest states: offline, awaiting, in-room
- Listens for evennia.room_snapshot and evennia.actor_located WS events
- Integrates into handleHermesMessage dispatch + WS connect/disconnect lifecycle
- Styled to match existing Nexus HUD design system (JetBrains Mono, primary/secondary colors)
- aria-live='polite' for accessibility
- Syntax validated: node --check passed on all JS files

+Preserve useful work from `/Users/apayne/the-matrix` before the Nexus browser shell is rebuilt.
 
 Canonical rule:
 - `Timmy_Foundation/the-nexus` is the only canonical 3D repo.
 - `/Users/apayne/the-matrix` is legacy source material, not a parallel product.

-## Migration Table
+## Known historical Nexus snapshot
 
-Decision key:
-- **CARRY** = transplant concepts and patterns into Nexus vNext
-- **ARCHIVE** = keep as reference, do not directly transplant
-- **DROP** = do not preserve unless re-justified
+Useful in-repo reference point:
+- `0518a1c3ae3c1d0afeb24dea9772102f5a3d9a66`
 
-### Core Modules
+That snapshot still contains browser-world root files such as:
+- `index.html`
+- `app.js`
+- `style.css`
+- `package.json`
+- `tests/`
 
-| File | Lines | Capability | Decision | Why for Nexus |
-|------|-------|------------|----------|---------------|
-| `js/main.js` | 180 | App bootstrap, render loop, WebGL context recovery | **CARRY** | Architectural pattern. Shows clean init/teardown lifecycle, context-loss recovery, visibility pause. Nexus needs this loop but should not copy the monolithic wiring. |
-| `js/world.js` | 95 | Scene, camera, renderer, grid, lights | **CARRY** | Foundational. Quality-tier-aware renderer setup, grid floor, lighting. Nexus already has a world but should adopt the tier-aware antialiasing and pixel-ratio capping. |
-| `js/config.js` | 68 | Connection config via URL params + env vars | **ARCHIVE** | Pattern reference only. Nexus config should route through Hermes harness, not Vite env vars. The URL-override pattern (ws, token, mock) is worth remembering. |
-| `js/quality.js` | 90 | Hardware detection, quality tier (low/medium/high) | **CARRY** | Directly useful. DPR capping, core/memory/screen heuristics, WebGL renderer sniffing. Nexus needs this for graceful degradation on Mac/iPad. |
-| `js/storage.js` | 39 | Safe localStorage with in-memory fallback | **CARRY** | Small, robust, sandbox-proof. Nexus should use this or equivalent. Prevents crashes in sandboxed iframes. |
+## Rescue Candidates
 
-### Agent System
+### Carry forward into Nexus vNext
 
-| File | Lines | Capability | Decision | Why for Nexus |
-|------|-------|------------|----------|---------------|
-| `js/agent-defs.js` | 30 | Agent identity data (id, label, color, role, position) | **CARRY** | Seed data model. Nexus agents should be defined similarly — data-driven, not hardcoded in render logic. Color hex helper is trivial but useful. |
-| `js/agents.js` | 523 | Agent 3D objects, movement, state, connection lines, hot-add/remove | **CARRY** | Core visual system. Shared geometries (perf), movement interpolation, wallet-health stress glow, auto-placement algorithm, connection-line pulse. All valuable. Needs integration with real agent state from Hermes. |
-| `js/behaviors.js` | 413 | Autonomous agent behavior state machine | **ARCHIVE** | Pattern reference. The personality-weighted behavior selection, conversation pairing, and artifact-placement system are well-designed. But Nexus behaviors should be driven by Hermes, not a client-side simulation. Keep the architecture, drop the fake-autonomy. |
-| `js/presence.js` | 139 | Agent presence HUD (online/offline, uptime, state) | **CARRY** | Valuable UX. Live "who's here" panel with uptime tickers and state indicators. Needs real backend state, not mock assumptions. |
+1. `agent-defs.js`
+- agent identity definitions
+- useful as seed data/model for visible entities in the world
 
