Scope

Resolve the critical issue of Timmy showing permanent "OFFLINE" status and implement graceful GPU context loss handling.

Requirements

  • Diagnose and fix why Timmy displays OFFLINE — this is the core value proposition blocker
  • Implement WebGL context loss detection with graceful recovery (not raw error messages)
  • User-friendly error states: "Timmy is taking a quick break — back in a moment" with auto-retry
  • Fallback for devices without WebGL support: 2D interface or text-only mode
  • Handle GPU memory limits: progressive quality reduction before context loss
  • Mobile detection: redirect to appropriate experience instead of broken 3D

Deliverable

Timmy shows ONLINE with functional AI interaction; GPU errors handled gracefully.

PR created: #1337

Changes made:

  1. base.html — OFFLINE status bug fixed: connectStatusWs() had catch(e) { return; } which permanently gave up reconnection if the WebSocket constructor threw (e.g. in some network environments). Now retries with exponential backoff like the onclose handler does. Changed label from OFFLINE → Reconnecting... so it accurately reflects the auto-retry behaviour.

  2. static/world/index.html — WebGL context loss + fallbacks:

    • WebGL support detection before renderer init — shows text-only fallback for unsupported browsers
    • Mobile detection (coarse pointer + < 768px) — shows text fallback instead of broken 3D scene
    • webglcontextlost / webglcontextrestored handlers — shows friendly "Timmy is taking a quick break" overlay, halts animation loop, resumes cleanly on restore
    • Fallback view stays live-synced via the state reader WebSocket

  3. static/world/style.css — new #gpu-error-overlay and #webgl-fallback styles

PR created: #1337 **Changes made:** 1. **`base.html` — OFFLINE status bug fixed**: `connectStatusWs()` had `catch(e) { return; }` which permanently gave up reconnection if the WebSocket constructor threw (e.g. in some network environments).