-### Visitor & Interaction
+2. `agents.js`
+- agent objects, state machine, connection lines
+- useful for visualizing Timmy / subagents / system processes in a world-native way
 
-| File | Lines | Capability | Decision | Why for Nexus |
-|------|-------|------------|----------|---------------|
-| `js/visitor.js` | 141 | Visitor enter/leave protocol, chat input | **CARRY** | Session lifecycle. Device detection, visibility-based leave/return, chat input wiring. Directly applicable to Nexus visitor tracking. |
-| `js/avatar.js` | 360 | FPS movement, PiP dual-camera, touch input | **CARRY** | Visitor embodiment. WASD + arrow movement, first/third person swap, PiP canvas, touch joystick, right-click mouse-look. Strong work. Needs tuning for Nexus world bounds. |
-| `js/interaction.js` | 296 | Raycasting, click-to-select agents, info popup | **CARRY** | Essential for any browser world. OrbitControls, pointer/tap detection, agent popup with state/role, TALK button. The popup-anchoring-to-3D-position logic is particularly well done. |
-| `js/zones.js` | 161 | Proximity trigger zones (portal enter/exit, events) | **CARRY** | Spatial event system. Portal traversal, event triggers, once-only zones. Nexus portals (#672) need this exact pattern. |
+3. `avatar.js`
+- visitor embodiment, movement, camera handling
+- strongly aligned with "training ground" and "walk the world" goals
 
-### Chat & Communication
+4. `ui.js`
+- HUD, chat surfaces, overlays
+- useful if rebuilt against real harness data instead of stale fake state
 
-| File | Lines | Capability | Decision | Why for Nexus |
-|------|-------|------------|----------|---------------|
-| `js/bark.js` | 141 | Speech bubble system with typing animation | **CARRY** | Timmy's voice in-world. Typing animation, queue, auto-dismiss, emotion tags, demo bark lines. Strong expressive presence. The demo lines ("The Tower watches. The Tower remembers.") are good seed content. |
-| `js/ui.js` | 285 | Chat panel, agent list, HUD, streaming tokens | **CARRY** | Chat infrastructure. Rolling chat buffer, per-agent localStorage history, streaming token display with cursor animation, HTML escaping. Needs reconnection to Hermes chat instead of WS mock. |
-| `js/transcript.js` | 183 | Conversation transcript logger, export | **ARCHIVE** | Pattern reference. The rolling buffer, structured JSON entries, TXT/JSON download, HUD badge are all solid. But transcript authority should live in Hermes, not browser localStorage. Keep the UX pattern, rebuild storage layer. |
+5. `websocket.js`
+- browser-side live bridge patterns
+- useful if retethered to Hermes-facing transport
 
-### Visual Effects
+6. `transcript.js`
+- local transcript capture pattern
+- useful if durable truth still routes through Hermes and browser cache remains secondary
 
-| File | Lines | Capability | Decision | Why for Nexus |
-|------|-------|------------|----------|---------------|
-| `js/effects.js` | 195 | Matrix rain particles + starfield | **CARRY** | Atmospheric foundation. Quality-tier particle counts, frame-skip optimization, adaptive draw-range (FPS-budget recovery), bounding-sphere pre-compute. This is production-grade particle work. |
-| `js/ambient.js` | 212 | Mood-driven atmosphere (lighting, fog, rain, stars) | **CARRY** | Scene mood engine. Smooth eased transitions between mood states (calm, focused, excited, contemplative, stressed), per-mood lighting/fog/rain/star parameters. Directly supports Nexus atmosphere. |
-| `js/satflow.js` | 261 | Lightning payment particle flow | **CARRY** | Economy visualization. Bezier-arc particles, staggered travel, burst-on-arrival, pooling. If Nexus shows any payment/economy flow, this is the pattern. |
+7. `ambient.js`
+- mood / atmosphere system
+- directly supports wizardly presentation without changing system authority
 
-### Economy & Scene
+8. `satflow.js`
+- visual economy / payment flow motifs
+- useful if Timmy's economy/agent interactions become a real visible layer
 
-| File | Lines | Capability | Decision | Why for Nexus |
-|------|-------|------------|----------|---------------|
-| `js/economy.js` | 100 | Wallet/treasury HUD panel | **ARCHIVE** | UI pattern reference. Clean sats formatting, per-agent balance rows, health-colored dots, recent transactions. Worth rebuilding when backed by real sovereign metrics. |
-| `js/scene-objects.js` | 718 | Dynamic 3D object registry, portals, sub-worlds | **CARRY** | Critical. Geometry/material factories, animation system (rotate/bob/pulse/orbit), portal visual (torus ring + glow disc + zone), sub-world load/unload, text sprites, compound groups. This is the most complex and valuable module. Nexus portals (#672) should build on this. |
+9. `economy.js`
+- treasury / wallet panel ideas
+- useful if later backed by real sovereign metrics
 
-### Backend Bridge
+10. `presence.js`
+- who-is-here / online-state UI
+- useful for showing human + agent + process presence in the world
 
-| File | Lines | Capability | Decision | Why for Nexus |
-|------|-------|------------|----------|---------------|
-| `js/websocket.js` | 598 | WebSocket client, message dispatcher, mock mode | **ARCHIVE** | Pattern reference only. Reconnection with exponential backoff, heartbeat/zombie detection, rich message dispatch (40+ message types), streaming chat support. The architecture is sound but must be reconnected to Hermes transport, not copied wholesale. The message-type catalog is the most valuable reference artifact. |
-| `js/demo.js` | ~300 | Demo autopilot (mock mode simulation) | **DROP** | Fake activity simulation. Deliberately creates the illusion of live data. Do not preserve. If Nexus needs a demo mode, build a clearly-labeled one that doesn't pretend to be real. |
+11. `interaction.js`
+- clicking, inspecting, selecting world entities
+- likely needed in any real browser-facing Nexus shell
 
-### Testing & Build
+12. `quality.js`
+- hardware-aware quality tiering
+- useful for local-first graceful degradation on Mac hardware
 
-| File | Lines | Capability | Decision | Why for Nexus |
-|------|-------|------------|----------|---------------|
-| `test/smoke.mjs` | 235 | Automated browser smoke test suite | **CARRY** | Testing discipline. Module inventory check, export verification, HTML structure validation, Vite build test, bundle-size budget, PWA manifest check. Nexus should adopt this pattern (adapted for its own module structure). |
-| `vite.config.js` | 53 | Build config with code splitting, SW generation | **ARCHIVE** | Build tooling reference. manualChunks for Three.js, SW precache generation plugin. Relevant if Nexus re-commits to Vite. |
-| `sw.js` | ~40 | Service worker with precache | **ARCHIVE** | PWA reference. Relevant only if Nexus pursues offline-first PWA. |
-| `manifest.json` | ~20 | PWA manifest | **ARCHIVE** | PWA reference. |
+13. `bark.js`
+- prominent speech / bark system
+- strong fit for Timmy's expressive presence in-world
 
-### Server-Side (Python)
+14. `world.js`, `effects.js`, `scene-objects.js`, `zones.js`
+- broad visual foundation work
+- should be mined for patterns, not blindly transplanted
 
-| File | Lines | Capability | Decision | Why for Nexus |
-|------|-------|------------|----------|---------------|
-| `server/bridge.py` | ~900 | WebSocket bridge server | **ARCHIVE** | Reference. Hermes replaces this role. Keep for protocol schema reference. |
-| `server/gateway.py` | ~400 | HTTP gateway | **ARCHIVE** | Reference. |
-| `server/ollama_client.py` | ~280 | Ollama integration | **ARCHIVE** | Reference. Relevant if Nexus needs local model calls. |
-| `server/research.py` | ~450 | Research pipeline | **ARCHIVE** | Reference. |
-| `server/webhooks.py` | ~350 | Webhook handler | **ARCHIVE** | Reference. |
-| `server/test_*.py` | ~5 files | Server test suites | **ARCHIVE** | Testing patterns worth studying. |
+15. `test/smoke.mjs`
+- browser smoke discipline
+- should inform rebuilt validation in canonical Nexus repo
 
-## Summary by Decision
+### Archive as reference, not direct carry-forward
 
-### CARRY FORWARD (17 modules)
-These modules contain patterns, algorithms, or entire implementations that should move into the Nexus browser shell:
+- demo/autopilot assumptions that pretend fake backend activity is real
+- any websocket schema that no longer matches Hermes truth
+- Vite-specific plumbing that is only useful if we consciously recommit to Vite
 
-- `quality.js` — hardware detection
-- `storage.js` — safe persistence
-- `world.js` — scene foundation
-- `agent-defs.js` — agent data model
-- `agents.js` — agent visualization + movement
-- `presence.js` — online presence HUD
-- `visitor.js` — session lifecycle
-- `avatar.js` — FPS embodiment
-- `interaction.js` — click/select/raycast
-- `zones.js` — spatial triggers

-- `effects.js` — particle effects
-- `ambient.js` — mood atmosphere
-- `satflow.js` — payment flow particles
-- `scene-objects.js` — dynamic objects + portals
-- `test/smoke.mjs` — smoke test discipline
+### Deliberately drop unless re-justified
 
-### ARCHIVE AS REFERENCE (9 modules/files)
-Keep for patterns, protocol schemas, and architectural reference. Do not directly transplant:
-
-- `config.js` — config pattern (use Hermes instead)
-- `behaviors.js` — behavior architecture (use Hermes-driven state)
-- `transcript.js` — transcript UX (use Hermes storage)
-- `economy.js` — economy UI pattern (use real metrics)
-- `websocket.js` — message protocol catalog + reconnection patterns
-- `vite.config.js` — build tooling
-- `sw.js`, `manifest.json` — PWA reference
-- `server/*.py` — server protocol schemas
-
-### DELIBERATELY DROP (2)
-Do not preserve unless re-justified:
-
-- `demo.js` — fake activity simulation; creates false impression of live system
-- `main.js` monolithic wiring — the init pattern carries, the specific module wiring does not
+- anything that presents mock data as if it were live
+- anything that duplicates a better Hermes-native telemetry path
+- anything that turns the browser into the system of record
 
 ## Concern Separation for Nexus vNext
 
-When rebuilding inside `the-nexus`, keep these concerns in separate modules:
+When rebuilding inside `the-nexus`, keep concerns separated:
 
-1. **World shell** — scene, camera, renderer, grid, lights, fog
-2. **Effects layer** — rain, stars, ambient mood transitions
-3. **Agent visualization** — 3D objects, labels, connection lines, movement
-4. **Visitor embodiment** — avatar, FPS controls, PiP camera
-5. **Interaction layer** — raycasting, selection, zones, portal traversal
-6. **Communication surface** — bark, chat panel, streaming tokens
-7. **Presence & HUD** — who's-online, economy panel, transcript controls
-8. **Harness bridge** — WebSocket/API transport to Hermes (NOT a copy of websocket.js)
-9. **Quality & config** — hardware detection, runtime configuration
-10. **Smoke tests** — automated validation
+1. World shell / rendering
+- scene, camera, movement, atmosphere
+
+2. Presence and embodiment
+- avatar, agent placement, selection, bark/chat surfaces
+
+3. Harness bridge
+- websocket / API bridge from Hermes truth into browser state
+
+4. Visualization panels
+- metrics, presence, economy, portal states, transcripts
+
+5. Validation
+- smoke tests, screenshot proof, provenance checks
+
+6. Game portal layer
+- Morrowind / portal-specific interaction surfaces
 
 Do not collapse all of this into one giant app file again.
 Do not let visual shell code become telemetry authority.
